Description

  The present invention relates to a transport container used for transport and storage of glass plates for liquid crystal displays and plasma displays, glass substrates for touch panels and other thin plate-like bodies in addition to the base plate glass.

  Conventionally, a container body and a lid made of a synthetic resin foam having a buffering property as a transport container for storing and transporting a plurality of relatively large glass substrates for liquid crystal display or plasma display in parallel A supporting groove consisting of longitudinal grooves is formed at equal intervals on the inner surface of one opposing side wall of the container body, and the side edges of the glass substrate are inserted into the supporting grooves to mutually A device that is supported and stored so as not to contact is known.

  Further, in addition to providing a bottom pad having a support groove comprising a lateral groove for protecting the lower end portion of the glass substrate on the bottom plate in the container main body, the upper end portion of the glass substrate protruding above the container main body is protected. It has also been proposed to provide a top pad having a support groove formed of a lateral groove (for example, Patent Documents 1 and 2). Since the top pad needs to fit the upper end of the glass substrate into the support groove during the deposition operation, it covers the upper end of the glass substrate separately from the lid, and then the lid is deposited. I am doing so.

  By the way, in recent years, the thinning of the glass substrate has progressed. For example, a glass substrate of about 0.7 mm is used for a liquid crystal display panel, and a very thin glass substrate of about 0.3 mm is used for a touch panel. Has been. In order to protect such a glass substrate when it is transported, even when a transport container provided with a buffered grooved bottom pad, top pad, or the like is used, the thinner the glass substrate, the easier it is to bend and deform. In some cases, damage to the glass substrate is increasing.

  This problem is caused by the deformation of the container itself due to external factors such as vibration during transportation and impact due to contact with other objects, in addition to the increase in deflection due to vibration during transportation due to the thinning of the glass substrate. The inner glass substrate is greatly bent or rattled, causing the groove on the left and right side walls holding the glass substrate or the groove from the bottom pad or top pad support groove to occur, It is considered that the major cause is that the glass substrates interfere and contact each other.

  This point will be described. As shown in FIGS. 14 and 15, in the transport container including the bottom pad 106 and the top pad 104, the lid 103 is fitted on the upper end of each side wall 112 (112 a, 112 b) of the container body 101. Generally, it is in the form of being attached, but due to play of this fitting part, it is easily affected by vibrations during transportation and impact due to contact with other objects, and the side wall of the container body 101 In particular, the side wall 112a facing the plate surface of the plate-like body B such as the housed glass substrate tends to be bent and deformed inward with respect to the lid 102.

  That is, outward deformation of the side wall 112 of the container body 101 with respect to the lid 103 is restricted by the lid 103, and inward deformation of the left and right side walls 112b having the support grooves 113 is suppressed to the plate-like body B. Although it is restricted by itself, the side wall 112a facing the plate surface of the plate-like body B has no portion that restricts inward deformation, and is therefore bent inward due to vibration or external impact. There is a risk.

  If the deformation occurs such that the side wall 112a is displaced inward relative to the lid body 103 or the lid body 103 is displaced outward relative to the side wall 112a, as shown in FIG. There is a deviation between the position of the support groove 155 of the top pad 104 mounted on the lower surface of the top plate and the position of the support groove 113 on the inner surface of the side wall of the container body 101, and as a result, the support groove 113 and 155 are fitted. Thus, the plate-like body B held in parallel at a constant interval is greatly bent, and the plate-like body B is likely to be damaged due to detachment or interference.

  Therefore, as this type of transport container, as described above, when both side ends and upper and lower ends of a plate-like body such as a glass substrate are inserted into a support groove and supported in parallel at a fixed interval, the groove It is desired to prevent the detachment from occurring easily and to suppress the bending deformation of the upper end portion of the side wall of the container body.

  In order to solve such a problem of the plate-shaped transport container, the ends that are opened laterally on both sides corresponding to the side walls having the supporting grooves and are fitted into the upper ends of the side walls on the other opposite sides. Using an inner lid with a wall and fitting and attaching the inner lid fitted with a top pad with a support groove between both end walls to the container body, the upper and lower side walls of the container body are bent and deformed. It has been proposed to regulate the above (Patent Document 3).

