Description

DESCRIPTION

Container for receiving animal food

The invention relates to a canned food and a method for filling a container for receiving an animal food, in particular a wet food.

It is known to package animal food, in particular cat food and in particular wet food in cans or aluminum trays, for example, one packaging unit per portion.

Furthermore, it is known for cans in general, but not for food cans, to provide ventilation through the lid. Thus, for example, US 5,439,724 A shows a lid for closing a container, where the lid is held on the container by a vacuum formed in the container. The lid has a pressure relief hole that closes with an adhesive.

Furthermore, US 3,462,037 discloses a lid for a container to be maintained under negative pressure with a wall that is made of a first material and provided with a plurality of openings arranged in a cluster; and a closing element of a second material that is located on one side of the wall in the area of the bundle of openings and comprises a plurality of sections, which are in each case received hermetically in one of the openings, of one of the materials It is elastically deformable, where each of the desired sections of the closure element can be removed from the associated opening by exerting the required retraction force on the closure element to achieve pressure compensation between the container and the ambient atmosphere.

Document FR 2639002 A1 shows a procedure for manufacturing a release container by means of thermoforming. In this regard, a cover is applied to the upper side of a chimney, where removal of the cover allows an entry of air.

DE 201 17501 U shows a portion container for tipping products, such as pudding or the like, in the form of a tub. This has a bottom in which a ventilation opening that is closable and openable from the outside is configured. In the transport state, the ventilation opening is closed with a removable sealing label.

US 4 154345 A shows a thermoplastic container with a ventilation structure to improve the dispensing of food products from the container. In this regard, a deep-drawn projection is provided, which can be pierced with a nail or a fork to create a ventilation in the bottom area of the container.

Documents FR 2639002 A1 and DE 201 17501 U1 show other containers for food products.

However, with prior art animal feed cans it is not possible to extract the entire contents essentially without leaving residue, without the help of tools or without getting, for example, your hands dirty, or transferring the animal feed in such a way. make this possible. In particular, animal feed does not retain its shape when taken out. Furthermore, in current animal feed production processes it is not possible to extract an animal feed pâté with a second component as a coating from a corresponding can, in particular not in a way that results in an attractive product. The use of state-of-the-art cans may not be hygienic, since contact with the animal feed must be established. But, in particular, the known positive properties of wet food in conventional canned food must also be preserved, in particular the high acceptance by the animal, the conservation without refrigeration preferably for at least two years, the stackability and robustness of the packaging, while the packaging must remain easy to open, and the possibility of large-scale production and filling or mass production.

It is an objective of the present invention to avoid or reduce at least one of the aforementioned deficiencies of the state of the art.

This is achieved by a canned food, where an animal food is received in the receiving space of a container for receiving the animal food, where the animal food is composed of two essentially spatially separated components,

• where the container has a bottom surface and a casing surface projecting from a perimeter of the bottom surface, so that the animal feed can be received in the receiving space formed by the bottom surface and the casing surface and It can be emptied through an opening formed by a perimeter of the surrounding surface away from the floor surface, where the bottom surface is operatively connected with an opening element to open a hole in the bottom surface, where the bottom surface bottom presents the hole, where the hole is closed with the opening element that can be removed. This is also achieved through a procedure for filling a container with a food for pepper. It has a bottom surface and a casing surface projecting from a perimeter of the bottom surface, so that the animal feed can be received in the receiving space formed by the bottom surface and the casing surface and can be emptied at through an opening formed by a perimeter of the surrounding surface remote from the floor surface, where the bottom surface is operatively connected with an opening element to open a hole in the bottom surface, where the bottom surface has the hole , where the opening is closed with the removable opening element, ° - a release agent is sprayed on the side of the surrounding surface and the bottom surface directed towards the receiving space, where the release agent presents preferably a mixture of between 0.1% by mass and 10% by mass of xanthan and between 90% by mass and 99.9% by mass of oil, especially preferably between 0.5% by mass and 3% by mass of xanthan and between 97% by mass and 99.5% by mass of oil, even more preferably essentially 1% by mass of xanthan and 99% by mass of oil, and

° Next, a first component of the animal feed and then a second component of the animal feed are filled into the receiving space. By mass percentage we mean the mass percentage in the dry mass, that is, once the water content has been extracted.

