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.

Fluid application system

A container can be configured for use with an attachment for mixing and dispensing a solution. The container can include an outlet opening for flow out of the container, and a container valve that is configured to control the flow out of the outlet opening. A neck of the container can be oblong, can include a first attachment flange and a second attachment flange, or can include a first attachment shelf and a second attachment shelf.

Attachment and system for mixing and dispensing a chemical and diluent

A container includes a reservoir holding a non-pressurized product. A metering device and valve assembly are within the reservoir. The valve assembly includes a product intake conduit and a spring biased valve stem. The valve stem is at least one of an upwardly extending conduit or reciprocating conduit, which is in fluid communication with the product intake conduit.

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.

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.

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.

Valve block assembly

A device () for selectively dispensing ones of multiple fluids, preferably cleaning agents, is disclosed. The device includes a reservoir () and a container assembly () that can include at least one container body (). The reservoir () 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 () with a nozzle (), so that container assemblies () with multiple container bodies correspondingly include multiple nozzles (). The diluent &#x201c;D&#x201d; and concentrates &#x201c;C&#x201d; are kept separate from each other, whereby ho end use product is stored in the device (). Rather, end use product is mixed on demand during dispensation, as part of the, dispensing act. Namely, diluent &#x201c;D&#x201d; is pumped through an outlet assembly (), drawing concentrate &#x201c;C&#x201d; thereinto which mixes into the end use product while exiting the device ().

Refillable devices for dispensing fluids

A devicefor selectively dispensing ones of multiple fluids, preferably cleaning agents, is disclosed. The device includes a reservoirthat holds a diluent 'D' therein and a housingthat includes a main body segmentand a head segment. A container assemblymay be held between the main body and head segments. The container assembly may include at least one container body. Each container bodyhouses a concentrate 'C,' for example, a concentrated form of a cleaning or other agent therein. The diluent &#x201c;D&#x201d; and concentrates &#x201c;C&#x201d; are kept separate from each other, whereby no end use product is stored in the device. Instead, end use product is mixed on demand during dispensation.

Container for a dispenser

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.

Container with dip tube holder

A dental x-ray sensor holder includes at least two clamping faces wherein at least one of the faces includes at least one and preferably a plurality of resiliently deformable gripping protrusions. The clamping faces are positioned in a moveable, spaced opposing relation, such that the faces may be physically moved together to physically impinge the x-ray sensor therebetween.
