[0001]
[Industrial application fields]
The present invention relates to an aerosol device for limited-range injection for injecting aerosol contents to a specific range, mainly when spraying or applying a medicine to the nose, mouth, eyes, etc. of the human body. Is particularly effective.
[0002]
[Prior art]
Conventionally, there are aerosol drugs for spraying the human eye, mouth, nose, etc., but when these aerosol drugs are sprayed on the human body, they are widely diffused by the spray pressure of the aerosol other than the target part of the human body. In some cases, the surroundings are contaminated, or an unfavorable situation occurs in a human organ other than the target part. In particular, when an irritating drug such as a mouth freshener for injection into the mouth adheres to the eyes or the like that are close to the mouth, there is a possibility of causing strong discomfort or injury.
[0003]
[Problems to be solved by the invention]
Therefore, in the present invention, it is possible to inject the aerosol contents limited to the target portion to be injected. Further, in the present invention, it is possible to prevent the surroundings from being contaminated in the injection of the aerosol contents. In other words, since the spraying is performed in a state in which the specific target portion, mouth, nose, eyes, etc. of the body are completely covered with the covering cover, the aerosol contents that have come into contact with the body such as the mouth, nose, eyes, etc. It will not fall and spread around. Therefore, after the aerosol content has been ejected, the aerosol content ejection operation can be completed only by discarding the content liquid accumulated in the covering cover and washing it lightly.
[0004]
[Means for Solving the Problems]
The present invention is to solve the such problem described above, the outer periphery of the nozzle body to perform the injection of the aerosol contents, to form a plurality of engagement step portions having different heights at the axial direction of the nozzle body in a stepwise manner An aerosol container and an insertion port through which the nozzle body of the aerosol container is removably inserted are provided, and an engagement protrusion that engages with the upper surface of any of the plurality of engagement steps is formed on the inner surface of the insertion port. And an adapter provided with a cover that communicates with the insertion port and covers the spray target portion of the aerosol contents.
[0005]
Further, another different invention is provided with an aerosol container having an engagement protrusion formed on an outer periphery of a nozzle body for injecting aerosol contents, and an insertion port through which the nozzle body of the aerosol container is removably inserted. the inner surface of the insertion port, the aerosol contents communicated with the insertion hole with the engaging step portion of different multiple heights formed stepwise to be engaged with the engaging projection and at the axial direction of the insertion opening And an adapter provided with a covering cover for covering the jetting target portion of the object.
[0006]
The covering cover may be formed in a shape that can cover the shoulder cover of the aerosol container.
[0007]
[Action]
Since the present invention is configured as described above, in order to inject the aerosol contents to an appropriate injection target portion, the covering cover is brought into close contact with the injection target portion such as the mouth, nose, and eyes of the human body. In this contact state, the stem of the aerosol container is pressed, the control valve is opened, and the contents are ejected from the nozzle of the nozzle body.
[0008]
In this spraying, since the covering cover covers the spray target portion, the aerosol content does not diffuse around, and the aerosol content can be reliably sprayed and applied to the spray target portion. In addition, the aerosol contents that have flowed out or dropped off from the injection target section do not fall into the covering cover and diffuse around. Therefore, in the case of aerosol contents that spray a certain amount, as in the case of washing the nose, eyes, and throat, the aerosol contents that have undergone such washing flow out into the covering cover and are kept in the covering cover. It will be drunk. Therefore, the aerosol contents are not diffused around, and the aerosol contents can reliably reach the injection target portion and can be injected to the injection target portion.
[0009]
Further, a plurality of engaging step portions having different heights are formed on the outer periphery of the nozzle body connected to the stem of the aerosol container. And since the engaging projection is formed in the insertion port of the adapter through which this nozzle body is inserted, the adapter is attached to the nozzle body by engaging the engaging projection with one of the engaging stepped portions. On the other hand, the vertical arrangement can be advanced and retracted. And since it becomes possible to adjust the distance of the nozzle of the nozzle body with respect to the injection target part, according to the content prescription of the aerosol content, the situation of the injection target part, the user's preference, etc., the nozzle and the injection target part It is possible to arbitrarily adjust the distance.
[0010]
Therefore, if it is necessary to spray the aerosol contents strongly according to the purpose of use, the nozzle body may be inserted deeply into the adapter and engaged. In addition, when a relatively loose and gentle injection is performed on the target part, the distance between the injection target part and the nozzle can be increased by shallowly engaging and fixing the adapter and the nozzle body. .
[0011]
In addition, since the engagement protrusion and the engagement step portion are relative, a plurality of engagement protrusions are formed on the outer periphery of the nozzle body, and the engagement protrusions are engaged with the inner surface of the insertion port. It is good also as what forms an engagement step part.
