ABSTRACT OF THE DISCLOSURE
Disclosed herein is a teat cup assembly for
use with a silicone liner. The one piece shell for the
teat cup assembly has an integral peripheral protecting
wall which projects beyond the end of the cylindrical
shell wall and forms a recess for receiving the cuff of
the liner. The flange protects the end of the
inflation from damage caused by impact with the floor
or other articles in the milking parlor. No mechanical
parts are required to maintain the liner and assembly
in the shell.
