[0009] Hereinafter, an embodiment of the compact container according to the present invention will be described with reference to the drawings. In this specification, "up" and "down" refer to the vertical direction when the container body 11 is placed on a horizontal surface (the state in Figure 2). "Rear" refers to the side on which the hinge portion 13 is provided, and "front" refers to the opposite side of "rear". "Left" and "right" refer to the left and right directions when viewed from the front to the rear.

[0010] Figure 1 is a perspective view showing the compact container 10. The compact container 10 is a container for storing solid contents such as pressed powder, which is made by solidifying powdered cosmetics, and application tools such as puffs. The compact container 10 comprises a container body 11 for storing contents and a lid 12 that covers the container body 11. Furthermore, the compact container 10 is provided with a hinge portion 13 that rotatably connects the lid 12 to the container body 11. The lid 12 can be opened and closed by the hinge portion 13. Figure 1 shows the lid 12 in the open position.

[0011] Figure 2 is a cross-sectional view taken along line II-II in Figure 1. Figure 2 shows the lid 12 in the closed position. The container body 11 comprises a bottom lid 15 that forms the outer shell of the container body 11, and a container inner frame 16 that is housed in the bottom lid 15.

[0012] The bottom cover 15 is formed in a substantially rectangular tray shape when viewed from above. The bottom cover 15 comprises a substantially rectangular bottom surface portion 20 and a bottom cover peripheral wall portion 21 erected from the periphery of the bottom surface portion 20. The bottom cover peripheral wall portion 21 comprises a front wall portion 22 erected from the front edge of the bottom surface portion 20, a rear wall portion 23 erected from the rear edge of the bottom surface portion 20, and a pair of left and right side wall portions 24 erected from the left and right edges of the bottom surface portion 20, respectively.

[0013] At the rear end of the bottom cover 15, in the central part on both the left and right sides, there are bottom cover recesses 26 formed by cutting out the rear wall portion 23 and the bottom surface portion 20 toward the front. In a plan view, the central part on both the left and right sides of the rear end of the bottom cover 15 is recessed forward in a roughly rectangular shape by the bottom cover recesses 26.

[0014] In the vicinity of the bottom cover recess 26 at the rear end of the bottom cover 15, a container-side hinge portion 27 is provided. The container-side hinge portion 27 includes a pair of left and right shaft support portions 27a erected from positions on both outer sides of the left and right of the bottom cover recess 26 on the bottom surface portion 20, and a hinge shaft 27b (FIG. 2) supported by the shaft support portions 27a and extending into the bottom cover recess 26. In the cross sections of FIGS. 1 and 2, the left shaft support portion 27a is visible. The hinge shafts 27b extend from the left and right shaft support portions 27a into the bottom cover recess 26 respectively and are provided as a pair. The hinge shafts 27b are shafts extending horizontally in the left and right directions.

[0015] The container middle frame 16 includes a middle frame bottom wall portion 30 arranged to be placed on the bottom surface portion 20 of the bottom cover 15, a middle frame peripheral wall portion 31 erected from the periphery of the middle frame bottom wall portion 30, and a flange portion 32 extending outward from the upper end of the middle frame peripheral wall portion 31 in a plan view. Inside the container middle frame 16, partition walls 30a are provided at the left and right central portions of the middle frame bottom wall portion 30, whereby left and right storage portions 16a, 16b are partitioned. In the left storage portion 16a, a middle dish (not shown) for storing the contents is stored. In the right storage portion 16b, an applicator (not shown) such as a puff is stored.

[0016] The container middle frame 16 is attached to the bottom cover 15 by fitting the middle frame peripheral wall portion 31 inside the bottom cover peripheral wall portion 21 of the bottom cover 15. The flange portion 32 of the container middle frame 16 abuts against the upper end of the bottom cover peripheral wall portion 21 of the bottom cover 15 from above. At the left and right central portions of the rear part of the flange portion 32, rear-side recesses 32a recessed forward along the bottom cover recess 26 of the bottom cover 15 are provided.

