Abstract

560,708. Paper &c. bags. DICKINSON & CO., Ltd., J., and SKEINS, D. M. March 5, 1943, No. 3647. [Class 94 (ii)] A paper &c. bag has an extended rear wall b provided on the outer side with an adhesive strip c of thermoplastic &c. near the edge while the front wall has a similar strip c<1> spaced from the edge, so that when the extension b is folded twice, the two strips come together and seal the bag. During the first folding of b, a portion f of the front wall is folded, so that when b is folded a second time, a pocket h is enclosed.
