Self-adhering cold pack

A self-adhering cold pack comprising:

• a liquid impermeable envelope defining a closed internal cold pack volume and defining an outer perimeter edge;
• a cooling agent comprising substantially water in said cold pack volume;
• a flexible bandage sheet having a first surface and an opposite second surface, said second surface engaging said envelope and said sheet having securement tabs extending from said perimeter edge;
• and
• a hypo-allergenic adhesive on substantially all of said second surface for mounting said sheet to said envelope and for temporary adherence of said cold pack to a skin surface by said securement tabs.

A self-adhering cold pack comprising:

• a liquid impermeable envelope defining a closed internal cold pack volume and further defining an outer perimeter edge, said envelope having an upper envelope layer, a lower envelope layer, and a divider wall extending between said upper and lower envelope layers to divide said internal cold pack volume into a plurality of separate chambers, said divider wall rupturable;
• a cooling agent in said cold pack volume comprising a first reactive component in one of said chambers, and a second reactive component in another of said chambers, said first and second reactive components having an endothermic reaction when mixed;
• a flexible bandage sheet mounted to said envelope and having securement tabs extending from said perimeter edge;
• and
• a hypo-allergenic adhesive on said securement tabs for adherence of said cold pack to a skin surface.
