Abstract: A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. An elastomeric pump element is positioned generally horizontally such that pulling the trigger retracts the element and releasing the trigger allows the element to extend. The sprayer includes a low cost spinner assembly and low cost valving to control the flow of liquid within the sprayer. In one aspect of the invention, the housing has front and rear sections with the rear section having a saddle portion and being hinged to the front section for pivotal movement from an open position for molding the housing to a closed position for operating the sprayer. In another aspect of the invention, the container has a rear portion which extends upwardly past the neck and defining a saddle recess, with the housing connected to the neck of the container and positioned forwardly of the upwardly extending container portion. The sprayer may include an elastomeric spring for biasing the pump element in the extended position.

Abstract: The hand pump sprayer and system for dispensing viscous liquids are provided. A nozzle is rotatably mounted around the delivery passageway of a hand pump sprayer. The nozzle is interconnected to the trigger of the hand pump sprayer so that the nozzle rotates, upon pulling of the trigger, simultaneously with the discharge of the liquid to the atmosphere. The nozzle rotates about an axis of rotation through the center of the discharge end of the nozzle through an angle of rotation from about 90.degree. to about 360.degree., desirably from 180.degree. to 360.degree. and preferably 270.degree. or more. Desirably the nozzle has two discharge outlets which direct fluid expelled from the hand pump sprayer along intersecting discharge axes. Simultaneously as the fluid is discharged along the intersecting axes, the nozzle is rotated about the axis of rotation. The resulting dispensed liquid has a high degree of atomization and a desirable round spray pattern.

Abstract: A pump dispenser connected to a container of liquid has a first piston reciprocatable in a first cylinder for pumping a quantity of liquid at each depression of the piston. A valve member received within a channel in the first piston is spring biassed into a position in which a dispensing outlet is normally closed and is movable to release liquid in response to excess liquid pressure in the first chamber. A cylindrical extension to the valve member defines a conduit communicating with liquid in the container and is separable from the valve member to open a liquid inlet port for recharging the first chamber. A second piston is movable in tandem with the first piston and cooperates with a second cylinder to provide suction on a return stroke of the pistons which is utilised to remove residual liquid from a dispensing channel delivering pumped liquid to a nozzle. Residual liquid collected in the second chamber is returned to the container during the next subsequent actuating stroke of the pistons. An actuator mounted on the first piston communicates lost motion to the second piston and provides valve action for applying suction to the dispensing channel. The dispenser is particularly useful for water borne liquid products because its self cleaning action prevents clogging.
Abstract translation: 连接到液体容器的泵分配器具有可在第一气缸中往复运动的第一活塞，用于在活塞的每个凹陷处泵送一定量的液体。 容纳在第一活塞中的通道内的阀构件被弹簧偏压到分配出口常闭的位置，并且可移动以响应于第一室中的过量液体压力而释放液体。 阀构件的圆柱形延伸部限定了与容器中的液体连通的导管，并且可与阀构件分离，以打开用于对第一腔室再充电的液体入口。 第二活塞可与第一活塞串联移动并与第二气缸配合，以在活塞的返回行程上提供抽吸，该活塞用于从分配通道移除残余液体，将分配通道输送到喷嘴。 收集在第二室中的剩余液体在活塞的随后的下一个致动冲程期间返回到容器中。 安装在第一活塞上的致动器将运动传递到第二活塞，并提供用于向分配通道施加吸力的阀动作。 分配器对于水性液体产品特别有用，因为其自清洁作用防止堵塞。

Abstract: A discharge apparatus for media has a medium pump and a compressed air pump, as well as control means through which, in stroke-dependent manner, precompression only takes place in the air pump during a first partial stroke and then during a further partial stroke delivery takes place from both pumps following a pressure-dependent opening of the delivery valve and finally during a further partial stroke delivery only takes place from the air pump. In order that the medium pump does not deliver to the outlet channel over intermediate and final partial strokes, delivery takes place back into the reservoir via the inlet channel.

Abstract: A trigger operated dispensing device for the discharge of fluids, particularly in a spray. The device comprises a housing including a trigger, which actuates a flexible pump. The flexible pump has an inlet accepting the fluid and an outlet end through which the fluid passes going to the discharge. The flexible pump, preferably of bellows type, is situated in line with and just adjacent to the discharge wherein rotational motion of the trigger results in rotational compression of the pump chamber. In a particularly preferred embodiment, the flexible pump further includes mechanical structure for imparting a radial momentum to the fluid prior to discharge.

Abstract: The adjustable nozzle assembly for a trigger sprayer comprises a nose bushing and an integral nozzle cap capable of being screwed upon the bushing. The nozzle cap has a discharge orifice located in its front face and a flange skirt extending from a front wall thereof. A nozzle cap flange skirt is threaded inside the rear portion thereof and an internally contoured or stepped surface is located forwardly of the threads to provide reduced diameter annular surfaces at two locations rearward of an inner wall surface of the cap and forward of the internal threads inside the nozzle cap flange skirt. The nozzle cap is screwed upon (threaded on) an externally threaded portion of the nose bushing and is selectively threadably positionable between three selective positions such that the positioning of the inner wall surface and the annular surfaces of the nozzle cap flange skirt selectively cooperate with a front face and annular periphery of a nose bushing face disc having two angular grooves in the annular periphery thereof thereby selectively to provide a stop mode position for containment of liquid, a spray mode position to discharge liquid in a spray pattern from the discharge orifice, and a stream mode position to discharge liquid in a stream pattern from the discharge orifice.

Abstract: A container and finger-depressible pump combination having improved non-leaking characteristics when the container holds a fluid (e.g., a volatile fluid such as nail polish remover) is described. The container which holds the fluid has a finger-depressible pump joined to its opened upper neck with the portion of the pump normally extending into the fluid in the container being encased in a closed but removable shroud which encases and isolates that portion of the pump and the adjacent portions of the pump from contact with the fluid. The shroud is a generally tubular structure being closed at its lower end and having circumferential flange means at its opposed open upper end which are adapted to be seated upon the upper land surface of the container neck underneath a portion of the cap holding the pump.

Abstract: The thrust piston pump of a delivery apparatus for liquid media and the like is provided with a valve arrangement in the suction passage. The valve arrangement has two valve seats acting in opposing manner and is associated with a single common valve body. This permits a rapid transfer of the valve body into the closed position engaging on the valve seat, particularly during operation in an inverted position. In addition, the discharge passage has a mechanically openable discharge valve which can be simply opened by displacing the actuating head of the pump with respect to a collar of the pump piston.
