Abstract
The rims of two plastic cups are heat sealed to each other by means of an interposed, plastic-coated aluminum foil which seals the cavities of the two cups and their contents from each other and constitutes the sole fastening element connecting the cups. At least one integral, plastic piercing thorn projects from the flexible bottom wall in the cavity of one cup, and manual pressure applied to the exposed outer face of the bottom wall may cause the blade to pierce the aluminum foil so that the contents of the two cavities may be mixed and thereafter discharged through a normally plugged spout on one bottom wall.
