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.

1-11. (canceled)
A container that is molded from a multilayer sheet having a peeled surface on an inner layer, comprising:
- an opening from which a content is filled;
- and
- a flange extending outward from a circumference of the opening, wherein
- on an outer end surface of the flange, an end of an innermost layer disposed on an inner side of the container including an upper surface of the flange extends over an edge of the peeled surface formed on the flange toward a bottom side of the container.
A packaging body comprising:
- a container that is molded from a multilayer sheet having a peeled surface on an inner layer, the container including an opening from which a content is filled and a flange extending outward from a circumference of the opening;
- and
- a lid that is welded to the flange of the container, wherein
- on an outer end surface of the flange, an end of an innermost layer disposed on an inner side of the container including an upper surface of the flange extends over an edge of the peeled surface formed on the flange toward a bottom side of the container.
A manufacturing method of a container that is molded from a multilayer sheet having a peeled surface on an inner layer and includes:
- a container body having an opening from which a content is filled;
- and a flange extending outward from a circumference of the opening of the container body with the peeled surface being formed, the method comprising:
- forming the container body from the multilayer sheet;
- and
- setting a cutting die on a surface opposite to an innermost layer located on an inner side of the container body to die-cut the multilayer sheet at an outer circumference of a part corresponding to the flange.
