Another embodiment of the dispensing device is characterized in that the second and third female parts consist of holes in the heating device, which holes are preferably disposed entirely or partially in a hot plate which is a component of the heating device.

Yet another embodiment of the dispensing device is characterized in that a magazine in which the food container can be placed comprises a fastening and supporting part for fastening and supporting of the first female part disposed in the food container when the magazine is moved in the direction of the first male part on the pumping device.

A further embodiment of the dispensing device is characterized in that the fastening and supporting part is a wall portion of the magazine, which wall portion comprises a groove in which portions of the food container can be inserted with the first female part situated on an outer surface around the wall portion.

A further embodiment of the dispensing device is characterized in that a control device is disposed to guide the magazine during its movement toward said first male part.

In yet another embodiment of the dispensing device it is characterized in that the heating device comprises at least one non-rectilinear channel system through which the food is taken for its heating, the channel system being preferably meandering in form.

One embodiment of the dispensing device is characterized in that the heating device comprises a heatable hot plate, which preferably consists of aluminum, and which comprises a channel system for the food, which channel system is configured as grooves in a surface of the hot plate, and the surface of the hot plate with the grooves lies tightly from above against a bottom plate and is connected to it by means of quick coupling elements for quick connecting and disconnecting of the latter.

Yet another embodiment of the dispensing device is characterized in that a heating plate is disposed above the hot plate for warming up the hot plate and an electrical system is disposed for the warming up.

Another embodiment of the dispensing device is characterized in that between the hot plate and the bottom plate is disposed a seal in the form of a compressible disk, e.g., made of rubber, preferably silicone rubber, which is configured to cover at least the entire bottom plate in order to prevent leakage of the food between individual loops of the groove and between the hot plate and the bottom plate, but also to the surroundings. The rubber sealing disk is detachable.

According to another aspect of the invention, the benefits/effects mentioned above and below are achieved by means of a method for producing an air-tight and quickly assembled and disassembled dispensing system for a dispensing device for dispensing of liquid food, preferably peanut sauce, from a food container which collapses when the food is suctioned out from it, wherein the food is suctioned out from the food container by a pumping device which dispenses the food from the dispensing device via a check valve and wherein the food is heated up in a heating device, characterized in that the food container and the pumping device are quick-coupled air-tight to each other in a plug-like manner to form a connection between them, which is also quickly dismountable, the pumping device and the check valve are quick-coupled air-tight in a plug-like manner to the heating device by utilizing coupling parts arranged in or on the latter in the form of female parts, the heating device and the check valve are tightly quick-coupled to each other in a plug-like manner to form a connection between them which is also quickly dismountable, and the quick couplings are done manually and without tools.

Thanks to the above solution, an air-tight dispensing system is achieved which is suitable for the handling of air-sensitive foods and whose parts can be quickly and easily assembled and disassembled. By means of at least one of the above solutions one achieves a better, but also a more exact heating of the food. At least one solution above also allows a more effective utilization of the available area for the surface which warms up the food. At least one of the solutions above furthermore provides a better oxygen barrier between the food being warmed up and the surroundings since the bearing surface for the seal between parts in the heating device is further increased. The increased bearing/sealing surface also means better leakage protection inside the heating device, including between individual heating parts, such as groove and channels through which the food is taken, but also against the surroundings. The larger bearing/sealing surface is achieved by a surface-covering sealing layer of insulating material, preferably rubber, such as silicone rubber, which means a better heat leakage protection within the heating device and between individual heating parts, such as between bottom part and parts lying in between, such as hot plate, and also against the surroundings.

DESCRIPTION OF EMBODIMENTS The dispensing device 1 shown in Fig. 1 to 7 is intended for dispensing of liquid food 2 from a food container 3. The liquid food 2 is preferably of the air-sensitive type, such as peanut sauce, but it can be of a different type, such as sauce or dressing, mustard, ketchup or a beverage. The food container 3 consists of a material having the ability to collapse when the food 3 is suctioned out from it and this material is preferably a plastic with barrier properties which guarantee that the food 3 can be kept in it air-tight and thus for a lengthy time without risk of bacterial attack.

