Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a cartridge-type cosmetic material container for accommodating a stick-shaped cosmetic material so that it can be unwound, when the cartridge is removed from the cosmetic material container body, the stick-shaped cosmetic material that has been unwound from the cartridge is automatically stored in the cartridge. The structure is, for example, the applicant's Japanese Utility Model Application No. 63-
No. 78346, for example.

FIG. 7 shows a cosmetic container (lipstick container) proposed in Japanese Utility Model Application No. 63-78346.
As shown, this cosmetic material container is
And a container body 102 to which the cartridge 101 is detachably mounted. The cartridge 101 includes a cartridge body 103 and a push rod (rod body) 1.
04 and a return spring 105.

[0004] The push rod 104 is accommodated in the cartridge body 103 so as to be strokeable in the axial direction. A cosmetic holding member 106 at the tip of the push rod 104 holds a stick-shaped cosmetic 107 coaxially. Further, a screw groove (spiral groove) 108 is cut in the inner peripheral surface on the base end side of the cartridge main body 103, and the protrusion 109 at the base end of the push rod 104 is engaged with the screw groove 108. Further, a shaft rod 111 erected coaxially from the bottom surface of the container body 102 is inserted into a coaxial insertion hole 110 formed coaxially with the push rod 104, and is spline-coupled (movable in the axial direction and rotatable rotatably). Join.

[0005] As described above, the cartridge type cosmetic material container includes the container main body 102, the cartridge main body 103, the push rod 104, and the return spring 105 as main components. Then, with the cartridge 101 attached to the container body 102, the cartridge body 103
When the container and the container body 102 are relatively rotated, the protrusion 109 of the push rod 104 is guided along the thread groove 108, and as a result, the push rod 1
04 strokes on the axis of the cartridge body 103,
Cosmetic 107 is paid out from opening 112. Further, when the cartridge 101 is removed from the container body 102 in a state in which the cosmetic 107 is drawn out, the push rod 104 is pushed back to the lower limit of the stroke by the return spring 105, and the cosmetic 107 is automatically drawn into the opening 112 ( Auto return).

[0006]

However, in such a conventional cosmetic material container, the push rod 104 is fitted to the push rod 104 so as to be axially movable and rotatably coupled to the container body 102 as described above. In addition to forming the insertion hole 110, it is necessary to erect the shaft rod 111 having a length at least as long as the stroke of the push rod 104 in the container body 2. For this reason, the configuration of the container body 2 becomes complicated, and
It is necessary to increase the diameter of the push rod 104 and, consequently, the cartridge body 103, so that a cosmetic material container that can be adapted to a small-diameter rod-shaped cosmetic cannot be constructed.

[0007] Further, the cosmetic material 107 is
Since the push rod 104 rotates with respect to the cartridge main body 103 when the push rod 104 is moved inside, the push rod 104 and the cosmetic material holding member 106 are constituted by one member. The cosmetic 10 will be drawn into the main body 103.
7 tends to be unstable. The cross-sectional shape that the cosmetic 107 can take is limited to a circular shape, and various restrictions on the design arise, such as a design that obliquely cuts the tip of the cosmetic material 107 and the cosmetic material container cannot be adopted. .

When the cosmetics 107 are mounted on the cosmetic material holding member 106 after the cartridge 101 is assembled, the cosmetics holding member 106 is drawn out toward the opening 112 and the cosmetics holding member 106 is inserted into the cosmetics holding member 106. The cosmetics 107 attached in this case
If the cosmetics 107 are drawn into the main body of the cartridge 103 while rotating, the cosmetic 107 may be damaged or broken. For this reason, after the push rod 104 and the cosmetic material holding member 106 are composed of separate rotatable members (two members),
It is necessary to make the makeup material holding member 106 and the cartridge body 103 non-rotatable, which complicates the configuration of the makeup material container, and takes much time for assembly.

Further, the user of the cosmetic material container may want to confirm the type (color) and remaining amount of the stick-shaped cosmetic material when the cartridge is used alone (with the cartridge removed from the container body). In the case of the cosmetic material container described above, the cosmetic 107 cannot be fed out in the state of the cartridge 101 alone.

The present invention has been made in view of such a problem. In a cartridge or a cartridge type cosmetic material container in which a cosmetic material is automatically returned by removing the cartridge, the structure of the container body can be simplified. It is an object of the present invention to provide a material that can be applied to a small-diameter cosmetic material and has a stable auto return operation.

