Stackable molded container made of a thermoplastic with a handle

Description

Technical area

The present disclosure relates to a molded container, in particular a blow molded container, for holding a preparation, in particular a medical and/or pharmaceutical preparation, and for vertical stacking during transport and/or storage made of a thermoplastic material which has a handle. Furthermore, the present disclosure relates to an associated vertical stacking arrangement or a stacking system made of the molded containers according to the disclosure with the handle. Furthermore, an associated method for producing the molded container according to the disclosure with the handle and a use of the molded container according to the disclosure with the handle and/or the associated stacking arrangement for receiving and/or transporting and/or storing the, in particular medical and/or pharmaceutical, preparation and/or proposed for the application-related provision of the preparation, in particular in a dialysis machine.

State of the art

Molded containers, in particular blow molded containers, which are made from a thermoplastic such as polyethylene terephthalate (PET) with thin walls / recyclable, are currently used primarily in the area of beverage bottles, for example for filling mineral water, and also as canisters for liquid cleaning/detergents , everyday solutions and the like, ie for use in the domestic or industrial sector. On the other hand, the plastic containers or canisters conventionally used for medical and/or pharmaceutical preparations, in particular for dialysis solutions Z concentrates, are solid, thick-walled containers that are primarily manufactured using the (standard) injection molding process. As a result, there is the problem that these solid, thick-walled, especially (standard) injection-molded plastic containers require a high use of plastic materials. As a result, raw material costs, environmental impact, energy use, machine investments and recycling costs are unfavorably high.

Utility model CN 204618983 discloses a use of a bias-shaped PET container for filling a hemodialysis fluid. In order to improve quality in production, it is proposed to provide an inner rib structure that protrudes into the inside of the PET container and is partially undercut as a type of flow breaker arrangement. As a result, the flow behavior of the hemodialysis fluid should be changed in such a way that any splashing onto the outside of the PET container is avoided, especially when it is filled in production, in order to avoid contamination that could impair its quality.

Also disclosed in CN 204618983 is an (injection molded) carrying handle attached to a bottle mouth or a container neck. The carrying handle consists of a ring body which is placed on the neck of the bottle mouth with an outer diameter, the ring body having an inner ring provided with friction teeth and a handle attached to the outside of the ring body.

However, from the perspective of vertical stacking, the technical problem arises of providing a suitable (carrying) handle on the container. For this purpose, the handle must primarily not be sterically disruptive with regard to vertical stacking, i.e., must not come into a contact surface between two identical stackable containers (ie into the contact surface of a bottom surface of an upper container with a shoulder surface of a lower container). Ideally one is To provide a handle that does not require or even forces specific recesses to be provided in the contact surface.

In this respect, side handles in particular are proposed in the prior art. In most cases, the side handles are integrally bias-shaped, as is known, for example, from US 4846359 with regard to a bias-shaped bottle for fruit juice. Further, WO 98/05566 discloses a bias-molded plastic container with an inwardly directed lateral recess and with a separately molded plastic handle permanently secured over the recess by welding techniques at thickened areas of the plastic container. However, these side handles have several disadvantages. First of all, the lateral molding or recess results in instabilities or impairments with regard to the molding production (more complicated mold design, thus increased investment and manufacturing costs, reduced cycle times, etc.). Furthermore, experience has shown that the mechanical (storage) stability of the container as a primary packaging medium is negatively affected, particularly in the case of integral handles, due to the lateral seam division of the container caused by the tool demoulding, which is a structural weak point in the material.

Such a design with a side-mounted (carrying) handle is even more ergonomically unfavorable. In this respect, when carrying such containers upright, the vertical force of gravity or primary pulling component acts more transversely to the handle section, which is uncomfortable on the wrist. On the other hand, when carrying such containers lying down to avoid the body-hand position described above, the liquid they contain can slosh back and forth, which is also disadvantageous to a container closure. In particular, in the case of side handles, experience has shown that it is ergonomically difficult to carry more than one container, which impractically slows down logistical processes, especially in everyday clinical practice.

In addition, the handle should be made of as little material as possible in order to conserve resources, protect the environment and save costs. Solid, especially injection molded, handles known from the prior art (especially as separate ones Purchased parts), however, due to their solid construction, require a lot of material and production energy.

Furthermore, in the prior art there is a need for a handle which not only shows positive application properties in production as well as during carrying or transport, but ideally is also useful for securing the container (in position) in a clinical application, in particular .in a dialysis machine.

Summary of Revelation

In view of the prior art described above, the present disclosure is intended to provide a container which is improved in terms of a (carrying) handle and is made of a preferably thermoplastic material for holding a preparation, in particular a medical and/or pharmaceutical preparation, and for vertical stacking during transport and/or Provide storage that overcomes the disadvantages of the prior art.

According to a first aspect of the present disclosure, this is achieved by a molding container, in particular a blow molding container, with a handle according to the features of claim 1 and preferably by an associated vertical stacking arrangement or a stacking system according to the dependent claim directed thereon, more preferably by an associated method Production of the molded container according to the disclosure, in particular blow molded container, with the handle handle according to the dependent claim directed thereon and further preferably by using the molded container according to the disclosure, in particular blow molded container, with the handle handle and / or the associated stacking arrangement for receiving and / or transport and / or storage the medical and/or pharmaceutical preparation and/or for the (application-related) provision of the preparation, in particular in a dialysis machine, according to the dependent claim directed thereto. Preferred or advantageous embodiments of the disclosure emerge from the subclaims, the following description and the attached figures. According to the present core of the disclosure, the following subject matter arises:

Molded container, in particular blow molded container, made of a thermoplastic (or molded container produced in a thermoplastic molding process) for receiving a medical and / or pharmaceutical preparation (set up), which has a bottom section at one end of a fuselage section, in particular with a frontal bottom surface of the bottom section; and a shoulder portion at the axially opposite other end of the torso portion. The molded container, in particular with regard to the base section and the shoulder section (or these to each other), is shaped and/or fit and/or set up in such a way that two (essentially) identical (or similar) molded containers for transport and/or storage are vertical ( can be stacked on top of each other.

Essential to the disclosure (according to the present aspect, which represents an aspect independent of preferred shape features of the mold container or the bottom section and the shoulder section), a handle is attached to the mold container, in particular a blow mold container. In particular, the handle handle is attached with its two opposite handle handle ends to two associated connection points of two opposite outer lateral surfaces of the mold container. In particular, the handle handle with its two opposite handle ends is attached tangentially to the two associated connection points. In particular, the connection points (such) can be arranged by or on two opposite outer lateral surfaces of the fuselage section. In particular, the handle handle is attached, more preferably firmly connected and/or attached and/or glued, in order to form a handle handle center section which runs between the handle handle ends and axially beyond the shoulder section, in particular in the shape of a round bow.

In other words, the molded container according to the disclosure, in particular blow molded container, for holding a preparation, in particular a medical and/or pharmaceutical preparation, and for vertical stacking, for example during transport and/or storage, is made of a thermoplastic Plastic (such as PET, etc.) furnished. In other words, the molded container according to the disclosure is designed or shaped in such a way that two identical molded containers can be stacked vertically. The molding container, in particular a blow molding container, has a bottom section (container base) at one end of a body section and a shoulder section (container roof) at the axially opposite other end of the body section. In this case, the molded container has the handle handle arranged or attached to it, which is essential to the disclosure.

According to the aforementioned, presently claimed or disclosure-essential embodiment according to claim 1, with the handle as the carrying handle or handle element (with reference to the associated Figures 9 and 10 relating to a preferred embodiment of the molded container with the handle), material can be saved in an advantageous manner become. This is particularly true in comparison to an injection-molded handle with a strong three-dimensional shape.

Furthermore, the technical advantage of the handle is that it can be attached very flexibly, i.e. virtually at any time along the production or logistics value chain. Due to the easy, tangential attachment to the openly accessible outer surface, special machine guides are advantageously not necessary, as are otherwise required due to the high attention forces of solid carrying handles.

In this regard, it should be noted that the person skilled in the art understands that the aforementioned feature regarding the handle is initially to be viewed as independent of a specific design of the mold container or its production. In particular, the present object of the molded container having the handle handle (according to claim 1) is also aimed at any container for any content, ie without necessarily the (hereinafter) alternatively or cumulatively preferred (optional) features of a blow molding production and / or a material made of thermoplastic material and/or a specific floor/shoulder contour (according to a further, possibly independent aspect). In this respect, the further, if necessary independently, is determined object to be stressed or the associated feature on a specific bottom-side shape structure or shape fit for vertical stackability (particularly with regard to a bottom-recess shape segment, etc., see below) as a technically independent task and solution with consequently independently achieved advantages, such as further disclosed below.

The person skilled in the art understands that the advantages which are disclosed according to the handle attached to mold containers (as a primary packaging means for the preparation) with the handle from the outside arise, in the first respect, regardless of a specific type or of a chemical and/or physical composition or an intended use of the preparation. Nevertheless, synergistic aspects are not excluded in a second respect, which can arise, for example, from the application technology of the specifically preferred preparation.

