Abstract

A device for dispensing a material is disclosed, comprising a reservoir for the material and an outlet channel connectable to the reservoir. The reservoir can comprise a tubular body partially filled with pressurized gas and partially filled with the material to be dispensed. One end of the tubular body can be closed by welding, and the opposite end of the tubular body can be closed by a sealing member extending across at least a portion of the cross-sectional area of ​​the tubular body. The sealing member can be disposed within a sleeve connected to the end of the tubular body opposite the welded end. The sealing member can comprise a pierceable membrane, and the device can further comprise a piercing member. Alternatively, the sealing member can comprise a movable valve, or the sealing member can be removably fixed inside the tubular body, and the device can further comprise an operating member. The tubular body and the piercing member or the operating member can each be movable toward each other.
