Description

The present invention relates to a compact container.

As a compact container, a configuration is known to include 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 an inner frame for holding the middle plate in the container body. (For example, see Patent Document 1 below). In this type of compact container, the inner frame is provided with a recess for engaging the engaging pin formed in the inner plate and a leaf spring for urging the inner plate upward with respect to the inner plate. There is.

According to this configuration, at the mounting position of the middle plate, the middle plate is restricted from rising with respect to the inner frame by engaging the engaging pin with the recess. On the other hand, when replacing the middle plate, the middle plate is rotated with respect to the middle frame while the middle plate is once pushed into the middle frame. Then, the engagement between the engaging pin and the recess is released. After that, when the hand is released from the middle plate, the middle plate is raised by the urging force of the leaf spring. As a result, the upper end of the inner plate protrudes upward from the inner frame, so that the inner plate can be removed.

Japanese Unexamined Patent Publication No. 2000-102414

However, in the above-mentioned compact container, when the inner plate is replaced, it is necessary to push and rotate the inner plate itself. Therefore, there is still room for improvement in workability when replacing the inner plate.

Therefore, an object of the present invention is to provide a compact container capable of improving workability at the time of exchanging the inner plate.

In order to solve the above problems, the present invention proposes the following means.
The compact container according to one aspect of the present invention surrounds the inner plate in which the contents are stored, the container body in which the inner plate is housed, and the inner plate in the container body, and surrounds the inner plate in the vertical direction. The container body and the middle plate are engaged with each other in the circumferential direction around the axis, and the container body and the middle plate are provided around the axis of the middle plate with respect to the container body. The container body and the rotating member are provided with a vertical restricting portion for restricting the vertical movement of the rotating member with respect to the container body by engaging with each other in the vertical direction. The rotating member engages with the engaged portion formed on the middle plate, raises the middle plate with the rotation around the axis with respect to the middle plate, and brings the middle plate to the uppermost position. It is provided with an engaging portion that is disengaged from the engaged portion at a certain time.

According to this aspect, the middle plate can be moved to the uppermost position only by the rotation operation of the rotating member. As a result, the workability at the time of exchanging the middle plate can be improved as compared with the case where the exchanging operation is performed by the two operations of the pushing operation and the rotating operation as in the conventional case.
Moreover, in this embodiment, since the inner plate can be moved to the uppermost position without directly touching the inner plate, it is possible to suppress an excessive external force from acting on the inner plate. As a result, it is possible to suppress the influence on the contents, especially when the inner plate is attached.

In the compact container according to the above aspect, the container body and the rotating member may include a lower end engaging portion that engages with each other when the middle plate is in the lowermost position.
According to this aspect, the middle plate can be held by the lower end engaging portion at the lowermost end position. As a result, for example, when the contents are taken out, it is possible to prevent the inner plate from rattling with respect to the rotating member and the inner plate from suddenly rotating toward the uppermost position with respect to the rotating member.

In the compact container according to the above aspect, the container body and the rotating member are in contact with each other in the circumferential direction when the middle plate is at the lowermost position and the uppermost position, and the rotating member with respect to the container body. A rotation limiting unit that limits rotation may be provided.
According to this aspect, the rotation range of the rotating member with respect to the container body is limited between the lowermost position and the uppermost end position. As a result, the amount of operation of the rotating member at the time of replacement can be easily determined, and workability at the time of replacement can be improved.

In the compact container according to the above aspect, the rotating member includes a support cylinder on which the engaging portion is formed and an operating portion that protrudes upward from the supporting cylinder, and the operating portion is viewed from above and below. The radial inward facing surface that intersects the axis may be formed in an arc shape that smoothly connects to the upper end edge of the middle plate when the middle plate is at the lowermost position.
According to this aspect, since the rotating member can be operated via the operating portion, it is possible to prevent a hand or the like from touching the inner plate during the replacement work.
Moreover, in this embodiment, the operation portion and the upper end edge of the inner plate are smoothly connected, so that the surface of the operation portion facing inward in the radial direction guides the contents in the inner plate when scooping up the contents with, for example, a puff. Functions as. This makes it easier to take out the contents. Further, since the operation unit and the upper surface of the inner plate have an integrated appearance, the design can be improved.

