Cartridge for multi-component masses

1. A cartridge for multi-component masses, comprising a first receiving member ( 22 ; 32 ; 42 ; 52 ) having a receiving space ( 23 ; 33 ; 43 ; 53 ) for at least one component ( 13 ) of a multi-component mass, and at least one other receiving member ( 27 ; 37 ; 47 ; 57 ) arranged parallel to the first receiving member ( 22 ; 32 ; 42 ; 52 ) and having a receiving space ( 28 ; 38 ; 48 ; 58 ) for at least one other component ( 18 ) of the multi-component mass, wherein the receiving space ( 23 ; 33 ; 43 ; 53 ) of the first receiving member ( 22 ; 32 ; 42 ; 52 ) is larger than the receiving space ( 28 ; 38 ; 48 ; 58 ) of the at least one other receiving member ( 27 ; 37 ; 47 ; 57 ), and wherein the first receiving member ( 22 ; 32 ; 42 ; 52 ) has a lower elasticity, at least in a direction transverse to a longitudinal extent (L 1 ; L 2 ) thereof, than the at least one other receiving member ( 27 ; 37 ; 47 ; 57 ), wherein a wall of the at least one other receiving member ( 27 ) has at least one material weakness running along the longitudinal extent (L 1 ) of the first receiving member ( 22 ), and wherein the material weakness comprises a plurality of axial grooves ( 29 ) formed in an inner wall ( 30 ) of the at least one other receiving member ( 27 ) and which open toward the receiving space ( 28 ) of the at least one other receiving member ( 27 ).

2. A cartridge for multi-component masses for use with a conventional ejection device having at least two rods, the cartridge comprising a first receiving member ( 22 ; 32 ; 42 ; 52 ) having a receiving space ( 23 ; 33 ; 43 ; 53 ) for at least one component ( 13 ) of a multi-component mass, and at least one other receiving member ( 27 ; 37 ; 47 ; 57 ) arranged parallel to and in a spaced relationship with the first receiving member ( 22 ; 32 ; 42 ; 52 ), and having a receiving space ( 28 ; 38 ; 48 ; 58 ) for at least one other component ( 18 ) of the multi-component mass, wherein the first and second receiving members have a substantially same longitudinal extent (L 1 ), wherein the receiving space ( 23 ; 33 ; 43 ; 53 ) of the first receiving member ( 22 ; 32 ; 42 ; 52 ) is larger than the receiving space ( 28 ; 38 ; 48 ; 58 ) of the at least one other receiving member ( 27 ; 37 ; 47 ; 57 ), and wherein the first receiving member ( 22 ; 32 ; 42 ; 52 ) has a lower elasticity, at least in a direction transverse to a longitudinal extent (L 1 ; L 2 ) thereof, than the at least one other receiving member ( 27 ; 37 ; 47 ; 57 ).

3. A cartridge according to claim 2 , wherein a wall of the at least one other receiving member ( 27 ) has at least one material weakness running along the longitudinal extent (L 1 ) of the first receiving member ( 22 ).

4. A cartridge according to claim 2 , wherein the at least one other receiving members each has a substantially circular cross-section, and wherein a ratio of the cross-sectional area of the receiving space of the first receiving member and of a cross-sectional area of the receiving space of the at least one other receiving member is three to one.

5. A cartridge according to claim 2 , wherein the first receiving member ( 32 ) has a wall thickness (W 3 ) which is greater than a wall thickness (W 4 ) of the at least one other receiving member ( 37 ).

6. A cartridge according to claim 2 , wherein the first receiving member ( 42 ) and the at least one other receiving member ( 47 ) are formed of different materials.

7. A cartridge according to claim 2 , wherein a material of the first receiving member ( 42 ) has a higher modulus of elasticity than a material of the at least one other receiving member ( 47 ).
