Abstract: The flexible container relating to the present invention comprises a cylindrical member (10) made from flexible film, a bottom plate member (12) which is harder than the flexible film, fitted into the inner side of a first end section of the cylindrical member (10) and fused-bonding airtightly; and a ring member (11) which is harder than the flexible film, fitted into the inner side of a second end section of said cylindrical member (10) and fused-bonding airtightly. According to this flexible container (2), it is possible greatly to reduce the volume of the container after discharging the highly viscous material from the flexible container, and it is possible to achieve small and inexpensive molds having excellent productivity as molding equipment for forming the bottom plate member (12) and the ring member (11), thereby achieving benefits in that the price of the equipment can be reduced significantly.

Abstract: A ring-like reinforcement part 2 is secured to an upper end face of a bottomed cylindrical container main body 1. The container main body 1 is formed of a flexible film-like member which is composed of polyethylene, polypropylene or the like. The reinforcement part 2 has strength enough to prevent the container main body 1 from greatly deformed and to prevent liquid, such as adhesive agent, coating material or the like stored in the container main body 1 from overflowing when the container main body 1 is lifted up through the reinforcement part 2.
