Patent number: 10898915Abstract: 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.Type: GrantFiled: May 20, 2019Date of Patent: January 26, 2021Assignee: S. C. Johnson & Son, Inc.Inventors: Christopher F. Lang, James R. Crapser, Thomas A. Helf, Jeffrey L. Crull, Evan A. Sparks, Cunjiang Cheng

Patent number: 10138110Abstract: 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.Type: GrantFiled: September 21, 2016Date of Patent: November 27, 2018Assignee: S.

Patent number: 9068662Abstract: 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.Type: GrantFiled: October 30, 2013Date of Patent: June 30, 2015Assignee: Semba Biosciences, Inc.Inventors: Andrew Paul Wilke, Robert Charles Mierendorf, Anthony Charles Grabski, Cunjiang Cheng

Patent number: 8857738Abstract: 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).Type: GrantFiled: March 26, 2008Date of Patent: October 14, 2014Assignee: S.C. Johnson & Son, Inc.Inventors: Jeremy F. Knopow, Jeffrey L. Crull, Lawrence J. Fenske, Cunjiang Cheng

Patent number: 8777065Abstract: A container for use with a handheld fluid dispenser is provided. The container may include a container body having interconnected walls that define an inside space therebetween and in which liquid contents are held. An opening may extend through the container body and permit access to the liquid contents in the container body. A cap may engage the container body and be aligned with the opening of the container body. The cap may include a rim that defines an outer portion of the cap. A neck may be arranged concentrically within the rim, the neck including a bore that extends longitudinally through the neck and is aligned with the opening of the container body. A recess that has an annular shape may be defined between the rim and the neck of the cap.Type: GrantFiled: February 21, 2012Date of Patent: July 15, 2014Assignee: S.C.

Patent number: 8777037Abstract: 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.Type: GrantFiled: June 17, 2010Date of Patent: July 15, 2014Assignee: S.C. Johnson & Son, Inc.Inventors: Jeremy F. Knopow, Jeffrey L.
