A container has a bottom closed end, a top closed end and a chamber defined by them. A tubular member has an opening at its top which is detachably sealed. The tubular member is in communication with the chamber. A first and a second auxiliary tubes are in communication with the chamber and they are disposed on the top closed end of the chamber. The first auxiliary tube has a predetermined height, and the second auxiliary tube has a lesser height than the first. One end of a siphon tube passes through the seal of the second tube and is disposed adjacent to the bottom of the chamber. The other end of the siphon tube extends out of the second auxiliary tube and leads downward from the same.
