## CPC

- B65D 83/08: for dispensing thin flat articles in succession (for surgical scalpel blades A61B17/3215)
- B65D 33/001: {Blocks, stacks or like assemblies of bags}
- B65D: CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR FITTINGS THEREFOR; PACKAGING ELEMENTS; PACKAGES

## 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

### Claim 1

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 (depends on 1)

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 3

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 4 (depends on 3)

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.
