Description

DETAILED DESCRIPTION OF THE INVENTION A strip of resilient plastic material which, when manufactured, is rolled onto a reel and shipped in that form to a brewery or cannery manufacturer and applied by high speed machinery to containers such as cans. Many different types of carrier constructions have been developed in the carrier material industry.

As the industry progresses, such support compositions
The surface area of the plastic material on each of the supports has been made smaller and smaller.

As a result of these developments, many modern supports are difficult to reel, which results in industrial losses for such supports.

Many of the thin plastic sheet support materials currently known in the art are improvements on the invention described in US Pat. No. 2,874,835 by O. J. Poupitch.

Sheet-like supports currently used in the industry are generally those described in U.S. Pat.
4 and 3,383,828.

Reference is made to these patents, which show a reel and support material removed from the reel and applied to a container.

The present invention relates to a container support material formed of thin elastic plastic sheet material and wound onto a reel in the form of a strip having multiple supports.

In accordance with the practice of the present invention, the supports of the present invention are wound onto reels during support manufacture, resulting in a surprisingly firm and well-aligned reel roll of support stock. The configuration is obtained.

A superior result obtained when winding with the support of the present invention is the addition of lumps or material within the support strip or material to the thin plastic sheet material on each side of the longitudinal centerline of the material. This is thought to be due to a certain curved tab formed in the .

These tabs on the support create a slight center hump in the periphery center portion of the support strip as the support strip is wound onto the reel, and this bump It is believed that in cooperation with the container enclosing band of the support at the stage, the support material on the reel is stiff and well aligned.

The objects and features of the present invention will be easily understood from the following description and drawings.

In a preferred embodiment of the invention shown in FIG. 1, each support within the strip of support material has six integrally interconnected container enclosing bands. , each support is applied to a container and the material is separated between the supports to form a six-pack beverage, such as the well-known beer or soft drinks.

The support of the present invention is also intended to be slit along its longitudinal centerline to form two three-packs when applied to a container.

The strip of support material generally includes at least 4000 individual supports wound on a reel and shipped in that form to a brewer or bottler as shown in the above-referenced patent. Mechanically applied by using a machine.

Generally speaking, it is a low-density polyethylene material used in the manufacture of support materials.

In the preferred embodiment, one support 10 is shown with a small edge of an adjacent support 10 in the sl-IJ tube shown at each end of the complete support 10.

In the support stock of the present invention, identical supports 10 are formed in an end-to-end repeating pattern of at least 4000 supports, and for convenient industrial quantities of support stock, FIGS. It is wound onto a reel 11 as partially shown in the figure.

Each support 10 includes six container enclosing bands 12.

The bands 12 are arranged in lateral pairs such that three adjacent pairs constitute one support 10.

The bands 12 of each pair of bands are integrally interconnected by a web 13 extending between the outer border edges of the bands 12.

Adjacent pairs of bands 12 of support 10 are integrally interconnected by webs 14 extending between the outer border edges of the adjacent pairs of bands 12.

Substantially no webbing is provided between adjacent supports within the support material.

The outer edges of adjacent supports 10 within the support material are connected to a slightly more than contacting degree along the line of interconnection 15 shown in FIG.

The inner periphery of each band 12 is defined by a continuous, uninterrupted inner border 16 having the general shape of a modified oval.

The outer border edge 17 of the band 12 is substantially parallel to the inner border edge 16.

It may be said that the extension of the outer border 17 through the webs 13 and 14 is also substantially parallel to the inner border 16 of the band 12.

The extension of the outer border edge of the band 12 between the webs 13 and 14 is provided with curved radially outwardly extending tabs 18.

From the foregoing description, it will be apparent that the tabs 18 add material over the uniform width of the band on each side of the longitudinal centerline through the support 10.

When winding the support material onto the reel, the tab 18 allows
The center of the reeled support material is shaped with a slight bump 20 as shown in FIG.

The slight bumps 20 ensure that the support is firmly and precisely aligned with the pedestal, layer upon layer around the reel as it is manufactured.

The problem and solution posed by the present invention will be further understood by considering FIGS. 2 and 3.

As the material is wound onto the reel, the diameter of the material becomes progressively larger, thereby changing the longitudinal alignment between supports of adjacent layers on the reel.

Thus, for example, as shown in FIG. 3, the cross sections taken are, for example, line 1-1 for the top layer, line 2-2 for the second layer from the top, line 3 for the third layer from the top. −
3 shows cross-sections of the support 10 at different longitudinal positions along the line 4-4 in the fourth layer from the top and along the line 5-5 in the fifth layer from the top.

In such an arrangement of relative supports on a reel, 1
Web bands 14 of one layer will often lie within the band openings of adjacent layers.

Additionally, the outer band portion of band 12 will often overlie and partially within the outer band of web band 14 of the next layer.

Due to the overlapping of the carrier layers on the reel in mutually nested layers, it occurs that the carrier material is loosely wound onto the reel.

However, in practicing the present invention, tabs 18 are believed to create sufficient additional material or mass within each layer and in conjunction with adjacent layers to create the slight bump 20 of FIG. It will be done.

As mentioned above, maintaining a slight bump 20 during winding results in a surprisingly stiff and well-aligned reel of support material 10.

It will be understood that variations may be made to the specific examples described above while remaining within the spirit and scope of the invention.
