Abstract

PROBLEM TO BE SOLVED: To provide an excellent periodical injection type insecticide container, which can jet an insecticide after a specified period of time from the setting of it by placing in a sealed room, and at the same time, can be set by an extremely simple operation, and has a high safety property. SOLUTION: In an operation chamber A being partitioned on the top of an aerosol container body 2 wherein a stem 8, of which the valve is opened by tilting, is provided, a discharging nozzle 3 being fitted on the stem is tiltably projected. Then, in the operation chamber, a spring member 4 to which a plate spring 24 is integrally connected, is provided, and a pressing plate member 5 of which the pressing plate 30 at the upper end, is projected through a guide groove on the top plate of the operation chamber, is rotatably fitted on the spring member. When the pressing plate is pushed backward while resisting the elastic force of the plate spring, and at the same time, is turned into the operation chamber from a window hole 33 being connected to the rear part of the guide groove, the pressing plate being advanced by the plate spring, transfers while being speed-reduced by a reduction gear mechanism 6 in the operation chamber A, and at the same time, the nozzle is pressed and tilted by the tilted pressing plate.

The bearing 25 is configured such that the left side surface thereof is integrally connected to the right side surface of the slide plate 23, and the rear surface thereof is integrally connected to the front surface of the base portion 24a. The guide of the slide plate 23 to the front side is not limited to the rail, and other methods may be adopted.

The pressing plate member 5 is a member for pressing the nozzle 3 in order to eject the pesticide, and the bearing 25 is used.
The operation chamber top plate 11 from the tip of the shaft core 28 that is rotatably fitted inside
A pressing plate 30 is provided so as to project above the top plate 11 via a guide groove 29 formed in the top plate 11.

In this embodiment, as shown in FIG. 5, a rod-shaped support portion 31 is erected above the tip of a cylindrical shaft core 28 that is rotatably fitted to the bearing 25, and a wide flat plate is provided at the tip thereof. A pressing plate 30 having a shape is extended and configured. Also, the pressing plate 30
A curved concave portion 32 that fits the rear surface of the nozzle 3 is provided on the front surface of the. Further, a guide groove 29 running forward and backward is provided at a predetermined position on the left side of the nozzle of the top plate 11, and further, a semicircular shape of the pressing plate 30 at the rear end of the guide groove 29 allows the downward movement of the top plate 11 below. A window hole 33 having a size is extended.

Then, the shaft core 28 is fitted in the bearing 25, the rod-shaped support portion 31 is fitted in the front portion of the guide groove 29, and the pressing plate 30 is mounted so as to project above the top plate 11. Therefore, in this state, the leaf spring 24 is not elastically deformed, and the pressing plate 30 is positioned in the front part of the guide groove 29 so that it can be pushed back to the rear.

The reduction gear mechanism 6 has a pinion 34 at one end which meshes with the rack gear G, and is provided with a plurality of gears interlocking with the pinion to reduce the movement of the slide plate 23. In this embodiment, A large first large diameter gear 35 coaxially fixed to the pinion 34, a small first small diameter gear 36 meshing with the gear 35, and a large second large diameter gear coaxially fixed to the gear 36. 37, a small-diameter second small-diameter gear 38 that meshes with the gear 37, and a large-diameter third large-diameter gear 39 coaxially fixed to the gear 38.

The deceleration gear mechanism 6 is not limited to that of this embodiment, and any device that decelerates by applying a load to the rack gear by selecting a gear ratio by interlocking a plurality of gears can be used. it can.

When the container 1 constructed as described above is used, the pressing plate 30 is pushed back from the state of FIG. 2 against the elastic force of the plate spring 24, and then the window is opened as shown in FIG. When the pressing plate 30 is moved into the operation chamber A by rotating the top plate 11 in the hole 33 downward, the slide plate 23 is guided by the rail by the elastic restoring force of the plate spring 24 and moves forward. The advancing pressing plate 30 presses and tilts the nozzle 3 as shown in FIG. 4, and the stem 8 tilts accordingly, and the insecticide in the container body 2 is ejected from the tip of the pouring nozzle 3 via the stem 8.

After rotating the pressing plate 30, the slide plate 23
The time until the nozzle 3 is moved forward and the nozzle 3 is tilted is sufficient for the setter to get out of the closed chamber. For example, depending on the size of the room and other factors, 5
The time is selected from the range of about 30 seconds as needed, and is adjusted by the gear ratio of the reduction gear mechanism, the strength of the leaf spring, and the like. However, this time is not limited to the above range.

Further, it is preferable that each of the above-mentioned members is formed mainly of synthetic resin, and if necessary, metal or elastomer is used in combination.

[0025]

As described above, in the container of the present invention, the pouring nozzle fitted to the upper end of the stem of the container body is provided in the operation chamber defined above the aerosol container body in which the tilt-open valve type stem is projected. In addition to projecting so that it can be tilted, its upper end faces the jet outlet in the center of the operation chamber top plate so that it can be ejected, and it is guided integrally in the operation chamber back and forth and is integrated with a slide plate with a rack gear engraved on one side. A spring member is provided in which a spring is extended, and a bearing having a tip opening parallel to the slide plate is continuously provided.Furthermore, from a tip of a shaft core rotatably fitted in the bearing, through a guide groove of the operation chamber top plate. A pressing plate member formed by projecting a pressing plate, and a reduction gear mechanism that reduces the movement of the slide plate in conjunction with the rack gear, and the pressing plate is rearward against the elastic force of the plate spring. Window that is connected to the rear of the guide groove When the slide plate is moved further into the operation room, the slide plate that moves forward by the plate spring moves while being decelerated by the reduction gear mechanism, and the nozzle is pressed and tilted by the tilted pressing plate. It is possible to provide a sufficient time from the spraying of the insecticide to the spraying of the insecticide. Therefore, there is no fear that the setter inhales the insecticide. The effect is simple and safe.

Further, when not in use, the leaf spring is in a stable state with no elastic deformation, and since the leaf spring is not always loaded during storage and transportation up to the consumer, the durability is also excellent. It is something to demonstrate.

Further, in the container of the second aspect of the present invention, the leaf spring easily urges the slide plate straight forward, the slide plate guided by the rail or the like advances more smoothly, and the slide plate and the bearing are integrated together. Since it can be formed in the same manner, it also exhibits the effect of being convenient in manufacturing.

Further, the container of the third aspect of the present invention can also exert the effect that the assembling operation can be performed more easily.
