Abstract
A child-resistant package in which a plug type closure has an annular seal acting radially outwardly against the internal wall of the circular opening to provide a seal. A pair of spaced fulcrums are provided by which the closure is tilted relative to the container to disengage the seal and move the closure into a position from which it can be removed from the opening in the container.
Claims12
A child-resistant package comprising:
- a container having a cylindrical inner wall forming a circular opening, a closure having an annular seal disposed in said opening and acting radially outwardly to sealingly engage said cylindrical wall of said container to close said opening, a pair of circumferentially spaced fulcrums formed within said container and below said cylindrical wall and being engageable with said closure, said spaced fulcrums defining the ends of a pivot axis disposed transversely to and at one side of said axis of said opening, means for rotating said closure about the axis of said container, said closure having a portion alignable with the circumferential space between said fulcrums on said container upon rotation of said closure to a predetermined location, said closure having portions shaped to prevent axial lifting and being tiltable in said predetermined location from a closed position to an open position upon exertion of pressure in an axial direction on said closure at a location radially outwardly of said pivot axis to move portions of said seal out of engagement with said wall for removal of said closure from said opening in said container.
