Note that arrows UP, FR, and RH shown as appropriate in the drawings respectively show the upper side, front side, and right side (one side in the width direction) of the storage box 10. In the following description, when the vertical, front-back, and left-right directions are described, the vertical, front-back, and left-right directions of the storage box 10 are described unless otherwise specified.

(regarding the integral structure of the storage box)

As shown in fig. 1, the storage box 10 is formed in a hollow substantially rectangular parallelepiped box shape. The storage box 10 includes: a box body 20 constituting a main body of the storage box 10; a top plate 40 constituting an upper end portion of the storage box 10; a frame member 50 constituting a front end portion of the storage box 10; and an opening/closing panel 60 openably/closably attached to the frame member 50. The top plate 40 and the frame member 50 are detachably attached to the box main body 20.

As shown in fig. 2, the containers 10 are stacked one on top of another so that the containers 10 can be stacked (fig. 2 shows an example in which the containers 10 are stacked in 2 layers). Further, as shown in fig. 3, in a state where the storage box 10 is disassembled, the box main bodies 20 are configured to be nestable such that the box main bodies 20 are stacked one on top of another (fig. 3 shows an example in which the box main bodies 20 are nested in 3 stages). In the state where the storage box 10 is disassembled, the frame member 50 to which the opening and closing panel 60 is attached is held by the top plate 40, and the top plates 40 in this state can be stacked up and down. This structure is configured as follows: the top plate 40 that holds the frame member 50 and the opening/closing panel 60 can be stacked on the upper side of the nested box main bodies 20 in a wrapped state of the storage box 10. The following describes each configuration of the storage box 10.

(about box main body)

As shown in fig. 4 to 8, the box main body 20 is made of a resin material and is formed in a substantially rectangular parallelepiped box shape open to the upper side and the front side. Specifically, the box main body 20 includes: a substantially rectangular plate-shaped bottom wall 21 having a plate thickness direction in the vertical direction and a longitudinal direction in the front-rear direction; a pair of left and right side walls 22 extending upward from both ends in the width direction of the bottom wall 21; and a rear wall 23 extending upward from a rear end of the bottom wall 21. The inside of the box main body 20 is configured as a storage portion 24 for storing a storage object.

The side wall 22 is inclined outward in the width direction of the box main body 20 upward in front view. The rear wall 23 is inclined rearward as it goes upward in side view. Thus, in the disassembled state of the storage box 10, the box main bodies 20 are arranged inside the other box main bodies 20, and the box main bodies 20 are nested.

A narrowed portion 21A is formed in the bottom wall 21 at a portion other than the left and right outer peripheral portions and the rear outer peripheral portion so as to rise one step upward. The narrow portion 21A is formed in a substantially rectangular shape whose longitudinal direction is the front-rear direction in a plan view. The left and right ends of the front end of the narrowed portion 21A extend outward in the width direction of the box body 20 and are connected to the lower ends of the side walls 22. At the boundary portions between the bottom wall 21 and the left and right side walls of the narrowed portion 21A, side step portions 21B (see fig. 5) are formed which are bent in a substantially crank shape and which rise one step above the bottom wall 21, and the side step portions 21B extend in the front-rear direction. Further, a rear step portion 21C (see fig. 4) bent in a crank shape and rising one step above the bottom wall 21 is formed at a boundary portion between the rear wall 23 and the bottom wall 21, and the rear step portion 21C extends in the left-right direction.

A tank-side mounting portion 25 for mounting a frame member 50 described later is formed at the front end portion of the tank main body 20. The tank-side mounting portion 25 has: a pair of left and right side flanges 25A which are bent outward in the width direction of the box body 20 at the front end portions of the side walls 22; and a lower flange portion 25B bent downward at the tip end portion of the narrower portion 21A. The left and right ends of the lower flange portion 25B are connected to the lower end of the side flange portion 25A. The outer peripheral portion of the tank-side mounting portion 25 is configured as a mounting wall portion 25C, and the mounting wall portion 25C is bent forward at the tip end portions of the side flange portion 25A and the lower flange portion 25B. The lower mounting wall portion 25C is disposed above the bottom wall 21.

A rail step portion 22A bent substantially in a crank shape outward in the width direction of the box body 20 is formed at an upper end side portion of the side wall 22. Specifically, the track step portion 22A includes: a first step wall 22a1 that is bent outward in the width direction of the box main body 20 at the upper end side portion of the side wall 22; and a second step wall 22a2 that is bent upward at the tip end portion of the first step wall 22a 1. The front end of the first stepped wall 22a1 is connected to the upper end of the side flange 25A, and the front end of the second stepped wall 22a2 is connected to the upper ends of the left and right mounting wall portions 25C.

