PURPOSE: To provide a container which is capable of being used for a long time after it is unsealed.
CONSTITUTION: A container comprises at least one medium layer, an inner coating 8 and an outer coating 4. A first opening part is formed in at least one medium layer, and at least the inner coating 8 and the outer coating 4 are joined with each other to form a film laminate layer in the first opening part. A potential opening part is formed in the first opening part. The potential opening part can be unsealed by breaking the film laminate layer along a weakened line 41. At least the outer coating 4 and the inner coating 8 of the film laminate layer are adhered to each other, and since the potential opening part is smaller than the first opening part, and an inner circumferential edge of the first opening part is kept sealed by at least one coating in unsealing the potential opening part. Thus, no content infiltrates a thick paper 5.
