Summary of the Invention

Problems to be Solved by the Invention

[0004] The assembled container disclosed in Patent Document 1 has a problem that its deformation tends to be large when it receives force. The present invention solves such a problem. The present invention aims to provide an assembled container in which deformation when receiving force after assembly is suppressed.

Means for Solving the Problems

[0005] The assembled container of the present invention will be described with reference to the drawings. The reference numerals in the drawings are used in this section to assist in understanding the content of the invention. Using the reference numerals in the drawings in this section is not intended to limit the content of the invention to the illustrated scope.

[0006] To achieve the above-described object, according to one aspect of the present invention, the prefabricated container 10 includes a pair of side plate portions 70, 72, a pair of end plate portions 74, 76, a bottom plate portion 78, end plate connecting portions 80, 82, and side plate connecting portions 84, 86. The pair of side plate portions 70, 72 extend along each other. The pair of end plate portions 74, 76 extend along each other. The pair of end plate portions 74, 76 extend such that one intersects the pair of side plate portions 70, 72 at one end of the pair of side plate portions 70, 72 and the other intersects the pair of side plate portions 70, 72 at the other end of the pair of side plate portions 70, 72. The end plate connecting portions 80, 82 connect the pair of end plate portions 74, 76 to the bottom plate portion 78 so that the pair of end plate portions 74, 76 can be in a state of falling over while overlapping the bottom plate portion 78 and a state of protruding from the bottom plate portion 78. The side plate connecting portions 84, 86 connect the pair of side plate portions 70, 72 to the bottom plate portion 78 so that the pair of side plate portions 70, 72 can be in a state of falling over while overlapping the end plate portions 74, 76 and a state of protruding from the bottom plate portion 78. One of the pair of end plate portions 74, 76 has an end plate one main body portion 100 and a one end plate one end side protruding portion 102. The end plate one main body portion 100 is continuous with the end plate connecting portion 80. The end plate one main body portion 100 extends so as to intersect the pair of side plate portions 70, 72. The one end plate one end side protruding portion 102 protrudes in the direction in which the end plate one main body portion 100 extends. The one end plate one end side protruding portion 102 protrudes from a location described below among the positions different from the protruding end 120 of the end plate one main body portion 100. That location is the location where one of the pair of end plate portions 74, 76 protruding from the bottom plate portion 78 and one of the pair of side plate portions 70, 72 protruding from the bottom plate portion 78 are in contact with each other. The prefabricated container 10 further includes a one connecting band 88. The one connecting band 88 can be deformed so that the pair of side plate portions 70, 72 can fall over while overlapping one of the pair of end plate portions 74, 76. The one connecting band 88 supports the pair of side plate portions 70, 72 and one of the pair of end plate portions 74, 76 so that the pair of side plate portions 70, 72 and one of the pair of end plate portions 74, 76 do not fall to the outer peripheral side of the bottom plate portion 78. The one connecting band 88 connects one end of one of the pair of end plate portions 74, 76 and one end of the other of the pair of end plate portions 74, 76. One of the pair of side plate portions 70, 72 has a one side plate one end side concave portion 160 formed therein. The one side plate one end side concave portion 160 is formed at a position facing the one end plate one end side protruding portion 102, different from the protruding ends 120, 122 of one of the pair of side plate portions 70, 72, among the locations described below. That location is the end plate portion 74 When one of the pair of <76> and one of the pair of side plate portions <70, 72> protrude from the bottom plate portion <78>, it is the location where it contacts the one end plate one - end - side protrusion <102>. The one - end - side recess <160> of one side plate can fit the one end plate one - end - side protrusion <102>.

