    摘要: A cap, spinner, and discharge nozzle assembly for use with a liquid dispensing apparatus such as a trigger sprayer. The spinner assembly can be externally fitted to the discharge nozzle, and includes an annular chamber surrounding a central post having a swirl chamber in its top. The central post includes longitudinal grooves, communicating with tangential grooves in an annular wall defining the swirl chamber. Apertures are provided in the base of the annular chamber such that pressurized liquid flows through the apertures and into the annular chamber, with a resulting reduction of velocity, and then along the longitudinal grooves and through the tangential grooves into the swirl chamber. A cap is provided which variably engages the discharge nozzle and which has at least a central projection on the inner side of its front face, and preferably an annular groove formed by an outer projection surrounding the central projection. The central projection may reversibly seal against the floor and/or annular wall of the swirl chamber, and the annular groove may seal over the annular wall.

    摘要: A dispenser comprises a container for containing fluid to be dispensed and a manually operated reciprocating fluid pump to be secured to the container. The fluid pump includes a pump mechanism, an intake port adapted for fluid communication with liquid contained in the container, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port, a closure cap portion configured for securing the fluid pump to the container, and a seal portion engageable with the container for providing a fluid-tight seal between the fluid pump and the container. The container includes a neck having a mouth therein for passage therethrough of liquid in the container. The container further includes a flange circumscribing the neck of the container. The closure cap portion comprises a generally annular-shaped skirt, and at least three protrusions extending generally radially inwardly from an inside surface of the skirt. The protrusions are circumferentially spaced from each other along the inside surface of the skirt. The protrusions of the closure cap and the flange of the container are configured for a resilient snap-fit engagement of the protrusions with the generally downwardly facing surface of the flange when the seal portion of the fluid pump is brought into engagement with the container to releasably maintain the seal portion in fluid-tight sealing engagement with the container.

    摘要: On a manually operated reciprocating liquid pump, comprising a plunger mounted for reciprocating movement between charge and discharge positions in a pump housing, a lock mechanism on the pump selectively locks the plunger in its charge and discharge positions relative to the pump housing. Seals are also provided that prevent leakage through the pump when the plunger is in its charge and discharge positions.

    摘要: A trigger sprayer comprises a dispenser body, a pump mechanism adjacent the dispenser body, a trigger adjacent the pump mechanism, and a plug. The dispenser body has an intake port adapted for fluid communication with a source of liquid, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port. The pump mechanism includes a pump element reciprocally moveable relative to the dispenser body to draw fluid in through the intake port and force it out through the discharge port. The trigger is moveable relative to the dispenser body between forward and rearward positions and is located and configured to cause the pump element to move from its first position to its second position when the trigger is moved from its forward position to its rearward position. The plug is connected to the trigger and moveable relative to the dispenser body between a blocking position in which it covers the discharge port and an unblocking position in which it is laterally spaced from the discharge port to avoid interference with the discharge of fluid through the discharge port. The trigger and plug are configured so that movement of the trigger between its forward and rearward positions causes movement of the plug between its blocking and unblocking positions.

    摘要: A liquid dispenser comprising a dispenser body having a pump mechanism defining a variable volume fluid receiving cavity. A cylindric formation, smaller than the fluid receiving cavity, is within the cavity and a vent passageway is in fluid communication with the cylindric formation. A plunger is reciprocally moveable within the cylindric formation and is configured for moving with the pump mechanism as the pump mechanism is moved between extended and contracted positions. The plunger and cylindric formation are configured such that the vent passageway is in fluid communication with the fluid receiving cavity of the pump mechanism when the pump mechanism is in its contracted position and is configured to block fluid communication between the vent passageway and the fluid receiving cavity when the pump mechanism is in its extended position.
