Description

Plate-shaped container for transporting

The present invention relates to a container for transporting, and is used for transporting and storing various glass substrates such as a glass plate for a glass plate, a liquid crystal display, or a plasma display, or a touch panel. The panel and other plate-shaped bodies, and in particular, a container for transporting a plate-shaped body.

In the past, it has been used as a transport container for storing and transporting various glass substrates such as a glass plate for a raw plate glass or a glass substrate for liquid crystal display, a panel such as a solar cell panel or a touch panel, and other non-impact plate-like bodies. In general, the following container is used, which is a container including a container body and a lid body having a cushioning synthetic resin foaming system, and is disposed in a vertical groove which is juxtaposed at equal intervals on the inner surface of one of the opposing side walls of the container body. The plate-like bodies are inserted piece by piece, and the plate-like bodies are supported and housed in an upright state without being in contact with each other.

In recent years, as the demand for the increase in the size of liquid crystal televisions or plasma televisions has increased, even glass substrates for televisions have been used for transporting large or small glass substrates having a length of one or more than 100 cm. The container for transporting the glass substrate is also increased in size.

However, in the conventional method of accommodating the glass substrate in the upright state through the vertical groove on the inner surface of the side wall, since the glass substrate is large and heavy, the glass substrate itself may be bent and deformed by its own weight, or may be due to the glass substrate. The weight is concentrated on the bottom of the container body, causing compression deformation at the bottom of the container, thereby impairing the cushion function or the shock mitigation function.

In order to avoid this problem, as exemplified in Patent Document 1 to Patent Document 3, the following transfer container has been formed in which the glass substrate and the protective sheet are alternately overlapped in the container body. The horizontal state is accommodated, and each glass substrate is supported by the surface via a protective sheet.

In the case of a container for transporting a plate-shaped body such as a glass substrate in a horizontal state as described above, particularly, the corner portion of the peripheral edge of the plate-shaped body to be accommodated is easily affected by vibration or impact during transportation. There is a possibility that damage may occur due to contact with the bottom surface of the container body or the inner surface of the side wall.

Therefore, various designs have been made by those skilled in the art. For example, in Patent Document 1, in a box for transporting a glass substrate, the inner circumference of the side wall of the box body (container body) is provided to include flexibility. The abutting member of the synthetic resin foam abuts the peripheral edge of the glass substrate to the abutting member, and the side or corner portion of the peripheral edge is not directly in contact with the inner surface of the side wall to face the surface of the glass substrate during transportation. The vibrations to mitigate the impact to protect.

Further, in the case of Patent Document 2, in the transfer case for the glass substrate, in order to protect the accommodated glass substrate, a slit space is formed at the four corners of the main body to prevent the corner portion of the accommodated glass substrate from contacting the case body. a corner portion is formed with a groove groove at intervals on the inner surface of the side wall of the body, thereby preventing each side of the peripheral edge of the glass substrate from covering the inner surface of the side wall over the entire length, and further including the four corners of the inner bottom surface The peripheral portion forms a groove groove to prevent the end edge of the glass substrate from contacting the inner bottom surface.

Further, in the case of Patent Document 3, a groove is formed in the peripheral portion of the bottom surface of the main body to prevent the peripheral edge of the plate-like body from contacting the bottom surface, and a contact member for cushioning is disposed on the inner surface of the side wall to make a glass substrate or the like. The peripheral edge of the plate-like body abuts against the abutting member, thereby preventing each side or corner portion of the peripheral edge of the plate-like body from directly contacting the inner surface of the side wall.

However, in either case, the crack prevention is not sufficiently satisfied, and the crack is caused by vibration in the conveyance or conveyance operation or deformation of the container body due to a drop impact on the side portion or the like. .

