Abstract
A jetter cup for washing milking equipment includes a cup having a sidewall and a bottom wall defining therein a cavity, a tube having a passageway, and an annular lip having a central opening. The jetter cup facilitates insertion of a mouthpiece of a teat cup liner into the cavity by the provision of ramping bosses circumferentially spaced around the outer surface of the lip, a circumferentially extending groove along the inside of the sidewall at the junction between the lip and the sidewall, and the provision of a plurality of upright ribs along the sidewall which preferably extend downwardly to the bottom wall. When the mouthpiece of the liner is inserted into the cavity, the lip snaps back into sealing relationship around the shell of the teat cup to provide a gap between the sidewall and the skirt of the mouthpiece to permit cleaning and rinsing solution to circulate around the mouthpiece including the lower margin thereof. The bosses lessen frictional engagement between the mouthpiece and the lip during insertion and the groove facilitates the lip in yielding and then returning to a sealing position without the need for twisting or pulling on the teat cup.
