Decorative and aesthetic multi-part closure, caps, covers and the fabrication thereof

摘要

Rib and groove snap-type action securing elements are formed respectively on closure bases and caps so that a number of different closure caps can be disposed for co-action with a single base to fabricate a number of different closure assemblies. In one embodiment the rib is carried by a depending circumferential wall of the cap for co- action with a circumferential groove formed in the base, while in another embodiment the rib is carried by an upstanding circumferential wall of the base for co-action with a groove disposed peripherally about the cap. In other embodiments a disc-like intermediate cap is disposed between a base and a top cap formed with a surrounding depending wall with a bead along its lower edge for co-action with the lower edge of the base. In yet another embodiment the intermediate member is also formed with a depending circumferential wall terminating in a circumferential bead which co-acts with a lower edge of the base and with a groove on its outer surface that co-acts wth a bead proximate the lower edge of the top cap. In yet another embodiment the cap includes a pair of parallel disposed ribs one for co-action with a disc-like intermediate cap and one for co-action with the base member.
