The present invention relates to a container for anal irrigation. In particular it relates to a rigid container which is easy to operate and which easily is transformed from a storage configuration to a ready-to-use configuration. In one aspect the invention relates to a container for an anal irrigation system. The anal irrigation system comprises an anal probe; a reservoir for holding an irrigation liquid (e.g. water); a pump mechanism for pumping a fluid (e.g. air) into the reservoir; and a liquid tube connecting the reservoir with the anal probe. The container comprises an outer chamber wall, defining at least partly the outer dimensions of the container and an inner chamber wall arranged within the outer chamber wall, said outer chamber wall and inner chamber wall defining the reservoir. This provides a reservoir having a small surface area when filled with irrigation liquid. Thus only a low pressure is necessary to evacuate the irrigation liquid from the reservoir and out through the anal probe.
