Lockable container

The present innovation relates to a closable container made of plastic film, which consists of a There is an upper part and a lower part, which at least partially lie on top of one another with a flat edge.

Containers of this type are for example for packaging Eggs, glasses, pastries and confectionery, made famous They are designed so that the upper and lower part go along connected to a common edge and around this edge can be folded on top of each other, with one or more Moldings of the upper part together with one or more moldings of the lower part one or more packaging

create cavities »The upper and lower parts are preferred made from one piece and folded around a built-in fold.

It is known to close such containers in such a way that you put the overlapping edges together welded, glued or by clips or adhesive strips connects with each other. These known types of closure however, have the disadvantage that on the one hand they are partly difficult to open and on the other hand, once they are are open, can no longer be closed. Also requires closing the container after Filling when using the types of closure specified above an additional work step.

The present innovation is based on the task to provide a container of the aforementioned type that can be opened and closed as often as desired without the Attachment of the closure requires a special operation.

The lockable container according to the innovation consists of an upper part 1 and a lower part 2 made of plastic film, which at least partially lie on top of one another with a flat edge 3 and is characterized in that the flat edges

the 3 of the upper part 1 and the lower part 2 formations on the rear tendon 4, have 5, one of which is at the during the closing of the container '^ taking place on top of each other the surfaces as positive formations 4 fits into a corresponding negative formation 5 of the mating surface and the surfaces in the manner of a snap fastener connects.

In order to enable the positive formations 4 to be properly inserted into the negative formations 5, it is useful to execute the positive formations 4 so that their outer contour corresponds to the inner contour of the negative formation 5.

The undercut formations 4, 5 can be in the Have a round, oval or oblong rectangular shape in plan view. It is advantageous to use frustoconical formations 4, 5, the smaller one in each case The base of the truncated cone is flush with the edge surface ^, from which it was formed. The formations 4, 5 can for example, also have an elongated shape with a trapezoidal cross-section in the longitudinal direction and on both sides be limited by surfaces that correspond to the mantle of a truncated cone. It is also advantageous to use the undercut Edge surfaces of the positive formations 4 partially to be replaced by vertical boundary surfaces 6. As a result, when the container is closed, the

positive formations 4 into the negative formations 5 facilitated, since the interruption of the undercut outer boundary surface of the formation by vertical Walls 6 no longer have the entire cross section of the negative Indentations 5 is filled, creating openings, through which located in the negative formation 5 Air can escape. The conical surface 7 of the positive formation 4 can, for example, by two or three or ..; four vertical side surfaces 6 be interrupted *

An exemplary embodiment of the container according to the invention is shown in the accompanying figures. Fig. 1 shows a side view of the container according to the innovation in the open state. 2 shows a side view of the container according to the innovation in the closed state and FIG. 3 shows an enlarged illustration of the formations 5 and 4 forming the closure according to the invention, FIG. 4 shows the formations shown in FIG. 3 in a top view. 5 shows a section of the superposed flat edges of the upper and lower parts with a closure according to the invention. 6 shows a section in the direction AB through FIG. 5 and FIG. 7 shows a section in the direction CD through FIG.

can be opened and closed again as often as you like. They are especially useful for shipping and storage suitable for goods that are accommodated in several packages in one package, but removed individually one after the other will. The closure according to the innovation also works after frequent opening and closing reliable and guaranteed a relatively strong connection between Upper and lower part of the container. Another advantage the innovation according to the closure is that he can be produced simultaneously with the formation of the container and that therefore no further operation for Closing the container is required.

As plastic films for the production of the container are available especially suitable for those with high flexural rigidity. Films made from polyetate, polystyrene, polyesters, especially polyethylene terephthalate or polycarbonate, are very suitable. Films made from rigid polyvinyl chloride can be particularly advantageous use.
