DE3023956C2 - Packing material cut from cardboard or the like for a multiple pack of containers - Google Patents

Description

The invention relates to a packaging material blank made of cardboard or the like for a multiple pack of containers, in particular for bottles, with an upper part with cutouts for edges of the Containers and / or handle openings, as well as with side parts and side parts that laterally cover the containers floor parts that can be connected to one another. In the case of the bottom parts, the upper part has over at both ends flaps connected to these edges and roof surfaces that can be bent on both sides as a transition to Side faces, the side faces being connected to bottom flaps via inclined parts.

A packaging material blank of the above type is z. B. became known through US-PS 33 39 723, in which the upper part practice at both ends? Has bending edges connected flaps and on The side surfaces have bendable roof surfaces on both sides as a transition to the side surfaces are connected to bottom flaps via inclined parts. This packaging material blank is particular disadvantageous in that the back flaps and the counter flaps are statically disadvantageous, especially in the case of the carrying pack, the unstable closure owing to the relatively high weight of the contents of the pack Wearing in the handle recesses does not withstand The risk of the handle recesses being torn out increases all the more so than the tabs on the bottom, inserted into the slot recesses for the stability of the Packaging body can contribute little.

In order to reinforce the area of the abutting crease edges when assembling a packaging material blank to form a packaging hollow body of the above type, in particular at the shock-sensitive transition between the inclined parts and the side parts, stabilizing elements which can be folded inwards are provided according to US Pat insert inwards, but otherwise cannot contribute anything to the cohesion of the packaging, since open plug-in closures, consisting of tabs or tongues and openings, which are loosely plugged into one another.

The known packaging containers are foldable material blanks made of cardboard, which for the assembly or for the cohesion a series of openings, incisions or must have openings in or on the outer surfaces that correspond to those mentioned Tongues or tabs are intended to hold the carrier together. That kind of packaging is poor and disadvantageous regardless of the material to be used, especially since it is not ensured that the mechanical locking elements that generally work in pairs, their seat or detent sometimes only have minor approaches, interlock reliably and durably. Is particularly disadvantageous with the known multiple packs that, due to an automatic or semi-automatic The packaging process does not allow the use of durable glue or staples is.

In many cases it is desirable, for example, beer bottles, to protect them as much as possible from the incidence of light protect in order to ensure the longest possible shelf life. Also exists with the known Packaging the risk that the containers during transport because of the lack of tolerance compensation collide and break, for example bottles.

Packaging that encloses containers on all sides,

could so far only be achieved by rectangular cardboard boxes, with additional measures to protect the Containers against collision, impacts or the like are required.

The invention is based on the object of a multiple pack and a packaging material blank suitable for this purpose for the joint wrapping of several containers to create a low Has material consumption, allows the compensation of tolerances of the containers, the containers surrounds on all sides, is easy to manufacture and easy to process.
