DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod-shaped decorative material feeding container for accommodating a small-diameter rod-shaped decorative material such as an eyebrow, a lip liner, an eyeliner, and the like.

[0002]

2. Description of the Related Art Conventionally, as a method of producing a small-diameter rod-shaped decorative material such as an eyebrow, a lip liner, and an eyeliner, a method of pouring a liquid material into a decorative material container, an extrusion die (a mold having a sectional shape of the decorative material), or the like has been described. Hole) is known. Among them, in the manufacturing method by pouring, since the rod-shaped decorative material accommodating portion (first cylinder) of the decorative material container becomes the shape of the rod-shaped decorative material, the container shape that can be adopted is limited, for example, a groove cannot be formed here. I will. Further, when a small-diameter rod-shaped decorative material is manufactured by a casting method, the strength may be weak and the material may be broken. For this reason, in general, small-diameter rod-shaped decorative materials are often manufactured by an extrusion die.

[0003] Conventionally, in a stick-shaped decorative material feeding container, a cup-shaped core chuck may be provided as a holder for the stick-shaped decorative material. However, when the rod-shaped decorative material manufactured by the extrusion die is held by such a core chuck, a gap corresponding to the thickness of the core chuck is generated between the rod-shaped decorative material and the inner peripheral surface of the front cylinder. For this reason, the stick-shaped decorative material in the front cylinder cannot receive support from the side. Therefore, in order to prevent the core from breaking, it is necessary to reduce the opening of the front end of the front cylinder so that the rod-shaped decorative material can be supported from the side, or to use a large-diameter rod-shaped decorative material that is difficult to break. Was. Further, a rod-shaped decorative material (molded core) in which only the portion to be attached to the core chuck is formed to have a small diameter can be employed, but this makes the rod-shaped decorative material expensive.

[0004] For example, Japanese Utility Model Laid-Open No. 33919/1988 proposes a stick-shaped cosmetic material feeding container provided with a nail-type core chuck as shown in FIGS.

As shown in the figure, in this stick-shaped cosmetic material feeding container 101, the front cylinder 102 has a constant inner diameter in the axial direction.
Four vertical grooves 104 are formed on the inner peripheral surface. The core chuck 105 at the tip of the push rod 108 is composed of four claw pieces 105a. These four claw pieces 105a engage with the four vertical grooves 104, respectively. The rod-shaped decorative material 103 has a diameter slightly smaller than the inner diameter of the front cylinder 102, and its base end is held by the four claw pieces 105a.

With such a configuration, the stick-shaped decorative material 103
Is always supported in the entire axial direction by the sliding portion 102c (a portion between the vertical grooves 104) on the inner surface of the front cylinder. Therefore, even if the bar-shaped decorative material 103 is bent due to temperature, humidity, and the like, the bent is naturally corrected.

The projection 107 at the base end of the push rod 108 is engaged with the spiral groove 106 on the inner peripheral surface of the container body 109. Thus, when the front cylinder 102 is rotated with respect to the container body 109, the push rod 108 advances and retreats in the axial direction, and the rod-shaped decorative material 103
Moves back and forth from the opening 102a.

[0008]

However, the stick-shaped cosmetic material feeding container 101 shown in FIGS. 16 and 17 has the following disadvantages.

First, in the stick-shaped cosmetic material feeding container 101, an excessive load may be applied to the claw 105a.

[0010] Specifically, at the limit of the push rod 108 being extended, the upper end of the claw 105a is connected to the upper end 10 of the vertical groove 104.
4a. In addition, since the core chuck 105 and the front cylinder 102 are prevented from rotating by the engagement of the claw pieces 105a and the vertical grooves 104, if the front cylinder 102 is further rotated after reaching the extension limit of the feeding, The torque is applied to the claw piece 105a.

Since the nail piece 105a is not so strong, it is easily deformed under such an excessive load. As a result, the nail piece 105a
May be damaged. Further, since the front cylinder 102 is pushed upward by the claw pieces 105a at the extension limit, it may come off from the container body 109 in some cases.

