Abstract
A drinking vessel formed of a separable outer shell and inner shell which form a fluid flow path therebetween when the inner shell is received in the outer shell. Removal of the inner shell renders the flow path accessible for cleaning. The outer shell is transparent in the vicinity of the flow path to display fluid flow through the path. Embodiments having various configurations of flow paths are disclosed. An embodiment including a mechanism for puncturing a disposable inner shell to provide access between the flow path and interior of the inner shell is also disclosed.
