To allow at least a start end and a final end of adhesion of an adhesive tape to have sufficient adhesive force in a peeling direction while an intermediate adhesive part is relatively easy to be peeled off in a direction for unsealing the adhesive tape.

An uneven face having a sufficient width for pasting a commercially available adhesive tape for packing from a fitting rim 4 is formed on both outer sides 2a, 3a of a container body 2 and a lid 3. The uneven face comprises a longitudinal arrayed face 5 including a plurality of protruding lines 5a having an appropriate length elongated in an orthogonal direction to the fitting rim 4 and a lateral arrayed face 6 including a plurality of protruding lines 6a having an appropriate length elongated in a parallel direction to the fitting rim intermittently formed with appropriate lengths. The longitudinal arrayed face 5 is formed in a range where a start end and a final end of an adhesive tape can be pasted at the center of at least a side, preferably on both opposite sides, while the lateral arrayed face 6 is formed on other faces.
