Description

The present disclosure relates to a cosmetic container in which a cosmetic is housed.

BACKGROUND ART Various types of cosmetic containers for storing cosmetics have been known. Japanese Unexamined Patent Application Publication No. 2003-204823 describes a stick-like object dispensing tool for dispensing a stick-like object as a cosmetic. The stick-like object feeder feeds out stick-like objects such as eyeliner. The rod-shaped object feeding tool includes a cylindrical front shaft and a bottomed cylindrical rear shaft, and the front shaft is connected to the rear shaft so as to be relatively rotatable. Cosmetics are stored inside the tip.

Inside the rear shaft, there is a piston rod with a male screw that pushes out the rod inside the front shaft, a cylindrical driver that has a female screw on the inside that the male screw of the piston rod is screwed into, and a piston rod for the front shaft. A detent ring is provided to prevent rotation of the rotor. When the front shaft and rear shaft rotate relative to each other in one direction, the driver rotates in synchronization with the rear shaft, and the screwing action between the female screw of the driver and the male screw of the piston rod works, causing the piston rod to move forward relative to the driver. . As the piston rod moves forward, a rod-like object is discharged from an opening formed at the tip of the tip shaft, and the rod-like object is ready for use. Further, when the front shaft and the rear shaft rotate relative to each other in a direction opposite to the one direction described above, the above-mentioned screwing action works and the piston rod retreats.

An inner cylinder is provided inside the tip shaft, and the rod-shaped object is housed inside the inner cylinder. The inner cylinder is movable inside the tip shaft. The inner cylinder is press-fitted into the advancing piston rod, and at this time the piston rod enters the inner cylinder. When the piston rod retreats, the inner cylinder and the rod-like object also retreat together with the piston rod. As the material for the inner cylinder, POM (polyacetal), PC (polycarbonate), or the like is used.

JP2003-204823A

By the way, the cosmetics stored inside the tip cylinder are required to be airtight. Some cosmetics have a low viscosity and some have a small diameter, and these cosmetics are particularly required to be airtight. In recent years, highly volatile cosmetics have been increasingly used. Therefore, it is required to ensure airtightness and suppress volatilization of cosmetics.

An object of the present disclosure is to provide a cosmetic container that can ensure airtightness and suppress volatilization of cosmetics.

The cosmetic container according to the present disclosure includes a storage area for storing cosmetics, a front tube having an opening through which the cosmetic stored in the storage area is exposed, and a container embedded in the front tube so as to surround the storage area of the front tube. The pipe material is made of a gas-impermeable material having lower gas permeability than the tip tube, the tip tube is made of a resin material, and the tip tube is made of a resin material. The second resin part includes a first resin part located outside the pipe material and a second resin part located inside the pipe material, and the second resin part has an enlarged diameter part, and the enlarged diameter part has a rear end of the pipe material. The department is getting involved .

In this cosmetic container, a pipe material is embedded in a tip cylinder provided with a storage area for storing cosmetics. The pipe material is embedded in the front tube so as to surround a storage area in which cosmetics are stored. The material of the pipe material is a gas-impermeable material that has lower gas permeability than that of the leading tube. Therefore, since it is possible to make it difficult for gas to pass through the pipe material, it is possible to suppress the permeation of gas into the cosmetic storage area located inside the pipe material. Therefore, airtightness can be ensured by the pipe material embedded in the front tube and arranged so as to surround the storage area, and it is also possible to suppress volatilization of the cosmetic stored in the storage area.

The cosmetic container described above includes a container main body that is relatively rotatably engaged with the front tube, a push rod that is arranged inside the container main body and has a male screw formed on its outer periphery, and a push rod that is arranged inside the container main body. The cage is equipped with a cylindrical female screw member having a female screw formed on the inner periphery to be screwed together with the male screw of the push rod, and when the container main body rotates relative to the front tube, the male screw and the female screw screw together. The cosmetic may be pushed out of the opening by the push rod as the push rod moves relative to the female screw member. In this case, due to the relative rotation between the container body and the tip tube, the screwing action of the male screw and the female screw acts to move the push rod, and the cosmetic is dispensed by the push rod. Therefore, even if the cosmetic container is equipped with a feeding mechanism that feeds out the cosmetic, the pipe material made of the gas-impermeable material can ensure airtightness and suppress volatilization of the cosmetic.

