Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aerosol apparatus and an injection method. More specifically, the present invention relates to an aerosol apparatus and a spraying method that are used by being placed on a floor or a table, and are used to diffuse and uniformly disperse a drug in a room or the like at a low position over a wide range.
[0002]
[Prior art]
In order to disperse medicines such as insecticide, deodorant, disinfectant or disinfectant in the space, a so-called aerosol device of a spray type is used.
[0003]
In the aerosol device, a medicine is sealed in a bottomed cylindrical container together with a high-pressure propellant, and the medicine is ejected in a mist form from an injection nozzle by operating an injection button.
[0004]
These aerosol devices can be broadly classified into the types of aerosol devices that users hold and use, and the types of aerosol devices that are used on the floor, etc. When trying to do so, it is convenient to use the latter floor-standing type aerosol apparatus.
[0005]
In some floor-standing type aerosol apparatuses, the injection nozzle or the entire aerosol apparatus rotates in order to uniformly inject a medicine over a wider range.
[0006]
An aerosol device in which an injection nozzle rotates is disclosed in, for example, Japanese Utility Model Publication No. 62-187663, and an injection nozzle located at the top of an aerosol container placed on a floor surface or the like has a reaction force of injection. It will rotate.
[0007]
An aerosol device of the type in which the entire device rotates is disclosed in, for example, Japanese Utility Model Laid-Open No. 63-181467. The bottom surface of the aerosol container is curved so that the entire aerosol device is floored by the reaction force of injection. It slides and rotates on the surface.
[0008]
These rotary aerosol devices spray medicines upward while the spray nozzle or the entire device rotates, so a wider range of space compared to hand-held aerosol devices and floor-mounted aerosol devices that do not rotate. Can diffuse the drug.
[0009]
In addition, even when the drug is spread on the floor, such as when a tick is removed, the drug spread widely in the air can be dropped to spread the drug over a wide range of floors.
[0010]
However, on the other hand, these conventional rotary aerosol devices push the injection button, and at the same time, the drug is sprayed upward and rotating, so the drug is also sprayed on the user side and the drug is applied to the user. There has been a problem of sucking or inhaling drugs.
[0011]
In order to solve this problem, it is possible to apply a so-called delay-type injection button in which injection is started after a certain time has passed after the injection button is pushed, but the structure is complicated and reliability is reduced. Have disadvantages such as difficulty and cost.
[0012]
In addition, some drugs are not preferable if they adhere to other than the target. However, in the conventional rotary aerosol device, for example, it is not possible to meet the demand of spraying the medicine only on the floor surface while avoiding the upper surface of the table.
[0013]
[Problems to be solved by the invention]
The present invention solves the above-described problems, and provides an aerosol device and an injection method capable of uniformly injecting a medicine over a wide range at a low position and preventing adhesion to other than the object. provide.
[0014]
[Means for Solving the Problems]
The aerosol device and the medicine injection method of the present invention vary the injection direction of the medicine by the reaction of the injection of the medicine, and the diffusion range of the medicine is based on the aerosol device as the origin, and a plane whose elevation angle from the horizontal plane and the horizontal plane is 70 ° or less. It is characterized by being in the space between.
[0015]
Furthermore, the height from the horizontal surface of the diffusion range of the drug is 1.5 m or less.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
The aerosol device and the drug injection method of the present invention change the injection direction of the drug by the reaction of the injection of the drug, and the diffusion range of the drug is a plane whose origin is the aerosol apparatus and the elevation angle from the horizontal plane and the horizontal plane is 70 ° or less. It was made to be in the space between. Furthermore, the height from the horizontal plane of the diffusion range of the drug was set to 1.5 m or less.
[0017]
By changing the injection direction, the medicine can be diffused over a wide range at a low position and the medicine can be dispersed uniformly. Furthermore, since the diffusion range of the drug is set in a space whose elevation angle from the horizontal plane is 70 ° or less, it is possible to prevent the spread drug from adhering to an unfavorable surface such as the upper surface of a table. it can. In addition, by setting the height of the diffusion range of the drug from the horizontal plane to 1.5 m or less, an accident such as suction to the human body can be prevented.
[0018]
The aerosol device and injection method of the present invention will be described in more detail with reference to the accompanying drawings.
[0019]
Embodiment 1
1 and 2 are views showing an example of an embodiment of an aerosol device and an injection method according to the present invention.
[0020]
In the present embodiment, the aerosol device includes a container 1 enclosing a medicine, an injection member 2 having an injection button 2a and an injection nozzle 2b, a shoulder cover 3, and a stand 4.
