1,243,393. Closures for containers. DART INDUSTRIES Inc. 7 Aug., 1968 [10 Aug., 1967], No. 37627/68. Heading B8T. [Also in Division A4] A closure 11 comprises an imperforate central wall 14 and an integrally formed peripheral sleeve 15 enabling the closure to be fitted in a first and in a second, inverted position on a rim defining an opening to seal the opening. As shown, the closure forms a snapfit by means of beads 18 on the rim 26 of a jelly-mould 12. The wall 14 is provided with contours (22) of polyangular configuration, Figs. 1 and 2 (not shown), so as to produce a different pattern on the moulded article in the two positions of the closure. The mould 12 may be provided with a removable closure (13) at the other end, Fig. 6 (not shown).