A stopper 26 protruding upward is formed at an intermediate portion in the front-rear direction of the first stepped wall 22a 1. Further, at the end portion of the first stepped wall 22a1 on the widthwise center side of the box main body 20, a rail wall 27 extending upward is formed. The rail wall 27 extends rearward from the front end of the first stepped wall 22a1 in the plate thickness direction in the left-right direction, and is connected to the stopper 26. The rail portion 28 is formed by the rail wall 27, the first step wall 22a1, and the second step wall 22a2, and the rail portion 28 is formed in a groove shape that is open to the upper side and the front side and extends in the front-rear direction.

A fitting rib 30 (broadly, an element understood as a "fitting portion") and a fitted portion 31 used when the box main bodies 20 are fitted to each other are provided at a lower end portion of the side wall 22 of the box main body 20. The fitting rib 30 and the fitted portion 31 are paired, and the paired fitting rib 30 and the fitted portion 31 are formed at 4 positions in the box main body 20. Specifically, the paired fitting ribs 30 and the fitted portions 31 are formed at the front end portion (2) and the rear end portion (2) of the lower end portions of the left and right side walls 22, respectively.

As shown in fig. 8 (a), the fitting rib 30 protrudes inward in the width direction of the box main body 20 from the lower end portion of the side wall 22. Further, the 2-position fitting rib 30 disposed at the rear end portion of the side wall 22 extends upward from the bottom wall 21, and the 2-position fitting rib 30 disposed at the front end portion of the side wall 22 extends upward from the narrowed portion 21A of the bottom wall 21. The upper end surfaces of the 4 fitting ribs 30 are aligned in the vertical direction. That is, the length in the vertical direction of the 2-position fitting rib 30 disposed on the rear side is set longer than the length in the vertical direction of the 2-position fitting rib 30 disposed on the front side, and the upper end portion of the 4-position fitting rib 30 is disposed above the narrowed portion 21A. Further, the upper end surface of the fitting rib 30 is inclined upward toward the inside in the width direction of the box main body 20 as viewed from the front, and the corner portion of the fitting rib 30 is curved in a substantially arc shape.

As shown in fig. 7, the fitted portion 31 is disposed close to the rear side of the fitting rib 30. The fitted portion 31 protrudes inward in the width direction of the box main body 20 from the side wall 22 and protrudes upward from the bottom wall 21. As shown in fig. 8 (B), a fitting groove portion 31A is formed in the fitted portion 31, and the fitting groove portion 31A is open to the outside and the lower side in the width direction of the box main body 20. That is, the fitting groove 31A is exposed to the outside at a lower corner of the box main body 20 (the storage box 10).

The upper end surface of the fitting groove portion 31A corresponds to the upper end surface of the fitting rib 30, and is inclined upward toward the inside in the width direction of the box main body 20. Further, the upper corner of the fitting groove portion 31A corresponds to the corner of the fitting rib 30 and is curved in an arc shape. The upper corner of the fitting groove 31A may have an acute angle instead of an arc shape. Further, the width of the fitting groove portion 31A is set to be slightly larger than the thickness dimension (the dimension in the front-rear direction) of the fitting rib 30, and the depth dimension of the fitting groove portion 31A in the vertical direction is set to be smaller than the height dimension of the fitting rib 30 in the vertical direction. The thickness of the fitting rib 30 is set to be smaller toward the upper side. That is, the side surfaces of the fitting rib 30 are slightly inclined so as to approach each other toward the upper side.

As shown in fig. 8 (C), the following structure is provided: in a state where the box main bodies 20 are nested with each other, the upper end portion of the fitting rib 30 in the lower (one) box main body 20 is inserted into the fitting groove portion 31A in the upper (the other) box main body 20, and the upper end surface of the fitting rib 30 abuts against the upper end surface of the fitting groove portion 31A. Thus, when the tank main bodies 20 are fitted to each other, the upper tank main body 20 is disposed so as to be supported from below by the fitting rib 30 of the lower tank main body 20 and separated from the lower tank main body 20 at the upper side. In this state, the fitting rib 30 abuts against the inner circumferential surface of the fitting groove portion 31A, and thereby the relative displacement of the upper tank main body 20 with respect to the lower tank main body 20 in the front-rear direction is suppressed.

(related to the roof)

As shown in fig. 4, 5, 9, and 10, the top plate 40 is made of a resin material, and is formed in a substantially rectangular box shape having a shallow bottom and opened to the lower side. Specifically, the top plate 40 includes: a top plate body 41 having a substantially rectangular plate shape whose vertical direction is a plate thickness direction and longitudinal direction is a front-rear direction; and a top plate peripheral wall portion 42 that is bent downward at the outer peripheral edge portion of the top plate body 41. A top plate groove portion 41A that opens upward is formed in the outer peripheral portion of the top plate main body 41, and the top plate groove portion 41A extends in the circumferential direction of the top plate 40 and is formed in a rectangular ring shape in a plan view.

