  • Patent number: 9033606
    Abstract: A container adapted to contain and dispense a product and method for its use. The container comprises a hollow body, a filling opening, a dispensing opening, a valve and a resiliently deformable means for said valve. The valve may form a leak-tight engagement with the dispensing opening, and is openable by an external force acting on said valve whereby the leak-tight engagement is disengaged, allowing the product to be spread onto a fabric by the valve. The container may be used in a method for pretreating and subsequently laundering pretreated fabrics in an automatic washing machine.

  • Patent number: 6918711
    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.

  • Patent number: 6257791
    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.

    Abstract: An ink supply system for writing instruments which operate with liquid ink. The writing instrument has a large-volume ink reservoir which communicates via a recharge valve with a small-volume ink reservoir which is adjacent to the writing element. The transmission of ink from the large-volume ink reservoir to the secondary reservoir is controlled by a sensor as a function of the quantity of ink which is present in the secondary ink reservoir. 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.

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.
