Animal-Proof Trash Bag

Abstract

A plastic trash bag, which may be reusable or disposable, has a zipper that requires a multi-direction opening/closing motion. The opening/closing direction of the zipper is reversed along the zipper track by an obtuse angle ( 90° - 180° . Since the zipper closure has an obtuse reverse bend, the opening of the sealed bag requires a degree of dexterity beyond that of an animal attempting to tear the bag open.

1 . A plastic trash bag, comprising:
 a plastic bag with an opening;   wherein the opening is closable by a zipper;   wherein the zipper comprises a single zipper track and a slider that can be pulled along the zipper track to open or close the zipper;   wherein the zipper track consists of two segments, which are a first segment and a second segment;   wherein the first segment and the second segment form an interior acute angle;   wherein, to open the zipper, the slider must initially be pulled along the first segment of the zipper track in a first direction, and upon reaching the second segment of zipper track, the slider must be pulled along the second segment in a second direction; and   wherein the angle between the first direction and the second direction is obtuse, such that the zipper track forms an obtuse reverse bend.   
     
     
         2 . The plastic trash bag of  claim 1 , further comprising one or more handles on the top or sides of the trash bag, wherein the handles are grippable for lifting and carrying the trash bag.
