Description

The present invention relates to a compact container.

As a compact container, a configuration generally includes a middle plate in which the contents are stored, a container body in which the middle plate is stored through an opening that opens upward, and a lid that openably closes the container body. It is known (see, for example, Patent Document 1 below).

Japanese Unexamined Patent Publication No. 2013-153960

However, in the above-mentioned conventional compact container, for example, when the contents are wiped with a puff or the like, the contents near a fixed position may be unconsciously wiped each time due to the user's own habits and usability. is there. However, in this case, the contents tend to decrease around the wiped position, and the contents tend to decrease unevenly, which is a so-called one-sided reduction phenomenon.

Conventionally, when such unevenness occurs, it is necessary to take measures such as consciously changing the wiping direction, removing the inner plate from the inside of the container, and then reinserting it in an appropriate direction. there were. Therefore, it is not easy to use and may be stressful for the user.

The present invention has been made in view of such circumstances, and an object of the present invention is to make it difficult for the contents to be worn out, to be easy to use, and to reduce stress on the user. It is to provide a compact container that can be used.

(1) The compact container according to the present invention is connected to a middle plate in which the contents are stored, a container body having a storage portion in which the middle plate is housed, and the container body so as to be relatively movable. The lid body that closes the accommodating portion so as to be openly arranged is arranged between the container body and the middle plate so as to be relatively movable with respect to the container body and the middle plate, and the lid body with respect to the container body. The inner plate is provided with a movable piece that reciprocates between the first position and the second position with the movement of the container, and the inner plate is made rotatable around the central axis of the container body extending in the vertical direction. A first engaging portion is formed on one piece, and a second engaging portion with which the first engaging portion engages is formed on the middle plate, and the first engaging portion and the second engaging portion are formed. The portion is characterized in that, as the movable piece moves, the middle plate is rotated in cooperation with each other toward one side in the circumferential direction orbiting around the central axis.

According to the compact container according to the present invention, each time the lid is moved relative to the container body when the contents are used, the movable piece is moved between the first position and the second position in conjunction with the lid. Can be moved. As a result, the reciprocating movement of the movable piece is converted into a rotational movement around the central axis by utilizing the first engaging portion of the movable piece and the second engaging portion of the inner plate that engage with each other, and the inner plate is formed. It can be rotated toward one side in the circumferential direction.

Therefore, the inner plate can be rotated toward one side in the circumferential direction only by the user opening and closing the lid, so that the contents are wiped in the same manner as before by using, for example, a puff or the like. Even so, it can be used to wipe the contents evenly. Therefore, uneven reduction is unlikely to occur, and the contents can be used up while being reduced in a nearly uniform state. Therefore, it is easy to use and the stress on the user can be reduced.
In particular, since the inner plate can be rotated in conjunction with the opening / closing operation of the lid, for example, even if the user does not intend or be aware of how to use it so that the contents are uniformly reduced, it depends on these intentions and consciousness. It is possible to use it so that the contents are naturally reduced evenly.

(2) The movable piece is arranged between the bottom of the middle plate of the middle plate and the bottom wall of the container body, and intersects the central axis in a plan view from the direction of the central axis. The first engaging portion is movable along the radial direction, and the first engaging portion has an engaging protrusion formed on the movable piece so as to project toward the bottom of the inner plate, and the second engaging portion is The bottom of the inner plate is formed so as to extend in the circumferential direction, and has a cam groove that movably accommodates the engaging protrusion, and the engaging protrusion and the cam groove are said from the first position. With the movement of the movable piece to the second position and the movement of the movable piece from the second position to the first position, the middle plate is directed to one side in the circumferential direction in cooperation with each other. You may move it.

In this case, the movable piece moves in conjunction with the opening / closing operation of the lid, so that the engaging protrusion moves relatively in the cam groove. As a result, the linear movement of the movable piece along the radial direction can be appropriately converted into a rotational movement around the central axis, and the inner plate can be rotated toward one side in the circumferential direction. Further, since the movable pieces are arranged between the bottom of the inner plate and the bottom wall and the cam groove is formed on the bottom of the inner plate, these movable pieces and the cam groove can be made difficult to see from the outside. .. Therefore, the design can be improved.