In this respect, in general, the preparation is not limited to a medical and/or pharmaceutical preparation. In other words, the term preparation includes all types, in particular those for or from the field of food and/or beverages, the agricultural industry, the chemical industry, commercial applications, detergents and cleaning agents, consumer goods, cosmetics, of diagnostics, of polymers, of paints, of perfumes and the like. Furthermore, the preparation can have at least one of the aggregate states, in particular a solid, for example powdery, form and/or a liquid form, for example an aqueous or organic solution of a solid and/or a gas such as, more preferably, a carbonated mineral water. Furthermore, the preparation can relate to a two- or multi-phase preparation, such as an emulsion (W/O or O/W) and/or a micellar solution and/or a foam.

In particular, alternatively or cumulatively, the handle handle can be designed, preferably at least in sections, flat, in particular as a foil strip-shaped handle handle (or as a flat carrying handle and / or from a flat structure and / or as a foil handle) (with reference to the associated , Figures 9 and 10 relating to this preferred embodiment with the foil strip-shaped handle handle. Alternatively or cumulatively, the handle can be formed, preferably at least in sections, from a rolled and/or corded material or the like. Both of the above-mentioned variants, as the person skilled in the art understands, advantageously enable cost-, energy- and resource-saving production of the handle. In particular, it is conceivable to produce the handle in a continuous process by cutting or cutting off a roll of film or (cord) tape and the like as a template (or a feed) in cycles and/or repeats. Very high production (belt) speeds or production volumes are advantageously conceivable. In particular, production volumes, based on machine and system investments for an injection-molded or integrally bias-molded handle, are significantly higher, ie cheaper.

Alternatively or cumulatively, the handle handle, in particular the film handle, can be formed, preferably at least in sections, using a soft, foam-like material (or another such layer). This advantageously leads to an increase in wearing comfort for a user due to the padding.

Preferred length and width dimensions of the, preferably flat, in particular film strip-shaped, handle handle can, in particular for an exemplary molded container, in particular blow molded container, with a nominal filling volume of 4.7 liters, preferably about 160 mm to 380 mm for the handle handle width and about 200 mm to 300 mm for the handle length.

Alternatively or cumulatively, the handle handle, in particular the flat handle handle or foil handle, can be glued to the two associated connection points, in particular glued using a self-adhesive layer and/or hot melt. Alternatively or cumulatively, the handle handle, in particular the flat handle handle or foil handle, can be attached to the or the two associated connection points, in particular be spot welded. This advantageously results in a reliable, long-term (storage) stable connection of the handle to the mold container. At the same time, the process step of attaching can advantageously be implemented in a cost-saving manner, either directly following a thermoplastic process with the process steps of thermoplastic forming or molding and then cooling the thermoplastically formed or shaped mold container for removal in its solidified state (i.e. downstream of a molding machine ) or indirectly afterwards in a separate, downstream process step for attaching the handle, for example in a (re)packaging station.

The molded container, in particular a blow molded container, is designed in particular to hold a medical and/or pharmaceutical preparation and in particular for vertical stacking during transport and/or storage made of a thermoplastic, in particular PET. The molding container, in particular blow molding container, in particular has a bottom section at one end of a body section and a shoulder section at the axially opposite other end of the body section. The shoulder section can (optionally) have a container neck in its axial extension. In particular, the container neck can be closed or closed with an (optional) closure. In a front bottom surface of the bottom section, a bottom trough can (optionally) be axially retracted into the interior of the container. In this case, the bottom trough can (optionally) be shape-fitted or set up for the stackability of the stackable molded containers, in particular blow molded containers, (or when stacking them to form a vertical stacking arrangement according to the second aspect of the disclosure below), a further, in particular closed, container neck. To pick up the container neck contactlessly. In this case, on the (optionally stackable) molded container, in particular blow molded container, a handle handle (essential to the object), preferably flat, especially in the form of a film strip, (optionally in addition to this a dimensionally stable molded handle) is attached, in particular glued or attached. The handle handle is in particular attached to form a handle handle center section that runs between the handle handle ends and axially beyond the shoulder section, in particular in the shape of a round bow. The handle handle with its two opposite handle ends, in particular tangentially, rests on two associated connection points of two opposite outer lateral surfaces of the (blow) molding container, in particular of the fuselage section.

These arrangement features have the respective and overall advantageous effect that the two handle ends (i.e. the opposite side of the adhesive strip, for example) counteract any unintentional removal by a user and the handle handle is held in position overall.

In particular, the, in particular flat, material or the flat structure of the flat, especially film-strip-shaped, handle handle can be a (particularly multi-layered) plastic film and/or a paper laminated with a plastic film and/or a fiber-reinforced composite material. Furthermore, the use of a combination of different (plastic) materials may be preferred. More preferably, the flat material can initially be folded in order to only unfold into its final form when in use. More preferably, the flat material or the flat structure can comprise, in particular, an elastic material and/or a shape memory material, whereby the handling of the molded container according to the disclosure, in particular a blow molded body Z container, is further simplified or improved in this preferred embodiment. In particular, the handle handle can be attached or fastened to the mold container, in particular blow mold container, in such a way that the handle handle rests in a metastable state on the mold container, in particular blow mold container, and protrudes from the mold container, in particular blow mold container, in a stable state.

Preferably, alternatively or cumulatively, a handle handle center section can be printable or printed, in particular with specific usage information and/or article names. This serves to provide (legally required) product labeling and user information in a technically simple manner.

Preferably, alternatively or cumulatively, the handle can be attached off-center with respect to the two connection points. In particular, the handle can be formed by a plumb point falling into a cross-sectional plane from the axial axis be mounted offset in a transverse direction. First of all, this improves vertical stackability. Furthermore, this improves ergonomics when carrying a pair of horizontally lying, especially stackable, identical molded containers.

Preferably, alternatively or cumulatively, the handle can be positioned obliquely to the axial axis in the two connection points. In particular, a handle handle setting angle defined between the axial axis (or vertical) and a longitudinal extension line of the handle handle can be in the angular range between 10 and 50 degrees, preferably between 30 and 40 degrees, even more preferably between 25 and 35 degrees [note with reference in Figure 10: the angle marked therein with the reference symbol “W” to the horizontal refers to the angle that supplements the right angle or 90°, starting from the handle handle setting angle (handle handle setting supplementary angle with the reference symbol “W”); therefore in the angular range between 80 and 40 degrees, preferably between 60 and 50 degrees, even more preferably between 65 and 55 degrees].

In addition to the very good handling of the molding container, in particular the blow molding container, this results in further advantages as follows: improvement in stackability (insofar as the carrying handle does not come into contact with the contact surface during vertical stacking or can disturb it); furthermore the possibility of attaching the molded container, in particular the blow molded container, for example by means of a suspension device of the dialysis machine; further improved residual quantity emptyingZ-removal of a contained (liquid) preparation, for example through a suction nozzleZ-lance of the dialysis machine, i.e. a minimization of the residual quantity that cannot be removed; and also an improvement in the manual carrying properties (more favorable center of gravity, the wearer's hand does not come into contact with the container neck Z (screw) cap).

In particular, the geometry chosen in this way in the attachment of the handle, ie with the off-center arrangement and Z or with the oblique angle of the handle handle, represents a significant improvement over previous (ie centrally attached and straight Z axially extending) solutions (as in the area of Beverage bottle multipacks or multiple containers are known, but with attachment to the outer shrink film secondary packaging that holds several beverage bottles together, ie not directly to the individual beverage bottle). As a result, the wearing properties are significantly improved.

In addition, it is advantageously avoided that the user's hand comes into contact with the remaining parts of the molding container, in particular the blow molding container. This results in an advantageous reduction in the associated risk of injury. In addition, the handle handle can be made significantly shorter when attached at an angle than when attached vertically (handle handle angle of 90°) in order to prevent the user's fingers from touching the closure when in use, which in turn leads to an advantageous saving of material in terms of the handle handle Film strips and the like that need to be cut to length. The person skilled in the art understands that, as an alternative and to a preferred/particularly advantageous oblique attachment, as stated above, an axial and central attachment of the handle handle is conceivable depending on the individual case (e.g. according to any existing handle handle labeling machine park) or in principle / remains executable so that the middle section of the handle handle is located directly above the container neck or a closure (corresponds to a handle handle angle of 90°, the so-called “overhead attachment”).

The handle handle angle of inclination in the angular range between 10 and 50 degrees, preferably between 30 and 40 degrees, even more preferably between 25 and 35 degrees, results from the above-mentioned [each defined between the axial axis (or vertical) and a longitudinal extension line of the handle handle]. The advantageous option for the user is that two molded containers according to the disclosure, in particular blow molded containers, can be carried with one hand at the same time. Here, the handle handles or handle handle middle sections are each enclosed by one of the user's hands. The (vertically/axially extending) lateral outer surface surfaces of two containers/canisters, in particular the molded container according to the disclosure, in particular blow molded containers, come into direct contact with one another, ie when gripped in pairs, and stabilize this carrying arrangement. The said preferred angular range creates physical forces or gravity vector components which press the canisters, in particular the molded containers according to the disclosure, in particular blow molded containers, against one another on said adjacent outer lateral surfaces. As a result, a molded composite of two canisters is advantageously further stabilized, for example against slipping and displacement.

