Description

 Food container with integrated mouthpiece and pump

description

The invention relates to a food packaging for flowable and prepared for consumption food, which is both a sales package, as well as a packaging from which the food can be taken directly.

The packaging used at present for foodstuffs which merely need to be heated for consumption (ready meals and soups) are unsuitable for this purpose. Ready-to-serve meals and soups are also available in tin cans, ready-to-serve meals frozen in plastic bags or in cardboard packaging. These conventional types of packaging prevent the benefits of these foods from fully exploiting, as they do not allow for direct consumption from the sales package.

The food packaging according to the invention should also make it possible to consume viscous foods, such as yoghurt preparations, quark foods, dessert creams, soft ice cream or sorbets, without aids, directly from the packaging.

It is therefore the object of the invention to provide a food packaging which is improved over the conventional types of packaging and which is intended to be particularly suitable for fluid foodstuffs of quite different consistency and to offer superior consumer utility properties by offering the possibility of directly dispensing the food to consume the packaging, the content may be previously heated. It includes the essential idea to integrate in the packaging container as a conveyor manually operated air pump for metered discharge of the contents via a mouthpiece attached to the container.

In DE 32 02 275 A1 and DE 82 20 965 U1 packaging containers for food are described with an integrated conveyor. In both inventions, they consist of a bellows at the bottom of the package and a sliding bottom of a rigid-wall, cylindrical container. In the face of the bellows is an opening that is closed with a finger or the thumb and pressed at the same time. In this case, the flexible bellows is compressed and exerted an air pressure on the sliding floor. In DE 82 20 965 U1, the bellows is additionally surrounded by a rigid, displaceable sleeve. At the top of the packaging are the discharge openings.

A disadvantage of both inventions is obviously the uncomfortable handling of the pump, as a pressure on the packaging in the direction of the mouthpiece from must be practiced. Precise metering under the load of a larger amount of food is therefore likely to be difficult. Stopping the packaging according to DE 32 02 275 A1 is not possible because the flexible bellows would tip immediately to the side. In addition, the packages appear to be suitable only for smaller quantities, since no provision is made to prevent the sliding floor from slipping back automatically under a greater load.

It is therefore an object of the present invention to design a food packaging so that it has a comfortable handling and safe operation is guaranteed. In particular, a precise dosing when discharging the contents of the package should be possible, the operation of the pump from a comfortable position of the hands done, in which the package can be held securely at the same time.

In principle, the proposed food packaging should be feasible both as disposable and as reusable packaging. Although the pump is functionally part of the invention, it can also be designed as a separate part of a modular construction. You can with other, separately manufactured parts (foot, container wall, ...) screwed or pluggable or be made connectable by similar connecting means.

Particularly suitable is the proposed food packaging for food preparations with a certain solids content, which are heated before consumption and therefore on the one hand can not be removed via a drinking straw and on the other hand require a finely dosed discharge.

In the embodiment of the invention, the proposed food packaging has a food storage space with a displaceable and / or deformable wall portion, which is configured and arranged with respect to the pump, that under the action of the pump, the food storage space can be reduced to a vanishing volume. Thus, the content is completely removable without dexterity of the user.

In the realization according to the invention, the pump acts according to the principle of the air pressure pump with intake of ambient air into the food container, in particular into a pressure space adjacent to the food storage space. This embodiment is particularly advantageous in that it uses the ambient air as a "propellant gas" in a completely environmentally neutral manner. [. Hierbei] In this case, valves are provided on the mentioned air pressure pump with which ambient air is drawn to the pump on the one hand and compressed ambient air for pressurizing the container contents on the other hand Specifically, this embodiment is characterized by a pump associated first Einwegventii for connection to the atmosphere, which is arranged in particular in or adjacent to the lower end face of the food container and a pump connecting to the pressure chamber second one-way valve.

In a first, simple realization of this idea, it is possible with a rotating or rotary piston pump to be designated pump by turning a conveying of the food through the mouthpiece of a movable part of the pump with respect to a part of the pump fixedly connected to the food container. This design is easily handled by virtually any user - even smaller children, as well as older people - and the discharge rate is on the speed and / or amplitude of the rotational movements finely dosed.

Particularly suitable for many applications is an embodiment of the proposed packaging with a substantially cylindrical or even, together with a deformable inner container, truncated outer shape, wherein the mouthpiece is arranged on or adjacent to an upper end face and the pump near a lower end face. Here, modifications of the simple basic form under aesthetic and / or promotional aspects are readily possible.

