Cup assembly
First Claim
1. A valve for a cup having a cap and an inner volume, the valve comprising:
- a passageway having first and second ends, said first end being open and in fluid communication with the inner volume of the cup, said second end being open and in fluid communication with atmosphere, wherein said passageway has a cross-sectional area that is small enough to substantially prevent air from flowing past fluid in said passageway when the cup is tilted or inverted, wherein said passageway is disposed in a first planar section having a first longitudinal axis, wherein the cap is disposed in a second planar section having a second longitudinal axis, and wherein said first and second longitudinal axes are substantially parallel.

Abstract
A cup for reducing or eliminating spillage or shake-out is provided. The cup has a cap and a spill and shake-out inhibiting element. The spill and shake-out inhibiting element is a dispensing tunnel, which provides for the formation of a pressure differential between the inside of the cup and the atmosphere when fluid begins to flow through the dispensing tunnel. The pressure differential, when it reaches a predetermined level, prevents further flow or movement of the fluid through the dispensing tunnel until additional suction is applied by the user. The diameter of the dispensing tunnel is small enough to effectively prevent air bubbles from flowing past the fluid in the dispensing tunnel.

49. A bottle assembly comprising:
-
a cap having a top wall, a circumferential sidewall, and a first connecting structure, said circumferential sidewall surrounding said top wall, said first connecting structure being disposed on said circumferential sidewall;
a cup having an inner volume and a second connecting structure, said first and second connecting structures connecting said cap with said cup; and
a valve having a passageway with first and second ends, said first end being open and in fluid communication with said inner volume of said cup, said second end being open and in fluid communication with atmosphere, wherein at least a portion of said top wall is recessed with respect to said circumferential sidewall to form a lip, wherein said lip at least partially circumscribes said top wall and has an opening therethrough, and wherein said opening is in fluid communication with said second end of said passageway. - View Dependent Claims (50, 51, 52)