Preferably, alternatively or cumulatively, the (first) thermoplastic of the molded container having the handle or of the bottom, torso and/or shoulder section and/or a respective associated same, similar or different material of the handle, in particular a second thermoplastic of the handle handle or include: polypropylene (PP), polyethylene (PE such as PE-HD; PE-LD), polyamide (PA), polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), in particular polyethylene terephthalate (PET); or a mixture/blend of the aforementioned types of thermoplastics. Optionally, the (first and/or second) thermoplastic can be partially or completely made of a recycled and/or recyclable material. Cumulatively or alternatively, the (first and/or second) thermoplastic may preferably comprise or consist essentially of a biodegradable material and/or mass, for example polylactic acid (PLA). Optionally, the (first and/or second) thermoplastic can contain an additive/auxiliary and the like, such as for achieving functional properties in blow molding production (e.g. demolding additive) and/or in product application (e.g. UV protection, nanosilver) and the like . Furthermore, the (first and/or second) thermoplastic can preferably be (quasi) free of a plasticizer. Optionally, it may be preferred that the (first and/or second) thermoplastic or the molded container according to the disclosure made therefrom, in particular blow molded container, and/or handle is/are transparent (colorless or colored) or opaque (colorless or colored). .

In this case (optionally; according to an aspect that may be subject to independent stress) the floor area [in particular outside of an (optional) floor trough can be used Stackability (and optionally for receiving an optional container neck on the shoulder section)] as a relief-like bottom contour surface with at least one axially retracted bottom recess molding segment and with bottom load contact molding segments adjacent to the bottom recess molding segment and projecting axially beyond this , so that the at least one bottom recess mold segment is excluded from a standing surface of the blow molding container. In particular, the at least one bottom recess molding segment for the stackability of the stackable blow molding containers can be shape-fitted or set up to be contactlessly spaced apart from a further shoulder section, which is the same as the shoulder section, by a gap dimension, so that only the bottom-load contact molding segments form a supporting load contact surface on the further shoulder section.

The last further aspect of the present disclosure, which may be claimed independently of the aforementioned aspect of the handle, is therefore to form a number of axial recesses on the (mold) container roof and a number of axial projections on the (mold) container bottom, which are thus on top of each other are coordinated so that when the (mold) containers are stacked on top of one another, the projections move into the recesses up to a stop in the recesses, so that between the (mold) container bottom of the upper (mold) container and the (mold) container roof a distance or a free gap remains in the lower (mold) container.

More specifically, the further (independent) aspect of the present disclosure is, in particular during the production of the container during (blow) molding or afterwards by further heating and deformation in the area of an end wall (container roof, shoulder section) forming/having a container spout Number (preferably plurality) of circumferentially spaced axial recesses/troughs, each of which form a load contact surface that is essentially plane-parallel or oblique to a container bottom and extends radially (and at least in sections in the circumferential direction). Furthermore, in particular during the production of the container, during (blow) molding or afterwards by repeating Heating and deforming in the area of the container base a number (preferably a plurality) of circumferentially spaced axial projections are formed, each of which forms a load support surface which is essentially plane-parallel to the load contact surfaces and which extends radially (and at least in sections in the circumferential direction), such that when two containers are stacked These only contact the load contact surfaces and the load support surfaces in the axial direction. This means that the troughs in the area of the container roof and the projections in the area of the container base are coordinated with one another in terms of their shape and dimensions so that when two containers of the above design are stacked on top of one another, they are only in the area formed by the troughs and projections (horizontal/perpendicular to the The load contact and load support surfaces extend axially on the axial axis of the mold container, whereas the axially projecting webs between the roof-side troughs and the axially receding indentations between the bottom-side projections essentially do not absorb any axial loads (i.e. are theoretically axially contactless).

The shoulder section can have an (optional) container neck (outlet) in its axial extension. In particular, the container neck can be closed or closed with an optional closure. In a front bottom surface of the bottom section, a (central) bottom trough can be axially retracted into the interior of the container. In this case, for the stackability of the stackable molded containers, in particular blow molded containers, (or when stacking them into a vertical stacking arrangement according to the second aspect of the disclosure below), the bottom trough can be shape-fitted or set up to contactlessly accommodate a further container neck similar to the container neck, in particular closed . The floor surface can be (radially) outside the floor trough as a relief-like floor contour surface, in particular concave, with at least one axially retracted floor recess shape segment (indentations) and, in particular convex, with adjacent to and above the floor recess shape segment axially projecting bottom load contact mold segments (projections), so that the at least one bottom recess mold segment is excluded from a standing surface (load support surface) of the mold container, in particular blow mold container. In other words, in particular, the at least one floor recess shape segment can be shortened in relation to the or all floor load contact shape segments with respect to the axial axis. In other words, the at least one bottom recess mold segment in particular (sub)divides the base area of the bottom surface of the mold container, in particular the blow mold container, which can now be formed (essentially only) by the bottom load contact mold segments.

Thus, the (optional) relief-like bottom contour surface (according to the further, possibly independent aspect) forms a three-dimensional shape structure directed towards the interior of the container, which offers the following functions and (application) technical advantages:

On the one hand, with regard to the removal of the (valuable) medical and/or pharmaceutical (particularly liquid) preparation when it is used as intended from a particularly upright molded container, in particular a blow molded container, a residual amount that can no longer be removed is advantageously reduced. In other words, the proportion of lumens that can be filled in the vicinity of the floor area (last accessible from, for example, a suction hose of a dialysis machine, etc. for removing the preparation) is in favor of the volumes which are created by the floor trough and by the at least one floor, which is also retracted into the interior of the container -Recessed form segment is taken, advantageously reduced.

On the other hand, the (optional) relief-like floor contour surface (according to the further, possibly independent aspect) in connection with the floor trough (specific “dome geometry”) advantageously ensures or improves vertical stackability. In this respect, a positive connection results when stacking the molded containers according to the disclosure, in particular blow molded containers. As a result, the prohibitive slipping of stacked containers, particularly in the pharmaceutical/medical sector, is effectively prevented.

Furthermore, as explained further below, the bottom recess shape segment can be used as a (optionally asymmetrical or symmetrical) Recess to accommodate an optional dimensionally stable shaped handle, ie a separately manufactured, solid handle element, be set up and thus serve.

Preferably, alternatively or cumulatively, the at least one bottom depression mold segment can be shape-fitted or set up for the stackability of the stackable molded containers, in particular blow molded containers, (or when stacking into a vertical stacking arrangement according to the second aspect of the disclosure below). the further shoulder section (container roof), which is similar to the shoulder section, is spaced apart without contact by a gap dimension, so that only the floor-load contact form segments on the further shoulder section (container roof) form a load-bearing load contact surface. Preferably, the mold container with the handle handle can be designed for vertical stackability and can be set up so that a gap formed between two identical mold containers when stacked vertically with the gap dimension is sufficiently dimensioned to accommodate the handle handle middle section. The handle can be designed to be particularly flexible. The handle handle can be set up in particular, in particular designed to be flexible, in order to nestle and/or curl into the intermediate space. This advantageously ensures that the handle does not protrude or protrude from the mold container, which means that the horizontal stackability is not (sterically) impaired.

Optionally, the gap size (particularly minimal along an axial extent) can be between preferably approximately 0.05 to 20 millimeters, more preferably between approximately 0.5 to 10 millimeters, in particular between approximately 0.5 to 8 millimeters.

Accordingly, the load contact surface on the bottom side is not divided/subdivided into the individual, protruding (convex) floor load contact shape segments.

Preferably, alternatively or cumulatively, the at least one bottom depression mold segment may extend (at least partially) radially. In particular, the at least one bottom recess shape segment can differ from one opening-side first floor trough diameter of the floor trough in the transition of the floor surface and / or extend to an outer circumference of the floor surface.

Preferably, alternatively or cumulatively, the container neck can be arranged in a shoulder inner region of the shoulder section which is radially inner around the axial axis, in particular centrally/in the axial axis or central longitudinal axis.

Preferably, alternatively or cumulatively, the shoulder section outside the container neck can be shaped convexly in relief with at least one shoulder elevation shape segment (web) between adjacent shoulder load contact shape segments. This initially serves to improve the overall rigidity of the molded container, in particular the blow molded body container, as well as a further reduction in the remaining amount of preparation that can be removed when it is used as intended. In this case, the at least one shoulder elevation mold segment (web) can be shape-fitted or set up for the stackability of the stackable molded containers, in particular blow molded containers (or when stacking to form a vertical stacking arrangement according to the second aspect of the disclosure below). Stacking) in each case complementary to (or with respect to) the further bottom recess mold segment, which is the same as at least one bottom recess mold segment, to be opposite (this) at a contactless distance, so that the load contact surface is divided on the shoulder side between the shoulder load contact mold segments . This advantageously serves for optimization in terms of statics and strength theory aspects and improves/expands the (vertical) stackability even further with a view to being able to safely stack more than two, i.e. multiple stacking layers of the molded containers, in particular blow molded containers.

Preferably, alternatively or cumulatively, the load contact surface (load contact surface) on the shoulder side in the shoulder load contact form segments (troughs) can be formed flat in a cross-sectional plane of the shoulder section perpendicular to the axial axis. In other words, the shoulder load contact mold segments can be used to stack the stackable mold containers, in particular blow mold containers (or when stacking them vertically Stacking arrangement according to the second aspect of the disclosure below) can be shaped or set up to form a flat standing surface (the shoulder load contact shape segments taken together, so to speak) or to span a standing plane. In other words, this means that another / identical (upper) mold container, in particular a blow mold container, which is stacked vertically on the (first / lower) mold container, in particular a blow mold container, can advantageously stand on the latter in a similarly stable manner as on a floor level when placed directly on it, i.e. without stacking.

