A breast shield (4) has a tubular connector (40) and a funnel (42) that is integrally formed thereon and is intended for resting on a mother’s breast, wherein the funnel (42) widens toward the free side thereof which faces away from the connector (40), and wherein there is a passage (43), which extends continuously from a breast-side end of the funnel (42) as far as a pump-side end, facing said breast-side end, of the connector (40), and which serves to apply a vacuum to the mother's breast and for the flowing away of the expressed breast milk. According to the invention, the funnel (42) is of more flexible design than the connector (40), and the funnel (42) has a main region (420) extending over a substantial part of the length thereof with a first opening angle (α1) of the passage (43), and a breast-side end region (421) with a second opening angle (α2) of the passage (43). When not in use, the first opening angle (α1) is smaller than the second opening angle (α2), wherein, in the use state, at least the first opening angle (α1) can be enlarged by axial pressure on the breast shield (4). Said breast shield is pleasant to wear and minimizes the dead volume.一種胸部防護罩(4)，其具有一管狀連接器(40)和一漏斗(42)，其整體地形成在胸部防護罩(4)上並且係企圖用於放置在母親的胸部上，其中該漏斗(42)朝向其遠離連接器(40)的自由末端側擴張，且其中具有一通道(43)，該通道(43)從該漏斗(42)的一胸部末側端連續地延伸至該連接器(40)一面對該胸部側末端的泵側末端，且該通道(43)作為施加一真空至該母親胸部且用於讓被擠壓出的母乳流出。根據本發明，該漏斗(42)係為比該連接器(40)更撓性的設計，且該漏斗(42)具有一主要區域(420)和一胸部側末端區域(421)，該主要區域(420)過該漏斗(42)一實質部分的長度且具有該通道(43)的一第一開口角度(α1)，且該胸部側末端區域(421)具有該通道(43)的一第二開口角度(α2)。在不使用時，該第一開口角度(α1)係小於該第二開口角度(α2)，其中，在使用狀態中，至少該第一開口角度(α1)可藉由在該胸部防護罩(4)上的軸向壓力被擴大。該胸部防護罩係可舒適穿戴且將無效容積最小化。