  In the case of the proposal, the inner lid regulates the inward bending deformation of the upper end portion of the side wall where the end walls of both sides are fitted, and includes the entire upper end portion of the container body including the supporting groove. However, it is not satisfactory enough to suppress the bending deformation.

  Further, since the inner lid on which the top pad is mounted as described above is held inside the lid body, the lid body becomes deep and bulky, and the upper end of the stored plate-like body is placed on the inner lid. Since the top plate pad is held by the top plate pad, the upper end of the stored plate-like body protrudes upward higher than the container body, and therefore when the lid and the inner lid are removed, The upper end portion is exposed in a protruding state, and other objects can easily come into contact.

On the lower surface, convex portions 55 having the support grooves 54 are formed at both ends in the opening direction so as to define one concave portion 56, and one plate-like one as the top pad 4 is formed in each concave portion 56. The pad piece 41 can also be attached. When the inner lid 5 is attached to the plate-like body B stored in parallel in the container body 1 by using the inner lid member 50a divided into two parts as described above, each plate-like body is used. The alignment of the support groove 54 with respect to B and the fitting and attaching work are facilitated, which is more preferable in practice.

  The top pad 4 or each pad piece 41 as the top pad is a buffer such as a soft synthetic resin foam that is more flexible than the container body 1, the lid 3, and the inner lid 5, like the bottom pad 6. When the concave portion 56 is made of a material, the lower surface thereof is located slightly below the groove bottom within the range of the groove depth of the support groove 54 of the convex portion 55, for example, 1 from the groove bottom to the groove depth. / 3 to 1/5 has a flat plate shape having a predetermined thickness set so as to be in the position of about 3 to 1/5. In the attached state of the inner lid 5, the support groove 54 of the convex portion 55 The upper end of the plate-like body B that is fitted and supported is elastically contacted.

  As the mounting means for the top pad 5, for example, the top pad 4 or each pad piece 41 for each of the inner lid 5 or the inner lid member 50a may be simply fitted and held in the recess 56. Fitting means by concaves and convexes that engage with each other can be provided on the peripheral side surface of the recess 56 and the outer peripheral surface of each top pad 4 or pad piece 41 so that they can be fitted so as not to be easily removed. This engagement structure can also be applied to the bottom pad 6 described above. An adhesive means can also be used.

  Although it is possible to form a support groove for supporting the upper end of the plate-like body B in the top pad 4 (not shown), in this case, the convex portion 55 on the lower surface of the inner lid 5 is formed. It is assumed that the height of the top pad 4 is reduced and the thickness of the top pad 4 is increased, and a support groove is formed in a portion protruding downward from the convex portion 55. In practice, as shown in the figure, the support groove 54 is provided in the convex portion 55 integral with the inner lid 5 so that it can be molded with almost no error from the support groove 13 on the inner surface of the side wall. It is particularly preferred because it is not affected by shrinkage after molding. Furthermore, the inner lid 5 can be implemented by holding the upper end portion of the plate-like body B only by the support groove 54 of the convex portion 55 without using the top pad 4. However, from the viewpoint of the protective effect of the plate-like body B, it is desirable that the top pad 4 be mounted as in the illustrated embodiment.

  Moreover, although the case where the cover body 3 was externally fitted to the side wall upper end portion of the container main body 1 was shown in the above-described embodiment, the present invention is similar to the embodiment of FIGS. However, the present invention can be similarly applied to a container of a type that is internally fitted to the upper end of the side wall of the container body 1. In this embodiment, the same components and parts as those in the first embodiment are given the same reference numerals and detailed description thereof is omitted.