[0017] At the left and right central portions of the front part of the flange portion 32, front-side recesses 32b recessed backward are provided. A hook member 33 is disposed between the front surface of the middle frame peripheral wall portion 31 and the front wall portion 22 of the container body 11. The hook member 33 protrudes upward from the front-side recess 32b above the container middle frame 16.

[0018] The lid 12 comprises a lid body 40 that is connected to and rotates on the container side hinge portion 27, an inner frame 41 attached to the lid body 40, and a plate-shaped mirror 42 held by the inner frame 41. Figure 3 is a perspective view showing the lid 12, with the lid 12 open and the inner frame 41 holding the mirror 42 separated from the lid body 40. Figure 4 is a perspective view of the lid body 40 in the state shown in Figure 3. Figure 5 is a perspective view of the inner frame 41 in the state shown in Figure 3. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 2.

[0019] As shown in Figure 2, when the lid 12 is closed, the lid body 40 comprises a top plate portion 44 that covers the container body 11, a peripheral wall portion 45 that extends downward from the peripheral edge of the top plate portion 44, and a lid-side hinge portion 46 that extends downward from the rear end of the top plate portion 44. Note that in Figures 3 to 5, the lid 12 is open and inverted, so the upward direction in Figures 3 to 5 is the downward direction of the compact container 10.

[0020] The top plate 44 is a roughly rectangular plate that conforms to the outer shape of the container body 11 when viewed from above. The peripheral wall portion 45 is a roughly rectangular frame in plan view. More specifically, the peripheral wall portion 45 comprises a front lid wall portion 47 extending downward from the front edge of the top plate portion 44, a rear lid wall portion 48 extending downward from the rear edge of the top plate portion 44, and a pair of left and right lid side wall portions 49 extending downward from the left and right edges of the top plate portion 44, respectively. The lid side wall portions 49 connect the front lid wall portion 47 and the rear lid wall portion 48 front to back.

[0021] A recess 50 that is recessed upward is formed on the lower surface of the lid body 40. The recess 50 is demarcated by the lower surface of the top plate portion 44 and the inner surface of the peripheral wall portion 45. The inner surface of the peripheral wall portion 45 is the inner surface 50a of the recess 50.

[0022] Referring to Figures 2 and 4, the inner circumferential surface 50a of the rear wall portion 48 of the lid is provided with an inner circumferential recess 51 (Figure 2) that recesses toward the outer circumferential side (rear side) of the lid body 40. In addition, the inner circumferential surface 50a of the front wall portion 47 of the lid is provided with an inner circumferential recess 52 that recesses toward the outer circumferential side (front side) of the lid body 40. The inner circumferential recesses 51 and 52 are groove-shaped and extend in the circumferential direction of the inner circumferential surface 50a. The inner circumferential recess 51 is provided in the left and right intermediate parts of the rear wall portion 48 of the lid, and in the upper and lower intermediate parts of the rear wall portion 48 of the lid. The inner circumferential recess 52 is provided in the left and right intermediate parts of the front wall portion 47 of the lid, and in the upper and lower intermediate parts of the front wall portion 47 of the lid.

[0023] Referring to Figure 4, a hook engagement portion 53 is provided below the inner circumferential recess 52 on the inner circumferential surface 50a of the front wall portion 47 of the lid, recessed toward the outer circumferential side (front side) of the lid body 40.

[0024] The lid-side hinge portion 46 is located at the rear end of the top plate portion 44, in the center in the left-right direction. The lid-side hinge portion 46 comprises a shaft-shaped portion 55 extending in the left-right direction along the rear wall portion 48 of the lid, and a shaft hole 56 extending in the left-right direction within the shaft-shaped portion 55. The shaft portion 55 extends in the left-right direction (axial direction of the pivot axis) along the hinge axis 27b, which is the pivot axis of the hinge portion 13. The lid-side hinge portion 46 is provided at the rear end of the top plate portion 44 by connecting the upper rear portion of the axial portion 55, when the lid 12 is closed (Figure 2), to the lower end of the lid rear wall portion 48. Furthermore, the front-to-back width of the axial portion 55 is greater than the thickness of the lid rear wall portion 48. For this reason, the axial portion 55 is positioned in front of and below the lid rear wall portion 48.

