Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to aerosol contents, such as pharmaceuticals, hair supplies, cosmetics, etc., in which the amount used within a prescribed period, such as one day, several days, one week, etc., is limited. The present invention relates to an aerosol container dispensing device capable of using only a predetermined amount.

[0002]

2. Description of the Related Art Conventionally, a fixed-quantity injection valve for constantly determining the injection amount of an aerosol content ejected in one injection is disclosed in Japanese Patent Publication No. 50-11607 and Japanese Patent Publication No. 5-29510. Etc. exist. These conventional metering injection valve mechanisms have the advantage that the amount of aerosol sprayed by a single spraying operation is quantified.

[0003]

However, the amount of daily use is determined, such as for pharmaceuticals and hair tonics.
Within the range of daily usage, aerosol contents that are preferably used in several injections, for example, divided into three times, morning, noon, and evening, are not necessarily preferable. Absent.

That is, in the conventional quantitative injection, the entire amount of the aerosol content measured quantitatively is injected once. However, if a certain amount of aerosol contents must be used in multiple times during a certain period such as one day, one week, etc., the user may forget the number of times of use, May not be consumed or may exceed the amount used, resulting in pharmaceutically undesirable results.

[0005] The present invention is intended to solve the above-mentioned problems, and is intended for use in medicines, hair products, cosmetics, and the like in which the amount of use within a prescribed period such as one day or one week is limited. In this way, it is possible to reliably protect the usage. Furthermore, within the specified period, multiple injections are possible,
The injection amount for each injection is also constant. Then, the injection of the aerosol contents is performed quantitatively by integrating the plural times of injections with the fixed amount, thereby enabling the efficient use of the aerosol contents.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a metering chamber communicating with a stem is provided in a body in which a stem of an aerosol container is arranged so as to be able to be pressed.
A piston capable of pressurizing the contents of the aerosol introduced into the fixed volume chamber is slidably mounted in the main body, and a distributing nozzle which can communicate with the fixed volume chamber and inject the aerosol content in the fixed volume chamber, and a distribution valve. The dispensing valve is connected to the main body via a nozzle, and this dispensing valve is used as a dispensing valve for dispensing a fixed amount of the aerosol contents. The connection is made.

The erroneous injection preventing mechanism of the distributing nozzle comprises a preventing projection provided at the lower end of the distributing nozzle and a release hole of the substrate facing the lower end of the preventing projection. Dispenses the dispensing nozzle by pushing down the dispensing nozzle to enable the ejection of the aerosol contents.When the stem is pressed by the main body, the dispensing nozzle disengages the disengagement protrusion from the disengagement hole. May be disabled.

The dispensing nozzle may open the dispensing valve by pressing the dispensing nozzle against the target for jetting the aerosol contents, so that the aerosol contents can be jetted.

Further, the distribution nozzle may be connected to a push button which is manually pressed.

[0010]

Since the present invention is constructed as described above, the control valve of the aerosol container is opened by first pressing the main body and pushing down the stem of the aerosol container.
By opening the control valve of the aerosol container, the contents of the aerosol are introduced into the metering chamber communicating with the stem.

Along with the introduction of the aerosol contents, the piston is pushed by the injection pressure of the aerosol contents and rises in the main body, and introduces the aerosol contents into the fixed amount chamber up to the rising limit. At the upper limit of the piston, the introduction of the aerosol contents is stopped, so that a fixed amount of the aerosol contents is always introduced into the metering chamber by one pressing of the main body.

In this introduction process, unless a distribution valve interposed between the metering chamber and the distribution nozzle is opened,
The aerosol contents of the metering chamber are not sprayed from the dispensing nozzle. However, if the distribution valve is opened with the stem pressed down, the aerosol content can be continuously ejected from the distribution nozzle from the aerosol container through the metering chamber in a quantity exceeding a certain amount. But,
Since the erroneous injection prevention mechanism is connected to the dispensing nozzle of the present invention, the distributing valve does not accidentally open when the stem of the aerosol container is pushed down. Therefore, the erroneous injection of the aerosol content can be reliably prevented, and the aerosol content will not be erroneously injected beyond the specified amount.

After the introduction of the contents of the aerosol into the fixed quantity chamber is completed, the pressing of the main body against the stem of the aerosol container is released. In this release state, the communication between the fixed amount chamber and the inside of the aerosol container is cut off by the control valve on the aerosol container side, and the communication between the fixed amount chamber and the outside is cut off by the distribution valve arranged in the main body.

