摘要： A ratcheting fastener system such as for point of purchase displays. A bolt has a shank with a head end and a distal end, and a plurality of bolt threads on the shank, each thread having a thread start at the distal end. A nut has a bore with a plurality of thread segments in the bore adapted for engaging the bolt threads when axial force is applied to the bolt with the distal end inserted in the nut. Deflection of the nut thread segments occurs in controlled locations. The bolt and nut can be formed as a single unit connected by a frangible link.

摘要： This relates to a closure cap having an end panel which is equipped with a central button or panel area so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area has been found and such additional stored energy is obtained by utilizing faceted areas or portions.
