(57) Disclosed is a cartridge type ejector comprising a cartridge, a case and a cap, in
which the case and cap can be used repeatedly only by exchanging an empty cartridge
with a full cartridge. An exposure portion for exposing a part of the cartridge is
formed on the case, and the content in the cartridge can be ejected by pressing the
cartridge through this exposure portion. By attaching a pin to the interior of the
cap, the operation of opening the top end of the cartridge can be performed within
the cap. A window for observing this operation is formed on the cap.