Next, when the stem of the distribution valve communicating with the fixed amount chamber is pressed via a push button, an actuator or the like, the distribution valve is opened, and the aerosol content is ejected from the distribution nozzle to the outside. When the aerosol contents are sprayed by the distribution nozzle through the distribution valve, since the inside of the aerosol container is closed by the control valve on the aerosol container side, the aerosol contents are injected into the fixed amount chamber. Is limited to

Therefore, even when the aerosol contents are injected a plurality of times, the injection of a predetermined amount or more in the fixed amount chamber is not performed. In addition, since the dispensing valve is a constant-volume valve that injects a fixed amount of the aerosol content in the constant-quantity chamber, it is possible to quantitatively perform multiple injections by the dispensing nozzle from the constant-quantity chamber. Problems such as non-uniformity in the amount of use for each injection can be prevented, and a preferable injection state can be obtained. And the effect of the aerosol content can be exhibited effectively, and efficient use becomes possible.

In addition, the aerosol content in the metering chamber decreases as the aerosol content decreases due to the continuous injection from the dispensing nozzle to the outside, thereby lowering the injection pressure. However, since the piston constantly presses the contents of the aerosol in the metering chamber, the pressure drop of the contents of the aerosol is minimized, and the injection of the contents of the aerosol from the distribution nozzle is not hindered.

Therefore, if the amount of the aerosol contents in the metering chamber is limited to the amount used during a specified period such as one day or one week, the dispensing nozzle is set at a specified number of times within the specified period. By injecting a predetermined amount from each, the entire amount can be used so as to be used up within a specified period, and the aerosol content is not excessively used.

Even if the distribution nozzle is operated with the stem of the aerosol container opened, the distribution valve cannot be opened and the aerosol contents cannot be injected by the erroneous injection prevention mechanism. Will not use the aerosol contents beyond the licensed amount of the aerosol.

For this reason, it is advantageous when used in medicines, hair supplies, cosmetics, etc., in which the amount used during a prescribed period and the amount used at one time are limited. Then, when the use of the amount specified in the specified period is completed and the injection of the aerosol content in the fixed amount chamber is completed, when the next specified period starts, the main body is pressed again to control the aerosol container. And introduce the aerosol contents into the metering chamber. Then, by using the dispensing nozzle to perform a plurality of injections in a fixed amount, a quantitative use of the aerosol content in a specified period becomes possible.

The erroneous injection preventing mechanism of the distribution nozzle may be formed by any mechanism as long as the opening of the distribution valve can be prevented when the stem of the aerosol container is pushed down. It may be constituted by a prevention projection provided at the lower end and a release hole of the substrate facing the lower end of the prevention projection.

When the stem is not pressed by the main body,
The prevention protrusion and the release hole are positioned so as to be engageable by, for example, rotating a push button or an actuator provided with a distribution nozzle or releasing a lock. By the engagement between the prevention protrusion and the release hole, the distribution nozzle is pushed down to open the distribution valve, and the aerosol contents can be ejected. Also, when the stem is pressed by the main body, the position of the prevention protrusion and the release hole is shifted or locked, so that the disengagement nozzle cannot be pushed down by disabling engagement. Then, the distributing valve cannot be opened and the erroneous injection of the aerosol contents is reliably prevented.

As the distribution nozzle, a conventionally known appropriate nozzle can be used according to the purpose of use.
The distribution valve is opened by pressing the distribution nozzle against the jetting target of the aerosol contents such as the head, skin, etc., and if the aerosol contents can be jetted, the distribution valve can be easily opened. In addition, it is possible to reliably apply the liquid to the injection target portion, and it is possible to prevent scattering and use the aerosol content without waste. Further, the distribution nozzle may be connected to a push button that is manually pressed.

The aerosol dispensing device for aerosol containers is used for aerosol contents such as hair products, cosmetics, deodorant / antiperspirants, other human body products, insecticides, industrial products, automobile products, foods and the like. Can do things. And as a hair product, it can be used as a hair restorer, a hair growth agent and the like. Further, it can be used as a cosmetic, such as a lotion. In addition, as other human body products, it can be used as a muscle anti-inflammatory agent, a skin disease agent, an athlete's foot medicine, a pest repellent, a wiping agent, an oral preparation, a wound medicine, a burn treatment, and the like.

