2) is configured so that it can be installed with the camera facing downward (the same applies hereafter).

The aerosol container (1) is a metal pressure-resistant container made of aluminum, tinplate, etc., and an aerosol content such as glass cleaner, hair spray, aerosol paint, etc. is filled therein together with a propellant. The injection valve (2) is a known valve that opens when the stem is pushed in the axial direction or tilted so that the axis line is tilted, and the liquid inside is injected. For example, in the case of the former direct-push type injection valve, as shown in FIG.
The valve chamber (23) and the through hole (24) are in communication with each other.As shown in Fig. 4, for the latter tilting type injection valve, the stem (21) is pointed with When pushed down in the direction (F), a gap is created between the rubber gasket (25) and the through hole (24) communicates with the valve chamber (23).

The gripping part (3) is a member made of synthetic resin and having a shape similar to the gripping part of a pistol, and the mouth part (11) of the aerosol container (1) is fitted and fixed to the upper end of the gripping part (3). A fitting part (31) is formed therein, and a cavity (33) opened at the front is formed in a portion above the center of the gripping part (3). Note that this gripping part (3) is not particularly limited as long as it has a shape that is easy to grip by hand, and various shapes can be adopted, and the presence or absence of ribs can be freely selected. The mouth of the aerosol container (1) is firmly fitted into the fitting part (31) by the gripping part (3), and the aerosol container (1) is stably held in an inverted state.

The trigger (4) is a rectangular member made of the same material as the grip part (3), and is connected to the grip part (3) by a thin hinge part (41) connected to the fitting part (31). are connected together. It is inserted into the cavity (33) formed in the grip part (3) with an appropriate gap, and if the index finger of the hand holding the grip part (3) is placed on the front surface and pulled, the The trigger (
4) is adapted to swing in the direction of the arrow ('').The trigger (4) also has a fitting hole (42) at its upper end for fitting the tip of the injection valve (2). , an injection hole (43) is provided on the front surface thereof, and the fitting hole (42)

Such a configuration allows the bird to be −(
By moving 4) with your index finger, you can spray the aerosol content. Note that the distance from the hinge (41), which is the fulcrum, to the point where the index finger is placed can be longer than the distance between the hinge (41) and the injection valve (2), so it can be opened with a light operating force due to the lever principle. It can be done.

In the configuration of this embodiment described above, the fitting part (31) of the grip part (3)
) and the fitting hole (42) of the trigger (4) to match the opening (11) of the aerosol container (1) and the injection valve (2).
The aerosol product (A) of the present invention can be constructed simply by fitting the integrally molded parts of the trigger (3) and the trigger (4), which is also effective in reducing manufacturing costs. Furthermore, in the aerosol product (A) of this example, if a protective shelf (5) is attached as shown in FIG.
It is possible to prevent an accident in which the aerosol content is sprayed due to the trigger (4) being moved unexpectedly before use. Such a protective shelf (5) is not limited to the form shown, but may be a cap-shaped one, or it may be formed integrally with the grip part (3) in advance as shown in the figure, and when used, both ends of the protective shelf (5) may be formed integrally with the grip part (3). It may be removed by tearing it off from the notches (51), (51), or it may be detachably attached using an appropriate dovetail groove.

In the aerosol product (A) of this example, the grip part (3) can be held and supported by the hand as described above, so even if the aerosol container (1) is large, it can be supported easily. 4) The aerosol content can be sprayed by simply moving the forefinger, which provides the advantage of very easy operation.

Next, the aerosol product (B) of the second example will be explained based on FIGS. 6 to 8.

In the figure, an aerosol container (1), an injection valve (2), and a trigger (4) have substantially the same construction as in the first embodiment.

The main body of the gripping part (3) is pre-fitted, and the inner member (34) is integrally molded with the fitting part (31). The outer member (35) is a cylindrical member with a shape that is easy to hold in the hand, and is adapted to slide up and down with respect to the inner member (34). The sliding movement is guided by two protrusions (36) formed on the inner member (34) and a slit (37) formed on the outer member (35). )
The width is narrow at both upper and lower ends of the protrusion (36), so that a light frictional resistance is generated in the sliding movement of the protrusion (36).