A plurality of attachment pieces 43 are formed on the lower surface of the top plate 40 at positions between the left and right top plate peripheral wall portions 42 and the top plate groove portion 41A and the rear top plate peripheral wall portion 42. The attachment pieces 43 are arranged with the circumferential direction of the ceiling groove portion 41A as the plate thickness direction, and are arranged at a predetermined interval in the circumferential direction of the ceiling groove portion 41A. The attachment piece 43 is disposed inside the top plate 40 apart from the top plate peripheral wall portion 42. The upper ends of the side walls 22 and the upper end of the rear wall 23 of the box main body 20 are inserted between the top plate peripheral wall portion 42 of the top plate 40 and the attachment piece 43, and the top plate 40 is attached to the box main body 20.

Further, an outer peripheral portion of a central portion (a portion surrounded by the top plate groove portion 41A) of the top plate body 41 is configured as a ground portion 41B, and the ground portion 41B slightly rises upward with respect to the top plate body 41. In the stacked state of the storage boxes 10, the side step 21B of the upper box body 20 is grounded to the grounding portion 41B of the lower top plate 40, and the center portion of the lower top plate 40 is fitted into the left and right side steps 21B (see the box body 20 shown by the two-dot chain line in fig. 5). This suppresses the shift of the storage boxes 10 in the left-right direction when the storage boxes 10 are stacked. In the stacked state of the storage cases 10, the rear step portion 21C of the upper case body 20 is grounded on the upper surface of the rear end portion of the lower top plate 40, and the rear end side bottom wall 21 of the upper case body 20 is inserted into the inner peripheral portion of the top plate groove portion 41A of the lower top plate 40 (see the case body 20 shown by the two-dot chain line in fig. 4). This suppresses the shift of the upper container 10 to the front side with respect to the lower container 10 when the containers 10 are stacked.

A pair of left and right first fitting pieces 44 (see fig. 9) are formed on the lower surfaces of the left and right top plate groove portions 41A at the front-rear direction intermediate portion and the rear side portion, respectively. That is, the top plate body 41 is formed with 4 first fitting pieces 44. The first fitting piece 44 extends in the front-rear direction with the left-right direction as the plate thickness direction, and protrudes downward from the top plate groove portion 41A. A pair of left and right second fitting pieces 45 is formed on the lower surface of the rear roof groove portion 41A. The second fitting piece 45 extends in the left-right direction with the front-rear direction as the plate thickness direction, and protrudes downward from the top plate groove portion 41A. When the top boards 40 are stacked one on top of another in a wrapped state of the storage box 10, the first fitting piece 44 and the second fitting piece 45 of the upper top board 40 are inserted into the outer peripheral portion of the top board groove portion 41A of the lower top board 40. This structure is configured as follows: in a state where the top boards 40 are stacked up and down, the movement of the upper top board 40 in the left-right direction and the rear side is restricted by the first fitting piece 44 and the second fitting piece 45.

A pair of left and right holding portions 46 (see fig. 9) are formed on the lower surface of the center portion (the portion surrounded by the top plate groove portion 41A) of the top plate main body 41, at the front-rear direction intermediate portion and the rear side portion. That is, the top plate body 41 is formed with 4 holding portions 46. The holding portion 46 is formed in a substantially rectangular plate shape with the left-right direction being the plate thickness direction. A holding hook 46A is formed at the lower end of the holding portion 46, and the holding hook 46A protrudes from the holding portion 46 toward the widthwise center side of the top panel 40. The holding portion 46 is disposed in accordance with the outer shape of a frame member 50 described later.

The front end of the top plate 40 is configured as a top plate side mounting portion 47 for mounting a frame member 50 described later. The ceiling plate side mounting portion 47 is formed in a shape that is lower by one step than the upper surface of the ceiling plate main body 41 and the left and right side surfaces of the ceiling plate peripheral wall portion 42.

(about frame member)

As shown in fig. 4 and 11, the frame member 50 is made of a resin material, and is formed in a rectangular frame shape when viewed from the front and is formed in a concave shape that is open to the rear side. Specifically, the frame member 50 includes: a frame main body 51 formed in a rectangular frame plate shape having a plate thickness direction in a front-rear direction; a frame outer peripheral wall 52 that is bent rearward at an outer peripheral edge of the frame main body 51; and a frame inner peripheral wall 53 that is curved rearward at the inner peripheral edge portion of the frame main body 51. The tank-side mounting portion 25 of the tank main body 20 and the ceiling-side mounting portion 47 of the ceiling 40 are fitted between the outer peripheral wall 52 and the inner peripheral wall 53 of the frame member 50, and the frame member 50 is mounted to the tank main body 20 and the ceiling 40. Thus, when the storage boxes 10 are stacked vertically, the rectangular frame members 50 are arranged vertically, and the front appearance of the storage boxes 10 in the stacked state is rectangular (see fig. 2). When the storage boxes 10 are arranged in a left-right array, the side surfaces of the frame members 50 arranged in the left-right array are brought into close contact with each other, so that the storage boxes 10 can be arranged.

