Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stick-shaped cosmetic container in which stick-shaped cosmetics such as lipstick, lip balm, and tic are used out of the container.
[0002]
[Prior art]
Recently, as a feeding container for stick-shaped cosmetics such as lipstick, a simplified assembly process has been proposed in Japanese Patent Laid-Open No. 8-275822. As shown in FIG. 17, the stick-shaped cosmetic material supply container includes a holding cylinder 31 that holds the lower end portion of the stick-shaped cosmetic material 30, a guide cylinder 32 that houses the holding cylinder 31 slidably up and down, and the guide cylinder. A sleeve 33 (see FIG. 18) in which a shallow and fine knurled spiral groove 33a is engraved on the inner peripheral surface, and an outer cylinder 34 for fixing the lower end of the guide cylinder 32. A cap 35 that is attached to the cylinder 34, and when projecting on the outer peripheral surface of the holding cylinder 31, the coupling portion 31a is inserted into a guide groove 32a formed in the guide cylinder 32 and protrudes laterally. Thus, the sleeve 33 is engaged with the knurled spiral groove 33a. In FIG. 17, reference numeral 36 denotes a fitting portion provided at the upper end portion of the outer cylinder 34, and the cap 35 is detachably fitted thereto. Reference numeral 37 denotes a protrusion provided at the lower end of the sleeve 33, which is rotatably engaged with an annular groove 38 provided on the lower outer peripheral surface of the guide tube 32. When this stick-shaped cosmetic material supply container is used, the sleeve 33 and the outer cylinder 34 are rotated relative to each other, whereby the guide cylinder 32 and the sleeve 33 fixed to the outer cylinder 34 are rotated relative to each other. The holding cylinder 31 is moved up and down with the rotation. Thereby, the bar-shaped cosmetic 30 can be fed out or lowered from the upper end opening of the guide tube 32. In this case, at the time of assembling, the sleeve 33 is fitted on the guide cylinder 32 in which the holding cylinder 31 is housed without aligning the joint portion 31a of the holding cylinder 31 and the knurled spiral groove 33a of the sleeve 33. The fitting portion 31a and the knurled spiral groove 33a can be joined together, and assembly is easy.
[0003]
[Problems to be solved by the invention]
However, in this case, since the guide tube 32 and the sleeve 33 are made of a synthetic resin material, there is a vertical backlash between the annular groove 38 provided in the guide tube 32 and the protrusion 37 provided in the sleeve 33. Sticking is likely to occur, and the relative rotation between the guide tube 32 and the sleeve 33 is not smoothly performed. Therefore, it is conceivable to install an O-ring instead of providing the protrusion 37 on the sleeve 33. In this case, since the O-ring attached to the sleeve 33 abuts on the annular groove 38 of the guide cylinder 32 in an elastic manner, there is no backlash in the vertical direction between the annular groove 38 of the guide cylinder 32 and the O-ring. Further, the relative rotation between the guide tube 32 and the sleeve 33 is smoothly performed. However, in this case, it is difficult to automatically perform the operation of attaching the O-ring to the sleeve 33 by the machine, and there is a problem that it is necessary to rely on manual operations.
[0004]
The present invention has been made in view of such circumstances, and can provide a bar-shaped cosmetic container that can eliminate backlash in the vertical direction between the inner cylinder and the outer cylinder and that can be automatically assembled. For that purpose.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a stick-shaped cosmetic container according to the present invention comprises a feeding cylinder for holding a stick-shaped cosmetic material, an inner cylinder in which the feeding cylinder is accommodated so as to be freely fed, and a relative rotation with respect to the inner cylinder. An outer cylinder that is externally fitted, and a rotation operation unit that is integrally attached to the inner cylinder and that advances and retracts the feeding cylinder by its own rotation. The upper end portion of itself is connected to the inner cylinder with a predetermined gap, and a hole is formed in the upper end connection portion of the rotation operation portion. An annular rubber elastic body is provided which is inserted from the lower end opening of the operation portion and is inserted and fixed in a non-rotating manner between the lower portion of the inner cylinder and the rotation operation portion, and corresponds to the hole of the rotation operation portion. A configuration is adopted in which a projecting portion that is slidably contacted with the lower end portion of the outer cylinder 3 through the hole is provided in the upper end surface portion of the annular rubber elastic body.
