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 into 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.
Support interne amovible pour sac flexible fait d'un matériau flexible avec mémoire permettant au support interne amovible pour sac flexible de retourner à sa configuration aplatie lorsque mis en forme. Des ouvertures de blocage maintiennent le support interne amovible pour sac flexible dans sa configuration cylindrique pour insertion dans un sac flexible. Les coins arrondis définis par l'intersection des bords inférieur et supérieur avec les bords latéraux, et les coins arrondis des ouvertures de blocage en intersection avec les bords verticaux empêchent le support d'accrocher le sac flexible dans lequel il est inséré. Les ouvertures de blocage sont rapidement et facilement désengagées une fois que le support interne amovible pour sac flexible est en position dans le sac flexible. Dès que libéré des contraintes de configuration cylindrique, le matériau à mémoire du support interne amovible pour sac flexible tend à ramener le support à sa configuration aplatie, mais celui-ci il est maintenu dans un forme approximativement cylindrique par le sac dans lequel il se trouve inséré. Le sac flexible peut alors être rempli. Après remplissage du sac flexible, il suffit de retirer le support amovible du sac flexible qui peut alors être refermé, tandis que le support interne amovible pour sac flexible est prêt pour réutilisation.
