Abstract

A method to create a stable unit, stacked with trays of multi-package containers. The containers are multi-packaged with a plastic resource, flexible ring type. The trays are made of corrugated cardboard which have been precompressed or embossed in predetermined areas of the base of the tray so that no tendency of the tray to be compressed under pressure from the base of the containers during an application is canceled.

Description

RELEASE CHARLES FOR STORAGE OF PLATFORMS MÜLTIEMPAQUES STACKABLE BACKGROUND OF THE INVENTION The present invention refers to the improvements in the manufacture and assembly of packaging for the handling and distribution of cans which have been multi-packaged during the use of ringed conveyors. More particularly, for improvements in folding and corrugated trays that help in the handling and distribution of said packaging. Generally, the distribution of the packages referred to above is created by mounting a flexible polyethylene support on the edge or edge area of the ends of the cans. Said support is normally shown in the "U.S. Patent" (United States Patents) 4,219,117. With the continuous progress and modification in the manufacture of cans, the diameter of the lid of the cans is becoming mostly small in relation to the diameter of the body. In doing so, the cans created in multipacks thus have a tendency to allow the cans to move independently along their central axis relative to the other cans in said multipack. This movement is inside and by the same is not a problem or harmful. Anyway, when these multipacks are then grouped and assembled in longer packages, for example in "six-packs" (packs of 4-6 cans) of 4-6 in a relatively low-walled corrugated tray for purposes of distribution, said corrugated trays have wall sections and panel sections that are compressible and thus are capable of changing their thickness under pressure. When containers assembled in multipacks are placed in these trays, they are then stacked for storage and final shipment. Said platform normally wraps at least 8 layers of approximately 7-8 trays and can be stacked on three platforms upwards. Certain conditions can create selective crushing or compression of selected areas of the cardboard trays. Which in the highest stacking condition and most impressive stack set can, in many situations, create an unstable platform or succession of platforms allowing or forcing a stack of packages to be supported from a vertical axis. Once the support begins, the distribution of forces creates additional force on the side or in the area of the pile that is supporting. The fact that the individual "six-packs" are constructed in such a way that the individual cans can move axially relatively to each other is better than having a unified "six-pack" that aggravates this potential problem. The present invention presents an improved method for creating said row of stable flooring packages.

SUMMARY OF THE INVENTION The present invention is a method for precompressing the corrugated trays in selected regions that can finally receive the lower parts of cans that can, through this, allow the creation of a stable and stacked unit of multi-package containers, therefore, no tendency of the corrugated trays to compress under pressure from the lower parts of cans during and after stacking is canceled.

DETAILED DESCRIPTION OF THE PREFERRED INCORPORATIONS Referring now to Figures 1 and 2 it will be shown that the corrugated cardboard 10 is normally made of a sandwich of material comprising a thin upper sheet of paper 12 and a thin lower sheet of paper 14 sandwiching a corrugated intermediate section 16. Said construction is standard and is widely used in the packaging industry. Figures 1, 2 and 3 further show how a precompression of a roll or an alternative die creates precompressed rings 18 (Figures 1 and 3) within the regions 20, 22 (Figure 2) of the corrugated board particularly at the base of the tray . These regions show a substantially reduced thickness of the board and will create, for all practical purposes, a section that will be insensitive for further compression after loading on platform and initial stacking. As shown in Figure 2, each precompressed ring has the size to accept a base 24 of a can 26 at a predetermined location whereby further compression of the corrugated material 16 is prevented and even prevents the movement of the can in the tray. Excellent results are obtained when the upper thin paper sheet 12 of the corrugated paperboard is compressed to the lower thin paper sheet 14 leaving the lower thin paper sheet substantially flat or having a negligible notch, as can be seen in Figure 2.

Compressing the upper thin paper sheet and the intermediate corrugated section 16 according to this invention, locally damages the corrugated section so that it can not stand the cans longer without pressing the area as shown in Figure 2. This configuration leaves the bottom sheet of paper substantially flat when stacked on top of the trays of the containers. Therefore wet and damp conditions, together with forces maintained on the trays from the cans and from the combined pressure of the tray cans on each successive layer, this compression designed minimizes the compression without unwanted control of the corrugated tray. The side walls are folded up and down, as well as adhesively secured to one another to form a tray with four side walls. While a tray with side walls is shown, it should be understood that the present invention can be incorporated into a sheet of corrugated cardboard without side walls. Said package shown later in Figure 4 is a normal distribution of the package 30 using the invention where four beer "six-packs" or drink baskets 32 held together by a flexible ring holder 36 are packaged inside a pre-compressed tray 34 so that a route or shipping driver can immediately move the multipacks inside the retail stores.

According to the prior handling technique, these trays are stacked not only in layers of at least seven boxes or trays, but the tray distribution packs are organized in stacked loads as shown in Figure 6 that there is usually a at least 8 layers high on each platform (12 layers shown). Each layer consists of a pre-compressed tray 40 packaged with beverage containers 42. Figure 6 shows a series of parquet loads 44 spaced closely from one another in the form of 2 rows. For example, Row A, three platform loads are stacked one on top of another. Each platform load 44 is stacked on a platform or wedge 46 so as to allow easy stacking of pallet loads with a conventional forklift. The preferred stacking arrangement is that shown in Figure 6. In any case, in certain prior art situations as shown in Figure 5 by not using the invention, stacking platforms or ordering trays 48 can create a displacement angle, this as a result of the compression of the tray 50 in combination with the free movement of cans 52. Wet, hot and humid climate contribute to the potential of this compression of the base of a tray. The modification to the embodiments described above and the methods may be obvious to those of ordinary skill in the art and may not bring the invention thus modified beyond the scope of the appended claims,
