[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a correction fluid applicator with a valve mechanism, which is used for concealing characters, lines, patterns, etc. written on a paper surface by applying a correction fluid.

[0002]

[Prior art and its problems]

 In general, in a correction fluid applicator with a valve mechanism, a coating destination member having an outflow hole at the tip and having an inner periphery near the outflow hole as a valve seat is fitted in the opening of the container containing the correction fluid. Then, the coating shaft is loaded in the coating destination member such that the tip of the coating shaft projects from the outflow port, and the valve portion provided on the coating shaft is pressed against the valve seat by the biasing force of the spring member. By pressing the tip of the coating shaft against the correction site on the paper surface, the coating shaft retracts and opens the valve, and the correction fluid in the container passes through the gap between the coating shaft and the inner peripheral surface of the coating destination member, It is constructed so that it flows out from the outflow hole onto the paper surface.

Conventionally, the coating tip of such a correction fluid applicator has a thin round shaft shape or a conical shape having an outer diameter of the tip of about 1 to 2 mm, and small letters or a part thereof, or complicated drawings. It is suitable for erasing and correcting small parts such as patterns and patterns. However, when erasing a wide range, such as correction of multiple characters or line-by-line correction of a document, the conventional applicator needs to be reciprocated many times or spread at the application destination, which is very troublesome. , The correction film is thick and tends to have uneven unevenness, and when writing correction characters etc. on the surface of the coating film, the waiting time for drying the coating film becomes long and the writing on the surface of the coating film causes unevenness. However, there is a problem that the efficiency of calibration and the like is significantly reduced.

[0004]

[Means for Solving the Problems]

 In view of the above situation, the present invention can be used as a correction fluid applicator with a valve mechanism, which can be freely used for thin coating and thick coating according to the size of the correction area, and the usage is very operationally difficult. It is also an object of the present invention to provide a correction coating which is easy to apply and is thin and smooth in thick coating.

In order to achieve the above-mentioned object, the correction fluid applicator according to claim 1 of the present invention allows the correction fluid to flow out through a valve mechanism from an outflow hole of an application tip portion provided at one end side of the correction fluid container. And a cylindrical thick coating tip that can be externally fitted to and removed from the application tip portion, and the valve shaft loaded inside the application tip portion has a tip end portion. The tip end face of the thick coating tip is formed to be wide and protrudes from the outlet hole and is urged by a spring force in the direction of sealing the outlet hole. In this state, the tip end portion of the valve shaft is set to project from the wide tip end surface when mounted on the portion.

According to a second aspect of the present invention, in the correction fluid applicator according to the first aspect, the wide tip surface of the thick coating tip is inclined with respect to the plane orthogonal to the tip axis. Is adopted.

According to a third aspect of the present invention, the correction fluid applicator according to the first or second aspect employs a configuration in which the tip of the thick coating tip has a fluid reservoir recess.

[0008]

[Action]

 When the correction liquid applicator according to the present invention is used for ordinary correction by thin coating, the main body of the applicator may be used as it is in the conventional manner without mounting a thick coating tip on the main body. That is, by pressing the tip of the valve shaft protruding from the outflow hole of the applicator body against the repaired part of the paper, the valve shaft retracts and opens the valve, and the correction fluid in the container is discharged from the outflow hole. It flows out and is applied to the paper surface with the width of the application destination around the outflow hole.

On the other hand, for example, when a wide range of erasure such as correction of a plurality of characters or line-by-line correction of a document is to be performed, a thick coating tip is attached to the coating tip portion of the applicator body, and the wide tip of the tip is applied. The surface may be pressed against the corrected portion of the paper and the applicator may be moved in a direction orthogonal to the width direction. That is, when the tip of the tip for thick coating is pressed against the paper surface, the tip of the valve shaft protruding from the tip retreats to open the valve, but the correction fluid flowing out from the outlet hole is used for thick coating. Since the entire tip surface of the chip is spread, a strip-shaped correction coating film is formed with the width of this tip surface. This modified coating film is uniform, thin, and smooth, dries quickly, and correction characters can be easily and neatly written in a short waiting time.

If the tip end face of the thick coating tip is set to be inclined with respect to the plane orthogonal to the tip axis, the applicator is similar to a writing instrument when a wide width application is performed using the tip. Moreover, since the application can be performed while being inclined with respect to the paper surface, the operability of application is good. If the tip of the thick coating tip is provided with a liquid reservoir recess, even if the pressing force against the paper surface is weakened during coating or the coating speed increases and the amount of correction fluid is temporarily insufficient, Since the correction liquid that has accumulated in the recesses is applied, stable thick coating correction can be performed without causing the coating film to fade.

The tip end surface of the thick coating tip has a longitudinal width L (see FIG. 2) of 4.0 to 7. It is preferable that the tilt angle θ (see FIG. 2) with respect to the plane orthogonal to the chip axis is set to about 0 mm and about 20 to 40 degrees, respectively. In the closed state, the height of the tip of the valve shaft protruding from the tip of the thick coating tip is preferably about 0.5 to 2.0 mm.

【Example】

 FIG. 1 shows a correction fluid applicator according to an embodiment of the present invention. This applicator comprises an applicator main body 10 with a valve mechanism in which a front cylinder 2 made of a hard synthetic resin is externally fitted and screwed into an opening 1a of a container 1 made of an elastic synthetic resin material such as a polyamide resin, A thick synthetic resin chip 20 made of a hard synthetic resin, which is fitted to the coating tip portion 2a formed on the tip side of the tip cylinder 2, is provided, and a white pigment such as titanium oxide is provided in the applicator body 10. A correction solution (not shown) that is dispersed and contained at a high concentration is stored.

