  As shown to (a) of FIG. 2, the main body 1A is a rectangular container provided with the opening part 2, and is an integrally molded product. Of the four inner side surfaces 3 (first inner side surfaces) that form the opening 2, a plurality of guide grooves 4 are provided on a pair of inner side surfaces 3 that face each other. A plurality of support grooves 4a are provided on the inner bottom surface 5 of the main body 1A so as to correspond to the guide grooves 4 respectively.

  Here, a direction perpendicular to the outer bottom surface 12 is defined as an X direction. The outer bottom surface is a horizontal surface. In other words, it can be said that the X direction is a direction inverted by 180 ° with respect to the direction of gravity. A direction perpendicular to the X direction and perpendicular to the front or back surface of the plate-like member 8 to be accommodated is defined as a Y direction, and a direction perpendicular to both the X direction and the Y direction is defined as a Z direction. Referring to FIG. 2A, it can be said that the Y direction is the BB line direction and the Z direction is the AA line direction. Referring to FIG. 2B, the Y direction is perpendicular to the X direction and toward the front in the drawing, and the Z direction is perpendicular to the X direction and in the drawing. The direction is from left to right. Further, it can be said that the X direction is the direction of the normal L of the outer bottom surface 12. In addition, the inner bottom surface 5 side and the outer bottom surface 12 side in the main body 1A are the lower side, and the opening 2 side is the upper side.

  The guide groove 4 is a groove for guiding the plate-like member 8 accommodated in the main body 1 </ b> A to the inner bottom surface 5, and extends in the X direction from the opening 2 toward the inner bottom surface 5. Further, the support groove 4a is a groove for supporting an end portion of the plate-like member 8 accommodated in the main body 1A that faces the inner bottom surface 5 and extends in the Z direction.

  The plate-like member 8 is inserted along the guide groove 4 from the opening 2 toward the inner bottom surface 5. The plate-like member 8 is supported and accommodated by the inner side surface 3, the guide groove 4, and the support groove 4a. Here, in the main body 1A, the plurality of plate-like members 8 are accommodated so as to overlap in the Y direction. In other words, the plurality of plate-like members 8 are accommodated such that the thickness direction coincides with the Y direction.

  Note that the plate-shaped member storage container according to the embodiment of the present invention has a configuration in which a plurality of guide grooves 4 for guiding the plate-shaped member 8 to the inner bottom surface 5 are provided on all of the two opposing inner surfaces 3. May be. Even in such a configuration, the plate-like member 8 is formed in the opening 2 along the guide groove 4 included in any one of the two inner surfaces 3 having the guide groove 4. It is possible to insert the plate-shaped member 8 by inserting it toward the inner bottom surface 5.

  Here, the plate-shaped member storage container according to the present embodiment is characterized in the configuration of the inner side surface 3 in which the guide groove 4 is formed. As shown in (b) and (c) of FIG. 2, the pair of opposing inner side surfaces 3 provided with the guide grooves 4 each have an uneven shape. The concavo-convex shape of the inner side surface 3 is configured by a bottom surface that forms the guide groove 4, a set of inner side surfaces 7 (second inner side surface), and a surface on the inner side surface 3 where the guide groove 4 is not formed. Yes. The above-mentioned bottom surface of the guide groove 4 is a surface with which the side surface of the plate-like member 8 to be accommodated contacts, and is the bottom surface side inner surface 3a (first bottom surface side inner surface) located on the innermost bottom surface 5 side, and the inclined surface 3b. (First inclined surface) and an opening side inner side surface 3c (first opening side inner side surface) located closest to the opening 2 side. Moreover, the inner side surface 7 of the guide groove 4 is a surface with which the surface or back surface of the plate-shaped member 8 accommodated contacts. Moreover, the surface in which the guide groove 4 is not formed in the inner surface 3 is a surface which the plate-shaped member 8 accommodated does not contact, and has the inclined surface 3d (4th inclined surface).

  The inclined surface 3 b is inclined so that the distance between the pair of inner side surfaces 3 increases from the inner bottom surface 5 toward the opening 2. More specifically, the two inclined surfaces 3 b formed on the set of inner side surfaces 3 are inclined in a tapered shape at an inclination angle θa with respect to the normal line L of the outer bottom surface 12. The inclined surface 3b is not limited to a tapered shape.

  The bottom side inner side surface 3 a has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12. Further, the opening side inner side surface 3c has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12. That is, the bottom side inner side surface 3 a and the opening side inner side surface 3 c are formed to be parallel to the normal line L. In other words, the bottom-side inner side surface 3 a and the opening-side inner side surface 3 c are planes perpendicular to the outer bottom surface 12. Here, “the inclination angle with respect to the normal L is 0 °” means that the inclination angle with respect to the normal L is 0 ° within the design range of integral molding or within the measurement range of the inclination angle. More specifically, the inclination angle of the bottom side inner side surface 3a and the opening side inner side surface 3c with respect to the normal L is 0 ± 0.5 °, preferably 0 ° ± 0.3 °, more preferably. Is 0 ° ± 0.1 °. Note that the absolute value of the tilt angle is smaller than a tilt angle θa described later.

  When the opening-side inner side surface 3c has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12, the plate-like member 8 is inserted along the guide groove 4 from the opening 2 toward the inner bottom surface 5. Further, by inserting the side surface of the plate-like member 8 facing the inner side surface 3 against the opening side inner side surface 3c, the Z-direction positioning at the start of insertion can be easily performed.

