Description

The present invention relates to compact containers.

2. Description of the Related Art Compact containers are known to have a structure that includes an inner tray in which contents are stored, and a container body in which the inner tray is accommodated through an opening that opens upward. When replacing the inner plate in this type of compact container, for example, the inner plate is pushed up through a through hole formed in the bottom wall of the container body, or the inner plate is pulled up by hooking a nail or the like on the upper edge of the inner plate. etc. was necessary. Therefore, for users of compact containers, it cannot be said that the workability is good.

Therefore, for example, Patent Document 1 listed below discloses a configuration in which an inner plate is supported by a container body via a detachment member. According to this configuration, the engagement between the detachment member and the container body and the engagement between the inner plate and the container body are released by rotating the detachment member with respect to the container body.

Utility model registration No. 2544666

However, in the above-mentioned compact container, since it is necessary to rotate the inner plate, the detachment member, etc. relative to the container body, there is still room for improvement in workability when replacing the inner plate.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a compact container that can improve workability when replacing the inner plate.

In order to solve the above problems, the present invention proposes the following means.
A compact container according to one aspect of the present invention includes an inner tray in which contents are stored, a container body having a peripheral wall portion and a bottom wall portion, and in which the inner tray is housed, and within the container body, an inner frame for holding the inner tray, the inner frame having a frame body vertically movably supported by the container body, a bottom wall portion of the inner tray and a bottom wall portion of the container body; a push-up leg that supports the inner plate and is rotatably connected to the frame body; a downward piece that extends downward from the frame body; and a folded piece extending linearly in a direction away from the downward facing piece and configured to be elastically deformable in a direction approaching and away from the peripheral wall of the inner plate, and formed on the peripheral wall; The middle frame includes an engaging piece that engages with the engaged portion, and a pressing portion formed on a part of the frame body in the circumferential direction, and the middle frame is configured to move between the first position and the downward movement of the frame body. As the push-up leg rotates upward, the inner plate is moved upwardly from the first position to a second position, and the first position of the inner frame is attached to the container body. A guide portion is formed to displace the engaging piece in a direction away from the peripheral wall portion as the engaging piece moves from the position to the second position, and the middle frame is formed between the pressing portion and the peripheral wall portion. The inner frame is movable downward with respect to the container body from the first position to the second position by an amount of the vertical gap created, and the inner frame is configured such that the pressing part abuts the peripheral wall part. As a result, downward movement relative to the container body is restricted with a gap left between the engagement piece and the bottom wall.

According to this aspect, the inner plate can be lifted upward by the pushing operation of the frame body. This makes it possible to improve the work efficiency when replacing the inner plate, compared to the conventional methods of pushing the inner plate from below the container body or pulling up the inner plate directly from above.
Moreover, in this aspect, the push-up legs are arranged between the bottom wall of the inner tray and the bottom wall of the container body to support the inner tray from below, so the inner frame moves from the first position to the second position. In the process of doing so, when the push-up leg rotates upward, interference between the push-up leg and the inner plate in the horizontal plane can be suppressed. Therefore, the push-up leg can be smoothly moved between the first position and the second position.
In addition, since the push-up leg is placed between the bottom wall of the inner tray and the bottom wall of the container body, the push-up leg can absorb loads such as impact force applied to the container body due to, for example, a falling impact of a compact container. It can be absorbed. As a result, the load transmitted to the inner tray can be reduced, so that damage and scattering of the contents accommodated in the inner tray can be suppressed.

Here, in this aspect, the engaging piece is configured to be displaced in a direction away from the peripheral wall portion as the inner frame moves from the first position to the second position.
According to this configuration, as the inner frame moves downward, the engagement piece is displaced to a position where the engagement with the engaged portion can be released. Therefore, in a state where the inner frame has moved to the second position, it becomes easier to remove the inner plate. In this case, for example, compared to a configuration in which the engagement of the inner plate is released only by the push-up force of the push-up legs, it is possible to suppress the inner plate from jumping upward when the engagement is released. In addition, as the inner frame moves downward, the engagement piece is displaced to a position where the engagement with the engaged part can be released, so the amount of engagement between the engagement piece and the engaged part is reduced at the first position. Can be secured. Therefore, in the first position, it is possible to prevent the inner plate from shaking or coming off the inner frame, and to improve the workability when replacing the inner plate.

In the compact container according to the above aspect, the push-up legs are arranged on both sides of the frame body in the circumferential direction with respect to the pressing part, and the engagement pieces are arranged between the push-up legs that are adjacent in the circumferential direction. may be set.
According to this aspect, since the frame body is pushed through the pressing portion, the area around the pressing portion of the frame body becomes easier to move downward. In this case, since the engaging piece is disposed close to the pressing part, the engagement between the engaging piece and the engaged part is easily released during replacement work.
Moreover, since the push-up legs are arranged on both sides of the pressing portion in the circumferential direction, the push-up force of the frame body can be effectively transmitted to the push-up legs.

