30 a of the second cup 30 preferably in locating parting line 24 the line is spaced axially from the rim 22 a distance such that the tapered wall 34 of cup 30 contacts the inner edge of mouth 32 while the bottom 36 of cup 30 is spaced apart from the surface u201c s u201d this allows cup 30 to be forced downward into the mouth 32 of section 26 in a manner such that the tapered wall 34 of the 30 is urged into binding frictional engagement with the inner edge of mouth 32 joined in this manner the cup 30 and the base section 26 form a lightweight compact disposable unit that can be carried conveniently from place to place without concern for their separation as shown in fig5 6 and 7 means other than scoring can be employed to facilitate the division of various types of tapered cups into upper and lower sections 40 and 42 to thereby provide a base comparable to section 26 in the embodiment of fig5 the fracturing means of the invention for dividing the cup into upper and lower sections is provided in the form of a parting wire 44 that is embedded in the wall of the cup 45 with a pull tab 46 attached.