For the suctioning of the food 2 from the food container 3 and the dispensing of it from the dispensing device 1 there is a pumping device 4. This is advisedly hand-operated and can be of any previously known type, such as the type appearing in document SE 1300164 (Al), but it can also be motor/electrically operated. For the warming up of said food 2, there is a heating device 5 located in its flow direction S after the pumping device 4 and after this there is situated a check valve 6, which is designed to open in order to release the food 2, which is pumped by means of the pumping device 4 into it, and to close when this flow ceases. The purpose of the check valve 6 is thus to prevent air from getting into the dispensing system.

The food container 3 is initially closed entirely. In order to make possible a quick and air-tight coupling to the pumping device 4 and just as easy a disconnection from the latter in order to replace it with a full food container 3, a first air-tight quick coupling 7 is disposed to connect the food container 3 and the pumping device 4 to each other. This quick coupling 7 can be of a previously known type, for example, it can be of the type appearing in said document SE 1300164 (Al). As appears from this document, the quick coupling 7 can comprise a first female part 8, which is disposed inside the food container 3 and comprises a hole 9. Moreover, the quick coupling 7 can comprise a first male part 10 connected to the pumping device 4, which comprises a tube-like part 11 with a first flow channel 12 for the food 2. This tube-like part can have an end margin 13 which is designed to push up a hole in the food container 3 in order to open it before the first male part 10 is forced into the first female part 8 and held firmly against it by means of friction between them. In this way, the food container 3 can be opened and be coupled together with the pumping device 4 by means of the first quick coupling 7.

Said first female part 8 can comprise inner coupling portions 8a and the first male part 10 outer coupling portions 10a ensuring that the first quick coupling 7 remains air-tight and ensuring a frictional engaging with each other. When the food container 3 is empty, it can be disconnected entirely by simply pulling the first female part 8 out from the first male part 10, after which a full food container 3 can be attached in the aforementioned manner.

A second air-tight quick coupling 14 is disposed to connect the pumping device 4 to the heating device 5. In order to couple these together in a quick and air-tight manner and clean them individually apart from each other after use, the second quick coupling 14 comprises a second male part 15 and a second female part 16.

The second male part 15 is disposed on or connected to the pumping device 4 and it can consist of or comprise a tube-like part 19 with a second flow channel 18 for the flowing of the food 2. The tube-like part 19 can consist of or comprise silicone material. The second female part 16 can be a hole 20 in a portion of the heating device 5 for the receiving of the food 2 and can communicate with a channel system 21 through which the food 2 flows in order to be warmed up. The heating device 5 can be connected to the pumping device 4 by bringing the second male part 15 into engagement with the hole 20 so that said devices 4, 5 sit firmly against each other. In order to produce said fastening, the second male part 15 has outer coupling portions 15a and the second female part 16, i.e., the borehole 20, has inner coupling portions 16a which ensure that the second quick coupling 14 becomes air-tight and maintains its quick coupling position by friction.

When the heating device 5 and/or the pumping device 4 is to be cleaned, they are uncoupled from each other by pulling apart the second male and female parts 15, 16 of the second quick coupling 14.

A third air-tight quick coupling 22 is disposed for quick and air-tight coupling together of the heating device 5 and the check valve 6 and easy disconnecting of these for separate cleaning thereof. This third quick coupling 22 comprises a third male part 23, which can be composed of a rear tube-like part 24 of the check valve 6 with a third flow channel 25 in said tube-like part 24. This third quick coupling 22 furthermore comprises a third female part 26 which can be composed of a hole 27 in the heating device 5, which hole 27 communicates with said channel system 21 for the emptying of the food 2 via the check valve 6.

In order to produce said fastening, the third male part 23 has outer coupling portions 23a and the third female part 26, i.e., the hole 27, has inner coupling portions 26a which ensure that the third quick coupling 20 becomes air-tight and maintains its quick coupling position by friction.

In order to enable separate cleaning of the heating device 5 and the check valve 6, they can be disconnected from each other by pulling apart the third male and female parts 23, 26. Summarizing, it can be said that the three couplings 7, 14 and 22 are plug-like, i.e., they work like plug contacts in that these parts can be inserted one into another and sit firmly against each other by friction between them. Couplings 7, 14 ach 22 are plug contacts.

