Description

  The present invention relates to a cosmetic container obtained by feeding out a solid cosmetic such as an eyebrow, an eyeliner, an eye shadow, and a lip liner, in particular, a core cosmetic that is thin and soft and easy to break.

  Conventionally, solid cosmetics such as eyebrows, eyeliners, eyeshadows, and lip liners, especially cosmetic containers made by feeding core cosmetics that are soft and easy to break, are rotatably fitted to the shaft cylinder. A pipe for melting and filling and solidifying the cosmetic inside is inserted in a hermetic manner in the tip shaft to be worn, and a sliding shaft to be inserted from the rear end opening of the pipe is inserted into the shaft cylinder via a stop piece and a screw piece. There is one that advances by rotation and extrudes the cosmetic (see Patent Document 1).

  By the way, when the pipe is cut into a predetermined size in the manufacturing process, the overall length of the pipe can be long or short within a tolerance range. Therefore, in the design of the cosmetic container, it is necessary to consider the largest dimension of the overall length of the pipe within this tolerance range. That is, in the manufacturing process of the cosmetic container, especially when the total length of the pipe is short within the tolerance range, it is not securely fixed by the rotation piece and the screw piece in the front shaft, A gap is generated between the two. When the cosmetic material in the pipe is pushed out from the front shaft in a state where a gap is generated between the front shaft inner tip and the pipe front end, one of the cosmetics is the front shaft inner tip and the other is the pipe. It is in the state of a doubly supported beam by being supported by the tip. As a result, if a strong impact is applied to the cosmetic container due to dropping or the like, an excessive load is applied to the cosmetic that is in the state of a cantilever at the tip end of the front shaft and the tip of the pipe, and there is a risk of breakage. is there. Therefore, in order to prevent such breakage of the cosmetic, the design of the cosmetic container is based on the short pipe overall length within the tolerance range.

  On the other hand, in the case of a pipe having a long pipe length within the tolerance range, if the design of the cosmetic container is based on a pipe having a short pipe length, the pipe having the long pipe length will interfere with the stop piece or the screw piece. Therefore, there is a possibility that the pipe cannot be securely fixed in the front shaft.

No. 7-36580

  The problem to be solved by the present invention is that, particularly in a pipe having a long pipe length within a tolerance range, the pipe cannot be fixed securely in the front shaft due to interference between the stop piece and the screw piece.

As the first feature,
A core cylinder that is fitted to each other so as to be rotatable, and in which a holding hole having an opening with a tip communicating with the outside is disposed, and a shaft cylinder in which a knurl is engraved in the longitudinal direction on the inner peripheral surface And consists of
In the holding hole of the core cylinder, a pipe formed by abutting the tip with the inner peripheral step of the opening and filling and solidifying the cosmetic is fixed by a screw piece that is non-rotatably attached to the core cylinder. And
In the shaft cylinder, an engagement body is formed which engages with a knurled carved on the inner peripheral surface of the shaft cylinder at the rear end and rotates integrally, and is slidable in the longitudinal direction of the shaft cylinder. Is inserted with a push rod screwed with a male thread,
The push rod has a male screw portion and a screw piece that are screwed on the outer peripheral surface of the push rod so that the tip of the push rod comes into contact with and pushes out the rear end of the cosmetic that is filled and solidified inside the pipe held by the screw piece. And threading through the inside of the screw piece,
A female screw that is threadedly engaged with a male screw portion that is threaded on the outer peripheral surface of the push rod on the inner peripheral surface of the through hole, and a pipe holding portion that holds the pipe on one side and the other through the through hole. A screw part formed by screwing the part and a flexible part that can be elastically expanded and contracted in the penetration direction of the through hole therebetween are integrally formed.

For this reason, even if the pipe has a long pipe length within the tolerance range, when the pipe is fixed in the holding hole of the core cylinder with the screw piece, if the pressure is applied to the screw piece, the flexible portion of the screw piece Since the pipe contracts elastically in the through direction of the through hole to absorb the excess pipe, the screw piece is attached inside the core tube. As a result, it is possible to securely hold a pipe having a long overall pipe length within a tolerance range in the core cylinder while bringing the pipe tip into contact with the inner peripheral step of the opening at the tip of the holding hole inside the core cylinder. It is.