[0006]

Therefore, when the inner cylinder rotates relative to the outer cylinder, the lower end of the outer cylinder rotates while sliding in a resilient manner on the protrusion of the annular rubber elastic body. Is called. Moreover, since the annular rubber elastic body can be inserted from the lower end opening of the rotation operation portion and fitted and fixed in a non-rotating manner between the lower portion of the inner cylinder and the rotation operation portion, automatic assembly is possible. It becomes possible.
[0007]
Further, in the present invention, a notch extending from the lower end surface is formed in the peripheral wall portion of the feeding cylinder, and the inner peripheral surface of the inner cylinder is formed on the outer peripheral surface of the peripheral wall portion of the feeding cylinder in the vicinity of the notch. When projecting a projecting part that is in sliding contact with the outer cylinder, even if there is a small gap between the outer peripheral surface of the inner cylinder and the inner peripheral surface of the outer cylinder, Slidably contact the inner peripheral surface of the inner surface, and no looseness occurs between the two peripheral surfaces, so that it rotates smoothly. Further, in the present invention, a protrusion is provided on the outer peripheral surface of the upper end of the inner cylinder in the circumferential direction so as to form an annular protrusion, and the upper end of the outer cylinder is rotatable on the inner peripheral surface of the annular protrusion. When the groove that engages with the ring is provided in the circumferential direction and formed into an annular groove, rattling in the vertical direction can be eliminated by the engagement between the annular protrusion of the inner cylinder and the annular groove of the outer cylinder. Furthermore, when the inner cylinder and the outer cylinder are relatively rotated, both the cylinders rotate in the circumferential direction, and this rotation is performed smoothly.

[0015]
As shown in FIGS. 13 and 14, the cap 5 is formed in a cylindrical cylindrical shape, and can be externally fitted with a small gap between the cap 5 and the sleeve 3. An inner cylindrical portion 24 is suspended from the lower surface of the ceiling wall 5a of the cap 5. The inner cylindrical portion 24 is formed with a tapered concave portion 24a extending from the lower end surface at a position where the inner cylindrical portion 24 faces each other, and the lower peripheral wall of the inner cylindrical portion 24 is formed as an elastic member by both concave portions 24a. . Such an inner cylindrical portion 24 has an outer diameter that is slightly larger than the inner diameter of the upper end portion of the inner cylinder 2 of the flange 7. When the inner cylindrical portion 24 is fitted into the inner cylinder 2, the upper end of the inner cylinder 2 is formed. The diameter of the portion, that is, the annular ridge 17 is slightly increased.
[0016]
Such a bar-shaped cosmetic container can be assembled as follows. That is, first, the sliding ring 6 is disposed below the lower end opening of the rotation operation unit 4, and each sliding contact protrusion 25 of this sliding ring 6 is positioned in each engagement hole 2 c of the inner cylinder 2 ( In other words, the sliding ring 6 is pushed into the rotation operation unit 4 side (see FIG. 15). As a result, the sliding contact projections 25 of the sliding ring 6 are inserted into the insertion holes 19a of the rotation operation unit 4 and protrude slightly upward, and the sliding rings 6 of the sliding ring 6 are inserted into the engagement holes 2c of the inner cylinder 2. The engagement protrusion 26 is engaged in a retaining shape. Next, the inner tray 1 is arranged above the upper end opening of the inner cylinder 2, both guide projections 11 of the inner dish 1 are positioned in both vertical holes 2 a of the inner cylinder 2, and in this state, the inner dish 1 is Push in 2 side. As a result, one of the guide protrusions 11 engages with the vertical hole 2 a of the inner cylinder 2 through the gap 16 of the inner cylinder 2 while expanding the upper end of the inner cylinder 2. Next, the sleeve 3 is inserted from above the inner cylinder 2. Thereby, the spiral groove 10 of the guide protrusion 11 and the spiral groove 21 of the sleeve 3 are joined together (see FIG. 16). After that, the cap 5 is crowned from above the sleeve 3 in an outer fitting manner. As a result, the inner cylindrical portion 24 of the cap 5 is fitted into the upper end portion of the inner cylinder 2 in a retaining manner, and the annular protrusion 17 of the inner cylinder 2 expands in diameter and is pressed into the annular groove 20 of the sleeve 3. Abut.