In order to facilitate quick coupling of the food container 3 and the pumping device 4 to each other, there can be a tubular magazine 28 in which the food container 3 can be placed and which contains a fastening and supporting part 29. On this can be fastened those portions 30 of the food container 3 which are located directly behind its parts 31 in which the first female part 8 is located, so that the female part 8 is situated outside of the fastening and supporting part 29. In this way, the first female part 8 can be held in readiness for coupling to the first male part 10. The fastening and supporting part 29 can be a wall portion 32 of the magazine 28 and this wall portion 32 can have a groove 33 open on top, in which said portions 30 of the food container 3 can be inserted.

By moving the magazine 28 in the direction R of the first male part 10 until the wall of the food container 3 at the first female part 8 comes into contact with the end margin 13 of the first male part 10, the latter will open the food container 3 by pressing a hole in said wall, while the fastening and supporting part 29 constitutes an abutment for the first female part 8 during this coupling maneuver.

There can be a control device 34 to guide the movement of the magazine 28 in the direction R of the first male part 10 and thereby facilitate the coupling torque. This control device 34 can comprise two control elements 35, e.g., guide rails between which the magazine 28 is movably arranged.

The heating device 5 can comprise a heatable hot plate 36 which can have the channel system 21 in which the food 2 is warmed up. The hot plate 36 consists preferably of aluminum and the channel system 21 preferably has a meandering form in order for the food 2 to be in contact with the hot plate 36 for the required length of time. The channel system 21 can be configured as one or more grooves 37 in a surface 38 of the hot plate 36 and this surface 38 can be facing downward and lie tightly from above against a bottom plate 39 (see Fig. 3-5), preferably one made of aluminum, or it can be facing upward and lie tightly from underneath against the bottom plate 39 (see Fig. 2, 6 and 7). This tight abutment can be achieved with the aid of a sealing element 40, such as a silicone strip, as in Fig. 2, or a thin silicone rubber plate/disk as in Fig. 5 and 7. The rubber plate 40 constitutes a thin layer between bottom plate 39 and hot plate 36 and acts as a sealing surface between bottom plate, hot plate, and food, in order to prevent leakage thereof. Figures 5 and 7 also show guides which help hold the sealing plate 40 in place sideways during the removable mounting of the latter between the bottom plate 39 and the hot plate 36. The groove 37 is preferably a contiguous channel with several loops.

Figure 2 shows a meander form for the channel system 21 and figure 7 shows another meander form with deeper groove 37 for the channel system. The meander form in figure 7 is laid out with a tighter pattern and more bends along the meandering groove 37 as compared to figure 2 and provides further improved heat exchange with the food 2 and more effective utilization of available area for the surface 38. A deeper groove 37 also makes possible a greater flow of the food 2. Thanks to a disk-like compressible seal in the form of the rubber plate 40, an improved oxygen barrier is achieved between the food 2 and the surroundings, since the bearing surface between bottom plate 39 and hot plate 36 is further increased. The rubber plate 40 covers more than the entire bottom plate 39. The rubber plate 40 covers both the surface of the bottom plate 39 and parts of the surface of the hot plate 36. The rubber plate 40 covers the entire bottom plate 39 so that the bottom plate is not in direct physical contact by any part with the hot plate 36. The bottom plate 39 is rigidly formed so as to provide good support and resistance to the internal pressure in the channel system 21. The increased bearing/sealing surface thanks to the surface-covering rubber disk 40 in Fig. 3 to 7 means a better leakage protection within the heating device, including individual heating parts such as parts between channels in the groove 37, and also to the surroundings of the food. The increased bearing/sealing surface thanks to the surface-covering sealing layer 40 of insulating material, preferably silicone rubber, means a better protection against leakage of heat within the heating device 5, but also between individual heating parts, such as between bottom part 39 and hot plate 36 as well as other or intermediate parts, such as between single or individual loops of the channel 37, and also to the surroundings. This means that the bottom part 39, which also functions as a planar bottom cap over the rubber plate 40, is well insulated against the heat inside the hot plate 36. The rubber plate 40 also reduces heat loss, including through the bottom cap 39.