In the compact container according to the above aspect, the engaging portion and the engaged portion may be multi-threaded screws.
According to this aspect, the amount of movement of the inner plate with respect to the amount of rotation of the rotating member can be increased as compared with the configuration in which the engaging portion and the engaged portion are formed in a single screw.

In the compact container according to the above aspect, the engaging portion includes a first screw thread arranged at intervals in a first region in the circumferential direction of the inner peripheral surface of the rotating member, and the inside of the rotating member. The peripheral surface includes a second thread arranged at intervals in a second region in the circumferential direction, and the upper end edge of the second thread is located below the upper edge of the first thread. You may be doing it.
According to this aspect, in the process of shifting the middle plate from the lowermost position to the uppermost end position, after the engagement between the second thread and the engaged portion is released, the first screw thread and the engaged portion are engaged. The engagement with is released. That is, since the positions of the upper end edges of the first screw thread and the second screw thread are different, the middle plate is tilted by, for example, its own weight or the like when the engagement between the first screw thread and the engaged portion is released. Specifically, since the lower end edge of the engaged portion is mainly supported by the upper end edge of the second thread, the portion of the inner plate located in the first region rises upward.
As a result, it is possible to easily insert a hand between the inner plate and the rotating member, and workability at the time of replacement can be improved.

According to the compact container according to the above aspect, workability at the time of exchanging the inner plate can be improved.

In the following description, the central axis of the container body 2 is referred to as the container axis O, and the direction along the container axis O is referred to as the vertical direction. In this case, in the compact container 1, the bottom 11 side of the container body 2 along the vertical direction is referred to as the lower side, and the top wall portion 31 side of the lid 3 is referred to as the upper side. Further, in a plan view seen from the vertical direction, the direction intersecting the container axis O is called the radial direction, and the direction rotating around the container axis O is called the circumferential direction.

As shown in FIG. 3, the container body 2 has a circular shape in a plan view and is formed in a box shape that opens upward. The lid body 3 described above is rotatably connected to a part of the container body 2 in the circumferential direction via a hinge portion 7. In the present embodiment, the container body 2 and the lid 3 form an outer container 8 for accommodating the rotating member 4, the inner plate 5, and the like. In the following description, among the radial directions, the direction connecting the container shaft O and the hinge portion 7 shown in FIG. 2 is referred to as a front-rear direction, and the direction orthogonal to the front-rear direction is referred to as a left-right direction. Further, in the front-rear direction, the side closer to the hinge portion 7 with respect to the container shaft O is referred to as the rear, and the side away from the hinge portion 7 with respect to the container shaft O is referred to as the front.

As shown in FIGS. 3 and 4, a guide portion 12 is formed on the bottom portion 11 of the container body 2. Specifically, the guide portion 12 includes a surrounding wall portion 21 and a container detent portion (detent portion) 22.
The surrounding wall portion 21 extends in an arc shape centered on the container axis O in a plan view.
The container detent portion 22 projects inward in the radial direction from the surrounding wall portion 21. A plurality of container detent portions 22 are provided at intervals in the circumferential direction.

A plurality (for example, three) of the guide portions 12 described above are provided at intervals in the circumferential direction. However, the number of guide units 12 can be changed as appropriate. In the guide portion 12, for example, the container detent portion 22 may be formed at intervals in the circumferential direction with respect to the surrounding wall portion 21 formed in an annular shape centered on the container shaft O. Further, the structure may be such that only the container detent portion 22 is formed.

