ABSTRACT:
The Assembly has a circular platform, which is threaded about its periphery, and has an upstanding stub about which to set a sleeve-type or cylindrical seal, as well as an arcuately cross-sectioned groove in circumscription of the base of the stub. A cup-shaped closure, having a circular wall, and threaded on the inner wall surface, threadedly engages the threaded periphery of the platform. Upon the platform and closure being threadedly engaged, the closure forces the seal along the stub until an inner end of the seal enters the groove and takes on a proper flare. The closure protects the seal from shipping damage.