[0021]
As shown by an arrow A in FIG. 1A, the injection member 2 and the shoulder cover 3 are attached to the container 1. The shoulder cover 3 is engaged with and attached to the bead portion 1a of the container 1 as shown in cross section in FIG. The injection member 2 is attached by inserting a stem 19 into the stem insertion hole 2c, and includes an injection button 2a for operating the stem 19 and an injection nozzle 2b for ejecting a medicine.
[0022]
When the injection member 2 is rotated so that the flange 2d of the injection button 2a and the engaging portion 3a of the shoulder cover 3 are engaged with each other by pushing down the injection member 2, the injection button 2a keeps the stem 19 pushed in. Injection starts. One or a plurality of flanges 2d and engaging portions 3a may be provided.
[0023]
When the container 1 that has started injection is placed on the stand 4, the container 1 rotates on the stand 4 as indicated by an arrow R by the reaction force of the injection. A roller 5 may be provided on the stand 4 in order to make the rotation reliable and smooth.
[0024]
The stand 4 is provided with an inclination, and the elevation angle formed between the injection direction and the floor surface changes continuously and periodically as the container 1 rotates. Accordingly, the medicine is jetted in the vicinity of the aerosol device when the elevation angle of ejection is small, and far away when the elevation angle becomes large, and uniformly distributed over a wide range as a whole.
[0025]
Needless to say, since the container 1 rotates by the injection, the injection direction of the injection nozzle 2 b does not intersect the central axis of the container 1.
[0026]
Furthermore, in order to achieve the object of the present application, in which the medicine is uniformly sprayed over a wide range and is prevented from adhering to other than the target object, the diffusion range of the medicine sprayed by the spray nozzle 2b is the floor surface and the elevation angle from the floor surface. Is within the range between 70 ° or less, preferably 60 ° or less. When the diffusion range is 70 ° or more, the chemical solution reaches a high position, and the chemical solution adheres to an object that the chemical solution is not desired to adhere to.
[0027]
In order to make the drug diffusion range within the above range, in this embodiment, the spray range of the drug when placed on the stand 4 is 60 ° or less, preferably 50 ° or less from the floor surface. The angles of the stand 4 and the injection nozzle 2b may be selected. In addition, although the pattern at the time of the injection has the shape of a cone when it injects, the centerline of a pattern is shown here. When the injection range is 60 ° or more, the chemical solution easily reaches a high position. In consideration of suction to the human body and adhesion to a high position, the chemical solution is preferably diffused at a position lower than the chest or lower back of the human body, specifically 1.5 m or less, and further 1.0 m or less. In particular, 0.8 m or less is preferable.
[0028]
According to the present embodiment, since the injection direction can be predicted and the medicine is not injected to the user side, it is possible to prevent an accident such as being applied to the user or being aspirated.
[0029]
In addition, unlike conventional aerosol devices that inject upward, the drug does not diffuse to a high position, so that it is possible to prevent the drug from adhering to other than the target.
[0030]
Furthermore, since the shoulder cover 3 and the injection member 2 have a simple structure, they are inexpensive, highly reliable, and easy to operate. Further, there is an advantage that the conventional aerosol container can be mounted as it is without changing the design.
[0031]
In the present embodiment, the container 1 in a state where the injection member 2 and the shoulder cover 3 are mounted and the injection is started is placed on the stand 4. However, the injection member 2 is pushed in by being placed on the stand 4, and the injection is started. You may comprise as follows.
[0032]
The injection member 2 and the shoulder cover 3 or the shoulder cover 3 and the container 1 do not necessarily need to be firmly engaged. As a mechanism in which relative rotation occurs between the injection member 2 and the container 1 and only the injection member 2 rotates. Also good.
[0033]
FIG. 3 shows another embodiment of the aerosol device of the present invention.
[0034]
The present embodiment is characterized in that the stand 14 is formed from a small-diameter bar such as a steel wire in the embodiment of FIGS. On the upper surface of the stand 14, the bar forms a convex arc shape corresponding to the container 11 and the shoulder cover 13. By engaging a groove 13 d provided on the outer periphery of the shoulder cover 13 and an arc-shaped portion of the stand 14, the container 11 is held on the stand 14 in a rotatable state.
[0035]
4 and 5 show another embodiment of the aerosol device of the present invention.
[0036]
In the present embodiment, the stand 24 is attached to the container 21 via a hinge 26 and a bearing 27. The hinge 26 allows the stand 24 to be folded as shown in FIG. 4, which not only facilitates storage when not in use, but also prevents the ejection member 22 from being lost. In use, as shown in FIG. 5 (a), the stem is pushed in by raising the stand and attaching the injection member 22 to the connecting portion 28, and when this is placed on the floor or the like, R As shown by, the container 21 is jetted while rotating. In this embodiment, the container 21 is rotated by inclining the opening (injection direction) of the injection nozzle portion 22b with respect to the central axis of the container 21 as shown in FIG.
