ABSTRACT:
A snap on child resistant closure has a radial port which may be aligned with a radial port on a cooperating container neck to allow dispensing of granular or pulverulent contents. The closure has a flexible annular skirt provided with a plurality of inwardly projecting lugs. Cooperating outwardly projecting lugs on the container neck normally prevent rotation of the closure to the angular position of alignment of the radial ports. The flexible annular skirt must be squeezed and distorted to disengage the lugs, thereby permitting alignment of the ports.
