DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic container for accommodating a stick-shaped cosmetic material so as to be able to be fed out, and an improvement of a cartridge for the cosmetic material container.

[0002]

2. Description of the Related Art As a cosmetic material container for feeding a rod-shaped cosmetic material such as an eyeliner, an eyebrow, an eye shadow, a lipstick, and the like housed in a cartridge from an opening at an upper end of the cartridge by rotating the cartridge and the container body, for example, Japanese Unexamined Patent Publication No. 60-48706, 4-309
A proposal has been made in, for example, Japanese Patent Publication No. 61-61 and the like.

Further, in such a cosmetic material container,
When the cartridge is removed from the container body, the rod-shaped decorative material that has been drawn out of the cartridge is automatically accommodated in the cartridge. For example, Japanese Patent Publication No. 3-50814 and Japanese Utility Model Publication No. 6-21390 by the present applicant. Has been proposed.

[0004] Of these, in the cosmetic container disclosed in Japanese Utility Model Publication No. 3-50814, a feeding mechanism is provided in the container body. The dispensing mechanism operates in accordance with the rotation of the cartridge mounted on the container body, and dispenses a push rod provided on the container body so as to be slidable in the axial direction. The extruded rod pushes out the stick-shaped decorative material in the cartridge. Each of the push rod and the support member for the stick-shaped decorative material is provided with a return spring, and when the cartridge is removed from the container body, the return is performed automatically.

[0005] In the cosmetic material container disclosed in Japanese Utility Model Publication No. 6-21390, the feeding mechanism is provided on the cartridge side.
A shaft is erected on the container body. The shaft bar is a guide shaft for a push bar that is fed by the feed mechanism, and engages with the push bar so as to be non-rotatable and slidable in the axial direction. Thus, when the container body and the cartridge rotate, the push rod rotates with respect to the cartridge, the push rod is fed out by the feeding mechanism, and the stick-shaped cosmetic material held at the upper end of the push rod is fed out. Further, a return spring that pushes the push rod back to the initial position is provided on the cartridge side, and when the cartridge is removed from the container body, the stick-shaped cosmetic material is pulled back to the initial position.

[0006]

However, in the cosmetic container disclosed in Japanese Utility Model Publication No. 3-50814, when the cartridge is removed from the container body, the push rod on the container body and the rod-shaped decorative material on the cartridge side are supported. To return each of the members, a separate return spring is required, which increases the cost of the entire cosmetic material container. Further, the cosmetic material container requires a total length obtained by adding a length corresponding to the cartridge to a length corresponding to the cartridge, and the length of the decorative material container is increased.

On the other hand, the cosmetic material container disclosed in Japanese Utility Model Publication No. 6-21390 has the advantage that only one return spring is required and the overall length of the cosmetic material container can be relatively shortened. Since a shaft having a length corresponding to the stroke needs to be erected on the container main body, the configuration of the container main body becomes complicated. In addition, it is necessary to form a hole in which the shaft rod engages with the push rod, and a certain thickness is required.Therefore, the cosmetic material container has to be thicker by the thickness of the push rod, and has a small diameter. It is difficult to make it applicable to cosmetic materials. Further, since the push rod rotates synchronously with the container body when the feeding mechanism is operated, in order to prevent the fed rod-shaped cosmetic material from rotating with respect to the cartridge, the supporting member of the rod-shaped decorative material is separated from the push rod. Must be
The configuration of the cartridge becomes complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and simplifies the structure of the container body in a cosmetic container cartridge or a cosmetic container in which a stick-shaped cosmetic material is automatically returned by removing the cartridge. As well as adaptable to various kinds of stick-shaped cosmetic materials,
It is another object of the present invention to provide an automatic return device having a stable operation.