In a simple and inexpensive to produce and advantageously integrable in the actual packaging container first embodiment of the invention, the above-mentioned embodiment of the pump in the manner of a rotary piston pump concentrically formed, radially extending and paired ribs corresponding to each other such that upon rotation of the two pump parts a compression of sucked ambient air takes place in the mentioned pressure chamber against each other.

To reduce the manufacturing and thus cost of the integrated pump, the active members of the valves are preferably clamped to an adjacent wall in their execution as an air pressure pump, but it can also be used on adhesive bond or a connection by welding plastic parts.

A cost-effective as a mass product (advantageously also disposable packaging) producible food container of the proposed type is as a plastic injection molded part or blow molded part, in principle with established for the known plastic yogurt cups or PET bottles technologies to produce. Depending on the relevant market segment (low-priced or high-priced article), it is possible to choose particularly cost-effective or somewhat more valuable plastics and an adapted finish of the outer wall. A version in parts of coated paper or thin cardboard is also possible.

A rotatable outer wall portion, which belongs to the aforementioned advantageous pump, can be highlighted by special structuring and optionally also salient coloring for the user and thus the specific high-tech functionality of the packaging container can be highlighted. In addition, the color and tactile differentiation between fixed and rotatable wall sections in the sense of user guidance and make additional (printed) instructions for use largely unnecessary. In addition to the aforementioned embodiment of the integrated feed pump, further conveying devices according to the invention which are designed as integrated, manually operated air pumps are described below.

To avoid the ingress of container contents (food) into the effective range of the pump, the mentioned food storage space can be separated from the pump or the associated pressure chamber by a special wall (such as a thin film). In this way, a meaningful variant of a reusable design can be realized, in which a separately manufactured (and sold) Foiien- packaging with the food content can be inserted into an outer, mechanically rigid and the pump containing container body. Alternatively, a backup of the pump action range can be realized against contamination by penetrating container contents as well as after the air bubble or Luftdom principle.

In the embodiment as a packaging container of the container according to the invention, in particular with ready-made soups and other ready meals, including frozen products. Quark foods, ice creams, sherbets and other dairy products and desserts, certainly with thicker drinks, such as drinking yoghurt, but also be supplied with low-viscosity drinks - being particularly suitable for mixtures with non-uniform consistency and especially solid ingredients.

For the presented food packaging, it is possible to install in the container for the food an intermediate wall by the food storage space is divided into two parts. This variant of the invention makes it possible to store two different foods separately in the container and to convey them separately or simultaneously through the mouthpiece. These could be, for example, a main course and a side dish to this dish. For this purpose, two separate pressure chambers and equipment with one or two suitable for this purpose air pumps are required. Such pumps will be described in detail below.

16 to 32 show further examples of air pumps for food packaging according to the invention,

Figs. 33 to 36 relate to an embodiment of the food package having two separate food storage spaces and pressure spaces. Figs. 33 and 34 show cross sections of an arrangement with two pumps in the bottom of the food container. Figs. 35A to 35D show the function of a variant of the first 36 shows a longitudinal section of this pump in the representation of the promotion of a right-hand part of the foodstuff storage space.

Fig. 1 shows a schematic longitudinal sectional view of a plastic soup cup, a ready meal container or a beverage container 1 as a food container according to an embodiment of the invention. The soup cup serves to receive a soup preparation or ready-to-serve meal which can be heated in the cup by microwave, which is located in a foil bag 3 in this embodiment. It has a cylindrical wall 4 and an integrally formed lower end face 5 with a slightly downwardly protruding foot 7 and a pressed-on cover 9 as an upper end face. The lid 9 has an integrally formed mouthpiece 11, which is provided in the delivery state with a closure cap 13. The cover is protected by a peripheral edge 4c of the wall 3, is held by the possibly spilled food.

