Definitions

  • the present invention relates to a sealable multi-part container for packaging food, in this respect a multi-part container that can be closed with a heat-sealable sealing film.
  • the container is in particular a menu bowl.
  • Containers for packaging food that can be sealed with a heat-sealable sealing film are typically used for take-away catering or for Togo meals or suppliers of ready-made meals.
  • the sealable containers currently used are containers that are intended for single use.
  • the containers currently used are typically only used once and disposed of after use.
  • Such containers are also used, for example, to take home food that has not been fully eaten on site or to deliver ready-to-eat food to the customer or to give it to the customer for later consumption.
  • the containers are kept by the provider of the food and then, if necessary, sealed with a heat-sealable covering film, which is typically done using a heat-sealing device.
  • Such containers are used, for example, in restaurants, snack bars, canteens, but also, for example, when feeding patients in hospitals.
  • containers have already been developed for this purpose that consist of recyclable material and/or biodegradable material and/or compostable material, for example bagasse.
  • the disadvantage of such containers is that although recycling or composting is possible, raw materials and energy are required to produce the containers and these containers are only used once.
  • such containers have the disadvantage that they often do not have a particularly high level of stability, so that the containers can be damaged, especially when using a knife and/or fork, so that the contents of the container leak, which is unsatisfactory for the user and leads to rejection of such containers.
  • the container according to the invention is a multi-part container that can be closed with a heat-sealable sealing film.
  • the container is used for packaging food, in particular ready-made meals, such as a ready-made menu, which can consist, for example, of a main course and a side dish.
  • the multi-part container is in particular a multi-part menu tray.
  • multi-part is understood to mean that the container consists of at least two separate, separable components, namely a carrier shell and an inner shell.
  • the carrier shell has one or more receiving compartments that are open towards a front side of the carrier shell, each of which has a rear bottom and a circumferential side wall that extends from the rear bottom to the front and has a side edge opposite the bottom.
  • the storage compartments are accordingly limited by the side wall and the rear floor and are open to the front, so that the storage compartments are accessible from the front.
  • the container also has an inner shell, the inner shell having one or more compartments open towards the front, each of which has a rear bottom and a circumferential side wall extending from the rear bottom to the front with a bottom opposite side edge.
  • the inner shell and the carrier shell are designed in a similar way in their basic shape.
  • the side edge of the respective side wall of the inner shell is designed as a sealing edge and has a sealing surface on its front side for sealing the heat-sealable sealing film in order to close the one or more compartments by means of the heat-sealable sealing film.
  • the inner shell is arranged in the carrier shell in such a way that the one or more compartments of the inner shell are inserted into the one or more receiving compartments of the carrier shell and the sealing edge protrudes from the carrier shell on the front of the container.
  • the protrusion of the sealing edge relative to the carrier shell ensures that when the covering film is applied from the front of the container, the inner shell or the compartments of the inner shell are reliably closed with the heat-sealable sealing film.
  • the sealing film is not sealed onto the carrier shell or is sealed with the carrier shell.
  • the inner shell and the carrier shell are detachably connected to one another.
  • the particular advantage of using an inner bowl and a carrier bowl is that the inner bowl, which is used to actually hold the food and is closed with the sealing film, can be made less stable, which means that material and thus waste can be saved because the carrier bowl Due to the arrangement of the inner shell in the carrier shell, the inner shell provides the necessary mechanical stability, so that despite the use of inner shells with a low thickness, there is no risk that the inner shell will be damaged when handling the container or when eating the food directly from the container The inner bowl is damaged when using cutlery. In addition, due to its higher mechanical stability, the carrier shell ensures that even if damage to the inner shell occurs, for example when using knives and forks, the contents of the respective compartment do not escape from the container, thereby avoiding contamination due to leaking contents.
  • the carrier shell can be reused, whereas the inner shell is preferably intended for single use. Because the inner shell is or will be arranged in the carrier shell, the inner shell can be produced with a much lower cost of material than would be the case with one-piece containers. The waste generated by disposing of the inner shell is therefore much lower than with one-piece containers. After using the multi-part container, the user can detach the inner shell from the carrier shell and dispose of it, whereas it is intended that the carrier shell is reused.
  • the end customer can purchase such a carrier tray, for example from a provider of take-away food, and return this container when purchasing take-away food when visiting this provider or a provider who also offers such containers again or can be reused.
  • the retailer or provider of the food can then use this carrier tray to package the food by inserting a new inner tray into this carrier tray and then filling the food into this inner tray and sealing it with the heat-sealable sealing film.
  • an inner shell which is preferably a disposable shell, insofar as a shell that is not reused, is also to be viewed as advantageous from the following points of view:
  • the reuse of the carrier shell and the Using a new inner bowl has the advantage that it can be easily ensured that the surface that comes into contact with the food is attractive and perfect from a hygiene point of view. It is also particularly easy to ensure in this way that that the surface of the inner bowl that comes into contact with the food is clean and/or possibly even sterile.
  • the inner shell and the carrier shell are arranged in such a way that the one or more compartments of the inner shell rest against the entire surface of the carrier shell, at least in the area of the respective base.
  • An air gap or cavity can certainly be formed in the area of the side walls, since these surfaces are typically subject to less stress. This allows thermal insulation to be achieved.
  • the side wall and the bottom of the respective compartment rest against the support shell over their entire surface.
  • “fitting over the entire surface” is understood in particular to mean that there are no cavities or gaps between the components that fit over the entire surface.
