Abstract:
1. A push and turn safety closure and container combination, comprising: a container having a depending substantially cylindrical container neck with an outer surface; a closure having a substantially round top wall and a depending substantially cylindrical side wall with an inner surface; said container neck outer surface having at least one lug receiving recess therein, said at least one lug receiving recess defined by a bottom surface connecting two opposing lateral interior surfaces that face inwardly towards each other, said at least one lug receiving recess having a first circumferential length between said two opposing lateral interior surfaces; said closure side wall inner surface having at least one lug projecting therefrom of a second circumferential length, said at least one lug being engageable with said at least one lug receiving recess; a spring member to bias said closure away from said container neck; and at least one stacking lug depending outward from said container neck outer surface or depending inwardly from said closure inner surface; said closure is in a stacking position when said at least one lug engages said bottom surface of said at least one lug receiving recess and said at least one stacking lug having a mating surface axially aligning with and engages a mating surface on the other of said container neck outer surface or said closure inner surface thereby substantially preventing axial movement of said closure in both upwardly and downwardly directions while in said stacking position relative to said container and absorbing axial loads on said closure; said mating surface of said at least one stacking lug having a third circumferential length; said first circumferential length of said at least one lug receiving recess being at least the sum of said second and said third circumferential lengths thereby allowing said at least one lug to laterally disengage from said stacking position while remaining within said at least one lug receiving recess.
