A cup includes a spout integrally formed in an upper zone of the cup's side wall, the spout including a fluid directing channel extending upwardly and outwardly from an inner surface of the side wall at an angle relative to a vertical axis of the cup which causes the velocity of fluid flow to increase as the fluid enters the channel and flows towards a distal tip of the spout, thereby reducing the required degree of tilt of the cup when pouring or drinking fluids therefrom. A lip on the distal spout tip includes acute angled surfaces which, in conjunction with the increased flow velocity of the fluid through the spout, cause the fluid to separate from the cup when pouring, thereby discouraging flow of the fluid down along an outer surface of the cup. A plurality of shoulders formed at spaced intervals on an outer side of the spout create a fluid capture area for entrapping droplets of fluid which fail to detach from the cup and flow over the lip and down the side of the cup.

[ What is claimed is:] [1.] A cup for containing fluid comprising:a bottom and a side wall structure extending upwardly from the bottom to an upper zone including a rim surrounding an open top of the cup and a central vertical axis extending from said bottom and through an interior fluid containment

[ What is claimed is:] [1.] A cup for containing fluid comprising:a bottom and a side wall structure extending upwardly from the bottom to an upper zone including a rim surrounding an open top of the cup and a central vertical axis extending from said bottom and through an interior fluid containment chamber of said cup, said side wall structure including an inner surface and an outer surface, said inner surface being disposed at a first angle relative to said central vertical axis;a spout integrally formed with said side wall structure, at said upper zone, and forming a spout opening in said open top of said cup, said spout including a top lip having an inner lip surface and a top lip surface, said top lip extending outwardly from said rim, at opposite sides of said spout opening, to a distal spout tip;means for detaching fluid from said top lip when the fluid is poured from said spout to thereby discourage fluid from flowing around said top lip and along said outer surface of said wall structure and including an acute angled edge formed between said inner lip surface and said top lip surface;means for detaching fluid from said outer surface of said spout and including a plurality of shoulders each being defined by a change in an angle of said outer surface; andfluid capture means on an outer surface of said spout below said distal spout tip for entrapping fluid which flows down said outer surface of said spout, to thereby prevent fluid from flowing down along said outer surface of said wall structure.