(3) The cam groove includes a plurality of first cam grooves and a plurality of second cam grooves alternately arranged in the circumferential direction, and the first cam groove is directed from the outer side in the radial direction to the inner side in the radial direction. Therefore, the second cam groove is formed so as to extend toward the other side in the circumferential direction, and the second cam groove is formed so as to extend toward one side in the circumferential direction from the outer side in the radial direction to the inner side in the radial direction. The outer end of the first cam groove communicates with the outer end of the second cam groove adjacent to one side in the circumferential direction with respect to the first cam groove, and the inner end of the first cam groove is The engaging protrusion communicates with the inner end of the second cam groove adjacent to the other side in the circumferential direction with respect to the first cam groove, and the engaging protrusion is movable from the first position to the second position. With the movement of the piece, the movable piece moves from the outer end portion of the first cam groove toward the inner end portion, and with the movement of the movable piece from the second position to the first position. It may move from the inner end portion of the second cam groove toward the outer end portion.

In this case, when the movable piece moves in the radial direction from the first position to the second position with the opening / closing operation of the lid, the engaging protrusion moves from the outer end to the inner end of the first cam groove. Move in the first cam groove so as to face. At this time, the first cam groove extends from the outer side in the radial direction toward the inner side in the radial direction toward the other side in the circumferential direction. Therefore, by moving the engaging protrusion in the first cam groove, the rotational force toward one side in the circumferential direction can be transmitted to the inner plate, and the inner plate can be rotated in the same direction. Further, the engaging projection is moved to the inner end portion of the first cam groove so as to be located at the inner end portion of the adjacent second cam groove.
Therefore, when the movable piece moves in the radial direction from the second position to the first position with the opening / closing operation of the lid, the engaging protrusion is directed from the inner end portion to the outer end portion of the second cam groove. Move in the second cam groove. At this time, the second cam groove extends toward one side in the circumferential direction from the outer side in the radial direction toward the inner side in the radial direction. Therefore, by moving the engaging protrusion in the second cam groove, the rotational force toward one side in the circumferential direction can be transmitted to the inner plate, and the inner plate is rotated in the same direction as before. be able to. Further, the engaging projection is moved to the outer end portion of the second cam groove so as to be located at the outer end portion of the adjacent first cam groove.

In this way, by moving the movable piece between the first position and the second position according to the opening / closing operation of the lid, the engaging protrusion, the first cam groove, and the second cam groove are used to make the inside. The rotational force can be transmitted to the plate, and the inner plate can be stably and surely rotated to one side in the circumferential direction.

(4) When the movable piece moves from the first position to the second position, the contact portion between the outer end portion of the first cam groove and the outer end portion of the second cam groove is engaged. A first step portion for guiding the protrusion toward the first cam groove side is formed, and the communication portion between the inner end portion of the first cam groove and the inner end portion of the second cam groove is formed from the second position. When the movable piece is moved to the first position, a second step portion for guiding the engaging protrusion toward the second cam groove side may be formed.

In this case, when the movable piece is moved from the first position to the second position, the engaging projection can be appropriately guided to the first cam groove side by using the first step portion, and the second step portion can be used. When the movable piece is moved from the position to the first position, the engaging projection can be appropriately guided to the second cam groove side by using the second step portion. As a result, the inner plate can be rotated to one side in the circumferential direction more reliably.

(5) The bottom wall portion may be formed with a guide groove extending along the radial direction and accommodating the movable piece so as to be movable in the radial direction.

In this case, since the movable piece is housed in the guide groove, it is possible to guide the movement in the radial direction while restricting the movement of the movable piece in the circumferential direction. Therefore, the movable piece can be smoothly moved in the radial direction with less rattling, and as a result, the inner plate can be stably rotated to one side in the circumferential direction.

Further, a relief hole 17 that penetrates the peripheral wall portion 11 in the front-rear direction L1 is formed in a portion of the peripheral wall portion 11 that is located below the guide wall portion 15.

A vertical hole 18 is formed in the rear portion of the peripheral wall portion 11 so as to penetrate the bottom wall portion 10 and the peripheral wall portion 11 in the container axis O direction. The vertical hole 18 is formed so as to extend along the circumferential direction. In the illustrated example, the vertical hole 18 is formed so that the length along the circumferential direction is shorter than that of the window hole 13.
Further, in the portion of the bottom wall portion 10 located behind the guide protrusion 12, a guide groove 19 for movably accommodating the movable piece 6 described later is formed so as to extend along the radial direction. The guide groove 19 is formed in a rectangular shape longer in the front-rear direction L1 than in the left-right direction L2 in a plan view, and is opened upward and rearward through the vertical hole 18.

