PROBLEM TO BE SOLVED: To provide a mechanism of a simple configuration which can fixes and holds easily even a relatively thick bag body difficult to deform in a drawn form, in a state where the upper end part of an opening is spread, and allows easy fixation and de-fixation operations.SOLUTION: A storage case stores a bag body 31 inside it in a state where the upper end part of the bag body is unsealed and has a bottomed cylindrical case body and a synthetic resin-made mouth frame body 11 engaged with and fixed removably to the upper end part of the case body. The mouth frame body has a suspension cylindrical piece 16 suspended into the case body and forms a clearance between the peripheral wall of the suspension cylindrical piece and the side peripheral wall of the case body. A part of the peripheral wall of the suspension piece constitutes a pressing piece 21 configured so as to be displaceable in a reversed state between inner- and outer-side positions of the peripheral wall, and the unsealed upper end part of the bag body 31 is pressed toward the side peripheral wall of the case body 1 by the pressing piece at an outer-side position of the pressing piece to fix and hold the bag body with the unsealed upper end part of the bag body spread in an annular state. |