Preferably, alternatively or cumulatively, the at least one shoulder elevation mold segment can be shape-fitted or set up for the stackability of the stackable molded containers, in particular blow molded containers, (or when stacked to form a vertical stacking arrangement according to the second aspect of the disclosure below) in order to ( during stacking) to engage in a form-fitting manner in the further at least one bottom recess mold segment which is the same as the at least one bottom recess mold segment. In particular, the at least one shoulder elevation mold segment can be set up to prevent relative rotation of the stacked mold containers, in particular blow mold containers, (against each other) about the axial axis. In other words, these special three-dimensional shapes or mold structures in the shoulder section and in the bottom section of the mold container, in particular blow mold containers, which are at least partially / substantially complementary to one another / interlocking / mechanically interact in a mold composite, bring about a positive connection. In this respect, this provides additional stabilization by significantly counteracting or even preventing twisting of the mold assembly.

In other words (according to the further, possibly independently claimed aspect; optional) on the one hand there is an end-side shoulder surface of the shoulder section (in the case of vertical stacking: a first/lower mold container, in particular a blow mold container), which has a shoulder-side three-dimensional mold structure in the form of at least one shoulder -Elevation shape segment [optional or in a preferred embodiment, with reference to the accompanying Figures 1 to 7: of four shoulder elevation mold segments arranged in a cross shape around the container neck, each with a radial extension] and the shoulder load contact mold segments adjacent to this/these [optionally or in the preferred embodiment: of four shoulder elevation mold segments , which are respectively provided or formed on the four shoulder-side corner edges of a substantially cuboid molding container, in particular a blow molding container, with respect to the body section] (relief-like), and on the other hand a front bottom surface of the bottom section (in the case of vertical stacking: a second / the first identical / upper mold container, in particular blow mold container), which has a three-dimensional mold structure in the form of the at least one bottom recess mold segment [optionally or in the preferred embodiment: four bottom recess mold segments, each between two of the four bottom corner edges of the (quasi) cuboid mold container, in particular blow mold container, are provided or shaped to stand together (viewed) in a cross-shaped arrangement] and the floor load contact mold segments adjacent to this/these [optionally or in the preferred embodiment: of four Floor load contact mold segments, which are respectively provided or formed on the four bottom sides of the (quasi) cuboid molding container, in particular blow molding container] (relief-like), shaped or set up to fit one another in order to form a positive connection in the axial direction to one another cause.

This positive connection (according to the further aspect, which may be claimed independently) advantageously serves to remove or block a degree of freedom of rotation about the axial axis or about a longitudinal central axis of the molding container, in particular the blow molding container. In other words, the shoulder-side (three-dimensional) mold surface contour or the entirety of the shoulder-side mold structure elements (in an axial direction away from the center of the mold container, in particular blow mold container) and the bottom-side (three-dimensional) mold surface contour or the entirety of the bottom-side mold structure elements (in an axial direction away from the center of the further/similar molding container, in particular blow molding container) [or. vice versa] form a key-lock-like or plug-in system-like form fit. In particular the axial Distance fit is shaped or set up in such a way that the load contact surface does not fall into the area of the at least one bottom recess shape segment or complementary shoulder elevation shape segment. This has the advantage that the load/weight (load) is transferred to the peripheral outer surface of the fuselage section, ie to support structures provided materially in the sense of a wall thickness and not to inner cavity areas [esp. like a supporting pillar on the optional four corners or corner edges].

In this context, with regard to the second aspect of the above disclosure disclosed below with regard to a vertical stacking arrangement, it should be noted as a precautionary measure that the person skilled in the art understands that the information disclosed with regard to the first aspect of the molded container according to the disclosure, in particular the blow molded container, and a mold fit (according to the further, if necessary Features relating to the aspect (which are to be claimed independently) can be proven individually or on their own. In this respect, these claimed features can be either virtual (e.g. based on a construction drawing, a CAD 3D model) or real (e.g. based on cutting the mold container, in particular the blow mold body Z container, along a cutting plane falling into the fuselage section and axially swapped assembly the bottom half onto/into the shoulder half).

Preferably, alternatively or cumulatively, the bottom section can be formed in a polyhedral shape with an associated plurality of corners in a cross-sectional plane perpendicular to the axial axis. Some or all of the corners can have the floor load contact shape segments, in particular in proportion to the uniform and/or symmetrical load distribution. This advantageously serves to ensure balanced statics/rigidity of the molded container, in particular the blow molded body container, as well as overall positive storage/handling properties.

Preferably, alternatively or cumulatively, the bottom section can be rectangular with four corners in a cross-sectional plane perpendicular to the axial axis. Some, in particular all, of the four corners can have the floor-load contact form segments. In particular, four optional shoulder straps can be used Elevation shape segments can be arranged in a cross shape around the container neck and each radially to it, in particular opening into it (with a continuously tapering contour line) [cf. the preferred embodiment explained above, with reference to the accompanying Figures 1 to 7], In other words, the described cross-shaped or “cross-shaped” arrangement of the described mold structure elements advantageously results in a specially shaped, novel contact surface of two (same) mold containers according to the disclosure (according to the further aspect, which may be claimed independently). In this respect, when stacked vertically, these only touch each other at the outer (particularly stable) four corners, i.e. in the shoulder section (shoulder load contact mold segment) of the lower mold container, in particular the lower blow mold container, or in the bottom section (bottom load contact mold segment) of the upper mold container , especially the upper blow molding container.

Preferably, alternatively or cumulatively, the bottom section and/or the shoulder section (essentially, viewed from a bottom view or top view) can be shaped mirror-symmetrically, in particular point-symmetrically. The mirror axes can include, in particular, the diametrical lines/cutting planes.

Preferably, alternatively or cumulatively (according to the further aspect, which may be claimed independently), there can be on the load contact surface within at least one of the base load contact mold segments on the base side a base mold structure element which is concave in the direction of the axial axis or contoured towards the interior of the container, in particular ( at least partially) radially, in particular in the form of a radial groove; and on the shoulder side, a shoulder shaped structural element which is contoured vice versa/complementary to the base shaped structural element, ie correspondingly convex, can be formed, in particular (at least partially) radially, in particular in the form of a radial longitudinal curvature. In particular, a radial shape or a radial course can have a substantially radial shape from bzz. forming a formation of bottom and complementary/corresponding shoulder mold structural elements extending from the central axial axis of the mold container. Preferably, alternatively or cumulatively, the ground and complementary associated/corresponding shoulder Molded structural elements run radially from the base trough. The form fit described above serves as an additional lock against rotation and further increases the stability of the vertical stacking arrangement against uneven weight distribution, slipping, tipping or overturning. In particular, in each case/per corner side, the at least one, in particular pair, of the (at least partially radial) bottom shaped structural elements can be fitted to (or shape-fitted to) the at least one, in particular pair, of the (at least partially) radial shoulder shaped structural elements.

In other words, in the sense of improved stability of a vertical stacking arrangement, the (at least partially radial) bottom shaped structural elements (from above) fit/press/'latch' into the appropriate radial (at least partially radial) shoulder shaped structural elements (below), so to speak to rest against each other in a form-fitting manner. This advantageously causes a (vertical) locking and thus further securing of a tower-like stacking arrangement against slipping, twisting, twisting, tipping, etc. of the (blow) molded containers. In other words, the aspect described above further advantageously increases the balance and stability of the (vertical) stacking arrangement. As a result, operational safety in the clinical process for a medical user is significantly increased and the risk of accidents is reduced. This also reduces the risk of potential storage and/or transport damage to the molded containers according to the disclosure filled with the valuable medical and/or pharmaceutical preparation.

Furthermore, there is a further advantage of the above feature (according to the further aspect, which may be claimed independently) with regard to the thermoplastic molding process, in particular blow molding process, for producing the molded container according to the disclosure, in particular blow molded container. In this respect, there are also production-technical advantages due to the (at least partially) radial course, which arise from the point of view of good demoldability from a molding tool. The molding tool can thus have individual molding tool stamps in the area of the base section or shoulder section for easy demoulding or ejection of the finished molding containers. The individual mold dies can be moved along be separated by a radial line corresponding to the (at least partially radial) base mold structure elements or shoulder mold structure elements. For example, the individual mold stamps can represent circular angle segments. In this way, the individual mold stamps can move separately with a radial movement component (ie superimposed on an axial movement component) for demolding or ejection, advantageously easily and thus with a high cycle rate. In contrast, mold structures with a tangential and/or annular course of a body edge, which are not open, cup-shaped, dome-shaped like the bottom trough, but are, for example, groove-shaped, have technical problems with regard to gluing, shrinking, etc. on the mold. As a hindrance to production, these can lead to frequent molding machine downtimes or a high proportion of rejects.