The compact container according to the above aspect includes a lid rotatably supported by the container main body via a hinge part, and the pressing part is disposed at the same position as the hinge part in the circumferential direction of the frame main body. You can leave it there.
According to this aspect, since the pressing part is arranged at the farthest position from the user during normal use, it is possible to prevent the user from unexpectedly operating the pressing part.

According to the compact container according to the above aspect, workability when replacing the inner plate can be improved.

Further, in a plan view seen from above and below, the direction intersecting the container axis O is called the radial direction, and the direction going around the container axis O is called the circumferential direction. Note that the shape of the compact container 1 in plan view is not limited to a circular shape, but may be a polygonal shape or other shapes.

The container body 2 has a circular shape in plan view, and is formed into a box shape that opens upward. The above-described lid 3 is rotatably connected to a portion of the container body 2 in the circumferential direction via a hinge portion 7 . In the following description, among the radial directions, the direction connecting the container axis O and the hinge portion 7 is referred to as the front-rear direction L1, and the direction orthogonal to the front-rear direction is referred to as the left-right direction L2. Moreover, in the compact container 1, the side approaching the hinge part 7 in the front-rear direction L1 is referred to as the rear, and the side away from the hinge part 7 in the front-rear direction L1 is referred to as the front.

The peripheral wall portion 12 of the container body 2 has an arcuate portion 12a, a front connecting portion 12b, and a rear connecting portion 12c.
Both the inner circumferential surface and the outer circumferential surface of the circular arc portion 12a are formed in a circular arc shape centered on the container axis O in plan view. The arcuate portions 12a face each other in the left-right direction L2 with the container axis O in between.

As shown in FIG. 3, a guide rail 13 is formed in the circumferential center of each arcuate portion 12a. The guide rail 13 projects radially inward from the arc portion 12a and extends in the vertical direction. In the guide rail 13, a first middle frame engaging portion 13a that protrudes radially inward is formed at the center portion in the vertical direction. The first middle frame engaging portion 13a is formed in a triangular shape, a trapezoidal shape, a semicircular shape, etc. when viewed in a vertical cross-section along the vertical direction. Specifically, the amount of radially inward protrusion of the first middle frame engaging portion 13a gradually increases as it goes downward. Note that a plurality of guide rails 13 may be arranged at intervals in the circumferential direction in each arc portion 12a.

As shown in FIGS. 1 and 2, the front connecting portion 12b connects the front ends of each arc portion 12a. On the outer circumferential surface of the front connecting portion 12b, portions located on both sides in the circumferential direction are smoothly connected to the outer circumferential surface of the arcuate portion 12a. Note that the inner circumferential surface of the front connecting portion 12b extends linearly along the left-right direction L2.

In the front connecting portion 12b, an engagement space 14 is formed at the center in the circumferential direction. The engagement space 14 is open forward and upward. A push piece 15 is held in the engagement space 14 . The push piece 15 is supported by the front connecting portion 12b (peripheral wall portion 12) so as to be movable back and forth within the engagement space 14. An engagement protrusion 16 that protrudes forward is formed in a portion of the front connecting portion 12b that faces the rear of the engagement space 14.

The rear connecting portion 12c connects the rear ends of each arc portion 12a. The rear connecting portion 12c includes a front portion 17 that projects forward from the rear end of each arcuate portion 12a, and a horizontal wall portion 18 that connects the front ends of the front portions 17 to each other.
The horizontal wall portion 18 extends linearly along the left-right direction L2 on the inside in the radial direction with respect to the outer circumferential surface of the arcuate portion 12a. The space defined by the front portion 17 and the side wall portion 18 constitutes a hinge space 19 that opens rearward and upward.

As shown in FIGS. 2 and 3, an inner stepped portion 20 is formed at the inner peripheral edge of the upper end of the circular arc portion 12a and the front connecting portion 12b of the peripheral wall portion 12. As shown in FIGS. The inner step portion 20 is open upward and radially inward. In the peripheral wall portion 12, an outer stepped portion 21 is formed at the outer peripheral edge of the upper end of the circular arc portion 12a and the front connecting portion 12b. The outer step portion 21 is open upward and outward in the radial direction.
On the other hand, the upper edge of the rear connecting portion 12c is located below the bottom surface of each stepped portion 20, 21 of the arcuate portion 12a and the front connecting portion 12b.

