Abstract
Abstract The bags may be sculptured with a wave pattern defining a periphery of the corner regions on either side of the mouth of the bag. The bags may be secured to two tabs which are connected to the corner regions via the wave pattern, which is perforated. By attaching the tabs to a carton and pulling the bag, the bag severs cleanly from the tabs at the waveform perforation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A plastic bag comprising: a body having a mouth, a tail end, and opposite sides extending between the mouth and the tail end, the body being composed of a plastic material and opening at the mouth; and edge configurations each extending from a mouth edge to a respective one of the sides such that the mouth edge extends by a distance which is less than a width of the body between the opposite sides, the edge configurations each having a wave pattern comprising a plurality of peaks and valleys, at least some of said peaks and valleys being closer to said tail end than are at least some neighboring ones of said peaks and valleys.
Claim 2
Dependent Claim
115 words
A plastic bag comprising: a body having a mouth, a tail end, and opposite sides extending between the mouth and the tail end, the body being composed of a plastic material and opening at the mouth; and edge configurations each extending from a mouth edge to a respective one of the sides such that the mouth edge extends by a distance which is less than a width of the body between the opposite sides, the edge configurations each having a wave pattern comprising a plurality of peaks and valleys, at least some of said peaks and valleys being closer to said tail end than are at least some neighboring ones of said peaks and valleys.
Claim 3
Dependent Claim
25 words
A bag as in claim 1, wherein the wave pattern resembles any one of a saw tooth pattern, a sinusoidal pattern and a scalloped pattern.
Claim 4
Dependent Claim

A plastic bag comprising: a body having a mouth, a tail end, and opposite sides extending between the mouth and the tail end, the body being composed of a plastic material and opening at the mouth; edge configurations each extending from a mouth edge to a respective one of the sides such that the mouth edge is between the edge configurations and extends by a distance which is less than a width of the body between the opposite sides, the edge configurations each having a wave pattern comprising a plurality of peaks and valleys; and two tabs each extending from a respective one of said edge configurations such that the wave pattern includes perforations which define a boundary of said tabs and extend from said edge configurations to respective ones of said sides.
Claim 5
Dependent Claim
133 words
A plastic bag comprising: a body having a mouth, a tail end, and opposite sides extending between the mouth and the tail end, the body being composed of a plastic material and opening at the mouth; edge configurations each extending from a mouth edge to a respective one of the sides such that the mouth edge is between the edge configurations and extends by a distance which is less than a width of the body between the opposite sides, the edge configurations each having a wave pattern comprising a plurality of peaks and valleys; and two tabs each extending from a respective one of said edge configurations such that the wave pattern includes perforations which define a boundary of said tabs and extend from said edge configurations to respective ones of said sides.
Claim 6
Dependent Claim
25 words
A bag as in claim 3, wherein the wave pattern resembles any one of a saw tooth pattern, a sinusoidal pattern and a scalloped pattern.
