摘要:
An ink composition for such a pressurized ball-point pen as is excellent in writing characteristics and is free from ink leakage to thereby be suitable for handwriting; and a pressurized ball-point pen. This ink composition for pressurized ball-point pen is one at least comprising a colorant, a solvent and silica wherein aggregates at least containing silica are contained and which ink composition exhibits a viscosity of 10,000 to 40,000 mPa.sec at 25ºC. The pressurized ball-point pen may be one comprising a closed contained and, accommodated therein, an ink filling tube filled with the above ink composition for pressurized ball-point pen together with a refill having a pressure gas sealed therein.

A liquid applying tool is provided which can create pressurizing action with a simple structure and without any labor at the time of using the liquid applying tool, and allows liquid to be smoothly fed to a tip end of a liquid applicator member with the assistance of the pressurizing action. The liquid applicator comprises a liquid storage container 13 having liquid L stored therein and a liquid applicator member 15 provided at a tip end portion thereof, an outer container 12, the liquid storage container 13 being housed in the outer container 12 with at least a tip end of the liquid applicator member 15 being exposed to an outside of the outer container, a cap 20 removably attached to a tip end portion of the outer container 12 to cover the tip end of the liquid applicator member 15, a compression member 40 arranged in the outer container 12 and provided at a rear end portion of the liquid storage container 13, a forward biasing member 62 for causing the compression member to be biased axially forward, and a power transmitting member 60 provided in the outer container 12. The power transmitting member 60 is adapted to be reciprocation-moved in the axial direction in the outer container 12 according to attaching/detaching of the cap 20, whereby the compression member 40 is reciprocation-moved with respect to the liquid storage container 13 in the axial direction.

The invention relates to a liquid supply device utilizing a rotating cam mechanism for supplying a liquid. In the liquid supply device for smoothly supplying a liquid with the assistance of pressurizing action, switching operation by the rotating cam mechanism can be carried out reliably. A liquid housing tube 14 housing a liquid is disposed to be movable in an axial direction in an outer shaft and has a tip end chip 32 movable between a protruding position from a tip end of the outer shaft and a retracting position in the outer shaft. A rotating cam mechanism 16 which can move the liquid housing tube 14 forward and backward includes a rotating cam 40 movable between a front position and a rear position and a pressurizing space 18 to be compressed to be able to pressurize an inside of the liquid housing tube 14 when the tip end chip 32 is in the protruding position is provided in a rear portion in the rotating cam 40.

Provided is a pressurized pen, which is enabled to enhance the sealing property of a compression chamber (25) at a pressurizing time in the knocking operation of a knock mechanism (10) and to improve the durability. A pressuring pump mechanism (16) includes: a pressure member (20) having a front end opening portion communicating with the inside of a medium containing tube (6) and a compression chamber (25) made extensible and contractible in axial direction; and a push member (17) for coming in axial direction into and out of abutment against a rear end opening portion of the pressure member (20) and for pushing the compression chamber (25) of the pressure member (20) in a gas-tight condition in a compressing direction. The push member (17) is associated with the pushing action of a knock mechanism (10) such that it is enabled to irrotationally move toward the rear end opening portion of the pressure member (20).
摘要:
A writing device (10) generally including a uniformly cylindrical main body (12) partially filled with a writing medium such as ink (14). A writing tip (19) is inserted into a first end (16) of the main body (12) and a first sealing member (24) is inserted into the second end (20) thereof. The first sealing member (24) is located in the main body (12) near the second end (20). A pressurized gas such as nitrogen (26) is disposed in the body (12) between the ink (14) and the first sealing member (24). Alternatively, a gas forming means may be located in the main body (12) to continually produce a gas as the ink (14) is depleted to maintain pressure therein. A second sealing member (28) is inserted into the second end (20) of the main body (12) to provide a dual seal gas pressurized system.
摘要:
A gas-pressurized writing instrument simply constructed so that a compressed gas will not escape to the outside by providing a writing point assembly (10) at the front end (14a) of a tube member (14), storing an ink (12) to be fed to the writing point assembly (10) in the tube member (14), encasing at least part of the tube member (10) by a casing cylinder (18) so as to form a space (16) communicating with the rear opening of tube member (14), and sealing a compressed gas inside the space (16) so that the compressed gas will push the ink out to writing point assembly (10) to secure the writing performance, wherein the casing cylinder (18) is formed of a material that presents low gas permeability or gas impermeability.
摘要:
Ein Schreibgerät, insbesondere ein Kugelschreiber mit einer am vorderen Ende eines Schreiberkörpers (1) vorgesehenen Schreibspitze, mit einem im Schreiberkörper (1) angeordneten, axial verlagerbaren Vorschubkolben (5) und mit zwischen dem Vorschubkolben (5) und der Schreibspitze (2, 3) vorgesehenen Schreibfluid (4), weist am hinteren Ende des Schreiberkörpers (1) eine Gasentwicklungszelle (17) auf, die beim Schließen ihres Stromkreises einen den Vorschubkolben (5) in Richtung auf die Schreibspitze (2, 3) verlagernden Gasdruck erzeugt. Die Gasentwicklungszelle (17) befindet sich in einem gasdichten Raum, dessen vordere Wand zumindest teilweise vom Vorschubkolben (5) gebildet ist und dessen hintere Wand einen durch den erzeugten Gasdruck elastisch verformbaren Wandbereich (10) aufweist. An der der Gasentwicklungszelle (17) zugewandten Seite des Wandbereichs (10) ist ein Kontaktelement (11) vorgesehen, das einen Teil des Stromkreises zwischen der hinteren und der vorderen Fläche der Gasentwicklungszelle (17) bildet.