As shown in FIG. 2, in the front connecting portion 12b, a second middle frame engaging portion 24 is formed at the center in the vertical direction. The second middle frame engaging portion 24 penetrates the front connecting portion 12b in the front-rear direction L1. The second middle frame engagement portion 24 communicates with the engagement space 14 .

As shown in FIGS. 2 and 3, the lid 3 is rotatably supported at the rear end of the peripheral wall 12 via the hinge 7 described above. The lid body 3 is formed in the shape of a capped cylinder. The lid body 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.

The peripheral wall portion 32 of the lid 3 is accommodated within the above-mentioned outer step portion 21 when the lid 3 is in the closed position. As shown in FIG. 2, a rotating piece 35 projects downward from the rear end of the peripheral wall 32. As shown in FIG. The rotating piece 35 is housed within the hinge space 19 described above. A lower end portion of the rotating piece 35 is connected to the front portion 17 of the container body 2 via the hinge portion 7 .
An engaging portion 33 protrudes rearward from the front end of the peripheral wall portion 32 . The engaging portion 33 enters the engaging space 14 from above the container body 2 when the lid 3 is in the closed position. The engaging portion 33 engages with the engaging protrusion 16 within the engaging space 14 . The engagement portion 33 is disengaged from the engagement protrusion 16 as the push piece 15 moves backward as described above. Note that the push piece 15 is not an essential component.

As shown in FIGS. 2 to 4, the inner frame 4 removably holds the inner plate 5 within the container body 2. As shown in FIGS. The middle frame 4 includes a frame body 41, a connecting portion 42, push-up legs 43, and an engagement piece 44.
The frame body 41 is formed into a cylindrical shape that is coaxial with the container axis O when viewed from above. The frame body 41 is held within the container body 2 so as to be vertically movable. In this embodiment, the frame main body 41 has two positions: a first position where the inner plate 5 is held inside the inner frame 4, and a second position where at least a portion is located below the first position and where the inner plate 5 is raised. (the state shown in FIG. 7). The frame body 41 includes an annular wall portion 50, a pressing portion 51, an outer circumferential wall portion 52, and an inner circumferential wall portion 53.

The outer peripheral edge of the annular wall portion 50 is supported by the bottom surface of the inner step portion 20 from below. Therefore, the portion of the annular wall portion 50 located above the arcuate portion 12a and the front connecting portion 12b is restricted from moving downward relative to the container body 2. In addition, in this embodiment, the radius of curvature of the peripheral wall portion 12 of the container body 2 differs depending on the position in the circumferential direction. Therefore, by supporting the outer peripheral edge of the annular wall portion 50 within the inner step portion 20, rotation of the inner frame 4 about the container axis O with respect to the container body 2 is restricted.

The pressing portion 51 extends rearward from the rear end of the annular wall portion 50 . The pressing portion 51 is formed in an elliptical shape with its major axis extending in the left-right direction L2 when viewed from above. The pressing portion 51 overlaps the front portion 17 and the side wall portion 18 described above in a plan view, and covers a part of the hinge space 19 described above from above.

As shown in FIG. 2, the upper surface of the pressing portion 51 has a downwardly protruding arc shape in a longitudinal cross-sectional view. Specifically, the upper surface of the pressing portion 51 extends downward toward the rear. Therefore, the upper surface of the pressing portion 51 is depressed downward relative to the upper surface of the annular wall portion 50.

A gap S is provided between the lower surface of the pressing part 51 and the upper edge of the horizontal wall part 18. The pressing portion 51 (the rear half of the frame body 41) is configured to be movable in the vertical direction by the gap S described above. A protrusion 51b is formed on the lower surface of the pressing portion 51 at a portion located rearward of the horizontal wall portion 18. The protrusion 51b overlaps the upper end of the horizontal wall portion 18 in the radial direction when the frame main body 41 is lowered (see FIG. 8).

As shown in FIG. 4, a slit 51a that opens rearward is formed at the rear end edge of the pressing portion 51. As shown in FIG. In this embodiment, two slits 51a are formed at intervals in the circumferential direction. The above-mentioned rotating piece 35 is housed in the slit 51a.

As shown in FIG. 3, the outer peripheral wall portion 52 extends downward from the outer peripheral portion of the annular wall portion 50. As shown in FIG. That is, the outer circumferential wall portion 52 is formed in a circular arc shape extending around the container axis O and following the inner surface shape of the circular arc portion 12a in plan view.

