The movable body 3 is inserted so as to be able to rotate synchronously with the engagement. It includes schematically a rotation stopper 2b, and that.

  Note that the direction of relative rotation between the front tube 1 and the container body 2 that is a sliding operation performed to advance the moving body 3 in the forward direction will be described as a feeding direction hereinafter.

  As shown in FIGS. 1 to 4, the front tube 1 has a cylindrical shape with both ends opened, and the front portion has an appearance that tapers toward a front end opening 1 c provided at the front end. And in the outer periphery of the rear part of the front tube 1 of this embodiment, the front tube 1 is provided with an annular recess 1b for engaging with the main body tube 2a of the container body 2 in a detachable and relatively rotatable manner, This rear portion is inserted into the main body cylinder 2a.

  Further, a housing portion 1a for housing the rod-like volatile cosmetic material 6 is provided inside the front portion of the front tube 1, and a piston body 5 that is slidable in close contact with the housing portion 1a is housed. The A female screw member 4b is inserted into the rear part of the front tube 1, and a plurality of protrusions 1d extending in the axial direction for engaging with the female screw member 4b so as to be capable of synchronous rotation are provided along the circumferential direction. ing.

  The volatile stick-shaped cosmetic 6 in the container 1a is a gel-shaped stick-shaped cosmetic used for an eyeliner, and contains cosmetic volatile oil. The cosmetic 6 has a weight of 0.15 g and contains 10% to 50% of a cosmetic volatile oil.

  The volatile sticky cosmetic material 6 is formed by being directly filled in the housing portion 1 a of the front tube 1 and is stored in close contact with the front tube 1.

  The diameter of the volatile sticky cosmetic 6 is a small diameter of 0.9 mm to 2.5 mm, and more preferably 1.2 mm to 2.5 mm. The reason for the small diameter (2.5 mm or less) is to draw a thin line drawn with a brush or a comb, for example.

  The measured hardness of the penetration test of the volatile sticky cosmetic 6 is 0.1 to 2 (N), and more preferably 0.15 to 1.5 (N). And by such hardness, the softness as a gel eyeliner can fully be hold | maintained. In addition, the hardness of the volatile sticky cosmetic material 6 is a hardness measured using a “FUDOH rheometer” manufactured by Rheotech Co., Ltd. As a measuring method thereof, when a cylindrical applicator having a diameter of 1 mm is inserted into the volatile sticky cosmetic material 6 at a depth of 10 mm under a measurement temperature of 25 ° C., the volatile sticky cosmetic product is inserted. The peak value occurring in the material 6 is measured. Such a measuring method is a general measuring method used for measuring hardness in cosmetics.

  The piston body 5 is formed from, for example, a thermoplastic elastomer (TPE) or the like, and is configured in a cylindrical shape as shown in FIGS. 1 to 4, 9, and 10. A concave portion 5d that is recessed toward the front side is formed on the rear end surface of the piston body 5, and a concave portion 5c that is similar in shape to the recessed portion 5d that is recessed toward the rear side is formed on the front end surface. Although these concave portions 5c and 5d are opposite in direction, the concave portions 5c and 5d have a shape that matches a truncated truncated cone-shaped tip (convex portion) 3c, which will be described later, of the movable body 3, and the cylindrical inner peripheral surface thereof is an axis line. The inside in the direction has a small diameter and the outside has a large diameter, and is configured to be gently inclined with respect to the axis of the piston body 5.

These annular projections 5a and 5b are in close contact with the inner peripheral surface of the accommodating portion 1a, and the width of the rear annular projection 5b (the width in the axial direction) is larger than the width of the front annular projection 5a. Has been enlarged.

  The piston body 5 is provided in close contact with the housing portion 1a so that when the moving body 3 moves in the feeding direction, the piston body 5 is pushed forward in conjunction with the movement of the moving body 3 to volatilize in the housing portion 1a. It plays a role of feeding the stick-shaped cosmetic 6 from the opening 1c of the front tube 1.

