Abstract
A passive milk collection device for storing milk comprises a flexible inner member including a nipple hole for receiving a nipple, and in which, in use, part of the rear surface of the inner member is configured to securely seal onto a user's breast. The device includes a removable rigid outer member configured to attach onto the front surface of the inner member and to provide a free air space around the nipple area for storing milk from the nipple. The circumference of the outer edge of the rear surface of the flexible inner member is substantially larger than the circumference of the rigid outer member.