On top of the hot plate 36 there can be placed a heating plate 41, whose bottom side has contact with the top side of the hot plate 36 so that an effective heat transfer is achieved between the plates 36, 41. The heating plate 41 can also preferably consist of aluminum and this can have a hole 42 for a heating rod 43 for electric heating of the heating device 5. The heating rod 43 can be integrated in the heating plate 41. An electrical system 44 for said heating can be disposed on top of the heating plate 41 or also be integrated in the heating plate 41, but with operatively accessible connections for power supply.

The hot plate 36 and the bottom plate 39 and optionally also the heating plate 41 are preferably held together with quick coupling elements 45, such as screws with wing nuts or the like, so that they can be quickly released from each other by disassembly for cleaning of the channel system 21 and then be quickly reassembled. The rubber plate 40 with its surface coverage also insulates well against heat loss through the screw grommets for the quick coupling elements 45, and also through the check valve 6. The rubber plate 40 is made of silicone rubber, for example, with a Shore hardness 40. The above described device enables a method of manual and air-tight quick coupling without tools between the food container 3, the pumping device 4, between the pumping device 4 and the heating device 5 and between the heating device and the check valve 6. In this way, one can achieve an entirely air-tight dispensing system, which is essential for the handling of sensitive foods 2. Furthermore, one obtains an air-tight system which is easily and quickly taken apart, as the different parts need to be cleaned, which should be done often and easily in order to maintain good hygiene in the handling of foods, especially foods of sensitive type.

The above described invention can vary in its execution within the scope of the following patent claims, for example, the food container 3 can also have the shape of a plastic bag and the check valve 6 can consist entirely or partially of silicone material. The pumping device 4 is of air-tight type and can be cleaned as a single piece. The first male part 8 and/or the second male part 15 can be directly or indirectly connected to the pumping device 4. Moreover, the different plates 36, 39 of the heating device 5 can be rectangular and preferably of the same size. The hole 27, forming the third female part 26, can be disposed in the hot plate 36 and/or in the bottom plate 39/rubber plate 40/protrusion 46. The hole 27 has the purpose of emptying the food 2 arriving from the entry hole 20 via the outlet of the check valve 6. It can be said that the food container 3 with the food 2 preferably has room temperature, while the food 2 after the heating can have a temperature of around 65° C and the heating of the food is done "just-in-time". Finally, it can be said that the cleaning of the various parts preferably means dishwashing. The bottom plate 39 and the rubber sealing plate 40 have grommets for the thumbscrews 45, i.e., there is a through hole in the bottom plate and the rubber plate and a corresponding threaded hole in the hot plate through which the food 2 is taken.

The check valve 6 functions as a mouthpiece for emptying/portioning/dispensing and is primarily cylindrically shaped or cylindrical. The check valve 6 is pressed onto a protrusion 46 (see middle view in figure 7) or a tap and is held in place on the protrusion by a snap function or friction or a bayonet mount/bolting. The protrusion 46 is primarily cylindrically shaped or cylindrical, but it can have a convex or concave or conical form or have a form which is a combination of at least partly convex and/or concave and/or conical surfaces. The protrusion 46 comprises one or more holes 27 or one or more openings disposed on its envelope surface with its hole opening pointing essentially radially or radially in the envelope surface, i.e., to the side or sideways. This means that the food 2 can be emptied from the channel system 21 and through the protrusion 46 in its longitudinal direction, then radially out to the side of the protrusion then through the check valve 6 and out through its outlet. The rubber plate 40 with its surface coverage offers good insulation against heat loss through the protrusion 46 and also out through the check valve 6. The protrusion 46 in one embodiment is an integrated part of the rubber plate 40. The protrusion 46 in another embodiment is a cast part in the rubber plate 40. In yet another embodiment, the protrusion 46 is one and the same as the rubber plate 40. In yet another embodiment, the protrusion 46 is a part cast together with the rubber plate 40. In another embodiment, the protrusion 46 is attached by adhesion on/in the plate 40.
