Description

[Technical Field]

[0001] The present specification relates to a container. [Background technology]

[0002] Conventionally, for example, a container has been provided with a cylindrical side wall portion, a bottom wall portion that is movable between a closed position that closes the bottom end opening of the side wall portion and an open position that opens the bottom end opening, and a connecting portion that connects the bottom wall portion to the side wall portion so that the bottom wall portion can rotate about an axis extending laterally relative to the side wall portion (for example, Patent Document 1). The connecting portion has a shaft portion that extends laterally.

[0003] In the container disclosed in Patent Document 1, the shaft of the connection part is disposed inside the side wall part in a vertical view, and therefore the gap between the side wall part and the bottom wall part is located inside the lower end opening of the side wall part in a vertical view. As a result, when contents contained inside the container are discharged from the lower end opening of the side wall part, the contents fall into the gap between the side wall part and the bottom wall part (for example, the connection part), and the contents accumulate or get stuck in the gap between the side wall part and the bottom wall part.

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0009] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] An embodiment of a container will be described below with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to help understand the configuration of the container, and is not intended to limit the configuration of the container.

[0011] In the following description, the first direction D1 is referred to as the first horizontal direction (also referred to as the "left-right direction") D1, the direction of the arrow in the drawing is referred to as the left direction, and the direction opposite to the arrow in the drawing is referred to as the right direction. The second direction D2 is referred to as the second horizontal direction (also referred to as the "front-rear direction") D2, the direction of the arrow in the drawing is referred to as the forward direction, and the direction opposite to the arrow in the drawing is referred to as the rearward direction.

[0012] Note that the terms "front, back, left, and right" are used for convenience of explanation, and of course, in the actual product, the front, back, left, and right may be reversed. Furthermore, the third direction D3 is referred to as the up-down direction D3, and the direction of the arrow in the figure is referred to as the up direction, and the direction opposite to the arrow in the figure is referred to as the down direction.

[0013] 1 to 3, the container 3 may be used, for example, in a drying device 1 that dries items (e.g., items that contain moisture, items that adhere to moisture, etc.) contained inside the container 3. Therefore, the container 3 according to this embodiment is also called a drying container 3.

[0014] The drying device 1 may include, for example, an apparatus main body 1a on which a container 3 is placed, as in the present embodiment. The apparatus main body 1a may include, for example, a base 2 on which the container 3 is placed, and an airflow generating device 4 connected to the base 2 and generating an airflow, as in the present embodiment. The device formed by the container 3 and the base 2 is also referred to as a container device 5.

[0015] For example, as in this embodiment, the airflow generation device 4 may include a main body 4a having a generation source (for example, a fan) that generates an airflow, and a connection pipe 4b (for example, a duct) that connects the main body 4a and the base 2. Alternatively, the airflow generation device 4 may be, for example, an air supply device that supplies gas to the base 2, as in this embodiment.

[0016] As a result, when the container 3 is placed on the base 2, the gas passes through the inside of the base 2 and then through the inside of the container 3. Therefore, when the container 3 is placed on the base 2, the gas passes through the inside of the base 2 and the inside of the container 3, so it is possible to dry the contents inside the container 3. The air supply device may be, for example, a blower that supplies outside air to the base 2, or may be, for example, an air conditioner that conditions (dehumidifies / humidifies, heats / cools) the outside air and supplies it to the base 2.

[0017] However, the configuration is not limited to this, and the airflow generation device 4 may be, for example, an exhaust device (air intake device) that exhausts gas from the base 2. As a result, when the container 3 is placed on the base 2, the gas passes through the inside of the container 3 and then the inside of the base 2. Therefore, when the container 3 is placed on the base 2, the gas passes through the inside of the base 2 and the inside of the container 3, and therefore the contents inside the container 3 can be dried.

[0018] The container 3 is detachable from the base 2, and can be separated from the base 2. Specifically, the container 3 is detached from the device main body 1a, whereby the portion that stores the contents (i.e., the container 3) can be separated from the drying device 1.

[0019] This allows, for example, the container 3 detached from the base 2 to be transported to a location other than the device main body 1a (base 2) or stored in a location other than the device main body 1a (base 2). Also, for example, after the contents inside the container 3 have been dried, the container 3 can be detached from the device main body 1a (base 2) and another container 3 can be attached to the device main body 1a (base 2), thereby allowing the contents inside the other container 3 to be dried using the common device main body 1a (base 2).

[0020] 2 and 3, the container 3 includes a cylindrical side wall portion 31 and a bottom wall portion 32 that covers a lower portion (specifically, a lower end opening 31g) of the side wall portion 31. For example, as in this embodiment, the bottom wall portion 32 may include a bottom plate 32b having a through hole 32a that opens to the inside of the container 3, and the side wall portion 31 may include an opening 31a that communicates with the through hole 32a via the internal space of the container 3 and opens to the inside of the container 3.

[0021] The lower surface of the bottom plate 32b may be exposed, for example, as in this embodiment. As a result, the through-holes 32a communicate the inside and outside of the container 3. The number of through-holes 32a is not particularly limited. For example, as in this embodiment, the through-holes 32a are preferably arranged evenly over the entire area of ​​the bottom plate 32b. As a result, gas can flow evenly throughout the entire interior of the container 3.

