Abstract

A closure cap (1) of the present invention is provided for closing a tube (3). The cap has a skirt (15) which, when installed on the tube, extends from the end of the tube along the outside of the outside surface of the tube wall, an end closure (13) which extends across the end of the tube and closes off the end of the tube, and an inner flange (17) integral with the skirt and with the end closure. The inner flange is concentric with the skirt such that the end of the tube is received between the skirt and the inner flange. The cap further has a wall (19) integral with the inner end of the flange and integral with the end closure for connecting the inner end of the inner flange and the end closure. A flexible connection (23) is provided between the skirt and the inner flange which permits flexing of the inner flange relative to the skirt upon installation of the cap on the tube thereby to enable installation of the cap on the tube substantially without deformation of the tube. The wall and the end closure apply a radially outward biasing force on the inner flange thereby to grip the tube between the inner flange and the skirt so as to hold the cap on the tube.