In the bottom portion 11 of the container body 2, a regulation protrusion 14 is formed in a portion located further in front of the guide portion 12 located in front of the container shaft O. The regulation protrusion 14 projects upward from the bottom 11. In the present embodiment, the regulation protrusion 14 is formed in an arc shape centered on the container shaft O. However, as shown in FIG. 3, the regulation protrusion 14 may have a configuration having a first regulation surface 14a facing one side in the circumferential direction and a second regulation surface 14b facing the other side in the circumferential direction. .. That is, the regulation protrusion 14 may have a configuration in which the first regulation surface 14a and the second regulation surface 14b are separately provided.

As shown in FIGS. 3 and 4, a container sliding protrusion (lower end engaging portion) 16 is formed at a portion of the bottom portion 11 located in front of the regulation protrusion 14. The container sliding protrusion 16 bulges upward from the bottom 11. The upper surface of the container sliding protrusion 16 is formed on an inclined surface that extends upward toward the rear. The rear end portion of the container sliding protrusion 16 is connected to the lower end portion of the regulation protrusion 14. In the present embodiment, the length of the container sliding protrusion 16 in the circumferential direction is shorter than the length of the regulation protrusion 14 in the circumferential direction. The upper surface of the regulation protrusion 14 may be a curved surface or a flat surface orthogonal to the container axis O. Further, the container sliding protrusion 16 may be separated from the regulation protrusion 14.

The peripheral wall portion 23 of the container body 2 extends upward from the outer peripheral edge of the bottom portion 11. An engaging space 24 is formed at the front end of the peripheral wall portion 23. The engagement space 24 is open forward and upward. A push piece 25 is held in the engagement space 24. The push piece 25 is supported by the peripheral wall portion 23 so as to be able to move back and forth in the engaging space 24. An engaging protrusion 26 projecting forward is formed in a portion of the peripheral wall portion 23 facing the rear of the engaging space 24.

As shown in FIG. 4, in the peripheral wall portion 23, a container locking claw (vertical regulation portion) 28 protruding inward in the radial direction is formed at the central portion in the vertical direction. The container locking claw 28 extends in the circumferential direction. In the present embodiment, the container locking claws 28 are formed between the adjacent guide portions 12, respectively. However, the formation range, number, and the like of the container locking claws 28 can be changed as appropriate. For example, the container locking claw 28 may be formed over the entire circumference of the peripheral wall portion 23, or may be formed at the same position as the guide portion 12 in the circumferential direction.

As shown in FIG. 4, the container locking claw 28 is formed in a triangular shape in a cross-sectional view. Specifically, the amount of protrusion of the container locking claw 28 inward in the radial direction gradually increases as it goes downward. The lower surface of the container locking claw 28 is formed on a flat surface orthogonal to the container axis O.

As shown in FIG. 2, the lid 3 is rotatably supported by the rear end portion of the peripheral wall portion 23 via the hinge portion 7 described above. The lid body 3 is formed in a climax cylinder shape. The lid 3 closes the upper end opening of the container body 2 so as to be openable and closable from above the container body 2.
A mirror M is attached to the lower surface of the top wall portion 31 of the lid body 3.
An engaging piece 33 projects downward from the front end portion of the peripheral wall portion 32 of the lid body 3. The engaging piece 33 enters the engaging space 24 from above the container body 2 at the closed position of the lid 3, and engages with the engaging protrusion 26 in the engaging space 24. The engaging piece 33 is disengaged from the engaging protrusion 26 as the push piece 25 moves backward. The push piece 25 is not an essential configuration.

As shown in FIGS. 4 and 5, the rotating member 4 is formed in a tubular shape coaxial with the container shaft O. The rotating member 4 is housed in the container body 2 and is configured to be rotatable around the container shaft O with respect to the container body 2. The rotating member 4 includes an outer cylinder 41, an inner cylinder 42, and an operation unit 43.

The outer cylinder 41 is formed in a tubular shape extending along the inner surface of the peripheral wall portion 23. At the lower end of the outer cylinder 41, an outer cylinder locking claw (upper and lower regulation portion) 45 protruding outward in the radial direction is formed. The outer cylinder locking claw 45 is formed in a triangular shape in a cross-sectional view. Specifically, the amount of protrusion of the outer cylinder locking claw 45 to the outside in the radial direction gradually increases as it goes upward. The upper surface of the outer cylinder locking claw 45 is formed on a flat surface orthogonal to the container axis O. The upper surface of the outer cylinder locking claw 45 is close to or in contact with the lower surface of the container locking claw 28 described above from below. As a result, the upward movement of the rotating member 4 with respect to the container body 2 is restricted.

