摘要： A securing ring 22 is snap-fittingly engageable over and around an annular mounting flange 48 of a foldable pouring spout 40 in a container closure assembly, with a frangible connection 24 between the securing ring and a spout closure member (e.g. a screw cap 12) intact. The assembled closure assembly is snap-fittingly engageable over and around a container neck 50 which is received in a groove 52 extending circumferentially about the mounting flange. The groove is defined in part by a radially outer wall having a proximal portion 54 lying towards the pouring end of the spout and a distal end portion 56 lying away from the pouring end of the spout. The radially outer wall comprises a central flexure zone 58 of reduced radial width relative to the proximal and distal end portions, whereby the distal end portion is hingeingly deflectable between a radially outer position for extraction of the spout 40 from a mold tool, and a radially inner position for engagement in an annular undercut 60 in a radially outer surface of the container neck. When the securing ring 22 is snap-fittingly engaged over and around the mounting flange 48, the distal end portion 56 is held in the radially inner position. The distal end portion comprises a chamfer 74 at its radially inner side and which extends radially inwards towards the pouring end of the spout for guiding the closure assembly into snap-fitting engagement with the container neck.
