Abstract
443,920. Paper bags. PAPER SACKS, Ltd., and ROBINSON, F. G., 1, Redcliffe Street, Bristol. Sept. 11, 1934, No. 26099. [Class 94 (ii)] A block-bottomed bag, preferably of the multi-ply type, is provided with triangular extensions 6a at the corners formed by folding end flaps 9, 10 inwardly and outwardly and securing the side flaps 7, 8 together over the outwardly folded portions of the end flaps. The respective sheets 1, 2, 3, 4 are cut from webs by parallel and oblique cuts and assembled to present headings a ... d; a<1>. . . d<1> on the two sides, the oblique cuts intersecting at joints 6 on the longitudinal fold lines. The nested tube is formed, Fig. 3, by gumming the respective longitudinal margins together, and the top opened in the usual manner, Fig. 5, to present side flaps 7, 8 and end flaps 9, 10. The points 6 are then lifted and turned outwardly until they coincide with the corners 6b, thereby forming triangular pockets 6a, the headings a ... d; a<1> ... d<1> being gummed together as the side flaps 7, 8 are turned inwardly to cover the doubly folded end flaps. The tube may be gussetted. For forming a valve in one or two corners, the tube is slit longitudinally and the point 6c is covered by a gummed U- shaped strip 12 embracing the end flap 9a on both sides. The side flaps 7a, 8a are then folded in about lines III ... III to include a part of the end flap 9a. In a modification, Figs. 17, 19, 20, the assembled sheets are notched at 6e, or the tube may be cut off at each corner at 45‹, the tube end being opened, Fig. 19, presenting side flaps 7c, 8c and end flaps 10b. The point 6e is then turned upwardly and outwardly to present a triangular pocket 6f, the respective plies on either side flap 7c, 8c being glued and interleaved. Specification 443,950 is referred to.