[0007] When the one end plate one - end - side protrusion <102> fits into the one - end - side recess <160> of one side plate, it is prevented that one of the pair of end plate portions <74, 76> having the one end plate one - end - side protrusion <102> falls so as to overlap the bottom plate portion <78>. On the other hand, it is prevented by the one connecting band <88> that the pair of side plate portions <70, 72> and one of the pair of end plate portions <74, 76> fall to the outer peripheral side of the bottom plate portion <78>. Thereby, compared with the case where deformation is prevented relying on the frictional force between the engaging protrusion and the engaging hole, the deformation of the assembled container <10> when receiving a force is suppressed. Moreover, the one end plate one - end - side protrusion <102> protrudes from a position different from the protruding end <120> of the one end plate main body portion <100>. The one - end - side recess <160> of one side plate is formed so as to face the location where the one end plate one - end - side protrusion <102> protrudes from the one end plate main body portion <100>. Thereby, compared with the case where the following two requirements are satisfied, the force required to tilt the end plate portion having the one end plate one - end - side protrusion <102> fitted into the one - end - side recess <160> of one side plate toward the bottom plate portion <78> becomes larger. One of those two requirements is that the one end plate one - end - side protrusion <102> protrudes from the protruding end <120> of the one end plate main body portion <100>. The other of those two requirements is that the one end plate one - end - side protrusion <102> is fitted into the one - end - side recess <160> of one side plate formed so that the one end plate one - end - side protrusion <102> can be fitted. The reason why the force required to tilt toward the bottom plate portion <78> becomes larger is that the magnitude of the force required to sufficiently push and expand the pair of side plate portions <70, 72> by that force increases. When the magnitude increases, the deformation of the assembled container <10> when receiving a force is suppressed. As a result, an assembled container is provided in which deformation when receiving a force after assembly is suppressed.

[0008] Further, it is desirable that the above-described one-side plate one-end-side recess 160 has a recess bottom portion 180 serving as a bottom and a pair of side support portions 182 and 184. The pair of side support portions 182 and 184 are arranged on one side and the other side of the recess bottom portion 180. The pair of side support portions 182 and 184 support both sides of the one-end plate one-end-side protrusion 102 when the one-end plate one-end-side protrusion 102 contacts the recess bottom portion 180.

[0009] The pair of side support portions 182 and 184 support both sides of the one-end plate one-end-side protrusion 102. Thereby, compared with the case where only the center of the one-end plate one-end-side protrusion 102 is supported, the stress applied to the one-end plate one-end-side protrusion 102 fitted in the one-side plate one-end-side recess 160 is suppressed. Since the stress is suppressed, the deformation of the end plate portions 74 and 76 having this is also suppressed.

[0010] Alternatively, it is desirable that the interval between the above-described pair of side support portions 182 and 184 becomes narrower as it approaches the recess bottom portion 180.

[0011] When the interval between the pair of side support portions 182 and 184 becomes narrower as it approaches the recess bottom portion 180, the one-end plate one-end-side protrusion 102 fitted in the one-side plate one-end-side recess 160 becomes difficult to move. Since the one-end plate one-end-side protrusion 102 becomes difficult to move, the deformation of the assembled container 10 due to its ease of movement is suppressed.

[0012] Alternatively, it is desirable that the shape of the above-described one-end plate one-end-side protrusion 102 is trapezoidal. In this case, it is desirable that the side support portions 182 and 184 have a recess bottom connection portion 200 and a convex curved surface forming portion 202. The recess bottom connection portion 200 is continuous with the recess bottom portion 180. The convex curved surface forming portion 202 is continuous with the recess bottom connection portion 200. The convex curved surface forming portion 202 forms a curved surface along the outer peripheral surface of a circle.

[0013] Further, it is desirable that the above-described one connecting band 88 supports the range from the protruding end 120 of the end plate one main body portion 100 to the one-end plate one-end-side protrusion 102 in one of the pair of end plate portions 74 and 76.

[0014] The range from the protruding end 120 of the main body portion 100 of one side of the end plate to the protruding portion 102 on one end side of the one end plate is supported by the one connecting band 88. Thereby, when a force capable of tilting the side having the protruding portion 102 on one end side of the one end plate among the pair of end plate portions 74, 76 toward the bottom plate portion 78 is applied to that range, that force is also supported by the one connecting band 88. When that force is supported by the one connecting band 88, a part of that force will narrow both ends of the pair of side plate portions 70, 72. When both ends of the pair of side plate portions 70, 72 are narrowed, the protruding portion 102 on one end side of the one end plate becomes difficult to come off from the concave portion 160 on one end side of the one side plate.

Advantages of the Invention

[0015] According to the present invention, deformation when receiving a force after assembly can be suppressed.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are the same. Therefore, detailed descriptions thereof will not be repeated.

