A spiral cylinder 60 that is rotatably but irremovably fitted into the guide cylinder 58 and that has a spiral groove 59 that is screwed into the screw engagement projection 55.
And a sleeve 62 having a length that covers the guide cylinder 58 and is inserted into the outer periphery of the spiral cylinder 60 on the top surface, and the engagement is provided on the inner wall of the lower end of the guide cylinder 58. It has a basic structure in which a stop cylinder 53 is stored and held. A locking step portion 63 is formed on the inner wall surface of the locking cylinder 53, and a flange portion 64 having a diameter substantially the same as the outer diameter of the sleeve 62 is provided around the lower end outer circumference thereof, and the bottom surface thereof. A meshing portion 65 is provided on the uneven surface.

The locking mechanism 54 is mounted on the outer periphery of the cam shaft 66 such that the cam shaft 66 has a large-diameter portion 66a at its tip (upper end) protruding from the bottom of the decorative tubular body 52 and is vertically movable. Locking tube on top

[Problems to be Solved by the Invention] According to such a stick-shaped cosmetic container, since the attachment / detachment operation with respect to the makeup cylinder 52 can be performed by vertically sliding the feeding container body 51, the stick-shaped cosmetic 50 can be easily replaced. In addition, by increasing the quality of the makeup cylinder 52, it is possible to give a high-grade feeling to the entire stick-shaped cosmetic container. However, in such a stick-shaped cosmetic container, the structure is still complicated,
There was a problem to be solved that the man-hours for assembling were large and the cost was unsatisfactory.

The present invention has been proposed in view of the above circumstances, and it is an object of the present invention to provide a stick-shaped cosmetic container that has the effect of easily exchanging the stick-shaped cosmetic and can reduce the cost by simple manufacturing.

[Means for Solving the Problems] In the present invention, therefore, a spiral tube having a spiral groove formed on the inner periphery thereof, and a guide tube having a long hole rotatably inserted into the spiral tube and extending in the axial direction are formed. And a feeding tray body that is movably inserted in the guide tube and has a tray formed on the outer peripheral portion with a projection that engages with the spiral groove of the spiral tube through the long hole of the guide tube and the feeding container body. Of the guide cylinder of the present invention, which is integrally fitted into the guide cylinder so as to cover the outer periphery of the guide cylinder, and a cylindrical fitting cylinder is provided at the bottom of the decorative cylinder along the axial direction of the cylinder and the fitting is provided. At least a pair of protrusions extending in the circumferential direction of the fitting cylinder are provided at opposite positions on the outer peripheral surface of the cylinder, and outer surfaces in the protruding direction of the paired protrusions are formed in parallel to each other. A fitting hole is formed in the bottom of the guide cylinder so that the fitting cylinder fits into the fitting cylinder. The inner wall surface of the fitting hole is provided with a protrusion that engages with the lower edge of the protrusion when the feeding container body is rotated in the circumferential direction, and that restricts movement of the feeding container body in the axial direction. The inner wall surface of the fitting hole is set so as to make surface contact with the outer surface of the ridge when the ridge and the protrusion are in an engaged state.

Here, if one end of the protrusion is formed to be bent and the one end is brought into contact with the end portion of the protrusion to restrict the rotation of the feeding container body, the inner wall surface of the fitting hole and the protrusion are formed. Since the rotation of the feeding container body is restricted at the time of surface contact with the outer surface of the above, it is possible to prevent the excessive movement at the time of rotation, which is preferable.

On the other hand, it is preferable that the ridge is formed so as to descend as it extends in the circumferential direction of the fitting cylinder, because the ridge and the protrusion can be screwed together.

"Operation" Since the fitting cylinder in the makeup cylinder is formed in a cylindrical shape and the ridges are provided at the opposite positions on the outer peripheral surface thereof, simply inserting the guide cylinder of the feeding container body into the makeup cylinder, The projection of the fitting hole and the ridge of the fitting tube engage with each other by simply inserting the fitting tube inside the decorative tube into the fitting hole at the bottom of the guide tube and slightly rotating the feeding container body. Then, the feeding container body is mounted, and the movement of the feeding container body in the axial direction is regulated to prevent the feeding container body from falling off from the cosmetic cylinder body. The inner wall surface of the fitting hole of the guide cylinder comes into surface contact with each other, and the loosening preventing action of the feeding container body occurs. Also, when removing the feeding container body, the feeding container body can be detached from the makeup cylinder simply by rotating the feeding container body in the opposite direction and raising it.

