Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
In a container having a lid and a pour opening in the lid for the discharge of the contents of the container, an articulated closure for the opening comprising a mounting element on the lid adjacent the inner end of the opening, a relatively rigid closure element hinged to the mounting element for overlying the opening to seal the contents within the container, a lift element integrally formed with the closure element on the end opposite the mounting element and liftable relative to the closure element to break the seal and lift the closure element away from the lid along the hinged connection between the mounting and closure elements, depending means integrally formed from the underside of the mounting element to mount the mounting element to the lid and interlocking with the lid to prevent rotational movement of the mounting element relative to the lid, an opening in the lid to accommodate the depending means and enlargement means integrally formed on the depending means beneath the opening in the lid to anchor the mounting element thereon.