The outer cylinder locking claw 45 may be formed at a position where at least a part of the outer cylinder locking claw 45 overlaps the container locking claw 28 in a plan view within the rotation range of the rotating member 4. In the illustrated example, the outer cylinder locking claw 45 is formed over the entire circumference of the outer cylinder 41.

The inner cylinder 42 is formed in a tubular shape coaxial with the container shaft O. The inner cylinder 42 is arranged inside the outer cylinder 41 at intervals in the radial direction with respect to the outer cylinder 41. The lower end edge of the inner cylinder 42 is close to or in contact with the bottom portion (upper and lower regulation portion) 11 of the container body 2. As a result, the downward movement of the rotating member 4 with respect to the container body 2 is restricted. A female screw portion 51 (see FIG. 5) is formed on the inner peripheral surface of the inner cylinder 42. In the present embodiment, the female thread portion 51 constitutes a multi-thread thread. However, the number of threads of the female thread portion 51 can be changed as appropriate.

A holding recess 53 that opens inward and upward in the radial direction is formed at the upper end of the inner cylinder 42. The holding recess 53 is formed over the entire circumference of the inner cylinder 42. A holding protrusion 54 that projects inward in the radial direction is formed on the inner peripheral surface of the holding recess 53. The holding protrusion 54 may be formed continuously over the entire circumference of the inner cylinder 42, or may be formed intermittently in the circumferential direction.

A regulation recess 57 that opens outward and downward in the radial direction is formed in a part of the inner cylinder 42 in the circumferential direction (a portion located in the front). The regulation recess 57 extends in the circumferential direction. The above-mentioned regulation protrusion 14 is housed in the regulation recess 57. As shown in FIG. 3, among the inner surfaces of the regulation recess 57, the surface facing the first regulation surface 14a in the circumferential direction constitutes the third regulation surface 57a. On the other hand, of the inner surfaces of the regulation recess 57, the surface facing the second regulation surface 14b in the circumferential direction constitutes the fourth regulation surface 57b.

In the rotating member 4, the first regulation surface 14a and the third regulation surface 57a come into contact with each other in the circumferential direction, so that the rotation of the rotating member 4 to the other side in the circumferential direction with respect to the container body 2 is restricted. The rotating member 4 is restricted from rotating in one side in the circumferential direction with respect to the container body 2 by abutting the second regulating surface 14b and the fourth regulating surface 57b in the circumferential direction (see FIG. 7). That is, the regulating protrusion 14 and the regulating recess 57 form a rotation limiting portion that limits the rotation range of the rotating member 4 with respect to the container body 2.

In the present embodiment, the regulation recesses 57 are formed at positions different by 180 ° in the circumferential direction. As a result, the rotating member 4 can be assembled to the container body 2 in a direction different by 180 ° in the circumferential direction. However, at least one regulation recess 57 may be provided. Further, in the above-described embodiment, the case where the rotation limiting portion is configured by the combination of the regulating protrusion 14 and the regulating recess 57 has been described, but the present invention is not limited to this configuration. The rotation limiting portion may be a combination of the regulating protrusions or the like as long as the rotation range of the rotating member 4 with respect to the container body 2 can be restricted.

Of the outer cylinder 41 described above, the outer cylinder sliding protrusion (lower end engaging portion) 58 is located at a position that faces the regulation recess 57 (regulation recess 57 in which the regulation protrusion 14 is housed) in the radial direction. It is formed. The outer cylinder sliding protrusion 58 is located on one side in the circumferential direction with respect to the center in the circumferential direction of the regulation recess 57. The outer cylinder sliding protrusion 58 projects downward from the outer cylinder 41. The outer cylinder sliding protrusion 58 is pressed against the container sliding protrusion 16 described above from above the container sliding protrusion 16. The container sliding protrusion 16 and the outer cylinder sliding protrusion 58 may be configured to slide with each other in the radial direction.