A guide groove 56 is formed in the outer peripheral wall portion 52 in which the guide rail 13 described above is accommodated. The guide groove 56 is recessed inward in the radial direction and extends in the vertical direction. A first engagement protrusion 54 that protrudes radially outward is formed at the lower end of the inner surface of the guide groove 56 . The first engaging protrusion 54 is formed in a triangular shape, a trapezoidal shape, a semicircular shape, etc. when viewed in a longitudinal section along the vertical direction. Specifically, the amount of radially outward protrusion of the first engagement protrusion 54 gradually increases as it goes upward. The upper surface of the first engaging protrusion 54 engages with the first intermediate frame engaging portion 13a described above from below.

As shown in FIG. 5, the inner peripheral wall portion 53 extends downward from the inner peripheral edge of the annular wall portion 50. As shown in FIG. The inner peripheral wall portion 53 is formed into a cylindrical shape coaxially arranged with the container axis O. Further, as shown in FIG. 2, a second engaging protrusion 55 that protrudes forward is formed in a portion of the inner peripheral wall portion 53 that faces the front connecting portion 12b in the front-rear direction L1. The second engaging protrusion 55 is formed in a triangular shape, a trapezoidal shape, a semicircular shape, etc. when viewed in a vertical cross-section along the vertical direction. Specifically, the amount of forward protrusion of the second engagement protrusion 55 gradually increases as it goes upward. The upper surface of the second engagement protrusion 55 engages within the second middle frame engagement section 24 described above. Note that the outer circumferential wall portion 52 and the inner circumferential wall portion 53 may have different external shapes in plan view.

A first detent portion 57 is formed on the inner circumferential surface of the inner circumferential wall portion 53 . The first detent portion 57 is formed into a protrusion that protrudes inward in the radial direction and extends in the vertical direction.

As shown in FIGS. 4 and 5, a front notch 59 is formed in the front half of the inner peripheral wall 53. As shown in FIGS. In this embodiment, the front notch portion 59 is formed in a portion of the inner circumferential wall portion 53 located on both sides of the engagement space 14 in the circumferential direction. Each front notch 59 is open downward. In this embodiment, the depth of the front notch 59 is equal to the height of the inner peripheral wall 53. The front notch portion 59 divides the inner peripheral wall portion 53 in the circumferential direction. However, the depth of the front notch 59 can be changed as appropriate.

A flexible piece 60 is arranged within each front notch 59 . The flexible piece 60 extends downward in a cantilevered manner from a portion of the inner peripheral edge of the annular wall portion 50 that corresponds to the front notch portion 59 in the circumferential direction. The bending piece 60 is configured to be elastically deformable in the radial direction. A front inner plate engaging portion 61 that protrudes radially inward is formed at the lower end of the flexible piece 60. The front inner plate engaging portion 61 is formed into a triangular shape, a trapezoidal shape, a semicircular shape, etc. when viewed in cross section along the vertical direction. The amount of radially inward protrusion of the front inner plate engaging portion 61 gradually increases as it goes downward. Note that the front inner plate engaging portion 61 does not need to be formed via the flexible piece 60 and may be formed directly on the inner peripheral wall portion 53. In this case, each front notch 59 does not need to be provided.

In the bending piece 60, an inner plate holding part 62 is formed in a portion located below the front inner plate engaging part 61. The inner plate holding portion 62 bulges inward in the radial direction from the flexible piece 60. A radially inner end surface of the inner plate holding portion 62 is formed linearly in the vertical direction in a longitudinal cross-sectional view. The inner plate holding portion 62 approaches or contacts a peripheral wall portion 96 of the inner plate 5, which will be described later, from the outside in the radial direction, and holds the inner plate 5 in the radial direction. Note that the front inner plate engaging portion 61 and the inner plate retainer 62 may be formed on the inner peripheral wall portion 53 itself.

As shown in FIGS. 2 and 4, a rear notch 66 is formed at the rear of the inner circumferential wall 53. As shown in FIGS. The rear notch 66 is open downward. In this embodiment, the depth of the rear notch 66 is equal to the height of the inner peripheral wall 53. The rear notch portion 66 divides the inner peripheral wall portion 53 in the circumferential direction. However, the depth of the rear notch 66 can be changed as appropriate. In this embodiment, the rear notch portion 66 is formed in the inner circumferential wall portion 53 at the same position in the circumferential direction with respect to the hinge space 19 described above.

An inner plate accommodating portion 69 is formed at the boundary between the upper edge of the inner peripheral wall portion 53 and the inner peripheral edge of the annular wall portion 50 . The inner plate accommodating portion 69 is open inward and upward in the radial direction. The inner plate accommodating portion 69 is formed over the entire circumference of the frame body 41. However, the inner plate accommodating portion 69 may be formed in a portion of the frame body 41 in the circumferential direction.

