Blockage structure of pressure-resistant container, formation method thereof, gas generator using blockage structure of pressure-resistant container and manufacturing method thereof

摘要

The present invention is a blockage structure of a pressure-resistant container in which an opening of a metal normal container is closed by a metal blocking member, wherein the blocking member has a blocking portion, and the blocking portion has a thickness direction between the first surface and the first surface. It has a 2nd surface on the opposite side, and the circumferential surface part between a 1st surface and a 2nd surface, is the same shape as the said opening part, and is the size which can be inserted in the said opening part, The said closed structure is the opening part of the said normal container. In the inside of the closing member, the closing member inserted such that the second surface faces the inside of the normal container, and the peripheral wall portion on the opening side of the normal container are connected to the boundary between the first surface and the peripheral surface of the closing member of the closing member. The annular deformation part deformed to abut the 1st annular corner part which exists, and the contact part of the 1st annular corner part of the said obstruction part of the said closure member, and the said annular deformation part has a welding part welded from the outer side, It provides a closed structure of the pressure vessel.
