Abstract

The object of the present invention is to provide a metal container washing apparatus which can obtain hydrogen peroxide for generating hydroxyl radicals and electrolytes using a simple configuration and a simple method and which is small and has excellent portability and storability, and the present invention provides a washing apparatus that washes a metal container of the present invention includes a negative electrode that applies a negative voltage to a metal container to which a washing solution, in which a hydrogen peroxide generating agent generating hydrogen peroxide when dissolved in water is dissolved, is added; a positive electrode that applies a positive voltage to the washing solution; and a power supply that applies a voltage between the negative electrode and the positive electrode, and the inner surface in the container is washed with hydroxyl radicals generated at the time of application of the voltage. It is possible to obtain both of hydrogen peroxide that generates hydroxyl radicals having a strong decomposition ability with respect to stains and electrolytes that allow the washing solution to be electrolyzed with a low voltage such as a voltage that supplied by a battery.

First claim

What is claimed is:

1. A metal container washing apparatus configured to wash a metal container for accommodating beverages, the metal container washing apparatus, comprising:
a first electrode configured to apply a negative voltage to the metal container;
a second electrode positioned and configured to apply a positive voltage to a washing solution in the metal container such that when the metal container contains a washing solution having a hydrogen peroxide generating agent and water, the hydrogen peroxide generating agent is dissolved to create hydroxyl radicals for washing an inner surface of the metal container;
a power supply that applies a voltage between the first electrode and the second electrode, and an apparatus body including a base, the base configured to support the first electrode and the second electrode, and a lower surface of the base sized and shaped to be positioned across an opening end of the metal container; and,
the base includes a step portion having a cylindrical portion and a reversed truncated cone-shaped portion, the step portion also having a lower opening configured to have the second electrode inserted therethrough.

2. The metal container washing apparatus according to claim 1 ,
the second electrode has a rod shape and is movable in the metal container in a vertical direction.

3. The metal container washing apparatus according to claim 1 or 2 ,
wherein the hydrogen peroxide generating agent is at least one selected from the group consisting of percarbonate, perborate, and persulfate.

4. The metal container washing apparatus according to claim 1 or 2 , wherein the first electrode electrically comes into contact with and is connected to a metal portion of the metal container by being placed on the opening end of the metal container whose metal is exposed.

5. The metal container washing apparatus according to claim 1 ,
wherein the first electrode has a flat disk-shape, and a first electrode hole is formed in a center portion of the disk-shaped first electrode;
the second electrode has a rod-shape;
a diameter of the first electrode hole is larger than a diameter of the rod-shaped second electrode; and
an outer diameter of the flat disk-shaped first electrode is larger than a diameter of the opening end of the metal container.

6. The metal container washing apparatus according to claim 1 , wherein the second electrode has a first section and a second section.

7. The metal container washing apparatus according to claim 1 , wherein the base includes a lower inner peripheral edge, and wherein the first electrode is fitted between the step portion and the lower inner peripheral edge.

8. A metal container washing apparatus configured to wash a metal container for accommodating beverages, the metal container washing apparatus, comprising:
a first electrode configured to apply a negative voltage to the metal container;
a second electrode positioned and configured to apply a positive voltage to a washing solution in the metal container such that when the metal container contains a washing solution having a hydrogen peroxide generating agent and water, the hydrogen peroxide generating agent is dissolved to create hydroxyl radicals for washing an inner surface of the metal container;
a power supply that applies a voltage between the first electrode and the second electrode, and an apparatus body including a base, the base configured to support the first electrode and the second electrode, and a lower surface of the base sized and shaped to be positioned across an opening end of the metal container;
the apparatus body also includes a lid; and,

wherein the lid includes a locking portion and the base includes a lock-receiving portion, such that the locking portion and the lock-receiving portion can fix the lid and base to each other.

9. The metal container washing apparatus according to claim 1 , further comprising a metallic plate spring connected to a positive pole of the power supply in pressure contact with the second electrode.

10. The metal container washing apparatus according to claim 1 , further comprising a packing to facilitate positioning of the second electrode.

11. The metal container washing apparatus according to claim 1 , further comprising a switch that turns the power supply on or off.

12. The metal container washing apparatus according to claim 1 , further comprising an auxiliary electrode.