  In the plate-like member storage container according to the present embodiment, the set of inner side surfaces 7 (second inner side surfaces) that form the guide grooves 4 are formed so as to be line symmetric. As shown in FIG. 2C, the set of inner side surfaces 7 includes a bottom side inner side surface 7a (second bottom side inner side surface) and an inclined surface 7b ( 2nd inclined surface), and the opening side inner side surface 7c (2nd opening side inner side surface) most located in the opening part 2 side. The inner surface 7 is a surface facing the front surface or the back surface of the plate member 8 when the plate member 8 is inserted into the guide groove 4 and accommodated in the main body 1A.

  The inclined surfaces 7 b are inclined so that the distance between the pair of inner side surfaces 7 increases from the inner bottom surface 5 toward the opening 2. More specifically, the two inclined surfaces 7 b formed on the set of inner side surfaces 7 are inclined in a tapered shape at an inclination angle θb with respect to the normal L of the outer bottom surface 12. The inclined surface 7b is not limited to a tapered shape.

  The bottom side inner side surface 7 a has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12. Further, the opening side inner side surface 7c has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12. That is, the bottom side inner surface 7 a and the opening side inner surface 7 c are formed to be parallel to the normal line L. In other words, the bottom-side inner side surface 7 a and the opening-side inner side surface 7 c are planes perpendicular to the outer bottom surface 12. Here, “the inclination angle with respect to the normal L is 0 °” means that the inclination angle with respect to the normal L is 0 ° within the design range of integral molding or within the measurement range of the inclination angle. More specifically, the inclination angle of the bottom side inner side surface 7a and the opening side inner side surface 7c with respect to the normal L is 0 ± 0.5 °, preferably 0 ° ± 0.3 °, more preferably. Is 0 ° ± 0.1 °. Note that the absolute value of the tilt angle is smaller than the tilt angle θb described later.

  The surface where the guide groove 4 is not formed on the inner side surface 3 will be described. When viewed from the direction shown in FIG. 2C, this surface is a surface sandwiched between adjacent guide grooves 4, and has at least one inclined surface 3d (fourth inclined surface). As shown in FIG. 2B, in the set of inner side surfaces 3 facing each other, the inclined surfaces 3 d become wider as the distance between the inclined surfaces 3 d increases from the inner bottom surface 5 toward the opening 2. Further, the outer bottom surface 12 is inclined at an inclination angle θc with respect to the normal L. More specifically, as shown in FIG. 2 (b), the pair of opposed inclined surfaces 3d has an inclination angle θc1 and θc2 with respect to the normal L of the outer bottom surface 12 from the opening 2 to the inner bottom surface 5. Inclined in a tapered shape. Note that the inclined surface 3d is not limited to a configuration inclined in a tapered shape.

  When the opening-side inner surface 7c is inclined at 0 ° with respect to the normal L of the outer bottom surface 12, the plate-like member 8 is inserted from the opening 2 toward the inner bottom surface 5 along the guide groove 4. In addition, the insertion in the Y direction at the start of insertion can be easily performed by inserting the plate-like member 8 after the front surface or the back surface side is in contact with the opening side inner surface 7c.

  Further, as shown in FIG. 2B, the outer surface 6 of the main body 1A is widened so that the interval between the outer surfaces 6 arranged at the opposing positions increases from the inner bottom surface 5 toward the opening 2. It is inclined. More specifically, the outer side surface 6 is formed so as to be inclined in a tapered shape that spreads outward as it goes from the inner bottom surface 5 toward the opening 2.

  Further, the material of the main body 1A is not particularly limited. For example, the main body 1A may be a foam molded body obtained by in-mold foam molding from foamed particles of a thermoplastic resin. The inner side surface 3, the inner bottom surface 5 and the support groove 4a of the main body 1A may be integrally formed, or may be combined after being formed separately. More preferably, the main body 1A is an integrally molded product.

  There is no restriction | limiting in particular in the kind of expanded particle of the said thermoplastic resin, and the manufacturing method of the said expanded particle, A conventionally well-known expanded particle and manufacturing method can be mentioned. As an example of the production method, when the foamed particles of the thermoplastic resin are polyolefin resin foamed particles, the production disclosed in International Patent Publication Nos. WO2009 / 075208 and JP-A-2006-117842, etc. In the case of polystyrene resin expanded particles, the production methods disclosed in Japanese Patent Application Laid-Open Nos. 2003-2013360 and 2014-118474 are listed (in the patent document, The foamed particles of the thermoplastic resin are described as “pre-foamed particles”), and in the case of styrene-modified polyolefin resin foamed particles, the production method disclosed in Japanese Patent Application Laid-Open No. 2008-239794, etc. Although it is mentioned, it is not limited to these.

  In the expanded particles obtained by the production method described above, additives such as a flame retardant, an antistatic agent and a colorant can be appropriately contained or coated by a conventionally known method. Further, the particle size of the foamed particles is not particularly limited, and is preferably 1 mm to 10 mm, for example, but from the viewpoint of mold filling, it is more preferably 1 mm to 5 mm, and 1 mm to 3 mm. More preferably.

  The expansion ratio of the expanded particles is not particularly limited and is preferably, for example, 3 to 90 times, but more preferably 5 to 60 times from the viewpoint of mechanical strength and moldability. More preferably, it is 5 to 30 times.

  Such expanded particles are commercially available, for example, as Eperan-PP and Eperan-XL manufactured by Kaneka Corporation, and are easily available.

  As a method for producing the main body 1A as a foam molded body using the above-described thermoplastic resin foam particles, an in-mold foam molding method can be adopted, which is described in JP-A-2001-79870 and the like. Conventionally known molding methods can be employed. For example, (1) First, a pair of molds consisting of a concave mold and a convex mold is closed to form a molding space, and (2) foam particles are fed from the raw material tank into the molding space through a filler, and filled. (3) Next, the foamed particles in the molding space are heated with water vapor so that the foamed particles are fused and integrated, and then cooled, and (4) a pair of molds are opened and foamed in the mold. The method of taking out a molded object is mentioned.

