A cartridge ( 11 ) used as a container for a compound that can be ejected by an ejection device, has two receptacles ( 12, 16 ) and a head part ( 21 ), each receptacle ( 12, 16 ) having a receptacle chamber ( 13, 17 ) for components of the compound with the head part ( 21 ) having a base plate ( 22 ) with an outlet opening ( 23 ) for the compound and, at a contact surface ( 24 ) of the base plate ( 22 ), two guide portions ( 25, 26 ) for joining to an end ( 14, 18 ) of the corresponding receptacle ( 12, 16 ), a guide element for the receptacle ( 16 ) arranged adjacent to the guide portion ( 26 ) at the contact surface ( 24 ) of the head part ( 21 ).
1. A cartridge used as container for a compound that can be ejected by an ejection device, the cartridge comprising at least one receptacle ( 12 , 16 , 36 ; 42 ) having a receiving chamber ( 13 , 17 , 37 ) for the compound; a head part ( 21 ; 51 ) including a base plate ( 22 ) with an outlet opening ( 23 ) for the compound, a contact surface ( 24 ; 54 ) and at least one guide portion ( 25 , 26 ; 55 ) provided at the contact surface ( 24 ; 54 ) for joining to an end ( 14 , 18 , 38 ; 44 ) of the at least one receptacle ( 12 , 16 , 36 ; 42 ); and at least one guide element for the at least one receptacle ( 16 , 36 ; 42 ) arranged adjacent to the guide portion ( 26 ; 55 ) at the contact surface ( 24 ; 54 ) of the head part ( 21 ; 51 ),
wherein the at least one receptacle 12 , 16 , 36 ; 42 ) has a wall thickness (W 1 , W 2 ) which extends from a side of the receptacle ( 12 , 16 , 36 ; 42 ) facing the receptacle chamber ( 13 , 17 , 37 ) to a side of the receptacle ( 12 , 16 , 36 ; 42 ) directed radially outwardly, and the at least guide element is formed as a guide projection ( 27 ) protruding from the contact surface ( 24 ) of the head part ( 21 ) and provided at a distance (G) from the guide portion ( 26 ) of the head part ( 21 ) corresponding to 0.9-times to 1.1-times the wall thickness (W 2 ) of the receptacle ( 16 ).
2. A cartridge according to claim 1 , wherein a plurality of guide portions ( 25 , 26 ; 55 ) are provided at the head part ( 21 ; 51 ) for guiding the respective ends ( 14 , 28 ; 44 ) of a plurality of receptacles ( 12 , 16 ; 42 ), each for a component of a multi-component compound, wherein the at least one guide element is provided at least adjacent to one of the guide portions ( 26 ; 55 ).
3. A cartridge according to claim 1 , wherein the at least one guide portion ( 25 , 26 ; 55 ) is a circumferential wall portion projecting from the contact surface ( 24 ; 54 ) of the head part ( 21 ; 51 ), and the at least one guide element is arranged on the inner side of the wall portion.