• where a release agent is applied as an aerosol on the side of the surrounding surface and the bottom surface directed towards the receiving space, where the release agent preferably has a mixture of between 0.1% by mass and 10% by mass of xanthan and between 90% by mass and 99.9% by mass of oil, especially preferably between 0.5% by mass and 3% by mass of xanthan and between 97% by mass and 99.5% by mass of oil, even more preferably essentially 1 mass% xanthan and 99 mass% oil, and then a first feed component and then a second feed component are filled into the receiving space. By mass percentage we mean the mass percentage in the dry mass, that is, once the water content has been extracted.

By providing an opening element, which is operatively connected to the bottom surface to open a hole in the bottom surface, or by a method for manufacturing a corresponding container, it is possible to place the container or the canned food with the bottom surface upwards on a surface. A hole can then be opened in the bottom surface with the opening element. It is therefore possible that an animal feed can slide out of the container (almost) entirely and without any essential shape change on the surface, since air can flow through the hole into the receiving space by on top of animal feed. Furthermore, even if the emptying opening faces downwards, the animal feed can be kept in the receiving space until the opening is opened. The preferably provided application of an inner coating on the side of the surrounding surface and the bottom surface facing the receiving space can positively influence the adhesion of the animal feed to the respective surfaces and be adjusted in such a way that the feed for animals to easily slide out. The interior coating is advantageously applied in two steps: first the primer is applied and then a non-stick coating. Likewise, the release agent, which is preferably edible (for the respective animal), can serve to positively influence adhesion.

In a preferred embodiment of the container, the bottom surface has an opening, which is closed with the removable opening element. Therefore, the opening element represents in particular a seal removable from the orifice.

The opening element, in particular if it serves to close the hole in the bottom surface like a seal, must withstand the high sterilization temperatures to which such a container is also usually subjected after filling (and eventually closing) and, In addition, it must remain watertight during the storage period. Therefore, elastic or viscoelastic materials are particularly suitable as materials for the opening element. In particular, the opening element is preferably made of a polymer or a plastisol, for example, PVC-containing materials or plastisols or silicone-containing materials, or combinations thereof. It is also conceivable that the opening element is made of a different material (e.g. aluminum, plastic and/or plastic composite, etc.).

Furthermore, the hole to be opened and/or already present in the bottom surface must be as large as possible, on the one hand, so that the air flow is as large as possible and, on the other hand, it must be as small as possible. so as not to reduce the closing security and stability of the container. Additionally, it must be able to withstand the pressure fluctuations that occur during the autoclave process. Preferably, the hole is essentially circular. It turns out to be advantageous to have a hole diameter or an average extension of the hole parallel to the surface in the standing position of the container of between 0.5 mm and 10 mm, preferably between 1.5 mm and 4 mm, more preferably 2 mm to 3 mm, particularly preferably essentially 2.5 mm. With respect to a surface in the upright position of the container, it is advantageous if the diameter of the hole or an average extension of the hole parallel to the surface in the upright position of the container corresponds to between 1 and 10 percent, of especially preferred form between 3 and 6 percent, of the average extension of the bottom surface parallel to the surface.

In the standing position, the container is on the bottom surface; the surrounding surface points essentially upwards. The container is usually filled in e do, the bottom surface usually points upward; That is, it is on the perimeter that defines the emptying opening, for example.

Alternatively, for example, a partial pre-stamping or perforation may also be provided on the bottom surface, where the opening element serves to remove a correspondingly delimited part of the bottom surface from the bottom surface to form the hole. In this regard, the opening element may in particular be a lug or a lifting lug or a lifting protrusion through which the delimited/pre-stamped part can be removed or pressed from the bottom surface. Furthermore, a flap is conceivable as an opening element through which the delimited/pre-embossed part of the background surface can be pulled or torn off.

It is preferable that the surrounding surface has a cross section that increases in the emptying direction of the container. Therefore, when food falls, it immediately detaches from the wall and can better retain its shape as a whole.

