STRUCTURE FOR FASTENING TOGETHER RESIN MEMBERS IN SUBSTRATE STORING CONTAINER

摘要

The upper wall is provided with a recess indented from the outside toward the inside of the container main body, and a protrusion projecting outward on the inside of the recess. The top flange is provided with an insertion part which can be inserted into the recess from the outside of the upper wall. The insertion part is provided with a through-hole capable of penetrating from the side further from the upper wall to the side nearer the upper wall. With the recess in the upper wall opening upward and the insertion part of the top flange inserted into the recess, a molten resin poured into the through-hole of the insertion part from above fills the recess from the bottom surface thereof up to the outer peripheral surface of the protrusion and the inner peripheral surface of the through-hole.

主权项

1. A structure for fastening together resin members in a substrate storing container that fastens a first resin member and a second resin member,
the first resin member constituting a substrate storing container that includes: a container main body having a substrate storing space that can store a plurality of substrates formed inside thereof, and having an opening circumferential portion at which a container main body opening portion that is in communication with the substrate storing space is formed at one end portion thereof; a lid body that is removably attached to the opening circumferential portion and can close the container main body opening portion; a lid body side substrate support portion which is a portion of the lid body and arranged at an inner side of the lid body corresponding to a side opposing the substrate storing space when the container main body opening portion is closed by the lid body, and can support edge portions of the plurality of substrates when the container main body opening portion is closed by the lid body; and a back side substrate support portion that is arranged so as to form a pair with the lid body side substrate support portion inside the substrate storing space, that can support the edge portions of the plurality of substrates, and that supports the plurality of substrates in cooperation with the lid body side substrate support portion when the container main body opening portion is closed by the lid body, and the second resin member constituting the substrate storing container, wherein the first resin member includes a recess that is indented from an outer side to an inner side of the substrate storing container, and a protrusion that protrudes outward at an inner side of the recess; wherein the second resin member includes an insertion part that can be inserted to the recess from outwards of the first resin member, and the insertion part includes a through-hole that penetrates from a side far from the first resin member to a side near to the first resin member; and wherein, in a state in which the recess of the first resin member opens upwards and the insertion part of the second resin member is inserted into the recess, molten resin that is poured into the through-hole of the insertion part from above is filled from a bottom face of the recess up to an outer peripheral face of the protrusion and an inner peripheral face of the through-hole.
