  • Publication number: 20200307228
    Abstract: A liquid storage bottle includes a bottle main body, a nozzle having a discharge port through which a liquid stored in the bottle main body is discharged, a cap mountable on the nozzle and a sealing unit sealing the discharge port when the cap is mounted on the nozzle. The sealing unit includes an annular first rib, an annular second rib and an annular third rib. The outer peripheral surface of the first rib is inclined with respect to the axial direction of the nozzle so that a diameter decreases toward a tip portion of the first rib and the inner peripheral surface of the third rib is inclined with respect to the axial direction of the cap so that a diameter increases toward a tip portion of the third rib.

  • Patent number: 10219733
    Abstract: In this urine flow meter, a water wheel which is caused to rotate by a flow of urine from a urine flow passage tube is provided at a lower end side of the urine flow passage tube. The shape of a tip portion of the urine flow passage tube that causes urine to hit on the water wheel constitutes a nozzle part in which the tip-side is acutely processed, and an opening is formed in a sidewall surface of the tip-side. A guide is provided in a urine flow passage and is disposed in such a way that a tip of the guide is elongated as far as a tip-side region of the mine flow passage tube. The water wheel is caused to rotate by the flow of urine, and the urine flow rate can be detected on the basis of the rotation detection information.