[0022] The side wall portion 31 may include, for example, a first side wall 31b and a second side wall 31c that face each other in the first horizontal direction D1, and a third side wall 31d and a fourth side wall 31e that face each other in the second horizontal direction D2, as in the present embodiment. That is, in the present embodiment, the side wall portion 31 is formed in a rectangular tubular shape. However, the present embodiment is not limited to this configuration, and the side wall portion 31 may be formed in, for example, a cylindrical shape.

[0023] The opening 31a may be arranged, for example, at the top of the container 3 so as to open the interior of the container 3 upward (i.e., to connect the interior and exterior of the container 3), as in this embodiment. In this embodiment, the opening 31a is configured as an opening at the upper end of the side wall portion 31. However, this is not limited to such a configuration, and the opening 31a may be arranged, for example, at the side of the side wall portion 31 so as to open the interior of the container 3 laterally.

[0024] The base 2 may include, for example, as in this embodiment, a communication port 21 that opens upward to the interior so as to communicate with the through-hole 32a of the container 3 when the container 3 is placed thereon, and a connection port 22 that is connected to the airflow generation device 4 (see FIG. 1 ) and communicates with the communication port 21 via the internal space. Note that the connection port 22 may be connected to the connection pipe 4b of the airflow generation device 4, for example, as in this embodiment. Furthermore, the communication port 21 communicates the interior of the base 2 with the outside, and the connection port 22 communicates the interior of the base 2 with the outside.

[0025] Furthermore, the base 2 may include, for example, as in the present embodiment, a base body 23 having the communication port 21 and the connection port 22, and a gas guide 24 that is disposed inside the base body 23 and guides the gas that has flowed in from the connection port 22. Note that, although not particularly limited, for example, as in the present embodiment, the base body 23 may include a cylindrical side wall portion and a bottom wall portion that covers the lower end opening of the side wall portion, and the communication hole 21 may be configured over the entire area of ​​the upper end opening of the side wall portion of the base body 23.

[0026] Since the underside of the bottom plate 32b of the container 3 is exposed, when the container 3 is placed on the base 2 of the device main body 1a, the inside of the device main body 1a communicates with the through hole 32a, and the through hole 32a communicates with the open port 31a via the internal space of the container 3, and the open port 31a opens to the inside of the container 3.

[0027] For example, in this embodiment, the connection port 22 of the base 2 communicates with the communication port 21 of the base 2 via the internal space of the base 2, the communication port 21 of the base 2 communicates with the through hole 32a of the container 3, the through hole 32a of the container 3 communicates with the open port 31a of the container 3 via the internal space of the container 3, and the open port 31a of the container 3 opens to the inside of the container 3.

[0028] As a result, the airflow generated by the airflow generation device 4 flows through the connection port 22 and the communication port 21 of the base 2, and the through-hole 32a and the open port 31a of the container 3. Therefore, since the airflow passes through the inside of the container 3, the contents inside the container 3 can be dried.

[0029] Furthermore, for example, as in the present embodiment, the base 2 may be configured to include an annular mounting portion 25 on which the container 3 is placed, and the container 3 may be configured to include an annular abutment portion 32c that contacts the mounting portion 25 when placed on the base 2. For example, as in the present embodiment, the mounting portion 25 may protrude outward in the lateral directions D1 and D2 in a flange-like manner from the upper end of the base body 23. For example, as in the present embodiment, the abutment portion 32c may be configured at the lower end of the bottom wall portion 32 of the container 3.

[0030] As a result, when the container 3 is placed on the base 2, the contact portion 32c of the container 3 contacts the entire periphery of the mounting portion 25 of the base 2. This prevents a gap from being formed between the container 3 and the base 2, thereby preventing gas from leaking between the container 3 and the base 2, for example.

[0031] For example, as in the present embodiment, the bottom wall 32 may include an annular frame 32d that supports the outer periphery of the bottom plate 32b from below, and the abutment portion 32c may be formed by the lower surface of the frame 32d. Note that the bottom wall 32 may include a bottom main body 32e that covers the lower end opening 31g of the side wall 31, and the bottom main body 32e may be formed by the bottom plate 32b and the frame 32d, for example, as in the present embodiment.

[0032] The contact portion 32c may be formed in a continuous ring shape, i.e., an endless ring shape, as in the present embodiment. The lower surface of the contact portion 32c, i.e., the surface that contacts the mounting portion 25, may be formed as a flat surface, as in the present embodiment.

[0033] The mounting portion 25 may be formed in a continuous ring shape, i.e., an endless ring shape, as in the present embodiment. The upper surface of the mounting portion 25, i.e., the surface that contacts the contact portion 32c, may be formed as a flat surface, as in the present embodiment.

[0034] 3 and 4, the container 3 may include, for example, a hook portion 33 fixed to the upper end of the side wall portion 31 (specifically, the third side wall 31d and the fourth side wall 31e). This allows the container 3 to be raised, lowered, or tilted by, for example, hooking a forklift, a chain block, a wire, or the like onto the hook portion 33.