[0025] Referring to Figures 2 to 4, the front surface of the lid-side hinge portion 46 has an engagement recess 46a formed in which the left and right intermediate portions of this front surface are recessed toward the rear. Furthermore, the lid-side hinge portion 46 has notches 46b that are cut out from the lower end of the shaft portion 55 upwards in the central left and right portions of the shaft portion 55. The notches 46b penetrate the shaft portion 55 from front to back, and in the portion where the notches 46b are provided, the engaging recesses 46a are also cut out. For this reason, the engaging recesses 46a are located on both the left and right sides of the notches 46b.

[0026] Referring to Figures 1 to 6, the inner frame 41 comprises a substantially rectangular annular frame portion 60 along the inner circumferential surface 50a of the recess 50, a projection 61 extending from the frame portion 60 and engaging with the inner circumferential recess 51, a projection 62 extending from the frame portion 60 and engaging with the inner circumferential recess 52, and a gripping portion 63 extending downward from the rear end of the frame portion 60 when the lid 12 is closed (Figure 2).

[0027] In detail, the frame portion 60 comprises a rear frame edge 65 extending left and right along the rear wall portion 48 of the lid, a front frame edge 66 extending left and right along the front wall portion 47 of the lid, and a pair of left and right side frame edges 67 extending front and rear along each side wall portion 49 of the lid. The side frame edges 67 connect the rear frame edge 65 and the front frame edge 66 front and rear. The rear frame edge 65 and the front frame edge 66 are first frame edges arranged in a pair in the front-to-back direction, facing each other. The left and right side frame edges 67 are second frame edges that connect the rear frame edge 65 and the front frame edge 66. The left and right side frame edges 67 are arranged in pairs in the left-right direction, facing each other.

[0028] A retaining recess 60a (Figure 2) is provided on the inner circumferential surface of the frame portion 60, recessed toward the outer circumferential side of the frame portion 60. The retaining recess 60a is groove-shaped and encircles the inner circumferential surface of the frame portion 60. In plan view, the mirror 42 is a roughly rectangular plate that follows the inner circumferential surface of the frame 60. The mirror 42 is held within the frame 60 by the engagement of its peripheral edge with the retaining recess 60a.

[0029] The gripping portion 63 is a wall-like portion that extends downward from the rear frame edge 65 and engages with the engagement recess 46a of the lid-side hinge portion 46. The gripping portion 63 is provided in the center of the left and right sides of the rear frame edge 65. Refer to Figures 2 to 5 for details. The gripping portion 63 includes a downward extension portion 63a extending forward and downward from the lower end of the rear frame edge 65 along the upper part of the shaft portion 55, a first wall portion 63b extending downward from the lower end of the downward extension portion 63a along the engagement recess 46a, and a second wall portion 63c extending rearward and downward from the lower end of the first wall portion 63b along the engagement recess 46a. The gripping portion 63 has at least a first wall portion 63b and a second wall portion 63c that engage with the engagement recess 46a. As shown in Figure 2, when the gripping portion 63 is engaged with the engaging recess 46a, the lower end of the gripping portion 63 is exposed to the outside through the notch 46b (Figures 3 and 4).

[0030] The projection 61 extends rearward from the rear frame edge 65. A pair of projections 61 are provided, one on the left and one on the right. The projections 61 engage with the inner circumferential recess 51 of the lid body 40, thereby positioning the middle frame 41 vertically relative to the lid body 40. The projection 62 extends forward from the front frame edge 66. A pair of projections 62 are provided, one on the left and one on the right. The projections 62 engage with the inner circumferential recess 52 of the lid body 40, thereby positioning the middle frame 41 vertically relative to the lid body 40.

