The writing instrument shown in FIGS. 1 and 2 has a plug 2 with an air vent hole 3 at the rear end. It has a main body consisting of a cylindrical barrel l that is closed. The barrel is At the front end, it has a counterbore bottomed by a forwardly directed radial shoulder 5. The shoulder part is a disc-shaped washer made of Noricon rubber or a diagram. A sea 1~ is defined for the outer peripheral portion of the elastic member 6 having the shape of . Said washer The shoulder is secured to the shoulder by a sleeve insert 8 that fits snugly into the end of the barrel. Tighten against 5 (: J is cut and held. Circle & 1 (with a trapezoidal end) on both sides. The piston 9 is inserted into the sleeve, thereby slidingly guiding it in the axial direction. The front end defines a writing tip 10 for contacting a material surface, and the inner end defines a writing tip 10 for contacting a material surface. It defines a reduced central surface for contact with the washer 6, etc. Said piste A capillary restrictor 12 extends through an axial hole formed in the tube. and defines a capillary channel 14 for conveying writing fluid to the tip IO in a controlled manner. However, this restrictor protrudes to the rear of the screw line. of the restrictor ? &t’A part is closely surrounded by sleeve 15, and this sleeve As a valve seat for moving the valve part H formed by the inner enon of the isher 6 act. In this way, the restrictor 12 protruding from the rear of the piston 9- The parts with the rib 15 pass through the center hole of the washer, and these parts have a plurality of holes.

The inner end of channel 14 is sealed with t-MI3. using writing utensils In the normal state when not in use, the washer 6 or hole 16 is covered and closed, and the battery is closed. A brush confined within the barrel and confined at the front end by the washer 6 The liquid storage chamber 17 is prevented from communicating with the liquid storage chamber 17. storage chamber The rear end is closed by an ink follower 20 such as a grease plug or an elastic member. This causes the liquid to move backwards along the barrel as it is used, thus , no measures are required to allow air to enter the storage chamber. becomes. In the normal state of the pen, the valve is tightly closed and the storage chamber 1 The liquid inside 7 is protected so that it does not dry out. Furthermore, this writing tool Liquids will flow out of the storage chamber even if splashed or dropped. It is prevented from coming out.

When using a writing instrument and the tip 10 is pressed against a material surface, the piston 9 It is pressed against the elastic washer 6 and pulled into the barrel, and the piston Press on the back end or inner edge area of the washer to bend the washer inward. Washi The elastic strain of the carrier has two important effects. First, the opening of the washer The hole 16 becomes uncovered and the storage chamber 17 and the capillary channel widen. 14, thereby forcing liquid from the storage chamber onto the material. It can be flowed to the tip where it is. Second, the movement of the washer causes the storage The liquid inside the chamber is slightly pressurized, creating a pumping action that rapidly sends the liquid to the tip. be provided. Of course, the force applied to the tip, for example, lifting the tip from the material When the restoring force obtained by the elastic washer is removed by the piston and forward to make sure the valve closes again.

As shown in Figure 2, the washer 6 has a flat disk shape. It is not essential that this elastic member is suitable for opening and closing the valve. The shape required to obtain the bending ↑, Y property, and resistance to retraction of the tip. It may be. In FIGS. 3 and 4, an annular groove 2o is shown as an example. This groove is shown close to the side edge (,!) in the first case. In the case of fr2, it is located close to the inner edge.

Its structure is almost the same as that of the writing instrument described above. washer is held in the barrel by a nose-shaped cone 25 which is attached to the tip (=1) and is The cone has an axial hole that accommodates a cylindrical piston 26. Said piste The fiber bale 27 passes through the inside of the cone, and its free end extends from the tip of the nasal cone. It protrudes and defines the writing tip. The hole 16 in the valve sleeve 15 is the writing point. The fiber rod, piston and valve sleeve are connected by the force applied to the end. 6 and bend the washer 6 as shown in FIG. transports ink from the storage chamber to the rear end of the fiber rod when the It acts like a sea urchin.

7 and 8 have a fibrous tip constructed in accordance with the present invention. Highlight 1 - Writing instrument shown. Similarly, the valve device is shown in FIG. It is essentially the same as that shown in FIG. The washer 6 is closed within the front end of the barrel. It's locked up. A fibrous core 33 is located within the snout, which is axially having a head slidingly guided with respect to the nasal piece by a receiver 34, the free The end protrudes from the snout and has an 11 wide edge for drawing +l + wide lines of writing liquid. It has a defined azalea shape. The rear end of the core is pressed against the central area of the washer 6 the central tube defining the supply channel 14 and the central tube defining the supply channel 14; It is concave to accommodate the surrounding valve sleeve 15. On the writing tip or surface When pressed, the wick 33 is retracted, bending the elastic washer 6 backwards and opening the valve. The storage chamber is then pressurized, thereby causing the liquid to flow through the holes 16 and the supply channel. 14 to the core (ノ■), and flowed along the duct in the core to the tip, It is written down.

