ONE PIECE CAP AND COMBINATION BETWEEN THE SAME AND CONTAINER

To provide a new one piece cap which enables an upper lid 8 to be held at an open position in a sufficiently reliable manner.SOLUTION: An opening 80 having a four-way frame is formed on an outer surface of an attachment wall 4 at the side which is connected through a hinge and engaging means 76 is provided at a vertical frame 82 of the opening 80. Further, an upper protruding piece 84 protruding to the radial outer side is formed on an outer surface of an upper lid 8, and engaged means 78 is provided on a side surface of the upper protruding piece 84. When the upper lid 8 is turned to an open position, the engaged means 78 gets beyond the engaging means 76, enters the inner side of the attachment wall 4 through the opening 80, and then is engaged with the engaging means 76. Furthermore, an outer surface of a skirt wall 52 is supported by the outer surface of the attachment wall 4.SELECTED DRAWING: Figure 2 【課題】上蓋８が開位置で充分確実に保持される、新規の１ピースキャップを提供すること。【解決手段】ヒンジ連結された側の装着壁４の外面に四方枠を有する開口部８０を形成して、係合手段７６を開口部８０の縦枠８２に設けると共に、上蓋８の外面に径方向外方に突出する上側突出片８４を形成して、被係合手段７８を上側突出片８４の側面に設けて、上蓋８が開位置に旋回せしめられると、被係合手段７８が係合手段７６を乗り越えて開口部８０から装着壁４の内側に進入した後に係合手段７６に係止せしめられると共に、スカート壁５２の外面が装着壁４の外面によって支持されるように構成する。【選択図】図２
