Abstract:

This oxygen absorption vessel (1) has: a vessel main body (10) having multi-layer structure comprising an innermost layer (30), and outermost layer (31), and an intermediate layer (32) therebetween, and having an opening section (20) at the top; and a sealing member (11) that is adhered to the top end surface (21) of the opening section (20) of the vessel main body (10), sealing the opening of the opening section (20). The innermost layer (30) and intermediate layer (32) curve outwards at the top end of the opening section (20), forming a flat section (A), and the surface of the flat section (A) forms the top end surface (21) of the opening section (20). When the sealing member (11) is unsealed, a portion of the innermost layer (30) at the top end surface of the opening section delaminates, and so evidence of unsealing remains
