Description

  The present invention relates to a plate-like container for transporting and storing various glass substrates such as glass plates for glass, liquid crystal displays and plasma displays, and other plate-like bodies. .

  Conventionally, as a transport container for storing and transporting a plate-like glass, a relatively large glass substrate such as a glass substrate for liquid crystal display, or a panel such as a solar battery panel or other impact-sensitive plate-like body, it is buffered. One plate-like body is formed in a longitudinal groove arranged 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 in an upright state so as not to contact each other are stored.

  In recent years, due to an increase in demand for large-sized liquid crystal televisions and plasma televisions, large-sized glass substrates in which one or both of the vertical and horizontal directions exceed 100 cm have been adopted as glass substrates for televisions. Transport containers for transport are also becoming larger.

  However, in the conventional method of accommodating the glass substrate in an upright state by the vertical groove on the inner surface of the side wall, the glass substrate itself is bent and deformed by its own weight because of the large and heavy glass substrate, or the weight of the glass substrate is a container. When the load is concentrated on the bottom of the main body, 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, glass substrates and protective sheets are alternately stacked and stored in a flat state in the container body, and each glass substrate is protected. A container for transportation that has been received on the surface via the sheet has also appeared.

  As described above, in the case of a transport container that stores and stacks plate-like bodies such as glass substrates in a horizontal state, at least the four side walls of the container body are arranged so that the horizontal plate-like bodies can be easily stored and taken out. Often, notched recesses for storing and removing operations in the vertical direction from the upper end of the side wall to the bottom are formed on the inner surfaces of the opposite side walls.

  On the other hand, as shown in Patent Documents 1 to 3, the lid body is attached to the container body at the opening end at the upper end of the side wall of the container body, leaving a convex edge on the outside. A notch step is formed, and on the lower surface of the peripheral portion of the lid body, a fitting wall portion that is fitted to the notch step outside the convex edge at the opening end of the container body is suspended. It is common. For this reason, the notch recessed part for storage and taking-out operation formed in the side wall inner surface of a container main body is open | released by the upper end of the said protruding item | line edge.

  At this time, there is no problem if the side wall and the protruding strip edge have a sufficient thickness, but if the side wall and the protruding strip edge cannot have a sufficient thickness, a notch opened above the protruding strip edge. When the concave portion is formed, a thin wall portion remains on the outer peripheral side of the ridge, and the thin wall portion cannot have sufficient strength, and is easily broken or damaged in handling. .

  For this reason, the cutout recess is formed by opening it outward so as not to leave a thin wall portion in the protruding edge portion of the upper end portion.

  In this case, as shown in FIG. 13, in the state where the fitting wall portion 132 of the lid body 103 is fitted to the notch step portion 113 outside the protruding edge 112 and the lid body 103 is attached to the container body 101. The horizontal surfaces of the notch step portion 113 and the lower end of the fitting wall portion 132 are in contact with each other outside the open portion 118a of the notch recess 118, and the sealing performance of this portion is poor. There is a risk that dust or the like may enter from the gap between the contact portions.

  That is, in a portion other than the notch recess 118, a vertical contact between the outer surface of the ridge 112 and the inner surface of the fitting wall 132 from a horizontal contact portion between the notch step 113 and the lower end of the fitting wall 132. 3, and further, the contact portion between the upper end surface of the convex edge 112 and the contact portion between the top plate lower surface of the lid body 103 and the refracted three contact surface portions can ensure a sufficient sealing performance. At 118, there is only a horizontal contact surface between the notch step portion 113 and the lower end of the fitting wall portion 132, and a gap is likely to occur at this contact portion, so that the sealing performance is inferior to the other portions. , The intrusion prevention effect such as dust is not obtained,

A container to be transported, wherein a notch step portion is formed on the outer side of the opening end of the upper end of the side wall of the container body, leaving a convex edge on the inner side, and a convex edge at the opening end portion on the peripheral edge of the lid. In the transporting container in which a fitting wall part that fits into the outer notch step part is vertically provided, the inner surface of at least one opposite side wall of the container main body is projected from the convex edge part of the upper end of the side wall. A notch recess for storing and taking out operation reaching the upper surface of the bottom is provided, and the convex edge portion at the upper end of the notch recess is notched and opened to the outside. The upper end of the notch recess that fits into the notch recess inside the fitting wall Shielding wall for closing the open portion of the outwardly at is characterized by comprising projecting.

