ONE-PIECE SQUEEZE-TO-DOSE DISPENSING CLOSURE

摘要

A dispensing closure for dispensing a flowable product from a container has a main body portion, a sealed lid portion, and a hinged closure tab held closed by a child-resistant latch. The main body is securable to a container by a lower skirt portion and includes an interior measuring reservoir. The dispensing closure receives a dip tube extending to the bottom of a container, and upon squeezing the container directs product from the dip tube through an entrance conduit into the dispensing closure. When pressure is released, product flows back into the container through the conduit leaving behind a measured dose within the measuring reservoir. A shroud depending from the lid portion prevents product from being squeezed directly from the entrance conduit out of the exit orifice. A child resistant actuator limits unintended opening of the hinged closure tab.

主权项

1. A dispensing closure for dispensing a flowable product from a product container, said 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 secured to a product container; said main body portion having a front and a rear; said middle deck including a dip tube receiver for receiving a dip tube that extends to the bottom of said product container, an entrance conduit formed at an edge of said dip tube receiver and extending upwardly from said bottom wall, said entrance conduit having an outer surface, said entrance conduit also having an opening defined at an upper end thereof, said middle deck, said outer surface of said entrance conduit, and an interior surface of said upper skirt portion cooperating to form an interior measuring reservoir for measuring a predetermined dose of said flowable product; said dip tube receiver and said entrance conduit together forming a path for fluid to pass from said dispensing tube into said interior measuring reservoir; a lid portion connected to said upper skirt portion of said main body portion, said lid portion being movable from an open position to a closed position; an exit orifice defined on said lid portion and positioned so that it is at the front of said main body portion when said lid portion is in said closed position; an exit orifice closure tab; a locking ledge protruding from a peripheral side edge of said closure tab; and a child-resistant latch formed on an outer lid skirt, said child-resistant latch having an upper latch tab portion and a lower actuator tab portion, said upper latch tab portion including a latch extending inwardly from said upper latch tab portion, said latch and said locking ledge being configured for interlocking engagement when said exit orifice is closed by said closure tab, said lower actuator tab portion being inwardly depressible to cause a corresponding outward displacement of said upper latch tab portion so that said latch disengages from said locking ledge allowing said closure tab be disengaged from said exit orifice; whereby said flowable product enters said dispensing closure from said product container through said entrance conduit when said flowable product is forced upwardly through said dip tube, and further whereby said flowable product in excess of said predetermined dose drains from said measuring reservoir through said entrance conduit when pressure is removed from said container, and said product passes from said measuring reservoir through said exit orifice when said exit orifice is opened and said product container is inverted.
