<p>PURPOSE: To obtain a seal lid for a cup containing precoocked food, by which the cup can be closed tight by detachably sealing the lid and hot-water poured in the cup can be easily drained. CONSTITUTION: A sealing lid S consists of a lid main body 1 that is made of a sandwich laminate of a water- and oil proof paper 11, a polyester film 13 and a polyethylene layer 12, and a polyethylene film 2 with through-holes 20 at an end. An adhesive 3 is applied on the polyethylene layer 12 in a lattice pattern and the polyester film 13 is partly bonded on it, so that they are peelably formed into one piece of the sealing lid S by weak bonding. A protruding finger knob 10 is provided at one end of the lid main body 1 and a protruding finger knob is provided on the sealing lid S on the opposite side of the finger knob 10. To detachably mount the sealing lid S on a cc>ntainer, the polyethylene film 2 on the back of the sealing lid S is lightly heat-sealed to the rim of the container. When the lid main body 1 is peeled off a little from the polyethylene film 2, line film 2 remains bonded to the rim and the through- holes 20 are exposed, so that hot-water can be drained.</p> |