Furthermore, as the second feature, based on the first feature,
In the flexible portion of the threaded piece, it is made by forming a slit so as to be stretchable in the penetrating direction of the through hole.

Therefore, in the flexible part of the screw piece, the screw piece can be elastically expanded and contracted in the penetration direction of the through hole by bending the slit formed in the flexible part. That is, as described above, even when the pipe has a long pipe length within the tolerance range, when attaching the pipe while holding the pipe in the holding hole of the core cylinder with the screw piece, when pressure is applied to the screw piece, Since the slit in the flexible part of the screw piece is bent and the flexible part of the screw piece is elastically contracted in the penetration direction of the through hole to absorb the excess portion of the pipe, the screw piece is attached inside the core tube. . As a result, it is possible to securely hold a pipe having a long overall pipe length within a tolerance range in the core cylinder while bringing the pipe tip into contact with the inner peripheral step of the opening at the tip of the holding hole inside the core cylinder. It is.

Here, as the third feature, based on the first feature,
The slit formed to make the flexible part of the screw piece elastically extendable in the direction of attaching the screw piece has a pair of slits arranged so as to face each other in the cross-sectional direction of the through hole in the flexible part. Some of them are arranged in parallel along the direction while shifting their positions, and others are arranged in a spiral shape over the entire circumference of the flexible part. As a result, the flexible portion is bent by the slit, and the screw piece can be expanded and contracted in the through direction of the through hole .

As a fourth feature, based on the first, second, or third feature,
The core cylinder that forms the cosmetic container together with the shaft cylinder is composed of a core cylinder cap and a core cylinder main body that are provided with an opening at the tip that can be separated from each other.

  Therefore, the pipe attached by the screw piece in the core cylinder is exposed by removing the core cylinder cap that forms the core cylinder. As a result, after the cosmetic filled and solidified in the pipe is used up, the pipe can be removed and replaced with a new pipe filled and solidified with the cosmetic.

As a fifth feature, based on the first, second, third or fourth feature,
In order to ensure the sealing inside the core tube, the cap is mounted, or the cap is mounted with an inner cap, and the cap is mounted after an elastic O-ring is mounted on the outer peripheral surface of the core tube or the shaft tube. Or, a cap for installing an inner cap is attached.

  Here, in the cosmetic container, the opening of the core cylinder constituting the cosmetic container is open, but depending on the material of the cosmetic that is filled and solidified inside the pipe, the volatilization of the solvent of the cosmetic is prevented. A cap may be attached as much as possible. Furthermore, even if a cap is to be attached, an inner cap that seals the opening at the tip of the core tube is provided in the cap or the inner peripheral surface of the opening of the cap to enhance the sealing inside the cap. An O-ring having elasticity may be attached to the outer peripheral surface of the core tube or the shaft tube so as to be in close contact with each other. As a result, when the cap is equipped with an inner cap, the opening at the tip of the core tube is directly sealed with the inner cap to ensure sealing, so that the solvent in the cosmetic can be prevented from volatilizing reliably. In the case where an O-ring is mounted on the outer peripheral surface of the core tube or the shaft tube so as to be in close contact with the inner peripheral surface of the opening, the O-ring is elastically and accurately deformed with respect to the inner peripheral surface of the opening of the cap. Sealability can be ensured (see FIGS. 11 and 12).

According to the present invention, even when the pipe has a long pipe length within the tolerance range in the manufacturing process of the pipe, the flexible portion of the screw piece expands and contracts elastically in the through direction of the through hole, and the excess portion of the pipe is absorbed and securely held. Since the product yield of the pipe can be increased and the cost can be reduced, the pipe itself can be easily replaced by splitting the core cylinder cap constituting the core cylinder from the core cylinder body, so that cosmetics can be used. The container has an excellent effect of allowing continuous use of the container and improving the economic efficiency.

A pipe with a long overall length that is generated within the tolerance range in the manufacturing process absorbs the excess of the pipe by allowing the flexible part of the screw piece to be held in the core tube to expand and contract in the direction of penetration of the through hole . Even if it is a cosmetic container designed based on a pipe having a short overall pipe length, it can be securely held in the holding hole of the core tube.

  FIG. 1 shows a cosmetic container 1 that is Embodiment 1 of the present invention. The cosmetic container 1 has a cap 2 that is detachable.

