A removable internal support for a flexible bag made of flexible material with material memory so that the removable internal support for a flexible bag will attempt to return to a flat configuration when rolled up: Locking apertures constrain the removable internal support for a flexible bag in a rolled-up configuration for insertion into a flexible bag. Rounded corners defined by the intersection of a bottom edge and a top edge with vertical edges, and rounded intersection corners at the intersections of the locking apertures with the vertical edges, prevent the removable internal support for a flexible bag from snagging a flexible bag in which it is installed. The locking apertures are quickly and easily released once the removable internal support for a flexible bag is in position in the flexible bag. After being unlocked from its rolled-up configuration, the material memory inherent in the removable internal support for a flexible bag attempts to return the removable internal support for a flexible bag toward a flat configuration, but is constrained in an approximately cylindrical shape by the flexible bag in which it is installed. The flexible bag may then be filled, and the removable internal support for a flexible bag subsequently removed by simply pulling it out of the bag. The flexible bag may then be tied shut and disposed of in the conventional fashions, and the removable internal support for a flexible bag is ready for re-use.
