Description

[0001] The present invention relates to the field of wet pet food bags, typically for small pets, such as cats or dogs. Wet food includes (but is not limited to) French pate food. The present invention also relates to an assembly comprising such a wet food bag and a device for dispensing food, in which the bag is mounted.

[0002] In the field of devices for dispensing pet food, food receptacles that control the animal's access to wet food are known. For example, the solution of the prior art is to equip the animal (e.g., a cat) with a microchip, which is usually worn on a collar around the animal's neck or via an intradermal chip. The receptacle is, for example, equipped with a removable lid that prevents access to food when closed. The receptacle is equipped with an electronic control device for opening the lid, and a chip identification device (e.g., a detection ring) connected to the control device. In this way, an animal equipped with a chip and approaching the receptacle controls the opening of the lid, thereby freely obtaining wet food. However, the disadvantage of this type of receptacle is that it needs to be manually refilled by the user each time the food is dispensed. In addition, once the wet food is taken out of its packaging, it will oxidize within about four to eight hours, even when protected from ambient air.

[0003] Therefore, it is necessary to be able to automatically and repeatedly dispense wet food (such as French pate), so that users can more easily handle their own affairs while meeting the nutritional needs of animals. For this purpose, a dispenser that automatically delivers a predetermined dose of wet food is known. For example, patent 9 232 769 B1 discloses such a wet food dispenser. The dispenser includes a food dispensing unit and several wet food bags arranged in the upper part of the unit. The food dispensing unit is provided with a housing, a storage container arranged in the lower part of the housing; an electromechanical device, which is arranged in the middle part of the housing, for supplying food from the bag to the storage container; and a device for controlling the electromechanical device. Each bag is attached to the housing from the top and bottom via top and bottom fixing clips arranged on the housing. The electromechanical device includes a servomotor equipped with a shaft, which is in turn connected to a belt / pulley system. The belt is connected to a movable arm via a connector, which passes through a channel in the housing. Therefore, the arm equipped with a rotating blade at its free end is driven to translate along the channel by the action of the motorized belt / pulley system. In operation, the arm with its blade cuts through one end of the bag pre-positioned on the housing so that the wet food can be dispensed into the receptacle. However, the disadvantage of the food dispenser disclosed in the patent patent document is that it requires the consumption of a whole bag of wet food for each dose of food dispensed. This leads to food waste and overconsumption by the animals and undermines the autonomy of the device. Another disadvantage of this dispenser is that it does not guarantee bacterial and antioxidant protection for the wet food. This is because the food container and the opening mechanism, and even the bag itself, once opened, are still in contact with air carrying microorganisms and bacteria, which are sources of bacterial contamination.

[0004] It is therefore an object of the present invention to provide a wet pet food bag which makes it possible to meter a precise amount of wet food suitable for the animal and which ensures a controlled and steady flow of the wet food from the bag.

[0005] Another object of the present invention is to provide a wet pet food pouch that provides for bacterial and antioxidant protection of the wet food.

[0006] To achieve these objectives, according to a first aspect, the invention proposes a wet pet food bag intended to be compressed by squeezing and / or pressing the bag's components to ensure automatic release of at least a portion of its contents, the bag being formed by two walls connected to each other on a portion of their periphery and defining between them a volume for containing wet food, the two walls not connected to each other on another portion of their periphery to form a neck for opening the bag, the neck being deformable between at least one open position and one closed position; the bag's walls comprising, on their internal faces, one or more internal welds connecting the walls to each other within the bag, the internal welds being connected to each other to form within the bag a funnel in fluid communication with the open neck of the bag.

[0007] According to the present invention,

[0008] the open neck comprises a continuous lip which is separable from one another to define an opening of the bag for the passage of a portion of its contents, the lip forming a sealing barrier when tension is applied thereto by exerting a pulling force on at least one of the bag portions located transversely to the open neck,

[0009] the neck is configured to present straight cross sections of different shapes for at least two different opening positions thereof, one of the opening positions being called "forced" and corresponding to a circular or substantially circular straight cross section of the neck when a thrust is exerted on the neck, and

[0010] - when the neck allows the wet food to pass through and when it is at rest, ie not under tension,

[0011] The ratio between the width (LG) and the height (HG) of the neck is between 1.5 and 10, preferably between 2 and 4, and even more preferably equal to 2.5, in order to ensure a regular flow of the wet food through the neck.

[0012] Advantageously, the neck of the bag disclosed above has technical features that ensure smooth flow of its contents during use or adoption of the device disclosed above for dispensing wet food. This avoids, for example, the formation of jets of wet food, making it impossible to control the amount of wet food dispensed.

[0013] The bag also features at least two "stable opening geometries or shapes" to allow for adjustment of the rheology and / or number of phases of the wet food contained therein.

[0014] A "stable opening geometry or shape" of a bag neck means that the configuration of the bag neck remains stable over time when constant tension is applied to the portions of the bag flanking the open neck, or conversely in the absence of such tension.

[0015] By way of illustration only, a first of the opening positions corresponding to the stable opening geometry of the neck, the so-called forced opening position, corresponds to the position of the or each block of a wet food dispensing unit with which the bag is intended to be used, wherein the block pushes on a corresponding portion of the bag arranged transversely to the neck.