Between the lower end face 5 of the cup for the food and a substantially parallel to this extending stiffening intermediate wall 15, a pump 17 is provided, which is indicated in the figure only symbolically with coarse hatching. In one embodiment, as an air pressure pump, these are a first one-way or check valve 19 in the lower end face 5, which establishes a connection of the food packaging 1 with the atmosphere, and a second one-way valve 21 in the intermediate wall 15, which the pump 17 with a below of the film bag 3 to be formed variable pressure chamber 23 connects, which is bounded above by a piston 25 which is airtight received in the cylindrical container wall 4 and vertically slidably. in the In the area of the pump 17, the container wall 4 has a section 4a separated from its upper section and rotatable relative thereto, the function of which will be described in more detail below. The pump 17 is manually operated (as will be explained in more detail below) and metered pressure in the pressure chamber 23, whereby the piston 25 is pushed up and fed from the foil bag 3 through the opened mouthpiece 11 soup in the mouth of the user becomes. In Figs. 2A and 2B (as a cross-sectional view) and in Figs. 3 to 9 (in perspective views), the structure of the pump 17 will be described more specifically, and this structure and the function of the pump will be explained below. It should be noted that Fig. 1 is merely a schematic representation, so that the correspondence between this figure and the representation of the pump serving figures is not given in every detail. The pump 17 accordingly consists of an upper part 27 and a lower part 29, which at the same time can form the base 7 or the feet of the food container. Finally, in a certain sense, the piston 25, as shown in Fig. 9 in a version with a curved surface, belongs to the pump 17. Essential parts of the pump components 27, 29 are the respective outer wall portion 4b and 4a of the food container, each an inner wall 31 and 33 and two each extending between the inner and outer walls, in the illustrated embodiment in cross section circular-segment-shaped pivot piston 35a, 35b and 37a, 37b. FIGS. 2B, 3 and 5 relate to the pump top 27, while FIGS. 2A, 4 and 7 refer to the pump bottom 29. In Fig. 2B, the pivoting pistons 37a and 37b, which actually belong to the pump base, shown in dashed lines. Fig. 8 shows a perspective partial view of the lower part of the container 1 with the wall 4 and the bottom 15 from above, are provided on the stiffening ribs 15 a. These also serve to stabilize the piston in its initial position (state of delivery of the cup 1).

With its upper part 27, the pump 17 is screwed to the lower end of that portion of the food container, which receives the foil bag 3. The internal thread 38, which is easy to recognize in FIG. 5, serves for this purpose in the upper region of the inner wall. The outer wall 4b of the upper pump part 27, which forms a continuation of the wall 4 of the upper container portion from the diameter, differs from that by a corrugation, as can also be seen in Fig. 5. The connection between the upper pump part 27 and the lower pump part 29 is made via an annular groove 40 in the upper part with short vertical branches 40a on the upper part of the pump and on the annular groove 40 matched slider 40b on the inner wall of the lower pump part 29, via the vertical branches 40a can be inserted into the annular groove 40 and run tangentially there in the assembled state of the pump. In the detail illustration of FIG. 3, a ramp is shown, over which the slider 40b has to be pushed during assembly, in order then to lock in the annular groove.

As can be seen in FIGS. 2A and 4, the lower pump part 21 has two pressure compensation openings 39a, 39b in the bottom, while the upper pump part 27 - as FIGS. 2B and 3 best show - a pressure equalization connection of the spaces between the pistons 37a, 37b and the space inside the inner wall 33, where the valves 19 and 21 are arranged, is provided by connecting slots 41a, 41b.

Fig. 6 shows a view of the valve 21, designed here as a flapper valve. The valve flap 21b, which can close the opening 21c, is integrally connected in this embodiment with a surrounding ring 21a, which serves to attach the valve flap. As can be seen in Fig. 5, the valve 21 is in a recess. With the help of the ring 21a, the valve flap 21b is clamped on its side walls.

The pump 17 is actuated by the user comprising the food container 1 with one hand in the upper portion of the container wall 4 and with the other in the separate portion 4a and the portion 4a is rotated relative to the portion 4. As a result, the pump upper part 27 is rotated relative to the pump lower part 29. As the cavities 62a and 62b (see FIG. 2B) increase in size, air is drawn in from the environment via the lower valve 19, when it is rotated in the opposite direction, it is compressed and via the upper valve 21 into the space below the pistons 25 issued. The piston 25 is thereby pushed up and compresses the foil bag 3 together, whereby the leakage of content from the same through the mouthpiece 11 is effected in the mouth of the user. The manual setting of the angle of rotation and, with multiple turns, the frequency of these movements, a dosage of the leaking food or the food can be easily specified as required by the user.

Fig. 10 shows an overall perspective view of the food container 1 in the well a preferred Außenflächenstrukturierung (corrugation) of the essential for the operation of the pump lower sections can be seen.

Figures 11 to 13 illustrate an advantageous embodiment of the mouthpiece, in which this is sunk in the delivery state in the pressed-on lid 11 and is pulled out before use by the user and also (as shown in FIG. 13) can be slightly inclined.

