A valve assembly includes a valve housing defining a metering chamber and an elongated stem. The stem is axially movable with respect to the valve housing for dispensing liquid and is rotatable for adjusting the length of the stroke of a piston to thereby select the volume of liquid dispensed with each actuation of the stem. A sliding float member is fitted around the stem within the chamber and is axially slidable with respect to the stem but is locked for rotation with the stem. The lower surface of the sliding float abuts, and floats above the upper surface of the piston, and the lower end of the stem is rotatable within the piston. A spring extends between a prong on the stem and the sliding float for urging the stem axially outward of the container and for urging the piston in a direction which maximizes the volume of the metering chamber such that the spring rotates with the stem and the stem rotates free of the piston.

A non-resealable, snap-fitted closure comprises a closure, a drop ring and a container. The closure has a sleeve with a sleeve snap. The drop ring has an internal snap and an external snap wherein the internal snap engages the sleeve snap of the closure when the closure engages the drop ring. The container has a neck and a neck snap, wherein the neck snap and the internal snap of the drop ring engage when the closure and the drop ring engage the neck. The neck snap of the neck and the internal snap of the drop ring are an order of magnitude stronger than the sleeve snap of the sleeve and the external snap of the drop ring. When the closure is removed from the neck, the drop ring remains attached to the neck and is free to move vertically up and down along the neck, thereby preventing reattachment of the closure to the container.

A child resistant attachment for containers used for storing and dispensing potentially dangerous materials, such as medicament tablets or the like, the attachment being resistant to opening by children but readily openable by adults, particularly adults having impaired manual dexterity of their hands and/or fingers. In a particularly preferred embodiment, the attachment comprises a finish portion including thread ring with an integrally molded annular tab ring or collar generally concentric to the thread ring and a closure which is releasably secured to the thread ring by means of complementary screw threads. The tab ring or collar preferably includes a pair of resiliently deformable spring-like pushtabs containing vertical extensions which engage interlocking pawls on the innermost surface of the closure skirt when the closure is fully assembled onto the finish portion. To remove the closure, the opposed pushtabs must be depressed prior to applying unscrewing torque to the closure to disengage the pushtab extensions from the interlocking pawls on the closure. In a particularly preferred embodiment, the finish portion of the child resistant attachment of the present invention is integrally molded with the container in a ready to use configuration without the need for additional assembly or molding operations. Methods for producing the child resistant attachment and child resistant packages employing it are also disclosed.

A tamper evidency system for a container having a closed body, an open ended finish portion, and a closure to close the open end of the finish portion. The closure has a top and a depending wall portion which has cam teeth extending inward toward the finish portion. A lug extends from the outer surface of the finish portion, located between the finish portion and the cam teeth when the closure installed. The lug is integrally molded to the finish portion by a shearable web. The shearable web has an orientation, which enables the lug to be rotated about the shearable web by the cam teeth without interfering with installation when the closure is installed onto the finish portion. The lug also engages one of the cam teeth when the closure is removed from the finish portion. The lug prevents the closure from being removed without first shearing the lug from the finish portion at the shearable web. The lug is unreachable for manipulation without the use of tools. In addition, the lug has a corner which contacts the outer surface of the finish portion when one of the cam teeth rotates the lug in a closure removal direction. The lug pivots about the corner upon contact with the finish portion to create a mechanical advantage for shearing the lug from the finish portion at the shearable web. The tamper evidency system may further comprise a flag extending from the lug outside the open end of the closure in order to be visible to a consumer before the lug has been sheared off. Alternatively a lug and shearable web are integrally molded with a closure, and engaging cam teeth are formed on a container finish.

A method for stripping an open ended bellows part from an injection mold has as a first step the injection molding of a bellows part. The bellows part has a resilient portion located between a core pin and a first split cavity and a substantially rigid portion located between the core pin and a second cavity. The substantially rigid portion has a first open end and an external undercut portion, and the resilient portion of the bellows part has an inner surface and a second open end. The first split cavity opens laterally to permit the resilient portion of the bellows part to be stripped from the core pin. Compressed gas passes through the core pin to the inner surface of the resilient portion of the bellows part while both open ends of the bellows part are closed off by the second cavity and the core pin. As the cavity and core portions of the mold separate, the second cavity grips the undercut portion of the substantially rigid portion of the bellows part, thereby pulling the resilient portion of the bellows from the core pin while compressed gas maintains the resilient portion expanded. Finally, the second cavity either opens or has a stripper rod to disengage the undercut portion of the substantially rigid portion of the bellows part so that the bellows part may be ejected from the injection mold.
