Definitions

  • the invention relates to a container formed from plastic film, the two container parts of which can be connected to one another via connecting parts formed in edge regions, which can be pressed into one another and interact with each other like a push button.
  • Such containers have been known for a long time and have proven themselves in particular as hygienic transparent packaging for foodstuffs, for example juice bag containers, fruit or passenger catering.
  • the proposal to make the two parts of a container formed from plastic film connectable to one another via connecting parts formed in their edge regions, which can be pressed into one another and interacts with push buttons has not proven successful in cases in which containers designed in this way transport heavier objects - for example larger juice packs - should serve.
  • this measure leads to the fact that the edge of the container part can tear when the container is opened and can give rise to injuries.
  • the invention has for its object to provide a container of the type mentioned, with which even heavier objects can be transported without the risk that its two container parts will come apart during transport, but this container should be such that the connection of its two container parts is possible at any time without great effort and without risk of injury.
  • a container of the type described in the introduction in which the interconnected connecting parts are designed to be deformable in their head region by being pressed in together, and in which the inner connecting parts are each designed to be deformable in the sense of an expansion at least in the region of their insertion end.
  • its inner connecting parts have, for their deformability in the region of their insertion end, expansion deformations which are preferably inwardly directed beads which run parallel to the surface line of the inner connecting part.
  • the mutually associated walls of the inner and outer connecting parts of the container according to the invention are preferably rotationally symmetrical. These walls are preferably initially cylindrical starting from the edge of the container part and then curved, conical or frustoconical, which not only facilitates their deformation in the sense of widening, but also their manufacture.
  • the deformation of the inner connecting parts which takes place in the sense of widening, is facilitated by the fact that, as is the case in a preferred embodiment of the container according to the invention, they have inwardly directed beads in their head region, which preferably continue the beads which may be provided in their jacket region form.
  • the container 1 consists of two essentially identical parts 2, 3 which are connected to one another in an articulated manner and which, when folded, result in a box-like, essentially cuboid-shaped container (see FIGS. 1 and 2).
  • Kig-shaped container parts 2, 3 made of a flat, thin and relatively rigid plastic transparent film in the deep-drawing process.
  • the two container parts 2, 3 each represent a shell per se, the side walls of which run perpendicular to one another and to the base of the shell, these side walls — not shown in the drawing — can have stiffening ribs or a profiling serving to stiffen them.
  • One side wall 4 of one container part 2 is articulated to a side wall 5 of the other container part 3.
  • the other side walls of the two container parts each have edges 6-11 which are bent outward at right angles and which, when the two container parts 2, 3 are folded against one another, lie flat against one another.
  • the edges 7, 10 opposite the articulated connection of the two container parts 2, 3 are each made wider than the edges 6, 8 and 9, 11 adjacent to the articulated connection and each have a plurality of connecting parts 12, 13 in the embodiment shown which were formed during the manufacture of the container parts or thereafter from them using the deep-drawing process.
  • the walls of these connecting parts are essentially rotationally symmetrical in the embodiment shown, starting from the edge of the container part 7 or 10, they are initially cylindrical and then frustoconical.
  • the connecting parts 12 of the one container part 3 are dimensioned such that they can be pressed into the connecting parts 13 of the other container part 2.
  • the edges 7, 10 opposite the articulated connection of the container parts 2, 3 each also have a handle cutout 14, 15. Lugs 16, 17 protrude into the handle cutout 15 of the edge 10, which can be gripped under by a tab 20 projecting from below into the handle cutout 14 of the edge 7 when the two container parts 2, 3 are folded against one another.
  • the inner connecting parts 12 (see FIGS. 3 and 4) have in their frustoconical head region inwardly directed beads 18, which form a continuation of the inwardly directed beads 19 provided in their cylindrical shell.
  • the two container parts are to be folded against one another, taking care that the inner connecting parts 12, which are provided in the illustrated embodiment only on one container part, but can also be provided on both container parts the outer connecting parts of the other container part are aligned.
  • the mutually associated connecting parts can then be pushed into one another without greater effort and - with slight additional pressure on the frustoconical head regions 21 in the exemplary embodiment - locked against one another, the inner connecting parts in each case being deformed in the region of the transition between the circular cylindrical jacket and the head region in the sense of widening. This expansion is facilitated by the aforementioned beads 18 and 19.
  • the elongation deformations formed by the beads can also be designed in a different way, for example by a wave-like shape of the jacket or by generating wall thickness differences in the jacket.
  • the truncated cone shape of the head part 21 is also particularly advantageous because, as can be seen from FIG. 4, an internally stable position forms when pressed in, but this causes an expansion in the edge region of the cylindrical part near the head. This will u. a. achieved in that the transitions between the tapered part and the upper flat part prevent the head part from completely snapping inside.
  • the continuation of the beads in the region of the head part and in particular in the region of the frustoconical part also contributes to an expansion of the shell part in which the upper base area close to the head part is larger than the base surface with which the connecting part is formed on the edge .
  • the inner connecting parts 12 positively (with a stamp) and the outer connecting parts 13 negatively (into a negative shape).
  • the wall thickness of the inner connecting part 12 in the cover area becomes thicker than in the outer connecting part 13, so that the inner connecting part 12 has a particularly strong spreading force in the upper edge area.
  • the thin design of the outer connecting parts 13 has the consequence that they can be deformed by pressing without lateral beads.
  • the expansion of the inner connecting part 12 is mainly essential, while the lid area of the outer connecting part 13 must therefore also be pressed in; so that the pressing of the inner connecting part 12 is possible at all.
