Abstract

The head end portion of a milking inflation adapted to fit over the upper end of a teat cup shell includes a peripheral cuff adapted to surround and sealingly engage the upper rim of the shell and a substantially flat, relatively thin web section extending radially inwardly from the cuff and terminating in a raised, rounded deed which defines a circular central opening or mouth for receiving a cows' teat. A plurality of circumferentially-extending ribs are formed integrally with and extend radially outwardly from the bead and also are formed integrally with and project axially outwardly from the exterior surface of the web section. These ribs add sufficient stiffness to the web section to substantially increase its tendency to resist inward and outward deflections from its original flat and horizontal position and to return the web section to its original position if deflected.
