The skirt (22) is configured so that sufficient pressure is applied to the teat (14) to ensure positive sealing between the teat and the first skirt (22). The skirt (22) is located in board of the periphery of, and depends from, upper wall (26) of cap (20). Inner surface (28) of skirt (22) together with the portion of the upper wall (26) bound by the skirt (22) defines a recess (32) for engaging a second portion (30) of the teat (14).
