Problems solved by technology

However, a disadvantage of such triangular or polygonal teatcup liners is that they do not adequately break the vacuum at the cuff of the liner, resulting in slower milking

Embodiment Construction

[0061] figure 2 A longitudinal cross-sectional side view of a first type embodiment of a teat cup liner 1 according to the invention is disclosed. As shown in the figure, the liner 1 has a longitudinal shape extending along a longitudinal axis (x).

[0062] In all embodiments of the present invention, the teat cup liner 1 includes a tube 2 with a polygonal cross-sectional shape composed of an upper tube 3 and a lower tube 4.

[0063] image 3 A polygonal cross-sectional view at the top 5 of the upper cylinder 3 along the section line 3-3 is shown. Figure 4 A polygonal cross-sectional view along the section line 4-4 is shown, in which the bottom part 6 of the upper cylinder 3 is connected to the top part 7 of the lower cylinder 4. Figure 5 A polygonal cross-sectional view along section line 5-5 is shown.

[0064] The barrel 2 defines an internal space 8 with an inner surface 9 which is used in the upper barrel 3 to receive teats.

[0065] The upper cylinder 3 has a first length (L1)...

Abstract

A teatcup liner (1) includes a head defining a mouthpiece, a barrel (2) with an upper barrel (3) joined to a lower barrel (4), an outlet portion that extends downward from the lower barrel co-operateswith the shell of the teat cup. In a relaxed state, the barrel has a polygonal cross-sectional shape, with the lower barrel having a flexibility for closing during the liner collapse phase of the milking operation greater than a flexibility of the upper barrel such that corner portions (19) of the lower barrel are weaker than the corner portions of the upper barrel thereby assuring the lower barrel collapses first to create an upward wave movement of the lower barrel towards the upper barrel that securely collapses the upper barrel onto the teat to provide an enhanced teat massage and relievecongestion in the teat tissue.

Description

Technical field [0001] The present invention provides a teat cup liner with a barrel that provides enhanced teat massage and relieves hyperemia in the teat tissue during a milking operation. The teat cup liner is configured to be installed in the outer shell of the teat cup for use with the teat of the animal in the milking operation. [0002] The teat cup lining provides that during the lining collapse phase of the milking operation, when the atmosphere or a secondary pressure less than the milking vacuum is allowed to enter the pulsation chamber, the lower barrel part collapses, generating upward wave motion, which reduces the impact of the teat cup lining. The upper barrel portion reliably collapses to the nipple, and thus avoids any chance of the barrel pressing down on the lymph when the barrel collapses. Background technique [0003] figure 1 Shows one cycle of the milking operation. During the milking operation, a vacuum level is applied to the inner space of the barrel co...
