Abstract
A 'honeycombed' insulative sleeve is positionable around a portion of a beverage cup side wall. The sleeve is made from a preform which includes a plurality of circumferentially spaced-apart rows of generally longitudinally oriented and off-set slits. The slits thereby allow the sleeve to expand circumferentially when portioned on a portion of the beverage cup side wall and, by virtue of such circumferential expansion, thereby form the insulative honeycomb structure therearound.
