Abstract: In a marking pen, the body of the marking pen containing the cartridge is made air tight except for the opening on the distal end to receive the marker nib and a vent hole. The walls of the pen body are made flexible and the vent hole is provided through the flexible walls near the distal end so that the cavity containing the cartridge can be pressurized by squeezing the body between the thumb and index finger, with the index finger covering the vent hole. The pressuring of the cartridge cavity applies hydraulic pressure to the nib to flush the nib with ink or unclog it.

Abstract: This invention relates to a writing tool for correction of misspelled words or a writing utensil such as a ball-point pen, in which air in a cap is pressurized in a process of pushing the cap onto and mounting the cap on an extremity end and the compressed air is forced into a liquid tank through an end of a tip to provide pressurization within the liquid tank. A distance from an opening end surface of a cap to an inner bottom portion of the cap is defined with respect to a distance from an end of a tip to near a cap loading base end of an extremity end. A resilient member is mounted on an outer periphery of the extremity end or in the cap for pushing back the cap to a normal mount position relative to the extremity end by releasing a pushing operation after the cap is pushed near the cap mounting base end. The cap can be automatically pushed back from the cap mounting base end to the normal mount position of the extremity end by means of the elastic member.

Abstract: A pressurized refill and a method for pressurizing a refill are provided. The refill has a plug secured at an end of the refill having multiple seals between the plug and an interior wall of the refill. A valve extends through a channel of the plug allowing pressurized gas to be forced into an interior of the refill to pressurize or re-pressurize the interior of the refill. A spring loaded stem maintains the valve in a closed and sealed position when pressurization is not being effected.

Abstract: A coating tool (12) comprises a coating tool body (2) having a liquid storage portion (2a) for storing a coating liquid, and a cap (10) detachably fitted and mounted on the coating tool body to be in tight contact with it. In the course of mounting the cap (10), the volume of a sealed space (A) formed in the cap (10) is decreased to supply air to the main barrel (2a), thereby pressurizing the interior of the main barrel (2a). At least one of an inner surface (10b1) of the cap (10) and an outer surface of a mouthpiece (2b) which are brought into tight contact with each other in the mounting operation of the cap (10) is coated with a sealing agent (16). In the coating tool for applying a correction liquid or the like, the ability to pressurize the interior of the liquid storage portion (2a) can be improved without complicating the structure in the cap (10), and the cap can be attached and detached smoothly.

Abstract: A pressurized refill and a method for pressurizing a refill are provided. The refill has a plug secured at an end of the refill having at least one seal and preferably two seals between the plug and an interior wall of the refill. A valve extends through a channel of the plug allowing pressurized gas to be forced into an interior of the refill to pressurize or re-pressurize the interior of the refill. A spring loaded stem maintains the valve in a closed and sealed position when pressurization is not being effected.

Abstract: A pneumatic dispenser for viscous fluids including a tubular pen barrel, a dispensing nozzle on one end of the pen barrel, and a pen cap constructed to sealingly receive the pen barrel. The pen cap also includes an air line connection and venturi arrangement so that when supplied with compressed air, air flow through the venturi reduces pressure in the pen and holds fluid in the pen. Interrupting air flow through the venturi causes pressure to increase in pen and fluid to be extruded through pen nozzle.

Abstract: An applicator in which the air within an inner barrel of a cap to the applicator is enabled to flow readily into the fluid tank of the applicator to increase the internal pressure of the fluid tank when the cap is engaged with the neck of the applicator, so that the fluid tank of the applicator need not be pressed between the fingers of a user for application of a highly viscous fluid. The inner barrel of the cap includes a curved, elastically deformable valve-opening member made of a highly flexible material bearing against the closed end of the cap. When the cap is engaged with the body of the applicator, the valve-opening member abuts against an application member to retract the application member from a caulked front edge of the tip of the applicator so as to form a clearance between the application member and the caulked front edge of the tip through which air can readily flow to increase the internal pressure of the fluid tank.

