Abstract
A jar, preferably for a domestic blender, is provided with an external thread at a lower end for engaging with an internally threaded base member. The threads have a varying radial position along the axial length of the threaded area to assist in the assembly of the two parts and to prevent cross threading. In the disclosed embodiment, the jar has a frusto-conically shaped lower portion on which a constant height thread is formed. The base member has a cylindrical wall with a thread having a varying radial height to complement the position of the jar thread.
