PAPER-MADE LID AND CONTAINER WITH PAPER-MADE LID

PROBLEM TO BE SOLVED: To provide a paper-made lid which can obtain sufficient shape retention and strength, and is therefore pratical, and a container with the paper-made lid.SOLUTION: The paper-made lid is formed by press-molding of one board base paper according to a size of an opening of a container body which has the opening at an upper portion. The paper-made lid comprises a bottom 11, a side wall part 12 which is connected to the bottom 11, a flange part 13 which is connected to the side wall part 12, and extends outward in a substantially horizontal direction, and an edge winding part 14 which is formed on an outer peripheral edge of the flange part 13. By such a configuration, the paper-made lid can obtain sufficient shape retention and strength, and is therefore practical.SELECTED DRAWING: Figure 7 【課題】十分な保形性や強度が得られ実用的な紙製蓋及び紙製蓋付容器を提供する。【解決手段】紙製蓋は、上方に開口部を有する容器本体の開口部のサイズに合わせて、１枚の板紙原紙からプレス成形によって形成される紙製蓋であって、底部１１と、底部１１に接続する側壁部１２と、側壁部１２に接続し、外方方向に略水平方向に延びるフランジ部１３と、フランジ部１３の外周縁に形成された縁巻部１４とを備える。このように構成すると、縁巻部及びフランジ部により十分な保形性や強度が得られるので、実用的な紙製蓋となる。【選択図】 図７
