摘要： Method for the simultaneous extrusion and filling of expandable thermoplastic containers wherein the expandable thermoplastic material is extruded, clamping means gather and seal the foamed thermoplastic after it is extruded and while it is still in a state of plasticity so that the sealed area is formed by fusion of a foamed thermoplastic material, intermittently operated feed means fills the container after the seal is made and the substance being packaged causes inflation and shaping of the container, and clamp means is operative upon the deenergization of the feed means to effect a similar type seal for the other end of the container.