[0031] The frame portion 60 includes a central frame protrusion 60b, which is formed by bending the side frame edge 67 such that a portion of the longitudinal direction of the side frame edge 67 protrudes toward the container body 11 side (downward side). In the front-rear direction, the central frame protrusion 60b is positioned closer to the lid side hinge portion 46 side. The central frame protrusion 60b is provided on both the left and right side frame edges 67.

[0032] The hinge portion 13 is composed of a lid-side hinge portion 46 and a container-side hinge portion 27. As shown in Figure 2, when the lid 12 is closed, the lid-side hinge portion 46 of the lid body 40 extends downward through the rear recess 32a and is housed in the bottom lid recess 26 of the bottom lid 15. The left and right hinge shafts 27b (Figure 2) are inserted into the shaft holes 56 from both ends of the shaft-shaped portion 55 of the lid-side hinge portion 46, thereby connecting the lid-side hinge portion 46 and the container-side hinge portion 27. The lid 12 is opened and closed by rotating around the hinge shafts 27b via the lid-side hinge portion 46. Referring to Figure 1, when the lid 12 is closed, the hook member 33 engages with the hook engagement portion 53, thereby maintaining the closed position.

[0033] Figure 7 is an enlarged cross-sectional view showing the portion in Figure 6 where the projection 61 and the inner circumferential recess 51 engage. The inner circumferential recess 51 provided in the lid body 40 comprises a recess bottom surface 51a that forms the bottom surface of the inner circumferential recess 51 recessed on the outer circumference side of the lid body 40, a pair of left and right recess side walls 51b that form the widthwise side walls of the inner circumferential recess 51, a recess upper wall 51c that forms the upper wall of the inner circumferential recess 51, and a recess lower wall 51d (Figure 2) that forms the lower wall of the inner circumferential recess 51.

[0034] The bottom surface 51a of the recess extends horizontally parallel to the rear frame edge 65. The recess side wall 51b is an inclined surface that slopes such that the width of the inner circumferential recess 51 decreases as it moves from the inner circumferential surface 50a toward the recess bottom surface 51a. The recess side wall 51b is curved. The upper wall 51c of the recess faces the lower wall 51d of the recess (Figure 2). The projection 61 is sandwiched between the upper wall 51c and the lower wall 51d of the recess.

[0035] The projection 61 comprises an extension 61a that extends from the outer peripheral surface 60c of the frame 60 in the depth direction of the inner peripheral recess 51, and a tip 61b that extends from the extension 61a in the circumferential direction of the middle frame 41. One projection 61 is positioned near the side wall 51b of one recess, and the other projection 61 is positioned near the side wall 51b of the other recess. The pair of projections 61 are arranged such that each tip 61b points toward the central portion 51e in the width direction of the inner circumferential recess 51. The pair of projections 61 are provided symmetrically with respect to the central portion 51e.

[0036] In detail, the extension portion 61a extends in an arc shape toward the central portion 51e as it extends from the outer peripheral surface 60c in the depth direction of the inner peripheral recess 51. The tip portion 61b extends from the tip of the extension portion 61a along the bottom surface 51a of the recess toward the central portion 51e. The end face 61c in the depth direction of the inner circumferential recess 51 at the tip portion 61b is in contact with the bottom surface 51a of the recess. Furthermore, a gap G1 is formed between the tip portion 61b and the outer peripheral surface 60c in the depth direction of the inner circumferential recess 51.

[0037] The recessed side wall 51b covers the projection 61 from the circumferential direction of the central frame 41. The radius of curvature of the curved recessed side wall 51b is larger than the radius of curvature of the arc-shaped extension 61a. The end of the end face 61c on the side of the recessed side wall 51b is located at the boundary 51f between the recessed side wall 51b and the recessed bottom surface 51a. The projection 61 is restricted from moving toward the recessed side wall 51b when the end of the end face 61c on the side of the recessed side wall 51b contacts the boundary 51f. A second gap G2 is provided within the inner circumferential recess 51, which separates the projection 61 and the recess side wall 51b in the circumferential direction of the inner frame 41 (the width direction of the inner circumferential recess 51).

