ABSTRACT:
A ball pouch has a hollow defined by walls comprising a plurality of linked cells packed with a heat storage medium. The medium is a mix including phase change material ("PCM") having a phase change temperature within the preferred range of 130-150.degree. F. Preferably the PCM mix is in free-flowing powder or gel form, and includes paraffin, ultra fine silica, and an ingredient to convert microwaves, as from a microwave oven, into heat. The pouch is charged by heat soaking it, preferably in a microwave oven, until the PCM has fully absorbed its latent heat of fusion. A golf ball pouch according to this invention can be packed with a plurality of golf balls. Once charged the pouch heats golf balls contained therein to a desired temperature above ambient and keeps them well above ambient for more time than it takes to play a round of golf. The temperature to which the balls are heated depends on the phase change temperature of the selected PCM mix. The pouch is preferably snugly enclosed in a flexible, insulated container to reduce the rate of heat loss from the pouch, thus keeping the balls warmer for a longer time. The combination pouch and pouch container comprises the ball caddy of this invention.
