Abstract
Procedure of extraction of air and closure in containers for food preservation characterized in that the extraction of air and closure by vacuum is obtained by raising the temperature of the preserved food or stew contained in the container body until a slight vaporization is produced at which time apply the cover that fits the body by means of a washer or elastic joint allowing it to cool until the condensation of the vapors produces sufficient vacuum so that the lid is applied to the body by atmospheric pressure, leaving the container permanently closed. Air inside and able to keep content indefinitely. (Machine-translation by Google Translate, not legally binding)
