Abstract
A beverage container lid (1) includes a lid body (10) and a pull cap (20) that are both made of thermoplastic resin. The lid body is provided with an opening (11) for discharging contents from the container when the lid is mounted on a beverage container (40). The pull cap (20) includes a cap portion (21) and a pull tab portion (22) that are connected to one another. The lid body is made from a laminate that includes an easy-peel layer and a gas-barrier layer. The easy-peel layer forms an outermost layer of the lid body. The opening (11) in the lid body (10) is covered with a gas-barrier film (15) and the film is bonded to the peripheral portion (14) of the lid body surrounding the opening (11). The lower surface of the peripheral portion (23) of the cap portion (21) is removably attached to the upper surface (13) of the lid body (10) through the gas-barrier layer (15).
