A reversible child resistant closure having a child resistant and a non-child resistant mode of use. The closure is characterized by its low profile and tab that extends outwardly from the closure; this tab being engageable from below when closure is rotated into the appropriate position on the container. An upwardly extending relatively low annular rib is provided on the roof of the closure which serves as the means by which the closure is engaged by the container neck when the closure is inserted into the container neck in its non-child resistant mode.

A reversible child resistant snap-on closure; said closure being adapted to serve as a child resistant closure when applied to a container in a first upright position while being adapted for ready removal by an adult from a container when applied to said container in a second inverted position, said closure being a low profile flexible snap-on closure for a container having a neck, said closure having a roof, a skirt and a lower marginal surface having an internal diameter of substantially uniform size; said skirt being provided on the internal surface thereof with means for engaging a portion of the neck of said container; said snap-on closure being provided with a tab extending outwardly from said lower marginal surface and having a lower surface which is in substantially the same plane as the lower marginal surface of said closure; said skirt being tapered downwardly and outwardly from said closure roof to the outer circumference of said lower marginal surface, the shortness of said skirt and its taper being such as to make it difficult for a child to get its teeth on it when the closure is in position on a bottle in the child resistant position; said closure also being provided with an annular ridge extending upwardly from the top of said closure roof, said annular ridge being slanted downwardly and outwardly when said closure is held in its inverted position, said annular ridge being adapted to be compressed inwardly when applied to a container so that it will engage the inner wall of the neck of said container in a snap-fit relationship.
