BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator capable of performing an application operation while sequentially feeding a solid bar, and more particularly to a mechanism suitable for holding and feeding a solid used as an eyebrow in makeup. And an applicator having:

[0002]

2. Description of the Related Art In general, in a cosmetic or writing instrument, a solid material obtained by solidifying paint in a rod shape is stored in a cylindrical shaft body, and if necessary, the solid material is sequentially fed by a predetermined feeding mechanism. Is known. However, in the case of using such a rod-shaped solid material, the length of the solid material corresponding to the amount of use was stored in the shaft body, so that during use, the outside of the shaft cylinder was In such a case, the feeding mechanism, which is configured to feed a single core, does not perform proper feeding, which causes a decrease in workability in the coating operation. Had occurred. In particular, in the case of eyebrows, etc., since a relatively low elasticity material formed by solidifying a pigment or the like into a rod as a solid material is used, the above-mentioned breakage during use is likely to occur, which makes it difficult to handle. I was

At present, as shown in FIG. 17, a writing tool has been proposed and implemented in which a plurality of divided cores are sequentially fed out in advance. In FIG. 17, an inner tube a having a slit a1 is directly connected to a rotating member b, and an outer tube c having a spiral groove c1 formed on an inner wall thereof is connected to a tip locking member d.
It is directly connected to. The propulsion device f having the projection e is housed in the inner tube a, and the projection e of the propulsion device f is fitted into the slit a1 of the inner tube a. And the inner pipe a is the outer pipe c
And the propulsion device f and the tip stopper d
And the space formed between the cores g1, g
2, g3... Are fitted in the axial direction.

[0004] In the writing instrument having the above-mentioned configuration, at the time of use, the core g1 protruding from the outlet of the tip stopper d is used. Position the core g2 at the tip stop d
The core assembly g is used by being moved forward so as to protrude further. The movement of the core assembly g is performed by rotating the rotating tool b. That is, when the rotating tool b is rotated, the inner pipe a rotates, and the protrusion e of the propulsion device f moves while being restricted by the slit a1 of the inner pipe a and the thread groove c1 on the inner wall of the outer pipe c. As a result, the propulsion device f advances in the inner tube a, and presses the core gn located at the rearmost position to move the core assembly g as a whole. As described above, in the conventional writing instrument, the core to be used for writing is replaced by a short core alone g1, g2, g3,...
Since the core is divided and formed, the core is hardly damaged by an impact from the outside or the like, and the core can always be stably fed.

[0005]

However, in the above-mentioned prior art, the rotating tool b is simply held rotatably with respect to the end of the holding tool h. In this case, it is difficult for the user to recognize the amount of rotation, and it is difficult to perform a fixed amount of rotation. In particular, if the lead is extended excessively, an unused lead will fall off from the tip stopper d, which causes a disadvantage that an expensive lead is wasted.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a solid material feeding container capable of properly and easily feeding solid material without excess or shortage by performing a rotating operation. And

The engaging portion and the engaged portion are elastically engaged with each other, and can be disengaged by rotation of the inner shaft.

According to the present invention having the above structure, by rotating the inner shaft with respect to the main body shaft, the pushing member rotating together with the inner shaft is axially moved along the guide groove by the pressing force of the spiral groove. , And the solid located at the rearmost position is pressed by the forward movement of the pushing member, and the pressing force is transmitted to the solid located at the front, and pushes the solid located at the foremost end forward. As a result, the solid matter is sequentially fed outward from the main body shaft, and in this rotation operation of the inner shaft, the engagement between the engaging portion and the engaged portion of the engagement mechanism in accordance with at least one rotation of the inner shaft. The engagement and disengagement are performed, and at the time of engagement, an engagement sound, an engagement feeling, and the like are obtained. For this reason,
The user can easily recognize the amount of rotation, can prevent the core from being excessively extended or insufficiently extended, and can obtain good operability.

The engaging mechanism includes an elastic piece formed in a cantilevered spring shape by a slit formed in a peripheral surface of the inner cylinder, and an elastic piece protruding outward from one end of the elastic piece. An engaging portion and an engaged portion fixed to the main body shaft and engaged with the engaging portion are provided. One of the engaging portion and the engaged portion is a projection, and the other is a projection. It is conceivable that the groove is configured to be movably fitted to the projection.