Secondly, in the configuration of the stick-shaped cosmetic material feeding container 101, it is difficult to change the feeding stroke, resulting in an increase in manufacturing cost.

More specifically, the stick-shaped decorative material feeding container is sometimes manufactured as one series of various kinds of stick-shaped decorative materials. In this case, the stick-shaped decorative material has different properties such as hardness depending on its type. Therefore, it is necessary to change the length of the rod-shaped decorative material, the feeding stroke, and the like for each rod-shaped decorative material, such as shortening the rod-shaped decorative material having a small hardness. However, the stick-shaped cosmetic material feeding container 1
In the configuration of No. 01, it is difficult to freely change the feeding stroke and the like, and as a result, it is difficult to unify the shapes of the stick-shaped cosmetic material feeding containers in one series. Further, if the shape of the stick-shaped decorative material feeding container is forcibly unified, a problem such as an increase in the number of parts occurs, and the manufacturing cost of the stick-shaped decorative material feeding container increases.

The present invention has been made in view of such a problem. In a stick-shaped decorative material feeding container for storing a stick-shaped decorative material so as to be able to be fed, first, a nail piece constituting a decorative material holding portion is provided. The object of the present invention is to provide a material that does not require a load, and that can easily change the length and the feeding stroke of the rod-shaped decorative material to be stored secondly, and in this case, change and addition of parts can be minimized. I do.

[0015]

According to a first aspect of the present invention, there is provided a front cylinder for accommodating a rod-shaped cosmetic material so as to be able to advance and retreat, a container body rotatably connected to the front cylinder, and a makeup for holding the rod-shaped cosmetic material. A push rod provided with a material holding portion at its tip, a spiral cylinder which is provided non-rotatably with the container main body and in which the push rod is inserted in a screwed state, and a detent which stops the cosmetic material holding portion and the front cylinder from rotating. In the rod-shaped cosmetic material feeding container provided with a stopping mechanism, a plurality of vertical grooves are formed on the inner surface of the front cylinder, and the cosmetic material holding portion is constituted by a plurality of claw pieces movable in the vertical grooves, By providing a plurality of protrusions on the outer periphery that are screwed into the spiral grooves on the inner surface of the spiral cylinder so as to form a row below the claw pieces, by engaging the protrusions that have come out above the spiral cylinder into the vertical grooves. In addition to constituting the detent mechanism, the spiral is formed near the lower end of the push rod. Comprising a stopper member defining a stroke limit of said push rod by abutting the lower end surface of the.

In a second aspect of the present invention, the width of the claw piece is equal to or less than the width of the protrusion.

[0017] The third invention is to constitute the spiral sleeve with the container body and another body, unit sandwiched between the claws on one side of the push rod through interpolation <br/> this spiral sleeve and said stopper member side Is formed, and this unit is manufactured by assembling the unit with the container main body and the front cylinder.

According to a fourth aspect of the present invention, the length of the vertical groove of the front cylinder is longer than the stroke length of the push rod.

According to a fifth aspect of the present invention, the stopper member is a bend piece formed near a lower end of the push rod.

In a sixth aspect of the present invention, the lower limit of the stroke of the push rod is determined by the lower end of the stopper member abutting the bottom surface of the container body.

According to a seventh aspect of the present invention, a lower limit stopper portion is provided at a portion of the push rod which has come out above the spiral cylinder, and the lower limit stopper portion abuts on the upper end of the spiral cylinder to reduce the stroke lower limit of the push rod. Determined.

In an eighth aspect of the present invention, a plurality of engaging strips are provided below the plurality of claw pieces to be engaged with the vertical grooves, and the lower ends of these engaging strips are connected to the lower limit stopper section. And

According to a ninth aspect of the present invention, the lower limit stopper portion includes a pin which is removably mounted in a pin mounting hole which penetrates the push rod in a lateral direction.

