る。Conventional Structures and Problems Electrolytes used in button-type batteries, such as alkaline electrolytes, tend to creep by themselves, particularly along the surfaces of electrically charged metal members. Therefore, for example, a seal plate 1 and a sealing ring 2 are combined as shown in FIG.
Inside is an alkaline electrolyte impregnation material 8. In a button type battery that accommodates a separator 9, a positive electrode ring 10, and a positive electrode 18 and is integrated with a negative electrode part, when the sealing plate 1 and the sealing ring 2 are integrated, a seal is applied to improve the airtightness of the contact surface. Material 6 was applied. This sealing material 5 is a combination of two types of materials, one of which is placed on the sealing plate 1 as shown in FIG. 2, and the other on the sealing ring 2 as shown in FIG. The sole materials T are applied respectively, and they are combined together to form the sealing body shown in FIG. 4.
ここで、封口板１にシール材６を塗布する際、例えば第
５図に示すような方法が採られてきた。Here, when applying the sealing material 6 to the sealing plate 1, a method as shown in FIG. 5, for example, has been adopted.

し、均一に塗布することが難しいという問題があった。In the method shown in Figure 1, a tapered roller 16 having an appropriate angle (0° to 90°) is rotated about a horizontal axis in a tank 14 in which the sealing material 6 is stored, and the film thickness is adjusted. By adjusting the gap between the plate 16 and this tapered roller 15, the thickness of the film that adheres to the surface of the tapered roller 16 of the /-ru material 6 is adjusted. Then, the sealing plate suction pin 17 vacuum-suctions the sealing plate 1 to the lower part of the sealing plate 1, and while rotating the sealing plate suction pin 17 while adsorbing the sealing plate 1, the sealing plate 1 is attached to the film of the sealing material 6 on the surface of the tapered roller 16. The sealing material 6 is applied to the sealing plate 1 by passing the sealing material 6 so that the outer edges thereof are in contact with each other. However, with this method, it is not easy to adjust the gap between the tapered roller 15 and the film thickness adjusting plate 16 or to make the outer edge of the sealing plate 1 contact with the sealing material 6 on the surface of the tapered roller 16 while passing through the sealing plate. In particular, in the case of a sealing plate 1 for a small and thin coin-type battery, the sealing plate 1 itself is small and thin, and the amount of sealant 6 applied is small, so the outer edge of the sealing plate 1 is coated with sealant. 6
In order to uniformly apply the film, strict precision is required of the device, such as the precision of the gap between the tapered roller 15 and the film thickness adjustment plate 16, and the rotational precision of the tapered roller 15 and the sealing plate suction bottle 17. Further, as the viscosity of the sealant 6 changes, the thickness of the sealant 6 adhering to the surface of the tapered roller 15 changes, making it difficult to apply it uniformly.

It is connected to a pump P that supplies water, and moves in parallel in the vertical direction. The sealing ring 2 is attached to the shaft 13
The sealing ring is vacuum-adsorbed by the suction head 12 fixed to the sealing ring, and as shown in FIG.
By supplying a certain number of sealants 7 through the coating needle 11 while rotating the sealing ring 2, the inner surface of the sealing ring 2 can be uniformly coated with the sealant 7.

As shown in FIG.
The sealing material 6 is uniformly applied to the inner surface of the housing as shown in FIG. A sealing body is constructed by integrating the sealing ring 2 coated with two types of sealing materials 6 and 7 so as to overlap with the sealing plate 1 in this manner.
