Patent attributes
A personal cooling device adapted for suspension from the rear strap of a cap. The device includes an elongated pouch member configured to hold a coolant pack, and a suspension member extended above an open upper end of a second side of the pouch. Fastening means are provided such that the suspension means can be looped over the strap of the cap and secured to the pouch, thereby securing the pouch on the cap. A second suspension member, extending from a side of the pouch, can be used to hang the device from a cap in a horizontal configuration. A coolant pack enclosed in the pouch cools the user. To prevent pooling of coolant gel, the coolant pack preferably has a plurality of closed compartments. The device can be used in an exchange system in which warm packs are replaced with frozen packs, such as for a rental fee.