Therefore, the outer member (35) is pulled down (6th
(see figure) and in the state where the outer member (35) is pushed up (see Fig. 8), the outer member (35) does not slide unless force is applied artificially.

The aerosol product (B) of this example is used by grasping the grip part (3) with the outer member (35) pulled down, and when not in use, the outer member (35) is pushed up. It is used as follows. Outer part (
35) is pushed up (see Figure 8), the grip part (
3) has a height of about 172 cm, making the entire structure compact.

In addition, in this state, the trigger (4) is connected to the outer member (35).
), it is possible to reliably prevent the trigger (4) from moving unexpectedly.

Next, the aerosol product (C) of the third example was added to the
This will be explained based on the diagram.

In the figure, an aerosol container (1), an injection valve (2), and a trigger (4) have substantially the same construction as in the first embodiment.

The gripping part (3) has a structure in which a fitting part (31) and a main body (38) are separate bodies. The main body (38) is a cylindrical member having a shape that is easy to hold by hand, and both ends are open, and a fitting part (381) is formed at each end. This fitting part (381) is formed by thickly molding the inner peripheral part of the cylindrical main body (38), and has a recess on the inner peripheral surface. 11 (382). On the other hand, a fitted part (311) into which the fitted part (381) can be fitted is provided at the lower part of the fitting part (31). This fitted part (3
11) is formed from a peripheral wall (312) and a protrusion (313) formed on the outer periphery of the peripheral wall (312). Both ends of the fitting portion (381) of the main body (38) are fixed by being firmly inserted into the fitting portion (311).

The main body (38) has a cutout (39) formed at one end, and the cutout (39) partially exposes the riggers 1 to 4 in the installed state shown in FIG. It looks like this.

In the aerosol product (C) of this example, the main body (38) of the grip (3) is attached with the notch (39) facing upward (as shown in Figure 9), and the product is gripped and used. When in use, it is installed with the notch (39) facing down (as shown in Figure 10). As shown in Figure 10, the main body (38
), the trigger (4)
Since the trigger (4) is surrounded, an accident in which the trigger (4) is activated unexpectedly is prevented.

Next, the aerosol product (D) of the fourth example will be explained based on FIG. 11.

In the figure, an aerosol container (1) and an injection valve (2) are shown.
) has substantially the same structure as the first embodiment.

An adapter (6) is attached to the injection valve (2), and the injection hole (61) projects considerably forward from the trigger (4). The grip part (3) has a hollow interior, and a vertically long trigger (4) is attached to the hinge part (
41) so that it can swing freely. A protrusion (46) is formed on the upper surface of this bird (4), and comes into contact with the lower surface of the base of the adapter (6). Therefore, when the trigger (4) is pulled, the injection valve (2) opens and the aerosol content is injected from the adapter (6).

In this embodiment, the trigger (4) is made long, so that it can be pulled not only with the index finger but also with the middle finger, ring finger and little finger. Therefore, it is easy to apply force, and it is particularly suitable for large-sized aerosol products.

All of the four embodiments described above are suitable for large-sized niasol products, such as glass cleaners that use a large amount of aerosol content, hair sprays for commercial use, and the like. However, it is not limited to large aerosol products, but even small aerosol products are easy to use because of their light operation, and are also convenient for types that vaporize liquefied gas and blow it away.

In each of the above-mentioned embodiments, the aerosol container (1) is held in an inverted manner, but a configuration may also be adopted in which the aerosol container (1) is hung under the grip portion (3) in an upright manner. Furthermore, it is preferable that the injection hole (43) provided on the front surface of the trigger (4) protrudes from the front surface, since this prevents the aerosol content liquid to be ejected from adhering to hands and the like.

[Effects of the Invention] The aerosol product of the present invention can be easily handled not only in small aerosol containers but also in aerosol products equipped with large and heavy aerosol containers, thereby preventing worker fatigue. It is highly useful.