[0018] [Description of Structure] FIG. 1 is a perspective view of the assembled container 10 according to the present embodiment. FIG. 2 is a view showing the folding state of the assembled container 10 according to the present embodiment. Based on FIGS. 1 and 2, the configuration of the assembled container 10 according to the present embodiment will be described.

[0019] The assembled container 10 according to the present embodiment includes one side plate portion 70, the other side plate portion 72, one end plate portion 74, the other end plate portion 76, a bottom plate portion 78, one end plate connecting portion 80, the other end plate connecting portion 82, one side plate connecting portion 84, the other side plate connecting portion 86, one connecting band 88, and the other connecting band 90.

[0020] The one side plate portion 70 and the other side plate portion 72 extend along each other. In the present embodiment, the one side plate portion 70 and the other side plate portion 72 are collectively referred to as the "side plate portion". Therefore, the assembled container 10 according to the present embodiment includes a pair of side plate portions.

[0021] The one end plate portion 74 and the other end plate portion 76 extend along each other. In the present embodiment, the one end plate portion 74 and the other end plate portion 76 are collectively referred to as the "end plate portion". Therefore, the assembled container 10 according to the present embodiment includes a pair of end plate portions. Particularly as is clear from FIG. 1, the one end plate portion 74 intersects the one side plate portion 70 and the other side plate portion 72 at one end thereof. The other end plate portion 76 intersects the one side plate portion 70 and the other side plate portion 72 at the other end thereof.

[0022] The bottom plate portion 78 forms the bottom of the assembled container 10 according to the present embodiment. In the present embodiment, the shape of the bottom plate portion 78 is rectangular and plate-like.

[0023] One end - plate connecting portion 80 connects one end - plate portion 74 to the bottom - plate portion 78 so that it can be in a state of lying on top of the bottom - plate portion 78 and a state of protruding from the bottom - plate portion 78. In the present embodiment, one end - plate connecting portion 80 consists of a single fold line. The other end - plate connecting portion 82 connects the other end - plate portion 76 to the bottom - plate portion 78 so that it can be in a state of lying on top of the bottom - plate portion 78 and a state of protruding from the bottom - plate portion 78. In the present embodiment, the other end - plate connecting portion 82 also consists of a single fold line. In the present embodiment, one end - plate connecting portion 80 and the other end - plate connecting portion 82 are collectively referred to as the "end - plate connecting portion". Therefore, the pre - assembled container 10 according to the present embodiment includes a pair of end - plate connecting portions.

[0024] One side - plate connecting portion 84 connects one side - plate portion 70 to the bottom - plate portion 78 so that it can be in a state of overlapping one end - plate portion 74 and the other end - plate portion 76 and a state of protruding from the bottom - plate portion 78. In the present embodiment, one side - plate connecting portion 84 consists of a pair of fold lines extending along each other. One of those pairs of fold lines contributes to the connection between one side - plate portion 70 and the bottom - plate portion 78. The other of those pairs of fold lines enables a state of overlapping one end - plate portion 74 and the other end - plate portion 76 and a state of protruding from the bottom - plate portion 78.

[0025] The other side - plate connecting portion 86 connects the other side - plate portion 72 to the bottom - plate portion 78 so that it can be in a state of overlapping one end - plate portion 74 and the other end - plate portion 76 and a state of protruding from the bottom - plate portion 78. In the present embodiment, the other side - plate connecting portion 86 consists of a pair of fold lines extending along each other. One of those pairs of fold lines contributes to the connection between the other side - plate portion 72 and the bottom - plate portion 78. The other of those pairs of fold lines enables a state of overlapping one end - plate portion 74 and the other end - plate portion 76 and a state of protruding from the bottom - plate portion 78.

[0026] In the present embodiment, one side - plate connecting portion 84 and the other side - plate connecting portion 86 are collectively referred to as the "side - plate connecting portion". Therefore, the pre - assembled container 10 according to the present embodiment includes a pair of side - plate connecting portions.

[0027] In the case of this embodiment, one connecting strip 88 is a paper-made and strip-shaped member. One end of the one connecting strip 88 is attached to one end of the one side plate portion 70. The other end of the one connecting strip 88 is attached to one end of the other side plate portion 72. The one connecting strip 88 covers from the protruding end 120 of the one side plate portion 70 to the location where it contacts the one side plate connecting portion 84. The one connecting strip 88 covers from the protruding end 122 of the other side plate portion 72 to the location where it contacts the other side plate connecting portion 86. As a result, when the one side plate portion 70 and the other side plate portion 72 protrude from the bottom plate portion 78, the one connecting strip 88 extends from one end of the one side plate portion 70 to one end of the other side plate portion 72. Consequently, the one connecting strip 88 connects the one side plate portion 70 and the other side plate portion 72 at one end of the one side plate portion 70 and one end of the other side plate portion 72.

