Abstract
Abstract In an internally threaded closure for a container having an externally threaded neck, one or more ramplike ratchets are disposed on the internal thread of the closure for releasably interlocking with corresponding and mating ratchet detents disposed within the groove adjacent to the turns of the external thread on the neck of the container. The configuration of the ratchets and detents is such that the ratchets will easily slide into and out of successive detents and, thus, permits conventional closing of the container by ordinary rotation of the closure relative to the container. Reverse rotation of the closure relative to the container is prevented by corresponding locking side walls on the ratchets and detents which are in planes substantially in alignment with radii to the center of the package. The closure has a side wall and a resilient top wall. The closure is removed from the container by simultaneously rotating the closure relative to the container and pressing on the resilient top wall to dilate the side wall and disengage the ratchets from the ratchet detents. In a variational embodiment, the ratchets are disposed on the groove of the neck of the container and the ratchet detents are disposed within the lateral side of the internal thread of the cap.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
An open mouth container and safety closure cap therefor comprising in combination: a container having a neck portion provided with an external spiral thread and a groove adjacent to the turns of the spiral thread with the neck portion terminating in an opening; a cap closure for said container having a side wall and a resilient top wall, said side wall being provided with an internal spiral thread adapted to engage and ride on the external spiral thread on the neck of the container in order to threadedly secure the cap to the neck of the container; and first engaging means disposed on the internal thread of the cap, second engaging means disposed within the groove on the neck of the container, said first engaging means being adapted to releasably interlock with said second engaging means to prevent ordinary removal of the cap from the neck of the container unless force is simultaneously applied to the outer side of the resilient top wall of the cap to dilate the side wall and disengage the first and second engaging means.
Claim 2
Dependent Claim
179 words
An open mouth container and safety closure cap therefor comprising in combination: a container having a neck portion provided with an external spiral thread and a groove adjacent to the turns of the spiral thread with the neck portion terminating in an opening; a cap closure for said container having a side wall and a resilient top wall, said side wall being provided with an internal spiral thread adapted to engage and ride on the external spiral thread on the neck of the container in order to threadedly secure the cap to the neck of the container; and first engaging means disposed on the internal thread of the cap, second engaging means disposed within the groove on the neck of the container, said first engaging means being adapted to releasably interlock with said second engaging means to prevent ordinary removal of the cap from the neck of the container unless force is simultaneously applied to the outer side of the resilient top wall of the cap to dilate the side wall and disengage the first and second engaging means.
Claim 3
Dependent Claim
48 words
A structure in accordance with claim 1 wherein said first engaging means is at least one protuberance extending laterally from the internal thread of the cap and said second engaging means is at least one corresponding and mating detent in the groove on the neck of the container.
Claim 4
Dependent Claim
48 words
A structure in accordance with claim 1 wherein said first engaging means comprises a plurality of protuberances extending laterally from the internal thread of the cap and said second engaging means comprises a plurality of corresponding and mating detents in the groove on the neck of the container.
Claim 5
Dependent Claim
46 words
A structure in accordance with claim 1 wherein said first engaging means is a ramplike ratchet extending laterally from the internal thread of the cap and said second engaging means is a corresponding and mating ratchet detent in the groove on the neck of the container.
Claim 6
Dependent Claim
50 words
A structure in accordance with claim 1 wherein the first engaging means comprises a plurality of ramplike ratchets extending laterally from the internal thread of the cap and said second engaging means comprises a plurality of corresponding and mating ratchet detents in the groove on the neck of the container.
Claim 7
Dependent Claim
52 words
A structure in accordance with claim 1 wherein the outer wall of the neck portion of the container coverges towards the container opening at an angle up to about 15.0* with respect to the vertical and the inner wall of the cap converges towards the cap top wall at a corresponding angle.
Claim 8
Dependent Claim
96 words
A structure in accordance with claim 1 wherein the first engaging means is provided with a locking side wall which is in a plane substantially in alignment with a radius to the center of the cap and the second engaging means is provided with a corresponding locking side wall which is in a plane substantially in alignment with a radius to the center of the neck of the container, said locking side walls of said first and second engaging means cooperating to prevent disengagement of the cap from the neck of the container by simple rotation.
Claim 9
Dependent Claim
54 words
A structure in accordance with claim 1 wherein the second engaging means is at least one protuberance extending laterally from the groove on the neck of the container and the first engaging means is at least one corresponding and mating detent disposed within the laterally extending side of the internal thread of the cap.
Claim 10
Dependent Claim
55 words
A structure in accordance with claim 1 wherein the second engaging means comprises a plurality of protuberances extending laterally from the groove on the neck of the container and the first engaging means comprises a plurality of corresponding and mating detents disposed within the laterally extending side wall of the internal thread of the cap.
Claim 11
Dependent Claim
56 words
A structure in accordance with claim 1 wherein the second engaging means is at least one ramplike ratchet extending laterally from the groove on the neck of the container and the first engaging means is at least one corresponding and mating ratchet detent disposed within the laterally extending side of the internal thread of the cap.
Claim 12
Dependent Claim
56 words
A structure in accordance with claim 1 wherein the second engaging means comprises a plurality of ramplike ratchets extending laterally from the groove on the neck of the container and the first engaging means comprises a plurality of corresponding and mating ratchet detents disposed within the laterally extending side of the internal thread of the cap.