[0011]

According to a first aspect of the present invention, there is provided a cartridge which is removably mounted on a container body and accommodates and holds a stick-shaped cosmetic material therein. In a cosmetic material container cartridge for moving a cosmetic material forward and backward, a front cylinder provided with the front end opening,
A cylindrical body rotatably mounted on the base end side of the front cylinder,
The cartridge main body is composed of the front cylinder and the cylindrical body, a rod body is housed in the cartridge main body, and a cosmetic material holding portion for holding the rod-shaped cosmetic material is formed at a tip side of the rod body, The side is provided with a sliding mechanism that makes the rod body non-rotatable with respect to the front cylinder and slidable in the axial direction, and the cylinder side is provided with a feeding mechanism by screwing the rod body and the cylinder, An urging means for urging the rod body in a lower limit direction of a stroke is provided, and a synchronous engaging means for non-rotatably engaging the cylindrical body and the container body is provided.

[0012] In the second invention, the feeding mechanism includes a spiral portion formed on the outer periphery of the rod body and a spiral groove formed on the peripheral surface of the cylindrical body and partly engaging with the spiral portion.

In the third 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 the fourth aspect, the engaging portion of the sliding mechanism is formed on the outer periphery of the decorative material holding portion.

In a fifth 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 sixth aspect, the engaging portion of the sliding mechanism is formed below the decorative material holding portion, and the sliding portion is formed on the inner peripheral surface of the small diameter portion formed on the base end side of the front cylinder. Is formed.

In the seventh invention, the helical portion formed on the outer periphery of the rod body is a plurality of engaging projections arranged on a straight line extending in the axial direction, and these engaging projections are formed by the sliding mechanism. When it is extended to the sliding portion side, it becomes an engaging portion that engages with this sliding portion.

In the eighth invention, the urging means for urging the rod body in the lower limit direction of the stroke is constituted by a coil spring disposed on the outer periphery of the rod body, and the coil spring is provided on the cylinder side. Between the lower step and the upper step provided on the rod body side.

According to a ninth aspect of the present invention, there is provided a resistance applying means for applying a resistance to the rotation of the tip cylinder and the container body, and the resistance of the resistance applying means is such that the coil spring is turned when the coil spring contracts. It was set to be larger than the repulsive force for rotating the cylinder and the container body in the reverse direction.

In the tenth aspect, the resistance applying means is constituted by an O-ring disposed between the outer periphery of the front cylinder and the inner periphery of the container body.

[0021] In the eleventh invention, the rod body has a non-projection portion on the base end side of the rod body where the spiral portion does not exist, and the rod body has been stroked to a position where the non-projection portion faces the spiral groove. However, the upper limit of the stroke of the rod was set.

According to a twelfth aspect of the present invention, in a cosmetic material container, there is provided a cartridge according to any one of the first to eleventh aspects, and a container main body in which the cartridge is removably accommodated. When housed in the container, the front cylinder is rotatable with respect to the container main body, while the synchronous engagement means connects the cylinder with the container main body so as to be non-rotatable.

According to a thirteenth aspect, the synchronous engagement means includes:
A spline portion is formed on the outer peripheral surface of the cylindrical body and the inner peripheral surface of the container body, and spline-connects the cylindrical body and the container body.

[0024]

According to the present invention, when the stick-shaped decorative material is unwound 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 rotation of the rod and the front cylinder is inhibited by the sliding mechanism, and the rotation of the cylinder and the container body are inhibited by the synchronous engagement means, 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 into the decorative material container, the front cylinder and the container main 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 while the stick-shaped cosmetic material is extended, 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 drawn into the front cylinder. (Auto return).

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 strokes in a smooth and stable operation, even when the rod-shaped decorative material automatically returns, an accident such as breakage of the rod-shaped decorative material is unlikely to occur.

Further, since the cylindrical body is attached to the base end side of the front cylinder, even when the cartridge is a single unit, the operator rotates the cylindrical body and the front cylinder to draw out the rod-shaped decorative material, and the rod-shaped decorative material is drawn out. You can check the type (color) and remaining amount of the material. Therefore, even when there are a plurality of cartridges for one container main body, it is not necessary to attach each cartridge to the container main body for checking the stick-shaped decorative material, which is convenient. After this confirmation, the stick-shaped decorative material is automatically returned into the cartridge by the action of the urging means. Therefore, since the stick-shaped decorative material does not remain unnecessarily fed out of the cartridge, the risk of the stick-shaped decorative material being broken or soiled can be reduced.