Further, if a plurality of helical grooves are formed on the inner surface of the main body shaft and a plurality of fitting projections movably fitted to the respective helical grooves are provided on the pressing portion of the pushing member, The pushing member can be moved smoothly without bias in the shaft. For example, 180
To form two spiral grooves with a phase difference of
If the pressing portion of the pushing member is provided with a pair of fitting projections which are movably fitted to the respective spiral grooves so as to face each other, the pushing member is held at two opposite places,
It can be moved smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 12 are explanatory views of the applicator according to the first embodiment of the present invention. As shown in FIG. 1, the applicator A according to the first embodiment includes a main body shaft 1, a connecting cylinder 2 fixed to a rear end of the main body shaft 1, and a connecting cylinder 2 at a rear end of the connecting cylinder 2. A rotation operation unit 3 rotatably instructed with respect to the connection tube 2, a coating core W1 protruding from a tip of a forward end portion 1a of the main body shaft 1, and inserted into a peripheral surface of the main body shaft 1 when not in use. The external shape is constituted by the cap 4 which is detachably fitted and covers the coating core W1.

The applicator has an internal structure as shown in FIG. As shown in the figure, the main body shaft 1 has a substantially cylindrical shape, and the outer surface of the forward end portion 1a has a tapered shape whose diameter decreases toward the tip. On the inner surface of the main body shaft 1, a large-diameter inner shaft insertion portion 1B and a small-diameter core insertion portion 1A are formed in front of the large-diameter inner shaft insertion portion 1B. 4 and 18 as shown in FIG.
Two spiral grooves 1B1 and 1B2 are engraved with a phase difference of 0 degree.

An inner shaft 5 is rotatably inserted into the inner shaft insertion portion 1B of the main body shaft 1. This inner shaft 5
As shown in FIGS. 6 and 7, a cylindrical portion 51 inserted into the inner shaft insertion portion 1B, and an arc-shaped one end formed in a cantilever spring shape at the rear end of the cylindrical portion 51 are provided. Elastic piece 52
And a rod-like portion 53 protruding from the rear end of the elastic piece 52. A guide groove is formed on the peripheral surface of the cylindrical portion 51 of the inner shaft 5 at intervals of 180 degrees. 2 as
The slits 51a and 51b are formed along the axial direction. The main body shaft 1 of the cylindrical portion 51
Of the main shaft 1
Is rotatably covered by the connecting tube 2 fixed to be inserted into and removed from the connecting tube 2, and is prevented from being pulled out rearward. Further, the rod-shaped portion 53 projects rearward from the connecting tube 2; Here, the rotation operation unit 3 is fixed.

Further, between the connecting cylinder 2 and the inner shaft 5,
An engagement mechanism 50 is provided for engaging the two in a detachable manner. The engagement mechanism 50 includes an engagement protrusion (engagement portion) 52 protruding in the radial direction on the outer periphery of one end of the elastic piece 52.
a and an engagement groove (engaged portion) 2a formed in the inner surface of the main body shaft 1 along the axial direction. The engagement protrusion 5
2a is always in pressure contact with the inner surface of the connection tube 2 by the elastic force of the elastic piece 52, and engages with the engaging groove 2a when it faces the engaging groove 2a.

As shown in FIG. 8, the engagement groove 2a according to the first embodiment has one end face having an inclined surface 2a1.
Since the other end surface is the locking surface 2a2 that coincides with the radial direction, the engaging projection 52a engaged with the engaging groove 2a can be removed from the inclined surface 2a1 side. Withdrawal from the locking surface 2a2 side is impossible. Therefore, in the engagement state between the engagement protrusion 52a and the engagement groove 2a, the inner shaft 5 can rotate in the X direction with respect to the connection cylinder 2, but cannot rotate in the Y direction. The engagement protrusion 52a and the engagement groove 2a constitute a so-called one-way clutch.

On the other hand, a plurality (nine in the figure) of short application cores W1 to W9 are accommodated in the cylindrical portion 51 of the inner shaft 5 along the axial direction. The application core shown here is formed as an eyebrow ink for drawing eyebrows and the like in makeup, and is made by solidifying a predetermined pigment into a column shape, and has relatively high hardness but low elasticity. It has become. In addition, in FIG. 2, W is each of the coating cores W1 to W9.
Are connected via a wick holder H.

