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.
Claims31
A closure comprising:
- a closure body having a top wall with a projecting skirt;
- said skirt having a rotational stop lug and a spring gap, wherein said stop lug projects from said skirt and adjacent to said spring gap, wherein said stop lug annularly pivots between a flexed position into said spring gap and an unflexed position out of said spring gap;
- and
- said spring gap being substantially open when said stop lug is in said unflexed position and said spring gap being substantially closed when said stop lug is in said flexed position.
A closure comprising:
- a top wall with a downwardly depending skirt;
- at least one thread projecting from said depending skirt;
- a rotational stop lug extending outward from said depending skirt and adjacent a spring gap formed in said depending skirt;
- said spring gap being a recess extending from a distal end of said skirt upwardly towards said top wall;
- and
- said stop lug being substantially resilient to annularly flex into and out of a portion of said spring gap.
A closure comprising:
- 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 and an outer surface facing outward away from the center of said closure;
- a rotational stop lug extending outward from said inner skirt;
- a spring gap adjacent said stop lug permitting annular deformation of said stop lug into a portion of said spring gap;
- and
- a rib depending from said top wall and extending substantially vertical along said outer surface of said depending inner skirt and said stop lug.