In the present invention, since the container body is connected to the cylinder via the synchronous engagement means, the rod-shaped decorative material automatically returns when the cartridge is pulled out from the container body. Regardless, the configuration of the container body can be simplified. For example, if the synchronous engagement means is constituted by a spline mechanism as in the thirteenth aspect, the structure 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 reduced. 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 the rod body does not need to be provided with a hole for coupling to the container main body, it can be made to have a small diameter, and accordingly, the diameter of the cartridge main body can be made sufficiently small. Therefore, a cosmetic material container suitable for a small-diameter rod-shaped decorative material can be easily configured.

Further, since the rod body is housed in the cartridge main body having the cylindrical body attached to the base end of the front cylinder, when the rod-shaped cosmetic material is mounted on the cosmetic material holding portion at the tip of the rod body after assembling the cartridge, the rod body is required. For example, the base end side of the cylindrical body may be pushed out from the opening of the base end of the cylindrical body with a rod-shaped member, and the cosmetic material holding portion may be brought to the front cylinder opening side. If removed, the stick-shaped decorative material is accommodated in the cartridge body without rotating with respect to the front cylinder, and there is no fear that the stick-shaped decorative material is broken or damaged.

Further, as in the fifth invention, the decorative material holding portion may be constituted by nail pieces, and the rod-shaped decorative material may be supported from the side by the inner peripheral surface of the front cylinder between the nail pieces. Further, it is possible to securely hold the rod-shaped decorative material while minimizing the cartridge diameter, and to prevent the rod-shaped decorative material from being broken during a stroke even if the rod-shaped decorative material has a small diameter.

Further, as in the seventh invention, when the engaging projection of the spiral portion is sequentially engaged with the sliding portion of the sliding mechanism when the rod body makes a stroke, the diameter of the cartridge can be reduced. It can be extremely thin.

Further, in the eighth invention, the biasing means is a coil spring disposed on the outer periphery of the rod body, and is interposed between a downward step provided on the cylinder side and an upward step provided on the rod body. Therefore, the urging means can be simply configured, and can be easily incorporated into the cosmetic material container.

If the resistance force of the resistance applying means is set to be larger than the repulsion force of the coil spring at the time of the most contraction as in the ninth invention, the coil spring contracts with the stroke of the rod body. Even if the repulsive force increases, the front cylinder does not reversely rotate, and the rod-shaped decorative material is stabilized at the extended position.

In the tenth aspect, the resistance applying means is constituted by the O-ring disposed between the outer circumference of the front cylinder and the inner circumference of the container main body. It can be constructed at low cost, and the resistance applying means can be easily assembled. The O-ring also acts to suppress the wobble of the front cylinder, and the operation of the cartridge is stabilized.

According to the eleventh aspect, when the rod stroke reaches the upper limit defined by the non-projecting portion formed on the rod body,
The engagement between the spiral portion and the spiral groove is released, the cylinder body and the rod body idle, and the rod body does not further stroke. Therefore, the rod body will not be unnecessarily stroked. For example, when the urging means is formed of a coil spring as in the seventh invention, the coil spring is compressed beyond the compression limit, and is broken. It will not be lost. Further, when the rod body stroke reaches the upper limit, a clutch sound is generated due to the idle rotation of the cylinder and the rod body, so that the operator of the cosmetic material container can know from the clutch sound that the feeding has reached the upper limit. .

[0037]

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

FIG. 1 shows a cosmetic container according to a first embodiment of the present invention.

As shown, the cosmetic material container comprises a cartridge 1 and a container body 2 to which the cartridge 1 is detachably mounted. The cartridge 1 accommodates the stick-shaped decorative material 4 so as to be able to be fed out.
0, a cylindrical body 20, a rod body (push rod) 30, and a return spring 6.

The front cylinder 10 is a cylindrical member that constitutes the front end of the cartridge 1.
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 drawn out of the opening 12 at the tip of the front cylinder 10 so as to be freely retractable.