[0028] In the case of this embodiment, the other connecting strip 90 is a paper-made and strip-shaped member. One end of the other connecting strip 90 is attached to the other end of the one side plate portion 70. The other end of the other connecting strip 90 is attached to the other end of the other side plate portion 72. The other connecting strip 90 covers from the protruding end 120 of the one side plate portion 70 to the location where it contacts the one side plate connecting portion 84. The other connecting strip 90 covers from the protruding end 122 of the other side plate portion 72 to the location where it contacts the other side plate connecting portion 86. As a result, when the one side plate portion 70 and the other side plate portion 72 protrude from the bottom plate portion 78, the other connecting strip 90 extends from the other end of the one side plate portion 70 to the other end of the other side plate portion 72. Consequently, the other connecting strip 90 connects the one side plate portion 70 and the other side plate portion 72 at the other end of the one side plate portion 70 and the other end of the other side plate portion 72.

[0029] As described above, in the case of this embodiment, the one connecting band 88 and the other connecting band 90 are made of paper. Therefore, as shown in FIG. 2, the one connecting band 88 according to this embodiment can be deformed such that one end of the one side plate portion 70 and one end of the other side plate portion 72 can overlap and fall on the one end plate portion 74. The other connecting band 90 according to this embodiment can be deformed such that the other end of the one side plate portion 70 and the other end of the other side plate portion 72 can overlap and fall on the other end plate portion 76. In this embodiment, the one connecting band 88 and the other connecting band 90 are collectively referred to as the "connecting band". Therefore, the assembled container 10 according to this embodiment includes a pair of connecting bands.

[0030] As described above, in the case of this embodiment, the one connecting band 88 connects the one side plate portion 70 and the other side plate portion 72 at one end of the one side plate portion 70 and one end of the other side plate portion 72. As a result, as shown in FIG. 1, when the one side plate portion 70 and the other side plate portion 72 protrude from the bottom plate portion 78, the one connecting band 88 supports the protruding end 120 of the one side plate portion 70, the protruding end 122 of the other side plate portion 72, and the protruding end 124 of the one end plate portion 74. Since it is supported in such a manner, it is possible to prevent the one side plate portion 70, the other side plate portion 72, and the one end plate portion 74 from falling to the outer peripheral side of the bottom plate portion 78.

[0031] Similarly, in the case of this embodiment, the other connecting band 90 connects the one side plate portion 70 and the other side plate portion 72 at the other end of the one side plate portion 70 and the other end of the other side plate portion 72. As a result, as shown in FIG. 1, when the one side plate portion 70 and the other side plate portion 72 protrude from the bottom plate portion 78, the other connecting band 90 supports the protruding end 120 of the one side plate portion 70, the protruding end 122 of the other side plate portion 72, and the protruding end 126 of the other end plate portion 76. Since it is supported in such a manner, it is possible to prevent the one side plate portion 70, the other side plate portion 72, and the other end plate portion 76 from falling to the outer peripheral side of the bottom plate portion 78.

[0032] FIG. 3 is a developed view of the prefabricated container 10 according to the present embodiment. However, the one connecting strip 88 and the other connecting strip 90 are not shown in FIG. 3. FIG. 4 is a view showing an end portion on one end side of the one side plate portion 70 as viewed from the outside of the prefabricated container 10 according to the present embodiment. Based on FIGS. 3 and 4, the configuration of the one side plate portion 70 according to the present embodiment will be described.

[0033] In the case of the present embodiment, a one side plate one end side recess 160 and a one side plate other end side recess 162 are formed in the one side plate portion 70. The one side plate one end side recess 160 is formed at a position different from the protruding end 120 of the one side plate portion 70 when it protrudes from the bottom plate portion 78. More specifically, the one side plate one end side recess 160 is formed near the center of one end of the one side plate portion 70. The one side plate other end side recess 162 is also formed at a position different from the protruding end 120 of the one side plate portion 70 when it protrudes from the bottom plate portion 78. More specifically, the one side plate other end side recess 162 is formed near the center of the other end of the one side plate portion 70.

