  • Patent number: 10406545
    Abstract: A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

  • Patent number: 9839927
    Abstract: A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser (100), configured to draw fluid up from a container. A nozzle assembly can include a nozzle (160), and a nozzle slide (112). The nozzle slide can be configured to slide and/or rotate relative to the shroud (102) to provide different dispensing modes. In alternative examples, the nozzle (160) can be configured to rotate in 30 degree increments relative to the shroud (102) to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle.

  • Publication number: 20080105713
    Abstract: A device for that places a fluid container in fluid communication with a sprayer is disclosed. The device includes a container adapter that allows a dip tube to be attached to the fluid container rather than the sprayer. When the sprayer is removed from the fluid container, the dip tube stays in the fluid container. Refill fluid containers may come with the container adapter and dip tube installed. When the sprayer is attached to the fluid container, the adapter seals against the sprayer allowing fluid to be pumped from the fluid container by the sprayer. A sprayer connector with geometry that matches an inner or outer shape of the adapter is attached to and/or built into the sprayer. The sprayer connector is constructed to allow easy alignment of the sprayer to the fluid container. The sprayer connector and the container adapter also provide a unique attachment geometry to insure only containers with formulae compatible to the sprayer are pumped through the sprayer.

  • Publication number: 20080048050
    Abstract: An automated sprayer for spraying the walls of a shower enclosure with a liquid cleanser dispenses the cleanser using a pump and rotatable spray head. A motor drives the pump and rotates the spray head. The sprayer has a showerhead mountable housing with a hanger. The housing supports a bottle of cleanser in an inverted fashion. Cleanser is delivered from the bottle through a cleanser conduit in the piercing post into a well of the housing. The bottle is vented from the well through an air vent path in the piercing post or from a well vent outlet through the air vent path in the piercing post. An outlet valve in the well permits outflow of cleanser from the well. Various bottle caps and bottle closures are also provided to improve venting and/or limit cleanser leakage from the bottle when the bottle is installed in the housing.
