ABSTRACT:
A dispenser valve for use in combination with a plastic dispensing bottle or container wherein the container has an elongate tubular shaped neck with an interior retention bead projecting radially inward from the surface. The mouth is relatively large to allow quick filling of the container. The valve is a push pull type valve including a central tubular member with a head attached to a dispensing end thereof and a vaned tail section attached to an opposite end. The tubular section has an inlet in the middle thereof communicating with a central passageway and the dispensing aperture. The vane section is sized somewhat larger than the width of the retaining bead or neck so as to inhibit removal of the valve from the neck. The valve preferably includes a pair of annular fins surrounding the tubular member with one of the fins extending between the tubular member and the neck so as to both support and seal therebetween. Alternative embodiments of the present invention include various locking mechanisms to prevent the valve from inadvertently being placed in an open position during transit. The valve preferably also includes an integrally molded closure for plugging the dispensing aperture thereof.