And this cap 2 seals the opening part 4a of the core cylinder 4 tip which comprises the cosmetics container 1 mentioned later, and a solvent will volatilize from the cosmetics 6 filled and solidified in the pipe 5 mentioned later. An inner cap 3 that prevents the inner cap 3 is provided on the inner peripheral surface by locking the locking collar 3a at the locking concave edge 2a (see FIG. 3). It comprises a core cylinder 4 provided with a holding hole 4b having an opening 4a whose tip communicates with the outside, and a shaft cylinder 7 formed by engraving knurls 7a in the longitudinal direction on the inner peripheral surface (FIG. 5). FIG. 6). Then, the fitting projection edge 4d of the core tube 4 and the fitting concave edge 7e of the shaft tube 7 are fitted so as to be rotatable with respect to each other so as to be rotatable.
In addition, in order to prevent the solvent contained in the cosmetic 6 from volatilizing and to ensure hermeticity, the opening 4a of the core tube 4 is directly formed by the inner cap 3 provided in the cap 2 as described above. In addition to the one to be sealed, an O-ring having elasticity may be mounted on the outer peripheral surface of the core tube 4 or the outer peripheral surface of the shaft tube 7, and may be adhered to the inner peripheral surface of the cap 2 with elasticity.

Here, in the holding hole 4 b of the core cylinder 4, the pipe 5 formed by abutting the tip with the inner peripheral step part 4 c of the opening 4 a and filling and solidifying the cosmetic 6 therein is connected to the core cylinder 4. Thus, the locking concave peripheral edge 4f and the locking protrusion peripheral edge 12a are locked to prevent advancement, and the notch 4e and the locking protrusion 12 are locked to be fixed so that they cannot be rotated. Is.
Further, in the shaft cylinder 7, the shaft cylinder 7 is engaged with the knurling 7 a which is engraved in the longitudinal direction on the inner peripheral surface of the shaft cylinder 7 at the rear end and rotates integrally with the shaft cylinder 7. A push rod 8 having a male threaded portion 8b screwed on the outer peripheral surface thereof is formed by inserting an engaging body 8a having a cross-shaped cross section that is slidable along the knurl 7a (see FIG. 7). .

Here, the screw piece 9 has a pipe holding portion 11 in which a through-hole 10 penetrates inside, and two ribs 11a, 11a formed by elastically holding the pipe 5 on the inner peripheral surface, and the other. Two locking protrusions 12 and 12 are provided so as to face the outer peripheral surface of the bottom portion, and a screw portion 13 is formed by screwing a female screw portion 13a on the inner peripheral surface of the through hole 10, and further, there is elasticity between them. The flexible portion 14 that can be expanded and contracted in the penetration direction of the through hole 10 is integrally formed. That is, in the flexible portion 14, a pair of slits 14 a and 14 a arranged so as to face each other in the cross-sectional direction of the through hole 10 is arranged in parallel in three pairs while shifting the position by 90 ° along the direction of the through hole 10. The slit 14a bends and can be expanded and contracted elastically in the mounting direction of the screw piece 9 (see FIG. 4).

  In addition, the screw piece is so arranged that the tip 8c of the push rod 8 is brought into contact with the rear end of the cosmetic 6 filled and solidified in the pipe 5 held by the screw piece 9 and is sealed and sealed by the O-ring 8d. The push rod 8 is passed through the through hole 10 of the screw piece 9 while screwing the female screw portion 13a of the screw portion 13 and the male screw portion 8b screwed on the outer peripheral surface of the push rod 8. .

  Since the cosmetic container 1 which is Example 1 of the present invention has the above-described configuration, when the cap 2 is attached to the cosmetic container 1 integrally, the inner peripheral surface of the opening 2b of the cap 2 The locking protrusion 2d disposed on the shaft 7 is fitted to the locking concave edge 7d on the outer peripheral surface of the opening 7b of the shaft tube 7, and the knurled 2c provided around the inner peripheral surface end of the shaft tube 7 Since the four protrusions 7c formed at intervals of 90 ° on the outer peripheral surface of the opening 7b mesh with each other, the cap 2 and the shaft cylinder 7 are integrated with each other and are not rotatable with respect to each other. As a result, for example, even if a rotational force is applied to the shaft cylinder 7, it does not rotate with respect to the cap 7, and the cosmetic 6 is not fed out from the opening 4 a of the core cylinder 4 constituting the cosmetic container 1. Is.

