The screw thread pitch of a female thread portion 9'f of a fitting cylinder 9 to which screwing projections 8d of a pipe holder 8 threadedly engages, is made larger than the screw thread pitch of a female thread portion 8'g of the pipe holder 8 to which male thread portion 11a of the push rod 11 threadedly engages. Accordingly, evaporation of a volatile component is prevented and deterioration of the cosmetic is prevented, the eyeliner being soft is readily handled in the production work, and further the rotation of a shaft cylinder quickly moves a pipe integrated with the pipe holder forward, and then the push rod is finely moved forward, so that the cosmetic stick is quickly dispensed as much as necessary.

Description

  The present invention relates to a container for holding a bar-shaped cosmetic material such as an eyeliner (hereinafter referred to as “bar-shaped cosmetic material”) in a freely drawable manner.

  2. Description of the Related Art Conventionally, there are containers that hold a bar-shaped cosmetic material so that the bar-shaped cosmetic material can be drawn out freely, and can be moved in and out by a knock or the like, and the bar-shaped cosmetic material is held by a core chuck composed of a plurality of claws. For this reason, the bar-shaped cosmetic material is gradually fed out according to the appearance of the core chuck.

  By the way, in recent years, stick-shaped cosmetics, especially eye liners, are made flexible for easy and reliable application, and after application, volatile components are mixed so that the eye liner is difficult to peel off. For this reason, when the flexible eyeliner is gripped so as to be freely drawn out by the lead chuck, the eyeliner is easily broken by the lead chuck and may not be sufficiently used.

  Thus, a container that can be fed out without breaking even a flexible eyeliner, that is, a cartridge-type cosmetic pencil has been proposed. That is, the cartridge-type cosmetic pencil includes a cartridge body comprising a pipe for housing a cosmetic core, a pipe holding member coupled to the periphery of the rear end of the pipe, and a cosmetic core stored in the pipe of the cartridge body. It consists of core extrusion means such as a core push rod to be extruded. Therefore, when the cosmetic core is fed out, the press plug and the pipe holding member are advanced by relatively rotating the spiral cylinder and the cartridge cylinder (first stage). Furthermore, by rotating the spiral cylinder and the cartridge cylinder relative to each other, the cosmetic core in the pipe is pressed by the pressing stopper, and is fed out from the front end opening of the cartridge cylinder (second stage) (patent) Reference 1).

  However, in the above-described cartridge-type cosmetic pencil, the two-stage cosmetic core feeding mechanism is realized by the maximum static frictional force between the press plug and the pipe holding member or the inner wall of the pipe. For this reason, when the maximum static frictional force decreases due to an error in the pipe inner diameter or the adhesion of the cosmetic core, the two-stage feeding mechanism in the cartridge-type cosmetic pencil does not operate correctly, and the cosmetic core in the pipe does not work. There is a possibility that the lead will be pulled out first by the core pushing rod and broken inside.

Further, the operation of the feeding mechanism in two stages in the cartridge type cosmetic pencil is based on the screwing of the protruding portion standing at the rear end of the core push rod and the female thread spiral groove in the spiral cylinder. That is, the feed amount in the two-stage feed mechanism depends on the screw pitch of the female screw spiral groove in the spiral cylinder.
For this reason, when the screw pitch of the female thread spiral groove in the spiral cylinder is large, the feeding amount in the first stage in which the pressing plug and the pipe holding member are advanced increases, and this is performed quickly. However, the pressing plug presses the cosmetic core in the pipe and the feeding amount in the second stage of feeding from the tip opening of the cartridge cylinder also becomes large, so the feeding amount cannot be finely adjusted and is necessary. The amount of cosmetic core cannot be paid out.
On the other hand, if the screw pitch of the female thread spiral groove in the spiral cylinder is small, the amount of feeding is reduced in the second stage of feeding the cosmetic core in the second stage, in which the cosmetic core in the pipe is pressed and fed out from the tip opening of the cartridge cylinder. Fine adjustment of the feeding amount can be performed, and only a necessary amount of the cosmetic core can be fed out. However, the feeding amount in the first stage of moving the pressing plug and the pipe holding member forward becomes small and cannot be performed quickly.

  In addition, if the cosmetic core is an eyeliner that becomes soft by mixing, for example, volatile components, it is difficult to grip the eyeliner as it is, so that the work efficiency in the manufacturing operation is lowered. Furthermore, if the volatile component mixed in the eyeliner evaporates, the flexibility is lost, the application cannot be performed easily and accurately, and the eyeliner easily peels off after application. For this reason, it is necessary to ensure the hermeticity in the container for holding the eyeliner so that the eyeliner can be extended.

Japanese Patent No. 3230796

  The problem to be solved is that the work efficiency in the manufacturing operation is lowered, the sealing property in the feeding container is ensured, and the bar-shaped cosmetic material cannot be fed out quickly and in a necessary amount.

