  • Patent number: 9267767
    Abstract: A portable self-defense spray to protect a person from danger under an emergency situation is provided. The compressive-spray structure includes a compact case manufactured in various designs by using a flexible long-length filling tube filled with the CN solution. In a typical spray structure, CN solution is always sprayed at only a right position, the filled CN solution is not completely exhausted, and the design of the self-defense spray is limited. The filling tube to receive the CN solution is provided in the case without being twisted. The vacuum pump operating member cooperating with the button member having the spray port is installed at one side of the filing tube. A cap is provided at an opposite side of the filling tube for the sealing purpose. Vacuum is generated with the pressing of the button member, so that the CN solution in the filling tube is sprayed due to compression.

  • Patent number: 8936416
    Abstract: A portable air abrasion device has a dispensing chamber and a flow valve for controlling the flow rate from the dispensing chamber. The flow valve includes a fluid flow chamber for receiving granular materials exiting the dispensing chamber. The fluid flow chamber has a granular materials inlet port, a fluid flow inlet port for receiving the flow of a fluid to the fluid flow chamber and a fluidized granular material exit port for dispensing a fluidized mixture of the granular material away from the fluid flow chamber. The fluid flow chamber also has a flow regulator employing a lead screw to control the flow of fluidized granular material through the fluidized granular material exit port.

  • Patent number: 8651337
    Abstract: A dispenser is provided including a dispenser housing that receives disposable refill units that are to be replaced when empty. The dispenser housing includes an air compressor and an inflation plug. The inflation plug includes a needle having an outlet and further includes a vent valve in fluid communication with the outlet. The inflation plug is fluidly associated with the air compressor such that the air compressor selectively advances air to the vent valve and to the outlet of the needle. The disposable refill includes a container having an interior with a liquid portion and air portion therein. The container further includes a plug receipt, and the inflation plug of the dispenser housing engages the plug receipt such that the outlet of the needle communicates with the interior of the container.

  • Patent number: 8052013
    Abstract: A liquid crystal dispensing apparatus includes a needle sheet formed as a unitary piece for dispensing liquid crystal material contained within a liquid crystal container through a nozzle by selectively contacting a needle. The needle sheet includes a needle contacting portion for contacting the needle and a coupling portion for coupling the liquid crystal container to the nozzle. Therefore liquid crystal material is prevented from remaining within the needle sheet and the needle sheet can be easily cleaned.

  • Publication number: 20100252576
    Abstract: Apparatus and methods for dispensing small amounts of a viscous material onto a workpiece. The narrow-profile dispensing apparatus includes a fluid chamber, a nozzle, and a valve seat disk representing individual components that are removable from a main body of the dispensing apparatus for cleaning and/or replacement. The nozzle is coupled with the fluid chamber by a heat transfer body that may be cooled by, for example, a cooling fluid routed through an air pathway defined in the heat transfer body. The main body of the dispensing apparatus may be cooled by air exhausted from an air cavity of a pneumatic actuator regulating the movement of a needle to control the flow of viscous material in the dispensing apparatus.

  • Patent number: 7798364
    Abstract: The present invention relates generally to a toy water gun and, more particularly, to a pressurized toy water gun having a mixing nozzle or nozzles for simultaneously discharging and mixing two or more liquids after they pass through the mixing nozzle. In one embodiment, the toy gun may include separate tanks or reservoirs for storing the liquids, and separate nozzles for receiving and discharging the liquids in discharged streams of liquid. The toy gun may further include a pressurization mechanism in fluid communication with the tanks and the nozzles to provide pressure to cause the liquids to be discharged from the nozzles in the discharged streams of liquid. The nozzles may be oriented relative to each other such that the discharged streams engage each other after being discharged from the outlets of the nozzles to mix the liquids.

  • Publication number: 20090020553
    Abstract: A fluid dispensing apparatus includes a pulse generator coupled to a pump that operates in discrete cycles. Each cycle includes a first part in which fluid is drawn into the pump through an inlet, and a second part in which fluid is expelled from the pump through an outlet. Each cycle results in a discrete, consistent volume of fluid being expelled. The pulse generator transmits discrete pulses to the pump, causing the pump to operate for a set number of cycles per pulse. The total number of cycles is a multiple of the number of pulses transmitted, so that the number of pulses determines the volume of fluid dispensed. Alternatively, the pump is driven through increments of the second part of the cycle, with the number of pulses supplied to the pump determining the proportion of the second part of the cycle completed, and therefore the volume of fluid dispensed.
