Thus, the one member and the other member can be combined so as to be rotatable with one touch. Further, as long as the rear end part is not pushed forward against the urging force of the urging means, such rotation can be prevented.
(2) Next, when such rotation is required, the rear end part is pushed forward against the urging force of the urging means to move forward, thereby causing the protrusion to escape from the recess. Such rotation can be performed with one touch by urging the means. At the same time, braking can be applied to the rotation by the braking means.

Further, the shaft unit may have the following configurations (1) to (6).
(1) One member having a first portion having a first through hole and a second portion having a second through hole;
The other member having a third portion with a third through hole,
In a state where the third part is placed between the first part and the second part, and the first through hole, the third through hole, and the second through hole are in communication with each other,
A shaft unit that is inserted into these through-holes that are communicated with each other so that the one member and the other member are rotatably assembled.

A revolving sliding surface is formed on which the protrusion of the rear end part that has come out of the recess by the pushing forward operation of the rear end part against this biasing is abutted from the front end side of the main cylinder part.

According to such a configuration,
(1) First, from the state in which the third part of the other member is placed between the first part and the second part of one member, the front end part is inserted into the second through hole, and the intermediate part is inserted into the third through hole. In addition, the rear end parts are inserted into the first through holes, and the shaft unit is inserted into these through holes, so that the one member and the other member can be combined with each other in a single touch. it can. Further, as long as the rear end part is not pushed forward against the urging force of the urging means, such rotation can be prevented.
(2) Next, when such rotation is required, the rear end part is pushed forward and operated against the urging force of the urging means, and the protrusion of the rear end part is pulled out from the recess of the main cylinder portion. Thus, the rotation can be performed with one touch by the biasing of the biasing means. At the same time, braking can be applied to the rotation by the braking means.
(3) When the other member rotated to the rotation end position is rotated to the position before the rotation start, the intermediate part is rotated toward the non-rotation position and rotated to the non-rotation position. When moved, the projection of the rear end part enters the recess of the main cylinder portion again by the biasing means, and the state where the intermediate part is in this unrotated position is maintained. That is, the state of the other member returned to the position before the start of rotation is maintained again.

  An inclined surface that is inclined in such a direction that the protrusion is extracted from the recess while rotating the intermediate part in the direction of the rotation bias by the biasing means by pushing the forward movement of the rear end part. It may be left as it is.

  According to such a configuration, the intermediate part, that is, the other member can be rotated in advance in the process in which the protrusion comes out of the recess associated with pushing the rear end part and moving forward. When the rotational resistance at the start is the highest, the other member can be reliably rotated by supplementing the biasing force. When the intermediate part is returned to the non-rotation position by the operation of returning the other member to the position before starting the rotation, the protrusion can be easily drawn into the recess by the urging of the urging means at the final stage.

  An elastic protrusion may be formed at the rear end of the front end part housed in the sub-cylinder portion of the intermediate part, and a free stop action may be applied to the intermediate part by pressure contact of the elastic protrusion.

  In this case, the intermediate part can be temporarily fixed by the pressure contact of the elastic protrusion at any rotational position of the intermediate part. That is, when the rotation operation of the other member is stopped, the other member can be held at that position.

An elastic protrusion is formed at the rear end of the front end part that is housed in the sub-cylinder portion of the intermediate part, and
The sub-cylinder part of the intermediate part has a wide diameter part and a narrow diameter part,
An elastic protrusion is abutted against the step surface between the wide diameter portion and the narrow diameter portion before reaching the rotation end position due to the rotation of the intermediate part by the rotation bias of the biasing means. Is stopped,
The rotation of the intermediate part from the stop position to the end may be performed by pressing the elastic protrusion against the inner wall of the narrow diameter portion while elastically deforming the elastic protrusion.

  In this case, the automatic rotation of the intermediate part permitted by the pushing forward operation of the rear end part by the biasing means can be temporarily stopped before reaching the rotation end position. Between the stop position and the rotation end position, the intermediate part can be temporarily fixed by pressing the elastic protrusion against the inner wall of the narrow diameter portion of the sub-cylinder portion at any rotation position of the intermediate part. . In other words, the rotation of the other member rotated by the rotation of the intermediate part from the fixed position to the front is allowed in a state where the other member is held at that position when the rotation operation is stopped. Can be made.

