  • Patent number: 10898915
    Abstract: A sprayer system includes a sprayer head, at least two reservoirs, and a gripping portion. The reservoirs hold constituent components of a product. The product is emitted from a nozzle included in the sprayer head. The emission of the product results in the depletion of the components of one of the reservoirs to a greater extent than the remaining at least one reservoir and changes the center of gravity of the sprayer system.

  • Patent number: 10138110
    Abstract: A system for mixing and dispensing solution, such as a cleaning solution, includes a body with a first flow passage extending between a diluent inlet and an outlet, and a second flow passage extending between a concentrate inlet and the first flow passage. The system further includes a container for concentrate, with a container including a container valve. Moving the body axially toward the container to seat the body on the container opens the container valve for a flow of concentrate from the container to the first flow passage via the second flow passage. Further, moving the body axially away from the container to unseat the body from the container closes the container valve to the flow of concentrate.

  • Patent number: 9192949
    Abstract: A fluid application system includes a diluent reservoir, a chemical container, a sprayer housing, a manifold located in the sprayer housing, and a pump assembly in fluid communication with an outlet of the manifold. The manifold includes a diluent inlet in fluid communication with the diluent reservoir, a chemical inlet in fluid communication with the container, a mixing chamber in fluid communication with the diluent inlet and the chemical inlet and the outlet of the manifold. The pump assembly draws a mixture of the chemical and the diluent from the manifold and sprays the mixture of the chemical and the diluent from the nozzle.

  • Patent number: 9068662
    Abstract: A device to enhance sealing is provided. The device includes a body and a pressure cup. The pressure cup includes a channel, a first pressure channel, and a second pressure channel. The channel is formed in a surface of the body to surround a first portion of the surface. The channel is configured to hold an o-ring. The first pressure channel extends through the body and opens into the first portion of the surface. The second pressure channel extends through the body and opens into the channel. Pneumatic pressure within the second pressure channel is controlled to hold the o-ring in the channel when a second pressure within the first pressure channel changes.

  • Patent number: 8857738
    Abstract: A device (10) for selectively dispensing ones of multiple fluids, preferably cleaning agents, is disclosed. The device includes a reservoir (50) and a container assembly (100) that can include at least one container body (105, 110, 112, 114, 116). The reservoir (50) houses a diluent “D,” for example, water, and each container body houses a concentrate “C,” for example, a concentrated form of a cleaning agent. Each container body has an outlet assembly (200) with a nozzle (260), so that container assemblies (100) with multiple container bodies correspondingly include multiple nozzles (260). The diluent “D” and concentrates “C” are kept separate from each other, whereby ho end use product is stored in the device (10). Rather, end use product is mixed on demand during dispensation, as part of the, dispensing act. Namely, diluent “D” is pumped through an outlet assembly (200), drawing concentrate “C” thereinto which mixes into the end use product while exiting the device (10).

  • Patent number: 8777037
    Abstract: A device 10 for selectively dispensing ones of multiple fluids, preferably cleaning agents, is disclosed. The device includes a reservoir 50 that holds a diluent “D” therein and a housing 20 that includes a main body segment 22 and a head segment 26. A container assembly 100 may be held between the main body and head segments 22, 26. The container assembly may include at least one container body 105, 110, 112, 114, 116. Each container body 105, 110, 112, 114, 116 houses a concentrate “C,” for example, a concentrated form of a cleaning or other agent therein. The diluent “D” and concentrates “C” are kept separate from each other, whereby no end use product is stored in the device 10. Instead, end use product is mixed on demand during dispensation.
