Abstract
Disclosed herein are various embodiments providing an expandable, flexible reservoir for use in a wearable drug delivery device. The reservoir comprises a flexible enclosure made with plastic film which incorporates pleats forming the side walls thereof to increase the volume efficiency and to avoid a 'pillowing' effect when the reservoir is filled. The pleats may be formed at non-right angles with respect to each other such as to form a curved side walls for the reservoir. In variations of the invention, various methods are disclosed for maintaining a vacuum with the reservoir during its shelf life.
