Description

  The present invention transports and stores various glass substrates and panels, such as glass substrates for glass and liquid crystal displays and plasma displays, and in particular, plate-like bodies having a flexible portion that forms a flexible wiring board on one side of the panel. The present invention relates to a container for transporting a plate-like body used for the above.

  Conventionally, as a transport container for storing and transporting relatively large glass substrates such as glass plates for glass, liquid crystal displays, etc., or panels such as solar cell panels and touch panels, and other impact-sensitive plates. A container body made of a synthetic resin foam having a cushioning property and a lid body, and the plate-like body is placed in a longitudinal groove arranged in parallel at equal intervals on the inner surface of one opposite side wall of the container body. In general, those inserted one by one and supported and stored in an upright state so as not to contact each other have been used.

  However, in the conventional method of accommodating a plate-like body such as a glass substrate in an upright state by a vertical groove on the inner surface of the side wall, the plate-like body itself is bent and deformed by its own weight, or the weight of the plate-like body is at the bottom of the container body. When the load is concentrated, the bottom of the container is compressed and deformed, and the cushion function and the impact relaxation function may be impaired.

  In order not to cause such a problem, as illustrated in Patent Documents 1 to 3, a plate body to be transported such as a glass substrate and a protective sheet are alternately stacked and stored in a horizontal state in the container body. And the container for conveyance which came to receive each plate-shaped body by the surface through the sheet | seat for protection has appeared (patent documents 1-3). In the case of a transport container that stores a plate-like body such as a glass substrate in a horizontal state, the peripheral edge and corner of the stored plate-like body are easily affected by vibration and impact during transportation, and the container body There is a risk of damage due to contact with the bottom surface or the inner surface of the side wall. Therefore, for example, contact with the side wall of the corner portion is avoided, and the periphery of the plate-like body is supported by contacting a flexible contact member, or contact with the inner surface of the side wall of the glass substrate is reduced. Various ideas have been made.

  By the way, as illustrated in FIGS. 18 and 19, a flexible part b2 having a flexible printed wiring board is connected to one side of the panel body b1 on a plate-like body such as a touch panel to be transported or a liquid crystal display panel. Although it may be provided, the device as a conveyance container for conveying plate-like bodies B, such as a panel provided with such a flexible part b2, is not fully made.

  That is, the flexible part b2 connected to one side part of the panel main body part b1 is a flexible connecting part formed by providing a wiring board part b3 configured by providing a metal conductive plate and a protective layer on the surface of the core material of the flexible printed wiring board. It is connected to the panel body b1 at b4, and is more easily damaged by vibration and impact than the panel body b1, and is also easily deformed by bending. Moreover, the wiring board part b3 of the flexible part b2 is usually provided with electronic components so that the thickness t2 of the flexible part b2 is larger than the thickness t1 of the panel body part b1. Therefore, as a container for transporting the plate-like body B with the flexible portion, in order to protect the flexible portion b2, it is necessary to devise a storage state so that the flexible portion b2 is not loaded as much as possible. In the case of this transport container, the fact is that sufficient consideration has not been given to the protection of the flexible part.

  For example, in the case of a plate-shaped conveyance container with a flexible portion, a flexible storage portion for storing the flexible portion is formed on one side of the main storage portion that stores the panel main body portion. In the storage portion, a recess is required to escape the thickness of the flexible portion that is larger than the thickness of the panel body portion. As shown in FIG. 20, when the concave portion 136 is formed on the inner surface of the ceiling portion 130 of the lid body 103 in order to release the thickness of the flexible portion b <b> 2 whose thickness is larger than the panel body portion b <b> 1 of the plate-like body B, There is a possibility that the portion 130 becomes thin and breaks due to contact with the flexible portion b <b> 2 due to deformation of the lid 103. However, if the thickness of the ceiling portion 130 is increased, the overall thickness T2 of the container by the container body 101 and the lid body 103 is increased, which is uneconomical, and a large number of containers for transportation are stacked in a stacked state. This also reduces the efficiency.

