The present invention will be described below based on preferred embodiments with reference to the drawings.

  The casing 1 of the stick-shaped cosmetic container of the present invention has a cylindrical shape with the front end and the rear end open. At the front end of the housing 1, a circular flange 1 a that protrudes inward from the inner peripheral surface is formed. A fitting portion 1b is formed at the rear end of the housing 1. The fitting portion 1b is a circular convex portion projecting inward from the inner peripheral surface thereof. Further, on the inner peripheral surface of the housing 1, vertical ribs 1 c that protrude inward from the inner peripheral surface and extend from the vicinity of the front end of the fitting portion 1 b toward the open portion of the front end of the housing 1 are provided in the circumferential direction. Two are formed at equal intervals.

  A feeding body 3 is provided at the rear end of the casing 1. The feeding body 3 includes a rod-shaped support portion 3a in which a male screw portion 3d is formed, a cylindrical tube portion 3b in which a circular convex portion (fitting portion 3e) protruding outward from the outer peripheral surface is formed, and a tubular shape The operation portion 3c is formed. The outer diameter of the operation portion 3 c is substantially the same as the outer diameter of the housing 1. The cylindrical portion 3b having an outer diameter smaller than that of the operating portion 3c is formed at the front end of the operating portion 3c. A circular step portion 3f protruding inward from the operation portion 3c is formed between the operation portion 3c and the cylinder portion 3b. And the support part 3a whose outer diameter is smaller than the said cylinder part 3b is formed in the front end of the said cylinder part 3b.

  A front end surface of the step portion 3 f of the feeding body 3 is locked to the rear end surface of the housing 1. Further, the fitting portion 1 b of the housing 1 and the fitting portion 3 e formed on the cylindrical portion 3 b of the feeding body 3 are fitted. Therefore, the feeding body 3 does not come out of the housing 1, and the feeding body 3 can rotate with respect to the housing 1 around the central axis of the feeding body 3.

  An intermediate dish 4 is provided between the outer peripheral surface of the support portion 3 a of the feeding body 3 and the inner peripheral surface of the housing 1. The inner tray 4 includes a circular large-diameter portion 4a formed with an outer diameter slightly smaller than the inner diameter of the housing 1, and a circular small-diameter portion 4b formed with an outer diameter smaller than the outer diameter of the large-diameter portion 4a. It is formed with. The small diameter portion 4b is formed at the front end of the large diameter portion 4a. Further, a through hole is formed at the center of the inner tray 4. On the inner peripheral surface of the through hole, a female screw portion 4c that is screwed with the male screw portion 3d formed on the outer peripheral surface of the support portion 3a of the feeding body 3 is formed. In addition, on the outer peripheral surface of the large diameter portion 4a, two vertical grooves 4d that are recessed inward from the outer peripheral surface and extend in the axial direction are formed at equal intervals in the circumferential direction. And the said inner tray 4 is arrange | positioned inside the said housing | casing 1 so that the two vertical ribs 1c of the said housing | casing 1 may fit, facing the two vertical grooves 4d of the said inner tray 4. FIG. . Further, a circumferential groove 4e, which is a circumferential concave groove extending rearward from the front end surface, is formed on the front end surface of the large diameter portion 4a. Further, the outer peripheral surface of the inner tray 4 protrudes outward from the outer peripheral surface of the intermediate tray 4 at a position slightly forward from the rear end surface of the intermediate tray 4 and is slightly smaller than the inner diameter of the guide member 5 described later. The outer flange 4g is formed

  The operation part 3c of the feeding body 3 is rotated, and the support part 3a is rotated. The rotation of the support portion 3a is transmitted to the female screw portion 4c of the intermediate plate 4 screwed. However, rotation of the inner tray 4 is restricted because the vertical groove 4d of the inner tray 4 and the vertical rib 1c of the housing 1 are fitted. Therefore, when the operation unit 3c is rotated, the inner plate 4 does not rotate and moves forward in the housing 1, and when the operation unit 3c is rotated reversely, the inner plate 4 moves backward. That is, the inner plate 4 can be moved back and forth with respect to the housing 1 by the rotation operation of the operation portion 3c.

  A cylindrical guide member 5 is provided between the outer peripheral surface of the support portion 3 a of the feeding body 3 and the inner peripheral surface of the housing 1 and in front of the inner tray 4. At the rear end of the guide member 5, a circular outer flange 5 a that protrudes outward from the outer peripheral surface of the guide member 5 and is slightly smaller than the inner diameter of the housing 1 is formed. On the outer peripheral surface of the outer flange portion 5a, two longitudinal grooves 5b that are recessed inward from the outer peripheral surface and extend in the axial direction are formed at equal intervals in the circumferential direction. The guide member 5 is arranged inside the housing 1 so as to face the two vertical grooves 5b of the guide member 5 and to fit the two vertical ribs 1c of the housing 1. . Therefore, the guide member 5 does not rotate in the axial direction with respect to the housing 1. Further, a circular inner flange portion 5 c that protrudes inward from the inner peripheral surface of the guide member 5 is formed at the rear end of the guide member 5.

