  • US 2004/0112918 A1 discloses a liquid dispenser comprising a deformable flexible bag provided with an opening, a flexible bag carrier to which the opening of the flexible bag is attached, and a pump mounted on the bag carrier for withdrawing a fluid from the bag.
  • a liquid pump container which has a housing made of two housing parts that are connected to one another in an articulated manner and a flexible bag with an outlet block arranged on the top of the bag and provided with an outlet hole.
  • the two housing parts are opened up, the bag is inserted so that the outlet block protrudes from the housing, and then folded up again.
  • a similar liquid pump container is from the US 6,619,505 B1 known, but in which the two housing parts can be plugged together.
  • a liquid dispenser is still available from the US 2005/0077319 A1
  • the liquid dispenser includes a fluid reservoir with a rigid neck, a rigid housing containing the fluid reservoir, a dispensing element engaging the neck of the fluid reservoir, and a retaining element engaging both the neck of the fluid reservoir and the rigid housing to retain the container in the rigid housing.
  • a liquid dispensing container is in the WO 2022/047527 A1 which comprises a container body, a liquid dispenser and a removable bag unit which can be replaced by a replacement bag.
  • the liquid dispenser has a flexible bag with an opening, a bag carrier to which the opening of the bag is attached, and a pump.

  • a fluid pump unit can be connected to an exchangeable inner container, wherein the fluid pump unit and the inner container can be inserted laterally into the lid element together as a unit through the slot.
  • the inner container can be replaced.
  • the inner container is detachably connected to the fluid pump unit, for example by screwing. Since the inner container is a replacement part, it is not considered to be part of the fluid dispenser in the narrower sense.
  • a fluid dispenser with an accommodated inner container can be considered to be a fluid dispenser device, i.e. the fluid dispenser device comprises the fluid dispenser and the replaceable inner container, which is detachably connected to the fluid pump unit and accommodated in the outer container.
  • the fluid pump unit is referred to below as the pump unit.
  • the fluid dispenser is reusable and therefore environmentally friendly and saves resources.
  • the inner container in which the fluid to be removed is stored, is preferably intended as a replacement part for single use, but can also be refillable.
  • the fluid dispenser in particular the outer container and the lid element, can be made of a different material than the inner container. This means that a material adapted to the respective function can be used.
  • the inner container can be made of a material that is as inert as possible with regard to the fluid, particularly in the areas that come into contact with the fluid.
  • a new plastic material (virgin resin) is preferably used for this purpose.
  • the inner container can be made entirely of new polyethylene (PE) or new polypropylene (PP), which are often also referred to as virgin PE or virgin PP.
  • PE polyethylene
  • PP new polypropylene
  • the inner container is then constructed in one layer.
  • the inner container can be constructed in at least two layers and have an inner layer made of new polypropylene or new polyethylene and an outer layer made of a different material, for example recycled polypropylene or recycled polyethylene or another plastic material, in particular recycled plastic material.
  • the inner container or the inner layer of the inner container is preferably made of new polyethylene, since polyethylene is more flexible than polypropylene.
  • the inner container is in particular made of a flexible material, in particular if the inner container is designed in the form of a liquid bag, for example.
  • New plastic material differs from recycled plastic material in particular in terms of its purity.
  • the use of new polyethylene (PE) or new polypropylene (PP) therefore allows the properties of PE or PP to be adjusted more precisely and thus better adapted to the requirements in the cosmetics sector with regard to purity and inertness.
  • the outer container and the lid element in particular can be made of a different plastic material.
  • the outer container and the lid element can be made of the same plastic material as the inner container.
  • the outer container and the lid element can be made of polypropylene (PP) or acrylonitrile butadiene styrene (ABS), which can be new plastic material or recycled plastic material.
  • the outer container and/or the lid element can each have a single layer or at least two layers.
  • an inner layer of the outer container and/or the lid element can be primarily responsible for mechanical stability, while an outer layer is adapted for improved haptics (grip) and/or printability.
  • a fluid dispenser 100 comprises a dimensionally stable outer container 110 with a container opening 113 at its upper end, as for example in Figure 2
  • the outer container 110 is designed to accommodate a replaceable flexible inner container 140, wherein the inner container 140 can be inserted into the outer container 110 through the container opening 113.
  • the outer container 110 preferably has a base 111 and a circumferential side wall 112 extending from the base 111, wherein the base 111 and the side wall 112 delimit a receiving space for the inner container 140.
  • the base 111 is preferably designed as a closed base, but it can also be partially open. The base 111 improves, among other things, the dimensional stability of the outer container 110.
  • the outer container 110 can have a cylindrical shape, wherein the cross section, ie the outer cross section, of the cylindrical outer container 110 can be circular or as in Figure 2 shown can be rectangular with rounded corners (rounded rectangle).
