PROBLEM TO BE SOLVED: To utilize a bottle as a timer by partitioning a cylindrical member for covering the outer periphery of two bottles with a circular plate member having two holes and operating one hole as a liquid flow-out hole and the other hole as a bubble generation hole. SOLUTION: A first circular plate 13 of a circular plate member 12 has two holes, and a cylindrical part projecting in different directions from each hole has a narrow tip, thus forming a small aperture. A cylindrical member 11 that the first circular plate 13 partitions in a diameter direction engages as screw groove being formed on the inner-periphery surface of both edges of a large-diameter cylindrical part 11L and a small-diameter cylindrical part 11S being fitted to a flight provided on the outer-periphery surface of the mouth of bottles 2 and 1, thus becoming a placement part and forming the bottle 1 and 2 in one piece. In this case, when a liquid, for example, water is loaded into the bottle 1, the water drops as a watedrop from one hole of the circular plate member 12 into the bottle 2, air in the bottle 2 rises into the water of the bottle 1 as a bubble from another hole. The generation time of the bubble is determined, for example, by a bottle volume, and amount of liquid, the number of holes, and a hole diameter, so that it can be utilized as a timer. |