As shown in FIGS. 4 and 5, the connecting portions 42 are formed in the rear half of the inner peripheral wall portion 53 at portions located on both sides of the hinge space 19 in the circumferential direction. In this embodiment, the angle θ formed by the imaginary line Q1 passing through the container axis O and extending along the front-rear direction L1 and the imaginary line Q2 passing through the container axis O and the circumferential center of the connecting portion 42 is, for example, 45° or less. is set to . However, the angle θ can be changed as appropriate. In the illustrated example, a configuration has been described in which the connecting portions 42 are arranged evenly in the circumferential direction with respect to the virtual line Q1, but the configuration is not limited to this. The connecting parts 42 may be arranged unevenly with respect to the virtual line Q1.

Each connecting portion 42 is continuous with the lower edge of the inner peripheral wall portion 53. Specifically, the connecting portion 42 extends radially inward as it goes downward. The maximum thickness of the connecting portion 42 is thinner than the minimum thickness of the inner peripheral wall portion 53. Therefore, the connecting portion 42 can be elastically deformed more easily than the inner peripheral wall portion 53.

The push-up leg 43 is continuous with the radially inner end of the connecting portion 42 . The push-up leg 43 is rotatably connected to the frame body 41 (inner peripheral wall portion 53) with the connecting portion 42 as a starting point. The push-up leg 43 is formed in an L-shape that extends downward and then extends radially inward in a longitudinal cross-sectional view. Specifically, the push-up leg 43 includes a wraparound part 71 and an action part 72.

The wrap-around portion 71 is continuous with the radially inner end of the connecting portion 42 . The wrap-around portion 71 wraps around the corner of the peripheral wall portion 96 and the bottom wall portion 95 of the inner plate 5 (the inner plate main body 91 described later) and reaches below the bottom wall portion 95 . In the illustrated example, the wrap-around portion 71 has a thickness that gradually increases toward the inside in the radial direction.

The action portion 72 is continuous with the radially inner end of the wraparound portion 71 . The action portion 72 extends radially inward along the upper surface of the bottom wall portion 11 of the container body 2 . The lower surface of the action portion 72 is in contact with the upper surface of the bottom wall portion 11 . Therefore, downward rotation of the operating portion 72 with respect to the container body 2 is restricted. Note that the arrangement of the connecting portion 42 and the push-up legs 43 can be changed as appropriate.

In this embodiment, a movement permitting section 70 is formed in the latter half of the above-mentioned arcuate section 12a. The movement permitting portion 70 is formed in a stepped shape that is recessed further downward with respect to the inner step portion 20 described above. The movement permitting portion 70 is formed over a predetermined range in the circumferential direction including the connecting portion 42 from the rear end of each arcuate portion 12a. The bottom surface of the movement permitting portion 70 is connected to, for example, the upper edge of the horizontal wall portion 18 described above. Therefore, in the rear half of the frame body 41, the above-mentioned gap S is continuous in the circumferential direction between the bottom surface of the movement allowing section 70 and the annular wall section 50 and between the pressing section 51 and the horizontal wall section 18. There is.

Since the downward movement of the push-up legs 43 with respect to the container body 2 is restricted, as the frame body 41 and the connection part 42 move downward from the first position to the second position, they rotate from the connection part 42 as a starting point. move. Specifically, the push-up legs 43 rotate upward around the connecting portion 42 while sliding radially inward on the bottom wall portion 11 of the container body 2 . As a result, the push-up leg 43 has an outer circumferential portion (near the wrapping portion 71 ) of the action portion 72 supported on the bottom wall portion 11 of the container body 2 , and an inner circumferential portion thereof supported on the bottom wall portion 11 of the container body 2 . rises from Thereby, the middle frame 4 becomes the second position mentioned above.

As shown in FIGS. 2 and 4, the engagement piece 44 is disposed within the rear notch 66 described above. The engagement piece 44 is formed in a J-shape when viewed in longitudinal section. The engagement piece 44 includes a downward piece 81, a folded piece 82, and a rear inner plate engagement portion 83.
The downward piece 81 extends downward from a portion of the inner peripheral edge of the annular wall portion 50 that corresponds to the rear notch portion 66 in the circumferential direction.

The folded piece 82 extends forward from the lower end edge of the downward piece 81 as it goes upward. The folded piece 82 is configured to be elastically deformable in the front-rear direction L1 (the direction of approaching and separating from the peripheral wall portion 96). The upper edge of the folded piece 82 is located at the center of the downward piece 81 in the vertical direction. Note that the thickness of the folded piece 82 is thinner than the thickness of the downward piece 81.

