Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a small manually operated sprayer.

"Prior Art" FIG. 1 shows an embodiment of the present invention, but since the atomizer mechanism itself is the same as in the conventional art, FIG. 1 will be borrowed for explanation.

In FIG. 1, 1 is a container body and 2 is a sprayer main body. The sprayer main body 2 includes a mounting screw cap 4 screwed onto the outer surface of the neck portion 3 of the container body 1, a small-diameter cylinder 5 integral with the screw cap 4, a guide cylinder 6, and a guide cylinder 6 slidably fitted therein. The inner hanging peripheral wall 7 is located at the top spray head 8 serving as a large-diameter cylinder, and at the axial center portion from the back surface of the spray head 8 to the upper part of the small-diameter cylinder 5, which is constantly pushed upward by the return spring 9 and the valve at the upper end. The portion 10 is provided with a movable communication member 13 that closes the liquid discharge passage 12 to the nozzle hole 11, and a suction pipe 15 that is fitted onto a small diameter connecting cylinder 14 at the lower end of the small diameter cylinder 5. In the figure, 16 is a suction ball valve, 17 is a small diameter piston, 18 is a large diameter piston, and 19 is a sealing cylinder member.

In FIG. 1, the spray head 8 and the movable portion of the movable communication member 13 are normally pushed upward by the return spring 9, and the valve portion 10 closes the liquid discharge passage 12. During spraying, the movable part is pressed against the return spring 9 via the spray head 8 to pressurize the liquid in the small diameter cylinder 5 below, and the pressurized liquid is passed through the communication groove 20 of the movable communication member 13 to the large diameter cylinder above. 7, the movable communicating member 13 is pushed down by the pressure difference based on the diameter difference between the pressurizing chambers of the both cylinders 5, 7 to open the discharge passage 12, and spray from the nozzle hole 11 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 mounting screw cap, so that 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 present invention is a suction pipe which is externally fitted and communicated with a cylinder 5 and a small diameter connecting cylinder 14 at the lower end of the cylinder 5 by a screw cap 4 screwed onto the outer surface of the neck 3 of the container body 1. A small atomizer in which the lower half of 15 is hung from the neck 3 portion into the container body 1 and the atomizer body 2 is attached to the mouth portion of the container body 1. In the small atomizer, a communication hole 20 is opened in the cylinder wall. An upper part of the withdrawal prevention member 21 is fixedly fitted into the mouth / neck part 3 so as not to be detachable, and the outer circumference of the cylinder 5 is hung down. When the cap 4 is loosened and the sprayer main body 2 is to be removed, the suction pipe 15 is detached and left in the container body 1 by the withdrawal blocking member 21 so that it cannot be reset.

[Operation] In the above, in the sprayer main body 2, the withdrawal prevention member 21 is temporarily set in the outer circumference of the cylinder 5, and in this state, the suction pipe 15 is externally connected to the small diameter connecting cylinder 14 at the lower end of the cylinder 5 to communicate with the container body 1. The screw cap 4 is disposed at the mouth portion and is screwed onto the outer surface of the mouth neck portion 3 of the container body. By this attachment, the extraction preventing member 21 is fixed to the mouth neck portion 3 side.

Here, when the screw cap 4 is loosened and the sprayer main body 2 is to be removed, the suction pipe 15 is prevented from being extracted by the extraction preventing member 21 fixed to the mouth / neck portion 3 side. As shown by the chain line in FIG. 1, the sprayer main body 2 is detached and left in the container body 1. This wicking pipe 15
Cannot be taken out of the container body 1 due to the withdrawal prevention member 21 being in the way. Therefore, even if the atomizer body 2 is reattached to the container body 1, the suction pipe 15 cannot be reset in the atomizer body 2 and the atomizer sprays. It will stop functioning, lose commercial value,
It will not be distributed as a product.

[Embodiment] An embodiment will be described below with reference to the drawings. In the present invention, the present invention is arranged on the outer circumference of a cylinder 5 in the lower half of the atomizer body 2 and is attached to the mouth of the container body 1 together with the body 2. It is characterized in that a withdrawal blocking member 21 is provided, and after the atomizer main body 2 is removed by this withdrawal blocking member 21, the product cannot be reset and the reliability of the product is improved.

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.

As shown in FIG. 2, the pull-out preventing member 21 is composed of a lower throttle cylinder body having a plurality of communication holes 20 formed in the lower part of the cylinder wall in the circumferential direction, and has an outward flange 22 at the upper end thereof. ,
Engagement ridges 23 are provided on the outer surface of the intermediate portion near the upper part, and are molded and manufactured from synthetic resin.

As shown in FIG. 1, the withdrawal prevention member 21 is temporarily arranged in the lower half of the sprayer main body 2 by surrounding the lower end opening end face of the suction pipe 15 with the upper end opening end face of the suction pipe 15. In this state, the sprayer body 2 and the sprayer body 2 are fitted in the mouth / neck portion 3 of the container body 1.

The lower end of the inner surface of the mouth / neck portion 3 of the container body 1 is cut off in an angular shape, and a downward step portion 24 is formed in this portion, and the screw cap 4 is screwed onto the outer surface of the mouth / neck portion 3 and tightened to form the sprayer main body 2. When the withdrawal blocking member 21 is mounted in the mouth / neck part 3, the outwardly facing flange 22 at the upper end of the withdrawal blocking member 21 is hooked on the top surface of the mouth / neck part 3, and at this time, the engaging projection 23 is located at the lower end of the mouth / neck part 3. The upper and lower ends of the mouth / neck portion 3 are sandwiched by engaging with the downward step portion 24, and the mouth / neck portion 3 is firmly fitted and fixed in the mouth / neck portion 3. 25 indicates packing.

Therefore, if the screw cap 4 is loosened and the sprayer main body 2 is removed in order to replace the contents in the container body 1, the suction pipe
Reference numeral 15 is a withdrawal prevention member 21 fixed to the container body 1 neck 3
Withdrawal is prevented by and is left in the container 1 as shown by the chain line in FIG. Since the lower end portion of the withdrawal prevention member 21 has the same diameter as the suction pipe 15, the withdrawal prevention member 2 cannot be taken out of the suction pipe 15 due to the hindrance, and therefore the sprayer main body 2 is temporarily put in the container body 1 again. Even when attached, the suction pipe 15 cannot be set, the sprayer cannot have a spraying function, and it cannot be distributed as a product.

[Advantages of the Invention] As described above, in the small-sized sprayer of the present invention, the withdrawal prevention member 21 which is a cylindrical body of the lower throttle located in the outer circumference of the cylinder 5 by being fixedly fitted in the container body 1 neck 3 irremovably. Is provided, the lower end of the blocking member 21 is abutted against the upper end of the suction pipe 15, and when the sprayer main body 2 is to be removed, the extraction blocking member 21 causes the suction pipe 15 to remain in the container body 1 and is reset. Since it has been made impossible, it is possible to effectively prevent tampering that does not replace the contents inside the container body 1, and it is possible to enhance the reliability of the product.
