When in use, the container 1 is held in the hand and the injection valve 2 is pressed down with the index finger of the other hand to inject the contents.

Further, as other examples of conventional aerosol products, for example, Publication of Utility Model Publication No. 48-2742 and Publication of Utility Model Publication No. 47-
There is one that has a grip part as shown in Japanese Patent No. 18580. Both of these types use a container equipped with an injection valve at the upper end, which is used in an upright position, and is provided with a grip portion extending laterally from the upper end of the container. A long lever is pivotally supported in the center along the grip,
And the tip is in contact with the injection valve. When in use, by grasping the grip and operating the lever, the injection valve is pushed in a lever-like manner using the shaft support as a fulcrum to inject water.

[Problems to be Solved by the Invention] Conventional aerosol products have the problem that if the container 1 is large, it is difficult to hold in the hand and is heavy, making it difficult to physically manipulate.

An object of the present invention is to provide an aerosol product that can be easily operated, whether it is a small aerosol product or a large aerosol product.

In addition, with conventional aerosol products equipped with a grip, the moment due to the weight of the container is applied to the operating hand, making it difficult to operate, and the injection valve is operated using a long lever, making detailed injection work difficult. There is a problem.

[Means for Solving the Problems] The aerosol product of the present invention is a bottomed cylindrical aerosol with an injection valve in the center of the mouth, which is held in an inverted state when injected in a substantially horizontal direction. a container, a grip portion attached to the mouth of the aerosol container, located below the aerosol container in an inverted state, and within a space substantially defined by an extension of a side wall of the container; and a grip portion attached to the mouth of the aerosol container; a trigger for opening the injection valve, which is hinge-coupled to the part and directly connected to the injection valve, and is provided at a part where a finger other than the thumb of the hand holding the grip part touches, and the trigger is connected to the injection valve. It is characterized by having injection holes on the front.

Further, it is preferable that the gripping portion includes a protective cover that can be moved between a position where the trigger is covered and protected and a position where the trigger is exposed and ready for use.

Furthermore, it is preferable that a part of the holding part constitutes the protective cover.

[Function] In the aerosol product of the present invention, the aerosol product can be supported by holding the grip, so even if the container is large, it can be easily held in the hand. Also, even if it is heavy, it will not be difficult to handle. Furthermore, since the trigger can be operated while holding the grip, spraying operations can be performed extremely easily.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Fig. 10 is an explanatory diagram of the configuration of the aerosol product C shown in Fig. 9, and Figs. 2 is an injection valve provided at the center of the mouth of the aerosol container 1, 3 is a grip portion, and 4 is a trigger for opening the injection valve 2. This aerosol product A basically has a configuration in which the aerosol container 1 is attached to the upper end of the grip part 3 in an inverted state (with the injection valve 2 facing downward, the same applies hereinafter).

The aerosol container 1 is a metal pressure-resistant container made of aluminum, tinplate, or the like, and an aerosol content such as a glass cleaner, hair spray, or aerosol paint 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 is tilted, and can inject the liquid contained therein. For example, in the former type of direct-push type injection valve, as shown in FIG. In the latter type of tilting type injection valve, when the stem 21 is pushed down in the direction of arrow F as shown in FIG. One in which the hole 24 and the valve chamber 23 communicate with each other is adopted.

The gripping part 3 is made of synthetic resin and has a shape similar to the gripping part of a pistol, and has a fitting part 31 at its upper end that fits and fixes the mouth part 11 of the aerosol container 1. In addition, a cavity 33 is formed in a portion above the center of the grip portion 3 and is open at the front. The gripping portion 3 is not particularly limited as long as it has a shape that is easy to hold by hand, and various shapes can be adopted, and the presence or absence of ribs can be freely selected. This grip part 3
As a result, the mouth portion of the aerosol container 1 is firmly fitted into the fitting portion 31, 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 integrally connected to the grip part 3 by a thin hinge part 41 continuous to the fitting part 31. It is inserted into the cavity 33 formed in the grip part 3 while keeping an appropriate gap, and when the index finger of the hand gripping the grip part 3 is placed on the front surface and pulled, the hinge part 41 becomes the fulcrum. The trigger 4 is configured to swing in the direction of arrow F. The trigger 4 is also provided with a fitting hole 42 at its upper end for fitting the tip of the injection valve 2, and an injection hole 43 on its front surface, and the fitting hole 42 and injection hole 43 are connected to each other. The space between them is communicated by an internal passage 44. Since the bottom of the fitting hole 42 is in contact with the tip end surface of the injection valve 2, when the trigger 4 is moved in the direction of arrow F, if the injection valve 2 is a direct push type, it will move in the axial direction. The valve opens when pushed, and if it is a tilting type, it opens when it is tilted diagonally. With this configuration, the aerosol content can be sprayed by moving the trigger 4 with the index finger. Note that the hinge portion 41 which is the fulcrum
Since the distance from the opening to the point where the index finger is applied is longer than the distance between the hinge portion 41 and the injection valve 2, the valve can be opened with a light operating force using the principle of leverage.