[0024]

According to the first aspect of the present invention, when the container body and the front cylinder are rotated, the protrusion of the push rod advances and retreats along the spiral groove, and the push rod advances and retreats in the axial direction. Thereby, the stick-shaped cosmetic material held by the cosmetic material holding portion (claw piece) at the tip of the push rod is drawn out from the front cylinder or drawn into the front cylinder. In this case, the protrusion that comes out above the spiral cylinder engages with the vertical groove on the inner circumference of the front cylinder and functions as a detent. Further, the push rod is extended to the stroke upper limit when the upper end of the stopper member at the lower end of the push rod comes into contact with the lower end of the spiral cylinder. For this reason, even at the upper limit of the push rod stroke, the claw piece does not receive a load from the vertical direction. In addition, at the upper limit of the push rod stroke, the force for pushing the push rod to the spiral cylinder portion is received by the spiral cylinder itself via the stopper member, so that the front cylinder is pushed in the axial direction and detaches from the container body. It will not be lost. Furthermore, at the upper limit of the push rod stroke, since the protrusions extending over a wide range in the push rod axial direction engage with the vertical grooves, the push rod is not twisted even if the container body and the front cylinder are further rotated.
The nail piece is not deformed by the twist of the push rod.
Therefore, it is possible to effectively prevent a phenomenon in which the nail piece is deformed due to deformation of the claw pieces and the like and the front cylinder comes off when the stick-shaped cosmetic material feeding container is operated.

In the second aspect of the present invention, the width of the claw is set to be equal to or less than the width of the projection, so that the claw does not receive loads from the left and right even if it is in the vertical groove.

In the third aspect of the present invention, since the unit is constituted by the push rod, the spiral cylinder, and the stopper member, the stick-shaped cosmetic material feeding container can be assembled simply by incorporating the unit into the container body and the front cylinder. Therefore, assembling efficiency can be improved and productivity can be increased.

In the fifth aspect, since the stopper member is formed of a bend piece near the lower end of the push rod, the number of parts and the number of assembling steps can be reduced as compared with the case where the stopper member is provided separately from the push rod, and the cost can be reduced. Can be achieved.

In the sixth aspect, the lower limit of the push rod stroke is determined by the lower end of the stopper member coming into contact with the bottom surface of the container body. Therefore, by changing the axial length of the stopper member, the feed stroke length and the lower limit of the stroke are reduced. Can easily be changed. Therefore, it is possible to configure a stick-shaped cosmetic material feeding container that is compatible with stick-shaped decorative materials of various lengths only by replacing the stopper member. Accordingly, it is possible to uniformly mass-produce a series of unified container lengths and the like for various types of stick-shaped decorative materials, and to reduce the cost of container production.

In the seventh to ninth aspects, since the lower limit of the push rod stroke is determined by the lower limit stopper, the position of the lower limit stopper is changed so that the claw piece position at the extension stroke length and the lower limit of the stroke can be changed.
Can be easily changed. Therefore, only by changing the push rod or the position of the lower limit stopper,
It can be adapted to various lengths of bar-shaped decorative material. Therefore, parts can be shared in a series in which the length and the like of the container are unified for various types of rod-shaped decorative materials, and the cost of manufacturing the container can be reduced. In particular, in the eighth invention, if a plurality of pin mounting holes are provided at different positions in the axial direction of the push rod and a pin is mounted in one of the pin mounting holes, the position of the lower limit stopper portion is reduced. Can be easily changed without increasing the number of parts. Further, since it is not necessary to make the stopper member at the lower end of the push rod abut on the bottom surface of the container main body, the bottom of the container main body can be a cylindrical opening.
Therefore, it becomes possible to mount various components in this opening, and it is also easy to integrally mold the spiral cylinder with the container body.

[0030]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 6 show a stick-shaped decorative material container 1 according to an embodiment of the present invention.

As shown in FIG. 1, a stick-shaped cosmetic material feeding container 1
Is composed of a front cylinder 2, a container body 3, a spiral cylinder 9, a push rod 6, a stick-shaped decorative material 5, and the like.

The front cylinder 2 comprises an exposed part 2b and a rotating part 2c. At the upper end of the exposed portion 2b, an opening 2a through which the stick-shaped decorative material 5 advances and retreats is provided. The rotating part 2c is provided in the container body 3
Housed within. In this case, the rotating portion 2c is rotatably attached to the container main body 3 by fitting in a concave and convex manner. Also,
An O-ring 13 is attached to the outer peripheral groove 20 of the rotating portion 2c, and a frictional resistance is given between the rotating portion 2c and the container body 3.

