Abstract

Abstract A cap closure and peripheral neck for any container which is child resistant since it requires a combination downward and twisting motion to either open or close the cap closure. A sloping camming surface in the peripheral groove portion of the cap assists in the closing action. The cap may be provided with a finger tab that projects upwardly from a dished central portion of the cap closure, thereby making it more difficult for children to grasp and open and close the cap closure. A resilient flange on either the cap or container biases said cap in an upward direction. An abutment stop in the neck portion prevents overstressing the resilient flange and indicates when to rotate on opening. A vertical stop in cap indicates when cap is ready to be totally removed.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 97 words
A closure cap assembly for a container, comprising a pair of mating members, one of the members being provided with elongated, lateral extending grooves, a camming surface in each of said grooves, a locking slot adjacent to said camming surface, an abutment surface on said one member serving as a positive stop for said other member when the latter is depressed downwardly, and substantially vertical walls at opposite ends of said grooves serving as positive stops when said cap is rotated in either direction, and said projections being cammed on said camming surfaces into adjacent locking slots.
Claim 2
Dependent Claim 97 words
A closure cap assembly for a container, comprising a pair of mating members, one of the members being provided with elongated, lateral extending grooves, a camming surface in each of said grooves, a locking slot adjacent to said camming surface, an abutment surface on said one member serving as a positive stop for said other member when the latter is depressed downwardly, and substantially vertical walls at opposite ends of said grooves serving as positive stops when said cap is rotated in either direction, and said projections being cammed on said camming surfaces into adjacent locking slots.
Claim 3
Dependent Claim 29 words
A closure cap assembly as claimed in claim 1, wherein said one member is located in the neck of the container while said other member is the closure cap.
Claim 4
Dependent Claim 21 words
A closure cap assembly as claimed in claim 2, wherein said one member is molded in the neck of said container.
Claim 5
Dependent Claim 26 words
A closure cap assembly as claimed in claim 2, wherein said closure cap is dished, and a finger piece in said dished portion projects upwardly therefrom.
Claim 6
Dependent Claim 30 words
A closure cap assembly as claimed in claim 2, wherein bottom outer edge of said closure cap engages said abutment surface in said neck to limit downward motion of cap.
Claim 7
Dependent Claim 44 words
A closure cap assembly as claimed in claim 2, wherein said closure cap is provided with lateral grooves, the leading and trailing edges of which limit the lateral motion of said cap in either direction by interaction with sides of projections in said neck.
Claim 8
Dependent Claim 36 words
A closure cap assembly as claimed in claim 5, wherein said neck of the container is provided with an annular groove in which the edge of said resilient flange fits to render the assembly substantially waterproof.
Claim 9
Dependent Claim 23 words
A closure cap assembly as claimed in claim 4 wherein said finger piece extends up to the top surface of said closure cap.