[0009]

According to a first aspect of the present invention, a stick-shaped decorative material is removably mounted on a container body to house and hold therein a rod-shaped decorative material, and the rod-shaped decorative material is advanced and retracted from an upper end opening by rotation with the container main body. In the cosmetic material container cartridge to be
A front cylinder having the upper end opening, and a cylinder housed rotatably and non-slidably in the front cylinder, wherein a cartridge body is constituted by the front cylinder and the cylinder, and the cartridge body is provided inside the cartridge body. A sliding mechanism that accommodates the rod body, forms a cosmetic material holding portion that holds the rod-shaped cosmetic material on the upper end side of the rod body, and holds the rod body in the front cylinder in a non-rotatable and slidable manner; ,
A feeding mechanism for feeding the rod body in the axial direction by rotation of the rod body and the cylindrical body; and a spring for constantly urging the rod body rearward. Synchronous engagement portions are provided.

In a second aspect of the present invention, a lower end of the cylindrical body and a lower end of the front cylinder have substantially the same height, and the synchronous engaging portion is formed on an inner peripheral surface on a lower end side of the cylindrical body. By spline-engaging a synchronous engagement shaft provided on the bottom of the container body with this spline groove,
The cylinder and the container body are synchronously engaged.

[0011] In the third aspect, the feeding mechanism includes a spiral portion formed on an outer periphery of the rod body and a spiral groove formed on a peripheral surface of the cylindrical body and a part of the spiral portion is screwed.

In the fourth aspect of the present invention, a non-projection portion having no spiral portion is formed on the base end side of the rod body, and the rod body has been stroked to a position where the non-projection portion is opposed to the spiral groove. However, the upper limit of the stroke of the rod was set.

In the fifth invention, the sliding mechanism includes an engaging portion formed on the outer periphery of the rod body and a sliding portion formed on the inner periphery of the front cylinder and engaging with the engaging portion. Equipped.

In a sixth aspect of the present invention, the engaging portion of the sliding mechanism is a plurality of claw pieces which are held so as to surround the rod-shaped decorative material, and the rod-shaped decorative material is provided between the claw pieces by the tip. It is supported from the side by the inner peripheral surface of the cylinder.

In the seventh invention, a small diameter portion is formed in the front cylinder so as to be located immediately above the cylinder, and the sliding portion is formed on the inner peripheral surface of the small diameter portion.

In the eighth invention, the plurality of spiral portions are a plurality of engagement protrusions disposed on a straight line extending in the axial direction below the engagement portion, and are extended to the upper portion of the front cylinder. When this occurs, it becomes an engaging portion that engages with a sliding portion formed on the upper side of the front cylinder.

According to a ninth aspect, the spring is a coil spring wound around the outer periphery of the rod body, and an upper end of the coil spring abuts on a downward step formed on the cylindrical body. The lower end is in contact with an upwardly directed step provided on the rod body.

In a tenth aspect, an O-ring is provided between the outer periphery of the front cylinder and the inner periphery of the container body, and a frictional force generated by the O-ring reverses the front cylinder of the spring and the container body. It was made to be larger than the repulsive force to rotate.

According to an eleventh aspect of the present invention, there is provided the cartridge according to any one of the first to tenth aspects, and a container main body in which the cartridge is detachably accommodated, wherein the cartridge is accommodated in the container main body. The tip cylinder is rotatable with respect to the container main body, while the feeding member is non-rotatably connected to the container main body via the synchronous engagement portion.

[0020]

In the present invention, when the stick-shaped decorative material is fed from the decorative material container, the front cylinder of the cartridge is rotated in a predetermined forward direction with respect to the container main body while the cartridge is housed in the container main body. . In this case, since the rod and the tip cylinder are prohibited from rotating by the sliding mechanism, and the cylinder and the container body are prohibited from rotating by the synchronous engagement means, respectively.
The rod and the cylinder rotate. As a result, the feeding mechanism causes the rod to stroke, and the stick-shaped decorative material is fed from the front end opening of the front cylinder.