The rear inner plate engaging portion 83 projects forward from the upper edge of the folded piece 82 . In this embodiment, the rear inner plate engaging portion 83 has a triangular shape, a trapezoidal shape, a semicircular shape, or the like in a longitudinal cross-sectional view. Specifically, both ends of the rear inner plate engaging portion 83 in the vertical direction are curved.

A guide portion 85 is formed in the bottom wall portion 11 of the container body 2 at a position overlapping the folded piece 82 in plan view. The guide portion 85 projects upward from the bottom wall portion 11. In the guide portion 85, the front surface of the folded piece 82 slides as the middle frame 4 moves downward, and the folded piece 82 is elastically deformed rearward. That is, as the inner frame 4 of this embodiment moves downward from the first position to the second position, the push-up legs 43 rotate upward and the folded pieces 82 are displaced rearward. Note that the guide portions 85 may be provided at intervals in the circumferential direction as long as at least a portion thereof is formed at a position overlapping the folded piece 82 in plan view, and a single guide portion may be provided only in a portion of the circumferential direction. may be provided.

As shown in FIGS. 2 and 3, the inner plate 5 is detachably attached to the inner side of the inner frame 4. As shown in FIGS. The inner plate 5 includes an inner plate main body 91 and a flange portion 92.
The inner plate main body 91 is formed into a bottomed cylindrical shape that opens upward. Inside the inner tray main body 91, contents such as cosmetics are stored. The above-mentioned push-up legs 43 are close to or in contact with the outer peripheral portion of the bottom wall portion 95 of the inner plate main body 91 from below. That is, the bottom wall portion 95 is pushed up by the push-up legs 43 as the middle frame 4 moves from the first position to the second position. The inner plate main body 91 is housed in the container main body 2 in a state separated upward from the bottom wall portion 11 of the container main body 2 when the inner frame 4 is in the first position.

The peripheral wall portion 96 of the inner plate main body 91 is formed with an engaged portion 97 that is recessed toward the inside in the radial direction. The engaged portion 97 has a radially inward recess that gradually increases from both sides in the vertical direction toward the center. The engaged portion 97 is formed continuously over the entire circumference of the peripheral wall portion 96 . Of the engaged portions 97, the front region thereof is engaged with the above-mentioned front middle plate engaging portion 61 from above. On the other hand, in the rear region of the engaged portion 97, the aforementioned rear inner plate engaging portion 83 is engaged from above. Thereby, upward movement of the inner plate 5 with respect to the inner frame 4 is restricted. Note that the engaged portions 97 may be provided separately corresponding to the front inner tray engaging portion 61 and the rear inner tray engaging portion 83.

A second detent portion 98 is formed in a portion of the peripheral wall portion 96 located above the engaged portion 97 . The second detent portion 98 is formed into a protrusion that protrudes outward in the radial direction and extends in the vertical direction. The second detent portion 98 is disposed between adjacent first detent portions 57 and engages with the first detent portion 57 in the circumferential direction. Thereby, rotation of the inner plate 5 with respect to the inner frame 4 is restricted. Note that the second detent portions 98 are arranged at intervals of 90° in the circumferential direction on the peripheral wall portion 96. However, the number and layout of the second detent portions 98 can be changed as appropriate.

The flange portion 92 projects radially outward from the upper end of the peripheral wall portion 96 . The flange portion 92 is accommodated within the above-mentioned inner plate accommodating portion 69. At the first position of the middle frame 4, it is preferable that the upper surface of the flange portion 92 and the upper surface of the annular wall portion 50 continue smoothly.

Next, as a method of using the compact container 1 described above, a method of replacing the inner plate 5 will be explained.
When replacing the inner plate 5, the lid body 3 is first placed in the open position.
Subsequently, as shown in FIG. 6, the frame body 41 in the first position is pushed downward. Specifically, a finger is pressed against the pressing portion 51 and the frame body 41 is pushed downward. Then, the rear half of the frame body 41 (the region of the frame body 41 extending from the pressing part 51 to the connecting part 42 in the circumferential direction) moves downward with respect to the container body 2. That is, in this embodiment, since the region other than the rear half of the frame body 41 is supported from below by the inner stepped portion 20 of the container body 2, downward movement with respect to the container body 2 is restricted. Therefore, only the rear half of the frame body 41 moves downward by the gap S mentioned above.

As shown in FIGS. 6 to 8, when the frame body 41 moves downward, the front surface of the folded piece 82 slides on the upper edge of the guide portion 85, so that the folded piece 82 is elastically deformed rearward. Then, the rear inner plate engaging portion 83 retreats backward from the engaged portion 97, and the engaging piece 44 moves from the engaged position to the disengaged position. Note that the disengagement position is a position where the engagement between the engagement piece 44 and the engaged portion 97 can be released, and in this embodiment, the engagement piece 44 (rear inner plate locking portion 83) This means that the amount of engagement (overlapping area in plan view) between and the engaged portion 97 is smaller than the engagement position.

