Condoms for women

一种女用避孕套，该女用避孕套具有一个扩张环(6；26)，它位于开口端(1)的紧邻处，用于将避孕套扩张至最大直径，以便将开口端保持在阴道之外；和一个管状部分(3)，它延伸于扩张环和封闭端之间，其大小制成能形成宽松地套在阴茎上，并由一系列、如3至5个周向凹槽(5)形成，凹槽宽度约为0.8厘米，深度约1厘米，这样，避孕套自然折叠成风箱状形状，以便避孕套在使用前折叠成基本为平板的状态。 A condom has a ring (6) adjacent the open end (1) for expanding the condom to a maximum diameter to maintain the open end outside the vagina, and a tubular portion (3) extending between the ring and the closed end is of a size to form a loose fit around the penis and is formed with a series of circumferential grooves (5), e.g. 3 to 5 grooves around 0.8 cm wide and 1.0 cm deep, so that the condom naturally folds in a bellows like manner for the condom to collapse to a substantially flat condition prior to use.
