A spiral groove 1 a is formed on the inner peripheral surface of the outer cylindrical body 1, while a guide groove 2 f with a recess 2 g is formed on the outer peripheral surface of the inner dish body 2, and a gap between the outer cylindrical body 1 and the inner dish body 2 is formed. An outer protrusion 4b is formed at the lower end of the movable cylinder 4 inserted into X to engage with the spiral groove 1a to move the movable cylinder 4 up and down. The inner protrusion 4a guided to the guide groove 2f in the state of entering and exiting is formed so that the moving operation of the movable cylinder 4 is strong and weak.

Description

  The present invention belongs to the technical field of stick-shaped cosmetic containers such as lipsticks.

In general, stick-shaped cosmetics such as lipsticks support the lower end portion of the cylinder main body at the upper end portion of the outer cylinder body so as to be relatively rotatable, and in the spiral groove formed on the inner peripheral surface of the outer cylinder body. Screw the projections formed on the outer peripheral surface of the inner plate body with cosmetics supported on the surface, and the inner plate body moves upward in conjunction with the rotation of the outer cylinder body with respect to the tube main body. It protrudes freely from the upper end of the main body (for example, Patent Document 1). However, in this case, since the cosmetic protrudes due to the upward movement of the inner plate body with respect to the cylinder main body, the user tends to prolong the protrusion of the cosmetic inevitably, and the cosmetic tends to soften. Not only does the cosmetics break easily, but there is a problem that the cosmetics are crushed by the lid when the lid is closed without fully charging the cosmetics.
On the other hand, the cosmetic is projected by being moved downward without rotating the cylinder body with respect to the inner plate body, and thus the cosmetic is not crushed even if the cosmetic is covered in the projected state. What was made is known (for example, patent document 2).

  Next, a first embodiment of the present invention will be described with reference to FIGS. In the drawings, reference numeral 1 denotes an outer cylindrical body having a bottomed cylindrical shape. The outer cylindrical body 1 has a spiral groove (screw groove) 1a formed on an inner peripheral surface and a locking hole 1c formed on a bottom surface 1b. The intermediate dish body 2 is supported in a state where the intermediate dish body 2 can be rotated relative to the outer cylinder body 1 by forcibly engaging a locking groove 2a formed at the lower end portion of the intermediate dish body 2 with a force fit. The outer diameter of the intermediate dish 2 is smaller than the inner diameter of the outer cylinder 1 (the outer diameter of the spiral groove), whereby the outer peripheral surface of the intermediate dish 2 and the inner peripheral surface of the outer cylinder 1 are separated. A gap X is formed in. Further, on the inner cylinder surface side of the middle dish body 2, a dish bottom portion 2b is formed on the upper half side, the dish bottom portion 2b is used as a bottom surface, and a dish portion Y formed in the upper cylinder of the dish bottom portion 2b. The lower part of the cosmetic 3 having a bar shape is inserted and incorporated. In the present embodiment, the outer diameter A of the outer peripheral portion 2d below the lower surface 2c is the outer diameter of the upper outer peripheral portion 2e with respect to the position corresponding to the lower surface 2c of the dish bottom portion 2b. The diameter B and the small diameter (A <B) are equal, but may be equal (A = B) and stopped in the groove. Can be set. On the outer peripheral surface of the lower outer peripheral portion 2d of the intermediate dish body 2, a guide groove 2f that is long in the vertical direction is formed, and further, a recess 2g is formed in the guide groove 2f at a predetermined interval.

  On the other hand, 4 is a cylindrical movable cylinder (inner lid) having both ends opened, and the lower end of the movable cylinder 4 is composed of an outer peripheral surface of the intermediate dish 2 and an inner peripheral surface of the outer cylinder 1. Is inserted into the gap X formed between them from the upper end side. An inner protrusion (locking protrusion) 4a that fits and locks into the guide groove 2f is formed on the inner peripheral surface of the lower end of the movable cylinder 4 that is inserted into the gap X, and is screwed into the spiral groove 1a. An outer protrusion (engagement protrusion) 4b that is engaged (engaged) is formed on the outer peripheral surface, but the inner protrusion 4a is immersed in the recess 2g formed in the guide groove 2f between the outer protrusion 4b and the spiral groove 1a. (In this embodiment, the depth of the recess 2g and the immersion amount of the inner protrusion 4a are the same. However, the present invention is not limited to this, and the present invention can be applied regardless of whether the immersion amount is larger or smaller.) A gap Z corresponding to C is secured. The movable cylinder 4 is rotated relative to the outer cylinder 1 in a state along the spiral groove 1a, so that the movable cylinder 4 is formed between the outer cylinder 1 and the inner dish body 2. It moves up and down (moves forward and backward) in the gap X formed between them, and at this time, the movable cylinder 4 is moved relative to the cosmetic 3 incorporated so as to be rotatable relative to the outer cylinder 1. The inner protrusion 4a is guided in the guide groove 2f so as to move up and down, thereby allowing the cosmetic 3 to be exposed from the upper side. Incidentally, the upper and lower ends of at least one of the recess 2g or the inner protrusion 4a are tapered (chamfered), so that the inner protrusion 4a can smoothly enter and exit the recess 2g. Incidentally, the inner protrusion 4a and the outer protrusion 4b can be formed not at the same position but at a shifted position.