A rod-shaped decorative material 5 such as an eyeliner, a lip liner, or an eyebrow is accommodated inside the front cylinder 2.
The lower end of the stick-shaped decorative material 5 is held by a plurality of claw pieces 4 a of the claw-shaped holding portion 4. The claw-shaped holding section 4 includes a push rod 6
Is formed at the tip. Each claw piece 4a of the claw-shaped holding portion 4 is movable in a vertical groove 8 formed on the inner surface of the front cylinder 2.

The step formed on the inner surface of the container main body 3 serves as the mounting portion 16 of the spiral cylinder 9. The cylindrical spiral tube 9 is housed in the container body 3 and is set on the mounting portion 16. An engagement strip 12 is formed on the outer surface of the spiral cylinder 9. The engaging strip 12 is non-rotatably engaged with a knurl 17 formed on the inner surface of the container body 3. A spiral groove 11 is formed on the inner surface of the spiral cylinder 9.

It is to be noted that by increasing the pitch of the spiral groove 11 (in such a manner as to stand in the axial direction), the spiral cylinder 9
Can be manufactured more efficiently. For example, when the helical cylinder 9 is manufactured by injection molding, it is not necessary to use a complicated screw removal method or the like, and a stripper method or the like is used.
The formed spiral cylinder 9 can be easily rotated and removed from the mold.

As shown in FIGS. 4 and 5, a plurality of projections 7 are formed on the outer periphery of the push rod 6. These projections 7 form a row below each claw piece 4 a above the push rod 6 and are arranged so as to follow a spiral trajectory having the same form as the spiral groove 11. The push rod 6 is housed in the stick-shaped cosmetic material feeding container 1 so as to penetrate the spiral tube 9. Thereby, a part of the plurality of protrusions 7 on the outer periphery of the push rod 6 is screwed and engaged with the spiral groove 11 of the spiral cylinder 9. With such a configuration, when the front cylinder 2 and the container main body 3 are rotated, the push rod 6 and the spiral cylinder 9 rotate, the projection 7 advances along the spiral groove 11, and the push rod 6 is extended. That is, the spiral cylinder 9 (spiral groove 11) and the projection 7 on the outer periphery of the push rod 6 constitute a feeding mechanism.

The projections 7a located above the spiral cylinder 9 among the projections 7 on the outer periphery of the push rod 6 are connected to the vertical grooves 8 in the front cylinder 2.
Engages. As a result, the protrusion 7 a is
The function of stopping rotation. That is, when the projection 7 comes out above the spiral groove 11, it becomes a projection 7a, and the role changes from the component (male screw) of the feeding mechanism to the component of rotation stop.

The width of each of the above-mentioned claw pieces 4a is set to be equal to or smaller than the width of the projection 7 of the push rod 6. Thereby, the pressure from the left and right is received by the projection 7a, and is not applied to the claw piece 4a.

At the lower end of the push rod 6, a stopper member 10 is provided.
Is provided. The stopper member 10 has an annular convex portion 15 formed on the inner surface thereof. The annular convex portion 15 is fitted into an annular concave portion 14 near the lower end of the push rod 6 to thereby provide
It is attached to the lower end of the push rod 6. The stopper member 10 determines the upper and lower limits of the dispensing stroke of the stick-shaped cosmetic material dispensing container 1. That is, as shown in FIG. 6, the upper limit of the feeding stroke is where the push rod 6 advances and the upper end surface 10 a of the stopper member 10 contacts the lower end surface 9 a of the spiral cylinder 9. The lower limit of the dispensing stroke is where the push rod retreats and the lower end 10b of the stopper member 10 contacts the bottom surface 3b of the container body 3.

The length L of the feeding stroke can be easily changed by changing the stopper member 10 without changing other components.

For example, as shown in FIG. 7, by employing a vertically long stopper member 50, the position of the stopper member upper end surface 50a at the lower limit of the feeding stroke is increased, and the feeding stroke length L is reduced. can do.