On the other hand, when the stick-shaped decorative material is pulled back to the decorative material container, the front cylinder and the container body are rotated in the reverse direction to the time of feeding, and the rod is moved in the stroke lower limit direction.

Alternatively, by removing the cartridge from the cosmetic material container with the rod-shaped cosmetic material being unwound, the rod body is pulled back to the lower stroke limit by the urging force of the urging means, and the rod-shaped cosmetic material is automatically moved forward. Pull it into the cylinder (auto return). In this way, the user of the cosmetic material container can retreat the rod-shaped cosmetic material only by pulling out the cartridge in a state where the rod-shaped cosmetic material is protruding, and the operation of lowering the cosmetic material container can be simplified, and the rod-shaped cosmetic material can be broken. Can also be prevented.

In such a feeding and retracting operation, the stick-shaped decorative material does not rotate with respect to the front cylinder. Therefore, since the stick-shaped decorative material makes a stroke in a smooth and stable operation, even when the stick-shaped decorative material automatically returns, for example, the stick-shaped decorative material is unlikely to be broken.

Further, since the container body is connected to the cylinder via the synchronous engagement means, the container is automatically returned when the cartridge is pulled out from the container body, even though the rod-shaped cosmetic material is automatically returned. The configuration of the main body can be simplified.

In particular, if the synchronous engaging means and the synchronous engaging shaft are spline-engaged as in the second aspect of the invention, the container body need only be provided with a small synchronous engaging shaft. Therefore, the configuration of the container body can be extremely simplified, and can be easily manufactured as a single member by, for example, molding, so that the manufacturing cost can be significantly reduced. Further, since the length of the container body can be easily set, it is easy to construct a cosmetic material container having a length that is easy to use.

Further, since it is not necessary to provide a hole for coupling with the container body, the rod body can be made to have a small diameter, and accordingly, the diameter of the cartridge body can be made sufficiently small. Therefore, a cosmetic material container suitable for a small-diameter rod-shaped decorative material can be easily configured.

Since the cylindrical body is accommodated in the front cylinder, the outer frame of the cartridge is constituted by the front cylinder which is a member. Therefore, when the cartridge is removed from the container body,
With the cartridge alone, the user cannot hold the front cylinder and the cylinder and rotate them. That is, unless the cartridge is mounted on the container body, the operation of feeding the stick-shaped decorative material from the cartridge is not performed. Therefore, when the cartridge is removed from the container body and handled, the stick-shaped cosmetic material is unwound by mistake, and
It is possible to prevent the stick-shaped decorative material from being damaged or broken.

In the fourth aspect of the present invention, the rod body stroke reaches the upper limit in which the rod-shaped decorative material cannot be extended because the guide projection comes out of the spiral groove. In addition, since the rod body is urged downward by the spring, when the cartridge and the container body that have reached the ascending limit are idled, there is a contact sound between the spiral groove end of the rod body and the guide projection of the guide rod, The user is notified that the stroke has reached the upper limit. Therefore, the cosmetic material container is not subjected to an operation (for example, an operation of compressing the spring beyond the compression limit) that makes the mechanism in the cartridge unreasonable, so that the mechanism in the cartridge can be prevented from being damaged.

In the sixth aspect of the present invention, the decorative material holding portion is constituted by nail pieces, and the rod-shaped decorative material is supported between the nail pieces from the side by the inner peripheral surface of the front cylinder. Thus, the stick-shaped decorative material can be securely held, and even if the stick-shaped decorative material has a small diameter, it can be prevented from being broken during a stroke.

In the seventh aspect, if the sliding portion is formed on the inner peripheral surface of the small diameter portion, it is not necessary to form the sliding portion on the inner peripheral surface on the upper side of the front cylinder. Therefore, as the stick-shaped decorative material, a type formed by filling a liquid cosmetic material raw material from the upper end opening of the front cylinder can be adopted. Further, in this case, since the small diameter portion is provided above the cylindrical body, the cosmetic material material does not easily flow to the cylindrical body side, and the production efficiency of the decorative material container can be increased. Furthermore, unlike the case where the upper inner peripheral surface of the front cylinder and the decorative material holding portion are fitted with different diameters to constitute a sliding mechanism, the upper inner peripheral cross section of the front cylinder can be made a perfect circle.