This point is explained. For example, as shown in FIG. 16, a cutout portion 117 is formed in the following container, that is, inside the side wall of the four corner portions of the container body 101, and is provided at the peripheral portion of the upper surface 113a of the bottom portion 113, including In the container in which the notch portion 117 is continuous over the entire circumference, the concave portion 115 is continuous to prevent the corner portion or the peripheral edge of the plate-like body B from being in contact with the bottom surface, and the bottom surface 115a and the side wall 114 of the concave portion 115 are formed. When the boundary portion of the inner surface is continuous and intersected at right angles with almost no R curve, the plate-like body B is stored and packed as shown in FIG. The load of the plate-shaped body B as the storage object acts on the side wall 114 due to the fall from the side portion, etc., and the side wall 114 is intended to be deformed outward as shown, for example, in FIG. 18(a), and stress is concentrated on the concave portion. The bottom surface 115a of 115 and the boundary portion 116 on the inner surface of the side wall 114 are sheared, and the crack C shown in Fig. 18(b) is generated. If the force is reversed, damage may occur, and thus there is a problem in durability.

In order to solve the above problems, the present invention provides a container for transporting a plate-like body, which is used as a plate-like body for accommodating a glass substrate, a solar cell panel, a touch panel, or the like in a flat state, and is transported. The container for transporting the plate-shaped body can improve the protection of the peripheral portion of the plate-shaped body to be stored, and the side wall of the container body can be subjected to strong force even by vibration or drop impact during transportation or transportation work. In the case of deformation to the outside, it is also possible to prevent crack damage on the inside of the side wall base portion, and thus it is excellent in durability.

The container for transporting a plate-shaped body according to the present invention, which has the above-described problem, has a flat rectangular container body in which a storage portion having an upper opening is formed, and one or a plurality of plate-like members are housed in the storage portion in a flat state. In the container for transporting the plate-shaped body, a concave portion is formed on a peripheral portion of the upper surface of the bottom surface of the storage portion of the container body along the inner surface of the side wall, and the concave portion is for preventing the plate shape stored on the bottom portion. When the peripheral edge of the body abuts, the outer edge side of the bottom surface of the concave portion that is continuous with the inner surface of the side wall has an R curved surface that can avoid stress concentration when the side wall is deformed. The depth of the concave portion is 1/5 or more of the depth of the accommodating portion of the container body and 1/2 or less of the thickness of the bottom portion, and the radius of the R curved surface at the boundary portion between the bottom surface of the concave portion and the inner surface of the side wall is The accommodating portion has a depth of 1/5 or more and is formed not to exceed the depth of the concave portion. The inner surface of the side wall of at least one side surface of the accommodating portion of the container body has a tapered shape which is inclined outward from the lower end toward the upper end.

According to the container for transport of the present invention, the peripheral portion of the plate-like body such as the glass substrate accommodated in the container body is held at a position of the recessed portion of the peripheral portion of the container body over the entire circumference, and is kept at a position Since the upper surface of the bottom is in contact and floats, even if the peripheral portion of the container body is slightly bent and deformed by operational vibration or drop impact such as handling or conveying work, the peripheral edge of the plate-like body does not contact the upper surface of the bottom.

Further, when an internal load caused by, for example, a plate-like body as a storage object acts on the side wall due to a drop impact or the like in the operation of the conveyance or conveyance operation, and the side wall is to be deformed toward the outside, the bottom surface and the side wall of the concave portion Since the boundary portion continuous on the inner surface is continuous by the R curved surface, the force acting on the boundary portion is dispersed, and deformation of the side wall toward the outer side can be allowed to be prevented, and cracking of the boundary portion can be prevented.

The container for transporting the plate-like body may have a depth of the concave portion larger than that of the previous portion, and a radius of the R curved surface of the continuous portion may be set to be large. It is especially preferred that the radius of the R curved surface is equal to the depth of the recess. Further, the side wall becomes more easily deformed outward, the effect of stress dispersion becomes large, and the horizontal displacement of the accommodated plate-like body can be allowed to some extent.