  According to this transport container, when a plate-like body such as a glass substrate is stacked and stored in a horizontal state and transported, the fitting wall portion of the lid is fitted to the opening end of the container body and attached. In this state, the fitting wall portion of the lid body is fitted to the outside of the convex edge of the opening end portion of the container body, and the shielding wall suspended from the lid body in the notch recess formed in the inner surface of the side wall Even if the fitting ridge is cut out at the upper end of the notch recess and opened outward, the open portion of the upper end of the notch recess is shielded by the fitting of the shielding wall. It can be held in a closed state, and entry of dust and the like can be prevented.

  In the transport container for the plate-like body, the outer portion of the opening portion of the notch recess in the notch step portion of the container body, and the outer portion of the shielding wall in the fitting wall portion of the lid body, It is preferable to provide a protective contact surface portion that prevents the intrusion of dust by inclining or refracting the contact surfaces that face each other when the lid is attached. As a result, in addition to the outwardly open portion of the notch step portion being shielded and blocked by the shielding wall, the contact surface that is abutted with each other at the outer notch step portion and the fitting wall portion portion. Since the protective contact surface portion is inclined or refracted, it has a good sealing property and can further enhance the effect of preventing the entry of dust and the like.

  In the transport container of the plate-like body, the notch step portion of the container body is provided with a notch portion having an inclination or a step that becomes lower toward the outer surface side as the defense contact surface portion, and the fitting of the lid body is performed. The mating wall portion may be provided with a protruding portion that fits into the notch portion.

  Further, as the defensive contact surface portion, a notch step portion of the container body is provided with a convex portion having an inclination or a step which becomes higher toward the inner surface side, and the convex portion is fitted to the fitting wall portion of the lid body. It can also be provided with a recessed portion.

A notch part to be fitted is provided, and a convex part fitted to the inside of the convex wall is provided.

  In any of these protective contact surface portions, the outer portion of the notch recess in the notch step portion of the container body and the outer portion of the shielding wall in the fitting wall portion of the lid are mutually connected. It is possible to form a defensive contact surface portion in which the contact surfaces to be abutted are inclined or refracted, thereby ensuring good sealing performance and enhancing the effect of preventing entry of dust or the like at the location of the notch recess.

  As described above, according to the container for transporting a plate-like body of the present invention, the shielding wall that fits into the notch recess also at the location of the notch recess for storing and taking out operation provided on the inner surface of the side wall of the container body. Therefore, it is possible to maintain a good sealing property and to prevent entry of dust and the like. In particular, by providing a protective contact surface portion that is inclined or refracted with the contact surfaces that are abutted against each other when the lid is attached to the outer portion of the notch recess and the shielding wall, it is possible to ensure even better sealing performance. Therefore, it is possible to reliably prevent the entry of dust and the like from the notch recess, and to satisfactorily protect the stored plate-like body.

  Therefore, when the side wall of the container body forms a notch recess for private and take-out operations on its inner surface, it may leave a sufficient thickness in the convex edge portion for fitting at its upper end. Even if it is not possible, it can be implemented by forming the notch recess without problems, and it is also possible to easily change the inner dimension according to the size of the plate-like body to be stored while leaving the outer dimension unchanged.

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

  FIGS. 1-10 has shown one Example of the container for conveyance of the plate-shaped body concerning this invention. The transport container A of this embodiment is a flat rectangular shape that opens upward and can store a plate-like body B such as a glass substrate to be stored in a state where the plate-like bodies are stacked with a protective sheet for spacers interposed therebetween. Or a square flat rectangular container body 1 and a lid 3 that can be attached to the container body 1.

  As an attachment structure of the lid body 3 to the container body 1, the opening end portion 11 at the upper end of the side wall of the container body 1 is formed with a notched step portion 13 on the outside, leaving a convex edge 12 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 into and comes into contact with the notch step portion 13 outside the convex edge 12 at the opening end portion 11 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 buffering property, and a storage space is formed by the four side walls 15a, 15b, 15c, and 15d rising from the bottom portion. The storage space is formed to a depth that allows the required number of plate-like bodies B stacked via a protective sheet to be stored. Usually, although it changes also with the thickness of the plate-shaped body B, in the case of the plate-shaped body B, such as a glass substrate of thickness 2-5 mm, for example, it forms relatively shallowly so that about 10 to several dozen sheets can be accommodated.

  A vertical notch 16 is formed inside the corner portion by the four side walls 15a, 15b, 15c, 15d of the container body 1, and the upper surface 14a of the bottom portion 14 serving as a receiving surface of the plate-like body B is formed. At the four corners including the notch 16, there are provided recesses 17 for avoiding contact of the corner b 1 of the plate-like body B stored on the bottom 14. The concave portion 17 is formed by being dropped about 5 to 15 mm with respect to the upper surface 14a. Thereby, in a normal storage state, the corner b1 of the plate-like body B stored on the bottom portion 14 does not contact the side walls 15a, 15b, 15c, 15d due to the notch 16, and The corner b1 of the lowermost plate-like body B is in a state of floating at the concave portion 17 so as not to contact the bottom 14.

