Abstract
A cap and tube assembly comprising a tube having a neck ending in a discharge end having an outwardly extending stem frangibly supported at a point recessed from the outer terminal end of the neck to define an outlet when the stem is removed. A cap sized to slightably fit the neck and including an inwardly facing stem engaging the socket is provided, positively locking the stem in the socket in a predetermined position. The cap is located at a first position where the stem and socket are spaced apart and at a second position defined by the predetermined position of a stem locking device. The stem is frangibly supported on the discharge end by an annular thin wall and a plurality of axially extending bridges for resisting axial movement of the stem and permitting rotational movement to rupture the thin wall to form an outlet for the tube.