As the first feature,
A cap, a shaft cylinder, and a feeding mechanism that is held by the shaft cylinder and feeds the stick-shaped cosmetic material,
The cap has an internal stopper,
The shaft cylinder holds a feeding mechanism,
The feeding mechanism has an opening at the front end, and has a feeding hole that forms a stepped portion projecting on the inner peripheral surface thereof, and a core cylinder that has an annular protruding edge around the rear end edge, A pipe for holding the bar-shaped cosmetic material, a pipe holding portion for fitting the pipe in the front, and a plurality of screw projections that can be bent in the radially inward direction at the rear, A pipe holder with an O-ring attached to the outer peripheral surface and a female threaded portion screwed into the inner peripheral surface of a through-hole drilled in the inside, and a concave annular holding portion that fits the annular projecting edge of the core cylinder forward In addition, a female screw portion into which the screw projection of the pipe holder is screwed is screwed in front of the ridge formed on the inner peripheral surface of the through hole formed in the inside, and the rear is described later. A fitting cylinder that forms a tooth profile that can be engaged with the tooth profile of the rotating cylinder, which will be described later A flange is formed at one end of a cylinder that has a through hole with a cross-sectional shape that is substantially the same as the cross-sectional shape of the rod, and a tooth profile that can be engaged with the tooth profile of the fitting cylinder is formed on the flange. The rotating cylinder and the cross-sectional shape of the rotating cylinder are substantially the same as the cross-sectional shape of the through-hole of the rotating cylinder, and a male screw portion that is screwed to the female screw portion screwed into the through-hole of the pipe holder is screwed on the outer peripheral surface. It consists of a push rod that
The core cylinder and the fitting cylinder are integrally fitted to the concave annular holding portion of the fitting cylinder that is rotated by the shaft cylinder so that the annular projecting edge of the core cylinder can be relatively rotated,
The pipe and the pipe holder are integrally fitted to the pipe holding portion of the pipe holder, and are loosely fitted to the core tube so as not to rotate with either the pipe or the pipe holder.
The pipe and the core cylinder are capable of locking the pipe to the step formed on the inner peripheral surface of the feeding hole of the core cylinder,
The core tube and the pipe holder are closely attached to the outer peripheral surface of the pipe holder with the O-ring attached to the outer peripheral surface of the core cylinder,
The fitting cylinder and the pipe holder are screwed into the threaded protrusion of the pipe holder to the female thread portion on the inner peripheral surface of the through hole of the fitting cylinder,
The fitting cylinder and the rotating cylinder mesh with each other so that the fitting cylinder and the rotating cylinder form a ratchet mechanism that can rotate together only during a right rotation,
The push rod and the pipe holder are attached to the rear end of the bar-shaped cosmetic material held in the pipe that fits together with the pipe holder with respect to the female thread portion screwed on the inner peripheral surface of the through hole inside the pipe holder. Screw the male thread part of the push rod that comes into contact
The rotating cylinder and the push rod pass through the push rod that can be moved forward and backward in the axial direction and locked in the rotating direction with respect to the through hole of the rotating cylinder.
The screw pitch in the female screw portion of the fitting cylinder is made larger than the screw pitch of the female screw portion of the pipe holder.

Therefore, when the shaft cylinder is rotated to the right in order to pay out the bar-shaped cosmetic, the pipe holder integrated with the pipe holding the bar-shaped cosmetic inside through the fitting cylinder rotating in the same direction rapidly advances, Further, the bar-shaped cosmetic material held in the pipe is gradually pushed out by the push bar integrated with the rotating cylinder connected to the fitting cylinder via the ratchet mechanism. As a result, the stick-shaped cosmetic can be delivered quickly and as many times as necessary. Further, when the shaft cylinder is rotated counterclockwise, the ratchet mechanism for connecting the fitting cylinder and the rotating cylinder is dissociated, and the pipe holder is also retracted from the feeding hole inside the core cylinder. As a result, the rod-shaped cosmetic and the pipe holding the pipe can be accommodated in the core cylinder.
Here, the stick-shaped cosmetic material delivery container of the present invention is disposable from the viewpoint of hygiene, in addition to being able to replace the pipe that holds the stick-shaped cosmetic material in terms of the environment and cost for long-term use. It is good.

And since the flexible stick-shaped cosmetic is held in the pipe and the pipe itself is used as a part of the feeding container, it is possible to prevent breakage of the stick-shaped cosmetic in the manufacturing process and improve the work efficiency. .
In addition, the rod-shaped cosmetics that are held in the pipe that can be moved forward and backward in the feeding hole of the core cylinder, the opening part of the feeding hole of the core cylinder is an inner plug installed in the cap, and the side surface is on the outer peripheral surface of the pipe holder. Since the O-ring to be mounted and the rear side are hermetically sealed by the front surface, side surface, and pipe inner surface of the push rod, it is possible to prevent the volatile component from evaporating from the bar-shaped cosmetic material and deteriorating.

Based on the first feature, as the second feature,
In the said pipe, a packing is hold | maintained with a rod-shaped cosmetics.

  Therefore, the bar-shaped cosmetics held in the pipe are, as described above, the opening part of the feeding hole of the core tube being the inner plug that is built in the cap, the side surface being the O-ring attached to the outer peripheral surface of the pipe holder, The rear side is not only hermetically sealed by the front and side surfaces of the push rod and the inner surface of the pipe, but especially the inside of the pipe is hermetically sealed by the deformation of the packing that is held together with the bar-shaped cosmetic material. It can prevent more reliably that a volatile component evaporates from cosmetics and deteriorates.

Based on the first feature or the second feature, as the third feature,
Instead of the inner plug in the cap, a tail plug is tightly fitted to the opening at the rear end of the fitting cylinder, and an O-ring is attached to the outer peripheral surface of the fitting cylinder.

  Therefore, the opening portion of the feed hole formed by holding the pipe for holding the bar-shaped cosmetic so as to advance and retreat is hermetically sealed by the close contact between the O-ring attached to the outer peripheral surface of the fitting cylinder and the inner peripheral surface of the cap. Located in the cap, the rear of the pipe is hermetically sealed by a tail plug that fits tightly into the opening at the rear end of the fitting cylinder. As a result, it can prevent more reliably that a volatile component will evaporate and deteriorate from a stick-shaped cosmetic.

  In the present invention, the pipe to be melt-filled when producing the bar-shaped cosmetic is used as it is as a part of the feeding container, and the bar-shaped cosmetic held in the pipe is hermetically sealed to evaporate and deteriorate the volatile components. In the feeding mechanism disposed in the shaft cylinder, the rotation of the shaft cylinder is transmitted to the pipe holder through the fitting cylinder to advance the pipe, and further through the fitting cylinder and the rotating cylinder. By pushing the stick-shaped cosmetic material that is transmitted to the push rod and held in the pipe that is integrated with the pipe holder, the work efficiency in the manufacturing operation can be sufficiently improved, and it is necessary quickly. Since the stick-shaped cosmetic is fed out only, it has an excellent effect that can be used for a long period of time.