As shown in fig. 12 and 13, a recessed hinge receiving portion 54 that opens to the rear side is formed at the top end portion (rear end portion) of the frame inner peripheral wall 53 at the positions of both upper corners. The hinge housing portion 54 is disposed on the front side of the rail portion 28 (specifically, the rail wall 27) of the box main body 20. Further, on the frame inner peripheral wall 53, a protruding portion 55 protruding toward the inside of the frame member 50 is formed in a portion other than the upper frame inner peripheral wall 53 and the hinge receiving portion 54. The protruding portion 55 extends in the circumferential direction of the frame inner peripheral wall 53, and is formed in a substantially U-shape that is open to the upper side when viewed from the front. Thus, an opening 56 formed by the upper end portion of the frame inner peripheral wall 53 and the extension portion 55 is formed in the frame member 50.

The extension portion 55 is formed in a substantially L-shape when viewed in the longitudinal direction. Specifically, the protruding portion 55 includes: a first projecting wall 55A that extends from a tip end portion (rear end portion) of the frame inner peripheral wall 53 toward the inside of the frame member 50; and a second projecting wall 55B extending rearward from a tip end portion of the first projecting wall 55A. Further, support walls 57 are formed at both ends of the extension portion 55 in the longitudinal direction, and the support walls 57 are disposed with the vertical direction being the plate thickness direction, and are connected to the extension portion 55 and the frame inner peripheral wall 53. In addition, the position of the upper surface of the support wall 57 in the vertical direction substantially coincides with the position of the upper surface of the rail wall 27 of the box main body 20. Further, the space above the support wall 57 is configured as a frame-side insertion portion 58, and the frame-side insertion portion 58 communicates with the hinge housing portion 54 and the opening portion 56. That is, the lower portion of the frame-side insertion portion 58 is constituted by the support wall 57.

A recessed handle recess 50A that opens upward and forward is formed in the lower end portion of the frame member 50 at the center in the left-right direction. Further, a hook 59 is formed at the center portion in the left-right direction of the lower second projecting wall 55B, and the hook 59 projects upward from the second projecting wall 55B and extends in the left-right direction.

In the case of a bundle pack form of the storage box 10, the frame member 50 is disposed in the region surrounded by the roof groove 41A on the lower side of the roof 40, and is held by the holding portion 46. Specifically, the holding hook portion 46A of the holding portion 46 of the top plate 40 engages with the outer peripheral portion of the frame member 50, and the frame member 50 is held by the top plate 40. In a state where the frame member 50 is held by the top plate 40, the thickness of the frame member 50 is set to be equal to or less than the depth of the top plate groove 41A so that the frame member 50 does not protrude from the top plate groove 41A.

(about opening and closing panel)

As shown in fig. 14, the opening/closing panel 60 is made of a resin material and is formed in a substantially rectangular plate shape having a plate thickness direction in the front-rear direction and a longitudinal direction in the left-right direction. The opening/closing panel 60 is disposed inside the frame inner peripheral wall 53 of the frame member 50 and on the front side of the extension portion 55 of the frame member 50 (at a position shown in fig. 1, hereinafter, the position of the opening/closing panel 60 is referred to as a "closed position"). Thereby, the opening 56 of the frame member 50 is closed by the opening/closing panel 60 at the closing position. The dimension of the opening/closing panel 60 in the width direction is set to be slightly smaller than the distance between the left and right frame inner peripheral walls 53 in the frame member 50. Thereby, at the closing position of the opening/closing panel 60, the lateral shaking of the opening/closing panel 60 with respect to the frame member 50 is suppressed.

As will be described in detail later, the opening/closing panel 60 is rotated from the closing position to the front rotational position (the position shown in fig. 15A) by the opening/closing operation of the user, and is disposed in the storage position (the position shown in fig. 15B) which is slid from the rotational position to the rear side. Specifically, at the rotational position of the opening/closing panel 60, the opening/closing panel 60 is disposed in a horizontal state. Then, by sliding the opening/closing panel 60 in the horizontal state to the rear side, the opening/closing panel 60 is disposed at the storage position where most of the opening/closing panel 60 is disposed inside the box main body 20.

