Abstract
A closure adapted to be applied to a neck of a vessel or container so as to seal a comparatively wide mouth in said neck has a rim or skirt which is divided up into a plurality of sections by slits between the sections depending from a lid portion of the closure and a stressing or tensioning band placed around the rim, the arrangement being such that there is at most only slight engagement between corresponding screw threads or the like on the neck and in the skirt when the closure is applied to the neck, full sealing engagement between the said screw threads being produced by tensioning of said band after the closure is in position on the neck, such tensioning causing the initially radially outwardly splayed said sections to be pulled radially inwardly on to the neck. The vessel and closure are preferably of thermoplastic material. Preferably tensioning of said band also causes the closure to move axially into more intimate contact with the vessel to compress a sealing ring and thereby improve the seal therebetween.
