Abstract
Abstract The present invention relates generally to safety closure devices for open-ended containers, and more particularly to closure devices designed to counteract unauthorized removal thereof, as for example the removal of a bottle cap by a child. The embodiment disclosed herein includes a first closure section for permanent attachment to the open end of a container and a second closure section or cap hingedly coupled and thus shiftable with respect to the first section. Said second section is adapted in one shifted position to cover, and in another position to uncover the first closure section. The second closure section is sufficiently flexible laterally so as to become distorted in shape when opposed pressures are manually applied to the cap periphery. Means is provided for detachably interlocking first and second sections, the functioning of said means being controllable as an incident to the flexing of the second section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
185 words
A safety closure device for an open-ended container including a first section for telescopic association with a container in the vicinity of the open end thereof, means for securing said section against unauthorized axial separation with respect to a container, a second shiftable section in the form of a closure member hingedly coupled with said first section and adapted in one shifted position to cover and in another position to uncover said first section, and means providing an interference fit for detachably interlocking said first and second sections in closed position, said second section being sufficiently flexible to become distorted in shape independently of said first section in response to opposed pressures applied manually to opposite areas of the periphery thereof for releasing the interference fit between the first and second sections permitting the latter to be moved to open position, and the means for detachably interlocking said first and second sections comprising interlocking protuberances, the first section having oppositely disposed inclined surfaces adapted to be engaged by adjacent peripheral portions of the second section to cause elevation of said second section upon distortion thereof.
Claim 2
Dependent Claim
185 words
A safety closure device for an open-ended container including a first section for telescopic association with a container in the vicinity of the open end thereof, means for securing said section against unauthorized axial separation with respect to a container, a second shiftable section in the form of a closure member hingedly coupled with said first section and adapted in one shifted position to cover and in another position to uncover said first section, and means providing an interference fit for detachably interlocking said first and second sections in closed position, said second section being sufficiently flexible to become distorted in shape independently of said first section in response to opposed pressures applied manually to opposite areas of the periphery thereof for releasing the interference fit between the first and second sections permitting the latter to be moved to open position, and the means for detachably interlocking said first and second sections comprising interlocking protuberances, the first section having oppositely disposed inclined surfaces adapted to be engaged by adjacent peripheral portions of the second section to cause elevation of said second section upon distortion thereof.
Claim 3
Dependent Claim
49 words
A safety closure device for an open-ended container as set forth in claim 1, wherein means for securing the first section against axial separation includes means associated with the inner periphery of said first section for interlocking with complementary means associated with the outer periphery of a companion container.
Claim 4
Dependent Claim
39 words
A safety closure device for an open-ended container as set forth in claim 1, wherein said second section is normally circular in sahpe, and upon the manual application of opposed pressures will become distorted and assume an elliptical shape.
Claim 5
Dependent Claim
46 words
A safety closure device for an open-ended container as set forth in claim 1, wherein means is provided for securing the first section against rotation with respect to a container, said means includes longitudinal recess means associated with the inner periphery of said first closure section.
Claim 6
Dependent Claim
46 words
A safety closure device for an open-ended container as set forth in claim 1, wherein the means for securing said first section against axial separation with respect to a a container, includes an annular rib projecting radially inwardly from the inner periphery of said first section.
Claim 7
Dependent Claim
43 words
A safety closure device for an open-ended container as set forth in claim 1, wherein said means for detachably interlocking said first and second section includes arcuate protuberance means on one section for interlocking with complementary arcuate protuberance means on the other section.
Claim 8
Dependent Claim
31 words
A safety closure device for an open-ended container as set forth in claim 6, wherein one of said arcuate protuberance means is of greater arcuate extent than the other protuberance means.
Claim 9
Dependent Claim
31 words
A safety closure device for an open-ended container as set forth in claim 1, wherein said first and second closure sections are hingedly coupled and comprise a one piece plastic structure.
