摘要：
The invention relates to an applicator system (35) with at least one exchangeable cartridge (1), which consists at least of a mass container (2), which in the new state contains a mass supply, and an applicator unit (3), which in any case projects with one end into the area of the mass supply and with its other end forms a closure of the recipient, which is the mass container (2), and a sleeve (20), in which the exchangeable cartridge (1) can be fixed, and a cap (23), which can be fixed to the sleeve (20) in order to close the removal side of the sleeve (20) from which the applicator unit (3) can be taken, characterized in that the applicator unit (3) provides, at the end with which it forms the closure of the mass container (2), a coupling element (4) which is designed and positioned such that it enters into a connection with a counter-coupling element (36) if the exchangeable cartridge (1) is completely inserted into the sleeve (20) while the sleeve (20) is closed on its removal side with the cap (23).

CLAIMS
1. Refillable applicator system (35) with at least one exchangeable cartridge (1) , which consists at least of a mass container (2) , which in the new state contains a mass supply, and an applicator unit (3) , which in any case projects with one end into the area of the mass supply and with its other end forms a closure of the recipient, which is the mass container (2) , and a sleeve (20) , in which the exchangeable cartridge (1) can be fixed, and a cap (23) , which can be fixed to the sleeve (20) in order to close the removal side of the sleeve (20) from which the applicator unit (3) can be taken, characterized in that the applicator unit (3) provides, at the end with which it forms the closure of the mass container (2) , a coupling element (4) which is designed and positioned such that it enters into a connection with a counter-coupling element (36) if the exchangeable cartridge (1) is completely inserted into the sleeve (20) while the sleeve (20) is closed on its removal side with the cap (23) .
2. Refillable applicator system (35) according to claim 1, characterized in that the cap (23) has an ejector (37) operatively connected to the rest of the cap (23) such that the coupling element (4) and the counter-coupling element (36) can again be disengaged by imparting relative movement to the ejector (37) with respect to the rest of the cap (23) .
3. Refillable applicator system (35) according to claim 2, characterized in that the ejector (37) is a press piston (33) , preferably in the form of a threaded rod, that can be
moved, preferably rotated, out of the cap (23) in the direction toward the exchangeable cartridge (1) .
4. Refillable applicator system (35) according to claim 3, characterized in that the cap (23) comprises a cap base body (26) and a rotatably mounted cap top (27) having a nut thread, preferably in the form of a steep thread sliding back to its initial position under external pressure, which advances or retracts the press piston (33) , preferably in the form of a threaded rod, upon rotation of said cap top (27) .
5. Refillable applicator system (35) according to one of the preceding claims, characterized in that the counter-coupling element (36) is a tube section (30) of the cap (23) , acting as a tubular gripper, which is slotted once or several times and which, in the coupled state, engages over the coupling element (4) and is latched thereto.
6. Refillable applicator system (35) according to claim 5, characterized in that the press piston (33) , preferably in the form of a threaded rod, can be advanced inside the tube section (30) to disengage the coupling from the latched connection with the tube section (30) .
7. Refillable applicator system (35) according to one of the preceding claims, characterized in that the sleeve (20) has an insertion and ejection opening for the exchangeable cartridge (1) on its end face facing away from the cap (23) .
8. Refillable applicator system (35) according to one of the preceding claims, characterized in that the exchangeable cartridge (1) has an external thread and/or at least one
latching element (18, 19) by means of which it can be anchored to the sleeve (20) in its position of use.
9. Refillable applicator system (35) according to one of the preceding claims, characterized in that the anchoring of the exchangeable cartridge (1) to the sleeve (20) , the coupling element (4) and the counter-coupling element (36) as well as the ejector (37) are designed in such a way that, when the ejector (37) is fully actuated as intended, not only the coupling element (4) and the counter-coupling element (36) are disengaged from one another but also the exchangeable cartridge (1) is pushed out of the sleeve (20) at least a little way.
10. Refillable applicator system (35) according to one of the preceding claims, characterized in that the ejector (37) is a press piston (33) with at least one actuator and at least one spring element, whereby the press piston (33) can be moved in the direction towards the exchangeable cartridge (1) by pressing the actuator.
11. Refillable applicator system (35) according to one of the preceding claims, characterized in that the at least one spring element stands in contact with the cap base body (26) and when moved further into the direction towards the exchangeable cartridge (1) unfolds a spring action, through which the press piston (33) is pushed back into the direction away from the exchangeable cartridge (1) .
12. Refillable applicator system (35) according to one of the preceding claims, characterized in that the spring element at
least partially encloses the press piston (33) .
13. Refillable applicator system (35) according to one of the preceding claims, characterized in that the spring element comprises spring windings spiraling around a center and/or spring rings (39) .
14. Refillable applicator system (35) according to the preceding claim, characterized in that the spring rings (39) are circumferential rings lying one below the other and each having at least two recesses, the recesses of two directly adjacent rings being offset from one another.
15. Refillable applicator system (35) according to one of the preceding claims, characterized in that the actuator is a press button (38) , which at least partially protrudes from the cap top (27) and/or is accessible to the user so that it can be pushed downwards by the user.
