Description

TECHNICAL FIELD The present invention relates to a stick-shaped cosmetic delivery container capable of delivering a stick-shaped cosmetic.

Conventionally, there has been a demand for a cosmetic container that draws a thin line, such as an eyeliner, to draw a thinner line. A stick-shaped cosmetic dispensing container is disclosed that can be extended to draw a fine line.

JP 2012-235885 A

However, there is a limit to the diameter of the stick-shaped cosmetic for drawing a thin line. Also, the size becomes smaller, which causes a problem that it becomes difficult to ensure the strength to withstand assembly and use.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a stick-shaped cosmetic delivery container in which it is possible to easily draw a line that is thinner than the original drawn line of the stick-shaped cosmetic in the container.

A stick-shaped cosmetic delivery container according to the present invention is a stick-shaped cosmetic delivery container that stores a stick-shaped cosmetic and delivers the stick-shaped cosmetic axially forward from an opening at a tip end thereof. , a front edge including the front end, a rear edge including the rear end, and a front edge forming a step between the front edge and the rear edge. an intermediate edge portion extending rearward from the portion and connected to the rear edge portion, wherein the cosmetic stick has a first application surface along the front edge portion and a second application surface along the rear edge portion; and a surface connecting the first coating surface and the second coating surface to form a step between the first coating surface and the second coating surface and along an intermediate edge. It is characterized by having

According to such a stick-shaped cosmetic delivery container, when the tip of the stick-shaped cosmetic is shaped along the opening edge of the tip of the container, the front edge including the front end is inside the front edge. A first coating surface can be formed along the trailing edge, a second coating surface can be formed along the trailing edge inside the trailing edge including the trailing edge, and a second coating surface can be formed along the trailing edge. A surface connecting the first coating surface and the second coating surface can be formed on the inner side of the intermediate edge forming a step therebetween. A stick-shaped cosmetic having these surfaces is fed out and protruded from the opening at the tip of the container to form a first application part having a first application surface on the tip surface and a second application part having a second application surface on the tip surface. When the first and second application portions are applied to the target portion, the sizes of the first and second application portions are each smaller than the original size of the stick-shaped cosmetic contained in the container, so that the stick-shaped cosmetic in the container. You can easily draw a thinner line than the original drawing line.

Here, the front side edge extends rearward from the front end while being inclined at a substantially constant angle with respect to the axial direction, and the rear side edge is inclined from the rear end so as to be substantially parallel to the front side edge. Extending forward, the intermediate edge preferably extends from the rear end of the front edge and joins the front edge of the rear edge. When such a configuration is adopted, the first and second coating surfaces are flat coating surfaces that are inclined at substantially the same angle. Thus, a line thinner than the original line of the stick-shaped cosmetic in the container can be easily drawn without changing the angle of the container.

Moreover, as a configuration that favorably exhibits the above effects, there is a configuration in which the cross-sectional shape of the stick-shaped cosmetic material is circular .

As described above, according to the present invention, it is possible to provide a stick-shaped cosmetic delivery container in which a line thinner than the original line of the stick-shaped cosmetic in the container can be easily drawn.

Here, a cap detachably attached to the front barrel 2 so as to cover the front barrel 2 is removed and not illustrated.

The container body 1 is configured in a long cylindrical shape with a bottom. On the inner peripheral surface of the container body 1, a long ridge 1a extending from the bottom toward the tip side is provided to move the moving body 3 in the rotating direction. are arranged in parallel along the circumferential direction at equal intervals. A plurality of ribs 3b provided along the circumferential direction at the rear end of the moving body 3 and extending short in the axial direction enter between the protrusions 1a, 1a, so that the moving body 3 is synchronized with the container body 1. It is mounted rotatably and axially movably.

The projection 1a has a degree of projection toward the axial center that gradually decreases toward the front in the axial direction. It is a stepped surface 1b for contacting the end surface. Further, on the inner peripheral surface of the container body 1 on the front side of the stepped surface 1b, a groove 1c between the ridges 1a extending in the axial direction is provided for engaging the ratchet spring member 4 in the rotational direction. A plurality of them are arranged side by side at equal intervals along the direction.

The ratchet spring member 4 has a substantially cylindrical shape, and an intermediate portion that connects a ratchet portion 4a on the front end side and a rear end portion 4c is a spring portion 4b that can expand and contract in the axial direction. The spring portion 4b is a resin spring that is integrally formed with the ratchet portion 4a and the rear end portion 4c, and has a substantially spiral shape.