[0038] As the end face 61c of the projection 61 abuts against the bottom surface 51a of the recess, a third gap G3 is formed on the outer circumference of the frame 60, separating the inner circumferential surface 50a from the outer circumferential surface 60c. In the rear frame edge 65, the third gap G3 separates the inner circumferential surface 50a from the outer circumferential surface 60c of the rear frame edge 65 in the front-rear direction. Gap G1 is larger than the third gap G3.

[0039] Referring also to Figure 6, the third gap G3 is also formed in the left and right side frame edges 67. In the side frame edges 67, the third gap G3 causes the inner circumferential surface 50a and the outer circumferential surface 60c of the side frame edges 67 to be separated in the left-right direction.

[0040] Referring to Figure 5, the pair of protrusions 61 are provided on the rear frame edge 65 within the width of the gripping portion 63. As a result, the pair of protrusions 61 are provided in the portion of the rear frame edge 65 where the rigidity is increased by the gripping portion 63.

[0041] Referring to Figure 6, the projection 62 and the inner circumferential recess 52 are basically arranged symmetrically in the front-to-back direction with respect to the projection 61 and the inner circumferential recess 51. However, the inner circumferential recess 52 is formed to be larger in the width direction than the inner circumferential recess 51, and the distance between the left and right projections 62 is also set to be larger in correspondence with the inner circumferential recess 52. In other words, the inner circumferential recess 52, like the inner circumferential recess 51, comprises a recess bottom surface 52a, a pair of left and right recess side walls 52b, a recess upper wall 52c, a recess lower wall 52d (Figure 2), and a boundary portion 52f. Furthermore, the projection 62, like the projection 61, includes an extension 62a, a tip 62b, and an end face 62c.

[0042] A gap G1 is formed between the tip 62b of the projection 62 and the outer circumferential surface 60c in the depth direction of the inner circumferential recess 52. Furthermore, a second gap G2 is provided within the inner circumferential recess 52, which separates the projection 62 and the recess side wall 52b in the circumferential direction of the inner frame 41 (the width direction of the inner circumferential recess 52). Furthermore, as the end face 62c of the projection 62 abuts against the bottom surface 52a of the recess, a third gap G3 is formed on the outer circumference of the frame portion 60. In the portion of the front frame edge 66, the third gap G3 causes the inner circumferential surface 50a and the outer circumferential surface 60c of the portion of the front frame edge 66 to be separated in the front-rear direction.

[0043] As described above, the middle frame 41 holding the mirror 42 is positioned in the vertical, front-back, and left-right directions by the rear projection 61 engaging with the inner circumferential recess 51 and the front projection 62 engaging with the inner circumferential recess 52, and is held on the inner circumferential surface 50a of the lid body 40. In this state, a third gap G3 is formed between the inner circumferential surface 50a and the outer circumferential surface 60c of the frame portion 60. In other words, the inner frame 41 is floatingly supported on the inner circumferential surface 50a of the lid body 40 via projections 61 and 62.

[0044] When the lid 12 is subjected to an impact, such as when the compact container 10 is dropped, the frame portion 60 is displaced to reduce the third gap G3 in the direction of the impact. At this time, the protrusions 61 and 62 elastically deform due to the displacement of the frame portion 60, absorbing the impact and mitigating the impact acting on the mirror 42. When an impact is applied in the front-to-back direction, the protrusions 61 and 62 deform to change the gap G1 and absorb the impact. When an impact is applied in the lateral direction, the projections 61 and 62 deform to change the second gap G2 and absorb the impact. Specifically, with the ends of the projections 61 and 62c on the recess side walls 51b and 52b in contact with the boundary portions 51f and 52f, the projections 61 and 62a deform so that the extensions 61a and 62a mainly bend in the circumferential direction of the central frame 41. Note that the projections 61 and 62c may move slightly beyond the boundary portions 51f and 52f towards the recess side walls 51b and 52b. In this case, as the projections 61 and 62c move beyond the boundary portions 51f and 52f, the depth of the recess side walls 51b and 52b decreases, increasing the resistance to movement towards the recess side walls 51b and 52b, and as the amount of movement increases, the movement of the projections 61 and 62c is restricted. Since the frame portion 60 is positioned on the lid body 40 with a gap G1 and a second gap G2, a large amount of deformation for shock absorption can be secured, and shock can be absorbed effectively.

