[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid applicator used for applying a liquid such as a correction liquid, ink, an adhesive or a sealant to a paper surface or the like via a valve mechanism.

[0002]

2. Description of the Related Art Generally, this type of liquid agent applicator is
The liquid agent outlet has a taper-shaped end on the liquid agent container,
The cone-shaped valve body is arranged such that its tip portion projects outwardly from the outlet and the outlet is normally sealed by the biasing force of the spring. By pressing the valve body against the surface to be coated, the valve element is pushed in, and the liquid agent in the container flows out from the annular opening of the outlet and is applied to the surface to be coated.

In addition, such a liquid agent applicator is provided with a cap to be fitted on the application destination side in order to protect the application destination and prevent contamination with the liquid agent. However, in the conventional case, it is necessary to remove this cap after each application and refit it after application, and in particular, if the liquid agent is a correction liquid for concealing erasure used for correcting characters on a document, etc. Since each application is small and frequently used repeatedly, there is a problem that it is very troublesome to attach and detach the cap, and the removed cap is likely to drop or be lost from the desk or the like.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention has been made in view of the above-mentioned circumstances and allows the coating operation to be carried out without any trouble while the cap is always fitted to the applicator body, and therefore there is no risk of the cap falling or being lost, and moreover, the cap. It is an object of the present invention to provide a liquid agent applicator capable of extremely easily switching between the original protective posture and the coating posture by one-touch operation.

In order to achieve the above object, a liquid agent applicator according to a first aspect of the present invention is an applicator having a taper-shaped one end of a liquid agent container to which a liquid agent is drawn out through a valve mechanism. A guide groove in a spiral direction, which is composed of a main body and a cap fitted on the application destination side of the applicator main body, and is set on the outer peripheral surface of the applicator main body in a length not more than 1/4 turn of the applicator main body. And a locking portion continuously provided at both ends of the guide groove, the cap has an opening at the tip, and a projection that fits in the guide groove is provided on the inner peripheral surface of the cap. A finger hook portion is provided on the end side, and the coating tip moves in and out from the opening by axial movement of the cap with respect to the applicator body as the cap rotates, and the projection is engaged with the locking portion at the rotation limit position. Locks the cap and applicator body. Those that are configured so that.

According to a second aspect of the present invention, the engaging portion in the liquid applicator according to the first aspect is extended from the end of the guide groove in the circumferential direction of the applicator body and is more than the guide groove. It adopts a structure consisting of shallow locking recesses.

[0007]

In the liquid agent applicator of the first aspect, since the projection on the inner peripheral surface of the cap is fitted in the guide groove in the spiral direction formed on the outer peripheral surface of the applicator body, the cap is rotated by rotating the cap. The cap axially moves with respect to the applicator body within the length range of the guide groove. Therefore, if the application tip is located inside the cap at one end of this moving stroke and the application tip is projected outward from the opening at the tip of the cap at the other end, the application can be performed by simply twisting the cap. It is possible to convert the tip to the coatable state that comes out of the opening and the coatable state that fits inside the cap, and it is not necessary to remove the cap during coating. Then, at the rotation limit position of the cap, the projection of the cap engages with the locking portion of the outer peripheral surface of the applicator body to lock the cap and the applicator body, so that the cap can be applied as described above. The cap can be stably held in both the uncoated state and the non-applied state, and it is possible to avoid a situation where the downward movement of the cap during the application causes a trouble or the application destination is exposed due to an inadvertent movement when the cap is not used.

Moreover, the guide groove is 1/100 of the main body of the applicator.
Since the length is set to 4 laps or less, the amount of twisting of the cap required for conversion between the coatable state and the coatable state is small, and the finger hook portion is provided on the base end side of the cap. With only one hand holding the body of the device, the finger hook of the cap can be hooked with the index finger or the like to perform a very simple twisting operation.

The spiral direction of the guide groove is a direction which obliquely intersects the circumferential direction of the outer peripheral surface of the applicator body,
The extension may form a helix around the axis of the body.

According to the second aspect of the present invention, since the engaging portion of the applicator main body is formed of the shallow engaging concave portion, the projection rides on the engaging concave portion at the limit position of the rotation of the cap, and the cap and the applicator are mounted on the riding portion. The cap is pressed against the main body, and the cap and applicator main body are locked by the frictional force due to the pressing so that relative rotation does not occur inadvertently, and the locking recess is applied from the end of the guide groove. Since it extends in the circumferential direction of the container body, it does not act as a force to rotate the cap even if a force to push and pull in the axial direction is applied between the cap and the applicator body.

1 shows a pen-type correction fluid applicator according to an embodiment of the present invention. This applicator includes an applicator main body 1 that forms a long tubular container by externally screwing a tapered front barrel 1b into an opening of a container barrel 1a made of a synthetic resin elastic material such as a polyamide resin, and the like. A cap 2 made of synthetic resin fitted so as to cover the whole of the tip cylinder 1b, and a correction liquid 3 containing a high concentration white pigment such as titanium oxide dispersed in the applicator body 1 and a stirring rod. 4 is accommodated and the front cylinder 1
The tip of b is supplied with the correction fluid 3 from the outlet 5 through the valve mechanism.
To form a coating destination 10 for outflow coating.

