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.

A child resistant package comprising, in combination, a container having an annular neck and a closure fitted on said neck, said container neck having a radially disposed discharge port and a downwardly facing shoulder, said closure comprising a panel section and an annular skirt depending from the periphery of said panel section molded from an elastomeric material, means on the skirt of said closure for engaging said shoulder to retain said closure on said neck against axial displacement but permitting rotational movement of said closure relative to said neck, said closure having a radial dispensing port formed in said annular skirt, a pair of diametrically opposed cooperating detent and notch means formed on the said annular skirt of the closure and on said container neck to secure said closure to said container neck in a position where said radial ports are mis-aligned, said annular skirt of said closure being radially deformable by manual application of a squeezing force intermediate said pair of detent and notch means to release said detent from said notch to permit rotational alignment of said closure dispensing port with said container neck dispensing port, an upwardly facing camming surface outwardly projecting from said neck, and a downwardly facing camming surface inwardly projecting from said skirt, said camming surface being engageable only when said elastomeric skirt is manually squeezed to move said downwardly facing camming surface radially inwardly, at least one of said camming surfaces having a generally helical shape, whereby rotation of said closure relative to said neck while said camming surfaces are engaged will cam said closure upwardly off said neck.
