A cartridge, particularly a two-component or multi-component cartridge, with at least one cartridge neck and one outlet opening that is closed with a seal that is integrally connected to the cartridge neck, wherein this connection is sectionally realized at least in sections in the form of a predetermined break point, and wherein the cartridge can be opened by tearing off this connection. In order to allow a simple opening of the seal, it contains at least one cap that is integrally connected to the cartridge neck and at least one tear-off element that is integrally connected to the cap, wherein the connection between the cap and the cartridge neck can be torn off manually by exerting tensile force on the tear-off element.

What is claimed is: 1. A multi-component cartridge comprising: at least one cartridge neck, integrally formed with a cartridge housing and including at least two outlet openings; and a seal integrally formed with the at least one cartridge neck as a unitary element, the seal including a single cap

What is claimed is: 1. A multi-component cartridge comprising: at least one cartridge neck, integrally formed with a cartridge housing and including at least two outlet openings; and a seal integrally formed with the at least one cartridge neck as a unitary element, the seal including a single cap and a single rear-off element that is integrally formed to the single cap and an outer circumference of the at least two outlet openings, such that the single tear-off element secures the single cap over the at least two outlet openings sealing closed the at least two outlet openings, wherein the single tear-off element includes a predetermined break point such that the single cap can be separated from the cartridge neck by tearing off the single tear-off element along the predetermined break point, wherein the single tear-off element can be manually torn off by exerting tensile force upon the tear-off element by one or more fingers of a hand of a user without the use of any auxiliary means, and wherein the at least two outlet openings can be simultaneously exposed by pulling on the single tear-off element. 2. A multi-component cartridge according to claim 1, wherein the single tear-off element consists of a tear-off ring or of a tear-off strap. 3. A multi-component cartridge according to claim 1, wherein the single tear-off clement is formed with the single cap and the cartridge neck in such a way that the single tear-off element does not significantly project beyond the end of the cartridge including the single cap in the longitudinal direction of the cartridge in order to prevent the connection between the single cap and the cartridge neck from becoming unintentionally torn off. 4. A multi-component cartridge according to claim 1, wherein the single tear-off element is arranged adjacent to the cartridge neck. 5. A multi-component cartridge according to claim 1, wherein the cartridge includes an outer cartridge neck and an inner cartridge neck each having an outlet opening, wherein both outlet openings are arranged coaxially to one another, and wherein the seal seals the outlet opening of the outer cartridge neck relative to the surroundings and the outlet opening of the inner cartridge neck relative to the outlet opening of the outer cartridge neck. 6. A multi-component cartridge according to claim 1, wherein the single tear-off element is realized in the form of a tear-off ring that is arranged in a plane that lies perpendicular to the longitudinal axis of the cartridge. 7. A multi-component cartridge according to claim 6 wherein the tear-off ring is essentially arranged at the level of the single cap. 8. A multi-component cartridge according to claim 1, wherein the cartridge contains two outlet openings that are arranged adjacent to one another and separated from one another by a partition wall, wherein the single cap seals both outlet openings relative to the surroundings due to the fact that the single cap is integrally formed with the cartridge neck as well as to the partition wall. 9. A multi-component cartridge according to claim 8, further comprising a second cap separate from the first cap, wherein each cap respectively seals one of the two outlet openings, and by the fact that both caps are connected to one another by means of a tear-off element. 10. A multi-component cartridge according to claim 1, wherein a sealing element suitable for reclosing the cartridge is provided on an upper side of the single cap that faces an interior of the cartridge. 11. A multi-component cartridge according to claim 1, wherein the cap does not significantly project beyond the upper end of the cartridge neck. 12. A multi-component cartridge according to claim 1, wherein the single tear-off element is connected to the single cap by means of a flexible connecting element. 13. A multi-component cartridge according to claim 12, wherein the flexible connecting element is a flexible connecting piece or a series of flexible connecting pieces. 14. A multi-component cartridge according to claim 13, wherein the tear-off element is a tear-off ring connected to the cartridge neck by at least one additional connecting piece, such that the additional connecting piece includes another predetermined break point that is torn off first when a tensile force is excited on the tear-off ring. 15. A multi-component cartridge according to claim 1, wherein the cartridge, which comprises a cartridge housing, the at least one cartridge neck, the single cap, and the single tear-off element, is manufactured as a single piece of material by means of an injection-molding process. 16. The multi-component cartridge according to claim 15, wherein the single piece of material is a single piece of plastic. 17. The multi-component cartridge according to claim 1, wherein the seal is a hermetic seal of the at least two outlet openings relative to each other and relative to outside of the multi-component cartridge. 18. A multi-component cartridge comprising: at least one cartridge neck including an outlet opening; and a seal that is integrally connected to the cartridge neck, such that the seal closes the outlet opening, wherein the integral connection of the seal to the cartridge neck includes a predetermined break point such that the cartridge can be opened by tearing off said connection to facilitate the removal of the seal from the cartridge neck, wherein the seal contains at least one cap that is integrally connected to the cartridge neck and at least one tear-off element that is integrally connected to the cap, such that the connection between the cap and the cartridge neck can be manually torn off by exerting tensile force upon the tear-off element, and wherein at least one additional predetermined break point that is intended for being cut off with a cutting tool is provided in addition to the predetermined break points that can be torn off by means of the tear-off element, wherein the cross section of the outlet openings that results from cutting off the additional predetermined break points is larger than the cross section resulting from tearing off the predetermined break points by means of the tear-off ring.
