  • Publication number: 20150108166
    Abstract: A device for mixing and dispensing at least two flowable components comprises a housing front face with an outlet for the components and a piston having a piston front face. The piston is arranged such that the piston front face and the housing front face are facing each other. The piston front face and the housing front face are adapted to form a channel for the components between each other. The device is adapted to reduce the channel upon urging the piston front face and the housing front face against each other and thereby to displace the components to flow toward the outlet. The device facilitates mixing and dispensing a multi-component dental material.

  • Patent number: 8978936
    Abstract: A apparatus for delivering a predetermined quantity of content from a pressurized container includes a dispensing assembly which sits on the container and connects with an upper portion of a valve stem of the valve assembly, wherein the dispensing assembly includes a) an actuator cap having a discharge passage, which is open or obstructed and wherein the actuator cap acts as a metering chamber in combination with b) an adaptor which fits inside the cap and also snuggly engages the valve stem. The cap fits snuggly over the adjuster to define a metering chamber which depending on its position can close off the metered chamber or open it to the dispensing conduit\nozzle. When the cap is depressed it pushes down on the adjuster which depresses the valve. The chamber fills, but nothing is released until the upstroke.

    Abstract: A dispensing assembly includes a cartridge for containing a fluid and a mixer for mixing and dispensing the fluid. The cartridge includes a locking flange or wall and the mixer includes a locking latch configured to snap into and out of engagement with the locking flange. To this end, the mixer and the cartridge are coupled and uncoupled by a snap-on and snap-off engagement that does not require relative rotation of the mixer and the cartridge. The locking latch also includes a latch release mechanism such as a squeeze handle, a peel handle, or a locking ring for forcing the locking latch into and out of engagement with the locking flange. As a result, the connection of the mixer and the cartridge is a quick and easy process and cross contamination of fluids in multiple fluid cartridges is avoided.

  • Patent number: 8678238
    Abstract: A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. The liquid ejecting element is connected to a force transmitting yoke. The yoke responds to pressurized fluid from the source to generate the motive force on the ejecting element.
