For example, flocking is performed on the surface of an elastic body of a porous material such as foamed urethane or NBR through which the cosmetic A can pass. The applicator 10a has an outer peripheral side that is pulled downward so as to wrap the elastic portion 10b from the outside and is hooked on the protruding portion 4p of the middle cylinder 4 so that the elastic portion 10b is placed between the upper portion of the middle cylinder 4 and the applicator 10a. It is attached to the middle cylinder 4 in a sandwiched state.

  As shown in FIGS. 1 and 3, the cap 11 is a dome-shaped lid that curves so as to protrude upward, and is screwed onto the inner peripheral surface of the cap 11 with the male screw 3f of the upper cylindrical portion 3e of the joint 3. A possible female screw 11a is provided, and the female screw 11a and the male screw 3f are screwed together to be attached to the joint 3.

  Next, the operation of the powder cosmetic container 100 having such a configuration will be described. First, as shown in FIGS. 1 and 3, from the state where the female screw 11 a of the cap 11 is tightened to the male screw 3 f of the joint 3 to the screwing limit and the cap 11 is attached to the joint 3. explain. In this state, as described above, one of the rotation stoppers 4j of the middle cylinder 4 hits one of the rotation stopper ribs 2f of the base cap 2 (the other of the rotation stoppers 4j of the middle cylinder is the rotation stopper rib of the base cap 2). 3f, the closed portion 4g, which is the arc surface of the middle cylinder 4, closes the radial through hole 2k of the outer cylindrical portion 2h (the middle cylinder 4). The closed portion 4g is located at a position facing the through hole 2k.

  Here, since the outer cylindrical part 2h is an elastic body, it has a high repulsive force or restoring force. For this reason, a desired surface pressure that spreads almost uniformly outward in the radial direction over the entire circumference of the cylindrical portion 2h forming the closed section is ensured with respect to the closed portion 4g of the middle cylinder 4, and as a result, airtight Ensuring is fully achieved. Therefore, when the powder cosmetic containing a volatile component is accommodated, volatilization of the volatile component is prevented.

  When using from this state, the user turns the cap 11 in the direction of loosening (screwing release direction: one direction) to open the cap 11. Then, since the female screw 11a of the cap 11 is fastened to the male screw 3f of the joint 3 to the screwing limit, the cap 11 and the joint 3 are integrated with each other, and the joint 3 and the middle cylinder 4 are joined together with the cap 11. The closed portion 4g of the middle cylinder 4 that is integrally rotated in the screwing release direction with respect to the base 1 and the base cap 2 and rotated around the axis line and directly opposed to the through hole 2k of the cylindrical portion 2h outside the base cap 2 is the circumferential direction. At the same time, the guide path (concave portion) 4f of the middle cylinder 4 moves along the circumferential direction so as to face the through hole 2k.

  When the rotation stop 90j rotates and one of the rotation stoppers 4j of the middle cylinder 4 hits the other of the rotation stopper ribs 2f of the base cap 2 (the other of the rotation stoppers 4j of the middle cylinder 4 When it hits one side), the rotation of the joint 3 and the middle cylinder 4 together with the cap 11 in the unscrewing direction is temporarily stopped, and in this state, as shown in FIGS. 4 and 17, the guide path 4f of the middle cylinder 4 However, the powder cosmetics A that have passed through the through-hole 2i of the inner cylindrical portion 2g and the through-hole 2k of the outer cylindrical portion 2h are passed through the application body 10 (the guide path 4f of the middle cylinder 4 has the through-hole 2k). (Positively facing).

  In this state, when the user further rotates the cap 11 in the screwing release direction, the rotation of the middle cylinder 4 and the joint 3 in the same direction is prevented by the rotation stopping rib 2f of the base cap 2, so that the cap 11 rotates in the screw release direction, the screw 11a of the cap 11 with respect to the male screw 3f of the joint 3 is released, and the cap 11 is removed, resulting in the state shown in FIG. That is, removal of the cap 11 and airtight release for delivering the powder cosmetic A are performed.

  In use, when the application body 10 is lightly struck and pressed against the user's skin, for example, the powder cosmetic A in the base 1 is placed in the cylindrical portion 2a of the base cap 2 as indicated by an arrow. , Through the through holes 2i and 2k and the guide path 4f of the middle cylinder 4, and then flow out through the application body 10 to be applied.

  When the use is finished, the user turns the cap 11 in the direction in which the cap 11 is tightened (screwing direction: the other direction opposite to the one direction) to close the cap 11. Then, when the female screw 11a of the cap 11 is screwed into the male screw 3f of the joint 3 and is tightened to the screwing limit, the cap 11 and the joint 3 are united together with the cap 11 and the joint 3 and the middle. The cylinder 4 rotates integrally with the base 1 and the base cap 2 in the screwing direction and rotates around the axis, and the guide path 4f facing the through hole 2k of the cylindrical portion 2h outside the base cap 2 extends along the circumferential direction. At the same time, the closing portion 4g of the middle cylinder 4 moves along the circumferential direction so as to face the through hole 2k.