The container for transfer may have a configuration in which a plurality of plate-like members are placed in a flat state and are stacked and housed, and an upper end portion of the side wall of the outer peripheral portion of the container body is provided. And a fitted and covered cover. Further, the container body may have one accommodating portion that accommodates one or a plurality of plate-like members in a flat state, and the container body in a state in which the plate-like body is housed in the accommodating portion may be stacked without a lid.

In either case, it is preferable that the concave portion of the peripheral portion of the bottom upper surface of the accommodating portion is continuously formed over the entire circumference along the inner surface of the side wall from the viewpoint of protecting the peripheral edge of the plate-shaped body to be accommodated.

In particular, in a case where the inner surface of the side wall of the four corner portions of the accommodating portion of the container body is provided with a slit portion which is formed to be expanded from the inner side surface of the side wall, the bottom portion of the cutout portion is formed continuously from the concave portion The expanded concave portion formed by the expansion, and the outer edge side of the bottom surface of the expanded concave portion is continuous with the inner surface of the side wall by the R curved surface continuous from the concave portion, so that the corner portion of the plate-shaped body can be prevented from abutting against the side wall by the notched portion The inner surface also prevents the occurrence of cracks at the boundary portion between the bottom surface of the expanded concave portion formed by the slit portion and the inner surface of the side wall.

Further, the present invention can be configured such that the container body is arranged in at least one direction of the longitudinal and lateral directions and is formed with a plurality of storage portions at intervals, and the state in which the plate-shaped body is accommodated in each of the storage portions The container bodies can be stacked without a lid.

Further, a fitting mechanism composed of concave and convex shapes corresponding to each other may be provided at an upper end portion of the side wall of the outer peripheral portion of the container body and a peripheral portion of the bottom lower surface of the container body, and may be provided when the plurality of container bodies are stacked Phased.

In these cases, the plate-like body accommodated in each of the accommodating portions is held in a state where it is not floated in contact with the upper surface of the bottom portion at the position of the concave portion, and thus the periphery of the container body is caused by vibration or a drop impact or the like. The part is slightly bent and deformed, the peripheral edge of the plate-shaped body does not contact the upper surface of the bottom, and when the side wall is to be deformed outward, since the boundary portion between the bottom surface of the concave portion and the inner surface of the side wall is continuous by the R curved surface, The force acting on the boundary portion is dispersed, and cracking at the boundary portion can be prevented.

In the container for transporting the plate-shaped body, it is preferable that the depth of the concave portion is 1/5 or more of the depth of the accommodating portion of the container body and 1/2 or less of the thickness of the bottom portion, and the bottom surface and the side wall of the concave portion The radius of the R curved surface at the boundary portion of the surface is 1/5 or more of the depth of the accommodating portion, and is formed not to exceed the depth of the concave portion.

In the transport container of the above-described type, the flexible printed wiring board accommodating portion is continuously formed in one side of each accommodating portion, and the flexible printed wiring board accommodating portion is accommodated in the plate-like body. A flexible printed wiring board unit is provided. Thereby, the plate-shaped body which has a flexible printed wiring board part can be accommodated stably.

(Effect of the new creation) As described above, the container for transporting the plate-shaped body according to the present invention can prevent the peripheral edge of the plate-like body from abutting on the bottom while the plate-shaped body such as a glass substrate is housed. In the case of the surface, and even if a force to be deformed outward is applied to the side wall of the container body due to vibration or drop impact in the operation of conveyance, handling, or the like, the bottom surface of the concave portion and the inner surface of the side wall can be prevented. Cracks are formed at the boundary portion to improve durability, and further, it is not necessary to make the wall thickness of the container body excessive.

The above described features and advantages of the present invention will become more apparent and understood from the following description.

Next, an embodiment of the novel creation will be described based on the examples shown in the drawings.

