Abstract

A reusable wrap for wrapping a load, such as a palletized load, includes a rectangular section of material having two opposed parallel edges, and fasteners for securing the opposed edges to each other. The rectangular section of material is resilient and tear resistant, and includes at least one band of elastic material oriented parallel to the opposed edges. The fasteners preferably include hook and loop fasteners. The reusable wrap may be wrapped tightly around a load, stretching the band of the elastic material, and secured by attaching the opposed edges together with the hook and loop fasteners. The opposed edges may be separated from each other, and the wrap reused as required.

Description

LOAD RETAINING WRAP
Field of invention The present invention relates to a product for securing loads, such as a stack of boxes on a pallet.
Background of the invention In the storage and distribution of items of products and materials, via warehousing and/or transport trucks, it is important to have a way of securing loads, such as a stack of boxes on a pallet, in order to secure and maintain these items of materials and products. Certain load retaining materials have been used in order to aid and secure these products and materials for transportation. In recent years, such load retaining products as shrink wrap have been used in order to maintain and handle the everyday usage of products and materials either in storage or in distribution. In order to maintain the security and balance of these products and materials for storage, it is necessary to use such load retaining products as disposable shrink wrap in order to make storage and distribution effective and safe.
With greater environmental concerns in recent years however, it has become necessary to reduce disposal of such materials as plastic shrink wrap both to reduce the negative impact on the environment and also to reduce expense to corporations who deal in and handle such load retaining products as plastic wrap everyday.
With governments taking greater action on reducing waste, thus disposable plastic shrink wrap has become more of a liability than an asset. This goes along with other disposable load retaining products such as wire or metal mesh along with plastic or synthetic materials. Products or supplies to be distributed or transported, are contained with these disposable items such as plastic shrink wrap. To be distributed or transported, such products or supplies are usually palletized, and in turn enclosed with a load retaining product such as plastic shrink wrap or a wire mesh.
Plastic shrink wrap along with such items as wire mesh are removed and retain no further use once the product has been distributed or transported. Only removed, the used plastic shrink wrap is disposed of, making it bound for a landfill site.
Reusable storage and transport wraps have been proposed including in US patent 4,868,955 to Magnant et al which provides a flexible reusable wrap removably attachable to a cluster of articles. The wrap of Magnant includes a releasable fastener, such as a hook and loop fastener at the ends of the wrap to secure the wrap about the cluster of articles. Tension control of the wrap of Magnant about the cluster of articles is limited. Where the wrap is constructed from a flexible material only, the wrap simply encloses the articles to be wrapped. Where the wrap is constructed from an extensible material, the extensible material is used to enclose irregular shaped items such as bags and the like. To prevent a loose wrap from falling off of the items wrapped, additional straps have been proposed, for example a top strap is shown in US patent 4,876,841 to Jensen.
Summary of the invention An object of the present invention is to provide an improved reusable wrap product to secure loads, such as a stack of boxes on a pallet.
The reusable wrap for wrapping a load, such as a palletized load, includes a rectangular section of material having two opposed parallel edges, and fasteners for securing the opposed edges to each other. The rectangular section of material is resilient and tear resistant, but includes a band of the elastic material oriented parallel to the opposed edges. The fasteners preferably include hook and loop fasteners. The reusable wrap may be wrapped tightly around a load, stretching the band of elastic material, and secured by attaching the opposed ends together with the hook and loop fasteners. The opposed edges may be separated from each other, and the wrap reused.
In accordance with invention, there is provided a reusable wrap for wrapping a load, the wrap comprising: a section of material having first and second opposed edges, and fastening means for securing the first and second ends to each other, whereby 40098939.1 the material may be wrapped around a load in the first and second ends secured to each other.
In one of its aspects, the invention provides a reusable wrap for wrapping a palletized load, the wrap comprising a rectangular section of material having first and second opposed edges, and fastening means for securing the first and second edges to each other, the section of material including a resilient tear resistant section and at least one band of elastic material oriented parallel to the first and second edges.
Other advantages, objects and features of the present invention will be readily apparent to those skilled in the art from a review of the following detailed description of preferred embodiments in conjunction with the accompanying drawing and claims.
The preferred embodiments of the invention will now be described with reference to the drawings, in which:
Brief description of the drawing Figure 1 is a perspective view of a stack on a pallet which is draped with a reusable wrap constructed in accordance with principles of the invention.
Figure 2 is a plan view of the reusable wrap of Figure 1 extended length wise.