  In order to solve the above problems, the present invention protects a stored plate-like body as a container for carrying the plate-like body for storing and transporting a plate-like body with a flexible portion in a flat state. In particular, the flexible part can be well protected, and it is not necessary to excessively increase the thickness of the lid, and it is intended to provide a plate-like container for transportation that can keep the overall thickness of the container low, In particular, this type of transport container has a bottom angle drop and bottom ridge drop in a drop test, and a predetermined strength is required, so the thickness of the bottom of the container body is the thickness of the top plate of the lid. The problem is solved by forming the relief portion of the thickness of the flexible portion by utilizing the thickness of the bottom portion of the container body, paying attention to the fact that it is larger.

  The plate-shaped conveyance container of the present invention that solves the above-mentioned problems has a flat rectangular container body formed from a synthetic resin foam and formed with a main storage portion that opens upward, and the main storage portion In addition, a container for transporting and transporting one or a plurality of flexible plate-equipped plate-like bodies in a flat state, wherein the plate-like body is continuous with at least one side of the main storage portion in the container body. A flexible storage portion for storing a flexible portion connected to the body is formed, and an inner bottom surface of the flexible storage portion is recessed so as to form a downwardly inclined surface toward the outside. And

  According to this container for conveyance, while storing a plate-shaped body in the main storage part of a container main body, and storing the flexible part connected with the plate-shaped body in a flexible storage part, the panel main-body part of a plate-shaped body The thicker flexible part is held stably without being higher than the panel main body along the inclined inner bottom surface, and the flexible part contacts the container main body or the lid and is deformed or damaged. The flexible part can be well protected. In particular, even when a plurality of plate-like bodies are stacked in the storage section of the container body and stored in a flat state, and the lid body is attached and packaged, the thickness of the top plate portion of the lid body is reduced. Since it is not necessary to make it large, an increase in the thickness of the entire container can be suppressed.

  In the container for transporting a plate-like body according to each of the inventions, it is preferable that the inner bottom surface of the flexible housing portion continuously forms an inclined surface with a rounded curved surface from the inner bottom surface of the main housing portion of the container body. Thereby, the flexible part accommodated in the flexible accommodation part is hold | maintained without a possibility of bending and bending deformation in the base part by the side of a panel main-body part.

  In the transport container, it is preferable that the inner surface of the side wall that continues from the inner bottom surface of the flexible storage portion forms an inclined surface that is inclined outward from the lower end portion toward the upper end. Thereby, even when horizontal displacement occurs due to horizontal vibration or drop impact of the container, the flexible portion can be prevented from coming into contact with the side wall, and the flexible portion can be further protected.

  In the container for transporting the plate-shaped body, the container main body is stored in a flat state in a state where a plurality of plate-shaped bodies are stacked in one main storage portion, and the upper end of the side wall of the container main body In contrast, a lid made of a synthetic resin foam that can be fitted is provided. In this case, since the flexible storage portion is formed as described above, the thickness of the flexible portion when the plurality of plate-shaped bodies are stacked and stored can be absorbed by the downward inclined surface, and becomes higher than the panel main body portion. Since there is no need to increase the thickness of the ceiling of the lid, the thickness of the entire container can be suppressed.

  In the plate-shaped container, the container body has a plurality of main storage portions formed at intervals, and stores a flexible portion continuously to one side of each main storage portion. A flexible storage portion may be formed, and the inner bottom surface of each flexible storage portion may be recessed so as to form an inclined surface that is inclined downward toward the outer side as viewed from the main storage portion. In this case as well, the panel body is stored in each main storage part of the container body, and the flexible part is stored in each flexible storage part so that the flexible part is held along the inclined inner bottom surface. It does not become higher than the main body, so that the main storage portion does not need to be excessively deep.

  Also in the above-described transport container, similarly to the above, it is preferable that the inner bottom surface of each flexible storage portion continuously forms an inclined surface with a rounded curved surface from the inner bottom surface of each main storage portion, and is stored in the flexible storage portion. It is possible to prevent bending and bending deformation of the flexible portion.

