Description

TECHNICAL FIELD The present invention relates to an adapter and a writing instrument capable of widening the width of a liquid to be discharged from a pen-type discharger with a narrow tip.

2. Description of the Related Art Pen-type discharge tools such as correction pens and paste pens have been known as discharge tools for discharging liquid materials such as correction fluid and glue. In such a pen-type dispenser, a liquid material is discharged from a spring-loaded narrow-diameter valve or a spring-loaded ball-point pen tip (see, for example, Patent Documents 1 and 2). Such a pen-type dispenser is effective for application in a fine range because the handwriting becomes thin.

When applying a liquid material over a wide area, such as for correcting a wide area of several characters or more, using the above-described pen-type dispensing tool, it takes time to apply the liquid material, and the thickness of the applied liquid material becomes uneven. . The liquid material needs to be dried, but the liquid material in thick portions is difficult to dry, requiring a long drying time.

For example, if you use a pen-type dispensing tool with a thin tip as a correction pen, after applying correction fluid, if you try to write on it, there will be a thick part that bulges in the center of the correction fluid. can. And, in addition to the fact that it is difficult to write on these thicker areas because the coating film is uneven after drying, only that area dries slowly, so when you rewrite on the area where the correction fluid has been applied, the correction fluid may be difficult to write on. It may involve the part that is not dry and make it dirty instead.

To avoid this, let the modified area dry thoroughly before overwriting, but it takes a long time to dry completely. For this reason, an increasing number of users are using tape-like devices such as correction tapes and glue tapes, instead of pen-type liquid dispensers.

For example, in order to allow the discharge tool to be applied over a wide area, it is conceivable to employ a mechanism in which the tip for discharging the liquid material is shaped like a spatula so as to be able to discharge the liquid material over a wide area. However, with such a mechanism, it is difficult for the discharger to discharge the liquid uniformly, and the wide opening surface often results in too much liquid being discharged. In addition, since the area in contact with air is large, the pen tip tends to dry out, and there is a problem that the long-term storage performance tends to deteriorate.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an adapter and a discharge tool that can apply a wide range of liquids even if they are of pen type.

According to one aspect of the present invention, the adapter comprises: a fixing member fixed to the tip of a pen-type discharger body; a frame attached to the fixing member; a squeegee for spreading the liquid material discharged from the discharge tool, the squeegee being arranged on the fixed member side.

According to one aspect of the present invention, it comprises a pen-type ejector main body that ejects a liquid from its tip, and the adapter described above.

ADVANTAGE OF THE INVENTION According to this invention, even if it is a pen type, it can provide the adapter and discharge tool which can apply|coat the linearly-applied liquid material widely and uniformly.

According to the present invention, by adopting a structure in which an adapter is attached to a pen-type discharger main body, the basic application performance and long-term storage performance of the discharger main body can be maintained as before. The problem of drying and long-term storage performance due to widening the pen tip is solved.

Configurations of the adapter 13 and the discharge tool 1 according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. FIG. 1 is a side view showing the configuration of a discharge tool 1 having an adapter 13 according to one embodiment of the invention. 2 to 4 are diagrams showing the configuration of the distal end portion 21a of the discharger main body 11 of the discharger 1 and the adapter 13. FIGS. 2 and 3 are views showing different side views, and FIG. , which is a plan view.

As shown in FIG. 1, the discharge tool 1 includes, for example, a discharge tool main body 11, a cap 12, and an adapter 13. As shown in FIG. The discharge tool 1 is, for example, a correction pen or glue pen.

The discharge tool main body 11 includes a tubular body 21, a tank 22, a liquid substance 23, and a pen tip 24. - 特許庁

The tubular body 21 accommodates the tank 22 or constitutes the tank 22 and holds the pen tip 24 . The cylindrical body 21 has, for example, a cap 12 detachably attached to its distal end, and a pen tip 24 held at its distal end 21a.

