, The residual pressure of the small diameter cylinder 11 is introduced into the plunger 2, and a sufficient suction pressure required in the subsequent liquid suction step is formed inside the small diameter cylinder 11.

The opening timing (outside air introduction) of the outside air sealing portions 120d and 121d by the above-mentioned outside air introducing rib 11d and the residual pressure sealing portion 1 by the residual pressure introducing rib 11e.
The opening timing of 20e (introduction of residual pressure) is as follows (a)
It is done in the order of ~ (c). (a) The outside air seal portions 120d and 121d reach the outside air introducing rib 11d and are opened to introduce the outside air.

The passage of liquid to e is blocked.

(3) Small diameter cylinder 11 and large diameter cylinder 13
When the trigger 8 is further pulled after the internal pressure of is accumulated at a predetermined pressure, as shown in FIG. 3, a pressing force is generated due to a difference in cross-sectional area between the small diameter cylinder 11 and the large diameter cylinder 13 (cylinder portion 13b). The rearward movement amount of the plunger 12 is larger than the rearward movement amount of the large diameter cylinder 13 due to the turning operation of the trigger 8, and the contact portion 1 of the large diameter cylinder 13 is
3f and the front end 121e of the sub-plunger 121 are separated from each other. As a result, the liquid material L becomes the nozzle portion 1

(4) When the trigger 8 is pulled to the end point in the process of jetting the liquid from the nozzle portion 13c of the large diameter cylinder 13, the residual pressure seal portion 120e of the main plunger 120 is replaced by the residual pressure introducing rib of the small diameter cylinder 11. 11e, and the residual pressure and residual liquid of the small diameter cylinder 11 flow out through a residual pressure introduction path that forms a gap between the outer peripheral surface of the main plunger 120 and the inner peripheral surface of the small diameter cylinder 11, and the gas-liquid introduction hole 11c. Flow into. Then, since the residual pressure and the residual liquid in the small diameter cylinder 11 flow into the container body 2 through the gas / liquid introducing passage 14 and the gas / liquid introducing holes 7b and 9h, the hydraulic pressures in the small diameter cylinder 11 and the large diameter cylinder 13 are increased. descend. Thereafter, due to the elastic force of the spring 15, the distal end portion 121e of the sub-plunger 121 seals the contact portion 13f of the large-diameter cylinder 13 and stops jetting from the nozzle portion 13c. The eruption can be suppressed.

Therefore, the spray container 1 has the following (A)-
It has the characteristic structure of (F). (A) Outside air seal portions 120d and 121d of the plunger 12
The multi-stage structure (FIG. 5) of the plunger 12 includes a plurality of outside air seal portions 120d that form a plurality of stages (two stages in this embodiment) in the axial direction (longitudinal direction).
121d is provided.

The outside air seal portion 121d is shown in FIG.
As shown in the figure, it is provided on the rear part of the sub-plunger 121 and is located on the outer side of the small-diameter cylinder 11. The outer outside air seal portion 121 d forms an expanding skirt shape (tapered shape) toward the inner side of the small-diameter cylinder 11 and slides on the inner surface of the small-diameter cylinder 11. Outside air seal part 121
The preferred spread angle θo of d is 6 to 12 degrees, and the preferred sliding contact length A with the inner surface of the small diameter cylinder 11 is 0.1 to 1.0 mm.

The inside / outside air seal portion 120d is shown in FIG. 5 (B).
As shown in the figure, it is provided at an intermediate portion of the main plunger 120 and is located inside the small-diameter cylinder 11. The inner / outside air seal portion 120 d forms an expanding skirt (tapered) toward the outer side of the small-diameter cylinder 11 and slides on the inner surface of the small-diameter cylinder 11. Inside / outside air seal 120
The preferred widening angle θi of d is 10 to 16 degrees, and the preferred sliding contact length B with the inner surface of the small diameter cylinder 11 is 0.1 to 1.0 mm.

Therefore, in the spray container 1, this
Depending on the configuration of (A), there are the following actions. When the trigger 8 is pulled, the gas is discharged together with the residual pressure in the small-diameter cylinder 11, and the gas-liquid introduction hole 11 in the inner surface of the cylinder 11 is released.
around c, the outside air seal portion 120d of the plunger 12,
Residual liquid sandwiched between 121d and the residual pressure seal portion 120e is supplied to a plurality of outside air seal portions 1 multiplexed and arranged in a plurality of stages.
20d and 121d reliably seal, and no liquid leaks to the external space beyond the outside air seal portions 120d and 121d. Therefore, all of the remaining liquid is supplied to the gas-liquid introduction hole 1
1c can be guided to the container body 2 through the gas-liquid introduction path 14.

The outer outside air seal portion 121d forms an expanding skirt shape toward the inner side of the small diameter cylinder 11 and is slidably in contact with the inner surface of the small diameter cylinder 11, and the inner outside air seal portion 120d is located outside the small diameter cylinder 11. It forms a wide skirt toward and slides on the inner surface of the small diameter cylinder 11. Therefore, the above-mentioned liquid leakage prevention performance by the outside air seal portions 120d and 121d can be improved.

