FLEXIBLE COLLAPSIBLE CONTAINER AND METHOD OF MOLDING |
摘要 |
<p>The method of molding flexible, collapsible containers comprises extruding a tubular parison of material to be molded and sealing the outer, free end of the parison, ballooning the parison with relatively low pneumatic pressure; closing the mold about the ballooned parison to cause the edges of the parison to protrude out of the mold chamber; and sealing said parison to form said container, including the step of forming seal lines positioned laterally inwardly from the lateral edges of the parison. A novel container design is also covered.</p> |
