During spraying, the movable part is pressed against the return spring 12 via the spraying head 11 to pressurize the liquid in the small diameter cylinder 7 below, and the pressurized liquid is passed through the communication groove 23 of the movable communication member 16 to the large diameter cylinder above. It is sent to the inside of 10, and the movable communication member 16 is pushed down by the pressure difference based on the diameter difference between the pressurizing chambers of both cylinders 7 and 10, the discharge passage 15 is opened, and sprayed from the nozzle hole 14 to the outside.

"Problems to be solved by the device" In this type of small sprayer, the sprayer main body can be removed from the container body by removing the screw cap for mounting, so mischief is performed to replace the contents of the drug etc. in the container body with water etc. Sometimes.

The present invention is to obtain a small-sized sprayer having a mounting structure in which the sprayer main body is once set in the container body and then cannot be reset when it is removed, thereby enhancing the reliability of the product.

[Means for Solving the Problems] The small sprayer of the present invention is a small sprayer of the present invention. The sprayer main body 2 that is hung from inside the container body 1 and attached to the mouth of the container body 1 and the suction pipe 8 that hangs down inside the container body 1 are connected and fixed so that they can be detached from the lower end opening of the cylinder 7. Fitted coupling tube 3
When the sprayer main body 2 is removed via the screw cap 6, the connecting cylinder 3 is detached from the cylinder 7 part, and the withdrawal prevention member 4 for leaving the connecting cylinder 3 and the suction pipe 8 in the container body 1. When the screw cap 6 is loosened and the sprayer main body 2 is to be removed, the suction pipe 8 is removed and left in the container body 1 by the extraction blocking member 4,
It cannot be reset.

[Operation] In the above, the sprayer main body 2 is attached to the mouth portion of the container body 1 by screwing the screw cap 6 onto the outer surface of the mouth / neck portion 5, and therefore can be removed by loosening the screw cap 6.

However, when the sprayer body 2 is once mounted and then is to be removed, the connecting cylinder 3 is prevented from being pulled out by the pulling-out preventing member 4 and is separated from the sprayer body 2, so that the main part of the sprayer body 2 can be taken out. The integrated body of the coupling cylinder 3 and the suction pipe 8 is left in the container body 1.

Therefore, even if the atomizer main body 2 is reattached to the container body 1, the connecting cylinder 3 with the suction pipe 8 cannot be reset in the atomizer main body 2, and the atomizer loses its spraying function and loses its commercial value. , Will no longer be distributed as a product.

[Embodiment] The embodiment of the present invention will be described with reference to the accompanying drawings. In the present invention, a suction pipe 8 is detachably connected to a cylinder 7 through a connecting cylinder 3 and an extraction preventing member 4 is provided. The removal blocking member 4 is characterized in that when the atomizer main body 2 is removed, the connecting cylinder 3 and the suction pipe 8 are detached to form a mounting structure that cannot be reset, thereby improving the reliability of the product.

Since the present invention is not directly related to the spray mechanism, and the sprayer main body 2 has been described above and is very well known, the description other than the characteristic parts will be omitted.

First Embodiment (FIGS. 1 and 2) In this embodiment, the connecting cylinder 3 has a large diameter part 3a having the same diameter as the connecting cylinder 17 at the lower end of the cylinder 7 and a small diameter in the upper half part. Part 3b
The suction pipe 8 is fitted and fixed to the lower half large diameter portion 3a, and the small diameter portion 3b is detachably fitted to the connecting cylinder 17 so that the suction pipe 8 communicates with the cylinder 7. Further, the pull-out preventing member 4 is formed by a pair of reverse piercing pieces 4a, 4a capable of being squeezed inward from both sides of the lower half large diameter portion 3a of the coupling cylinder 3 and obliquely projecting obliquely upward and outward. The integrated body of both is molded and manufactured from a synthetic resin material.

Therefore, the withdrawal prevention member 4 including the reverse puncture pieces 4a, 4a is
Since the container body mouth / neck part 5 is forcibly slid and the container body mouth / neck part 5 is slid, the sprayer main body 2 can be mounted on the container body 1 as shown in FIG. There is a pair of barbs 4a, 4a on the shoulder 24 of the container body 1.
Since the main body of the sprayer main body 2 can be removed, the combined body of the connecting cylinder 3 and the suction pipe 8 cannot be taken out to the outside, and the main body of the sprayer main body 2 is detached from the sprayer main body 2 and the container body 1 is removed. It remains inside and cannot be reset.

Second Embodiment (FIG. 3, FIG. 4, FIG. 5) In this embodiment, the coupling cylinder 3 has a lower half portion 3a as a small diameter portion and an upper half portion 3b as a large diameter portion. The large diameter part 3b has a shape in which the ratchet mechanism engagement pieces 3c, 3c are provided on both sides of the outer surface, and the small diameter part 3b
The suction pipe 8 is fitted and fixed to a, and the large-diameter portion 3b is screwed to the connecting cylinder 17 by screwing the thread groove on the inner surface into the thread 25 of the connecting cylinder 17 of the cylinder 7.

On the other hand, the extraction preventing member 4 has an outward flange 26 at the upper end.
Is a shape in which a rod portion provided with locking pieces 28, 28 protruding inward is hung from both sides of the lower end of a cylindrical body provided with engaging projections 27 on the outer surface of the intermediate portion toward the upper side, and an outward flange. 26 is hooked on the top surface of the mouth / neck of the container body 5, and the engaging projection 27 is engaged with the downward step of the lower end of the mouth / neck 5 so that it cannot be detached from the mouth / neck 5 by pre-clamping and fixing. The locking pieces 28, 28 at the lower end are located at the meshing pieces 3c, 3c of the connecting cylinder 3.

That is, since the meshing pieces 3c, 3c bend due to the force in the screw tightening direction, the sprayer main body 2 can be mounted on the container body 1 even if the pre-squeeze extraction preventing member 4 is mounted, but once. When installed, if the screws are loosened in the opposite direction, the mating pieces 3c, 3
Since c is locked by the locking pieces 28, 28 and the connecting cylinder 3 does not rotate, when the sprayer main body 2 is removed by loosening the screw cap 6, the combined body of the connecting cylinder 3 and the suction pipe 8 is the sprayer main body. It is detached from No. 2 and left in the container 1 and cannot be reset.

In this embodiment, the locking pieces 28, 2 of the extraction preventing member 4 are
