Abstract:
A dispensing closure for a foil covered container comprising:a base, said base supporting a spout and diaphragm, said spout being coupled to said diaphragm and pivotally mounted to said base for pivotal movement between an open position oriented upright on the upperside of said base and a closed position oriented alongside said upperside of said base;said base including an upper side and an underside;said spout extending through said base, said spout including a dispensing end, and an entry end and a passage between said ends extending through said base from said upperside to said underside of said base;a barrier supported on said underside of said base;said barrier for closing said entry end of said spout passage when said spout is in said closed position to close said passage and prevent fluid passage through said spout;a frictional latch for retaining said spout in said closed position, said frictional latch located at an outer end of said spout;said base including a recess for receiving said spout when said spout is in said closed position to prevent said spout from being gripped from the side, said recess being bounded at least in part by said diaphragm;a frangible strip extending upwardly from a side of said base in front of an open end to said recess, said frangible strip being adjacent to and confronting said dispensing end of said spout to block access to said dispensing end when said spout is in the closed position, said frangible strip being detachable from said base to permit access to said dispensing end for pivoting said spout to the open position;foil piercing means, said foil piercing means being mounted for pivotal movement with said spout, wherein pivotal movement of said spout from said closed position to said open position, concurrently pivots said piercing means from a position alongside said underside surface of said base to a down standing position, extending away from said base;said foil piercing means including:a first and second elongate knife members, said first and second members mounted in spaced relation to each side of said entry end of said spout and extending in parallel, said elongate knife member each containing a pointed end and being of a length greater than the height of said base, whereby said knife members may contact and pierce said foil covering as said knife members are pivoted by said spout to said down standing position; andsaid base, spout, diaphragm, barrier, frangible strip, latch, and foil piercing means being formed as a unitary one-piece assembly.