The pouring direction is the direction normal to the bottom surface (or, if the bottom surface is not essentially flat, normal to the surface in the standing position of the container) and pointing from the bottom surface to the opening formed by a perimeter of the surrounding surface away from the bottom surface, through which animal feed can be emptied.

In a preferred embodiment, the surrounding surface and the bottom surface essentially have the shape of the surrounding surface and the covering surface of a truncated cone. Preferably, it is a right truncated cone whose covering surface and base surface are parallel and whose height is normal to the covering surface. Preferably, the container is in the shape of an ordinary can of wet cat food.

So that an animal feed can be removed from the container as easily as possible, without leaving residue and essentially completely, it is advantageous if the bottom surface and/or the surrounding surface have a coating on the side facing the receiving space. interior, preferably having a primer and/or a non-stick coating, where preferably the primer has a polyester resin, in particular modified and/or pigmented with aluminum, and/or has a density per unit area of between 9 g/m2 and 10 g/m2 and preferably the non-stick coating has a polyester, a phenolic resin and/or a polyester phenolic resin and/or has a density per unit area of between 7 g/m2 and 9 g/m2. In particular, it is advantageous if the inner surface of the container is as smooth as possible, for example microscopically smooth. Preferably, the inner coating serves to prevent the animal feed from adhering to the container even at sterilization temperatures of more than 110 °C. Furthermore, it is advantageous if the container is sprinkled with various oils and separating agents, for example oil and xanthan, before filling, in order to essentially increase a possible effect of the inner coating.

Preferably, a protective and/or adhesive coating is applied to the bottom surface in the receiving space over the hole closed by the opening element. The protective and/or adhesive coating must prevent corrosion in the orifice area in the case of corrosive can materials. Furthermore, the protective and/or adhesive coating may serve to improve an adhesion of the opening means to the bottom surface, so that it cannot be transferred into or onto the animal feed, for example by falling.

In a preferred embodiment, a partial surface of the bottom surface has a recess in the direction of the receiving space, where the recess has the opening to be opened and where preferably the opening element is located within the recess and/or has a smaller extension in the direction opposite to the direction of emptying than a front point in the direction opposite to the direction of emptying or the front perimeter of the surrounding surface. Therefore, wear of the opening element can be avoided, for example on conveyor belts.

The opening element may be, for example, operatively connected to the bottom surface, such that a user only has to run a finger or nail along the bottom surface to move or lift the opening element. so that the hole opens. It may also be provided that the opening element has a flap, where the flap is preferably located in the recess in the bottom surface. Therefore, a user can pull the flap to open a hole in the bottom surface with the opening member operatively connected to the bottom surface. For example, the opening element may also be in the form of a flap.

It is advantageous if the opening element has an elastic or viscoelastic material, preferably a polyvinyl chloride and/or silicone plastisol. This is particularly advantageous if the bottom surface has the hole closed with the opening element, which is closed by the opening element like a seal. Therefore, in particular, the manufacturing is particularly simple, the opening element is applied on the drilled hole, for example, preferably both from the side away from the receiving space and from the side facing towards the receiving space.

In an advantageous embodiment, the element of a

• on a side of the bottom surface facing away from the receiving space or on an outer covering on the side of the bottom surface facing away from the receiving space and

• on one side of the bottom surface facing the receiving space or an inner coating on the side of the bottom surface facing the receiving space or a protective and/or adhesive coating applied in a vicinity of the hole to be opened in the side of the bottom surface directed towards the reception space, possibly on the inner coating, where the protective and/or adhesive coating preferably has an epoxy resin pigmented with aluminum and/or a density per unit area of between 7 g/m2 and 9 g/m2.

Therefore, the tightness of the opening element closing the hole can be improved.

It is advantageous if a cover is provided to close the opening formed by a perimeter of the surrounding surface remote from the bottom surface. In this regard, the lid preferably has an edge section (for example, a lid ring), which is firmly connected to the surrounding surface, and a removable peel-off section, which is releasably connected to the edge section and which preferably it has aluminum and/or tinplate and/or a plastic and/or a plastic compound. The edge section is permanently connected to the surrounding surface, for example by folding or flanging. The removable peel section may, for example, be glued or sealed to or be an integral part of the edge section, thereby providing a partially perforated predetermined tear point. When feeding, the lid is first removed and the can is placed with the bottom surface facing up, so that the animal feed comes out of the container essentially in one piece by gravity.

