ABSTRACT:
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.
