<P>PROBLEM TO BE SOLVED: To provide a storage body with a spout, easily manufacturable with a simple structure, and capable of surely preventing outside air from flowing in a storage part when injecting a storage object. <P>SOLUTION: This spout 10 of the storage body 1 with the spout has a body part 11 integrally formed with a first welding part 12 to which sheet-like members 2a and 2b for constituting a storage body 2 are welded and a cylindrical flow passage cylinder part 15 projecting in a cylindrical shape to the sheet-like members welded to the first welding part 12. An outer peripheral surface of the flow passage cylinder part 15 is covered with a bag-shaped member 20, and the opening area of the bag-shaped member is welded to it. The outer peripheral surface has a second welding part 15c to which the opening area is welded so as to have a clearance G between the outer peripheral surface of the flow passage cylinder part 15 and welding edge part of the bag-shaped member. A cavity part R and a close contact part R1 are formed in the bag-shaped member 20 by welding the bag-shaped member 20 to the second welding part 15c, and the storage object can be injected via the cavity part R and the close contact part R1 by cutting a tip part of the bag-shaped member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
