BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to stackable containers and particularly stackable containers for transporting, storing, and displaying cans.
With respect to transportation and storage it is a main goal in the food industry to minimize the space requirements of the packaging unit in relation to the goods. A further important condition lies in that the packaging units are stackable, easy to handle and that the removal of the goods from the packaging units is possible in a simple manner. Depending on the kind of market, it often is desirable that the goods can be positioned on shelves, while still being contained in the packaging unit, so that the customer can remove the goods from the packaging unit. The latter is particularly the case in the so-called discount shops or in supermarkets as well as other hypermarkets.
Herein, problems arise in particular with respect to transportation and storage of cans for food and feeding stuff, since these cans in most cases are comparatively heavy and upon formation of larger packaging units by a number of cans, the weight resulting therefrom requires a stable packaging which generally again increases the packaging volume.
Up to now when packing cans, for example cans with nutrition or cans with cat or dog feeding stuff, mainly common cardboard packagings were used, which, however, had to be broken open for removing the goods and thus were not suitable for being directly positioned on shelves. For this reason, as packaging for cans, people started to use a cardboard container open on top, having a container bottom and four side walls for accommodating the cans and covered entirely with a shrink foil. Upon removal of the shrink foil, the open top cardboard box could then be positioned on shelves so that the customer could take the goods out of the cardboard container without difficulty. The disadvantage of this kind of packaging is that two different materials are used, namely cardboard and plastic shrink foil, and moreover that the cardboard box looses stability when it becomes humid. A further disadvantage is that the cardboard packages as a rule cannot be reused, and like the shrink foil wastes have to be forwarded to a separate disposal. This is disadvantageous for environmental reasons.
SUMMARY OF THE PRESENT INVENTION
In accordance with the present invention, the container is no longer manufactured from cardboard but of plastic material, preferably in one piece, wherein the container essentially is formed without side walls by a container bottom and by holding tongues protruding in an upward direction from the container bottom. The holding tongues are disposed at the marginal side over the circumference of the container bottom, namely on a gap to the compartments and/or the cans to be received in the compartments, so that the holding tongues form suitable support faces for the cans received in the container. At the same time, the holding tongues in their height essentially correspond to the thickness of the container bottom or only slightly exceed the height of the container bottom, preferably formed as hollow profiles, and thereby contribute to the stability of the container. Due to their low height, the holding tongues in no way contribute to load distribution in the stack, but the cans received in the container are used for load distribution, so that in the stack the load from the container bottom of the stacked layer above is further distributed in a downward direction through the cans. For this reason, the container is effective in a load structure without having to show self-carrying functions. Thereby, it is possible to give the container such a design that a number of cans can be accommodated at the lowest possible volume of the container itself. This also is further supported by the arrangement of the holding tongues directed to the gaps between cans, as thereby the space between the holding tongues is free for the cans, so that in practice the dimensions of the packaging unit are defined by adding the diameters of the cans placed one
