Abstract
A moisture proof vial and closure system are provided which may be used in a child-resistant mode or in a non-child resistant mode. In the child resistant mode locking lugs 22 on the closure are interlocked with bayonnet slots on the vial. A non-child resistant operation in a moisture proof system may be achieved by leaving the locking lugs 22 off of the closure skirt wall 20 and by adding a detenting means 51 inside of the container to engage and hold a sealing plug 39 against sliding outwardly of the container because of the lack of locking lugs on the closure 10A. A simple push inward will force the sealing plug 39 home to its sealing position to seal the medicine in the vial, and a simple pull on the closure to pull the fitment from the detenting means is needed to remove the closure. The preferred detenting means 51 is in the form of radially inwardly directed projections 52 formed on the interior container wall to abut and restrain the sealing plug against inadvertent sliding from the container. The sealing bead 50 on closure 10B is carried on sealing plug 39 which is formed on a discrete and separable fitment 40. For the closure 10A, the sealing plug 39 is integral with the …
