Abstract

The invention relates to a device for applying flowing media to a surface. Said device comprises a container (1) for the media with at least one opening (2, 3) which is located above the surface and can be deaerated and a mopping or applicator device (5) which is attached to a handle (4). In addition, the device has a flow-regulating hose (6) which can be shut off, for conveying the media from the container (1) by force of gravity to an outlet on the mopping or applicator device (5). In addition, the device has a portable unit which is worn on the back, comprising supporting and fixing straps (8) and a mounting plate (9) which is fitted to said unit and which has a rapid-action coupling device. The container has (1) a resealable exit opening at one end (2) with a connecting sleeve and a resealable fill opening (3) at the opposite end, in addition to a hose adapter (11) which can be connected to the connecting sleeve of the exit opening (2). Said adapter has a shut-off device (12) and a rapid-action coupling (13) for the hose with a drip-protection unit.

Claims

1. Device for applying a flowable medium to a surface, comprising

an aeratable container, which is arranged above the surface, for the medium, with at least one opening,

a wiping or applying device mounted at a handle,

a duct, which can be regulated for shutting-off or allowing throughflow, for conducting the medium from the container to an outlet on or at the wiping or applying device, and

equipment, which can be worn on the back, with supporting and fixing straps and a mounting plate, which is attached thereto, for the container,

wherein the container has at the lower end a resealable outlet opening with a connecting piece, wherein

the conducting of the medium from the conveyor is produced by gravitational force,

the container has a hose adapter, which is connectible to the connecting piece of the outlet opening, with a hose quick-action coupling with a drip protection device, and

the hose adapter has an aerating element connected with a pipe, which is led outside the container to above the uppermost point thereof and the upper end of which, which is open to the atmosphere, is secured by a one-way element against outflow.

2. Device according to claim 1, wherein the mounting plate has a quick-action coupling device for the container and the container has coupling element matched to the quick-action coupling device of the mounting plate.

3. Device according to claim 1, wherein a cask receiver is provided, which comprises coupling elements matched to the quick-action coupling device of the mounting plate.

4. Device according to claim 1, wherein the hose adapter comprises a closure system matched to the connecting piece.

5. Device according to claim 1, wherein a resealable filling opening, which has a closure cover, is provided at the upper end of the container and the shape and/or the size of the filling opening is suitable for pouring in the flowable medium without a funnel or similar aid.

6. Device according to one of claim 2, wherein that the quick-action coupling device comprises a hook-in element and a clamping element and that the coupling elements of the cask receiver or of the container comprise a clip element matched to the hook-in element and plug elements matched to the clamping elements.

7. Device according to claim 1, wherein the container comprises a filling state marking and a specific connecting device for refill cartridges or other dosage containers.

8. Device according to claim 7, wherein the connecting device is arranged in the closure cover of the filling opening.

9. Device according to claim 1, wherein the outlet of the duct is arranged at a predetermined spacing above the surface.

10. Device according to claim 1, wherein a metering valve for throughflow regulation is arranged on or at the wiping or applying device between the hose quick-action coupling and the outlet of the duct.

11. Device according to claim 1, wherein the closure system comprises at least one of a screw closure and a bayonet closure.
