ABSTRACT:
A medication delivery device having a reduced weight due to the configuration of the end terminal of the pleated bellows reservoir. The end terminal includes an indented portion which is sized such that when the reservoir is in the compressed/empty position there is substantially no separation between the indented portion and the base portion of the reservoir. This construction allows the reservoir to be almost completely emptied of medication when the reservoir is collapsed but does so in a manner which does not add to the weight of the device.
