Abstract
Abstract This disclosure relates to a child-proof, tamper indicating closure having as a conventional component thereof a ''''U-PRESSIT'''' cap formed with an end panel and a peripheral skirt terminating in a locking curl with the peripheral skirt being movable between generally frusto-conical unlocked and generally cylindrical locked positions in a conventional manner, the improvement comprising means for moving the peripheral skirt between the unlocked and locked positions carried by an annular wall in external telescopic relationship to the peripheral skirt, the annular wall further having means for confiningly housing the inner cap in its unlocked position and further including means for retaining the peripheral skirt in the locked position after having been moved thereto by said moving means. The annular wall further includes a panel frangibly connected thereto in overlying relationship to the inner cap end panel to indicate tampering should the frangible connections be fractured.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
A closure comprising an inner-cap defined by an end panel and depending peripheral skirt terminating in means for releasable clamping securement to a container, said peripheral skirt being deflectable between an unlocked position at which the peripheral skirt is of a generally frusto-conical condition enlarging in a direction away from said end panel and a locked position at which the diameter of the peripheral skirt is lessened as compared to its maximum in said frusto-conical condition, means for moving said peripheral skirt from said unlocked to said locked position, said moving means being carried by a annular wall in external telescopic relationship to said peripheral skirt, said annular wall having confining means for entirely confiningly housing said inner-can within the axial length of said annular wall in said unlocked position, said confining means also constituting means for contact with said inner cap to aid positively in the urging of said inner-cap into said unlocked position during the raising of said cap from said container, and said annular wall further including means for retaining said peripheral skirt in said locked position after having been moved thereto by said moving means.
Claim 2
Dependent Claim
189 words
A closure comprising an inner-cap defined by an end panel and depending peripheral skirt terminating in means for releasable clamping securement to a container, said peripheral skirt being deflectable between an unlocked position at which the peripheral skirt is of a generally frusto-conical condition enlarging in a direction away from said end panel and a locked position at which the diameter of the peripheral skirt is lessened as compared to its maximum in said frusto-conical condition, means for moving said peripheral skirt from said unlocked to said locked position, said moving means being carried by a annular wall in external telescopic relationship to said peripheral skirt, said annular wall having confining means for entirely confiningly housing said inner-can within the axial length of said annular wall in said unlocked position, said confining means also constituting means for contact with said inner cap to aid positively in the urging of said inner-cap into said unlocked position during the raising of said cap from said container, and said annular wall further including means for retaining said peripheral skirt in said locked position after having been moved thereto by said moving means.
Claim 3
Dependent Claim