1 to 6 show an example (first example) of the container for transporting a plate-shaped body according to the present invention. The container A1 of the present embodiment includes a container body 1 having a flat rectangular shape or a square rectangular shape, and is open at the upper side, and the plate-shaped body B such as a glass substrate to be stored can be partitioned between the respective plate-shaped bodies. The protective sheet (not shown) is placed in a state of being overlapped, and the lid body 3 is fitted and covered with respect to the container body 1.

As a covering structure of the lid body 3 to the container body 1, at the open end portion of the upper end of the side wall of the container body 1, the convex edge 11 is left on the inner side and the slit portion 12 is formed on the outer side, and on the other hand, the cover is formed on the outer side. On the lower surface side of the peripheral edge portion 31 of the body 3, a fitting wall portion 32 that faces downward is fitted, and the fitting wall portion 32 is fitted into and abuts against a slit portion of the outer side of the convex edge 11 of the opening end portion. 12, the lid body 3 can be held in a state in which the container body 1 is covered by the fitting of the fitting wall portion 32.

The container body 1 is formed of a cushioning synthetic resin foam, and the accommodating portion 10 is formed by the respective side walls 14a, 14b, 14c, and 14d which are erected from the bottom portion 13. The accommodating portion 10 has a depth (the accommodating portion depth D1) at which the plurality of plate-like bodies B that are stacked with each other across the protective sheet can be accommodated. In general, the number of sheets that can be accommodated differs depending on the thickness of the plate-like body B. For example, in the case of a plate-shaped body B such as a glass substrate having a thickness of 2 mm to 5 mm, it is possible to accommodate ten or more sheets, preferably ten sheets. It is relatively shallow to a few dozen or so.

On the upper surface of the bottom portion 13 of the container body 1, that is, the peripheral portion of each of the side walls 14a, 14b, 14c, 14d of the bottom upper surface 13a of the accommodating portion 10, a recess 15 is formed, which is used for the recess 15 The contact of the peripheral edge of the plate-shaped body B accommodated in the bottom part 13 is avoided. Preferably, the concave portion 15 is continuously formed over the entire circumference along the inner surfaces of the side walls 14a, 14b, 14c, and 14d. However, the concave portion 15 may be formed in the form of a peripheral portion of the plate-shaped body B, for example, an attachment state or storage of an attachment. The arrangement of the portions 10 is formed intermittently in the circumferential direction or by removing the required side portions.

The depth D2 of the concave portion 15 is generally sunk to the upper surface 13a of the bottom portion 13 to be 1/5 or more of the depth D1 of the accommodating portion and 1/2 or less of the thickness of the bottom portion 13, preferably at least 5 mm or more. More preferably, the depth is about 10 mm to 20 mm. Further, the outer edge side of the bottom surface 15a of the concave portion 15 is continuous with the inner surface of the side wall by the R curved surface, and the R curved surface can avoid stress concentration when the side walls 14a, 14b, 14c, and 14d are elastically deformed outward. That is, the outer edge side of the inner surface of the side wall is continuous in an R curved surface. 16 denotes a boundary portion of the R curved surface.

Further, in the four corner portions of the accommodating portion 10 which are formed by the side walls 14a, 14b, 14c, and 14d of the container body 1, a vertical slit portion 17 which is formed to expand from the inner surface side of the side wall is formed, and the slit portion 17 is formed. The bottom portion is formed as an expanded concave portion 18 that is continuously expanded from the concave portion 15 at the same depth as the concave portion 15, and the outer edge side of the bottom surface 18a of the expanded concave portion 18 is also the same as the bottom surface 15a of the concave portion 15 The R curved surface is continuous with the inner surface of the side wall, and the R curved surface can avoid stress concentration when the side walls 14a, 14b, 14c, and 14d are elastically deformed toward the outside. 19 denotes a boundary portion of the R curved surface.

