Is conveyed while rotating, and the rotating brush 110 makes sliding contact with the rotating container to clean the outer circumference of the container with the cleaning liquid from the liquid supply pipe 116.

However, since the cleaning liquid from the liquid supply pipe 116 by the conventional device is not warm water and is generated by a jet jet of water for a short time, the stain on the outer surface of the container cannot be softened, and therefore the cleaning becomes insufficient. there were. Further, since the rotating brushes 110, 110 are only arranged on one side of the container 103, there is a problem that it takes time to wash the container outside.

The present invention has been proposed to solve these problems.

(Means and Actions for Solving Problems) Therefore, according to the present invention, in a plant in which a recovery container is taken out of a box, and after cleaning, the container is filled with a new product liquid and then put into the box again, the dirty recovery from the box is recovered. Take out the container, and on the conveyor for supplying it to the washing machine, apply warm water discharged from the washing machine to the container to soften the dirt, and then rub the outer surface of the container with a rotating brush to put it in the washing machine. The outer surface of the container is cleaned before entering, and this is used as means and actions for solving the problem.

Further, the present invention, a fixed guide for transferring the container from the conveyor for transporting the container onto the container support rod that supports the lower end of the container, a container rotation rope that has a faster speed than the conveyor and contact drive the lower part of the container, and the same rope. Opposite fixed guides, rotating brushes installed on both sides of the container, pipes for sending hot water from the external washing machine to the container on the conveyor, and a container rubbed by the rotating brush. On the other hand, a structure including a water pipe for supplying the cleaning liquid is provided, and this is used as a means for solving the problem.

(Embodiment) The present invention will be described below with reference to the embodiments of the drawings. Figs. 1 to 4 show an embodiment of the present invention, and Fig. 1 is a side view showing an example of an apparatus for carrying out the method of the present invention. Fig. 2 is an enlarged side view of the container washing machine, Fig. 3 is a plan view of the same, and Fig. 4 is a sectional view taken along line AA of Fig. 2.