  Locked at the rear end of the rear end part so that it can move from the unlocked position where the side part does not protrude sideways from the side surface of the rear end part to the locked position where the side part protrudes sideways. The body may be assembled.

  In such a case, by sliding the lock body to the lock position while the intermediate part is in the non-rotating position, the side of the lock body is abutted even if a pushing force is applied to the lock body. Thus, the rear end part can be prevented from moving in the pushing direction, and the intermediate part, that is, the other member can be prevented from rotating unexpectedly.

Can be assembled in a rotatable manner.

  According to such a configuration, it is possible to stably maintain the state in which the one container structure and the other container structure overlap each other. In addition, by pushing the rear end part of the shaft unit with the hand on the side holding the cosmetic container and performing a forward operation, the other container component can be automatically rotated while applying braking in the opening direction from the overlapped state. Can do. Furthermore, when the shaft unit has the elastic protrusion, the automatic rotation of the other container structure can be stopped halfway, and the free stop action is applied to the other container structure after the stop position. The other container structure can be rotated while applying the above. Further, when the shaft unit has a lock body, the rear end of the shaft unit is unexpectedly moved by moving the lock body of the shaft unit to the lock position in a state where the one container structure and the other container structure overlap each other. It is possible to prevent the parts from being pushed in and the other container structure to open.

Having an inner lid body having a fourth part with a fourth through-hole through which an intermediate part of the shaft unit is inserted;
As the other container structure is opened by the rotation of the intermediate part, the outer surface of the third part of the other container structure abuts the edge of the inner lid body on the rotating assembly side at a predetermined rotation position. There is a case where an abutting portion for linking is formed so that the inner lid body is opened together from this position.

  In this case, the inner lid body can be rotated in the same direction from the middle of the rotation in accordance with the rotation of the other container constituting body by the urging of the urging means.

  Further, in order to solve the above-mentioned problems, in the present invention, the operation method of the rotating body is set such that the other member assembled so as to be rotatable with respect to one member is rotated from the start of rotation of the other member. In the meantime, after the automatic rotation to the predetermined rotation position while applying the brake, the other member is manually rotated while applying the free stop action after the predetermined rotation position. It was supposed to be.

  In this case, the rotating body can be automatically rotated slowly until the middle of rotation, and then manually rotated in a state where the posture can be maintained at an arbitrary rotation position. .

Further, in the illustrated example, the second through-hole 411 has a stepped surface 412 between the two through-holes having a small diameter at the side communicating with the third through-hole 501 and an enlarged tip of the small-diameter portion. Along with the insertion of the front end portion 200 from the small diameter side into the front end portion 200 of the front end part 2, the front end portion 200 is partly elastically deformed and then elastically restored at the fully inserted position. A hooking protrusion 201 that is hooked on the step surface 412 is formed, so that the front end portion 200 of the front end part 2 once passed through the second through hole 411 does not come out of the second through hole 411. It is. Such hooking protrusions 201 are formed on both narrow surfaces of the front end portion 200 of the front end part 2, and the formation positions of the hooking protrusions 201 are defined by the through holes 202 extending between the two wide surfaces between the forming positions. In this way, it is easy to be elastically deformed. As will be described later, the front end part 2, the intermediate part 3 and the rear end part 1 are integrated, and the second part 410 having the second through hole 411 and the rear end part 1 are inserted and assembled. Since the first part 400 having the hole 401 is provided on the same one member 4 ′, the one member 4 ′ and the other member 5 ′ are obtained by the fixing and engagement of the front end part 2 to the second through hole 411. Is stably integrated by the shaft unit J in a rotatable state.