  And both the annular convex parts 5a and 5b of the piston body 5 have a function of keeping hermetically sealed by closely contacting and sliding on the inner peripheral surface of the accommodating part 1a. However, the wide annular convex part 5b on the rear side This contributes exclusively to securing the sealing property, and the narrow annular convex portion 5a on the front side exclusively contributes to suppressing the twist of the piston body 5 during forward movement and correcting the posture (details will be described later).

  As shown in FIGS. 1 to 3 and 5, the container body 2 is composed of a main body cylinder 2 a and a rotation stopper 2 b, and the rotation stopper 2 b is inserted from the rear end side of the main body cylinder 2 a to prevent rotation. 2b is engaged with the main body cylinder 2a so that it cannot move in the axial direction and can rotate synchronously. Then, the movable body 3, the spring member 4a, and the female screw member 4b are accommodated in the container body 2.

  The main body cylinder 2a has a cylindrical shape with both ends open. The rear part of the front cylinder 1 is inserted into the front part, and the rotation stopper 2b is inserted into the rear part of the main body cylinder 2a. And, on the inner peripheral surface of the front portion of the main body cylinder 2a of the present embodiment, since the front cylinder 1 is detachably engaged so as to be relatively rotatable, a convex section 2aa that can be engaged with the concave section 1b of the front cylinder 1 Is provided in an annular shape. Furthermore, a plurality of protrusions 2ad extending in the axial direction for engaging the spring member 4a so as to be able to rotate synchronously are provided on the inner peripheral surface of the front portion of the main body cylinder 2a along the circumferential direction. Further, on the inner peripheral surface of the rear portion of the main body cylinder 2a, an engagement protrusion 2ab for engaging the rotation stopper 2b so as not to move in the axial direction is provided in an annular shape, and for engaging the rotation stopper 2b so as to be synchronously rotatable. A plurality of protrusions 2ac extending in the axial direction are provided along the circumferential direction.

  The rotation stopper 2b includes an engagement groove 2ba formed along the circumferential direction for engaging with the engagement protrusion 2ab of the main body cylinder 2a on the outer peripheral surface thereof, and engages with the protrusion 2ac of the main body cylinder 2a. For this purpose, a plurality of protrusions 2bb extending in the axial direction are provided along the circumferential direction. Further, a rear portion of the moving body 3 is inserted into the inner peripheral surface of the rotation stopper 2b, and a rotation prevention groove (inner rotation prevention) 2bc for engaging the movement body 3 so as to be capable of synchronous rotation and movement in the axial direction. Are provided apart from each other in the circumferential direction over the entire length of the inner peripheral surface.

  As shown in FIGS. 1 to 3 and 6, the movable body 3 has a rod shape, and includes a male screw 3 a that can be screwed and connected to the female screw member 4 b on the outer periphery of the front half thereof. . Further, the outer periphery of the rear end of the movable body 3 engages with a rotation stop groove (inner peripheral rotation stop) 2bc so as to be slidable in the axial direction and non-rotatable in the circumferential direction when the movable body 3 is inserted into the rotation stopper 2b. A rotation stop projection (outer periphery rotation stop) 3b is provided.

  Further, the front end of the moving body 3 is provided with a tip 3c which is a convex portion protruding into a truncated cone shape having a small diameter on the front side and a large diameter on the rear side. The tip 3c has a shape matching the recesses 5c and 5d (see FIG. 10) of the piston body 5 accommodated in the front tube 1.

  The piston body 5 is separated from the moving body 3 and is disengaged (unconstrained). When the moving body 3 moves forward, the tip 3c of the moving body 3 enters the recess 5d on the rear side of the piston body 5. The piston body 5 is moved forward by being pushed by the moving body 3.

  The movable body 3 having such a configuration is disposed in the container main body 2 in a state of being screwed and coupled to the female screw member 4b. At this time, the rear portion of the moving body 3 is inserted into the rotation stopper 2b, and the rotation stopper protrusion 3b and the rotation stopper groove 2bc are engaged.