On the other hand, the proximal end portion of the front cylinder 10 is a proximal end portion 13 having a slightly smaller outer diameter than the distal end side. When the cartridge 1 and the container body 2 are connected to each other,
The portion is removably accommodated in the container main body 2 from the upper opening of the container main body 2 together with the cylindrical body 20. In this case, by fitting the annular fitting projection 14 on the outer circumference of the base end 13 of the front cylinder and the annular fitting recess 41 formed on the inner peripheral surface of the container body 2, the front cylinder 10 and the container body 2 is positioned so as to be immovable (impossible to come out) in the axial direction, and is rotatable along the fitting convex portion 14 and the fitting concave portion 41 in the rotating direction.

The upper end of the cylindrical body 20 is housed inside the base end portion 13 of the front cylinder, and the cylindrical body 20 and the front cylinder 10 constitute a cartridge body. In this case, the fitting projection 21 formed at a predetermined position on the outer peripheral surface of the cylindrical body 20 fits into the fitting concave portion 15 formed on the inner peripheral surface of the front cylinder 10. 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.

A predetermined length of the upper end side (the side accommodated in the front cylinder 10) of the cylinder 20 is a spiral cylinder portion 22 having a small inner diameter. A spiral groove 23 is cut in the inner peripheral surface of the spiral tube portion 22, and a plurality of engagement protrusions 35 on the outer periphery of a rod 30 described later are screwed into the spiral groove 23. Further, a portion from the lower end 22A of the spiral cylinder 22 to the lower end of the cylinder 20 is an extension 24 having an inner diameter larger than that of the spiral cylinder 22.

A synchronous engaging portion 26 formed of a plurality of female splines extending in the axial direction is formed on the outer peripheral surface of the lower end portion of the cylindrical body 20. When the cartridge 1 is mounted on the container body 2, the spline portion 26 is spline-coupled to a spline portion 45 formed of a male spline formed on the inner peripheral surface on the bottom 42 side of the container body 2. This allows
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.
And the cylindrical body 20 rotates.

A ring groove 18 is formed at a predetermined position on the outer peripheral surface of the base end 13 of the front cylinder.
An O-ring 5 is fitted as a resistance applying means. Thus, when the cartridge 1 is mounted on the container main body 2 and the stick-shaped decorative material 4 is fed, the O-ring 5 gives a frictional resistance to the rotation of the front cylinder 10 and the container main body 2, and the cartridge 1
Appropriate weight is given to the rotation operation of the
The wobble during the rotation of 0 is eliminated, and the operation of the cartridge 1 is stabilized.

The frictional resistance of the O-ring 5 is such that even if a return spring 6 described later contracts with the stroke of the rod 30, the return spring 6 may rotate the front cylinder 10 and the cylinder 20 in the reverse direction. It is set to continue to be larger than the repulsive force. Therefore, the front cylinder 10 is not reversely rotated by the return spring 6 from the rotated position.

The cartridge body (the front cylinder 10 and the cylinder 2
The rod 30 is coaxially accommodated in the inside of 0). The rod body 30 can be stroked in the axial direction in the cartridge main body, and the rod-shaped decorative material 4 held coaxially by the cosmetic material holding portion 31 on the tip side (opening 12 side) of the rod body 30 includes:
With this stroke, it is fed out from the front cylinder opening 12.

More specifically, the cosmetic material holding section 31
The rod-shaped decorative material 4 includes a base portion 32 and a holding tube 33 extending from the base portion 32 toward the opening 12, and the base end is housed and held in the holding tube 33. Also, as shown in FIG.
The base 32 and the holding cylinder 33 have an elliptical cross-section, and as described above, are fitted to the cosmetic material accommodating hole 11 also having an elliptical cross-section so as to be slidable in the axial direction and non-rotatably.
That is, in the present embodiment, the cosmetic material holding portion 31 and the cosmetic material housing hole 11 themselves serve as an engaging portion and a sliding portion of the sliding mechanism, respectively. The cosmetic material holding portion 31 and the cosmetic material accommodation hole 11
The different-diameter fitting of is not limited to an elliptical shape, for example, a polygonal different-diameter fitting, or engagement by a sliding protrusion, etc.
It can take various forms.