A panel outer peripheral wall 61 extending rearward is integrally formed at an outer peripheral edge of the opening/closing panel 60, and the panel outer peripheral wall 61 is formed over the entire periphery of the opening/closing panel 60. Specifically, the panel outer peripheral wall 61 includes: panel side walls 61A extending rearward from both ends in the width direction of the opening/closing panel 60; a panel upper wall 61B extending rearward from an upper end of the opening/closing panel 60; and a panel lower wall 61C extending rearward from a lower end of the opening/closing panel 60. Thus, both widthwise side portions of the opening/closing panel 60 constitute panel side walls 61A. The panel side wall 61A has a thickness T1 in the front-rear direction that increases from the top to the bottom. Specifically, in a side view, the front end surface (rear end surface) of the panel side wall 61A is inclined rearward as going downward. That is, in the horizontal state of the opening/closing panel 60 at the rotational position, the front end surface of the panel side wall 61A is set to be inclined downward toward the front side.

Further, a pair of left and right hinge pieces 62 are formed at the upper end portions of the left and right panel side walls 61A and at the rear end portion of the panel side wall 61A, and the hinge pieces 62 protrude outward in the width direction of the opening and closing panel 60 from the panel side wall 61A with the front-rear direction being the plate thickness direction. Further, the tip end portion of the hinge piece 62 is bent rearward. The proximal end portion of the hinge piece 62 is disposed inside the hinge housing portion 54 and the frame-side insertion portion 58 of the frame member 50 (see fig. 12). Thus, the lower end of the hinge piece 62 is supported by the lower end of the hinge receiving portion 54 of the frame member 50, and the forward movement of the upper end of the opening/closing panel 60 is restricted by the hinge receiving portion 54.

As shown in fig. 12 and 13, a rotation rib 63 is integrally formed at the lower end of the hinge piece 62. The rotation rib 63 extends in the left-right direction and is formed from the proximal end portion to the distal end portion of the hinge piece 62. The rotation rib 63 is formed in a substantially rectangular shape having a longitudinal direction in the front-rear direction when viewed in a cross section taken in the left-right direction, and protrudes to the front side and the rear side with respect to the hinge piece 62. Specifically, the amount of rearward projection of the rotation rib 63 with respect to the hinge piece 62 is larger than the amount of forward projection of the rotation rib 63 with respect to the hinge piece 62, and the rear end of the rotation rib 63 projects rearward beyond the tip end surface of the upper end of the panel side wall 61A. Further, the lower surface of the rotation rib 63 is curved in an arc shape that is convex obliquely downward and rearward, and is disposed close to the upper side of the lower corner of the hinge receiving portion 54 in the frame member 50. Therefore, when the opening/closing panel 60 rotates from the closing position to the rotational position, the following configuration is provided: the lower surface of the rotation rib 63 is guided by the lower corner of the hinge receiving portion 54, and the hinge piece 62 rotates within the hinge receiving portion 54 (see the opening/closing panel 60 shown by an arrow and a two-dot chain line in fig. 13).

A sliding rib 64 is integrally formed at a middle portion in the vertical direction of the hinge piece 62. The sliding rib 64 extends in the left-right direction, and is formed from the base end portion to the tip end portion of the hinge piece 62, similarly to the rotating rib 63. The sliding rib 64 is formed in a substantially rectangular shape having a longitudinal direction in the front-rear direction when viewed in a cross section taken in the left-right direction, and protrudes forward and rearward with respect to the hinge piece 62. Specifically, the amount of protrusion of the sliding rib 64 to the front side of the hinge piece 62 is set to be the same as the amount of protrusion of the rotating rib 63 to the front side of the hinge piece 62. On the other hand, the amount of rearward projection of the sliding rib 64 with respect to the hinge piece 62 is set larger than the amount of rearward projection of the rotating rib 63 with respect to the hinge piece 62, and the rear end portion of the sliding rib 64 projects rearward beyond the distal end surface of the upper end portion of the panel side wall 61A. More specifically, the distance L from the front surface of the opening/closing panel 60 to the rear end surface of the sliding rib 64 in the front-rear direction is set to be the same as the maximum value T1max of the thickness T1 of the panel side wall 61A. That is, the distance L is set to be the same as the thickness T1max of the lower end portion of the panel side wall 61A.

The rear end surface of the sliding rib 64 is configured as a sliding surface 64A, and the sliding surface 64A is curved in a substantially arc shape that is convex to the rear side when viewed in the left-right direction. When the opening/closing panel 60 is rotated to the rotational position, the following configuration is adopted: the sliding surface 64A of the sliding rib 64 abuts against the upper surface of the support wall 57 of the frame member 50 (see the opening/closing panel 60 shown by the two-dot chain line in fig. 13). When the opening/closing panel 60 slides rearward from the rotational position to the storage position, the following configuration is provided: the tip end of the hinge piece 62 is inserted into the rail portion 28 of the box main body 20, and the sliding surface 64A of the sliding rib 64 slides on the rail wall 27 of the box main body 20. Further, the following configuration is adopted when the opening/closing panel 60 slides: the panel side wall 61A slides back and forth in the frame side insertion portion 58. Further, a thickness T2 (a vertical dimension, see fig. 13) of the sliding rib 64 is set to be thicker (larger) than a thickness T3 (a vertical dimension, see fig. 13) of the rotating rib 63.