By providing the annular convex portion 51 of the stopper member 50 at a high position, the push rod 6 can be at a high position at the lower limit of the stroke. Thereby, the stick-shaped decorative material feeding container 1 can be adapted to the short-shaped stick-shaped decorative material 5 while maintaining the same outer shape (total length).

Therefore, according to the present embodiment, the length of the rod-shaped decorative material 5 and the length of the dispensing stroke can be easily changed in the series of the rod-shaped decorative material feeding container 1 having the same outer shape by changing the necessary minimum components. can do.

An O-ring 13 is mounted between the rotating part 2 c of the front cylinder 2 and the container body 3. This O-ring 13
Is caused by the frictional resistance exerted on the rotation of the front cylinder 2 and the container body 3 due to the pressure applied when the stick-shaped decorative material 5 is used (the so-called cup-down) in which the stick-shaped decorative material 5 falls into the stick-shaped decorative material feeding container 1. Can be prevented. This is particularly effective when the spiral groove 11 is designed to stand in the axial direction (therefore, when the push rod 6 easily loses its pressure and retreats). Further, since the O-ring 13 provides an appropriate resistance to the rotation of the front cylinder 2 and the container body 3, it is possible to give the operator a heavy lifting and lowering operation feeling.

In assembling the stick-shaped decorative material feeding container 1, the following assembling method may be adopted in order to improve the assembling efficiency and increase the productivity.

That is, as shown in FIG.
A total of three members, the spiral cylinder 9, the push rod 6, and the stopper member 10, which are manufactured separately from each other, are assembled into a unit. Then, insert this unit into the container body 3,
Assemble.

More specifically, first, the push rod 6 is inserted into the spiral cylinder 9 while the projection 7 on the outer periphery of the push rod 6 is engaged with the spiral groove 11 on the inner surface of the spiral cylinder 9. Then, the annular convex portion 15 of the stopper member 10 is fitted into the annular concave portion 14 near the lower part of the push rod 6, and the unit is assembled.

Subsequently, this unit is inserted into the opening 3a of the container body 3 from the stopper member 10 side.
As a result, the spiral cylinder 9 is placed on the placing portion 16 of the container body 3, and the engaging ridges 12 on the outer periphery of the spiral cylinder 9 are synchronously engaged with the knurls 17 on the inner periphery of the container body 3.

Finally, the front cylinder 2 is fitted to the container body 3 while aligning the positions of the vertical grooves 8 and the claw pieces 4a, and the stick-shaped decorative material feeding container 1 is completed.

Next, the operation will be described.

When using the stick-shaped cosmetic material feeding container 1,
The front cylinder 2 is rotated while supporting the container body 3. In this case, since the front cylinder 2 and the push rod 6 are prevented from rotating by the engagement of the projection 7a of the push rod 6 and the vertical groove 8 of the front cylinder 2, the push rod 6 rotates with respect to the spiral cylinder 9. Therefore, the projection 7 of the push rod 6 screwed into the spiral groove 11 of the spiral cylinder 9 is
And the push rod 6 advances upward. Then, each claw piece 4 a of the claw-shaped holding portion 4 at the tip of the push rod 6 moves upward in the vertical groove 8. Thus, the stick-shaped decorative material 5 held by the claw-shaped holding portion 4 is fed out from the opening 2 a of the front cylinder 2.

The feeding of the stick-shaped decorative material 5 can be performed up to the upper limit of the feeding stroke shown in FIG. At the upper limit of the extension stroke, the upper end surface 10a of the stopper member 10 comes into contact with the lower end surface 9a of the spiral cylinder 9, so that the push rod 6 cannot be extended further upward.

At the upper limit of the extension stroke, most of the projections 7 on the outer periphery of the push rod 6 escape above the helical cylinder 9 and become projections 7a functioning as detents. Therefore, even if the user attempts to rotate the front cylinder 2 and the container body 3 with a stronger force after the feeding stroke reaches the upper limit, the rotational force is increased in the axial direction of the push rod 6. Since the projections 7a can be distributed and received by a large number of projections 7a over the range, the push rod 6 is hardly twisted. Therefore, it is possible to prevent the nail 4a from being damaged or the stick-shaped decorative material 5 being detached from the nail 4a due to the kinking of the push rod 6.