Each of the application cores W1 to W9 is covered with a core holder H. As shown in FIGS. 9 and 10, the core holder H has a substantially cylindrical shape, and an annular projection H3 is formed in the middle of its inner surface.
The portion located further behind is the front covering portion H2, and the portion located forward is the rear covering portion H1. The inside diameter of the rear covering portion H1 is smaller than the inside diameter of the front covering portion H2, and the rear portion of the coating core (for example, W2) positioned in front is press-fitted and held in the front covering portion H2. The front part of the application core (for example, W3) is loosely fitted to the part. The length of the front covering portion H2 and the rear covering portion H1 in the axial direction is set to be longer than the length of the coating core in the axial direction. Is designed such that its peripheral surface is completely covered by the core holder H.

Further, the outer diameter of the front covering portion H2 is formed to be slightly smaller than the reduced diameter portion 1A1 having the minimum inner diameter on the inner surface of the forward portion 1A of the main body shaft 1.
The holder H which has reached A is held by the reduced diameter portion 1A1 with an appropriate pressing force. For this reason, even when the forward end portion 1A of the main body shaft 1 is directed downward, the application core inserted into the inner shaft 1 can be prevented from being accidentally dropped due to its own weight or the like.

An extruding member 6 for extruding the application core is inserted inside the inner shaft 5. The pushing member 6 includes a cylindrical pressing portion 61 movably inserted into the inner shaft 5 and a hollow cylindrical portion 62 integrally formed at a rear end of the pressing portion 61. The pressing portion 61 has a small diameter portion 61a and a large diameter portion 61b integrally formed in front and rear. The cylindrical portion 62 formed integrally with the rear end of the large-diameter portion 61b has slits 6a, 6a extending inward from the rear end.
a to form a cantilever spring-like elastic portion 62a.
Are formed, and an elastic piece 62b is formed by the slits 6b, 6b, and the two elastic pieces 62a and 62b are opposed to each other with an angular interval of 180 degrees. The free ends (rear ends) of the elastic portions 62a and 62b are respectively fitted outwardly in the radial direction.
b1 is protrudingly provided.

The small-diameter portion 61a of the pushing portion 61
Is inserted into the front coating portion H2 of the core holder H of the application core (W9 in this case) located at the rearmost end, and the large diameter portion 61b
Abuts against the rear end of the concentric holder H, while the fitting projections 62a1 and 62b1 are inserted into the slits 51a and 51b of the inner shaft 5, and the respective slits 51a and 51b.
The parts protruding outward from b are fitted into the spiral grooves 1B1 and 1B2 of the main body shaft 1.

Next, the operation of the applicator provided with the feeding container having the above configuration will be described. In use, first, the cap 4 is pulled out from the main body shaft 1 and a coating operation is performed using the coating core W1 protruding from the tip of the main body shaft 1. And
When the application core W1 is consumed and becomes unusable, the next application core W2 is fed out to the front of the main body shaft 1. Here, the unusable state of the coating core is a state in which all the parts of the coating core that are exposed in front of the rear covering portion of the core holder H have been consumed.

In the next operation of feeding the coating core W2, the rotary operation part 3 is fixed to the main body shaft 1 in the direction indicated by the arrow X in FIG.
Can be performed by rotating the That is, when the rotation operation unit 3 is rotated in the direction of the arrow X, the inner shaft 5 rotates in the same direction within the main body shaft 1 together therewith. The fitting projections 62a1 and 62b1 of the pushing member 6 are inserted through the slits 51a and 51b of the inner shaft 5,
a, 51b is a spiral groove 1B of the main body shaft 1.
1, 1B2, the pushing member 6 is rotated by the rotation of the inner shaft 5 so that the slits 51a, 51
The end face b is pressed in the rotational direction, and is moved forward along the slit 51a while rotating along the spiral grooves 1B1 and 1B2 by the pressing force.

At this time, the pushing member 6 is moved 1 in the circumferential direction.
Two fitting projections 6 arranged at an angle interval of 80 degrees
Since it is movably held by 2a1 and 62b1,
The inner shaft 5 moves while maintaining a uniform contact state without deviation, and smooth movement is possible. Then, due to the movement of the pushing member 6, the application core W9 at the rearmost position is pressed forward through the core holder H, the application core W9 moves forward, and the application cores W1 to W8 move forward. Go. In this way, after the second coating core W2 is protruded from the tip of the main body shaft 1, the coating core W1 at the foremost end is removed together with the holder H to expose the front end of the coating core W2. The applicator is ready for application again. Hereinafter, the third and subsequent application cores W3 to W9 can be used while being similarly fed.

