Abstract

The breast shield includes a flexible collar, which is arranged on the funnel at the end of the funnel facing away from the connection piece, and which is designed to be placed on the mother's breast. The end of the funnel forms a first contact surface, and an end of the collar facing the funnel forms a second contact surface (22), which in a circumferential connecting seam adjoin each other in a blunt way. The funnel has a first wall thickness and the collar has a second wall thickness, wherein said second wall thickness is approximately equal to the first wall thickness. The breast shield can be produced simply and inexpensively, nevertheless allowing a high degree of wearing comfort and a tight fit on the mother's breast.
