Abstract
Abstract A dispensing closure for attachment to the finish of a bottle and a package which includes a bottle and such a dispensing closure attached to the finish thereof. The closure includes a molded plastic body portion with an irregular, generally horizontal top structure and a dispensing opening in such top structure, a pivotable member which is frictionally and pivotally attached to the top structure and which is pivotable in a vertical plane between a generally horizontal, closing position and an upright, open or dispensing position in which a dispensing passage in the pivotable member is aligned with the dispensing opening in the body portion. The closure also includes a dispensing control member which is rotatable in a horizontal plane with respect to the body portion, the dispensing control member having a horizontal disc with a slot therein, the disc being capable of rotation to bring the slot into alignment with the pivotable member to permit the pivotable member to be pivoted through the slot from the closing position to the open or dispensing portion.