  Holds the internal plugs and stick-shaped cosmetics that are built into the cap so that it can be delivered quickly and in the required amount without deteriorating the stick-shaped cosmetics containing volatile components, improving the work efficiency in manufacturing operations. The O-ring attached to the pipe holder integrated with the pipe to be connected and the push rod, or the O-ring attached to the outer peripheral surface of the fitting cylinder, and hermetically sealed by a tail plug that fits tightly into the opening at the rear end of the fitting cylinder In addition, the thread pitch of the female threaded portion of the fitting cylinder that is screwed with the pipe holder is made larger than the thread pitch of the female threaded portion of the pipe holder that is threadedly engaged with the push rod. It was realized with different.

  FIG. 1 shows a stick-shaped cosmetic material delivery container 1 that is Embodiment 1 of the present invention. The bar-shaped cosmetic material supply container 1 includes a cap 2, a shaft tube 3, and a feeding mechanism A that is arranged in the shaft tube 3 and that gradually supplies the eyeliner 13 that is a bar-shaped cosmetic material.

  Here, the cap 2 includes a serrated stop projection 2a on the inner peripheral surface of the opening, and an inner plug 2b that hermetically seals an opening 6a at the tip of the core tube 6 described later.

  Further, the barrel 3 is fitted with a tail plug 4 at its rear end.

  The feeding mechanism A is mainly composed of a core cylinder 6, a molded pipe 7, a pipe holder 8, a fitting cylinder 9, a rotating cylinder 10, and a push rod 11, and each part is as follows. It is what.

The core cylinder 6 has a feed hole 6b in which an inner diameter of an opening 6a is larger than an outer diameter of a molding pipe 7 described later, and an annular projecting edge 6e around the rear end edge. Two anti-rotation projections 6c are provided in the axial direction so as to face the front of the inner peripheral surface of the feeding hole 6b, and a step portion 6f to which a molded pipe 7 described later can be locked is formed in the feeding hole 6b. It is formed in an annular shape so as to protrude on the inner peripheral surface.
The molded pipe 7 holds the eyeliner 13 therein, and has four sets of rotation stop grooves 7a arranged in parallel in the axial direction on the large-diameter portion 7c formed so as to protrude in the radial direction on the outer peripheral surface thereof. The locking projections 7b are evenly arranged.
The pipe holder 8 has a concave shape in which engagement holes 8a and slits 8b that engage and loosely engage with the locking projections 7b of the molded pipe 7 are disposed evenly and alternately at the front. A pipe holding portion 8c is formed, and at the rear side, two screw projections 8d that are screwed into a female screw portion 9f of a fitting cylinder 9 (to be described later) and can be bent in the radial inward direction are arranged to face each other. An O-ring 8e is mounted in a circumferential groove 8h on the outer peripheral surface, and a female screw portion 8g is screwed on the inner peripheral surface of a through hole 8f that passes through the inside.
The fitting tube 9 has four locking protrusions 9a that engage with the rotation protrusions 2a provided on the outer peripheral surface of the cap 2 on the outer peripheral surface thereof so as to face each other. And a concave annular holding portion 9b into which the annular projecting edge 6e at the rear end edge of the core tube 6 is fitted, and a projecting rim provided around the inner peripheral surface of the shaft tube 3 at the rear. In the through hole 9d in which the bush 5 is closely fitted to the rear end of the female screw portion 9c to be screwed with the screw 3a, the pipe is disposed in front of the projecting edge 9e formed substantially at the center. A female thread portion 9f that is screwed with the screw protrusion 8d of the holder 8 is screwed, and a tooth profile portion 9g that meshes with a tooth profile portion 10c of the rotary cylinder 10 to be described later is integrally formed on the rear side of the protrusion edge 9e. is doing.
The rotary cylinder 10 is formed with a flange portion 10a at one end of the cylinder, and has a through hole 10b having a substantially elliptical cross section substantially the same as the cross section of a push rod 11 described later. In the flange portion 10a, the tooth profile portion 10c forming the ratchet mechanism B that can be engaged only with a rotation in a fixed direction, that is, clockwise rotation with the tooth profile portion 9g of the protruding edge 9e of the fitting tube 9. Are integrally formed.
The push bar 11 has a substantially elliptical shape whose cross-sectional shape is substantially the same as the through hole 10b of the rotary cylinder 10, and a male screw portion 11a is screwed in the axial direction on the curved surface. In addition, a pressing portion 11b that abuts the rear end of the eyeliner 13 and pushes it forward is integrally formed at the tip.