The cosmetic container described above may include a piston located in the accommodation area of the tip cylinder on the opposite side of the cosmetic opening, and the push rod may push out the cosmetic through the piston. In this case, since the push rod pushes out the cosmetic through the piston, it is possible to avoid the cosmetic from adhering to the push rod. Further, since the piston located on the opposite side of the cosmetic opening can ensure airtightness on the opposite side of the opening, volatilization of the cosmetic can be suppressed more reliably.

Since the second resin part is provided inside the pipe material, the cosmetic comes into contact with the second resin part instead of the pipe material. Therefore, by interposing the second resin part between the pipe material and the cosmetic, the cosmetic can be protected by the second resin part. The second resin part may be made of a resin material having lower gas permeability than the first resin part.

According to the present disclosure, it is possible to ensure airtightness and suppress volatilization of cosmetics.

Hereinafter, embodiments of a cosmetic container according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description will be omitted as appropriate.

FIG. 1 is a side view of the cosmetic container according to the present embodiment. FIG. 2 is a side view showing the cosmetic container of FIG. 1 with the cap removed. FIG. 3 is a cross-sectional view taken along line AA in FIG. As shown in FIGS. 1 to 3, the cosmetic container 100 according to the present embodiment has a rod shape extending along the axial direction L. As shown in FIGS.

The cosmetic container 100 includes a cap 1 and a container body 2 as external configurations. The cosmetic container 100 is, for example, a pencil that dispenses (pushes out) the cosmetic M stored in the tip tube 3 located inside the cap 1 by a user's operation. The front tube 3 has an opening 3b through which the dispensed cosmetic M projects.

For example, the cap 1 is attached to the front barrel 3. A front tube 3 that engages with the container body 2 in the axial direction L is housed inside the cap 1 . The container main body 2 is connected to the rear side of the front tube 3 and engages with the front tube 3 so as to be relatively rotatable. The front cylinder 3 is made of PBT (polybutylene terephthalate), for example.

In the present disclosure, the "axial direction" refers to the direction in which the axis of the front tube of the cosmetic container extends, and the "axial direction" corresponds to the longitudinal direction of the cosmetic container, for example. Hereinafter, the direction in which the cap 1 is provided when viewed from the container body 2 will be referred to as "front", and the direction in which the container body 2 is provided as viewed from the cap 1 will be referred to as "rear". However, these directions are for convenience of explanation and are not intended to limit the direction.

The cosmetic M is, for example, a lip liner, lipstick, lip gloss, eyebrow, eyeliner, beauty stick, or concealer. The cosmetic M may be a very soft (eg, semi-solid, soft-solid, soft, jelly, mousse, or a paste containing these) rod-like products. The cosmetic M may contain a cosmetic volatile oil. Furthermore, the cosmetic M can be a thin rod-shaped article with an outer diameter of 1.5 cm or less, a general rod-shaped article with an outer diameter of 1.5 mm or more and 3.0 mm or less, or a large diameter rod-shaped article with an outer diameter of 4.0 mm or more. It may also be a rod-shaped object. Moreover, the cross-sectional shape when the cosmetic material M is cut along a plane perpendicular to the longitudinal direction of the cosmetic material M may be a circular shape, an elliptical shape, or a polygonal shape, and is not particularly limited.

The cap 1 includes an outer cap 11 exposed to the outside of the cosmetic container 100 and an inner cap 12 that is separate from the outer cap 11 and located inside the outer cap 11. For example, the inner cap 12 closes the opening 3b of the front tube 3 when the front tube 3 is inserted. As an example, the outer cap 11 is made of ABS (acrylonitrile butadiene styrene) resin. The inner cap 12 is made of an elastic material, for example, and is made of TPEE (polyester thermoplastic elastomer), for example.

