Method for manufacturing a can-like container

A method for forming a can-like container comprising the steps of:

• providing a blank sheet, said blank sheet comprising a metal foil layer having a thickness of no more than 40 .mu.m, and a hot-melt resin layer formed on at least one side of said metal foil layer;
• cutting said sheet to provide a blank having dimensions established in accordance with desired dimensions of said containers;
• placing said blank over one side of a female mold, said female mold having a hollow central portion having dimensions established in accordance with said desired dimensions of said container, said female mold having grooves in its side wall portions;
• pressing a male mold against said blank and into said hollow portion of said female mold to thereby provide a container having wrinkles in side wall portions corresponding to side wall portions of said female mold, said female mold having four substantially straight sides and four corner portions for gathering said wrinkles at said four corner portions;
• providing a tray around said container body, said step of providing said tray comprising injection molding a resin material around a portion of said container body;
• and attaching a cover to said container body opposite the portion thereof surrounded by said tray, said cover comprising a metal foil layer having a hot-melt resin layer on at least one side thereof.