A reinforcing rib 65 is integrally formed at the upper end of the hinge piece 62. The reinforcing rib 65 extends in the left-right direction, and is formed from the base end portion to the tip end portion of the hinge piece 62, similarly to the rotating rib 63. The reinforcing ribs 65 are formed in a substantially rectangular shape whose longitudinal direction is the front-rear direction, and protrude toward the front and rear sides with respect to the hinge pieces 62, in a cross-sectional view viewed from the left-right direction. Specifically, the amount of protrusion of the reinforcing rib 65 to the front side of the hinge piece 62 is set to be the same as the amount of protrusion of the rotating rib 63 to the front side of the hinge piece 62. The amount of rearward projection of the reinforcing rib 65 from the hinge piece 62 is set to be the same as the amount of rearward projection of the rotating rib 63 from the hinge piece 62. In the storage position of the opening/closing panel 60, the reinforcing rib 65 of the hinge piece 62 abuts against the stopper 26 of the box main body 20, and the movement of the opening/closing panel 60 to the rear side is restricted.

Further, a panel groove portion 60A opened to the front side is formed in the outer peripheral portion of the opening/closing panel 60. The panel groove portion 60A extends in the circumferential direction of the opening/closing panel 60 and is formed in a rectangular ring shape when viewed from the front. The lower panel groove portion 60A has a lock portion 66 protruding downward at the widthwise center portion of the opening/closing panel 60. A panel hook 66A protruding downward is formed at the lower end of the lock portion 66. At the closing position of the opening/closing panel 60, the panel hook portion 66A engages with the hook 59 of the frame member 50, and the rotation of the opening/closing panel 60 to the front side is restricted.

Further, a handle portion 67 is formed at the lower end portion of the opening/closing panel 60 at the center portion in the width direction, and the lower end portion of the handle portion 67 is cut into a concave shape that opens downward. At the closing position of the opening/closing panel 60, the handle portion 67 is disposed in the handle recess 50A of the frame member 50. Thus, the user can operate the opening/closing panel 60 by holding the grip portion 67.

When the opening/closing panel 60 is attached to the frame member 50, the opening/closing panel 60 in a horizontal state is disposed on the rear side of the frame member 50, and the panel side wall 61A of the opening/closing panel 60 is inserted into the frame side insertion portion 58 of the frame member 50 from the rear side. Thus, the hinge piece 62 of the opening/closing panel 60 is disposed in the frame-side insertion portion 58 and the hinge housing portion 54, and the opening/closing panel 60 is disposed at the rotational position. In this state, the opening/closing panel 60 attached to the frame member 50 can be placed at the closing position by rotating the opening/closing panel 60 relative to the frame member 50. Then, the assembly of the storage box 10 is completed by attaching the frame member 50 to the box main body 20 and the top plate 40 in a state where the opening/closing panel 60 is attached to the frame member 50. In addition, in a state of a bundle pack of the storage box 10 or the like, the frame member 50 in a state where the opening/closing panel 60 is attached is held by the top panel 40, and thus the top panel 40 in a state where the frame member 50 and the opening/closing panel 60 are held can be stacked on top of each other.

(Effect)

Next, the operation and effect of the present embodiment will be described.

In the storage box 10 configured as described above, as shown in fig. 1, the opening 56 of the frame member 50 is closed by the opening/closing panel 60 at the closing position of the opening/closing panel 60. When the stored items are stored in the storage section 24 of the box main body 20, the user grips the handle portion 67 of the opening/closing panel 60 to rotate the opening/closing panel 60 forward. Thus, the lower surface of the rotation rib 63 of the hinge piece 62 in the opening/closing panel 60 is guided by the lower corner of the hinge receiving portion 54 of the frame member 50, and the hinge piece 62 rotates in the hinge receiving portion 54. As a result, the opening/closing panel 60 is disposed at the rotational position (see fig. 15A).

Next, the user pushes the opening/closing panel 60 at the rotated position to the rear side to slide it. Thus, the tip end portion of the hinge piece 62 of the opening/closing panel 60 is inserted into the rail portion 28 of the box main body 20, and the sliding surface 64A of the sliding rib 64 of the hinge piece 62 slides on the rail wall 27 of the box main body 20. At this time, the panel side wall 61A of the opening/closing panel 60 slides inside the frame-side insertion portion 58 of the frame member 50. The upper end of the hinge piece 62 abuts against the stopper 26 of the box main body 20, so that the sliding of the opening/closing panel 60 to the rear side is restricted, and the opening/closing panel 60 is disposed at the storage position. Thus, the opening 56 of the frame member 50 is opened in a state where the opening/closing panel 60 is accommodated in the storage box 10. Therefore, the user can store the stored material from the opening 56 into the storage portion 24 of the box main body 20.

