A device for dispensing a sealant or other material. The device has a housing containing a chamber with a dispensing orifice at a first end and an actuation opening at a second end opposite the first end. The chamber contains a mixing paddle which can be rotated and translated back and forth inside the chamber; a piston; and a membrane with an open end in fluid communication with the actuation opening. The membrane is arranged such that it can be inflated by injecting fluid into its open end via the actuation opening, inflation of the membrane causing it to press against the piston and push the piston towards the mixing paddle and the dispensing orifice which in turn forces the material past the mixing paddle and out of the dispensing orifice. |
