摘要

Bra has cup interlinings, each of which has two first chambers and one second chamber. The two first chambers (22) are filled with liquid (24) while the second chamber (23), located between the first two, is filled with air. Each interlining (20) has two outer layers (21A, 21D) and two inner layers (21B, 21C). The periphery of each outer layer is joined to the inner layer periphery to form the closed interlining.