[0035] The container 3 includes a connection portion 34 that rotatably connects the bottom wall portion 32 to the side wall portion 31 around an axis in the first horizontal direction D1. This allows the bottom wall portion 32 to move between a closed position (position shown in FIGS. 3 and 4) where the bottom wall portion 32 closes the bottom end opening 31g of the side wall portion 31, and an open position (position shown in FIGS. 7 to 9) where the bottom end opening 31g of the side wall portion 31 is open.

[0036] The number of connecting portions 34 is not particularly limited, and may be, for example, a plurality (five in FIG. 3) as in this embodiment, or may be, for example, one. Furthermore, in this specification, unless otherwise specified, the positional relationship of each portion (for example, the positional relationship in each direction D1 to D3) is the relationship when the container 3 is placed independently on a horizontal plane and the bottom wall portion 32 is in the closed position.

[0037] 4 and 5, the connecting portion 34 includes a shaft portion 34a extending in the first horizontal direction D1, a sidewall fixing portion 34b fixed to the sidewall portion 31, and a bottom wall fixing portion 34c fixed to the bottom wall portion 32 and rotatably connected to the sidewall fixing portion 34b by the shaft portion 34a. This allows the bottom wall portion 32 to rotate about the shaft portion 34a between the closed position and the open position. That is, the bottom wall portion 32 can rotate about the first horizontal direction D1 between the closed position and the open position.

[0038] For example, as in this embodiment, the side wall fixing portion 34b may be fixed to the outer peripheral surface of the side wall portion 31 (specifically, the outer surface of the third side wall 31d) and may protrude outward in the second lateral direction D2 from the outer peripheral surface of the side wall portion 31 (specifically, the outer surface of the third side wall 31d). As a result, the shaft portion 34a is disposed outward in the second lateral direction D2 from the outer peripheral surface of the side wall portion 31.

[0039] Also, for example, as in the present embodiment, the bottom wall fixing portion 34c may be fixed to the base end portion 32f of the bottom wall portion 32 in the second horizontal direction D2 (specifically, the base end portion 32f of the bottom main body portion 32e in the second horizontal direction D2) and may protrude upward from the base end portion 32f of the bottom wall portion 32 (the base end portion 32f of the bottom main body portion 32e). As a result, the shaft portion 34a is disposed above the upper end of the bottom wall portion 32.

[0040] For example, the side wall fixing portion 34b and the bottom wall fixing portion 34c may each be rotatably connected to the shaft portion 34a, or for example, the side wall fixing portion 34b may be fixed to the shaft portion 34a and the bottom wall fixing portion 34c may be rotatably connected to the shaft portion 34a, or for example, the bottom wall fixing portion 34c may be fixed to the shaft portion 34a and the side wall fixing portion 34b may be rotatably connected to the shaft portion 34a.

[0041] That is, the shaft portion 34a is rotatably connected to at least one of the side wall fixing portion 34b and the bottom wall fixing portion 34c. The shaft portion 34a may be formed, for example, in a columnar shape, or may be formed, for example, in a cylindrical shape.

[0042] 4 and 6, the side wall 31 and the bottom wall 32 have hook portions 31f, 32g that can be switched between a state in which they are hooked to each other and a state in which they are released from the hooking. The hook portion 31f of the side wall 31 is referred to as the side wall hook portion 31f, and the hook portion 32g of the bottom wall 32 is referred to as the bottom wall hook portion 32g.

[0043] When the hook portions 31f and 32g are hooked to each other (see FIGS. 4 and 6), the bottom wall portion 32 is held in the closed position. On the other hand, when the hook portions 31f and 32g are released from the hooking (see FIGS. 7 and 8), the bottom wall portion 32 is movable between the closed position and the open position.

[0044] 4 to 6, the bottom wall 32 includes a first roller 32h rotatably connected to the bottom main body 32e, and a second roller 32i rotatably connected to the bottom main body 32e and separate from the first roller 32h. The bottom wall 32 may also include legs 32j extending downward from the bottom main body 32e, as in this embodiment.

[0045] The number of first rollers 32h is not particularly limited, and may be, for example, a plurality of first rollers 32h arranged in the first horizontal direction D1 as in this embodiment, or may be, for example, one. The number of second rollers 32i is not particularly limited, and may be, for example, a plurality of second rollers 32i arranged in the first horizontal direction D1 as in this embodiment, or may be, for example, one. The number of legs 32j is not particularly limited, and may be, for example, a plurality of second rollers 32i arranged in the first horizontal direction D1 as in this embodiment, or may be, for example, one.

[0046] The bottom wall 32 may include, for example, a first journal 32k extending downward from the bottom body 32e and rotatably supporting the first roller 32h, as in the present embodiment. As a result, when the bottom wall 32 is in the closed position, the first roller 32h is positioned lower than the bottom body 32e, and therefore the first roller 32h comes into contact with the ground.

