Arrangement for applying a liquid
View Patent ↗The invention relates to a device for applying a fluid, comprising an application container ( 12 ) limiting a receiving space ( 34 ), the application container being equipped at a first end ( 14 ) with an application unit ( 16 ), and being connected via a valve unit ( 20 ) at a second end to a reservoir container ( 22 ) having a reservoir space ( 38 ), the reservoir container being embodied of a sleeve which is guided at a plunger-like cylindrical body ( 26 ) of the valve unit ( 20 ) via an annular collar ( 24 ) that has a lateral channel ( 30 ), which is connected to an axial channel ( 32 ), which leads to the receiving space ( 34 ) of the application container ( 12 ). The reservoir container ( 22 ) is detachably embodied as opposed to the application container ( 21 ) such that in a closed position of the reservoir container ( 22 ) a fluid flow between the reservoir space ( 38 ) of the receiving space ( 34 ) is blocked, and that in an activating position of the reservoir container ( 22 ) the reservoir space ( 38 ) and the receiving space ( 34 ) are connected via the lateral channel ( 30 ) and the axial channel ( 32 ).
1. A device for applying a fluid, said device comprising:
a tube-like application container having a receiving space for mixing fluid components, said container extending between a first end and a second end;
an application unit disposed at said first end downstream of said receiving space;
a valve unit upstream of said receiving space and having a valve body disposed at said second end and in fluid communication with said receiving space, said valve body including a plunger-like cylindrical body extending away from said application unit; and
a reservoir container having at least one reservoir space connected to said valve unit, the reservoir container including a sleeve closed at a side facing away from the application unit, and which is guided at the plunger-like cylindrical body of the valve unit via an annular collar that protrudes at least radially from an inner wall of the sleeve, the cylindrical body having a lateral channel that is arranged in the area of the sleeve, and that is connected to an axial channel, which leads to the receiving space of the application container through said valve body, wherein the reservoir container is movable between a closed position and an activating position, such that in the closed position of the reservoir container a fluid flow between the reservoir space of the reservoir container and the receiving space of the application container is blocked by said annular collar, and that in the activating position of the reservoir container the reservoir space and the receiving space are connected via the lateral channel and the axial channel of the valve unit, wherein the application container is made of an elastic, deformable soft plastic material, and the plunger-like cylindrical body of the valve unit is limited by an annular recess of the valve unit, into which the reservoir container dips upon the displacement in the activating position.
2. The device according to claim 1 , wherein an actuating flange is arranged in the area of the second end of the application container.
3. The device according to claim 1 , wherein the plunger-like cylindrical body has a length essentially corresponding to the axial extension of the reservoir container.
4. The device according to claim 1 , wherein the definition of the closing position of the reservoir container the annular collar cooperates with an annular groove, which is arranged upstream of the lateral channel at the circumference of the cylindrical body.
5. The device according to claim 1 , wherein the application device comprises a brush.
6. The device according to claim 1 , wherein the application device comprises a nozzle.
7. The device according to claim 1 , wherein the application device comprises a sponge-like application device.
8. The device according to claim 1 , wherein the receiving space of the application container receives a first mixing component, and the reservoir space of the reservoir container receives a second mixing component of a two-component system, which is mixed with the first mixing component upon a displacement of the reservoir container in the activated position into the receiving space of the application container.
9. The device according to claim 1 , wherein the reservoir container has several reservoir spaces, which are separated from each other by means of at least one moveable partition wall.
