The self chilling liquid container including a bottle having a top portion with an opening therein for filling the bottle and a removable cap, a closed bottom portion and an elongated center portion. An absorbent elastic exterior shell is received around an outer circumference of the center portion and secured thereto. The exterior shell may be permanently attached to the center portion or removably attached. When the exterior shell is saturated with water and is exposed to the atmosphere, the liquid within the shell evaporates at ambient temperature thus chilling the liquid inside the bottle by heat transfer. The chilling effect is substantially increased by airflow flowing past the flexible shell. In this manner, the primary source of heating of a liquid in the container, that is air flow, is changed to a primary source of cooling the liquid. The exterior shell is made of a hydrophilic open-cell elastomeric material that has sufficient thickness and void-volume to absorb several ounces of a cooling medium (i.e., water) and thus can provide an active evaporative cooling capability for the duration of the bicycle ride. In the event that all of the cooling medium evaporates from the shell, the enclosure material will still act as an insulator.
A bottle cover for a liquid bottle used on a bicycle and other outdoor vehicles, the liquid bottle supported by a hanging device mounted on the bicycle, the bottle having a open top portion, an elongated center portion with an outer circumference and a closed bottom portion, a liquid in the bottle cooled by evaporative cooling, the bottle cover comprising:
