Definitions

  • the invention relates to a sterilizable combination packaging as a preserve for food and other filling goods and a method for their production.
  • One-piece containers, trays or multi-compartment trays made of steel, aluminum, plastics or laminates made of metal and plastic are used for the packaging of ready meals, in particular heat-sterilized ready meals in canned form.
  • the associated lids of these containers or trays are each made from the same material as the lower part or from one of the aforementioned materials, the connection of the lid and container, tray or lower part being effected by mechanical flanging via a seal by welding or heat sealing.
  • containers or trays made of plastic have the disadvantage of a very complex multilayer wall consisting of barrier plastics, such as e.g., because of the problem of the gas permeability of plastics at elevated temperatures, here at temperatures of heat sterilization.
  • barrier plastics such as e.g., because of the problem of the gas permeability of plastics at elevated temperatures, here at temperatures of heat sterilization.
  • EVAL Ethylene vinyl alcohol
  • PVDC polyvinylidene chloride
  • polyacrylates nitrile plastics or special crystalline polyamides between polypropylene or polyesters.
  • Such 0.5 mm - 4 mm thick multi-layer plastic structures have the disadvantage of complex, costly manufacture, in particular shaping. They also have the disadvantage that it is practically impossible to recycle the production waste from the flat webs and the shaped containers and trays.
  • Flexible laminates made of plastic-aluminum-plastic, e.g. Laminated or coated in the thickness of 10-100 ⁇ m polyester with 10-100 ⁇ m aluminum and 10-100 ⁇ m polyolefin (polypropylene or polyethylene) are formed into shells or hollows by stretching. These troughs are filled with the food and sealed using a lid tape, which is constructed in the same way as the laminate of the bowl, using a vacuum or an inert gas flush. After sterilization, these packs can be stored as canned goods without cooling for up to 2 years.
  • plastic-aluminum-plastic e.g. Laminated or coated in the thickness of 10-100 ⁇ m polyester with 10-100 ⁇ m aluminum and 10-100 ⁇ m polyolefin (polypropylene or polyethylene) are formed into shells or hollows by stretching. These troughs are filled with the food and sealed using a lid tape, which is constructed in the same way as the laminate of the bowl, using a vacuum or an inert gas flush. After sterilization,
  • packs of flexible laminates described have the disadvantage of low dimensional stability and the tendency to form an unsightly external appearance due to the formation of folds, in particular if the filling material is viscous or has no inherent stability.
  • packs made from these flexible laminates cannot be multi-compartment trays because the inherent stability of the troughs is too low because the laminate does not allow sufficiently steep partition walls for the troughs because of the lack of formability.
  • the object of the present invention is to develop a combination packaging which does not have the aforementioned disadvantages and to specify a method for producing such a combination packaging.
  • the object is achieved by a combination packaging, which is characterized by the features of claim 1 distinguished, and solved by the method set out in claim 12. Further advantageous embodiments of the invention result from the features of claims 2 to 11 as well as 13 and 14.
  • the combination packaging according to the invention consists of: - a shell made of a single-layer plastic, - a lid made of a plastic-aluminum-plastic laminate, - A trough made of a plastic-aluminum-plastic laminate.
  • the shell from e.g. Polyethylene, polypropylene, polyester, polyamide can be designed as a simple shell or multi-compartment shell. After filling the bowl and evacuating or gassing the contents, it is sealed with the edge of the bowl and the webs between the compartments of the bowl in the case of the multi-compartment bowl by exposure to heat.
  • the plastic-aluminum-plastic laminate of the trough is stretch-formed and surrounds the plastic shell more or less tightly and is sealed with its edge to the edge of the shell from below. In a further embodiment, it can also be sealed with the cover extending beyond the edge of the shell.
  • the combination pack according to the invention is further characterized in that it contains, in the form of prepared foods, as several components of a menu for accommodating 50 to 1500 ml, normally useful for domestic use, up to quantities of up to 5000 ml suitable for catering is accommodated in the individual compartments of a multi-compartment shell, or is suitable as a one-component dish in a single shell.