[0016] To exert this push, the corresponding block is moved towards the neck.

[0017] The forced open position corresponds, for example, to a "fully open" neck geometry and to a circular or substantially circular straight neck cross-section, the latter being reached when the at least one block is positioned closest to the neck.

[0018] According to another description, another of the opening positions corresponding to the stable opening geometry of the neck, called the normal opening position of the bag, corresponds to the position of the block or each block, wherein the corresponding part of the bag arranged transversely to the neck is not tensioned by the block.

[0019] For example, the stable opening position corresponds to a neck opening geometry, wherein the neck has a straight cat's eye cross-section.

[0020] In addition, this funnel-shaped configuration enables the wet food to be effectively and fluidly directed toward the bottom of the bag, and in particular toward the neck having a narrower diameter. This ensures a controlled, stable flow of wet food from the neck. In addition, since the neck is deformable between an open position and a closed position, the interior of the neck (and therefore the interior of the bag) remains airtight outside the wet food dispensing period due to the closure of the neck. The contents of the opened bag remain airtight and antibacterial, because the opening surface of the bottleneck is minimal, almost always sealed, without residues (which fall due to gravity). This guarantees effective bacterial and antioxidant protection for wet food. It should also be noted that the bag according to the invention does not have a liner, a stopper or a moving attachment, nor does it have any residues on the outside; nor does it have any suction to draw air from the bag: the food is pushed out of the bag, or remains in the bag. The constant upright position of the bag also means that the wet food closes the neck opening and prevents air from entering.

[0021] Advantageously, the neck is configured to be selectively opened or closed by pushing or pulling on at least one edge of the bag or on a portion of the bag located transversely to the open neck.

[0022] This pushing or pulling can be performed, for example, by motorized gripping elements of the portion of the bag placed transversely to the open neck.

[0023] According to an embodiment of the wet pet food bag, the ratio between the height of the funnel (HE) and the width of the neck (LG) is greater than 1.5 and preferably greater than 2 when the neck allows the wet food to pass through and when it is at rest (ie not under tension).

[0024] According to another embodiment of the wet pet food pouch, the width of the neck (LG) is between 1.5 cm and 5 cm, and the height of the neck (HG) is between 0.5 cm and 3 cm.

[0025] According to yet another embodiment of the wet pet food bag, the open neck is formed at the other opening position thereof to have a substantially oval or eye-shaped straight cross section.

[0026] According to yet another embodiment of the wet pet food bag, the wet pet food bag includes a valve in the shape of a nipple or duckbill mounted on a neck thereof.

[0027] According to yet another embodiment of the wet pet food bag, each wall is formed of at least two layers and includes at least one inner sheet designed to define a portion of the wet food holding volume made of food compatible material and an outermost layer formed of a film that blocks or absorbs ultraviolet rays.

[0028] According to another embodiment of the wet pet food bag, the wall of the bag is made of a metal material made of aluminum or an aluminum-based alloy, or a plastic material made of polypropylene. The use of this polypropylene material ensures that the bag can be recycled.

[0029] By way of illustration, the bag is made of a single plastic material, such as a thermoplastic, advantageously a polyolefin, such as polypropylene (PP).

[0030] According to yet another embodiment of the wet pet food bag, when laid flat when empty, the wet pet food bag has a generally rectangular or pointed shape, or a diamond shape, in its lower part, and the walls of the bag include at least two internal welds connecting the walls to each other on their inner faces in the area of ​​the wet food holding volume within the bag.

[0031] Preferably, these internal welds are arranged to form a "V" or "U" shape, the internal welds preferably being arranged symmetrically around a median longitudinal plane of the bag.

[0032] Advantageously, each of these welds extends from a corresponding side edge of the bag to the neck, leaving the portion of the wet-food containing volume situated in the upper part of the bag completely free.

[0033] Preferentially, the height h of the free portion (ie the internal weld without walls in the containing volume) is then at least equal to 75% of the height H of the food containing volume of the bag.

[0034] According to yet another embodiment of the wet pet food bag, the wet pet food bag includes two internal welds arranged to form a "V" shape when the bag is laid flat and not filled with wet food, the two internal welds are symmetrically arranged around a middle longitudinal plane of the bag, and each internal weld extends in a direction that forms an angle with a direction corresponding to the length of a rectangle formed by the bag.

[0035] Preferably, each of the angles is between 25 and 35 degrees, preferably substantially equal to 30 degrees.

[0036] According to yet another embodiment of the wet pet food bag, the bag comprises at least two apertures, and even more preferably at least five apertures, placed in the upper portion of the bag and intended to engage with fastening elements to ensure suspension of the bag.

[0037] By way of illustration only, the bag has a generally rectangular shape when laid flat and not filled with wet food, and the bag is provided with four apertures located at the four corners of the rectangle formed by the bag.

[0038] Preferably, the shape of each orifice is selected from the group consisting of a circle, an oval, a shape elongated by bending, an ellipse or a rectangle.

