Abstract

Abstract A child-proof container comprises a tubularly-shaped main housing formed of a resilient plastic having first and second end edges. A permanent bottom wall is integrally formed with the main housing adjacent the first end edge of the main housing but spaced slightly inwardly from the first end edge. A cover is hingedly attached at the opposite end of the main housing also spaced slightly inwardly from the second end edge of the main housing. An internal surface of the main housing includes a slot for receiving a free edge of the cover when the cover is in a closed position, the slot being also located slightly inwardly from the second end edge, and a "stop" located inwardly from the slot for engaging an inner surface of the cover to prevent further inward rotation of the cover. In one embodiment, the tubularly-shaped main housing has a circular cross section and in a second embodiment, it has a partially circular and partially flat shape. An embellishment of either of these embodiments includes a false or fake cover at the closed end of the main housing.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 280 words
A container defining an opening, said container including an integral cover for covering said opening, and being difficult for children to both recognize and open, said container comprising: a tubularly-shaped main housing formed of a resilient material having internal and external surfaces and first and second end edges; a bottom wall integrally formed with said tubularly-shaped main housing adjacent said first end edge of said main housing, said bottom wall permanently closing a first end of said tubularly-shaped main housing by being integrally attached to said housing about the bottom wall's perimeter; a cover integrally formed with said tubularly-shaped main housing adjacent said second end edge of said main housing, said cover being integrally attached to said tubularly-shaped main housing adjacent said second end edge thereof, but inwardly spaced from said second end edge, said attachment being along a portion only of the outer perimeter of said cover so as to form a hinge means inwardly spaced from said second end edge for allowing said cover to be selectively rotated between a closed position closing a second end of said main housing and an open position rotated outwardly from said main housing; said internal surface of said tubularly-shaped main housing including a slot for receiving a free edge of said cover when said cover is in a closed position, said slot forming a shoulder located inwardly from said second end edge, for engaging an inner surface of said cover to prevent further inward rotation of said cover from said closed position such that an outer surface of said cover is spaced inwardly from said second end edge of said tubular main housing when said cover is in said closed position.
Claim 2
Dependent Claim 280 words
A container defining an opening, said container including an integral cover for covering said opening, and being difficult for children to both recognize and open, said container comprising: a tubularly-shaped main housing formed of a resilient material having internal and external surfaces and first and second end edges; a bottom wall integrally formed with said tubularly-shaped main housing adjacent said first end edge of said main housing, said bottom wall permanently closing a first end of said tubularly-shaped main housing by being integrally attached to said housing about the bottom wall's perimeter; a cover integrally formed with said tubularly-shaped main housing adjacent said second end edge of said main housing, said cover being integrally attached to said tubularly-shaped main housing adjacent said second end edge thereof, but inwardly spaced from said second end edge, said attachment being along a portion only of the outer perimeter of said cover so as to form a hinge means inwardly spaced from said second end edge for allowing said cover to be selectively rotated between a closed position closing a second end of said main housing and an open position rotated outwardly from said main housing; said internal surface of said tubularly-shaped main housing including a slot for receiving a free edge of said cover when said cover is in a closed position, said slot forming a shoulder located inwardly from said second end edge, for engaging an inner surface of said cover to prevent further inward rotation of said cover from said closed position such that an outer surface of said cover is spaced inwardly from said second end edge of said tubular main housing when said cover is in said closed position.
Claim 3
Dependent Claim 17 words
A container as claimed in claim 1 wherein said tubularly-shaped main housing has a circular cross section.
Claim 4
Dependent Claim 35 words
A container as claimed in claim 2 wherein said bottom wall is spaced inwardly from said first end edge in approximately the same manner as said cover is spaced inwardly from said second end edge.
Claim 5
Dependent Claim 27 words
A container as claimed in claim 2 wherein said tubularly-shaped main housing has an external surface at its first end having the appearance of a conventional cover.
Claim 6
Dependent Claim 22 words
A container as claimed in claim 1 wherein said tubularly-shaped main housing has a partially circular cross section with one straight side.
Claim 7
Dependent Claim 32 words
A container as in claim 5 wherein said bottom wall is spaced inwardly from said first end edge in approximately the same manner as said cover is spaced from said second edge.
Claim 8
Dependent Claim 26 words
A container as in claim 1 wherein said tubularly-shaped main housing has an external surface at its first end having the appearance of a conventional cover.