[0047] For example, in the present embodiment, the first roller 32h and the legs 32j are in contact with the ground, and therefore the container 3 is supported by the first roller 32h and the legs 32j. Note that, for example, as in the present embodiment, the first roller 32h (first pivot support portion 32k) may be connected to the tip end portion 32m side of the center of the bottom main body portion 32e in the second horizontal direction D2, and the legs 32j may be connected to the base end portion 32f side of the center of the bottom main body portion 32e in the second horizontal direction D2.

[0048] Furthermore, the first roller 32h may be rotatable about an axis in the first horizontal direction D1, as in the present embodiment. This allows the container 3 to be moved while the first roller 32h rolls on the ground by, for example, lifting the hook portion 33 fixed on the third side wall 31d, tilting the container 3, and lifting the legs 32j off the ground. This allows the container 3 to be moved smoothly.

[0049] The bottom wall 32 may also include a second journal support 32n extending from the tip 32m of the bottom main body 32e in the second horizontal direction D2 and rotatably supporting the second roller 32i, as in the present embodiment. As a result, the second roller 32i is disposed farther from the shaft 34a of the connecting portion 34 than the tip 32m of the bottom main body 32e when viewed in the first horizontal direction D1. Note that the second roller 32i may be rotatable about an axis in the first horizontal direction D1, as in the present embodiment.

[0050] The entire bottom wall portion 32 is disposed above an imaginary line X1 tangent to the first roller 32h and the second roller 32i as viewed in the first horizontal direction D1. In this embodiment, the imaginary line X1 is a common tangent to the first roller 32h and the second roller 32i as viewed in the first horizontal direction D1. This prevents other portions of the bottom wall portion 32 (for example, the bottom main body portion 32e) from hitting the ground when at least one of the first roller 32h and the second roller 32i hits the ground.

[0051] 7, when the lower end of the first roller 32h is positioned lower than the lower end of the second roller 32i, the lower end of the first roller 32h is at the lowest position of the bottom wall portion 32. As a result, the first roller 32h comes into contact with the ground, and therefore, for example, the lower end (contact portion 32c) of the bottom main body portion 32e does not come into contact with the ground.

[0052] 8, when the lower end of the first roller 32h and the lower end of the second roller 32i are positioned at the same height, the lower ends of the rollers 32h, 32i are at the lowest position of the bottom wall portion 32. As a result, the first roller 32h and the second roller 32i come into contact with the ground, so that, for example, the lower end (contact portion 32c) and the tip portion 32m of the bottom main body portion 32e do not come into contact with the ground.

[0053] 9, when the lower end of the second roller 32i is positioned lower than the lower end of the first roller 32h, the lower end of the second roller 32i is at the lowest position of the bottom wall portion 32. As a result, the second roller 32i comes into contact with the ground, and therefore, for example, the tip portion 32m of the bottom main body portion 32e does not come into contact with the ground.

[0054] In this embodiment, the bottom main body portion 32e and the rollers 32h, 32i are rotatable about an axis in the first horizontal direction D1, and the rollers 32h, 32i are connected to the bottom main body portion 32e. As a result, for example, the bottom wall portion 32 can be rotated and moved by raising or lowering the container 3 so that the rollers 32h, 32i come into contact with the ground and roll on the ground.

[0055] For example, when the container 3 is raised so that the rollers 32h, 32i contact the ground and roll on the ground, the bottom wall 32 rotates from the closed position to the open position. Also, when the container 3 is lowered so that the rollers 32h, 32i contact the ground and roll on the ground, the bottom wall 32 rotates from the open position to the closed position.

[0056] 9, when the bottom wall portion 32 is in the open position where it is balanced by its own weight, the center of gravity 32p of the bottom wall portion 32 is located directly below the center of the shaft portion 34a of the connecting portion 34 when viewed in the first lateral direction D1. While the center of gravity 32p of the bottom wall portion 32 is located between the upper and lower ends of the bottom wall portion 32, when the bottom wall portion 32 is in the closed position, the shaft portion 34a of the connecting portion 34 is located above the bottom wall portion 32 (see FIGS. 4 to 6).

[0057] As a result, when the bottom wall portion 32 is in the open position where it is balanced by its own weight, the second roller 32i, which is the tip of the bottom wall portion 32, is positioned inward in the second lateral direction D2 from the shaft portion 34a of the connection portion 34. Therefore, for example, when the container 3 is lowered from this state, the second roller 32i comes into contact with the ground and rolls on the ground, causing the bottom wall portion 32 to rotate toward the closed position. Therefore, for example, the bottom wall portion 32 can be smoothly moved from the open position to the closed position.

[0058] 4 and 5, when the bottom wall portion 32 is in the closed position, the base end 32q of the bottom wall portion 32 is disposed outward in the second lateral direction D2 from the lower end opening 31g of the side wall portion 31. Since the shaft portion 34a of the connecting portion 34 is disposed outward in the second lateral direction D2 from the side wall portion 31, the shaft portion 34a of the connecting portion 34 is disposed outside the side wall portion 31 when viewed in the up-down direction D3.