(About the effect of the plate-shaped member storage container which concerns on this embodiment)
FIG. 3 is a diagram for explaining the function and effect of the plate-shaped member storage container according to the present embodiment. FIG. 3A is an inner side surface 3 ′ of the main body 1A ′ in the conventional plate-shaped member storage container. FIG. 3B is a cross-sectional view showing the configuration of the inner side surface 3 of the main body 1A in the plate-like member storage container according to the present embodiment. However, in the main body 1A ′ and the main body 1A shown in FIGS. 3A and 3B, the second inner side surface 7 is omitted and not shown. FIG. 3C is a diagram showing the configuration of the guide groove 4 ′ formed on the inner side surface 3 ′, and FIG. 3D shows the configuration of the guide groove 4 formed on the inner side surface 3. FIG.

  In the plate-shaped member storage container according to this embodiment, as described above, the bottom side inner side surface 3a of the set of inner side surfaces 3 in which the guide grooves 4 are formed has an inclination angle of 0 ° with respect to the normal L. That is, the bottom side inner side surface 3 a is formed to be parallel to the normal line L. Thereby, when the plate-shaped member 8 is accommodated in the main body 1A, movement in the Z direction (in other words, wobble) is suppressed. For this reason, the plate-like member 8 can be stably held in the main body 1A. As a result, it is possible to prevent contact and breakage between the plate-like members 8 when a plurality of plate-like members 8 are accommodated and the plate-like member storage container is transported.

  Note that, in the plate-shaped member storage container according to the embodiment of the present invention, one of the inner surfaces 3 of the set of inner surfaces 3 formed with the guide grooves 4 has an inclination angle of 0 ° with respect to the normal L. The structure which has a certain bottom face side inner surface 3a may be sufficient. Even in such a configuration, when the plate-like member 8 is accommodated in the main body 1A, movement in the Z direction (in other words, wobble) can be suppressed, so that the plate-like member 8 is stably held in the main body 1A. Has the advantage of being able to.

  As shown in FIG. 3A, in the conventional plate-shaped member storage container, the inner side surface 3 ′ in which the guide groove 4 ′ is formed in the main body 1A ′ is inclined from the opening at an inclination angle θa with respect to the normal L. It has a tapered shape that is uniformly inclined to the inner bottom surface. In such a configuration, the distance between the plate-like member 8 accommodated in the main body 1A 'and the inner side surface 3' increases from the inner bottom surface toward the opening. For this reason, when the plate-shaped member 8 is accommodated in the main body 1 </ b> A ′, a space in which the plate-shaped member 8 can move in the Z direction is formed. Therefore, in the conventional configuration, it cannot be said that the plate-like member 8 can be stably held in the main body 1A '.

  On the other hand, as shown in FIG. 3B, in the plate-shaped member storage container according to the present embodiment, the bottom side inner side surface 3 a in the set of inner side surfaces 3 in which the guide grooves 4 are formed has a normal L Since the inclination angle with respect to is 0 °, the plate-like member 8 is in contact with the bottom side inner side surface 3a of the inner side surface 3 and moves outward from the bottom side inner side surface 3a even if it moves in the main body 1A. There is nothing. That is, the bottom side inner side surface 3a of the inner side surface 3 functions as a locking surface that locks the movement of the plate member 8 in the Z direction in the main body 1A. In addition, although the space | interval of the bottom surface side inner surface 3a in a set of inner surface 3 can be suitably set according to the environment (degree of vibration etc.) at the time of conveyance of the plate-shaped member storage container 10, the plate-shaped member 8 is set. A value closer to the dimension in the Z direction is more preferable. When the space | interval of the bottom side inner side surface 3a is the same as the dimension of the Z direction of the plate-shaped member 8, since the plate-shaped member 8 is hold | maintained more firmly, it is preferable.

  Here, the main body of the plate-shaped member storage container is an integrally molded product. In general, when a container-shaped article such as the main body 1A or 1A ′ is manufactured by molding with a mold such as a foamed molded body, it is removed from the mold for easy release from the mold. A slope called a slope is formed. If no draft is formed in the mold, it is difficult to release the mold. The inner side surface 3 ′ or the inclined surface 3 b shown in FIG. 3 (a) or (b) is a surface formed by this draft angle.

  When the inner side surface 3 ′ is uniformly inclined due to the draft angle of the mold at the time of molding like the main body 1 </ b> A ′ of the conventional plate-shaped member container, it is easy to release the mold from the mold at the time of molding. On the other hand, as described above, the plate-like member 8 cannot be held sufficiently. That is, in the conventional configuration, the inner side surface 3 ′ is usually inclined due to the draft angle of the mold at the time of molding, so that stable holding and accommodation of the plate-like member 8 and good moldability are compatible. It was difficult.

  As a result of intensive studies to solve the above-described problems, the inventors have (1) a bottom-side inner side surface 3a that provides stable holding of the plate-like member 8 on the inner side surface 3 of the main body 1A, and (2) gold. By forming the inclined surface 3b that provides easy release from the mold, the plate-like member storage container 10 that can solve the above-described problems has been provided. That is, the plate member 8 can be stably held, and the plate member container 10 that can be easily released from the mold has been provided.

