A thermoformed container lid 26 for fixing to a container body 27 has a peripheral skirt portion 28 of axial length substantially equal to that of a container skirt 29 to permit fusion of the free edges of the skirt together to prevent illicit removal of the lid, and the lid skirt has a removable band 22 therearound formed by localised incision(s) or material thinning. Apparatus (Figs. 11, 13) for applying the lid to a container includes means to press the lid onto the body to bring the free edges of the lid and body skirts into the same plane, and means to apply heat and pressure to the free edges to fuse them together. <IMAGE> |