In the first embodiment, the inner shaft 5 and the connection cylinder 2 are engaged by the engagement mechanism 50,
When the inner shaft 5 is rotated integrally with the rotary operation unit 3, the engagement protrusion 52 a provided on the elastic piece 52 is engaged with the engagement groove provided on the connection cylinder 2 at a rate of one rotation per rotation of the inner shaft 5. 2a, an engagement sound is generated at the time of engagement, and an engagement sensation (click feeling) is transmitted to the user's hand. By counting the number of sensations, the amount of rotation of the rotary operation unit 3 can be clearly recognized. For this reason, if the number of rotations of the rotation operation unit 3 and the amount of movement of the coating core are checked in advance, the engagement sound and the engagement sensation can be estimated even if the protrusion amount of the coating core W is not always visually checked. In other words, the feed amount can be set with high accuracy and easily by a sensible operation, and excellent usability can be obtained.

In the engagement mechanism 50, a so-called one-way clutch is provided in which the connecting cylinder 2 is rotatable only in the X direction and is prevented from rotating in the Y direction. It can be prevented from moving in the direction. For this reason, as shown in FIG. 9, if each application core and the extruding member 6 are arranged without a gap via the holder H, then each application core W and the extruding member 6 are consumed until all the application cores are consumed. There is no gap between them and the device can be used properly. In contrast,
When the rotation operation member 3 is rotatable in the opposite direction,
There is a possibility that the pushing member 6 may move backward, and a space may be generated between the pushing member 6 and each application core W. In this case, there is a risk that the application tool may be immersed inward due to pen pressure during use, or the application core may rattle in the space due to vibration or dropping during carrying, causing damage to the core W or the inner shaft 5. . Although the above-described prior art includes the possibility that such inconvenience occurs, this embodiment can also eliminate the inconvenience.

Further, in this embodiment, a fitting projection 62a which is a fitting portion between the pushing member 6 and the main body shaft 1 is provided.
Since the elastic members 62a and 62b are formed on the elastic portions 62a and 62b, the connecting tube 2 is detached from the main shaft 1, and the rotary operation portion 3 and the inner shaft 5 are simultaneously removed, or the rotary operation portion 3 is detached from the inner shaft 5. After that, only the inner shaft 5 is pulled backward along the axial direction, so that the fitting projections 62b1 and 62b2 abut against the end faces of the spiral grooves 1B1 and 1B2 and bend inward,
Since the inner shaft 5 is removed from the spiral grooves 1B1 and 1B2, the inner shaft 5 can be pulled out from the inner shaft insertion portion 1B of the main body shaft 1. Therefore, after all the application cores are consumed, the inner shaft 2 is forcibly pulled out, and a new inner shaft 5 containing an unused application core is stored.
Can be replaced by inserting at least
Can be reused. For this reason, it is not only economical for consumers, but also excellent in social aspects such as resource saving and environmental friendliness.

In addition, in this embodiment, after the last coating core (W9 in this case) is moved to the use position, the inner shaft 5 is further rotated when the coating core is consumed. The pushing member 6 is provided with the slit 51 of the inner shaft 5.
The elastic projections 62a and 62b abut against the front ends 51a1 and 51b1 of the first and second elastic members 62a and 51b, and are bent inward.
1, 62b1 is automatically detached from the spiral grooves 1B1, 1B2. For this reason, when replacing the used inner shaft 5 with a new inner shaft 5, the used inner shaft 5 is more easily removed from the main body shaft 1 by once pressing the pushing member 6 against the front end as described above. Can be pulled out, making handling easier.

Further, in the pushing member 6 shown here, inclined surfaces 62a2 and 62b2 which are inclined outward from the front to the rear are formed on the front surface of the fitting projections 62a1 and 62b1, and the slits 51a and 51b are formed. The elastic pieces 62a, 62b
Are smoothly bent inward in accordance with the inclination of the inclined surfaces 62a2, 62b2, so that the fitting projections 62a1, 62b1 are pulled out of the spiral grooves 1B1, 1B2 of the main body shaft 1.
Therefore, according to this embodiment, the inner shaft 5 can be more easily pulled out from the inner shaft insertion portion of the main body shaft 1.

