摘要:
This invention provides a thin and discreet coolant device, and single and multiple unit dispenser containers containing the same. The coolant device comprises a first packet being comprised of a waterproof or water-resistant material containing water therewithin and further comprising a fold and further adapted to have a selectively permanent connection between external and internal layers of said fold, such that upon applying a force to laterally extend the ends of said packet, a rupture of said first packet occurs allowing for the leakage of the water contained therewithin. The coolant device further comprises a second packet which encases said first packet, comprising an exterior and interior layer, wherein said interior layer is comprised of an absorbant material and said exterior layer is comprised of a waterproof or water-resistant material and wherein an amount of powdered urea is located within an interior of said second packet. Upon lateral extension of the sides of the second packet, a rupture of said first packet occurs allowing for the leakage of the water contained therewithin and its exposure to said urea located within said second packet, which exposure results in an endothermic reaction resulting in an outer surface of said second packet becoming cooler to the touch than an outer surface temperature prior to said rupture. Use of the coolant devices to provide cooling to a skin surface on demand is described, as well.
