Abstract: A certain amount of contents is easily sprayed by one pressing operation. A metered spray unit 10 being mounted on a stem 23 of a valve 22 that is provided on the upper portion of a container body 21, configured to spray a certain amount of contents in a container body 21, includes an outer cylinder 30 which is provided with a stem insertion hole 30a into which the tip of the stem 23 is inserted and the inner wall thereof is fixed to the stem, a metering chamber 35 connected to the stem insertion hole 30a, the metering chamber being an internal space having a predetermined capacity, connected to the stem insertion hole 30a, and an spray port 33 communicating with the metering chamber 35, a plug member 40 that is inserted from the inside of the metering chamber 35 into the spray port 33 for blocking the spray port 33, a push button 51, an elastic member 60 for supporting the push button 51 on the outer cylinder 30, and a shaft member 50 connected to the push button 51.

Abstract: An aerosol dispenser having a metering valve mechanism having a metering chamber and a propellant-accommodating space region configured to be isolated from each other by an annular piston, and a metering formation seal valve configured to isolate the metering chamber from a contents accommodation space region in a propelling mode. In a contents filling mode the seal valve is moved by the flow of the filled contents in a direction away from the stem to allow the filled contents to flow into the contents accommodation space region.

Abstract: An expanded housing (2) including an outer tubular portion (2a), a center-top tubular portion (2b), an annular ceiling portion (2c), and a center-bottom tubular portion (2d) is an integrally molded plastic product. Vertical plate rib-shaped portions (2h) for increasing strength are similarly integrally molded between the outer tubular portion (2a) and the center-top tubular portion (2b). An inner passage region (B) for upward passage of content is set in the center tubular portion (2b). A housing cover (28) provided in such a form as to surround the lower side of the expanded housing (2) forms an outer passage region (A) which is disposed between the housing cover (28) and an outer peripheral surface of the expanded housing (2) so as to extend downward from an upper-end-side inner space region of an inner bag-shaped container (1g) to the inner passage region (B).

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).

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.

Abstract: A flow rate regulator of a unit structure, in which the mechanism keeps constant the amount of injection of the contents in an aerosol container independent of a variation in pressure of gas for content ejection. The flow rate regulator unit has an outer sheath member (15), an inner sheath member (16), piston members (17, 18), a coil spring (25), and an ejection piece (19). The contents are ejected in substantially the following route: “hole (15a)—annular space region (21) for outer path—hole (16a)—annular space region (22) for inner path—holes (17b, 18b)—inside path (18c)—valve action region (20)—penetration section (16d)—groove-like sections (16f, 19a)—ejection hole (19c).

Abstract: A spray nozzle mechanism capable of forming spray contents into fine particles. A channel setting core is fixedly placed in a space in a button body, between an output hole of a vertical path and a hole for discharging contents to the external space. Swirls in the same swirling direction are formed by upstream recessed paths continuous from the vertical path and downstream recessed paths continuous to the discharge hole. Also, the spray nozzle mechanism has ribs. The ribs move initial swirls created by the upstream recessed paths to the corresponding downstream recessed paths, where the initial swirls are moved in a state where they are separated as far as possible.

Abstract: The tip-stop mechanism for an aerosol container has a needle valve placed into a passage area and closes discharge hole due to plate springs engagement with tapered surfaces of the needle valve. An operation lever is supported on a pivot shaft and when pressed downward forces a portion of the lever to cause the needle valve to move backward, opening the discharge hole. After that, the operation lever engages the upper surface of the spout and moves downward together with the spout and the stem, thereby the lever is shifted to an operation mode.

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.