In the first embodiment, the two spiral grooves 1B having a phase difference of 180 degrees in the inner shaft 5 are provided.
1, 1B2 is formed and a pair of fitting projections 62a1 and 62b1 of the pushing member 6 are fitted to these, so that the pushing member 6 can be moved stably. It is also possible to form a spiral groove and fit two fitting projections of the pushing member here.
However, in this case, it is necessary to shift the arrangement positions of the two fitting projections forward and backward along the axial direction in accordance with the spiral groove. The number of fitting projections is not necessarily limited to two, but may be one or three or more. The number and arrangement of fitting projections can be appropriately changed as needed.

Further, the fitting projections 62a1 and 62b1 project from elastic pieces 62a and 62b formed on the pushing member 6, respectively.
Although the elastic pieces 62a and 62b can be inserted into and removed from the helical groove by elastic deformation, it is also possible to project the fitting projection on a simple and inexpensive push-out member having no elastic piece. . However, in this case, it is difficult to remove the fitting protrusion from the spiral groove of the main body shaft 1. Therefore, after all the solid matter is consumed, the entire body including the main body shaft 1 is discarded, that is, a so-called disposable. It is desirable to apply to mold type containers.

Next, a second embodiment of the present invention will be described. In the second embodiment, similarly to the first embodiment, the main body shaft 1, the inner shaft 15, the connection shaft, the rotation operation unit 3 and the like are provided, and the application shaft W and the core holder H are provided. Although the number of parts and the appearance are substantially the same as those of the first embodiment, the shape of the inner surface of the main body shaft 1 and the shape of the inner shaft 15 are different from those of the first embodiment. It has become.

That is, instead of the spiral grooves 1B1 and 1B2 formed in the first embodiment, the inner shaft insertion portion 1B of the main body shaft 1 in the second embodiment is replaced by a front end to a rear end. , Two guide grooves 1B3 and 1B4 extending in the axial direction are formed. This guide groove 1B
3, 1B4 are formed at an angular interval of 180 degrees in the circumferential direction.
2a1 and 62b1 each have a cross-sectional shape that can be movably fitted.

The inner shaft 5 is formed with a cylindrical portion 51, an elastic piece 52, a rod-shaped portion 53, and the like. The portion projecting rearward of the main body shaft 1 is the same as that of the first embodiment. It has a similar configuration, but differs in the shape of the part inserted inside the main body shaft 1 in the following point. That is, in the portion 51A of the cylindrical portion 51 which is inserted into the body shaft 1, two spiral grooves 51A1 and 51A2 having phases different from each other by 180 degrees are formed in a slit shape. Fitting protrusions 62a1, 6 of member 6
2b1 is movably inserted. Each of the spiral grooves 51A1, 51b of the fitting projections 62a1, 62b1
The portion protruding outward from A2 is movably inserted into the guide grooves 1B3, 1B4 of the main body shaft 1. The other configuration is the same as that of the first embodiment.

In the second embodiment of the present invention configured as described above, inside the inner shaft 15, a coating core assembly W formed by connecting the coating cores W1 to W9 with a core holder H is provided.
Are inserted, and by rotating the rotary operation member 3, these can be sequentially fed out to the front. That is, when the rotation operation member 3 is rotated, the inner shaft 15 rotates together with the rotation operation member 3, and the end faces of the spiral grooves 51A1 and 51A2 press the pushing member 6 fitted thereto, and the pushing force is applied by the pushing force. Are the guide grooves 1B3, 1 of the main body shaft 1.
It moves forward in the axial direction along B4. Therefore, also in the second embodiment, by rotating the inner shaft 15 together with the rotating operation member 3, the pushing member 6 is moved to the position where the application core W1 is moved.
To W9 are sequentially fed out to the destination.

Moreover, in the second embodiment,
The fitting protrusions 62a1 and 62b1 of the pushing member 6 are
The inner shaft 15 can be pulled out from the main shaft 1 very smoothly by removing the connecting cylinder 2 from the main shaft 1 because the inner tube 15 is fitted to the guide grooves 1B3 and 1B4 extending in the axial direction. Therefore, the removal of the used inner shaft 15 and the mounting of a new inner shaft 15 can be performed very easily, and the exchangeability of the inner shaft 15 is greatly improved. further,
The extruding member 6 has elastic pieces 6 as in the first embodiment.
Since there is no need to form 2a and 62b, the extruded member 6
Can have a simple cylindrical structure, and can be constructed at low cost.