A plurality of ratchet teeth 4x for ratchet engagement with the ratchet teeth 5x of the female screw member 5 are arranged along the circumferential direction on the distal end surface of the ratchet portion 4a. Further, on the outer peripheral surface of the ratchet portion 4a, a plurality (eight in this example) of ridges 4d extending in the axial direction are provided along the circumferential direction for engaging with the grooves 1c of the container body 1 in the rotational direction. They are arranged evenly. Also, on the outer peripheral surface of the rear end portion 4c, a plurality of (here, four) ridges 4e extending in the axial direction are provided along the circumferential direction for engaging with the grooves 1c of the container body 1 in the rotational direction. ) are arranged at equal intervals. The ridge 4e of the rear end portion 4c is arranged on an extension line of the ridge 4d of the ratchet portion 4a.

The tip tube 2 is formed in a tapered cylindrical shape, and has a collar part 2x in the middle in the axial direction with which the tip surface of the container body 1 abuts. A portion of the front tube 2 on the rear side of the flange portion 2x is used as an insertion portion that is inserted into the container body 1. As shown in FIG.

A cylindrical hole penetrating in the axial direction of the front tube 2 extends from the tip to a point past the flange 2x, and the cylindrical hole serves as an eyeliner hole 2a through which the eyeliner M and the piston 6 move forward. A rear end of the eyeliner hole 2a is connected to a large-diameter hole that opens rearward, and the female screw member 5 is accommodated in the large-diameter hole so as to be synchronously rotatable and axially immovable.

The female screw member 5 is configured in a substantially cylindrical shape, and has a female screw 5a along the inner peripheral surface of the distal end thereof, which is screwed into the male screw 3a formed on the outer peripheral surface of the front half of the moving body 3. . A plurality of ratchet teeth 5x that mesh with the ratchet teeth 4x of the ratchet spring member 4 are arranged along the circumferential direction on the rear end face of the female screw member 5 on the outer peripheral side.

The tip tube 2 is rotatable and axially immovable with respect to the container body 1 in a state in which the insertion portion thereof is inserted from the front side of the container body 1 and the collar portion 2x is abutted against the tip surface of the container body 1. is attached to the

The ratchet spring member 4 is sandwiched between the female screw member 5 of the front tube 2 and the stepped surface 1b of the ridge 1a of the container body 1. However, by engaging with the groove 1c of the container body 1 in the rotational direction, it is attached to the container body 1 so as to be synchronously rotatable, the spring portion 4b can be extended and contracted in the axial direction, and the ratchet portion 4a can be moved in the axial direction. be.

When the container body 1 and the tip tube 2 are relatively rotated in one direction, the male screw 3a of the moving body 3 rotating synchronously with the container body 1 and the ratchet spring member 4 and the female screw member rotating synchronously with the tip tube 2 are arranged. The moving body 3 and the piston 6 move forward due to the screwing action of the female screw 5a of 5. As shown in FIG. At this time, when the ratchet spring member 4 and the female thread member 5 are rotated relative to each other by the relative rotation of the container body 1 and the tip tube 2 in one direction, the spring portion 4b is contracted to release the engagement of the ratchet teeth 4x and 5x. Disengagement and return to engagement, in which the ratchet teeth 4x are advanced by the biasing force of the spring portion 4b and engage with the ratchet teeth 5x, are repeated, giving a click feeling to the user. By giving such a click feeling to the user, the user can gradually let out the eyeliner M by the rotating operation, so that the shape of the eyeliner M can be maintained. The ratchet mechanism consisting of the ratchet teeth 4x and 5x is configured such that when the container body 1 and the tip tube 2 are relatively rotated in the other direction, the ratchet teeth 4x and 5x are firmly engaged and the engagement is not released. Therefore, even if the container body 1 and the tip tube 2 are relatively rotated in the other direction, the screwing action by the male screw 3a and the female screw 5a does not work, and the moving body 3 does not retreat.

Next, the configuration of the opening 7 at the tip of the tip tube 2, which characterizes this embodiment, will be described.

FIG. 3 is a longitudinal sectional view showing the tip of the tip tube before filling the eyeliner, FIG. 4 is a side view showing the tip of the tip after filling the eyeliner, and FIG. 4 is a perspective view of 4 viewed obliquely from the front and above.