[0017]
In the state where the cap-shaped cosmetic container assembled in this manner is in a state where the cap 5 is removed (see FIG. 16), the collar 7 (that is, the inner cylinder 2 and the rotation operation unit 4) rotates relative to the sleeve 3. When the both cylinders 3 and 7 are rotated relative to each other, the inner cylinder 2 is rotated relative to the sleeve 3 along with the relative rotation. 1 moves up and down in the vertical hole 2a. Thereby, the inner tray 1 moves up and down in the inner cylinder 2. When not in use, the inner plate 1 is lowered and rotated in the circumferential direction at the lower end position to engage with the horizontal hole 2b, so that the inner plate 1 does not rise carelessly. Put on the crown. In this crowned state (see FIG. 1), the annular projection 17 of the inner cylinder 2 is expanded in diameter by the inner cylindrical portion 23 of the cap 5 and pressed against the annular groove 20 of the sleeve 3. For this reason, the inner cylinder 2 and the sleeve 3 do not rotate relative to each other. On the other hand, in use, the cap 5 is removed to expose the sleeve 3, and the collar 7 is rotated relative to the sleeve 3. At this time, the flange portion 23 of the sleeve 3 is in sliding contact with the sliding contact protrusion 25 of the sliding ring 6 in a resilient manner and rotates smoothly. Then, due to the relative rotation, the inner tray 1 moves up with the basket 7 and rises. It is rotated in the circumferential direction at the ascending end position and engaged with the horizontal hole 2b so that the inner tray 1 does not inadvertently descend. As a result, the bar-shaped cosmetic 8 protrudes from the upper end opening of the sleeve 3 and is ready for use.
[0018]
Thus, in the above embodiment, the inner cylinder 2 and the sleeve 3 do not rotate relative to each other when the cap 5 is attached. Moreover, since the sliding contact portion 15 of the inner tray 1 is in sliding contact with the inner peripheral surface of the inner cylinder 2 during rotation, no lateral rattling occurs between the inner tray 1 and the inner cylinder 2. , Both smoothly rotate relative to each other. Further, an annular protrusion 17 is provided in the circumferential direction on the outer peripheral surface of the upper end portion of the peripheral wall portion of the inner cylinder 2, and an annular groove 20 is formed in the peripheral direction on the inner peripheral surface of the upper end portion of the sleeve 3. Since the inner cylinder 2 and the sleeve 3 rotate relative to each other in the circumferential direction because they are freely engaged, this rotation is performed smoothly and the upper end of the sleeve 3 (the upper wall of the annular groove 20). Acts to prevent the middle dish 1 from coming off. Further, since the flange portion 23 of the sleeve 3 abuts on the sliding contact projection 25 of the sliding ring 6 in a resilient manner, there is no backlash in the vertical direction, and the inner cylinder 2 and the sleeve 3 smoothly rotate relative to each other during use. Move. Furthermore, since the elastic piece 14 is formed in the peripheral wall part of the lower part of the inner plate 1 at a position directly below both guide protrusions 11, even when the inner plate 1 is slightly inclined and pushed into the inner cylinder 2 side during assembly, The elastic piece 14 is bent well and the inner dish 1 and the inner cylinder 2 are not damaged. In addition, the stick-shaped cosmetic container is composed of the inner plate 1, the sleeve 3, the basket 7, and the cap 5, and has a small number of parts.
[0019]
