Abstract
A self-adhering cold pack has an envelope defining a sealed cold pack volume. A cooling agent is positioned in the cold pack volume. A bandage sheet is fixed to the envelope by a bandage adhesive. The bandage sheet defines mounting tabs linearly extending from the envelope outer perimeter. The mounting tabs support a bandage adhesive for temporary adhesion of the cold pack to the skin surface of a patient.