After the storage is stored in the storage section 24 of the box main body 20, the user pulls out the opening/closing panel 60 from the storage position to the rotational position, and rotates the opening/closing panel 60 at the rotational position to the rear side, thereby disposing the opening/closing panel 60 at the closing position. Thereby, the opening 56 is closed by the opening and closing panel 60.

Here, the storage box 10 includes a rectangular box-shaped box body 20 opened to the front and upper sides, and a top plate 40 attached to the upper end portion of the box body 20, and a rectangular frame-shaped frame member 50 is attached to the front end portion (box-side attachment portion 25) of the box body 20 and the front end portion (top plate-side attachment portion 47) of the top plate 40. Therefore, the front end of the box main body 20 and the front end of the top plate 40 are reinforced by the frame member 50. This allows the frame member 50 to increase the rigidity of the distal end portion of the storage box 10. The opening/closing panel 60 is rotatably attached to the frame member 50. The opening/closing panel 60 is disposed at the rotated position by being rotated from the closed position to the front side, and is disposed at the housed position by being slid on the rail portion 28 of the box main body 20 by being slid from the rotated position to the rear side. Accordingly, in the storage position, the opening/closing panel 60 is mostly stored in the box main body 20, and therefore, the user can take in and out the stored articles from and from the storage box 10 with improved convenience.

In addition, the frame member 50 is formed in a rectangular frame shape. Thus, when the storage boxes 10 are stacked vertically, the rectangular frame members 50 are arranged vertically, and therefore the appearance of the front surface of the storage boxes 10 in the stacked state can be made rectangular. In addition, when the storage boxes 10 are arranged side by side, the storage boxes 10 can be arranged in close contact with the side surfaces of the frame members 50 arranged side by side. Therefore, the design when the plurality of storage boxes 10 are arranged in an array can be improved. The opening 56 of the storage box 10 is formed by the frame member 50 as a single member. Therefore, the design of the storage box 10 when the opening 56 is opened can be improved.

Further, a pair of left and right hinge pieces 62 protruding outward in the width direction are formed at the upper end portion of the opening/closing panel 60. The hinge piece 62 is formed with: a rotation rib 63 guided by the hinge receiving portion 54 of the frame member 50 when the opening/closing panel 60 rotates; and a sliding rib 64 that slides on the rail portion 28 (rail wall 27) of the box main body 20 when the opening/closing panel 60 slides, and a thickness T2 of the sliding rib 64 is set to be thicker than a thickness T3 of the rotating rib 63. Therefore, not only the opening/closing panel 60 can be slid satisfactorily, but also the abrasion of the sliding rib 64 can be reduced. Further, by providing the rotation rib 63 and the sliding rib 64 separately, it is possible to reduce wear of the rotation rib 63 and the sliding rib 64 during rotation and sliding of the opening/closing panel 60.

Further, in the frame member 50, at the storage position of the opening/closing panel 60, a support wall 57 for supporting the lower end portion of the panel side wall 61A of the opening/closing panel 60 is formed. Further, the front end surface (rear end surface) of the panel side wall 61A of the opening/closing panel 60 is inclined rearward as it goes downward, and the rear end portion of the sliding rib 64 of the opening/closing panel 60 protrudes rearward beyond the upper end portion of the panel side wall 61A. This improves the sliding performance of the opening/closing panel 60 and improves the design of the storage box 10 when the opening/closing panel 60 is disposed at the storage position. This point will be described below in comparison with the opening/closing panel 60 of the comparative example.

In the opening/closing panel 60 of the comparative example, the front end surface (rear end surface) of the panel side wall 61A of the opening/closing panel 60 is formed in the vertical direction. That is, the thickness T1 of the panel side wall 61A of the opening/closing panel 60 is set to be constant in the vertical direction. In the opening/closing panel 60 of the comparative example, the position of the rear end face of the sliding rib 64 of the opening/closing panel 60 coincides with the position of the distal end face of the panel side wall 61A in the front-rear direction. That is, the rear end portion of the sliding rib 64 does not protrude rearward beyond the distal end surface of the panel side wall 61A.

Here, when the opening/closing panel 60 slides rearward from the rotated position, the sliding rib 64 of the opening/closing panel 60 slides on the upper surface of the rail wall 27 of the box main body 20, and the panel side wall 61A of the opening/closing panel 60 slides in the frame-side insertion portion 58 of the frame member 50. That is, the panel side wall 61A slides on the upper side of the support wall 57 of the frame member 50.

