PURPOSE:To enhance washing effect, by forming a stepped part to the inner surface of the lower part of a hollow container and providing a washing solution supply port to the side surface of the upper part of the stepped part. CONSTITUTION:An inside hollow container 5B having a drain port 3B provided to the lower part thereof is mounted inside an outside hollow container 5A having a drain port 3A provided to the lower part thereof. A step part 8 is formed to the lower end of the lower part of the inside hollow container 5B by the protruding part 7 protruding from the inner peripheral surface 5b of the container 5B in the inner peripheral direction thereof. The washing solution supply port 1 piercing through the outside hollow container 5A and the inside hollow container 5B is provided to the side surface of the container 5B at the position above the stepped part 8 and an air vent hole 9 is provided at the circumferential position of the inside hollow container 5B. When an article 4 to be washed such as a nozzle or stirrer is guided into the inside hollow container 5B and a washing solution is supplied from the supply port 1, a water film 10 is formed to the step part 8 so as to cover the drain port 3B and the washing solution revolves along the inner peripheral surface 5b of the inside hollow container 5B. By this method the washing of the article 4 to be washed can be effectively performed. |
