One-piece self-leveling measured dose dispensing closure

摘要

A single dose dispensing closure has a main body with an upper skirt portion for measuring and dispensing a predetermined dose of a flowable product from a container. A bottom wall, a rearwardly angled wall extending upwardly from the bottom wall, and an interior surface of the upper skirt together define a measuring reservoir. A port allows a product to flow from a container into the main body. A lid is movable to a closed position in which the lid portion and the main body define a filling chamber. A hinged closure tab seals an exit orifice on the front of the lid portion. When the exit orifice is closed, a user inverts the dispensing closure and container to substantially fill the filling chamber. When the dispensing closure is righted, a predetermined dose of the flowable product is retained in the reservoir, ready to be dispensed through the exit orifice.

主权项

1. A single dose dispensing closure for dispensing a flowable product from a product container, said single dose dispensing closure comprising:
a main body portion having a middle deck, a lower skirt portion extending downwardly from the middle deck and an upper skirt portion extending upwardly from the middle deck, said lower skirt portion being configured and arranged to be secure to a product container; said main body portion having a front and a rear, said middle deck having a port for passage of said flowable product from said container into said main body portion, said port being located adjacent the rear of said main body portion, said main body portion further including an interior wall extending upwardly from said middle deck, said interior wall being integrally connected with an interior surface of the upper skirt portion whereby said middle deck, said interior wall and said upper skirt portion cooperate to define an interior measuring reservoir for measuring a predetermined dose of said flowable product; a lid portion connected to said upper skirt portion of said main body portion by a living hinge, said lid portion being movable from an open position to a closed position, said main body portion and said lid portion cooperating to define a filling chamber when said lid portion is in said closed position, an exit orifice defined on said lid portion and positioned so that it is adjacent the front of said main body portion when said lid portion is in said closed position; and an exit orifice closure tab; whereby said flowable product enters said filling chamber through said port when said exit orifice is closed by said closure tab and said product container is inverted, and further whereby said flowable product drains back into said product container through said port when said product container is uprighted, leaving said predetermined dose of flowable product within said reservoir, and still further whereby said predetermined dose of flowable product passes from said reservoir through said exit orifice when said exit orifice is opened and said product container is inverted again.
