Abstract

Process for the manufacture of a flexible bag adapted to contain a liquid and which is provided with a check valve at one end, characterized in that two portions of sheet thermoplastic material, which constitute the body of the bag, are placed in face contact face with two portions of the thermoplastic material constituting the valve and extending between one end of the portions of the body towards the other end, said valve and the portions of the body leaving each other to close the bag by common closing between the valve, and portions of the body, and said common sealing between the valve portions being interrupted to provide an entry opening at one end of the bag.
