摘要： Provided is a spray container capable of removing and separating a pump from a container with a small force after use of contents.
An engagement portion is disposed around a button such that a fastening ring crimping a pump unit to a neck-shaped portion of the container can be pushed down by pressing down the button of the pump unit. Accordingly, after all the contents in the spray container are used, the pump unit can be removed from the neck-shaped portion of the container.

摘要： 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. The elastic member 60 has an amount of displacement due to the pressing force applied to the push button 51, being smaller than the amount of displacement when applying the same pressing force to the spring for urging the stem 23 within the valve 22.

摘要： 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). A cone-shaped piece (28k) enters into an individual upper-end-side inner space region set between adjacent vertical plate rib-shaped portions (2h) and acts as an entrance portion of the outer passage region (A). Thus, residual air between vertical plate rib-shaped portions is reliably discharged.

摘要： 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 are 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). On the basis of a releasing operation performed thereafter, the stem (4) returns to a static mode position and the flow-in valve (4b) is closed, so that the content in the constant amount chamber (A) passes through the output valves (5a, 7d) which are opened by the effect of the liquefied gas, and is injected to the external space through a hole (7c) of the pressing-on operation member (7).

摘要： In an aerosol-type invertible valve mechanism, the present invention addresses the problem of preventing the occurrence of "gas entrainment" of vaporized gas in the contents, stabilizing continuous spraying of the contents and improving efficient use of invertible valve mechanism parts without especially changing the size or material of the moving valve itself. The vertical spacing (L), in the upright state, between the lower end portion of a ball valve (7), which closes an upper central cylindrical section (6b) in the upright state and prevents the inflow of vaporized gas inside the upper part of a container body into a shared invertible passage (C), and the upper end portions of outflow holes (6f), which are the beginning portions of the shared invertible passage (C) and are common to an upright inflow passage (A) and an inverted inflow passage (B), is set to be at least 3.5 mm, more preferably, at least 3.7 mm. Said setting prevents "dancing" of the ball valve (7) due to upward flow energy of the contents flowing in from the upright inflow passage (A) in the upright operation mode, and is able to prevent the occurrence of "gas entrainment" of vaporized gas in sprayed contents that occurs as a result of the gas entering the shared invertible passage (C) via the "dancing" ball valve (7).

摘要： A novel flow rate regulator mechanism in which a flow rate regulator unit responsive to a change in gas pressure inside an aerosol container is externally attached between a housing and a suction tube. A flow rate regulator unit (10) is attached to a housing (41) and to a suction tube (42). The rate of time in which an inlet (A) as a part of a contents passage is in an open state is less when pressure is high such as in the initial stage of use of a compressed gas. In a stationary mode (pressure in the contents passage is uniform), a flow rate regulation valve (14) moves upward against a spring (15) because of the uniform pressure, bringing the inlet (A) to an almost-closed state. In an operation mode, contents in a downstream side space region are discharged first and the pressure in the region lowers, and the spring (15) causes the flow rate regulation valve (14) to move downward to open the inlet (A). Then, the contents flow into the downstream side space region to raise the pressure, causing the flow rate regulation valve (14) to move upward to bring the inlet (A) to the almost-closed state again. In the operation mode, this operation is repeated.

摘要： A flow rate regulation mechanism 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. A 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). "An annular skirt section (17a) moves in the left-right direction based on a magnitude relation between force in the right direction caused by ejection gas pressure and acting on the piston members (17, 18) and urging force to the left direction caused by the coil spring (25), and this changes an inflow cross-sectional area from the hole (16a) for flow rate adjustment to the annular space region (22) for inner path.
