I assume you mean the chemical cold packs that you twist and shake which become cold immediately. Those cannot be reused since breaking the liquid vial and shaking mixes two chemical ingredients and result in an irreversible chemical reaction. The chemical cold packs uses the endothermic reaction of ammonium nitrate and water to cool down quickly. When one breaks a tube inside the pack the ammonium nitrate is released allowing it to mix with the water.
Technically the reaction can be reversed by dehydrating the ammonium nitrate, however it is generally not feasible to do so, hence there are no "reusable" cold packs.

What are the differences between hot packs and cold packs?
Hot packs are used to provide relief for muscle stiffness, promote blood flow, and relax muscles. Cold packs are used to reduce inflammation, numb pain, and help minimize swelling. They work by different mechanisms and are used at different stages of injury.
Why do hot packs and cold packs eventually return to room temperature?
Hot packs and cold packs eventually return to room temperature because of the process of thermal equilibrium. This means that the packs exchange heat with their surroundings until they reach a balanced temperature. Heat flows from the hotter pack to the cooler room, or vice versa, until both reach the same temperature.
Why hot and cold packs are very convenient to use?
Both types (hot and cold) of packs can be easily transported and used in travel. They do not take up a lot of room in a bag or box. If someone were to get hurt, a cold pack can quickly be used to help them. The same goes with a hot pack.
