Abstract

The sheet mask includes multiple battery parts arranged such that electric currents flow along mimic muscles or flows of lymph. This allows an active ingredient to penetrate into in-body tissues more effectively and also allows the mimic muscles and the lymphatic vessels to be electrically stimulated. Forming the battery parts by using materials with low environmental load allows easy disposal of the sheet mask in everyday life.

First claim

The invention claimed is:

1. A sheet mask which is attached to a face for use, comprising:
a sheet mask main body; and
a battery part arranged on the sheet mask main body and configured to come into contact with the face when the sheet mask is worn, wherein the battery part includes a positive electrode portion, a negative electrode portion, and an electrically-conductive layer connecting the positive electrode portion and the negative electrode portion, wherein the positive electrode portion includes a positive electrode and a positive electrode portion separator, and the negative electrode portion includes a negative electrode and a negative electrode portion separator, wherein the positive electrode portion separator is arranged out of contact with the negative electrode and the negative electrode portion separator is arranged out of contact with the positive electrode, wherein the positive electrode portion separator is arranged out of contact with the negative electrode portion separator, and wherein the positive electrode portion separator and the negative electrode portion separator are configured to come into contact with the face when the sheet mask is worn.

2. The sheet mask according to claim 1 , wherein
for use of the sheet mask, the positive electrode portion separator and the negative electrode portion separator are impregnated with an active ingredient that serves a role of an electrolyte to start a battery reaction.

3. The sheet mask according to claim 1 , wherein the sheet mask main body is configured to operate as the electrically-conductive layer of the battery part.

4. The sheet mask according to claim 1 , wherein the positive electrode of the battery part contains carbonized cellulose having a three-dimensional network structure.

5. The sheet mask according to claim 1 , wherein the negative electrode of the battery part contains at least one of magnesium, zinc, aluminum, iron, calcium, lithium, and sodium.

6. The sheet mask according to claim 1 , wherein the battery part is arranged such that an electric current flows along a mimic muscle or a flow of lymph in the face.

7. A sheet mask which is configured to be attached to a face for use, comprising:
a sheet mask main body; and
a single battery part arranged on the sheet mask main body and configured to come into contact with the face when the sheet mask is worn, wherein the single battery part includes a positive electrode portion, a corresponding negative electrode portion, and a separator connecting the positive electrode portion and the negative electrode portion, wherein the positive electrode portion includes a positive electrode and a positive electrode portion electrically-conductive layer, the negative electrode portion includes a negative electrode and a negative electrode portion electrically-conductive layer, and wherein the positive electrode portion electrically-conductive layer is arranged out of contact with the negative electrode and the negative electrode portion electrically-conductive layer is arranged out of contact with the positive electrode, wherein the positive electrode portion electrically-conductive layer is arranged out of contact with the negative electrode portion electrically-conductive layer, and wherein the positive electrode portion electrically-conductive layer and the negative electrode portion electrically-conductive layer are configured to come into contact with the face when the sheet mask is worn.

8. The sheet mask according to claim 7 , wherein the sheet mask main body is configured to operate as the separator of the single battery part.
