Benefits of technology

"The patent describes a technique to make it easier to open flattened plastic bags by adding gripping tabs on each side of the mouth. These tabs can be joined together to form a rolled sheet for dispensing or stacked for dispensing. The technical effect of this invention is to improve the usability of flattened plastic bags."

Problems solved by technology

Common plastic bags that are rolled, pleated, folded, or stacked together are often very difficult to open.
My kinds of mass market plastic bags are manufactured and bulk packaged in such a way that they are generally flat and devoid of air within each bag, which is efficient for manufacturing and packaging, but often very inconvenient for the consumer.
Typically, the consumer can relatively easily remove the bag from the provided dispenser means, but finds it very difficult to open the flattened plastic bag.
In many cases there is at least a two fold problem.
One problem is to determine which end of the bag is the open side as they often are visibly indistinguishable, and a second problem is after determining, usually with significant effort, the proper side to open, it is typically difficult to separate the plastic sheets at the opening, as such plastic tends to strongly cling to itself (e.g., “static cling”) and there is an additional resistance to separating the plastic sheets due, at least in part, to a vacuum force within the flattened bag.
Often due to these frustrations when trying to open such flattened plastic bags, the bag is damaged or the person simply gives up.
Few attempts have been made to facilitate the convenient opening of plastic bags such as the foregoing.

Embodiment Construction

[0015] The present invention is best understood by reference to the detailed figures and description set forth herein.

[0016] Embodiments of the invention are discussed below with reference to the Figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.

[0017]FIG. 1 illustrates an exemplary tabbed plastic bag 100 comprising gripping lip tabs, in accordance with a first embodiment of the present invention. Tabbed plastic bag 100 is shown slightly opened for clarity, and is of the type that is mostly devoid of air when packed for consumer use, and is thereby prone to static cling and vacuum opening resistance between top and bottom bag sheets. As shown in the Figure, there is a gripping tab 110 at the lip of the top bag sheet and similarly a gripping tab 130 on the bottom sheet. In the preferred embodiment shown the t...

Abstract

The invention describes means for providing gripping tabs on each side of a plastic bag's mouth to facilitate the opening thereof, especially for flattened bags, which are otherwise difficult to open.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to means for conveniently opening plastic bags. More particularly, the invention relates to providing tabs on each side of the plastic bag's mouth to facilitate the opening thereof, especially for bags, which are otherwise difficult to open. BACKGROUND OF THE INVENTION [0002] Common plastic bags that are rolled, pleated, folded, or stacked together are often very difficult to open. My kinds of mass market plastic bags are manufactured and bulk packaged in such a way that they are generally flat and devoid of air within each bag, which is efficient for manufacturing and packaging, but often very inconvenient for the consumer. Typically, the consumer can relatively easily remove the bag from the provided dispenser means, but finds it very difficult to open the flattened plastic bag. [0003] In many cases there is at least a two fold problem. One problem is to determine which end of the bag is the open side as they of...