In the eighth aspect, when the rod body makes a stroke, the helical portion sequentially engages with the sliding portion of the sliding mechanism. Therefore, the helical portion is a component of the feeding mechanism that is screwed into the helical groove. In addition to acting, it also acts as an engaging portion of the sliding mechanism. Therefore, the stroke of the rod body can be further stabilized, and the cartridge can be made resistant to a load in the torsion direction. Further, the diameter of the cartridge can be extremely small.

In the ninth invention, the coil spring is wound around the outer periphery of the rod body, and the coil spring is interposed between the downwardly stepped portion of the cylindrical body and the engaging portion of the rod body. The mounting structure can have a simple configuration, and the operation of mounting the spring can be easily performed, and the manufacturing cost of the cosmetic material container can be reduced.

In the tenth aspect, the frictional force generated by the O-ring is set to be larger than the repulsive force of the spring (the torque given by the frictional force is set to be larger than the torque given by the repulsive force of the spring). Therefore, a mechanism for holding the rotational position of the cartridge against the spring force can be configured with a simple configuration at a low cost. Further, the frictional force of the O-ring gives an appropriate weight (resistance) to the rotation operation of the cartridge, and gives a heavy operation feeling to the rotation operation. Further, wobbling of the cartridge can be suppressed by the O-ring.

[0034]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a cosmetic container cartridge 1 according to a first embodiment of the present invention. FIG. 2 shows FIG.
FIG. 3 shows a container body 2 to which the cartridge 1 of FIG. 1 is detachably mounted. The cosmetic material container includes the cartridge 1 shown in FIG. 1 and the container body 2 shown in FIG.

The cartridge 1 accommodates the rod-shaped decorative material 4 so as to be able to be fed out, and includes a front cylinder 10, a cylindrical body 20, a rod body (push rod) 30, and a return spring 6.

The front cylinder 10 is a cylindrical member constituting the outer frame of the cartridge 1, and comprises an exposed portion 10A on the upper end side with respect to the step portion 10C and a housing portion 10B on the lower end side. When the cartridge 1 is mounted on the container body 2, the exposed portion 10
A is exposed to the outside of the container body 2, and the housing portion 10 </ b> B is housed inside the container body 2.

The inside of the front cylinder 10 on the side of the exposed portion 10A is:
It is a cosmetic material accommodation hole 11 in which the rod-shaped cosmetic material 4 is accommodated. This cosmetic material accommodation hole 11 is configured to have an elliptical cross section,
As will be described later, the decorative material holding portion 31 of the rod body 30 is fitted in a non-rotatable manner with a different diameter. Further, the rod-shaped decorative material 4 held by the decorative material holding portion 31 and accommodated in the interior of the cosmetic material accommodating hole 11 is provided.
Is fed out of the opening 12 at the upper end of the front cylinder 10 so as to be freely retractable.

The receiving portion 10 B of the front cylinder 10 has an outer diameter substantially equal to the inner diameter of the container body 2. In addition, an annular fitting projection 14 is formed on the outer periphery of the housing portion 10B. When the housing portion 10 </ b> B is housed in the container body 2, the fitting protrusion 14 is fitted with an annular fitting recess 41 formed on the inner peripheral surface of the container body 2. Thereby, the front cylinder 10 and the container main body 2 are positioned so as not to be movable in the axial direction (impossible to come out), and are rotatable in the rotation direction.

The inside of the front cylinder 10 on the side of the housing portion 10B has a circular cross section, and has a cylindrical body 20 having an outer diameter substantially equal to this inner diameter.
Is accommodated. The front cylinder 10 and the cylinder 20 constitute a cartridge body.