As shown in FIGS. 1 and 2, the lid 5 is formed in a circular shape in a plan view, is formed in an eclipse cylinder shape that closes the accommodating portion 3 from above, and is formed on the peripheral wall portion of the container body 4 via the hinge shaft 20. It is rotatably connected to 11. Therefore, the lid 5 is movably connected to the container body 4 by rotating in the front-rear direction L1 about the hinge shaft 20.

A hinge leg 21 is projected downward from a portion of the lid 5 located at the rear. The hinge leg 21 is housed in the vertical hole 18 of the container body 4. The lower end of the hinge leg 21 projects downward in a semicircular shape.
The hinge leg 21 is formed with a first hinge hole 22 that extends along the left-right direction L2 and opens on the inner wall surface of the vertical hole 18. The peripheral wall portion 11 of the container body 4 is arranged coaxially with the axis of the first hinge hole 22, and is formed with a second hinge hole 23 penetrating the peripheral wall portion 11 in the left-right direction L2 (see FIG. 3). ).
Further, the hinge leg portion 21 is formed with a housing groove 24 that opens downward and rearward from the lower end portion to the rear end portion.

The hinge shaft 20 is integrally inserted into the first hinge hole 22 and the second hinge hole 23. As a result, the entire lid 5 is rotatably connected to the container body 4 around the hinge shaft 20. Therefore, it is possible to open and close the lid 5 in the front-rear direction L1 around the hinge shaft 20.

An engaging piece 25 is projected downward from a portion of the lid 5 located in the front portion. The engaging piece 25 is formed in a plate shape that protrudes downward and extends in the left-right direction L2, and enters the engaging space 14 from above.

The middle plate 2 is rotatably arranged around the container shaft O in the accommodating portion 3 of the container main body 4, and is placed on the bottom wall portion 10. The inner plate 2 of the present embodiment is formed into a bottomed tubular inner frame 40 that opens upward and a bottomed tubular shape that opens upward, and is held inside the inner frame 40. It is provided with a middle plate main body 50.

The inner frame 40 is formed in a circular shape in a plan view, and projects upward from the inner frame bottom portion 41 placed on the bottom wall portion 10 of the container body 4 and the outer peripheral edge portion of the inner frame bottom portion 41. It is formed in a bottomed tubular shape provided with a middle frame tubular portion 42.
A through hole 43 is formed in the central portion of the middle frame bottom portion 41 so as to penetrate the middle frame bottom portion 41 in the vertical direction. The inner frame bottom portion 41 is placed on the bottom wall portion 10 with the guide protrusion 12 inserted inside the through hole 43. As a result, the inner frame 40 can rotate around the container shaft O while being guided by the guide protrusion 12.

The middle frame tubular portion 42 is formed in a two-stage tubular shape in which the upper end portion side has a diameter increased outward in the radial direction from the lower end portion side, and is arranged inside the peripheral wall portion 11 of the container body 4. The upper end of the inner frame cylinder portion 42 is close to or slidably in contact with the inside of the peripheral wall portion 11 of the container body 4. Therefore, the inner frame 40 is made to be able to rotate stably around the container shaft O with less rattling.

The middle plate main body 50 is integrally combined in the above-mentioned middle frame 40, for example, by being tightly fitted. Therefore, the entire inner plate 2 composed of the inner plate main body 50 and the inner frame 40 is rotatably arranged in the accommodating portion 3 around the container shaft O.
The contents are housed inside the inner plate body 50. Further, the middle frame bottom portion 41 functions as a middle plate bottom portion of the middle plate 2 as a whole.

An annular middle frame retainer 55 is attached to the peripheral wall portion 11 of the container body 4. The inner frame retainer 55 is formed so as to protrude outward in the radial direction from the retainer cylinder portion 56 fitted inside the peripheral wall portion 11 of the container body 4 and the upper end portion of the retainer cylinder portion 56. An annular flange piece 57, which is arranged on the upper end opening end of 11, is provided.
The pressing cylinder portion 56 is arranged above the middle frame cylinder portion 42, and the lower end portion is close to or slidably in contact with the upper end opening end of the middle frame cylinder portion 42 from above. As a result, the middle frame retainer 55 can be prevented from coming off upward while allowing the middle frame 40 to rotate.

As described above, the movable piece 6 is arranged between the container main body 4 and the middle plate 2 so as to be relatively movable with respect to the container main body 4 and the middle plate 2.

The movable piece 6 is housed so that the front end portion 6a side is located between the inner frame bottom portion 41 that functions as the inner plate bottom portion and the bottom wall portion 10 of the container body 4, and the rear end portion 6b side is formed on the hinge leg portion 21. It is arranged so as to be housed in the groove 24.