[0045] Furthermore, as shown in Figure 2, the middle frame 41 holds the mirror 42 while ensuring a fourth gap G4 between the lower surface of the top plate portion 44 and the upper surface of the mirror 42. Therefore, even if an impact is applied in the vertical direction, it is possible to prevent the mirror 42 from coming into contact with the top plate portion 44.

[0046] Figure 8 is a perspective view showing the central frame protrusion 60b. Referring to Figures 1, 2, 5, and 8, the central frame protrusion 60b is a portion of the side frame edge 67 that has been bent in an arc shape so that it protrudes downward. The central frame protrusion 60b protrudes downward relative to the mirror 42. A space K is formed in the vertical direction between the arc-shaped upper surface of the central frame protrusion 60b and the lower surface of the mirror 42. The central frame protrusion 60b does not have a retaining recess 60a (Figure 2) for holding the mirror 42.

[0047] As shown in Figure 2, when the lid 12 is closed, the lower surface of the inner frame protrusion 60b abuts against the upper surface of the container body 11, and the inner frame protrusion 60b receives an upward compressive force from the upper surface of the container body 11 as indicated by arrow A (Figure 8), resulting in an elastically deformed state in the upward direction. Since a space K is provided above the inner frame protrusion 60b, the inner frame protrusion 60b can be easily deformed. Furthermore, when the central frame protrusion 60b is compressed, the portions of the side frame edge 67 located in front of and behind the central frame protrusion 60b are displaced such that the width in front of and behind the central frame protrusion 60b increases.

[0048] When the engagement between the hook member 33 (Figure 1) and the hook engagement portion 53 is released, the central frame protrusion 60b returns to its original position so as to protrude downward, and the lid 12 is automatically flipped upward by the restoring force of the central frame protrusion 60b.

[0049] Here, we will explain an example of the procedure for disassembling the lid 12. The user disassembles the lid 12 when disposing of the compact container 10. The user first opens the lid 12. When disassembling the lid 12, it is opened wider than in Figure 1 (for example, to approximately 180° as shown in Figure 3). As a result, as shown in Figure 2, the lower end of the lid-side hinge portion 46, which was facing downward within the bottom lid recess 26 when the lid 12 was closed, moves to a position where it faces upward from the bottom lid recess 26 as the lid 12 rotates, and becomes exposed upward from the bottom lid recess 26. In this state, the notch portion 46b (Figure 3) and the grip portion 63 are exposed upward from the bottom lid recess 26.

[0050] Next, the user accesses the gripping portion 63 through the notch 46b, grasps the gripping portion 63, and pulls the gripping portion 63 upward and rearward. This releases the engagement of the gripping portion 63 with the engagement recess 46a of the lid hinge portion 46, moves the rear frame edge 65 of the frame portion 60 to the rearward side, and releases the engagement of the projection 61 with the inner circumferential recess 51. Next, the user pulls the frame portion 60 forward via the grip portion 63. This causes the front frame edge 66 of the frame portion 60 to move forward, releasing the engagement of the projection portion 62 with the inner circumferential recess 52. As a result, the mirror 42, along with the inner frame 41, is separated from the lid body 40. After that, the inner frame 41 is removed from the mirror 42.

