Closure with Sequenced Double Release
First Claim
1. A child-resistant closure for a container, comprising:
- an annular base that engages said container and defines an opening for accessing said container, wherein said annular base has a partial peripheral wall that extends from a first end to a second end, wherein a gap is defined between said first end and said second end;
a cap that is joined to said annular base at a hinged connection, wherein said cap can rotate about said hinged connection to cover said opening;
an activation plate mounted to said annular base within said gap with a teeter connection, said activation plate having a first section and a second section on opposite sides of said teeter connection;
a lock mechanism, controlled by said activation plate, that locks said cap over said opening and opens said cap only after both said first section and said second section of said activation plate are separately pressed in a predetermined sequence.

Abstract
A child-resistant closure for a container. The closure has a first groove and a second groove formed into a base. A cap covers an opening in the base. The cap can rotate between a closed position, a primed position and an open position. The cap has a nub that engages the first groove on the base, when in its closed position, engages the second groove on the base when in its primed position, and is free of any groove when in its open position. A mechanical activator is coupled to the base with a teeter connection. The mechanical activator displaces the cap from the closed position to the primed position when a first section of the mechanical activator is depressed. The mechanical activator displaces the cap from the primed position to the open position when a second section of the mechanical activator is depressed.

10. A child-resistant closure, comprising:
-
a base having a central opening extending therethrough, said base having a first groove and a second groove thereon at different elevations; a cap that is joined to said base at a hinged connection, wherein said cap can rotate about said hinged connection between a closed position, a primed position and an open position, said cap having a nub thereon that engages said first groove, when in said closed position, engages said second groove when in said primed position, and is free of any groove when in said open position; a mechanical activator coupled to said base with a teeter connection, said mechanical activator having a first section and a second section on opposite sides of said teeter connection that teeter about said teeter connection, wherein said mechanical activator displaces said cap to said primed position from said closed position when said first section of said mechanical activator is depressed; and
wherein said mechanical activator displaces said cap to said open position from said primed position when said second section of said mechanical activator is depressed. - View Dependent Claims (11, 12, 13)

14. A child-resistant closure, comprising:
-
a base that defines an access opening extending therethrough, said base having a first groove and a second groove thereon at different elevations; a cap that is joined to said base at a hinged connection, wherein said cap can rotate about said hinged connection over said access opening between a closed position, a primed position and an open position, wherein said cap engages said first groove, when in said closed position, engages said second groove when in said primed position, and is free of both said first groove and said second groove when in said open position. a mechanical activator coupled to said base, wherein said mechanical activator has a first section and a second section on opposite sides of a teeter connection, wherein said mechanical activator displaces said cap from said closed position to said primed position when said first section of said mechanical activator is depressed; and
wherein said mechanical activator displaces said cap from said primed position to said open position when said second section of said mechanical activator is depressed. - View Dependent Claims (15, 16, 17, 18)