[0039] Advantageously, of the two apertures located at the upper corners of the rectangle formed by the bag, one of the apertures has a rectangular shape, the length of the rectangular aperture being oriented along the width of the rectangle formed by the bag, and the other aperture has a generally triangular shape. The apertures thus configured facilitate mounting and holding the bag in place within the wet food dispensing unit of the device for dispensing food.

[0040] According to yet another embodiment of the wet pet food bag, each upper aperture at an upper corner of the bag is vertically aligned with a corresponding lower aperture at a lower corner of the bag, with a lateral variation of ±1 cm.

[0041] According to yet another embodiment of the wet pet food bag comprising bag portions transverse to and placed on both sides of the neck, the wet pet food bag is provided with at least two additional apertures placed on both sides of the open neck.

[0042] Advantageously, each of the portions of the bag placed transversely to the neck defines a clamping zone whose dimension or width transversely to the bag is between 2 cm and 5 cm, and more preferably between 3 cm and 4 cm, and whose height is between 1 cm and 3 cm, and more preferably equal to about 1 cm.

[0043] According to a second aspect, the invention relates to a device for dispensing pet food, the device comprising a housing comprising a food receptacle and a wet food dispensing unit, the wet food dispensing unit being adapted to accommodate a removable wet food bag, the wet food dispensing unit being configured to ensure retention and attachment of the bag so that the bag then extends at least partially along a main axis, the bag being provided with a neck for opening the bag, the neck being deformable between at least an open position and a closed position, being provided on a lower part of the bag and being arranged to face the food receptacle when the bag is accommodated in the wet food dispensing unit, the wet food dispensing unit comprising:

[0044] - an electromechanical device for supplying wet food from the bag to the food container, and

[0045] - a control device for an electromechanical device capable of controlling the transfer of wet food from the bag to the food container. According to the invention, the electromechanical device comprises:

[0046] - at least one block comprising a gripping element for holding a portion of the bag arranged transversely to the neck, the gripping element being mounted to move in translation along an axis transverse or substantially transverse to the main axis, and a motor for driving the gripping element to shift between a position corresponding to an open position of the neck of the portion of the bag held in this way and a position corresponding to a closed position of the neck for pulling the portion of the bag held in this way,

[0047] when the electromechanical device comprises two blocks, the blocks are configured to hold a first portion and a second portion of the bag placed transversely to the neck and on either side of the neck,

[0049] The blocks, or the block and the retaining element, are configured to allow selective opening or closing of the neck, wherein tensioning the first and second parts in the pulled position ensures tight closure of the neck and thus guarantees bacterial and antioxidant protection of wet food.

[0050] The present disclosure advantageously allows the same bag that has been opened to be kept in a wet food dispensing unit for a longer period of time without changing the quality of its contents. Testing has shown that the same 500 gram bag of wet food (double nutrition) can be used in the food dispenser at room temperature for two (2) to five (5) days after the food dispenser has been opened. There is no need to store the bag in a refrigerator after opening.

[0051] Preferably, the housing comprises a one-piece, die-cast aluminum shell.

[0072] Figures 1 to 3 , Figure 5 and Figure 7 There is shown an assembly 1 comprising an apparatus 2 for dispensing pet food and a wet pet food bag 4 mounted within the apparatus 2. The apparatus 2 is typically designed to dispense food for a small pet, such as a cat or dog.

[0073] The food dispensing device 2 comprises a housing 6 in which are arranged at least one food receptacle 8A, 8B, a wet food dispensing unit 10, a dry food dispensing unit 12, a scale, a data processing unit and a wireless communication device (these latter three elements are not shown in the figure for the sake of clarity). Figures 1 to 4 , Figure 7 , Fig. 9 and Fig.10As shown, the food storage 8A, 8B is arranged in a drawer 14 that is movably mounted in the housing 6, and the food dispensing device 2 also includes means for controlling the movable drawer 14 (not shown in the figure for the sake of clarity). Even more preferably, the food dispensing device 2 also includes a camera 16, which is connected to the data processing unit and is positioned on one side of the housing 6, typically on the front side 18 of the housing 6 (the front side 18 of the housing 6 is defined as the side facing the animal when the animal wishes to eat). Even more preferably, the food dispensing device 2 also includes a light or sound indicator 19 for indicating the operation of the device 2, which is connected to the data processing unit and is positioned on one side of the housing 6, typically on the front side 18 of the housing 6. Even more preferably, the food dispensing device 2 also includes a speaker (not shown in the figure for the sake of clarity), which is connected to the data processing unit and is positioned on one side of the housing 6, typically on the front side 18 of the housing 6. Even more preferably, the food dispensing device 2 further comprises an interface for manually controlling the device 2 (not shown in the figure for the sake of clarity), which is connected to the data processing unit and is positioned on one side of the housing 6, typically on the upper side 20 of the housing 6. The food dispensing device 2 further comprises a series of servomotors and sensors, which will not be disclosed in more detail herein. Figures 1 to 4 as well as Figures 7 to 10 As shown, the housing 6 is advantageously equipped with a door 21 which is pivotally mounted on the housing 6 and which allows access to the interior of the housing 6 when open.