Preferably, alternatively (or vice versa to the above feature) or cumulatively, a floor shaped structural element (e.g. longitudinal curvature) which is convexly contoured in the direction of the axial axis can be formed on the load contact surface within at least one of the floor load contact shape segments on the bottom side; and on the shoulder side, a contoured shoulder shaped structural element (e.g. groove, longitudinal groove) can be formed vice versa/complementary to the base shaped structural element, i.e. correspondingly concave. In particular, the shoulder mold structure element can be shape-fitted or set up for stackability (or when stacking to form a vertical stacking arrangement according to the second aspect of the disclosure below) of the stackable molded containers, in particular blow molded containers, to (during stacking) on a further, The base mold structure element which is similar to the base mold structure element lies in a form-fitting manner (or in order to rest in a form-fitting manner during stacking on the associated base form structure element and the mold container, in particular the blow mold container).

Preferably, alternatively or cumulatively, the (optional) bottom trough can be, preferably cup-shaped, in the direction of the interior of the container from the opening-side first bottom trough diameter to a base-side second bottom trough diameter of the inner bottom trough base via a Taper the depth of the soil depression. In this case, the floor trough can in particular have at least one floor trough step on a step-like narrowed third (or additional) floor trough diameter. This advantageously serves to stiffen the floor trough. Furthermore, both the taper and the (optional) bottom trough shoulder mean that the remaining amount of the (valuable) medical and/or pharmaceutical (especially liquid) preparation that can no longer be removed from the molding container, in particular blow molding container, is advantageously further reduced. The person skilled in the art understands that the specific three-dimensional contour or shape structure of the floor trough, as exemplified by the preferred embodiments shown in the figures, is not essential to the disclosure, but that equally equivalent contours or shape structures are conceivable. For example, the bottom trough can be rectangular, pyramid-shaped, etc. Nevertheless, it can be seen that with regard to the overall dimensional stability / mechanical properties / load statics there are interactions, possibly a synergistic interaction or optimal areas, according to the design / shape of the floor trough and the design / shape of the adjacent, especially surrounding, relief-like floor contour surface.

Preferably, alternatively or cumulatively, the molding container, in particular blow molding container, which has/defines a radial first wall thickness in the base section, a radial second wall thickness in the body section and a radial third wall thickness in the shoulder section, can be formed from a thermoplastic material/material in this way be that the first, second and / or third wall thickness: (a) is at most approximately 1.5 millimeters, more preferably between 0.05 and 1.2 millimeters, in particular between 0.15 and 1.0 millimeters, or be; and/or (b) has or have a relative spread around their respective mean value of at most +/- 150%, in particular at most +/- 50%; and/or (c) has or have a relative spread around its overall mean value calculated from the first, second and third wall thicknesses of at most +/- 150%, in particular at most +/- 50%.

Optionally, the molded container, in particular blow molded container, can consist of a preform (optionally having the finished container neck) with a opposite first, second and / or third wall thickness thicker fourth wall thickness be bias formed.

Preferably, alternatively or cumulatively, the thermoplastic material can be suitable for direct absorption and subsequent storage of the medical and/or pharmaceutical preparation at the manufacturing side, in particular be (long-term) inert to the preparation, more preferably additionally selected or modified in order to specifically to bring about optimal flow behavior in the thermoplastic state to form the aforementioned features with regard to the wall thickness (distribution) for the molded container according to the disclosure, in particular blow molded container. As a result, material consumption and long-term mechanical stability/statics required for the product are optimized as mutually opposing influencing factors.

Preferably, alternatively or cumulatively, the molding container, in particular blow molding container, can have at least one rib or rib (mold) structure running around the body section, at least in sections, in particular substantially transversely to the axial axis (i.e. quasi 'horizontal'), in particular have a plurality or formation of ribs which preferably run at least partially parallel to one another. In this case, the at least one rib or formation/row of ribs can optionally be provided with one, in particular per at least one (especially on all of the) respective side surfaces/lateral surfaces of the fuselage section (i.e. seen from a side view of the (blown) molded body/container). , V-shaped course or be formed. In this case, the apex of the V-shape, particularly in the middle, can either point towards the shoulder section (i.e. upwards) or in the manner of an inverted (i.e. upside-down V-shape) towards the bottom section. The person skilled in the art understands that modified shapes are conceivable, for example a double V shape, a combination of a first row of the V shape above or below a second row of the inverted V shape, wavy shapes, etc.

The at least one optional (stiffening) rib (or plurality or formation of ribs) is between a pair of adjacent ones Depressions/ribbed grooves/grooves formed. The rib or recess/rib groove advantageously serves to stiffen/optimize the static load-bearing properties as well as to improve the manual handling properties, especially with regard to the filled (blow) mold container. In other words, the rib acts as a hull structural element. This rib (form) structure therefore advantageously increases the stability after filling the (blown) molded container with the preparation. As a result, any deformation/bulging of the (blown) molded body Z container is counteracted, which ensures or improves its dimensional stability, especially with regard to the desired vertical stackability, storage stability under the prevailing conditions such as temperature, mechanical stresses caused by transport and the like. In particular, the (optional, ie fundamentally dispensable if the wall thickness is sufficient) ribs prove to be particularly advantageous in the context of ideally reduced wall thicknesses, insofar as one wants to further reduce the use of the thermoplastic for the (blown) molded body Z container. The rib (form) structure is particularly useful when stacking the mold containers vertically

Blow molding containers with several (i.e. more than two) layers are important insofar as the resulting, correspondingly multiplied, support Z weight forces can be absorbed and distributed better (down to the lowest layer).

The rib is formed as a substantially uniform, (preferably continuously) circumferential, in particular (substantially or with respect to a primary direction of extension) transverse to the axial axis (ie horizontally), elevation or convex bulge relative to the adjacent depressionsZ rib grooves. For example, the rib can have a (particularly respective) rib cross section that is plateau-shaped, prism-shaped, rectangular or round, rounded, ovalized or designed according to a free contour. Optionally, some or all of the (especially otherwise circumferential) ribs and Z or the depressions Z rib groove can be interrupted by flat areas, for example around a for a label (e) and Z or an attachment of a film strip-shaped handle (according to an aspect that may be claimed independently) andZor to provide a flat surface intended for manual or robotic gripping. Optionally or alternatively, a wall thickness in the area of the rib and Z or the Depression/groove differs from another (first, second and/or third) wall thickness of the molding container, in particular blow molding container, possibly significantly, for example greater than 10% relative deviation. The person skilled in the art understands that it can optionally make sense to determine the wall thickness(es) in the area of the rib and/or the recess/rib groove as separate size(s) or to adjust them in the blow molding (manufacturing) process. Alternatively, it may be desirable or advantageous for the wall thickness(es) in the area of the rib and/or the recess/rib groove to be essentially uniform to the other (first, second and/or third) wall thickness of the molding container, in particular the blow molding container Size(s) to be determined or uniformly adjusted to the other wall thickness(es) in the (blow) molding (manufacturing) process.

Preferably, alternatively or cumulatively, the molded container, in particular blow molded container, can have at least one label (in particular a label, a self-adhesive film label surface and the like) on at least one lateral surface section and/or on a (visible) side surface, in particular on the body section. be provided. The label can optionally be applied to the rib-shaped structure, with an adhesive intended for labeling preferably leaving out the rib grooves. The label serves the (legally required) product identification and user information in a technically simple manner.

Preferably, alternatively or cumulatively, the molded container, in particular a blow molded container, is closed with a closure, in particular a screw (lid) closure (with an internal thread). This advantageously serves to close the (blow) molded container filled with the preparation in a simple manner in terms of production technology. The closure (particularly manufactured separately, for example by injection molding and available for delivery) can be easily modified in terms of production technology and equipped with specific functions. For example, the closure can optionally include additional elements such as a hinged opening and/or a piercing membrane. This advantageously serves for a convenient and/or (largely) sterile removal of the preparation. Preferably, alternatively or cumulatively (according to an aspect that may be claimed independently), a dimensionally stable molded handle can be attached to the container neck. In particular, the (dimensionally stable) can be made, in particular injection molded, from a thermoplastic material (optionally different from or similar/modified, for example with regard to the so-called melt flow index, or the same as the thermoplastic of the molded container, in particular blow molded container). In particular, the shaped handle can be attached firmly, in particular in a non-detachable manner, to the container neck, for example attached/fixed by shrink-fitting or by means of a cap device. In particular, the molded handle can have a proximal molded handle ring section (with respect to the container neck or the molded container, in particular blow molded container) in order to be attached (in particular non-detachably) to the container neck by means of this. The shaped handle ring section can (optionally) be designed on the inside with barb-shaped elements. The barb-shaped elements are designed to fix the shaped handle on the container neck in a rotationally secure manner. This advantageously prevents detachment during manual carrying.

Furthermore, the mold handle has (at its opposite end) a distal mold handle holding portion of the mold handle) which extends (starting from the mold handle ring portion) substantially radially from (away from) the container neck. In particular, the shape handle holding section can be formed in a T-shape or U-shape. Accordingly, the shaped handle can also be referred to as a T-handle or U-handle. By (optionally) providing a handle element such as the molded handle (and/or the handle handle described below, according to an aspect that may be claimed independently) made of a separate carrier material, flexibility in handling or using the (blow) molded container according to the disclosure can be further improved. Furthermore, production is simplified by prefabrication of the separate handle element. In this respect, it can be advantageous from a production perspective (in terms of investment savings and so-called “economies of scale”) on a case-by-case basis, but not in a limiting sense, to purchase a separate handle element as a purchased part from a supplier that specializes in handles. In this case, the at least one bottom recess molding segment can be shape-fitted or set up for the stackability of the stackable molded containers, in particular blow molded containers, (or when stacking to form a vertical stacking arrangement according to the second aspect of the disclosure below) from the further, the shoulder section equal, shoulder section, to be spaced contactlessly at least by a minimum gap dimension. In particular, the minimum gap dimension can exceed a maximum axial shape grip external dimension of the distal shape grip holding section. This advantageously serves to accommodate the mold handle without negatively influencing or even disrupting the other (vertical) stacking properties.