As shown in FIGS. 3 to 5, an opening edge 7x that forms (borders) the opening 7 at the tip of the front barrel 2 is located on the front side of the lower left side in FIG. An edge portion 7a, a right and upper rear edge portion 7c in FIG. 3, and an intermediate edge portion 7b connecting the rear end of the front edge portion 7a and the front end of the rear edge portion 7c so as to form a step. .

The front edge portion 7a includes a front end portion 7d (see FIG. 5) that bulges slightly forward in a rounded shape on the left side of the bottom in FIGS. In the view from the left side), it continues on both sides of the front end portion 7d, and has inclined surfaces 7e with an upward slope on both sides from the approximate center of the bottom like a bamboo shoot cut obliquely in a side view. That is, it has an inclined surface 7e extending rearward from the front end portion 7d while being inclined at a substantially constant angle.

The intermediate edge portion 7b has a horizontal surface 7f that extends horizontally rearward following the rear end of the front edge portion 7a.

The rear edge portion 7c continues to the rear end of the horizontal surface 7f and has an inclined surface 7g (substantially parallel to the inclined surface 7e) with the same upward slope as the inclined surface 7e, as if a bamboo shoot is cut obliquely in a side view. That is, it has an inclined surface 7g extending upward and rearward from the rear end of the horizontal surface 7f while being inclined at a substantially constant angle, and the rear end portion 7h (see FIG. 5) at the upper approximately center of FIG. 3 where the inclined surfaces 7g meet. It has a configuration including Therefore, the front side edge portion 7a and the rear side edge portion 7c are connected via the intermediate edge portion 7b forming a step.

Here, the eyeliner M filled in the eyeliner hole 2a of the front barrel 2 is poured into the eyeliner hole 2a through the opening 7 of the front barrel 2 while the stick-shaped cosmetic dispensing container 100 is assembled. It can be obtained by solidifying.

In the shipping state (initial state) of the stick-shaped cosmetic dispensing container 100, as shown in FIGS. It has a tip shape that follows the opening edge 7x. That is, in a side view, the upper part of the tip of the eyeliner M is exposed upward from the opening 7 of the tip tube 2, and the lower part of the tip is covered by the tip tube 2 from below and is guarded. state.

Next, an example of how to use the stick-shaped cosmetic dispensing container 100 will be described.

FIG. 6 is a side view of the front tube with the eyeliner drawn out, and FIG. 7 is a perspective view of FIG. 6 viewed obliquely from the front and above.

The user first rotates the container body 1 and the tip tube 2 relative to each other in the delivery direction (one direction), moves the moving body 3 forward, and pushes out the eyeliner M with the piston 6 . At this time, the ratchet mechanism consisting of the ratchet teeth 4x and 5x prevents the eyeliner M from protruding too much while giving a click feeling, and the eyeliner M protrudes moderately as shown in FIGS.

The eyeliner M protruding axially forward from the tip of the front tube 2 has a first application surface M1 along the front edge 7a inside the front edge 7a including the front end 7d. A second application surface M2 is formed along the rear edge 7c inside the rear edge 7c including the portion 7h, and a first application surface M1 and a second application surface M1 are formed inside the intermediate edge 7b. It protrudes forward in a state where a surface M3 connecting with M2 is formed. That is, from the front end portion of the front tube 2, the first application portion T1 is located on the lower side in a side view having the first application surface M1 on the front end surface, and the upper side in the side view having the second application surface M2 on the front end surface. , the second coating portion T2 on the rear side of the first coating portion T1 protrudes.

Here, for example, when drawing a thin raised line at the outer corner of the eye, it is preferable to use the first application portion T1 having the first application surface M1.

8 is a side view showing a state in which the first eyeliner applicator is used and the second applicator is used to some extent from the state of FIG. 6, and FIG. 9 is a perspective view of FIG. 8 viewed obliquely from above. It is a diagram.

Here, for example, after drawing a thin upward line of the outer corner of the eye and using up the first application part T1 shown in FIGS. 6 and 7, the second application part T2 having the second application surface M2 is used. , shows an example in which the second application part T2 is somewhat consumed by drawing an eyeline from the inner corner to the outer corner of the eye. The second application part T2 is suitable for drawing an eyeline extending from the inner corner of the eye to the outer corner of the eye.

