Abstract
Abstract A foam drink tray having improved cup cavities includes a foam base with at least two cup cavities disposed in a top thereof for retaining cups or cans. At least one hand cavity may be formed in a top thereof for the retention by a hand. The side wall of each cup cavity may be shaped several different ways. However, every side wall surface which contacts a cup or can must be chamfered where it meets the top of the tray. The gas escape hole is disposed in the mold such that it is on the chamfer. The hand cavity may be any convenient shape which allows a hand to firmly retain the foam drink tray. A gas relief vent may be formed in one a mold half to facilitate improved flow of foam throughout the mold.
