Abstract
A liquid container sealing construction comprises a container body having at least one open end surrounded by a marginal edge thereof and an end closure member closing the open end of the container body. The container body is coated on its inner surface with a heat sealable thermoplastic material. The end closure member includes a peripheral flange coated on its outer surface with a heat sealable thermoplastic material. The peripheral flange and the marginal edge jointly provide a contacting portion where they are intimately fused and united together by the heat sealable thermoplastic material, and also provide a portion where they are held out of contact with each other, the latter portion being located adjacent to the turned edge of the flange. There are also provided a method and apparatus for sealing the liquid container with the end closure member.