  • the inner shell and the carrier shell are arranged in such a way that between the one or more compartments of the inner shell and the respective Receiving compartment of the carrier shell one or more cavities are formed.
  • the carrier shell has support structures on the inside in the area of the receiving compartments, which extend from the bottom of the receiving compartments to the bottom of the received compartment.
  • the support structures are designed in such a way that one or more cavities are formed between the bottom of the compartment and the bottom of the receiving compartment.
  • the side walls of the receiving compartments can also have support structures that extend to the side walls of the compartments.
  • the inner shell has corresponding support structures instead of or in addition to the support structures of the carrier shell.
  • compartments and the receiving compartments are conical. This makes it easier to insert the inner shell into the carrier shell, so that the inner shell is virtually self-centered in relation to the carrier shell.
  • the contours of the receiving compartments and the contours of the compartments correspond to one another in such a way that the carrier shell and the inner shell are arranged in a nested manner and/or identical carrier shells can be arranged in a nested manner and/or identical inner shells can be arranged in a nested manner.
  • Such an embodiment enables particularly space-saving storage of the inner shells and carrier shells.
  • the sealing edge has a laterally projecting, circumferential edge section, the circumferential edge section resting with its back against a circumferential support edge of the carrier shell. It is considered particularly advantageous if the sealing surface protrudes towards the front in relation to the peripheral edge section.
  • the surrounding edge section essentially forms an abutting edge, with the abutting edge causing damage to the sealing surface of the sealing edge from the side acting forces is avoided. This is particularly advantageous given the fact that the inner shell has low mechanical stability, so that even small forces, for example when transporting the inner shells, could lead to damage. However, damage in the area of the edge sections is harmless to the function of the sealing surface. In this respect, the sealing surface is protected by the edge section.
  • the inner shell and the carrier shell have adjacent, laterally protruding, preferably circumferential edge sections, the container also having an elastically deformable fastening body.
  • the edge sections can in particular be designed in the form of a fold.
  • the fastening body has a fastening section which surrounds the inner shell and the support shell for releasably fastening the fastening body to the edge sections of the inner shell and the support shell, the fastening section having a groove on the inside, the adjacent edge sections of the inner shell and the support shell being mounted together in the groove and are held.
  • the fastening body is elastically deformable, the fastening body can be pulled over the two edge sections and the two edge sections are then held in the groove in a clamping manner.
  • the elastically deformable fastening body is preferably ring-shaped and/or band-shaped, so that the fastening body is only formed in the area of the edge sections and does not enclose the carrier shell in the area of the side walls and in the area of the base.
  • the fastening body preferably consists of an elastomer, for example silicone. It is entirely conceivable that in an embodiment with a fastening body, the sealable sealing film is also sealed onto the elastically deformable fastening body.
  • the inner shells do not have the sealing edge, insofar as the side edge of the inner shell is not designed as a sealing edge, but instead Fastening body forms the sealing edge, the sealing edge has a sealing surface on its front for sealing the heat-sealable sealing film for the purpose of closing the one or more compartments by means of the heat-sealable sealing film, the section of the fastening body having the sealing surface on the front of the container opposite the carrier shell and the inner shell protrudes.
  • the explanation of the advantageous developments of a multi-part container in which the inner shell has the sealing edge applies accordingly to a multi-part container in which the fastening body has the sealing edge.
  • a fastening body also has the advantage that the inner shell and the carrier shell do not have to have any fastening structures in the form of undercuts, which makes the production of the inner shell and the carrier shell easier.
  • a thermoforming process is also made possible by the fact that the inner shell can be made correspondingly thin, in particular only having a thickness of 0.05 mm to 1 mm, preferably 0.05 mm to a maximum of 0.5 mm.
  • the inner shell and the carrier shell have fastening structures that interact with one another in a form-fitting manner in their respective edge regions and which form a snap connection.
  • the snap connection is formed in particular in that the inner shell has a holding section bent towards the back in the edge region, the bent holding section engaging behind an edge region of the carrier shell on the back.
  • a detachable connection is formed between the inner shell and the carrier shell when the sealing film is sealed. This can be done, for example, by placing the sealing edge of the inner shell on a back side opposite the sealing surface Carrier shell rests, in particular rests against the respective side edge of the carrier shell, the sealing edge on the back being at least partially provided with an adhesive layer, the adhesive layer materially connecting the sealing edge of the inner shell to the carrier shell under the influence of heat when sealing the sealing film.
  • the inner shell essentially adheres to the carrier shell and the inner shell and the carrier shell are sufficiently firmly connected to one another, with the adhesive layer being chosen such that the inner shell can be removed from the carrier shell again after using the container.
  • adhesive residue remains on the carrier shell after the inner shell has been removed, such residues do not have a negative effect on the reuse of the carrier shell since the carrier shell can be cleaned, for example in a dishwasher. Even if adhesive residues still remain on the carrier shell, these adhesive residues do not have a negative effect on the use of the carrier shell, since these adhesive residues are covered by the new inner shell when the carrier shell is used.
  • the inner shell completely covers the front of the carrier shell.
  • the inner shell has less dimensional stability than the carrier shell.
  • the dimensional stability of the container is essentially determined by the carrier shell into which the inner shell is inserted, preferably fitting over the entire surface.
  • the inner shell has a smaller material thickness than the carrier shell.
  • the carrier shell has a material thickness of 1 mm to 5 mm and/or the inner shell has a material thickness of 0.05 mm to 0.5 mm.
