Abstract
Abstract A container such as a nursing container, fabricated from a single web of flexible material, is provided. The container maintains the nursing fluid or other liquid and an attached nipple or other access assembly in a sterile condition until use. The walls of the single web container enclose the nipple during filling, packaging, and shipping, and separate the access assembly from the container contents until accessed for use. Sterility is readily maintained by single point fabrication and filling. A method is provided for fabricating the container from a single web of flexible material. The web is defined, the access assembly, the web folded to enclose the nipple or other access assembly, and folded back to form a liquid compartment. Seals and peelable seals are formed to complete the container and allow access to the nipple for use.