Inside the container body 2, there is a cylindrical female screw member 4 having a female screw 4b inside, a push rod 5 having a male screw 5b that screws with the female screw 4b of the female screw member 4, the push rod 5, and cosmetics. A piston 6 which is interposed between M and pushes the cosmetic M forward as the push rod 5 moves forward, and a cylindrical ratchet member 7 located behind the female screw member 4 are provided.

The female thread 4b and the male thread 5b constitute, for example, a threaded part T of the cosmetic container 100, and the push rod 5 moves forward by the threaded action of the threaded part T. The female screw member 4 is made of, for example, POM (polyacetal). The female screw member 4 includes a cylindrical portion 4c having a female screw 4b. An insertion region 4f into which the push rod 5 is inserted is formed on the rear side of the cylindrical portion 4c. For example, the inner diameter of the insertion region 4f is larger than the inner diameter of the portion of the cylindrical portion 4c where the female screw 4b is provided.

The female screw member 4 has a plurality of convex portions 4d extending in the axial direction L on the outer peripheral surface of the cylindrical portion 4c. For example, a plurality of convex portions 4d are arranged along the circumferential direction of the female screw member 4. The convex portion 4d is a portion that engages with the front cylinder 3 in the circumferential direction when the cylinder portion 4c is inserted into the inside of the front cylinder 3 from the rear side.

The push rod 5 has a rod shape. The push rod 5 is made of, for example, POM. The push rod 5 includes a male screw 5b, an insertion portion 5c located on the rear side of the male screw 5b and inserted inside the female screw member 4 and the ratchet member 7, and a collar portion 5d facing the rear end of the ratchet member 7. Equipped with. The male screw 5b is provided, for example, from the front end of the push rod 5 to the rear side of the push rod 5. The outer diameter of the insertion portion 5c is larger than the outer diameter of the male screw 5b, and the outer diameter of the collar portion 5d is larger than the outer diameter of the insertion portion 5c. The flange 5d engages with a recess 2d formed on the inner surface of the container body 2 in the circumferential direction. Thereby, the push rod 5 engages with the container body 2 so as to be movable in the axial direction and rotatable in synchronization.

The piston 6 is provided on the rear side of the cosmetic M inside the front tube 3. As an example, the piston 6 is made of TPEE. For example, the piston 6 has a first recess 6b recessed rearward at the front end and a second recess 6c recessed forward at the rear end. The piston 6 is pushed forward by the push rod 5 and causes the cosmetic M to protrude from the opening 3b of the front tube 3.

The ratchet member 7 has, for example, a cylindrical shape having a spring portion 7c in which a slit 7b is formed in the center portion of the ratchet member 7 in the axial direction L. The ratchet member 7 includes a front cylinder part 7d with which the female screw member 4 engages, a spring part 7c, and a rear cylinder part 7f with which the container body 2 engages. The front cylinder portion 7d has a plurality of protrusions 7g extending in the axial direction L on the outer peripheral surface of the ratchet member 7, and the plurality of protrusions 7g are arranged so as to line up along the circumferential direction of the ratchet member 7. The protrusion 7g is a portion that engages with the knurling 2b formed on the inner surface of the container body 2 in the circumferential direction.

The ratchet member 7 constitutes a ratchet mechanism R together with the female screw member 4, for example. For example, the ratchet mechanism R allows relative rotation between the tip tube 3 and the container body 2 in only one direction (e.g., clockwise), and restricts relative rotation in the opposite direction (e.g., counterclockwise). .

The spring portion 7c is a portion that constitutes a resin spring that can be expanded and contracted in the axial direction L. The spring part 7c has a main body part 7h and a slit 7b that runs along the circumferential surface of the main body part 7h and communicates between the inside and outside of the main body part 7h. The rear cylinder portion 7f has a plurality of protrusions 7j extending in the axial direction L on the outer peripheral surface of the ratchet member 7. The protrusion 7j is a portion that engages with the inner surface of the container body 2 in the circumferential direction, similar to the protrusion 7g described above.