Here, when the feeding container body is mounted, if the pushing operation of the feeding container body is performed when the protrusions and the protrusions are in the same position, the elastic deformation action of the peripheral wall of the fitting hole to the outside is performed. As a result, the projections on the inner wall of the fitting hole pass over the projections on the outer circumference of the fitting cylinder, so that the projections and the projections are engaged with each other, and the delivery container body is in the mounted state.

[Embodiment] A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In these drawings, reference numeral 1 is a feeding container body, reference numeral 2 is a makeup cylinder body for accommodating and holding the feeding container body 1, and these reference numerals 1 and 2 constitute a main member of the stick-shaped cosmetic container.

Next, these will be described in detail. The feeding container body 1 is one in which the stick-shaped cosmetic material 3 is housed inside and fed out, and the structure thereof is widely and conventionally used for lipsticks and the like. It is almost the same. That is, the spiral cylinder 11 having the spiral groove 10 formed on the inner periphery thereof, the guide cylinder 13 rotatably inserted into the spiral cylinder 11 and having the elongated hole 12 extending in the axial direction, and the guide cylinder 13 It is movably inserted, and is configured mainly with a saucer 15 on the outer peripheral portion of which a projection 14 that engages with the spiral groove 10 of the spiral cylinder 11 is formed through the long hole 12 of the guide cylinder 13, and the spiral cylinder 11 and the guide. The pan 15 is moved up and down in the guide cylinder 13 by rotating the cylinder 13 relative to each other. A sleeve 16 is attached to the outer circumference of the spiral cylinder 11 to cover the outer circumference.

However, in the present invention, a locking portion is provided at the bottom of the guide cylinder 13 of the feeding container body 1 so that it can be engaged with the decorative cylinder body 2, and the configuration of these engaging portions is maximum. The feature is that the configuration is different from the conventional feeding container.

First, a description will be given of the makeup cylinder 2 that stores and holds the feeding container body 1. This is a cylindrical outer circumference 20 having a bottom and a bottom plate of the outer circumference 20 which is arranged along the axial direction of the outer circumference 20. A cylindrical fitting tube 21 for locking the feeding container body 1,
It is mainly composed of a coupling cylinder 22 for coupling the cap that positions the fitting cylinder 21 in the outer cylinder 20.

The outer cylinder 20 is provided on the outer circumference thereof to enhance the aesthetic appearance of the container, and the fitting cylinder 21 provided in the outer cylinder 20 is located at a position where the outer peripheral surface thereof faces. Then, two pairs of protrusions 23, 23 extending in the circumferential direction of the fitting cylinder 21 are provided. These ridges 23, 23 are the fitting tube 2 in the illustrated example.
Protrusions that are located at four equal positions in the circumferential direction of 1 and that protrude along the radial direction of the fitting cylinder 21 and are a pair thereof.
The outer surfaces 23a, 23a of 23, 23 are formed in parallel to each other as shown in FIGS. 3 and 4.

Further, as shown in FIG. 5, at one end (the right end in the illustrated example) in the length direction of each of the ridges 23, 23, a downward slope is formed from the end of the ridge 23 to the lower edge 23b of the ridge. The guide surfaces 23c are provided respectively. In addition, the upper surface 23d of each protrusion 23 is formed as an inclined surface having a downward slope.

A flange portion 21a is provided on the outer periphery of the lower end of the fitting cylinder 21, and a convex portion 21b for positioning is provided on the outer periphery of the flange portion 21a.
The fitting cylinder 21 is fitted in the 2a to prevent the fitting cylinder 21 from rotating.