In this case, the fitting convex portion 21 formed on the outer peripheral surface of the cylindrical body 20 is fitted to the fitting concave portion 1 formed on the inner peripheral surface of the front cylinder 10.
5 is fitted. As a result, the cylindrical body 20 is positioned so as to be unable to move (can not come out) in the axial direction with respect to the front cylinder 10, while being rotatable in the rotational direction.

The lower end of the front cylinder 10 and the lower end of the cylinder 20 are aligned at substantially the same height, and the cylinder 20 is completely housed inside the front cylinder 10.

On the inner peripheral surface of the lower end of the cylindrical body 20, there is formed a synchronous engaging portion 26 comprising a plurality of longitudinal grooves (spline grooves) extending in the axial direction. On the other hand, the bottom 4 of the container body 2
2, a synchronous engagement shaft 43 is fixedly mounted.
A plurality of ridges (spline projections) extending in the axial direction are formed on the outer periphery of 3. Thereby, when the cartridge 1 is housed in the container main body 2, the synchronous engaging portion 26 non-rotatably engages with the synchronous engaging shaft 43 (spline coupling),
The cylindrical body 20 and the container body 2 are non-rotatably connected. Therefore, when the cartridge 1 is mounted on the container body 2,
When the front cylinder 10 is rotated with respect to the container body 2, the front cylinder 10 is rotated.
Then, the cylindrical body 20 rotates.

A predetermined length on the upper end side of the cylindrical body 20 is a spiral cylindrical portion 22 having a small inner diameter. This spiral cylinder 22
Is formed with a spiral groove 23 on the inner peripheral surface thereof. This spiral groove 2
A plurality of engagement protrusions 35 as helical portions on the outer periphery of a rod body 30 to be described later are screwed into 3.

The cartridge body (the front cylinder 10 and the cylinder 2
The rod 30 is coaxially accommodated in the inside of 0). At the upper end side (opening 12 side) of the rod body 30, a cosmetic material holding portion 31 is provided.
Is provided. The cosmetic material holding portion 31 is a cup having an elliptical cross section so as to fit into the cosmetic material housing hole 11 with a different diameter, and holds the lower end of the rod-shaped decorative material 4 in the cup.

It should be noted that the sliding mechanism is not limited to the fitting of the cosmetic material holding portion 31 and the cosmetic material receiving hole 11 of different diameters by ellipse, but may be of a polygonal shape with different diameters. In addition, the sliding mechanism includes a sliding protrusion (engaging portion) formed on the rod body 30 (for example, an outer peripheral surface of the cosmetic material holding portion 31), and an inner peripheral surface of the front cylinder 10 (for example, an inner peripheral surface of the cosmetic material receiving hole 11). ) May be constituted by a mechanism that engages with a sliding groove (sliding portion) formed in (1), and may take various forms (for example, see a second embodiment described later).

The rod 30 can be stroked in the axial direction in the cartridge body. Thereby, the stick-shaped decorative material 4 held coaxially by the decorative material holding portion 31 is
The rod advances and retreats from the front cylinder opening 12 with the stroke of the rod body 30.

On the outer periphery of the rod 30, from just below the cosmetic material holding portion 31 to the length of the stroke of the rod 30,
The plurality of engaging projections 35 are formed on a straight line extending in the axial direction. The group of the engagement protrusions 35 is arranged so as to conform to the spiral groove 23 of the spiral cylinder portion 22 (arrangement along the spiral track). A part is screwed with the spiral groove 23.

The spiral groove 23 and the plurality of engaging projections 35 constitute a mechanism for feeding the cosmetic material container. That is, when the front cylinder 10 (the rod body 30) and the container body 2 (the cylinder body 20) are rotated, the plurality of engagement projections 35 are sequentially screwed into the spiral grooves 23, and the rod body 30 is To be paid out.

The lower limit of the stroke of the rod 30 is the stroke position at which the decorative material holding portion base 32 contacts the upper end 20A of the cylindrical body.