  When the rotation stopper 4j of the middle cylinder 4 is rotated 90 degrees and one of the rotation stopper ribs 2f of the base cap 2 abuts against one of the rotation stopper ribs 2f of the base cap 2 (the other of the rotation stopper 4j of the middle cylinder 4 When it hits the other side), the rotation of the joint 3 and the middle cylinder 4 together with the cap 11 is stopped, and in this state, as shown in FIG. 3 and FIG. It is located at the closed position that closes the through hole 2k of the outer cylindrical portion 2h and returns to the initial position. That is, the cap 11 is attached and airtightness is sufficiently achieved.

  Thus, in the present embodiment, airtightness securing and airtight release for delivering the powder cosmetic A can be easily performed in conjunction with a series of operations for opening and closing the cap 11, and the outer cylinder. Since the part 2h has a repulsive force or a restoring force, a desired surface pressure is ensured for the middle cylinder 4 that spreads almost uniformly radially outward over the entire circumference of the cylindrical part 2h forming the closed section. As a result, airtightness can be sufficiently secured.

  In the present embodiment, the cylindrical portion 2a has an inner cylindrical portion 2g and an outer cylindrical portion 2h, the outer cylindrical portion 2h is an elastic body (packing), and the through holes 2i and 2k are formed on the inner side. While being provided so as to penetrate the cylindrical portion 2g and the outer cylindrical portion 2h in the radial direction, the elastic body has a higher repulsive force or restoring force, so that airtightness can be more sufficiently ensured.

  Since the airtightness can be ensured in conjunction with the series of operations for opening and closing the cap 11 as described above, the airtightness and cap by closing the radial through hole 2k only by closing the cap 11. 11 can be secured.

  Even if the airtight rib 2s of the outer cylindrical portion 2h is not provided, the airtight rib 2s may not be provided as long as the airtightness can be secured between the closed portion (arc surface) 4g of the middle cylinder 4.

  As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the cylindrical portion 2a is preferably disposed on the inner side. A cylindrical portion 2g and an outer cylindrical portion 2h are provided, and the outer cylindrical portion 2h is made of an elastic body such as polyethylene or elastomer. However, the cylindrical portion 2a is not divided into an inner portion and an outer portion, and only an elastic body such as polyethylene or elastomer is used. A desired surface pressure may be secured to the middle cylinder 4 by the outer peripheral surface of the cylindrical portion of the elastic body. Similarly, the cylindrical portion 2a is not divided into the inside and the outside, for example, PP or the like. It is also possible to use only those having the repulsive force or restoring force, and to secure a desired surface pressure against the middle cylinder 4 by the outer peripheral surface of the cylindrical portion. In any case, since the cylindrical portion 2a has a repulsive force or a restoring force, sufficient airtightness can be ensured. In particular, in the case of only an elastic body, since a higher repulsive force or restoring force is provided, the airtightness is ensured. Can be performed more fully. Further, when the materials of the inner cylindrical portion 2g and the outer cylindrical portion 2f are different, two-color molding may be used.

  Moreover, in the said embodiment, although the two through-holes 2i and 2k are made into 2 opposing as especially preferable, 1 piece or 3 or more may be sufficient.

  In the above-described embodiment, the powder cosmetic A is particularly preferably a powder cosmetic containing a volatile component. For example, the powder cosmetic A containing a component unstable to moisture or deliquescence is present. The present invention can also be applied to powder cosmetics that require airtightness, such as powder cosmetics containing components.

  Further, in the above-described embodiment, as a particularly preferable position, the position where the guide path 4f of the middle cylinder 4 directly faces the through hole 2k is set as an open position where the powder cosmetic A passing through the through hole 2k is allowed to pass to the application body 10. Although (the position where the through hole 2k is fully opened is the open position), the guide path 4f is not opposed to the through hole 2k but is shifted in the circumferential direction to open the position where the through hole 2k is, for example, half open or small open. It may be included in the position. Thus, after the cap 11 is rotated, for example, the through hole 2k is in a half-open or small-open state, and only the cap 11 is further rotated to remove the cap 11, thereby releasing the hermeticity for delivering the powder cosmetic A. This can be performed in conjunction with a series of operations for opening the cap 11. Then, the through hole 2k may be used as it is, for example, in a half-open or small-open state.

  Furthermore, as another embodiment of the present invention, by adjusting the degree of screwing of the female screw 11a of the cap 11 with respect to the male screw 3f of the joint 3, the cap 11, the joint 3 and the middle cylinder 4 are screwed simultaneously. Instead of turning in the mating release direction, first, only the cap 11 is turned in the screwing release direction to remove the cap 11, and then the joint 3 is turned in the screwing release direction so that the guide path 4 f of the middle cylinder 4 is aligned with the through hole 2 k. On the other hand, it can also be set as the powder cosmetic container 100 which moves along the circumferential direction. In this case, since the opening degree of the through-hole 2k can be adjusted to, for example, full open or half open, the powder cosmetic A can be delivered according to the user's preference.
