Abstract
The expansion ring type milking inflation is formed from an elastomeric material and has a tapered upper end portion which serves as a mouthpiece for receiving cow's teat. The upper end portion includes an expansion ring-receiving portion adjacent the juncture with the main body and terminates in a rounded bead which defines a circular opening or mouth when the expansion ring is inserted. The upper end portion also includes an annular web section of reduced wall thickness adjacent the bead which serves to reduce transmissions of distortions caused by swelling to the bead and a plurality of circumferentially-spaced, reinforcement ribs formed integrally with and extending longitudinally between the expansion ring-receiving portion and the bead and also formed integrally with and projecting radially outwardly from the web section.
