• the adapter having a central aperture through which a longitudinal axis of the jar passes when the adapter is positioned inside the jar, the central aperture being smaller than the removable cap of the dispensing container;
• wherein (i) the adapter is configured to maintain the dispensing container spaced from the inner wall of the jar and from the bottom of the jar;
• (ii) a gap is provided between the top of the jar and the cap of the dispensing container;
• (iii) a part of the cap of the dispensing container is further from the bottom of the jar than a part of the body of the dispensing container;
• (iv) the body of the dispensing container crosses the longitudinal axis of the jar;
• and (v) the dispensing container extends over more than half the diameter of the jar, and
• wherein the inner wall of the jar is tapered and wherein the inner wall and the adapter are configured such that the distance between the adapter and the inner wall varies as the adapter extends further into the jar.
