2. Description of the Related Art A front cylinder is rotatably connected to a container body, a slide groove is provided in the front cylinder, and a claw is provided at a tip of a push rod to form a cosmetic material holding portion. The invention in which the sliding groove is engaged with the sliding groove of the cylinder is disclosed in Japanese Utility Model Laid-Open No. 60-3391.
No. 9 has been published. The purpose of this invention is to form the entire container thinly, and because the distance between the inner wall surface of the core tube and the decorative material is small, the decorative material is reliably protected against external impact without bending inside the core tube. It is designed to do so.

As a method for solving the above-mentioned object, FIG.
A sliding groove 303 is provided in the through hole 302 of the core cylinder 301 shown in FIG. 4 to form a female screw 306 in the outer cylinder 305.

According to this invention, the entire container described above is finished to a small diameter. Further, it is a very excellent invention for the purpose of minimizing the distance between the decorative material and the inner wall surface of the container in the core tube. However, the smaller the diameter of the cosmetic material, the more secure the holding of the cosmetic material holding portion and the core chuck in the stick-shaped cosmetic material feeding container. For example, in the case of lipsticks having a relatively large diameter, for example, the base of the lipstick is held by forcibly inserting the base portion of the lipstick into a cup-shaped core chuck, and the length of the core chuck is reduced to 1/3 to 1/4 of the total length. It is fixed inside and used. However, eyebrow and eyeliner have a core diameter of 2
mm to 3 mm (length is about 25 mm to 35 mm),
The cosmetic material holding portion for holding such a small-diameter cosmetic material core has a length of about 1/5 to 1/6 of the entire length fixed in the core chuck. Japanese Utility Model Application Laid-Open No. 33919/1985 is characterized in that the core of the decorative material is held by a nail, and the nail is just a rectangular plastic plate.

For the above reasons, when actually used,
As a point that the punch body and the nail piece may be deformed by the load. The claw piece itself is used as a rotation stopping mechanism. Counter-twisting load at the lower limit and the upper limit of the claw piece (the user tries to rotate with a force to rotate more at the upper limit, and there is no guarantee that the reverse rotation is not performed at the lower limit). Absent. The protrusion 313 at the rear end of the punch body 312 in FIG.
The distance up to the stroke is the stroke.
3, the small diameter punch body 312 is kinked by a strong force at the ascending limit.

A stick-shaped cosmetic material feeding container in which a push rod having a material holding portion is inserted thereinto to advance and retreat the stick-shaped cosmetic material by rotating the front cylinder and the container body, wherein the front cylinder has a long axis and a short axis. A through hole similar to this rod-shaped decorative material core, in which the material core is slidable, is provided, and a sliding groove facing the long axis is formed in the short axis side in the front cylinder. A nail material at the tip is located, the cosmetic material holding portion holds the rod-shaped cosmetic material by the nail piece, and a screw portion is provided in the axial direction of the push rod, and the screw portion is screwed to the container body. A screwing mechanism unit that engages, and a rotation stopping means for rotating the push rod synchronously on the front cylinder side is provided. To have.

In the second invention, a sliding contact portion is provided on at least one of the outer peripheral surface of each of the claws positioned in the sliding groove of the front cylinder or the sliding contact surface of the sliding groove. At least when the bar-shaped decorative material is held between the nail pieces, each of the nail pieces is always in contact with the sliding contact surface via the sliding contact portion.

In a third aspect of the present invention, a stopper portion is provided at a rear portion of the push rod, and an upper end surface of the stopper portion comes into contact with a lower end surface of a screwing mechanism portion in the container main body, so that a lifting limit is provided. Is determined, and the sliding groove of the front cylinder is set longer than the extending stroke of the push rod.

In a fourth aspect of the present invention, a stick-shaped decorative material having a long axis and a short axis is held at the tip of the push rod by a claw piece located in a sliding groove of the front cylinder facing the long axis. A portion is formed, and in the axial direction on the same row of the claw pieces, engagement projections are provided in a row, and the engagement projections are engaged with a screwing mechanism in the container body, and The retraction limit is determined by the lower end surface of the stopper portion at the rear portion of the push rod abutting on the bottom surface of the container body, and the row-shaped engaging projections formed on the push rod are engaged with the sliding grooves on the front cylinder side. .