  In this embodiment, as a fitting structure of the lid 3 to the container main body 1, the upper end of the side wall of the container main body 1, that is, the upper end of the four side walls 12a and 12b is cut out on the inner side and used for the outer side fitting. A notch 34 is formed on the lower surface of the peripheral edge of the top plate 31 of the lid 3, and the top plate portion inside the notch 34 is the container body. 1 is provided so as to be fitted into cutout portions 25a and 25b formed inside the one projecting edge 24.

  Further, the inner lid 5 can be fitted so that the respective sides 51a and 51b of the four circumferences are placed on the stepped surface by the cutout portions 25a and 25b below the lid 3, but the illustrated embodiment In this case, the projecting edges 52a and 52b formed on the side end surfaces of the four side portions 51a and 51b of the plate body constituting the inner lid 5 are the notched portions 25a and 25b of the side walls 12a and 12b of the container body 1, respectively. It is provided so as to be fitted to the positioning notch step portions 26a and 26b formed on the step surface portion by the above, and thereby, the effect of suppressing the bending deformation of the side walls 12a and 12b can be satisfactorily exhibited. Yes. In particular, when the protrusions 52a and 52b are fitted to each other, when the one side wall 12a or 12b of the container body 1 is bent and deformed inwardly, the notch step portion 22b or 22a of the other side wall 12b or 12a is formed. Further, the displacement of the inner lid 5 to which the projecting edge 52b or 52a is fitted is suppressed, so that the inward deformation of the side wall 12a or 12b can be suppressed. In addition, the arrangement form, the number, and the like of the protruding edges 52a and 52b in the inner lid 5 can be configured and implemented in the same manner as in the first embodiment.

  In the transport container A of each embodiment described above, the support groove 13 on the left and right side walls 12b, 12b of the container body 1, the support groove 54 for supporting the upper end portion of the plate-like body B on the lower surface of the inner lid 5, and The supporting groove 18 that supports the lower end of the plate-like body B at the bottom 11 of the container body 1 has a tapered shape with the opening end side spreading in a V-shape, and the distance between both inner surfaces is constant on the groove bottom side. It is also assumed that a groove-shaped shape with a width gap is formed, and that both inner side surfaces have a taper shape that extends continuously from the groove bottom to the open end in a V-shape on one surface.

  The container body 1 and the lid 3 can be made of any foamed resin molding, such as polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer, etc. Polystyrene resins such as polyethylene resins, polyolefin resins such as polyethylene, polypropylene, and ethylene-vinyl acetate copolymers, and foams of various synthetic resins such as 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. The foaming ratio of the foam is preferably 3 to 50 times.

  The inner lid 5 is also basically made of the same foam having the same shape retention and elasticity as the lid 3. For example, when the lid 3 and the inner lid 5 are made of the same material, a foam having the same expansion ratio as that of the lid 3 is basically used as the inner lid 5.

  Also, the top pad 4 and the bottom pad 6 are the same synthetic resin bead-molded foams as described above, and are mainly slightly more flexible than the container body 1, the lid body 3, and the inner lid 5, and have shape retention and elasticity. A synthetic resin foam having properties is used.

  In the use of the transport container A of the above-described embodiment, the bottom pad 6 (each pad piece 61) is disposed in the concave portion 17 between the convex portions 16 on the upper surface of the bottom portion 11 of the container body 1, and the inner lid 5 The top pad 4 (each pad piece 41) is arranged and attached to the concave portion 56 between the convex portions 55, 55 on the lower surface.

  Then, in the storing operation of the plate-like body B, the side end portion of the plate-like body B is inserted into the support groove 13 provided on the left and right side walls 12b, 12b of the container body 1, and the side end portion is slid. Then drop it to the bottom 11 and store it. At this time, the lower end corner portion of the plate-like body B such as the glass substrate to be accommodated extends inwardly at the convex step portion 15 on the upper surface of the bottom portion 11 with the lower end portion of the supporting groove 13. The bottom pad of the plate-like body B is easily fitted and supported without being detached from the support groove 18 in each of the inward convex portions 16 while the lower end portion of the plate-like body B is bent and regulated. 6 is elastically received and protected.

