  • Publication number: 20160016188
    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. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

  • Patent number: 8403183
    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.

  • Patent number: 8328894
    Abstract: A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.

  • Patent number: 7635097
    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.

  • Patent number: 6971549
    Abstract: A bottle adapter is disclosed for use with a liquid refill kit for an automated cleansing sprayer of the type having a reservoir tray having an upwardly extending well for supporting a bottle in an inverted orientation, wherein the well has a spring-loaded outlet valve. The refill kit includes the bottle for containing a liquid. The bottle has a piercable closure sealing an end of the bottle. The adapter has a central hole. The adapter is suitable for being situated between the closure and a bottom wall of the upwardly extending well in the sprayer for supporting the bottle. The adapter is configured such that if the bottle and adapter are installed in the well, movement of the closure relative to the well can result in movement of the adapter which in turn can result in movement of the outlet valve that controls the opening and closing of the valve.

  • Patent number: 4998671
    Abstract: A multiple compartment flexible package having a receiving compartment adapted to contain one or more liquid impermeable, rupturable containers, a dispensing compartment containing an absorbent material and a passageway interposed between the compartments. Upon the application of pressure to the receiving compartment, the inner liquid container is ruptured and the liquid bursting from the inner container is directed by the passageway to the absorbent material within the dispensing compartment. The liquid contents of the inner container are absorbed by the absorbent material and dispensed therefrom at a rate depending upon the application of the package. The dispensing compartment may have a portion thereof permeable to the liquid contents or may have one or more apertures in one surface thereof adjacent the absorbent material.
