Abstract: A device and process for applying decorative paint to an article of clothing such as a T-shirt or sweatshirt. The device comprises a valve/nozzle assembly and a plurality of disposable, single-use cartridges of pressurized paint. The valve/nozzle assembly includes a threaded fitting having a piercing member extending therefrom that pierces a cover on a selected cartridge as the cartridge is threaded over the fitting. Upon piercing the cover, paint is forced upwardly into a valved passageway within the valve/nozzle assembly. A hinged lever is operatively coupled to the valve such that as the lever is depressed, a spray of paint is released through the nozzle at the end of the valve/nozzle assembly and onto the garment. Thereafter, the cartridge is removed and a second cartridge of paint thinner is attached to the valve/nozzle assembly. Again, the lever is depressed to release a spray of paint thinner through the valve/nozzle assembly for cleansing same.

Abstract: A fountain toothbrush has in its handle a toothpaste reservoir constantly pressurized by a charge of actuator gas acting through a cup-like piston disposed at the upstream end of the reservoir. The gas pressure pushes the piston and toothpaste downstream while resiliently urging the piston sidewall against the reservoir boundary wall to forwardly extrude toothpaste adjacent the boundary wall. A valve for selectively passing toothpaste from the reservoir to the brush head includes an apertured gate and a structurally separate actuator for translating the gate in a valve chamber in opposition to a bias spring. Separating the gate from the actuator permits the gate to be positively sealed against the chamber outlet by the toothpaste in the closed valve position. A lengthwise segment of the gate has a reduced thickness dimension so as not to fill the upstream side of the valve chamber, thereby avoiding the creation of a partial vacuum that would otherwise hold the gate in its open position.

An apparatus is also in cooperation with the channel in the head and neck for sealing the at least one lateral passageway, when not in use. This stops the flow of the teeth cleansing substance and prevents germs, bacteria, water and other foreign elements from contaminating the teeth cleansing substance left in the channel and the compartment.

Abstract: A snap-on cap for an aerosol shaving cream can is disclosed. An integral shaving cream brush is mounted in the cap so that when the cap is snapped onto a can of shaving cream the brush is held at an angle to the can body allowing for more convenient and efficient application of the foam. The cap is assembled in two pieces; a firm outer housing which provides a gripping surface and a flexible activator assembly which allows the cap to be easily snapped onto the aerosol can. The flexible activator assembly is comprised of an activator button rigidly connected to a nozzle by means of a strut. The nozzle and the activator button are each connected by a "hinge" to the brush forming a hinged parallelogram structure which provides sufficient flexibility to prevent activation of the aerosol can when the brush assembly is initially snapped onto the can. The hinged parallelogram allows vertical pressure to operate the can while preventing undesirable side-to-side movement of the activator button.

When the plug is removed, a delivery pipe sealingly carried by the vessel lid extends through the diaphragm and is received vertically within the paint container. A small opening in the diaphragm assures that the pressure internally and externally of the paint container will be substantially equalized. The delivery pipe is connected to a flexible feed tube, and the end of the feed tube is connected to a hand-held applicator. The applicator carries an on/off switch for interrupting the flow of paint to the applicator.