As described above, since the parts of the feeding mechanism A are configured, each part is connected as follows.
First, the core tube 6 and the fitting tube 9 are such that the annular projecting edge 6e at the rear end edge of the core tube 6 is rotatable relative to the concave annular holding portion 9b in front of the fitting tube 9. Are fitted together so that The fitting cylinder 9 and the shaft cylinder 3 are female threads that are screwed behind the outer peripheral surface of the fitting cylinder 9 with respect to the ridge edge 3b that is provided around the inner peripheral surface of the shaft cylinder 3. The portion 9c is screwed so that it cannot move forward and is relatively rotatable.
Secondly, the molded pipe 7 and the pipe holder 8 are integrally fitted with a rear end edge of the molded pipe 7 and a pipe holding portion 8c formed in front of the pipe holder 8, and the molded pipe 7 A locking projection 7b protruding from the outer peripheral surface and an engagement hole 8a and a slit 8b disposed in a pipe holding portion 8c formed in front of the pipe holder 8 are integrally engaged and loosely fitted. .
Thirdly, the core tube 6 and the molded pipe 7 are opposed to the two rotation protrusions 6c that are provided so as to face each other on the inner peripheral surface of the feed hole 6b formed in the core tube 6. Of the four grooves formed on the outer peripheral surface of the molded pipe 7, two stop grooves 7a are loosely fitted so as to be movable forward and backward in the axial direction. Further, as the forming pipe 7 advances, the leading edge 7d of the large diameter portion 7c of the forming pipe 7 is engaged with the step portion 6f formed to protrude from the inner peripheral surface of the feeding hole 6b of the core tube 6. It can be stopped freely. When assembling the core tube 6 and the molded pipe 7, the rotation grooves 7a of the molded pipe 7 are evenly arranged on the outer peripheral surface so that the rotation protrusions 6c of the core tube 6 face each other. By inserting the molding pipe 7 into the core cylinder 6 and rotating it by a maximum of 45 °, the anti-rotation projection 6c of the core cylinder 6 and the anti-rotation groove 7a of the molding pipe 7 are surely loosely fitted, so that the working efficiency is improved. Is.
Fourth, the O-ring 8e attached to the outer peripheral surface of the pipe holder 8 is in close contact with the inner peripheral surface of the feeding hole 6b formed in the core cylinder 6 between the core cylinder 6 and the pipe holder 8. Yes.
Fifth, the fitting cylinder 9 and the pipe holder 8 are opposed to the rear side of the pipe holder 8 with respect to the female screw portion 9f screwed into the through hole 9d drilled in the fitting cylinder 9. The two screw projections 8d arranged in this manner are screwed together to transmit the rotation of the fitting cylinder 9.
Sixth, the fitting tube 9 and the rotating tube 10 are formed on the flange portion 10a of the rotating tube 10 with respect to the tooth profile portion 9g formed on the rear side of the protruding edge 9e on the inner peripheral surface of the fitting tube 9. The tooth profile portion 10c forms a ratchet mechanism that can be meshed only when rotated clockwise. For this reason, when the eyeliner 13 is applied, both the tooth profile portions 9g and 10c mesh with each other and rotate clockwise, and after the eyeliner 13 application, the both tooth profile portions 9g and 10c are separated from each other.
Seventh, the push rod 11 and the pipe holder 8 have a circular cross-sectional shape, and the push rod 11 is opposed to the female screw portion 8g screwed on the inner peripheral surface of the through hole 8f inside the pipe holder 8. The male screw portion 11a is screwed.
Eighth, the push rod 11 and the rotating cylinder 10 can advance in the axial direction in the through hole 10b of the rotating cylinder 10, and are locked to each other and rotate integrally with the rotation of the rotating cylinder 10. Has penetrated. That is, at least a part of the through hole 10b of the rotating cylinder 10 and the cross-sectional shape of the push rod 11 are substantially the same elliptical shape, so that they can move forward in the axial direction and are locked together when the rotating cylinder 10 rotates. And rotate together.

  In addition, the screw pitch of the female screw portion 9f of the fitting cylinder 9 to which the screw protrusion 8d of the pipe holder 8 is screwed is larger than the screw pitch of the female screw portion 8g of the pipe holder 8 to which the male screw portion 11a of the push rod 11 is screwed. Has also become large. Therefore, the advance distance of the pipe holder 8 with respect to the rotation of the shaft cylinder 3 is larger than the advance distance of the push rod 11. As a result, the pipe holder 8 can be rapidly advanced, and the eyeliner 13 in the extruded pipe 7 can be fed out as accurately as necessary.

Since the feeding mechanism A provided in the bar-shaped cosmetic material feeding container 1 according to the first embodiment of the present invention is as described above, the bar-shaped cosmetic material feeding container 1 operates as follows. .
First, when the eyeliner 13 is fed out, the cap 2 is removed from the shaft tube 3 and then the shaft tube 3 is rotated clockwise. Therefore, the rotation of the shaft tube 3 is not possible to advance with respect to the projecting edge 3a provided on the inner peripheral surface of the shaft tube 3, and the female thread portion 9c is screwed so as to be relatively rotatable. Is transmitted to the fitting cylinder 9 which is screwed, and the fitting cylinder 9 also rotates in the same direction.
Further, the rotation of the fitting cylinder 9 is transmitted to the pipe holder 8 provided with a screw projection 8d that is screwed into the female screw portion 9f of the fitting cylinder 9. At this time, the rotation projection 6c protruding from the inner peripheral surface of the feeding hole 6b of the core tube 6 and the rotation groove 7a of the molded pipe 7 integrated with the pipe holder 8 are free to move in the axial direction. Since the pipe holder 8 is fitted, the pipe holder 8 is rapidly advanced to a predetermined position so as to protrude from the opening 6a of the core tube 6 together with the molded pipe 7 and is held firmly. That is, when the forming pipe 7 moves forward through the feeding hole 6 b of the core tube 6, it projects so as to protrude from the tip edge 7 d of the large diameter portion 7 c of the forming pipe 7 and the inner peripheral surface of the feeding hole 6 b of the core tube 6. The step 6f to be formed is locked, and the advancement is stopped. As a result, the screw projection 8d of the pipe holder 8 that is screwed into the female screw portion 9f of the fitting cylinder 9 does not exceed the foremost end of the female screw portion 9f, and the screw projection 8d of the pipe holder 8 has a diameter in the vicinity of the foremost end. Since the inner tube portion 9f of the fitting tube 9 is disengaged by being bent inward, the fitting tube 9 is idled with respect to the pipe holder 8.
As the pipe holder 8 advances, the rotary cylinder 10 that is constantly pushed forward by the spring 12 behind the through hole 9d of the fitting cylinder 9 advances toward the rear end of the pipe holder 8. Therefore, the tooth profile portion 9g of the projecting edge 9e formed in the through hole 9d of the fitting cylinder 9 and the tooth profile section 10c formed on the flange portion 10a of the rotary cylinder 10 are engaged with each other to thereby establish the ratchet mechanism B. It will be an eggplant. At this time, when the fitting cylinder 9 that rotates integrally with the shaft cylinder 3 rotates to the right, the ratchet mechanism B engages both 9g and 10c and transmits the rotation of the fitting cylinder 9 to the rotating cylinder 10. When the fitting cylinder 9 rotates counterclockwise, the meshing of both 9g and 10c is released, and the rotation of the fitting cylinder 9 is not transmitted to the rotating cylinder 10.
Then, when the shaft cylinder 3 is further rotated to the right, the fitting cylinder 9 and the rotating cylinder 10 are connected via the ratchet mechanism B, so that the rotation of the shaft cylinder 3 is transmitted and the rotating cylinder 10 is moved to the right. Rotate. At this time, since the push rod 11 penetrating the through hole 10b of the rotating cylinder 10 is locked with the through hole 10b of the rotating cylinder 10, the rotating cylinder 10 and the push rod 11 rotate integrally.
As a result, the push rod 11 screwed with the female screw portion 8g screwed on the inner peripheral surface of the through hole 8f of the pipe holder 8 advances while rotating, so that the push rod 11 is held in the molded pipe 7. The eyeliner 13 is pressed from the rear end and can be fed out as necessary.