The tip cylinder 2 of the applicator main body 10 has a small-diameter coating tip portion 2a having a tip-side half portion having a conical shape, and a large-diameter intermediate cylinder portion 2b having a tip-side half portion having a truncated cone shape. It is composed of a threaded cylindrical portion 2b having a larger diameter and an internal thread 3b corresponding to the external thread 3a on the container 1 side is engraved, and has an outflow hole 4 at the tip of the application tip 2a and the application tip 2a. An annular convex portion 5 is formed on the outer periphery of the base portion side, and locking projections 6a, 6a are provided on both sides in the radial direction of a step portion 6 formed between the coating tip portion 2a and the intermediate tubular portion 2b.

Reference numeral 7 denotes a valve shaft made of a hard synthetic resin, which is loaded inside the coating tip portion 2a of the tip cylinder 2, and has a tapered front portion 7a, a large-diameter round shaft-shaped intermediate portion 7b, and a thin portion. The protrusion 9 provided at the tip of the front portion 7a is attached to the outflow hole of the front cylinder 2 by the elastic force of the coil spring 8 which is composed of the rear portion 7c having a round shape and is pressed against the rear end step portion of the intermediate portion 7b. The valve portion 11a, which projects outward from the nozzle 4 and is provided around the base of the protrusion 9, is pressed against a valve seat 11b provided on the inner inner circumference of the outflow hole 4 of the tip cylinder 2.

Reference numeral 12 is a spring receiving member made of a semi-hard synthetic resin having an upper part of a double cylinder shape, and an inner cylinder part 12b is integrally formed on an inner upper part of the outer cylinder part 12a. The coil spring 8 is locked by the inward flange 12c, and the flange 12d provided on the outer circumference of the outer cylinder 12a is provided between the end surface of the opening 1a of the container 1 and the inner peripheral step 13 of the front cylinder 2. It is set so as to fix itself, and at the same time, to perform the function of a packing that seals between the container 1 and the front tube 2.

As shown in FIGS. 2 to 4, the thick-coating tip 20 has U-shaped notches 21 and 21 on both sides in the lower end of a cylindrical lower portion 20a in the radial direction, and an upper portion 20b has a lower portion 20a. It is formed into a flat shape in which the meat portion of the following cylinder is cut off diagonally from both sides, and the upper end face (tip face) 22 has a longitudinal width L (see FIG. 2) of about 4.0 to 7.0 mm. It has a wide rectangular shape and is inclined at an angle θ of about 20 to 40 degrees with respect to the plane F orthogonal to the chip axis (see FIG. 2). A central portion along the longitudinal direction of the upper end surface 22 forms a flat bottom liquid storage recess 22b by providing bimodal raised portions 22a, 22a on both edges of the long side. Further, the inside of the tip 20 is shaped to fit properly on the outer periphery of the coating tip portion 2a of the applicator body 10, the lower portion forms a circular hole 23a, and the inner periphery thereof has an annular locking groove 24. The upper part connected to the circular hole 23a is a tapered conical hole 23b which is opened in the center of the liquid reservoir recess 22b.

The thick coating tip 20 is configured such that the notches 21 and 21 are fitted to the locking protrusions 6a and 6a with respect to the coating tip portion 2a of the applicator body 10 as shown in FIGS. By forcibly fitting the outer ring, the ring-shaped locking groove 24 and the ring-shaped convex portion 5 of the front cylinder 2 are fitted to each other, so that the ring-shaped locking groove 24 can be mounted in a state where the ring-shaped locking groove 24 does not relatively rotate and does not drop out. Thus, in this mounted state, as shown in FIG. 1, the entire inner circumference of the tip 20 is in close contact with the outer circumference of the application tip portion 2a and the valve shaft 7 protruding from the outflow hole 4 of the application tip portion 2a. The protrusion 9 is set so as to protrude from the upper end surface 22 of the tip 20 by about 0.5 to 2.0 mm.

When the correction solution applicator having the above-mentioned configuration is used to perform ordinary fine coating, it is sufficient to use only the applicator body 10 without mounting the thick coating tip 20. The operation is the same as that of the conventional correction fluid applicator with a valve mechanism. If the protrusion 9 of the valve shaft 7 protruding from the outflow hole 4 is pressed against the correction site on the paper surface, the valve shaft 7 retracts. Since the valve is opened and the correction liquid in the container 1 can flow out from the outflow hole 4, if this pressing state is required, by moving the main body 10 while adding the squeezing action by the pressing of the container 1, this outflow A correction coating film is linearly formed on the paper surface with the width of the coating destination around the hole 4 (usually about 0.5 to 2.0 mm).

On the other hand, when a wide range of erasing such as correction of a plurality of characters or line-by-line correction of a document is performed, a thick coating tip 20 is attached to the coating tip portion 2a of the applicator body 10, and the wide tip 20 is widened. The tip end surface 22 of the is pressed against the corrected portion of the paper surface, and the applicator may be moved in the direction orthogonal to the width direction. By this pressing, the protrusion 9 of the valve shaft 7 protruding from the front end face 22 retreats and opens the valve, but the correction fluid flowing out from the outflow hole 4 spreads to the entire front end face 22. A strip-shaped correction coating is formed with a width of 22. The correction coating film is uniform, thin, and smooth, dries quickly, and correction characters can be easily and neatly written in a short waiting time.

The correction fluid applicator of the present invention is not limited to the structure of the above-mentioned embodiment, but the shape and material of the container and the application destination part, and the shape and arrangement configuration of each part of the valve mechanism including the valve shaft. In addition to the embodiments, various design changes can be made to the detailed structure such as a locking structure for preventing the thick coating tip from rotating with respect to the coating tip portion and preventing it from falling off, and the tip end face and the overall shape of the tip.
