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 equipped with a protector mechanism to prevent a valve from being operated without permission on a store display shelf or the like.

[Prior Art] Conventional aerosol devices are designed to prevent customers from operating the valve without permission during the distribution process, especially on store display shelves where they are displayed in an exposed manner, and to prevent the valve button from being pressed by mistake. As such, the pushbuttons are carefully packaged to protect them.

[Problems to be solved by the invention] Merely packaging tightly is not sufficient to protect the push button.

Especially these days, to make pushbutton operation easier,
Attempts have been made to create aerosol devices with larger push buttons or lever principles that allow the valve to be operated with a weaker pushing force. Extremely difficult to package.

It is an object of the present invention to provide an aerosol device that is easy to operate a push button, has sufficient protection of the push button during the distribution process, and can be sufficiently protected during use.

[Means for Solving the Problems] The aerosol device of the present invention is an aerosol device having a pressure-resistant container and an injection valve provided at the center of the upper end of the container, which is fitted into the stem of the injection valve. a push button which is fixed to the upper end of the container, extends to a higher position than the push button, and has openings on at least the spout side and the push part side, respectively; The front and rear ends of the fixed protector are rotatably connected to each other near the front and rear of the fixed protector, with a straight line connecting the front and rear ends serving as a rotational axis, so as to cover each opening in a freely openable and closable manner. and two spherical arc-shaped movable protectors, and the push button is provided with a connecting piece extending from the nozzle side thereof and integrally connected to the fixed protector and having a hinge part in the middle, The two movable protectors are configured so that when one of them is opened or closed, the other can be opened or closed at the same time.

In the aerosol device, the front ends and rear ends of the two movable protectors are rotatably connected to each other, and a portion somewhat distant from the front and rear ends of each movable protector is connected to the front and rear ends of the fixed protector. Each may be rotatably and movably supported in the left-right direction near the rear.

Alternatively, the front ends and rear ends of the two movable protectors are connected to each other so as to be freely rotatable and movable in the left-right direction, and a portion somewhat distant from the front end and rear end of each movable protector is connected to the front end of the fixed protector. It may be rotatably supported near the portion and rear portion, respectively.

In addition, "spherical arc shape" as used in the claims for utility model registration refers to the so-called watermelon skin shape, that is, two spherical convex curved surfaces that intersect with each other, as in the case of the movable protector shown in FIGS. 2 and 4, for example. A shape that looks like a section cut out on a plane.

[Function] When the two openings are covered by the movable protector, the push button cannot be pressed arbitrarily from the outside, and the aerosol device can be particularly protected during the distribution process.

Since the fixed protector extends to a higher position than the push button, the push button is protected even when the movable protector is open.

By pressing down on one side of the movable protector, for example the right movable protector, with your index finger,
Both movable protectors open to allow push button operation, and the front side of the nozzle can also be opened. Therefore, operations such as spraying can be easily performed with one hand.

The push button constitutes a lever with the hinge part as a fulcrum, the push part as a point of force, and the fitting part with the stem as a point of action, so that the injection valve can be operated smoothly with a light operation of the push part.

When the front and rear ends of the movable protectors are rotatably connected to each other, and the vicinity of the front and rear ends of the movable protector is rotatably supported near the front and rear of the fixed protector, one When the movable protector is opened and closed in the vertical direction, its front and rear ends also move in the vertical direction around the support point. As a result, the front and rear ends of the other movable protector are also moved in the vertical direction, and are simultaneously opened and closed about the support point thereof.

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

FIG. 9 is a front view showing a reference example of the device of the present invention, FIG. 10 is a plan view of the device shown in FIG.
1 to 13 are a front view, a plan view, and a partially sectional side view showing the device shown in FIG. 9 in an open state, respectively.

In FIGS. 1 to 3, 1 is a cylindrical pressure-resistant container. An injection valve 3 is provided at the center of the upper end of the container 1 by a mounting cap 2, and a stem 4 of the injection valve 3 protrudes from the center of the upper end of the container 1.

A push button 7 having a nozzle 6 communicating with the stem 4 through a hole 5 is fitted into the stem 4 . The push button 7 is integrally provided with a relatively large push part 8 extending rearward, on which a finger can be placed.