  In this way, on the plate-like body B accommodated in parallel at a fixed interval corresponding to the support groove 13, the flat inner cover 5 having the top pad 4 mounted thereon as described above is provided on the lower surface thereof. The position of the support groove 54 of the plate-like portion 55 is aligned with the upper end portion of the plate-like body B, and the upper end portion of the plate-like body B is fitted into the support groove 54, while Mates inside. When the side edges 51a and 51b of the four circumferences have the protruding edges 52a and 52b, the protruding edges 52a and 52b are fitted to the positioning notch steps 22a and 22b having the inner side of the upper end of the side wall of the container body 1. By doing so, the inner lid 5 is positioned and held at a predetermined position. Thereafter, the lid 3 is fitted on the inner lid 5 by being externally fitted to the upper end of the side wall of the container body 1. A band (not shown) is attached to the outside of the packaged container as necessary for transportation.

  Also in the case of the transport container A of the embodiment of FIGS. 10 to 13 in which the lid 3 is internally fitted to the container main body 1, similarly to the above, the flat plate-like inner lid 5 with the top pad 4 is attached to the lower surface thereof. The upper end of the side wall of the container main body 1 is fitted while aligning the position of the support groove 54 of the convex portion 55 with the upper end of the plate-like body B and fitting the upper end of the plate-like body B into the support groove 54. The projecting edges 52a and 52b of the respective sides 51a and 51b of the four circumferences are fitted into the notch portions 25a and 25b on the inner side of the portion, or into the notch step portions 26a and 26b formed on the step surface by the notch portions 26a and 26b By joining, the inner lid 5 is positioned and held at a predetermined position. Thereafter, the lid 3 is fitted on the inner lid 5 by being externally fitted to the upper end of the side wall of the container body 1. A band (not shown) is attached to the outside of the packaged container as necessary for transportation.

  In either case, the four sides of the inner lid 5 are fitted inside the upper ends of the four side walls 12a and 12b of the container body 1 (for example, FIG. 5). The inner lid 5 can prevent inward bending deformation of the upper end of the side wall, and can also prevent deformation of the container main body 1 into a parallelogram. For this reason, it is possible to prevent the glass substrate from being bent and detached from the groove during handling during transportation and transportation.

  In particular, at least one of the inner lids, preferably projecting edges 52a, 52b provided on the side end surfaces of the opposing side portions 51a, 51b are formed on the inner side of the upper end of the side wall of the container body 1. When fitted into 22a, 22b or 26a, 26b, the front / rear / left / right movement of the inner lid 5 can be restricted. For example, one of the longitudinal and lateral side walls 12a or 12b of the container body 1 tends to bend and deform inward. At the time, the displacement of the inner lid 5 in which the protruding edge 52b or 52a is fitted to the notch step portion 22b or 22a of the other side wall 12b or 12a can be restricted, and consequently the inward deformation of the side wall 12a or 12b is suppressed. It will be possible. Therefore, it is possible to effectively prevent the upper end portion of the plate-like body B from separating from the support groove 54, the support groove 54 provided on the lower surface of the inner lid 5, and the support groove 13 on the inner surface of the side wall of the container body 1. There is no deviation in the relative position.

  Moreover, since the inner lid 5 is fitted inside the upper end of the side wall of the container main body 1, the upper end of the plate-like body B housed in the container main body 1 protrudes upward from the container main body 1. In addition, when the lid 3 and the inner lid 5 are removed, the upper end portion of the plate-like body B is not exposed, and there is no possibility that other objects easily come into contact.

  Accordingly, there is no occurrence of large bending or detachment in the plate-like body B fitted in the support groove 13 and held in parallel at a constant interval, and the glass substrates accompanying the large deformation of the plate-like body B Damage due to the interference can be prevented, and as a result, the plate-like body B can be made thinner.

  The transport container of the present invention can be suitably used for transporting and storing raw plate glass, glass substrates for liquid crystal displays and plasma displays, fairly thin glass substrates for touch panels, and other various plate-like bodies that are vulnerable to impact.