Tank 22 contains liquid 23 . For example, the tank 22 is integral with the tubular body 21 or housed within the tubular body 21 . For example, the tank 22 can be deformed by compressing the cylindrical body 21 to increase the internal pressure.

The liquid substance 23 exerts its function by being applied to paper sheets (paper) and then dried. For example, the liquid substance 23 is correction fluid or glue.

The pen tip 24 is held at the tip 21 a of the cylindrical body 21 . The pen tip 24 includes, for example, a cylindrical body 24a, a spring provided in the cylindrical body 24a, and a ball 24b held by the spring and partially protruding from the tip of the cylindrical body 24a. The pen tip 24 is configured such that when the ball 24b is pressed against the paper sheet, the ball 24b retreats inside from the tip of the cylinder 24a and the liquid 23 can be discharged from the tip of the cylinder 24a.

The cap 12 covers the tip side of the discharge tool body 11 including the pen tip 24 . The cap 12 is detachably formed on the discharge tool main body 11 and protects the pen tip 24 .

The adapter 13 has a fixing member 31 , a frame 32 and a squeegee 33 . The adapter 13 is detachably fixed to the distal end of the discharge tool main body 11 such as the cylindrical body 21 or the pen tip 24 by the fixing member 31 . In this embodiment, an example in which the adapter 13 is fixed to the tip portion 21a of the cylindrical body 21 that holds the pen tip 24 will be described. At least the squeegee 33 of the adapter 13 is made of a water-repellent or oil-repellent material, or the surface thereof is subjected to a water-repellent or oil-repellent surface treatment.

For example, the fixing member 31 is made of a material having solvent resistance to the liquid substance 23, for example. Further, for example, the fixing member 31 is made of a material having water repellency or oil repellency, or the surface thereof is subjected to surface treatment having water repellency or oil repellency. For example, the fixing member 31 may be made of metallic material such as iron or copper, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PBT (polybutylene terephthalate), POM (polyacetal), Teflon (registered trademark). ), or a rubber material such as silicon rubber, fluororubber, or urethane rubber.

The fixing member 31 is configured to be attachable to the distal end portion 21 a of the cylindrical body 21 . For example, the fixing member 31 is formed in a cylindrical shape that can be fitted to the distal end portion 21a. One end of the fixing member 31 has a bottom portion 31b having an opening 31a through which the pen tip 24 can be inserted, for example. The bottom portion 31b abuts on the tip of the tip portion 21a to define the position of the fixing member 31 with respect to the pen tip 24 fixed to the tip portion 21a at a predetermined position.

The frame 32 is attached to the fixing member 31 and holds the squeegee 33 . The frame 32 is made of, for example, a solvent-resistant material with respect to the liquid substance 23 . Further, for example, the frame 32 is made of a water-repellent or oil-repellent material, or the surface thereof is subjected to a water-repellent or oil-repellent surface treatment. For example, the frame 32 is made of a metal material such as iron or copper, a resin material such as PE, PP, PET, PBT, POM, or Teflon, or a rubber material such as silicon rubber, fluororubber, or urethane rubber. . As a specific example, the frame 32 has a pair of arms 32a. One end of the arm 32 a is fixed to the fixing member 31 . The other end of arm 32 a is fixed to squeegee 33 .

For example, the pair of arms 32a are fixed to the fixing member 31 by integral molding. As a specific example, one end of the pair of arms 32 a is fixed to the fixing member 31 at a position radially displaced from the central axis of the fixing member 31 . The other ends of the pair of arms 32a are arranged radially from the central axis of the fixing member 31 and on the opposite side of the pen tip 24 from one end of the pair of arms 32a.

As shown in FIGS. 2 to 4, the pair of arms 32a are fixed by being inclined with respect to the axial direction of the fixing member 31 from one end on the side of the fixing member 31 toward the other end, which is the tip. It is fixed to member 31 . The other end (tip) of the arm 32a is formed in a disk shape whose axial direction is perpendicular to the axial direction of the fixing member 31, and the tip surface is formed with a curved surface.

