An injection molding tool having a collapsible core which is movably mounted with respect to a mold plate. The mold plate is movably mounted with respect to a stripper plate that can be used to eject or remove the molded part from the injection molding tool. A retainer is fixedly positioned with respect to the mold plate so that it contacts at least a portion of a molded part when in a mold position. The retainer can be a sleeve with a through opening within or through which the collapsible core is mounted.

A carrier ring assembly is provided for use with a closure for a container. The carrier ring assembly includes a carrier ring and a valve. The carrier ring includes a retention bead and a retention space. The valve is located at least partially within the carrier ring and has a retention portion positioned within the retention space.

Valve carrier ring assembly

A positive orientation container and closure combination is provided. The container includes at least one flange segment having a front and a back face. The container further includes a gap defined by the front face of one of the flange segments and the back face of one of the flange segments. The closure includes a plurality of collar segments. The closure includes at least one collar segment having an engagement face to establish a positive orientation of the closure at a predetermined position.

Closure system with orientation and removal capability

There is disclosed a closure comprised of a valve, a base unit and an upper unit. The base unit has a base surface with a peripheral skirt. The base surface has an aperture with a cylindrical section extending above and below the base surface. The cylindrical section has an aperture therethrough. The upper unit has an upper surface and an aperture adapted to align with the aperture of the cylindrical section of said base unit. The upper unit has a lid to cover the apertures in the base unit cylindrical section and the upper unit. A lid inner top surface has two projecting seals, one to maintain the valve closed when the lid is closed and the other to provide a seal when the lid is closed. and a latch mechanism attaches the base unit to the upper unit. A preferred latch mechanism comprises a projection and an interfitting recess, one being on the base section and the other on the upper section. The lid top surface preferably has an essential horizontal top surface. In a preferred embodiment the valve is a polymeric valve located in the aperture between the base unit and the upper unit and held in place by contact with both the base unit and the upper unit. The rheology of the product in the container and the characteristics of the valve are coordinated so that the product will be fully contained by the valve regardless of the orientation of the container, including being inverted.

A dispensing system includes a body having a base for extending from a container, and a support column projecting from the base. A discharge passage extends through the body and support column. A flexible, pressure-openable dispensing valve has a skirt mounted on the support column and has an outwardly extending, narrowing head defining a dispensing orifice at the distal end. A clamp member fits around the valve skirt and is engaged with the body to hold the body, valve, and clamp member together.

A closure is provided for an opening in a container having a wall around the opening and at least one thread on the wall. The closure includes (1) an attachment wall defining at least one thread for threadingly engaging the container wall thread, (2) an occlusion wall closing the attachment wall to occlude the container opening when the container is in the closed position, and (3) a continuously curving, peripheral, finger-engaging surface which defines (1) a plurality of circumferentially spaced protuberances, (2) a finger-receiving recess between adjacent protuberances, and (3) a finger-engaging rib projecting laterally from each of the protuberances.

Gripping structure of a closure

A dispensing system is provided to dispense a fluent product from a container that has an opening to the container interior. A support base is provided for supporting the container with the container opening oriented at least somewhat downwardly to accommodate gravity flow of the fluent material out of the container through the container opening. The support base has (1) a receiving aperture for receiving the container opening, (2) a discharge aperture, and (3) a flow path extending between the receiving aperture and the discharge aperture.

Inverted package dispensing system

In a dispensing system comprising a container having at least two storage chambers, each for a fluent material, the finishes of the respective chambers are arranged in a contiguous pair defining a cylindrical surface having outer threads, except for two anti-rotational flats. Each finish defines an outlet. A valve of a type that remains closed until opened by a differential between inside pressure and outside pressure overlies the outlet defined by each finish. A fitment defines a mixing chamber having two inlets, one for each storage chamber, and having an outlet. The fitment has two skirts, each having an inner surface having at least one rib, each defining an anti-rotational flat. The fitment fits over the paired finishes and over the valves so that the antirotational flats on the ribs engage the anti-rotational flats on the paired finishes. A collar having inner threads is threaded onto the paired finishes so as to hold the fitment, which holds the valves. Each valve has an elastomeric flange forming a seal between a margin of an associated outlet and a margin of an associated inlet. A dispensing spout is provided. The fitment and the dispensing spout have coacting formations, which permit the dispensing spout to be twisted in one rotational sense relative to the fitment so that the sealing formation of the dispensing spout engages the sealing formation of the fitment, to be twisted in the opposite sense relative to the fitment so that the sealing formation of the dispensing spout is disengaged from the sealing formation of the fitment, but not to become detached from the fitment.