[0074] exist Figure 2 and Figure 4 In the particular embodiment shown, the food dispensing device 2 includes two food receptacles 8A, 8B, namely a first receptacle 8A for containing wet food and a second receptacle 8B for containing dry food. The first food receptacle 8A is arranged opposite to the wet food bag 4. The second food receptacle 8B is arranged opposite to the dry food dispensing unit 12 (the latter is a conventional dry food dispensing unit, which will not be disclosed in more detail below, but includes a dry food storage). Dry food includes (but is not limited to) dry kibble.

[0075] For example, each food storage container 8A, 8B is a removable, interchangeable storage container. The drawer 14 is in the open position (eg Figure 2 and Figure 4 as shown) and the closed position (as Figure 1 , Figure 3 , Figure 7 , Fig. 9 and Fig.10The movable drawer 14 is movably mounted in the housing 6 between the housing 6 and the drawer 14 (shown). In the open position, food can enter from the outside of the housing, and in the closed position, food cannot enter from the outside of the housing 6. The movable drawer 14 is, for example, clamped in an opening in the housing 6. Therefore, the movable drawer 14 can be released from the housing 6 so that the entire drawer 14 can be easily cleaned. The control device of the movable drawer 14 can control the opening or closing of the movable drawer 14. Figure 2 and Figure 4 In the particular embodiment shown, the removable drawer 14 also contains another removable crumb catcher type receptacle 22. This "crumb catcher" type receptacle 22 collects wet food residues that may fall out of the bag 4 when the removable drawer 14 is in its open position, or when the removable drawer 14 is in its translational movement between its open and closed positions. A scale (not shown in the figures), for example an electronic scale connected to a data processing unit, is arranged inside the removable drawer 14. Such a scale is able to accurately measure the weight of each dose of wet food dispensed and the weight of wet food consumed by the animal (by the difference between the weight of the contents of the drawer 14 before and after it has been opened).

[0076] The wet food dispensing unit 10 comprises an electromechanical device 24 for supplying wet food from the bag 4 to the first food storage container 8A; and means for controlling the electromechanical device 24 (not shown in the figure, but for example connected to or including a data processing unit). The control means for the electromechanical device 24 can control the delivery of wet food from the bag 4 to the first food storage container 8A. The wet food includes (but is not limited to) French pate food. Preferably, the wet food dispensing unit 10 also includes means 25 for fastening the upper part of the bag 4 in the housing 6.

[0077] The wet pet food bag 4 is removably mounted in the food dispensing apparatus 2 and is housed in the wet food dispensing unit 10 of the apparatus 2. More specifically, as Figure 2 , Figure 3 , Figure 7 and Figure 8 As can be seen, the wet food bag 4 is held and fastened in the housing 6, in particular via means 25 for fastening the upper part of the bag 4. The bag 4 is provided with a neck 26 for opening the bag 4, which is provided on the lower part of the bag 4. The neck 26 is in the open position (in Fig.14 ) and the closed position (shown in Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig.13) and is arranged opposite to the first food receptacle 8A when the bag 4 is accommodated in the wet food dispensing unit 10. The neck 26 is configured to be selectively opened or closed by pushing or pulling on at least one edge 27A, 27B of the bag 4.

[0078] According to a specific embodiment of the present invention, Figure 2 , Figure 3 and Figures 5 to 8 As shown, the wet food bag 4 is formed by two walls (in particular two substantially rectangular walls) joined together at a portion 28A of their periphery 28 and defining a wet food receiving volume therebetween. Figure 6 As shown, the two walls are not connected to each other at another portion 28B of their periphery 28 and are configured to form a neck 26 for opening the bag 4 at this other portion 28B. The neck 26 is thus composed of two lips, each forming part of a separating wall of the bag, which lips are closed in the open position of the neck 26 (in the Fig.14 The two lips are spaced apart in the closed position of the neck 26 (in Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig.13 ) in contact with each other and extending parallel to each other. Preferably, as Fig.14 As shown, the neck 26 has an eye-shaped cross section in its open position. In a variant not shown, the neck 26 has a substantially circular or oval cross section in its open position.

[0079] The wall of the bag 4 is made of a metal material, for example made of aluminum or an aluminum-based alloy, or of a plastic material, made of polypropylene. The use of such a polypropylene material ensures that the bag 4 is recyclable. The wall of the bag 4 comprises one or more internal welds 30 in its interior, which connect the walls to each other in the bag 4. Preferably, as Figure 6 As shown, the wall of the bag 4 has two internal welds 30 on its internal face, which connect the walls to each other inside the bag 4, and when the bag 4 is laid flat and not filled with wet food, the two internal welds 30 are arranged to form a "V" shape. The two internal welds 30 have a symmetrical arrangement around the middle longitudinal plane of the bag (such a plane is a vertical plane extending perpendicular to the extension plane of the rectangle formed by the bag when there is no food), and each internal weld 30 extends in a direction D1, D2, which forms an angle a1, a2 with the direction corresponding to the length of the rectangle formed by the bag when there is no food (this direction is also a vertical direction). Preferably, and as Figure 6As shown, each of the angles a1, a2 is between 25 and 35 degrees, preferably substantially equal to 30 degrees. The internal welds 30 are interconnected to form a funnel 32 inside the bag 4, which is in fluid communication with the neck 26 of the bag 4. This funnel shape enables the wet food to be effectively and fluidly directed toward the bottom of the bag 4, and in particular toward the neck 26 having a narrower diameter. This ensures a controlled, stable flow of the wet food from the neck 26, regardless of the descending height of the rollers 36A, 36B (see below) relative to the bag 4.