On the outer periphery of the rod body 30, a plurality of helical portions are formed from a portion immediately below the base 32 of the decorative material holding portion 31 to a portion immediately before a spring seat member 34 described below and before a non-projecting portion 36. Are formed. The group of the engagement projections 35 are linearly arranged in the axial direction, and are arranged (arranged along the spiral track) in conformity with the spiral groove 23 of the spiral cylinder portion 22 described above. A part of these engaging projections 35 is screwed into the spiral groove 23 in accordance with the above. The spiral groove 23 and the plurality of engagement protrusions 35 constitute a feeding mechanism for feeding the rod-shaped decorative material 4. That is, when the front cylinder 10 (the rod 30) and the cylinder 20 rotate relative to each other, the plurality of engagement protrusions 35 of the rod 30 are sequentially screwed into the spiral grooves 23 and guided, and the rod 30 is 2
It will be fed from 0.

In this case, 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. Further, when the rod body 30 is stroked upward to a position where the non-projection portion 36 is opposed to the spiral cylinder portion 22, the engagement between the engagement projection 35 and the spiral groove 23 is released, and even if the front cylinder 10 is rotated, The body 30 no longer strokes. Therefore, this stroke position is
Is the upper limit of the stroke. The upper limit of this stroke is set so that a return spring 6 described later does not contract beyond the contraction limit.

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.

An annular spring seat member 34 is provided on the outer periphery of the locking portion 37 near the base end of the rod 30. A return spring 6 composed of a coil spring is provided between the spring seat member 34 (upward step) and the lower end 22A (downward step) of the helical cylinder 22 and is disposed on the outer periphery of the rod 30. . The rod 30 is always urged toward the lower end of the cylindrical body 20 by the return spring 6. Thus, when the cartridge 1 is removed from the container body 2 and the resistance to the relative rotation of the front cylinder 10 and the cylindrical body 20 by the O-ring 5, that is, the resistance to the stroke of the rod body 30 is released, the rod body 30 Pulled back to the lower limit, the stick-shaped decorative material 4 is automatically stored in the cartridge.

The cartridge 1 is constructed as described above. In assembling the cartridge 1, for example, first, the rod 30 is inserted into the opening on the distal end side of the cylindrical body 20 while screwing the base end side thereof. The rod 30 is incorporated in the cylinder 20. Then, the return spring 6 is inserted from the base end side of the cylindrical body 20 and arranged on the outer periphery of the rod body 30, the spring seat member 34 is attached to the locking portion 37 of the rod body 30, and the return spring 6 is connected to the lower end of the spiral cylindrical part. It is sandwiched between 22A and the spring seat member 34. The cylindrical body 20 incorporating the rod body 30
Is inserted from the base end side opening of the front cylinder 10 so that the cosmetic material holding portion 31 is accommodated in the cosmetic material accommodation hole 11, and the fitting projection 21 on the outer periphery of the cylinder 20 is fitted on the inner periphery of the front cylinder 10. Push the cylinder 20 and the rod 30
To incorporate. Further, O is inserted into the ring groove 18 on the outer periphery of the front cylinder 10.
The cartridge 1 is completed by fitting the ring 5.

When the cartridge 1 is to be mounted on the container body 2, the cartridge 1 is inserted into the upper opening of the container body 2 from the side of the cylinder 20. Thereby, the cylinder 2
The spline portion 45 of the container body 2 is fitted to the spline portion 26 at the base end, and the fitting protrusion 14 on the outer peripheral surface of the front cylinder 10 is fitted.
Are fitted into the fitting recesses 41 on the inner peripheral surface of the container body 2,
Numeral 0 is easily mounted rotatably on the container body 2, and the cylinder 20 is automatically non-rotatably mounted on the container body 2.

Next, the operation will be described.

When the stick-shaped decorative material 4 is to be unwound from the cartridge 1, the front cylinder 10 of the cartridge 1 is rotated in a predetermined forward direction with respect to the container body 2. Then, the rod body 30 engaged with the front tube 10 via the sliding mechanism (the fitting of the cosmetic material holding portion 31 and the cosmetic material housing hole 11 with different diameters) rotates synchronously with the front tube 10. On the other hand, since the cylinder 20 spline-coupled to the container body 2 does not rotate, the cylinder 20 and the rod 30 eventually rotate relative to each other. Thereby, the plurality of engaging projections 3 of the rod 30
5 is screwed into the spiral groove 23 of the spiral cylinder portion 22 sequentially, so that the rod 30 is extended from the tip end side of the cylinder 20.