In the fifth invention, a cosmetic material holding portion for holding a rod-shaped decorative material having a long axis and a short axis with a claw positioned in a sliding groove of the front cylinder is formed at a tip of the push rod. At the same time, engaging projections are provided at both ends of the long axis of the push rod, and the engaging projections engage with a screwing mechanism in the container body, and move in the through hole on the front cylinder side. I decided to do it.

According to a sixth aspect of the present invention, a relay portion is provided below the claw piece at the tip of the push rod, and when the relay portion engages with the through hole, the front cylinder and the push rod rotate synchronously. Means. In the seventh invention, the width of the engaging strip formed on the relay portion is equal to the width of the engaging protrusion provided in the axial direction of the push rod.

[0013]

According to the first aspect of the present invention, the cosmetic material formed at the tip of the push rod inserted by the rotation of the front cylinder and the container body. The rod-shaped decorative material held by the holding portion is moved forward and backward.

A threaded portion is formed in a rod shaft portion of the push rod extending from the cosmetic material holding portion, and the threaded portion is engaged with a threading mechanism provided in the front portion of the container body. By
A feeding mechanism is configured.

The front cylinder is provided with a through-hole having a similar cross section through which a non-circular rod-shaped decorative material core having a long axis and a short axis can slide, and the surface of this through-hole faces the long axis. A sliding groove is formed on the short axis side. Also, the cosmetic material holding portion is constituted by a plurality of claw pieces formed at the tip of the push rod, and the claw pieces are positioned in the sliding grooves and slide, so that the rod-shaped cosmetic material core is held on the short axis side. It becomes possible to hold it most efficiently mechanically.

Further, since the claw piece and the sliding groove of the present invention are located on the short axis side of the front cylinder, the configuration of the long axis side of the front cylinder is only the thickness of the front cylinder and the core diameter of the rod-shaped decorative material. Since there is no interposition of the claw pieces and the sliding grooves in which the claw pieces slide, it is possible to use a rod-shaped decorative material core having the longest long axis with respect to the long axis side outer shape of the front cylinder. It becomes possible.

In the second invention, the outer peripheral surface of each claw piece forming the cosmetic material holding portion, which is provided on the short axis side facing the long axis located in the sliding groove of the front cylinder, or the sliding surface A sliding contact portion is provided on at least one of the sliding contact surfaces of the groove, and when the stick-shaped decorative material is supported between at least the claw pieces, the claw piece is connected to the sliding contact portion via the contact portion. Since the surface is always in contact with the surface, the dimension between the nail pieces does not become larger than the planned dimension for holding the rod-shaped decorative material, and the nail is reliably held and slid.

In the third aspect of the present invention, a stopper portion is provided at a rear portion of the push bar, and an upper end surface of the stopper portion and a rear end surface of a screwing mechanism portion forming a screwing mechanism of a front portion of the container body come into contact with each other. Thus, the push-up limit of the push rod is determined. Furthermore, the sliding groove formed in the front cylinder is set to be longer than the above-mentioned stroke of the push rod, and thereby, the cosmetic material holding portion is formed even at the limit of raising the rod-shaped cosmetic material core. The claw piece does not abut on the tip of the sliding groove and is not deformed.

In the fourth aspect of the present invention, a holding portion is formed by providing a claw piece on the short axis side of a similar cross section for holding a rod-shaped decorative material core having a long axis and a short axis at the tip of the push rod. The piece makes the sliding groove of the front cylinder slidable.

An engagement projection is provided in the axial direction on the same row as the claw piece, and this engages with a spiral groove formed in a spiral body in the container body and at the same time passes through the spiral groove. The engagement protrusion engages with the sliding groove in the front cylinder to constitute a rotation stopping function. In addition, the lower end surface of the stopper portion at the rear portion of the push rod abuts on the bottom surface of the container body to limit the retraction, so that the rotation stop function is formed in a state in which a part of the engagement protrusion always comes out of the spiral groove. In other words, the row-shaped projections function as a feeding mechanism in the spiral groove in the container main body, and when the spiral groove is screwed into and pulled out, it engages with the sliding groove in the front cylinder in a non-rotatable manner. In other words, it serves as a rotation stopper in the front cylinder. For this reason, it is possible to prevent the kinking of the push rod having a small diameter from reaching the entire rod axis.

In the fifth aspect of the present invention, a cosmetic material holding portion for holding a rod-shaped decorative material core having a long axis and a short axis is formed by providing a claw piece on the short axis side at the tip of the push rod. The engagement projections are provided in a row in both end directions of the shaft. The projection engages with a spiral groove formed in a screwing mechanism in the container body, and moves through the through hole in the front cylinder after passing through the spiral groove.