Further, even at the upper limit of the feeding stroke, the front cylinder 2 is not pushed upward. That is,
The force that pushes the push rod 6 upward with respect to the spiral cylinder 9 is received by the spiral cylinder 9 itself via the stopper member 10, so that it does not act on the front cylinder 2 and other members. Therefore, even if the front cylinder 2 and the container body 3 are further rotated at the upper limit of the feeding stroke, the front cylinder 2
Does not come off the container body 3.

On the other hand, in order to store the fed rod-shaped decorative material 5 in the rod-shaped decorative material container 1 again, the container body 3 and the front cylinder 2
Is rotated in a direction opposite to that at the time of feeding. As a result, the feeding mechanism operates in the opposite direction to that described above, and the stick-shaped decorative material 5 retreats downward.

Note that, as shown in FIG.
a and the protrusions 7 are shifted from each other, and the vertical grooves 8 on the inner surface of the front cylinder 2 are separately formed by the vertical grooves 8 with which the protrusions 7a engage and the vertical grooves 8 with which the claw pieces 4a slide. Good. However, as shown in FIG. 2, when one vertical groove 8 has both functions of engaging the projection 7 a and sliding the claw piece 4 a, the width of the claw piece 4 a can be designed to be larger. Since it is possible, it is advantageous in securing a holding area for holding the rod-shaped decorative material 5.

Further, as shown in FIG.
The sliding portion between them may be a knurl sliding portion 60 that is knurled in the axial direction. Thus, the contact area between the knurled sliding portion 60 and the rod-shaped decorative material 5 can be provided to the rod-shaped decorative material 5 from the side by a necessary minimum contact. Thus, the knurl sliding part 60
By reducing the contact area between the rod-shaped decorative material 5 and the rod-shaped decorative material 5 to minimize the phenomenon that the rod-shaped decorative material 5 is scraped by the contact with the sliding portion or receives resistance from the sliding portion during stroke. Can be.

The push rod 6 may be a push rod 6 'shown in FIG. The push bar 6 'has the following two differences as compared with the push bar 6. .

As a first difference, the push bar 6 'is provided with a vent piece 18 integrally formed with the push bar 6' as a stopper instead of the mountable stopper member 10.

The bend piece 18 is formed near the lower end of the push rod 6 ', and its upper end surface 18a contacts the lower end surface 9b of the spiral cylinder 9 at the upper limit of the feeding stroke. Thereby, it functions as a stopper for determining the upper limit of the feeding stroke.

On the other hand, when the spiral cylinder 9 is assembled, the bend piece 18 is inserted into the spiral cylinder 9 from the lower end side.
At this time, the inclined surface below the bend piece 18 is pushed by the inner wall of the spiral cylinder 9, and the bend piece 18 is bent toward the cavity 19.
Thereby, assembling of the push rod 6 'and the spiral cylinder 9 can be performed smoothly. Therefore, when the push rod 6 'is employed, the assembly process of the unit including the push rod 6' and the spiral cylinder 9 can be simplified. However, since it is necessary to form a hollow portion 19 in the push rod 6 'for bending the bend piece 18, the diameter of the push rod 6' is slightly large. For this reason, the use of the push bar 6 'is suitable when the diameter of the stick-shaped decorative material 5 to be used is slightly large.

As a second difference, the projection 7 ′ of the push rod 6 ′ has a shape inclined in the direction along the spiral groove 11 of the spiral cylinder 9. As a result, the width W1 of the projection 7 '
Can be relatively wide. Therefore, the width W2 of the claw piece 4a 'of the claw-shaped holding portion 4' (as described above, this is
The width W1 of the protrusion 7 'of the push rod 6' is equal to or smaller than the width W1), so that the holding area of the stick-shaped decorative material 5 can be increased.

FIG. 11 shows a stick-shaped decorative material feeding container according to another embodiment of the present invention.