  In the container for transporting the plate-like body, a notch step portion is formed on the outer peripheral side of the upper end portion of the side wall in the outer peripheral portion of the container main body, leaving a convex portion on the inner side, and on the peripheral portion of the bottom lower surface of the container main body. And a protruding edge that can be fitted to the notch step portion of the upper end portion of the side wall of the container body having the same shape. It can be provided so that it can be stacked. Thereby, the several container main body which accommodated the plate-shaped object can be stacked and conveyed without a lid.

  According to the container for transporting a plate-like body of the present invention, the panel body portion of the plate-like body with a flexible portion such as a glass substrate provided with the flexible portion is stored in the main storage portion in the container body, and the panel body By storing and supporting a flexible part thicker than the bottom part in a flexible storage part that is recessed so as to form a downwardly inclined surface using the thickness of the bottom part, It can be held stably without any load and without fear of deformation or breakage, and can be well protected.

  Moreover, since the flexible part stored in the flexible storage part can be held without being higher than the panel main body part, when storing a single plate-like body, of course, when storing a plurality of plate-like bodies in a stacked state However, the increase in the thickness of the entire container can be suppressed, so that the container can be efficiently conveyed without lowering the loading efficiency on the transportation vehicle or the like.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIGS. 1-9 has shown one Example of the container for conveyance of the plate-shaped object concerning this invention. The transport container A1 of this embodiment opens upward, and a plate-like body B such as a glass substrate or a panel to be stored, particularly a plate-like body B with a flexible portion illustrated in FIG. The container body 1 has a flat rectangular shape or a square flat rectangular shape that can be stored in a stacked state via a spacer protective sheet (not shown), and a lid 3 that can be attached to the container main body 1.

  As an attachment structure of the lid body 3 to the container body 1, a cutout step portion 12 is formed on the outer side at the upper end portion of the side wall forming the outer periphery of the container body 1, leaving the convex edge 11 on the inside, On the lower surface side of the peripheral edge portion 31 of the lid body 3, a downward-facing fitting wall portion 32 that fits and contacts the notch step portion 12 outside the convex edge 11 at the opening end portion is suspended. The lid 3 can be held in a state of being attached to the container body 1 by the fitting by the fitting wall portion 32.

  The container body 1 is mainly formed of a synthetic resin foam having a buffer property, and is opened upward by the four side walls 14a, 14b, 14c, and 14d that rise from the bottom portion 13, and is a panel of the plate-like body B. One main storage portion 10 capable of storing the main body portion b1 is formed. The main storage portion 10 is formed to a depth capable of storing the required number of panel bodies B1 of the plate-like bodies B that are stacked via a protective sheet. Usually, depending on the thickness of the plate-like body B, for example, in the case of the plate-like body B such as a glass substrate having a thickness of 2 to 5 mm, it is relatively shallow so that 10 sheets or more, preferably about 10 to several tens of sheets can be accommodated. It is formed.

  A flexible storage portion 15 for storing a flexible portion b2 connected to the panel body portion b1 of the plate-like body B is continuously provided on one side portion of the main storage portion 10, for example, one side portion on the side wall 14c side. Is formed. The flexible storage portion 15 has an inner bottom surface (bottom surface top surface) 15a continuously outward from the inner bottom surface (top surface of the bottom portion 13) 10a of the main storage portion 10 by utilizing the thickness of the bottom portion 13. Is recessed so as to form a downwardly inclined surface, so that an increase in the thickness of the accommodated flexible portion b2 can be avoided. Since the range of the recessed portion by the inclined surface of the inner bottom surface 15a of the front flexible container 15 is a part and the degree of the recessed portion is slight, the strength of the container body 1 is hardly affected.

  Usually, the plate-like body B is provided with a flexible portion b2 that is shorter than the length of the side portion of the panel body portion b1 and is connected to the center portion while leaving both side end portions of the side portion. For this reason, the flexible storage portion 15 corresponds to the form of the flexible portion b2 so that both side end portions of one side portion of the storage portion 10 remain at the same height as the side wall, so that the flexible storage portion 15 is more flexible than the flexible portion b1. The remaining portion is formed so as to serve as a receiving portion 16 with which both end portions of the panel main body b2 of the plate-like body B are in contact with each other, and is stored in the flexible storage portion 15. The formed flexible part b2 is formed so as not to contact the side wall 14c.