The R curved surface of the boundary portion 16 of the bottom surface 15a of the concave portion 15 and the inner surfaces of the side walls 14a, 14b, 14c, and 14d, and the radius R of the R curved surface of the boundary portion 19a of the expanded concave portion 18 and the boundary portion 19 of the side wall inner surface When the depth D2 of the recessed portion 15 is 1/5 or more of the depth D1 of the accommodating portion and 1/2 or less of the thickness of the bottom portion 13, it is normally set to 1/5 of the depth D1 of the accommodating portion similarly to the depth D2 of the recess portion. Above and not greater than the depth D2 of the recess 15, that is, the center of curvature O set to the radius R is not located above the upper surface 13a of the bottom portion 13. Thereby, the depth of the concave portion 15 can be set larger than the previous one, and the radius R of the R curved surface of the continuous portion 16 can be set in the transport container for the heavy-duty reuse of the required plurality of plate-shaped bodies B. Set it larger. In addition, the interval between the inner surfaces of the side walls on the upper surface 13a of the accommodating portion 10 which is the mounting surface of the plate-like body B is not narrowed, and the same required accommodating space can be secured. It is particularly preferable that the radius R of the R curved surface is equal to the recess depth D2 (same size). Thereby, the concave bottom surface 15a or the bottom surface 18a of the expanded concave portion 18 is continuous with the inner surface of the side wall with one R curved surface, so that the effect of stress dispersion becomes large.

In addition, the inner faces of the side walls of at least one side of the accommodating portion 10 of the surrounding side walls 14a, 14b, 14c, 14d, for example, the inner faces of the opposite side walls 14a, 14c or the side walls 14b, 14d can be as shown in FIG. In the same manner as the broken line, it is an inclined surface such as a tapered shape that is inclined outward from the lower end toward the upper end. At this time, the side walls become more easily deformed outward, and the effect of stress dispersion becomes large.

At least one pair of opposing side walls of the four side walls 14a, 14b, 14c, 14d of the container body 1, for example, on the inner faces of the side walls 14a, 14b, 14c, 14d, as shown, on the sides At least a portion of the central portion of the longitudinal direction and the like is provided with at least one slit recess 20 for accommodating and removing the plate-shaped body B, and the slit recess 20 has a groove shape in the vertical direction. The slit recess 20 has a groove shape extending from the upper end of the side wall to the bottom surface 15a of the recess 15 of the bottom portion 13, so that the portion of the slit recess 20 can be inserted and sealed during the storage and removal operation of the plate-shaped body B. The tip is fastened under the lowermost plate-shaped body B, or the mechanical locking mechanism can be inserted into the portion on the bottom portion 13 and locked under the lowermost plate-shaped body B.

At the portion of the cutout recess 20, the boundary portion from the recess bottom surface 15a toward the inner surface of the cutout recess 20 is also formed to be continuous with the same R curved surface.

The lid body 3 is formed of the same cushioning synthetic resin foam as the container body 1, and as described above, the opening end of the container body 1 can be passed through the fitting wall portion 32. The fitting flange 11 is fitted and covered.

In the case of the figure, on the lower surface of the lid body 3, the peripheral portion of the peripheral portion 31 along the inner surface of the fitting wall portion 32, and the bottom upper surface 13a of the container body 1 Similarly to the recessed portion 15, the recessed portion 33 is continuously formed in the circumferential direction, and the recessed portion 33 prevents the peripheral edge of the plate-shaped body B accommodated from coming into contact with each other. In the state in which the container body 1 is covered, the upper ends of the side walls 14a, 14b, 14c, and 14d of the container body 1 abut against the bottom surface of the recess 33. The upper surface 3a of the peripheral edge portion 31 of the lid body 3 is provided with a fitting flange 34 for stacking, and is formed so as to be attached to the lower surface 13b of the bottom portion 13 of the container body 1 when the transport container A1 is stacked. The peripheral portion 13c and the inner portion of the lower surface 13b are fitted inside.

