Abstract
It is a method for producing a food-filled and sealed container having a high product value, in which a container lid made of resin is not deformed after sealing. In this method for producing a food-filled and sealed container, after a food is filled in a container body (10) made of thermoplastic resin, the container is sealed by heat sealing a container lid (20) made of thermoplastic resin, and the container body (10) and/or the container lid (20) have sealing surfaces (13, 24) provided with a concavity or convexity.
