Abstract: The present disclosure relates to a closure system for a flexible container. The closure system generally includes a flexible member and a substantially rigid member. The flexible and rigid members are each interconnected to opposing portions of an aperture of the container. When the closure system is in a closed state, the flexible member is in a position proximate to the rigid member. The flexible member may be pulled away from the rigid member to move the closure system to an open state. The closure system will remain in the open or closed state without contact from the user. The user may return the closure system to the closed state by applying a predetermined force to the flexible member.