[0059] 7 to 9, when the bottom wall portion 32 is rotated from the closed position to the open position, the base end 32q of the bottom wall portion 32 is disposed outward in the second lateral direction D2 from the side wall portion 31. Specifically, when the bottom wall portion 32 is disposed in the open position or the closed position, the base end 32q of the bottom wall portion 32 is disposed outward in the second lateral direction D2 from the lower end opening 31g of the side wall portion 31. More specifically, when the bottom wall portion 32 is disposed in the open position or the closed position, the base end 32q of the bottom wall portion 32 is disposed outside the lower end opening 31g of the side wall portion 31 when viewed in the up-down direction D3.

[0060] Therefore, when the bottom wall 32 is in the open position, the gap between the side wall 31 and the bottom wall 32 is located outward from the lower end opening 31g of the side wall 31, and therefore, when viewed in the up-down direction D3, the gap between the side wall 31 and the bottom wall 32 is located outside the lower end opening 31g of the side wall 31. Therefore, when the contents are discharged from the lower end opening 31g of the side wall 31, the contents can be prevented from falling into the gap between the side wall 31 and the bottom wall 32, and therefore, for example, the contents can be prevented from accumulating or clogging in the gap between the side wall 31 and the bottom wall 32.

[0061] [1] As described above, the container 3, as in this embodiment, A cylindrical side wall portion 31; a bottom wall portion 32 movable between a closed position that closes a lower end opening 31g of the side wall portion 31 and an open position that opens the lower end opening 31g; a connecting portion 34 connecting the side wall portion 31 and a base end portion 32f of the bottom wall portion 32 in a second horizontal direction D2 perpendicular to the first horizontal direction D1 so that the bottom wall portion 32 can rotate about an axis of a first horizontal direction D1 between the closed position and the open position, A base end 32q of the bottom wall portion 32 in the second lateral direction D2 is disposed outward in the second lateral direction D2 from the lower end opening 31g of the side wall portion 31 when the bottom wall portion 32 is positioned at the closed position and the open position. This configuration is preferred.

[0062] With this configuration, the connecting portion 34 connects the base end portion 32f of the bottom wall portion 32 to the side wall portion 31, so that the bottom wall portion 32 rotates between the closed position and the open position around an axis in the first horizontal direction D1. When the bottom wall portion 32 is in the closed position or the open position, the base end 32q of the bottom wall portion 32 in the second horizontal direction D2 is positioned outward in the second horizontal direction D2 from the lower end opening 31g of the side wall portion 31. As a result, the gap between the side wall portion 31 and the bottom wall portion 32 is positioned outward from the lower end opening 31g of the side wall portion 31, so that contents can be prevented from falling into the gap between the side wall portion 31 and the bottom wall portion 32.

[0063] [2] In addition, in the container 3 of [1] above, as in this embodiment, The connection portion 34 is a shaft portion 34a extending in the first horizontal direction D1; a side wall fixing portion 34b fixed to the side wall portion 31; a bottom wall fixing portion 34c fixed to the base end portion 32f of the bottom wall portion 32 and rotatably connected to the side wall fixing portion 34b by the shaft portion 34a, The shaft portion 34a is disposed outward in the second lateral direction D2 from the side wall portion 31. This configuration is preferred.

[0064] According to this configuration, the side wall fixing portion 34b fixed to the side wall portion 31 and the bottom wall fixing portion 34c fixed to the base end portion 32f of the bottom wall portion 32 are rotatably connected by the shaft portion 34a. As a result, the bottom wall portion 32 rotates about the shaft portion 34a, and therefore the bottom wall portion 32 rotates about the first horizontal direction D1.

[0065] The shaft portion 34a is disposed outward in the second lateral direction D1 from the side wall portion 31. As a result, if the base end 32q of the bottom wall portion 32 is disposed outward in the second lateral direction D2 from the lower end opening 31g of the side wall portion 31 when the bottom wall portion 32 is in the closed position, the base end 32q of the bottom wall portion 32 is disposed outward in the second lateral direction D2 from the lower end opening 31g of the side wall portion 31 when the bottom wall portion 32 is in the open position.

[0066] [3] In addition, in the container 3 of [2] above, as in this embodiment, The shaft portion 34a is disposed above the bottom wall portion 32. This configuration is preferred.

[0067] According to this configuration, when the bottom wall portion 32 is in the closed position, the shaft portion 34a is disposed higher than the bottom wall portion 32. When the bottom wall portion 32 is in the open position where it is balanced by its own weight, the center of gravity 32p of the bottom wall portion 32 is located directly below the center of the shaft portion 34a when viewed in the first horizontal direction D1, and therefore the tip portion of the bottom wall portion 32 is likely to be disposed more inward in the second horizontal direction D2 than the shaft portion 34a.

[0068] [4] In addition, in any one of the containers 3 described above in [1] to [3], as in this embodiment, The bottom wall portion 32 is a bottom body portion 32e that covers the lower end opening 31g of the side wall portion 31 and is connected to the connecting portion 34 at a base end portion 32f in the second horizontal direction D2; a first roller 32h disposed below the bottom body portion 32e and connected to the bottom body portion 32e so as to be grounded; This configuration is preferable.

