Container for conveying substrate, inner wall structure of the container, and bottom raising member used for the container

Abstract

A container for conveying a substrate, the main part of which container is made from a foamed synthetic resin. In the container, loading and unloading of a glass substrate into and out of a container body is facilitated and unexpected vertical movement of the substrate during conveyance is prevented, thereby the substrate is less likely to chip or crack. [MEANS FOR SOLVING PROBLEMS] A container body of a container for conveying a substrate is constructed from foamed synthetic resin inner heat insulators and sheet members so as to form double walls of the heat insulators, and the heat insulators and members are formed as separate bodies in advance. Vertically arranged inner heat insulators are provided with inclination where the thickness of the heat insulators gradually thins from the opening of the container body downward. Further, in an inner heat insulator provided on the bottom side of the container body, a recess is formed in the thickness direction, and a slit in which a drying agent can be inserted is formed in a sheet member placed on the recess.

Description

technical field [0001] The present invention relates to a substrate conveyance container suitable for accommodating and conveying a plurality of approximately rectangular glass substrates for liquid crystals, etc., an inner wall structure of the conveyance container, and a bottom lifting member suitably used in the conveyance container. Background technique [0002] Usually, when moving substrates such as glass substrates for liquid crystals to other places during the manufacturing process, etc., a container for substrate transportation is used in a state where a plurality of sheets are tightly closed and a lid is fitted so that the substrates do not come into contact with each other and contamination is prevented. And it can be transported safely without cracking or chipping on the substrate. [0003] Among such substrate transfer containers, there is a substrate transfer container in which both a substantially rectangular parallelepiped container body and a lid attached to...

Problems solved by technology

Therefore, if rubbing or the like occurs on the glass substrate during transportation, there is a problem in particular that the support groove part of the inner surface of the container body that is in direct contact with the glass substrate is prone to deterioration. As a result, the substrate support groove made of foamed synthetic resin Chipped off, the foam adheres to the glass substrate as dirt

Therefore, sometimes a desiccant is stored in the container main body or the lid body. Since such a desiccant is generally bonded by tape or the like, if the adhesive force of the tape decreases and the desiccant falls, the surface of the glass substrate that exists is covered with the desiccant. damage problem
