Abstract
Abstract So-called ''''press-top'''' child-resistant closures have been constructed utilizing a bowed top and a peripheral skirt including holding means arranged so that upon pressure being applied to the center of the top, the skirt will expand so as to be capable of passing over a retaining structure on a bottle neck engaged with the holding means on the skirt. Inadvertent opening of these closures during the stacking can be prevented by using with them a ring of material extending around the skirt and serving to prevent expansion of the skirt upon pressure being applied to the center of the top. Preferably the ring of material is in the form of a tear-off strip which indicates whether or not a container has previously been opened.

In a closure having a top and an integral peripheral skirt, said skirt including holding means spaced from said top, said closure being adapted to be used over the end of a container neck with said top covering the end of said neck and said skirt fitting around said neck so that said holding means engages cooperating means on the exterior of said neck to prevent removal from said Closure from said neck, said top being capable of being pressed at its center towards said neck in order to cause flexure in said closure resulting in expansion of said skirt and in said holding means being released from said cooperating means so that said closure can be removed from said neck, the improvement which comprises: a ring of material extending around the periphery of said skirt, said ring of material serving to prevent expansion of said skirt upon pressure being applied to the center of said top in order to prevent said holding means from being released from said cooperating means, said ring of material is integral with said skirt and extends beneath said skirt away from said top, said ring of material includes a second holding means designed to engage other cooperating means on the exterior of said neck so as to securely hold said closure against removal from said neck prior to said ring being severed from said neck, said ring of material comprises a strip of material extending around the periphery of said strip and joined to said skirt, said strip having adjacent ends adjacent to said strip, said ends being joined together and said strip being joined to said skirt by easily severed thin lines of material, said ring of material being capable of being removed from said skirt so as to permit expansion of said skirt when said top is pressed at its center towards said neck so that after removal of said ring said closure can be removed from said neck.