On the other hand, after use, the fitting cylinder 9 rotates counterclockwise by rotating the shaft cylinder 3 counterclockwise. Therefore, in the ratchet mechanism B that connects the fitting cylinder 9 and the rotating cylinder 10, the engagement between the tooth profile portion 9 g of the fitting cylinder 9 and the tooth profile portion 10 c of the rotating cylinder 10 is dissociated and the rotating cylinder 10 becomes free. At the same time, the pipe holder 8 to which the screw projection 8d on the outer peripheral surface is screwed is also retracted with respect to the female screw portion 9f screwed on the inner peripheral surface of the through hole 9d of the fitting cylinder 9. As a result, the molded pipe 7 that has been advanced so as to protrude from the opening 6 a of the core cylinder 6 is retracted into the feeding hole 6 b of the core cylinder 6. As a result, the molded pipe 7 is accommodated in the feeding hole 6 b of the core tube 6 together with the eyeliner 13 fed out from the molded pipe 7. That is, the pipe holder 8 that retreats in the core cylinder 6 is configured such that the rear end edge of the pipe holder 8 comes into contact with the protruding edge 9e of the fitting cylinder 9 so that the retraction of the pipe holder 8 is stopped. As a result, the screw projection 8d of the pipe holder 8 screwed into the female thread portion 9f of the fitting cylinder 9 does not exceed the rear end of the female screw portion 9f, and the screw projection 8d of the pipe holder 8 is near the rear end. Since the inner tube portion 9f of the fitting tube 9 is disengaged by being bent inward, the fitting tube 9 is idled with respect to the pipe holder 8.
Then, the cap 2 is integrally attached to the shaft tube 3 while engaging the rotation protrusion 2a provided on the inner peripheral surface of the opening of the cap 2 and the locking protrusion 9 provided on the fitting tube 9. It is made. At this time, the inner plug 2b housed in the cap 2 hermetically seals the opening 6a of the feeding hole 6b.

  When the cap 2 is attached to the shaft cylinder 3, the eyeliner 13 held inside the molding pipe 7 is housed in the cap 2 with the front opening 6 a inside the feeding hole 6 b inside the core cylinder 6. Further, the inner plug 2a is attached to the outer peripheral surface of the pipe holder 8 integrated with the molded pipe 7, the O-ring 8e is in close contact with the inner peripheral surface of the feeding hole 6b of the core tube 6, and the rear is the push rod 11b. It is hermetically sealed by the front surface, the side surface, and the inner surface of the molded pipe 7. Therefore, the eyeliner 13 held in the molded pipe 7 can maintain flexibility without volatilizing the volatile components contained therein.

FIG. 6 shows a modified example 1a of the bar-shaped cosmetic material supply container 1 according to the first embodiment of the present invention. The structure of the bar-shaped cosmetic material supply container 1a, particularly the coupling and operation of the components of the supply mechanism A are shown. Is substantially the same as that of the stick-shaped cosmetic material delivery container 1 according to the first embodiment of the present invention.
However, the molding pipe 7 is different from the feeding mechanism A of the stick-shaped cosmetic material feeding container 1 according to the first embodiment of the present invention in that a packing 15 made of an elastic material is housed in the rear end of the eyeliner 13. Is.

  Since the modified example 1a of the stick-shaped cosmetic material delivery container 1 which is the first embodiment of the present invention is configured as described above, similarly to the feeding mechanism A of the stick-shaped cosmetic material delivery container 1 which is the first embodiment of the present invention, After the shaft holder 3 is rotated, the pipe holder 8 is rapidly advanced to a predetermined position so that the molded pipe 7 protrudes from the opening 6a of the core cylinder 6 through the fitting cylinder 9 and the rotary cylinder 10, By moving the push rod 11 forward, the eyeliner 13 held in the molding pipe 7 is extruded and fed out from the molding pipe 7 or accommodated in the core cylinder 6. At this time, since the packing 15 is held together with the eyeliner 13 in the molded pipe 7, the eyeliner 13 is pushed out together with the packing 15 by the push rod 11 and fed out.

This is different from the stick-shaped cosmetic material supply container 1 according to the first embodiment of the present invention in that an O-ring 16 is attached so as to be in close contact with the inner peripheral surface.

  Since the modified example 1b of the bar-shaped cosmetic material delivery container 1 according to the first embodiment of the present invention is configured as described above, similarly to the feeding mechanism A of the bar-shaped cosmetic material delivery container 1 according to the first embodiment of the present invention, After the shaft holder 3 is rotated, the pipe holder 8 is rapidly advanced to a predetermined position so that the molded pipe 7 protrudes from the opening 6a of the core cylinder 6 through the fitting cylinder 9 and the rotary cylinder 10, By moving the push rod 11 forward, the eyeliner 13 held in the molding pipe 7 is extruded and fed out from the molding pipe 7 or accommodated in the core cylinder 6.

  When the cap 2 is attached, the eyeliner 13 held inside the molding pipe 7 has a fitting cylinder in which the opening 6a of the feeding hole 6b of the core cylinder 6 in which the molding pipe 7 is held so as to be movable forward and backward. 9 is located in the cap 7 that is hermetically sealed by the close contact between the O-ring 16 attached to the outer peripheral surface of the cap 9 and the inner peripheral surface of the cap 7, and the rear of the molded pipe 7 is at the opening of the rear end of the fitting cylinder 9 Since it is hermetically sealed by the tightly fitting tail plug 17, it is possible to more reliably prevent the volatile components of the eyeliner 13 from evaporating and deteriorating.

