Oversized safety cap

Claim 2

A safety cap forming a closure member for a container having an integral bottom, continuous sidewall and annular upper shoulder extending up to a neck portion whose upper end forms the opening to said container, said neck including thread means formed thereon adjacent to said upper end opening, a cam member having at least one recess adjacent to the eccentric portion of said cam member constructed on said neck portion in the vicinity of said shoulder and the lower end of said neck threads; said cap having an inner cup means for sealing said container, including a top integral with a continuous depending sidewall means, one portion of said depending sidewall means having threads formed thereon adapted to mate with the neck threads of said container, at least one downwardly projecting lug formed on another portion of said depending sidewall means adapted to contact said cam member when said threaded portion of said cap is adjacent to its sealing position on said neck, and a lower portion of said depending sidewall means extending sufficiently below said cam member and laterally spaced from said neck portion to permit said projecting lug portion to clear said recess of said cam member for disengagement of said safety cap from said container; and an over cup member, larger in diameter than the span of a child's hand so that a child is unable to open said safety cap, substantially surrounding said inner cup means having a top and integral side; said over cup member connected to said inner cup means, so that when a force is exerted against said over cup member to said inner cup means at predetermined positions, said inner cup means and said over cup member are transversely deformed to disengage said projecting lug portion from said recess of said cam member.

Claim 3

The safety cap forming a closure member for a container of claim 1 wherein said inner cup means for sealing said container comprises a pair of concentric cup members, wherein: said pair of cup members is constructed and arranged so that a closure cup has a top integral with a continuous depending sidewall, said depending sidewall having threads formed on the inner surface of said sidewall adapted to mate with neck threads of said container, and a middle cup member having a top formed to said closure cup, said middle member having a depending sidewall with at least one downwardly projecting lug portion formed on said sidewall adapted to contact said recess of said cam member when said closure cup is adjacent to its sealing position on said neck, the lower portion of the sidewall of said middle member extending sufficiently below said cam member and laterally spaced from said neck portion to permit transverse deformation of the sidewall of said depending member to permit said projecting lug portion to clear said recess of said cam member for disengagement of said safety cap from said container.

Claim 4

A safety cap forming a closure member for a container of claim 1 wherein said inner cup means comprises a single inner cup with threads on one portion of said sidewall and said lug on another portion of said sidewall.

Claim 5

A safety cap forming a closure member for a container of claim 1 wherein said over cup includes supplemental means for transferring force exerted to said over cup member to said inner cup means, said supplemental means connected at least on one end to the inner surface of said over cup, wherein said supplemental means may also serve as reinforcement to said over cup member to resist permanent deformation and fatigue failure due to repetitious squeezing of said over cup means.

Claim 6

A safety cap forming a closure member for a container of claim 1 wherein said over cup member includes a supplemental means for transferring force exerted against said over cup member to said inner cup means, said supplemental means connected at least on one end to the outer surface of said inner cup means whereby said supplemental means may also assist said inner cup means to resist permanent deformation and fatigue failure due to repetitious squeezing of said over cup member.

Claim 7

A safety cap forming a closure member for a container of claim 1 including means for draining said over cup member so that said over cup member cannot be used as a drinking cup when said safety cap is removed as a closure for the container.

Claim 8

A safety cap forming a closure member for a container of claim 1 wherein said inner cup means has a depending integral plug means constructed and arranged to mate with the neck of said container so that said neck portion is reinforced by said plug means.

Claim 9

A child-proof over a cap for container having a cylindrical body, with an integral bottom and an open upper end, complementary thread means on said upper open end of said container, and a locking element connected to said container in the vicinity of said container's upper open end, said child-proof cap comprising: a first inverted cup-shaped cover for closing said upper open end of said container; thread means on said first inverted cover for screwing said first inverted cup-shaped cover onto said complementary thread means on said upper open end of said container; a second inverted cup-shaped cover, larger in diameter than said first inverted cover, wherein said second inverted cover is connected to said first inverted cover; a complementary locking element on said second inverted cup-shaped cover so as to engage said locking element in the vicinity of said upper open end of said container; whereby when said second inverted cover is squeezed at predetermined places said complementary locking element of said second inverted cover and the locking element of said upper open end are disengaged so that said first inverted cover is unscrewable from said upper end; a third inverted cup-shaped cover connected to said second inverted cover so that said complementary locking element of said second inverted cover and the locking element of said upper open end are disengagable only when said third cover is squeezed by an adult-sized hand at predetermined locations on said third inverted cover; auxiliary means for directing the squeeze of said adult-sized hand applied to said third inverted cover to said second inverted cover at predetermined places, resulting in said complementary locking element of said second inverted cover to disengage the locking element of said container so that said first inverted cover is unscrewable from said upper open end; and means for draining said third inverted cover so that said third cup means is unusable as a drinking cup when not used as a cap for said container.

Claim 10

A child-proof over a cap for container having a cylindrical body, with an integral bottom and an open upper end, complementary thread means on said upper open end of said container, and a locking element connected to said container in the vicinity of said container's upper open end, said child-proof cap comprising: a first inverted cup-shaped cover for closing said upper open end of said container; thread means on said first inverted cover for screwing said first inverted cup-shaped cover onto said complementary thread means on said upper open end of said container; a second inverted cup-shaped cover, larger in diameter than said first inverted cover, wherein said second inverted cover is connected to said first inverted cover; a complementary locking element on said second inverted cup-shaped cover so as to engage said locking element in the vicinity of said upper open end of said container; whereby when said second inverted cover is squeezed at predetermined places said complementary locking element of said second inverted cover and the locking element of said upper open end are disengaged so that said first inverted cover is unscrewable from said upper end; a third inverted cup-shaped cover connected to said second inverted cover so that said complementary locking element of said second inverted cover and the locking element of said upper open end are disengagable only when said third cover is squeezed by an adult-sized hand at predetermined locations on said third inverted cover; auxiliary means for directing the squeeze of said adult-sized hand applied to said third inverted cover to said second inverted cover at predetermined places, resulting in said complementary locking element of said second inverted cover to disengage the locking element of said container so that said first inverted cover is unscrewable from said upper open end; and means for draining said third inverted cover so that said third cup means is unusable as a drinking cup when not used as a cap for said container.
