The body of the container is fabricated with a multi-layer sheet composed of a metal foil layer having a thickness of no more than 40 .mu.m and a hot-melt resin layer formed on one or both sides of the metal foil layer. The margin portions of the multi-layer material of the container body in corners thereof are either folded into two tucks at each corner or formed into vertical wrinkles upon molding the container body. A cover is joined to the container body, which cover is also composed of a metal foil layer and at least hot-melt resin layer.