  FIG. 8 shows a stick-shaped cosmetic material delivery container 1 ′ that is Embodiment 2 of the present invention. And this stick-shaped cosmetics delivery container 1 'is arrange | positioned in cap 2', axial cylinder 3 ', and this cap 2' and axial cylinder 3 'similarly to Example 1, and eyeliner which is stick-shaped cosmetics It is composed of a feeding mechanism A ′ that is obtained by gradually feeding 13 ′.

  Here, the cap 2 ′ is provided with a sawtooth-shaped detent 2′a on the inner peripheral surface of the opening as in the first embodiment, and the opening 6′a at the tip of the core tube 6 ′, which will be described later, is sealed. An inner plug 2′b is sealed.

  Further, unlike the first embodiment, the shaft cylinder 3 ′ has a small hole 14 formed at the rear end thereof.

  The feeding mechanism A ′ is mainly composed of a core cylinder 6 ′, an extruded pipe 7 ′, a pipe holder 8 ′, a fitting cylinder 9 ′, a rotating cylinder 10 ′, and a push bar 11 ′, as in the first embodiment. Is. The parts constituting the feeding mechanism A 'are as follows.

The core cylinder 6 ′ has a feeding hole 6′b having an inner diameter of an opening 6′a that is substantially the same as an eyeliner 13 ′ held in an extrusion pipe 7 ′, which will be described later. An annular projecting edge 6'e is provided around the edge, and a stepped portion 6'f is formed in an annular shape immediately inside the opening 6'a on the inner peripheral surface of the feed-out hole 6'b. In this way, two rotation stop grooves 6'd are provided.
The extruded pipe 7 'holds an eyeliner 13' inside.
The pipe holder 8 ′ is formed with a concave pipe holding portion 8′c for holding the rear end edge of the extruded pipe 7 ′ at the front, and at the rear with a feeding hole 6 ′ for the core cylinder 6 ′. b is provided with a rotation projection 8'i that is loosely fitted with a rotation groove 6'd that is provided in the inner peripheral surface of b, and is screwed with a female screw portion 9'f of a fitting cylinder 9 'that will be described later. In addition, two screw projections 8'd that can be bent in the radially inward direction are arranged so as to face each other, and an O-ring 8'e is provided in a circumferential groove 8'h on the outer peripheral surface thereof. While being mounted, an internal thread portion 8′g is screwed on the inner peripheral surface of the through hole 8′f inside.
The fitting cylinder 9 'has four locking ridges 9'a that engage with the rotation protrusions 2'a provided around the inner peripheral surface of the opening of the cap 2' on the outer peripheral surface. A concave annular holding portion 9 ′ b is formed so as to be opposed to each other and into which the annular protruding edge 6 ′ e at the rear end edge of the core tube 6 ′ is fitted. A male screw portion 9'h that is screwed with a female screw portion 3'b that is provided on the inner peripheral surface of the shaft cylinder 3 'is screwed, and the periphery is the inner peripheral surface of the shaft tube 3'. In the through-hole 9′d in which the rear end is closely fitted by the bush 5 ′ that is in close contact with the screw, the screw protrusion 8′d of the pipe holder 8 ′ is disposed in front of the protruding edge 9′e formed at the substantially center thereof. A female thread portion 9′f to be screwed is screwed and a tooth profile portion 9′g is formed on the rear side of the protruding edge 9′e.
The rotary cylinder 10 'is formed with a flange portion 10'a at one end of the cylinder, and has a through hole 10 having a substantially elliptical cross section substantially the same as the cross section of a push rod 11' described later. 'b is drilled, and the flange portion 10'a only rotates in a fixed direction with respect to the tooth profile portion 9'g of the protruding edge 9'e of the fitting tube 9, that is, to the right. A tooth profile portion 10′c that forms a ratchet mechanism B ′ that can be meshed is formed.
The push bar 11 'has a substantially elliptical shape whose cross-sectional shape is substantially the same as the cross-sectional shape of the through-hole 10'b of the rotary cylinder 10'. A is screwed in the axial direction, and a pressing portion 11′b that abuts the rear end of the eyeliner 13 ′ and pushes it forward is integrally formed at the tip.