  • An advantageous further property of the combination packaging is that after heat sterilization of the contents in the package it can be stored for at least 2 years without cooling and the contents are ready for consumption after rapid heating in a water bath, in a convection oven or in a microwave oven.
  • the combination pack described above is produced in several steps; advantageous in a continuous molding, filling and sealing process, for example in the following way: -
  • the plastic shell is thermoformed from a flat sheet of a thermoplastic, for example polypropylene or polyester or polyamide or other in a thickness of 0.1-3 mm.
  • the heated plastic sheet is pressed against a mold by means of compressed air or vacuum, so that after cooling, the plastic takes on the shape of the shape, be it a single shell or a multi-compartment shell, of the intended filling volume.
  • the filled package which now consists of a plastic shell and a laminate lid, is given a further packaging shell made of a flexible, plastic-aluminum-plastic laminate.
  • This additional packaging envelope is the reason for the term combination packaging or combination packaging.
  • the plastic-aluminum-plastic laminate required for the packaging envelope is formed from a roll, using compressed air or a stamp, to form a trough by stretching at room temperature.
  • the contour of this trough corresponds to that of the plastic shell without the formation of the webs and its volume is such that the plastic shell fits snugly in this trough.
  • the vertical, wall-connected walls of the multi-compartment shell are shaped in such a way that either the shapes of adjacent walls are adjacent to one another in pairs or approximately adjacent to one another, or the shapes of one wall touch or touch the adjacent wall.
  • Such a multi-compartment tray has the advantage, on the one hand, that it scarcely deforms, in particular after the filling material has been taken up, and thus facilitates the subsequent sealing processes, and, on the other hand, favors the stability of the combination packaging as a preserve or prevents it from denting, which reduces the aesthetic appearance of the combination packaging benefits.
  • a plate-shaped rigid base can also be arranged between the shell and the trough, both when using the simple shell and the multi-compartment shell with or without formations.
  • the floor which can be made of the same material as the bowl, is placed in the trough before the bowl follows. At the edges at least partially flank parts can be assigned to the floor, which rest against the walls of the trough and thereby contribute to further stability and / or positioning of the floor.
  • the floor can also e.g. by gluing either to the trough or in particular to the shell.
  • inserts can be inserted with the same advantageous effect as spacers between adjacent walls, which in particular consist of the same plastic as the shell.
  • the combination packaging according to the invention consists of a shell 2 or 20 with flanks 29, a trough 3 with flanks 39 and a lid 1, the edge 25 or 26 of the shell 2 or 20 and the lid 1 being connected to one another by a sealing seam 6 and these two in turn with a second sealing seam 7 with the edge 35 of the trough 3 and / or possibly with the cover 1 projecting beyond the edge 25 or 26 of the shell 2 or 20
  • a multi-compartment shell 20 has walls connected by webs 21, which can be provided with formations 23.
  • the formations 23 of adjacent walls 22 touch or are arranged so close to one another that they restrict or completely prevent deformation of the edge 26 of the shell 20.
  • An analogous change in the deformation in multi-compartment trays 20 can be accomplished in that the multi-compartment tray 20 has inserts 4 as spacers in the slot 24 formed by adjacent walls 22 and web 21.
  • a plate-shaped rigid base 5 is arranged between the shell 2 or 20 and the trough 3 in order to improve the stability both when using the simple shell 2 and the multi-compartment shell 20 with or without formations 23.
  • the bottom 5 can at least partially have flank parts 51 on the edges, which abut the walls of the trough 3 and / or shell 2 or 20 and thereby bring about additional stability. At the same time, the flank parts 51 serve to position the Bottom 5.
  • the bottom 5 can also be fastened to the trough 3 or to the shell 2 or in particular to the multi-compartment shell 20, with the result that when the multi-compartment shell 20 is attached, in particular the stability thereof is increased and in Attachment to the shell 2 or the trough 3, the overall stability of the combination packaging is favored, which benefits the aesthetic appearance.
