Container for liquid detergent and method for the metered dispensing of detergent from the container

1. A container for liquid washing agent, comprising:

a main container body for receiving the washing agent;

an opening for dispensing the washing agent;

a first standing base that is arranged opposite the opening and defines a filling position of the container;

a second standing base that is arranged beside the first standing base and defines a storage position of the container;

a grip region that extends towards the opening from a side of the first standing base remote from the second standing base; and

a rolling surface that is arranged opposite the grip region and extends substantially from the second standing base as far as the opening wherein the rolling surface is substantially curved and comprises a plurality of ribs positioned such that advancing the container from any rib to a next rib dispenses a fixed amount of fluid from the container,

wherein the grip region comprises a portion which is arranged above the second standing base when the container is standing on the second standing base in the storage position.

2. The container of claim 1 , wherein the first standing base defines a first standing plane and the second standing base defines a second standing plane, and an angle (α) between the first standing plane and the second standing plane is 20 to 40 degrees.

3. The container of claim 1 , wherein the first standing base and the second standing base are directly adjacent and form a shared edge.

4. The container of claim 1 , wherein the second standing base comprises a concave portion that corresponds to a convex portion on a side of the main container body opposite the second standing base.

5. The container of claim 1 , further comprising a handle that is pivotally articulated to the main container body and attached to the grip region.

6. The container of claim 1 , wherein a loop of the handle is formed in one piece with the main container body by means of a film hinge.

7. The container of claim 1 , wherein the grip region is an integral part of the main container body.

8. The container of claim 1 , wherein the main container body has a first grip indentation on one side wall and a second grip indentation on another side wall to form the grip region.

9. The container of claim 1 , wherein the rolling surface comprises a stop providing roll-away protection.

10. The container of claim 1 , wherein the rolling surface comprises at least 19 ribs.

11. The container of claim 1 , wherein the rolling surface comprises 51 to 151 ribs.

12. A container for dispensing metered amounts of liquid, the container comprising:

a reservoir for holding liquid;

an opening in the reservoir for dispensing liquid from the reservoir;

a handle for gripping the container;

a base on the bottom of the container to allow the container to stand unsupported;

a rolling surface extending from the base towards the opening, the rolling surface comprising at least 19 protrusions extending across a face of the rolling surface orthogonal to a direction of rolling of the rolling surface, the protrusions parallel to each other and spaced such that advancing from any protrusion to the next, adjacent protrusion by rolling the container on the rolling surfaces dispenses a same amount of liquid from the opening.

13. The container of claim 12 , wherein the rolling surface comprises at least 51 protrusions.

14. The container of claim 12 , further comprising a second base allowing the container to stand in a second orientation, the second base having a concave shape.

15. A method for dispensing liquid from a container in a metered manner, comprising:

providing a container containing liquid, the container comprising: a rolling surface comprising: a first protrusion, a second protrusion, and a third protrusion;

wherein rolling the container from the first protrusion to the second protrusion dispenses a first fixed volume of liquid from the container and wherein rolling the container from the second protrusion to the third protrusion dispenses a second, equal fixed volume of liquid from the container.

16. The method of claim 15 , wherein the rolling surface comprises at least 19 protrusions.

17. The method of claim 15 , wherein the rolling surface comprises 51 to 151 protrusions.
