<P>PROBLEM TO BE SOLVED: To provide a high-quality flexible container for medical use that can be stably maintained in a state in which an aperture is widely opened when performing the task of injecting a liquid material and that hardly generates concentration of stress. <P>SOLUTION: A pair of opening/closing operation sections 40a, 40b are provided on the outer surface of a flexible bag member 20 by loosening the center section thereof in a manner so that insertion paths 45a, 45b into which a finger can be inserted are formed. At least one end 42a, 42b, 43a, or 43b on the upper side or lower side of at least one of a pair of opening/closing operation sections is fixed to the outer surface of the flexible bag member by means of heat sealing. The heated region 52a, 52b, 53a, 53b for fixing the at least one end by means of heat sealing includes all of the terminal end edge of at least one end. At the points of intersection between the outer peripheral edge of the heated region and the lateral end edges of the opening/closing operation section, the outer peripheral edge is oblique relative to the longitudinal direction of the opening/closing operation section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