  Further, after the cap 2 is removed from the cosmetic container 1, the push rod 8 moves forward through the screw piece 9 by rotating the shaft tube 7 with the core tube 4 by hand, and the pipe holding portion 11 of the screw piece 9. Since the cosmetic material 6 filled and solidified inside the pipe 5 that is held in place is extruded, the cosmetic material is fed out from the opening 4 a at the tip of the core tube 4. That is, in the push rod 8 inserted into the shaft cylinder 7, the engaging body 8 a formed at the rear end meshes with the knurl 7 a carved in the longitudinal direction of the inner circumferential surface of the shaft tube 7, and the outer circumferential surface of the push rod 8. The male screw portion 8b on the front end side that is screwed to the inner cylinder 4 is screwed with a female screw portion 13a that is screwed to the inner peripheral surface of the through hole 10 of the screw piece 9 that is non-rotatably attached to the core cylinder 4. It is. Therefore, by rotating the shaft cylinder 7, the push bar 8 rotates together with the shaft cylinder 7, and the push bar 8 advances in the through hole 10 of the screw piece 9. As a result, the forward end 8c of the push bar 8 moving forward is extruded while the rear end of the cosmetic 6 filled and solidified inside the pipe 5 is sealed with an O-ring 8d, and the push bar 8 pushes the cosmetic 6 at the front end of the core tube 4. It is drawn out from the opening 4a.

Therefore, the screw piece 9 for holding the pipe 5 in the core cylinder 4 constituting the cosmetic container 1 according to the first embodiment of the present invention has the above-described configuration, so that the cosmetic 6 is filled and solidified therein. In the manufacturing process of the pipe 5 to be performed, when the pipe 5 having a long overall length generated within the tolerance range is held in the holding hole 4b of the core cylinder 4 by the screw piece 9, the following is performed. . That is, when a pressure is applied to the screw piece 9, the flexible portion 14 of the screw piece 9 is a pair of slits arranged so as to face each other in the cross-sectional direction of the through hole 10 formed in the flexible portion 14. 14a and 14a are arranged in parallel along the direction of the through-hole 10 while shifting their positions by 90 °, so that the pipe 5 is excessively contracted by being elastically contracted in the through- direction of the through-hole 10 by bending. Absorb. As a result, since the screw piece 9 can be attached to the core tube 4, the pipe 5 is held while the tip of the pipe 5 is brought into contact with the inner peripheral step 4c of the opening 4a at the tip of the holding hole 4b of the core tube 4. It is something that can be done.

  The cosmetic container (hereinafter not shown) which is the second embodiment of the present invention includes almost all of the configurations including the cosmetic container 1 of the first embodiment of the present invention and the mounting of the cap that houses the inner cap. Are common.

However, the configuration is different in the following points. That is, in a core cylinder that constitutes a cosmetic container together with a shaft cylinder, a screw piece 9 ′ in which a pipe for filling and solidifying cosmetic is fixed inside has a through hole 10 ′ inside, and the pipe on one side A pipe holding portion 11 'that holds the two ends, and two locking projections 12' and 12 'projecting on the other side so as to face the outer peripheral surface of the bottom, and a female screw portion 13a' is screwed on the inner peripheral surface of the through hole 10 ' and threaded portion 13 formed by 'further has an elastic flexible portion 14 stretchable become the through direction of the through-hole 10 between them' together are integrally formed, the movable flexure 14 ', through holes with elastic 10 is different from the screw piece 9 of the cosmetic container 1 of Example 1 in that a spiral slit 14a ′ is formed over the entire circumference of the flexible portion 14 ′ so as to be expandable and contractable in the through direction. Yes (see FIG. 8).

  Here, the cosmetic container according to the second embodiment of the present invention has almost the same configuration as that of the cosmetic container 1 according to the first embodiment. As in the case of the cosmetic container 1, the push rod with which the engaging body formed at the rear end engages advances along the knurl along the knurl by rotating the shaft tube. Since the end of the abuts against the rear end of the cosmetic in the pipe and is extruded while being sealed with an O-ring, the cosmetic is fed out from the opening at the front end of the core tube.