As shown in FIGS. 4 and 5, the operation unit 43 includes an operation cylinder 61 and a guide cylinder 62.
The operation cylinder 61 projects upward from the outer cylinder 41. The upper end portion of the operation cylinder 61 projects upward from the peripheral wall portion 23 of the container body 2. The upper part of the operation cylinder 61 is formed in a polygonal shape in a plan view. However, the upper portion of the operation cylinder 61 may be formed in a circular shape in a plan view.

The guide cylinder 62 extends upward from the outer peripheral portion of the inner cylinder 42. Specifically, the guide cylinder 62 is formed in a 1/4 arc shape that faces outward and downward in the radial direction in a cross-sectional view. Specifically, the guide cylinder 62 extends outward in the upward radial direction. The upper end of the guide cylinder 62 is connected to the upper end of the operation cylinder 61 described above. Therefore, the width of the operation unit 43 in the radial direction gradually narrows toward the upper side.

As shown in FIG. 5, a finger rest recess 65 is formed in the operation unit 43. The finger rest recess 65 penetrates the operation portion 43 in the radial direction and opens upward. In the present embodiment, the finger rest recesses 65 are formed at positions facing each other in the radial direction. The number of finger rest recesses 65 may be singular or plural. Further, the finger rest recess 65 is not an essential configuration.

The middle plate 5 is detachably attached to the inside of the rotating member 4. Specifically, the middle plate 5 includes a middle plate main body 71, a flange portion 72, and a mounting cylinder 73.
The middle plate main body 71 is formed in a bottomed tubular shape that opens upward. Contents such as cosmetics are stored in the inner plate main body 71. A support protrusion 76 is formed on the outer peripheral portion of the bottom portion 75 of the middle plate main body 71. The support protrusion 76 projects downward from the bottom 75. The support protrusion 76 comes close to or abuts on the bottom 11 of the container body 2 from above the bottom 11 when the middle plate 5 is at the lowermost position (hereinafter referred to as a mounting position).

The peripheral wall portion 78 of the middle plate main body 71 is formed with a middle plate detent portion (detent portion) 81. The middle plate detent portion 81 projects outward from the peripheral wall portion 78 in the radial direction and extends in the vertical direction. A plurality of middle plate detent portions 81 are formed at intervals in the circumferential direction. The middle plate detent portion 81 is close to or in contact with the container detent portion 22 of the guide portion 12 described above in the circumferential direction. The container detent portion 22 and the middle plate detent portion 81 are engaged with each other in the circumferential direction to form a detent portion that regulates the rotation of the middle plate 5 with respect to the container body 2. The number, shape, and the like of the middle plate detent portion 81 can be appropriately changed as long as it is configured to engage with any of the container detent portions 22.

The flange portion 72 projects outward in the radial direction from the upper end portion of the peripheral wall portion 78. The outer peripheral end of the flange portion 72 is housed in the holding recess 53 at the mounting position of the middle plate 5. The outer peripheral end of the flange portion 72 is locked to the holding protrusion 54 in the holding recess 53. At the mounting position of the middle plate 5, it is preferable that the upper surface of the flange portion 72 and the inner peripheral surface of the guide cylinder 62 are smoothly connected to each other. The inner surface of the lid 3, the upper surface of the flange portion 72, and the inner peripheral surface of the guide cylinder 62 define a coating tool accommodating space S for accommodating the coating tool P such as a puff.

The mounting cylinder 73 extends downward from the flange portion 72. The mounting cylinder 73 is arranged at a portion located outside the guide portion 12 in the radial direction and inside the inner cylinder 42 in the radial direction. A male screw portion 85 is formed on the outer peripheral surface of the inner cylinder 42. The male thread portion 85 is formed into a multi-threaded thread. That is, at the mounting position of the middle plate 5, the male screw portion 85 is screwed to the female screw portion 51 described above.

