Abstract

Abstract A safety package structure is provided comprising an externally threaded container and closure assembly therefor which includes an internally threaded cap for the container and a cover for the cap. The cover and cap are provided with corresponding and mating guide members to align the assembly, to permit longitudinal movement of the cover with respect to the cap and to impart torque to the cap. Yieldable means are disposed between the cover and the cap to maintain the cover in an axially compressible, predetermined uncompressed position. The cap side wall is provided with transverse apertures positioned on the path of and extending through the internal thread. Longitudinally resilient, ramplike ratchets are laterally disposed on the inner surface of the cover side wall so as to extend through the cap side wall apertures for releasably interlocking with corresponding detents in the thread groove on the neck of the container when the cover is in the uncompressed position. The configuration of the ratchets and detents is such that the ratchets will easily slide into and out of successive detents and, thus, permit conventional closing of the container by ordinary rotation of the closure assembly relative to the container. Reverse rotation of the closure assembly 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 assembly is removed from the container by simultaneously rotating the assembly and pressing on the cover top wall to move the cover to a compressed position whereby the ratchets, which follow the movement of the cover side wall, are withdrawn from the detents. Upon release of the pressing force, the yieldable means bias the cover to its original uncompressed position which realigns the ratchets to releasably interlock with the detents when the closure assembly is threadedly secured to the container.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 461 words
An open mouth container and safety closure assembly therefor comprising in combination: a container having an arcuate neck portion terminating in an opening with the outer surface of the neck portion being provided with an external spiral thread which defines a thread groove adjacent to said external thread; an arcuate cap and cover assembly for said container; said cap having a top wall and a continuous side wall depending from the peripheral edge of the top wall, with each wall having an outer surface and an inner surface and the inner surface of the cap 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; said cap side wall being provided with transverse apertures positioned on the path of and extending through said internal thread for accommodating first engaging means as hereinafter defined; said cover having a top wall and a continuous side wall depending from the peripheral edge of the top wall, with each wall having an inner surface and an outer surface and said cover being adapted to fit over said cap in a longitudinal, slidable relationship; first guide means assocated with the outer surface of the cap side wall, second guide means associated with the inner surface of the cover side wall, said first and second guide means being adapted to cooperatively engage to align the cap and cover assembly, to permit longitudinal movement of the cover with respect to the cap and to impart torque to the cap; yieldable means are disposed between the top wall of the cover and top wall of the cap to maintain the cover in an axially compressible, predetermined uncompressed position with respect to the cap, said yieldable means permitting said cover to be axially moved towards said cap from said uncompressed position to a compressed position upon application of force to the outer surface of the cover top wall and said yieldable means biasing said cover to its original uncompressed position upon release of said force; first resilient engaging means associated with the inner surface of said cover side wall and positioned to extend through the transverse apertures within the side wall of the cap when the cover is in the uncompressed position, second engaging means associated with the thread groove on the neck of the container, said first and second engaging means being adapted to releasably interlock when the cover is in the uncompressed position to prevent ordinary removal of the cap and cover from the container unless force is simultaneously applied to the cover to move the same to the compressed position and thereby disengage the first and second engaging means.
Claim 2
Dependent Claim 461 words
An open mouth container and safety closure assembly therefor comprising in combination: a container having an arcuate neck portion terminating in an opening with the outer surface of the neck portion being provided with an external spiral thread which defines a thread groove adjacent to said external thread; an arcuate cap and cover assembly for said container; said cap having a top wall and a continuous side wall depending from the peripheral edge of the top wall, with each wall having an outer surface and an inner surface and the inner surface of the cap 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; said cap side wall being provided with transverse apertures positioned on the path of and extending through said internal thread for accommodating first engaging means as hereinafter defined; said cover having a top wall and a continuous side wall depending from the peripheral edge of the top wall, with each wall having an inner surface and an outer surface and said cover being adapted to fit over said cap in a longitudinal, slidable relationship; first guide means assocated with the outer surface of the cap side wall, second guide means associated with the inner surface of the cover side wall, said first and second guide means being adapted to cooperatively engage to align the cap and cover assembly, to permit longitudinal movement of the cover with respect to the cap and to impart torque to the cap; yieldable means are disposed between the top wall of the cover and top wall of the cap to maintain the cover in an axially compressible, predetermined uncompressed position with respect to the cap, said yieldable means permitting said cover to be axially moved towards said cap from said uncompressed position to a compressed position upon application of force to the outer surface of the cover top wall and said yieldable means biasing said cover to its original uncompressed position upon release of said force; first resilient engaging means associated with the inner surface of said cover side wall and positioned to extend through the transverse apertures within the side wall of the cap when the cover is in the uncompressed position, second engaging means associated with the thread groove on the neck of the container, said first and second engaging means being adapted to releasably interlock when the cover is in the uncompressed position to prevent ordinary removal of the cap and cover from the container unless force is simultaneously applied to the cover to move the same to the compressed position and thereby disengage the first and second engaging means.
Claim 3
Dependent Claim 51 words

Claim 4
Dependent Claim 61 words
A structure in accordance with claim 1 wherein said first engaging means comprises a plurality of protuberances extending laterally from the inner surface of the cover side wall, and said second engaging means comprises a plurality of corresponding and mating detents in the thread groove on the neck of the container, and said cap includes corresponding transverse apertures for said protuberances.
Claim 5
Dependent Claim 49 words
A structure in accordance with claim 1 wherein said first engaging means is a ramplike ratchet extending laterally from the inner surface of the cover side wall and said second engaging means is a corresponding and mating ratchet detent in the thread gRoove on the neck of the container.