  The inclination of the inner bottom surface 15a of the flexible storage portion 15 is determined when the maximum number of sheets is stored in consideration of the stacking height H1 when the flexible portions b2 corresponding to the maximum number of stored sheets of the plate-like body B are stacked. It is particularly preferable that the flexible portion b2 is set so as not to be higher than the panel body portion b1 of the plate-like body B stored in an overlapping manner.

  The inner surface of the side wall 14c continuous from the inner bottom surface 15a of the flexible storage portion 15 forms a vertical surface (including the case of having a draft on molding) with respect to the bottom portion 13 as shown in FIGS. However, as shown in FIG. 10 and FIG. 11, it is preferable to form an inclined surface that is inclined outward from the lower end portion toward the upper end. Even when the plate-like body B stored in a state where the sheets are stacked is largely displaced toward the flexible storage portion 15 toward the upper layer side, the flexible portion b2 is difficult to contact the inner surface of the side wall 14c of the container body 1, and the flexible portion b2 Can be well protected.

  Further, the inner bottom surface 15a of the flexible storage portion 15 is bent in the vicinity of the boundary with the inner bottom surface 10a of the main storage portion 10 to form a continuous inclined surface, as shown in FIG. It can be formed so as to form an inclined surface having a predetermined inclination angle via a rounded curved surface portion 17 which gradually inclines downward from a continuous horizontal state from the inner bottom surface 10a of the portion 10. The rounded curved surface portion 17 is a portion corresponding to the base portion of the flexible portion b2 of the stored plate-like body B, that is, a position below the boundary portion between the inner bottom surface 10a of the main storage portion 10 and the inner bottom surface 15a of the flexible storage portion 15. In addition to an arcuate curved surface as a fulcrum, it can be set in consideration of the natural bending condition of the flexible portion b2, such as forming a curved surface through a horizontal portion continuous with the bottom surface 10a.

  By forming the rounded curved surface portion 17 in this way, the flexible portion b2 of the stored plate-like body B comes into contact with the inclined inner bottom surface 15a of the flexible storage portion 15 in a natural bent state, and The bending of the flexible portion b2 of the lower plate-like body B among the plate-like bodies to be stored can be prevented. Further, since the inner bottom surface 15a of the flexible storage portion 15 is not an inclined surface formed by being refracted at the boundary with the inner bottom surface 10a of the main storage portion 10, the flexible storage portion 15 is bent from the base portion on the panel main body side. It is not shaped into a deformed state.

  Also in this embodiment, the inner surface of the side wall 14c of the flexible container 15 may be formed as a vertical surface with respect to the bottom 13, or an inclined surface inclined outward toward the upper end as shown in the figure. However, when the plate-like body B is displaced due to horizontal vibration or dropping of the container, the flexible portion can be formed by forming it on an inclined surface. b2 becomes difficult to contact the inner surface of the side wall 14c, and the flexible portion b2 can be well protected.

  In any of the above-described embodiments, although not shown in the drawings, the continuous portion when the bending deformation occurs is that the inner bottom surface 15a of the flexible housing portion 15 is continuously curved with the inner surface of the side wall 14c. This is preferable because it can suppress the generation of cracks.

  In the case of the embodiment of FIGS. 1 to 9, the peripheral portion along the four side walls 14 a, 14 b, 14 c, 14 d of the inner bottom surface 10 a of the main storage portion 10 of the container body 1 is stored on the bottom portion 13. A recess 18 for avoiding contact of the peripheral edge of the panel main body b <b> 1 of the plate-like body B is continuously formed except for a continuous portion with the flexible container 15. And the outer edge side of the bottom face 18a of the said recessed part 18 is following the side wall inner surface with the rounded curved surface which can avoid the stress concentration at the time of the elastic deformation to the outward of the side walls 14a, 14b, 14c, 14d.