  The spring member 4a is a ratchet member, and as shown in FIGS. 1 to 3 and 7, has a cylindrical shape with both ends open, and an axially intermediate portion thereof contracts in the axial direction to receive an impact. A spiral spring portion 4aa having elasticity to be absorbed is formed, and a plurality of ratchet protrusions are protruded outward in the axial direction from one end (front end) of the spring member 4a at an axially front portion thereof. 4ab is formed along the circumferential direction. As shown in FIG. 7, the ratchet protrusion 4ab has a right triangle shape having an inclined surface inclined to one side and a surface extending perpendicularly to the axial direction. And this ratchet protrusion 4ab enables ratchet engagement with the female screw member 4b. Further, on the outer peripheral surface of the spring member 4a, a plurality of protrusions 4ac, 4ac extending in the outer peripheral surface axial direction sandwiching the spring portion 4aa from both sides in the axial direction are formed along the peripheral direction. When 4ac engages with the protrusion 2ad provided on the inner peripheral surface of the main body cylinder 2a of the container main body 2, the spring member 4a can rotate synchronously with the main body cylinder 2a.

  As shown in FIGS. 1 to 3 and 7, the female screw member 4 b is disposed in the main body cylinder 2 a and is inserted into the front cylinder 1. A female screw 4bb that is screwed into the male screw 3a is provided. The outer peripheral surface is provided with a plurality of protrusions 4bc extending in the axial direction along the circumferential direction, and the protrusions 4bc and the protrusions 1d of the front tube 1 are engaged with each other so that the front tube 1 and the female The screw member 4b can be rotated synchronously. Further, at the rear end of the female screw member 4b, there is formed a step portion (bump portion) 4bd with which the rear end of the front tube 1 abuts when inserted into the front tube 1, and a ratchet protrusion 4ab of the spring member 4a. A ratchet protrusion 4ba that can be engaged with the ratchet is formed.

  The above-described spring member 4a and female screw member 4b are ratchet-engaged, and the movable body 3 is screwed into the female screw member 4b inside the spring member 4a and female screw member 4b. Will be placed. At this time, the end (rear end) of the spring member 4a opposite to the side where the ratchet protrusion 4ab is formed contacts the end (front end) of the rotation stopper 2b. As shown in FIG. 3, before the leading tube 1 is inserted into the main body tube 2a, the spring member 4a and the female screw member 4b can rotate synchronously, and the spring member 4a and the female screw can be rotated. The member 4b is movable in the axial direction. Thereafter, when the front tube 1 is inserted into the main body tube 2a, the front tube 1 and the female screw member 4b are engaged with each other so as to be able to rotate synchronously, and opposite to the opening 1c of the front tube 1 being formed. Since the side end (rear end) contacts the front surface of the stepped portion 4bd of the female screw member 4b, the spring member 4a and the female screw member 4b are within the container main body 2 and the contraction range of the spring portion 4aa of the spring member 4a. It is accommodated in such a way that it can move in the axial direction only inside.

  The spring member 4a and the female screw member 4b rotate relative to each other in the feeding direction when the user relatively rotates the front tube 1 and the container body 2 in the feeding direction, and the ratchet engagement between the ratchet protrusion 4ab and the ratchet protrusion 4ba. The combination repeatedly releases the engagement and returns from the engagement, and makes a click sound and gives the user a click feeling. Thus, in the shape of the ratchet protrusion 4ab that engages with the ratchet, the spring member 4a and the female screw member 4b can be relatively rotated in the feeding direction, but cannot be rotated in the direction opposite to the feeding direction. Only relative rotation in the feeding direction is allowed. The ratchet engagement is such that when the thin volatile bar-shaped cosmetic material 6 is fed out by the rotation operation of the user, the shape of the small-diameter volatile bar-shaped cosmetic material 6 is gradually fed out. This is in order not to break down.

  Further, here, the male screw 3a of the moving body 3 and the female screw 4bb of the female screw member 4b have a pitch of 0.25 mm to 1 mm, more preferably 0.5 mm to 1 mm, and the number of threads is 1. Is formed. The small pitch (1 mm or less) and the number of strips are set in such a manner that when the thin volatile bar-shaped cosmetic material 6 is fed out by the rotation operation of the user, the shape of the small-sized volatile bar-shaped cosmetic material 6 is changed. This is in order not to break down.

