Abstract

A one-piece child-resistant dispensing closure for a container which has an open end. The closure has a skirt which mates with the end of the container and a top which spans the space defined by the skirt. Preferably there are two dispensing openings through the top, each of which is surrounded by an upwardly extending rim. The closure also comprises a lid for each opening and a hinge for each lid. The hinges and lids are integral parts of the closure. The lids have similar rims which fit around the rims on the closure top when the lids are swung over to close the dispensing openings. In the closed position, ribs on the edges of the pairs of opposed rims snap over each other and ears on the inner sides of the lids are closely spaced from a fulcrum on the closure top. The engagement of the ribs holds the lids closed. Pry means, such as a coin or blade, may be inserted between the fulcrum and a lid ear to pry the particular lid open.

Claims2

Dependent claims

A one-piece, child-resistant, dispensing closure for a container having an open, circular upper end, said closure being formed of a stiffly resilient material and comprising,

(a) a skirt adapted to telescopingly mate with the open end of said container,
(b) a disk-like top integral with said skirt and extending across the space defined by said skirt, said top having two dispensing openings therethrough,
(c) an upwardly extending, integral top rim on said top surrounding each of the dispensing openings therein,
(d) a lid for each of said openings,
(e) a hinge for each of said lids that is integral with said top and with the respective one of said lids, said hinges extending outwardly from opposite sides of said top,
(f) an integral lid rim on each of said lids that is adapted to mate with the associated one of said top rims when said lid is swung over into closed position overlying the respective one of said openings,
(g) overlapping ribs on said top rims and said lid rims which are interengaged when said lids are in closed position,
(h) means for retaining said closure in place on the end of said container, and
(i) cooperating means consisting of a fulcrum at the center of the top and an ear on the inner side of each of the lids which extends inwardly to closely spaced adjacency to said fulcrum when said lid is in closed position thereby providing a space into which pry-means may be inserted for disengaging the ribs and moving said lid away from closed position.