In this case, as described above, the rod 30
Is engaged with the front cylinder 10 via the sliding mechanism, and therefore strokes in the axial direction without rotating with respect to the front 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.

Further, since a suitable resistance is given to the rotating operation of the front cylinder 10 (stroke of the rod 30) by the urging force of the return spring 6 and the frictional resistance of the O-ring 5, the rotating operation (stroke) is It will be stable.

Even when the return spring 6 contracts with the stroke of the rod 30, the frictional resistance of the O-ring 5 is reduced by the contracted return spring 6.
It is set so as to continue to be larger than the repulsive force to be rotated in the reverse direction. Therefore, the front cylinder 10 is connected to the container body 2.
When the stick-shaped cosmetic material 4 is unwound by rotating it manually,
The front cylinder 10 is held at its rotational position by the frictional resistance of the O-ring 5, so that the stick-shaped decorative material 4 is not drawn into the decorative material container.

When the rod 30 is stroked to a position where the non-projecting portion 36 is opposed to the spiral groove 23, the front cylinder 10
Even if the container body 2 is rotated, the cylindrical body 20 and the rod body 30 rotate idly, and the rod body 30 does not further stroke.
Therefore, the rod body 30 is stroked more than necessary,
The return spring 6 is not compressed beyond the compression limit and is not broken. When the rod 30 reaches the upper limit of the stroke as described above, the cylindrical body 20 and the rod 30
The idle sound causes a clutch sound, so that the operator of the cosmetic material container can know from the clutch sound that the feeding has reached the upper limit.

On the other hand, when it is desired to pull back the rod-shaped decorative material 4 into the cartridge 1, the front cylinder 10 and the container main body 2 are rotated in the opposite direction to that at the time of feeding. As a result, the rod 30 strokes in the stroke lower limit direction, and as a result, the rod-shaped decorative material 4 is drawn into the front cylinder 10. Alternatively, the cartridge 1 is removed from the container body 2. As a result, the frictional resistance of the O-ring 5 acting between the front cylinder 10 and the container body 2 disappears, so that the rod 30 is pulled back to the lower stroke limit by the urging force of the return spring 6, and the rod-shaped decorative material 4 is drawn inside the front cylinder 10.

In these cases, the cylindrical body 20 rotates in the reverse direction with respect to the front cylinder 10, but since the rod-shaped decorative material holding portion 31 does not rotate with respect to the front cylinder 10, the rod-shaped decorative material 4 is not rotated. It is drawn in without rotating.

The rod-shaped decorative material 4 (the rod 3
The upper and lower limits of the stroke of 0) are as follows: the stroke position where the non-projection portion 36 faces the spiral tube portion 22 and the stroke position where the decorative material holding portion base 32 abuts on the cylindrical body upper end 20A.
Since each is set, the stroke of the rod-shaped decorative material 4 is stably performed, and the rod 30 is not stroked upward beyond the contraction limit of the return spring 6.

FIG. 3 shows a cartridge 50 according to a second embodiment of the present invention.

The cartridge 50 is housed in the container body 2 (see FIG. 1) having the same configuration as that of the first embodiment, and forms a cosmetic material container. Further, the cartridge 50 is the cartridge 1 of the first embodiment.
This is common to the basic configuration of FIG. 1 (see FIG. 1), and is different only in the configuration of the rod 30 and the configuration of the cosmetic material receiving hole 11 of the front cylinder 10. Therefore, in FIG. 3, configurations having the same functions as those in the first embodiment are denoted by the same reference numerals, and the configuration that is a feature of the present embodiment will be mainly described.

As shown in the figure, the cosmetic material holding portion 31 of the rod 30 includes a base portion 32 and four claw pieces 51 erected upward from the side of the base portion 32. . The nail pieces 51 are arranged at intervals of about 90 degrees, and the stick-shaped decorative material 4 is held substantially coaxially with the front cylinder 10 so as to be surrounded by the nail pieces 51.