Abstract: A writing instrument has an ink reservoir under pressure. Compressed ink in the ink reservoir is supplied through an ink passage to a ball tip also acting as a valve body. A push rod is inserted in the ink passage and is intended to urge the ball forward. The ball tip is in a closed state when the writing instrument is used and is in an open state when the writing instrument is used for supplying ink. A stirring weight is housed in the ink reservoir. When the writing instrument is swung, the stirring weight is moved to stir ink in the ink reservoir. The stirring weight interferes with the push rod to displace it. The push rod is displaced to stir ink in the ink passage whereby ink containing air and/or air bubbles in the ink passage is removed.

Abstract: An inexpensive applicator in which the air within the inner barrel of a cap enters the fluid tank of the applicator to increase the internal pressure thereof in the process where the cap is engaged with the neck of the applicator, so that the fluid tank need not be pressed between the fingers for application of the fluid to be applied, the cap having in the inner barrel thereof a cylindrical valve member made of a highly flexible material and provided with a diaphragm or with a diaphragm having a ball-like portion formed thereon, and the application member being designed to be retracted and spaced from the caulked front edge of the tip when the application member is abutted against the diaphragm or the ball-like portion of the valve member in the process where the cap is engaged with the body of the applicator, whereas the elastically deformed diaphragm or the ball-like portion of the valve member is designed to close the front end opening of the tip when the cap is fully engaged with the neck.

Abstract: A fluid applicator in which the internal pressure of a fluid tank can selectively be increased, and the fluid to be applied is prevented from being discharged excessively during application. A cap is provided with a short first inner barrel and a long second inner barrel, so that, when the neck of the applicator is inserted into the short first inner barrel to seal the tip, the pressure rise in the first inner barrel is adapted to be small so as not to substantially increase the internal pressure of the fluid tank, whereas when the neck is inserted into the long second inner barrel, the pressure rise in the second inner barrel is adapted to be great so as to increase the internal pressure of the fluid tank. Alternatively, the applicator may be provided with a pressurizing device having a plurality of sealing barrels of different lengths.

Abstract: Disclosed is an applicator in which the air within the inner barrel of a cap is designed to enter into the fluid tank of the applicator to increase the internal pressure of the fluid tank in the process that the cap is engaged with the body of the applicator, so that the fluid tank need not be pressed between the fingers for application of the fluid to be applied. The cap has a valve member provided with a pushing piece disposed in the inner barrel thereof, and the application ball is designed to retract from the caulked front edge of the tip when the application ball is abutted against the pushing piece of the valve member in the process that the cap is engaged with the body of the applicator, whereas the application ball is designed to disengage from the pushing piece of the tip and resume contact with the caulked front edge of the tip when the cap is fully engaged with the body of the applicator.

Abstract: A method of applying fluid paint utilizes a marking device having a fluid paint-filled reservoir, a tip comprising a spring-loaded ball and its spring, and pressure means, such as collapsible walls or a pressure device, to apply pressure to the fluid. The paint, applied to a fabric as a decoration, is an oil-in-water emulsion in which oil mixture droplets (globules) are evenly dispersed in the water phase. The oil droplets are composed of an oil mixture preferably based on an oil-modified polyurethane or oil-modified alkyd or other oil-modified resin and drying agents. The oil-in-water emulsion contains a surfactant, a gellant, and an anti-foam agent. The pigment dispersion may be in the oil droplets or in the water phase.

Abstract: A liquid discharge device using a peristaltic pump having a depression and delivery system including an elastic tube for introducing compressed air into a liquid reservoir to be maintained in a selective pressurized state. A motor drive circuit is adjusted to vary motor rotation to sequentially squeeze and release one end of the elastic tube thereby varying the rate of pressurization in the reservoir.

Abstract: The disclosure is of a method and means for applying a flowable coating material, such as relining, to a tubular stack; e.g. chimney, flue or the like, by means of a distributor moved upwardly into the stack while supplying coating material to an upper surface of the distributor which is configured to cause the material to flow outwardly to the wall to adhere thereto. The apparatus includes selectively added extensions for moving the distributor incrementally through the length of stacks of considerable height, preferably by means of power-operated means; e.g., a fluid-pressure device.
