Patent ID: 7559094

Claim:
A ventilated adjustable cap for wearing on a user's head, the cap comprising: (a) a crown, the crown having a front side, a back side, a circumferential edge, and an apex, during normal use the front side of the crown being toward a user's forehead; (b) a perimeter band surrounding the circumferential edge of the crown, the perimeter band having a forehead offset, the forehead offset projecting from the remainder of the perimeter band such that, during normal use, the forehead offset generally does not contact the user's forehead, a space between the user's forehead and the forehead offset defining a forehead cavity; (c) a left temple pad and a right temple pad, the left temple pad being on the perimeter band immediately to the left of the forehead offset, the right temple pad being on the perimeter band immediately to the right of the forehead offset, where left and right refer to the user's left and right when the cap is worn on the user's head during normal use; (d) a perforated air passage at the front side of the crown, the perforated air passage providing ventilation to the user's head adjacent the front side of the crown; (e) a forehead water-retentive member, the forehead water-retentive member comprising a porous, absorptive material, the forehead water-retentive member being located in the forehead cavity, the forehead water-retentive member being removably connected to the crown; (f) a crown water-retentive member, the crown water-retentive member comprising a porous, absorptive material, the crown water-retentive member being located at the apex of the crown, the crown water-retentive member being removably connected to the crown; (g) a neck flap connected to the circumferential edge at the back side of the crown, the neck flap comprising a neck flap water-retentive member, the neck flap water-retentive member comprising a porous, absorptive material, the neck flap being removably connected to the crown; (h) an edge gap in the circumferential edge, the edge gap comprising a discontinuity within the circumferential edge; (i) a torsion spring circumventing the edge gap, the torsion spring opposing widening of the edge gap in the direction of the circumferential edge; (j) an elastic band spanning the edge gap; and (k) corrugations on at least a portion of the circumferential edge, the corrugations permitting ambient air to flow between the circumferential edge and the user's head to cool the user; wherein the forehead water-retentive member, the crown water-retentive member, and the neck flap water-retentive member may contain water and allow ambient air to pass through or circulate over each to provide evaporative cooling for the user; and wherein the combination of the edge gap, the torsion spring, and the elastic band help to fit the cap snugly on the user's head.
