PROBLEM TO BE SOLVED: To prevent any damage at a contact part between an inlet of a bag stored in a casing and the casing. SOLUTION: A casing 3 comprises a top plate 31, a side surface part 32, and a bottom surface part 33. The top plate 31 has a top plate recessed part 34 which is recessed from a surface part of the top plate 31, an opening part 35 formed in a bottom surface of the top plate recessed part 34, and an abutting part 36 which is provided around the opening part 35 with a cap 4 being abutted thereon. A bag body 2 has an inlet 22, and the inlet 22 is projected outward of the casing 3 from the opening part 35. The cap 4 comprises an upper surface part 41, a side surface part 42 and a flange 43 provided on a peripheral edge of the side surface part 42. The outer peripheral diameter of the flange 43 is larger than the diameter of the opening part 35. When the cap 4 is fitted to the inlet 22, the abutting part 36 is held by the flange 43 and an inlet peripheral part 24 to fix the casing 3 to the bag body 2. COPYRIGHT: (C)2009,JPO&INPIT
