The present invention relates to a molded, one-piece, chilling pitcher with a compartment for holding a beverage, and an integral dividing wall that forms a wedge-shaped cooling chamber for holding a cooling medium such as ice. The main body of the pitcher is formed by a conical exterior wall and an integral base. The cooling chamber is formed between the arcuate shaped exterior wall and the dividing wall to produce a wedged-shaped configuration that facilitates the filling and emptying of ice into and from the chamber. This wedge-shape and the relatively wide radius of the dividing wall allow ice cubes or chips to be poured into the cooling chamber in a relatively compact manner, and allow the surface of the ice to flushly engage the surface of the dividing wall to improve the cooling rate of the pitcher. The arcuate shape of the dividing wall and wedge shape of the cooling chamber help minimize the volume of the cooling chamber and maximize the surface area of the dividing wall to facilitate the transfer of heat between the beverage and ice and improve the cooling rate or power of the pitcher. The sides of the dividing wall are integrally formed with the exterior wall of the pitcher to provide the structural stability to allow the dividing wall to extend to and be thinner and wider near the top of the pitcher to further improve the cooling rate and efficiency of the pitcher. The dividing wall is vertical or slightly pitched back to help prevent ice and water from spilling into the beverage compartment when pouring the beverage from the pitcher.