As described above, since the components of the feeding mechanism A ′ are configured, each component is connected as follows.
First, the core cylinder 6 ′ and the fitting cylinder 9 ′ are configured such that the annular projecting edge 6′e at the rear end edge of the core cylinder 6 ′ is formed into a concave annular holding portion 9′b in front of the fitting cylinder 9 ′. They are integrally fitted so as to be relatively rotatable. The fitting tube 9 ′ and the shaft tube 3 ′ are screwed on the outer peripheral surface of the fitting tube 9 with respect to the female screw portion 3′b provided on the inner peripheral surface of the shaft tube 3 ′. The male screw portion 9′h is screwed so that it cannot move forward and is relatively rotatable.
Second, the extruded pipe 7 'and the pipe holder 8' are integrally fitted with a rear end edge of the extruded pipe 7 'and a pipe holding portion 8'c formed in front of the pipe holder 8'. .
Third, the core tube 6 ′ and the extruded pipe 7 ′ are held so as to be movable back and forth in the axial direction in the feed hole 6′b of the core tube 6 ′. Further, as the extruded pipe 7 ′ advances, the tip edge 7′a of the molded pipe 7 ′ has a stepped portion 6 formed immediately inside the opening 6′a of the feed hole 6′b of the core tube 6 ′. It can be locked to 'f.
Fourth, the core tube 6 ′ and the pipe holder 8 ′ are mounted on the outer peripheral surface of the pipe holder 8 ′ with respect to the inner peripheral surface of the feeding hole 6′b drilled in the core tube 6 ′. The O-ring 8′e is in close contact with the axial direction so as to be able to advance and retreat, and the outer periphery of the rotation stop groove 6′d provided in the inner peripheral surface of the feed hole 6′b of the core tube 6 ′. The anti-rotation protrusion 8′i disposed on the surface is loosely fitted so as to be movable back and forth in the axial direction.
Fifth, the fitting cylinder 9 ′ and the pipe holder 8 ′ are connected to the female screw portion 9′f screwed in the through hole 9′d bored in the fitting cylinder 9 ′. Two screw projections 8'd arranged to face the rear of the holder 8 are screwed together to transmit the rotation of the fitting cylinder 9 '.
Sixthly, the fitting cylinder 9 ′ and the rotating cylinder 10 ′ are configured such that the rotating cylinder 10 ′ is in contrast to the tooth profile portion 9′g formed on the rear surface of the protruding edge 9′e of the fitting cylinder 9 ′. The tooth profile portion 10′c formed on the flange portion 10′a can be meshed only when rotating clockwise. Therefore, when the eyeliner 13 'is applied, both tooth form portions 9'g and 10'c mesh with each other and rotate rightward together, and after the eyeliner 13' application, both tooth form portions 9'g and 10'c are dissociated from each other. Will be.
Seventh, the push rod 11 ′ and the pipe holder 8 ′ have a circular cross-sectional shape, and with respect to the female screw portion 8 ′ g screwed on the inner peripheral surface of the through hole inside the pipe holder 8 ′. Thus, the male thread portion 11′a of the push rod 11 ′ is screwed.
Eighth, the push rod 11 ′ and the rotating cylinder 10 ′ can be advanced in the axial direction in the through hole 10 ′ b of the rotating cylinder 10 ′, and are locked together with the rotation of the rotating cylinder 10 ′. It penetrates so as to rotate together. That is, at least a part of the through-hole 10′b of the rotating cylinder 10 ′ and the cross-sectional shape of the push bar 11 ′ are substantially the same elliptical shape, so that it can move forward in the axial direction, and the rotating cylinder 11 ′ can rotate. Sometimes they are locked together and rotate together.

  In addition, the thread pitch of the female thread portion 9′f of the fitting cylinder 9 ′ into which the thread projection 8′d of the pipe holder 8 ′ is threaded is determined by the pipe holder in which the male thread portion 11′a of the push bar 11 ′ is threaded. It is larger than the thread pitch of the 8 ′ female thread portion 8′g. Therefore, the advance distance of the pipe holder 8 'relative to the rotation of the shaft cylinder 3' is larger than the advance distance of the push rod 11 '. As a result, the pipe holder 8 'can be rapidly advanced, and the eyeliner 13' in the extruded pipe 7 'can be fed out as accurately as necessary.

Since the feeding mechanism A ′ provided in the bar-shaped cosmetic material feeding container 1 ′ according to the second embodiment of the present invention is as described above, the bar-shaped cosmetic material feeding container 1 ′ operates as follows. Is.
First, when the eyeliner 13 'is extended, the shaft cylinder 3' is rotated after removing the cap 2 'from the shaft cylinder 3'. Therefore, the rotation of the shaft tube 3 'is a male screw portion 3'b that is provided around the inner peripheral surface of the shaft tube 3' and cannot be moved forward and is screwed so as to be relatively rotatable. Since the screw portion 9′h is transmitted to the fitting cylinder 9 ′, the fitting cylinder 9 ′ is also rotated in the same direction.
Further, the rotation of the fitting cylinder 9 ′ is transmitted to the pipe holder 8 ′ provided with a screw projection 8′d that is screwed into the female screw portion 9′f of the fitting cylinder 9 ′. At this time, the stop groove 6'd formed in the inner peripheral surface of the feed hole 6'b of the core tube 6 'and the stop protrusion 8'i of the pipe holder 8' can advance and retreat in the axial direction. Since the pipe holder 8 ′ and the extruded pipe 7 ′ do not rotate, the pipe holder 8 ′ and the extruded pipe 7 ′ are rapidly advanced to a predetermined position in the feeding hole 6′b of the core tube 6 ′ and are held firmly. It becomes. That is, when the extruded pipe 7 ′ advances through the feeding hole 6′b of the core cylinder 6 ′, the leading edge 7′a of the extruded pipe 7 ′ and the inner peripheral surface of the feeding hole 6′b of the core cylinder 6 ′. The step 6′f formed immediately inside the opening 6′a is locked, and the advancement stops. As a result, the screw projection 8′d of the pipe holder 8 ′ that is screwed into the female screw portion 9′f of the fitting cylinder 9 ′ does not exceed the foremost end of the female screw portion 9′f, and in the vicinity of the foremost end, Since the screw protrusion 8'd of the pipe holder 8 'bends inward in the radial direction and the threaded engagement with the female thread portion 9'f of the fitting cylinder 9' is dissociated, the fitting cylinder 9 'is connected to the pipe holder 8'. Is idle.
Then, as the pipe holder 8 ′ advances, the tip of the rotary cylinder 10 ′ that is always pushed forward by the spring 12 ′ behind the through hole 9′d of the fitting cylinder 9 ′ has a pipe holder 8 ′. Move forward toward the rear edge. Therefore, the tooth profile portion 9′g of the ridge 9′e formed in the through hole 9′d of the fitting cylinder 9 ′ and the tooth profile section 10 ′ formed on the flange portion 10′a of the rotary cylinder 10 ′. c and mesh with each other to form a ratchet mechanism B ′. At this time, when the fitting cylinder 9 ′ that rotates integrally with the shaft cylinder 3 ′ rotates to the right, the ratchet mechanism B ′ engages both 9′g and 10′c to rotate the fitting cylinder 9 ′. When the fitting cylinder 9 'rotates counterclockwise, the engagement between the two 9'g and 10'c is released, and the rotation of the fitting cylinder 9' is not transmitted to the rotating cylinder 10 '. It is.
Then, when the shaft cylinder 3 ′ is further rotated to the right, the fitting cylinder 9 ′ and the rotating cylinder 10 ′ are connected via the ratchet mechanism B ′, so that the rotation of the shaft cylinder 3 ′ is transmitted, The rotating cylinder 10 ′ rotates clockwise. At this time, the push rod 11 ′ passing through the through hole 10′b of the rotating cylinder 10 ′ is locked with the inner peripheral surface of the through hole 10′b of the rotating cylinder 10 ′. 'And the push rod 11' rotate together.
As a result, the push rod 11 ′ screwed with the female screw portion 8 ′ g screwed on the inner peripheral surface of the through hole 8 ′ f of the pipe holder 8 ′ moves forward while rotating, so that the push rod 11 ′ The eyeliner 13 ′ held in the extruded pipe 7 ′ can be pressed from the rear end and fed out as necessary.