  In addition, as shown in FIGS. 1, 8, and 11, the volatile stick-shaped cosmetic material feeding container 100 of the present embodiment has an airtight cap 7 for sealing the volatile stick-shaped cosmetic material 6 accommodated in the front tube 1. Is detachably attached to the front portion of the front tube 1. Further, an inner lid 7a is provided inside the cap 7 so as to cover the front end of the front tube 1 and to be attached so as to be in close contact with the front end, thereby making it possible to keep the cosmetic 6 in a more sealed state. Has been. Here, the cap 7 and the inner lid 7a are separate members, but a structure corresponding to the inner lid 7a may be formed on the cap 7. Incidentally, the cap 7 and the inner lid 7a are formed of, for example, a polyester system that is not affected by volatile components.

  Next, an example of an assembly procedure of the volatile stick-shaped cosmetic material supply container 100 having such a configuration will be described with reference to FIGS. 1 to 3 and FIG. 11.

  First, the rotation stopper 2b is inserted from the rear end side of the main body cylinder 2a, and the rotation stopper 2b is engaged with the main body cylinder 2a so as not to move in the axial direction and to be able to rotate synchronously, thereby forming the container body 2. Next, the movable body 3 is inserted into the inner side of the ratchet-engaged spring member 4a and female screw member 4b, and is engaged with the female screw member 4b to screw the movable body 3 into a predetermined position. The female screw member 4b and the moving body 3 are accommodated in the container body 2.

  On the other hand, in the front tube 1, the piston body 5 is set in an accurate position in the axial direction (position in the initial state) while sticking the piston body 5 in the housing portion 1 a of the front tube 1 using a rod-like body or the like. Next, a cosmetic filling machine provided with a small-diameter nozzle capable of entering the housing portion 1a of the front tube 1 is prepared, and the nozzle is caused to enter the housing portion 1a from the opening 1c at the tip of the front tube 1. The molten cosmetic material (rod-shaped cosmetic material) is filled by direct injection while preventing air from entering. Then, the nozzle is gradually pulled out from the housing portion 1a, and the cosmetic material is cooled and solidified, so that the volatile sticky cosmetic material 6 that is tightly accommodated in the housing portion 1a is obtained. At this time, the cosmetic is also filled and formed in the concave portion 5c on the front side of the piston body 5.

  And the volatile stick-shaped cosmetics supply container 100 which can pay out the volatile stick-shaped cosmetics 6 by inserting the tip cylinder 1 which accommodated the volatile stick-shaped cosmetics 6 and the piston body 5 in the said container main body 2 inside. Is obtained.

  In the volatile stick-shaped cosmetic supply container 100 obtained in this way, the piston body 5 that is slidably inserted into the front tube 1 in a close contact state, and the moving body 3 on the rear side thereof. Are separated and disengaged, so that the melted cosmetic is applied to the opening 1c at the front end of the container in a state where only the piston body 5 is disposed at a predetermined position (initial position) in the front tube 1. The inside of the piston body 5 can be directly filled, and a fixed amount of cosmetic can be filled on the front side of the piston body 5 without being affected by the moving body 3 (without being influenced by the moving body 3). As a result, defective filling is eliminated and quality can be stabilized.

  In this assembly, the piston body 5 is also provided with a concave portion 5c having the same shape as the concave portion 5d on the front end surface thereof. It is possible to assemble and improve the assemblability.

  In addition, when the position of the moving body 3 is accurately located at a predetermined position (position in the initial state) or shifted to the rear side in the container main body 2, the leading tube 1 is inserted into the container main body 2. In this case, there is no problem because the piston body 5 is not pushed forward by the moving body 3. For example, even when the moving body 3 is shifted to the front side, the front tube 1 is inserted into the container body 2. The moving body 3 abuts on the piston body 5 and the spring portion 4aa of the spring member 4a contracts via the female screw member 4b, so that the moving body 3 moves rearward and is positioned at a predetermined position (position in the initial state). No problem.

