DESCRIPTION:
BRIEF SUMMARY
The invention relates to a bottle crate for plastic bottles in accordance with the preamble of patent ciam 1. Such bottle crated for plastic bottles accomodate the bottles each in location parts and support them using the crate bottom. Load degradation in the stack herein is directly effected through the bottles received in the crate. The invention, in particular, is applicable to bottle crates for plastic bottles made from PET in the field of disposable goods. As non-returnable bottles of that kind in many countries just are thrown away by the customers, the bottle crate, once emptied, is to be returned to the bottling firm therein requiring as little transport space as possible. For this reason, to a great extent crates are used which are similar to low-built crates.
During load degradation in the stack through the bottles received in the tray, carrying on the closing cap often damages the text on the cap and, moveoever, often causes leakage. Carrying on the bottle shoulder and/or the bottle neck scratches the bottle surface and due to the turbidity of the bottle wall gives the impression of dirt to the consumer. This effect of being scratched has different reasons, namely somewhat more than the bottle; is very small, for which reason the bottle turns during transport because of transport vibrations;
It is object of the invention to overcome the disadvantages of the described prior art, in particular, creating a bottle crate in which damage of the bottle and/or bottle closing cap of the next lower stack layer can be avoide safely but without much expenses with respect to manufacturing technology and construction of the bottle crate.
In accordance with the present invention, said object is solved by the features contained in the characterizing clause of claim 1, advantageous further develompents of the invention being characterized by the features contained in the subclaims.
In accordance with the invention, on the side of the crate at least one annular contact member made from a material softer than that of the carrier is arranged at the crate on the contact area or the contact areas between each location or receiver part and the associated bottle of the lower stack layer. Thereby, the support of the crate of the upper stack layer with respect to the bottles of the lower stack layer is effected by insertion of contact members made from a material being softer than that of the carrier, this bringing about a series of advantages. Said contact members which in a preferred embodiment may be formed by concentrically peripheral sealing rings preferably are introduced in corresponding undercuts or recesses of the accomodation members. Herein, said contact members can be held in the recesses and/or undercuts by positive locking or vacuum tension, however, preferably an injectable material is used which is injected into the undercuts and herein slightly protrudes over the crate. Instead of annular contact areas it also is possible to use individual contact pieces which are disposed in the location member in circumferential distance peripherally around the bottle. Instead of holding the contact areas in recesses etc., these can also ber realized by coating the crate bottom. A flexible resilient plastic material is used as material for said contact areas which in a preferred embodiment are made from the plastic material ethylene vinylacetate (EVA).
The advantage of the invention in particular lies in that the material binds with the crate body and that, because it consists of a flexible resilient material, it can be burdened for longer time. Moreover, it is an advantage that the contact members out of flexible resilient material can match to the bottle body. Because of the flexible resilient material of the contact areas the bottle neck and/or the bottle shoulders and/or the bottle closing cap are no longer scratched. Furthermore, by insertion of the contact area it can be achieved also that the bottle will not turn any more during transport. This, too, substantially contributes that the bottle cannot be scratched