The resulting opening after removing the peel-off section must be flush with the rest of the surrounding surface so that no obstacles get in the way of the animal feed during emptying. Therefore, it is preferable that the edge section on the side facing the opening is aligned with the surrounding surface in the pouring direction. This means that the inner wall of the casing surface, that is, the wall of the casing surface that comes into contact with the animal feed in the filled state of the container, is aligned with the edge section. That is, the edge section does not protrude into the area of the opening formed by the perimeter of the surrounding surface, when viewed in the emptying direction, and does not get in the way of a portion of the animal feed during emptying. . Therefore, the animal feed can fall out of the container essentially whole and without changing shape. For example, if the peel-off section is adhesively connected or sealed to the edge section, a corresponding bearing surface of the edge section to which the peel-off section is glued/sealed must face away from the opening. Provided that the peelable section can be removed by partial punching, the partial punching must follow and/or be located essentially outside the perimeter of the surrounding surface that forms the opening, but not within the perimeter; in each case, seen in the direction of emptying.

It is common for the perimeter of the surrounding surface of food containers, in particular food cans, that form the opening to have a section of edge, flanges, lips or folds, for example, to increase stability or allow a connection with a lid. Accordingly, in the present invention it is advantageous that such devices are not located in the direction of the receiving space, as is usual in ordinary cans. Therefore, in an advantageous embodiment, the surrounding surface has a surface projecting beyond its perimeter away from the bottom surface facing away from the opening. This surface can serve, among other things, to give stability to the surrounding surface and the container as a whole and, on the other hand, it can serve to close the container with a lid.

In a preferred embodiment, the bottom surface and/or the surrounding surface comprises a metal, for example, aluminum, iron, steel or mixtures thereof, in particular a sheet, for example, of the mentioned base materials, and/ or a plastic and/or a plastic compound.

With reference to the canned food according to the invention, due to the reception of the animal food in the receiving space of a container, as described herein, it can be achieved that the animal food can be emptied/dumped from the container almost without leaving residue, in its entirety and/or without using any auxiliary means or without getting your fingers dirty.

It is advantageous if a release agent applied as an aerosol on the side of the surrounding surface and the bottom surface directed towards the receiving space, preferably a mixture of between 0.1 and 10% by mass of xanthan and between 90 and 99, 9% by mass of oil, especially preferably between 0.5 and 3% by mass of xanthan and between 97 and 99.5% by mass of oil, even more preferably essentially 1% by mass of xanthan and 99% by mass of oil oil mass, separates the animal feed essentially from the surrounding surface and the bottom surface. In particular, the adhesion of the pet food to the container is reduced by the release agent, so that it is more easily detached from the container. In particular, the effect of an inner coating of the container can also be improved. The separating agent is preferably applied (before filling the container) as a finely atomized aerosol, so that it can be avoided.

It is according to the invention if the animal feed is composed of two components that are essentially spatially separated (not intermixed), where the pH of the two components preferably differs by less than 1, especially preferably by less than 0.5, and/or The salt content of the two components preferably differs by less than 5 percent, especially preferably by less than 2.5 percent, from the salt content of the components with the lowest salt content and/or the value of Water activity of the two components preferably differs by less than 0.2, especially preferably by less than 0.1. The activity value in water (aW) is defined as the relationship between the partial pressure of water vapor in the food (p) and the saturation vapor pressure of pure water (p0) at a given temperature, which here is 20 °C: aW = p/p0. By using two components, where the one component is preferably arranged in such a way that it essentially covers the second component after the food has been turned out of the container, a particularly attractive food can be achieved and, for example, can be increased acceptance by the animal to be fed. Due to the similarities in the composition of the components, a mixing of the two components or a migration of substances between the two components can be prevented, particularly during long-term storage. Furthermore, the consistency of the two components must advantageously be similar so that an animal that is to be fed with the animal food does not become irritated.

