Beverage container lid having liquid cooling effect

Abstract

Disclosed is a lid for a beverage container including external and internal covers, which may be coupled together to define a cooling reservoir there between to receive and cool hot liquids that may be held in the beverage container. The external cover having ventilation holes and a dispensing spout for dispensing the liquid therein to the user. The internal cover includes a plurality of walls used for directed the hot liquid that enters from the beverage container. A plurality of entrance apertures are disposed in the interior cover, allowing the hot liquid to enter the reservoir. A plurality of dispensing walls cooperate to direct the hot liquid entering through the entrance apertures and to separate the hot liquid from cooled liquid exiting the reservoir through a dispensing aperture disposed in the spout.

       5 . The beverage container lid of  claim 1  further comprising at lease one entrance aperture disposed adjacent to the dispensing guide wall to allow liquid to enter the main cooling reservoir. 
   
   
       6 . The beverage container lid of  claim 1 , wherein the cooling lid is adapted to be fitted on top of a beverage container in a sealing relationship. 
   
   
       7 . The beverage container lid of  claim 1 , wherein the at least one dispensing guide wall includes two dispensing guide walls extending upwardly from the angled wall, and the two dispensing guide walls and the angled wall define a dispensing reservoir. 
   
   
       8 . The beverage container lid of  claim 7 , wherein the dispensing reservoir extends below a bottom of the main cooling reservoir. 
   
   
       9 . The beverage container lid of  claim 7 , wherein the dispensing reservoir is separated from entrance apertures by the dispensing guide walls. 
   
   
       10 . The beverage container lid of  claim 1 , further comprising:
 a suction release port formed in the interior cover to release suction pressure between a beverage container and the main cooling reservoir.   
   
   
       11 . A beverage container lid comprising:
 an exterior cover including:
 a dispensing aperture; and 
   an interior cover including:
 a lower wall; 
 an angled wall; 
 a pair of dispensing guide walls extending upwardly from two sides of the angled wall, the lower wall and the angled wall defining a bottom of the interior cover, wherein the lower wall and angled wall are non-coplanar; and 
   wherein the exterior cover and the interior cover are coupled together to define a main cooling reservoir.   
   
   
       12 . The beverage container lid of  claim 10 , wherein the angled wall extends at an incline below a plane defined by the lower wall.