The rear end portion 6b side of the movable piece 6 is locked in the accommodating groove 24. As a result, the movable piece 6 moves so as to be pushed out or pulled back with the opening / closing operation of the lid body 5, and moves in the radial direction between the bottom portion 41 of the inner frame and the bottom wall portion 10 of the container body 4. Is possible.
Examples of the method of locking the movable piece 6 to the accommodating groove 24 include adhesion and pinning, but the method is not particularly limited, and a known method may be adopted.

The movable piece 6 does not have to be separate from the lid 5, and may be formed integrally with the lid 5. In this case, for example, the lid 5 and the movable piece 6 can be integrally formed by insert molding using the movable piece 6 as an insert product. Therefore, in this case, the movable piece 6 can be integrally fixed (locked) to the accommodating groove 24 by insert molding.

The front end portion 6a side of the movable piece 6 is movably housed in the guide groove 19 formed in the bottom wall portion 10 of the container body 4. As a result, the movable piece 6 can move in the radial direction while the movement in the circumferential direction is restricted.

The movable piece 6 configured as described above has a first position P1 shown in FIG. 1 in which the front end portion 6a side is located most rearward when the lid body 5 is closed, and a front end when the lid body 5 is opened. It reciprocates in the radial direction between the second position P2 shown in FIG. 2 in which the portion 6a side is located on the most front side and the lid body 5 is opened and closed.

As shown in FIGS. 1 and 4, the movable piece 6 is formed with a first engaging portion 60. On the other hand, on the inner plate 2 side, a second engaging portion 70 with which the first engaging portion 60 engages is formed. The first engaging portion 60 and the second engaging portion 70 function as a so-called cam mechanism in which the middle plate 2 is rotated around the container axis O in cooperation with each other as the movable piece 6 moves. ..
In the present embodiment, a case where the middle plate 2 is rotated in the first rotation direction M1 which is counterclockwise in the top view of the compact container 1 will be described as an example. However, the rotation direction of the middle plate 2 is not limited to this case, and may be rotated in the second rotation direction M2 which is clockwise.

The first engaging portion 60 has an engaging protrusion 61 protruding upward from the front end portion 6a of the movable piece 6. The engaging projection 61 is, for example, an engaging pin formed in a columnar shape, and is integrally formed with, for example, a movable piece 6. However, the engaging protrusion 61 may be a cam follower or a roller follower formed separately from the movable piece 6.

The movable piece 6 and the engaging protrusion 61 described above have the flexibility of being elastically deformable by moving with the opening / closing operation of the lid 5, and the deformation (shaving) that can occur due to the movement in the cam groove 71 described later. Etc.), it is preferable to form a material that has both strength (rigidity) for suppressing. Examples of such a material include a synthetic resin material such as polypropylene (PP). However, the material of the movable piece 6 and the engaging protrusion 61 is not limited to this case, and a synthetic resin material other than PP or a material other than the synthetic resin material may be used.

The second engaging portion 70 is formed on the lower surface side of the inner frame bottom portion 41 so as to extend in the circumferential direction, and includes a cam groove 71 that movably accommodates the engaging projection 61. Then, the engaging protrusion 61 and the cam groove 71 move with the movement of the movable piece 6 from the first position P1 to the second position P2 and the movement of the movable piece 6 from the second position P2 to the first position P1. The middle plate 2 is moved in the first rotation direction M1 in cooperation with each other.

The cam groove 71 will be described in detail.
The cam groove 71 includes a plurality of first cam grooves 72 and a plurality of second cam grooves 73 alternately arranged in the circumferential direction.
The first cam groove 72 is formed so as to extend in the second rotation direction M2 from the outer side in the radial direction to the inner side in the radial direction. Contrary to the first cam groove 72, the second cam groove 73 is formed so as to extend in the first rotation direction M1 from the outer side in the radial direction toward the inner side in the radial direction.

The outer end portion of the first cam groove 72 communicates with the outer end portion of the second cam groove 73 adjacent to the first cam groove 72 on the M1 side in the first rotation direction. Further, the inner end portion of the first cam groove 72 communicates with the inner end portion of the second cam groove 73 adjacent to the first cam groove 72 in the second rotation direction M2.
As a result, the plurality of first cam grooves 72 and the second cam grooves 73 alternately arranged in the circumferential direction communicate with each other. Therefore, the engaging projection 61 can move over the entire cam groove 71 while alternately moving between the first cam groove 72 and the second cam groove 73.

