Description

[0001]
[Industrial application fields]
The present invention relates to a continuous injection device for continuously injecting aerosol contents such as fragrances, deodorants and insecticides in a constant amount.
[0002]
[Prior art]
Conventionally, when injecting aerosol contents, there is a method of injecting by pressing the stem of an aerosol container via a push button or the like. In this case, a push button or the like connected to the aerosol container stem is pressed with a human finger or the like, and the aerosol contents are ejected only during the pressing time. As another conventional method, once the pressing operation is performed through a mechanism that continuously presses the stem of the aerosol container, the aerosol contents are continuously released to the outside without continuing the pressing operation with a finger or the like. There is a structure that can be sprayed.
[0003]
And what allows the aerosol contents to be ejected only for the time of pressing with the finger or the like is performed by the operator while confirming the ejection state, so the control of the ejection amount is complete and the mechanism is simple. It has certain advantages.
[0004]
[Problems to be solved by the invention]
However, since the stem of the aerosol container is pressed with fingers or the like while the aerosol contents are being ejected, there is a drawback that the ejected aerosol contents come into contact with the operator. For this reason, fragrances, deodorants, insecticides, and the like may cause drug poisoning such as irritating odors attached to clothes or feeling bad, and may adversely affect the operator.
[0005]
Further, once the pressing operation is performed, another different conventional method of continuing to inject the aerosol contents is to exhaust all the aerosol contents in the aerosol container to the outside by one pressing operation. . For this reason, there is an apparatus in which the aerosol contents in the aerosol container can be injected in a plurality of times, and a certain amount of aerosol contents are continuously injected for a fixed time by one pressing operation.
[0006]
As a conventional technique for injecting a certain amount of aerosol contents for a certain period of time by this single pressing operation, there is a device as described in Japanese Utility Model Laid-Open No. 61-87556. In this device, the stem of the chilled valve is pressed with a pressing body having a rubber sucker, thereby opening the valve mechanism for a certain period of time and continuously injecting aerosol contents. When a certain time has elapsed, the suction force of the suction cup is released by the restoring force of the chilled valve stem, and the injection of the aerosol contents is stopped.
[0007]
However, the rubber suction cups are prone to rubber deterioration, breakage and wear due to repeated use, and the chilled valve stem cannot be satisfactorily fixed by suction, and the structure of the ejection nozzle is complicated. .
[0008]
In order to solve the above-described problems, the present invention does not inject the entire aerosol content of the aerosol container with a single pressing operation, but continuously only a certain amount of the aerosol content by a single operation. It is an object of the present invention to provide a continuous injection device for aerosol contents that can be injected. By setting it as such a structure, only a fixed quantity of the aerosol content accommodated in the aerosol container can be continuously injected by one press operation.
[0009]
Therefore, the operator has the advantage of being hardly affected by the aerosol contents by immediately leaving the injection site after performing this pressing operation. Further, since the entire amount is not ejected by a single operation, the operator can repeatedly inject the aerosol contents continuously. Due to such advantages, an advantageous product can be obtained when spraying aerosol contents such as fragrances, deodorants, and insecticides.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention connects a pressing body provided with a storage chamber for the aerosol contents ejected from the stem to the stem of the aerosol container, and the pressing of the stem by the pressing body causes the aerosol container to An ejection nozzle having an ejection amount smaller than the inflow amount per unit time flowing into the storage chamber from the stem is formed in the communication portion between the storage chamber and the outside so that the valve mechanism can be opened , and the stem and the storage chamber The introduction nozzle that communicates with the storage chamber and the ejection nozzle opens radially to the axial direction of the ejection pipe that prevents the aerosol contents ejected from the stem from flowing directly into the ejection pipe. after flowing into the storage chamber, it is to be calculated and assumed to flow into the ejection tube from the housing chamber.
[0011]
In addition, the aerosol container has a dip tube connected to the lower end of the housing of the valve mechanism, and a check valve is arranged at the lower end of the dip tube to allow the aerosol contents to flow into the dip tube, but the contents of the aerosol that flowed in The object may not be restored in the aerosol container.
[0012]
[Action]
Since the present invention is configured as described above, when the aerosol contents are to be continuously jetted, the pressing body is pressed with fingers or the like, and the valve mechanism of the aerosol container is opened through the stem. By this opening, the aerosol contents in the aerosol container flow into the storage chamber of the pressing body. The aerosol contents in the storage chamber are ejected to the outside through a spray nozzle formed in a communication portion between the storage chamber and the outside.