[0080] like Figure 6 As shown, the wet food bag 4 is provided with four apertures 34A, 34B, 34C, 34D so that it can be fastened within the wet food dispensing unit 10 within the housing 6. The four apertures 34A, 34B, 34C, 34D are positioned at the four corners of the rectangle formed by the bag 4 when the bag 4 is laid flat and without food. Two first "top" apertures 34A, 34B are positioned at the top corners of the rectangle formed by the bag 4. One of these apertures 34A has a rectangular shape, the length of which is oriented along the width of the rectangle formed by the bag 4. The other aperture 34B, located at the upper corner of the rectangle formed by the bag 4, is roughly triangular in shape. Two further "lower" apertures 34C, 34D, which are generally circular in shape, are positioned at the lower corners of the rectangle formed by the bag 4. Preferably, as Figure 6 As shown, each upper aperture 34A, 34B is vertically aligned with a corresponding lower aperture 34C, 34D, with a lateral variation of ±1 cm. Each lower aperture 34C, 34D is spaced from the edge of the neck 26 by a distance of, for example, between 2.5 cm and 5.5 cm, preferably substantially equal to 4 cm.

[0081] Preferably, in particular Figure 3 , Figure 5 and Figure 6 As can be seen, the wet food bag 4 is provided on its lower part with a seal 35 to protect the neck 26, which protrudes downwards under the neck 26. Before the bag 4 is used, the protective seal 35 hermetically seals the neck 26, thereby preventing any loss of food before it is placed in the device 2. Figure 7 , Figure 8 , Fig.13 and Fig.14 The bag 4 is shown used in an apparatus 2 (for dispensing wet food) with the seal 35 previously removed by the user to enable the neck 26 to function. The seal 35 is advantageously pre-cut to facilitate tearing by the user.

[0082] For example, after the bag 4 has been opened and the seal 35 has been torn off, the neck 26 has a length between 16 mm and 24 mm, preferably approximately 20 mm. For example, the neck 26 has a width in its closed position of between 16 mm and 24 mm, preferably approximately equal to 20 mm, the width being measured in the thickness direction of the bag 4.

[0083] As another example, when the neck 26 has a substantially circular cross section in its open position, the diameter of the neck 26 is, for example, between 11 mm and 15 mm, preferably substantially equal to 13 mm.

[0084] The electromechanical device 24 comprises means 36A, 36B for squeezing and / or pressing the bag 4 and means 38 for clamping at least one edge 27A, 27B of the bag 4. The electromechanical device 24 also comprises at least one motor or servomotor 40, for example an electric servomotor 40, which is connected to the clamping means 38 so as to enable actuation thereof. Preferably, when the squeezing and / or pressing means 36A, 36B are rollers (see below), the electromechanical device 24 also comprises two parts 42 supporting the rollers 36A, 36B and another motor or servomotor (not shown in the figure) connected to the rollers 36A, 36B so as to enable actuation thereof.

[0085] The clamping device 38 is mounted so that it can be pushed toward the position of the neck 26 at one of the edges 27A of the bag 4 (this position corresponds to the open position of the neck 26 and Fig.14 ) and the edge 27A of the bag 4 is pulled away from the position of the neck 26 (which corresponds to the closed position of the neck 26 and is in Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig.13 Thus, the clamping device 38 is configured to selectively open or close the neck 26 of the bag 4.

[0086] exist Figures 1 to 14In the particular embodiment shown, the clamping device 38 is a device for clamping two opposite bottom edges 27A, 27B of the bag 4 and is composed of two clamps 38A, 38B. Each clamp 38A, 38B includes two blades, one of which is pivotally mounted relative to the other blade (for example, by a hinge). Each clamp 38A, 38B is configured to clamp one of the lower edges 27A, 27B of the bag 4. Therefore, when the bag 4 is held by the clamps 38A, 38B, the two clamps 38A, 38B are arranged on both sides of the neck 26 of the bag 4. At least one of the two clamps 38A, 38B is connected to an electric servomotor 40 (in the example shown in the figure, the first clamp 38A is connected to the electric servomotor 40). The first clamp 38A is thus mounted for horizontal translation between a position in which the edge 27A of the bag 4 is pushed towards the neck 26 and a position in which the edge 27A of the bag 4 is pulled away from the neck 26, the translation movement of the first clamp 38A being substantially in the same plane as the plane of extension of the bag 4 when it is empty of food. Figure 3 , Figure 8 , Fig.10 and Fig.11 As shown, each clamp 38A, 38B is provided with a pin 44A, 44B, for example, on the inner face of one of its blades, which is designed to be inserted into one of the lower orifices 34C, 34D of the bag 4, so as to enable the bag 4 to be effectively positioned and retained in the clamp 38A, 38B (the lower orifice 34C, 34D being located on the lower edge 27B, 27A of the bag 4 retained by the clamp 38A, 38B in question). Preferably, each clamp 38A, 38B is provided with means 46 for locking the bag 4 in place in the clamp 38A, 38B, such as a latch for locking the blades of the clamp.