Reference numerals 29 and 39 in the drawing denote recesses for a bead which are formed in a groove shape on the lower surface of the bottom of the container body 1 and the flange 34 of the peripheral edge portion 31 of the lid body 3, respectively. Symbol 40 is a buckle.

As a constituent material of the container body 1 and the lid body 3, polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer can be used. Polystyrene resin such as styrene-acrylonitrile copolymer, polyolefin resin such as polyethylene, polypropylene or ethylene-vinyl acetate copolymer, polylactic acid or polyterephthalic acid A foam of various synthetic resins such as a polyester resin such as polyethylene terephthalate. Among them, a molded body formed of a bead foam composed of a composite resin containing a polystyrene resin and a polyolefin resin is particularly preferable. The pellet foam containing the composite resin of the polystyrene resin and the polyolefin resin can be made of the foamable resin particles impregnated with the foaming agent after the styrene monomer is polymerized to the polyolefin resin particles. Steam heating is performed to obtain a molded body.

According to the container A1 for transporting the plate-shaped body of the first example, various glass substrates such as the original plate glass and the liquid crystal display, a panel such as a touch panel, and the other plate-shaped body B can be housed. At this time, on the bottom portion 13 in the container main body 1, a protective sheet for partitioning having a thickness of 0.2 mm to 5.0 mm and the sheet-like body B are alternately stacked and housed. After the plate-shaped body B is housed in this manner, the container body 1 is covered with the body 3. Then, the entire transport container A1 is buckled (not shown) for transport or the like.

In the above-described use, the plate-like body B accommodated in the transport container A1, in particular, the peripheral edge of the lowermost plate-shaped body B is located at the position of the concave portion 15 of the peripheral portion of the upper surface 13a of the bottom portion 13 Keep it in a floating state. Therefore, the peripheral edge of the plate-like body B is maintained so as not to contact the upper surface of the bottom portion due to vibration during transportation. If the concave portion 15 is continuous over the entire circumference in the circumferential direction, the peripheral edge of the plate-like body B is kept over the entire circumference so as not to contact the upper surface of the bottom portion. Further, at the four corner portions of the container body 1 formed by the side walls 14a, 14b, 14c, and 14d, there are provided cutout portions 17 which are formed to expand toward the inner sides of the side walls 14a, 14b, 14c, and 14d, and the bottom portion of the cutout portion 17 is formed to be Since the concave portion 15 continuously expands the concave portion 18, the corner portion of the plate-shaped body B accommodated therein is kept from abutting against the inner surface of the side wall, and the corner portion can be prevented from being damaged.

Further, in the case of the transport container A1 of the above-described example, the outer edge side of the bottom surface 15a of the concave portion 15 and the outer edge side of the bottom surface 18a of the expanded concave portion 18 are continuous with the inner surface of the side wall by the R curved surface. This R curved surface can avoid stress concentration when the side walls 14a, 14b, 14c, and 14d are elastically deformed toward the outside. Therefore, in the operation of transportation or the like, if an impact due to a side drop or the like is exerted, and a force for folding the side walls 14a, 14b, 14c, 14d outward is generated, the bottom surface of the concave portion 15 can be passed. The R-curved surface of the boundary portions 16 and 19 between the bottom surface 18a of the expansion recess 18 and the inner surface of the side wall to disperse the force acting on the boundary portions 16, 19 allows the side walls 14a, 14b, 14c, 14d to face The warping deformation of the outer side is suppressed to a certain extent, and the occurrence of cracks in the boundary portions 16 and 19 can be suppressed. Further, even in a container of a synthetic resin foaming system, separation of the side walls due to cracks can be prevented, and the crack can be improved. Durability. Therefore, it is not necessary to make the wall thickness of the container body 1 excessively large or to increase the strength, and it is possible to contribute to high foaming ratio and thinning of the foamed resin material, and it can be manufactured and provided at a low cost.