In the present embodiment, the plurality of engaging projections 35 are spirally arranged on the rod body 30 and are sequentially screwed into the spiral groove 23 for feeding. However, the shape to be screwed into the spiral groove 23 is as follows. It is needless to say that the thread is not limited to the engagement projection 35 but may be a normal male screw-shaped spiral portion screwed into the spiral groove 23, for example.

Below the row of the engagement projections 35 of the rod body 30, there is provided a non-projection portion 36 on which the engagement projections 35 are not formed. Then, as shown in FIG. 4, when the rod body 30 is stroked and the non-projecting portion 36 rises to a position facing the spiral cylinder 22, all the engaging projections 35 escape from the spiral groove 23. As a result, even if the front tube 10 is rotated, the feeding mechanism does not function, and the rod 30 does not further stroke. That is, this stroke position becomes the upper limit of the stroke of the rod 30. The upper limit of this stroke is set so that a return spring 6 described later does not contract beyond the contraction limit.

A return spring 6, which is a coil-shaped push spring, is provided on the outer periphery of the rod body 30. The upper end of the return spring 6 abuts on the lower end surface 22A (downward step) of the helical tubular portion 22, and the lower end abuts on the upper surface 34A (upward step) of the locking member 34 of the rod 30. As a result, the rod body 30 is constantly urged axially downward by the return spring 6. The locking member 34
Is a spring seat member mounted on the outer periphery near the lower end of the rod 30 (below the non-projecting portion 36).

A ring groove 18 is formed at a predetermined position on the outer peripheral surface of the housing portion 10B of the front cylinder 10. This ring groove 1
The O-ring 5 is fitted into 8 as resistance applying means.

The frictional force (torque generated by the frictional force) generated between the O-ring 5 and the container body 2 is a repulsive force for the return spring 6 to reversely rotate the front cylinder 10 and the cylindrical body 20 (this repulsion). (Reverse torque due to force). This allows
When the cartridge 1 and the container body 2 are rotated, the cartridge 1 and the container body 2 are not rotated in reverse by the return spring 6 that pushes the rod 30 down, and the rotational position is maintained. Is done.

On the other hand, if the cartridge 1 is removed from the container main body 2 while the cartridge 1 is rotated (the rod-shaped decorative material 4 is unwound), the frictional resistance of the O-ring 5 is lost. The rod-shaped decorative material 4 is automatically retracted into the cartridge by being pulled back to the stroke lower limit by the spring force.

The frictional resistance of the O-ring 5 gives an appropriate weight (resistance) to the rotation of the cartridge 2, so that the user of the cosmetic material container is given a heavy operation feeling. The O-ring 5 can also prevent the cartridge 1 from wobbling in the container body 2.

Next, the procedure for assembling the cosmetic material container 1 will be described.

In assembling, first, the rod body 30 is inserted into the opening on the upper end side of the cylindrical body 20 from the lower end side without the locking member 34 attached. Then, by engaging the engagement protrusion 35 with the spiral groove 23, the cylindrical body 2 is formed.
The rod body 30 is incorporated in 0. Subsequently, the return spring 6 is inserted from the lower end side of the cylindrical body 20 and wound around the rod body 30. Further, the locking member 34 is attached to the rod body 30, and the return spring 6 is sandwiched between the lower end surface 22A of the spiral cylinder and the upper surface 34A of the locking member.

The cylindrical body 2 in which the rod 30 is incorporated as described above.
0 is positioned so that the cosmetic material holding portion 31 on the upper part of the rod 30 is accommodated in the cosmetic material accommodation hole 11,
Insert from the lower end opening of. Then, by pushing the fitting protrusion 21 on the outer periphery of the cylinder 20 into the fitting recess 15 on the inner periphery of the front cylinder 10, the cylinder 20 is assembled so as to be entirely housed inside the front cylinder 10. Further, the O-ring 5 is fitted into the ring groove 18 on the outer periphery of the front cylinder 10 to
Is completed.

