Abstract
Abstract A child resistant closure and container in which the safety closure cap fits within the interior of the top of the container. The inner periphery of the container is provided with inwardly projecting locking bars that fit into corresponding locking slots in the cap. The latter is further provided with an upwardly projecting finger piece that requires a substantial amount of prehensile strength to manipulate. The closing flange on the bottom surface of the cap, or on the container, is resilient, thereby normally biasing said cap in an upward direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
A child resistant safety cap closure and container comprising a plurality of locking projections protruding inwardly from an inner-peripheral surface of said container adjacent to the top thereof, said cap closure fitting within the inner periphery of said container and having a plurality of through slots and a plurality of locking slots in the outer periphery thereof, and resilient sealing means acting to bias said closure away from the container when said closure has said through slots aligned over corresponding locking projections and said closure is subjected to an axial force in the direction of said container against said resilient means to a position whereby said projections pass through said through slots, said closure being thereafter rotated to a position whereby said locking projections are located over said locking slots, and said locking projections are urged into said locking slots by said resilient sealing means when said axial force on said closure is removed.
Claim 2
Dependent Claim
154 words
A child resistant safety cap closure and container comprising a plurality of locking projections protruding inwardly from an inner-peripheral surface of said container adjacent to the top thereof, said cap closure fitting within the inner periphery of said container and having a plurality of through slots and a plurality of locking slots in the outer periphery thereof, and resilient sealing means acting to bias said closure away from the container when said closure has said through slots aligned over corresponding locking projections and said closure is subjected to an axial force in the direction of said container against said resilient means to a position whereby said projections pass through said through slots, said closure being thereafter rotated to a position whereby said locking projections are located over said locking slots, and said locking projections are urged into said locking slots by said resilient sealing means when said axial force on said closure is removed.
Claim 3
Dependent Claim
27 words
The combination as claimed in claim 1 wherein said through slots and locking slots are located in alternating sequence around the outer periphery of said cap closure.
Claim 4
Dependent Claim
23 words
The combination as claimed in claim 1 wherein said resilient sealing means is an integral flange which depends downwardly from said cap closure.
Claim 5
Dependent Claim
31 words
The combination as claimed in claim 2 wherein said flange is provided with a portion that engages a wall of the inner peripheral surface of said container in a watertight construction.
Claim 6
Dependent Claim
30 words
The combination as claimed in claim 2 wherein the inner peripheral surface of said container is provided with a circumferential groove, and said flange is firmly engaged in said groove.
Claim 7
Dependent Claim
18 words
The combination as claimed in claim 1 further comprising an upstanding finger piece mounted on said cap closure.
Claim 8
Dependent Claim
27 words
The combination as claimed in claim 1 wherein said resilient sealing means is provided on said container on a plane below the plane of said locking projections.
Claim 9
Dependent Claim
22 words
The combination as claimed in claim 7 wherein said resilient sealing means is an integral part of said container and projecting inwardly.
Claim 10
Dependent Claim
39 words
The combination as claimed in claim 8 wherein said cap closure is provided with a downwardly projecting annular ring that engages with said resilient sealing means on said container in a sealing manner to thereby provide a waterproof construction.
Claim 11
Dependent Claim
31 words
The combination as claimed in claim 8 wherein said cap closure is provided with a bevelled surface, said container having an internal second bevelled surface corresponding to said first bevelled surface.
Claim 12
Dependent Claim
34 words
The combination as claimed in claim 2 wherein said through slots are each provided with an edge tapering angularly upwardly which automatically depresses said closure cap when the same is rotated in said container.
