Party hat

A hat assembly comprising:

• a first hat comprising:
• a cone-shaped first hat body having opposite first upper and first lower end portions, the first lower end portion being wider than the first upper end portion, the first upper end portion forming a first tip of the cone-shaped first hat body, the first lower end portion configured to rest on the head of the person, the first hat body extending upward from the first lower end portion to the first upper end portion, the first hat body having a cone-shaped first hollow interior above the first lower end portion, the lower end portion having an opening for receiving a portion of the head of the person,
• a first illumination system including a first light source, the first light source being supported by the first hat body, the first light source being arranged to illuminate the first hollow interior of the first hat body, the first light source mounted in the first hollow interior at the first tip and oriented to face downward toward the first lower end portion to emit light toward the first lower end portion to illuminate the first hollow interior,
• at least a portion of the first hat body being formed of a first light-transmissible material configured to permit light from the first light source to pass from the first hollow interior to an exterior of the first hat body to be visible from the exterior of the first hat body,
• wherein the first light source is in open communication with the opening, and the first light source is arranged with respect to the opening, such that the light emitted by the first light source reaches the opening and illuminates a majority of the portion of the head of the person when the first hat is on the head of the person and the first light source illuminates the first hollow interior;
• a second hat comprising:
• a second hat body having opposite second upper and second lower end portions, the second lower end portion configured to rest on the head of the person, the second hat body extending upward from the second lower end portion to the second upper end portion, the second hat body having a second hollow interior above the second lower end portion,
• a second illumination system including a second light source, the second light source being supported by the second hat body, the second light source being arranged to illuminate the second hollow interior of the second hat body, the second light source positioned adjacent to the second upper end portion and oriented to face downward toward the second lower end portion to emit light toward the second lower end portion to illuminate the second hollow interior,
• the second hat body including at least one second section of light-transmissible material configured to permit light from the second light source to pass from the second hollow interior to the exterior of the second hat body to be visible from the exterior of the second hat body,
• wherein the first and second hats are in a nested configuration such that the second hat is nested in the first hollow interior of the first hat;
• wherein the second hat has a height extending between the first upper and first lower end portions, at least a majority of the height of the second hat being disposed within the first hollow interior of the first hat.

A hat for a head of a person, the hat comprising:

• a cone-shaped hat body having opposite upper and lower end portions, the lower end portion being wider than the upper end portion, the upper end portion forming a tip of the cone-shaped hat body, the lower end portion configured to rest on the head of the person, the hat body extending upward from the lower end portion to the upper end portion, the hat body having a cone-shaped hollow interior above the lower end portion, the lower end portion having an opening for receiving a portion of the head of the person,
• an illumination system including a light source and a switch configured to turn the light source on, the light source being supported by the hat body, the light source being arranged to illuminate the hollow interior of the hat body, the light source mounted in the hollow interior at the tip and oriented to face downward toward the lower end portion to emit light toward the lower end portion to illuminate the hollow interior, the switch including an actuator disposed above the lower end portion and adjacent the upper end portion, the switch configured to be actuated by the person to turn the light source on,
• at least a portion of the hat body being formed of a light-transmissible material configured to permit light from the light source to pass from the hollow interior to the exterior of the hat body to be visible from the exterior of the hat body,
• wherein the light source is in open communication with the opening, and the light source is arranged with respect to the opening, such that the light emitted by the light source reaches the opening and illuminates a majority of the portion of the head of the person when the hat is on the head of the person and the light source illuminates the hollow interior.
