PROBLEM TO BE SOLVED: To provide a container which swiftly flows a liquid in a container body to an injection port and is less likely to be damaged.SOLUTION: A container 1 includes: a container body 2 for storing a cleaning liquid therein a nozzle 4 having an injection port 43 for injecting the cleaning liquid stored in the container body 2 when the container body 2 is pressed and a check valve 70 which is provided between the container body 2 and the injection port 43 and blocks the cleaning liquid from flowing back to the container body 2. The check valve 70 has a cylindrical shape in which an upper end is closed by an end wall 71 and an opening 74 for flowing the cleaning liquid from the container body 2 thereinto is provided at a lower end. The end wall 71 faces the injection port 43 through a space 46 of the nozzle 4. The end wall 71 includes notches 72a, 72b, 72c, 72d, and sections 73a, 73b, 73c, 73d which are separated by the notches 72a, 72b, 72c, 72d and are elastically deformable.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】容器本体内の液体を噴射口に向けて勢いよく流せるとともに破損しにくい容器を提供することを目的とする。【解決手段】 容器1は、洗浄液を内部に貯留する容器本体2と、容器本体2が押圧された際に、容器本体2の内部に貯留された洗浄液を噴射する噴射口43を有するノズル4と、容器本体2と噴射口43との間に設けられ、容器本体2に洗浄液が逆流することを阻止する逆止弁70とを備える。逆止弁70は、上端が端壁71で塞がれ、下端に容器本体2からの洗浄液を流入させる開口74を有する筒状を呈する。端壁71は、噴射口43とノズル4の空間46を介して相対する。端壁71は、切り込み72a,72b,72c,72dと、切り込み72a,72b,72c,72dにより区切られるとともに、弾性変形可能な切片73a,73b,73c,73dとを含む。【選択図】図4
