A device for dosed dispensing of a fluid medium is provided with a pen-like housing which has a storage chamber for accommodating the fluid medium and which has at its front end a tip in which there is provided an outlet opening for the fluid medium. Arranged in the front end is a valve element which closes the outlet opening under the force of a spring and is arranged such that it at least partially opens the outlet opening in the event of radial pressure being applied from the outside on the front end of the housing. The valve element is arranged in a tiltable manner at the outlet opening.

Pen-type hazardous material applicators are provided useful in applying metal pretreatment material to intricate geometries, such as blind holes, through holes, rivets, crevices, chamfers, counterbores, countersinks and other difficult to access surfaces are provided.

A fountain pen that is configured to be reloaded with ink wherein the fountain pen of the present invention has an improved volume capacity over conventional fountain pens. The invention includes a body wherein the body includes a grip portion and a barrel portion that are rotatably coupled. A nib is secured to the first end of the body. A rod member is mounted within the interior volume of the body and extends the length thereof. A piston head member is operably coupled to the rod member and is configured to traverse therealong during rotation of the barrel portion of the body. The wall member of the barrel portion of the body includes movement members formed thereon. The perimeter edge of the piston head member is sealably and operably coupled with the movement members and wherein movement of the piston head member facilitates the drawing of ink into the body.

The invention relates to a device for applying a viscous substance, in particular for the purposes of cosmetics, writing, painting, drawing, and/or marking, with a tank (40) for storing a liquid substance, a pump cage (42) arranged within the tank (40), an application apparatus (2), and a conveying device (3), which is configured such as to convey the substance out of the tank (40) to the application device. According to the invention, provision is made for the conveying device (3) to comprise a cylinder (10), a piston (30) arranged such as to be axially displaceable in the cylinder, a pump plunger (20) for the axial displacement of the piston (30) and having a plunger hole (26), a first connection channel (41) between the cylinder (10) pump cage (42) and the tank (40), and a second connection channel (21) between the cylinder (10) pump cage (42) and the application apparatus (2), plunger hole (26) the piston (30) to be adjustable in relation to the pump plunger (20), for the piston (30) to open or close the first connection channel (41) depending on the setting in relation to the cylinder (10), and for the piston (30), depending on the position in relation to the pump plunger (20), to open or close the second connection channel (21).

Pen-type hazardous material applicators are provided having features useful in applying metal pretreatment material to intricate geometries, such as blind holes, through holes, rivets, crevices, chamfers, counterbores, countersinks and other difficult to access surfaces.

A cosmetic applicator capable of stably applying a cosmetic even when the cosmetic contains large particles. A cosmetic applicator includes a barrel, a brush made of bundled fibers and provided in front of the barrel, a cosmetic accommodation portion arranged in a space behind the barrel, a guide that guides a cosmetic from the cosmetic accommodation portion to the brush, a collector that has a comb-shaped outer circumferential surface and that is disposed inside the barrel and at an outer circumferential portion of the guide, and a front barrel supporting the brush at a front portion of the barrel. A capillary force of the guide is 50 to 200 (mm) (as measured using purified water in an environment of 25 C.). (B)/(A) is 0.8 or greater, where (A) (mg) is an amount of cosmetic liquid discharged for 1 (m), and (B) (mg) is an amount of cosmetic liquid discharged for 1 (m) after 30 (m).

A vented output device for uniformly mixed liquid comprising a barrel defining a reservoir for containing the uniformly mixed liquid, and at least one vent channel extending from a first vent opening in fluid flow communication with an exterior of the device and second vent opening in fluid flow communication with the reservoir. A binary ink storage assembly includes multiple glass ampoules arranged in pairs, which are placed inside the barrel in parallel. The invention provides a reliable, simple and low-cost output device for solving the problem of not allowing the liquid to be uniformly mixed and output when a chemiluminescent marker or pen is activated.

A filling system for a fountain pen includes a pump unit, an air channel connected to the pump unit and to a first connection for connecting to the fountain pen, and an ink channel separate from the air channel and having an immersion end for immersing in ink and which is connected to a second connection for connecting to the fountain pen. The pump unit is designed to introduce a specified air volume into the air channel with positive pressure in order to flush ink out of the fountain pen and subsequently apply a negative pressure to the air channel such that a specified ink volume is suctioned out of the ink channel into the fountain pen.