Next, as a method of using the compact container 1 described above, a method of exchanging the middle plate 5 will be described.
When replacing the middle plate 5, the lid 3 is first opened.
Subsequently, the rotating member 4 is rotated. Specifically, the rotating member 4 is rotated with respect to the container body 2 in one side in the circumferential direction (the direction in which the fastening between the rotating member 4 and the inner plate 5 is released). At this time, since the middle plate 5 is engaged with the container detent portion 22 via the middle plate detent portion 81, the rotation of the middle plate 5 with respect to the container body 2 is restricted. Further, the rotating member 4 is restricted from moving in the vertical direction with respect to the container body 2. Therefore, as shown in FIG. 6, when the rotating member 4 rotates with respect to the container body 2, the female screw portion 51 and the male screw portion 85 slide with each other, so that the middle plate 5 with respect to the container body 2 and the rotating member 4 Rise. After the engagement between the holding protrusion 54 and the flange portion 72 is released, the middle plate 5 rises in a state where the rotation is restricted by the detent portions 22, 81.

As shown in FIGS. 6 and 7, when the rotating member 4 is rotated to a position where the second regulation surface 14b and the fourth regulation surface 57b are close to each other or in contact with each other in the circumferential direction, the middle plate 5 is at the uppermost position (hereinafter, hereinafter). , It is called the exchange position.) At the replacement position, the female screw portion 51 and the male screw portion 85 are released from screwing, and the lower end edge of the male screw portion 85 is supported by the upper end edge of the female screw portion 51. As a result, the middle plate 5 is supported by the rotating member 4 with the upper end edge protruding upward from the upper end edge of the inner cylinder 42. In the present embodiment, the upper end edge of the middle plate 5 is located above the upper end edge of the operation unit 43.

At the replacement position, insert a finger between the guide cylinder 62 and the mounting cylinder 73. After that, a finger is hooked on the flange portion 72, and the middle plate 5 is lifted. As a result, the middle plate 5 is removed from the rotating member 4. In order to insert a finger between the guide cylinder 62 and the mounting cylinder 73, it is preferable to insert the finger through the finger rest recess 65. However, a finger may be inserted between the guide cylinder 62 and the mounting cylinder 73 through the gap between the upper end edge of the guide cylinder 62 and the upper end edge of the mounting cylinder 73.

When the new inner plate 5 is attached, the operation opposite to the above-mentioned removal operation is performed. That is, in a state where the rotating member 4 is arranged at a position where the second regulation surface 14b and the fourth regulation surface 57b are close to each other or in contact with each other in the circumferential direction, the middle plate 5 is supported so that the male screw portion 85 is supported by the female screw portion 51. Is set on the rotating member 4. In this state, the rotating member 4 is rotated to the other side in the circumferential direction. Then, as the rotating member 4 rotates, the female screw portion 51 and the male screw portion 85 slide with each other, so that the middle plate 5 descends with respect to the container body 2 and the rotating member 4. After that, the rotating member 4 is rotated to a position where the first regulation surface 14a and the third regulation surface 57a are close to each other or in contact with each other in the circumferential direction to obtain the above-mentioned mounting position.

As described above, in the present embodiment, the middle plate 5 is raised as the rotating member 4 rotates, and the female screw portion 51 and the male screw portion 85 are disengaged when the middle plate 5 is in the replacement position. did.
According to this configuration, the middle plate 5 can be moved from the mounting position to the replacement position only by rotating the rotating member 4. As a result, the workability at the time of replacing the middle plate 5 can be improved as compared with the case where the replacement work is performed by the two operations of the pushing operation and the rotating operation as in the conventional case.
Moreover, in the present embodiment, since the inner plate 5 can be moved to the replacement position without directly touching the inner plate 5, it is possible to suppress an excessive external force from acting on the inner plate 5. In this case, it is possible to suppress an excessive external force from acting on the inner plate 5 during the replacement work, as compared with a configuration in which the inner plate is detachably fitted to the container body, the inner frame, or the like by, for example, undercut fitting. As a result, it is possible to suppress the influence on the contents, especially when the middle plate 5 is attached.