  In the case of the illustrated embodiment, the bottom surface 17a of the recess 17 is gradually inclined downward from the edge on the side continuous with the inner edge, that is, the upper surface 14a of the bottom 14, toward the outer edge, that is, the edge on the connection side with the side wall. Even when a large deformation is caused in the corner portion of the container body 1 due to vibration or dropping during transportation or handling, the plate-like body B can be The corner b1 is not in contact with the bottom surface 17a of the recess 17.

  In the case of the present invention, at least one of the opposite side walls of the four side walls 15a, 15b, 15c, 15d of the container body 1, for example, the inner surfaces of the long side walls 15a, 15c as shown in the figure. Are provided with at least one notch recess 18 for storing and taking out the plate-like body B having a groove shape in the vertical direction at a required portion such as a central portion in the longitudinal direction of the side. In the case of the figure, a notch recess 18 having a groove shape with a required depth from the upper end of the side wall to the bottom 14 is formed on two inner surfaces at intervals in the longitudinal direction of the side walls 15a and 15c on the long side. Yes. Accordingly, when the plate-like body B is stored and taken out, the fingertip can be hung under the lowermost plate-like body B by being inserted at the notch recess 18 or mechanically engaged. The stop means can be inserted up to the portion on the bottom portion 14 so as to be locked under the lowermost plate-like body B. Therefore, the cut-out recess 18 is formed with an extension that extends from the upper end of the side wall to the bottom 14 and enters the inner side of the bottom 14 slightly at the lower end.

  In consideration of the thickness of the side walls 15a, 15b, 15c, and 15d and the thickness of the projecting edge 12, the notch recess 18 is formed by notching the portion of the projecting edge 12 at the upper end to open outward. The Reference numeral 18a denotes an outwardly opened portion.

  One or more notch recesses similar to those described above can also be formed on the other short side wall 15b, 15d (not shown), but in the case of the illustrated embodiment, On the inner surfaces of the side walls 15b and 15d, vertical concave grooves 19 are formed at a required interval in order to prevent the short side edge of the plate-like body B from contacting the inner surface of the side wall over the entire length. Further, if necessary, an abutting member made of an elastic material is provided on the inner surface of each of the side walls 15a, 15b, 15c, 15d, and the edge of the plate-like body B is abutted and held on the abutting member. You can also. In this case, the recesses 17 at the four corners are formed so as to include a portion where the corner b1 of the plate-like body B to be stored is located.

  The lid 3 is formed of a synthetic resin foam having a cushioning property similar to that of the container main body 1, and as described above, the lid 3 is fitted to the ridge 12 for fitting the opening end 11 of the container main body 1. It is provided so that it can be attached by fitting the wall 32.

  And in the part corresponding to the notch recess 18 for storing and taking out the side wall inner surface of the container main body 1 on the lower surface of the peripheral edge portion 31 of the lid 3, the lid 3 is attached to the container main body 1. A shielding wall 33 that fits into the notch recess 18 is suspended along the inner side of the fitting wall portion 32, and the shielding wall 33 fits into the notch recess 18, whereby the notch recess 18. Is provided so as to shield and close the outwardly open portion 18a. As a result, a good sealing property can be maintained even in the open portion 18a of the cutout recess 18 of the container body 1, and entry of dust or the like from the cutout recess 18 can be prevented.

  A portion outside the open portion 18a of the notch recess 18 in the notch step portion 13 of the container body 1 and a portion outside the shielding wall 33 in the fitting wall portion 32 of the lid 3 are the other portions. Similarly, it may be just abutted and brought into contact with each other in a horizontal plane. In this case, the inner surface of the notch recess 18 is shielded from the horizontal contact portion between the notch step portion 13 and the fitting wall portion 32. Since it is only continuous with the vertical contact portion with the vertical surface of the wall 33, dust or the like may enter through the gap between the contact portions. Therefore, in practice, the notch step portion 13 outside the open portion 18a. A protective contact surface portion 20 that prevents the intrusion of dust by inclining or refracting each other's contact surface is provided at the contact portion between this portion and the portion of the fitting wall portion 32 outside the shielding wall 33. preferable. The contact portion can be tilted or refracted in various shapes, but in practice, it has a portion that is inclined or refracted upward from the outside to the inside to prevent dust from entering. It is particularly preferable from the viewpoint of effect.

