Trash bag for wet trash

Abstract

A trash bag for containing wet trash has an outer ply of fluid imperious material defining an outer front wall and an outer rear wall of the bag, and an inner ply of fluid pervious material defining an inner front wall and an inner rear wall of the bag. The inner and outer plies form a compartment between them which contains a highly fluid absorbent material. The material is capable of capturing any fluids that enter the compartment from the interior of the bag thereby minimizing fluid leakage from the bag in the event that the outer ply of the bag is breeched. The material in the compartment may be combined with or include any of a variety of additional substances designed to act on, react to or counter the effects of fluids absorbed by the material. A low-cost, consumer version of the trash bag eliminates the inner ply, and simply comprises an outer ply of fluid impervious material with an inner liner of fluid absorbent material such as cellulose fluff pulp in sheet form.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is a continuation-in-part of commonly assigned copending U.S. patent application Ser. No. 11 / 205,492, which was filed on Aug. 16, 2005, entitled TRASH BAG FOR WET TRASH, which is a continuation-in-part of commonly assigned copending U.S. patent application Ser. No. 11 / 107,514, which was filed on Apr. 15, 2005, also entitled TRASH BAG FOR WET TRASH, both of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to a plastic trash bag. It relates especially to a trash bag for handling trash with a high moisture content and commonly referred to as wet trash. [0004] 2. Background Information [0005] Most commercial and residential trash receptacles are provided with a liner consisting of a plastic trash bag. Often, trash with a significant fluid content, i.e., wet trash, is thrown into these receptacles. This is particularly so in the case ...

AI Technical Summary

Benefits of technology

[0009] Another object of the invention is to provide a trash bag which suffers minimum leakage even when punctured by an external object.

[0010] A further object of the invention is to provide a trash bag for containing wet trash which does not tend to leak even if a bag seam should be compromised to some extent.

[0013] Briefly, a bag embodied in accordance with the invention may comprise an outer layer or ply of fluid impervious sheet material and an inner ply or layer of fluid pervious sheet material. The inner ply or layer occupies at least a portion of the bottom of the bag and is seamed to the outer layer to form a compartment between the two plies or layers which contains a layer of highly absorbent material. In some low cost applications, the inner ply or layer may be omitted and the absorbent layer comprises a sheet of absorbent material that forms a liner that covers all or part of the inside surface of the outer ply or layer. When wet trash is placed in the bag, the fluid content of that trash will be absorbed by the absorbent layer. Therefore, even if the outer wall of the bag should be breached, since the fluids have been bound to the absorbent layer or liner, there should be no leakage from the bag. The same is true if a bag seam is compromised due to the weight of fluids collected at the bottom of the bag. If desired, other substances such as a deodorizing agent, a neutralizing agent or the like may be included in the compartment to complement the fluid absorbing capacity of the bag.

[0014] Since it does not tend to leak, the present bag is especially suitable as a liner for receptacles in kitchens, HAZMAT facilities, hospitals, restaurants, airports, schools, and other locations where wet trash is discarded on a regular basis.

Problems solved by technology

Often, the welded seams of these bags are not able to withstand the weight of the contained fluids and consequently the fluids frequently leak out of the bags.

In some cases, the action of dragging the bags can puncture the bag allowing the bag contents to leak out creating a public health hazard as the exposed fluids and the punctured bag reposing at curbside can attract rodents, flies and other pests.

While such bags are better able to withstand frictional forces due to dragging of the bag, they still leak when punctured by a sharp object.

Also the weight of fluids in the bags can still cause leakage at the bag seams.