  In this case, when the movable cylindrical body 4 is moved downward relative to the outer cylindrical body 1 with the inner protrusion 4a immersed in the uppermost recess 2g. The inner protrusion 4a is forced out of the recess 2g in a state of resistance (over the mountain) and comes into sliding contact with the bottom surface of the guide groove 2f, so that the lower end portion of the movable cylinder 4 becomes the recess 2f. However, this deformation is absorbed by the gap Z formed between the outer protrusion 4b and the spiral groove 1a, so that the movable cylinder Smooth relative rotation along the spiral groove 1a of the body 4 is not hindered, and a change in strength is generated in the vertical movement due to the elastic deformation, so that torque fluctuation can be sensed sensuously. Further, the sliding contact based on the vertical movement of the inner protrusion 4a and the recess 2f is given a tension in advance so as to obtain a stable torque. Incidentally, the elastic deformation of the lower end portion of the movable cylindrical body 4 can be ensured by the elastic characteristics of the resin material itself when the movable cylindrical body 4 is formed of a resin material having expansion and contraction elasticity. For those that do not, it can be ensured by cutting in the vertical direction.

  When the movable cylinder 4 is further moved downward with the inner protrusion 4a protruding from the uppermost recess 2g, the inner protrusion 4a is fitted into the lower recess 2g in a state of elastic return, and then The movable cylinder 4 moves down to the lowest position while coming out of this position and slidingly contacting the guide groove 2f again and fitting into the next lower recess 2g. In addition, when the movable cylinder 4 is rotated upward relative to the outer cylinder 1 in the opposite direction, the movable cylinder 4 is moved up to the uppermost position while repeating in the opposite direction to the case of moving downward. Become. As described above, the inner protrusion 4a is repeatedly inserted into and removed from the recess 2g and the lower outer peripheral surface portion 2d is slid, whereby a change in strength is generated in the vertical movement operation of the movable cylinder 4. In other words, the movement of the movable cylinder 4 can be recognized sensuously, and when inserted into the recess 2g, the inner projection 4a hits the groove bottom of the recess 2g and a click sound is generated to make an auditory recognition. You can also.

  When the movable cylinder 4 is moved upward and the inner protrusion 4a is inserted into the uppermost recess 2g and further moved upward, in this embodiment, the upper outer diameter portion of the intermediate dish 2 is used. Since the outer diameter B of 2e is larger than the outer diameter A of the lower outer peripheral portion 2d, the outer protrusion 4b tends to bulge beyond the contact with the groove bottom of the spiral groove 1a. 4b is restricted from coming out of the spiral groove 1a, and further upward movement is restricted. Incidentally, when the diameter is the same, it can be stopped by groove formation as described above.

In the embodiment of the present invention configured as described above, the inner dish body 2 is supported so as to be relatively rotatable with respect to the outer cylinder body 1 and does not move up and down, and the cosmetic 3 is fitted outside. The movable cylinder 4 moves up and down with respect to the outer cylinder 1 by using the movable cylinder 4 as the movable cylinder 4. At this time, the movable cylinder 4 rotates relative to the inner dish 2. Therefore, the cosmetic 3 will not be crushed even if it is capped with the cosmetic 3 protruding from the movable cylinder 4. Moreover, the spiral groove 1a for moving the movable cylinder 4 in and out is formed on the inner peripheral surface of the outer cylinder 1 facing the inner dish body 2 and does not face the cosmetic 3. As a result, the cosmetic 3 will not be damaged.
In addition, a guide groove 2f as a guide mechanism for moving the movable cylinder 4 up and down without rotating relative to the middle dish 2 is formed in the middle dish 2 covered by the outer cylinder 1, Since the inner protrusion 4a protruding from the lower end portion inserted into the gap X of the movable cylinder 4 is inserted into the guide groove 2f and locked and guided up and down without relative rotation, the movable cylinder is different from the conventional one. There is no possibility that the cosmetics can be seen through the guide holes formed in the body 4, and as a result, it is possible to avoid the problem that dust or the like adheres to the cosmetics 3.