[0013]
However, since this ejection nozzle has a smaller amount of ejection to the outside per unit time than the amount of aerosol content flowing into the storage chamber, the aerosol content flowing from the inside of the aerosol container into the storage chamber. Most of them are stored in the storage chamber. And if the press to a press body is cancelled | released, since the valve mechanism will be closed, the inflow to the storage chamber of the aerosol contents will stop.
[0014]
However, as described above, since the aerosol content remains in the storage chamber, the residual aerosol content is continuously ejected to the outside from the ejection nozzle. The ejection of the aerosol contents from the ejection nozzle continues until all the aerosol contents in the storage chamber are ejected to the outside.
[0015]
Thus, since the aerosol content larger than the amount of ejection per unit time from the ejection nozzle is stored in the storage chamber by a single pressing operation on the pressing body, the operator holds the pressing body only once for a short time, You can move out of the room, etc. just by pressing. Therefore, the operator is hardly affected by the aerosol contents, and a sufficient amount of the aerosol contents can be injected into the room.
[0016]
Further, as in the prior art, not all the aerosol contents in the aerosol container are used up by a single pressing operation, but only a certain amount of the aerosol contents in the aerosol container are continuously ejected. Therefore, the operator can repeatedly perform the continuous injection of the aerosol contents as required.
[0017]
Therefore, the present invention quantitatively applies only a part of the aerosol contents, not the total amount in the aerosol container, such as the injection of the fragrance into the room such as the toilet, the injection of the deodorant or insecticide into the room. Moreover, it is convenient when trying to inject continuously.
[0018]
And as a fragrance | flavor, it is suitable for injection of the fragrance for toilets, the fragrance for indoors, the fragrance for motor vehicles, etc. Moreover, as a deodorant, it is suitable for injection, such as a room deodorant and a car deodorant. Moreover, as an insecticide, it is suitable for injection of a space insecticide, a cockroach insecticide, a gardening insecticide, an acaricide, an unpleasant insecticide, etc.
[0019]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (1) is an aerosol container, and a metal cap (2) is fastened and fixed to the upper end, and the upper end of the metal cap (2) is attached to a mountain cup. Covered by (3). The housing (5) of the valve mechanism (18) is fixed to the central part of the mountain cup (3) via a stem gasket (4). A stem (6) is inserted into the housing (5), and the stem (6) protrudes upward from the mountain cup (3) by the pressing force of the stem ridge (7). Furthermore, when the stem (6) is pressed by the stem ridge (7), the inside and outside of the aerosol container (1) are not always communicated by the stem gasket (4).
[0020]
A dip tube (8) is connected to the lower end of the housing (5), and the dip tube (8) is disposed up to the lower end of the aerosol container (1). Further, the dip tube (8) is curved so that the aerosol contents (11) can be used up without waste, and the lower end faces the lower bottom corner of the aerosol container (1). A check valve (10) formed of a ball or the like is disposed at the lower end of the dip tube (8). When the aerosol content (11) is ejected, as shown in FIG. 2, the check valve (10 ) And the aerosol contents (11) can be introduced into the dip tube (8). However, after the ejection is completed, the check valve (10) seals the lower end of the dip tube (8), and the aerosol content (11) contained in the dip tube (8) enters the aerosol container (1). Prevents outflow.
[0021]
The stem (6) is connected to a pressing body (12) provided therein with a storage chamber (14) for the aerosol contents (11). The pressing body (12) is inserted into a fixing member (13) fixed to the outer periphery of the mountain cup (3) of the aerosol container (1) so as to be movable up and down, and has a lower end fixed to the aerosol container (1). It is connected to the stem (6) of (18). The pressing body (12) has an introduction nozzle (15) that communicates the stem (6) and the storage chamber (14) on the lower end side connected to the stem (6).
