Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an aerosol device. More specifically, the present invention relates to an aerosol device that is mainly used facing downward and is easy to hold and operate.

[Prior Art] A conventional aerosol device is generally constructed as shown in FIG. That is, a valve stem 2 is provided at one end of the aerosol can 1, and a push button 3 is attached to the valve stem 2. The valve stem 2 is connected to a valve provided inside the aerosol can 1, and when the valve stem 2 is pushed down, the valve opens and the aerosol contents are injected to the outside. Therefore, when using this aerosol device, the aerosol contents cannot be sprayed unless the user holds the aerosol can 1 with the thumb or middle finger and presses down the push button 3 with the index finger.

[Problems to be solved by the invention] In conventional aerosol devices, for example, when spraying the aerosol contents downward, the wrist of the hand holding the aerosol can 1 is often bent. When the wrist is bent, the range in which the index finger can be comfortably bent becomes narrower, making it difficult to push down the push button 3. Also, if you pay attention to your index finger when operating the aerosol can 1, it becomes easier to drop it. This is especially true when the diameter of the aerosol can 1 is small, since it is difficult to apply pressure to the thumb and middle finger. For this reason, conventional aerosols are relatively difficult to operate when used by spraying the aerosol contents downward. It is especially difficult to perform delicate tasks such as spraying medicine into a narrow area, such as when applying medicine to an affected area, or writing letters or drawings with paint.

In view of the above circumstances, it is an object of the present invention to provide an aerosol device which is mainly used facing downward, which allows easy injection operation and which can be held securely in the hand to prevent the aerosol can from falling off. purpose.

[Means for Solving the Problems] The aerosol device of the present invention comprises: (a) a relatively slender aerosol can, an aerosol valve provided at the center of one end of the aerosol can that is mainly used downward, and the aerosol can; It consists of a relatively long spout attached to the stem of the valve, a cap attached to the outer periphery of the one end of the aerosol can, and a pair of lever members connected to the cap at a hinge part and facing each other so as to sandwich the spout, (b) The pair of lever members each include a finger pressing portion extending along the side wall of the aerosol can from a hinge portion forming a fulcrum of the lever member and forming a point of force of the lever member, and a finger pushing portion extending from the hinge portion toward the stem. (c) said finger press is longer than the stem press, and said aerosol can is held in place by a pencil; It is characterized by a length that makes it easy to hold it between the thumb and index finger when holding it.

Furthermore, "horizontal" in the scope of the utility model registration request
refers to the direction perpendicular to the central axis of the aerosol can.

[Operation] In the aerosol device of the present invention, by pinching and pushing the lever member between the thumb and forefinger, the valve stem can be moved and the aerosol contents can be ejected. Therefore, the valve can be opened easily by holding the aerosol device as if holding a pencil. In addition, since the spout and finger press are relatively long, if you hold it as described above, you can support the aerosol can between the tips of your thumb and index finger and the base of those fingers. You can now hold the aerosol device securely without the risk of it falling off, and you can move the aerosol device just as you move your wrist, giving you greater freedom of movement and allowing for advanced uses such as writing. becomes.

[Example] Next, an example of the present invention will be described based on the drawings.

FIG. 1 is a cross-sectional front view of essential parts of an aerosol device A according to an embodiment of the present invention, FIG. 2 is an explanatory diagram of the operating state of the aerosol device A shown in FIG. 1, and FIG.
The figure is a plan view of the main part of the aerosol device A shown in FIG. 1, FIGS. 4 and 5 are sectional views of the main part showing a modification example of the lever member 6, and FIG. 6 is an explanatory diagram of the use of the aerosol device A. It is.

In Figs. 1 to 3, 1 is an aerosol can, 2 is a valve stem, 4 is a spout, 5 is a cap, and 6 is a lever member. The aerosol can 1 is a slender one with a relatively small diameter, and is a pressure-resistant metal container made of aluminum, tinplate, or the like. Inside part 1, aerosol contents such as glass cleaner, hair spray, aerosol paint, etc. are packed together with a propellant. valve stem 2
is connected to a valve (not shown) provided inside the aerosol can 1 for an aerosol that is mainly used downward, and a portion projects outward from the center of one end of the aerosol can 1. The valve stem 2 is of a known type which can open the valve when pushed down. The spout 4 is fitted into the valve stem 2 and has an annular shoulder 7 formed at its lower end. A cylindrical cap 5 is firmly fitted to the outer periphery of one end of the aerosol can 1, and a lever member 6 is connected and attached to the cap 5 by a hinge portion 8. The lever member 6 has a substantially L-shape, and includes a finger push portion 9 that extends from the hinge portion 8 along the stem axis direction (that is, upward in the figure) and a finger push portion 9 that extends from the hinge portion 8 toward the valve stem 2. A pair of stem pressing parts 10 are arranged symmetrically around the valve stem 2. In other words, in relation to lever action, the hinge section 8 serves as a "fulcrum" and the finger pressing section 9 serves as a "point of force".
, the stem depressing portion 10 each forms a "point of action". The spout 4, cap 5, lever member 6 and hinge portion 8 are preferably made of a synthetic resin material having some flexibility, such as polyethylene, polypropylene, polyamide, polyacetal. The hinge part 8 made of such a material is a thin member continuously formed between the cap 5 and the lever member 6, and has a relatively narrow width in order to improve flexibility. . In addition, the stem pressing part 10 has a stepped part formed at its tip, and the spout 4
It is adapted to be in contact with the upper surface of an annular shoulder 7 provided at the lower end of.

In the aerosol device A of the present invention, the hinge portion 8 is made rotatable by inserting the round recess 61 provided on the lever member into the round recess 81 provided on the cap 5, as shown in FIG. It may also be a configuration. Further, the stem pressing portion 10 of the lever member 6
and the lower end of the spout 4 may be integrally connected by a thin wall portion 11 as shown in FIG.

As shown in FIG. 2, in the aerosol device A configured as described above, when the lever member 6 is pinched with a finger or the like and the tip of the finger pressing portion 9 is narrowed, the stem pressing portion 1
0 pushes down the valve stem 2 through the spout 4, thereby opening the valve connected to the valve stem 2. Therefore, the aerosol device A of the present invention can be held in the hand as if holding a pencil, as shown in Fig. 6, and if a slight force is applied to the fingertips of the thumb and index finger while holding it, the aerosol can be released. The contents can be squirted out. In addition, since it can be held in this way, it can be used for ejecting medicine in the form of a foam into an affected area, for ejecting it close to an object and ejecting it in a narrow area, or for writing letters with paint or markers. It is also suitable for uses that require complex movements.

In the above embodiment, the valve stem 2 is of the push-down type, but it can also be of the tilting type, which can open the valve housed inside the aerosol can 1 by pushing it sideways and tilting it slightly. A valve stem may also be used. Although such a case is outside the scope of the present invention, the valve may be opened by directly pushing the spout 4 fitted to the valve stem with the finger pressing portion 9 of the lever member 6.

In the aerosol device of the present invention, as the aerosol contents, in addition to liquid contents, foam-like contents, cream-like contents, paste-like contents, etc. can be used.

[Effect of idea]

The aerosol device of the present invention uses a relatively slender aerosol can, which is easy to hold in the hand and there is no risk of dropping it.Furthermore, the valve can be opened by simply applying a little force to the thumb and forefinger of the hand holding the aerosol can. This makes the valve opening operation very easy.
In addition, since the aerosol device can be moved with the movement of the wrist, it can also be used for writing, for example.
