A package in which an opening piece made of a resin film that is shorter than the entire length of the package is welded to the outer surface of a packaging film that seals the contents, and that the packaging film and the opening piece are welded together. The pieces are welded and joined by a welded part occupying an area smaller than the area of the opening piece, and the welded part includes a curved line that is within the opening piece and surrounds a predetermined area with a knob margin left at the end of the opening piece. A welded structure of an opening piece in a package characterized by: 2. A package in which an opening piece made of a resin film that is shorter than the entire length of the package is welded to the outer surface of a packaging film that seals the contents, and the area of the packaging film and opening piece is smaller than the area of the opening piece. The welding part is welded and joined by a welding part that occupies a smaller area than the main welding line, and the welding part is characterized by consisting of a main welding line and a sub-welding line located closer to the edge of the opening piece than the main welding line. The welded structure of the opening piece in the package. 3. The welded structure of the opening piece in a package according to claim 2, wherein the welding strength between the opening piece and the packaging film by the secondary welding line is weaker than the welding strength by the main welding line. 4 A package in which an opening piece made of a resin film that is shorter than the entire length of the package is welded to the outer surface of a packaging film that seals the contents, and the packaging film and the opening piece are in contact with each other. It is welded and joined by a welded part that occupies a smaller area than the
A welded structure for a tear-opening piece in a package, wherein the welding part is made up of one or more welding lines, and an end portion of at least one welding line extends to an edge in the longitudinal direction of the tear-opening piece. 5. Claim 4, wherein the end portion of at least one weld line separates from the opening piece and extends to the packaging film.
The welded structure of the opening piece in the described package. 6. The welding part consists of a main welding line and a sub-welding line whose end part extends to the longitudinal edge of the opening piece,
6. The welded structure of the opening piece in a package according to claim 4, wherein the welding strength between the opening piece and the packaging film through the secondary welding line is weaker than the welding strength between the opening piece and the packaging film through the main welding line. 7. The opening piece and the packaging film are held between a protrusion formed on the anvil and a horn, and by applying ultrasonic waves from the horn side, a welded portion corresponding to the shape of the protrusion is formed, The protrusion that forms the sub-weld line is formed lower than the protrusion that forms the main weld line, and due to the difference in height of this protrusion, the weld bond strength of the sub-weld line becomes the weld bond strength of the main weld line. The welded structure of the opening piece in the package according to claim 3 or 6, wherein the welded structure is weaker than that of the opening piece.