A second (possibly to be claimed independently) aspect of the present disclosure relates to a (in particular vertical) stacking arrangement or a stacking system of at least two, preferably at least three, in particular at least four, (in particular vertically or along the axial axis) stacked (same and/or substantially similar) molded containers according to the disclosure, in particular blow molded containers. In particular, a (combined) stacking arrangement can be provided stacked in both the vertical and horizontal directions. This serves in particular to ensure optimal use of space in the area of storage and transport. Insofar as the stacking arrangement/stacking system comprises the (same and/or essentially similar) molded containers according to the disclosure, in particular blow molded containers, in the form of a module/component, it should be expressly pointed out that identical features and advantages arise as for the first aspect of the present disclosure .

Preferably, the external dimensions of the (blow) molding container, in particular the fuselage section, can be designed such that (particularly with regard to a vertical repeat component) multiple units of the blow molding container form a positive (stacking) composite on a transport pallet (in particular EU Transport pallet, standardized sea freight/container pallet) result (in particular no protrusion of the molded containers, especially blow molded containers). This has the advantage that no or only minimally reduced free space, for example a transport container volume, is unused remains. In other words, this ensures optimal utilization of the available floor space on a standard transport pallet. In particular, the following dimensions of the mold container, in particular blow mold container, may be preferred, for example with a nominal filling volume of approximately 4.7 to 4.8 liters: a) 148 mm x 158 x 295 mm (mold container width x mold container depth x mold container -height) for the EU transport pallet; or: b) 140 mm x 150 x 320 mm (mold container width x mold container depth x mold container height) for the standardized sea freight/container pallet. However, the aforementioned filling volume of approx. 4.8 liters should not be seen as limiting; Further, increased or reduced filling volumes are also claimed or possible within the scope of the present disclosure, in particular those that result from an adaptation of application profiles of the medical/pharmaceutical preparation.

Further reductions in the filling volume would also be conceivable, particularly following current trends, more preferably to approximately 3.8 to approximately 4.2 liters. In this respect, further advantages arise, particularly against the background of an improvement in the environmental balance, reduced manufacturing costs and/or due to an adjustment of the filling volume for shorter dialysis times and/or lower dialysate flow rates. To implement the above optimization tasks with regard to an optimal packing format on a transport pallet, the following dimensions (mold container width x mold container depth x Mold container height) may be preferred: a) mold container with a filling volume of approximately 3.8 liters: 148 mm x 158 mm x 243 mm; or b) molded container with a filling volume of approx. 4.2 liters: 148 mm x 158 mm x 261 mm.

Alternatively or cumulatively, multiple filling volumes are proposed in order to allow double or multiple use in relation to a (e.g. clinically usual or commercially available) consumption unit of the medical/pharmaceutical preparation, in particular a dialysis preparation Z solution (such as approx. 7.6 to 8.4, or approx. 9.4 to 9.6 or 10.0 liter content, etc.). Alternatively, the molded container, in particular a blow molded body container, can be packed ex works in a cardboard box or other secondary packaging. In this respect, the advantage of vertical stackability would not occur during the transport itself, but nevertheless in the course of the intended use of the preparation and/or in the course of the preparation of the latter, for example in a clinical process/material flow. For example, additional storage space is advantageously created, which saves corresponding storage capacity.

In particular, the dimensions/dimensions/form fits of the mold container, in particular the blow mold container, can be optimized and designed in terms of application technology in such a way that the following influencing variables or technical aspects, in particular, are taken into account, cumulatively or alternatively. In particular (but not limiting) all of the influencing variables can be combined in a particularly preferred embodiment (see figures) and implemented in a particularly advantageous manner:

- nominal filling volume corresponding to the usual contents of the medical/pharmaceutical preparation for its intended use (e.g. dialysis liquid or solid concentrate for carrying out a dialysis treatment);

- Vertical stackability for transport, storage, etc.;

- in particular the possibility of additional stabilization when setting up/connecting to a device/machine unit intended/operable for the intended use of the medical/pharmaceutical preparation (e.g. a dialysis machine);

- in particular connection option to the dimensions/dimensioning of the removal suction device of the device/machine unit (e.g. the dialysis machine);

- dimensions/dimensions of the floor section with regard to a designated storage area for the device/machine unit (e.g. a floor plate of the dialysis machine); - Bottom trough (“dome geometry”) to minimize the amount of medical/pharmaceutical preparation remaining in the container after completion of a treatment (e.g. dialysis treatment).

A third (possibly to be claimed independently) aspect of the present disclosure relates to a method for producing the molded container according to the disclosure, in particular a blow molded container, according to the first aspect, comprising the steps:

- Thermoplastic formation or molding, preferably injection molding, in particular blow molding, of a thermoplastic material, preferably PET, which is suitable and/or inert with regard to the medical and/or pharmaceutical preparation, in its thermoplastic flow state within a divisible, complementary to the mold container designed and set up Molding tool, in particular (in the case of the blow molding process) the thermoplastic, preferably PET, can be presented in the form of a preform with the container neck finished;

- Cooling of the thermoplastically designed or shaped mold container for removal / shaping in its solidified state (in particular sufficiently dimensionally stable); and

- immediately subsequent or separately subsequent attachment, in particular gluing and/or attachment, of the handle handle to the thermoplastically formed or shaped molded container.

The handle can be (provided) as a finished (ie cut to length) intermediate product. For example, the handle can be provided as a purchased part. Alternatively or cumulatively, the handle handle can, for example, in advance of its attachment, in particular in spatial proximity to the removal of the thermoplastically formed or shaped molding container from the molding tool and / or an intermediate storage or a buffer station, from a film roll, tape roll or the like to a predetermined one Handle handle length and/or a nominal length of the handle handle can be cut to length. The person skilled in the art understands that the (film) material of the handle can be produced in all conventional processes of (multi-layer) (packaging) film production, such as: Blown film production, calendering, extrusion film production, laminating, Langmuir-Blodgett, thin film process, etc.

An optional step, which in particular can be at least partially superimposed on at least one of the above steps, concerns filling the molding container, in particular the blow molding container, with the medical and/or pharmaceutical preparation. A further optional step relates to closing the filled mold container, in particular blow mold container, preferably in the mold, in particular blow mold, or in a molding machine, in particular blow molding machine, which operates the mold, in particular blow mold. In this respect, the handle can be attached to the thermoplastically formed or shaped and (optionally) filled and/or (optionally) closed molded container immediately afterwards or separately.

Blow molding refers to a process for producing hollow bodies from thermoplastics, in particular an injection, drawing and blowing process. Blow molding can be based on extrusion blow molding and/or stretch blow molding. During blow molding, a quantity or volume or mass unit of a thermoplastic material, in particular in the form of a preform (optionally prefabricated separately as an intermediate product), is introduced and brought into its thermoplastic flow state (by means of heating and/or extrusion kneading). This is then subjected to internal pressure via a blow nozzle of the blow molding machine and is thereby pressed against the mold contours of a blow molding tool in order to assume the desired molded body shape. The use of separately movable blow mold dies to achieve complex mold structures with, for example, undercuts is known. Furthermore, the blow molding process can optionally be implemented as a so-called blow-fill-seal process (ie including filling and closing in the container neck area while still in the blow molding tool) and/or as a so-called hot-fill process. Patent document US 5,411,699, which is hereby expressly incorporated by reference into this publication, discloses one in one Blow molding process operated by a blow molding machine for thermoplastic blow molding or production of blow molded (hollow) bodies such as PET beverage bottles, wherein a separately prefabricated (injection molded), approximately test tube-shaped preform with an external thread integrally formed at an opening is inserted into a divisible blow mold and in the thermoplastic State to which the blow mold (hollow) body is blow molded. The container neck preferably retains its original dimension and shape, ie of the preform, is therefore not changed during stretch blow molding. Furthermore, a subsequent hot filling step is disclosed.

Blow molding as the (preferred) thermoplastic process for producing the molded container according to the disclosure, in particular blow molded body container, for the medical/pharmaceutical preparation based on a thermoplastic/material (in particular, but not limiting, polyethylene terephthalate/PET). generally has the advantage of increased cycle times compared to the previous injection molding process.

At the same time, blow molding has the additional advantage of reduced material costs due to the significantly reducible wall thicknesses (no need for the flow channel flow resistance that limits the minimum wall thickness in the injection molding process), which overall leads to a significant reduction in production costs and a lower environmental impact. In particular, in the thermoplastic formation or molding according to the disclosure, in particular blow molding, the average and / or nominal wall thickness can be in the range of at most approximately 1.5 millimeters, more preferably between 0.05 and 1.2 millimeters, in particular between 0.15 and 1.0 millimeters.

