Abstract
A receptacle for a beverage includes a cylindrical main body (10)having an open upper end (11) that is closed by a plastic lid (20). The plastic lid (20) is provided with an opening (23) for use in drinking or otherwise discharging the contents of the container. The opening (23) can be covered with a pull tab (30) or can be left uncovered. The lid (20) is provided with a flange (21) at a portion surrounding the outer periphery of the lid (20), and a cover film (50) is sealed to the flange (21) to cover the lid (20). The upper surface of the lid (20) is shielded from outside air by the cover film (50) and therefore can be maintained in a clean condition until the opening (23) is exposed for discharging the contents in the receptacle. Thus, dust, moisture and other contaminants are prevented from becoming deposited on the lid (20).
