Abstract

PURPOSE: To close up tight perfectly at high efficiency by cutting an unsealing part of specified shape at the top of a cover, squeezing the cut part from above and below to contact the cut ends closely with each other, and applying a compound to the part.
CONSTITUTION: A flange part 5a is formed on the periphery of a disk-shaped cover 5 made of tinned sheet iron by a press, and periphery of a top plate 5b is cut to circular form by a press. Inside of the cut part becomes an open part 5c. The cut part 5d is squeezed from above by a press to bring the cut faces into close contact. Then, a compound 6 is applied to the lower side of the cut face 5d to hold the unsealing part.