The outside air seal portion 121d has a widening angle.
6 to 12 degrees, the length of sliding contact with the inner surface of the small-diameter cylinder 11 is 0.1 to
1.0mm, and the inside / outside air seal part 120d
10 to 16 degrees, sliding contact length with the inner surface of small diameter cylinder 11 is 0.1 to
By being 1.0 mm, both outside air seal portions 120d,
The liquid leakage prevention performance described above by 121d can be further improved.

(B) Outside air seal portion 120 of the plunger 12
d, 121d and residual pressure seal 120e opening structure (FIG. 6) Gas-liquid introduction hole 11 formed in the lower surface of the small diameter cylinder 11
An outside air introducing rib 11d is provided on the front inner surface of c, and a residual pressure introducing rib 11e is provided on the rear inner surface of the gas-liquid introducing hole 11c.

Then, the outside air seal portion 1 of the plunger 12
20d and 121d are pushed open from the inner surface of the small-diameter cylinder 11 by the outside-air introducing rib 11d of the small-diameter cylinder 11 when the trigger 8 is pulled in the process of rotating the trigger 8, and the external-air introduction path along the inner surface of the small-diameter cylinder 11 is provided. Can be communicated with the gas-liquid introduction hole 11c of the small diameter cylinder 11. As a result, in the pressurization process of the plunger pump 6, outside air can be introduced into the container body 2 so as to release the negative pressure in the upper space inside the container body in the liquid suction process preceding this.

Further, the residual pressure seal portion 12 of the plunger 12
0e is a rib 11e for introducing the residual pressure of the small diameter cylinder 11 when the trigger 8 is pulled out in the process of rotating the trigger 8.
Is pushed open from the inner surface of the small-diameter cylinder 11 and the residual pressure introduction path along the inner surface of the small-diameter cylinder 11 is opened by the small-diameter cylinder 1.
It is possible to communicate with one gas-liquid introduction hole 11c. This allows
At the end of the pressurizing process of the plunger pump 6, the residual pressure in the small diameter cylinder 11 can be removed so as to stop the ejection of the liquid substance started by the movement of the plunger 12 by the predetermined liquid pressure in the small diameter cylinder 11.

Therefore, in the spray container 1, this
The structure of (B) has the following effects. While pulling the trigger 8 (before the residual pressure is removed), the outside air seal portions 120d, 121 of the plunger 12 are pulled out.
An outside air introducing rib 11d for opening the outside air introduction path by pushing d from the inside of the small diameter cylinder 11 is provided on the inside of the small diameter cylinder 11. Therefore, when the trigger container is tilted and used, air replacement is performed at the same time when the trigger 8 is pulled, and when the trigger 8 is completely pulled, the outside air introduction path is closed, so there is no liquid leakage and air replacement is ensured. Is done.

With the trigger 8 pulled out, the residual pressure seal portion 120e of the plunger 12 is pushed open from the inner surface of the small diameter cylinder 11 to open the residual pressure introduction path.
1e is provided on the inner surface of the small diameter cylinder 11. Therefore, even if the internal pressure of the cylinder 11 is high because of the pressure-accumulation type spray container 1, the residual pressure seal portion 120e of the plunger 12 is positively pushed open by the residual pressure introducing rib 11e. Therefore, the operation of introducing the residual pressure into the container body 2 is ensured.

(C) Structure for equalizing the ejection amount from the nozzle portion 13c of the large diameter cylinder 13 At the inner edge of the opening of the cylinder portion 13b of the large diameter cylinder 13,
A plunger stopper 13i for restricting the movement of the plunger 12 (sub plunger 121) is provided. The plunger stopper 13i is a plunger 1 for ejecting a liquid material.
2 depending on the relative movement with respect to the large-diameter cylinder 13, the residual pressure seal portion 120 e provided on the main plunger 120 is moved out of the opening operation position of the residual pressure introduction path (the small diameter cylinder
(A position not reaching the residual pressure introducing rib 11e). Specifically, the movement of the plunger 12 is restricted by abutting the large-diameter seal portion 121b of the sub-plunger 121 with the above-described plunger stopper 13i.

Therefore, in the spray container 1, this
The configuration of (C) has the following effects. When the trigger 8 is pulled to eject the liquid substance, if the trigger 8 is pulled quickly, the hydraulic pressure in the cylinders 11 and 13 rises more than necessary, but the relative stroke of the plunger 12 with respect to the large diameter cylinder 13 is the plunger stopper 13i.
It is regulated and fixed. The plunger stroke regulated by the plunger stopper 13i holds the residual pressure seal portion 120e of the plunger 12 outside the opening operation position of the residual pressure introduction path with respect to the relative movement of the plunger 12 with respect to the large diameter cylinder 13. .

Therefore, regardless of the pulling speed of the trigger 8, it is possible to prevent the residual pressure seal portion 120e of the plunger 12 from opening the residual pressure introduction path at an early stage.
To avoid early removal of residual pressure in the chamber. This prevents the ejection of the liquid material from being stopped early, prevents the ejection amount from decreasing from the start of ejection, and stabilizes the ejection amount.
