Abstract
An insulated cup includes a tapered side wall that defines an array of spaced, parallel ridges separated by grooves. A label is supported by the ridges around the exterior of the cup to define an array of air gaps in the grooves between the ridges. These air gaps provide thermal insulation tending to reduce heat flow through the label into or out of the cup, and the side wall includes solid resin outer layers and a foamed resin central layer to improve thermal insulation further.