The procedure for using the above cosmetic container 100 will be explained. First, the cap 1 is removed from the front tube 3, and the container body 2 and the front tube 3 are relatively rotated in one direction. When the container body 2 and the front tube 3 are rotated relative to each other in one direction, the container body 2, the push rod 5, and the ratchet member 7 rotate synchronously, and the front tube 3 and the female screw member 4 rotate synchronously, so that the threaded portion T is rotated. The push rod 5 moves forward with respect to the female screw member 4 due to the screwing action.

As shown in FIG. 4, as the push rod 5 moves forward, the push rod 5 pushes the cosmetic M inside the front tube 3 forward, and the cosmetic M is fed out. In this embodiment, the container body 2, the tip tube 3, the female screw member 4, the push rod 5, and the ratchet member 7 function as a mechanism for feeding out the cosmetic container 100. The cosmetic M protrudes forward from the front tube 3 and is applied to an area to be applied (for example, the user's skin), so that the cosmetic M is ready for use. FIG. 4 shows a state in which the push rod 5 has moved to its forward limit.

When the push rod 5 reaches its forward limit, for example, the flange 5d of the push rod 5 comes into contact with the rear end of the ratchet member 7, and the piston 6 approaches the opening 3b of the front cylinder 3. Furthermore, the ratchet mechanism R restricts the relative rotation of the container body 2 and the front tube 3 in the opposite direction to the one direction. Therefore, in this embodiment, the push rod 5 does not retreat until the cosmetic M is used.

Next, details of the front tube 3 will be explained with reference to FIG. FIG. 5 is an enlarged cross-sectional view of the front tube 3 in FIG. 4. As shown in FIG. 5, the cosmetic container 100 includes a pipe material 8 embedded in the tip tube 3. In this disclosure, "embedded" refers to when something is completely surrounded by another thing and cannot be seen from the outside, and when something is fixed to the inner surface of another thing so that it is visible from the outside. This includes both cases where it is no longer possible to do so. That is, "embedded" includes a state in which something is fixed to the inner surface of another and exposed on the inner surface. The pipe material 8 has, for example, a cylindrical shape. The front tube 3 has an opening 3b through which the cosmetic material M protrudes, and a storage area 3c for accommodating the cosmetic material M.

The storage area 3c has, for example, a cylindrical shape, and the cosmetic M, the piston 6, and the male screw 5b of the push rod 5 are provided inside the storage area 3c. The front cylinder 3 includes a first resin part 3A located on the radially outer side of the front cylinder 3, and a second resin part 3B located on the radially inner side of the first resin part 3A and defining a housing area 3c. .

The first resin portion 3A constitutes the outer surface of the front tube 3. The first resin portion 3A has a tapered surface 3d that is inclined so that the diameter of the front cylinder 3 gradually decreases toward the opening 3b, a convex portion 3f on which the cap 1 (outer cap 11) is attached, and a convex portion 3f. It has a collar portion 3g located at the rear and an insertion portion 3h located at the rear side of the collar portion 3g.

When the cap 1 is attached to the front tube 3, a portion in front of the flange 3g is accommodated in the cap 1, and the flange 3g is exposed to the outside of the cosmetic container 100. The outer diameter of the insertion portion 3h is smaller than the outer diameter of the flange portion 3g, and the insertion portion 3h enters the inside of the container body 2 and engages with the container body 2 in the axial direction L. Thereby, the front cylinder 3 engages with the container body 2 so as to be immovable in the axial direction and capable of relative rotation.

The first resin part 3A and the second resin part 3B are integrally molded, for example, by two-color molding. As an example, the material of the first resin part 3A and the material of the second resin part 3B are different from each other. The materials of the first resin part 3A and the second resin part 3B are PBT (polybutylene terephthalate), PET (polyethylene terephthalate), ABS (acrylonitrile butadiene styrene), PEN (polyethylene naphthalate), or PP (polypropylene). be. For example, the first resin part 3A is made of a resin material with higher fluidity than the second resin part 3B, and the second resin part 3B has lower gas permeability (higher gas barrier property) than the first resin part 3A. ) Made of resin material.