  That is, the main body 1A of the plate-shaped member container 10 has the inclined surface 3b due to the draft of the mold and the bottom-side inner side surface 3a considered to be difficult to release from the normal mold. By forming for the purpose of holding, stable holding and accommodation of the plate-like member 8 and good moldability are achieved. In order to achieve such a balance, the X-direction dimension of the surface having the inclination angle of 0 ° with respect to the normal L such as the bottom side inner surface 3a and the opening side inner surface 3c and the inclined surface 3b is accommodated in the main body 1A. Depending on the size of the plate-like member 8 to be selected, it can be appropriately selected. More specifically, it will be described below.

  When the size of the plate-like member 8 is a width (dimension in the Z direction) 100 mm to 750 mm, a height (dimension in the X direction) 100 m to 500 mm, and a thickness (dimension in the Y direction) 0.5 mm to 0.7 mm. The size (outside dimension) of the main body 1A is preferably in the following range. The width (dimension in the Z direction, outer dimension) of the main body 1A is preferably (width of the plate-like member 8) +30 mm or more and (width of the plate-like member 8) +90 mm or less, more preferably (plate-like member). 8 width) +40 mm or more and (width of plate-like member 8) +80 mm or less, particularly preferably (width of plate-like member 8) +50 mm or more and (width of plate-like member 8) +70 mm or less. The height (dimension in the X direction, outer dimension) of the main body 1A is preferably (height of the plate-like member 8) ÷ 2 + 10 mm or more and (height of the plate-like member 8) ÷ 2 + 50 mm or less, more preferably (Height of plate-like member 8) ÷ 2 + 20 mm or more and (height of plate-like member 8) ÷ 2 + 40 mm or less, particularly preferably (height of plate-like member 8) ÷ 2 + 25 mm or more and (plate-like member) (Height of 8) ÷ 2 + 35 mm or less. The thickness (dimension in the Y direction, outer dimension) of the main body 1A depends on the number of plate members and is appropriately set. The bottom thickness of the main body 1A is preferably 10 mm or more and 50 mm or less, more preferably 20 mm or more and 40 mm or less, and particularly preferably 25 mm or more and 35 mm or less.

  There is no particular limitation on the height of the inner side surface 3 (the dimension in the X direction when orthographically projected onto the XY plane including the inner side surface 3, hereinafter also referred to as “bottom height”), but the height of the plate-like member 8 30 to 70% is preferable, 40 to 65% is more preferable, and 50 to 61% is most preferable. In such a case, the stability when inserting and transporting the plate-like member 8 is improved.

  In the plate-shaped member storage container according to the embodiment of the present invention, when the inner side surface 3 is composed of the bottom side inner side surface 3a and the inclined surface 3b, the size of the bottom side inner side surface 3a in the X direction and the X of the inclined surface 3b. There is no particular limitation on the dimension in the direction (dimension in the X direction when the inclined surface 3b is projected onto the XY plane). However, the size of the bottom side inner surface 3a in the X direction is preferably 16 to 33%, more preferably 19 to 30%, and most preferably 21 to 27% with respect to the bottom height. In addition, the dimension of the inclined surface 3b in the X direction is preferably 67 to 84%, more preferably 70 to 81%, and most preferably 73 to 79% with respect to the bottom height. In such a case, it becomes easy to hold the plate-like member 8 stably, and the releasability from the mold when the plate-like member storage container is foam-molded in the mold tends to be good.

  In one embodiment of the present invention, from the viewpoint of further improving the stability of the plate-like member 8 and the releasability from the mold when the plate-like member receiving container is subjected to in-mold foam molding, The side surface 3 is more preferably configured to include an opening side inner side surface 3c in addition to the bottom side inner side surface 3a and the inclined surface 3b. In this case, the dimension in the X direction of the bottom side inner surface 3a is preferably 16 to 33%, more preferably 19 to 30%, and most preferably 21 to 27% with respect to the bottom height. The dimension of the inclined surface 3b in the X direction is preferably 34 to 68%, more preferably 40 to 62%, and most preferably 46 to 58% with respect to the bottom height. Further, the dimension in the X direction of the opening side inner surface 3c is preferably 16 to 33%, more preferably 19 to 30%, and most preferably 21 to 27% with respect to the bottom height.

  The size in the X direction of the bottom side inner side surface 3a is preferably equal to the size in the X direction of the opening side inner side surface 3c. The reason for this is that when the main body 1A is subjected to in-mold foam molding, the bottom side with respect to the parting line (the line in which the male mold and female mold constituting the mold used for in-mold foam molding are divided) This is because it is presumed that the resistance at the time of mold release is further reduced by simultaneously removing the portions of the inner side surface 3a and the opening side inner side surface 3c from the mold. Since there is little resistance at the time of mold release from a metal mold | die, it becomes easy to suppress a deformation | transformation of a molded object.

  FIG. 3C is a diagram showing the configuration of the guide groove 4 ′ formed on the inner side surface 3 ′, and FIG. 3D shows the configuration of the guide groove 4 formed on the inner side surface 3. FIG.

  As shown in FIG. 3C, in the conventional plate-shaped member housing container, a set of inner side surfaces 7 ′ forming the guide grooves 4 ′ in the main body 1 </ b> A ′ are parallel to the normal line L. In such a configuration, when manufactured as a foamed molded article, in a normal molding method, releasability from a mold is remarkably poor, and moldability is poor.