The two components are preferably a pasta and a sauce. The two components are provided in particular in areas oriented parallel to the bottom surface/surround surface in the receiving space. Preferably, the pasta is provided in an area closer to the top and the sauce in an area closer to the bottom. Then, when pouring, the pasta comes out first, which is immediately drizzled by the sauce that flows later. In relation to the total volume of the animal feed, that is, the total volume of the two components, it is preferred that the one component, in particular the pasta, represents at least 20% by volume and/or that the other component, in particular the sauce, represents at least 20% by volume.

With reference to the method according to the invention for manufacturing a container, the surrounding surface and the bottom surface can be manufactured, for example, with conventional methods, where an inner coating is then preferably applied on the side of the surrounding surface and the bottom surface directed to the receiving space, and then the bottom surface is operatively connected with the opening element to open a hole in the bottom surface.

In an advantageous embodiment of the method, the operative connection of the bottom surface with the opening element to open a hole in the bottom surface has the following steps:

• preferably application of a protective and/or adhesive coating on the side of the bottom surface facing the receiving space in the vicinity of the hole,

• hole punching on the bottom surface

• application of the material composition of the opening element from the side of the bottom surface away from the receiving space, and

• application of the material composition of the opening element from the side of the bottom surface directed to the receiving space.

The particular order of the two last-mentioned steps can also be permuted. This variant of the method represents a particularly simple possibility of manufacturing an opening element operatively connected to the bottom surface for opening a hole in the bottom surface. Furthermore, the application of the material composition of the opening element on both sides leads to improved tightness.

With reference to the method of filling a container as described herein with an animal feed, by providing a separating agent a particularly good separation of the animal feed or both components of the animal feed can be achieved from the bowl.

The container 1 has a bottom surface 3 and a surrounding surface 4 protruding from a perimeter of the bottom surface 3. The bottom surface 3 and the surrounding surface 4 form a receiving space 5 in which the animal feed can be received to form a canned food. Furthermore, a perimeter of the surrounding surface 4 remote from the bottom surface 3 forms an opening 6 through which the animal feed can be emptied from the container 1. In this embodiment, the opening 6 is closed by a lid 7. The lid 7 has an edge section 12 and a peel-off section 14. The bottom surface 3 and the surrounding surface 4 of the container 1 essentially form the covering surface and the surrounding surface of a truncated cone, where the lid 7 essentially corresponds to the base surface of the truncated cone. The bottom surface 3 has, in the recess 8 in the direction of the receiving space 5, an opening 10 closed by the removable opening element 9 with which the bottom surface 3 is operatively connected. In this regard, the bottom surface 3 The opening 9 adheres both to the side of the bottom surface 3 facing the receiving space 5 and also to the side facing away from the receiving space 5. By removing the opening element 9, the opening 10 can be opened so that air can pass through the opening 10 into the interior of the container 1, in particular between the bottom surface 3 and the animal feed with which the container 1 can be filled.

The emptying direction 11 is drawn with a broken arrow. The surrounding surface 4 has a cross section that increases in the emptying direction.

An opening element 9 is operatively connected to the bottom surface 3. to open a hole 10 in the bottom surface 3. In this embodiment, the container 1 consists of two parts, where the first part is formed by the bottom surface 3 and the surrounding surface 4. The second part essentially has the shape of the perimeter of the surrounding surface 4 away from the bottom surface 3. As long as the surrounding surface 4 essentially has the shape of the surrounding surface of a truncated cone, the second part essentially has the shape of a ring with essentially the same diameter than the perimeter of the surrounding surface 4 away from the bottom surface 3. In this regard, the second part is connected to the first, for example, by flanging, folding, gluing or welding. The second part may have a projecting edge serving as a support surface 12 of a removable cover 7. Alternatively, the second part may also be configured as a continuous surface, where a perimeter of the surface essentially corresponds to the perimeter of the perimeter of the surface. casing 4 away from the bottom surface 3. In this regard, the surface of the second part can have a partial milled groove along a loop, where the partial surface within the milled groove can be torn away, for example, with a sealing ring; therefore, the partial surface forms the peelable lid 7 in this embodiment.