Furthermore, since the push-up legs 43 are restricted from moving downward relative to the container body 2, they rotate upward from the connecting portion 42 as the frame body 41 moves downward. Specifically, the push-up legs 43 rotate upward around the connecting portion 42 while sliding radially inward on the bottom wall portion 11 of the container body 2 . As a result, in the push-up leg 43, the action portion 72 is lifted off the bottom wall portion 11 of the container body 2 while the wrap-around portion 71 is supported on the bottom wall portion 11 of the container body 2.

As shown in FIG. 8, when the push-up leg 43 rotates upward around the connecting portion 42, the rear half of the inner plate 5 (the part supported by the push-up leg 43) rises. That is, in this embodiment, the rear half of the inner plate 5 can be raised as the frame body 41 is pushed downward. Thereafter, the frame body 41 is pushed to a position where the annular wall portion 50 approaches or abuts the horizontal wall portion 18 from above. As a result, the inner frame 4 moves to the second position, and the inner plate 5 becomes ready for removal. That is, the inner plate 5 is supported within the inner frame 4 in a state in which it is tilted forward and downward with the rear half raised. In this case, the rear half of the inner plate 5 is located above the upper surface of the frame body 41 (annular wall portion 50). Note that when the inner frame 4 is in the second position, the front inner plate engaging portion 61 may be engaged with the engaged portion 97 of the inner plate 5.

Note that the timing at which the engagement piece 44 starts moving toward the disengagement position can be changed as appropriate as long as it is before the push-up by the push-up legs 43 is completed. That is, when the push-up leg 43 starts pushing up, the amount of engagement between the rear inner plate engaging portion 83 and the engaged portion 97 must be smaller than the amount of engagement during normal use (first position). Bye. In this case, the rear inner plate engaging portion 83 may be completely retracted from the engaged portion 97 when the push-up leg 43 starts pushing up.

As shown in FIGS. 8 and 9, in this embodiment, when the middle frame 4 is pushed to the second position and the finger is released from the pressing part 51, the frame body 41 rises again due to the restoring force of the folded piece 82. . Specifically, as the folded piece 82 is restored and deformed forward from the lower end of the downward piece 81, the front surface of the folded piece 82 slides on the upper edge of the guide part 85, thereby causing the frame body to The second half of 41 rises. At this time, by maintaining the upwardly rotated state of the push-up legs 43, as the rear half of the frame body 41 rises, the inner plate 5 rises while being supported by the push-up legs 43 from below.

In this state, the inner plate 5 is taken out from the inner frame 4. Specifically, the user grasps the flange portion 92 and the like and pulls up the inner plate 5 diagonally upward to the rear. As a result, the engagement between the inner plate 5 (engaged portion 97) and the front inner plate engaging portion 61 is released, and the inner plate 5 can be removed. Note that the inner plate 5 may be removed in the second position (the state shown in FIG. 8) described above.

When installing a new inner plate 5, first insert the front part of the new inner plate 5 into the inner frame 4 from diagonally rearward, and insert the inner plate 5 into the front inner plate engaging portion 61 of the inner frame 4. The engaged portion 97 is engaged. In this state, push the rear half of the middle plate 5 downward. Then, the push-up leg 43 is pushed downward through the inner plate 5, so that the push-up leg 43 rotates downward from the connecting portion 42 as a starting point. As the push-up leg 43 rotates downward around the connecting portion 42, the inner plate 5 moves downward. Further, as the inner plate 5 moves downward, the rear inner plate engaging portion 83 is engaged within the engaged portion 97 . This completes the replacement work for the inner plate 5.

In addition, when attaching the inner plate 5, the inner plate 5 may be set with the frame body 41 pushed toward the second position, and then the frame body 41 may be set to the first position. In this case, since the inner plate 5 can be set with the engagement piece 44 moved to the disengagement position, the work of setting the inner plate 5 is facilitated.

