Abstract
A child resistant flip-top closure. The base of the closure is provided with an upwardly projecting rib which lies alongside the lid or movable element of the closure when the lid is in the closed position. The rib impedes access to the lid and hence opening of the closure. The rib includes a resilient portion which can be manually engaged and flexed outwardly, away from the lid to provide access to the lid. The resilient portion of the rib may be curved inwardly along its top edge.
Claims22
A closure comprising:
- (a) a base having a top surface facing generally in an upward direction and an opening in said top surface;
- (b) a lid;
- (c) means for mounting said lid to said closure for movement between a closed position wherein said lid overlies said top surface and occludes said opening and an open position wherein said lid does not occlude said opening, so that said lid moves upwardly away from said top surface in movement from said closed position toward said open position;
- (d) an elongated, curvilinear rib protruding upwardly from said base and extending at least partially around said opening, said rib having an inward face facing toward said opening and an outward face facing away from said opening, said rib being disposed alongside said lid with said inward face facing toward said lid so that said rib impedes access to said lid when said lid is in said closed position, said rib including a resilient portion and two substantially rigid portions continuous with said resilient portion and extending from opposite ends thereof;
- and
- (e) means for permitting manual engagement of said resilient portion of said rib to thereby permit outward flexure of said resilient portion away from said lid so as to expose said lid for manual engagement.
A device having a fixed element, a movable portion juxtaposed with said fixed element when said movable element is in one position thereof, and a rib projecting in an upward direction from said fixed element so that said rib is disposed alongside said movable element and impedes access thereto when said movable element is in said one position, said rib having an inward face facing towards said movable element and an outward face facing away from said movable element, said rib including a resilient portion, an upper edge of said resilient portion of said rib remote from said fixed element being arcuate and convex in the inward direction.
