The present invention has been made to achieve the above objects,
A space is created between the inner wall of the battery can and the annular protrusion added to the seal packing to hold a sealant effective in preventing creep leakage. This method involves compressing the battery can in the axial direction after sealing by conventional caulking, causing the sealing groove to protrude in the axial direction of the battery and contacting the annular protrusion to create a space for holding the sealant. It is characterized by having a sealed structure.

。Embodiment An embodiment of the present invention will be explained with reference to FIGS. 1 to 4. Normally, a cylindrical sealed battery is sealed by making a groove on the top of the battery can using a rotating roll, applying a sealant to the part that protrudes inside the can, inserting the top cover through the seal gasket, and opening the can. is caulked by plastic processing. An overview is shown in Figure 4.

ンチである。The sealant 6id adheres to the vicinity where the sealing groove 5 of the battery can 1 and the seal packing 2 come out of contact due to surface tension. From this state, the battery 9 is compressed in the axial direction as shown in FIG. As shown in FIG. 3, due to compression, the sealing groove portion protrudes in the direction of the battery axis and comes into contact with the annular projection 3 to form a contact portion 8. The annular projection 3 protrudes perpendicularly to the lower surface of the 7-lupanokin, and a space 7 is created between the battery can 1 and the seal packing 2 by the contact portion 8. The sealant is trapped in this space 7 to be held. The outline is as shown in Fig. 1. In the drawing, 10 is a receiving mold, 11 is a cylinder, and 12 is a punch.

果がある。Effects of the Invention As described above, according to the present invention, the sealing structure has a space for holding the sealant between the battery can and 7-ruvanoquine due to plastic deformation due to compression, so a long-term effect of the sealant is expected. This has the effect of improving reliability against liquid leakage, particularly against long-term creep leakage of alkaline electrolytes.
