发明名称 VAC SAC
摘要 The present methods for storing food at home consist of various types of plastic bags or Tupperware which seal air out but they also seal air in. This invention answers the question of how to eliminate most of the air from the food by producing a plastic bag with a beach ball type of valve which enables the user to suck out the air using the lips and then using a stopper to keep the air out.