  • the dimension of the rounded rectangle in its longitudinal direction is at least 1.5 times larger, in particular at least 1.8 times larger or even at least 2 times larger, than the dimension of the rounded rectangle in its transverse direction.
  • the radius of all rounded corners is the same, and it can be selected so that straight sections remain on both the long sides and the two end faces of the rounded rectangle.
  • the radius of the rounded corners can be equal to or less than half the extent of the rounded rectangle in its transverse direction.
  • the radius can, for example, be between 0.1 and 0.4 times the extent of the rounded rectangle in its transverse direction.
  • the side wall 112 of the outer container 110 can comprise two mutually opposite flat wall sections and two at least partially curved wall sections connecting the flat wall sections to one another.
  • the flat wall sections are preferably parallel to one another and correspond to the long sides of the rounded rectangle.
  • a maximum distance between the straight wall sections is smaller than a maximum distance between the at least partially curved wall sections. The relationship between these distances can correspond to the relationships between the transverse direction and the longitudinal direction of the cross section described above.
  • the partially curved wall sections can each be formed by a flat wall section and two lateral round wall sections, whereby the round wall sections have a radius that corresponds to the radius of the rounded corners. All wall sections preferably merge seamlessly into one another, so that the outer container has a seamless outer contour in the circumferential direction.
  • the cross-sectional shape (shape of the outer cross-section) of the outer container 110 is adapted in particular with regard to the handling of the fluid dispenser 100.
  • a cross-section in the form of a rounded rectangle has proven to be advantageous, since the user can grip the fluid dispenser 100 better with one hand.
  • this cross-section is also advantageous with regard to the use of the inner container, since the inner container 140 also has a more elongated and narrower cross-sectional shape.
  • a cross-section in the form of a rounded rectangle is also advantageous with regard to a higher packing density when packing several fluid dispensers 100 in a box or other transport container. In the case of fluid dispensers with a more circular cross-section, however, larger gaps remain when packing several fluid dispensers in a box.
  • cross-sectional shape as a rounded rectangle is also advantageous when placing several fluid dispensers 100 on a shelf or on a console, which is particularly appreciated by professional cosmetic studios and hair salons.
  • the base 111 and the side wall 112 merge integrally into one another, wherein in particular the receiving space from the base 111 to the container opening 113 has a substantially constant cross-section.
  • the circumferential side wall 112 extends from the base 111 to the container opening 113, wherein the container opening 113 is formed by the upper side edge of the side wall 112.
  • top, bottom and side are understood as directional indications defined by the outer container.
  • the longitudinal extension of the outer container 110, as in the Figure 2 shown, defines a vertical direction, so that the bottom 111 is therefore arranged at a lower end and the container opening 113 at an upper end of the outer container 110.
  • the designations “downward”, “bottom”, “upward” or “top” therefore represent directional information with respect to this vertical direction
  • the fluid dispenser 100 further comprises a dimensionally stable lid element 120 for closing the container opening 113.
  • the lid element 120 delimits a cavity and has a first opening 121a at a first end of the lid element 120, an opposite second opening 121b at a second end of the lid element 120 and a lateral slot 121c extending from the first opening 121a to the second opening 121b, which can be closed with a detachable closure element 122 of the lid element 120.

  • the transition between the shoulder section 121e and the neck section 121d does not necessarily have to be step-like, but can also be continuous.
  • the cover element 120 can therefore have a step-like or continuous transition between the first opening 121a and the second opening 121b, particularly on its outside.
  • a step-like transition is preferred, since this is easier to produce in terms of production technology and requires a smaller extension of the cover element 120 in the vertical direction.

  • the user can put the outer container 110 to the side, with one hand the main part 121 and with With the other hand, grasp the unit consisting of the inner container 140 and the pump unit 150, and thus separate the main part 121 from the rest of the unit. This state is, for example, in Figure 4F to recognize.
  • the inner container 140 is then replaced by a new inner container 140, the pump 152 is inserted into the mouthpiece 142 and screwed to it or locked via a bayonet connection. This again forms a unit consisting of the inner container 140 and the pump unit 150.
  • the main part 121 is first pushed completely over its slot 121c onto the unit consisting of the inner container 140 and the pump unit 150 ( Figure 4G ) and the inner container 140 is inserted through the container opening 113 into the outer container 110 until the main part 121 is completely inserted into the container opening 113 again ( Figure 4H ).
  • the two shell halves can be elastically moved towards each other by applying light pressure from the outside, in order to slightly reduce the clear external cross-section.
  • the user can reduce the pressure on the shell halves, causing the two shell halves to elastically return to their original position, thereby pressing the outer step 121f against the inner step 112a.
  • the closure element 122 is then reinserted into the slot 121c, whereby the support surfaces 121g on the edges of the slot 121c serve as a guide for the closure element 122 ( Figure 4I ).
