  The present invention relates to a home permanent magnet magnetic therapy device cover.

Conventionally, a home with a sticking member that is used by sticking a home permanent magnet magnetic therapy device to a user's skin surface with a bandage, a patch, a seal or the like (hereinafter referred to as a sticking member) for the purpose of magnetic therapy effect. Permanent magnet magnetic therapy devices are widely known.
In such a home permanent magnet magnetic therapy device with a sticking member, the magnetism spreads beyond the skin surface side of the user, and the influence of the magnetism of the home permanent magnet magnetic therapy device may reach external objects and the like. is there. In particular, there is a great influence on recording media that use magnetism, and there is a problem that these recording media and, in turn, products that use the recording media (for example, cash cards) may become unusable.

  Conventionally, a domestic permanent magnet magnetic therapy device with an attaching member for solving such a problem is known (for example, refer to Patent Document 1 or 2).

FIG. 8 is a cross-sectional view for explaining the home-use permanent magnet magnetic therapy device 800 with an attaching member described in Patent Document 1 among them.
In addition, what is shown by the symbol H in FIG.

The home permanent magnet magnetic therapy device 810 includes a permanent magnet portion 820 having a permanent magnet 822 and silicon rubber 824, and a magnetic coating layer 830 formed on a surface of the permanent magnet portion 820 other than the surface of the user's skin H. Have
The magnetic coating layer 830 is an iron-cobalt alloy layer formed by a plating method.

  According to the home-use permanent magnet magnetic therapy device 800 with a sticking member described in Patent Document 1, a magnetic coating layer 830 is formed on the surface of the permanent magnet portion 820 other than the surface of the user's skin H. Therefore, the magnetic coating layer 830 can shield the magnetism to some extent and reduce the influence of magnetism on an external object or the like.

FIG. 9 is a cross-sectional view for explaining a home-use permanent magnet magnetic therapy device 900 with a sticking member described in Patent Document 2. As shown in FIG.

  However, in the home-use permanent magnetic therapy device 800 with a sticking member described in Patent Document 1, the magnetic coating layer 830 is formed by a plating method, so that the thickness of the magnetic coating layer 830 is not sufficient. In addition, the magnetic coating layer 830 is not completely alloyed, and as a result, there is a problem that the magnetism cannot be sufficiently shielded. There is also a method of completely alloying the magnetic coating layer by heat treatment, but in this case, undesirable alloying occurs between the permanent magnet and the magnetic coating layer, and the magnetic properties of the permanent magnet deteriorate. Therefore, it is not preferable.

  In addition, in the home-use permanent magnetic therapy apparatus 900 with an attaching member described in Patent Document 2, the magnetic shield material 930 is formed by molding a magnetic powder using a resin. There is a problem that the density of the magnetic material is low, and as a result, the magnetism cannot be sufficiently shielded.

  Therefore, the present invention has been made to solve each of the above-mentioned problems, and is used by being used for a home permanent magnet magnetic therapy device that is attached to a user's skin surface with an attaching member.