[0037]
Embodiment 2
Another embodiment of the aerosol device and the injection method of the present invention will be described with reference to FIGS.
[0038]
In the present embodiment, the aerosol device is composed of a container 51 enclosing a medicine and a spray button 53. The injection button 53 is provided with an intermittent injection mechanism.
[0039]
The operation of the intermittent injection mechanism will be briefly described. In the unused aerosol device, as shown in FIG. 6, the tip of the needle valve 54 fits into the inner periphery of the piston 57, and the flow path to the injection port 58 is closed. The injection button 53 is pushed in and meshed with the fixing means 53b. The stem 52 is pushed, and the high-pressure chemical flows into the pressure chamber 59. The piston 57 moves to the left in FIG. 6 due to the pressure of the medicine. Since the needle valve 54 is also dragged by the piston 57 and moves to the left, the flow path to the injection port 58 is still closed. Further, when the piston 57 tries to move to the left, the stepped portion of the rear end of the needle valve 57 comes into contact with the regulating member 56 and cannot follow the piston 57. The tip of the needle valve 54 is separated from the inner periphery of the piston 57, the flow path to the injection port 58 is opened, and the medicine is injected from the injection port 58.
[0040]
When the pressure in the pressure chamber 59 is reduced by the injection, the piston 57 is pushed back to the original position by the spring, and the injection is temporarily stopped. Thereafter, the pressure in the pressure chamber 59 is recovered, the piston 57 is moved again to the left, and injection is resumed.
[0041]
By the way, in this Embodiment, the elastic part is provided in the injection nozzle part 57a of piston 57 front-end | tip, and as shown in FIG. 6, the injection port 58 of front-end | tip of the injection nozzle part 57a has faced diagonally downward. Therefore, immediately after the start of injection, the medicine is injected obliquely downward and is injected and dispersed near the aerosol device. Thereafter, due to the reaction of the injection, the elastic portion of the injection nozzle portion 57a expands, and as shown in FIG. 7, the injection port 58 at the tip of the injection nozzle portion 57a faces slightly upward. The medicine is sprayed and dispersed at a position away from the aerosol device. When the medicine injection is stopped by the intermittent injection mechanism, the injection nozzle portion 57a returns to the position of FIG.
[0042]
Along with the operation of the intermittent injection mechanism, the injection nozzle portion 57a injects the medicine while performing a neck swinging operation as shown by the arrow S in FIG. 7, so that the medicine can be uniformly distributed over a wide range. it can.
[0043]
In addition, the injection nozzle part 57a may hang down diagonally downward due to gravity, or may be formed so as to face diagonally downward from the beginning. Alternatively, it may be initially formed so as to face upward, and the neck swinging operation may be performed downward by the reaction of injection. It is only necessary that deformation occurs in the injection nozzle portion 57a due to the reaction of the injection and the injection direction fluctuates.
[0044]
In order to achieve the purpose of preventing the adhesion to other than the target object while spraying the drug uniformly over a wide range, the diffusion range of the drug sprayed by the spray nozzle portion 57a is such that the elevation angle from the floor surface and the floor surface is It should be in a range between the surface of 70 ° or less.
[0045]
When the diffusion range is 70 ° or more from the floor surface, it becomes easy to be sprayed vertically upward with respect to the floor surface, the drug reaches a high position, and the drug adheres to an object to which the drug is not desired to adhere. End up.
[0046]
In addition, in consideration of prevention of inhalation into the human body and prevention of adhesion to a high position, it is desirable that the drug is diffused at a position lower than the chest or lower back of the human body, specifically 1.5 m or less, Is preferably 1.0 m or less, particularly preferably 0.8 m or less.
[0047]
According to the present embodiment, since the injection direction can be predicted and the medicine is not injected to the user side, it is possible to prevent an accident such as being applied to the user or being aspirated.
[0048]
【The invention's effect】
According to the aerosol device of the present invention, it is possible to uniformly inject a medicine over a wide range and prevent adhesion to other than the object.
[0049]
When a medicine is to be sprayed uniformly in a room or the like, it is not necessary to place it at the center of the room as in the conventional aerosol device of the type that sprays upward, and it may be placed at one corner of the room. An aerosol device is arranged in the vicinity of the entrance of the room so that the injection can be started and the room can be exited at the same time.