  • the closure element 122 braces the two shell halves so that they are no longer elastically moved against each other by pressure from the outside.
  • the closure element 122 thus serves not only to optically close the slot 121c, but also to secure the main part 121 and thus the entire lid element 120 in the container opening 113 of the outer container 110.
  • the pump unit 150 is completely lowered again so that the pump head 151 engages around the upper region of the neck portion 121d and thereby secures the closure element 122 against being pushed out of the slot 121c.
  • the closure element 122 may, according to an embodiment which may be suitably combined with other embodiments described herein, have a step 122a on its lower front side which comes into contact with the edge of the container opening 113, as for example in Figure 2 shown.
  • the step 122a engages in the container opening 113 and thereby prevents the closure element 122 from being pushed forward easily. Since the step 122a preferably has only a small extension in the vertical direction compared to the outer step 121f, the closure element 122 only needs to be lifted slightly when removed from the slot 121c so that it can pass the upper edge of the container opening 113. Alternatively, the closure element 122 can also be tilted about the step 122a engaging with the container opening 113 if the pump head 151 is raised sufficiently.
  • the closure element 122 can also perform a display function.
  • the closure element 122 can be provided with a print or with a color that allows a clear conclusion to be drawn about the fluid in the inner container 140.
  • different fluids can be marked with different colors, for example shampoos can be marked with a first color and conditioners with a second color. This can prevent accidental confusion during use, thereby ensuring that the correct fluid (cosmetic liquid) is used.
  • FIG. 5A to 5C show fluid dispensers which are prepared for dispensing different fluids.
  • closure elements 122 in different colors which are unique for the respective fluid are used.
  • the fluid can be clearly and easily identified not by the color of the closure element 122, but by an additional marking element 160, which is inserted into a holder on the pump head 151. is inserted interchangeably.
  • Figure 5A shows, for example, an embodiment in which the color of the marking element 160, but not the color of the closure element 122, is specific to the fluid.
  • the embodiment in Figure 5B has no holder for a marking element, so that in this case the coloring for the closure element 122 is used for easy recognition of the fluid in the fluid dispenser.
  • the embodiment in Figure 5C has a holder on the pump head 151 for receiving a marking element 160, whereby in the Figure 5C In the embodiment shown, both the color of the marking element 160 and the color of the closure element 122 are used for the unique identification of the fluid.
  • the outlet 154 formed on the pump head 151 can point in the direction of the closure element 122, i.e. forwards ( Figures 5B and 5C ) or away from the closure element 122, i.e. to the rear ( Figure 5A ).
  • the orientation of the outlet 154 is typically not limited, as the pump head 151 is preferably rotatable about the pump 152 so that the user can orient the outlet 154 according to his needs.
  • FIGS. 6A 6A to 6C show further three-dimensional views of a fluid dispenser 100 with a marking element 160 according to an embodiment, which can be combined as desired with all other embodiments described herein.
  • the marking element 160 can, for example, have the shape of a coin or a round chip and can be inserted laterally into a semicircular holder 155.
  • the fluid dispenser 110 can be offered for sale without the inner container 140. However, it is also possible for the fluid dispenser 110 and the inner container 140, which contains a fluid, to be offered for sale together as a kit in a common or different packaging.
  • the closure element 122 and the optional marking element 160 can be supplied in a color that is unique to the fluid in the inner container 140.
  • an inner container 140 containing a fluid it is possible for an inner container 140 containing a fluid to be offered as a kit together with a marking element 160 and/or a closure element 122 for replacement of an empty inner container.
  • the inner container 140 and the marking element 160 and/or the closure element 122 can be offered in a common packaging.
  • the closure element 122 can and/or the marking element 160 is supplied in a color that is unique to the fluid contained in the inner container 140.
  • the fluid dispenser 100 with outer container 110, cover element 120 and pump unit 150 is reused, while the inner container 140 can be replaced and fed into a material recycling system.
  • the coloring of the closure element 122 and/or the marking element 160 makes it easy to recognize the fluid in the fluid dispenser 100, the outer container 110 and the main part 121 of the lid element 120 do not have to be printed or colored specifically for a certain fluid. This makes it possible, for example, for the user, for example an employee in a hair salon or a cosmetic studio, to have several fluid dispensers 100 in stock, which he can keep ready with different inner containers 140 for different fluids as needed.
  • the solution described here allows a material- and resource-saving use of fluid dispensers that can be filled with different fluids.
  • the replacement of the inner container 140 is made considerably easier for the user by the lateral slot 121c in the cover element 120, since the unit consisting of the inner container 140 and the pump unit 150 can be completely removed from the cover element 120, so that this unit is freely accessible to the user for removing the emptied inner container 140 from the pump unit 150 and connecting the pump unit 150 to a new inner container 140.
