A package for preserving fresh fruits, meats, flowers and the like by vacuum packing same in a tubular shaped cylindrical type container. The container is covered with a thermo, transparent, resilient, plastic material and sealed after the air is withdrawn. There is a signaling means for indicating whether the vacuum has been breached and air has entered into the chamber comprising of a green disc that falls away from a red spot whereby the red spot appears through an opening in the end plate. There are end plates independent of the cylindrical chamber and secured to same for convenience in storage and safety in transit. The end plates have a flat surface of sufficient area so as to act as support members and are secured at each end of the cylindrical container so as to form a unitary package.