The cartridge 1 is inserted into the container body 2
By attaching to the container, a cosmetic material container is completed. Specifically, the cartridge 1 is accommodated in the upper opening of the container main body 2 from the lower end side, the synchronous engagement shaft 43 of the container main body 2 is fitted to the synchronous engagement portion 26 of the cylindrical body 20, and the outer peripheral surface of the front cylinder 10 is The fitting protrusion 14 is fitted into the fitting recess 41 on the inner peripheral surface of the container body 2. Thereby, the front cylinder 10 is mounted so as to be rotatable with respect to the container main body 2, and the cylindrical body 20 is mounted so as not to be rotatable with respect to the container main body 2. In this case, since the synchronous engaging portion 26 and the synchronous engaging shaft 43 do not have an assembly directionality, the cartridge 1
The mounting of the container body 2 can be easily performed.

Next, a method of using the cosmetic material container of the present embodiment will be described.

When the stick-shaped decorative material 4 is paid out from the cartridge 1, first, the cartridge 1 is mounted in the container body 2. The user holds the container body 2 and the exposed portion 10A of the cartridge 1 exposed from the container body 2, and rotates the cartridge 1 and the container body 2 in a predetermined normal rotation direction. In this case, since the rod body 30 rotates synchronously with the front cylinder 10 by engagement with the front cylinder 10 via the sliding mechanism (the fitting of the cosmetic material holding portion 31 and the cosmetic material accommodation hole 11 with different diameters), It rotates with respect to the cylinder 20 synchronously engaged with the container body 2. As a result, the plurality of engagement projections 35 on the outer periphery of the rod body 30 are sequentially screwed into the spiral grooves 23 on the inner periphery of the spiral cylinder 22, and the feeding mechanism functions. As a result, the rod 30 is extended from the upper end side of the cylindrical body 20, and the decorative material holding portion 31 at the upper end of the rod 30 is provided.
The rod-shaped decorative material 4 held in the
It is paid out from.

When the stick-shaped decorative material 4 is pulled into the cartridge 1, if the cartridge 1 and the container main body 2 are rotated in the reverse direction, each component of the decorative material container operates in the opposite direction to that described above. Moves back into the cartridge 1.

Alternatively, the cartridge 1 is removed from the container body 2 while the stick-shaped decorative material 4 is being fed out. As a result, the spring force of the spring 6, which constantly urges the rod body 20 downward, is pulled back downward while rotating the rod body 30, and the rod-shaped decorative material 4 is automatically retracted into the cartridge 2 (auto return). Do). As described above, the user of the cosmetic material container 1 can retreat the rod-shaped cosmetic material 4 only by pulling out the cartridge 2 in a state where the stick-shaped cosmetic material 4 is protruding, and the operation of moving down the cosmetic material container 1 is simplified, and When the cartridge 1 is used alone, the stick-shaped decorative material 4 can be prevented from breaking.

In using such a cosmetic material container 1,
Each configuration of the present embodiment operates as follows.

Since the rod body 30 and the front cylinder 10 are engaged via a sliding mechanism (the fitting of the cosmetic material holding portion 31 and the cosmetic material receiving hole 11 having different diameters), the rod body 30 is It does not rotate with respect to the cylinder 10. Therefore, the stick-shaped decorative material 4 held by the decorative material holding portion 31 at the tip of the rod 30 is fed out from the opening 12 at the tip of the front cylinder 10 without rotating with respect to the front cylinder 10. Therefore, the stick-shaped decorative material 4 does not have to worry about being damaged or broken when moving forward and backward.