The squeegee 33 is formed in a shape capable of spreading the liquid material 23 applied to the paper sheet. The squeegee 33 is formed in a shape elongated in one direction. The length of the squeegee 33 is set larger than the width of the tip of the pen tip 24 . For example, the squeegee 33 is formed into a shape that allows the liquid material 23 to spread. In this embodiment, the squeegee 33 will be described using an example formed in a round bar shape.

The squeegee 33 is made of, for example, a solvent-resistant material for the liquid substance 23 . Further, for example, the squeegee 33 is made of a water-repellent or oil-repellent material, or the surface thereof is subjected to a water-repellent or oil-repellent surface treatment. For example, the squeegee 33 is made of a metal material such as iron or copper, a resin material such as PE, PP, PET, PBT, POM, or Teflon, or a rubber material such as silicone rubber, fluororubber, or urethane rubber. .

The squeegee 33 is held at the tips of the pair of arms 32 a contacting paper sheets in a posture in which the axial direction is perpendicular to the axial direction of the fixing member 31 , and is radially adjacent to the pen tip 24 . The squeegee 33 is arranged so as to be shifted toward the fixing member 31 in the axial direction from the tips of the pair of arms 32a. That is, the squeegee 33 is arranged such that a part of the outer peripheral surface along the axial direction faces the paper sheet, and the pair of arms 32a are in contact with the paper sheet with a predetermined gap therebetween. Separate. Thereby, the squeegee 33 spreads the liquid substance 23 applied to the paper sheet to a constant thickness.

The squeegee 33 is set to, for example, 0.1 mm to 2.0 mm, more preferably 0.1 mm to 1.0 mm from the tips of the pair of arms 32a that contact the paper sheet. In addition, the squeegee 33 has a radial distance (interval) from the ball 24b of the pen tip 24 (the tip of the discharge tool), for example, in the range of 0.1 mm to 5.0 mm, more preferably 0.1 to 3 mm. .0 mm range. Also, the length of the squeegee 33 sets the width of the liquid material 23 (handwriting). The length of the squeegee 33 is set to 10.0 mm or less, for example.

For example, when the liquid material 23 is supplied to paper sheets, the discharge tool 1 having the adapter 13 configured in this way presses the pen tip 24 against the paper sheets and moves the ball 24b into the cylindrical body 24a. At the same time, the cylindrical body 21 is pressed to increase the internal pressure of the tank 22 . As a result, the liquid material 23 is supplied from the nib 24 to the paper sheet.

At this time, the longitudinal direction of the squeegee 33 of the adapter 13 is perpendicular to the moving direction of the pen tip 24 on the primary side in the moving direction. In this state, when the pen tip 24 is moved in the direction of applying the liquid material 23 , the squeegee 33 passes the liquid material 23 supplied from the pen tip 24 . The squeegee 33 exists closer to the fixing member 31 than the tips 32b of the pair of arms 32a.

Therefore, since the squeegee 33 passes through the liquid material 23 while being separated from the paper sheet by a certain distance, the liquid material 23 linearly discharged from the pen tip 24 is immediately and uniformly spread on the paper surface, and the liquid material It is possible to widen the object 23 (handwriting) and make the film thickness of the liquid object uniform. In addition, by making the film thickness of the liquid material 23 uniform and eliminating lumpy thick portions on the handwriting film, there are no portions where the drying time is slow, and as a result, the time required for rewriting from above can be shortened. can be done.

Further, since the distal end surfaces of the pair of arms 32a holding the squeegee 33 are formed into curved surfaces, the arms 32a can be stably moved to the paper sheet even if the posture of the discharge tool body 11 is inclined with respect to the surface of the paper sheet. Can abut on foliage. In addition, since the tip of the arm 32a is formed in a disk shape, when the arm 32a contacts the paper sheet, the contact portion (tip) of the arm 32a that contacts the paper sheet and the squeegee 33 are in contact with each other. Since the distance is kept constant, the liquid material 23 can be spread with a stable film thickness.