14 is an exploded view of a pump with the parts exploded along the broken line and the pump side wall 4d (FIG. 15) omitted for clarity; FIG. 15 is a longitudinal section of the same pump. They show a variant of the previously presented pump and works similarly, but has no annular groove and sliding pin. This is an advantage in the production because simpler tools are sufficient. chen. The housing consists here of a single part, wherein in the manufacture of the upper end plate 6 is pressed into the side wall 4d (4a and 4b of Figures 1, 3, 4, 5 and 7 are integrally connected here). The end plate 6 has an opening from which the inner wall 31 protrudes. The inner wall is here compared to the version of the pump of Figures Fig. 3 and 5 extended. Face plate and inner wall are not connected to each other, but close off sealing and can be rotated against each other. With the inner wall 31, the pivot pistons 35a and 35b, with the housing outer wall, the pivot pistons 37a and 37b are firmly connected. The pump is connected to the container by inserting the extended inner wall 31 into a mating opening of the container bottom. In Fig. 14 this is indicated by the double arrow. The pump is actuated by repeatedly rotating the pump housing against the side wall of the tank.

Figures 16 and 17 show a food container with a simple piston pump in which the piston 45 is linearly displaced. It is firmly connected to a piston rod 46, which in turn is connected to a bracket 47 on the outside of the container. This bracket serves as an actuating element for the pump and is elastically deformable. This pump can be operated with only one hand by pressing the bracket against the container side wall. In this case, the pump piston 45 is displaced so that the pump interior is reduced, wherein the inlet valve 19 closes, the outlet valve 21 opens and air from the pump interior 62 is pressed into the pressure chamber 23. After the end of operation, the bracket takes its initial shape again and pulls the pump piston 45 in its original position. In this case, the outlet valve 21 closes and by the opening inlet valve 19, outside air is sucked into the pump interior 62.

In FIGS. 18 to 20, a piston pump for the food container is presented, in which a cavity 62 with rigid walls inside the pump, the pump working space, is formed from two parts, which are displaceable relative to one another. In the rest position, the two parts are pushed apart by two leaf springs 48 (FIG. 18), which are clamped between abutments 51, on the fixed 49 and the displaceable 50 wall sections. The displaceable wall section protrudes somewhat in the rest position through an opening in the pump outer wall and represents - seen from the outside - a kind of button that can be pressed. When pressed (FIG. 19), the cavity narrows, the inlet valve 19 closes, the outlet valve 21 opens, and air is forced into the pressure space 23. When released, the leaf springs 48 relax, the slidable wall portion 50 returns to its original position, the outlet valve 21 closes, the inlet valve 19 opens and air is sucked. The opening 52 is optional and represents a variant of the pump; if it is present, the inlet valve 19 can be omitted, it must be closed by pressing the button with your finger.

Figures 21 and 22 show a pump for the food container with a bellows 53 made of an elastically deformable material. The pump The mechanism is similar to that of the previously presented pump. It is here used elastically deformable walls for the cavity. In contrast to DE 32 02 275 A1 and DE 82 20 965 U1, an outlet one-way valve 21 is additionally used in this design in order to prevent the conveyed material from sliding back after the pump has been actuated. The horizontal arrangement of the bellows allows a much more comfortable handling than in the mentioned inventions.

In FIGS. 23 and 24, a pump is realized by means of an elastically deformable wall 54 of a cavity 62 in the interior of the pump. As in the previously described pumps, the cavity is equipped with two one-way valves. The wall 54 partially shifts as it deforms along rigid walls perpendicular to it. The operation of the pump by means of a lever 55 which is connected to the wall 54 via a hinge 56. The return of the deformable wall 54 in its initial shape and position can be supported with an optional spreading spring 57.

Figures 24, 25 as cross-sections and 26 as a longitudinal section, and 27 and 28 in a perspective view show a particularly easy to implement pump for the food container. Between an upper 58 and a lower 59 face plate, which are arranged parallel to each other at a distance of slightly more than a finger width, there is a strip 60 made of an elastically deformable material which is annularly closed and can be almost arbitrarily shaped and / or folded (one could use the approximately finger-width section of a tube with a circular cross section as a particularly simple form). Together with two end plates 58, 59 which are fixedly connected to each other via two struts 61a, 61b, the strip 60 forms a closed cavity 62. At the edges of the end plates is in each case a circumferential bead, which serves as a limiter 63a, 63b for the displacement serves the strip 60 and prevents that an undesirable opening in the cavity 62 may arise. In the lower 59 end plate is a one-way valve 19, which serves as an inlet valve, can be sucked through the outside air. In the upper 58 face plate is the outlet valve 21 for connection to the pressure chamber 23. The pump is actuated by the strip 60 is compressed either with the thumb alone or together with the index finger or with the middle finger. As a result, the volume of the cavity is reduced and - similar to in previously described pump designs - closes the inlet valve 19, the outlet valve 21 opens and air flows from the cavity 62 into the pressure chamber 23. An attachable hand rest 64 is used comfortable handling. As shown in Fig. 26, it can also be plugged upside down (dashed 64 '), it serves as a space-saving storage of food packaging. In addition, it protects the pump from accidental and unauthorized operation and soiling - it acts as a transport safety device.