The board (22) is fixed to the upper end by fitting the fixing projection (21) of the board (22) into the fixing hole (29). This board
By interposing a pressing ridge (23) between (22) and the piston (20), the pressing ridge (23) is moved in the direction of narrowing the fixed amount chamber (18) in the inner cylinder (15). , The piston (20) is pressed and urged. The pressing line (23) has a pressing force slightly smaller than the injection pressure of the propellant filled in the aerosol container (1). The outer cylinder (11), the inner cylinder (15), and the substrate (22) form a main body (19).

The piston (20) has an aerosol outlet path (24) formed in the center in the vertical direction. And the piston (20) which formed this outlet path (24)
(25) protrudes toward the substrate (22). Further, the piston (20) is connected to the lower end opening edge (39) of the substrate (22).
And the sliding can be stopped.

As shown in FIG. 7, a distribution valve (27) is housed on the inner surface of the upper end of the substrate (22), and a distribution nozzle (28) is arranged via the distribution valve (27). This distribution valve
(27) connects the lower end of the distribution housing (26) to the piston (2).
The distribution housing (26) is inserted into the discharge pipe (25) of the first embodiment (0), and a distribution quantitative chamber (30) is formed in the distribution housing (26). And the piston (2
When (0) moves up and down, the outlet pipe (25) can freely move up and down while keeping its inner periphery in close contact with the outer periphery of the distribution housing (26). Further, a distribution stem (32), which is constantly pressed and urged outward by a distribution ridge (31), is arranged in the distribution fixed amount chamber (30).

This distribution stem (32) has a distribution orifice.
(33) is normally closed by the distribution gasket (34), and the communication between the inside of the metering chamber (18) and the distribution nozzle (28) is performed.
It is closed by the distribution gasket (34). Also, the dispensing stem (32) projects a stopper (37) at the lower end,
A communication port (38) for communicating the lead-out path (24) of the metering chamber (18) with the distribution metering chamber (30) is formed so as to be able to be closed.

Then, at the upper end of the distribution stem (32),
An actuator (40) provided with a distribution nozzle (28) is connected. As shown in FIGS. 1 and 2, this actuator (40) forms distribution nozzles (28) communicating with the fixed quantity chamber (18) via distribution valves (27) at the center and at four places in the circumferential direction. ing. The actuator (40) has an engaging portion (36) connected to the distribution stem (32) at the center, and an annular cylinder (35) provided on the outer periphery of the engaging portion (36).
Is housed in the outer cylinder (11).

The annular cylinder (35) has a pair of fitting ribs (42) protruding in the vertical direction on the outer circumference, and is engaged with the fitting groove (43) provided in the vertical direction on the inner circumference of the outer cylinder (11). By combining, it is formed to be vertically movable and non-rotatable.

The actuator (40) presses the distribution stem (32) by pressing against the scalp, which is the injection target of the aerosol contents, to open the distribution valve (27), and the distribution nozzle (28). ) Without dispersing around
The aerosol contents can be sprayed directly on the scalp.

Further, the distribution nozzle (28) is connected to an erroneous injection prevention mechanism, and the structure thereof is the same as that of the actuator (4).
A pair of prevention protrusions (4) provided at the lower end of the annular cylinder (35) of (0).
4) and the inner cylinder (1) facing the lower end of the prevention protrusion (44).
A release hole (45), which is disposed on the upper surface of the substrate (5) of (5) and can be engaged with the prevention projection (44). In addition, this release hole (4
5), two pairs are arranged at an angle of 120 degrees.

In this erroneous injection prevention mechanism, the outer projection (16) of the inner cylinder (15) is located at one of the non-injection portions (14) provided at both ends of the groove cam (12) of the outer cylinder (11). When the stem (4) is not pressed by the body (19), the prevention protrusion (44) and the release hole (4) are not pressed.
5) is arranged so as to be engageable. In this engaged position, the actuator (40) can be depressed and the distribution valve (27) is opened, allowing the aerosol contents to be ejected from the distribution nozzle (28).

Further, the outer peripheral projection (16) is rotated to rotate the groove cam.
By sliding inside the injection operation part (13) of (12), the main body
When the stem (4) is pressed by (19), the release hole
Since the substrate (22) provided with (45) also rotates, the prevention protrusion
By displacing the position of (44) and the release hole (45) and disabling the engagement, disabling the pressing of the actuator (40) makes it possible to prevent the spray of the aerosol content from the distribution nozzle (28). .