[0087] exist Figures 1 to 14 In the particular exemplary embodiment shown, the means 36A, 36B for squeezing and / or pressing the bag 4 comprises two motorized parallel rollers. Each roller 36A, 36B extends in a direction transverse to (preferably perpendicular to) the vertical direction. The bag 4 extends between the rollers 36A, 36B and is held by squeezing between the rollers 36A, 36B, with the neck 26 of the bag 4 extending below the rollers 36A, 36B, facing the first food storage container 8A. When in the squeezing position of the bag 4, the two parallel rollers 36A, 36B extend in the same horizontal plane. The motorization of the two rollers 36A, 36B, for example, via Figures 8 to 12The following arrangement shown in is achieved: the ends of each roller 36A, 36B are housed in two supports 42, each of which is mounted for vertical translation on a vertical track 48. The two supports 42 are connected to each other via a horizontal crossbar 50 extending behind the rollers 36A, 36B, and each support 42 extends in front of the horizontal crossbar 50. The horizontal crossbar 50 has a central opening 52 through which a vertical auger 54 can pass. The auger 54 is mechanically connected to the above-mentioned servomotor shaft together with the rollers 36A, 36B. The size of the opening 52 is designed to match the diameter of the auger 54 and has a thread so that its internal thread engages with the thread of the auger 54. In this way, when the servomotor is activated, it rotates the auger 54, which in turn vertically translates the assembly including the horizontal crossbar 50, the support member 42 and the rollers 36A, 36B, and the vertical translation movement is performed along the vertical track 48.

[0088] like Fig.12 As shown, each support member 42 includes a first portion 56 for holding one of the two rollers 36A and a second portion 58 for holding the other roller 36B. Each support member 42 extends in a generally vertical plane. The first portion 56 of the support member 42 is configured to form a pivot connection for the roller 36A it holds. Fig.12 As shown, the first portion 56 of the member 42 consists, for example, of a circular aperture into which one end of the first roller 36A is inserted. The second portion 58 of the member 42 is provided with a rectangular recess 60 configured to accommodate the second roller 36B in the first portion 60A of the recess 60 (corresponding to the position where the rollers 36A, 36B are brought together) or in the second portion 60B of the recess 60 (corresponding to the position where the rollers 36A, 36B are moved apart) according to the translational movement of the rollers 36A, 36B in the housing 6. Thus, when downward pressure is exerted on the support member 42 (to push the wet food down the bag 4), for example via the action of a servo motor on the auger 54, the second roller 36B moves upward from the second portion 60B of the recess 60 into the first portion 60A of the recess 60. This movement brings the second roller 36B closer to the first roller 36A. In the absence of pressure applied to the support member 42, the second roller 36B falls back into the second portion 60B of the recess 60, causing the rollers 36A, 36B to move apart. The first portion 60A and the second portion 60B of the rectangular recess 60 are offset vertically and horizontally from each other. The length of the rectangular recess 60 can advantageously be oriented along an axis D3 inclined to the vertical direction, in particular along an axis D3 that forms an angle a3 with the vertical direction between 15 and 45 degrees, for example approximately equal to 20 degrees. For example, each support member 42 is made of plastic material.

[0089] In the particular embodiment shown in the figures, each of the two rollers 36A, 36B is preferably rotatably mounted about its main axis of extension in each of the two support members 42. Each of the two rollers 36A, 36B is, for example, mounted to rotate freely about a rod which in turn is inserted in each of the two support members 42.

[0090] The means 36A, 36B for squeezing and / or pressing the bag 4 enable the bag 4 to be squeezed so that the wet food contained therein gradually sinks to the bottom of the bag, thus exerting pressure on the neck 26 of the bag 4 to ensure a good and controlled flow of the wet food when the neck 26 is in its open position. A linear regression law may advantageously be implemented in the data processing unit to control the movement (profile, speed, pressure, height of lowering, etc.) of the rollers 36A, 36B so as to control the flow of the wet food and the uniform distribution of the doses, regardless of the position of the rollers 36A, 36B. Therefore, the wet food dispensing unit 10 is equipped with at least one sensor (connected to the data processing unit and not shown in the figures) for measuring the vertical position of the rollers 36A, 36B. A slight upward and downward movement of the rollers 36A, 36B (over a very small length compared to the total descent range of the rollers 36A, 36B) may be performed by the control means after each delivery of a dose of wet food. This creates a little slack at the top of the bag 4 to facilitate the subsequent dispensing of the wet food. The means 38 for clamping at least one edge 27A, 27B of the bag 4 are used to control the opening and closing of the bag 4. Due to the specific configuration of the wet food bag 4 (and in particular its deformable neck 26), in combination with the presence of the means 36A, 36B for squeezing and / or pressing the bag 4 and the means 38 for clamping at least one edge 27A, 27B of the bag 4 in the electromechanical device 24, the food dispensing device 2 according to the invention thus makes it possible to meter precise amounts of wet food suitable for an animal (and in particular to deliver precise individualized doses of food, typically doses of wet food in the range of 10 g to 100 g).

