The opening 2J is slightly elastically deformed in the width direction and is widened, so that the center chuck 4 can be incorporated into the centering guide hole 2G from the radial direction.
[0019]
As shown in FIGS. 1 and 2, the front end of the cover container 3 is a portion that is fitted to the outer periphery of the intermediate portion of the tapered container 2 and is mounted so as to be relatively rotatable. An annular groove 3A that can be engaged with an annular protrusion 2D formed on the outer peripheral surface of the intermediate portion of the container 2 is formed. A knurl 3B is formed on the outer peripheral surface of the base end portion of the cover container 3 as a non-slip during a rotation operation. A female screw portion 3 </ b> C is formed on the inner peripheral surface of the portion of the cover container 3 except for the front end portion, the screw mechanism being a part of the advance / retreat driving mechanism of the lead chuck 4 and the lead screw 4. . In addition, a flange 3D that functions as a stopper when the cosmetic supply container 1 is incorporated as a part of the cosmetic application container is formed on the outer periphery of the cover container 3.
[0020]
Here, the lead chuck 4 is made of a chuck portion 4A that grips the base end portion of the stick-shaped cosmetic material A, and an engaging portion 4B that is moved forward and backward by engaging with a forward / backward drive mechanism configured in the container body. It has a structure connected to each other via a small-diameter connecting portion 4C. The core chuck 4 is integrally formed of a synthetic resin.
[0021]
As shown in an enlarged view in FIG. 5, the chuck portion 4A of the core chuck 4 has a short elliptical columnar base against which the elliptical base end face of the rod-shaped cosmetic material A shown in FIG. 4A1 and a pair of gripping pieces 4A2 projecting from two locations in the short axis direction of the end face of the base 4A1 and gripping the peripheral surface of the base end of the rod-shaped cosmetic A are integrally formed. The chuck portion 4A is slidably inserted into and engaged with the centering guide hole 2G of the tapered container 2 shown in FIG.

The screwing projection 4B3 is securely screwed to the female screw portion 3C without play by the pair of elastic support pieces 4B4 having elasticity capable of elastic deformation in the radial direction of the female screw portion 3C.
[0024]
Further, when an overload is applied to the screwing projection 4B3 at the end of the female screw 3C, the elastic support piece 4B4 on which the screwing projection 4B3 protrudes is elastically deformed radially inward of the female screw 3C, thereby forming a screw. The screwing state between the mating projection 4B3 and the female screw portion 3C is temporarily released to function as a torque limiter.
[0025]
The cosmetic dispensing container 1 according to one embodiment including the tapered container 2, the cover container 3, and the core chuck 4 is assembled in the following procedure. First, as shown in FIG. 6, the core chuck 4 is inserted into the centering guide hole 2G from the opening 2J of the tapered container 2 and incorporated therein. At this time, the opening portion 2J is sequentially expanded in the width direction from the chuck portion 4A side to the engaging portion 4B while bending the connecting portion 4C of the core chuck 4 due to its flexibility, and the center chuck 4 is aligned with the centering guide hole 2G. Insert
[0026]
By employing such an assembling procedure, the center chuck 4 can be easily incorporated into the centering guide hole 2G of the tapered container 2. Also, the center chuck 4 longer than the length of the opening 2J can be easily incorporated into the centering guide hole 2G.
[0027]
Next, the base end portion of the tapered container 2 is inserted into the distal end portion of the cover container 3 from the hole 2F side, and the two are relatively moved closer in the axial direction, so that the outer peripheral surface of the intermediate portion of the tapered container 2 is formed. The tip of the cover container 3 is fitted. At this time, the distal end of the cover container 3 is guided by the tapered slope 2C of the tapered container 2 and smoothly fits on the outer peripheral surface of the intermediate portion of the tapered container 2.
[0028]
Subsequently, a pair of screwing projections 4B3 projecting from the engaging portion 4B of the core chuck 4 inserted into the tapered container 2 is tapered so that the pair of screwing projections 4B3 is screwed into the female screw portion 3C on the inner periphery of the cover container 3. The container 2 and the cover container 3 are relatively rotated. Then, by further rotating the two relative to each other, the lead chuck 4 is moved backward to the base end side of the cover container 3 by a screw mechanism in which the pair of screwing projections 4B3 and the female screw portion 3C are screwed.
[0029]
In this state, the tapered container 2 and the cover container 3 are further moved closer in the axial direction. Then, while the distal end portion of the cover container 3 is slightly elastically deformed in the radial direction, the annular groove 3A on the inner peripheral surface engages with the annular protrusion 2D on the outer peripheral surface of the intermediate portion of the tapered container 2, and the distal end surface of the cover container 3 The cover container 3 is attached to the tapered container 2 so as to be rotatable relative to the stepped portion 2B of the tapered container 2.
[0030]
Therefore, the tapered container 2 and the cover container 3 are relatively rotated to move the lead chuck 4 slightly (about 2 to 3 mm) forward from the initial position shown in FIG. Then, in this state, the base end of the stick-shaped cosmetic A is inserted from the outlet 2A of the tapered container 2 to a position between the pair of gripping pieces 4A2 of the chuck 4A to be gripped. Thereafter, the tapered container 2 and the cover container 3 are relatively rotated so that the core chuck 4 moves back to the initial position, and the stick-shaped cosmetic A is drawn into and stored in the tapered container 2.
[0031]
In the cosmetic dispensing container 1 of the embodiment assembled as described above, the opening 2J formed on the peripheral surface of the tapered container 2 is covered with the cover container 3, so that a good appearance can be obtained.
[0032]
In this cosmetic dispensing container 1, the engaging piece 4B2 of the engaging portion 4B of the core chuck 4 is inserted into the locking groove 2G2 of the centering guide hole 2G in the tapered container 2 and rotation thereof is restricted. When the container 2 and the cover container 3 are rotated relative to each other, the lead chuck 4 rotates relative to the cover container 3. Since a pair of screwing projections 4B3 projecting from the engaging portion 4B of the lead chuck 4 is screwed to the female screw portion 3C of the cover container 3, the relative rotation between the taper container 2 and the cover container 3 is caused. The lead chuck 4 is driven forward and backward along the axis of the tapered container 2.
[0033]
At this time, the slide 4B1 of the engaging portion 4B is guided by the guide hole 2G1 of the centering guide hole 2G, so that the lead chuck 4 is driven forward and backward in a smooth state without tangling or catching. As a result, the rod-shaped cosmetic material A gripped by the pair of gripping pieces 4A2 of the chuck portion 4A of the core chuck 4 smoothly protrudes and retracts from the outlet 2A at the distal end of the tapered container 2.
[0034]
When the tapered container 2 and the cover container 3 are rotated relative to each other with the lead chuck 4 reaching its forward end or the retreat end, a pair of elastic support pieces 4B4 of the engaging portion 4B of the lead chuck 4 project. Overload is applied to the screwing projection 4B3, the elastic support piece 4B4 is elastically deformed radially inward of the female screw 3C of the cover container 3 and functions as a torque limiter. 3C damage is prevented beforehand.
[0035]
Here, in the cosmetic dispensing container 1 of one embodiment, when an external impact is applied due to dropping or the like, or when an excessive bending load is applied by being crushed in a handbag or the like, the core chuck 4 is It is bent by the flexible small-diameter connecting portion 4C to absorb a bending load. For this reason, an excessive bending load does not act on the rod-shaped cosmetic material A held by the chuck portion 4A of the core chuck 4, and breakage of the rod-shaped cosmetic material A is prevented.
