Abstract
Abstract The pasty components of a multicomponent material are first contained in separate tubular portions (11,12) which, prior to the mixing operation, are assembled together to form a cartridge (10) having a cylindrical inner wall and in which a mixing means is accomodated which consists of a rotationgly driven disk (21) and of a relatively stationary disk (18). Via a rod (29) projecting out of the cartridge (10), disk (21) is drivable by a rotating tool. By reciprocation of the rotating tool, both disks (18 and 21) are moved axially to the cartridge (10). Upon the mixing performed by displacing and redistributing of the materials, the piston (13) is advanced in order to squeeze the mixture out of the cartridge.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
A mixing device for pasty multicomponent materials comprising a tubular cartridge including first and second tubular portions each adapted to house an individual pasty material, mixing means axially displaceable in said tubular cartridge by a rod for admixing the individual pasty materials, said mixing means being a pair of relatively rotatable disks, means for preventing rotation of a first of said disks, aperture means in said disks, a second of said disks being connected to and rotatable by said rod, a piston in said tubular cartridge movable from a first position remote from an outlet end of said tubular cartridge toward a second position adjacent said outlet end whereby admixed pasty material passes through said disk aperture means incident to exiting said tubular cartridge at said outlet end, and said piston is mounted in sliding relationship to said rod.
Claim 2
Dependent Claim
139 words
A mixing device for pasty multicomponent materials comprising a tubular cartridge including first and second tubular portions each adapted to house an individual pasty material, mixing means axially displaceable in said tubular cartridge by a rod for admixing the individual pasty materials, said mixing means being a pair of relatively rotatable disks, means for preventing rotation of a first of said disks, aperture means in said disks, a second of said disks being connected to and rotatable by said rod, a piston in said tubular cartridge movable from a first position remote from an outlet end of said tubular cartridge toward a second position adjacent said outlet end whereby admixed pasty material passes through said disk aperture means incident to exiting said tubular cartridge at said outlet end, and said piston is mounted in sliding relationship to said rod.
Claim 3
Dependent Claim
38 words
The mixing device as defined in claim 1 including stop means at another end of said tubular cartridge remote from the outlet end thereof for stopping movement of said piston when said piston moves toward said first position.
Claim 4
Dependent Claim
20 words
The mixing device as defined in claim 1 including means for lockingly coupling said first and second tubular portions together.
Claim 5
Dependent Claim
39 words
The mixing device as defined in claim 1 including detachable cover means for closing one end of each of said tubular portions prior to forming the tubular cartridge therefrom thereby containing the individual pasty material in each tubular portion.
Claim 6
Dependent Claim
25 words
The mixing device as defined in claim 1 wherein said first and second tubular portions are at least in partial telescopic relationship to each other.
Claim 7
Dependent Claim
30 words
The mixing device as defined in claim 1 wherein said rod is housed generally entirely within said tubular cartridge when said disks are located adjacent said tubular cartridge outlet end.
Claim 8
Dependent Claim
27 words
The mixing device as defined in claim 1 wherein said rotation preventing means is defined by surfaces of said tubular cartridge and first disk in frictional engagement.
Claim 9
Dependent Claim
45 words
The mixing device as defined in claim 1 including another nonrotating disk adjacent said first nonrotating disk, a circumferential wall connecting said another and first nonrotating disks together, and said rotating disk is housed by said first and another nonrotating disk and said circumferential wall.
Claim 10
Dependent Claim
29 words
The mixing device as defined in claim 1 including a tube connected to said nonrotating said rod is housed in said tube and said tube passes through said piston.
Claim 11
Dependent Claim
16 words
The mixing device as defined in claim 1 wherein one of said disks is a propeller.
