Abstract

A bag includes a rectangular sheet having a top part with an aperture therein and a bottom part. The sheet further includes top, bottom, left and right edges. The sheet is folded lengthwise such that the bottom edge forms an opening to a pouch and the left and right edges are attached to respective left and right edges of the top part.

Description

FIELD OF THE INVENTION

The invention disclosed broadly relates to the field of disposable bags, and more particularly relates to the field of disposable waste bags.

BACKGROUND OF THE INVENTION

Disposable bags are well known. However, there is a need for a disposable bag that can be hung from a protrusion in a vehicle or other structure and easily used.

SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a sheet to be folded to create a waste bag according an embodiment of the invention.
FIG. 2 shows a waste bag according to an embodiment of the invention.
FIG. 3 shows a waste bag having a slit aperture according to another embodiment of the invention.
FIG. 4 shows a waste bag having an oval aperture according to another embodiment of the invention.
FIG. 5 shows a waste bag having a rectangular aperture according to another embodiment of the invention.
FIG. 6 shows a waste bag having a plurality of apertures according to another embodiment of the invention.

DETAILED DESCRIPTION

Referring to FIG. 1, there is shown a sheet 100 used to make a disposable waste bag according to an embodiment of the invention. The sheet 100 comprises a rectangular shape having a top part 102 with an aperture area A therein and a bottom part 104. The sheet further comprises top 108, bottom 110, left 112 and right 114 edges. The sheet is folded along a line 116 such that the bottom edge 110 forms an opening to a pouch and the left and right edges are attached to respective left and right edges of the top part. Different forms of attachment are described herein. The edge 110 is left loose (unattached) so that a pouch for receiving waste or other items is formed.
Referring to FIG. 2, there is shown a bag 200 made as discussed above. In this embodiment, the bag 200 comprises a round aperture in its top part so that the bag may be conveniently hung from a protrusion such as a door knob, stick shift lever, headrests, or other suitable items from which the bag may be hung.
According to an alternate embodiment, the bag 200 can be made with two separate sheets. A first sheet is longer than the second sheet and includes an aperture in its top part. The second sheet is attached to the first sheet by three of its edges being connected to corresponding edges of the first sheet such that a pouch is formed on the lower part of the first sheet.
FIG. 3 shows a waste bag having a slit aperture according to another embodiment of the invention.
FIG. 4 shows a waste bag having an oval aperture according to another embodiment of the invention.
FIG. 5 shows a waste bag having a rectangular aperture according to another embodiment of the invention.
FIG. 6 shows a waste bag having a plurality of apertures according to another embodiment of the invention.
The bags discussed herein can be made from any suitable material such as those that have sufficient strength to hold waste items and possibly such that wetness will not cause the pouch to collapse.
Examples of suitable materials include:
1. Acetate and by-products.
2. Cotton and by-products.
3. Synthetic rubber and by-products.
4. Rubber and by-products.
5. Celluloid and by-products.

19. Polyester and by-products.
20. Polystyrene and by-products.
21. Polytene and by-products.
22. Inorganic polymer and by-products.
23. Organic polymer and by-products.
24. Polypropylene (vinyl polymer) and by-products.
25. Non-woven Polypropylene (vinyl polymer) and by-products.
26. Woven Polypropylene (vinyl polymer) and by-products.
27. Polytetrafluoretilene (teflón) and by-products.
28. Polyurethane and by-products.
29. P.V.C. and by-products.
30. Paper and by-products.
31. Mixtures of the above materials.
These materials can be used in different weights According to different embodiments bags using the invention can be made by joining the edges as discussed above using any of the following: folding; soldering; welding; gluing; sewing; sealing; or any other method that the material will allow.
Waste bags made according to the invention can be used for a variety of purposes. For example the bag can be attached to a car, truck or other vehicle by placing its aperture over the stick shift lever or a hand brake, on the seat belt, or a headrest. At the home the aperture can be placed over a doorknob.
Therefore, while there has been described what is presently considered to be the preferred embodiment, it will be understood by those skilled in the art that other modifications can be made within the spirit of the invention.