On the other hand, the intermediate part 3 is

Is configured to have a cylindrical shape with both ends open. In the illustrated example, the connection projection 303 formed on the outer surface of the rear end portion 302 of the sub cylinder portion 300 is connected to the connection window hole 325 formed in the front end portion 323 of the main cylinder portion 320. When the rear end portion 302 of the sub cylinder portion 300 is inserted into the main cylinder portion 320 from the front end portion 323 side of 320, the intermediate portion 3 is formed by engaging with the rear end portion 302. Further, the rear end portion 203 of the front end part 2 is configured to have a substantially cylindrical shape, and the front end part 2 is inserted into the sub cylinder portion 300 of the intermediate part 3 from the front end portion side of the sub cylinder portion 300. It is rarely combined with this intermediate part 3. In the illustrated example, the opening of the sub-cylinder portion 300 of the intermediate part 3 is closed by a retaining ring 304 that is fastened to the opening while the rear end portion 203 of the front end part 2 is inserted. Yes. A seal ring 305 is provided at the tip of the retaining ring 304 so as to be in pressure contact with the outer surface of the rear end portion 203 of the front end part 2 and the inner surface of the sub cylinder portion 300. Prior to the seal ring 305, a viscous fluid (not shown) such as silicone oil is enclosed in the sub-cylinder portion 300. Due to the viscous fluid thus sealed, braking is applied to the rotation of the intermediate part 3 with the rear end portion 203 of the front end part 2 as the rotation axis. That is, in the illustrated example, the front end part 2 and the sub-cylinder portion 300 including such a viscous fluid function as the braking means 301.

Further, in this embodiment, an elastic protrusion 204 is formed on the rear end portion 203 of the front end part 2 housed in the sub cylinder portion 300 of the intermediate part 3,
The sub-cylinder portion 300 of the intermediate part 3 has a wide diameter portion 306 and a narrow diameter portion 307,
The elastic protrusion 204 abuts against the stepped surface 308 between the wide-diameter portion 306 and the narrow-diameter portion 307 before reaching the rotation end position by the rotation of the intermediate part 3 by the rotation bias of the biasing means 321. Once this rotation is stopped,
The rotation of the intermediate part 3 from the stop position to the end is allowed by pressing the elastic projection 204 against the inner wall of the narrow-diameter portion 307 while elastically deforming it.

An elastic member 205 having a plate shape with one plate edge protruding slightly from the peripheral surface of the rear end portion 203 is provided, and the elastic protrusion 204 is constituted by one plate edge of the elastic member 205. I am letting. As the elastic member 205, rubber or plastic having rubber-like elasticity can be used. In addition, in the illustrated example, substantially half of the arc constituting the cross-sectional shape in the direction perpendicular to the axis of the sub-cylinder part 300 ahead of the seal ring 305 in the sub-cylinder part 300 is the front end part 2. An arc following the cross-sectional shape of the rear end portion 203, and the remaining arc constituting the cross-sectional shape is a virtual circle whose diameter is the diameter of the front end part 2 at the position where the elastic protrusion 204 of the front end part 2 is formed. It is designed to be a circular arc. As a result, the wide-diameter portion 306, the narrow-diameter portion 307, and the step surface 308 are formed in the sub-cylinder portion 300. In the illustrated example, the elastic protrusion 204 of the rear end portion 203 of the front end part 2 is in contact with the start-end side step surface 309 between the wide diameter portion 306 and the narrow diameter portion 307 when the intermediate part 3 is not rotated. ing. (FIG. 12) When a state in which the rotation of the intermediate part 3 is allowed by the urging force of the urging means 321 is created by pushing forward operation of the rear end part 1 to be described later, the elastic protrusions are formed on the step surface 308 of the sub cylinder portion 300. The intermediate part 3, that is, the other member 5 ′ is rotated by this biasing to the stop position at which 204 is abutted. In the example shown in the figure, the other member 5 'is rotated by this biasing by approximately 90 degrees. (FIGS. 2 and 3) When an external force is applied so as to further rotate the other member 5 ′ first from this stop position, the sub-cylinder portion 300 rotates while the elastic protrusion 204 is gradually elastically deformed by the step surface 308. As a result, the elastic protrusion 204 enters the narrow diameter portion 307 in a deformed state. In the illustrated example, in this state, the other member 5 'can be further rotated by approximately 80 degrees. (Figs. 4 and 5)

  Thereby, in this embodiment, the automatic rotation by the urging means 321 of the intermediate part 3 permitted by the pushing forward operation of the rear end part 1 reaches the rotation end position. The inner wall of the narrow-diameter portion 307 of the sub-cylinder portion 300 of the elastic protrusion 204 can be temporarily stopped before and from the stop position to the rotation end position at any rotation position of the intermediate part 3. The intermediate part 3 can be temporarily fixed by pressure contact. That is, in this embodiment, when the rotation of the other member 5 ′ rotated by the rotation of the intermediate part 3 is stopped from the fixed position, the rotation operation is stopped at that position. It can be allowed (so-called free stop) in a state where the other member 5 ′ is fastened.