In the present embodiment, the container sliding protrusion 16 and the outer cylinder sliding protrusion 58 are in sliding contact with each other at the mounting position.
According to this configuration, the middle plate 5 can be held by the frictional force between the container sliding protrusion 16 and the outer cylinder sliding protrusion 58. This makes it possible to prevent the middle plate 5 from rattling with respect to the rotating member 4 and the middle plate 5 from suddenly rotating toward the replacement position with respect to the rotating member 4, for example, when the contents are taken out.

In the present embodiment, the container body 2 and the rotating member 4 are configured to include regulatory surfaces 14a, 14b, 57a, 57d that come into contact with each other at the mounting position and the replacement position, respectively.
According to this configuration, the rotation range of the rotating member 4 with respect to the container body 2 is limited between the mounting position and the replacement position. As a result, the amount of operation of the rotating member 4 at the time of replacement can be easily determined, and workability at the time of replacement can be improved. At this time, for example, the moving range of the finger rest recess 65 can be limited to a predetermined range, so that the position of the finger rest recess 65 can be easily specified when the middle plate 5 is replaced. In particular, in the present embodiment, since the finger rest recesses 65 are located on both sides in the left-right direction with respect to the container shaft O, the finger rest recesses 65 and the hinge portion 7 (lid body 3) are located at the mounting position and the replacement position, respectively. It is possible to prevent the finger contact recesses 65 and the engaging protrusions 26 from lining up in the front-rear direction. As a result, it is possible to prevent a finger or the like from coming into contact with the hinge portion 7 (lid body 3) or the engaging protrusion 26 during the replacement work.

In the present embodiment, the rotating member 4 is provided with an operation unit 43 that projects upward from the inner cylinder 42.

In the present embodiment, the female thread portion 51 and the male thread portion 85 are formed into multi-threaded threads.
According to this configuration, the amount of movement of the middle plate 5 with respect to the amount of rotation of the rotating member 4 can be increased as compared with the configuration in which the female screw portion 51 and the male screw portion 85 are formed in a single thread.

[Second Embodiment]
In the rotating member 4 shown in FIG. 8, the female thread portion 51 includes a first thread thread 101 and a second thread thread 102. The first screw thread 101 is formed on the inner peripheral surface of the inner cylinder 42 at intervals in the circumferential direction within a predetermined range in the circumferential direction (hereinafter, referred to as a first region). The second screw thread 102 is formed on the inner peripheral surface of the inner cylinder 42 in a region other than the first region (hereinafter, referred to as a second region) at intervals in the circumferential direction.
The upper end edge of the second thread 102 is located below the upper end edge of the first thread 101. In the present embodiment, the circumferential range of the first region is set wider than the circumferential range of the second region. Specifically, the first region is set to a range larger than 180 ° and smaller than 270 °. However, the circumferential range of the first region and the second region can be changed as appropriate.

In the present embodiment, as shown in FIG. 9, in the process of shifting from the mounting position to the replacement position, after the engagement between the second thread 102 and the male thread portion 85 is disengaged, the first thread 101 and the male thread portion are disengaged. The engagement with 85 is released. That is, since the upper end positions of the first thread 101 and the second thread 102 are different, when the engagement between the first thread 101 and the male thread 85 is disengaged, the middle plate 5 is, for example, due to its own weight or the like. Tilt. Specifically, since the lower end edge of the male screw portion 85 is mainly supported by the upper end edge of the second thread 102, the portion of the middle plate 5 located in the first region rises above the rotating member 4.
As a result, it is possible to easily insert a hand between the middle plate 5 and the rotating member 4, and workability at the time of replacement can be improved.

In the present embodiment, since the finger rest recess 65 as in the first embodiment is not formed, the entire circumference of the middle plate 5 is surrounded by the operation unit 43. As a result, spillage of the contents can be suppressed.
