<p>PURPOSE:To permit an easy opening and complete sealing of a container, by providing an intermediate film attached to the inner surface of the container body and a flange, a lid film heat-sealed to the intermediate film and a cut-out for opening formed in the intermediate film inward of the heat sealed part. CONSTITUTION:A flange 2 is formed at the edge of an opening at the top of a container body 1 made of synthetic resin. An intermediate film 3 is attached to the upper surface of the flange 2 and has a thinner wall than the synthetic resin film forming the container body 1. The adhesive strength of the aforesaid film-to-flange attachment made with an adhesive agent is weaker than by fusion sealing. A gripping part 5 having a cut out groove 4 is formed at one corner of the flange 2. A lid film 7 is heat sealed to the intermediate film 3 by the application of ultrasonic waves, heat, etc., after the container body 1 receives its content 6 such as TOFU therein. To open the container, the lid film 7 is pulled up with the gripping part 5 held between the fingers to tear off the lid film 7 and the intermediate film 3 together integrally from the container.</p> |
