A non-spillable drinking container is manufactured in assemblable parts which provide stackability and reduced manufacturing costs. The drinking container utilizes a perforated expandable diaphragm mounted or formed over a base plate. The container is preferably frustro-conical in shape to provide stackability. A drinking tube is attachable to the expandable diaphragm and a top is sealably mountable over the tube. Drinking is accomplished by pulling upwardly on the tube to expand the diaphragm opening the perforations therein, allowing fluid flow through the perforations and up the straw to the mouth of the drinker.