  Further, at the four corners of the main storage portion 10 by the side walls 14a, 14b, 14c, and 14d of the container body 1, there are formed vertical cutout portions 19 extended from the side wall inner surface side. The bottom is continuously extended from the recess 18 at the same depth as the recess 18. The bottom of the notch 19 is also a curved surface and is continuous with the inner surface of the side wall.

  Furthermore, each side wall except for the opposite side walls of at least one of the four side walls 14a, 14b, 14c, 14d of the container body 1, for example, the side wall 14c on the side where the flexible container 15 is formed as shown in the figure. The inner surfaces of 14a, 14b, and 14d have at least one notch recess 20 for storing and taking out the plate-like body B having a concave groove shape in the vertical direction at a required portion such as a central portion in the length direction of the side. One is provided. The notch recess 20 has a recessed groove shape having a depth extending from the upper end of the side wall to the bottom surface 18a of the recess 18 of the bottom portion 13, and the notch recess 20 is formed at the portion of the notch recess 20 when the plate body B is stored and taken out. So that the fingertip can be hung under the lowermost plate B or inserted into the upper part of the bottom 13 by inserting a mechanical locking means under the lowermost plate B. It can be locked.

  Also at the location of the notch recess 20, it is desirable that the boundary from the recess bottom surface 18a to the inner surface of the notch recess 20 is formed to be continuous with the same rounded curved surface as described above.

  The lid 3 is formed of a synthetic resin foam having a buffer property similar to that of the container body 1 and, as described above, a fitting wall with respect to the fitting ridge 11 for fitting at the opening end of the container body 1. It is provided so that it can be attached by fitting the portion 32.

  In the case of the figure, the plate-shaped body accommodated in the peripheral portion along the inner surface of the fitting wall portion 32 on the lower surface of the peripheral portion 31 of the lid 3, similar to the concave portion 18 of the inner bottom surface 10 a of the container body 1. A recess 33 is formed continuously in the circumferential direction so as to avoid contact with the peripheral edge of the B panel body b1. On the side corresponding to the flexible container 15, the width is formed so as to avoid contact of the flexible part b2. In a state where the lid 3 is fitted to the container main body 1, the upper ends of the side walls 14 a, 14 b, 14 c and 14 d of the container main body 1 are in contact with the inner bottom surface of the concave portion 33 (the lower surface of the ceiling portion). It has become. The upper surface 3a of the peripheral portion 31 of the lid 3 is provided with a convex edge 34 for fitting at the time of stacking, and the lower peripheral portion of the bottom portion 13 of the bottom portion 13 of the container body 1 is stacked when the containers A for transporting are stacked. The notch 21 is formed to fit.

  As the constituent material of the container body 1 and the lid 3, polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, polystyrene resin such as styrene-acrylonitrile copolymer, polyethylene, Foams of various synthetic resins such as polyolefin resins such as polypropylene and ethylene-vinyl acetate copolymer, and polyester resins such as polylactic acid and polyethylene terephthalate can be used. Especially, the molded object by the bead foam of the composite resin containing a polystyrene-type resin and a polyolefin-type resin is used suitably. A composite resin bead foam containing a polystyrene resin and a polyolefin resin is obtained by polymerizing a polyolefin resin particle with a styrene monomer and then steam-heating the expandable resin particles impregnated with a foaming agent. A molded body can be obtained.

  According to the plate-like container A1 for transporting the plate-like body according to the above-described embodiment, the flexible portion b2 is continuously provided on one side of the plate-like body B, particularly the panel main body portion b1, such as a glass plate for glass and a liquid crystal display. The plate-like body B with the flexible part is accommodated. At this time, the protective sheet for spacer having a thickness of 0.2 to 5.0 mm and the panel main body part b1 of the plate-like body B are alternately stacked and stored in the main storage part 10 on the bottom part 13 in the container main body 1, Further, the flexible portion b2 is stored in the flexible storage portion 15. After storing the plate-like body B in this manner, the lid body 3 is attached to the container body 1.