In the present disclosure, "gas permeability" refers to the ease with which gas permeates through something, and is also referred to as gas permeability or gas permeability. Gas permeability includes, for example, nitrogen permeability and oxygen permeability. "Gas barrier property" is an index that indicates how difficult it is for gas to pass through something, and is also referred to as gas impermeability.

The pipe material 8 is made of a material having lower gas permeability (higher gas barrier properties) than the first resin part 3A and the second resin part 3B. The pipe material 8 is made of, for example, a gas-impermeable material that has lower gas permeability than resin. The term "gas impermeable material" refers to a material that has higher gas impermeability (higher gas barrier properties) than a certain thing (for example, the front tube 3).

The pipe material 8 is made of metal or glass, for example. As an example, the material of the pipe material 8 may be stainless steel (SUS), iron, brass, or aluminum. The pipe material 8 is interposed, for example, between the first resin part 3A and the second resin part 3B, and is embedded in the radially outer side of the front cylinder 3 than the accommodation area 3c of the front cylinder 3. The pipe material 8 is embedded in the front tube 3 so as to surround the accommodation area 3c from the outside in the radial direction.

The second resin portion 3B has, for example, an enlarged diameter portion 3j at the rear end, and the rear end portion 8b of the pipe material 8 protrudes from the enlarged diameter portion 3j. Note that the term "rear end" refers to a certain region including the rear end, and the term "front end" refers to a certain region including the front end. The enlarged diameter portion 3j is provided on the radially inner side of the convex portion 3f and the collar portion 3g of the first resin portion 3A. When the second resin part 3B is made of a material with higher gas barrier properties than the first resin part 3A, the enlarged diameter part 3j of the second resin part 3B increases the airtightness of the rear side of the accommodation area 3c. I can do it.

The front end 3k of the second resin part 3B and the front end 8c of the pipe material 8 are located on the radially inner side of the first resin part 3A. That is, the front end portion 3k and the front end portion 8c are located at the rear of the opening 3b of the front tube 3. For example, the front end 3k protrudes more toward the opening 3b than the front end 8c. The front end portion 3k has a tapered portion 3m that slopes so that the diameter of the front tube 3 increases toward the rear, and the front end portion 8c contacts the surface of the tapered portion 3m on the opposite side (rear side) to the opening 3b. . Note that even when the push rod 5 reaches its forward limit, the piston 6 remains in the accommodation area 3c on the radially inner side of the pipe material 8 and the second resin portion 3B, so that the airtightness of the front side of the accommodation area 3c can be improved.

Next, the effects of the cosmetic container 100 according to this embodiment will be explained in detail. In the cosmetic container 100, a pipe material 8 is embedded in a tip tube 3 having a storage area 3c for storing a cosmetic M. The pipe material 8 is embedded in the front tube 3 so as to surround the storage area 3c in which the cosmetic material M is stored. The material of the pipe material 8 is a gas-impermeable material having lower gas permeability than that of the front tube 3. Therefore, since it is possible to make it difficult for gas to pass through the pipe material 8, it is possible to suppress the permeation of gas into the storage area 3c of the cosmetic M located inside the pipe material 8. Therefore, airtightness can be ensured by the pipe material 8 embedded in the front tube 3 and arranged so as to surround the storage area 3c, and the volatilization of the cosmetic material M stored in the storage area 3c can be suppressed. .

As shown in FIGS. 3 and 4, the cosmetic container 100 according to the present embodiment includes a container body 2 that engages with the front tube 3 in a relatively rotatable manner, and a container body 2 that is disposed inside the container body 2. A push rod 5 having a male screw 5b formed therein, and a cylindrical female screw member 4 disposed inside the container body 2 and having a female screw 4b formed on its inner periphery to be screwed together with the male screw 5b of the push rod 5. and. When the front cylinder 3 rotates relative to the container body 2, the screwing action of the male screw 5b and the female screw 4b (threaded portion T) works, and the push rod 5 moves relative to the female screw member 4, so that the push rod 5, the cosmetic M is pushed out from the opening 3b. That is, due to the relative rotation between the container body 2 and the tip tube 3, the screwing action between the male screw 5b and the female screw 4b is activated, the push rod 5 is moved, and the cosmetic M is fed out by the push rod 5. Therefore, even if the cosmetic container 100 is equipped with a dispensing mechanism for dispensing the cosmetic M, the pipe member 8 made of a gas-impermeable material can ensure airtightness and suppress volatilization of the cosmetic M.

