Abstract: A thermally insulated cup is formed from a single-walled paper or plastic inner cup and an insulating outer wrapper. The insulating outer wrapper comprises a paper base sheet or outer sidewall blank, optionally printed on one side, and a corrugated paper or foamed plastic insulating insert. The insulating insert is similar in shape to the outer sidewall blank but smaller in size. The insert is glued in a centered position to the non-printed side of the sidewall blank to form a two-layered insulating wrapper. Less than 20% of the area of the insert is glued to the base sheet. Specifically, no glue is applied to the area adjacent to the cut side edges of the insert, and as such these edges are not attached to the base sheet. The wrapper is then wrapped around the single walled inner cup. The side edges of the base sheet of the wrapper overlap and are sealed directly together to form a side seam. The side seam is itself adhesively secured to the side wall of the inner cup.

Abstract: A lid with a raised drink-through spout (24) has a hinged flap valve (28) covering a drink opening (26?) formed in the surface of the spout. The user opens the valve by pushing the top of a post (28P) on the flap (28F) down. A hinge (28H) holding the flap urges the flap to return to its closed and horizontal orientation, but the top edge of the post will catch under a catch edge of the opening opposite the hinge. This holds the flap open. The user can then drink from the spout. To re-close the valve, the user applies inward force to the outer sidewall (16) below the catch edge. This causes the wall to deflect inwardly and the catch edge to distort outwardly, widening the hole. This releases the post, allowing it to move upwardly so that the flap can spring back to its horizontal and closed position.