  On the other hand, as shown in FIG. 3 (d), in the plate-shaped member container according to the present embodiment, as described above, the pair of inner side surfaces 7 that form the guide grooves 4 are closest to the inner bottom surface 5 side. It has a bottom-side inner side surface 7a positioned, an inclined surface 7b inclined in a tapered manner at an inclination angle θb with respect to the normal L, and an opening-side inner side surface 7c positioned closest to the opening 2 side. The bottom side inner side surface 7a has an inclination angle of 0 ° with respect to the normal L. That is, the bottom side inner side surface 7 a is formed to be parallel to the normal line L. Further, the inclined surface 7b is a surface formed by a draft angle of the mold at the time of molding. Thereby, when the plate-like member 8 is accommodated in the main body 1A, even if it moves in the main body 1A, the plate-like member 8 is brought into contact with the bottom side inner side surface 7a of the inner side surface 7, so that the movement in the Y direction is suppressed. . That is, the bottom side inner surface 7a functions as a locking surface that locks the movement of the plate member 8 in the Y direction in the main body 1A. For this reason, the plate-like member 8 can be stably held in the main body 1A. As a result, it is possible to prevent contact and breakage between the plate-like members 8 when a plurality of plate-like members 8 are accommodated and the plate-like member storage container is transported. Further, since the inclined surface 7b is formed by the draft of the mold, the releasability from the mold during molding is good.

  In the plate-like member storage container according to the embodiment of the present invention, one of the inner side surfaces 7 that forms the guide groove 4 has an inclination angle of 0 ° with respect to the normal L. The structure which has the bottom side inner surface 7a may be sufficient. Even in such a configuration, when the plate-like member 8 is accommodated in the main body 1A, movement in the Y direction (in other words, wobble) can be suppressed, so that the plate-like member 8 is stably held in the main body 1A. Has the advantage of being able to.

  In addition, although the space | interval of the bottom surface side inner surface 7a in a set of inner surface 7 can be suitably set according to the environment (degree of vibration, etc.) at the time of conveyance of a plate-shaped member storage container, A value closer to the dimension (thickness) in the Y direction is more preferable. When the space | interval of the bottom surface side inner surface 7a is the same as the dimension of the Y direction of the plate-shaped member 8, since the plate-shaped member 8 is hold | maintained more firmly, it is preferable.

  In the present embodiment, stable holding and accommodation of the plate-like member 8 and good moldability are compatible with the inner surface 7 that forms the guide groove 4. For this purpose, the X-direction dimension of the inclined surface 7b and the surface having an inclination angle of 0 ° with respect to the normal L such as the bottom-side inner surface 7a and the opening-side inner surface 7c are accommodated in the main body 1A. Depending on the size of the plate-like member 8 to be selected, it can be appropriately selected. More specifically, it will be described below.

  In the plate-shaped member storage container according to the embodiment of the present invention, when the inner side surface 7 is composed of the bottom side inner side surface 7a and the inclined surface 7b, the dimension in the X direction of the bottom side inner side surface 7a and the X of the inclined surface 7b. There is no particular limitation on the dimension in the direction (dimension in the X direction when the inclined surface 7b is projected onto the XZ plane). However, the dimension in the X direction of the bottom side inner surface 7a is preferably 16 to 33%, more preferably 19 to 30%, and most preferably 21 to 27% with respect to the bottom height. Further, the X-direction dimension of the inclined surface 7b is preferably 67 to 84%, more preferably 70 to 81%, and most preferably 73 to 79% with respect to the bottom height. In such a case, it becomes easy to hold the plate-like member 8 stably, and the releasability from the mold when the plate-like member storage container is foam-molded in the mold tends to be good.

  In the present invention, from the viewpoint of further improving the stability of the plate-like member 8 and the releasability from the mold when the plate-like member storage container is subjected to in-mold foam molding, the inner side surface 7 is: In addition to the bottom side inner side surface 7a and the inclined surface 7b, it is more preferable to include an opening side inner side surface 7c. In this case, the dimension in the X direction of the bottom side inner surface 7a is preferably 16 to 33%, more preferably 19 to 30%, and most preferably 21 to 27% with respect to the bottom height. The dimension of the inclined surface 7b in the X direction is preferably 34 to 68%, more preferably 40 to 62%, and most preferably 46 to 58% with respect to the bottom height. Moreover, 16 to 33% is preferable with respect to the said bottom height, as for the dimension of the X direction of the opening part side inner surface 7c, 19 to 30% is more preferable, and 21 to 27% is the most preferable.

  As a specific example, the plate-like member 8 has a width (dimension in the Z direction) of 550 mm, a height (dimension in the X direction) of 322 mm, and a thickness (dimension in the Y direction) of 0.5 to 0.7 mm. And about the case where 40 such plate-shaped members 8 are accommodated, the dimension of each member of the plate-shaped member accommodation container which concerns on this embodiment is illustrated below.

  The main body 1A preferably has a width (dimension in the Z direction) 610 mm, a height (dimension in the X direction) 220 mm, and a thickness (dimension in the Y direction) 608 mm.

  In this case, the distance between a pair of opposing bottom side inner surfaces 3a (in other words, the inner dimension of the main body 1A in the Z direction) is preferably 553 mm, and the thickness of the bottom of the main body 1A is It is preferably 25 mm.

  The bottom height is preferably 195 mm, which is about 60.6% of the height of the plate member 8.

  The inner side surface 3 preferably includes a bottom side inner side surface 3a, an inclined surface 3b, and an opening side inner side surface 3c, and the dimensions are as follows. The dimension in the X direction of the bottom side inner surface 3a is preferably 50 mm, which is about 25.6% of the bottom height. The dimension of the inclined surface 3b in the X direction is preferably 95 mm, which is about 48.7% of the bottom height. The dimension in the X direction of the opening side inner surface 3c is preferably 50 mm, which is about 25.6% of the bottom height.

  Moreover, it is preferable that the inner surface 7 contains the bottom face side inner surface 7a, the inclined surface 7b, and the opening part side inner surface 7c, and each dimension is as follows. The dimension in the X direction of the bottom side inner surface 7a is preferably 50 mm, which is about 25.6% of the bottom height. The dimension of the inclined surface 7b in the X direction is preferably 95 mm, which is about 48.7% of the bottom height. The dimension in the X direction of the opening side surface 7c is preferably 50 mm, which is about 25.6% of the bottom height.

