Abstract
A roll of self-opening plastic bags separated by perforations, each bag having an openable mouth at its top and a weld at its bottom. A skirt of material extends from the weld of one bag to the perforation between the end of the skirt and the mouth of an adjacent bag. A patch is bonded to the skirt of one bag, over the perforation, and to the mouth of the adjacent bag. During separation of bags, the patch creates a gripping tab on the adjacent bag's mouth and breaks cling forces between the mouth's opposing walls, resulting in a bag that can be opened without licking fingers, while wearing gloves, or for users with reduced hand mobility.
Claims8
A roll of self-opening bags, comprising:
- a plurality of plastic bags wound into said roll,
- each said bag of said plurality of plastic bags comprising:
- a length and a width,
- a top portion, wherein said top portion comprises a mouth adapted to be opened, and
- a bottom portion, wherein said bottom portion comprises
- a weld across said width, and
- a skirt portion between said weld and said top portion of an immediately-adjacent bag of said plurality of plastic bags,
- wherein each of said bags of said plurality of plastic bags is separated by a perforation line, said perforation line being located between said skirt portion of said one said bag of said plurality of plastic bags and said top portion of said immediately-adjacent said bag of said plurality of plastic bags,
- wherein said perforation line facilitates a removal of said one said bag from said immediately-adjacent said bag, and
- an attachment element with a length and a width, bonded onto said skirt portion, over said perforation line, and onto said top portion of said immediately-adjacent said bag,
- wherein said removal of said one said bag from said immediately-adjacent said bag causes said attachment element to tear out a part of said skirt portion of said one said bag, said attachment element thereby forming a tab portion projecting from said top portion of said immediately-adjacent said bag.