A hemispherical fixed protector 10 having a groove 9 extending in the front-rear direction is fixed to the upper end of the container 1 and rises to a higher position than the push button. Therefore, the pushbutton 7 is located above, on the nozzle 6 side (hereinafter referred to as the front) and on the opposite side (hereinafter referred to as the rear).
is open on three sides.

The groove 9 of the fixed protector 10 is covered by two movable protectors 11, 12 which can substantially hide the open surface thereof. The two movable protectors 11 and 12 each have a so-called watermelon skin shape, that is, a shape like a portion of a spherical convex curved surface cut out by two planes that intersect with each other.

Front ends 1 of each of the movable protectors 11 and 12
Fixed protector 10 near 3 and rear end 14
It is rotatably connected to the front and rear parts of the body about a horizontal axis of about 45 to 60 degrees.

In the movable protectors 11 and 12 shown in FIG. 4, the respective front ends 13 and rear ends 14 are connected to each other by a thin hinge portion 15. Furthermore, pins 16 and 17 are protruded from the inner surfaces of the movable protectors 11 and 12 at locations somewhat distant from the front and rear ends 13 and 14.

On the other hand, guide grooves 18 as shown in FIG. 5 are formed in the horizontal direction on the front and rear outer sides of the fixed protector 10, respectively. The guide groove 18 is provided with an insertion groove 19 having a somewhat narrow width, and the insertion groove 19 is inserted into the frame portion 1 of the fixed protector 10, for example.
It continues to the end face 10b of 0a.

Pins 16, 1 of the movable protectors 11, 12
7 into the guide grooves 18 through the insertion grooves 19 on both sides of the fixed protector 10, as shown in FIG.
1, 12 can be connected to the fixed protector 10.

In that case, the pins 16 and 17 are rotatable relative to the guide groove 18 and are movable in the left-right direction.

Therefore, from the closed state shown in FIG. 2, one of the movable protectors 11 and 12, for example, the right movable protector 12, is rotated downward (in the direction of arrow A in FIGS. 2 and 7) to open the right opening. When opened, the front end 13 (the same goes for the rear end 14) of the movable protector 12 moves upward (in the direction of arrow B) using the pin 17 as a fulcrum, as shown in FIG. Since the movable protector 13 also moves upward with the pin 16 as a fulcrum, the movable protector 11 also opens and the entire push button 7 is exposed.
Further, the opening can be closed by the operation opposite to the above.

In addition, in the above operation, the pins 16 and 17 can freely move in the horizontal direction, so the movable protectors 11 and 12 rotate smoothly along the surface of the fixed protector 10 centering on the hinge portion 15.

In order to stably hold the movable protectors 11 and 12 in the closed and open positions, respectively, grooves formed on the outer peripheral surface of the fixed protector 10 and protrusions formed on the movable protectors 11 and 12 (none of which are shown) are used. The pins 16 and 17 may be elastically engaged with each other, or a narrow portion (not shown) may be formed in the guide groove 18 so that the pins 16 and 17 may be elastically engaged with each other. You can. Further, it is preferable to form finger hooks 20 on the outer peripheries of the lower ends of the movable protectors 11 and 12, respectively.

In the embodiment shown in FIGS. 5 to 7, the movable protector 1
The front and rear ends 13 and 14 of 1 and 12 are hinged together, and the pins 16 and 1 are provided near the front and rear ends 13 and 14.
The movable protectors 11 and 12 of the present invention are configured to slide within the guide groove 18.
The structure for connecting the fixed protector 10 to the fixed protector 10 is not limited to such a case.

For example, as shown in FIG.
1 and 12 are pivotally connected to the fixed protector 10 by pins 16a and 17a provided near the front and rear ends 13 and 14, and the respective front ends 13 and rear ends (the same as in the case of the front ends, so (not shown) by pin 21 and guide 22, etc.
They may be connected to each other so as to be rotatable and movable in the left and right directions. In addition, in the connection structure shown in Fig. 8,
The same effect can be obtained by fixing pinions (not shown) that mesh with the pins 16a and 17a, respectively.

The aerosol device of the present invention employs a large push button 7 and is constructed so that the valve can be operated near the rear end of the container 1 by employing the lever principle.

