Abstract: For a sturdy, reusable insulated cold beverage container, a closure including a lid and a stopper. The lid has two holes through it--a large drinking hole preferably with an ice guard secured in it and a smaller straw hole for receiving a drinking straw therein. The stopper has first and second end portions and a hinge formed between them and is formed as a separate piece from the lid. The first and second portions can be snap secured to the lid and over the drinking and straw holes, respectively, to individually seal the holes and thereby prevent the liquid contents of the container from spilling out the holes. The snap securing structures advantageously provide the only attachments of the stopper to the lid.

Abstract: A closure cover for sealing a liquid container including a body having an orifice for dispensing the liquid in the container, and a rotating disk pivotally attached to the body and providing an effective seal for the dispensing orifice. The effective seal is created by a downward force upon a sealing gasket, such force being the result of the rotation of the disk member containing a ramp which is moved under a cam on the body.
