Abstract
A closure having a stopping mechanism whereby a stop lug is positionable between a flexed and unflexed position relative to a spring gap. The stop lug may project from a skirt of the closure top wall. The spring gap is positioned adjacent the stop lug to provide an area for the stop lug to travel when outside forces are applied to the stop lug and subsequently return back to the unflexed position. The stop lug may have a substantially vertical support rib in combination with a plurality of annularly spaced ribs.
Claims26
A closure comprising:
- a closure body having a top wall with a downwardly depending skirt at a first radius, said depending skirt having an outer annular surface and an inner annular surface on opposing sides of said depending skirt;
- at least one thread projecting inwardly from said inner annular surface of said depending skirt;
- a non-child resistant stop lug projecting from said depending skirt;
- and
- a rib extending substantially vertically along said outer annular surface of said depending skirt and connected to said stop lug, wherein said rib is positioned to provide a supporting engagement with said stop lug and an unscrewing engagement with outside forces applied to said closure body.
A double shell closure comprising:
- a closure body including a top wall with a downwardly depending outer skirt and inner skirt, said inner skirt having an inner surface facing inward toward the center of said closure body and an outer surface facing outward away from the center of said closure body;
- at least one thread inwardly projecting from said inner surface of said inner skirt;
- at least one stop lug outwardly projecting from said inner skirt;
- and
- a support rib extending from adjacent said stop lug upwardly towards said top wall along said outer surface of said inner skirt, wherein said support rib is one of a plurality of unscrewing ribs positioned annularly about said inner skirt.
A closure comprising:
- a closure body having top wall with a depending outer skirt and inner skirt, wherein said inner skirt having an outer surface and an inner surface;
- at least one thread projecting from said inner surface of said inner skirt;
- a plurality of unscrewing lugs projecting from said outer surface of said inner skirt and annularly positioned about said inner skirt;
- a stop lug projecting from a distal end of said inner skirt spaced from said top wall;
- and
- at least one of said plurality of unscrewing lugs being a support rib positioned adjacent said stop lug.
