The tab seat is disposed in spaced relation to said upper surface of the bottom and disposed in such a manner that a score portion having as small a width as possible is formed between the outer periphery of the tab seat and the inner peripheral edge of said reinforcing thermoplastic resin layer. The upper surface of said bottom is exposed through the score portion.
