Abstract

1,072,856. Block – bottom plastics bags. UNION CARBIDE CORPORATION. Nov. 22, 1963 [Dec. 26, 1962], No. 46145/63. Heading B8K. A block-bottom welded plastics bag is formed from a tubular blank 30 (Fig. 6) formed with at least two cut-outs 31 (311) and with slits 32 (321), 33 (331) deeper than the cut-outs. In the arrangement of Fig. 6 the end tabs 36, 37 are folded in and welded to one another, as at 38, 39 in Fig. 7, and then welded also at 40, 41 to the walls of the bag before the side flaps 34, 35 are folded over and welded together to form a hand hold. In an alternative arrangement (Fig. 1, not shown) four cut-outs (2), (21), (3), (31) are provided thus forming on the end tabs (A), (A1) flaps which can be folded outwardly as at (13), (Fig. 2, not shown) before the side flaps (12), (11) are overlapped to be welded together and to the flaps (13). In this construction the end tabs A, A1 are welded at (16) … (19) to the side walls of the bag. Parts of the side walls are preferably folded in with the side flaps. The side flaps 34, 35 may be omitted from the construction of Figs. 6 and 7, or the welds 40, 41 may be omitted. The side flaps 34, 35 need not overlap, but may be welded instead to the end tabs. The omission of the welds 40, 41 may provide three openings, and these may be closed after the bag is filled by welding a strip of plastics film over the opening. Holes at the ends of the slits 4, 5 etc. may prevent tearing.