[0022]
Further, a jet pipe (16) is arranged in the upper direction facing the introduction nozzle (15), and by this jet pipe (16), the space in the lower bottom direction of the storage chamber (14) and the pressing body (12 The aerosol contents (11) in the storage chamber (14) can be ejected to the outside by communicating with the ejection nozzle (17) provided at the upper end of the nozzle. The introduction nozzle (15) opens radially from the stem (6) in the direction of the storage chamber (14), so that the aerosol content (11) ejected from the stem (6) directly enters the ejection pipe (16). It is assumed that after flowing into the storage chamber (14), it flows into the ejection pipe (16) from the storage chamber (14).
[0023]
Further, the ejection nozzle (17) provided at the upper end of the pressing body (12) and the introduction nozzle (15) communicating with the stem (6) include the aerosol content (11) from the introduction nozzle (15) per unit time. ), The amount of ejection from the ejection nozzle (17) is smaller than the amount of outflow. The difference in the ejection amount can be set arbitrarily, but the ejection nozzle is smaller than the amount of the aerosol content (11) ejected from the introduction nozzle (15) when the pressing body (12) is pressed for 1 second. In one embodiment, the quantity ratio is such that the ejection from 17 to 18 seconds continues from (17) . To main, inflow housing chamber (14) of the aerosol content (11), in which may be made of such larger than the ejection amount from the ejection nozzle (17) to the outside.
[0024]
When the aerosol contents (11) are not ejected in the configuration as described above, the valve mechanism (18) and the check valve (10) of the dip tube (8) are closed as shown in FIG. is doing. When the aerosol contents (11) are ejected, the valve mechanism (18) can be obtained by pressing the pressing body (12) with a finger or the like for a short time to press the stem (6) as shown in FIG. ) Is open. Since the check valve (10) is opened together with the opening of the valve mechanism (18), the aerosol content (11) in the aerosol container (1) flows into the housing (5) through the dip tube (8). .
[0025]
The aerosol content (11) in the housing (5) flows into the storage chamber (14) via the stem (6) and the introduction nozzle (15), and is ejected at the upper end of the pressing body (12). It ejects to the outside from the nozzle (17). However, since the amount of ejection from the ejection nozzle (17) provided at the upper end of the pressing body (12) to the outside is smaller than the amount of inflow per unit time into the storage chamber (14), the aerosol contents (11) is stored in a certain amount in the storage chamber (14).
[0026]
Therefore, even if the valve mechanism (18) of the aerosol container (1) is closed after a short time pressing against the pressing body (12), the aerosol contents (11 remaining in the storage chamber (14) are retained as shown in FIG. ) Are continuously ejected in small amounts from the ejection nozzle (17). Therefore, after a short time pressing operation on the pressing body (12), the operator can leave the jetting site to the outside, and is less likely to be adversely affected by the aerosol contents (11).
[0027]
Moreover, even if it is a pressing operation for a short time, it becomes possible to inject a sufficient amount of aerosol contents (11) into the room. In addition, since the entire aerosol content (11) in the aerosol container (1) is not used up by a single press, the next time the pressing body (12) is pressed for a short time, an aerosol of approximately the same amount as the previous time. It becomes possible to continuously inject the contents (11).
[0028]
Moreover, the check valve (10) provided at the lower end of the dip tube (8) is also closed by releasing the pressing of the pressing body (12) and closing the valve mechanism (18). If this check valve (10) is not provided, the aerosol content (11) in the dip tube (8) flows out into the aerosol container (1) by its own weight, and in the dip tube (8) at the next injection. The vaporized gas flows into the storage chamber (14). Therefore, the amount of the aerosol content (11) introduced into the storage chamber (14) is reduced, and even when the pressing time to the pressing body (12) is the same, the aerosol content (11) is stored in the storage chamber (14). Variation in introduction.
[0029]
However, in this embodiment, since the check valve (10) is provided in the dip tube (8), the check valve (10) is also closed together with the closing of the valve mechanism (18), and the aerosol in the dip tube (8) is closed. The contents (11) are not restored in the aerosol container (1). In the next injection, since the aerosol content (11) in the dip tube (8) is also introduced into the storage chamber (14), the quantitative injection of the aerosol content (11) can be performed reliably. .
[0030]
【The invention's effect】
Since the present invention is configured as described above, it is possible to continuously inject a certain amount of aerosol contents for a certain period of time by pressing the pressing body for a short time. Therefore, when spraying fragrances, deodorants, insecticides, etc., it is possible to sufficiently achieve the work purpose of the aerosol contents while minimizing the influence of the aerosol contents on the operator It is.
