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.

Abstract: A method and apparatus for producing multilayer fibrous mats is provided which can form alternate short and long fiber layers continuously on a single forming endless wire cloth. The layers are brought together under the influence of suction air and are held together by interfiber bonds at their interfaces. The apparatus is composed of long fiber defibrators and a short fiber disperser unit placed above the forming endless wire cloth. First, a thin web of long fibers is formed on the forming wire cloth and then a short fiber mat is formed on top of the said long fiber web. At this point, the short fibers to a certain extent are pulled into and among the long fibers of the thin long fiber web by the use of suction air thus forming a long fiber layer, long-short fiber interface layer and a short fiber layer mat construction.
