Abstract: A pump dispenser comprising a container having a neck (6) to which the pump is attached. A pump body (1) has an outward flange (91) through which it is supported on the edge of the container neck (6). A body/neck rotation stop mechanism (64,7) is provided by an interlock engagement between the pump body and the container neck, and has widely-spaced interlock projections (64) on the container neck (6), e.g. one or two projections, each having a circumferentially-directed abutment face (642). A series of spaced interlock teeth (71) projects down from the outward flange (91) of the pump body and these have respective abutment faces (711) to engage the neck projections and limit relative rotation of the pump body and neck. This can assure reliable action of a plunger-locking mechanism of the dispenser.

Abstract: A food and beverage reciprocating dispenser relies upon an external engine to shorten the axial travel and spring force required for actuation. This enables the delivery of more accurate and consistent dose volumes. The resulting pump has “bore ratios” that are improved by an order of magnitude in comparison to conventional designs.

Abstract: An all-plastic, reciprocating foam dispenser is contemplated. The dispenser relies upon a bellows that also serves as the air chamber/cylinder, thereby eliminating the need for complex valving while also reducing total plastic mass and shortening the axial profile of the dispenser. In this manner, the dispenser can be coupled to narrow-necked containers (?40 mm diameter) and dispense large doses (?1.2 mL). A locking collar secures the pump in a sealed, up-locked position, while also providing greater flexibility to adjust the air-to-liquid ratio to help impart the desired consistency to the dispensed foam product.

Abstract: A locking collar for a reciprocating pump is contemplated. The collar remains affixed to the pump to avoid the creation of unwanted waste, while simultaneously providing selectively uplocking. The collar includes axial one or more axial stoppers that cooperate with a peripheral stopper on the closure cap.

Abstract: A pump dispenser has a pump body and a reciprocable plunger with a lock-down mechanism, including internal or external lock formations of the plunger and body, such as thread formations, by which the plunger can be locked down for shipping and released subsequently by a rotational release movement. To supplement security for demanding shipping conditions the dispenser also has a supplementary catch mechanism in which respective catch formations of the plunger and body engage selectively in the locked-down position to inhibit the rotational release movement. The catch formations may have circumferentially-directed surfaces which engage between the underside of a plunger head having a shroud and a nozzle and the top of the body beneath the plunger head. They can be released by resilient deformation of one or more of the catch formations.

Abstract: A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the outer body and providing an external collar through which the plunger stem operates. The body insert has lock-down threads to lock down the plunger for shipping. The insert also has formations for blocking or unblocking the vent opening by rotation between the outer body and body insert, driven by rotation of the plunger head which makes a catch engagement with the top of the body insert. This plunger head rotation is the locking or unlocking action for the plunger lock-down. Blocking the vent during shipping reduces leakage.

Abstract: A fixed nozzle pump appropriate for food service and dispensing of other fluids of varying viscosities is contemplated. The components are modularly connectable for easy assembly and cleaning. A piston and sealing ring cooperate with the chamber extension formed in the pump body to facilitate reciprocating pump action while minimizing the number of components disposed in and exposed to the fluid flow path. A novel, injection-moldable valve is integrated on the dispensing nozzle. The entire assembly may be disposed within a container shell which itself includes a replaceable pouch filled with the fluid to be dispensed.

Abstract: A pump dispenser comprises an actuator head (100) having a dispensing channel communicating with a nozzle outlet (122), a closure body (20) having a top facing (203), at least one engagement feature extending axially upward from the top facing, and a recess (210) formed in the top facing. The recess has a cylindrical sidewall (212) with a plurality of axially-aligned stoppers positioned along the cylindrical sidewall and an annular ledge (220) defining an inlet port at a bottom end of the recess, said ledge including a cylindrical abutment (240) extending axially upward within the recess (210). An internal plug (40) is positioned within the annular recess, and includes an annular disk (400) with at least one axially-aligned stopping flange (410) positioned at or around a periphery of said disk and a plurality of axially-aligned engagement flanges (420) positioned toward a center of said disk.

Abstract: A biasing member for use in reciprocating dispenser pumps is contemplated. The member is made completely of polymeric materials and is suitable as a direct replacement for metallic coil springs. The biasing member includes spiral shape defined by inner and outer helix traces, with a series of perforations provided along one or both of those traces. These perforations, in conjunction with thinned channels, the size and shape of holes, and the size and shape of apertures, all cooperate to allow for a spring with sufficient resilience and greater spring force in comparison conventional, all-polymer biasing members.

Abstract: A pump constructed entirely from a polymeric material is described. The pump includes an internal sealing plug and adaptable insert coupled to a resilient bellows structure. The plug includes a keyed feature that allows for selective sealing at the lower end of the pump chamber depending upon the rotational alignment of the actuator head and closure, owing to stopper mechanisms appropriately positioned along the peripheral interfacing surfaces of these components.

Abstract: A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.

Abstract: A “smart” closure system, apparatus, and method are described. The closure includes mechanical solution, used in conjunction with wireless technologies and/or web-based or remote authentication, verification, and serialization via a mobile computing device, to provide information about the closure and the contents concealed within that closure. Further, the construction of the closure allows for any and all non-recyclable components of the wireless technologies to be removed so as to enable the closure to be recycled and/or converted to post consumer resin.

Abstract: A universal closure for a dispenser is contemplated. The closure seals to the container neck along three separate surfaces with sufficient force to enable the use of lockdown and/or anti-rotational features to secure the dispenser for e-commerce shipments. Provision of frictional projections secures a sufficiently tight fit between the container neck and the body insert of the closure so as to eliminate the need to force separate engagement features on the container itself.

Abstract: A trigger sprayer is made from a single grade of polymer capable of being reused as post consumer resin. The design allows for upright and inverted actuation. A pre-compression diaphragm ensures that dispensing stroke delivers a complete and uniform amount of fluid.

Abstract: A reciprocating foamer pump avoids problems encountered when conventional foamer pumps are exposed to freezing temperatures. In particular, the inventive pump provides an extra-secure connection between air and liquid piston members (200,300). Additionally, a tortuous air inlet (210) is provided to the foamer chamber (136) so as to prevent melted liquid from draining and accumulating in the air chamber.
