The invention relates to a teat cup (1) comprising a first end portion with an opening (3) to a recess (4) for receiving a teat of a milking animal. The teat cup (1) comprises an outer grip surface to be gripped by an operator during a detachment process of the teat cup (1) from a teat, and detaching means comprising a press surface (16b, 20b, 22b) which consists a part of said grip surface, and pressure equalizing means adapted to establish atmospheric pressure in the recess (4) when the press surface (16b, 20b, 22b) is subjected to a predetermined pressure force (19). The pressure equalizing means comprises an air channel (15) having an extension between an inner opening (15a) to the recess (4) and an outer opening (15b) to ambient air, and a mechanism adapted to open the air channel (15) when the pressure surface (16b, 20b, 22b) is subjected to said predetermined pressure force (19). |
