PROBLEM TO BE SOLVED: To make a mouth stopper inserted into a mouth part of a bag body formed of film welded, being flattened by deformation, to the aforementioned mouth part with the mouth part pressed from both sides by vertical welding members, and to make the mouth stopper restored approximately to its original shape with the pressing from both sides released. SOLUTION: The package is made up by inserting a mouth stopper 1 that is made up by forming a synthetic resin film 1a meltable relatively at low temperature over the surface of a tubular body made of synthetic resin meltable relatively at high temperature into a mouth part 2a of a bag body 2 whose inside is formed of film meltable relatively at low temperature, and by welding the mouth part 2a, with the mouth stopper 1 projecting toward the outside, and furthermore by welding a part separating toward one side at a specified distance from the mouth stopper 1 in the breadthwise direction to form a long bag body 2. Then, contents are filled to the long bag body 2 with a contents filling device, and after the filling the long bag body 2 is moved for a specified distance until finish of welding that is applied in the breadthwise direction to a part separating toward the other side at a specified distance from the mouth stopper 1 of the long bag body 2. |