  In the illustrated example, a compression coil spring 322 is used as the biasing means 321. In the illustrated example, a protruding portion 310 divided into two by a sandwiching groove 311 at the spring end is formed on the outer surface of the closed other end of the sub-cylinder portion 300, and the front end of the rear end part 1 is formed. Similarly, a protrusion 102 that is divided into two by a sandwiching groove 103 at the spring end is formed in the portion 100. In the example shown in the figure, one end of the spring 322 is inserted and locked in the sandwiching groove 311 of the protrusion 310 of the sub cylinder portion 300, and the other end of the spring 322 is connected to the rear end part 1. A spring 322 is built in the main cylinder portion 320 so as to be inserted and locked in the sandwiching groove 103 of the protrusion 102.

Further, in this embodiment, the protrusion 105 formed on the front end portion 100 of the rear end part 1 is placed inside the main cylinder portion 320 in the unrotated position by the biasing means 321. A recess 326 for receiving from the front end 323 side of the main cylinder portion 320;
A circular sliding surface 328 against which the projection 105 of the rear end part 1 that has come out of the recess 326 by pushing forward operation of the rear end part 1 against this biasing is abutted from the front end 323 side of the main cylinder part 320 is provided. Is formed.

  In the example shown in the drawing, a circumferential inner flange 329 projecting inward is formed at the rear end 324 of the main cylinder portion 320. On the other hand, the front end portion 100 of the rear end part 1 is configured to have a substantially cylindrical shape, and has a circumferential outer flange portion 104 that protrudes outward from the base portion of the protruding portion 102. In the illustrated example, the revolving outer flange portion 104 is hooked on the revolving inner flange portion 329 from the inside of the main cylinder portion 320, so that the rear end part 1 is placed on the main cylinder portion 320. The front end portion 100 is combined. In the illustrated example, the inner cylindrical portion 329 of the main cylinder portion 320 is recessed from the front end portion 323 side of the main cylinder portion 320, and the protruding end surface 330 of the circular inner flange portion 329 is also provided. An open recess 326 is formed, and the rear end part 1 projects toward the rear end side from the surface of the circumferential outer flange 104 facing the rear end part of the rear end part 1. A protrusion 105 is formed. The protrusion 105 enters the recess 326 in the non-rotation position by the bias of the spring 322, and the intermediate part 3 is in the non-rotation position regardless of the rotation bias of the spring 322. That is, the other member 5 ′ is not rotated. From this state, when the rear end part 1 is pushed and advanced to the position where the projection 105 is pulled out from the recess 326 against the bias of the spring 322, the intermediate part 3 is automatically moved by the rotation bias of the spring 322. Is rotated. During this rotation, the protruding projection 105 is abutted against the flange surface of the circular inner flange 329 by the biasing of the spring 322. It is never done. That is, in the example shown in the figure, the collar surface of the circumferential inner collar portion 329 functions as the circumferential sliding surface 328.

  In the illustrated example, ribs 312 and 331 along the axial direction of the intermediate part 3 are formed on the outer surface of the intermediate part 3 and the third through hole 501 of the third part 500 is formed. A groove 502 into which the ribs 312 and 331 are fitted is formed in the wall by inserting the intermediate part 3 into the third through hole 501, and the axis of the rear end part 1 is formed on the outer surface of the rear end part 1. A rib 106 extending in the direction is formed, and a groove 402 into which the rib 106 is fitted in the hole wall of the first through hole 401 of the first portion 400 by inserting the rear end part 1 into the first through hole 401. Is formed. Accordingly, the intermediate part 3 constituting the shaft unit J is fixed to the third portion 500 of the other member 5 ′, and the rear end part 1 is allowed to move only in the direction along the hole axis of the first through hole 401. In this state, it is assembled to the first portion 400 of the one member 4 ′.

