Abstract: A valve for a dispenser pump is carried on a circular post or tube of a pump body. A protruding, sealing flange is formed at one end, while the opposing end includes tapering ribs extend along the inner surface of the hollow, tubular valve. In function, the ribs facilitate the passage of make-up air between the inner surface and the post/tube.

Abstract: A closing ring for a container and lid combination for securing the lid to the container includes a ring body having first and second free ends to be drawn together in order to secure the lid to the container. A link clevis and a lever clevis are welded to the free ends. A link is pivotally connected to the link clevis. A lever is pivotally connected to the lever clevis. The linkage arrangement is completed by connecting the link to the lever at a third pivot connection. A movable locking projection is assembled to the lever clevis for engaging the lever during an opening attempt wherein this engaging prevents the opening of the ring body until the movable locking projection is moved out of its engaging position relative to the lever.

Abstract: A container for storing and dispensing fluids includes a container body having an upwardly extending annular neck portion defining a container opening and terminating into an annular rim having a generally flat, upwardly facing sealing surface and an inwardly extending flange. A separate spout member includes an annular wall having an inwardly extending portion defining a pour spout and an outwardly extending lip at one end thereof, wherein the lip includes a downwardly facing sealing surface. The annular wall also includes an outwardly extending shoulder below the lip for engaging the rim flange, wherein the annular wall is configured to be received within the container opening and wherein the annular wall shoulder is capable of being snap-fit over the rim flange to create a seal between said rim sealing surface and said lip sealing surface. The container also includes a removable lid that threadedly engages the container neck.

Abstract: A fluid dispensing system includes a closure assembly. The closure assembly is configured to enclose a container opening. The closure assembly has a fluid supply tube with an opening and a shut-off valve threadedly coupled to the supply tube. The shut-off valve has a valve member configured to close the opening in the supply tube upon rotating the shut-off valve in a first direction and to open the opening in the supply tube upon rotating the shut-off valve in a second direction. A cap assembly is coupled to the closure assembly. The cap assembly has a connector member with a fluid passage fluidly coupled to the supply tube. The cap assembly is coupled to the shut-off valve to rotate the shut-off valve in the first direction and the second direction. The configuration of the system eliminates the need for spring-based valves.

Abstract: A container for the storage and dispensing of a liquid and which incorporates a sealing mechanism includes a blow-molded container body including a neck portion having a series of external threads and defining an annular, non-planar sealing surface, a pouring spout assembled into the body and a unitary closing lid including a series of internal threads constructed and arranged to engage the threads of the neck portion. The unitary closing lid includes the sealing mechanism in the form of a pair of annular sealing lips constructed and arranged to be compressed against the annular, non-planar sealing surface to establish a sealed interface between the closing lid and the body.

Abstract: A fluid dispensing system includes a pump for pumping fluid from a container. The pump has a vent opening for venting air into the fluid in the container to normalize pressure inside the container as the fluid is pumped. An intake shroud is coupled to the pump, and the shroud includes a channel opening to draw fluid from the container into the pump in a straw-like manner. A baffle is positioned between the vent opening and the channel opening of the shroud to reduce ingestion of the air into the pump so as to reduce short or inconsistent dosing of the fluid when pumped.

Abstract: A fluid dispenser comprising a pump assembly having a reciprocable plunger received in a housing having an outlet end for delivery of fluids. A handle is pivotally connected to the housing and is mechanically connected to the plunger of the pump assembly to provide a mechanical advantage. A flexible internal tube connects the reciprocable plunger to a fixed outlet from the housing. The unit may be field stripped without any special tools.

Abstract: A fluid dispensing system includes a pump body configured to couple to a container. The pump body defines fluid inlet openings and a pump cavity. A shroud cover covers the pump body to draw fluid from the container. An inlet valve allows fluid from the container to enter the pump cavity through the fluid inlet openings. A plunger is slidably received in the pump cavity, and the plunger defines a fluid passage with a dispensing opening through which the fluid is dispensed. A shipping seal seals the fluid passage during shipping to minimize leakage of the fluid during shipping. An outlet valve is disposed inside the fluid passage to minimize the height of the fluid between the outlet valve and the dispensing opening so as to minimize dripping of fluid from the dispensing opening. The pump body includes a venting structure to normalize the air pressure inside the system.

Abstract: A sealing mechanism for a container for sealing an interface between two or more of the structural members, including a container body, a pouring spout, and a closing cap, includes an outer annular edge formed as part of a threaded neck opening for the container body, a radial lip formed as part of the pouring spout and being positioned in contact with the neck portion and the closing cap being configured so as to be attachable to the container body for closing the opening and being constructed and arranged so as to seal against the outer annular edge when attached to the container body.

Abstract: A fluid dispensing closure which incorporates a dispensing valve to control fluid flow through the closure and a vent passageway to vent air into the container as necessary. The closure includes a dispensing spout capable of mating engagement with a receiving container. The dispenser spout has a fluid passageway with a resilient valve made from an elastomeric material seated therein. The vent passageway formed in the closure is selectively sealed by a grommet depending upon the vacuum created within the container as the fluid is being dispensed from the container. A removable overcap sealingly covers the dispensing spout to capture any fluid leakage.

Abstract: A large bore tubing roller clamp assembly for regulating the flow rate of a liquid through large bore tubing is disclosed. The roller clamp assembly comprises a substantially rigid elongated plastic frame, a generally cylindrical roller, and a length of a large bore tubing disposed within the frame. The flow rate through the tubing is controlled by moving the roller along an inclined roller track and over the tubing, thereby selectively compressing tubing to attain the desired flow rate.
