ABSTRACT:
A tapered cup having an outwardly rolled lip includes insulating bodies integral with the outer face of the wall of the cup. Thermally conductive channels are among the insulating bodies and have an insulating value that is less then the insulating value of the insulating bodies. The cup can include a groove below the outwardly rolled lip in the inner face of the cup wall. The insulating bodies can be configured as alpha numeric indicia and the outer wall of the bodies or cup can be provided with bumps to aid in stacking of two or more cups. The cup can include a tapered lid with an outwardly flared lip that seats against the inner wall of the cup and does not extend over the lip of the cup. The lid can include a locking ring below the outwardly flared lip of the lid that is adapted for insertion into the groove in the cup. The lid further includes a fluid port.