In the above-mentioned construction, at the time of shipment, as shown in FIG. 4, the outer peripheral projection (16) of the inner cylinder (15) is
It is located at the non-injection portion (14) of the groove cam (12) of the outer cylinder (11),
The stem (4) of the aerosol container (1) is in a non-pressed state, and the piston (20) in the main body (19) is urged in the direction of the aerosol container (1) by the restoring force of the pressing ridge. . In addition, the prevention protrusion (4) of the actuator (40)
4) and the release hole (45) of the substrate (22) are arranged at positions where they can be engaged with each other.

Then, in order to perform the divided distribution injection of the aerosol contents, first, the outer cylinder (11) and the aerosol container (1)
While holding the inner cylinder, the inner cylinder protruding from the outer cylinder (11).
(15) is pressed in the circumferential direction on the outer projection (16), and the inner cylinder (1) is pressed.
5) is rotated. Then, the outer peripheral projection (16) is
As shown in (1), the groove cam (12) is slid from one non-injection portion (14) to the injection operation portion (13). This injection operation part (1
As the inner cylinder (15) descends with the sliding to (3) and the stem (4) of the aerosol container (1) is pressed, the control valve (3) of the aerosol container (1) is opened, As shown in FIG. 5, the contents of the aerosol in the aerosol container (1) are communicated with the communication passage (17).
Flows into the fixed amount chamber (18) of the inner cylinder (15) through the internal combustion engine.

The contents of the aerosol are supplied to a piston (20).
Since the piston (20) is pressed with a pressure slightly stronger than the restoring force of the pressing struts (23), the piston (20) rises against the restoring force of the pushing struts (23), and is moved into the fixed amount chamber (18). The aerosol contents are introduced into Further, the upper end of the piston (20) abuts on the lower end opening edge (39) of the substrate (22), and the ascent of the piston (20) stops. As the piston (20) stops rising, the fixed amount chamber (18) is filled with a predetermined amount of aerosol contents.

The contents of the aerosol are introduced not only into the metering chamber (18) but also into the distribution metering chamber (30) of the distribution valve (27) via the outlet path (24). This distribution metering room (30)
Since the distribution orifice (33) of the distribution stem (32) is closed by the distribution gasket (34), the aerosol contents are not jetted to the outside in this state.

In the process of introducing the aerosol contents, the erroneous injection preventing mechanism connected to the distributing nozzle (28) operates, so that the user may erroneously operate the actuator.
Even if (40) is pressed, the distribution valve (27) cannot be opened, and the effect of preventing erroneous injection of aerosol contents is enhanced.

That is, even if the inner cylinder (15) rotates in the opening direction of the control valve (3), the actuator (40) is rotated by the engagement between the fitting groove (43) and the fitting rib (42). Without, prevent protrusion
(44) relatively moves on the substrate (22) within a range not in contact with the release hole (45), and as shown in FIG. 5, the prevention projection (44) and the release hole (45) cannot be engaged. ing. Therefore, the actuator (40) cannot be pressed, and the distribution valve
The valve opening of (27) is surely prevented.

In the process in which the outer peripheral projection (16) of the inner cylinder (15) passes through the injection actuating section (13), the fixed amount chamber (18) is filled with the aerosol content in a predetermined amount for one day. The outer projection 16 is moved to the other non-ejecting portion 14 by holding the outer projection 16 with a hand, a finger, or the like and further rotating the outer projection 16. By this movement, as shown in FIG. 6, the aerosol container
The pressing of the stem (4) provided on the control valve (3) of (1) is released.

When the pressure on the stem (4) is released, the control valve (3) of the aerosol container (1) is closed, and the communication between the inside of the aerosol container (1) and the metering chamber (18) is cut off. Also,
By the movement of the outer peripheral projection (16) to the non-injection part (14),
As shown in FIG. 6, the prevention protrusion of the actuator (40)
Since the release hole (45) of the substrate (22) is arranged facing (44), the actuator (40) can be pressed.

