发明名称 PLATE-LIKE MEMBER STORING CONTAINER, STRUCTURE OF INNER CASE THEREOF, AND METAL MOLD FOR INJECTION MOLDING FOR THE INNER CASE
摘要 <p>PROBLEM TO BE SOLVED: To provide a structure of an inner case of a plate-like member storing container, for which a molding material flows well and moldability is good at the time of injection molding. SOLUTION: This inner case 20 of a plate-like member storing container has a structure that the inner case 20 is stored in the plate-like member storing container in which a portion between an outer case main body and an upper lid covering an upper part of the outer case main body to be joined thereto is pressed by a locking means to keep the container in an airtight state, and that the inner case 20 is formed by injection molding to store a plurality of plate-like members in good order. An upper part of the inner case 20 having a rectangular shape in a plane view is opened, and a plurality of longitudinally long grooves are formed at equal pitches inside a pair of side walls 20a, 20a opposed to each other, respectively. Legs 20c are formed which enable lower ends of the side walls 20a, 20a to be placed on a bottom face of the outer case main body, and a recess 26 is provided in a bottom face 24 of each of the legs 20c. Gate positions for injection molding are set at the recesses 26 and, as a result, gate marks 25 are formed at the recesses 26.</p>