With this configuration, according to the shaft unit J according to this embodiment,
(1) First, the front end part 2 is inserted into the second through hole 411 from the state in which the third portion 500 of the other member 5 ′ is placed between the first portion 400 and the second portion 410 of the one member 4 ′. The intermediate part 3 is inserted into the third through hole 501 and the rear end part 1 is inserted into the first through hole 401 so that the shaft unit J is inserted into these through holes 401, 411, 501. Thus, the one member 4 ′ and the other member 5 ′ can be combined so as to be rotatable with one touch. Further, as long as the rear end part 1 is not pushed forward and operated against the urging force of the urging means 321, it is possible to prevent such rotation.
(2) Next, when such rotation is required, the rear end part 1 is pushed forward and operated against the urging force of the urging means 321 to move from the recess 326 of the main cylinder part 320 to the rear end part 1. By removing the projection 105, the rotation can be performed with one touch by the urging of the urging means 321. At the same time, the braking means 301 can apply braking to the rotation.
(3) Further, when the other member 5 ′ rotated to the rotation end position is operated to rotate to the position before the rotation start, the intermediate part 3 is rotated toward the non-rotation position and is not rotated. When rotated to the position, the protrusion 105 of the rear end part 1 enters the recess 326 of the main cylinder part 320 again by the biasing means 321 and the intermediate part 3 remains in the unrotated position. Is done. That is, the state of the other member 5 ′ returned to the position before the start of rotation is maintained again.

  Further, in this embodiment, the side wall surface 327 of the recess 326 in the main cylinder portion 320 causes the intermediate part 3 to be rotated and biased by the biasing means 321 by pushing the forward movement of the rear end part 1. While turning, the inclined surface is inclined in such a direction that the projection 105 of the rear end part 1 is extracted from the recess 326.

  Thereby, in this embodiment, in the process in which the protrusion 105 is pulled out from the recess 326 accompanying the pushing operation of the rear end part 1 and moving forward, the intermediate part 3 is slightly removed in advance, that is, the other member 5 ′. Thus, when the rotation resistance at the start of rotation is the highest, the other member 5 ′ can be reliably rotated by supplementing the biasing force. Further, when the intermediate part 3 is returned to the non-rotation position by the operation of returning the other member 5 ′ to the position before the rotation start, the protrusion 105 is formed in the recess 326 by the urging of the urging means 321 at the final stage. Can be easily pulled in.

  Further, in this embodiment, the side portion 108 is laterally moved from the unlocked position where the side portion 108 does not protrude sideways from the side surface of the rear end portion 101 to the rear end portion 101 of the rear end part 1. The lock body 107 is assembled so as to be movable up to the lock position protruding to the front.

  In the illustrated example, the rear end portion 101 of the rear end part 1 is fitted with the other end portion of the main shaft 113 provided with the circumferential outer flange portion 104 and the protrusion 105 at one end portion. The knob body 115 is configured by being fitted into the fitting hole 116 of the knob body 115 having a substantially cylindrical shape provided with the hole 116 at the front end. In the illustrated example, the rib 106 is formed on the knob body 115. In the illustrated example, the knob body 115 is formed with a hole 118 that is opened at the side of the knob body 115 and extends inwardly of the knob body 115, and the knob body 115 is formed on the rear end surface of the knob body 115. A groove 119 having a groove width narrower than the hole width of the hole 118 opened to the outside at the side portion is formed from the center portion of the 115 to the side portion. The groove 119 is communicated with the hole inside the knob body 115 at a position approximately in the middle of the hole in the width direction.

  On the other hand, the lock body 107 is configured to have a disk shape having substantially the same diameter as the outer diameter of the knob body 115, and the head 110 and the groove 119 entering the hole 118 are formed on one surface thereof. And a leg portion 109 integrally provided with a neck portion 111 passing therethrough.

