Conventional systems use a vacuum source as negative pressure to induce the expression of breast milk and can result in the elongation/distention of the breast nipple in an axial direction that is uncomfortable and inefficiently expresses breast milk. The invention provides a breast cup for placing a breast in fluid communication with first and second containers each having openings with different diameters. The breast cup has a funnel for receiving the breast and a housing having a base connected to the funnel. The base has a circumferential wall, a flange extending inwardly from said circumferential wall to define an opening, first threads, and second threads. The first and second threads are concentrically disposed along said base and selectively engage with first and second containers respectively. |