  Moreover, it is preferable that the distance (in other words, it can be said that the inner dimension of the guide groove 4 in the Y direction) between the pair of opposed bottom side inner surfaces 7a is 2 mm.

  Further, the width (dimension in the Z direction) of the bottom side inner surface 7a is preferably about 11 mm, and the width (dimension in the Z direction) of the inclined surface 7b is preferably about 9 mm. The width of the side surface 7c (dimension in the Z direction) is preferably about 7 mm. However, these widths change depending on the inclination angle θc of the inclined surface 3d, and may not be constant.

  The inclination angle θa of the inclined surface 3b with respect to the normal L of the outer bottom surface 12 is preferably 1 °.

  Moreover, it is preferable that the inclined surface 7b inclination | tilt angle (theta) b with respect to the normal line L of the outer bottom face 12 is 1 degree.

  The inclination angle of the outer surface 6 with respect to the normal L is preferably 1 °.

  Moreover, when the main body 1A has the opening side outer surface 6a, the opening side outer surface 6a is preferably 50 mm.

  The dimension in the X direction of the bottom side inner surface 7a is preferably equal to the dimension in the X direction of the opening side inner surface 7c. The reason for this is that when the main body 1A is subjected to in-mold foam molding, the parting line (the line in which the male mold and female mold constituting the mold used for in-mold foam molding are divided) is simultaneously removed from the mold. This is because it is presumed that the resistance at the time of mold release is further reduced by coming off. When there is little resistance at the time of mold release from a metal mold | die, it will become easy to suppress a deformation | transformation of a molded object.

  Further, the inclination angle θa of the inclined surface 3b on the inner side surface 3 and the inclination angle θb of the inclined surface 7b on the inner side surface 7 are angles related to the draft angle of the mold during molding. Considering release from the mold, the inclination angle θa and the inclination angle θb are preferably greater than 0 ° and 10 ° or less, more preferably 0.5 ° to 5 °, and 0.6 It is more preferable that the angle is 3 °, and it is particularly preferable that the angle is 0.6 ° to 1 °.

  Further, the inclination angle θc of the inclined surface 3d on the inner side surface 3 is an angle related to the draft angle of the mold during molding. Although there is no restriction | limiting in particular in inclination | tilt angle (theta) c, From the viewpoint that it becomes possible to hold | maintain the plate-shaped member 8 stably and it can be easily released from a metal mold | die, it is 0.6 degrees-5.0 degrees. Preferably there is. The inclined surface 3d may have a plurality of inclination angles θc. For example, as shown in FIG. 2B, when the inclined surface 3d has two inclination angles θc (θc1 and θc2), θc1 = 2.2 ° and θc2 = 1.1 °. . In FIG. 2B, θc1 is larger than θc2, but is not limited to this. That is, when the inclined surface 3d has a plurality of inclination angles θc, there is no particular limitation on the magnitude relationship between the plurality of inclination angles θc.

  Moreover, the inclination angle with respect to the normal L of the outer surface 6 shown in FIG. 2B is preferably greater than 0 ° and 10 ° or less, more preferably 0.5 ° to 5 °, and 0 The angle is more preferably from 6 ° to 3 °, and particularly preferably from 0.6 ° to 1 °.

As shown in FIG. 4, the outer surface 11 of the lid body 1 </ b> B has an opening side outer surface 11 a and at least one inclined surface 11 b (third inclined surface). The opening-side outer surface 11a has an inclination angle of 0 ° with respect to the normal L shown in FIG. That is, it is formed parallel to the normal line L.

  When the lid 1B closes the opening 2 of the main body 1A, the inclined surface 11b is formed so that the interval between the outer surfaces 11 is inclined toward the opening 2. This inclined surface 11b is a surface formed by the draft angle of the mold at the time of molding.

  Moreover, since the opening side outer surface 11a has an inclination angle of 0 ° with respect to the normal L shown in FIG. 2B, when two or more plate-shaped member storage containers 10 are arranged adjacent to each other, Positioning of the plate-shaped member storage containers 10 is facilitated by placing the opening-side outer surfaces 11a of the adjacent plate-shaped member storage containers 10 in contact with each other. As a result, the plate-shaped member storage container 10 can be stably disposed.

  The shape of the lid 1B can be appropriately selected depending on the shapes of the main body 1A and the plate-like member 8, but the lid 1B has a shape capable of fitting into the opening 2 of the main body 1A and closing the main body 1A. Preferably it is. The lid 1B may have a shape such that the main body 1A is rotated 180 degrees with respect to the opening 2. In other words, the lid body 1 </ b> B may be provided with a surface having the same structure as the inner surface 3, the inner bottom surface 5, and the outer surface 6 provided on the main body 1 </ b> A.

  The material of the lid body 1B is not particularly limited. For example, the lid body 1B may be a foam molded body formed by in-mold foam molding from foamed particles of a thermoplastic resin, like the main body 1A. When the lid body 1B is provided with surfaces having the same structure as the inner side surface 3, the inner bottom surface 5 and the outer side surface 6 provided on the main body 1A, these may be integrally molded or separately molded. Later, they may be combined. More preferably, the lid body 1B is an integrally molded product. The lid 1B may be the same material as the main body 1A or may be different.

  The types of thermoplastic resin foam particles used for the production of the lid 1B and the production method of the foam particles include conventionally known foam particles and production methods as described in the section of the (main body 1A) described above. be able to.

