Abstract:
A cup system for providing a thermal isolating structure comprising a pair of cups, each of said cups having:a. an open cavity defined by a continuous side wall and a bottom wall formed at one end thereof;b. a first protrusion formed in said bottom and extending a first predetermined distance into said open cavity; and,c. a pair of second protrusions formed in said bottom wall on opposing sides of said first protrusion and extending into said open cavity a second predetermined distance, said second predetermined distance being less than said first predetermined distance, wherein (1) said pair of cups are nestable when a first of said pair of cups is inserted into said open cavity of a second of said pair of cups with said first and second protrusions of said first cup respectively aligned with said first and second protrusions of said second cup, and (2) said first cup is supported within said open cavity of said second cup on a top surface of said first protrusion of said second cup when said second protrusions of each of said cups are respectively non-aligned and thereby space said side wall of said first cup from said side wall of said second cup to provide thermal isolation therebetween.
