Abstract
A tamper evident closure assembly is for use with a fitting having an outer sidewall with internally-directed threads, externally-directed splines, and an open post. The closure assembly includes a cap, a collar, and a frangible attachment coupling the cap and collar. The cap, collar, and frangible attachment are formed integrally as an integral unit. A radial lug on the cap engages with the fitting threads. A pawl on the collar allows rotation of the integral unit on the fitting in a first rotational direction and prevents rotation in a second rotational direction. Application of the integral unit to the fitting engages the radial lug with the threads on the fitting and the post and the cap form a fluid seal. Tampering with the integral unit when the integral unit is applied to the fitting severs the frangible attachment, thereby defining the cap and collar as separate pieces.