  As a method for producing the lid body 1B as the foam molded body using the foamed particles of the thermoplastic resin, a conventionally known molding method as described in the above section (main body 1A) can be exemplified.

  Further, the inner bottom surface 5 may be formed in a taper shape with respect to the normal L of the outer bottom surface 12 so as to go to the inner side of the main body 1A (inner side in the Y direction and / or inner side in the Z direction). The tapered portion (in other words, the inclined surface) may have one inclination angle or a plurality of inclination angles. That is, the inclined surface of the inner bottom surface 5 may be uniformly inclined at a constant angle, or may be inclined stepwise with a plurality of inclination angles. By having the said structure, it becomes possible to accommodate the plate-shaped member 8 which has various height in one main body 1A.

That is, the opening side outer surface 6 a is formed in parallel to the normal line L.

  When two or more plate-shaped member storage containers are arranged adjacent to each other by forming the opening-side outer surface 6a on the pair of opposed outer surfaces 6, the main body of the adjacent plate-shaped member storage containers By positioning the opening-side outer surfaces 6a of 1E in contact with each other, the positioning of the main bodies 1E of the plate-shaped member storage containers is facilitated. As a result, there is an advantage that the plate-like member storage container can be stably arranged.

  Further, in the main body 1E of the plate-shaped member storage container, a non-contact groove 9 that does not contact the bottom portion of the plate-shaped member 8 is provided at a contact portion between the inner bottom surface 5 and the inner surface 3 where the guide groove 4 is provided. It may be.

It is a figure which shows a part of. In addition, in the structure shown to (a)-(c) of FIG. 6, the BB line used as the cutting | disconnection reference | standard of "BB line arrow sectional drawing" is the BB line shown to (a) of FIG. It is the same. In the plate-shaped member storage container according to the present embodiment, the configuration of the inner side surface 7 constituting the guide groove 4 is different from that of the first embodiment.

  In the configuration shown in FIG. 6A, the inner side surface 7 constituting the guide groove 4 has a bottom side inner side surface 7a and an inclined surface 7b. It is not the structure which has the opening part side inner surface 7c like the said 1st Embodiment. Even with such a configuration, the plate-like member 8 can be stably held and can be easily released from the mold.

  Further, in the configuration shown in FIG. 6B, the inner side surface 7 constituting the guide groove 4 has two inclined surfaces 7b. Even with such a configuration, the plate-like member 8 can be stably held and can be easily released from the mold. In addition, the number of the inclined surfaces 7b should just be at least one, and is not limited to two.

  Further, in the configuration shown in FIG. 6C, two opposing inner side surfaces 7 constituting the guide groove 4 have at least a bottom side inner side surface 7a and an inclined surface 7b. One of the inner surfaces 7 has an opening side inner surface 7c. That is, these two inner surfaces are not symmetrical with each other. Even with such a configuration, the plate-like member 8 can be stably held and can be easily released from the mold.

The first inner side surface 3 is provided with a plurality of guide grooves 4 for guiding the plate-like member 8 to the inner bottom surface 5, and the set of first inner side surfaces 3 is the first inner side surface. 3 has at least one first inclined surface 3b that is inclined so as to increase from the inner bottom surface 5 toward the opening 2, and at least one of the pair of first inner surfaces 3 The first bottom surface side inner surface 3a located closest to the inner bottom surface 5 side of the first first inner surface 3 has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12.

  By having the said structure, it has the following advantages: (1) Among a set of 1st inner surface 3 which opposes, at least one 1st inner surface 3 has the bottom face side inner surface 3a, The movable distance (in other words, wobble) in the main body 1A of the accommodated plate-like member 8 can be reduced. Thereby, since the plate-like member 8 can be stably held in the main body 1A, when the plate-like member 8 is accommodated and the plate-like member accommodating container 10 is transported, the plate-like members 8 are brought into contact with each other and damaged. (2) Furthermore, when the pair of opposing first inner side surfaces 3 have the inclined surfaces 3b, when the main body 1A is molded with a mold or the like, the separation from the mold is possible. The mold becomes easy and the moldability becomes good.

  In the plate-shaped member storage container 10 according to an embodiment of the present invention, the first inner side surface 3 of the set of first inner side surfaces 3 is located closest to the opening 2 side in at least one first inner side surface 3. It is preferable that 1 opening side inner side surface 3c is 0 degree with respect to the normal L of the outer bottom surface 12.

  When the plate-shaped member container 10 has the above-described configuration, the following advantages are obtained: (1) The plate-shaped member 8 is inserted along the guide groove 4 from the opening 2 toward the inner bottom surface 5. Sometimes, the positioning at the start of insertion can be easily performed by inserting the side surface of the plate-like member 8 against the inner side surface 3c on the opening side; (2) Further, the positioning in the above (1) When the side surface of the plate-like member 8 and the inner surface 3c on the opening side are in contact with each other, the corner of the plate-like member 8 and the inner side surface 3 are in contact with each other (for example, the opening side is an inclined surface). 3b), the impact on the contact surface of the plate-like member 8 is small. Accordingly, it is possible to suppress damage to the plate-like member 8.

  In the plate-like member storage container 10 according to an embodiment of the present invention, at least one first inner side surface 3 of the set of first inner side surfaces 3 includes the first bottom side inner side surface 3a and It is preferable to have both of the first opening side inner surface 3c.

  When the plate-shaped member 8 is inserted from the opening 2 toward the inner bottom surface 5, the plate-shaped member 8 is guided after the side surface of the plate-shaped member 8 is applied to the opening-side inner surface 3c for positioning at the start of insertion. In addition to the groove 4, it is inserted along the opening side inner side surface 3 c, the inclined surface 3 b, and the bottom side inner side surface 3 a on the same inner side surface 3.

