Abstract

A container including a thermoformed tub made of a plastics material and including at least one dosing unit located in the tub interior, which dosing unit includes at least one active ingredient and a water-soluble casing for the active ingredient, the tub having a base and a tub wall that extends from the base. The tub wall has a plurality of projections that are oriented from a datum plane of the tub wall towards the tub interior, a distance between adjacent projections being less than a length and less than a width of the dosing unit. Preferably, the projections have a plurality of parallel ridges.

First claim

What is claimed is:

1. A container comprising a thermoformed tub made of a plastics material, said tub having a tub interior; at least one dosing unit having a length and a width arranged in said tub interior, wherein the dosing unit comprises at least one active ingredient enclosed in a water-soluble casing, the tub comprising a base and a tub wall that extends from the base, wherein the tub wall comprises a plurality of projections that are oriented from a datum plane of the tub wall towards the tub interior, the tub wall having a distance between adjacent projections wherein said distance is less than said length and less than said width of the dosing unit.

2. The container according to claim 1 , wherein the distance between adjacent projections is less than half of the length and less than half of the width of the dosing unit.

3. The container according to claim 1 , wherein the projections comprise a first ridge that extends in a longitudinal direction and additional ridges that are parallel to the first ridge.

4. The container according to claim 3 , wherein a width of the first ridge is less than a distance between adjacent ridges.

5. The container according to claim 3 , wherein the first ridge extends from the base towards an upper tub edge.

6. The container according to claim 5 , wherein the first ridge extends substantially over the distance between the base and the upper tub edge.

7. The container according to claim 3 , wherein the height of the first ridge varies in the longitudinal direction.

8. The container according to claim 3 , wherein, in cross section, the first ridge has a first ridge slope, a ridge summit and a second ridge slope, the first ridge slope and the second ridge slope bridging a gap between the ridge summit and the datum plane of the tub wall.

9. The container according to claim 8 , wherein the first ridge slope and the second ridge slope extend obliquely with respect to one another and form an angle of from 60 to 120°.

10. The container according to claim 6 , wherein a surface area of the base is smaller than a surface area of a tub opening.

11. The container according to claim 6 , wherein the dosing unit comprises at least one second active ingredient.
