ので、シール工程を短くしてシール作業を短時間化する
とともに、シール作業に必要な装置を全体として小型化
することが可能となる。According to the sealing device of the above-described embodiment, since the first and second pressing members 20 and 30 integrated with the single pedestal 10 can perform the two-stage sealing of the temporary seal and the ring seal, The process can be shortened to shorten the sealing work, and the device required for the sealing work can be downsized as a whole.
またピッチ印刷によるずれや、突状を有する特殊シール
においてもずれがなくなる。Further, the deviation due to the pitch printing and the deviation even in the special sticker having the protrusion are eliminated.
さらに、蓋材のしわ，縮み，カールなどの発生を防止し
