An easily cleanable liquid container includes a straw having a pivotably mounted internal one-way spill preventing valve and a closable drinking spout with an overmolded drinking tip. The pivotably mounted internal one-way spill preventing valve is retained in a pivotable straw nut that is pivotably attached to a straw tube, which allows easy access to internal straw components for easier cleaning. The overmolded drinking tip and a wiper seal limit the number of cracks and crevices that may collect dirt or other contaminants.
