The invention relates to a foldable bag that can be unfolded from an essentially flat initial state into an unfolded final state, provided with at least a first, a second and a third sheet for forming, respectively, a first, a second and a third wall of the foldable bag. The first sheet is joined to the second sheet via the third sheet, which third sheet in the initial state is folded along a fold line, wherein the fold line in the initial state is between the first and the second sheet. The foldable bag furthermore has an opening in the first sheet. The fold line of the third sheet in the initial state extends underneath the opening to form a channel between the first and second sheet past the opening. The invention furthermore relates to a combination of a container and empty bag as well as method for the use thereof, wherein the bag is fixed to the peripheral wall of the container by means of a first and a second fixing.

The invention claimed is: 1. A combination comprising a container and an empty bag that can be unfolded from a flat, empty state into a filled final state;wherein the container has a walled enclosure that defines a container chamber, which walled enclosure comprises a base and a peripheral wall that is upright in a height direction from the base;wherein the bag comprises a first, a second, a third and a fourth sheet for forming, respectively, a first, second, third and fourth bag wall;wherein each of the sheets is rectangularly shaped, wherein the first and the second sheets are at least approximately the same size, and wherein the third and the fourth sheets are at least approximately the same size;wherein the first sheet has a first end edge, a second end edge, a first side edge, and a second side edge, the first and the second end edges being divided into three sections, the three sections including a first outer section, a second outer section, and an inner section;wherein the second sheet has a first end edge, a second end edge, a first side edge, and a second side edge, the first and the second end edges being divided into three sections, the three sections including a first outer section, a second outer section, and an inner section;wherein the third sheet has a first end edge, a second end edge, a first side edge, and a second side edge;wherein the fourth sheet has a first end edge, a second end edge, a first side edge, and a second side edge;wherein, in the flat empty state, the third and the fourth sheet are each folded along a fold line;wherein, in the flat, empty state, the fold line of the third sheet and the fold line of the fourth sheet are between the first and the second sheet facing one another;wherein the fold lines extend essentially in the height direction of the container;wherein the fold lines, the height direction of the container, and each of the side edges of the sheets are at least approximately parallel to each other and are at least approximately perpendicular to each of the end edges of the sheets;wherein the first outer section of the first end edge or the first sheet is joined to the first end edge of the third sheet;wherein the inner section of the first end edge of the first sheet is joined to the inner section of the first end edge of the second sheet;wherein the second outer section of the first end edge of the first sheet is joined to the first end edge of the fourth sheet;wherein the first outer section of the second end edge of the first sheet is joined to the second end edge of the third sheet;wherein the inner section of the second end edge of the first sheet is joined to the inner section of the second end edge of the second sheet;wherein the second outer section of the second end edge of the first sheet is joined to the second end edge of the fourth sheet;wherein the first sheet of the bag is provided with a first opening for emptying the bag, the first opening being connected to the peripheral wall;wherein the foldable bag in the filled final state has dimensions that essentially correspond to those of the container chamber;wherein the first sheet of the bag is provided with a second opening for filling the bag;wherein the first opening and second opening are fixed to the walled enclosure;wherein the first opening is provided at the base of the container and the second opening is provided at the top of the peripheral wall such that, between the first opening and second opening, the bag is in contact with the peripheral wall over essentially the entire height of the peripheral wall as well that, with the container upright and from the flat, empty state, the bag unfolds from the first opening along the base and from the base into the top of the container chamber, wherein the fold line of the third sheet and the fold line of the fourth sheet in the initial state extend underneath the first opening to form a channel between the first and second sheet past the first opening, and wherein the bag is folded along an upper axis and a lower axis to define a U shape, with a bottom section of the bag that adjoins a base end of the channel and is configured to flap open around the lower axis and expand as it collects a first portion of liquid received in the bag.
