Abstract
Abstract An embodiment of the invention disclosed herein comprises a plastic bag construction having tie portions formed as an integral part of the bag which are used to close the top of the bag when filled. The bag is formed of a flattened flexible plastic tube having front and back panels and folded in portions extending along the side edges of the panels. A weld is formed along the bottom edges of the panels to close the bag and a weld is formed along the top edges of the panels to hold together the front and back panel portions which form the tie portions. A struck out portion is formed through the front and back panels near the top edges thereof and the material between the struck out portion and the top edges of the panels will form the integral tie portions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A bag construction composed of weldable sheet material in the form of a flattened flexible plastic tube having front and back panels and folded in portions extending along the side edge of said panels, a weld formed along the bottom edges of said panels and said folded in portions to form a closed bottom for the bag, a struck out portion through both front and back panels near the top edges thereof but spaced therefrom sufficient to form a tie portion extending across the top of the bag, said struck out portion passing through the innermost portions of said folded in portions to form diametrically opposed handles for the bag, and a tear line formed through said tie portion to allow pulling apart thereof into two lengths to be tied together for closing off the top of the bag so formed.
Claim 2
Dependent Claim
141 words
