BACKGROUND1. Field of the Invention
The present invention relates generally to a device for receiving condensation, and more particularly, to a device for receiving condensation that is coupled or integrally formed with a drinking cup.
2. Background
In the use of drinking cups, especially those made from glass or a polymer, condensation can occur when certain atmospheric conditions are satisfied. Condensation is an exothermic process by which water vapor in the air is changed into liquid water, i.e., the reverse of evaporation, because the surface on which the water vapor condenses removes the thermal energy from the surrounding water vapor, thereby condensing the surrounding vapor into liquid water. Said another way, condensation of water in the air occurs when water vapor is cooled to its saturation limit and the molecular density of the water vapor reaches its maximal threshold. When this stage of the water cycle occurs, and water vapor in the air comes into contact with something cool, such as the outside of a cold drinking cup, the water molecules slow down, get closer together, and condense into water droplets.
In the drinking cup context, water vapor can condense onto many different types of drinking cup surfaces. For instance, water vapor can condense onto glass, ceramics, metals, papers, wax, polymers, or any other material that forms a drinking cup. Under constant pressure, temperature, and dew point, condensation typically occurs at a faster rate on higher density materials, such as glass, than on lower density materials, such as expanded polystyrene, due to the differing surface tensions of the materials. After condensation in the form of water droplets has formed on the outer surface of a drinking cup, the water droplets will typically form into larger droplets and, due to gravity, will bead along the outer surface of the cup to the base of the cup, which may be resting on any number of surfaces including a desk, a table, or any other surface. After condensed water pools along these surfaces, cleanup of the water is required, and damage may result with surfaces that are not waterproof.
Additionally, the flow of condensation along the exterior of a cup may be exacerbated during drinking, when the cup is inclined and inverted relative to its resting configuration. In that case, the condensation may flow toward a lip of the cup, getting the user's hand and/or face inadvertently wet.
Currently, methods exist for reducing the amount of condensation that results on the outside of a drinking cup. For instance, a drinking cup may include both an inner wall and an outer wall separated by an air gap. The air gap inhibits the temperature of the outer wall from being lowered to the temperature of the liquid inside the cup, thereby reducing the condensation that forms on the outer surface of the cup. In other cup designs, insulation is added between the inner surface of the cup and the outer surface of the cup to similarly inhibit the temperature of the outer surface from lowering to the temperature of the inner surface. However, these methods of reducing condensation are costly, due to the more complex design of the cup, and are difficult to implement with existing cups. Moreover, these solutions to reducing condensation on the outer surface of specially designed cups do not completely eliminate resulting condensation, and, importantly, these designs do not prevent the even-diminished resulting condensation from beading down the outer surface of the cup to the surface upon which the cup is resting.
There is therefore a need for an effective device that is either coupled with a cup or attachable to a cup, which eliminates resultant condensation from pooling at the base of a cup on the surface upon which the cup is resting.
