DESCRIPTION:
BRIEF SUMMARY
TECHNICAL DOMAIN
The present invention relates to the packaging of empty or full bottles in superposed layers and more particularly to the packaging of bottles having to be stored, transported or presented at sales points in the form of palletized loads from the place of manufacture up to a marketing point, via a bottling point and/or a surface treatment point.
The method of storage and packaging bottles, in the form of palettizable loads, consists in placing on a pallet a first tray on which are placed bottles forming a stable layer covered by an intermediate tray (separator) adapted to allow the constitution of a superposed layer, and so on.
The problems to be solved for constituting a palletizable load giving complete satisfaction are of several orders.
Firstly, it is important to be able to constitute each layer of bottles so as to form a stable foundation, adapted to support the superposed layer. Each separator in question must therefore be able to perform a first function of centering the necks of the lower layer of bottles and a function of centering the bottoms of the bottles of the superposed layer.
Another function of each separator is to maintain the bottles so that they undergo little or no friction against one another, in order to eliminate the risks of scratchings, cracks or breaks during transports or handlings.
Another function of the separators is to be able to perform the two functions mentioned above despite the random shapes of the bottles which, due to their very material and process of manufacture, present admissible or tolerable deformations.
PRIOR TECHNIQUE
In an attempt to solve the overall problem set forth hereinabove, the prior art has proposed a first type of separator consisting in having the bottom of the bottles of a superposed row supported by the rings of the necks of the (underneath) row of bottles. This first type of separator is very frequently used for delivering empty glassware.
Such a separator is composed of a sheet of cardboard possibly associated with a plastic coating. Such separators present the drawback of being sensitive to humidity, which renders them tearable after a short or medium period of time.
The state of the art has also proposed, according to Patents FR 2 450 453 and FR 2 530 226, separators made of thermoformed plastics material. In practice, it appears that these separators present the drawback of retaining the condensation water formed along the heat-shrinkable cover which envelops the pallet. This results in the clean bottles being soiled.
Along the same lines, it must be ascertained that, for the different types of separators described hereinabove, the separator wears at the level of the points of friction between the upper part of the neck of a bottle and the bottom of the superposed bottle, with the result that particles detach from the separator and soil the clean bottles. Moreover, the number of layers of pallettizable bottles on the same pallet is limited to about 2 meters high. Stacking also remains limited to three superposed pallets.
Furthermore, such separators are difficult to re-use for storing the finished products, and for producing supports for sale, due to the deformations that they have undergone during the different handlings.
The state of the art knows a second type of separator generally used for transporting and storing full glassware. This second type of separator comprises a superposed layer of bottles, each placed in quincunx with respect to the lower layer of bottles, so that the necks of one layer of bottles are arranged between the bottoms of the superposed layer of bottles.
To make such a type of separator, the prior art has proposed using a sheet of cardboard provided with holes for receiving the necks of the bottles. Such a separator presents the drawback of lacking rigidity, of conserving the deformations undergone during transport and of being sensitive to humidity. This results in a deterioration of the covering and of the bottle.
The state of the art has also proposed, by publications FR 1 347 005, FR 1 443 9