The cosmetic container 100 according to the present embodiment includes a piston 6 located in the storage area 3c of the front tube 3 on the opposite side of the opening 3b for the cosmetic M, and the push rod 5 is inserted into the cosmetic M through the piston 6. Push out. Therefore, since the push rod 5 pushes out the cosmetic M via the piston 6, it is possible to prevent the cosmetic M from adhering to the push rod 5. Moreover, the piston 6 located on the opposite side of the opening 3b of the cosmetic M can ensure airtightness on the opposite side of the opening 3b. Specifically, when the cap 1 is attached to the front tube 3, the piston 6, the pipe material 8, and the cap 1 (inner cap 12) ensure airtightness of the cosmetic M. Therefore, volatilization of the cosmetic M can be suppressed more reliably.

In the cosmetic container 100 according to the present embodiment, the tip tube 3 is made of a resin material, and the tip tube 3 has a first resin part 3A located on the outside of the pipe material 8 and a first resin part 3A located on the outside of the pipe material 8. and a second resin portion 3B located therein. Therefore, since the second resin part 3B is provided inside the pipe material 8, the cosmetic M comes into contact with the second resin part 3B instead of the pipe material 8. Therefore, by interposing the second resin part 3B between the pipe material 8 and the cosmetic M, the cosmetic M can be protected by the second resin part 3B.

The embodiments of the cosmetic container according to the present disclosure have been described above. However, the present invention is not limited to the embodiments described above, and may be further modified without changing the gist of each claim. That is, the shape, size, number, material, and arrangement of each component constituting the cosmetic container can be changed as appropriate without departing from the above gist.

For example, in the embodiments described above, the pipe material 8 is made of metal or glass. However, the material of the pipe material embedded in the front tube 3 may be other than metal or glass. For example, the pipe material may be made of a resin material that has higher gas barrier properties than the leading tube 3.

Furthermore, in the embodiment described above, an example has been described in which the pipe material 8 is embedded in the front tube 3 so that the pipe material 8 is interposed between the first resin part 3A and the second resin part 3B. However, instead of the pipe material 8, the cosmetic container may include a pipe material exposed on the inner surface of the second resin part 3B. In this case, the pipe material is embedded in the front tube 3 in a manner fixed to the inner surface of the second resin portion 3B.

Furthermore, in the embodiment described above, an example was described in which the material of the first resin part 3A and the material of the second resin part 3B are different from each other. However, the material of the first resin part 3A and the material of the second resin part 3B may be the same. Furthermore, in the above-described embodiment, an example has been described in which the first resin part 3A and the second resin part 3B are integrally molded by two-color molding. However, the first resin part and the second resin part do not have to be integrally molded by two-color molding, for example, the first resin part and the second resin part are physically fixed and integrally formed. You can leave it there. Furthermore, the leading tube may not have either the first resin part or the second resin part.

Moreover, in the embodiment described above, the cosmetic container 100 including the piston 6 has been described. However, a cosmetic container without the piston 6 may also be used. Moreover, in the above-mentioned embodiment, the feeding mechanism (container body 2, tip tube 3, female screw member 4, push rod 5, and ratchet member 7) that feeds out the cosmetic M by relative rotation of the container body 2 and the tip tube 3 The cosmetic container 100 is exemplified. However, the configuration of the cosmetic container delivery mechanism is not limited to this example and can be modified as appropriate. Furthermore, the cosmetic container does not need to have a feeding mechanism for feeding out the cosmetic, and for example, may be provided with a knock-type pushing mechanism or the like in place of the feeding mechanism.
