Abstract
A lid (18) for a drinking container (14) includes an engagement means (26) for removably securing the lid (18) to the drinking container (14). The lid (18) is formed as a one piece unit and has a deformable spout (20) with a liquid outlet (46). The one piece lid is further provided with an air inlet (22) for the ingress of air into the container (14). Defamation of the spout (20) effects opening of the liquid outlet (46) and the air inlet (22). The spout (20) may be disposed in a forward position on the lid (18). The container wall may lean in the forwards direction when the container is seated on its base (16) on a level surface.