[0034] As shown in FIG. 4, in the case of the present embodiment, the one side plate one end side recess 160 has a recess bottom portion 180 serving as a bottom, a one side support portion 182, and a other side support portion 184. The one side support portion 182 is disposed on one side of the recess bottom portion 180. The other side support portion 184 is disposed on the other side of the recess bottom portion 180. The one side support portion 182 and the other side support portion 184 support both sides of the one end plate one end side protruding portion 102 when the one end plate one end side protruding portion 102 contacts the recess bottom portion 180. As is apparent from FIG. 4, in the case of the present embodiment, the interval between the one side support portion 182 and the other side support portion 184 becomes narrower as it approaches the recess bottom portion 180. As is apparent from FIG. 4, in the case of the present embodiment, the one side support portion 182 has a recess bottom connecting portion 200 and a convex curved surface forming portion 202. The recess bottom connecting portion 200 is continuous with the recess bottom portion 180. The convex curved surface forming portion 202 is continuous with the recess bottom connecting portion 200. As is apparent from FIG. 4, the convex curved surface forming portion 202 forms a curved surface along the outer peripheral surface of a circle. In the case of the present embodiment, the other side support portion 184 also has a recess bottom connecting portion 200 and a convex curved surface forming portion 202.

[0035] In the case of this embodiment, the configuration of the recess 162 at the other end side of the one side plate is the same as that of the recess 160 at the one end side of the one side plate. Therefore, the detailed description thereof will not be repeated here.

[0036] Next, the configuration of the other side plate portion 72 according to this embodiment will be described. In this embodiment, the other side plate portion 72 is formed with an other side plate one - end - side recess 164 and an other side plate other - end - side recess 166. The other side plate one - end - side recess 164 is formed at a position different from the protruding end 122 of the other side plate portion 72 when the other side plate portion 72 protrudes from the bottom plate portion 78. More specifically, the other side plate one - end - side recess 164 is formed near the center of one end of the other side plate portion 72. The other side plate other - end - side recess 166 is also formed at a position different from the protruding end 122 of the other side plate portion 72 when the other side plate portion 72 protrudes from the bottom plate portion 78. More specifically, the other side plate other - end - side recess 166 is formed near the center of the other end of the other side plate portion 72.

[0037] In the case of this embodiment, the configurations of the other side plate one - end - side recess 164 and the other side plate other - end - side recess 166 are the same as that of the one side plate one - end - side recess 160. Therefore, the detailed description thereof will not be repeated here.

[0038] FIG. 5 is a view showing an end portion on one - end - side of the one end - plate portion 74 as seen from the inside of the assembled container 10 according to this embodiment. Based on FIGS. 3 and 5, the configuration of the one end - plate portion 74 according to this embodiment will be described.

[0039] As shown in FIG. 3, in the case of this embodiment, the one end - plate portion 74 has an end - plate one main body portion 100, a one end - plate one - end - side protruding portion 102, and a one end - plate other - end - side protruding portion 104.

[0040] The end - plate one main body portion 100 is continuous with the one end - plate connecting portion 80. The end - plate one main body portion 100 extends so as to intersect the one side - plate portion 70 and the other side - plate portion 72.

[0041] One end - side protrusion 102 of one end - plate protrudes from one main - body part 100 of the end - plate. One end - side protrusion 102 of one end - plate protrudes in the direction in which one main - body part 100 of the end - plate extends. In the present embodiment, one end - side protrusion 102 of one end - plate protrudes from near the center of one end of one main - body part 100 of the end - plate. This one end is the portion that contacts one side - plate part 70 which also protrudes from the bottom - plate part 78 when one main - body part 100 of the end - plate protrudes from the bottom - plate part 78. As is clear from FIG. 5, in the case of the present embodiment, the shape of one end - side protrusion 102 of one end - plate is trapezoidal.

