Abstract

A container is thermoformed from a multilayer sheet, which includes a container body and a flange extending outward from a circumference of an opening of the container body. An end of the first layer extends over an edge of a peeled surface toward a bottom side on an outer end surface of the flange. When a lid is heat-sealed to the flange of the container, even if a seal resin is melted and flowed toward the end surface of the flange, since the edge of the peeled surface is covered with the end of the first layer, the seal resin will not adhere to the edge of the peeled surface.