This embodiment has the following two differences from the embodiment shown in FIGS. That is, as a first difference, the push rod 6 is provided below the claw piece 4 a of the claw-shaped holding portion 4, in the engagement strip 2 extending in the axial direction.
5 is provided. As a second difference, the spiral cylinder 9 is formed integrally with the container body 3.

More specifically, the engaging strip 25 is formed to have a width equal to or greater than the projection 7.
As in the case of a, it functions as a component of a detent that engages with the vertical groove 8.

Further, by providing the engaging strip 25, the lower end face 25a (lower limit stopper section) of the engaging strip 25 is brought into contact with the upper end face 9a of the spiral cylinder 9 (the portion other than the entrance and exit of the spiral groove 11). The contact point can be set as the lower limit of the stroke of the push rod 6. Therefore, it is not necessary to provide a bottom surface in contact with the lower end of the stopper member 10 in the container body 3, and the lower part of the container body 3 can be opened in a cylindrical shape. Even if the lower end surface 25a of the engagement ridge 25 abuts on the upper end surface 9a of the spiral cylinder 9, the engagement ridge 25 is fixed to the side surface of the push rod 6, so that the claw above the engagement ridge 25 is caught. Piece 4a
Is not deformed.

By providing the opening at the lower part of the container body 3 as described above, the container body 3 integrally provided with the spiral cylinder 9 is provided.
Can be molded.

In the opening at the lower part of the container body 3,
A part 23 such as a tip or a brush can be fitted through the O-ring 22. Further, it is possible to form a knurl portion 21 on the outer periphery of the lower end portion of the container body 3 and to provide a cap 24 to be engaged with and attached to the knurl portion 21 for the convenience of the user.

FIGS. 12 to 15 show still another embodiment of the present invention.

This embodiment differs from the embodiment shown in FIG. 11 in that a pin mounting hole 71 is formed in the push rod 6 and a pin 72 can be mounted in the pin mounting hole 71. doing.

A plurality of pin mounting holes 71 are provided at substantially the center of the projections 7 arranged in the axial direction, and penetrate the push rod 6 laterally. The pin 72 is mounted in any one of the pin mounting holes 71. In this case, an annular convex portion 72 a formed on the outer periphery of the pin 72 is fitted into an annular concave portion 71 a formed on the inner periphery of the pin mounting hole 71, and the pin 72 is fixed to the pin mounting hole 71.

The pin 72 mounted in this way is
It functions as a lower limit stopper that determines the lower limit of the stroke. That is, as shown in FIG. 15, at the lower limit of the stroke of the push rod 6, both ends of the pin 72 abut on the upper end surface 9 a of the spiral cylinder 9 (the portion other than the entrance 11 a of the spiral groove 11) and push the push rod 6 further. Makes it impossible to descend.

Accordingly, the lower limit of the stroke (stroke length) of the push rod 6 can be variously set depending on which of the plurality of pin mounting holes 71 the pin 72 is mounted. In particular,
As the pin mounting hole 71 on the lower side is selected as the pin mounting hole 71 for mounting the pin 72, the push rod 6 at the lower stroke limit is selected.
And the stroke length of the push rod 6 is reduced. When the pin 72 is not mounted in any of the pin mounting holes 71, the lower end surface 25a of the engaging strip 25 is connected to the upper end surface 9 of the spiral cylinder 9, as shown in FIGS.
The position where the contact is made with a is the lower limit of the stroke. Therefore, the feeding stroke can be changed without increasing the number of parts or exchanging parts, and it is possible to easily cope with the rod-shaped decorative materials 5 having different lengths.

In each of the above-described embodiments, the number of rows of the protrusions 7 or the number of the claw pieces 4a are set to be equal to the number of the vertical grooves 8 and the number of the spiral grooves 11, and as described above. Matching the numbers is convenient in assembling and manufacturing.
However, the present invention is not limited to such a form. For example, while there are a plurality of vertical grooves 8 and the like, the number of rows of the projections 7 is one, for example, the number of rows of the projections 7 or the claw pieces 4a. Can be smaller than the number of the vertical grooves 8 and the number of the spiral grooves 11.
