Description

[Detailed description of the invention] The present invention relates to a piercing injection aerosol device used for spraying aerosol contents such as insecticides into tatami mats, inside carpets, into wood, etc. Various types of aerosol devices are used, but the needle-shaped nozzle comes into contact with the target object, or the stem is pushed in the valve opening direction during the insertion process into the target area, and the nozzle is opened at the target area. The spraying of the aerosol contents may start before the target object reaches the object, and the surface of the target object may be contaminated, or the aerosol contents may not be sprayed to the correct location.

The present invention eliminates the above-mentioned drawbacks, and allows the connection pipe, which is positioned with an appropriate distance between the connection port and the stem, to be moved in the axial direction of the cap when the cap is fitted and fixed to the aerosol container. A needle-like nozzle for piercing the target part is connected to one end of this connecting tube, and the needle-shaped nozzle does not connect with the stem during the process of piercing the target part, so that it can be pressed easily after the piercing is completed. Therefore, the stem and the connecting port are connected, and the connecting tube is biased toward the piercing part with a biasing force that can push the stem in the valve opening direction, and when the cap is fixed to the aerosol container, it is connected to the needle nozzle. The connection port is located at an appropriate distance from the stem, and the aerosol contents can only be injected by strong pressure after the needle nozzle has been inserted to the injection destination.
The aerosol contents can be properly injected to the target area without wasting the aerosol contents, and the surface of the target area will not be contaminated.

An embodiment of the present invention will be described below with reference to the drawings. 1 is an aerosol container, a mounting cup 2 is fixed to the upper end of the container in an upright position, and the internal valve mechanism is connected from the center of the mounting cup 2. The connected stem 3 is protruding. A fitting part 6 of a cap 5 is removably fitted and fixed to the seaming part 4 of the aerosol container 1, and a retaining wall 8 is protruded from the outer surface of the top plate 7 of the cap 5, and a rotating part is provided between the retaining walls 8. The rotating body 11 is fixed by supporting the fixed shafts 10 on both sides as much as possible, and the connecting pipe 12 is inserted into the rotating body 11 so as to be slidable in the axial direction, and the protruding portion 13 in the stem 3 direction also serves as a stopper. A connection port 14 is provided, and this connection port 14 is located at an appropriate distance from the stem 3 when the cap 5 is fitted and fixed to the aerosol container 1. A needle-like nozzle 15 for partial piercing is connected so as to be able to inject the aerosol contents. In addition, the connecting pipe 12 has a locking flange 16 formed on the outer periphery.
A spring 17 is interposed between the spring 17 and the rotating body 11, and the urging force of the spring 17 is applied when the needle-like nozzle 15 is pressed against the injection object 18 such as tatami mats, carpets, and wood, or when the injection object 18 is During the insertion process, stem 3
The connecting port 14 is connected to the stem 3 by the pressing force applied to the locking collar 16 after the insertion of the protrusion is completed, and the aerosol contents can be injected. . Further, the needle-like nozzle 15 has an ejection hole 21 for the aerosol contents formed on the side surface in the direction of the tip 20, and a protector 22 is slidably inserted into the outer periphery. The needle-like nozzle 15 is pressed and energized by the weak spring 23, and the sharp tip 20 of the needle-like nozzle 15 is always covered to prevent it from coming into contact with and injuring human hands, etc., and also to prevent the needle from being inserted into the injection object 18. and finally press the connecting pipe 12 as shown in FIG. Further, in the above embodiment, the connecting pipe 12 to which the needle nozzle 15 is connected is connected directly to the stem 3, but in other different embodiments, the push button can be used as shown in FIGS. 4 and 5. 2
It may also be connected to the stem 3 via 4.

When the aerosol container 1 is not in use, the rotating body 11 is rotated from the fixed shaft 10 to house the needle nozzle 15 between the retaining walls 8 of the cap 5 and protrude outward as shown in FIG. In addition, during injection use, the rotary body 11 can be rotated about the fixed shaft 10 and protruded outward from the cap 5 for use. In addition, since the rotary body 11 and the cap 5 are supported by the fixed shaft 10, the aerosol device having the needle nozzle 15 can be used completely without being separated from the cap 5 and being lost. That is.

Since the present invention is constructed as described above,
When the cap is fixed to the aerosol container,
The connection port that connects to the needle nozzle is placed at an appropriate distance from the stem, and the aerosol contents can only be sprayed by applying strong pressure after the needle nozzle has been inserted to the injection target area. Therefore, the aerosol contents can be correctly injected to the target area without wasting the aerosol contents, and the surface of the target area will not be contaminated.

Claims (1)

[Scope of utility model registration request] When the cap is fitted and fixed to the aerosol container, a connecting pipe is formed on the cap so that the connecting port is positioned at an appropriate distance from the stem, and is movable in the axial direction. While connecting the needle nozzle, there is no connection with the stem during the process of inserting the needle nozzle into the target part, and the stem and connection port are connected by pressing after the needle is inserted, and the stem is moved in the valve opening direction. What is claimed is: 1. An aerosol device for puncture injection, characterized in that a connecting tube is biased toward a puncture portion by a biasing force capable of pushing the connecting tube toward the puncture portion.