As shown in fig. 16 (a), when the opening/closing panel 60 of the comparative example in the horizontal state is slid rearward from the rotational position, the rear end surface of the sliding rib 64 does not protrude rearward beyond the front end surface of the panel side wall 61A, and therefore the front end surface of the panel side wall 61A slides in surface contact with the support wall 57. Therefore, the sliding resistance of the opening/closing panel 60 in the comparative example tends to increase when the opening/closing panel 60 slides.

For example, when the opening/closing panel 60 is temporarily warped forward at the center in the width direction after the opening/closing panel 60 is molded, the vertical gap G between the front surface of the opening/closing panel 60 and the upper end of the opening 56 of the frame member 50 is reduced. Thus, in the opening/closing panel 60 of the comparative example, the opening/closing panel 60 interferes with (the upper end portion of) the opening 56 due to the influence of warpage or the like after the molding of the opening/closing panel 60, and there is a possibility that the opening/closing panel 60 cannot be slid satisfactorily.

In contrast, in the present embodiment, as described above, the front end surface (rear end surface) of the panel side wall 61A of the opening/closing panel 60 is inclined rearward as it goes downward, and the rear end portion of the sliding rib 64 of the opening/closing panel 60 protrudes rearward beyond the upper end portion of the panel side wall 61A. Therefore, as shown in fig. 16B, the opening/closing panel 60 of the present embodiment can prevent the distal end surface of the panel side wall 61A from coming into contact with the support wall 57 when the opening/closing panel 60 in the horizontal state is slid rearward from the rotational position (see the opening/closing panel 60 shown by the two-dot chain line in fig. 16B). Therefore, the sliding resistance of the opening/closing panel 60 during sliding can be reduced as compared with the comparative example.

Further, when the opening/closing panel 60 is temporarily warped forward in the widthwise central portion thereof after the opening/closing panel 60 is molded, the opening/closing panel 60 can be slid rearward by slightly tilting the opening/closing panel 60 downward toward the front side (see the opening/closing panel 60 shown by a one-dot chain line in fig. 16B). This makes it possible to make the vertical gap G between the front surface of the opening/closing panel 60 and the upper end of the opening 56 of the frame member 50 during sliding of the opening/closing panel 60 larger than that of the comparative example. Therefore, for example, even when the widthwise central portion of the opening/closing panel 60 after molding is temporarily warped to the front side, interference between the opening/closing panel 60 and (the upper end portion of) the opening portion 56 is suppressed, and the opening/closing panel 60 can be satisfactorily slid.

The distance L from the front surface of the opening/closing panel 60 to the rear end surface of the sliding rib 64 in the front-rear direction is set to be the same as the thickness T1max of the lower end portion of the panel side wall 61A. Further, at the storage position of the opening/closing panel 60, the distal end surface of the lower end portion of the panel side wall 61A is supported from below by the support wall 57 of the frame member 50. That is, the thick lower end portion of the panel side wall 61A is supported by the support wall 57. Therefore, the opening/closing panel 60 can be placed in the horizontal state at the storage position. This can suppress an increase in the vertical gap G between the upper end of the opening 56 of the frame member 50 and the front surface of the opening/closing panel 60 at the storage position of the opening/closing panel 60. As described above, the sliding performance of the opening/closing panel 60 can be improved, and the design of the storage box 10 when the opening/closing panel 60 is disposed at the storage position can be improved.

In the present embodiment, in the disassembled state of the storage box 10, the upper end portions of the fitting ribs 30 of the lower box main body 20 are fitted into the fitting groove portions 31A of the upper box main body 20, whereby the box main bodies 20 can be fitted to each other. That is, the plurality of box bodies 20 can be fitted into each other by groove fitting. Therefore, the plurality of box bodies 20 can be nested with a simple configuration.

Further, the upper end surface of the fitting rib 30 and the upper end surface of the fitting groove portion 31A in the fitted portion 31 are inclined upward toward the inside in the width direction of the box main body 20 as viewed from the front. Therefore, when the fitting rib 30 is fitted into the fitting groove portion 31A, the upper end surface of the fitting rib 30 abuts against the upper end surface of the fitting groove portion 31A. Thus, when the plurality of box bodies 20 are nested, the fitting rib 30 and the fitting groove portion 31A are engaged in the left-right direction. Thus, when the fitting rib 30 and the fitting groove portion 31A are brought into contact and fitted to each other, even if a load is applied from the upper direction (vertical direction), the nested state is maintained, and the side wall 22 of the box main body 20 is prevented from being deformed outward in the width direction. Therefore, stability in a state where the box main bodies 20 are nested can be ensured.

The top plate 40 has a holding portion 46 for holding the frame member 50. Therefore, in the state where the storage box 10 is disassembled, the frame member 50 to which the opening/closing panel 60 is attached can be held by the top plate 40. This can improve the performance of the bundle package, for example, when the storage box 10 is transported in a disassembled state.