Therefore, since the screw piece 9 'for holding the pipe in the core cylinder constituting the cosmetic container according to the second embodiment of the present invention has the above-described configuration, the pipe for filling and solidifying the cosmetic inside is provided. In the manufacturing process, when a pipe having a long overall length that is generated within the tolerance range is held in the holding hole of the core cylinder by the screw piece 9 ′, it is as follows. That is, when the pressure is applied to the screw piece 9 ′, the flexible portion 14 ′ of the screw piece 9 ′ has elasticity due to the bending of the spiral slit 14a ′ formed in the flexible portion 14 ′. It contracts in the penetration direction of the through hole 10 and absorbs the excess of the pipe. As a result, since the screw piece 9 'can be attached to the core tube, the pipe can be held while the tip of the pipe is in contact with the inner peripheral step of the opening at the tip of the holding hole of the core tube. .

  In addition, since the slit 14a ′ formed in the flexible portion 14 ′ is formed in a spiral shape over the entire circumference of the flexible portion 14 ′, the flexible portion 14a ′ is more uniformly contracted. Is. As a result, it is more reliable while completely contacting without causing a gap between the tip of the pipe held in the holding hole in the core tube and the inner peripheral step of the opening at the tip of the holding hole of the core tube. It can be held.

  FIG. 9 shows a cosmetic container 1 ′ that is Embodiment 3 of the present invention. The cosmetic container 1 ′ according to the third embodiment of the present invention has the same configuration as that of the cosmetic container 1 according to the first embodiment of the present invention, including the mounting of the cap 2 that houses the inner cap 3. Is.

However, the configuration is different in the following points. That is, the core cylinder 4 ′ that constitutes the cosmetic container 1 ′ together with the shaft cylinder 7 includes a core cylinder cap 4g ′ having an opening 4a ′ at the tip and a core cylinder body 4j ′, both of which are core cylinder caps. The knurls 4h ′ and the projecting edges 4i ′ of 4g ′ mesh with the knurls 4k ′ of the core cylinder body 4j ′ and engage with the concave edges 4l ′, respectively, so that they can be divided and integrated.
The screw piece 9 used in the third embodiment of the present invention has a pair of slits 14a formed in the flexible portion 14 so as to face each other in the cross-sectional direction of the through hole 10 as in the first embodiment. In addition to three slits 14a, 14a arranged in parallel along the direction of the through-hole 10 while shifting their positions by 90 °, a spiral slit 14a ′ formed over the entire circumference of the flexible portion 14 ′ of the second embodiment. However, any flexible member may be used as long as it elastically expands and contracts in the penetrating direction of the through hole 10 in the flexible portions 14 and 14 '.

Here, the cosmetic container 1 ′ according to the third embodiment of the present invention has the same configuration as that of the cosmetic container 1 according to the first embodiment, and thus is similar to the cosmetic container 1 according to the first embodiment. In addition, when the cosmetic 6 is fed out from the pipe 5, the push rod 8 engaged with the engaging body 8a formed at the rear end is rotated by rotating the shaft cylinder as in the cosmetic container 1 of the first embodiment. Since the front end 8c of the push bar 8 that moves forward advances along the knurl 7a to the inner peripheral surface of the cylinder 7 and abuts against the rear end of the cosmetic 6 in the pipe 5, it is extruded while being sealed by the O-ring 8d. The cosmetic 6 is fed out from the opening 4a at the tip of the core cylinder 4 .

  And since core 4 'which comprises cosmetics container 1' which is the said Example 3 of this invention of the said application comprises the above structures, when the cosmetics 6 filled and solidified inside the pipe 5 are used up In this case, the core cylinder cap 4g ′ forming the core cylinder 4 ′ together with the core cylinder main body 4j ′ in a detachable manner is removed, and the core cylinder 4 ′ is held by the screw piece 9 (9 ′). The pipe 5 is exposed to the outside. As a result, the pipe 5 is taken out, and a new pipe 5 filled and solidified with the cosmetic 6 is inserted into the holding hole 4b ′ of the core cylinder 4 ′ and the core cylinder cap 4d ′ is inserted instead. It can be exchanged with.

  The cosmetic container of the present invention can be firmly fixed to the cosmetic container regardless of the length within the tolerance range generated in the pipe for filling and solidifying the cosmetic inside. The present invention can also be applied to a container to which the above is applied.
