ABSTRACT:
An ampoule for containing a specified amount of liquid inside to be used for a liquid atomizer has a tubular main body having an open front part including an outlet at one end and an open back part at an opposite end. A piston is inserted into the main body from the open front part in an airtight manner and is slidable axially inside the main body. Another piston is inserted into the main body from the open back part in an airtight manner so as to be slidable axially inside the main body. The two pistons form a reservoir in between for storing a liquid. The forwardly located piston has a weakened part on the side that faces the reservoir. As a sharp member extending from the other piston penetrates this weakened, the reservoir and the outlet become connected and the liquid inside the reservoir is discharged.