Detailed description of the invention Figure 1 shows a stack of products 10 mounted upon a pallet 11. A wrap, generally shown by reference numeral 9, comprises a flexible portion 12, preferably constructed from a flexible tear resistant material such as nylon, is mounted to the products 10 by a length of strap 13, also preferably constructed from nylon material, which is mounted between items of the product 10. The wrap 9 material is then wrapped about the sides of the stack. When the items of product 10 have been wrapped, adjacent side edges 14 are releasably secured to each other with fasteners 14 and 15, which preferably are a hook and loop material 15 overlapping 40098939.1 one on top of the other. Tension band 16, which is attached on both sides to the nylon material of wrap 9, gives leeway.
The nylon material forming the flexible portion 12 of wrap 9, is made up of 100%
nylon which is made up of woven strands of nylon resin. Wrap 9 includes a tension band 16 which is constructed from a two-way elastic stretch material, for example a fabric woven from Lycra T"" brand elastane fibre produced by E. I. du Pont de Nemours and Company.
Use of wrap 9 in the manner aforesaid prevents the stack of boxes from falling or becoming disassembled as it is being stored or transported. The flexible portion 12 of the wrap jacket is made of 100% nylon which does not stretch and thereby allows for complete support and retention of product which is being stored and/or transported. A wrap constructed in accordance with the principles of the invention provides a wrap product that is 100% fully reusable and which can be used on a daily manner. Wrap 9 can be used over and over again which reduces the need to use disposable plastic wrap as a load retaining product. Wrap 9 is more environmentally friendly and can reduce the cost to corporations that use other load retaining products such as disposable plastic shrink wrap. Like plastic shrink wrap, this invention is used as a load reinforcement in areas of distribution and transportation. The invention acts as a load retaining device when wrapped around the products or product that is to be transported for example. Not only does the invention retain the product in transit, just like other load retaining products, such as disposable plastic shrink wrap, it is more secure with special straps which help contain the load. Also, with the invention, tension band 16, a piece of two-way stretch material, is used which provides for tension of the wrap against the wrapped items and gives elasticity in cases of cumbersome products which are being distributed.
Tension band 16 may take several forms depending on the type of load which is to be wrapped. Tension band 16 may be constructed as a relatively large piece of two 40098939.1 way elastic stretch material attached to two other flexible portion pieces 12, preferably constructed from nylon fibre material, to form wrap 9. Using a larger portion of stretch material to form tension band 16 allows for the wrap 9 of the invention to become more elastic as it is being secured to the product which is being stored and/or transported. For better control and containment of torsional forces acting on the load 10, it is preferable to construct wrap 9 by providing a relatively smaller tension band 16 portion relative to the flexible portions 12. Torsion forces created when load 10 tends to tip or sway do not deform the flexible resilient portions 12 of the wrap 9 which acts to retain the load. Tension band 16 connects 2 flexible end portions 12 to form wrap 9 to allow jacket closures 14 and 15 to be mounted on the flexible end portions 12 and not on tension band 16. For ease of construction, It is preferable to provide tension band 16 as a lateral connecting portion of wrap 9.
Such a configuration allows a simple three piece construction for wraps having only one tension band, namely two flexible end portions 12 and one tension band 16.
Before the wrap 9 of the invention is wrapped around the product which is being warehoused or transported, two restraint straps 13 act as anchors by initially securing the invention to the product. This holds the end of wrap 9 in place and allows the rest of the application of the wrap around the items to be wrapped 10.
Once the wrap 9 has been wrapped around the items to be wrapped 10, jacket closures 14 and 15, preferably three hook and loop fasteners, with the hook portion of the fastener on one end of wrap 9 overlaps with the loop portion of the fastener on the other end of wrap 9, are engaged to close wrap 9 about items 10. This in turn, allows the hook and loop fasteners forming jacket closures 14 and 15 to bond the two ends of the wrap 9 fabric together.
On the outer side of the nylon fabric, the hook and loop fasteners consist of a rough textured fabric. The wrap of the present invention is wrapped around the product 10 in only one 360 degree fashion. This invention, as stated before, reduces the need for disposable load retaining products which are not environmentally friendly, including plastic shrink wrap and/or plastic film wrap. Thus, this invention not only acts as the load retaining item, it also is reusable which plays an important role in the environment.
40098939.1 Over time, disposable load retaining products, such as plastic shrink, produce more and more waste thus becoming more and more environmentally unfriendly. Use of this invention can reduce waste such as a plastic shrink wrap along with plastic film and other disposable load retaining products such as plastic netting and metal strapping. This invention provides the benefit of an effective load wrap but is able to be used over and over again on a consistent basis. Disposable load retaining products, such as film wrap and plastic wraps, can only be used once, before being disposed of in a garbage dump and/or a landfill site. This invention is geared toward reducing waste.
Figure 2 shows a plan view of the reusable wrap of Figure 1 extended length wise.
The straps 13 are shown more clearly in Figure 2, which are used to position one end of wrap 9 to the load to allow one person to wrap the load. Once one or more of straps 13 have been attached to the load, the length of the wrap can then be wrapped about the perimeter of the load while the strap end is maintained in position by straps 13.
Numerous modifications, variations and adaptations may be made to the particular embodiments of the invention described above without departing from the scope of the invention, which is defined in the claims.
