Summary:To provide a container lid capable of quickly restoring a container to such an extent that continuous discharge is possible while ensuring sealing performance without inhibiting discharge of a content and the restoration of the container, and the container with the container lid on which the container lid is attached.SOLUTION: The container lid comprises a closed wall provided with a discharge opening through which a content of the container pass and a valve body closing the discharge opening, an attachment wall which is suspended from an outer peripheral edge of the closed wall and has a container fitting part on an inner surface, and an annular flexible seal piece formed on the attachment wall and extending radially inward from an inner circumferential surface of the attachment wall and having a thick part with a relatively increased thickness in the circumferential direction, an outside air flowing gap is formed between the annular projecting part and the annular flexible seal piece near the end of the thick part when the container lid is fitted to a mouth and neck part and an upper surface of the annular projecting part formed below introduction means in an outer container layer is in close contact with a lower surface of the annular flexible seal piece.SELECTED DRAWING: Figure 1 【課題】内容物の吐出や容器の復元を阻害せず密封性を確保しつつ、さらには連続吐出が可能な程度に容器を早く復元することが可能な容器蓋と、この容器蓋が装着された容器蓋付き容器を提供する。【解決手段】容器蓋は、容器の内容物が通過する排出開口が形成されると共に、該排出開口を閉じる弁体が配設される閉塞壁と、閉塞壁の外周縁部から垂下し、内面に容器嵌合部を有する装着壁と装着壁に形成されて当該装着壁の内周面から半径方向内方に延出するとともに、周方向において相対的に厚みが増大した厚肉部を有する環状可撓性シール片と、を具備し、口頸部に容器蓋が嵌合され、外側容器層のうち導入手段よりも下方に形成された環状突出部の上面と環状可撓性シール片の下面とが密接するとき、厚肉部の終端付近において環状突出部と環状可撓性シール片との間に外気導通隙間が形成される。【選択図】 図１
