<p>The present invention involves: attaching a lid body (3) to a flange section (25) in which the skirt section (26) of a container body (2) is provided, via a ring-shaped first heat-sealing part (23); attaching the lid body (3) to at least part of the outer-peripheral edge of a flat end section (27) extending from the skirt section (26), via a second heat-sealing part (29); starting interlayer detachment from the flat end section (27), as a result of unsealing from an unsealing start section (3A) constituting part of the lid body (3) and corresponding to the flat end section (27); and unsealing as a result of interlayer detachment from the second heat-sealing part (29) along the first heat-sealing part (23) up to the notch (28). The skirt section (26) is provided for the purposes of appearance, strength, user-friendliness, and the like; however, interlayer detachment is possible even in a configuration provided with one notch (28). Precision on the outer-peripheral side of the first heat-sealing part (23) is unnecessary, and it is easy to attach the lid body (3).</p> |
