Description

[Detailed description of the invention] The present invention relates to a needle-shaped aerosol nozzle used for spraying aerosol contents such as insecticides into tatami mats, carpets, etc. Various types of aerosol nozzles have been used, but because the aerosol nozzles are sharp, they may injure the user's hands, which is particularly undesirable when the aerosol content is an insecticide or the like.

The present invention eliminates the above-mentioned drawbacks, and includes a covering body slidably inserted around the outer periphery of a needle-shaped jet pipe whose one end communicates with the nozzle of an aerosol nozzle, and one end of the covering body being inserted into the outer periphery of the needle-shaped jet pipe, one end of which is connected to the spout of the aerosol nozzle. Under pressure, it protrudes outward from one end of the needle-like ejection pipe to cover the tip of the needle-like ejection pipe, and when one end of the covering is pressed, it slides around the outer periphery of the needle-like ejection pipe against the restoring force of the spring. The needle-like ejection tube is made to be able to protrude from one end of the covering, and when not in use, the tip of the needle-like ejection tube is covered with one end of the covering, so that the user's hand, etc. comes into contact with the tip. When one end of the covering is pressed against the injection target part, the covering slides along the outer periphery of the needle-like ejection pipe and can protrude from one end of the covering of the needle-like ejection pipe into the injection target part. This makes it possible to safely use an aerosol nozzle having a needle-like ejection tube.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an aerosol container, a mounting cup 2 is fixed to the upper end, and a stem 3 is connected from the center of the mounting cup 2 to an internal valve mechanism. stands out. Reference numeral 4 designates a push button connected to the stem 3, the outer periphery of which is covered by a one-touch cap 5 fixed to the mounting cup 2, and a spout 6 provided on one side for spraying the aerosol contents. The pipe 7 projects into the fitting recess 8, and a threaded groove 9 is formed on the outer periphery of the ejection pipe 7. Reference numeral 11 denotes a connecting body, one end of which is connected to the screw groove 9 of the ejection pipe 7 so as to be attachable and detachable, and a magnet 12 is attached to the outer surface of one side for fixing it to the outer periphery of the aerosol container 1 when detached, as shown in FIG. It is fixed and forms an ejection path 13 for the aerosol contents from one end to the other end. Reference numeral 14 denotes a needle-shaped ejection tube, one end of which is connected to the ejection path 13 and has an ejection hole 16 for the aerosol content formed on the side surface in the direction of the tip 15, and a covering 17 is slidably inserted around the outer periphery. Spring 18 interposed between body 17 and connection body 11
With a pressing force of
A needle-like ejection pipe 14 protrudes outward from one end of 4.
When the covering body 17 is pressed at one end, it slides on the outer periphery of the needle-like ejection pipe 14 against the restoring force of the spring 18, and the needle-like ejection pipe 14 is
As shown in the figure, the cover 17 is formed to protrude from one end so that the needle-like ejection tube 14 can be inserted into the object 20 to be ejected.

In the above embodiment, the connecting body 11 to which the needle-shaped ejection pipe 14 is connected is screwed to the outer periphery of the ejection pipe 7, but in other different embodiments, it can be fitted as shown in FIG. The outer periphery of the connecting body 11 may be screwed onto the inner periphery of the recess 8.

Since the present invention is constructed as described above,
When not in use, the tip of the needle-shaped ejection tube is covered with one end of the covering, so that the user's hand does not come into contact with the tip, and when one end of the covering is pressed against the object to be sprayed, the needle-shaped The covering is slid along the outer periphery of the jetting pipe, so that the needle-shaped jetting pipe can be projected into the injection target from one end of the covering pipe,
This enables safe use of an aerosol nozzle having a needle-like ejection tube.

Claims (1)

[Scope of utility model registration request] A covering is slidably inserted into the outer periphery of a needle-like ejection tube whose one end communicates with the nozzle of the aerosol nozzle, and one end of this covering is projected outward beyond one end of the needle-like ejection pipe by the pressing force of the spring. It covers the tip of the needle-like ejection tube, and when one end of the covering is pressed, it slides on the outer periphery of the needle-like ejection pipe against the restoring force of the spring, so that the needle-like ejection pipe can protrude from one end of the covering. An aerosol nozzle characterized by:
