Abstract: A method of molding a trigger sprayer one-piece housing includes molding the housing with a shroud having sides which extend rearward to an integral ergonomic saddle with a surface configured to rest upon the user's hand during trigger sprayer actuation. The one-piece housing is molded integrally with an outlet barrel, a pump cylinder, a vent passage cylinder, and a vertical inlet passage receptacle using the same three-piece mold.

Abstract: A fluid substance may be dispensed from a container with a fluid dispenser. The fluid dispenser has a housing connected to the container and a passage for providing fluid communication between a nozzle attached to the housing and the container. A pump positioned within the housing draws the fluid substance from the container interior and pushes the substance through an orifice in the nozzle. Attached to the housing is a pivotable door which is moveable between an open position wherein the fluid substance may be dispensed and a closed position wherein the door inhibits the fluid substance from being dispensed. The door has an aperture located remote from the nozzle orifice. Extending from the housing is a tongue which is configured to engage the aperture in the door when the door is in the closed position to prevent the door from being opened and to prevent the fluid substance from being dispensed from the nozzle orifice without first disengaging the tongue from the aperture and moving the door to the open position.
Abstract translation: 流体物质可以从具有流体分配器的容器中分配。 流体分配器具有连接到容器的壳体和用于在附接到壳体的喷嘴和容器之间提供流体连通的通道。 定位在壳体内的泵从容器内部吸取流体物质，并通过喷嘴中的孔推动物质。 连接到壳体的是可枢转的门，其可以在可以分配流体物质的打开位置和其中门禁止流体物质被分配的关闭位置之间移动。 门具有远离喷嘴孔的孔。 从壳体延伸的是舌部，当门处于关闭位置时，该舌头构造成与门中的孔啮合，以防止门被打开，并且防止流体物质从喷嘴孔口分配，而无需首先使舌头脱开 从孔中移动门到打开位置。

Abstract: The present invention pertains to a trigger sprayer which is connectable to two container volumes containing separate liquids. The sprayer has a trigger that is manipulated to draw the separate liquids into two separate pump chambers and then supply the two separate liquids from the pump chambers to a discharge passage of the sprayer. In the discharge passage the two separate liquids are mixed together prior to their being dispensed from the discharge passage as a spray.

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: A nozzle assembly for a trigger sprayer having a cap rotatable relative to a housing to establish the spray character of the fluid discharged and a slot and cam follower connection between the trigger sprayer housing and the cap with the cam shaped to impart an "off" condition, a gradually increasing spray condition, a combination spray and stream condition of gradually reversed relative influence, and a stream only condition. The different flow conditions are established by the interrelationship between a spinner head section and the cap that is rotatable along a path controlled by the cam and cam follower.

Abstract: A manually operable trigger sprayer is capable of dispensing a liquid from a container with the trigger sprayer alternately held in an upright orientation, in a downturned orientation and in an inverted orientation. In operation of the trigger sprayer in all three orientation positions, the liquid in the container is prevented from leaking through the vent passage of the trigger sprayer regardless of the level of liquid within the container.

Abstract: A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. A pump element is positioned generally horizontally such that pulling the trigger contracts or retracts the element and releasing the trigger permits the element to return to an extended position. An elastomeric spring is positioned between the housing and pump element to improve the return characteristics of the pump element. 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 upward past the neck and defines a saddle recess with the housing connected to the neck of the container and positioned forward of the upward extending container portion.
