953,411. Flexible containers; container closures; skips. CONTAINER PATENT CO. G.m.b.H. Feb. 1, 1961 [Feb. 24, 1960], No. 3896/61. Headings B8D, B8H and B8T. [Also in Division F1] A collapsible container, which may be loaded and unloaded either when suspended or when resting on the ground, comprises rigid end members 1, 2 and a flexible body 3 to which the members 1, 2 are removably or permanently secured. Closable filling and discharge openings 4, 5 and suspension cables 8 are provided. The members 1, 2 may consist of wood, metal or synthetic plastics such as polyethylene, hard p.v.c., a polyester, a phenolic resin, or two or more of these plastics reinforced by glass fibre, felt or textile filaments. The body 3 may consist of one or more layers of plastics material with a textile reinforcement, the plastics being p.v.c. or artificial rubber. The container may be of oval or polygonal cross-section or in the shape of a truncated cone. An inner lining or casing, Fig. 3 (not shown) may be made of a polyamide, p.v.c., polyurethane, silicone, polyester, or artificial rubber; alternatively it may be of crepe paper coated with plastics material, or in the form of a seamless tube crimped at its ends to fit the container openings. The ends of the liner may be wrapped round a retaining member, Figs. 4 and 5 (not shown); and it may be of an elastic material which causes it to contract as the weight of the contents decreases, Fig. 6A (not shown). The contents may be evacuated by hydraulic or pneumatic means (see Division F1). The liner may be inflated by means of compressed air before the liquid cargo is filled into it; or the liquid may itself be filled under pressure. Composite end plates may be fitted, Fig. 7, the container being stackable either when filled or in its collapsed condition, Fig. 7A (not shown). Clamps 553 may secure the container when collapsed. Closures.-A plate 561 and a threaded member 560 are formed with co-operating tapering cams and cut-out portions to provide a bayonet lock assembly closing the filling opening. The plate 561 has radial ribs, Fig. 9 (not shown), to provide a hand grip for turning the plate. The assembly may be locked in position by means of a slide 566 carrying a cylindrical head 570 which engages with one of a series of notches 572, 573 in the member 560 and a ring-nut 559 respectively. The opening in the container base is closed in the same way. Specification 907,266 is referred to.