  In the volatile stick-shaped cosmetic material supply container 100 having such a configuration, when the user relatively rotates the front tube 1 and the container body 2 in the feed direction, the front tube 1 and the female screw member 4b rotate synchronously, and the container The main body 2, the spring member 4a, and the moving body 3 rotate synchronously, whereby the screwing action of the female screw 4bb of the female screw member 4b and the male screw 3a of the moving body 3 works, and the moving body 3 advances in the feeding direction. Then, the tip 3c of the moving body 3 enters and contacts the recess 5d on the rear side of the piston body 5. When the piston body 5 and the moving body 3 are accurately positioned at a predetermined position (initial position), the tip 3c of the moving body 3 enters the concave portion 5d of the piston body 5 from the beginning and comes into contact therewith. Will be.

  And since the front-end | tip 3c of the moving body 3 approached and contacted the recessed part 5d of the rear side of the piston body 5 in this way, the volatile stick-shaped cosmetics 6 which are closely_contact | adhered in the front cylinder 1 and have big resistance are piston body. When extruding by the advance of 5, the piston body 5 advances straight without being twisted by the irregularities 5d and 3c, and the volatile sticky cosmetic 6 is extruded well.

  At this time, the piston body 5 has annular convex portions 5a and 5b that slide in close contact with the inside of the front tube 1 at positions spaced apart in the axial direction of the outer peripheral surface thereof. Due to the annular protrusions 5a and 5b, the piston body 5 advances straight without twisting, and the volatile sticky cosmetic 6 is pushed out better.

  And this volatile stick-shaped cosmetic 6 appears from the opening part 1c of the front-end | tip of the front tube 1, and is made into a use condition.

  Further, when the moving body 3 is further moved in the feeding direction, the screwed connection between the female screw 4bb and the male screw 3a is released, and the moving body 3 reaches the feeding limit (advance limit). However, even if the screw connection is released, the spring member 4a pushes up the female screw member 4b in the axial direction by the elastic force of the spring portion 4aa, and the female screw 4bb and the male screw 3a are immediately screwed back. Note that the protrusion 3d (see FIG. 6) extending in the axial direction of the moving body 3 and the ratchet protrusion 4ba engage with each other, and the moving body 3 is released before the screwed connection between the female screw 4bb and the male screw 3a is released. By engaging with the female screw member 4b so as to be able to rotate synchronously, it is also possible to set the moving body 3 to the delivery limit (advance limit).

  Further, for example, after the use of the volatile sticky cosmetic material 6 is finished, when the tip tube 1 is replaced with a new one containing the new volatile sticky cosmetic material 6, after removing the lead tube 1 from the container body 2, In a state where the female screw member 4b and the spring member 4a are free, the female screw member 4b and the moving body 3 are relatively rotated in the direction opposite to the feeding direction to move to the initial position as shown in FIGS. After returning 3, a new leading cylinder 1 may be inserted into the container body 2.

  According to such a volatile stick-shaped cosmetic feed container 100, the stick-shaped cosmetic is made into the stick-shaped cosmetic 6 containing the volatile oil for makeup, and the diameter thereof is a small diameter of 0.9 mm to 2.5 mm. Therefore, it is possible to draw thin lines such as those drawn with a brush or comb, to realize a thin container, and to spread the applied cosmetic with a smooth feeling of use. It is excellent in portability.

  Further, since the rotation stoppers 3b and 2bc constituting the feeding mechanism are respectively provided on the outer periphery of the rear end of the movable body 3 and the inner periphery of the container main body 2, the container can be further reduced in diameter.

  Further, since the volatile bar-shaped cosmetic material 6 is gradually fed out by the ratchet engagement and the thread pitch of the feeding is 0.25 mm to 1 mm and the number of threads is 1, the shape of the volatile bar-shaped cosmetic material 6 having a small diameter is obtained. You can pay out without breaking.