Then, as it is, the second application part T2 is used up, the shape of the eyeliner M in the initial state shown in FIGS. 4 and 5 is restored, and the eyeliner M is drawn out again as shown in FIGS. It is also possible to repeat this series of operations. After the first coating portion T1 has been used up and the second coating portion T2 has been mostly used, the remaining second coating portion T2 is cut using a knife or the like to return to the state shown in FIGS. Again, as shown in FIGS. 6 and 7, the eyeliner M may be extended and used, and these series of operations may be repeated. Also, after the first application part T1 shown in FIGS. 6 and 7 has been used up, the eyeliner M is cut using a knife or the like without using the second application part T2, and the eyeliner M is cut as shown in FIGS. , the eyeliner M may be drawn out and used again as shown in FIGS. 6 and 7, and these series of operations may be repeated. In other words, the stick-shaped cosmetic delivery container 100 may be configured such that only the first application portion T1 of the eyeliner M is exclusively used and a splash line for the outer corner of the eye is exclusively drawn.

As described above, according to the present embodiment, the tip of the eyeliner M has a tip shape along the opening edge 7x at the tip of the tip tube 2, which is the tip of the container, and thus includes the front end 7d. A first application surface M1 along the front edge 7a is formed inside the front edge 7a, and a second coating surface M1 along the rear edge 7c is formed inside the rear edge 7c including the rear edge 7h. A surface that connects the first coating surface M1 and the second coating surface M2 on the inner side of the intermediate edge portion 7b that forms a step between the front edge portion 7a and the rear edge portion 7c. M3 is formed. Then, the eyeliner M having these surfaces M1, M2, and M3 is drawn out and protruded from the opening 7 at the tip of the front tube 2 to form a first application portion T1 having a first application surface M1 on the tip surface, and a first application portion T1. A second application portion T2 having two application surfaces M2 on the tip surface is brought into contact with each of the portions to be applied for application. Therefore, the sizes of the first and second application parts T1 and T2 are naturally smaller than the original size of the eyeliner M housed in the front barrel 2. As shown in FIG. Therefore, it is possible to easily draw a line thinner than the original line drawn by the eyeliner M in the tip tube 2. - 特許庁

The front edge portion 7a extends rearward from the front edge portion 7d while being inclined at a substantially constant angle with respect to the axial direction, and the rear edge portion 7c extends rearward from the rear edge portion 7h so as to be substantially parallel to the front edge portion 7a. , and the intermediate edge portion 7b extends from the rear end of the front side edge portion 7a and connects to the front end of the rear side edge portion 7c. It becomes a flat application surface inclined at the same angle. Therefore, if each application surface M1, M2 is applied to the corresponding application area in sequence, the eyeliner M inside the tip tube 2 can be drawn from the original drawn line without changing the angle of the stick-shaped cosmetic delivery container 100. You can draw fine lines easily.

Here, the intermediate edge portion 7b as a whole extends along the axial direction. are R-shaped, and extend along the axial direction between connecting portions of the intermediate edge portion 7b.

As described above, the present invention has been specifically described based on the embodiments, but the present invention is not limited to the above embodiments. However, it can also be applied to an eyeliner having a drop-shaped cross section or an elliptical eyeliner.

Further, in the above embodiment, a ratchet mechanism is employed to allow only the advance of the eyeliner M, but the ratchet mechanism may be omitted.

In the above-described embodiment, since the eyeliner M has a particularly small diameter, it is a stick-shaped cosmetic dispensing container of a piston pushing type. You may apply it with respect to a container.

In the above-described embodiment, the front edge portion 7a and the rear edge portion 7c are inclined edges, but the front edge portion 7a includes the front end portion 7d on the lower side in side view and is perpendicular to the axial direction. The rear edge portion 7c is a vertical rear edge portion that includes the rear end portion 7h on the upper side in the side view and is perpendicular to the axial direction, and the vertical front edge portion and the rear edge portion form a step. A configuration in which they are connected at the intermediate edge portion 7b may also be used. Moreover, although it is particularly preferable that the intermediate edge portion 7b is a horizontal surface, it may be, for example, an inclined surface instead of the horizontal surface.

In the above-described embodiment, the stick-shaped cosmetic is used as an eyeliner because it is particularly suitable for drawing thin lines. It can also be applied to draw a thin line at the corners of the mouth using the stick-shaped cosmetic as a lipstick.

Furthermore, it is not limited to the delivery of the stick-shaped cosmetic by relative rotation, and can be applied to a type in which the stick-shaped cosmetic is delivered by knocking a knock operation part, such as a known pencil-type knock type. In short, it can be applied to all types in which a stick-shaped cosmetic material is fed out by operating the operating portion.
