Description

[Detailed Description of the Invention] A. Purpose of the Invention Industrial Application Field The present invention relates to a sprayer equipped with a safety cap for preventing the spray head from being pushed down.

BACKGROUND OF THE INVENTION Sprayers are widely used in various fields. As is well known, this sprayer has a spray head at the top, and by pushing down the spray head against a return spring, a discharge passage is opened, thereby allowing the pre-pressurized stored liquid to flow into the spray head. The spray is ejected from the nozzle of the spray head through a passage, and for safety reasons, the head cannot be pushed down except when spraying.

However, many conventional devices of this type are detachable each time they are used, and are often lost.

Problems to be Solved by the Invention In view of the above-mentioned points, the present invention aims to provide a sprayer that can achieve the intended purpose without being removed during spraying and is equipped with a safety mechanism that eliminates the above-mentioned drawbacks.

B. Structure of the invention Means for solving the problems The sprayer of the present invention has a safety cap 3 erected from the upper end of the container body 2 of the sprayer main body 1 so as to extend the body 2 upward. A key-shaped space 5 is cut out from the top surface above the spray head 4 to the upper back, and a nozzle hole 6 of the spray head 4 is cut out.
An engaging piece 8 that can be folded forward with a flexible hinge 7 is formed on the upper front surface facing the head, and a stopper 9 protrudes from the rear surface of the lower part of the engaging piece 8 to support the lower surface of the spray head 4 and prevent it from being pushed down. It is said that

Effect In the above, normally as shown in Figures 1 and 2,
The engagement piece 8 is in an upright state and its stopper 9 supports the lower surface of the spray head 4, so the spray head 4 cannot be pushed down and no liquid can be sprayed out.

Here, when spouting the liquid, the engaging piece 8 is pushed down using the flexible hinge 7 as a fulcrum as shown by the two-dot chain line in FIG. All you have to do is push down the spray head 4 using the operating section.

Embodiment The sprayer main body 1 is well known and has no direct relation to the gist of the present invention, so a description thereof will be omitted here. Of course, the liquid pressurizing means of the sprayer main body 1 may be of a manual pump type or an aerosol type.

The safety cap 3 has an engaging protrusion 10 on the inner periphery of the lower end.
The engaging protrusion 10 is fitted and fixed to the engaging protrusion 11 on the upper end of the container body 2. If the engagement piece 8 of the safety cap 3 is always unstable in its attached state, appropriate measures may be taken. For example, the left and right edges of the engaging piece 8 may be fitted into the fixed peripheral wall of the cap 3 a little more firmly, or in some cases, a stopper with an engaging protrusion may be used. This is possible using known mechanisms.

Each of the above parts is molded and manufactured from synthetic resin material.

C. Effects of the invention According to the invention, a notch 5 is provided as a push-down operation part from the top surface above the spray head 4 of the safety cap 3 erected from the upper end of the container body 2 to the rear side, and the nozzle is An engaging piece 8 having a stopper 9 for preventing the spray head 4 from being pushed down is formed on the front face facing the hole 6 so that it can be folded forward, and the engagement piece 8 is folded down only during spraying to release the blocking of the spray head 4 from being pushed down. This makes it safe, and since there is no need to remove the safety cap 3 in this case, there is no risk of it being lost.Furthermore, it is easy to operate by simply folding down the engaging piece 8, and there is no trouble at all. In addition, only one safety cap 3 is required as a part, and since this cap 3 has a simple shape, it is structurally simple.
Can be provided at low cost.

Claims (1)

[Scope of utility model registration request] From the upper end of the container body 2 of the sprayer main body 1 to this body 2
A safety cap 3 is erected so that it extends upward, and a key-shaped cavity 5 is cut out from the top surface above the spray head 4 of the safety cap 3 to the top of the back, and the nozzle hole 6 of the spray head 4 is cut out. This sprayer has an engaging piece 8 that can be folded forward by a flexible hinge 7 at the upper part of the facing front surface, and has a stopper 9 protruding from the rear surface of the lower part of the engaging piece 8 to support the lower surface of the spray head 4 and prevent it from being pushed down.
