Abstract

An application device includes an applicator unit ( 12 ) which is provided with an applicator ( 14 ) and which has a cylindrical peg ( 18 ) on the side facing away from the applicator ( 14 ), which is penetrated by a cross channel ( 26 ), from which an axial channel ( 28 ) branches off, which leads to the applicator ( 14 ), in which a shiftable reservoir ( 30 ) is arranged. The reservoir ( 30 ) has an annular lip seal ( 38 ) which interacts as a seal with the cylindrical peg ( 18 ). The activation of the application device occurs by shifting the reservoir ( 30 ) on the cylindrical peg ( 18 ) in the direction of the applicator ( 14 ). The reservoir ( 30 ) has a foldable, bag-like, deformable receiver section ( 34 ), so that when a flow connection between the application device and the cross channel ( 26 ) and the receiver section ( 34 ) is established in the activation position, the flowable substance is discharged via the applicator ( 14 ) through manual deformation of the bag-like receiver section ( 34 ).

Claims (25)

1. An application device for a flowable substance, compnsing

an applicator unit ( 12 ) which is provided with an applicator ( 14 ) and which has a cylindrical peg ( 18 ) on a side facing away from the applicator ( 14 ), which is penetrated by a cross channel ( 26 ), from which an axial channel ( 28 ) branches off, which leads to the applicator ( 14 ), on said applicator unit ( 12 ), a shiftable reservoir ( 30 ) being arranged, which has an annular lip seal ( 38 ) which acts as a seal together with the cylindrical peg ( 18 ), in which activation of the application device occurs by shifting the reservoir ( 30 ) on the cylindrical peg ( 18 ) toward the applicator ( 14 ) to an activation position in order to open a flow connection between the reservoir ( 30 ) and the cross channel ( 26 ), wherein the reservoir ( 30 ) has a foldable, bag-like, deformable receiver section ( 34 ), so that when a flow connection between the application device and the cross channel ( 26 ) and the receiver section ( 34 ) is established in the activation position, the flowable substance is discharged via the applicator ( 14 ) through manual deformation of the foldable, bag-like receiver section ( 34 ).

2. The application device as in claim 1 , wherein the bag-like receiver section ( 34 ) is created by two film cut-outs ( 40 , 42 ) which are sealed together along their edges.

3. The application device as in claim 1 , wherein the reservoir ( 30 ) has a rigid guide insert ( 44 ) in which a bore ( 46 ) for guiding the peg ( 18 ) of the applicator unit ( 12 ) is arranged.

4. The application device as in claim 3 , wherein the guide insert ( 44 ) is sealed with a bag-like receiver section ( 34 ).

5. The application device as in claim 3 , wherein the guide insert ( 44 ) essentially has converging wedge-shaped edges.

6. The application device as in claim 1 , characterized by a detent mechanism which secures the peg in the activation position.

7. The application device as in claim 6 , wherein the detent mechanism comprises a peg which can be screwed into an annular groove of the reservoir in order to secure the activation position.

8. The application device as in claim 1 , wherein the cylindrical peg ( 18 ) has at least one annular groove which interacts with the lip seal ( 38 ) and defines a de-activation position and/or an activation position of the reservoir.

9. An application device for a flowable substance, comprising an applicator unit ( 12 ) which is provided with an applicator ( 14 ) and which has a cylindrical peg ( 18 ), which is penetrated by a cross channel ( 26 ), from which an axial channel ( 28 ) branches off, which leads to the applicator ( 14 ), on said applicator unit ( 12 ), a shiftable reservoir ( 30 ) being arranged, which has an annular lip seal ( 38 ) which interacts as a seal with the cylindrical peg ( 18 ), in which activation of the application device occurs by shifting the reservoir ( 30 ) on the cylindrical peg ( 18 ) toward the applicator ( 14 ) to an activation position in order to open a flow connection between the reservoir ( 30 ) and the cross channel ( 26 ), wherein the reservoir ( 30 ) has a receiver section ( 34 ) provided with a pump device, so that when a flow connection between the application unit and the cross channel ( 26 ) and the receiver section ( 34 ) is established in the activation position, the flowable substance is discharged via the applicator ( 14 ) by actuation of the pump device.

10. The application device as in claim 9 , wherein the reservoir ( 30 ) has a rigid guide insert ( 44 ) in which a bore ( 46 ) for guiding the peg ( 18 ) of the applicator unit ( 12 ) is arranged.

11. The application device as in claim 10 , wherein the guide insert ( 44 ) is sealed with a bag-like receiver section ( 34 ).

12. The application device as in claim 10 , wherein the guide insert ( 44 ) essentially has converging wedge-shaped edges.

13. The application device as in claim 9 , characterized by a detent mechanism which secures the peg in the activation position.

14. The application device as in claim 13 , wherein the detent mechanism comprises a peg which can be screwed into an annular groove of the reservoir in order to secure the activation position.

15. The application device as in claim 9 , wherein the cylindrical peg ( 18 ) has at least one annular groove which interacts with the lip seal ( 38 ) and defines a de-activation position and/or an activation position of the reservoir.

16. An application device for a flowable substance, said device comprising

an applicator unit defining a reservoir for holding a flowable substance, said reservoir having a foldable, bag-like receiver section;

a bore in fluid communication with said receiver section, said bore including an annular seal;

a peg slidably received in said bore and engaging said annular seal, said peg including a cross channel formed at one end received through said bore and an axial channel branching off from said cross channel; and

an applicator disposed at a second end of said peg and in fluid communication with said axial channel, wherein activation of the application device occurs by sliding said peg into the reservoir to an activation position in order to open a flow connection between the reservoir and the cross channel and the flowable substance is discharged via the applicator through manual deformation of the foldable, bag-like receiver section.

17. The application device as in claim 16 , wherein the foldable, bag-like receiver section is created by two film cut-outs which are sealed together along their edges.

18. The application device as in claim 16 , wherein the reservoir has a rigid guide insert in which a bore for guiding the peg of the applicator unit is arranged.

19. The application device as in claim 16 , characterized by a detent mechanism which secures the peg in the activation position.

20. The application device as in claim 16 , wherein the peg has at least one annular groove which interacts with the annular seal and defines a de-activation position and/or an activation position of the reservoir.