[0051] As described above, according to an embodiment to which the present invention is applied, the compact container 10 comprises a container body 11, a lid body 40 that is openably connected to the container body 11 via a hinge portion 13, an annular inner frame 41 attached to the inner circumferential surface 50a of a recess 50 provided on the lower surface of the lid body 40, and a mirror 42 held within the frame of the inner frame 41. The inner circumferential surface 50a is provided with inner circumferential recesses 51 and 52 that are recessed into the outer circumferential side of the lid body 40, and the inner frame 41 is provided with projections 61 and 62 that extend from the outer circumferential surface 60c of the inner frame 41 and engage with the inner circumferential recesses 51 and 52 to position the inner frame 41 in the vertical direction. The projections 61 and 62 have tip portions 61b and 62b that extend in the circumferential direction of the inner frame 41 along the bottom surfaces 51a and 52a of the inner circumferential recesses 51 and 52, and a gap G1 is formed between the tip portions 61b and 62b and the outer circumferential surface 60c. In this configuration, the mirror 42 is held within the frame of the inner frame 41, and the inner frame 41 is positioned vertically by projections 61 and 62 extending from the outer peripheral surface 60c of the inner frame 41 engaging with the inner peripheral recesses 51 and 52 of the lid body 40. Therefore, by pulling the inner frame 41 to release the engagement between the projections 61 and 62 and the inner peripheral recesses 51 and 52, the mirror 42 can be separated from the lid body 40 together with the inner frame 41, and the mirror 42 and the lid body 40 can be easily separated. In addition, the tips 61b and 62b of the projections 61 and 62 extend in the circumferential direction of the inner frame 41 along the bottom surfaces 51a and 52a of the recesses, and a gap G1 is formed between the tips 61b and 62b and the outer peripheral surface 60c. As a result, when the tips 61b and 62b come into contact with the bottom surfaces 51a and 52a of the recesses due to impact, the projections 61 and 62 can deform toward the G1 side. Therefore, external impacts can be absorbed by the deformation of the protrusions 61 and 62, effectively protecting the mirror 42 from impact.

[0052] Furthermore, the middle frame 41 is formed in an annular shape and comprises a pair of first frame edges, namely the rear frame edge 65 and the front frame edge 66, which face each other, and a pair of second frame edges, namely the side frame edges 67, which connect the pair of first frame edges. The protrusions 61 and 62 are provided on the pair of rear frame edges 65 and the front frame edge 66. In this configuration, the middle frame 41 is supported by the lid body 40 via projections 61, 62 and inner circumferential recesses 51, 52, through a pair of opposing rear frame edges 65 and front frame edges 66. Therefore, the middle frame 41 can be firmly supported by the lid body 40. As a result, the mirror 42 can be firmly supported through the middle frame 41. Furthermore, since both the impact acting on the rear frame edge 65 and the impact acting on the front frame edge 66 can be absorbed by the projections 61, 62, impact can be absorbed effectively.

[0053] Furthermore, the hinge portion 13 is provided at the rear of the lid body 40, the rear frame edge 65 and the front frame edge 66 are arranged in pairs in the front-rear direction of the lid body 40, and the middle frame 41 has a gripping portion 63 that extends from the rear frame edge 65 toward the container body 11 and engages with the hinge portion 13. With this configuration, the middle frame 41 can be fixed to the lid body 40 by the gripping portion 63 that engages with the hinge portion 13. Furthermore, when separating the mirror 42, pulling the gripping portion 63 releases the engagement of the gripping portion 63 with the hinge portion 13, releases the engagement between the projection 61 on the rear frame edge 65 and the inner circumferential recess 51, and further pulling the gripping portion 63 releases the engagement between the projection 62 on the front frame edge 66 and the inner circumferential recess 52. As a result, the middle frame 41 can be easily separated from the lid body 40, and the mirror 42 and the lid body 40 can be easily separated.

