Description

Plate-shaped container for transport Field of invention

The present invention relates to a container for transporting a plate-like body of various glass substrates, panels, and the like, or other plate-like bodies, such as a transfer, a tube sheet glass, a liquid crystal display, or a plasma display glass substrate.

Background of the invention

In the past, a container for transporting a large glass substrate such as a plain glass or a glass substrate for liquid crystal display or other non-impact plate-like body is generally used as a cushioning synthetic resin foaming system. The container having the container body and the lid body is inserted into one of the vertical grooves which are arranged at equal intervals on the inner surface of the side wall of the container body, and is supported in an upright state without being in contact with each other.

In recent years, the demand for large-size LCD TVs and plasma TVs has increased, and glass substrates for televisions have also used large-sized glass substrates with one or both of them in the vertical and horizontal directions. Therefore, the transport containers for transporting the substrates are also large. Chemical.

In the method of accommodating the glass substrate in an upright state in the longitudinal groove on the inner side surface of the conventional side wall, the glass substrate which is increased in weight due to the large size, the glass substrate is bent and deformed by its own weight, or the weight of the glass substrate is concentrated on the container body. The load, while the bottom of the container is compressed and deformed, the buffer function or the impact mitigation function is impaired.

In order to avoid this problem, as exemplified in Patent Document 1, the glass substrate and the protective sheet are alternately stacked and stored in the container body, and the protective container is used to receive the glass substrate.

In general, in order to improve the efficiency of the conveyance, as described above, a plurality of containers in which the plate-shaped body is accommodated are bundled in a stacked state for transportation. In the case of laminating, it is required that each container can be held with good stability without occurrence of offset. Therefore, in Patent Document 1, the upper surface of the lid body of the lamination surface as the lamination is placed below the bottom of the container body. One of the concave portions (grooves) is formed, and the other is formed with a convex portion (a ridge), and the concave portion and the convex portion are laminated in a fitted state.

In the case of the fitting structure of the concave portion and the convex portion, when the fitting structure is located on the inner surface of the lid body as the lamination surface and the inner side of the bottom surface of the container body, and the air in the concave portion is not easily discharged, the lamination operation is performed. In addition, it is not easy to fit, and when the containers stacked in the fitted state are separated into containers one by one, the lid of the lower container is attached to the bottom of the upper container and then falls off.

Further, when the concave portion and the convex portion of the fitting structure are formed on the inner side of the lamination surface and are not visible from the outside, it is difficult to confirm whether the upper container is stacked at the correct position from the outside of the laminated state during lamination, and the foregoing Whether the concave portion and the convex portion are normally fitted. When the positional displacement occurs during lamination, the laminated state is unstable, and there is a collapse in the conveyance, and the positional displacement is liable to cause deformation such as depressions in the fitting portion between the concave portion and the convex portion, and thus it is impossible to obtain Prevent the effect of offset.

Therefore, in the case of the above-described lamination, it is desirable to re-stack the container in a normal position when the positional displacement occurs in the container, and the above-described laminated state can be easily confirmed. However, Patent Document 1 does not consider such a consideration.

Further, when the container is stacked for transport, when the load of the upper container due to the lamination, that is, the stacking load is applied to the top plate portion of the lid of the lower container, the stored plate-shaped body receives the laminated load, and There is a flaw in the breakage or breakage of the plate body.