When the movable cylinder 4 is rotated relative to the outer cylinder 1 to move in and out, the inner protrusion 4a formed on the movable cylinder 4 moves in a state of entering and exiting the recess 2g formed on the guide groove 2f. However, it is possible to control the amount of protrusion of the cosmetic 3 from the movable cylinder 4 due to the resistance at the time of going in and out, and to prevent the cosmetic 3 from protruding too much. become.
Further, by setting the concave portion 2g at the position where the movable cylinder 4 protrudes most, an operation of protruding the movable cylinder 4 too much can be avoided. Moreover, in the present embodiment, when the movable cylinder 4 is further protruded, the inner protrusion 4a has a large diameter so that the inner protrusion 4a does not exceed the recess 2g, and the inner protrusion 4a may exceed the inner protrusion 4a. It is convenient that there is no consideration. Incidentally, when the diameter is the same as described above, it can be stopped by forming a groove.

In addition, in this case, as shown in FIG. 6A, in a state where the inner protrusion 4a is immersed in the recess 2g, the outer protrusion 4b and the spiral groove 1a are separated by an amount corresponding to the immersion amount C (or more). Since the gap Z is secured between them, as shown in FIG. 6B, when the inner protrusion 4a comes out of the recess 2g and comes into sliding contact with the guide groove 2f, the outer protrusion 4b presses against the spiral groove 1a and slides. Since the dynamic resistance is not increased and the smooth movement of the movable cylinder 4 is not hindered, and the sliding resistance is repeatedly generated, the rotational torque fluctuates and this can be sensibly known.
In addition, when the inner protrusion 4a is immersed in the recess 2g, the inner protrusion 4a hits the recess 2g, so that a click sound is generated and the operation can be realized.

In addition, this invention is not limited to the said embodiment, Like the 2nd-4th embodiment shown to FIGS. 7-9, it is a linear form long on the internal peripheral surface of the movable cylinder 4 in the up-down direction. The concave groove 4c can be formed. In these embodiments, the concave grooves 4c are formed at equal angles (180 degrees, 90 degrees, and 45 degrees) in the circumferential direction of two, four, and eight, respectively. Thus, when filling the movable cylindrical part 4 formed with the concave groove 4c with the soft cosmetic 3 in the form of a paste, the cosmetic 3 enters the concave groove 4c and becomes a large diameter. As a result, The cosmetic 3 has a convex rib 3a that is long in the vertical direction on the outer peripheral surface. The amount of the cosmetic 3 increases accordingly, and is reinforced and hard to break. In other words, these embodiments are able to reinforce the soft bottom-filled cosmetic material in the form of convex stripes whose surface is long in the vertical direction, and can reduce the occurrence of defects that break in the middle. Become. Of course, it can be used for either the direct filling method for filling from the tip side or the bottom filling method for filling from the bottom side. It can be implemented by aligning and inserting the rib 3a and the groove 4c.
Incidentally, in the case of forming a convex stripe shape on the outer peripheral surface of the cosmetic 3, the number, size, and position thereof are not particularly limited, and as shown in FIG. The inner peripheral surface may be a protrusion 4d, and thereby a concave rib 3b that is long in the vertical direction may be formed on the outer peripheral surface of the cosmetic 3. Further, a convex strip or a concave groove may be formed on the outer peripheral surface of the cosmetic 3. May be formed so as to be repeated in the circumferential direction.

Furthermore, a fifth embodiment shown in FIG. 10 is used as a mountain-climbing mechanism that gives a strength or a click sound to the rotating operation on the intermediate dish 2 and the movable cylinder 4 with respect to the outer cylinder 1. You can also. In this structure, a mountain crossing mechanism is formed at a support portion of the locking hole 6a and the locking groove 7a at the bottom portion that supports the outer cylinder body 6 and the inner tray body 7 so as to be relatively rotatable. As the mountain crossing mechanism, as shown in FIG. 10A, a convex rib 6b is formed on the inner peripheral surface of the outer cylindrical body locking hole 6a, and the convex rib 6b is formed on the inner tray body 7 with respect to the outer cylindrical body 6. By the relative rotation, the groove piece 7b of the locking groove 7a is made to go over the mountain, and in FIG. 5B, the length of the convex rib 6c is made longer. Can also implement the present invention. Furthermore, as a mountain crossing mechanism, a convex rib may be formed on the locking groove side, or the present invention is implemented even if a convex rib is formed in both the outer cylindrical body locking hole and the intermediate dish locking groove. can do.
Furthermore, an unevenness is formed in a spiral groove for moving the movable cylinder up and down relative to the outer cylinder, and the rotation operation is made stronger and weaker by making it go over the unevenness, and a click sound is generated. Can be configured.

  INDUSTRIAL APPLICABILITY The present invention is useful for a container for stick-shaped cosmetics such as lipstick, and a cylindrical body that externally fits the stick-shaped cosmetic is moved up and down in a state of rotating relative to the outer cylindrical body as a movable cylindrical body. As a result, it is possible to prevent the locking projection protruding from the movable cylindrical body from being seen from the outside while preventing the bar-shaped cosmetic from being crushed even if the cap is capped in a protruding state. Furthermore, even if the stick-shaped cosmetic is soft, it is reinforced by entering into the concave groove formed on the inner surface of the movable cylinder, and it is prevented from being broken in the middle can do.
