The multiple component metering and relative proportioning device, in particular a two-component co-axial device, comprises a cartridge (1) wherein at least one inner package assembly (3) containing one component is lodged within an outer package assembly (2) containing another component. The package assemblies (2, 3) are collapsible and are located in a reusable rigid housing (4), each package assembly having an individual outlet (8, 11), all individual outlets being joined in a common outlet piece (10). The package assemblies are sealed at their other end where a re-usable piston (23) is slidingly lodged within the rigid housing for collapsing the package assemblies and dispensing their content. Such a device allows an efficient disposal of the collapsed package assemblies and of the front outlet piece, and rear pieces in a compact form, whereas the other parts are re-usable, thus maintaining a high reliability, user friendliness and cost effectiveness of the device.
A multiple component metering and relative proportioning device, comprising a collapsible cartridge, a first receptacle containing a first component, and a second receptacle containing a second component, wherein the receptacles are package assemblies which are collapsible and located in a housing, each package assembly comprising a package tube and having an individual outlet at an outlet end, all individual outlets being joined in a common cartridge front piece, the package assemblies being sealed at an inlet end where a piston is disposed in the housing for progressively collapsing the package assemblies during a stroke of the piston, the contents of the package assemblies being discharged through the outlets in predetermined relative proportions;
A device according to 1, wherein the piston comprises venting means through its bottom for allowing air enclosed in the housing to escape.
A multiple component metering and relative proportioning device, comprising a collapsible cartridge, a first receptacle containing a first component, and a second receptacle containing a second component, wherein the receptacles are package assemblies which are collapsible and located in a housing, each package assembly comprising a package tube and having an individual outlet at an outlet end, all individual outlets being joined in a common cartridge front piece, the package assemblies being sealed at an inlet end where a piston is disposed in the housing for progressively collapsing the package assemblies during a stroke of the piston, the contents of the package assemblies being discharged through the outlets in predetermined relative proportions;
A multiple component metering and relative proportioning device, comprising a collapsible cartridge, wherein at least one receptacle containing one component is located within a second receptacle containing another component, wherein the receptacles are package assemblies which are collapsible and located in a housing, each package assembly comprising a package tube and having an individual outlet at an outlet end, all individual outlets being joined in a common cartridge front piece, the package assemblies being sealed at an inlet end where a piston is disposed in the housing for progressively collapsing the package assemblies during a stroke of the piston, the contents of the package assemblies being discharged through the outlets in predetermined relative proportions;