  Moreover, volatilization of the volatile sticky cosmetic material 6 can be reliably prevented by the airtight cap 7 attached to the tip of the front tube 1.

  FIG. 12 is a longitudinal sectional view showing an initial state of a volatile stick-shaped cosmetic material feeding container according to the second embodiment of the present invention.

  The volatile bar-shaped cosmetic material supply container 200 of the second embodiment is different from the volatile bar-shaped cosmetic material supply container 100 of the first embodiment in that the front tube 1 and the main body tube 2a are engaged with each other so as to be able to rotate synchronously. The main body cylinder 2a constituting the container main body 2 and the rotation stopper 2b are engaged with each other so as to be relatively rotatable, and the rotation stopper 2b is used as a container rear portion.

  That is, in the illustrated volatile stick-shaped cosmetic material feeding container 200, the rotation body 2b rotates relative to the front tube 1 and the main body tube 2a, so that the moving body 3 moves in the feeding direction. Accordingly, the piston body 5 also moves, so that the volatile sticky cosmetic material 6 is fed out from the opening 1c of the front tube 1.

  As a configuration of such a volatile stick-shaped cosmetic feed container 200, compared with the configuration of the volatile stick-shaped cosmetic feed container 100 of the first embodiment, the outer periphery of the rear portion inserted into the main body cylinder 2a of the front tube 1. A protrusion (not shown) that enables synchronous rotation with the main body cylinder 2a in the axial direction, and a protrusion provided on the outer peripheral surface of the rear part of the front cylinder 1 in the axial direction of the inner peripheral surface of the front part of the main body cylinder 2a; A protrusion (not shown) for engagement is provided. In addition, as long as the front tube 1 and the main body tube 2a operate so as to be able to rotate synchronously, another configuration that can obtain the same effect instead of the above-described protrusion may be used.

  Furthermore, as a configuration of the volatile stick-shaped cosmetic material feeding container 200, as compared with the configuration of the volatile stick-shaped cosmetic material supply container 100 of the first embodiment, the protrusion 2ac is provided on the inner peripheral surface of the rear portion of the main body cylinder 2a. In addition, the protrusion 2bb is not provided on the outer peripheral surface of the rotation stopper 2b. Further, as shown in the figure, the rotation stopper 2b of the volatile stick-shaped cosmetic feed container 200 has a shape in which the rear portion protrudes in the axial direction as compared with the rotation stopper 2b of the volatile stick-shaped cosmetic supply container 100. In order to make it easy to grip the rotation stopper 2b, such a shape is adopted.

  Further, as described above, since the rotation stopper 2b rotates relative to the front tube 1 and the main body tube 2a, the spring member 4a and the female screw member 4b rotate synchronously while being engaged. If the ratchet function is provided, the rear end of the spring member 4a and the front end of the rotation stopper 2b may be configured to be able to engage with the ratchet.

  The volatile bar-shaped cosmetic material supply container 200 having such a configuration is the same as the volatile bar-shaped cosmetic material supply container 100 in other configurations, and thus has the same functions and effects.

  FIG. 13: is a longitudinal cross-sectional view which shows the volatile stick-shaped cosmetic material delivery container which concerns on 3rd Embodiment of this invention.

  The difference between the volatile stick cosmetic delivery container 300 of the third embodiment and the volatile stick cosmetic delivery container 100 of the first embodiment or the volatile stick cosmetic delivery container 200 of the second embodiment is that the container body. This is that a grip portion 9 for gripping the chip 8 is provided on the rear end side of the second rotation stopper 2b. Here, the chip 8 is used for blurring or spreading the cosmetic 6 applied to the object.

  And the other structure is the same as that of the volatile stick-shaped cosmetic material delivery container 100 or the volatile stick-shaped cosmetic material delivery container 200. Therefore, the effect | action and effect to show | play are the same. In addition, in FIG. 13, the structure which added the holding | grip part 9 and the chip | tip 8 to the volatile stick-shaped cosmetic material delivery container 100 as an example is shown.
