Abstract: The applicator includes a housing having an outer surface, and an internal reservoir for holding the dispensable product (e.g., liquid soap or topical skin treatment or any flowable product). Porous qualities of the housing fluidly couple the internal reservoir and the outer surface of the housing. Thus, when the applicator is activated by creating an internal positive pressure, the product continuously flows (e.g., for 10 seconds or more) from the internal reservoir to the outer housing surface. A rapid product release (e.g., 1 to 9 seconds) is also possible. One or more porous housing jackets may be disposed about the housing, which operate in conjunction with the porous housing to control flow of product. The applicator can be designed as a one-time disposable device that includes an internal supply of product, avoiding the need for both applicator and separate product. Alternatively, the applicator can be designed to be rechargeable with a particular product or products.

Abstract: A toothbrush with integrated toothpaste dispenser includes a brush section, a handle section and an intermediate neck section. Positioned among the bristles of the brush section is a soft, flexible tube—the external end of which is just below the level of the ends of the bristles. This flexible tube allows for the delivery of the toothpaste to the ends of the bristles in an efficient and practical manner. Within the handle section resides a reservoir of toothpaste. The intermediate neck section is hollow, which forms a communicating channel for the toothpaste to travel from the toothpaste reservoir in the handle to the toothbrush head. Dispensing of the toothpaste can be accomplished by any manner of delivery system. The types of delivery systems possible include, but are not limited to: pump systems, lever systems, screwdiven systems and roller systems.

In order to simplify the recharging of the ink, and to be able to operate with the least possible electrical energy, the present invention utilizes as a recharge valve a tube pump which is rotatably driven by an electric motor and also can generate the pressure necessary to convey the ink to the secondary ink reservoir.

Abstract: A cleaning system utilizing a hollow bodied, disposable dispensing capsule or package comprising a storage chamber and integral dispensing chamber made of a plastic material. The package is connected to the system handle via a conical protrusion on the package closure. An orifice separating the two chambers is provided with a movable, inlet clapper valve, the dispensing chamber outlet orifice being normally closed by a spring urged valve. Deformation of the elastic walls of the bellows shaped dispensing chamber dispenses a discrete amount of liquid to the system handle without relying on gravity. Compression of the dispensing chamber reduces the volume thereof, closes the inlet clapper valve, and opens the outlet valve to dispense the product. The conically shaped storage chamber provides for ready pumping and evacuation of cleaning fluid therefrom, the flexible walls collapsing inward as a result of the vacuum created by the decompression of the dispensing chamber.
