Abstract:
1. A lid for a container, comprising of, a uniquely designed and developed formed unit which when snugly and securely mounted on an associated mating container, acts as a cooling device by drawing the cooler outside ambient air into the container through a strategically placed cooling air-flow hole and then this cooler air is drawn up along with the hot liquid as it is sipped through the lid's drinking hole, thus lowering the temperature of the hot liquid by the action of the ambient air outside the cup being pulled down into the cup through the cooling air-flow hole and then continuing up through and out the drinking hole in conjunction with the hot liquid creating a flow though action, a mounting portion for engaging with an associated container to form a snug fit, a raised portion forming a drinking area plane, a drinking hole at the top of the drinking area plane, an angular raised portion adjacent to and raising above and away from the drinking hole area on the side of the drinking area plane containing the drinking hole, an angular recessed portion with its' deepest position at or above the plane of the lid rim and toward the side on which the drinking hole is located, a cooling air-flow hole located in the angular recessed portion and on a plane slightly lower than that of the drinking hole plane and in line along the radius on which the drinking hole is located, a cooling air-flow hole of comparable size to the drinking hole, a cooling air-flow hole located close enough to the drinking hole to allow the cooler ambient air outside of the cup to be pulled into the cup by the vacuum action created by the sipping action when drinking from the drinking hole, a cooling air-flow hole located far enough away from the drinking hole to allow thermodynamic properties to take affect on the hot liquid as the cooler ambient air outside the cup is pulled into the cup and then flows concurrently out of the drinking hole with the hot liquid reducing the temperature of the hot liquid, a gradually raised portion leading away from and opposite to the drinking hole and cooling air-flow hole, a portion returning to a plane at or below the drinking area plane and on the opposite side of said lid, and said HOT DRINK CUP LID WITH COOLING AIR-FLOW being designed for ease in use and economically viable for manufacture and marketing.
