A dispensing closure for attachment to the finish of a bottle to selectively permit or prevent the dispensing of a flowable product in the bottle through an opening in the closure. The closure is made up of a molded plastic, cup-shaped base cap member, the dispensing opening being in a top of such base cap member, and a molded plastic generally planar closing member an end of which is pivotally received in a depressed socket portion of the base cap member. The closing member carries a plug which is engaged in the dispensing opening of the base cap member when the closing member is in a first position relative to the base cap member, and the plug is out of engagement with the dispensing opening when the closing member has been pivoted with respect to the base cap member from the first position to a second position. The end of the closing member which is received in the depressed socket portion of the base cap member is reinforced to prevent it from popping out of the depressed socket portion as the closing member is pivoted from the second position back to the first position.

A dispensing closure for a bottle that contains a flowable product, the bottle having an annular closure receiving finish, said closure comprising; a cup-shaped base cap member having an annular skirt with bottle finish engaging means, said annular skirt being adapted to surround and engage the finish of the bottle, said base cap member further having an interrupted generally planar top positioned within an annulus defined by said annular skirt, a recessed wall portion in an interruption in said generally planar top, said recessed wall portion extending inwardly from an edge of said top past a center thereof to an end, said recessed wall portion having a depressed socket portion at said end thereof and a dispensing opening which is away from said depressed socket portion and which extends through said base cap member, whereby the flowable product can be dispensed from the bottle through said dispensing opening; and a closing member having a generally planar portion with a first end, a second end, and a flange extending generally normally to said generally planar portion from one of said first end and said second end, said flange having a free edge, said closing member further having spaced apart first and second side surfaces extending normally from said flange partly toward the other of said first end and said second end and a plug which extends from said generally planar portion and which is spaced between said first end and said second end, said one of said first end and said second end of said closing member being received in said depressed socket portion of said base cap member, said closing member being pivotable with respect to said base cap member about a pivot axis between a first position in which said closing member is engaged in said recessed wall portion of said base cap member with said plug being received in said dispensing opening in said base cap member to prevent the flowable product from being dispensed through said dispensing opening and a second position in which said closing member extends away from said base cap member and said plug is away from said dispensing opening to permit the flowable product in the bottle be dispensed through said dispensing opening; one of said base cap member and said closing member being provided with projection means, the other of said base cap member and said closing member being provided with recess means, said recess means frictionally engaging said projection means along said pivot axis, said pivot axis extending through said projection means and said recess means; said flange of said closing member further having thickened portion means extending from said generally planar portion partly to said free end, and further extending from at least one of said first surface and said second surface, said thickened portion means stiffening said one of said first end and said second end of said closing member to prevent said closing member from being disengaged from said base cap member as said closing member is being pivoted about said pivot axis from said second portion to said first position.