The O-ring 5 wound around the front cylinder accommodating portion 10B
Gives frictional resistance to the container body 2, and the action of the return spring 6 is controlled by this frictional resistance. That is, the frictional force generated between the O-ring 5 and the container body 2 is larger than the torque of the return spring 6 for rotating the front cylinder 10 and the cylinder body 20 in the reverse direction. Holds the rotation position of
The cartridge 1 is held in its rotational position. Further, the frictional resistance of the O-ring 5 gives an appropriate weight to the rotation of the cartridge 2, and gives the user of the cosmetic material container a heavy operation feeling. Also, with this O-ring 5,
The wobble of the cartridge 1 can also be suppressed.

The extension stroke of the rod 30 is, as shown in FIG. 4, completed by the completion of the screw engagement between the engagement projection 35 of the rod 30 and the spiral groove 23 of the spiral cylinder 22 (all the strokes). As a result, the engagement protrusion 35 comes out of the spiral groove 23), and the upper limit is reached. Further, if the rotation operation of the cartridge 1 and the container body 2 is continued after reaching the extension limit, the cylindrical body 20 and the rod body 30 rotate idly, but even in this case, the rod body 30 is lowered by the return spring 6. The lowermost row of the engagement projections 35a is
A contact sound (clicking sound) that touches the upper end of the is generated, and the user who hears this sound can recognize that the advance has reached the limit. Accordingly, the cosmetic material container is not subjected to an operation that would force the mechanism in the cartridge, and the mechanism in the cartridge is damaged (for example, the return spring 6 is compressed beyond the compression limit and is damaged. ) Can be prevented beforehand.

3 functions as a component of the feeding mechanism by screwing, and also functions as an engagement portion of the sliding mechanism by engaging with the sliding groove 112. Therefore, the stroke of the rod 130 can be further stabilized. In addition, even when a load in the torsional direction is applied to the cartridge 101, the load on the claw 132 can be reduced by the amount supported by the engagement protrusion 135, and the cartridge 101 can withstand a load in the torsional direction.

As described above, the cosmetic material container of this embodiment is
Since the stick-shaped decorative material 104 is supported from the side by the sliding surface 113 and the claw 132 is not overloaded, it can be stably fed with little wobble. For example, a delicate thin line is required. Done,
It is suitable for a soft bar-shaped decorative material 104 having a small diameter, such as an eyeliner, an eyebrow, and a lip liner.

FIG. 7 shows a cartridge 201 according to the third embodiment of the present invention.

The present embodiment differs from the first embodiment in that an inner diameter substantially equal to the outer diameter of the rod 230 is provided between the cosmetic material receiving hole 211 of the front cylinder 210 and the spiral cylinder 222. In that a small-diameter portion 250 having the following shape is formed.

With this configuration, at the lower limit of the stroke of the rod 230, the lower end of the decorative material holding portion 231 is
50 contacts the upper end surface 250A. In addition, the small diameter portion 250
Are formed on the inner peripheral surface of the rod body 230 at positions corresponding to the four straight lines on which the engagement protrusions 235 are formed, and these sliding grooves 251 have spirals. Part of the plurality of engagement protrusions 235 that have come out of the groove 223 is engaged. Thus, the sliding groove 251 and the engaging projection 235 engaged with the sliding groove 251 act as a sliding mechanism, so that the rod body 230 cannot rotate with respect to the front cylinder 210 and can slide in the axial direction.

As described above, the cartridge 2 of the present embodiment
According to No. 01, the sliding groove 251 is formed on the inner peripheral surface of the small-diameter portion 250, and it is not necessary to form a sliding portion in the cosmetic material accommodating hole 211. A type formed by filling from the upper end opening 212 of the cylinder 210 can be adopted. In this case, the small diameter portion 250
Since is provided above the cylindrical body 220, the cosmetic material raw material does not easily flow out to the cylindrical body 220 side, and the production efficiency of the cosmetic material container can be increased. Further, unlike the first embodiment, there is no need to form the sliding mechanism by fitting the cosmetic material holding holes and the cosmetic material holding portions with different diameters, so that the cross section of the cosmetic material housing hole 211 is a perfect circle. It can be.