In addition, the adapter 13 is made of a material having solvent resistance to the liquid 23 so that it is not damaged by the liquid 23 . Therefore, the adapter 13 can be used repeatedly. At least the squeegee 33 of the adapter 13 has water repellency or oil repellency. As a result, the adapter 13 can be easily removed even if the liquid substance adheres. This is because if the liquid adheres to the squeegee 33 after use and solidifies, the adhered liquid may hinder the spread of the applied liquid the next time it is used. Adhesion of the liquid to the adapter 13 is prevented by making it easier to adhere to paper sheets, and by making it easy to remove the liquid by applying vibration or the like even if it solidifies while adhering to the squeegee. This is because, even if it adheres, the adhered liquid substance can be easily removed.

Alternatively, remove the adapter 13 from the tip 21a, or incline the pen tip 24 to such an extent that the pair of frames 32 and squeegee 33 of the adapter 13 do not hit the paper sheets or handwriting (liquid material 23) to remove the liquid material 23. If you eject and move (write), you can make fine corrections as before. For this reason, it is possible to use one discharge tool 1 using the adapter 13 for both thick and thin.

Further, the adapter 13 described above sets the distance between the squeegee 33 and the ball 24b of the pen tip 24, which is the tip of the discharge tool, in the range of 0.1 mm to 5.0 mm, more preferably 0.1 mm to 3.0 mm. Since it is set within the range, it is possible to suitably widen the applied liquid material. This is because if the distance from the pen tip 24 to the squeegee 33 is too wide, the liquid will not spread well.

The length of the adapter 13 is set to 0.1 mm to 2.0 mm, preferably 0.1 mm to 1.0 mm, from the tip of the pair of arms 32a that contacts the paper sheet. Since the width is set to 10.0 mm or less, the liquid material can be preferably spread. This is because the liquid material spreads due to the capillary force acting between the paper sheet and the squeegee 33. If the gap between the paper sheet and the squeegee 33 is too large, the capillary force does not occur and the liquid material does not spread well. Also, if the squeegee 33 is too long, it takes a long time for the liquid to spread, which is impractical.

As described above, according to the adapter 13 and the discharge tool 1 according to the embodiment of the present invention, the liquid material 23 can be widely applied even with a pen type.

In addition, this invention is not limited to embodiment mentioned above. For example, in the above example, the squeegee 33 has a round bar shape, but is not limited to this. The squeegee 33 may have a plate shape, a coil shape, or a brush shape. That is, the squeegee 33 can be appropriately set as long as it can spread the ejected liquid material 23 and make the film thickness constant.

In the above example, the frame 32 has a pair of arms 32a. However, the frame 32 is not limited to this. .

Further, although the fixing member 31 described above has a configuration having the bottom portion 31b, the configuration is not limited to this, and the fixing member 31 may have a configuration without the bottom portion 31b. In addition, the fixing member 31 may be configured to fit the distal end portion 21a with a relatively hard resin material, or may be configured to fit the distal end portion 21a with an elastically deformable material such as a rubber tube. good too.

Moreover, in the above-described example, examples of a correction pen and a glue pen for discharging correction fluid and paste as the liquid substance 23 have been described as the discharge tool 1 provided with the adapter 13, but the discharge tool 1 is not limited to this. That is, the adapter 13 can be appropriately used as long as it is configured to be used at the tip of a discharge tool that discharges the liquid material 23 from the tip.

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the scope of the invention. Further, each embodiment may be implemented in combination as appropriate, in which case the combined effect can be obtained. Furthermore, various inventions are included in the above embodiments, and various inventions can be extracted by combinations selected from a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiments, if the problem can be solved and effects can be obtained, the configuration with the constituent elements deleted can be extracted as an invention.
