Container molded from plastic film

The iSrfindung relates to a molded plastic film Container, the two container parts of which cooperate in the manner of a push button and which can be pressed into one another and are shaped in edge areas Connecting parts can be connected to one another.

Such containers have long been known and have in particular as hygienic transparent packaging for Groceries - e.g. juice bags, fruit or passenger catering - have proven their worth. The proposal the two parts a container formed from plastic film over and pressed into one another, formed in the edge areas thereof To make connecting parts that work together like a push-button can be connected to one another, however, in the cases not proven, in which such trained containers your transport heavier (result - e.g. larger juice bags - should serve. In these cases it is not guaranteed that the connecting parts on both sides that you

assigned task, the two container parts firmly together to connect, perfectly meet. For this reason it has already been proposed that the two container parts additionally to be welded together

\ or to glue, which however causes the opening of the container

is made more difficult. In addition, this measure leads to the fact that the container part edge areas when opening the container tear and give rise to injuries.

The invention is based on the object of creating a container of the type mentioned at the outset, with which also heavier ones Objects can be transported without the risk that its two container parts during the transport detach from each other, but this container should be designed so that the connection of his both container parts is possible at any time without great effort and without the risk of injury.

This object is achieved according to the invention by a container of the type described at the outset, in which the nested Connecting parts in their head area by common Impressions are designed to be deformable,

and in which the internal connecting parts

are each designed to be deformable at least in the area of their insertion end in the sense of an expansion. With someone so trained It is sufficient for the container to firmly connect its two container parts, which are formed in their edge regions Connecting parts to be plugged into one another and preferably their head parts, which form the "bottom" of the cup-like connecting parts form to press more or less flat.

In a preferred embodiment of the invention The container has its inner connecting parts for their deformability in the area of their insertion end expansion deformations on, the preferably inwardly directed, parallel to the surface line of the inner connecting part Beads are.

The mutually associated walls of the inner and outer connecting parts of the container according to the invention are preferably designed to be rotationally symmetrical. These walls are preferably from the edge of the container part starting out initially cylindrical and then arched, conical or frustoconical, whereby not only their deformation, which takes place in the sense of an expansion, but also their production is facilitated.

The deformation of the inner connecting parts, which takes place in the sense of an expansion, is facilitated by the fact that they what in a preferred embodiment of the invention Container is the case, have inwardly directed beads in their head area, which are preferably a continuation of the beads provided if necessary in their jacket area.

In a preferred embodiment of the invention The container, the two container parts of which are connected to one another in a hinge-like manner in a manner known per se and have at their, their / joint-like connection opposite Edge areas known per se handle cutouts, wherein the one container part has a tab that extends into the lower Area of the handle cutout of the other part of the container protruding lobes under, creating an additional Connection of both container parts is created, which can also be maintained if the other, push-button-like cooperating connecting parts of the both container parts are not brought into operative engagement with one another. The aforementioned tab preferably runs essentially transversely to the handle cutout and thereby forms its lower limit, causing injuries the relatively sharp container edges can be avoided.

Further details of the invention can be found in FIGS Subclaims and the drawing. The drawing shows schematically:

Fig. 1 is a side view of a container according to the invention,

Fig. 2 shows the container shown in Fig. 1 from the front,

3 shows an inner and an outer connecting part assigned to it, before their connection,

Fig. 4 shows the connecting parts shown in Fig. 3 after their connection and

5 shows a detail from the upper edge of the container, which has a handle cutout.

The container 1 according to the invention consists in the illustrated embodiment of two essentially identically designed, hinge-like interconnected parts 2, 3, which in the folded state have a suitcase-like design, essentially cuboid containers result (see Figs. 1 and 2). The two were made in one piece trained container parts 2, "* 3 from a plan, thin and relatively rigid transparent plastic film in the deep-drawing process. Place the two container parts 2, 3 considered individually, each represents a bowl, the side walls of which are perpendicular to each other and to the bottom of the bowl, these side walls - not shown in the drawing - stiffening ribs or one of their stiffeners may have serving profiling. One side wall 4 of a container part 2 is articulated with a Side wall 5 of the other container part 3 connected. the

The remaining side walls of the two container parts each have edges 6-11 which are bent outwards 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 or 9>11" adjacent to the articulated connection and each have several connecting parts 12.13, four in the embodiment shown, which were formed during the manufacture of the container parts or thereafter from them in the deep-drawing process. In the embodiment shown, the walls of these connecting parts are essentially rotationally symmetrical, starting from the container part edge 7 or 10, initially cylindrical and then frustoconical The connecting parts 12 of one container part 3 are dimensioned so that they can be pressed into the connecting parts 13 of the other container part 2. In addition to the connecting parts 12, 13 mentioned above, the edges 7, 10 opposite the hinged connection of the container parts 2, 3 each have one Handle cutout 14, 15 . Lateral tabs 16, 17 protrude into the handle cutout 15 of the edge 10 and can be grasped from below by a tab protruding from below into the handle cutout 14 of the edge 7 when the two container parts 2 _; 3 are folded against each other.

The inner connecting parts 12 have (see. Fig. 3 and 4) in their frustoconical head area inwardly directed beads 18, which a port setting provided in their cylindrical jacket, also according to inwardly directed beads 19 form.

parts is filled with goods to be transported, the two container parts are to be folded against each other, whereby on it Care should be taken that the inner connecting parts 12, in the illustrated embodiment, only on one Container part are provided, but can also be provided on both container parts, on the outer connecting parts of the other container part are aligned. Then the connecting parts assigned to one another can be removed Push into one another without great effort and - by applying slight additional pressure on the one in the exemplary embodiment frustoconical head areas 21 - lock against each other / with the inner connecting parts deformed in the area of the transition between the circular cylindrical jacket and the head area in the sense of an expansion will. This expansion is facilitated by the aforementioned beads 18 and 19. The elongation deformations formed by the beads can also be designed in other ways, for example by a wave-like shape of the Shell or by creating differences in wall thickness in the shell.

The regular stump shape of the head part is also particularly advantageous 21, because, as can be seen from FIG Causes expansion in the edge area of the cylindrical part near the head. This will inter alia. achieved in that the transitions between the conical part and the upper flat part prevent the head part from snapping completely inwards. Also the continuation of the beads in the area of the head part and in particular in the area of the frustoconical part helps to achieve a widening of the "shell part, in which the upper base, close to the head part, is larger as the base surface with which the connecting part is formed on the edge.

The internal ones have proven to be particularly advantageous Connection parts 12 positive (with a punch) and the outer connection parts 13 negative (in a negative shape into). As a result, the wall thickness of the inner connecting part 12 in the lid area is stronger than in the outer connecting part 13, so that the inner connecting part 12 a particularly strong spreading force in the upper edge area results in «The thin formation of the outer The consequence of connecting parts 13 is that they can be deformed by indentations even without lateral beads.

In the connection according to the invention is mainly the Expansion of the inner connecting part 12 substantially, while the cover area of the outer connecting part 13 This is also why it must be pressed in so that the inner connecting part 12 can be pressed in at all is.