  In such a use, the plate-like body B stored in the transport container A1 stores the panel main body portion b1 in the main storage portion 10 of the container main body 1, and the flexible portion connected to the panel main body portion b1. By storing b2 in the flexible storage portion 15 and along the inclined inner surface 15a, the flexible portion b2 having a larger wall thickness than the panel main body portion b1 of the plate-like body B is formed in the container main body 1 within the panel main body. Therefore, the thickness of the ceiling portion of the lid body 3 is formed in the same manner as in the past so that the plate-like body B, particularly the flexible portion b2 can be protected. It can be done well.

  That is, as shown in FIGS. 8 and 9, when 10 to several tens of plate-like bodies are stacked and stored, the height of the overlapping portion of the flexible portion b2 that is thicker than the panel main body portion b1 is the panel main body portion. It does not become higher than the overlapping portion of b1, and is stably held at a predetermined position. Therefore, the flexible portion b2 does not come into contact with the lid body 3 or comes into contact with the inner surface of the side wall, and there is no fear of damage to the flexible portion b due to contact or the like, and the protection can be satisfactorily performed. In particular, when the inner surface of the side wall 14c is inclined outward as shown in FIG. 10 and FIG. 11, the inner bottom surface 15a of each flexible storage portion 15 is provided in the main storage portion 10 as shown in FIG. When an inclined surface is continuously formed from the inner bottom surface 10a with a rounded curved surface, contact of the flexible portion b2 with the side wall 14c, bending deformation, and the like can be prevented, and the protection can be further improved.

  In addition, even when a plurality of plate-like bodies B are stacked and stored in the storage portion 10 of the container body 1 in a flat state, and the lid 3 is attached and packaged, the flexible storage is performed as described above. Since the thickness of the flexible portions b2 of the plurality of plate-like bodies B can be absorbed and stored in the portion 15 by the inclined surface of the inner bottom surface 15a downward, it is not necessary to increase the thickness of the ceiling portion of the lid 3. An increase in the overall thickness T1 can be suppressed. For example, as shown in FIG. 20, in the case of a container in which a concave portion 136 for escaping the thickness of the flexible part b <b> 2 is formed on the inner surface of the ceiling part 130 of the lid 103, the container is secured in order to ensure the thickness of the ceiling part 130 of the lid 103. Although the overall thickness T2 is increased, in the case of the container of the present invention, since the flexible storage portion 15 is formed by utilizing the thickness of the bottom portion 13 of the container body 1 that is originally thick, the thickness of the bottom portion 13 is reduced. There is no need to increase the thickness, and the thickness T1 of the entire container decreases. Therefore, by using the container of the present invention, the container can be efficiently transported without lowering the loading efficiency of the container on a transportation vehicle or the like.

  12-17 has shown the other Example of the container for conveyance of the plate-shaped body which concerns on this invention. In this embodiment, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The transport container A2 of this embodiment is a container composed of a flat rectangular container body 1 formed from the same synthetic resin foam as described above, and the container body 1 is a plate-like body with a flexible portion to be stored. A plurality of main storage portions 10 capable of storing the panel main body portion b1 of B are formed at intervals, and a flexible storage portion that stores the flexible portion b2 continuously to one side of each main storage portion 10 15 is formed, and the inner bottom surface 15a of each of the flexible storage portions 15 is recessed so as to form an inclined surface that is inclined downward toward the outer side as viewed from each main storage portion 10.

  In the case of the figure, the four main storage portions 10 of the container main body are formed in parallel in the front and rear, left and right, respectively, and the flexible storage portions 15 of the two main storage portions 10 that are parallel in the front and rear direction are They are formed to face each other in the center in the direction, and are formed continuously at the lowest position of the inner bottom surface 15a forming an inclined surface. A partition wall 24 having the same height as the outer side walls 14a to 14d is provided between the two main storage units 10 and 10 and the flexible storage units 15 and 15 arranged in parallel in the left and right. The portions between the main storage portions 10 and 10 that are juxtaposed in the front-rear direction are formed continuously with the flexible storage portions 15 and 15 except for the portions that become the receiving portions 26 at both ends of the flexible portion b2 of the plate-like body B. However, a partition wall can also be formed between the flexible storage portions 15 and 15.