[0091] The means 38 for clamping at least one edge 27A, 27B of the bag 4 thus ensures a hermetic (and airtight) closing of the bag 4 when the device 2 is not used by an animal (and in particular when no animal has been identified by the data processing unit - see below). As a result, due to the sealing of the neck 26, the interior of the neck 26 (and therefore the interior of the bag 4) remains airtight outside the wet food dispensing period. The contents of the opened bag 4 thus remain airtight and germ-proof throughout the emptying process, since the opening surface of the neck 26 is minimal, almost always sealed, free of residues (which fall due to gravity) and within a completely closed machine (no contact with pets or insects). This guarantees an effective bacterial and antioxidant protection of the wet food.

[0092] In the particular embodiment shown in the figures, the means 25 for fastening the upper part of the bag 4 inside the housing 6 consist of a jaw attached in the housing 6. The jaw 25 extends over substantially the entire width of the rectangle formed by the bag 4 and comprises two blades, one of which is pivotally mounted relative to the other (for example by a hinge). The jaw 25 is configured to squeeze (or clamp) the upper part of the bag 4 over substantially the entire width of the bag. The jaw 25 is preferentially coated on one or more of its faces in contact with the bag 4 with a rubber strip (not visible in the figures) defining, for example, a serrated tangle (not shown) to facilitate squeezing of the bag 4 by the jaw 25.

[0093] like Figure 3 , Figure 8 and Fig.11 As shown, the jaw 25 is provided with two pins 62A, 62B, for example, on the inner face of one of its blades, which are designed to be inserted into the two upper orifices 34A, 34B of the bag 4, respectively, so that the bag 4 can be effectively positioned and retained in the jaw 25. For example, two openings corresponding in shape to the pins 62A, 62B (and the two upper orifices 34A, 34B of the bag 4) are provided on the outer blades of the jaw 25 to allow these pins 62A, 62B to pass through when the jaw 25 is closed. Preferably, the jaw 25 has at least one (and advantageously two in the exemplary embodiment shown in the figures) device 66 for locking the bag 4 in place in the jaw 25, such as a latch for locking the blades of the jaw 25.

[0094] The data processing unit is connected to the control means of the electromechanical device 24 and to the control means of the movable drawer 14. Alternatively, the data processing unit constitutes the control means. The data processing unit is also connected to the wireless communication means. The data processing unit comprises storage means storing the neural network. The neural network has previously been trained using training data, the training data comprising data from at least one database containing images of animals (usually images of cats). In this way, the data processing unit is able to detect the presence of an animal of a predetermined type (e.g. a "cat" type) in front of the food dispensing device 2 (in particular by obesity detection via the camera 16) and thus initiate a food supply sequence. Preferably, the data processing unit is configured in such a way that whenever the neural network recognizes an animal that is in the field of view of the camera 16 and corresponds to an animal of the predetermined type, the data processing unit stores a photograph of the animal (taken by the camera 16) in its storage means. Recording such a photograph makes it possible to first inform the pet owner that the pet has been recognized by the device 2 and that the device 2 has therefore triggered the food dispensing. In a second stage, anonymous photographs of the animals can be used to provide training data to the neural network.

[0095] The data processing unit is implemented, for example, in the form of a microcontroller or a printed circuit board (PCB) in which firmware is integrated. The firmware is equipped with an artificial intelligence module that stores a neural network, for example.

[0096] The wireless communication means of the device 2 are capable of communicating with a communication device (fixed or mobile) and / or with a remote server, in particular to enable the setting of food doses, manual activation of food dispensing, reporting of various parameters and monitoring of parameters. The wireless communication means of the device 2 are therefore configured to send data to and / or receive data from the mobile communication device and / or the remote server via a wireless network. The communication device is, for example, a smartphone, a tablet or a computer (without limitation), on which a dedicated web application is installed to enable remote control of the device 2 and use of various parameter setting, reporting and parameter monitoring functions.

[0097] The camera 16 is configured to capture an image in front of the housing 6. Preferably, the camera 16 is an infrared camera. For example, the infrared camera 16 is configured to provide a field of view of approximately 120 degrees.