As described above, the contact between the corners of the plate-like member 8 and the inclined surface 3b is a plate as compared with the contact between the surface (side surface) of the plate-like member 8 and the bottom side inner side surface 3a and the opening side inner side surface 3c. The possibility of damage to the shaped member 8 increases. When at least one inner side surface 3 of the set of opposing inner side surfaces 3 has both the bottom side inner side surface 3a and the opening side inner side surface 3c, the set of opposing inner side surfaces 3 is the bottom side inner side surface. The dimension in the X direction of the inclined surface 3b of the inner side surface 3 is shorter than that in the case of having either one of 3a or the opening side inner side surface 3c. Therefore, when at least one inner side surface 3 of the set of inner side surfaces 3 has both the bottom side inner side surface 3a and the opening side inner side surface 3c, contact between the corners of the plate-like member 8 and the inclined surface 3b. There is an advantage that it is possible to suppress damage to the plate-like member 8 when the plate-like member 8 is inserted due to the above.

  In the plate-like member storage container 10 according to an embodiment of the present invention, the set of first inner side surfaces 3 includes both the first bottom side inner side surface 3a and the first opening side inner side surface 3c. It is preferable to have.

The movable distance (in other words, wobble) can be reduced. Thereby, since the plate-like member 8 can be stably held in the main body 1A, when the plate-like member 8 is accommodated and the plate-like member accommodating container 10 is transported, the plate-like members 8 are brought into contact with each other and damaged. (2) Since the pair of opposed first inner side surfaces 3 have the inclined surfaces 3b, when the main body 1A is molded with a mold or the like, the mold can be released from the mold. (3) Since the set of opposed inner side surfaces 3 has both the bottom side inner side surface 3a and the opening side inner side surface 3c, the dimension of the inclined surface 3b in the X direction is short. Become. Accordingly, it is possible to suppress damage to the plate-like member 8 when the plate-like member 8 is inserted due to contact between the corners of the plate-like member 8 and the inclined surface 3b.

  In the plate-like member storage container 10 according to an embodiment of the present invention, the pair of second inner side surfaces 7 that form the guide grooves 4 are such that the distance between the second inner side surfaces 7 that face each other is the inner bottom surface. 5, at least one second inclined surface 7 b that is inclined so as to become wider toward the opening 2, and at least one second inner surface 7 of the set of second inner surfaces 7. It is preferable that the second bottom surface side inner surface 7a located closest to the inner bottom surface 5 has an inclination angle of 0 ° with respect to the normal L of the outer bottom surface 12.

  By having the above configuration, the following advantages are obtained: (1) The gap in the Y direction of the guide groove 4 on the opening 2 side is widened, and the plate-like member 8 can be easily inserted; Since at least one second inner side surface 7 of the second inner side surfaces 7 has the bottom side inner side surface 7a, the movable distance in the main body 1A of the plate-like member 8 can be reduced. Thereby, since the plate-like member 8 can be stably held in the main body 1A, when the plate-like member 8 is accommodated and the plate-like member accommodating container 10 is transported, the plate-like members 8 are brought into contact with each other and damaged. (3) Furthermore, when the pair of opposing second inner side surfaces 7 has the second inclined surface 7b, the mold 1A is molded with a mold or the like. Release from the mold becomes easy, and the moldability becomes good.

At this time, the surface (front surface side or back surface side) of the plate-like member 8 is in contact with the opening-side inner side surface 7c and the bottom-side inner side surface 7a, and the corner of the plate-like member 8 is in contact with the inclined surface 7b. As described above, the contact between the corners of the plate-like member 8 and the inclined surface 7b is the contact between the surface (front side or back side) of the plate-like member 8, the bottom-side inner side surface 7a, and the opening-side inner side surface 7c. In comparison, the possibility of damage to the plate-like member 8 increases. In the case where at least one inner side surface 7 of the set of opposed inner side surfaces 7 has both the bottom side inner side surface 7a and the opening side inner side surface 7c, the set of opposed inner side surfaces 7 is the bottom side inner side surface. The dimension in the X direction of the inclined surface 7b of the inner side surface 7 is shorter than in the case of having only one of the inner side surface 7c and the opening side inner surface 7c. Therefore, when at least one inner surface 7 of the set of inner surfaces 7 has both the bottom-side inner surface 7a and the opening-side inner surface 7c, the contact between the corners of the plate-like member 8 and the inclined surface 7b.

It becomes possible. Therefore, it becomes possible to prevent contact and breakage between the plate-like members 8; (2) In addition to the guide groove 4 provided on the inner surface 3, the plate-like member 8 is further held by the support groove 4a. Even when the size of the member 8 is large, it is possible to prevent the plate-like member 8 from being inserted obliquely, for example, by mistakenly entering the guide groove 4 adjacent to the corresponding guide groove 4. That is, when the plate-like member 8 is inserted into the guide groove 4, the larger the width direction of the plate-like member 8 is, the larger the width of the plate-like member 8 is. It becomes easy to erroneously insert (incorrectly) into the other guide groove 4 that is shifted from the guide guide 4 to the next. However, by providing the support groove 4a, the bottom portion of the plate-like member 8 is not well accommodated in the support groove 4a even if it is erroneously inserted. Therefore, before inserting another plate-like member 8 and / or before moving the main body 1A, it is possible to correctly insert the plate-like member 8 that has been misinserted.

  The plate-like member storage container 10 according to an embodiment of the present invention further includes a lid 1B that closes the opening 2, and the pair of opposed outer surfaces 11 in the lid 1B are the outer surfaces 11 to each other.