[0042] The other end - side protrusion 104 of one end - plate also protrudes from one main - body part 100 of the end - plate. The other end - side protrusion 104 of one end - plate also protrudes in the direction in which one main - body part 100 of the end - plate extends. However, the other end - side protrusion 104 of one end - plate protrudes in the direction opposite to that of one end - side protrusion 102 of one end - plate. In the present embodiment, the other end - side protrusion 104 of one end - plate protrudes from near the center of the other end of one main - body part 100 of the end - plate. This other end is the portion that contacts the other side - plate part 72 which also protrudes from the bottom - plate part 78 when one main - body part 100 of the end - plate protrudes from the bottom - plate part 78. In the case of the present embodiment, similar to one end - side protrusion 102 of one end - plate, the shape of the other end - side protrusion 104 of one end - plate is trapezoidal.

[0043] Next, the configuration of the other end - plate part 76 according to the present embodiment will be described. In the present embodiment, the other end - plate part 76 has an other end - plate main - body part 110, an other end - side protrusion 112 of the other end - plate, and an other end - side protrusion 114 of the other end - plate.

[0044] The other end - plate main - body part 110 is continuous with the other end - plate connecting part 82. The other end - plate main - body part 110 extends so as to intersect one side - plate part 70 and the other side - plate part 72.

[0045] The protruding portion 112 on one end side of the other end plate protrudes from the other main body portion 110 of the end plate. The protruding portion 112 on one end side of the other end plate protrudes in the direction in which the other main body portion 110 of the end plate extends. In the present embodiment, the protruding portion 112 on one end side of the other end plate protrudes from near the center of one end of the other main body portion 110 of the end plate. This one end is the portion that contacts the one side plate portion 70 that also protrudes from the bottom plate portion 78 when the other main body portion 110 of the end plate protrudes from the bottom plate portion 78. In the case of the present embodiment, similar to the protruding portion 102 on one end side of the one end plate, the shape of the protruding portion 112 on one end side of the other end plate is trapezoidal.

[0046] The protruding portion 114 on the other end side of the other end plate also protrudes from the other main body portion 110 of the end plate. The protruding portion 114 on the other end side of the other end plate also protrudes in the direction in which the other main body portion 110 of the end plate extends. However, the protruding portion 114 on the other end side of the other end plate protrudes in the direction opposite to that of the protruding portion 112 on one end side of the other end plate. In the present embodiment, the protruding portion 114 on the other end side of the other end plate protrudes from near the center of the other end of the other main body portion 110 of the end plate. This other end is the portion that contacts the other side plate portion 72 that also protrudes from the bottom plate portion 78 when the other main body portion 110 of the end plate protrudes from the bottom plate portion 78. In the case of the present embodiment, similar to the protruding portion 112 on one end side of the other end plate, the shape of the protruding portion 114 on the other end side of the other end plate is trapezoidal.

[0047] [Description of the manufacturing method] The assembled container 10 according to the present embodiment is manufactured by the steps described below. First, a wooden plate as a raw material is cut out into the shape indicated by the solid line in FIG. 3. Subsequently, creases are formed in the cut-out plate. Those creases are formed as indicated by the broken line in FIG. 3.

[0048] Next, the portions that will become the one end plate portion 74 and the other end plate portion 76 among the cut-out plates are raised, and the portion that will become the bottom plate portion 78 is laid down. As a result, those portions become the one end plate portion 74 and the other end plate portion 76.

[0049] When those portions are knocked down, the portion that becomes one side plate portion 70 and the portion that becomes the other side plate portion 72 are raised. As a result, those portions become the one side plate portion 70 and the other side plate portion 72. When those portions are raised, one end of one connecting band 88 is attached to one end of the one side plate portion 70. The other end of the one connecting band 88 is attached to one end of the other side plate portion 72. Since the one connecting band 88 is attached to those portions in a state where the portion that becomes the one side plate portion 70 and the portion that becomes the other side plate portion 72 are raised, the one connecting band 88 can be deformed so that the one side plate portion 70 and the other side plate portion 72 can overlap and fall on the one end plate portion 74.

[0050] Next, one end of the other connecting band 90 is attached to the other end of the one side plate portion 70. The other end of the other connecting band 90 is attached to the other end of the other side plate portion 72. Since the other connecting band 90 is attached to those portions in a state where the portion that becomes the one side plate portion 70 and the portion that becomes the other side plate portion 72 are raised, the other connecting band 90 can be deformed so that the one side plate portion 70 and the other side plate portion 72 can overlap and fall on the other end plate portion 76.