Corresponding to the claw pieces 51, four engaging grooves 52 extending in the axial direction are formed on the inner peripheral surface of the cosmetic material accommodating hole 11.
Are formed at an interval of about 90 degrees from each other. And
The four claw pieces 51 are respectively engaged with the corresponding engagement grooves 52, and the decorative material holding portion 31 is guided in the axial direction along the engagement grooves 52. As a result, the cosmetic material holding section 31
Stroke in the axial direction without rotating. That is, in the present embodiment, a sliding mechanism is constituted by the engaging groove 52 and the claw piece 51, and the engaging groove 52 is formed by the sliding portion of the sliding mechanism, and the claw piece 51 is formed by the engaging portion of the sliding mechanism. Become.

The protrusion width in the cartridge radial direction of the portion of the claw piece 51 that holds the rod-shaped decorative material 4 is larger than the protrusion width in the cartridge radial direction of the portion fixed to the base 32.
It may be equal or smaller as shown. Thereby, the stick-shaped decorative material 4 of the nail piece 51
A large load is not applied to the portion for holding the stick, and as a result, it is possible to prevent the stick-shaped decorative material 4 from being broken or coming off the nail piece 51.

Further, on the inner peripheral surface of the cosmetic material accommodation hole 11,
The four regions sandwiched between the engagement grooves 52 become sliding surfaces 53. The stick-shaped decorative material 4 held by the decorative material holding portion 31 is provided with sufficient support from the sides by the sliding surfaces 53 between the claw pieces 51.

A plurality of engaging projections 55 are formed on the rod body 30 on four straight lines extending in the axial direction below each of the four claw pieces 51. As shown in FIG. 4, these engagement projections 55 are arranged along a spiral track (a track that can be screwed into the spiral groove 23) as a whole.

The shape of the inner peripheral surface of the cosmetic material accommodating hole 11 is set substantially equal to the outer diameter of the engaging projection 55 of the rod 30. Further, the engagement protrusion 55 is formed to extend in the width direction so as to have a width substantially equal to the width of the engagement groove 52,
The elliptical shape follows the spiral orbit.

With such a configuration, as shown in FIG. 5, when the rod 30 strokes toward the cosmetic material receiving hole 11 side, the engaging protrusions 55 In order without any gap in the rotation direction. That is, when the engagement protrusion 55 is extended into the cosmetic material accommodation hole 11, the engagement protrusion 55 functions as an engagement portion of the sliding mechanism.

Thus, in the cartridge 50 of the present embodiment, the stroke of the rod 30 can be further stabilized, and when a load in the torsional direction is applied to the cartridge 50, the rod 30 The cosmetic material container resistant to the load in the torsional direction can be constituted by the amount supported by 55, and the load on the nail pieces 51 can be reduced.
Therefore, the cartridge 50 according to the present embodiment is suitable for the soft rod-shaped decorative material 4 which has a smaller diameter and is softer than the cartridge 1 according to the first embodiment. If it is desired to more stably hold the stick-shaped decorative material 4, the width of the nail pieces 51 may be increased as necessary.

In this embodiment, as a spring seat member, a C-ring 57 is locked to the base end portion of the rod body 30, and the upward step portion of the flange portion 57 A and the lower end portion of the spiral tube portion of the C-ring 57. The return spring 6 is mounted between the return spring 22 and the base 22A.

FIG. 6 shows a cartridge 60 according to a third embodiment of the present invention.

The cartridge 60 is also accommodated in the container body 2 having the same configuration as that shown in FIG. 1 and constitutes a cosmetic material container. The cartridge 1 of the first embodiment (FIG. 1) Only the configuration of the front cylinder 10 is different from that of the first embodiment. Therefore, in FIG. 6, the configurations having the same functions as those in the first embodiment are denoted by the same reference numerals, and in the following description, the configurations different from those in the first embodiment will be mainly described.

In this embodiment, a small-diameter portion 61 having an inner diameter substantially equal to the outer diameter of the rod body 30 is formed in front of the base end of the front cylinder 10, and at the lower limit of the stroke of the rod body 30, the cosmetic material holding section 31 is formed. The base 32 is adapted to contact the upper end surface 61B of the small diameter portion 61.

Further, four sliding grooves 62 are formed on the inner peripheral surface of the small diameter portion 61 at positions corresponding to the four straight lines on which the engaging projections 35 are formed on the rod 30. A part of the plurality of engaging projections 35 engages with these sliding grooves 62. Thereby, the sliding groove 62 and the engaging projection 35 engaged with the sliding groove 62 act as a sliding mechanism,
The rod 30 is guided in the axial direction so as not to rotate with respect to the front cylinder 10.