7 to 9 show another example (second example) of the container for transporting the plate-shaped body of the present invention. In the configuration of the container body 1 of the present embodiment, the same components as those of the above-described examples are denoted by the same reference numerals and will be briefly described as necessary, and a configuration different from the above-described examples will be mainly described.

In the case of the transport container A2 of the present embodiment, the container body 1 having a rectangular shape is formed of the same synthetic resin foam as described above, and has the side walls 14a, 14b, 14c, and 14d as the frame portions for stacking. In the accommodating portion 10 of the accommodating portion 10, one sheet-shaped body B such as a glass substrate or a panel to be transported, or a protective sheet is accommodated in the bottom portion 13 of the accommodating portion 10 The plurality of plate-like bodies B which are overlapped by the material (also serving as a protective spacer) are stacked and packaged, for example.

In the peripheral portion of the upper surface 13a of the bottom portion 13 of the accommodating portion 10 along the inner surfaces of the side walls 14a, 14b, 14c, and 14d, as in the above-described example, the concave portion 15 is continuously formed mainly over the entire circumference. The recess 15 is for avoiding the contact of the peripheral edge of the plate-shaped body B accommodated. In the present example, the recess 15 does not necessarily need to be continuous throughout the entire circumference. Further, in the four corner portions of the container main body 1 formed by the respective side walls 14a, 14b, 14c, and 14d, a slit portion 17 that is formed to expand from the inner surface side of the side wall is formed, and the bottom portion of the slit portion 17 is formed as a slave portion. The concave portion 15 continuously expands the formed expansion concave portion 18 at the same depth as the concave portion 15. Further, the outer surface side of the bottom surface 15a of the concave portion 15 continuous to the inner surface of the side wall and the outer edge side of the bottom surface 18a of the expansion concave portion 18 are respectively R curved surfaces, and the R curved surface can avoid the side walls 14a, 14b, 14c, 14d. Stress concentration at the time of elastic deformation toward the outside. 16 and 19 denote boundary portions formed by the R curved surface between the concave portion 15 and the expanded concave portion 18 and the inner surface of the side wall.

In the case of the present example, the depth D2 of the concave portion 15 is also set to be 1/5 or more of the depth D1 of the accommodating portion, and the radius R of the R curved surface is set to be the depth D1 of the accommodating portion so as not to be larger than the depth D2 of the concave portion 15. In the case of a shallow container in which one sheet of the sheet B is accommodated, it is more preferably 1⁄2 or more. Thereby, the effect of stress dispersion is increased by the R curved surface which is continuous from the bottom surface 18a of the recessed portion or the bottom surface 18a of the expanded concave portion 18 on the boundary portions 16 and 19 of the inner surface of the side wall. In the case of a container stacked without a lid, the height of the side wall, that is, the depth of the accommodating portion may be set to a height several times the thickness of the bottom portion. At this time, the radius of the R curved surface may be 1/5 or less of the depth of the accommodating portion in a range in which stress concentration can be prevented.

Further, although not shown, it is preferable that the same concave portion is formed on the lower surface of the bottom portion 13 at a position corresponding to the concave portion 15, and the plate-like body B is housed. In the stacked state, the surfaces of the respective sides of the plate-like body B housed in the container body 1 of the lower stage do not contact the lower surface of the bottom of the container body 1 of the upper stage.

The conveying container A2 is formed with a notch portion 22 at a portion of a desired width of the peripheral edge of the lower surface 13b of the bottom portion 13 of the container body 1, wherein the notch portion 22 can be fitted to the upper end of the side wall of the container body 1 of the lower stage when stacked. The upper end portion of the side walls 14a, 14b, 14c, and 14d is fitted to the notch portion 22, and the inner portion of the lower surface 13b of the bottom portion 13 of the accommodating portion 10 is fitted to the accommodating portion 10 of the lower container. Further, in the fitted state, the gap (space) of the accommodating portion 10 of the plate-like body B can be secured on the bottom portion 13 of the accommodating portion 10.
