Abstract

A carrier bag for transporting granular foods and the like. The bag includes two main panels connected by two side panels. One of the side panels includes a bellows having a fold line and a folding zone that is defined by the immediate area surrounding the fold line. The bag also includes a top edge which defines an opening to the bag. The opening is closed by adhering together the two main panels close to and along the entire length of the top edge. Finally, a pull-tab is provided that is integrally formed with the bellows and projects out from the top edge.

Claims

1. A carrier bag comprising:

two main panels;

two sides connecting said main panels, one of said sides including a bellows having a fold line and a folding zone defined by the area of the bellows immediately surrounding said fold line;

uppermost ends of said main panels and said sides sealed together along their entire lengths to define a top edge of said bag;

a top edge portion comprised of portions of the uppermost ends of said panels and said bellows, said top edge portion defining an opening that is closed by peelably adhering the portions of the uppermost ends of said panels to said bellows; and

a pull-open tab integrally formed with said bellows for opening said bellows, said tab projecting out vertically from said top edge and positioned adjacent said fold line of said bellows, wherein the width of said tab is restricted to said folding zone of said bellows.