  As the defensive contact surface portion 20, as shown in the figure, the notch step portion 13 of the container body 1 is provided with a notch portion 21 having a shape that is inclined or stepped down toward the outer surface side. The mating wall portion 32 may be provided with a protruding portion 34 that fits into the cutout portion 21. In the case of the figure, as the notch portion 21, the entire area corresponding to the thickness (width) of the notch step portion 13 in the inner and outer directions can be inclined, but the remaining portion inside the container of the notch portion 21 is triangular at the upper end. Since the protrusion 34 having a shape corresponding to this has a triangular shape at the lower end on the outer side, each has a problem in strength, as shown in the figure, the notches 21 are arranged on the inner surface side and the outer surface side of the container. It is preferable that the intermediate portion is formed as an inclined surface 21b while leaving the horizontal surfaces 21a and 21a having a little width, and the protrusion 34 has a shape corresponding to the notch 21.

  As the protective contact surface portion 20, in addition to the above, as shown in FIG. 11, the notch step portion 13 of the container main body 1 is provided with a convex portion 22 that forms an inclination or a step that becomes higher toward the inner surface side. The third fitting wall portion 32 may be provided with a recessed portion 35 into which the convex portion 22 is fitted. In this case, the inclined surface of the convex portion 22 can be a steeply inclined surface that is nearly perpendicular to the notch step portion. Further, as shown in FIG. 12, the notch step portion 13 of the container body 1 is provided with a convex wall 23 surrounding the outwardly open portion 18 a of the notch recess portion 18, and the fitting wall portion 32 of the lid body 3 is provided with the convex wall 23. May be provided with a notch portion 36 into which the convex wall 23 is fitted, and a convex portion 37 to be fitted inside the convex wall 23. In any of these cases, the contact portion between the portion of the notch step portion 13 and the portion of the fitting wall portion 32 outside the shielding wall 33 has an inclined or refracted contact surface, thereby preventing dust from entering. The effect can be exhibited well. In particular, in the embodiment of FIGS. 1 to 10 and the embodiment of FIG. 11, the contact portion forms a contact surface that is inclined or refracted upward from the outside to the inside. It will be expensive.

  Further, in the above-described transport container A, at least one side of the container body 1 facing each other, preferably the notch step portions 13 of the side walls 15a, 15b, 15c, 15d on each side, and each side of the lid body 2 are arranged. At least one concave portion 28a, 28b or convex portion 38a, 38b that is fitted to each other when the lid is attached is formed at the lower end portion of the side fitting wall portion 32. The concave portion 28a, 28b and the convex portion 38a, 38b are formed. Is provided so that the displacement movement of the lid 3 in the attached state can be regulated. In the illustrated embodiment, the notch step portion 13 of the opening end portion 11 of the container body 1 is provided with inverted trapezoidal concave portions 28 a and 28 b having both sides tapered, and the lower end portion of the fitting wall portion 32 of the lid 3.

Various synthetic resins such as polystyrene resins, polyolefin resins such as polyethylene, polypropylene, and ethylene-vinyl acetate copolymers, and polyester resins such as polyethylene terephthalate can be used. Especially, the molded object by the bead foam of a styrene modified polyolefin resin is used suitably. The styrene-modified polyolefin resin is obtained by impregnating and polymerizing a polyolefin resin particle with a styrene monomer. Among the styrene-modified polyolefin resins, a styrene-modified polyethylene resin is preferable, for example, a styrene component The ratio is 40 to 90% by weight, preferably 50 to 85% by weight, more preferably 55 to 75% by weight. The foaming ratio of the foam is preferably 3 to 50 times.

  The molded product of the styrene-modified polyolefin resin bead foam is stronger than the molded product of the polypropylene resin beads having the same expansion ratio, and the shrinkage rate when a container having a depth exceeding 500 mm is molded. Low dimensional accuracy. Furthermore, there is an advantage that powder due to rubbing is less likely to be produced as compared with foamed molded products of styrene resin beads.

  According to the above-described container A for transporting a plate-like body, the plate-like body B such as a base plate glass and a glass substrate for liquid crystal display is accommodated. At this time, the protective sheet C and the plate-like body B for spacers having a thickness of 0.2 to 5.0 mm are alternately stacked and stored on the bottom 14 in the container body 1. As the protective sheet C, a soft synthetic resin foam sheet, for example, a polyolefin resin foam sheet, is preferably used.

  After the plate-like body B is stored as described above, the lid 3 is attached to the container body 1. At this time, the fitting wall portion 32 of the lid body 3 is fitted to the opening end portion 11 of the container body 1, and at the same time, the shielding wall 33 provided on the lower surface of the lid body 3 is cut out for storing and taking out the plate-like body.