[0069] According to this configuration, when the bottom wall portion 32e is in the closed position, the first roller 32h is disposed below the bottom main body portion 32e and therefore comes into contact with the ground. Furthermore, since the first roller 32h is connected to the bottom main body portion 32e, the bottom wall portion 32 can be rotated by raising or lowering the container 3 so that the first roller 32h comes into contact with the ground and rolls on the ground.

[0070] [5] In addition, in any one of the containers 3 described above in [1] to [4], as in this embodiment, The bottom wall portion 32 includes a second roller 32i connected to the bottom body portion 32e, The second roller 32i is disposed farther from the shaft portion 34a than the tip end 32m of the bottom main body portion 32e in the second horizontal direction D2 when viewed in the first horizontal direction D1. This configuration is preferable.

[0071] With this configuration, the second roller 32i is farther from the shaft 34a of the connecting portion 34 than the tip 32m of the bottom main body portion 32e when viewed in the first lateral direction D1, and therefore the second roller 32i is likely to be located lower than the tip 32m of the bottom main body portion 32e when the bottom wall portion 32 is in the open position. This makes it possible to prevent the tip 32m of the bottom main body portion 32e from hitting the ground.

[0072] [6] In addition, in the container 3 having the configurations [4] and [5] above, as in this embodiment, The entire bottom wall portion 32 is disposed above an imaginary line X1 that contacts the first roller 32h and the second roller 32i when viewed in the first lateral direction D1. This configuration is preferable.

[0073] According to this configuration, the entire bottom wall portion 32 is positioned above the imaginary line X1 that contacts the first roller 32h and the second roller 32i when viewed in the first horizontal direction D1, so that when at least one of the first roller 32h and the second roller 32i comes into contact with the ground, it is possible to prevent other portions of the bottom wall portion 32 from coming into contact with the ground.

[0074] The container 3 is not limited to the configuration of the embodiment described above, nor is it limited to the effects and advantages described above. Furthermore, various modifications can be made to the container 3 without departing from the spirit of the present invention. For example, it is possible to arbitrarily select one or more of the configurations, methods, etc. of the various modified examples described below and adopt them in the configurations, methods, etc. of the embodiment described above.

[0075] (A) In the container 3 according to the above embodiment, one container 3 is placed on one base 2. However, the container 3 is not limited to such a configuration. For example, multiple containers 3 may be placed on one base 2. An example of such a configuration may be the configuration shown in FIG. 10 or FIG. 11.

[0076] (A-1) As shown in Fig. 10, for example, a configuration may be adopted in which a plurality of containers 3 (two in Fig. 10) are directly placed on a single base 2. This allows, for example, gas to pass through the interior of the base 2 and then through the interiors of each of the containers 3, 3. The number of containers 3 directly placed on a single base 2 is not particularly limited, and may be, for example, one as in the above embodiment, or may be, for example, two as shown in Fig. 10, or may be, for example, three or more.

[0077] (A-2) Also, as shown in Fig. 11, for example, a configuration may be adopted in which a first container 3 is placed on a second container 3, and the second container 3 is placed on a base 2. This allows, for example, gas to pass through the interior of the base 2, the interior of the second container 3, and the interior of the first container 3 in that order. Note that the number of containers 3 stacked in the vertical direction D3 is not particularly limited, and may be, for example, one as in the above embodiment, or may be, for example, two as shown in Fig. 11, or may be, for example, three or more.

[0078] (A-3) Although not shown, for example, multiple containers 3 may be directly placed on one base 2 in a row in the horizontal directions D1 and D2, and multiple containers 3 may be stacked in the vertical direction D3.

[0079] (B) Furthermore, the container 3 according to the above embodiment is configured such that there is only one bottom wall portion 32 covering the lower end opening 31g of the side wall portion 31. However, the container 3 is not limited to this configuration.

[0080] For example, as shown in Fig. 12, a configuration may be adopted in which there are a plurality of bottom wall portions 32 covering the lower end opening 31g of the side wall portion 31. The number of bottom wall portions 32 covering the lower end opening 31g of the side wall portion 31 is not particularly limited, and may be, for example, one as in the above embodiment, or may be, for example, two as shown in Fig. 12, or may be, for example, three or more.

[0081] (C) In addition, in the container 3 according to the above embodiment, the bottom plate 32b of the bottom wall portion 32 has the through-hole 32a, and the lower surface of the bottom plate 32b is exposed. That is, the container 3 is configured as a drying container 3 used in the drying device 1. However, the container 3 is not limited to this configuration.

[0082] For example, the bottom plate 32b of the bottom wall portion 32 may not have the through-hole 32a. That is, the container 3 may be a container 3 used for purposes other than the drying device 1. Also, for example, the lower surface of the bottom plate 32b of the bottom wall portion 32 may be covered by another member and not exposed.

[0083] (D) Furthermore, in the container 3 according to the above embodiment, the shaft portion 34a of the connection portion 34 is configured to be located above the bottom wall portion 32. However, the container 3 is not limited to this configuration. For example, the shaft portion 34a of the connection portion 34 may be configured to be located below the bottom wall portion 32.