[0051] When the one connecting band 88 and the other connecting band 90 are attached, the one side plate portion 70 and the other side plate portion 72 are knocked down so as to overlap the one end plate portion 74 and the other end plate portion 76. The one connecting band 88 and the other connecting band 90 are folded and overlap the one end plate portion 74 and the other end plate portion 76. This situation is shown in FIG. 2. As a result, the assembled container 10 according to the present embodiment is completed.

[0052] [Explanation of Usage] The assembled container 10 according to the present embodiment is stored in the state shown in FIG. 2 until immediately before use. When in use, the one side plate portion 70 and the other side plate portion 72 of the assembled container 10 according to the present embodiment are raised. As a result, the one side plate portion 70 and the other side plate portion 72 protrude from the bottom plate portion 78. Along with this, the folded one connecting band 88 is passed from one end of the one side plate portion 70 to one end of the other side plate portion 72. Similarly, the folded other connecting band 90 is passed from the other end of the one side plate portion 70 to the other end of the other side plate portion 72.

[0053] Next, one end plate portion 74 is raised. Along with this, when the one end plate portion 74 protrudes from the bottom plate portion 78, the one end plate one - end - side protrusion 102 of the one end plate portion 74 fits into the one side plate one - end - side recess 160 of the one side plate portion 70. FIG. 6 is a view showing a situation where the one end plate one - end - side protrusion 102 of the one end plate portion 74 is fitted into the one side plate one - end - side recess 160 of the one side plate portion 70 according to this embodiment. Similarly, the one end plate other - end - side protrusion 104 of the one end plate portion 74 fits into the other side plate one - end - side recess 164 of the other side plate portion 72. In the case of this embodiment, in this way, when the one end plate one - end - side protrusion 102 fits into the one side plate one - end - side recess 160 and the one end plate other - end - side protrusion 104 fits into the other side plate one - end - side recess 164, the one end plate portion 74 comes into close contact with the one connecting band 88. Further, the one connecting band 88 covers the one side plate one - end - side recess 160 and the one end plate one - end - side protrusion 102 fitted therein. The one connecting band 88 also covers the other side plate one - end - side recess 164 and the one end plate other - end - side protrusion 104 fitted therein.

[0054] Next, the other end plate portion 76 is raised. Along with this, when the other end plate portion 76 protrudes from the bottom plate portion 78, the other end plate one - end - side protrusion 112 of the other end plate portion 76 fits into the one side plate other - end - side recess 162 of the one side plate portion 70. The other end plate other - end - side protrusion 114 of the other end plate portion 76 fits into the other side plate other - end - side recess 166 of the other side plate portion 72. In the case of this embodiment, in this way, when the other end plate one - end - side protrusion 112 fits into the one side plate other - end - side recess 162 and the other end plate other - end - side protrusion 114 fits into the other side plate other - end - side recess 166, the other end plate portion 76 comes into close contact with the other connecting band 90. Further, the other connecting band 90 covers the one side plate other - end - side recess 162 and the other end plate one - end - side protrusion 112 fitted therein. The other connecting band 90 also covers the other side plate other - end - side recess 166 and the other end plate other - end - side protrusion 114 fitted therein.

[0055] When one end plate portion 74 is in close contact with one connecting band 88 and the other end plate portion 76 is in close contact with the other connecting band 90, the prefabricated container 10 according to the present embodiment is in a state where it can accommodate objects therein. After the prefabricated container 10 according to the present embodiment is in a state where it can accommodate objects, it is used in the same usage method as a well-known food container. The specific content of the usage method is well-known. Therefore, the detailed description thereof will not be repeated here.

[0056] [Effects of the prefabricated container according to the present embodiment] Hereinafter, the effects of the prefabricated container 10 according to the present embodiment will be described.

[0057] In the prefabricated container 10 according to the present embodiment, the fall of the pair of side plate portions and one end plate portion 74 to the outer peripheral side of the bottom plate portion 78 is prevented by the one connecting band 88. The fall of the one end plate portion 74 so as to overlap the bottom plate portion 78 is prevented by the fitting of the one end plate one - side end protrusion 102 into the one side plate one - side end recess 160. At this time, the one end plate one - side end protrusion 102 protrudes from near the center of one end of the end plate one - side main body portion 100. The one side plate one - side end recess 160 is formed so as to face the position where the one end plate one - side end protrusion 102 protrudes. Thereby, the force required to tilt the one end plate portion 74 toward the bottom plate portion 78 increases. When the force increases, the deformation of the prefabricated container 10 when receiving the force is suppressed. As a result, a prefabricated container 10 is provided in which the deformation when receiving the force after assembly is suppressed.

