PURPOSE:To enhance the efficiency of the provision and the formation of a lid, which is provided with a concave part into which the parts of a handle are installed, by attaching a handle, which is prepared by fixing a handle grid to a pair of flexible handle arms, to the said lid. CONSTITUTION:A handle 8 is made of a synthetic resin such as polypropylene, and consists of a pair of flat handle arms 9, which have a flexibility and are integrated with the ends of a coupling piece 10, and a handle grid 13 provided with holes into which ends of the handle arms 9 are fitted. The handle 8 is attached to a lid 2 having a coupling-piece installing concave 4, which is formed adjacent to a lid side-wall 2 provided with penetration holes 3, handle-arm installing concaves 5 and a handle-grip installing concave 6. As a result, the cost of a metal lid-formation mold becomes relatively low, and the formation efficiency of the lid 2 can be enhanced. |
