  • Patent number: 12161173
    Abstract: A breast pump bra cup is provided. An elastic compression area can form an elastic compression force almost perpendicular to a surface of a cup and pointing to the inside of the cup when the bra is worn. A length direction of a first opening is the same as that of a second blind opening. The first opening, the first blind opening and one end of the second blind opening in the length direction intersect and are in a connected state. One end of a first blind opening limit line is connected with an O1 end of the second blind opening, so that the first blind opening coincides with the second blind opening in a direction close to the O1 end and is in a connected state. The opening on the bra cup can be stuffed into a breast pump flange while the length is smaller.