[0098] The method of operation of the food dispensing device 2, and in particular the method of wet food dispensing according to the present invention implemented by the wet food dispensing unit 10 of the device 2, will now be described. Initially, the user of the device 2 places the wet food bag 4 in the wet food dispensing unit 10 so that the neck 26 of the bag 4 extends opposite to the first food receptacle 8A. To this end, the user opens the door 21 of the housing 6, opens the clamps 38A, 38B and the jaws 25, inserts the bag 4 between the rollers 36A, 36B from the bottom to the top, and then adjusts the bag 4 so that the pins 44A, 44B are inserted into the lower orifices 34C, 34D and the pins 62A, 62B are inserted into the upper orifices 34A, 34B. The user then closes the clamps 38A, 38B and the jaws 25, locks the latches 46, 66, and tears the seal 35 off the bag 4. As Fig.13 As shown, the neck 26 of the bag 4 is in its closed position and the means 38 for gripping at least one edge 27A, 27B of the bag 4 is in a position to pull the edge 27A away from the neck 26. The user then closes the door 21. Initially, the drawer 14 is in its closed position (eg, Figure 1 , Figure 3 , Figure 7 , Fig. 9 and Fig.10 shown).

[0099] The wet food dispensing method comprises a subsequent step consisting in activating the control means of the electromechanical device 24 to control the dispensing of the wet food from the bag 4 to the first food receptacle 8A. This activation of the control means is for example carried out manually by the user (either via the manual control interface of the device 2 or remotely via his mobile communication device) or automatically by the data processing unit after the neural network has recognized that an animal corresponding to a predetermined type of animal (e.g. a cat) is present in the field of view of the camera 16. In the latter case, the data processing unit stores the photograph of the animal (taken by the camera 16) in its storage means.

[0100] Activation of the control means of the electromechanical device 24 causes the means 36A, 36B for squeezing and / or pressing the bag 4 and the means 38 for clamping at least one edge 27A, 27B of the bag 4 to move. In particular, at least one of the two clamps 38A, 38B (in this case the first clamp 38A in the example shown in the figures) is in a position to pull the edge 27A of the bag 4 away from the neck 26 ( Fig.13 ) and pushing the edge 27A of the bag 4 toward the position of the neck 26 ( Fig.14 ) between the first and second food receptacles 8A. This movement of the first clamp 38A deforms the neck 26 from its closed position to its open position. The two rollers 36A, 36B then descend vertically in the housing 6 at a vertical descent pitch. The descent length of the rollers 36A, 36B at this vertical descent pitch is predetermined (e.g., via the implementation of a linear regression law in a data processing unit) and corresponds to the dispensing of a predetermined dose of wet food in the first food receptacle 8A. It should be noted that the descent length of the rollers 36A, 36B according to this vertical descent pitch can therefore vary depending on the vertical position of the rollers 36A, 36B in the housing 6.

[0101] Once a predetermined dose of wet food has been dispensed into the first food container 8A (i.e. when the rollers 36A, 36B have completed their vertical downward movement according to the vertical movement pitch), at least one of the two clamps 38A, 38B (in this case, the first clamp 38A in the exemplary embodiment shown in the figure) is in a position to push the edge 27A of the bag 4 towards the neck 26 ( Fig.14 ) and pulling the edge 27A of the bag 4 away from the position of the neck 26 ( Fig.13 ). This movement of the first clamp 38A causes a deformation of the neck 26, which is moved from its open position to its closed position. In addition, the data processing unit activates the control device of the movable drawer 14, which then controls the movable drawer 14 to move toward its open position (as shown in FIG. Figure 2 and Figure 4The animal can then take the dispensed dose of wet food. In an embodiment of the invention where the presence of an animal is automatically recognized in the field of view of the camera 16, each dose of wet food is extracted from the bag 4 only when an animal corresponding to a predetermined type of animal (e.g., a cat) appears in front of the device 2. If the animal does not finish its dose of wet food, the movable drawer 14 closes and the dispensed wet food remains free from oxidation and contamination.

[0102] Dispensing of dry food via the apparatus 2 is not discussed in the context of the method steps detailed above, but such dispensing may of course be via manual control by a user and / or detection of an animal by a neural network, followed by activation of the dry food dispensing unit 12 to deliver a dose of dry food.

[0103] Fig.15 A bag 50 according to another embodiment of the present invention is shown.

[0104] The bag 50 has the following parameters:

[0105] - HU is the "useful height" of the bag, corresponding to the height of the receptacle, measured between the bottom of the top weld of the bag and the top of the neck after the tab has been opened,

[0106] -HL is the free height of the receptacle, measured between the bottom of the top weld of the bag and the start of the internal weld extending away from the side edges

[0107] - HE is the height of the funnel, measured between the start of the internal weld extending away from the side edges of the bag and the bottom of the open rear neck.

[0108] -LG is the width of the neck, measured flat with the bag closed. It is the width, not the diameter.

[0109] -HG is the height of the neck, measured between the height where the inside weld becomes parallel to the edge of the bag and the bottom of the neck after opening.

[0110] -LBS is the width of the solder strip.

[0111] The wet pet food bag 50 advantageously has values ​​within the following ranges:

[0112] -LG between 1.5cm and 5cm

[0113] -HG between 0.5cm and 3cm

[0114] - the LG / HG ratio is between 1.5 and 10, preferably between 2 and 4, and even more preferably equal to 2.5, and

[0115] The HE / LG ratio is greater than 1.5, and preferably greater than 2.

[0116] Advantageously, it can be seen that such values ​​for the construction of a wet pet food bag ensure even distribution of the wet food contained in the bag when the bag is used with the food dispensing apparatus of the present invention.