[0058] In the assembled container 10 according to this embodiment, it is assumed that the one-end plate one-end-side protruding portion 102 is fitted into the one-side plate one-end-side concave portion 160. When a force in the direction in which it falls is applied to the one-end plate portion 74 in this state, the one-side support portion 182 and the other-side support portion 184 support both sides of the one-end plate one-end-side protruding portion 102. When a larger force is applied and the one-end plate one-end-side protruding portion 102 bends, the concave bottom portion 180 supports the central portion of the one-end plate one-end-side protruding portion 102. As a result, compared with the case where only the central portion of the one-end plate one-end-side protruding portion 102 is supported, the stress applied to the one-end plate one-end-side protruding portion 102 fitted into the one-side plate one-end-side concave portion 160 is suppressed. Since the stress is suppressed, the deformation of the one-end plate portion 74 having this is also suppressed.

[0059] In the assembled container 10 according to this embodiment, as the distance between the one-side support portion 182 and the other-side support portion 184 approaches the concave bottom portion 180, the one-end plate one-end-side protruding portion 102 fitted into the one-side plate one-end-side concave portion 160 becomes difficult to move. Since the one-end plate one-end-side protruding portion 102 becomes difficult to move, the deformation of the assembled container 10 due to its ease of movement is suppressed.

[0060] Further, in the assembled container 10 according to this embodiment, the trapezoidal one-end plate one-end-side protruding portion 102 is supported by the convex curved surface forming portion 202 of the one-side support portion 182 and the convex curved surface forming portion 202 of the other-side support portion 184. As a result, when a force is directly or indirectly applied such that the one-end plate one-end-side protruding portion 102 is pushed into the one-side plate one-end-side concave portion 160, a force that allows the one-end plate one-end-side protruding portion 102 to bend is applied thereto. When such a force is applied, the engagement between the one-side plate one-end-side concave portion 160 and the one-end plate one-end-side protruding portion 102 becomes firm.

[0061] Further, in the prefabricated container 10 according to the present embodiment, the range from the protruding end 120 of the one main body portion 100 of the end plate to the one end plate one - side protruding portion 102 is supported by the one connecting band 88. Thereby, when a force capable of tilting the one end plate portion 74 toward the bottom plate portion 78 is applied to that range, that force is also supported by the one connecting band 88. When that force is also supported by the one connecting band 88, a part of that force will narrow both ends of both the one side plate portion 70 and the other side plate portion 72. When those ends are narrowed, the one end plate one - side protruding portion 102 becomes difficult to come off from the one side plate one - side concave portion 160. For the same reason, the one end plate other - side protruding portion 104 becomes difficult to come off from the other side plate one - side concave portion 164, the other end plate one - side protruding portion 112 becomes difficult to come off from the one side plate other - side concave portion 162, and the other end plate other - side protruding portion 114 becomes difficult to come off from the other side plate other - side concave portion 166.

[0062] <Description of Modification Example> The embodiments disclosed this time are illustrative in all respects. The scope of the present invention is not limited based on the above - described embodiments, and of course, various design changes may be made without departing from the spirit of the present invention.

[0063] For example, the location where the one end plate one - side protruding portion 102 protrudes is not limited to near the center of one end of the one main body portion 100 of the end plate. That location may be a position different from the protruding end 124 of the one main body portion 100 of the end plate. As a result, the location where the one end plate one - side protruding portion 102 protrudes may be beside the one end plate connecting portion 80 among one end of the one main body portion 100 of the end plate, or may be a location slightly closer to the protruding end 124 than the center. Similarly, the location where the one end plate other - side protruding portion 104 protrudes is not limited to near the center of the other end of the one main body portion 100 of the end plate. That location may be a position different from the protruding end 124 of the one main body portion 100 of the end plate.

[0064] Further, the use of the prefabricated container according to the present invention is not limited to food storage. Any object can be stored in the prefabricated container according to the present invention.
