1,113,747. Container closures. L. ASSALIT. 13 Oct., 1966 [26 Oct., 1965], No. 45794/66. Heading B8T. [Also in Division F1] A closure for a circular opening in a container comprises a frusto-conical peripheral outer face 9, 9bis, having either a recess 5, Fig. 1, to locate round a shoulder 7 on the opening, or else a ridge 6, Fig. 2, to locate in a recess 8 in the opening. The closure is sprung into the opening due to the flexibility of the closure and/or container. The closure may be conical (10), Fig. 4 (not shown), and may carry a valve (14). The container and end closure may be either both of flexible plastics material or one of plastics and the other of metal.
