Abstract
A sippy cup stacking system comprising multiple substantially identical sippy cups having sippy spout lids that can be mated with the bottom of a first cup while attached to the top of a second cup. Each cup includes a bottom with an annular recess containing a central locking plug capable of mating with a central locking stem protruding from a lid on another cup. The sippy spout on each lid is radially offset from the locking stem and fits into and can move circumferentially in the annular recess on the bottom of the cup to which it is being mated, until the spout is fully enclosed by the bottom of the mated cup.
