ABSTRACT OF THE DISCLOSURE
A reservoir for containing liquid medicaments is
disclosed. The reservoir includes a relatively stiff elon-
gate channel portion which has an inlet at one end and outlet
at the opposite end and which is open at one side. The
channel portion defines a side of the reservoir. A pair of
walls are integrally coupled to the channel portion and
extend away from said portion in generally parallel rela-
tionship with the open side of the channel portion between
the walls. The walls are sealed together around peripheral
regions thereof and define with the channel portion a liquid-
tight internal space which communicates with the inlet and
outlet. The walls are resiliently flexible so as to be
capable of bulging outwardly to accommodate liquid entering
through the inlet, and collapsing inwardly towards one
another from said peripheral regions towards said channel
portion as medicament is withdrawn through the outlet.
