As disclosed in JP-12095, the cap compressed on the tip end fitting when not in use is attached to or detached from the tip end fitting to send the air compressed in the cap into the liquid tank. Accordingly, there is known an applicator configured to pressurize the inside of the liquid tank to push out and supply the correction liquid to the liquid application port of the tip end device. However, in the case of this conventional applicator, the paragraph number (0
012) to page 6, paragraph number (0013), in the process of applying the cap to the tip end fitting, the inner cylinder in the cap is brought into close contact with the outside of the tip end fitting. The inside of the inner cylinder is a sealed space that prevents air leakage, and from there, the cap is pushed to the area where the tip fitting is completely covered, thereby compressing the air inside the inner cylinder.
By using the compressed air to move the spherical coating body that is in contact with the inner surface of the rim of the liquid coating port backwards against the elastic force (spring force) of the spring so as to separate from the liquid coating port, A gap is created between the edge of the liquid application port and the spherical applicator, and air is sent from the gap into the liquid tank through the tip mouthpiece, thereby pressurizing the inside of the liquid tank and utilizing that pressure to apply the liquid. The correction liquid in the tank is pushed out to the liquid application port in which the spherical applicator of the tip end fitting is provided and supplied (supplemented) to the application port.

い。However, in the case of the above-mentioned applicator, air is sent into the liquid tank by performing the operation of attaching the cap to the tip mouthpiece once or several times during use. Since the internal pressure is increased, if the correction fluid does not come out from the solution application port while applying the correction fluid to the erroneous part, the application of the correction fluid is temporarily interrupted. Then, the cap must be attached to the tip fitting to raise the internal pressure in the liquid tank.

Further, in order to improve the sealing property of the cap with respect to the tip mouthpiece, the cap is fitted so tightly and tightly with respect to the tip mouthpiece that the capping operation requires a considerable force. Therefore, the operation is very difficult for a child, a relatively weak woman, and the like, and the handling property is poor.

Turning the tail plug 2 in either the clockwise or counterclockwise direction from the state of FIG. 1 and the solid line state of FIG. , The convex edge 18 of the liquid tank 3 which is elastically engaged with the chevron edge 17
The sliding engagement is made from the valley engaging portion 17-1 to the apex engaging portion 17-2. In other words, the peak locking portion of the chevron edge 17 with respect to the convex piece 18
Rotate tail plug 2 so that 17-2 faces each other. Then, the convex piece
With the rotation of the tail plug 2 in which the apex locking portion 17-2 faces the apex 18, the protruding piece 18 is continuously provided from the valley locking portion 17-1 to the apex locking portion 17-2. By causing the liquid tank 3 to move forward against the spring 6 in the process of sliding 3 and the convex piece 18 to engage with the apex locking portion 17-2 (the state of the chain double-dashed line in FIG. 5), The liquid tank 3 is automatically held at its forward limit. As a result, the compressed state of the elastic portion 5 that is compressed as the liquid tank 3 advances is maintained (see FIG. 2). On the other hand, when the tail plug 2 is rotated again in the same direction or in the opposite direction after the application work is completed, the convex piece 18 moves from the apex locking portion 17-2 of the chevron edge 17 to the valley locking portion 17-1 side. And the sloping edge of the tail plug 2 connected with it
By sliding 17-3, the holding state of the liquid tank 3 is automatically released, the liquid tank 3 is retracted to the rear of the barrel 1 by the spring 6, and the elastic portion 5 of the liquid tank 3 is moved.
Is also returned to the stretched state before deformation.

The internal pressure of the tank 3 is increased. And the internal pressure is tail plug 2
The correction liquid M is applied to the erroneous portion because it is kept continuously unless the valley locking portion 17-1 of the chevron edge 17 is returned to face the convex piece 18 of the liquid tank 3 by the rotation of. While the work is continued, the stable supply (replenishment) of the correction liquid M to the liquid application port 4a can be continuously performed. On the other hand, after the use, the engagement of the convex piece 18 with the apex locking portion 17-2 of the chevron edge 17 is automatically released by the above-described usage, and the liquid tank 3 is retracted by the spring 6 from the forward limit to the initial retreat. Returned to the limit. As a result, the inside of the liquid tank 3 can be returned to the initial normal pressure state before the internal pressure is applied, so that the correction liquid M does not inadvertently flow out from the liquid application port 4a.

る良好で大変便利な塗布具となる。Since the applicator of the present invention is constructed as described above, it has the following operational effects. ． According to claim 1, when the tail plug at the rear end of the barrel is rotated, the convex piece of the liquid tank is slidably displaced from the valley locking portion of the mountain edge of the tail plug end toward the apex locking portion. Since the convex piece of the liquid tank slides from the valley locking part to the apex locking part, the liquid tank moves to the front of the barrel against the spring. Then, the deformed state of the elastic portion that is compressed in the cylinder direction or expanded toward the inside of the cylinder is maintained. On the other hand, when the tail plug is rotated again,
The convex piece engaged and received by the apex locking portion of the chevron edge is disengaged from the apex locking portion, and the rotation direction of the tail plug is caused by rotation of the tail plug and backward movement of the liquid tank by the spring toward the rear of the barrel. The elastic portion of the liquid tank is returned to the initial state before it is deformed because it is slid toward the valley locking portion existing in the (circumferential direction) and is returned to the valley locking portion again. Therefore, according to the applicator of the present invention, the internal pressure of the liquid tank in which the correction fluid is loaded can be increased by the operation of turning the tail plug at the rear end of the barrel, and the increase in the internal pressure can be achieved unless the tail plug is turned again. Since it can be continued, the correction fluid does not deteriorate during the work of applying the correction fluid to the erroneous portion as in the past, and the internal pressure is increased continuously while the coating operation is continued. Thus, the correction liquid can be stably supplied (supplemented) to the liquid application port of the tip end fitting. Moreover, since the internal pressure can be returned to the initial normal pressure state after use, there is no fear that the correction liquid will accidentally come out such as spillage from the liquid application port. In addition, the internal pressure can be raised or returned to the initial normal pressure state by repeating a simple rotation operation such as turning the tail plug, so that operation can be performed easily and handling is excellent. It is a very convenient applicator.

According to claim 2, when the tail plug at the rear end of the barrel is rotated in the forward or reverse direction, the rotation of the tail plug is transmitted to the mover, and the mover is screwed with the guide projection on the inner surface of the barrel. By jointing, the shaft is rotated forward toward the front of the cylinder to advance the liquid tank against the spring to compress the elastic part of the liquid tank in the cylinder direction or to bulge it toward the inside of the cylinder and deform the elastic part. Hold the state. On the other hand, when the tail plug is rotated in the opposite direction to the above-mentioned rotation direction, the mover is rotated and retracted to return to the initial position in the tail plug, and the spring is retracted toward the rear of the barrel of the liquid tank to cause elasticity. The part is returned to its original condition before it was deformed. Therefore, the same effect as described above can be obtained. In addition, it is possible to freely change the amount of forward movement of the mover that accompanies the rotation by operating the rotation of the tail plug in stages, so the compression state of the elastic part of the liquid tank can be freely changed. You can That is, the degree of increase in the internal pressure of the liquid tank can be freely changed according to the remaining amount of the correction liquid.
