Abstract: A cup holder sleeve is formed in accordance with the method comprising the steps of feeding corrugated paperboard into a lithograph press, the corrugated paper including a first surface and a second surface; engaging the corrugated paperboard with an impression cylinder having a perforated metal plate secured thereabout such that the corrugated paperboard is de-bossed with air channels formed in the first surface of the corrugated paper; die cutting the corrugated paperboard into a long, flat band; and gluing first and second side edges of the band at overlapping surfaces of the first and second side edges to create the resulting cup holder sleeve with the first surface defining the inner surface of the resulting cup holder sleeve.

Abstract: A cup holder sleeve is formed in pre-assembled, flat-folded form by die cutting a long, flat band from paperboard material. The flat sleeve has fold lines scored into the band at spaced apart positions tapering toward each other, and side edges at opposite ends of the band. The opposite ends are folded flat at the fold lines so that the side edges overlap each other and are glued together at their overlapping surfaces. Within the flat sleeve are two “D” shaped flaps that when folded back 180 degrees upon the sleeve itself produce a double paperboard layer of heat protection for the fingers when placed on the cup.
