A pressurized pen having excellent feeling of using it by allowing an easy knocking operation with small force is disclosed. The pressurizing member 18 includes an elastic cylindrical member 19. The elastic cylindrical member 19 has a large-diameter front cylinder portion of which a front end 20a in air-tight manner communicates directly with the rear opening portion 6b of an ink containing tube 6 and which forms the pressurizing chamber 22, and a small-diameter rear cylinder portion 21 which is coaxially connected to a rear end of the front cylinder portion 20 and in which the front end portion 17a of the pressing member 17 is pressed into a rear aperture 21a thereof. The inside of the ink containing tube 6 is pressurized by allowing the pressing member 17 to press the rear cylinder portion 21 into the front cylinder portion 20 and compressing the elastic cylindrical member 19 in the axial direction with the pressing chamber 22 air-tight.

Disclosed is a pen adapted to be pressurized and capable of being manufactured with low cost, with which ink can be smoothly supplied and an excessive pressurization within an ink accommodating tube and the leakage of ink can be prevented, as well as a pen can be easily used in a state that a pen tip is directed upwardly. The pen comprises a pressurizing pump mechanism 10 which pressurizes an inside of ink accommodating tube 3 and includes a pressurizing chamber 14 communicating with the inside of the ink accommodating tube, an elastic spherical body 16 disposed to be pushed into the pressurizing chamber, a compression spring 17 that urges the spherical body in a direction to be released from within the pressurizing chamber, and a pressing stem 18 that moves forcedly the spherical body towards the front against the urging force of the compression spring to be pushed into the pressurizing chamber in an airtight state; the inside of the ink accommodating tube is pressurized by the operation of the pressing stem to push the spherical body into the pressurizing chamber against the urging force of the compression spring; and the spherical body is released from within the pressurizing chamber by the urging force of the compression spring in accordance with the pushing-release operation of the pressing stem to maintain the inside of the ink accommodating tube in a state ventilates with ambient air.
摘要:
In order to inhibit titanium oxide from settling down over a long period of time and secure a leveling property of a coating fluid including an ink composition, provided is a coating fluid for a fluid applicator, comprising at least titanium oxide, a resin and an organic solvent, wherein an additive comprising an N-acylamino acid derivative whose fundamental frame is at least one selected from N-acylamino acid amides and N-acylamino acid esters is added in an amount of 0.6 to 4.5% by weight based on the total amount of the ink composition, and a content of the resin described above is 1.5 to 11 parts by weight based on a content of 1 part by weight of the additive described above.
摘要:
An ink reservoir for a Writing instrument molded from a gas barrier resin such as polyvinyl alcohol, an ethylene vinyl alcohol copolymer resin, polyacrylonitrile, polyamide, a cellulose resin, polyester, polycarbonate and polystyrene, wherein a vapor-scarcely permeable coating layer having a vapor permeability (P1) of 0.5 g/m2* atm*24hr/25 μm or less at 40° and 90% RH is formed on the above reservoir for a writing instrument. In this ink reservoir for a writing instrument, a gas barrier property is not reduced under the environment of high moisture even if a wall of the ink reservoir is relatively thin and a resin having an excellent transparency is used, and releasing of pressurized air in the ink reservoir and falling of the tip member are not caused.

For producing a pressurized ball-point pen refill the ball-point pen refill includes a tip, an ink storage tube and a tail plug, wherein ink is filled in the space of the ink storage tube relatively near to the tip, and a pressuring gas is filled in the space of the ink storage tube relatively far from the tip. The tip includes a ball and a holder, and the ball is formed to have a surface roughness (Ra) of 0.010 μm to 0.080 μm. The holder has a ball house and an ink guiding groove, and the ball house has a side part and a bottom part. Moreover, a formula 1.01≦φB/φA ≦1.11 is satisfied when φA is the diameter of the ball, and φB is the inner diameter of the side part of the ball house.
摘要:
Provided is an ink-storing member for a writing instrument which can inhibit deterioration in the ink itself caused by permeation of oxygen and nitrogen contained in air, inhibit leaking of the ink and generation of bubbles, enhance discharge stability of the ink, improve fragrance retention of a perfume-containing ink, prevent inferior writing brought about by reduction in an internal pressure of an ink-storing vessel in a pressure type writing instrument and prevent deterioration in the ink due to vaporization of moisture of a water-based ink and deterioration in the ink caused by moisture absorption in an oil-based ink. Such ink-storing member for a writing instrument includes, for example, an ink-storing member for a writing instrument which is constituted of a multilayer structure comprising an organic high molecular compound layer constituted of an organic high molecular compound and an inorganic compound layer constituted of an inorganic compound.
摘要:
A writing instrument having a writing tip that responds to pressure applied during writing through the use of a cushioning element integrally formed with another part of the writing instrument. In a preferred embodiment, a writing instrument comprises a barrel, a cartridge with a writing tip, and an end plug with a cushioning element formed integrally with the end plug. The cartridge may be held in the barrel via the cushioning element, which is attached to the proximal end of the barrel. The end plug may be formed by an injection molding process. A stop element may be provided to inhibit or to prevent compression of the cushioning element after a predetermined degree of compression of cushioning element. The cushioning element may have a variable spring rate.