This valve mechanism has a lead-out port 5 in the front cylinder 1b.
A substantially cone-shaped valve body 6 for opening and closing is loaded with the tip 6a of the valve body 6 projecting outward from the lead-out port 5 and is normally closed by the elastic force of the coil spring 7. By pressing the protrusion 6a against the paper surface with the application destination 10 facing downward, the valve body 6 is pushed in to open the valve. Reference numeral 8 denotes an inner cylinder member, which is held by sandwiching the outer peripheral flange portion 8a between the fitting portions of the container cylinder 1a and the front cylinder 1b, functions as a packing that seals the fitting portion, and the upper side is a coil. It forms a spring bearing for the spring 7.

As shown in FIGS. 2 and 3, four guide grooves 11 in the same spiral direction are equally formed on the peripheral surface of the front cylinder 1a on the base end side where the maximum outer diameter is obtained. Thus, each of the guide grooves 11 is set to have a length over a range of about 1/8 turn (45 degrees) of the front cylinder 1a. At both ends of each guide groove 11, locking recesses 12 a, 1 shallower than the guide groove 11 are provided.
2b are continuously provided in the circumferential direction, and further each locking recess 1 on the application side
A shallower fitting groove 13 is continuous with 2a and extends toward the application destination side in the axial direction.

On the other hand, as shown in FIG. 4, the cap 2 is
The outer shape is a taper-shaped, substantially bullet-shaped, and has an opening 2a having a diameter through which the application tip 10 of the applicator body 1 can enter and exit at the tip, and a pair of U-shapes having a size such that a fingertip is fitted at the base end side. The notches 14 and 14 are formed at positions on both sides in the radial direction, and the finger rests 15 and 15 are formed by the remaining portions of the notches 14 and 14. Then, the inside of the base side of the cap 2 becomes a straight hole 2b having an inner diameter slightly larger than the outer shape of the tip barrel 1b of the application destination body 1, and the guide grooves 11 are formed on the inner peripheral surface thereof.
Are provided with four protrusions 16 having a diameter and a height suitable for fitting.

The cap 2 is a tip cylinder 1 of the applicator body 1.
With respect to a, each protrusion 16 is press-fitted using the material elasticity in a posture that fits into the fitting groove 13, and each protrusion 16 is fitted into the fitting groove 1
By fitting in the locking recess 12a deeper than 3, the fitting state is such that the applicator main body 1 cannot be easily pulled out. Then, the application tip 10 is accommodated inside the cap 2 at the position where each projection 16 is fitted in the locking recess 12a, and the application tip 10 is the opening 2a of the cap 2 at the position where it is also fitted in the locking recess 12b. The axial length S (see FIG. 2) of the guide groove 11 in the front cylinder 1b is set so as to project outward from the.

When the correction liquid applicator is not used, the projection 16 is locked by the projection 12 as shown by the solid line in FIG.
If the position is such that it is fitted to a, the coating destination 10 is the cap 2
Since it is accommodated inside, the tip 4a of the valve body 4 does not have a risk of opening the valve by touching an external article, and the correction fluid 3 attached to the application destination 10 does not stain clothes or the surroundings. Further, in the cap 2 at this position, each projection 16 having a height corresponding to the depth of the guide groove 11 is press-fitted into the shallow locking recess 12a to tighten the front cylinder 1a from the outer peripheral direction 4. From the above, it is stably held at that position, and carelessly rotates or the applicator body 1
It does not come off.

When applying the correction liquid 3, the operator holds the applicator with one hand and hangs the finger of the one hand on the finger hooking piece 15 of the cap 2 until the cap 2 is stopped ( With the right hand, it should be turned clockwise when viewed from the user.
As a result, the protrusions 16 disengage from the locking recess 12a and enter the guide groove 11, and the cap 2 is guided by the guide groove 11 to move axially with respect to the applicator body 1, that is, to the right in FIG. The coating tip 10 projects from the opening 2a, and each projection 16 rides on the shallow locking recess 12b at the end of twisting.
The a is tightened from the outer periphery 4 direction, and becomes stable. Thus, when the coating tip 10 projects, the protrusion 6a is pressed to the position to be corrected on the paper surface to open the valve body 6 in the same manner as a normal coating device, and the U-shaped notches 14 and 14 are normally positioned. The container cylinder 1a may be sandwiched between the thumb and the index finger applied to, and the correction liquid 3 may be drawn out and applied by squeezing it.

After concealing and erasing the required characters and the like by this application, the cap 2 is twisted until it stops in the direction opposite to the above direction, so that the application destination is set inside the cap 2 again and is not used. It will return to the state of. In the twisting operation of the cap 2 before and after the application,
At the end, there is a response when the projection 16 rides on the locking recess 12b or 12a, so that the user can easily confirm that the cap 2 is in the locking position.

In this invention, the detailed configuration, such as the number of guide grooves provided on the applicator main body side, the length, the spiral angle, the structure of the locking portions continuously provided at both ends thereof, the structure of the valve mechanism, etc., is described above. Various design changes are possible other than the embodiment. For example, a recess having the same depth may be provided at both ends of the guide groove, and a locking portion having a ridge-like height that divides the recess and the guide groove may be formed. Further, the finger hook portion on the base end side of the cap may be provided at least at one place, and the shape thereof is not limited to the projecting piece shape as in the embodiment, but may be formed by a projection or a ridge on the outer peripheral surface of the cap. . However, it goes without saying that the present invention can be applied to applicators for other liquid agents such as inks, adhesives, and sealants, in addition to the correction fluids illustrated.