Then, in order to use the aerosol contents of the metering chamber (18) in several times by injecting the metered amount at a time, the distribution nozzle (28) of the distribution valve (27) is used. The distribution nozzle (28) is, in this embodiment, a distribution stem of the distribution valve (27).
It is provided on an actuator (40) connected to (32). By pressing this actuator (40) against the scalp of the user, as shown in FIGS.
(32) is pressed and the distribution orifice (33) is released from the sealing of the distribution gasket (34). This distribution orifice
By opening (33), the contents of the aerosol in the dispensing / quantifying chamber (30) are ejected from the dispensing nozzle (28) to the outside.

When the dispensing stem (32) is pressed, as shown in FIGS. 1 and 7, a stopper (37) protruding from the lower end of the distributing stem (32) is connected to a communication port for communicating with the fixed amount chamber (18). (3
8) to close the communication port (38). For this reason, the aerosol contents ejected from the dispensing nozzle (28) are limited to the aerosol contents in the dispensing / quantifying chamber (30), so that a fixed amount of the aerosol contents can be ejected. Therefore, not only the daily usage amount but also the single usage amount is defined, and when it is desired to perform multiple injections evenly, the user does not need to measure the specified amount with a scale or a can. In addition, it is possible to easily perform the fixed amount injection. Furthermore, it is possible to prevent excessive or insufficient use or uneven injection of the amount of use, and to use the hair restorer efficiently and safely so that the effect of the hair restorer can be exhibited effectively and safely.

Then, after the injection of a fixed amount of the aerosol content in the dispensing and measuring chamber (30) is completed, the actuator
When release of the distribution stem (32) through (40) is released,
The distributing stem (32) is restored to its original position by the restoring force of the distributing beam (31), and the distributing orifice (33) is moved to the distributing gasket (3).
Closed by 4). Further, the communication port (38) closed by the stopper (37) is opened, and the dispensing and quantifying chamber (30) communicates with the quantifying chamber (18).
Due to the pressing force of the piston (20), a certain amount of aerosol content for the next use is introduced from the metering chamber (18).

As described above, by introducing a fixed amount of aerosol contents each time the fuel is injected from the distribution nozzle (28),
The user can inject a certain amount of aerosol contents at the time of next and subsequent use. Further, even when the aerosol contents are injected a plurality of times, the piston (20) is kept in the fixed amount chamber (1).
8) Since the aerosol content inside is constantly pressed, the pressure drop of the aerosol content is minimized, and the distribution nozzle
The injection of the aerosol contents from (28) does not hinder. Furthermore, since the amount of the aerosol content in the metering chamber (18) is constant, the total injection amount of the aerosol content is constant regardless of how many times the aerosol content is injected by the dispensing nozzle (28). Amount.

Therefore, if the total injection amount of the aerosol contents is made to correspond to the injection amount for one day or the injection amount for several days or one week, the specified period for one day or the like is obtained. Injection in this process is always performed in a fixed amount, and a plurality of injections in this specified period are also performed in a fixed amount. Therefore, it is advantageous when it is used in pharmaceuticals and cosmetics, for example, pharmaceuticals and hair tonics whose excessive use is to be suppressed.

In the above embodiment, the distribution nozzle (28)
The actuator (4) presses the distribution stem (32) to open the distribution valve (27) by pressing against the scalp.
0), but in another alternative embodiment, the dispensing nozzle (28) may be connected to a suitable push button that is manually pressed. By forming in this manner, the aerosol device can be formed simply and inexpensively, and it can be used for application to a portion such as a wound where the actuator (40) cannot be pressed.

[0052]

As described above, the present invention is constructed as described above, so that a fixed amount of injection within a specified period can be performed by a plurality of fixed amount injections from the distribution nozzle. It is possible to distribute the aerosol contents conveniently in pharmaceuticals, hair products, cosmetics, etc., in which use of more than the desired amount is not preferred. In addition, since a fixed amount of aerosol contents can be injected by the fixed amount valve in this way, the user can always keep the specified amount of use within a specified period without relying on the scale or the can. The aerosol contents can be sprayed in an amount, and the aerosol contents can be used efficiently, and the effect of the aerosol contents can be effectively exhibited.

Since the erroneous injection prevention mechanism is connected to the distribution nozzle, the distribution valve cannot be opened by mistake when the stem of the aerosol container is pushed down. Therefore, while the specified amount of the aerosol content is being measured, it is possible to reliably prevent erroneous injection of the aerosol content from the dispensing nozzle, and also to prevent the use of the aerosol content exceeding the specified amount by mistake. Become.