A coil spring 6 (elastic member) is provided between the rear end surface of the guide member 5 and the bottom surface 4f of the circumferential groove 4e of the inner plate 4. On the inner periphery of the front end of the coil spring 6 and the inner periphery of the rear end, a circular protrusion 5e that protrudes from the rear end surface of the guide member 5 and has a height approximately equal to the wire diameter of the coil spring 6, and the dish 4 The circular protrusions 4h that protrude forward from the bottom surface 4f formed at a height about the wire diameter of the coil spring 6 are respectively fitted. For this reason, the lateral deflection of the coil spring 6 moving in the circumferential direction is prevented. The guide member 5 is always urged forward by the coil spring 6. Further, the elastic force of the coil spring 6 (elastic member) has an urging force that urges the guide member 5 forward, and when the guide member 5 comes into contact with the lips of the user, the coil spring 6 (elastic member) contracts with an appropriate contraction force. Anything to do. In the present invention, the coil spring 6 is used, but a rubber member may be used as long as it has elasticity and can be biased, and is not particularly limited.
The guide member 5 is biased forward by the biasing force of the coil spring 6. However, the front end surface of the inner flange portion 5 c of the guide member 5 is in contact with the rear end surface of the outer flange portion 4 g of the inner tray 4. Therefore, the guide member 5 is restricted from moving forward from the housing 1 and is not detached from the housing 1.

  It is necessary for the guide member 5 to prevent lateral deflection that moves in the circumferential direction with respect to the casing 1 and the small diameter portion 4b of the inner tray 4. In the present invention, the flange 1 a of the housing 1 prevents the front side of the guide member 5 from swinging with respect to the outer peripheral surface of the guide member 5. In addition, the inner peripheral surface of the casing 1 and the outer peripheral surface of the small-diameter portion 4b of the inner plate 4 are prevented from sideways with respect to the outer flange portion 5a and the inner flange portion 5c of the guide member, respectively. Yes.

The rear end surface of the rod-shaped lipstick body 2 (rod-shaped cosmetic body) is in contact with the front end surface of the support portion 3a of the inner plate 4 inside the guide member 5. Further, the front end portion of the small diameter portion 4b of the inner tray 4 is inserted into the lipstick body 2, and the lipstick body 2 is prevented from falling off due to the resistance of the insertion portion. Here, the rotation operation of the feeding body 3 will be described again. When the rotation operation of the feeding body 3 is performed, the inner tray 4 moves back and forth with respect to the housing 1. By the back-and-forth movement, the lipstick body 2 that is in contact with the inner plate 4 and is prevented from falling off by being inserted into the small-diameter portion 4b is fixed to the inner plate 4 via the coil spring 6. The guide member 5 also moves back and forth together.
The guide member 5 is biased forward by the coil spring 6. Therefore, when a force is applied rearward from the front end surface of the guide member 5, the guide member repels the urging force of the coil spring 6 and moves rearward. However, when the force applied rearward from the front end surface of the guide member 5 is lost, the guide member 5 is moved forward by the biasing force of the coil spring 6 and returns to the original biased state. .
The lipstick body 2 (bar-shaped cosmetic body) may be a bar-shaped cosmetic body such as a lip cream or a concealer like the lipstick body 2 and is not limited to lipstick.
Further, the casing 1, the lipstick body 2, the feeding body 3, the inner plate 4, and the guide member 5 are formed in a circular shape such as a cylindrical shape or a cylindrical shape, but are not limited thereto, and an elliptical shape, a polygonal shape, etc. Appropriate selection is possible according to usability and appearance. The inner shape portion and the outer diameter portion may be irregularly shaped and can be selected as appropriate.

Next, the actual operation will be described.
When a user (not shown) uses the stick-shaped cosmetic container of the present invention, first, the feeding body 3 is rotated, and the lipstick body 2 and the guide member 5 are moved back and forth. And the protrusion amount from the front-end surface of the said housing | casing 1 is adjusted to the quantity which a user can apply | coat easily. In addition, when the stick-shaped cosmetic container is not used, the front end surface of the guide member 5 and the front end surface of the lipstick body 2 are set at the same position. Further, the rotation of the inner tray 4 and the guide member 5 is restricted with respect to the casing 1 during the forward and backward movement. Therefore, the inclined portion 5f provided at the front end of the guide member 5 and the inclined portion 2a provided at the front end of the lipstick body 2 are always in the same direction.

