Abstract: A miniature dispenser for dispensing fluid materials such as liquids or powders. The dispenser has a body which contains a piston and a material reservoir which is separable from the body and contains the fluid material. The material reservoir includes the passages, valves, and nozzles through which the material being dispensed flows and also includes an integral collapsible material container. A user may assemble the body to different material reservoirs and each material reservoir may be tailored to the properties of the material it contains. The dispenser is small enough to be worn as part of a bracelet or to be dipped to a pocket, belt, backpack, or purse.
Abstract: An apparatus for dispensing material includes: a chamber for the material, the chamber sealed by a flexible seal; a nozzle coupled to the chamber and residing at a front end; and a pump, the pump comprising: a piston that moves in a tube, and an activator. When a user presses the activator, the piston moves toward or away from the front end, and a portion of the material is emitted onto the user's palm or fingers. The pump emits the portion of the material regardless of a direction of gravitational pull. In one embodiment, the piston emits the material by directly contacting the material in the chamber. In another embodiment, air is allowed into the chamber through a weep hole, which resides between the piston and the material. The air is used to expel the material through the one-way valve.