[0054] Furthermore, a protruding portion 60b of the inner frame is provided, which is formed by bending the inner frame 41 so that a part of the inner frame 41 protrudes toward the container body 11. When the lid body 40 is closed, the protruding portion 60b of the inner frame is compressed toward the container body 11. With this configuration, when opening the lid body 40, the restoring force of the central frame protrusion 60b, which is compressed by the container body 11, allows the lid body 40 to be easily opened.

[0055] Furthermore, the middle frame 41 is formed in an annular shape with a pair of opposing rear frame edges 65 and front frame edges 66, and a pair of side frame edges 67 connecting the pair of rear frame edges 65 and front frame edges 66. The projections 61 and 62 are provided on the pair of rear frame edges 65 and front frame edges 66, and the middle frame protrusion 60b is provided on the side frame edge 67. With this configuration, by providing the central frame protrusion 60b on the side frame edge 67, it is possible to suppress the impact absorption by the protrusions 61 and 62 on the rear frame edge 65 and front frame edge 66 due to the compressed side frame edge 67. As a result, the protrusions 61 and 62 can effectively absorb impact, and the restoring force of the central frame protrusion 60b allows the lid body 40 to be opened easily.

[0056] Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiments, and unless otherwise specifically limited in the above description, various modifications and changes are possible within the scope of the spirit of the present invention as described in the claims. For example, the configurations of the embodiments described above can be added or deleted as appropriate, and the configuration of one embodiment can be provided in other embodiments. Furthermore, the effects in the embodiments described above are merely illustrative of the effects that may arise from the present invention, and do not mean that the effects of the present invention are limited to the effects described above. In the above embodiment, it was described that a third gap G3 is formed on the outer circumference of the frame portion 60, separating the inner circumferential surface 50a and the outer circumferential surface 60c. However, the present invention is not limited to this. For example, even if the third gap G3 is not provided and the inner circumferential surface 50a and the outer circumferential surface 60c are in contact, the impact can be absorbed by the deformation of the protrusions 61 and 62 in response to the impact. Furthermore, although the above embodiment described the projections 61 and 62 as being provided on the rear frame edge 65 and the front frame edge 66, the present invention is not limited thereto. For example, projections may be provided on the side frame edge 67, and inner circumferential recesses that engage with these projections may be provided on the inner circumferential surface 50a. Furthermore, although the projection 61 has been described as comprising an extension portion 61a and a tip portion 61b, the present invention is not limited thereto. The projection 61 may have other shapes as long as a gap G is formed between the tip portion, which extends circumferentially along the bottom surface 51a of the recess and the inner frame 41, and the outer surface 60c. For example, the projection 61 may be a straight line extending diagonally from the outer surface 60c in the depth direction of the inner circumferential recess 51 and in the circumferential direction of the inner frame 41, with a gap G formed between the tip portion of this projection 61 and the outer surface 60c. Another shape of the projection 61 may be a projection 61 comprising a pair of left and right extension portions extending from the outer surface 60c in the depth direction of the inner circumferential recess 51, and a tip portion connecting the ends of the pair of extension portions in the circumferential direction of the inner frame 41, with a gap G formed between this tip portion and the outer surface 60c.

[0057] Furthermore, although the projections 61 and 62 have been described as being in contact with the bottom surfaces 51a and 52a of the recesses, the present invention is not limited to this. For example, the projections 61 and 62 may be slightly spaced apart from the bottom surfaces 51a and 52a of the recesses under normal conditions, and may come into contact with the bottom surfaces 51a and 52a when an impact is applied. Furthermore, although the above embodiment was described as maintaining the lid 12 in a closed state by the hook member 33 and the hook engagement portion 53, the present invention is not limited to this. For example, a container-side magnet may be provided instead of the hook member 33, and a lid-side magnet may be provided instead of the hook engagement portion 53, and the lid 12 may be maintained in a closed state by magnetic force. In this case, the lid-side magnet can be sandwiched and positioned between the inner frame 41 and the lid body 40. With this configuration, when the inner frame 41 is removed from the lid body 40, the lid-side magnet can also be separated, and the lid-side magnet can be easily separated. [Explanation of Symbols]
