PROBLEM TO BE SOLVED: To solve the problem of existing paper containers in which a lid and a bottom are locked, and to prevent them from separated, for an example, a seal is pasted to be applied on both the lid and the bottom to retain them, which inhibits a repeated use while keeping sealability once being opened.SOLUTION: To provide a sealed type paper container capable of repeatedly opened/closed its lid and bottom, in which a lower part 1 of a lid upper part inner curl being curled inside and an upper part 2 of a top plate are bonded; a lower part 3 of the top plate and an upper part 5 of a bottom upper part outer curl being curled outside are brought into contact; an upper part 4 of a lid lower part inner curl being curled inside and a lower part 6 of the bottom upper part outer curl are brought into contact. 【課題】従来、蓋と底を嵌め合わせた後、はずれないようにするためには、一例としてシールを蓋底両方にかかるように貼ってとめていた。そのため一度開けてしまうと、繰り返しての密閉性を保つ使い方は、出来なかった。【解決手段】内側にカールさせた蓋上部内カールの下側部１と天板の上側部２は接着され、天板の下側部３と外側にカールさせた底上部外カールの上側部５は当接され、内側にカールさせた蓋下部内カールの上側部４と前記底上部外カールの下側部６が当接されたことを特徴とする、繰り返し蓋と底を開け閉めできる密閉型紙容器を提供する。【選択図】図１