  In the illustrated example, the knob body 115 is covered with the lock body 107 so that the rear end surface of the knob body 115 is covered with the head 110 of the leg 109 inserted into the hole 118. The lock body 107 is combined. That is, the head portion 110 of the lock body 107 is inserted into the hole 118 of the knob body 115 from the side so that the neck portion 111 of the lock body 107 passes through the groove 119 of the knob body 115, and the lock body 107 and the knob body 115. Is combined. As a result, the lock body 107 can be slid between the unlocked position and the locked position. Further, in the illustrated example, a positioning projection 112 is formed on the neck 111 of the leg 109 of the lock body 107, and a gap is formed in the groove 119 of the knob body 115 in the extending direction of the groove 119. The two positioning recesses 120 and 120 are formed, and the side portion 108 of the lock body 107 is located on the knob body 115 at the position where the positioning projection 112 is placed in the positioning recess 120 on the center side of the knob body 115. If the lock body 107 is slid from this position without protruding from the side surface (that is, in an unlocked state / FIG. 13), the positioning protrusion 112 comes out of the positioning recess 120 mainly due to elastic deformation on the knob body 115 side. Due to the elastic return at the position where the positioning protrusion 112 enters the positioning recess 120 on the end side of the rear knob body 115, this positioning recess So that the positioning projection 112 enters the 120. Then, the side portion 108 of the lock body 107 protrudes from the side surface of the knob body 115 at a position where the positioning protrusion 112 is placed in the positioning recess 120 on the end side of the knob body 115. (In other words, in the locked state / FIG. 14) In the illustrated example, the rear end part 1 can be pushed into the first through hole 401 when the lock body 107 is in the unlocked position. In a state where 107 is in the locked position, the protruding portion of the lock body 107 hits the hole 403 of the first through hole 401 so that the pushing-in cannot be performed.

  Thereby, in this embodiment, even if a pushing force is applied to the lock body 107 by sliding the lock body 107 to the lock position in a state where the intermediate part 3 is in the non-rotating position. The lock body 107 is brought into contact with the hole 403 of the first through-hole 401 to prevent the lock body 107 from moving in the pushing direction, that is, pushing the forward movement of the rear end part 1. It is possible to prevent the part 3, that is, the other member 5 ′ from being rotated.

  In this embodiment, a protrusion 114 is formed on the other end portion of the main shaft 113 constituting the rear end part 1, and the fitting hole 116 of the knob body 115 is formed on the inner wall of the fitting hole 116. A recess 117 into which the projection 114 fits is formed on each of the entrance side and the back side of the fitting hole 116, and the projection 114 usually fits into the recess 117 on the back side. If the other member 5 ′ is erroneously rotated from the state where the lock body 107 is positioned at the lock position, the intermediate part 3 is rotated by the rotation of the other member 5 ′. However, in this case, the projection 114 comes out of the recess 117 on the back side due to elastic deformation, and the projection 114 is inserted into the recess 117 on the entrance side. The main shaft 113 is allowed to move to the position where it enters. Thereby, the shaft unit J is prevented from being damaged by such an erroneous operation.

  Moreover, the provision of a desired elastic deformation characteristic to the portion to be elastically deformed in the shaft unit J described above can be easily ensured by using a member having such a portion as a plastic molded product.

(3) It is comprised from the shaft unit J demonstrated above.

  In the illustrated example, the one container structure 4 is configured as a box-shaped main body having an upper surface opening. The main body has side plates 421 at four sides of a substantially square bottom plate 420. And it has the overhang | projection part 422 which makes the column shape which distribute | arranged the axis | shaft horizontally at the both ends of the outer surface of the side plate 421 formed along the one side part, and said 1st passage is carried out to one side of this overhang part 422. A hole 401 is formed on the other side and the second through hole 411 is formed on the other side. That is, in the illustrated example, the one container structure 4 is the one member 4 ′, one of the overhanging portions 422 is the first portion 400, and the other of the overhanging portions 422 is the second portion 410. Yes.

  Moreover, in the example of illustration, the said other container structure 5 is comprised as a box-shaped cover body of a lower surface opening. Such a lid has side plates 511 on four sides of a substantially square upper plate 510. And it has the projecting part 512 which makes the column shape which distribute | arranged the axis line horizontally in the center part of the outer surface of the side plate 511 formed along the one side part, and the said 3rd through-hole 501 is in this projecting part 512. Is formed. That is, in the illustrated example, the other container structure 5 is the other member 5 ′, and the overhanging portion 512 is the third portion 500.

