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, for example A supporting groove consisting of vertical grooves is formed at equal intervals on the inner surface of one opposite side wall of the container main body, and the side edges of the glass substrate are inserted into the supporting grooves. What is supported and stored so as not to come into contact with the battery 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).

  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, and the groove on the right and left side walls supporting the glass substrate or the groove from the bottom pad and the top pad support groove is generated, and as a result, It is considered that the major cause is that the glass substrates interfere and contact each other.

  Therefore, when both sides of the glass substrate and the upper and lower ends of the glass substrate are inserted into the support groove and supported in parallel at a predetermined interval as described above, support is made so as not to easily cause the separation of the groove. Of course, it is possible to support the glass substrate with stability, but especially when storing the glass substrate, the lower end of the glass substrate is inserted into the support groove on both side walls of the container body from above and dropped down. It is desired to easily and surely fit into the supporting groove in the.

  For example, in the storing operation of the glass substrate, the side end portion of the glass substrate is inserted into the supporting groove on the inner surface of the side wall of the container body from the upper end opening, and dropped along the supporting groove. The lower end of the glass substrate is supported by being fitted in a supporting groove having a lower end, and at this time, the thinner the glass substrate is, the easier it is to bend and deform. There is a risk that the support groove on the upper surface of the bottom portion may be displaced, and even if the storage operation is performed while gazing from the upper end opening of the container main body, it is extremely troublesome. When the groove width of the support groove is reduced according to the thickness of the glass substrate, the fitting operation is more difficult to perform.

  The present invention has been made to solve the above problems, and when a plate-like body such as a thin glass substrate is stored in a container body, both side ends thereof are vertically supported on the inner wall of the container body. Thin glass used for touch panels that can be easily inserted into the horizontal support groove having the lower end of the plate-like body on the upper surface of the bottom so as to be inserted and dropped into the groove. Even in the case of a substrate, it is possible to easily carry out the storage operation, and to provide a plate-like container that can satisfactorily protect a plate-like member such as a glass substrate.

  The present invention for solving the above problems is a flat rectangular container made of a synthetic resin foam for containing and transporting a plate-like body, the upper surface is open, and the inner surfaces of one opposite side walls A container body provided with a plurality of vertical support grooves for supporting the side edges of the plate-like body, a bottom pad disposed on the bottom upper surface of the container body, and a top edge of the side wall of the container body. In a plate-shaped transport container comprising a cover body to be attached together, a lateral auxiliary groove extending inwardly on the upper surface of the bottom continuously from the lower end of the vertical support groove. It is formed and is provided so as to continuously support the lower end corner portion of the plate-like body from the supporting groove in the vertical direction by the auxiliary groove on the upper surface of the bottom portion.

  As described above, the transport container according to the present invention is continuously formed with the lateral auxiliary grooves extending from the lower ends of the longitudinal support grooves on the inner surfaces of the both side walls of the container body toward the inner surface of the bottom portion. Therefore, during the storing operation of the plate-like body such as the glass substrate, the lower end corner portion of the plate-like body inserted into the vertical support groove and dropped is formed on the bottom upper surface continuous with the vertical support groove. The auxiliary groove is fitted without causing a deviation, and this serves as a guide to suppress the bending of the lower end portion of the plate-like body, and also to the supporting groove set inward of the upper surface of the bottom portion. It will fit securely without slippage. Therefore, even if the plate-like body is quite thin, the storing operation can be easily performed.

  In the transport container of the plate-like body, convex stepped portions are provided at both end portions on the side wall side having the vertical supporting grooves on the upper surface of the bottom, and the convex stepped portions are continuous from the vertical supporting grooves. A lateral auxiliary groove is formed, and a bottom pad for receiving and supporting a lower end portion of the plate-like body supported by the auxiliary groove is provided between the convex stepped portions. Thereby, the lower end part of the plate-like body fitted in the auxiliary groove of the convex step part is supported by the inner bottom pad without contacting the bottom part.

  In the transport container of the plate-like body, the vertical support grooves and the auxiliary grooves on the inner surface of the side wall are arranged in parallel with the auxiliary grooves on the inner surface of the side wall at a predetermined interval inward from the convex stepped portions at the both ends of the upper surface of the bottom. The convex part which has the groove | channel for several horizontal directions to be provided is provided, and the bottom pad dividedly formed in plurality by the recessed part between each convex part shall be installed. In this case, as described above, the auxiliary groove on the upper surface of the bottom continuous with the supporting groove in the vertical direction can be easily and surely fitted into the supporting groove of the convex portion on the inside of the bottom. The effect of holding by the supporting groove can be greater than that of the groove formed in the bottom pad, and the plate-like body can be supported more stably.

  In the plate-shaped conveyance container, the bottom pad has a plate shape whose upper surface is lower than the protruding height of the convex portion and above the groove bottom position of the lateral support groove. It shall be. Thereby, the lower end part of the plate-like body fitted in the auxiliary groove and the supporting groove of the convex part can be supported by the bottom pad without being brought into contact with the groove bottom.

  In the transport container for the plate-like body according to each of the inventions, it is preferable that a top pad for protecting the upper end portion of the plate-like body is provided inside the lid body. In this case, it is preferable to provide an inner lid that holds the top pad inside the lid body and fits to the upper end of the side wall of the container body, and the top pad can be handled together with the inner lid. .