In the illustrated example, a first extension groove 74 extending outward in the radial direction is formed at a communicating portion between the outer end portion of the first cam groove 72 and the outer end portion of the second cam groove 73. ing. The first extension groove 74 is open to the outside in the radial direction. Further, a second extension groove 75 extending inward in the radial direction is formed at the communicating portion between the inner end portion of the first cam groove 72 and the inner end portion of the second cam groove 73.

With respect to the cam groove 71 configured as described above, the engaging projection 61 is provided from the outer end portion of the first cam groove 72 as the movable piece 6 moves from the first position P1 to the second position P2. It is possible to move toward the inner end and move from the inner end to the outer end of the second cam groove 73 as the movable piece 6 moves from the second position P2 to the first position P1. It is possible.

In the present embodiment, the groove depth of the first cam groove 72 is formed to be the deepest on the outer end side and the shallowest on the inner end side, and from the outer end side to the inner end side. It is formed so that it gradually becomes shallower toward it.
On the other hand, the groove depth of the second cam groove 73 is such that the inner end side is formed deepest, the outer end side is formed the shallowest, and the inner end side is directed toward the outer end side. Therefore, it is formed so as to gradually become shallower.

As described above, since the groove depths of the first cam groove 72 and the second cam groove 73 have changed, the communication portion between the outer end portion of the first cam groove 72 and the outer end portion of the second cam groove 73. Is formed with a first step portion 76 that guides the engaging projection 61 toward the first cam groove 72 when the movable piece 6 moves from the first position P1 to the second position P2. Further, in the communicating portion between the inner end portion of the first cam groove 72 and the inner end portion of the second cam groove 73, the engaging protrusion 61 is formed when the movable piece 6 is moved from the second position P2 to the first position P1. A second step portion 77 is formed to guide the sword to the second cam groove 73 side.

(Action of compact container)
Next, a case where the compact container 1 configured as described above is used will be described.
In this case, the push piece 30 is operated to release the locked state (closed state) of the lid body 5. Specifically, the operation wall portion 31 is pressed backward from the state shown in FIG. 1, and the entire push piece 30 is moved rearward. As a result, the release protrusion 32 can be moved backward while being elastically deformed along the inclined surface 15a of the guide wall portion 15, and the second engagement protrusion 26 is pushed up from below to be separated from the first engagement protrusion 16. be able to.
As a result, the engagement between the first engaging projection 16 and the second engaging projection 26 can be disengaged, and the lid body 5 can be opened.

Next, by rotating the entire lid 5 around the hinge shaft 20, the lid 5 can be opened rearward as shown in FIG. 2, and the lid 5 is separated from the container body 4. be able to. As a result, the accommodating portion 3 of the container body 4 can be opened, and the contents can be used by using the cosmetic coating tool 7.

In particular, according to the compact container 1 of the present embodiment, each time the lid 5 is opened / closed (relatively moved) with respect to the container body 4 when the contents are used, the movable piece 6 is interlocked with the lid 5. It can be moved between the first position P1 and the second position P2. As a result, the reciprocating movement of the movable piece 6 is converted into a rotary motion around the container shaft O by utilizing the engaging protrusion 61 on the movable piece 6 side and the cam groove 71 on the middle plate 2 side that engage with each other. The middle plate 2 can be rotated in the first rotation direction M1.
Therefore, the middle plate 2 can be rotated in the first rotation direction M1 only by the user opening and closing the lid body 5. Therefore, for example, the cosmetic coating tool 7 is used to provide the same contents as before. Even if you wipe the contents, you can use it while wiping the contents evenly.

This will be described in more detail.
By performing the opening / closing operation of the lid body 5, the movable piece 6 can be moved in the radial direction in conjunction with the opening / closing operation, so that the engaging projection 61 is relatively moved in the cam groove 71. Can be done. Therefore, the linear movement of the movable piece 6 along the radial direction can be appropriately converted into a rotational movement around the container axis O, and the middle plate 2 can be rotated in the first rotation direction M1.

Specifically, when the lid 5 is opened as shown in FIG. 2, the movable piece 6 is moved inward in the radial direction from the first position P1 shown in FIG. 1 to the second position P2 shown in FIG. Can be moved to. Therefore, the engaging protrusion 61 is moved along the inside of the first cam groove 72 so as to go from the first point N1 which is the outer end portion of the first cam groove 72 shown in FIG. 4 to the second point N2 which is the inner end portion. Can be moved. At this time, the first cam groove 72 extends from the outer side in the radial direction toward the inner side in the radial direction toward the M2 side in the second rotation direction.