On the other hand, after use, the fitting cylinder 9 'rotates counterclockwise by rotating the shaft cylinder 3' counterclockwise. Therefore, in the ratchet mechanism B ′ that connects the fitting cylinder 9 and the rotating cylinder 10 ′, the engagement between the tooth profile portion 9′g of the fitting cylinder 9 ′ and the tooth profile section 10′c of the rotating cylinder 10 ′ is dissociated. Thus, the rotating cylinder 10 'becomes free, and a screw projection 8'd on the outer peripheral surface is formed on the inner thread surface 9'f screwed on the inner peripheral surface of the through hole 9'd of the fitting cylinder 9'. The pipe holder 8 ′ to be screwed also moves backward. As a result, the extruded pipe 7 ′ that has advanced in the feeding hole 6′b inside the core cylinder 6 ′ moves backward in the core cylinder 6 ′, and thus the eyeliner 13 ′ that has been fed out from the extruded pipe 7 ′ is also used. It will be accommodated in the core cylinder 6 '. That is, the pipe holder 8 ′ retreating in the core cylinder 6 ′ has the rear end edge of the pipe holder 8 ′ abutting against the protruding edge 9 ′ e of the fitting cylinder 9 ′, so that the pipe holder 8 ′ The retreat stops. As a result, the screw protrusion 8′d of the pipe holder 8 ′ screwed into the female thread portion 9′f of the fitting cylinder 9 ′ does not exceed the rearmost end of the female thread portion 9′f, and in the vicinity of the rearmost end, Since the screw protrusion 8'd of the pipe holder 8 'bends inward in the radial direction and the threaded engagement with the female thread portion 9'f of the fitting cylinder 9' is dissociated, the fitting cylinder 9 'is connected to the pipe holder 8'. Is idle.
Then, the cap 2 ′ is engaged with the rotation protrusion 2′a provided on the inner peripheral surface of the opening of the cap 2 ′ and the engaging protrusion 9′a provided on the fitting cylinder 9 ′. It is integrally mounted on the shaft cylinder 3 ′. At this time, the inner plug 2′b housed in the cap 2 ′ hermetically seals the opening 6′a of the feeding hole 6′b.

  In the state where the cap 2 ′ is mounted on the shaft cylinder 3 ′, the eyeliner 13 ′ held inside the extruded pipe 7 ′ has a front opening in the feeding hole 6′b inside the core cylinder 6 ′. 6'a is an inner plug 2'b built in the cap 3, and the side surface is attached to the outer peripheral surface of a pipe holder 8 'integrated with the extruded pipe 7', and is an O-ring that is in close contact with the inner peripheral surface of the core tube 6 '. 8′e and further rearward are hermetically sealed by the front and side surfaces of the push bar 11b and the inner surface of the extruded pipe 7 ′. Therefore, the eyeliner 13 ′ held in the extruded pipe 7 ′ can maintain flexibility without volatilizing the volatile components contained therein.

In the same manner as ′, by rotating the shaft cylinder 3 ′, the push-out rod 11 ′ is rapidly advanced to a predetermined position through the extrusion pipe 7 ′ integrated through the fitting cylinder 9 ′ and the rotation cylinder 10 ′. The eyeliner 13 ′ held in the extruded pipe 7 ′ is pushed out by being advanced and fed out from the opening 6′a of the extruded pipe 7 ′ and the core cylinder 6 ′ or accommodated in the core cylinder 6 ′. It will be. At this time, since the packing 15 ′ is held together with the eyeliner 13 ′ in the extrusion pipe 7 ′, the eyeliner 13 ′ is pushed out together with the packing 15 ′ by the push rod 11 ′ and fed out.

  In the state where the cap 2 'is mounted, the eyeliner 13' held inside the extruded pipe 7 'is in the feed hole 6'b inside the core tube 6', and the front opening 6'a is the cap. The inner plug 2'b is mounted inside 2 ', and the side surface is attached to the outer peripheral surface of the pipe holder 8' integrated with the extruded pipe 7 ', and the O-ring 8'e is in close contact with the inner peripheral surface of the core tube 6'. , And the rear side are hermetically sealed and accommodated by the front and side surfaces of the push rod 11 ′, the inner surface of the extruded pipe 7 ′, and the packing 15 ′. Therefore, the eyeliner 13 ′ held in the extruded pipe 7 ′ can reliably maintain flexibility without further volatilizing the volatile components contained therein.

  Although not shown, as a second modified example of the stick-shaped cosmetic material delivery container 1 ′ that is the second embodiment of the present invention, as in the modified example 1b of the stick-shaped cosmetic material feed container 1 that is the first embodiment of the present invention, Instead of the inner plug 2′a installed in the cap 2 ′, the tail plug is tightly fitted so that the opening at the rear end of the fitting tube 9 ′ is hermetically sealed, and the outer surface of the fitting tube 9 ′ is fitted. Some are provided with an O-ring so as to be in close contact with the inner peripheral surface of the cap 7 '. Therefore, in a state where the cap 2 ′ is mounted, the eyeliner 13 ′ held inside the extruded pipe 7 ′ is formed in the feeding hole 6′b of the core cylinder 6 ′ in which the extruded pipe 7 ′ is held so as to be movable forward and backward.
