  • Patent number: 9788993
    Abstract: A plug member integrally includes a base portion (35a) attached to a plug holder (31) to be mounted on a mouth portion of a container, a plug (34) engaged with an engagement portion (31c) provided in an outlet passage of the plug holder (31), and a resilient connection portion (35b) resiliently connecting the plug (34) to the base portion (35a). Before the first use, the outlet passage is closed with the plug member. In the first use, the container is squeezed to increase the internal pressure of the container. Thus, the plug (34) is disengaged from the engagement portion (31c) by the internal pressure. The outlet passage is thereafter constantly kept open.

  • Patent number: 8490839
    Abstract: In a filtering dispenser container which includes a plug attached to a mouth portion of a bottle thereof and having a liquid discharge passage, and a filter and a check valve provided in the discharge passage, air lock is prevented, even if the container contains a highly percolative liquid, by preventing a very small amount of liquid percolating the check valve from reaching the filter. In the filtering dispenser container, a dam (14) is provided between the check valve (23) and the filter (25) for retaining a very small amount of the liquid percolating the check valve (23) when the check valve is closed. Thus, the filter (25) is prevented from being wetted with the liquid percolating the closed check valve (23) during storage or delivery of the container before the first use of the container.

  • Patent number: 8033271
    Abstract: A diagnostic device for a fuel vapor treatment system having: a canister that captures fuel vapor generated in a fuel tank; a purge passage for purging fuel vapor from the canister to an intake passage of an internal combustion engine; a purge valve provided in the purge passage to adjust a flow rate of fuel vapor; a processing device that depressurize an fuel vapor path extending from the fuel tank to the purge valve via the canister by a pump and performs a diagnostic processing for diagnosing a leak of fuel vapor from the fuel vapor path based on a change in pressure in the fuel vapor path during depressurization; and an angle detection device that detects an angle of inclination of the vehicle. The processing device determines, based on an inclination angle of the vehicle detected by the angle detection device, whether the diagnostic processing can be performed.
