  • Patent number: 8893933
    Abstract: Disclosed is an inverted constant-volume injection mechanism using an actuator which comprises a valve member (5), a movable member (6), a pressing-on operation member (7), and a pressing operation lever (8). On the basis of an operation by a user to hold a container main body and press the pressing-on operation member (7) onto the scalp (13) or a pressing operation by the pressing operation lever (8), first, output valves (5a, 7d) of the actuator art closed and a flow-in valve (4b) of a stem (4) is opened so that the content in the container main body flows into a constant amount chamber (A) defined between the flow-in valve (4b) to the output valves (5a, 7d).

  • Patent number: 8245887
    Abstract: A content discharge mechanism for a container with a pump has a discharge outlet that is fixed in position. The device has an operation button and a cylindrical piston that move as one, as well as a ball valve that rests on a seat. The ball valve opens as the cylindrical piston retracts after an actuation to allow more fluid into the upstream passage chamber. A downstream passage with a valve for dispensation fluidly communicates with the upstream passage through a hole. As the cylindrical piston and its seal slide over the hole, the discharge from the downstream passage stops.

  • Publication number: 20090119867
    Abstract: An electric vacuum cleaner includes an electric blower, a driver for driving the electric blower, a determination controller for controlling the electric power supply to the electric blower by transmitting a signal to the driver, and a dust amount sensor for sensing the amounts of dusts of different sizes. The determination controller controls the electric power supply to the electric blower based on the amounts of dusts of the different sizes sensed by the dust amount sensor.

  • Publication number: 20090008415
    Abstract: A content discharge mechanism of a pump type container, which prevents the position of a content discharge outlet from moving following discharge operation is disclosed. The mechanism includes an operation button 1; a sheath-shaped piston 2 interlocking with the operation button 1; a suction valve including annular reception surface 3c and spherical body 5 actuated in response to the movement of the sheath-shaped piston 2; an upstream passage A formed between the sheath-shaped piston 2 and the suction valve; a downstream passage B communicated with the upstream passage A and formed between it and a discharge outlet 8b; and a pressure storage type discharge valve including annular edge part 8a and annular tapered surface 9a. In a discharge finishing mode, the pressure in the contents is lowered by permitting the downstream side passage B to be communicated with a passage outside space region E via a hole 3f, to close the discharge valve.

  • Publication number: 20080017672
    Abstract: There is provided a novel flow rate regulator mechanism of the type where an external flow rate regulator unit for regulating a change in gas pressure in an aerosol container is mounted between a housing and a suction pipe. The flow regulator unit 10 is mounted between the housing 41 and the suction pipe 42. A time ratio of an inlet part A, that serves as a part of passage of a content in the container, being opened is smaller as pressure of compressed gas is higher like the compressed gas at an initial stage of its use. In a stationary mode where pressure of the passage of a content is uniform, a flow rate adjusting valve 14 moves upward against a spring 15 with the aid of the uniform pressure to substantially close the inlet part A. In an actuation mode, a content in a downstream side space region of the inlet part A is first discharged to lower pressure there, so that the flow rate adjusting valve 14 moves down by the action of the spring 15 to open the inlet part A.

  • Patent number: 6921005
    Abstract: A dispensing apparatus and an aerosol type dispenser therewith for discharging contents stored in a measured chamber effectively. The dispensing apparatus is comprised of a cylindrical portion for providing a circular recess portion which keeps a part of the contents in the measured chamber and a cylindrical skirt for providing a detour in the circular recess portion. The cylindrical portion and/or the cylindrical skirt form grooves so as to make a sectional area for flowing contents smaller. In mode in use, the upstream contents positioned inside space of the cylindrical skirt take a long way around the circular recess portion at high speed and high pressure, therewith contents settled in the circular recess portion are forced to sent to the passage of the valve stem certainly.
