摘要

A task of the present invention is to provide a container sealing structure capable of easily and surely unsealing a container and hygienically maintaining an opening portion at the time of resealing, and a method of manufacturing the sealing structure. The container sealing structure of the present invention is configured by integrally forming a pouring portion ( 12 ) and a cap portion ( 16 ). An easily breakable portion ( 15 ) is formed in the container sealing structure. The pouring portion ( 12 ) and the cap portion ( 16 ) includes an intermediate wall ( 13 ) which is formed by bending downwardly from an upper end portion of an inner wall ( 11 ) and an outer wall ( 14 ) which is formed by bending upwardly from a lower end portion of the intermediate wall ( 13 ).
