Low-slip high-capacity teat cup liner

摘要

A hot stone therapy and acupressure roller including a specially designed rod where hollow, cylindrical stones, along with acupressure pins, are spaced along the rod. As the rod is applied to the body, the attached stones roll and acupressure may be applied. Targeted acupressure can be applied on either side of the rod, and the acupressure pins serve to hold the cylindrical stones and spacers in place. The stones can be inserted onto the rod or used individually. The stones can be used to conduct a cold and/or hot stone massage. Additionally, each end of the rod is shaped for use as a massage tool. When using either end of the rod as a massage tool, the acupressure pins serve to improve grip and increase leverage.

主权项

1. A milking teat liner for use with a teat cup assembly including a rigid shell as part of the teat cup assembly comprising:
a head having a mouth opening and a generally cylindrical skirt having an inner surface and an outer surface said skirt depending downwardly from said mouth opening, a barrel depending downwardly from said head, said barrel extending axially along an axis for receiving a teat inserted axially thereinto through said mouth opening of said head, said barrel having a barrel wall wherein said barrel wall acts with said inner surface of said skirt to define a circular slot adapted to frictionally receive the shell; wherein said barrel wall has a reinforced sidewall regions that protrudes on an external surface of the liner to frictionally receive the shell; wherein a percentage of a total sidewall that is reinforced is substantially similar to a percentage of the total sidewall that is unreinforced; a scalloped skirt extension distal to said mouth opening to form a suction chamber between said skirt and said shell to increase friction between the skirt and the shell, to prevent twisting of the liner within the shell during use, and to reduce contaminants from entering the shell; wherein the suction chamber is a ring-shaped concave portion at an end of the skirt distal to said mouth; wherein said concave portion is on an inner surface of said skirt adjacent the shell, and a short milk tube depending downwardly from said barrel.