[0084] (E) In the container 3 according to the above embodiment, the bottom wall 32 includes a first roller 32h disposed below the bottom main body 32e and legs 32j extending downward from the bottom main body 32e, and the first roller 32h and legs 32j are in contact with the ground. However, the container 3 is not limited to this configuration.

[0085] For example, the bottom wall portion 32 may be configured to include the first roller 32h but not the legs 32j, with the first roller 32h in contact with the ground. Alternatively, for example, the bottom wall portion 32 may be configured to include the legs 32j but not the first roller 32h, with the legs 32j in contact with the ground. Alternatively, for example, the bottom wall portion 32 may be configured to include the first roller 32h and the legs 32j, with the bottom main body portion 32e in contact with the ground.

[0086] (F) In the container 3 according to the above embodiment, the bottom wall portion 32 includes the first roller 32h disposed below the bottom main body portion 32e to contact the ground, and the second roller 32i disposed farther from the shaft portion 34a than the tip end 32m of the bottom main body portion 32e as viewed in the first lateral direction D1. However, the container 3 is not limited to this configuration.

[0087] For example, the bottom wall portion 32 may be configured to include the first roller 32h but not the second roller 32i. Alternatively, the bottom wall portion 32 may be configured to include the second roller 32i but not the first roller 32h. Alternatively, the bottom wall portion 32 may be configured to include neither the first roller 32h nor the second roller 32i.

[0088] (G) In the container 3 according to the above embodiment, the first roller 32h is separate from the second roller 32i. However, the container 3 is not limited to this configuration.

[0089] For example, the first roller 32h may be common to the second roller 32i, i.e., the first roller 32h may also serve as the second roller 32i. In such a configuration, the common roller 32h (32i) is connected to the bottom main body portion 32e, is disposed below the bottom main body portion 32e to be grounded, and is disposed farther from the shaft portion 34a than the tip end 32m of the bottom main body portion 32e as viewed in the first lateral direction D1.

[0090] (H) In addition, in the container 3 according to the above embodiment, the bottom wall portion 32 (bottom main body portion 32e) is rotatable about an axis in the first horizontal direction D1, and the first roller 32h and the second roller 32i are each rotatable about an axis in the same first horizontal direction D1. However, the container 3 is not limited to such a configuration.

[0091] For example, the bottom wall 32 (bottom main body 32e) may be rotatable about an axis in the first horizontal direction D1, while the first roller 32h may be rotatable about an axis in a horizontal direction different from the first horizontal direction D1 (for example, a second horizontal direction D2). Also, for example, the bottom wall 32 (bottom main body 32e) may be rotatable about an axis in the first horizontal direction D1, while the second roller 32i may be rotatable about an axis in a horizontal direction different from the first horizontal direction D1 (for example, the second horizontal direction D2).

[0092] Alternatively, for example, the first roller 32h may be configured to be rotatable about an axis in the first horizontal direction D1, while the second roller 32i may be configured to be rotatable about an axis in a horizontal direction different from the first horizontal direction D1 (for example, a second horizontal direction D2). Alternatively, for example, the second roller 32i may be configured to be rotatable about an axis in the first horizontal direction D1, while the first roller 32h may be configured to be rotatable about an axis in a horizontal direction different from the first horizontal direction D1 (for example, a second horizontal direction D2).

[0093] (I) Furthermore, in the container 3 according to the above embodiment, the second roller 32i is configured to be off the ground when the bottom wall 32 is in the closed position and the container 3 touches the ground. However, the container 3 is not limited to this configuration. For example, the container 3 may be configured such that the second roller 32i touches the ground when the bottom wall 32 is in the closed position and the container 3 touches the ground.

[0094] (J) In addition, in the container 3 according to the above embodiment, the entire bottom wall portion 32 is configured to be located above the imaginary line X1 tangent to the first roller 32h and the second roller 32i when viewed in the first horizontal direction D1. However, the container 3 is not limited to this configuration. For example, a portion of the bottom wall portion 32 may be configured to be located below the imaginary line X1 tangent to the first roller 32h and the second roller 32i when viewed in the first horizontal direction D1.

[0095] (K) In addition, in the container 3 according to the above embodiment, the center of gravity 32p of the bottom wall portion 32 is located at a position overlapping with the bottom main body portion 32e when viewed in the first lateral direction D1, i.e., located between the upper end (bottom plate 32b) and the lower end (contact portion 32c) of the bottom main body portion 32e. However, the container 3 is not limited to this configuration.

[0096] For example, the center of gravity 32p of the bottom wall portion 32 may be located below the lower end (contact portion 32c) of the bottom main body portion 32e as viewed in the first lateral direction D1. An example of such a configuration may be the configuration shown in FIG.

[0097] In the container 3 shown in Fig. 13, the second roller 32i is disposed below the bottom main body portion 32e. This allows the center of gravity 32p of the bottom wall portion 32 to be lowered. However, this configuration is not limited thereto, and the center of gravity 32p of the bottom wall portion 32 can be lowered by, for example, increasing the weight of the leg 32j or the weight of the first roller 32h or the first pivot support portion 32k.