Next, the locking portion of the feeding container body 1 will be described.
This is because the fitting hole 30 is formed at the bottom of the guide cylinder 13, and the inner wall surface 30a of the fitting hole 30 is under the projections 23 when the feeding container body 1 is rotated in the circumferential direction. The protrusions 31 that engage with the edges 23b are provided by the number (4) of the protrusions 23. The distance between these opposing projections 31 is set to be slightly larger than the outer diameter of the fitting cylinder 31, as shown in FIG. 3, etc. Also, one end 31a of each projection 31 has a bottom plate portion of the guide cylinder 13. The one end 31a is configured to come into contact with the end portion of the projection 23 when the feeding container body 1 is mounted to restrict the rotation of the feeding container body 1.

Further, the inner wall surface 30a of the fitting hole 30 has such a dimension as to come into surface contact with the outer surface 23a of the protrusion 23 when the protrusion 23 and the protrusion 31 are in an engaged state, as shown in FIG. The fitting holes 30 are formed in a substantially octagonal shape. Regarding the height positional relationship between each protrusion 31 and each protrusion 23, as shown in FIG.
The upper edge of the protrusion 31 is set to be located higher than the lower edge 23b of the protrusion 23 by the tightening margin T, and the peripheral wall forming the fitting hole 30 functions as a bullet plate portion. The projections 31 are formed to have a wall thickness that is effective, and the lower edges 31b of the projections 31 are formed to have a downward slope.

In the stick-shaped cosmetic container having such a configuration, the fitting cylinder 21 in the makeup cylinder 2 is cylindrical, and the projections 23 of the fitting cylinder 21 and the projections 31 of the fitting hole 30 as a whole. Since both have no inclination, the guide cylinder 13 of the feeding container body 1 is simply inserted into the makeup cylinder body 2 without any alignment of the feeding container body 1 with respect to the fitting cylinder 21. By inserting the fitting cylinder 21 in the makeup cylinder 2 into the fitting hole 30 at the bottom of the guide cylinder 13 and slightly rotating the feeding container body 1 in one direction (right direction), the middle of the rotation. First, the guide surface of the ridge 23
A so-called extremely short screw mechanism is configured by engaging the projections 31 with 23c, respectively, and with the rotation thereof, the feeding container body 1 is forced downward by an amount corresponding to the tightening margin T by the action of the guide surface 23c. A so-called vertical axial load is generated by pulling it down, and the inner wall surface of the fitting hole 30 is partially formed in the protrusion 23.
When the feeding container body 1 is rotated against this, the peripheral wall of the fitting hole 30 has an elastic effect on the outer wall of the fitting hole 30. When the feeding container body 1 is elastically deformed toward the outside to allow the feeding container body 1 to rotate, and further rotated, the peripheral wall returns to its original state as shown in FIG. 23a, respectively. At this time, the protrusion 31 of the fitting hole 30 engages with the lower edge 23b of the protrusion 23, and further, one end 31a of the protrusion 31 abuts on one end of the protrusion 23, and the feeding container body 1 rotates further. Is regulated not to.

Then, as a result, the feeding container body 1 is locked and fixed in the makeup cylinder 2. Further, in this state (the inner wall surface 30a of the fitting hole 30 is in contact with the outer surface 23a of the protrusion 23, respectively), the peripheral wall of the guide cylinder 13 forming the fitting hole 30 is extended to such an extent that it is elastically deformed. As long as the container body 1 is not rotated, the delivery container body 1 does not loosen carelessly. Also,
It is needless to say that the rotational force when the delivery container body 1 and the makeup tube body 2 are combined is set to be larger than the rotational force at the time of delivery. The stick-shaped cosmetic can be used without any problem.

According to this embodiment, the upper surface 23d of each protrusion 23 is formed as a downward slope, and the lower edge 31b of the protrusion 31 of the fitting hole 30 is also formed as a downward slope. Therefore, for example, when the feeding container body 1 is mounted and the protrusion 31 is located immediately above the ridge 23, the fitting hole 30 is formed by pressing the feeding container body 1 on the vehicle. The protrusion 31 rides over the protrusion 23 by the elastic deformation of the peripheral wall of the guide cylinder 13 to the outside, and these are engaged with each other, so that the feeding container body 1 can be mounted.

When the feeding container body 1 is removed, if the feeding container body 1 is rotated and raised in the opposite direction, the protrusion 23 and the projection 31 are disengaged, and the feeding cylinder body 2 can be removed. The feeding container body 1 can be easily replaced as a cartridge.