In the aerosol device shown in FIG. 3, a conical cover portion 23 extends from the front upper edge of the fixed protector 10;
A tongue-like connecting piece 24 extending from the cover part 23 is provided so as to extend toward the center of the container 1.

The connecting piece 24 has a bendable hinge part 25 in the middle, and the free end 24a of the connecting piece 24
is fixed to the front side of the push button 7.

Note that on the lower side of the portion of the cover portion 23 adjacent to the hinge portion 25, there is an internal support frame 27 that can be fitted onto, for example, the connecting portion 26 of the mounting cap 2 and the container 1, in order to ensure a fulcrum action. It is provided. The internal support frame 27 has an annular shape with a cutout on the rear side.

The fixed protector 10, cover portion 23, internal support frame 27, connecting piece 24, and push button 7 are made of, for example, polyethylene, polypropylene, nylon,
It can be integrally molded from synthetic resin such as polyacetal or styrene. However, the push button 7 and the connecting piece 2
4 may be separated from each other at, for example, the hinge portion 25, the whole may be constructed as two parts, and these may be rotatably connected to each other by a hinge member or the like.

With the above configuration, the operation of the push button 7 is not obstructed by the fixed protector 10, etc., and the hinge part 25, the push part 8, and the fitting part with the stem 4 are used as the fulcrum, the point of force, and the point of action, respectively. The valve is constructed with a lever that allows the valve to be operated with light force.

Note that, like the fixed protector 10, the movable protectors 11 and 12 can also be manufactured from synthetic resin such as polyethylene, polypropylene, nylon, polyacetal, and styrene.

Furthermore, normally the fixed protector 10 can be fixed to the connection part 26 of the container 1 using the internal support frame 27, but it may be attached by other means.

The shape of the fixed protector 10 in the present invention is as follows:
The protector is not limited to the hemispherical shape, and may have other shapes, such as a fixed protector 10a made of a cylindrical member with a spherical upper part as shown in FIGS. 9 to 13, for example. Furthermore, the shape of the movable protector can be changed in various ways.

9 to 13 show reference examples and do not fall within the scope of the present invention in that the push button protrudes higher than the fixed protector, but the shapes of the movable protectors 11, 12 and the fixed protector 10a are similar to the present invention. It is included in the idea.

In the apparatus shown in FIGS. 9 to 13, the movable protectors 11 and 12 are lowered below their rotational fulcrums, which has the advantage that the open surface can be widened and the push button 7 can be easily operated. .

The aerosol device configured as described above is rotated so that the movable protectors 11 and 12 are closed as shown in FIG. 2 during the distribution process, etc.
The upper end of the container 1 is covered in a dome shape.

When a user uses the aerosol device, he or she rotates one of the movable protectors 11, 12, for example, the right movable protector 12, approximately 60 degrees in the direction of arrow A in FIG. Simply open it to expose the area around the push button 7, and press the push part 8 in that state. After use, the movable protectors 11 and 12 may be closed by reversing the procedure described above.

In the present invention, the fixed protector 10 does not necessarily have to be open all the way to its top, but only needs to be open at least on the front side of the nozzle 6 and in the vicinity of the pusher 8. However, it is preferable if the fixed protector 10 is opened to the upper side as shown in FIG. 1, since the push button 7 can be easily operated. Further, by making the push part 8 project backward or by applying the above-mentioned lever principle, the push button 7 can be operated even more easily.

Furthermore, when the pushing part 8 is made to protrude rearward, there is a relatively high possibility that it will be pushed by mistake. This can be sufficiently prevented by protecting the upper end of the .

It is preferable to make the movable protector transparent because it allows the user to see inside, makes it easier to understand the inside, and makes it less likely to be misused.

The aerosol device of the present invention does not have the disadvantages of eliminating the cap or the troublesome opening operation compared to conventional protection methods in which the cap is detachably provided. However, if necessary, the movable protectors 11 and 12 may be configured to be detachably attached to the upper end of the fixed protector 10. In that case, the user should purchase the aerosol device and
The movable protector may be discarded and used.

[Effect of the invention] In the aerosol device of the invention, the push button is protected from being pressed without permission during the distribution process. Moreover, the injection valve can be opened and closed with one hand.
