Two-piece child-resistant dispensing closure

摘要

A child resistant dispensing closure for dispensing a product from a container has a cap base and a cap that can be secured to a container. The cap base has a locking tab that engages a locking lug on a container, to prevent removal of the cap base from the container. To seal a pour spout on the cap base, a cap is removably secured to the cap base. A child resistant mechanism prevents accidental removal of the cap from the cap base. The child resistant mechanism may include a child resistant stop tab on the cap that selectively engages a child resistant stop lug located on either the container or the cap base. Alternatively, the child resistant mechanism may include a latch hook on the cap base that selectively engages a stepped locking shoulder on the cap skirt.

1. A child resistant dispensing closure for dispensing a product from a container, said container including a shoulder, an outwardly threaded neck extending upwardly from said shoulder, at least one locking lug on said shoulder adjacent to said neck, and at least one child resistant stop lug on said shoulder adjacent to said neck, said at least one locking lug extending above said at least on child resistant stop lug, said child resistant stop lug extending radially further away from said neck than said locking lug, said dispensing closure comprising:
a cap base including
a deck,an outer base skirt depending from said deck, said outer base skirt having an inwardly threaded inner surface for engaging said outwardly threaded dispensing neck on said container, said outer base skirt further having an outwardly threaded outer surface,at least one locking tab extending from said outer base skirt, said locking tab engaging said locking lug on said container to align said cap base on said container when said cap base is threadably engaged on said container neck and to prevent removal of said cap base from said container when said cap base is threadably engaged on said container neck, said outer base skirt remaining above said child resistant stop lug when threadably engaged on said container,a pour spout extending upwardly from said deck, said pour spout having a front and a rear and a dispensing passage therein, said pour spout having a pour lip formed at a front terminal edge thereof,an annular drain back channel encircling said pour spout and depending downwardly from said deck within said lower skirt, said drain back channel having a bottom wall sloping downwardly towards a rear terminal edge of said pour spout,a drain back opening formed in said drain back channel so that a product may drain from said channel back into said container; and a cap including
an upper wall,an outer cap skirt depending downwardly and outwardly from said upper wall and below said outer base skirt, said cap skirt having an inwardly threaded inner surface for engaging said outwardly threaded lower skirt on said cap base,an inner annular sealing wall depending downwardly from said upper wall, said annular sealing wall being configured to sealingly engage an outer wall of said drain back channel in said cap base, anda child resistant stop tab extending inwardly from said inner surface of said outer cap skirt, said child resistant stop tab being engageable with said child resistant stop lug on said container when said cap is threadably engaged with said cap base to prevent inadvertent removal of said cap from said cap base unless a radial inward pressure is applied to the outer cap skirt at opposing positions spaced from the child resistant stop tab to deform the outer cap skirt outwardly so that the child resistant stop tab clears the child resistant stop lug.