Therefore, as shown in FIG. 5, the engaging protrusion 61 moves in the first cam groove 72 to rotate the middle plate 2 in the first rotation direction M1 as shown by the arrow F1 shown in FIG. The force can be transmitted and the inner plate 2 can be rotated in the same direction. Further, the engaging protrusion 61 moves to the inner end portion (second point N2) of the first cam groove 72, so that the engaging projection 61 is located at the inner end portion of the adjacent second cam groove 73.

Next, when the lid 5 is closed after using the contents, the movable piece 6 is moved radially outward from the second position P2 shown in FIG. 2 to the first position P1 shown in FIG. Can be made to. Therefore, the engaging projection 61 is directed from the second point N2, which is the inner end of the second cam groove 73 shown in FIG. 5, to the third point N3, which is the outer end of the second cam groove 73 shown in FIG. As such, it can be moved along the inside of the second cam groove 73. At this time, the second cam groove 73 extends from the outer side in the radial direction toward the inner side in the radial direction toward the M1 side in the first rotation direction.

Therefore, by moving the engaging protrusion 61 in the second cam groove 73, it is possible to transmit the rotational force toward the first rotation direction M1 to the middle plate 2 as shown by the arrow F2 shown in FIG. The middle plate 2 can be rotated in the same direction as before. Further, the engaging projection 61 moves to the outer end portion (third point N3) of the second cam groove 73, so that the engaging projection 61 is located at the outer end portion of the adjacent first cam groove 72.

Therefore, by subsequently opening and closing the lid 5 again, the above-mentioned operation can be repeated, and the middle plate 2 can be rotated in the first rotation direction M1.
In this way, by moving the movable piece 6 between the first position P1 and the second position P2 in accordance with the opening / closing operation of the lid body 5, the engaging projection 61, the first cam groove 72, and the second cam groove The rotational force can be transmitted to the inner plate 2 by using 73, and the inner plate 2 can be stably and surely rotated in the first rotation direction M1.

Therefore, uneven reduction is unlikely to occur, and the contents can be used up while being reduced in a nearly uniform state. Therefore, it is easy to use and the stress on the user can be reduced.
In particular, since the inner plate 2 can be rotated in conjunction with the operation of the lid 5 (opening operation and closing operation), the user does not intend or be aware of how to use it so that the contents are uniformly reduced, for example. However, it is possible to use it so that the contents are naturally reduced evenly, regardless of these intentions and consciousness.

As described above, according to the compact container 1 of the present embodiment, it is possible to make it difficult for the contents to be unevenly reduced, it is easy to use, and the stress on the user can be reduced.

Further, in the case of the present embodiment, since the movable piece 6 is housed in the guide groove 19, it is possible to guide the movement in the radial direction while restricting the movement of the movable piece 6 in the circumferential direction. it can. Therefore, the movable piece 6 can be smoothly moved in the radial direction with less rattling, and as a result, the middle plate 2 can be stably rotated in the first rotation direction M1.
Moreover, when the movable piece 6 is moved from the first position P1 to the second position P2 (when the lid 5 is opened), the engaging projection 61 is moved to the first cam groove 72 side by using the first step portion 76. When the movable piece 6 is moved from the second position P2 to the first position P1 (when the lid 5 is closed), the engaging protrusion is used by using the second step portion 77. 61 can be appropriately guided to the second cam groove 73 side. Therefore, the middle plate 2 can be rotated in the first rotation direction M1 more reliably.

In the present embodiment, the engaging projection 61 is guided in an arbitrary direction by using the first step portion 76 and the second step portion 77, but the structure is not limited to such a step structure.
For example, when the engaging protrusion 61 is moved from the first point N1 which is the outer end portion of the first cam groove 72 to the second point N2 which is the inner end portion, the engaging protrusion 61 moves to the first cam groove 72. The first cam groove 72 and the second cam groove 73 are formed so as to stay at a position deviated from the center of the communication portion between the inner end portion of the second cam groove 73 and the inner end portion of the second cam groove 73 toward the second cam groove 73. It doesn't matter. Even in this case, the engaging projection 61 can be subsequently guided to the second cam groove 73 side.

Further, since the movable piece 6 is arranged between the middle frame bottom portion 41 and the bottom wall portion 10 and the cam groove 71 is formed in the middle frame bottom portion 41, these movable pieces 6 and the cam groove 71 are externally formed. It can be made difficult to see from. Therefore, the design can be improved.
