For this reason, recently, a cool box using a decorative sheet such as a woven cloth or a leather sheet on the outer surface has been used.

[0003] These cool containers are mainly provided with a cool cover having a skirt formed on a peripheral edge. The cover is formed in a bag shape with a decorative sheet on the front and back, and has a soft inside. A heat insulating material having properties is included. Therefore,
When a skirt is formed on the cold insulation lid, the corners of the decorative sheet are pinched and closed, so that the decorative sheet may be creased or sewn on the corners, etc. Absent. Moreover, the sewing work for forming these skirts is troublesome.
In addition, if the heat-insulating material having flexibility placed in the bag-shaped lid is continuously inserted into the bag of the skirt portion, the skirt portion may be moved sideways due to the elasticity of the heat-insulating material placed in the skirt portion. Because the skirt shape could not be maintained due to the opening, the skirt portion was filled with heat insulating material separate from the top plate. However, when a heat insulating material separate from the top plate portion is put in the skirt portion, there is a disadvantage that the heat insulating effect is lost at a boundary portion between the skirt portion and the top plate portion.

[0004]

SUMMARY OF THE INVENTION The problem to be solved is that, in the lid used for the above-mentioned cold storage container and having a skirt, a fold of a decorative sheet formed at a corner or the like of the lid or the like. The sewing traces are not preferable in appearance, the sewing work for forming the skirt is troublesome, and if the skirt is provided with a heat insulating material separate from the top plate, the skirt and top plate The heat insulation effect is lost at the boundary.

That is, an object of the present invention is to provide a container lid which is good in appearance, is easy to manufacture, and hardly leaks cool air when used in a cold storage container or the like, and a method of manufacturing the same.

[0006]