  The main storage portion 10 and the flexible storage portion 15 of the container main body 1 of this embodiment are formed to be relatively shallow with a depth that can normally store the panel main body portion b1 and the flexible portion b2 of one plate-like body B. It is also possible to form and implement several plate bodies B so as to be accommodated.

  The number of the main storage units 10 and the flexible storage units 15 and the arrangement direction thereof are not limited to those shown in the drawing, and the main storage units 10 and the flexible storage units 15 may be arranged in the same direction. It is also possible to implement by arranging and forming so that only two plate-like bodies can be stored in parallel.

  In either case, the inner bottom surface 15a of the flexible storage portion 15 continuous to each main storage portion 10 is formed so as to form an inclined surface that is inclined outward from the main storage portion 10. Preferably, as in the case of the above-described embodiment, the inner bottom surface 15a of each flexible storage portion 15 is continuously inclined with a rounded curved surface from the inner bottom surface 10a of each main storage portion 10. . As a result, bending or bending deformation of the flexible portion b2 stored in the flexible storage portion 15 can be prevented.

  In the case of the transfer container A2, the upper end of the side wall of the container main body 1 is formed with a notch step 12 on the outer side, leaving the convex edge 11 on the inner side, and on the outer peripheral portion on the lower surface side of the container main body 1. Is provided with a convex portion 25 that fits into the notch step portion 12 at the upper end of the side wall of the lower container during stacking, and the step portion 25 is fitted in the notch step portion 12. It can be stacked, and in this fitted state, it is formed on the bottom 13 of the main storage recess 10 so as to ensure a space in which the plate-like body B can be stored. Usually, the space does not apply a stacking load to a single plate-like body B, in particular, a plate-like body B in a state where a protective sheet (not shown) such as a film or paper is overlapped and protected on the front and back surfaces. Thus, it is formed so that it can be stored and held and the excessive lifting of the plate-like body B can be restricted.

  Also in the case of this embodiment, the peripheral portion of the bottom portion 13 of each main storage portion 10 has a recess 18 for avoiding contact of the peripheral edge of the panel body portion b1 of the plate-like body B stored on the bottom portion 13. The upper and lower cutouts (not shown) are formed as necessary at the four corners of each main storage 10. Further, the left and right side walls 14b, 14d and the partition wall 24 are formed with notch recesses 20 that can be used for storing and taking out the plate-like body B having a groove shape in the vertical direction.

  In the case of the transport container A2, for example, the panel body b1 of the plurality of plate-like bodies B with flexible portions that are protected by attaching protective sheets such as films and papers to the front and back surfaces, respectively, While being accommodated in the main accommodating part 10, each flexible part b2 continuously provided in this panel main-body part b1 is accommodated in each flexible accommodating part 15 formed continuously by each said main accommodating part 10. FIG. As shown in FIG. 17, the container body 1 containing the plate-like body B in this way has the convex portion 25 formed on the outer peripheral portion on the lower surface side of the upper container body 1 as the upper end of the side wall of the lower container body 1. They are stacked in a state of being fitted to the notch step portion 12 included in the. If necessary, an empty container body 1 that does not store a plate-like body is stacked on the top as a lid. The entire container thus stacked is belted (not shown) and transported or the like.

  Also in this embodiment, by storing the flexible portion b2 connected to the panel main body portion b1 so as to be along the inner bottom surface 15a of the flexible storage portion 15, the flexible portion b2 having a larger wall thickness than the panel main body portion b1 is obtained. Thus, the flexible body b2 can be well protected without excessively increasing the thickness of the bottom 13 of the container body 1 without making it higher than the panel body b1. Moreover, since the increase in the thickness of the whole container can be suppressed, it can be efficiently transported without reducing the loading efficiency on a transportation vehicle or the like.
