Abstract

A head part ( 11 ) for a multi-chamber tube bag ( 1 ) with a multi-component mass which can be pressed out, having a main chamber ( 2 ) for a first component and two secondary chambers ( 3, 4 ) for two other components, has a disk-shaped contact surface ( 12 ) for the multi-chamber tube bag ( 1 ) surrounding a press-out opening ( 13 ). At the contact surface ( 12 ), a plurality of raised portions ( 14 ) project toward the multi-chamber tube bag ( 1 ) and are provided at the head part ( 11 ) for narrowing the outlet regions ( 5, 6 ) of the two secondary chambers ( 3, 4 ) of the multi-chamber tube bag ( 1 ) when the multi-chamber tube bag ( 1 ) bears against the contact surface ( 12 ).

Claims (10)

1. Head part for a multi-chamber tube bag ( 1 ; 35 ; 55 ) containing a multi-component mass which can be pressed out of said bag, said bag having a main chamber ( 2 ) arranged for holding a first component and at least one secondary chamber ( 3 , 4 ) at least partially laterally enclosing the main chamber for another component to be mixed with the first component, the head part ( 11 ; 32 ; 42 , 52 ; 62 ) comprising:

a substantially flat contact surface ( 12 ; 22 ) facing a discharge end surface of said multi-chamber tube bag, said contact surface surrounds a tubular press-out opening ( 13 ; 23 ) extending outwardly away from said tube bag ( 1 ; 35 ; 55 ) and aligned with the main chamber, said contact surface ( 12 ; 22 ) having at least one raised part ( 14 ; 24 ; 36 ; 56 ) arranged in the direction of the discharge end surface of the multi-chamber tube bag ( 1 ; 35 ; 55 ), with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) in contact with the contact surface of the head part simultaneous with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) of the contact surface ( 12 ; 22 ) being aligned to the multi-chamber tube bag ( 1 ; 35 ; 55 ), and with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) extending therefrom opposite into contact with said secondary chamber to said press-out opening for narrowing an outlet opening of at least one said secondary chamber ( 3 ; 4 ) into said press-out opening ( 13 ; 23 ) and for throttling the flow from the secondary chamber;

wherein said head part ( 52 , 62 ) is a component part of a cartridge for laterally enclosing said multi-chamber tube bag ( 55 ); and

wherein said head part ( 62 ) is formed as a base of said cartridge for the said multi-chamber tube bag ( 55 ).

2. A multi-chamber tube bag ( 1 ; 35 ; 55 ) containing a multi-component mass which can be pressed out of the bag, multi-chamber tube bag ( 1 ; 35 ; 55 ) comprising:

a main chamber ( 2 ) arranged for holding a first component;

at least one secondary chamber ( 3 , 4 ) at least partially laterally enclosing the main chamber ( 2 ) for another component to be mixed with the first component; and

a head part ( 11 ; 32 ; 42 , 52 ; 62 ) having a substantially flat contact surface ( 12 ; 22 ) facing a discharge end surface of the multi-chamber tube bag, the contact surface surrounds a tubular press-out opening ( 13 ; 23 ) extending outwardly away from the tube bag ( 1 ; 35 ; 55 ) and aligned with the main chamber, the contact surface ( 12 ; 22 ) having at least one raised part ( 14 ; 24 ; 36 ; 56 ) arranged in the direction of the discharge end surface of the multi-chamber tube bag ( 1 ; 35 ; 55 ), with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) in contact with the contact surface of the head part simultaneous with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) of the contact surface ( 12 ; 22 ) being aligned to the multi-chamber tube bag ( 1 ; 35 ; 55 ), and with the at least one raised part ( 14 ; 24 ; 36 ; 56 ) extending therefrom opposite into contact with the secondary chamber to the press-out opening for narrowing an outlet opening of at least one the secondary chamber ( 3 ; 4 ) into the press-out opening ( 13 ; 23 ) and for throttling the flow from the secondary chamber;

wherein the head part ( 52 , 62 ) is a component part of a cartridge for laterally enclosing the multi-chamber tube bag ( 55 ); and

wherein the head part ( 62 ) is formed as a base of the cartridge for the multi-chamber tube bag ( 55 ).