In the configuration of the present embodiment described above, the fitting portion 3 of the gripping portion 3
If the dimensions of the fitting hole 42 of the grip part 3 and trigger 4 are matched to the mouth part 11 of the aerosol container 1 and the injection valve 2, the integrally molded part of the grip part 3 and trigger 4 can be fitted into an aerosol product with a conventional configuration. The aerosol product A of the present invention can be constituted by simply
It is also effective in reducing manufacturing costs. Furthermore, in the aerosol product A of this embodiment, if the protective shelf 5 is attached as shown in FIG. 5, the trigger 4 may be moved unexpectedly before use, causing the aerosol content to be sprayed. Accidents can be prevented. Such a protective shelf 5 is not limited to the form shown in the figure, 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, the notches 51 at both ends of the protective shelf 5 are formed. , 51, or may be detachably attached using an appropriate dovetail groove.

In the aerosol product A of this embodiment, 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, and the trigger 4 can be moved simply by using the index finger. Since the aerosol content can be sprayed, it has the advantage of being very easy to operate.

Next, the aerosol product B of the second example was added to the
This will be explained based on FIG.

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 of a telescoping type, and the inner member 34 is molded integrally 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 designed to slide up and down with respect to the inner member 34. The sliding movement is caused by two protrusions 3 formed on the inner member 34.
6 and a slit 37 formed in the outer member 35
Furthermore, the width of the slit 37 is narrow at both upper and lower ends so that a light frictional resistance is generated in the sliding movement of the projection 36. Therefore, in the state in which the outer member 35 is pulled down (see FIG. 6) and in the state in which the outer member 35 is pushed up (see FIG. 8), the outer member 35 does not slide unless an artificial force is applied.

The aerosol product B of this embodiment 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. When the outer member 35 is pushed up (see FIG. 8), the height of the gripping portion 3 is reduced to approximately 1/2, making the entire structure more compact. Also, in this state, the trigger 4 is surrounded by the outer member 35, so
It is possible to reliably prevent the trigger 4 from moving unexpectedly.

Next, the aerosol product C of the third example was
This will be explained based on FIG.

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 grip portion 3 is configured such that the fitting portion 31 and the 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 shaping the inner peripheral part of the cylindrical main body 38 to be thick, and has a groove 382 on the inner peripheral surface.
was formed. 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 portion 311 is formed from a peripheral wall 312 and a protrusion 313 formed on the outer periphery of the peripheral wall 312.
The fitting portion 381 of the main body 38 is fixed by firmly inserting both ends thereof into the fitting portion 311.

A notch 39 is formed at one end of the main body 38, and the notch 39 partially exposes the trigger 4 in the mounted state shown in FIG.

In the aerosol product C of this embodiment, the main body 38 of the gripping part 3 is attached with the notch 39 facing up (as shown in FIG. 9), and is gripped and used, and when not in use, the notch 39 is turned down. It is used by attaching it (as shown in Figure 10). When the body 38 is attached as shown in FIG. 10, the trigger 4 is surrounded by it, so that the trigger 4 can be accidentally
Accidents in which the system activates are prevented.

All of the three embodiments described above are suitable for large-sized aerosol 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 particularly convenient for types that vaporize and blow away liquefied gas.

In each of the above-mentioned embodiments, 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 or 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. he,
It has high utility value.
