Definitions

  • Containers in particular for holding food
  • the invention relates to a container, in particular for holding food or the like, with a shell made of at least one heat-resistant plastic layer.
  • the heat-resistant plastic layer is a layer of a composite material which consists at least of a further layer of a heat-resistant material that cannot be changed by the radiation as a support or support structure for the layer of plastic.
  • This container has the essential advantage that it can be pushed together with its contents into an oven without the plastic inner coating melting or the contents being caked on the plastic inner coating.
  • the manufacture of a container from such a preparation Difficulties arise when, for example, a fibrous layer is used as the second layer.
  • a packaging container which is to be hermetically sealed, for example, cannot be produced from such a composite material in the deep-drawing process.
  • fiber layers, in particular cardboard have the considerable advantage that they consist of a material that cannot be changed by electron radiation, but on the other hand they can be printed very easily.
  • a container which consists solely of the above-mentioned thermoplastic or of such a multilayer plastic is unsuitable for its use in an oven or the like.
  • the edge collars of containers which have been sealed in connection with a device according to the German patent application P 32 43 634.3 are influenced by the heat in the oven in such a way that they curl. This not only gives the container an unattractive appearance, but in the negative case can also adversely affect the tightness between the sealing film or lid and the container.
  • the inventor has set himself the goal of developing a heat-resistant container of the type mentioned above, in which the above-mentioned disadvantages do not occur, which is in particular very stable and remains stable and tight when exposed to temperature, which on the other hand is easy to label or is to be printed and can be used in a device known from DE-OS 32 10 566 or DE-OS 32 43 634.
  • the shell is surrounded by a blank and this is at least partially connected to the shell.
  • the shell can be formed from a heat-resistant polyester or from a • thermoplastic plastic layer, for example from polyethylene, which has been exposed to high-energy, electron or electromagnetic radiation to increase its temperature resistance, which was designed in such a way that that the thermoplastic plastic layer guarantees a permanent load of over 200 ° C (oven temperature).
  • Heat-resistant polyester can withstand 200 ° C. even within certain limits, but there are considerable temperature fluctuations in an oven due to insufficient regulation
  • edge strips are in turn separated from side or end walls by fold lines, which are delimited from a base part by further fold lines.
  • This preferred embodiment enables a very simple production of the blank, on the other hand this blank can be inserted into the drawer known from DE-OS 32 10 566. Longitudinal slots in the buckling line improve handling.
  • the shell is also inserted and the sealing device is lowered onto the edge collar resting on the edge strips. If desired, sealing can be carried out with or without a sealing film or lid. It has been shown in practice that the edge strips of the blank have the effect that the edge collar does not curl. This means that the container maintains its desired original shape, but is now provided with the blank as a supporting and supporting structure. There are no leaks with a sealed film or a lid.
  • the blank consists of a Faserstoffla- ⁇ ge is with a plastic inner coating.
  • This plastic inner coating can on the one hand bond well with the thermoplastic plastic layer of the edge collar when sealing, while on the other hand the fiber layer is suitable for printing or labeling. Since the blank is only produced by folding along folding lines, there is also no warping of the fiber material layer with respect to the plastic inner coating, as was observed in a container production by deep drawing. Since the plastic coating does not come into contact with the contents, it does not matter whether it melts at the oven temperature. Therefore inexpensive unirradiated polyethylene, hotmelt or thermolack can be used.
  • the fibrous layer can preferably consist of recycled cellulose-containing material or cardboard. - V -
  • the shell itself can in turn consist entirely of a single layer of polyester or a cross-linked thermoplastic.
  • polyethylene is an option here.
  • the thermoplastic plastic should form the inner skin and the further layer the outer skin, it being possible for further layers to be arranged between the two layers.
  • An 'outer skin of Jacquesbe ⁇ possible constant polystyrene is preferred.
  • materials that cannot be changed by radiation or other thermoplastic materials can also be used as the outer skin, if desired.
  • a film or a cover made of cardboard for example, can be sealed onto the bowl.
  • the film is sealed onto the rim flange of the tray • the other hand, the edge strip of the blank.
  • the container is very stable and, in particular, dimensionally stable, very inexpensive to manufacture, since both the polyethylene used and the recycled fiber layers are cheap.
  • the blank can easily be imprinted. Even after a longer dwell time in the oven at oven temperature, the container does not change, and in particular there is no caking of the contents on the dish.
  • FIG. 1 shows a perspective view of a packaging container according to the invention
  • FIG. 2 shows a perspective view of the packaging container according to FIG. 1 in an exploded view
  • Figure 3 is a plan view of a blank of part of the packaging container
  • FIG. 4 shows a plan view of a further exemplary embodiment of a blank
  • FIG. 5 shows a cross section through the packaging container along line IV-IV in FIG. 1.
  • a sealable packaging container R consists of three parts, namely a cardboard blank 1, a shell 2 and a sealing film 3. The latter is not shown in FIG. 1.
  • the cardboard blank 1 has a base part 4 and two sides or end walls 7 and 8 separated from the base part 4 by means of folding lines 5 and 6. Edge strips 9 and 10 are separated from the side and end walls 7 and 8 by further folding lines 11 and 12, respectively. To improve the bend along the fold lines 5, 6, 11, 12, these are provided with longitudinal slots 13.
  • the shell 2 is formed in one piece from plastic and has a circumferential rim collar 14.
  • sealable plastic films One of the commercially available sealable plastic films is used as the sealing film 3, but also here. Any other sealable cover, such as a carton or a carton coated with plastic, can be used.
  • the cardboard blank 1 consists of an outwardly facing fibrous material layer 16, which is coated with a plastic inner coating 17, preferably made of polyethylene.
  • the shell 2 has an outer skin 18 made of a plastic, preferably made of polystyrene, and an inner skin 19 made of a crosslinkable plastic, preferably polyethylene.
  • the sealing film 3 does not consist of a composite material.
  • the rim collar 14 is not only connected to the sealing film 3 but also with the edge strips 9 and »10 of the cardboard blank 1.
  • the cardboard blank 1 is particularly suitable for being placed in a drawer of a sealing machine shown in DE-OS 32 10 566.5 or DE-OS 32 43 634.3. After inserting the shell 2 in the cardboard blank, the sealing film 3 is sealed.
  • the blank la shown in Figure 4 forms a container due to the wedge-shaped shape of the side or end walls 7 and 8 and an overlap area 20 of the edge strips 10a in which the corner areas are also closed.
