Independent Claim 180 words
A pack of thermoplastic film bags, said bags being in at least approximately registration, each bag comprising a bottom, front and rear walls connected by way of gusseted side walls, a bag mouth, double film loop handles at opposite ends of the bag mouth, said handles being integral extensions of said walls; said pack having pack suspension means in association with said handles about intermediate between the top and the base of said handles; and first releasable means between the upper rear portion of a lead bag and the upper front portion of the next bag, said upper portion including the portion from just below the bag mouth to the extent of the handles, which, upon removal of said lead bag from the pack, causes an initial opening of the top portion of said next bag and second releasable means located between each rear and front wall at the lower portion of each bag near the bottom of each bag to cause a more complete opening of said next bag on removal of said lead bag by the handles thereof.
Claim 2
Dependent Claim 180 words
A pack of thermoplastic film bags, said bags being in at least approximately registration, each bag comprising a bottom, front and rear walls connected by way of gusseted side walls, a bag mouth, double film loop handles at opposite ends of the bag mouth, said handles being integral extensions of said walls; said pack having pack suspension means in association with said handles about intermediate between the top and the base of said handles; and first releasable means between the upper rear portion of a lead bag and the upper front portion of the next bag, said upper portion including the portion from just below the bag mouth to the extent of the handles, which, upon removal of said lead bag from the pack, causes an initial opening of the top portion of said next bag and second releasable means located between each rear and front wall at the lower portion of each bag near the bottom of each bag to cause a more complete opening of said next bag on removal of said lead bag by the handles thereof.