FIG. 6 shows a second embodiment of the present invention, in which a biasing means 35 for biasing the feeding container body 1 upward is provided inside a fitting cylinder 21 provided in the decorative cylinder portion 2. Then, the ridge 23 and the protrusion 31
The feeding container body 1 is pushed upward by the urging means 35 at the same time as the engagement with is disengaged and the removal thereof is simplified. As the urging means 35, as shown in FIG. 6, it is composed of a push-up member 36 that comes into contact with the bottom of the guide cylinder 13 and a coil spring 37 that urges the push-up member 36 upward. Etc., but other structures may be used.

FIG. 7 shows a third embodiment of the present invention. Instead of the protrusion 23 and the protrusion 31 of the horizontal structure shown in FIG. 1 and the like, the protrusion 23 extends in the circumferential direction of the fitting cylinder 21. Accordingly, the protrusion 31 is formed so as to descend, and the protrusion 31 is screwed to the protrusion 23.

With such a structure, a screw mechanism is configured when the ridge 23 and the protrusion 31 are engaged with each other, and it is possible to tighten the delivery container body 1 in the decorative cylinder body 2 and loosen and rotate them. Is preferable because it can prevent

FIG. 8 and FIG. 9 show a fourth embodiment of the present invention, in which one end of the projection 31 is simply horizontal structure without bending and the projection 31 is horizontally symmetrically formed. It is configured to engage with the ridge 23.

With such a structure, the feeding container body 1 can be rotated to the left or right to release the engagement between the protrusion 23 and the protrusion 31. As shown in FIG. 9, with respect to the line segment XY along the radial direction of the fitting cylinder 21, one of the left and right lengths l ₁ and l ₂ from this line segment XY is set from the other. If the structure is also formed to be large, it is possible to increase the turning resistance on the increased side, and for example, the same effect as that of the embodiment shown in FIG. 1 and the like can be obtained.

[Advantages of the Invention] As described above, according to the present invention, the delivery container body in which the tray moves up and down by the relative rotation of the spiral tube and the guide tube and the outer shape of the guide tube of the delivery container body are integrally formed. A decorative tubular body to be fitted is provided, and a cylindrical fitting tube is provided at a bottom portion of the decorative tubular body along an axial direction of the tubular body, and the fitting tubular body is fitted at a position where the outer peripheral surface of the fitting tube faces each other. At least a pair of projections extending in the circumferential direction of the coupling cylinder are provided, and the projections of the pair are formed on the outer surfaces of the projections in parallel to each other, while the fitting cylinder is fitted to the bottom of the guide cylinder. A fitting hole that fits into the fitting cylinder is formed, and the inner wall surface of the fitting hole is engaged with the lower edge of the protrusion when the feeding container body is rotated in the circumferential direction, Is provided with a protrusion that restricts the movement of the fitting hole in the axial direction. Since the setting is made so as to make surface contact with the outer surface of the projection when in the engaged state, when the delivery container body is attached to the decorative cylinder, simply place the delivery container body on either the left or right side. The operation of the cosmetic container can be carried out very easily by simply rotating or pushing it down in a certain direction, and the cosmetic container can be controlled by restricting the axial movement of the container. It can be reliably prevented from falling off from the body, and when the delivery container body is removed, it can be easily removed by slightly rotating it and pulling it out. Therefore, the feeding container body can be replaced with one touch, and the usability can be improved.

Further, since the locking structure of the feeding container body can be realized with a simple structure, the cost can be reduced.

Here, if one end of the protrusion is formed to be bent and the one end is brought into contact with the end portion of the protrusion to restrict the rotation of the feeding container body, the inner wall surface of the fitting hole and the protrusion are formed. The rotation of the feeding container body is restricted during the surface contact with the outer surface of the above, and there is an effect that it is possible to prevent overshoot at the time of rotation.

On the other hand, if the ridge is formed so as to descend as it extends in the circumferential direction of the fitting cylinder, the ridge and the protrusion can be screwed together, and a strong axial load is applied to the feeding container body. Therefore, it is possible to improve the stability of the mounting.