Further, according to the present embodiment, the small diameter portion 61
The cosmetic material accommodating hole 11 is defined by the above, so that when the liquid cosmetic material material is filled in the cosmetic material accommodating hole 11 to form the rod-shaped decorative material 4, the cosmetic material material does not easily flow out to the cylindrical body 20 side. . Therefore, the production efficiency of the cosmetic material container can be improved.

As described above, according to the present invention, in a cartridge type cosmetic material container capable of auto return, the cartridge main body is divided into the front cylinder 10 and the cylindrical body 20, and the cylindrical body 20 is provided with the spiral cylindrical portion 22. The rotation of the front cylinder 10 and the container body 2 causes the stick-shaped decorative material 4 to be fed out.

Therefore, the spline portion 45 may be formed in the container main body 2 as a synchronous engagement means for inhibiting rotation with respect to the cylindrical body 20, for example, as in the above-described embodiment. Can be simplified. In particular, when the synchronous engagement means is constituted by a spline, the container main body 2 can have a simple structure in which the spline portion 45 is formed on the bottom portion 42 side of the cylindrical member. And the manufacturing cost can be reduced.

Further, since the rod 30 can have a small diameter, the diameter of the cartridge 1 can be made sufficiently small, and a makeup material container suitable for the small-diameter rod-shaped makeup material 4 can be easily constructed. In particular, as in the second embodiment, the stick-shaped decorative material 4 is held by a plurality of nail pieces 51 and these nail pieces 5
1 and the engaging groove 52, a sliding mechanism is formed, and when the rod 30 makes a stroke, the engaging protrusions are sequentially engaged with these engaging grooves 52.
Can be extremely thin.

Further, since the rod-shaped decorative material 4 does not rotate with respect to the front cylinder 10 at the time of feeding out from the front cylinder 10 or also at the time of automatic return, the rod-shaped decorative material 4 rapidly
Even when the stick-shaped decorative material 4 is drawn in, the stick-shaped decorative material 4 strokes in a smooth and stable operation. Therefore, an accident such as breakage of the rod-shaped decorative material 4 during the automatic return is unlikely to occur.

Further, since the cylindrical body 20 is attached to the base end side of the front cylinder 10, even when the cartridge 1 is used alone (even when the cartridge 1 is detached from the container body 2), the operator is not required. By rotating the cylindrical body 20 and the front cylinder 10, the rod-shaped decorative material 4 is paid out, and the type (color) and the remaining amount of the rod-shaped decorative material 4 can be confirmed. Therefore, even when there are a plurality of cartridges 1 to be attached to one container body 2, it is not necessary to attach the cartridge 1 to the container body 2 every time to check the stick-shaped decorative material 4, which is convenient. After this confirmation, the rod-shaped decorative material 4 is automatically returned into the cartridge 1 by the action of the return spring 6. Therefore, the stick-shaped decorative material 4
Is not unnecessarily fed out of the cartridge 1, so that the risk that the stick-shaped decorative material 4 is broken or becomes dirty can be reduced.

The rod 30 is attached to the base end of the front cylinder 10.
When the rod-shaped decorative material 4 is attached to the cosmetic material holding portion 31 at the tip of the rod 30, the base end of the rod 30 is, for example, rod-shaped through the opening at the base end of the cylindrical body 20. It is only necessary to push the decorative material holding portion 31 toward the front tube opening 12 side by pushing out the member. And
After the rod-shaped decorative material 4 is mounted, if the rod-shaped member is removed, the rod-shaped decorative material 4 is accommodated in the cartridge body without rotating with respect to the front cylinder 10. Therefore, the assembly process of the cartridge 1 can be greatly simplified, and the manufacturing cost can be reduced.

In the first to third embodiments,
Assuming that the container main body 2 is made of, for example, a resin (when spline processing is easily performed), the container main body 2 and the cartridge 1 or 50 are connected via the spline. Is not limited to such a form. For example, when the container body 2 is made of metal, the container body 2 and the cartridge 1 or 50 can be connected via a spring member (wig spring). Even in this case, the container main body 2 can have a very simplified configuration, and the cartridge main body can have a small diameter suitable for the small-diameter rod-shaped decorative material 4.