In order to hold a highly oblate rod-shaped decorative material core having a long axis set to be extremely long and a short axis set to be short,
Inevitably, the width of the claw pieces arranged on the short axis side becomes wide. However, providing the engaging projections on the same row as the claw pieces cannot be formed dimensionally if the flatness is high. Therefore, engaging projections are formed at both ends on the long axis side, and the sliding grooves slide only with the claw pieces,
The push rod is slid while engaging with the through hole, thereby preventing an unnecessary load from being applied to the claw pieces, and performing stable sliding holding even with a rod-shaped decorative material core having an extremely long major axis.
In other words, in the case of a cosmetic material core having a long axis and a short axis that are close to a circle, the engaging strip at the lower portion of the claw formed on the relay portion is made larger in the circumferential direction than the width of the claw and used for rotation prevention. In the case of a decorative material core that is long in the major axis direction and has a high oblateness, the shape of the relay portion itself can be used as a rotation stopper.

According to a sixth aspect of the present invention, the relay portion at the lower portion of the claw at the tip of the push rod is non-rotatably engaged with the through hole of the front cylinder and slides to provide rotation stopping means. Since the right and left pressures that cause kinking are not applied to the claw pieces at the time of sliding, stable holding can be performed.

According to a seventh aspect of the present invention, in the invention according to the fourth aspect, the width of the engaging strip on the relay portion disposed at the lower portion of the claw is provided on the rod shaft portion of the push rod at the lower portion of the relay portion. It is characterized in that it has the same width as the engaging projection provided. As the push rod advances, the projections that have completed the threaded engagement with the helical body successively engage and slide in the sliding grooves, but the engagement strips and the engagement projections have the same width. Therefore, the engagement protrusion also advances while playing the role of a rotation stop.

Therefore, not only the engaging ridges but also the engaging projections engage with the sliding grooves in the front cylinder as a rotation stopper when moving forward and backward, so that the rod shaft portion corresponds to the stroke of the push rod. Has the same result as the rotation stop is formed, and the entire push rod is not twisted.

A relay portion 33 is provided below the nail piece 31. In FIG. 1, the relay portion 33 has an elliptical shape similar to the elliptical core material A. In addition, this relay section 33 includes a claw piece 3.
1 is provided, the width of which is slightly larger than the width of the claw piece 31, and is engaged with the sliding groove 12 in the front cylinder 10. It serves as a rotation stop. At this time, the relationship between the claw piece 31 and the engaging strip portion 34 is good if an excessive load from the lateral direction during rotation is not applied to the claw piece.

A rod shaft 38 extends in the axial direction below the relay portion 33, and a single male screw portion 35 is provided on the surface thereof.
A bend piece 45 as a stopper part 40 protrudes from the rear part of the push rod. The abutment between the upper end surface 47 of the bend piece 45 and the lower end surface 57 of the spiral groove 56 determines the lifting limit.

When the front cylinder 10 and the container main body 20 of the rod-shaped cosmetic material feeding container 1 configured as described above are rotated, the push rod 30 engaged with the spiral groove 56 on the container main body 20 side is formed. The screw portion 35 functions as a feeding mechanism. On the side of the front cylinder 10, the engaging strip 34 provided on the lower relay portion 33 of the claw 31 of the push rod 30 engages with the sliding groove 12 of the front cylinder 10 to stop rotation. Since the function works, the push rod 30 rises while rotating in synchronization with the front cylinder 10, so that the elliptical core material A becomes the first cylinder 1.
0 Projection starts from the opening hole 11 at the tip.

When further rotated, as described above, the push rod 3
0 Upper end surface 47 of the bend piece 45 of the rear stopper portion 40
And the contact with the lower end surface 57 of the spiral groove 56 constitutes a lifting limit.

When the front cylinder 10 and the container main body 20 are rotated in the opposite directions, the push rod 30 starts to retreat by the above-mentioned feeding mechanism, and the lower end surface 37 of the relay portion 33 and the upper end surface 59 of the spiral groove 56 in the container main body 20 come into contact with each other. With this, the push rod 30 is retracted.

The characteristic of the stick-shaped decorative material feeding container of the present embodiment is as follows.
The through hole 14 including the opening hole 11 of the front cylinder 10 is
The elliptical core material A is securely held by the pair of claw pieces 31 located in the sliding groove 12 while always being supported in the axial direction by the inner diameter of the front cylinder 10 because the sliding is possible with the minimum interval. .

