Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to spraying means for an aerosol device for spraying aerosol contents such as pesticides and pesticides.

[0002]

2. Description of the Related Art Conventionally, in order to process aerosol contents at a high place, a user holds a rod having a nozzle attached to its tip with one hand and places the nozzle high, and the user holds the aerosol with the other hand. Operate the buttons and levers on the device to
The aerosol contents were sprayed from the nozzle.

[0003]

In the conventional spraying method,
Both hands of the user are blocked and the work is complicated. The present invention has been made in view of the above circumstances, and an object thereof is to provide a spraying device for an aerosol device that can easily spray an aerosol content to a high place even by one-handed operation.

[0004]

The object of the present invention is achieved by the following constitution. (1) A first nozzle unit that is attached to an aerosol container provided with a stem and directly or indirectly communicates with the stem, a telescopic rod, and a second attached to a part of the telescopic rod. A jet nozzle unit, a flexible tube connecting the first jet nozzle unit and the second jet nozzle unit, and a part of the telescopic rod that is provided above the aerosol container and extends upward when in use. And a rod holder capable of holding the other portion of the telescopic rod. (2) A cap attached to an aerosol container provided with a stem, a first nozzle unit provided in the cap and directly or indirectly communicating with the stem, a telescopic rod, and a part of the telescopic rod. A state in which the attached second ejection port unit, a flexible tube connecting the first ejection port unit and the second ejection port unit, and a part of the telescopic rod that is provided in the cap and extends upward when in use And a rod holding portion capable of holding the other portion of the telescopic rod. (3) The rod holding portion is capable of holding the other portion of the telescopic rod so that the telescopic rod does not extend to the outer peripheral side of the aerosol container and extends vertically. Alternatively, the spray means for the aerosol device according to (2). (4) The spray device for an aerosol device according to any one of (1) to (3), wherein the rod holding part has a holding hole into which the other part of the telescopic rod is inserted. (5) The spray device for an aerosol device according to any one of (1) to (3), wherein the rod holding part has a screw hole into which the other part of the expandable rod is screwed. (6) The atomizing means for an aerosol device according to (1), wherein the rod holding portion has a holding cylinder in which the telescopic rod slides. (7) The spray device for an aerosol device according to (1), wherein the rod holding part holds the other part of the telescopic rod so as to be rotatable about the other part. (8) The aerosol device according to any one of (1) to (7), wherein when the flexible tube is not connected to the first nozzle unit, the aerosol content can be sprayed from the first nozzle unit. Spraying means. (9) Switching for switching between spraying the aerosol content from the first nozzle unit or the second nozzle unit with the flexible tube connected to the first nozzle unit and the second nozzle unit The atomizing means for an aerosol device according to any one of (1) to (7) above, which is provided with a valve. (10) An aerosol device comprising the aerosol device spraying means according to any one of (1) to (9).

Usually, the cap of the spraying means for the aerosol device has a high degree of freedom in shape because it is molded from synthetic resin. Therefore, it is relatively easy and inexpensive to provide the cap with the rod holding portion as described above. For example, instead of providing the rod holding portion on the cap, when trying to provide the rod holding portion on the side portion of the aerosol container, since the aerosol container is usually a metal can and the degree of freedom of the shape is low,
The rod holding portion is provided by adding another member made of synthetic resin or the like. This causes an increase in the number of parts and an increase in cost. Then, by holding the other part of the rod, part of which is provided with the second nozzle unit, on the rod holding part provided on the cap, the aerosol contents are sprayed to a high place only by operating the button or lever with one hand. You will be able to. Moreover, the spray position can be easily changed by adjusting the length of the telescopic rod. Further, if the rod holding portion can hold the other portion of the telescopic rod so that the telescopic rod does not extend to the outer peripheral side of the aerosol container and extends vertically, the operability is further stabilized. The inner diameter of the flexible tube is 1.5 to
It is preferably 3.5 mm, more preferably about 2 mm. In addition, the injection port diameter (jet port diameter) in the first or second injection port unit is preferably 0.5 to 1.6 mm, more preferably about 1 mm.