In this way, in this embodiment, the push-up legs 43 move the inner tray 5 up and down as the frame body 41 moves up and down.
According to this configuration, the inner plate 5 can be lifted upward by the pushing operation of the frame body 41. This makes it possible to improve work efficiency when replacing the middle plate 5, compared to conventional methods such as pushing the middle plate in from below the container body or pulling up the middle plate directly from above.
Moreover, in this embodiment, the push-up legs 43 are disposed between the bottom wall portion 95 of the inner plate 5 and the bottom wall portion 11 of the container body 2, and are configured to support the inner plate 5 from below.
According to this configuration, when the push-up leg 43 rotates upward in the process of moving the middle frame 4 from the first position to the second position, the push-up leg 43 and the inner plate 5 are prevented from interfering in the horizontal plane. It can be suppressed. Therefore, the push-up leg 43 can be smoothly moved between the first position and the second position.
Further, since the push-up leg 43 is disposed between the bottom wall portion 95 of the inner tray 5 and the bottom wall portion 11 of the container body 2, the impact force applied to the container body 2 due to, for example, a falling impact of the compact container 1, etc. The push-up legs 43 can absorb such loads. As a result, the load transmitted to the inner tray 5 can be reduced, so that damage and scattering of the contents accommodated in the inner tray 5 can be suppressed.

Here, in this embodiment, the structure includes the engaging piece 44 that is engaged with and disengaged from the engaged portion 97 of the inner plate 5 as the inner frame 4 moves up and down.
According to this configuration, as the middle frame 4 moves downward, the amount of engagement between the engaging piece 44 and the engaged portion 97 decreases, so that when the middle frame 4 moves to the second position, the middle frame 4 5 becomes easier to remove. In this case, for example, compared to a configuration in which the engagement of the inner plate is released only by the push-up force of the push-up legs, it is possible to suppress the inner plate from jumping upward when the engagement is released. Further, as the middle frame 4 moves downward, the amount of engagement between the engagement piece 44 and the engaged portion 97 decreases, so the amount of engagement between the engagement piece 44 and the engaged portion 97 at the first position. can be secured. Therefore, in the first position, it is possible to prevent the inner plate 5 from shaking or coming off the inner frame 4, and to improve the workability when replacing the inner plate 5.

In this embodiment, the push-up legs 43 are arranged on both sides of the press part 51 in the circumferential direction, and the engagement pieces 44 are arranged between the push-up legs 43 adjacent in the circumferential direction.
According to this configuration, since the frame body 41 is pushed through the press portion 51, the area around the press portion 51 in the frame body 41 becomes easier to move downward. In this case, since the engaging piece 44 is disposed close to the pressing portion 51, the engagement between the engaging piece 44 and the engaged portion 97 is easily released during replacement work.
Furthermore, since the push-up legs 43 are arranged on both sides of the press portion 51 in the circumferential direction, the pushing force of the frame body 41 can be effectively transmitted to the push-up legs 43.

In this embodiment, the pressing part 51 is arranged at the same position as the hinge part 7 in the circumferential direction of the frame main body 41.
According to this configuration, since the pressing part 51 is arranged at the farthest position from the user during normal use, it is possible to prevent the user from unexpectedly operating the pressing part 51.

In this embodiment, the engagement piece 44 includes a downward piece 81 extending downward from the frame body 41, and as it extends upward from the lower end of the downward piece 81, it extends in a direction away from the downward piece 81, and extends downward from the downward piece 81. It includes a folded piece 82 that can be elastically deformed in a direction toward and away from the piece 81, and a rear inner plate engaging part 83 formed at the upper end of the folded piece 82 and engaged with the engaged part 97. The configuration is as follows.
According to this configuration, as the middle frame 4 moves downward, the folded piece 82 is elastically deformed by the guide portion 85 in a direction toward the downward piece 81 . Therefore, as the inner frame 4 moves downward, the rear inner plate engaging portion 83 can be smoothly moved from the engagement position to the disengagement position.
On the other hand, when the pressing force on the pressing part 51 is released, the restoring force of the folded piece 82 acts on the guide part 85, so that the frame main body 41 rises together with the push-up leg 43. Thereby, the amount of protrusion of the inner plate 5 from the opening edge of the container body 2 can be increased compared to when the frame body 41 is in the second position. As a result, work efficiency when replacing the inner plate 5 can be improved.

In the embodiment described above, a configuration has been described in which the inner plate 5 is taken out in a tilted state, but the structure is not limited to this, and a configuration in which the entire inner plate 5 is moved up and down as the frame body 41 moves up and down is also possible.
In the embodiment described above, a configuration has been described in which the engagement between the engagement piece 44 and the engaged portion 97 is completely released at the disengagement position, but the present invention is not limited to this configuration. It is sufficient that the engagement piece 44 engages with the engaged portion 97 less in the disengaged position than in the engaged position.
In the above-described embodiment, a configuration has been described in which at least a portion of the frame body 41 (the annular wall portion 50) is continuous in an annular manner, but the present invention is not limited to this configuration. The frame body 41 may be partially divided in the circumferential direction as long as it surrounds the inner plate 5 .