And this cosmetic container Y puts the 3rd part 500 between the said 1st part 400 and the 2nd part 410, and has the 1st through-hole 401, the 3rd through-hole 501, and the 2nd through-hole 411. In the combined state in the state of communication,
The shaft unit J is inserted into the through holes 401, 411, 501 communicated, and the one container constituent body 4 and the other container constituent body 5 are rotatably assembled and configured.
In a state where the intermediate part 3 of the shaft unit J is in the non-rotating position, the one container structure 4 and the other container structure 5 are overlapped with each other. (FIG. 1) That is, in a state where the intermediate part 3 is in the non-rotating position, the internal space of the one container structure 4 is closed by the other container structure 5.

  Thus, according to the cosmetic container Y, by inserting the shaft unit J through the first through hole 401 and the second through hole 411 of the one container component 4 and the third through hole 501 of the other container component 5. Both container constituent bodies 4 and 5 can be assembled so as to be rotatable with one touch.

  At the same time, it is possible to stably maintain the state where the one container structure 4 and the other container structure 5 overlap each other. Further, by pushing the rear end part 1 of the shaft unit J with the hand holding the cosmetic container Y and moving forward, the other container component 5 is automatically braked in the opening direction from the overlapped state. It can be rotated. Furthermore, the automatic rotation of the other container component 5 can be stopped halfway, and the other container component 5 is moved while giving a free stop action to the other container component 5 from the stop position. It can be rotated. Further, by moving the lock body 107 of the shaft unit J to the lock position in a state where the one container structure 4 and the other container structure 5 overlap each other, the rear end part 1 is unexpectedly pushed and the other container It is possible to prevent the structure 5 from opening.

  In the illustrated example, the inner lid body 6 is a substantially rectangular plate having a size that fits in the internal space when the one container structure 4 and the other container structure 5 are overlapped. It is comprised so that a shape may be made. Further, in the example shown in the figure, a ring body 602 is provided at one side of the inner lid body 6 so that the axis line is arranged substantially horizontally. Then, one of the pair of ring bodies 602 and 602 is stored between the first portion 400 and the third portion 500, and the other is stored between the third portion 500 and the second portion 410. Thus, the intermediate part 3 of the inserted shaft unit J is passed through the inside of the pair of ring bodies 602 and 602 by this insertion. That is, in the illustrated example, the pair of ring bodies 602 and 602 serve as the fourth portion 600, and the inside thereof serves as the fourth through hole 601.

  At the same time, in the illustrated example, the edge portion 603 between the pair of ring bodies 602 and 602 of the inner lid body 6 is in a state where the one container constituent body 4 and the other container constituent body 5 overlap each other. In addition, the other side of the container component 5 protrudes outward from the notch 514 of the side plate in which the third portion 500 is formed, and is the outer surface of the third portion 500 in this state, with respect to the edge portion 603. Thus, the abutting portion 513 for linkage projecting downward is formed at a position where the position differs by approximately 90 degrees.

  Thereby, in this embodiment, the inner lid body 6 is also rotated in the same direction from the middle of the rotation in accordance with the rotation of the other container constituting body 5 by the biasing of the biasing means 321. Can do.

  In the example shown in the figure, when the other container component 5 is rotated approximately 90 degrees by the urging force of the urging means 321, the linkage abutment 513 abuts against the edge 603 of the inner lid 6, and from this state Further, when the other container component 5 is rotated, the inner lid body 6 is rotated in the same direction by the amount of rotation. (Fig. 2 to Fig. 4)

  The foundation is placed in the one container component 4 of the cosmetic container Y, a mirror is attached to the side of the inner lid 6 facing the bottom plate 420 of the one container component 4, and the upper surface of the inner lid 6 and the other container configuration are arranged. When a puff is placed between the upper plate 510 of the body 5 and the rear end part 1 of the shaft unit J is pushed and advanced using the fingers of the hand on the side holding the cosmetic container Y, first the other container structure 5 automatically rises to a position of approximately 90 degrees by the urging force of the urging means 321 and can use the puff with the other hand. From this position, the other container component 5 is given a free stop action, and the other container component 5 can be opened to an arbitrary opening position. At the same time, the inner lid body 6 also rises, and it is possible to make makeup by positioning the inner lid body 6 at an appropriate angle to capture the face.