In contrast, it is known that in large-scale (standard) injection molding processes, usual wall thicknesses of conventional mold containers range from approximately 0.5 mm to 0.8 mm up to approximately 3 mm and more. Furthermore, the prior art for large-scale (standard) injection molding processes describes that, for example, a flow path to wall thickness ratio of up to 60 can be achieved. In other words, injection molding processes are more suitable for producing robust (filled) components such as a car bumper or a transport pallet, less so for the production of hollow (unfilled) components such as (especially thin-walled) containers.

However, if necessary or in some cases, thinner wall thicknesses, i.e. in the range of less than approx. 0.5 mm up to approx. 0.3 mm, can be achieved using special injection molding processes (which may be technically more complex and therefore more cost-intensive). In particular, such special injection molding processes for achieving said thinner wall thicknesses relate to the so-called thin-wall injection molding (in particular based on specific mold coatings and/or on specific grades of the thermoplastic/material optimized with regard to the solidification rheology) and/or the so-called high-pressure Injection molding (for example in the range of an injection pressure above 1,000 bar, in particular above 2,000 bar and more).

In other words, it is preferred to design/shape the molded container according to the disclosure as a blow molded container or by means of blow molding, but this should not be construed as limiting. In this respect, it is conceivable that when weighing up all aspects for a product design (such as long-term storage stability and/or high transport robustness of the molded container as primary packaging and/or application technology) and/or for the start of production (such as, for example, with regard to investments to be kept low). a machine park historically available at a production site, etc.) if necessary, the injection molding process (standard or special injection molding) is selected.

The thermoplastic formation or molding, preferably injection molding, in particular blow molding, also has the advantage that the molded container according to the disclosure, in particular blow molded body Z container, can assume its specific, three-dimensionally complex shapes/shapes in a manufacturing-technically efficient manner, such as the essential specific one in the present case Bottom geometry (in the form of a “dome geometry” directed into the interior of the container) as well as the optional lateral rib (form) structure for stiffening. Basically suitable for the above-described (thermoplastic shaping) process for producing the molded container according to the disclosure, in particular The blow mold body container for the medical/pharmaceutical preparation is the thermoplastic plastic/material if the disclosed characteristic features and suitability can be achieved in the course of the corresponding (thermoplastic shaping) process.

In the case of the thermoplastic material such as polyethylene terephthalate (PET), the advantage in the preferred embodiment of the blow molded body Z container or the blow molding process is that the thermoplastic starting material is not extruded in the form of pellets up to the blow nozzle, but in the form of preforms Z Blanks Z pre-molded bodies can be prefabricated in order to then obtain their final dimensions and shapes of the (blown) molded body Z container according to the disclosure at the actual production and filling location, for example by means of stretch blow molding. For example, a preferred PET preform with a volume of 220 ml can hold a nominal filling volume of the (blow) molding container of 4.7 liters after blow molding. This corresponds to a more than 10-fold compression of cargo space for the transport of the starting materials to the place of production or filling with a medical/pharmaceutical preparation, especially liquid. This advantageously supports a resource-optimized manufacturing process and an optimized supply chain with, last but not least, a reduced carbon footprint. However, the molded container can also be produced in a direct one-step (thermoplastic) production process. The mold container can be converted directly into its final shape, starting with granules or pellets and Z or a similar thermoplastic material. In other words, the intermediate step in the production of an above-mentioned pre-molded body (such as a PET preform) can be omitted.

A fourth (possibly to be claimed independently) aspect of the present disclosure relates to a use of the molded container according to the disclosure, in particular blow molded container, according to the first aspect and Z or the stacking arrangement according to the second aspect of the present disclosure for receiving and Z or for transport and Z or for storing the medical and Z or pharmaceutical preparation and Z or for technical application provision the preparation, especially in a dialysis machine. In particular, a machine receiving mold structural element of a logistically used device (e.g. automated warehousing) can be partially or completely complementary in shape to the bottom surface of the molding container, in particular the blow molding container (ie according to the shape of the bottom trough and/or the shape of the adjacent relief-like bottom contour surface). ) and/or a medically/clinically used device (e.g. a dialysis machine). This advantageously serves to ensure an optimal, non-slip positioning of the molded container, in particular the blow molded body Z container, when the preparation is used as intended.

Preferably, alternatively or cumulatively, the medical and/or pharmaceutical preparation can be in the form of a liquid or solid (e.g. powdery, granular), in particular concentrated with regard to at least one active ingredient or protagonist, preparation, in particular dialysis preparation.

In summary, the present disclosure provides an innovative storage/transport container for medical/pharmaceutical liquids or solid concentrates, which is suitable for use in the medical/pharmaceutical sector, in particular for the Use in chronic hemodialysis/diafiltration is optimized. The following are significant advantages: Reduction of the necessary raw materials/basic materials (first and/or second thermoplastic); (vertical) stackability without slipping, tipping or twisting; optimal (horizontal) utilization of the standing space on transport pallets; good positioning for connection to a terminal device/peripheral device in connection with the intended use of the preparation contained (liquid/solid concentrate); Usability or optional use of the, in particular flexible, handle, to improve carrying comfort (wide variation in the anatomical diversity or hand size Z shapes of the user) and for (optional) attachment of the molded container, in particular blow molded container, to the terminal/peripheral device. Through optimized use of resources (in particular a greatly reduced use of the first and/or second thermoplastic; Furthermore, due to the logistic optimization described), the environmental balance is significantly improved based on the molded containers according to the disclosure, in particular blow molded containers.

Detailed description of preferred embodiments

Preferred embodiments of the present disclosure are described in more detail below based on the associated figures. First embodiment

Figures 1 to 5 show a blow molded body or (blow) molded container 100 as a molded container according to the disclosure, in particular a blow molded container, according to a first preferred embodiment, set up (or prepared as an intermediate product) for attaching a handle handle 113 according to the disclosure (not shown, see figures 9 and 10). The unfilled (blown) molded body Z container 100, which can be filled (from above) via an (optional) open container neck 70, is designed to hold a medical and/or pharmaceutical preparation (not shown; with reference number 2, see FIG. 9 with regard to a filled one End product based on the (blown) molded body Z container 100). For this purpose, the (blown) molded body Z container 100 is made from a thermoplastic material suitable for filling with and storing the medical and/or pharmaceutical preparation, in particular an inert thermoplastic material. In other words, the (blown) molded body Z container is formed or shaped (three-dimensionally) in a thermoplastic manufacturing process or shaping process. In particular, the (blown) molded body Z container 100 can be in a technical thermoplastic grade/type, in particular in a blow molding grade/type (i.e. according to a so-called melt flow index that can be used in a thermoplastic molding machine, especially a blow molding machine), esp . made of PET, (blow) molded.

With reference in particular to the side views of Figures 1 and 2c, the (blown) molded body Z-container 100 has a bottom section 20 with an end-side bottom surface 11 at one end of a body section 50. At the axially opposite other end of the body section 50, the (blown) molded Z-container 100 has a shoulder section 80, which has the open container neck 70 in its axial extension or opens into it. The (in Figures 1 and 2c: upper) shoulder section 80 expands radially outwards from a container neck diameter d-70 in order to merge into the body section 50 with a (essentially vertically extending) lateral outer surface 60. The container neck 70 is arranged centrally in a shoulder inner region 81 of the shoulder section 80 which is radially inner around a (central) axial axis Z. The container neck 70 can be equipped with an exemplary screw cap with an internal thread as a closure (not shown; with reference numeral 90, cf. Figure 9 to the end product) are closed, for which purpose an external thread 75 is provided on the container neck 70.

Furthermore, the (blown) molded body Z container 100 is set up for vertical stacking during transport and/or storage. For this purpose, as can be seen in Figures 1, 2a and 3, an (optional) bottom trough 30 in the form of a substantially cup-shaped indentation is first withdrawn into the interior of the container in the direction of the axial axis Z in the frontal bottom surface 11 of the bottom section 20 (“dome geometry”). As shown in particular in Fig. 1, the bottom trough 30 tapers in a cup shape towards the interior of the container over a bottom trough depth t-30, starting from a first bottom trough diameter d-31 on the opening side up to a second bottom trough diameter on the base side. Diameter d-32 (e.g. 0 60 mm) of the inner base of the depression. Along the taper, the bottom trough 30 has a bottom trough shoulder 33 with a step-like third bottom trough diameter d-33 to a bottom trough depth t-30 (e.g. 52 mm).

The floor trough 30 (“dome geometry”, see especially Fig. 1) is specifically designed and shaped in such a way as can be seen in particular from the geometric “interplay” shown in Fig. 3, in order to ensure the vertical stackability of the (particularly several, identical) (Blow) molded body Z container 100 to accommodate the closed/closable container neck 70 (possibly with the closure 90 shown in FIG. 9) of another, identical (lower in FIG. 3) blow molded body Z (blow) molded container 100.

At the same time, the bottom trough 30 (“dome geometry”) reduces the residual volume remaining in the vicinity of the bottom surface 11 by damming up the, especially liquid, preparation. As a result, a (nominal) filling volume of the blow molded body/(blow) mold container 100 is optimized or almost completely guaranteed, since when removed, for example by means of a suction nozzle lance (as in the case of use according to the disclosure, for example on a dialysis machine), only a small amount is required Residual amounts remain in the (blown) molded body Z container 100. With reference to Fig. 2c, the (nominal) filling volume is based on a (nominal) filling height distance sF defining a target filling height, measured from an uppermost edge of the (blown) molded body Z container 100 (e.g. approx. 41 mm), marked. Included The (nominal) filling volume of the (blown) molded body Z container 100 can be, for example, approx. 4.7 liters.