FIGS. 29 to 32 show a further embodiment of a delivery pump according to the invention. FIGS. 29 and 31 illustrate the condition of the pump before operation, and FIGS. 30 and 32 illustrate the condition during the operation Activity. Similar to the pump described above, in this pump, two end plates 58, 59 are parallel to each other at a distance of about one finger width and are connected to two struts 65, 66. Likewise, a one-way valve is located in the two end plates. Two rotary pistons 68a, 68b, the height of which corresponds to the distance between the two end faces, are connected via a gear coupling 70 such that when one of the two pistons rotates, the respective other piston rotates in the opposite direction. The strut 66 is shaped so that in each position of the two rotary pistons 68a and 68b sealingly abuts against them. In the position of the piston as in Fig. 30, they are over a recess of the end plate 59 in which the inlet valve 19 is slipped away. The valve covers 72 prevent air from escaping below the pistons during this movement. The two end plates, the two rotary pistons, the gears 70 and the strut 66 together form a cavity 62, the size of which changes when the pistons are rotated. By pressing one of the two buttons 71, the pump is actuated, thereby tensioning the leaf spring 69, when you release the keys, it rotates the piston back to its original position. As in the case of the pump of FIGS. 24 to 28, a hand rest can be attached at the lower end, which can be placed on the other side as a transport lock.

Fig. 36 shows a food container in longitudinal section in which the food storage space is divided by an intermediate wall 75 into two parts. Such a food packaging would be suitable, for example, to keep a main course and a side dish separately and to promote separately. It could be equipped by an arrangement of two separate working pumps. Figures 33 and 34 show an example of such an arrangement in cross section. There is some similarity to the pump design of Figures 29 to 32. However, the pumps are not coupled here. Fig. 33 shows both pumps in the rest position, Fig. 34 shows a pump on the left side during its operation, the right pump in this figure is not actuated. For both pumps are each a separately operating inlet valve 19, and in each case an outlet valve, which establishes the connection to the two separate pressure chambers available.

The pump of Fig. 36 and Figs. 35A to 35D can also convey the contents of two food storage spaces. It is a variant of the pump of Figures 2A, 2B, 3, 4, 5 and 7. In contrast to that pump, this pump has only a pair of rotary pistons, one rotary piston is fixed to the lower 29 and the upper 27 pump half connected. It is thereby possible to turn the two pump halves against each other to a much greater extent. The hollow cylindrical inner wall 33 on the lower pump part has in this embodiment at the upper end side a cover 73 which is fixedly connected to it and has an eccentric opening 74. The connecting slot 41 a in the inner wall of the pump upper part 27, Fig. 3, which establishes the connection from the cylindrical cavity to the cavity between the pivoting piston, is located here on the pump lower part 29 in connection with the pivoting piston (see Fig. 35B). The inner wall 31 of the pump top 27 has no connection slot (FIG. 35A). The cylindrical hollow The cavity of the inner wall 31 of the upper pump part is divided into two parts by a wall 75 '. It represents an extension of the intermediate wall 75 of the food storage space and closes with the lid 73 sealing. Depending on the position of the pump lower part 29 relative to the pump upper part 27, a connection is made via the pressure chambers 23a or 23b to either a left (2a) or a right (2b) half of the food storage space. When selecting a pivoting range in which the opening 74 is located either to the left or only to the right of the intermediate wall 75 ', the respective halves of the food storage space 76 or 77 are exclusively conveyed. But it is also possible to change the memory half during pivoting, it is pumped in this case, the content of both halves quasi simultaneously through the mouthpiece. Figures 35A to 35G illustrate this. 35A illustrates a predetermined position of the pump top 27 relative to the position of the pump base 29. The pump bottom is shown in FIGS. 35B to 35D. The two images at the ends of the double arrow belong together and each represent an end position of a pivoting operation, ie a rotation of the pump lower part 29 against the pump upper part 27 assumed to be fixed. In these figures, the intermediate wall 75 ', which actually belongs to the pump top, as a dashed vertical line shown.

Fig. 35B illustrates a swivel range in which only a left half 2a of the food storage space is conveyed. In the illustration of FIG. 35C, only a right-hand half 2b is conveyed, and FIG. 35D illustrates the process of simultaneously conveying both storage areas simultaneously.

The embodiment of the invention is not limited to the examples described, but also in a variety of modifications possible, which are within the meaningful and professional action.
