1530165 Container closures REFIL AG 17 Dec 1975 [17 Dec 1974 31 Oct 1975] 51653/75 Heading B8T A container closure comprises (a) a cap having a top wall and a skirt which has an annular bead projecting inwardly from its inner surface; (b) a sealing element on the inner surface of the top wall of the cap; (c) a lifting element integral with the cap for finger actuation; (d) at least one slot in the cap skirt adjacent the lifting element, each slot extending from the lower rim of the skirt transversely to the plane of the rim through the annular bead and upwardly beyond it to permit the cap skirt to splay on being mounted on a container; and (e) at least one elastically resilient bridging member for each slot and which projects outwardly of the cap skirt on both sides of the respective slot, each bridging member being tautly stretched tangent. ially to the cap skirt when the closure is applied to a container whereby counteracting splaying of the slot it bridges. In the embodiment of Fig. 6 the cap skirt 41 has a single slot 27 bridged by a member 46. Splaying of the slot is counteracted by cooperation between the ramps 42, 43 on either side of the slot 27 and the side surfaces 47a and bottom surface 47b of a recess 47 in the member 46. The closure of Fig. 13 has two slots 82, 83 in its skirt 81, each slot being bridged by members 84, 85 respectively. A detailed description of constructions of the sealing element is given with reference to Figs. 18 and 19 (not shown). Tamper-indicating means may be positioned to bridge a slot and be ruptured by the first use of the lifting element.