The special shape structures on the bottom and shoulder sides and their functions when interacting to ensure vertical stackability are described in more detail with reference to Figures 1 to 5. On the one hand, a specific bottom-side shape structure can be seen, Figures 1, 2a, 2c, 3 to 5, whereby in particular the bottom surface 11 outside the bottom trough 30 must be taken into account as a relief-like bottom contour surface. On the other hand, in contrast to this, in a first approximation complementary, there is a specific shoulder-side shape structure, Figures 1, 2b, 2c, 3, 5. In principle, it is conceivable to use the special shape structure(s) or shape fit(s) (according to a possibly independent aspect) in any, in particular thermoplastic, shaping process such as blow molding, injection molding and the like.

The corresponding two mold structures, on the bottom side and on the shoulder side, ensure, in interaction/three-dimensional form fit, considerable stabilization of two identical stackable/stacked (blown) molded body Z containers 100, 100. In particular, FIG. 3 illustrates the special, axially spaced sections according to the disclosure , mold fit, in that a relevant section of a vertical stack arrangement 200 of two identical BlasformkörpemZ (blown) mold containers 100, 100 (one above the other) is shown in a longitudinal section according to a section plane AA defined in Figure 2b. Said form fit prevents/reduces lateral twisting and improves vertical stackability with the effect of anti-twist / “torsion-resistant” stackability:

The floor surface 11 outside the floor trough 30 is shaped as a relief-like floor contour surface. For this purpose, four axially retracted floor recess shape segments 22 (“concave”) are formed alternating with/adjacent to four axially projecting floor load contact shape segments 24 (“convex”). In other words, the floor contour surface is contoured three-dimensionally in a relief-like manner by alternating 4+4 shape segments with respect to its axial “height plane/line”. The four floor-load contact form segments 24 protrude over the floor between them. Recessed form segments 22 extend or protrude (in the direction of the floor surface 11 / towards a standing surface). In other words, the four bottom recess mold segments 22 are not part of what initially concerns a standing area of the (blown) molded body Z container 100. In this case, the four floor recess shape segments 22 are flatter or shortened in relation to the four floor load contact shape segments 24 in terms of an axial amount.

With reference to in particular Figures 2a and 4, the respective or all four bottom recess mold segments 22 extend radially. It can be seen that (optionally) the respective bottom recess shape segment 22 extends radially from the opening-side first bottom trough diameter d-31 of the bottom trough 30 in the transition of the bottom surface 11 to an outer circumference of the bottom surface 11 (in the transition to the outer lateral surface 60) extends.

Insofar as the (blown) molded body Z container 100 is essentially cuboid, with a substantially rectangular, almost square cross-section (see in particular Figures 2a, 2b, 4, 5), the bottom section 20 is in a cross-sectional plane perpendicular to the axial axis Z shaped with four corners. An exemplary mold container width B, see FIG. 2a, can be 148 mm; an exemplary mold container depth may be 158 mm. An exemplary mold container height h-100 (i.e. total height, over everything), see Fig. 2c, can be 290 mm; An exemplary molding height h-99 (without container neck 70) can be approx. 270 mm. In the transition between the associated lateral surfaces 60, the (blown) molded body Z container 100 can have a vertical side edge rounded with a container edge diameter D (e.g. 0 185 mm). All four bottom corners, as can be seen in particular from Figures 2a and 4, each have the four floor load contact form segments 24, which serves for an even, essentially symmetrical load distribution.

As can be seen in particular from Figures 1, 2bZc, 3, 5 for the shoulder-side three-dimensional shape structure, Z forms the relief-like shoulder section 80, outside the container neck 70, four protruding Z-convex shoulders (clearly visible in the top view of FIG. 2b: arranged in a cross-like manner). -Elevation shape segments 82 between respectively adjacent / intermediate shoulder load contact mold segments 84. In the present case, with reference to FIG. ) Molded body Z container 100) is shaped or set up to be spaced apart from each other in a contactless manner during stacking in a manner complementary to the corresponding bottom recess mold segment 22 (in FIG. 3: of the upper (blown) molded body Z container 100).

As a result, the load contact surface (in the background of the longitudinal section plane; see also reference symbol K in Figures 1 and 2c) on the shoulder side is (exclusively) divided into the (flat, falling in a cross-sectional plane) shoulder load contact form segments 84.

As can be seen in particular from FIG to be spaced contactlessly from the shoulder portion 80 of the same second (lower) (blow) mold container 100. The contactless spacing defines a gap dimension S. As a result, only the bottom load contact mold segments 24 of the (upper) (blow) mold container 100 form a load-bearing load contact surface on the further (lower) shoulder section 80. Again Z, complementary to this, the load contact surface is divided into four shoulder load contact form segments 84 on the shoulder side. The four shoulder load contact mold segments 84 are formed flat in a cross-sectional plane of the shoulder section 80 that is perpendicular to the axial axis Z (see especially FIGS. 1 and 5).

That is, the vertically stackable Z-stacked (blow) mold containers 100, 100 (only) come into contact with each other at the Z via the load contact surface. This interaction through the specific shape structures sufficiently stabilizes against undesirable relative movements. For this purpose, the four (lower) shoulder elevation mold segments 20 are fitted or set up for stacking to form a vertical stacking arrangement 200 (FIGS. 3 and 7) so that when stacked, they fit into the four bottom depression mold segments 22 of the same/further (upper ) (blow) molded container 100 to intervene in a form-fitting manner. This means that in the vertical stacking arrangement 200, the shoulder-side mold structure and the bottom-side mold structure, and thus both (blow) mold containers 100, 100, are blocked against relative rotation (against each other) about their own (which coincide with this) axial axes Z.

Insofar as, as already stated above, the bottom section 20 is rectangular in shape with four corners, each of which has associated corner-side floor load contact shape segments 24, the shoulder-side shape contour complementary forms a cross-shaped arrangement of the corresponding four shoulder elevation shape segments 82. Here, see Figures 1, 2b, 2c, 5, the four complementary shoulder elevation shape segments 82 are arranged in a cross shape around the container neck 70 and each extend radially from it. As shown in particular using the perspective view of FIG. 5, the four complementary shoulder elevation shape segments 82 each open into the container neck 70 with a continuously tapering contour line. Further with reference to Fig. 5, the four complementary shoulder elevation shape segments 82, as far as the opposite direction is concerned, widen out into an outer lateral surface 60 in the beginning fuselage section 50. According to the shape contour, each of the four (relatively retracted) shoulder-side corners, each of which comprises a shoulder load contact shape segment 84, is surrounded/ring-shaped with a protruding/stepped shoulder elevation shape edge 89 with a substantially rounded course, which with a to the shape of a suitcase corner.

For further anti-twist protection and stabilization in the area of the load contact surface of the vertically stacked (blow) mold containers 100, 100, there are a pair of radial grooves 28, 28 arranged in pairs on the bottom side, see especially Figures 2a and 4, per respective corner-side bottom load contact mold segment 24 / two, convex / into the interior of the container (or vice versa, modification not shown: concave) contoured (at least partially radially extending) bottom shape structural elements shaped. Complementary to this are a pair of radial longitudinal curvatures 88, 88 arranged in pairs/two, concave (or vice versa, modification not shown: concex) contoured (at least partially radially extending) shoulder mold structure elements are formed. In other words, on each corner side the pair of radial grooves 28, 28 as the bottom shaped structural elements is or are suitable for (or shape-fitted to) the associated pair of radial longitudinal bulges 88, 88 as the shoulder shaped structural elements. In other words, in the sense of improved stability of a vertical stacking arrangement, the radial longitudinal curvatures 88, 88 (from above) fit/press/'latch', so to speak, into the matching radial grooves 28, 28 (below) in order to rest against one another in a form-fitting manner. This serves in the form of a lock to further secure a tower-like stacking arrangement 200 (FIG. 7) against slipping, twisting and tipping of the (blow) mold containers 100, 100.

Furthermore, as shown in Figures 1, 2c, 4 and 5, the (blow) molding container 100 optionally has a formation of a plurality of mutually parallel (stiffening) ribs 55, 55,... with rib grooves 57, 57 in between ,... which run around the fuselage section 50 essentially transversely/perpendicular to the axial axis Z (i.e. “horizontal” rib structure).

The handle 113 can be provided (optionally) flatly and (optionally) in the form of a film strip in a fixed manner Z. In particular, the handle 113 can be glued on.

The handle handle 113 forms a handle handle center section 119 which runs in the shape of a round bow between the two handle handle ends 118, 118 and axially beyond the shoulder section 80. The handle 113 with its two opposite handle ends 118, 118 sticks tangentially to two associated connection points P of two opposite outer lateral surfaces 60 of the (blow) mold container 100 Z of the fuselage section 50. The handle 113 is with respect to the two connection points P respectively attached off-center. As illustrated in particular in FIG. 10, the handle 113 can be attached offset in a transverse direction from a plumb point L falling in a cross-sectional plane from the axial axis Z. The handle 113 is positioned obliquely to the axial axis Z in the two connection points P. In this case, a handle handle angle {90°-W} defined between the axial axis Z and a longitudinal extension line of the handle handle 113, selected as an example, is approximately 32 degrees (to the vertical).