A sliding protrusion 32 is provided on the rear surface of the pair of claw pieces 31. When the elliptical rod-shaped decorative material core A is inserted between the claw pieces 31, the sliding protrusion 32 is The holding dimension between the claw pieces 31 is maintained at the planned dimension by abutting on the sliding surface of.

In the present embodiment, a sliding projection is provided on the rear surface of the claw piece 31 to form a sliding contact portion. Conversely, a convex ridge is provided on the inner peripheral surface of the sliding groove 12 of the front cylinder 10 to form a claw. The sliding protrusion 32 may always be in contact with the sliding surface in any case.

The length of the sliding groove 12 of the front cylinder 10 is made longer than the moving stroke of the push rod 30 to prevent the claw piece 31 from abutting on the tip of the sliding groove 12 and to further prevent rotation. Is performed by the engaging strip 34 of the relay section 33 below the claw piece 31. Since the width of the engaging strip 34 is made larger than the width of the claw piece 31, the claw piece 31 is Only plays the role of holding and sliding, and is not involved in the feeding and rotation stopping function.

The first embodiment of the present invention also has the following features. 2 are a rod shaft 38 and a screw portion 35.
The outer diameter of the screw portion 35 is the through hole 1 provided in the front cylinder 10.
If the diameter is not smaller than 4, the push rod 30 is
Since it is impossible to move inside the rod 4, the rod shaft 38 of the push rod 30 has a small diameter. Therefore, the elliptical core material A is a rod-shaped decorative material feeding container suitable for an elliptical core material having a slightly larger cross-section or a larger dimension on the minor axis side and having a shape close to a perfect circle.

Further, since the push rod 30 is often made of a plastic manufactured by injection molding, the push rod is manufactured by a split mold, so that the thread portion has a gentle pitch. The undercut prevents the split mold from coming off.) Therefore, it is suitable for an elliptical core material having a gentle feeding stroke.

Further, since the screw on the surface of the rod shaft 38 of the push rod 30 is a continuous screw portion 35, it is replaced with a spiral groove 56 in the container main body 20, and a screwing mechanism by a simple projection engaging with the screw portion 35. Department.

A method of assembling the stick-shaped decorative material feeding container 1 according to the first embodiment of the present invention will be described with reference to FIG.
In the spiral groove 56 in the screwing mechanism 50 in the front part of the container body 20,
The rod shaft 38 of the push rod 30 is inserted from the rear bend piece 45, and the screw portion 35 of the push rod 30 is screwed into the spiral groove 56. The push rod 30 is attached to the upper end face 59 of the screwing mechanism 50.

Next, a description will be given of a stick-shaped decorative material feeding container 101 according to a second embodiment of the present invention shown in FIGS.

FIG. 4 is a partial longitudinal sectional view of the second embodiment, in which the long axis is viewed from the lateral direction (short axis side). FIG. 5 is an AA sectional view of FIG. 6 is a cross-sectional view taken along line BB of FIG. 4, showing the holding portion 139 of the core material A.
0 shows a rod shaft 138 and an engagement projection 135 instead of a screw. FIG. 7 is a partial vertical cross-sectional view of the push rod 130 as viewed from the lateral direction (long axis side) of the short axis, and the push bar 130 is at the upper limit. FIG.

Hereinafter, the stick-shaped decorative material feeding container 101 of the second embodiment will be described with reference to the accompanying drawings. The rod-shaped cosmetic material feeding container 101 is screwed into a front cylinder 110 and a bottomed container body 120 rotatably connected thereto, a push rod 130 inserted therein, and an engagement projection 135 arranged in the axial direction of the push rod 130. It is composed of a spiral member 150 and a stopper member 140 that engage with each other, and an O-ring 3 that slides between the front cylinder 110 and the container body 120.

The difference between the stick-shaped decorative material feeding container 1 in FIG. 1 and the stick-shaped decorative material feeding container 101 of the second embodiment in FIG. 4 is that a spiral member 150 is provided separately instead of the screwing mechanism 50. That is, the engagement projection 135 is employed as a substitute for the screw portion 35 of the push rod. The difference between the stick-shaped decorative material feeding container 1 and the stick-shaped decorative material feeding container 101 due to the above two differences will be described in detail below.

