Abstract
A roll of plastic bags, wherein the action of tearing a bag off the roll opens each bag. The present invention interrupts or vitiates the static cling that prevents the bag from being opened without licking or moistening fingers. A small adhesive patch is glued on the perforation line between bags, spanning both bags on the roll. Tearing off a bag causes the patch to rip out a small portion of the bag's mouth. Static cling is interrupted, and the bag can be opened.
Claims7
A roll of self-opening bags, comprising:
- a plurality of identical plastic bags wound into the roll,
- each said bag of said plurality of plastic bags comprising:
- a length and a width,
- a bottom portion, wherein said bottom portion comprises a weld across said width perpendicular to said length, and
- a top portion, wherein said top portion comprises a mouth adapted to be opened,
- wherein each of said bags of said plurality of plastic bags are separated by a perforation line, said perforation line being located between said bottom portion of one said bag of said plurality of plastic bags and said top portion of an immediately-subsequent said bag of said plurality of plastic bags,
- wherein said perforation line facilitates a removal of said one said bag from said immediately-subsequent said bag, and
- an adhesive patch with a length and a width, adhered onto said perforation line, said adhesive patch adhered simultaneously to said weld of said one said bag and said mouth of said immediately-subsequent said bag,
- wherein said removal of said one said bag from said immediately-subsequent said bag causes said adhesive patch to tear out a part of said mouth of said immediately-subsequent said bag, thereby disrupting cling forces preventing said mouth from opening.