In the state described above, the user presses the lipstick body 2 against the lips (application surface) to perform the application work of the lipstick body 2 on the lips. Here, when the stick-shaped cosmetic container is not used, the front end surface of the lipstick body 2 and the front end surface of the guide member 5 are simultaneously in contact with the lips. Therefore, the lipstick body 2 can be applied to the lips. Further, when the stick-shaped cosmetic container is used to some extent and the lipstick body 2 is reduced, the front end surface of the lipstick body 2 is slightly lowered from the front end surface of the guide member 5. At that time, the front end surface of the guide member 5 comes into contact with the lips before the front end surface of the lipstick body 2. In that case, the guide member 5 is repelled by the urging force of the coil spring 6 and moves backward, so that the front end surface of the lipstick body 2 and the front end surface of the guide member 5 simultaneously contact the lips. It will be in the state. Therefore, the lipstick body 2 can be applied to the lips.
As described above, during application, the lipstick main body 2 is in a state where the entire side surface portion of the portion protruding from the front end surface of the housing 1 is protected by the guide member 5. And in the state which pressed the said lipstick main body 2 on the lips, it will be used by sliding on the lip surface. At that time, even if a load is applied in the direction in which the lipstick body 2 is folded, the guide member 5 supports the lipstick body 2 so that the lipstick body 2 does not fall down. I can do it. Further, when the application is finished and the guide member 5 is separated from the lips, the guide member 5 moves forward by the urging force of the coil spring 6 and returns to the original urging state.

The inner surface shape of the guide member 5 will be described.
If the inner surface shape of the guide member 5 is a through hole whose inner diameter does not change from the front end surface to the rear end surface, the outer peripheral surface of the lipstick body 2 is protected by the guide member 5 described above, and the lipstick body 2 is folded. You can get the effect of not.
Here, in the present invention (FIG. 1), the inner shape of the guide member 5 is formed as a gently tapered shape whose inner diameter increases from the front end surface of the cylindrical portion toward the rear end surface (taper portion). 5d). The gap formed by the inner diameter of the rear part of the guide member 5 and the outer peripheral surface of the lipstick body 2 is smaller than the gap formed by the inner diameter of the front part of the guide member 5 and the outer peripheral surface of the lipstick body 2. . Therefore, even when the lipstick body 2 is pressed against the lips and slid on the lip surface and a load is applied in the direction in which the lipstick body 2 is broken, the displacement amount of the rear portion from the front portion of the lipstick body 2 is large. Get smaller. Therefore, compared with the case where the inner diameter portion of the guide member 5 is a through hole where the inner diameter does not change, there is an effect that the lipstick main body 2 is more difficult to bend when it has a gentle taper. Further, a gap is formed on the outer peripheral surface of the lipstick main body 2 and the inner peripheral surface of the guide member 5 as the inner diameter of the guide member 5 is increased. Therefore, when the front end surface of the lipstick main body 2 or the wrinkle portion is deformed during application of the lipstick main body 2, fragments and the like generated due to the shape loss easily fall into the gap. Therefore, it is difficult for the fragments generated due to the deformation of the shape to protrude outside the guide member 5. Accordingly, it is possible to prevent the finger from touching the lipstick fragments and getting dirty, or applying the fragments to unintended portions.

  Next, an embodiment of the guide member 5 will be described with reference to longitudinal sectional views of the guide member 3 shown in FIGS.

A first embodiment will be described with reference to FIGS.
In FIG. 2, a curved surface portion 8 is provided on the front end surface of the guide member 5. As described above, the front end surface of the guide member 5 directly contacts the user's lips. Therefore, if a corner is formed on the front end surface of the guide member 5, the lip may be injured at the corner. Therefore, a curved surface portion is provided on the front end surface of the guide member 5 to prevent injury.

A second embodiment will be described with reference to FIG.
In FIG. 3, rubber 8 is attached to the front end portion of the guide member 5. In this embodiment, the rubber 8 is fixed to the front end surface of the guide member 5 by adhesion, but may be fixed by a method such as fitting or press-fitting. The rubber 8 is not limited to rubber as long as the material has a softness that does not damage the lips. By providing the rubber 8, injuries can be prevented in the same manner as the curved surface portion 7 in FIG. The front end surface of the rubber 8 is a corner, but in this embodiment as well, the front end of the rubber 8 is provided with a curved surface at the portion that contacts the lips as in the first embodiment. May be.

A third embodiment will be described with reference to FIG.
In FIG. 4, an enlarged diameter portion 9 is provided in which the inner diameter and the outer diameter of the guide member 5 are increased from a position slightly behind the front end face of the guide member 5 toward the front end face. Compared with a shape in which a gentle taper is provided only on the inner diameter of the guide member 5, the thickness of the expanded portion is not reduced by the amount of expansion of the outer diameter together, and sufficient strength can be maintained. And the clearance gap with the said lipstick main body 2 by having expanded the internal diameter of the said guide member 5 can be ensured more largely. Therefore, the fragments due to the loss of shape of the lipstick body 2 are more likely to enter the gap. Therefore, it is possible to more reliably prevent the lipstick body 2 from being inadvertently touched with a finger and contaminated, or to be applied to an unintended portion.
Further, the front end surface of the enlarged diameter portion 9 is a corner portion. Also in this embodiment, a curved surface portion is provided on the upper end surface of the guide member at the portion contacting the lips as in the first embodiment. It may be provided.