As shown in FIG. 4, the stick-shaped decorative material B is
The tail portion is firmly held by the cosmetic material holding portion 139 formed by the claw pieces 131 at the 30 tip. The claw piece 131 is located in the sliding groove 112 in the front cylinder 110, and holds the rod-shaped cosmetic material A in a form facing the long axis 115 on the short axis 113 side of the rod-shaped cosmetic material B. An engagement portion 134 is formed below the row of the claws 131, and is engaged with the sliding groove 112 of the front cylinder 110. Below the row of the engaging strips 134, there are engaging projections 135.
And the width 134L of the engagement strip 134 and the engagement protrusion 1
The width 135L of 35 is designed to be the same size, and is engaged with the sliding groove 112 of the front cylinder 110 in FIG.

An engaging projection 135 is further provided on the rod shaft 138 of the push rod 130 up to a stopper member 140 provided at the rear of the push rod 130, and is mounted on the step portion 129 of the container main body 120. The screw mechanism 156 is provided with a means for rotating in synchronization with the screw 120, and is engaged with a spiral groove 156 in the spiral member 150 to constitute a feeding mechanism.

The feature of the second embodiment resides in that the contact between the rear end surface 146 of the stopper member 140 provided at the rear part of the push rod 130 and the bottom surface of the container body 120 serves as a limit for the retraction of the push rod.

Therefore, as shown by the push rod 130 in FIG. 8, the engaging projection 135 of the push rod 130 which is screwed into the spiral member 150 is not engaged with the engaging projection 135b which has passed through the spiral member 150. Engagement projection 13
5a, it can be seen that the engagement protrusion 135b is engaged with the sliding groove 112 of the front cylinder 110 and functions as a rotation stopping function.

The stopper member 140 of the push rod 130
Rear end face 146 or push rod rear end 136 and container body 1
By setting the retreat limit by contacting the bottom 126 of the front cylinder 20, the engaging projection 135 is used as the engaging projection 135 b.
It is possible to always engage in the ten sliding grooves 112.

In the sectional view of the relay 133 shown in FIG.
The dashed circle represents the rod shaft 138 of the push rod 130 that can pass through the through hole 114 of the front cylinder 110, and the engagement protrusion 135b engaged with the slide groove 112 is indicated by the same dashed line.

FIG. 7 is a partial longitudinal sectional view showing a state in which the upper end surface 147 of the stopper member 140 attached to the push rod 130 and the lower end surface 157 of the spiral member 150 come into contact with each other at the limit of the upward movement. When the push rod 130 is viewed from the shaft side, a state is shown in which the engagement protrusion 135 is engaged with the slide groove 112 in the front cylinder 110 to become the engagement protrusion 135b.

In the second embodiment, the width of the engaging strip 134 provided on the push rod 130 and the width of the following engaging projection 135 are equal to each other and are set to 134L = 135L. This means that both the engaging strip 134 and the engaging projection 135 are used as a rotation stopping function. However, the width 134L of the engaging strip does not become larger than the width 135L of the engaging projection.

The feature of this embodiment is that the left and right and up and down loads are not applied to the nail pieces 131 constituting the decorative material holding portion.

One feature of the second embodiment is to provide a feeding container that can be used safely even with a small-diameter rod-shaped cosmetic material core. Since the engaging projections 135b of the push rod 130 are all engaged with the sliding groove 112 on the front cylinder side of the spiral member 150, the claw pieces 131 can stably hold the stick-shaped decorative material B against left and right twists. .

In the first embodiment shown in FIG. 1, the rod shaft 38 of the push rod 30 must be thin because the outer shape of the screw portion 35 passes through the through hole 14 of the front cylinder 10 (FIG. 2).
Also, since the rotation stopper is also the engaging ridge 34 of the relay portion 33 of the push rod 30, the structure is not suitable for a small-diameter core material, whereas the second embodiment has a small-diameter long. It is characterized by being able to perform reasonable sliding on a fragile rod-shaped cosmetic material core having a short axis.

In this embodiment, the spiral member 150 is
The helical pitch is slightly coarse because it is manufactured as a plastic molded product by a stripper method without screw removal in order to improve productivity.

The O-ring 3 installed in the concave groove 116 of the front cylinder 110 is interposed between the front cylinder 110 and the container main body 120 and acts as a resistance at the time of rotation. This prevents the push rod 130 engaged with the cup from going down. Therefore, without the O-ring 3, the push rod 13
A value of 0 causes the cup-down phenomenon due to the pressure applied by the stick-shaped decorative material A to make up.