Further, in each of the above-described embodiments, in order to smoothly move the coating cores W1 to W9 within the inner shaft 5.15 without damaging the coating cores, the periphery of each coating core W1 to W9 is controlled. Is covered by the core holder H, but depending on the type of the application core, the core holder is not used,
It is also possible to store each application core in the inner shaft 5.15 in a state where the application cores are brought into contact with each other back and forth, and further, the application core may be covered with a peelable thin film.

The core holder H is shown in FIGS.
In addition to those shown in FIG. 0, those shown in FIGS. 14 and 15 can also be used. The core holder H has a slit Hs on the peripheral surface of the front covering portion H2 and the like in contact with the inner shaft 5.
Is formed, and the core holder H has elasticity. According to this, the core holder H can be lightly pressed against the inner surface of the inner shaft 5 to prevent rattling occurring between the core holder H and the inner shaft 5 and to prevent damage to the application core W due to external vibration or the like. Can be prevented. 14 and 15, the same or corresponding parts as those shown in FIGS. 9 and 10 are denoted by the same reference numerals.

It is also effective to use an inner shaft 25 as shown in FIGS. 16 (a) and 16 (b) as a means for holding the application core W without looseness in the inner shaft. That is, the inner shaft 25 shown here has a cylindrical portion 51, an elastic piece 5 and a portion protruding outward from the main body shaft 1 having the same shape as that of the first embodiment.
2. A pair of holding pieces 25a. 2 having a rod-like portion 53 and being inserted into the main body shaft 1 having an arc-shaped cross-sectional shape are opposed to each other. The holding pieces 25a and 25b have flexibility and are curved so that their central parts protrude in the axial direction as shown in FIG. Therefore, when the application core W is inserted into the inner shaft 25, the core holder H is held between the holding pieces 25a and 25b with an appropriate force. Therefore, according to the inner shaft 25,
The application lead W can be moved together with the lead holder H without play.

The elastic piece 6 in the pushing member 6
2a, 62b, the elastic piece 52 of the engagement mechanism 50, and the holding pieces 25a, 25b of the inner shaft 25, etc., can be made of a metal having a spring property. It is a molded product made of thermoplastic resin such as polypropylene, polyethylene, polyethylene terephthalate, acrylic butadiene styrene, polyacetal, polyamide, polybutylene terephthalate, polycarbonate, etc., and thermosetting resin such as polyurethane, silicone etc. Desirably.

In each of the above embodiments, the engagement mechanism 50 constitutes a one-way clutch.
The rotation of the inner shafts 5, 15, 25 in both directions can be performed by forming inclined surfaces instead of the engagement surfaces of the engagement grooves of the connection cylinder. It is also possible to move the pushing member 6 backward, so that the application core protruding from the forward end 1A of the main body shaft 1 is stored in the main body shaft 1 again. It is also possible to do.

Further, in the engagement mechanism 50, the elastic piece 5
2, the engaging groove 2a is formed in the connecting tube 2. Alternatively, the engaging groove may be formed in the elastic piece 52, and the engaging protrusion may be provided on the inner surface of the connecting tube 2. The number of mating grooves is not necessarily limited to one, but it is also possible to use a plurality of grooves. In the case of a plurality of grooves, it is possible to obtain a plurality of engagement sounds and engagement sensations per one rotation of the inner shaft 5. The rotation operation can be performed with higher precision, and fine adjustment can be performed.

The present invention is also applicable to the feeding of solids other than eyebrows, such as pencil leads, colored pencil leads, erasers, lipsticks, etc., and the present invention is not particularly limited to the above embodiment. .

[0043]

As described above, according to the present invention, by rotating the inner shaft with respect to the main shaft, a plurality of solids can be used while being sequentially fed outward from the main shaft. If the solid material is easily broken, each solid material may be divided in advance to a length that is not easily broken, and the solid material may be used while being sequentially fed outward, and stable application and writing may be performed. Actions can be taken. In addition, in the rotation operation of the inner shaft, the engagement between the engagement portion and the engaged portion is performed at least once for one rotation of the inner shaft, so that the engagement sound and the sense of engagement are counted. Thus, the user can easily and accurately recognize the amount of rotation, and therefore can feed out the solid matter without excess or deficiency.
