Abstract
A drop lid-shaped formed lid to be fittably applied to a container having a flange section is formed with a flange, a fitting section extending downwardly from the flange, and an introducing section below the fitting section. The introducing section is composed of first and second tapered sections whose inner diameters each decrease downwardly. The taper angle β of the second tapered section is larger than the taper angle α of the first tapered section, and the second tapered section is formed in an arcuate shape smaller than a range in which the first tapered section is formed.