The assembly and operation are in accordance with the first embodiment.

Next, a third embodiment of the present invention will be described with reference to FIGS. The rod-shaped decorative material core C of the third embodiment has an elliptical shape with a high oblateness that is long in the long axis 215 direction and short in the short axis 213 direction.

This is because, according to the feature of the present invention in which the decorative material core is held by providing a nail piece on the short axis side, the rod-shaped decorative material core has the longest dimension in the major axis direction with respect to the cross section of the front cylinder. A rod-shaped decorative material core having a shaft and a short axis can be efficiently interpolated.

The rod-shaped decorative material core C of the third embodiment is set as an elliptical core that is long in the long axis direction, but is not limited to this form, and may be a rhombus or rectangle long in the long axis direction.

The engagement protrusion 235 on the rod shaft 238 of the spiral groove 256
The threading engagement with the member constitutes a feeding function.

In the present embodiment, unlike the first and second embodiments, the relay portion 233 is used as a rotation stopping function. However, in the case of a rod-shaped decorative material core long on the long axis side, the relay portion 233 is used. There is no problem even if the shape itself is used as a rotation stopping function.

In this case, the sliding groove 212 has no role in the feeding action and the rotation stopping action only by forming a track through which the claw piece 231 passes.

In the present embodiment, the retreat limit is determined by the relay unit 233.
And the front end surface 259 of the screwing mechanism 250a at the front end of the container body 220.

The feature of the stick-shaped decorative material feeding container of this embodiment is as follows.
The engaging protrusions 23 are provided in both directions of the long axis of the rod shaft 238 of the push rod 230.
5 are formed, and as shown in FIG.
Is designed to move in the through hole 214 as it is fed out. Thus, the small-diameter irregular core is held by the decorative material holding portion 239 formed by the claw pieces 231, and the claw pieces 231 can slide without applying a load in operation.

Further, if the engaging protrusion 235 is engaged with the through hole, the engaging protrusion 235 of the push rod 230 can be rotated even if it is further rotated at the raising limit and a rotational force is applied.
By engaging with 4, the torsion of the push rod 230 can be prevented.

In the third embodiment, the engagement protrusion on the push rod makes the rotation stop function also on the front cylinder side, similar to FIG. 4 in the second embodiment. It is virtually impossible to provide a mating projection and engage it with the sliding groove on the front cylinder side. Explaining this, first, since the rod-shaped decorative material core C is long on the long axis side, the claw piece 231 for holding it is inevitably wide in width.

In this embodiment, one sliding groove 212
However, the present invention is not limited to a pair, but is provided with two parallel sliding grooves opposed to each other, and two parallel claw pieces 231 that can pass therethrough. The two claw pieces may be provided so as to face the long axis so as to face the long axis.

In the case where an engaging projection having a length equal to the width of the claw piece 231 is provided, it is impossible to design a helical cylinder which is screwed and engaged with the engaging projection. Similarly to the second embodiment, if an engaging projection is forcibly provided on the short axis side, and it is screwed into the helical cylinder on the container body side, and it is attempted to engage the sliding groove on the front cylinder side, The width of the claw piece 231 must be reduced, and the rod axis of the push rod also becomes thin.

From the above results, in the case of the rod-shaped decorative material core C used in the rod-shaped decorative material feeding container of this embodiment which is long on the long axis side, the relay portion 233 is used as a rotation stopper on the front cylinder 210 side. Even if the shape itself is used as a detent,
3 may be used as a rotation stopper, but the engaging projection 235 is provided in the longitudinal direction, and is extended and successively engaged with the through hole 214 to provide a safe and secure operation. The payout is realized.

Therefore, as apparent from FIGS. 11 and 12, the cross section of the rod shaft 238 of the push rod 230 is manufactured as a substantially rectangular shape which can pass through the through hole 214 of the front cylinder 210, and the engaging projection 235 is Rod shaft 2 as an engagement protrusion similar to
38.

As shown in FIG. 13, the core material such as the rod-shaped decorative material core C in this embodiment having an extremely elliptical shape forms the tip of the front cylinder 210 as shown in FIG. An unprecedented makeup method can be realized by adopting a method that allows makeup on one side in the axial direction.

The O-ring 4 is the same as the O-ring 4 of the second embodiment.
It has the same meaning as the ring 3.