[0098] (L) In the container 3 according to the above embodiment, the connecting portion 34 is configured to include the shaft portion 34a rotatably connected to at least one of the side wall fastening portion 34b and the bottom wall fastening portion 34c. However, the container 3 is not limited to this configuration. For example, the connecting portion 34 may not include the shaft portion 34a rotatably connected to at least one of the side wall fastening portion 34b and the bottom wall fastening portion 34c, but the bottom wall portion 32 may be configured to be rotatable about the axis of the first horizontal direction D1 by the connecting portion 34 between the closed position and the open position.

[0099] Specifically, the connecting portion 34 may be configured to include an elastic portion that is fixed to the side wall fixing portion 34b and the bottom wall fixing portion 34c. Although not particularly limited, examples of such a configuration may include the configuration shown in Fig. 14 or the configuration shown in Fig. 15.

[0100] (L-1) The connecting portion 34 shown in Fig. 14 includes an elastic portion 34f fixed to the side wall fixing portion 34b and the bottom wall fixing portion 34c. The elastic portion 34f extends in the first horizontal direction D1, with a first end portion of the elastic portion 34f fixed to the side wall fixing portion 34b and a second end portion of the elastic portion 34f fixed to the bottom wall fixing portion 34c. The elastic portion 34f is formed to be elastically deformable so as to twist. In other words, the elastic portion 34f is a so-called torsion bar.

[0101] As a result, the elastic portion 34f is elastically deformed in a twisting manner, causing the bottom wall portion 32 to rotate about the first horizontal direction D1 as an axis between the closed position and the open position, as shown in Fig. 14(b). Note that in the configuration shown in Fig. 14, the elastic deformation of the elastic portion 34f may cause the rotation axis of the bottom wall portion 32 to change slightly when the bottom wall portion 32 rotates.

[0102] (L-2) The connecting portion 34 shown in Fig. 15 includes an elastic portion 34f fixed to the side wall fixing portion 34b and the bottom wall fixing portion 34c. The ends of the elastic portion 34f extend linearly, and the middle portion of the elastic portion 34f is formed in a coil shape. The elastic portion 34f is formed to be elastically deformable in a twisting manner. In other words, the elastic portion 34f is a so-called torsion coil spring.

[0103] As a result, the elastic portion 34f is elastically deformed in a twisting manner, causing the bottom wall portion 32 to rotate about the first horizontal direction D1 as an axis between the closed position and the open position, as shown in Fig. 15(b). Note that in the configuration shown in Fig. 15, the elastic deformation of the elastic portion 34f may cause the rotation axis of the bottom wall portion 32 to change slightly when the bottom wall portion 32 rotates.

[0104] (M) For example, the container 3 may also be provided with a restricting portion that restricts the bottom wall portion 32 from rotating in a direction away from the closed position. Although not particularly limited, an example of such a configuration may be the configuration shown in FIG. 16.

[0105] 16, the container 3 is provided with a restricting portion 35 that restricts the bottom wall portion 32 from rotating in a direction away from the closed position. The side wall fixing portion 34b and the bottom wall fixing portion 34c of the connecting portion 34 may be provided with abutment stop portions 34d, 34e that abut against and stop against each other, and the restricting portion 35 may be configured as the abutment stop portions 34d, 34e.

[0106] As a result, the center of gravity 32p of the bottom wall portion 32 is positioned further inward in the second lateral direction D2 than the center of the shaft portion 34a of the connecting portion 34. Therefore, compared to when the bottom wall portion 32 is in the open position where it is balanced by its own weight, the second roller 32i, which is the tip of the bottom wall portion 32, is positioned further inward in the second lateral direction D2. Therefore, for example, the bottom wall portion 32 can be moved more smoothly from the open position to the closed position.

[0107] In addition, the abutment stop portion constituting the regulating portion 35 may be provided, for example, on the side wall fixing portion 34b and the bottom wall portion 32, or may be provided, for example, on the side wall portion 31 and the bottom wall fixing portion 34c, or may be provided, for example, on the side wall portion 31 and the bottom wall portion 32.

[0108] (N) For example, the container 3 may also have a reinforcing portion for reinforcing the side walls 31b to 31e inside the side wall portion 31. Although not particularly limited, an example of such a configuration may be the configuration shown in FIG.

[0109] The container 3 shown in Fig. 17 includes reinforcing portions 36, 37 that reinforce the side walls 31b to 31e. The reinforcing portions 36, 37 include a first reinforcing portion 36 that reinforces the adjacent side walls 31b, 31d (31b, 31e; 31c, 31d; 31c, 31e) by fixing them together, and a second reinforcing portion 37 that extends along the lateral direction D1 (D2) and is fixed to the side walls 31b to 31e to reinforce them.

[0110] 17(b), when viewed in the up-down direction D3, the lower end opening 31g is an opening formed by the first reinforcing portion 36 and the second reinforcing portion 37. In this way, the lower end opening 31g is an opening through which the contents contained therein are discharged.

[0111] (O) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
