A non-spillable drinking container is comprised of a resiliently flexible material with a drinking tube or straw sealably mounted therethrough. The drinking tube or straw is moveable toward and away from the bottom of the container. The lower end of the drinking tube is provided with an elastic diaphragm connected to the bottom of the container. Tension on the drinking tube away from the bottom of the container causes the lower end of the tube to be lifted away from the bottom and perforations in the diaphragm to be stretched open to allow fluid flow through the perforations in the diaphragm and out through the drinking tube. In the absence of tension being applied to the drinking tube causing it to be pulled away from the bottom of the container, the holding of the container upside down or the application of pressure to the walls of the container will not cause liquid to leak from the non-spillable drinking container.
