ABSTRACT:
A container lid structure made essentially of plastics. The lid structure includes a lid frame and a lid plate. The lid plate includes an inner layer comprising a metal foil coated at the opposite sides by plastic layers and connected at the peripheral portion with the lid frame and a core made of a material which is not adhesive to or has a weak bonding power with the plastic material for the lid frame and for the plastic layer of the inner layer. The core is laid over the inner layer with the peripheral portion in an abutting relationship with the inner periphery of the lid frame. A holding member is formed on the core and bonded to the inner layer through apertures in the core. A pulling tab is also formed on the core and bonded to the inner layer through an aperture in the core.
