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 top wall 18 of the closure.

A closure and a container having a moisture tight sealing engagement with each other, said closure being either a child resistant or non-child resistant closure, comprising: a container having a side wall, an upper end with an open mouth over which said closure is received, and locking members on said container adjacent said upper end; an interior wall on said side wall of said container having detent projections extending inwardly into the hollow interior of the container, ends on the detent projections being spaced from one another in a circumferential direction and to define spaces between adjacent projections; a closure having a top wall adapted to extend across the mouth of said container and a depending skirt wall, a sealing plug extending downwardly from said top wall and having a depending wall for insertion into said open mouth of said container; said depending wall having an outwardly projecting annular sealing surface, the annular sealing surface having a diameter substantially larger than an inner diameter defined by the projections, portions of the annular sealing surface expanding into the spaces between adjacent projections as the sealing surface is being pushed down past the projections or is being pulled upwardly past the projections, said sealing surface extending below said detent projections to hold said closure onto said container and to engage said interior wall below said projections to provide a moisture tight sealing engagement of said closure with said container, said projections holding the closure on the container.
