Class 44 An end stop seal 48, for a sealing closure as described in Specification 834,430, comprises a U-shaped flexible sealing body 49 embracing one end 18 of the closure, and integral with the ends of sealing elements 22, 23, which extend along and are bonded to the upper faces of the teeth 29 of a sliding clasp fastener; the sealing body having a plurality of sealing ribs 53, 54 projecting from its upper surface and which press outwardly against an inner seating surface of the fastener slider 56 when in the closed position of the sealing closure. The legs 50, 51 of the U-shaped body are embraced, in the closed position of the closure, by the upper plate flanges of the slider 56, and are thereby urged towards each other so that the broad ends 60, 61 and 64, 65 of the ribs 53, 54 respectively abut each other. A plate 68, Fig. 9, is bonded to the underside of the U-shaped body 49 and to the adjacent parts of the fabric stringers 24, 25; and prongs 72, 73 mesh between the end teeth of the fastener to ensure correct alignment. |
