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.
