Abstract
Disclosed herein is a device for dispensing viscous materials, in which an air tight container is provided with a first pipe connecting the inside thereof to a nozzle for supplying the material to a consumption area, and with a second pipe for connecting the inside thereof to a line connected, with the interposition of an air flow regulator, to a source of compressed air. Means are provided for fixing, inside the container, a pre-prepared cartridge of viscous material, placed with a low aperture in communication with the first pipe and communicating via an upper aperture with the second pipe.
Claims3
A device for dispensing viscous material, comprising:
- an airtight container;
- a first pipe connecting the inside of said airtight container to a nozzle for supplying the viscous material to a consumption area;
- a second pipe for connecting the inside of said airtight container to a line connected, with the interposition of an air flow regulator, to a source of compressed air;
- means for fixing, inside said container, a cartridge containing viscous material said cartridge having a low aperature at the bottom of said cartridge and an upper aperature located above the uppermost level of said viscous material, said low aperature being adjacent and communicating with the inlet of said first pipe said upper aperature being in communication with said second pipe, whereby, air from said second pipe forcing said viscous material through said nozzle and exiting through said nozzle when the supply of viscous material has been exhausted;
- a flow control element interposed in said line and connected to an alarm device so as to set such alarm in operation upon sensing that air is passing directly from the said source to the said nozzle because said cartridge has become depleted of said viscous material.