FIG. 9 shows an embodiment of the present invention with a removable tip 40. The valve is shown. Similar to the previous embodiment, the barrel 1 has a counterbore and is elastic. Washer 6 is being washed. However, between the washer and the barrel shoulder, vinegar!・Socket part (A41 flange is retained, its shape and function are shown below) explain. The washer is secured by a nose cone 42 with a central hole at the top. held within the barrel. In this hole, an axial capillary duct 44 is provided. The guide 43 is slidably guided. The tip of the rod that protrudes from the nasal cone is the writing tip. In other embodiments, this bar may be defined by another bar located at its end. It may also function to supply ink to the tip structure. The rear end of 43 is stepped. is held in a sleeve 45 having a hole in the washer 6. It has side shoulders that contact the washer around the central opening. Approx. of washer 6 A bottle 46 is installed in the rear end of the sleeve, which extends halfway to the depth. , this pin connects the stem portion that is seeded in the sleeve hole and the enlarged head. have. A spacer pip 4 is provided between the stem and the head in the radial shoulder. 8 (see Figure 1O), and this shoulder and the end of the sleeve facing it A gap defining a radially oriented hole between the surfaces is defined. Furthermore, before The stem of the bottle has longitudinal ribs 49 spaced apart by the outer periphery, and the stem and between the inner surface of the sleeve (indicated by dashed line 50 in Figure 1O) A longitudinal channel is defined to direct the ink through the radial holes into the axial duct of rod 43. supply to The sleeve 45 and the pin are combined to form a valve with the inner circumference of the washer 6. from a storage chamber 17 forming a seat and located immediately after washer 6 in the barrel. They work together to control the flow of ink to the writing tip. The head of the pin is It is cup-shaped.

When the writing tip is pressed against the surface to be written, the rod 43 is slightly pulled. the valve seat formed by the sleeve 45 and the pin 46, and the washer The inner periphery of the is deformed backwards, thereby pressurizing the ink within the storage chamber. The resistance to shaping can be gradually increased. In this way , retraction or sudden stopping of the writing tip is prevented. Shown in Figure 11 In the embodiment shown, a spring element in the form of a leaf spring 55 is provided, which is connected to the pin 4X. 6 It has a rearward extension 57 in which there is a damper that acts as a damper. A porous pad 58 is housed therein. Therefore, the writing tip is retracted and the wax is removed. When the center of the washer is deformed to the rear, it is defined between the pad 58 and the washer. The flow of writing liquid from the sub-chamber 59 to the main chamber 17 behind the pad. is prevented and the initial pressurization of the liquid in the subchamber is strengthened, allowing it to flow through the opened valve. to enhance the flow of this liquid to the writing tip. Liquid pressurization and flow to the tip Can other devices such as valves be used instead of pads to strengthen the You'll understand.

Another difference between the pen shown in FIG. 11 and the pen shown in FIG. This is the point at which a relatively short fiber bar 60 defining the writing tip is attached. . This structure is similar to the supply channel upstream of tip 60, i.e., channel 44. and a larger flow path such as a channel defined between the sleeve 45 and the pin 46. area, allowing effective porting of all liquids to the tip. facilitates pumping action and also dries out the writing liquid in the channel during long periods of non-use This avoids the risk of clogging the channel. Figure 12 and FIG. 13 show a modified pin and sleeve assembly in which a large The hole is well placed. The stem portion of pin 46 is held tightly within the sleeve. two diametrically opposed longitudinal A groove 62 is provided. The front ends of these grooves form grooves 63 extending on the end faces of the pins. a channel 44 passing through the shaft 43, which is also extruded; It communicates with The rear end of the longitudinal groove 62 communicates with a radial groove 64 in the shoulder of the pin. These grooves define a valve hole which is restricted by the washer 6.

The exact shape of the tip and the delivery mechanism to direct the liquid from the valve to the tip are not very important. Therefore, the present invention can be applied to a variety of different types of writing instruments. You know what I mean. Figure 14 shows the pen shown in Figures 9 and 1t. into the sleeve 45 of the roller ball disposed in place of the rod 43. Assembly shown. The ball housing 65 is inside the tubular case 67. It is installed pre-installed with supply +166. The supply rod bottles the writing liquid. It has an axial hole 68 for transmitting to the wheel 69. As shown, the board A small second storage chamber 70 is defined by the ball housing immediately behind the ball. , but this may not be necessary, or if it is, a larger It may be a volume. Figure 15 shows another tip structure for a highlight pen. ing. The shaft 43 has a counterbore at its front end and has a fiber-like tip 7. 2 or a spigot inserted into the counterbore and a chisel-like prism for drawing a wide line. It has an enlarged head with rate edges. Figure 16 shows a simpler structure. is shown, with a pad at the tip of the tip 43 for applying liquid to the surface of the material.
