<p>PROBLEM TO BE SOLVED: To desirably maintain the sanitary state in a distribution stage and to reduce the deterioration of contents or the like by making an unsealed pour port reclosable. SOLUTION: A ridgelike joining part 9 of flap pieces 7, 8 for closing a pour port 3 of a pack container body 2 is sealed with a sealing member 4. In the member 4, an adhesive paste layer 11 is formed on one side of a sheet-like base material 10, and by folding the material 10 in two with the layer 11 being directed inward, the whole joining part 9 of the container body 2 is wrapped in the material 10 in a sealed state. A first sealing piece 13 and a second sealing piece 14 differing in shape from each other in the sealed state are peeled off from each other along a peeling guide 15.</p> |
