Definitions

  • the invention relates to a receptacle with a one-piece shell made of a thermoplastic material with an approximately horizontally projecting edge collar, an otherwise separate cut from end and side walls and a bottom being connected to the side edge collar of the shell only via laterally horizontally projecting edge strips and a plastic film or a cover formed from cardboard or plastic coated cardboard is sealed onto the edge collar.
  • a shell is known from European Patent 0 012 026, in which a heat-resistant plastic layer is a layer of a composite material which consists at least of a further layer of a heat-resistant material which cannot be changed by the radiation, as a support or support structure for the layer of plastic consists.
  • This container has the essential advantage that it can be pushed together with its contents into an oven without the plastic interior coating melting or the contents being caked on the plastic interior coating.
  • a packaging container for example, which is to be hermetically sealed, cannot be produced from such a composite material using the deep-drawing process.
  • fibrous layers in particular cardboard, have the considerable advantage that they consist of a material which cannot be changed by electron radiation, but on the other hand can be printed very easily.
  • a container that consists solely of the o. G. thermoplastic or from 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 so affected by the heat in the oven that they curl. This not only gives the container an unsightly appearance, but in the negative case can also adversely affect the tightness between the sealing film or lid and the container.
  • FR-A 2 051 643 shows a thermoplastic plastic shell in which the plastic shell itself has an edge collar and the side walls are covered with a reinforcing blank.
  • FR-A 2 141 254 shows a container which consists of a multi-layer material.
  • the inner surface of the container bottom and the container wall is formed by a layer of polyolefin and the outer surface of the container bottom and the container walls of a layer made of a synthetic, thermoplastic high heat resistance.
  • a layer of a chemical agent which brings these layers together is arranged between the material layers mentioned.
  • the container wall is bent outwards, so that either an outwardly pointing, horizontally running, flange-like mouth edge is created, or that a mouth roll is formed when the mouth edge is bent even further.
  • a flat cover can be sealed onto the mouth area.
  • a plastic shell according to the preamble of claim 1 is shown in GB-A 1 246 811.
  • this does not offer higher heat resistance and therefore cannot be exposed to an oven temperature.
  • the shell is surrounded by a blank and the edge collar is partially underlaid by the blank.
  • the inventor has set itself the goal of providing a heat-resistant container of the abovementioned.
  • the edge strips of two opposite walls are provided on both sides with extensions that connect to the non-extended edge strips of the other two sides to form a gapless corner area, and that the plastic layer for the shell to increase the temperature resistance of an energy-rich, electrons - Or has been exposed to electromagnetic radiation, which is designed so that the thermoplastic layer tolerates a permanent load of over 200 ° C (oven temperature).
  • the shell can be formed from a heat-resistant polyester or from a thermoplastic layer, for example from polyethylene, which has been exposed to high-energy, electron or electromagnetic radiation to increase its temperature resistance, which was designed so that the thermoplastic layer guarantees a permanent Endures a load of over 200 ° C (oven temperature).
  • Heat-resistant polyester can withstand 200 ° C within certain limits, but there are considerable temperature fluctuations in an oven due to insufficient control.
  • this blank can be inserted into the drawer known from DE-OS 32 10 566. After inserting the blank into the drawer, the shell is also inserted and the sealing device is lowered onto the edge collar resting on the edge strips. If desired, this can be used to seal 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 cut to size as a supporting and supporting structure. There are no leaks with a sealed film or a lid.
  • the blank preferably consists of a layer of fibrous material 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 fibrous layer with respect to the plastic inner coating, as was observed in deep-drawn container production. Since the plastic inner coating does not come into contact with the contents, it does not matter whether it melts at the oven temperature. Therefore inexpensive non-irradiated polyethylene, hot melt or thermo lacquer can be used.
  • the fibrous layer may preferably consist of recycled cellulose-containing material or cardboard.
  • 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 material 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 made of heat-resistant polystyrene is preferred. As mentioned above, however, materials that cannot be changed by radiation or other thermoplastic materials can also be used as outer skin, if desired.
  • a film or a cover made of cardboard for example, can be sealed onto the bowl. If the above-mentioned sealing machines are used, the film is sealed onto the edge collar of the shell, on the other hand, the edge strip of the blank.
  • the container is very stable and in particular also 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 period of time in the oven at the oven temperature, the container does not change, and in particular there is no caking of the contents on the dish.
  • a sealable packaging container R consists of three parts, namely a cardboard blank 1, a shell 2 and a sealing film 3.
  • 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 fold lines 5 and 6. From the sides or End walls 7 and 8 are edge strips 9 and 10 separated 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 blank Due to the wedge-shaped shape of the side or end walls 7 and 8 and an overlap area 20 of the edge strips 10, the blank forms a container in the position of use in which the corner areas are also closed.
  • the shell 2 is made in one piece from plastic shaped and has a circumferential edge collar 14 which is completely undercut by the edge strips 9 and 10 and the overlap region 20 in the position of use.
  • sealing film 3 One of the commercially available sealable plastic films is used as the sealing film 3, but any other sealable cover, such as a cardboard box or a cardboard box coated with plastic, can also be used here.
  • the cardboard blank 1 consists of an outwardly facing fibrous 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.
  • edge collar 14 is not only connected to the sealing foil 3, but also to 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 or DE-OS 32 43 634.3. After inserting the shell 2 in the cardboard blank, the sealing film 3 is sealed.