  In the transport container of the plate-like body, the inner lid has the upper end of the side wall on both sides of the lower surface of the top plate along the other opposing side walls that do not have the vertical supporting groove of the container body. An end wall that fits inside is suspended, and is open to the sides on both sides along the side walls having the supporting grooves in the vertical direction. Can be installed. As a result, the top pad mounted on the inner lid can be applied while confirming from the opening side, and the displacement caused by the inward bending deformation of the both side walls of the container body that does not have a support groove is described above. Can be suppressed.

  In the transport container of the plate-like body, a convex portion is provided on the lower surface of both side end portions on at least the opening side of the inner lid, and the inner lid and the end wall are the container body on the convex portion. A plurality of lateral support grooves are provided in parallel with the longitudinal support grooves of the container body in the state of being fitted into the upper end of the side wall of the container, and the support is provided in the recesses between the convex portions on both sides. A top pad that elastically abuts against the upper end of the plate-like body that is fitted and supported in the groove for use can be provided. As a result, since the supporting grooves on the convex portions at both side end portions are exposed to the sides, the inner lid is attached to the upper end portion of the plate-like body accommodated in parallel with the container body. It can be easily attached while checking and aligning the position of the plate-like body and the position of the supporting groove.

  In the plate-shaped transport container, the support grooves on the inner surfaces of both side walls of the container body, the support grooves on the bottom convex portion, and the support grooves on the convex portion of the inner lid are open on both sides. The taper may be continuous from one end to the bottom of the groove. In this case, since there is no refracting portion on the inner side surface of the support groove, even if the thin plate-like body supported by the end fitting into the support groove is bent and deformed locally, There is no strong contact and there is no risk of damage to the end.

  In the transport container of the plate-like body, at the upper end portion of each side wall of the container body, one of the inner and outer sides is cut out, and a fitting edge is formed on the other side of the inside and outside, and the lid body is formed on the protruding edge. On the other hand, it shall be provided so that it may fit in one side inside and outside. Thereby, deformation | transformation of the side wall upper end part of a container main body can be controlled with a cover body by fitting of a cover body, and overall shape retention property can be improved.

  In the transport container of the plate-like body, a reinforcing material having an upper plate portion covering at least the upper end surface of the protruding edge and having rigidity in the inside and outside of the container is provided at the protruding edge of the upper end portion of the side wall of the container body. It can be attached. Thereby, in the packaging state with the lid attached, when the upper end of each side wall of the container body is reinforced by the reinforcing material attached to the fitting edge, only when the synthetic resin foam is used. Compared to the shape retention, the side wall can be prevented from being bent or deformed outward or inward. Therefore, even when the support groove for supporting the upper end portion of the plate-like body is formed on either the top pad or the inner lid, the support groove is displaced with respect to the support groove on the inner surface of the side wall of the container body. It does not occur. Therefore, it is possible to prevent the accommodated plate-like body from being greatly bent or from being detached.

  In the plate-shaped transport container having the inner lid, the inner lid has shape retention and elasticity comparable to the container main body and the lid, or is more flexible than the lid. The top pad can be made of a synthetic resin foam having a shape retaining property and elasticity that are more flexible than the inner lid.

  As described above, according to the plate-shaped conveyance container of the present invention, when a plate-shaped body such as a glass substrate to be stored is stored in the container main body, the vertical support of the inner surfaces of the opposite side walls of the container main body is performed. By inserting and dropping the plate-like body into the groove, the lower end corner of the plate-like body can be fitted into the auxiliary groove on the bottom upper surface continuous with the vertical support groove, which serves as a guide Moreover, it can be securely fitted into the supporting groove set inward of the upper surface of the bottom without deviation. Therefore, even if the plate-like body is a fairly thin glass substrate used for a touch panel or the like, the storing operation can be easily performed and the protection can be satisfactorily achieved.

  The container body 1 is integrally formed of a synthetic resin foam having moderate rigidity and shape retention, and includes four side walls rising from the bottom 11, that is, front, rear, left and right side walls 12a, 12a, 12b, 12b. Of these, as shown in the example of the figure in the opposite side wall, for example, the left and right side ends of the plate-like body B to be stored are inserted and supported on the inner surfaces of the left and right side walls 12b and 12b on the short side. A plurality of supporting grooves made up of vertical grooves, that is, supporting grooves 13 in the vertical direction (vertical direction) are arranged in parallel at equal intervals. Usually, a support groove for supporting the lower end portion of the plate-like body B is set in parallel with the support groove 13 inward of the upper surface of the bottom portion 11 as described later.

  In the case of the illustrated embodiment, as shown in FIGS. 2 to 4, a lateral direction (horizontal direction) extending inwardly on the upper surface of the bottom portion 11 continuously from the lower ends of the support grooves 13 of the side walls 12 b and 12 b. ) Auxiliary grooves 13 a are formed, and the auxiliary grooves 13 a are provided so as to continuously support the lower end portion of the plate-like body B from the supporting grooves 13. Therefore, on the upper surface of the bottom portion 11, convex step portions 15a, 15a are provided at both end portions along the side walls 12b, 12b having the vertical support grooves 13, and the convex step portions 15a, An auxiliary groove 13a continuous from the support groove 13 is continuously formed in 15a. The auxiliary groove 13a has the same depth as that of the upper surface of the bottom portion 11, but may have the same depth as a support groove of an inward convex portion described later.

  Furthermore, the upper surface of the bottom portion 11 is the same as the convex step portion 15a with a required interval in the opposite direction of the side walls 12b and 12b inward from the convex step portions 15a and 15a at both ends. A convex portion 15b having a height is provided so as to define one or a plurality of concave portions 16, and each convex portion 15b has a plurality of supporting portions arranged in parallel with the supporting groove 13 and the auxiliary groove 13a, respectively.
