Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a small atomizer mainly used for perfumes.

``Prior art'' A spray head is attached to the upper end of the container body, and an elastic hollow sphere is attached to the head, and when the hollow sphere is squeezed, the air inside the sphere is jetted out from the nozzle hole of the head. The ejection creates a negative pressure in the liquid suction passage opened at the base end of the nozzle hole, and the liquid inside the container is sucked out from the head through the suction pipe vertically installed inside the container, and the liquid is mixed with the ejected air. Small atomizers for perfumes are known which are arranged to atomize by mixing.

``Problems to be solved by the invention'' Conventionally, the above-mentioned small sprayers do not have a mechanism for opening and closing the nozzle holes, and for this reason, if the sprayer falls over, liquid leaks from the nozzle hole, and even if the sprayer does not fall over, the nozzle hole The disadvantage was that the liquid fragrance vaporized through the process.

In this case, a stopper for opening and closing the liquid passage is attached to a part of the liquid passage leading from the suction pipe to the nozzle hole, and a ventilation passage for sucking outside air is provided in a part of the stopper, and the ventilation passage and the liquid This invention relates to a sprayer that can simultaneously open and close passages in one operation.

"Means for Solving the Problem" A spray head is attached to the upper end of the container body, and an elastic hollow sphere is attached to the head, and when the hollow sphere is squeezed, the air inside the sphere is released from the nozzle hole of the head. The ejected air creates a negative pressure in the liquid suction path opened at the base end of the nozzle hole, and the liquid inside the container is sucked out from the head through the suction pipe vertically installed inside the container, and the ejected air and In this small sprayer, the spray head is fitted with a lower part of the mounting cylinder part 16 on the outer surface of the container mouth neck part 17, and a thick top wall installed horizontally on the upper part of the mounting cylinder part. A vertical hole communicating with the suction pipe 6 is bored in the center, and a horizontal hole 9 is bored in the top wall thereof, intersecting the vertical hole and opening at least one end face to the top of the mounting cylinder 16. a mouth member 7, a head body 2 with the elastic hollow sphere 3 into which the upper part of the mouth member is fitted, and a rod-shaped switching plug with a knob rotatably fitted into the horizontal hole 9. 13, and the horizontal hole 9
An intake hole 10 communicating into the container body 1 is formed in the bottom wall of the container body 1, and the vertical hole and the intake hole are formed in the axially intermediate portion and outer surface of the rod-shaped switching plug 13 by rotating the rod-shaped switching plug. A through-hole 11 and an outside air suction groove 12 communicating with 10 were provided, respectively.

"Operation" When the rod-shaped switching plug 13 is rotated by a predetermined angle using the knob 14 from the state shown in FIG. When the elastic hollow sphere 3 is elastically squeezed, the liquid inside the container is sprayed from the nozzle hole, and the outside air is sucked into the container. When the rod-shaped switching plug 13 is rotated from this state, as shown in FIG.
The upper end surfaces of the vertical hole and the intake hole 10 are closed by the outer surface of the rod-shaped switching plug.

Embodiment First, the embodiment shown in FIGS. 1 and 2 will be described. Reference numeral 1 denotes a synthetic resin container body with a threaded mouth and neck portion 17 erected from the upper end of the body.

A synthetic resin spray head is attached to the outer surface of the mouth and neck portion 17. The spray head is formed by a mouth member 7, a head body 2, and a rod-shaped switching plug 13.

The mouth member 7 has a mounting cylinder part 16 whose lower part is screwed into the aforementioned mouth neck part 17, and a vertical hole is bored in the center of a thick top wall installed horizontally in the upper part of the mounting cylinder part. The upper part of the suction pipe 16, which is vertically disposed within the container body, is fitted into the inner surface of a pipe holding cylinder which is vertically disposed from the lower edge of the vertical hole. Further, a horizontal hole 9 is bored inside the top wall, intersecting with the vertical hole and having a rear end opening at the top of the mounting cylinder 16, and an intake hole 10 communicating into the container body 1 is formed at the rear of the bottom wall of the horizontal hole. is installed. Furthermore, first and second connecting cylinder parts 19 and 20 are erected from the upper surface of the top wall.

The head main body 1 has a lower part fitted into the first and second connecting cylinder parts 19 and 20 described above, and a screw hole 5 with an opening on the rear end face is bored in the upper part, and an elastic hollow sphere 3 is inserted into the screw hole. The front part of the air pipe attached to the rear end is screwed together. The outer diameter of the front part of the air supply pipe is reduced to provide a gap between the front inner surface of the screw hole 5, the upper end is opened in the gap part, and the lower end is connected to the cylindrical hole 8 of the first connecting cylinder part mentioned above.
A communicating hole opening at the upper end is bored in the front part of the bottom wall of the screw hole 5. Note that 4 is a nozzle hole bored in the front end wall of the screw hole 5.

The rod-shaped switching plug 13 is rotatably fitted into the above-mentioned horizontal hole 9, and by rotating the rod-shaped switching plug, the above-mentioned vertical hole and the intake A through hole 11 and an outside air suction groove 12 communicating with the hole 10 are provided, respectively. Further, an engagement protrusion 22 is provided around the rear outer surface of the rod-shaped switching plug 13, and the engagement protrusion 22 is engaged in an engagement groove formed at the rear end of the inner surface of the above-mentioned horizontal hole 9. Further, a plate-shaped knob 14 is vertically provided from the rear end of the rod-shaped switching plug 13. The knob may have a U-shape as shown in FIG. 4. In this case, both ends of the horizontal hole 9 are opened to allow a rod-shaped switching plug to pass through, and a U-shaped knob 14 is inserted at both ends of the plug. Connect both ends.

Note that 15 indicates packing.

"Effect of the invention" The present invention has the above configuration, and the mouth member 7
A rod-shaped switching plug 13 with a knob 14 is rotatably fitted into the horizontal hole 3 bored in the top wall of the rod-shaped switching plug 13, and the rod-shaped switching plug 13 is rotatably fitted in the axially intermediate portion and outer surface of the rod-shaped switching plug. By doing so, the vertical hole and the intake hole 10
Since the through hole 11 and the outside air intake groove 12 are provided to communicate with each other, by rotating the rod-shaped switching plug 13, the vertical hole and the through hole 11, and the intake hole 10 and the outside air intake groove 12 can be made to communicate at the same time. At the same time, by rotating the rod-shaped switching plug 13 again from this state, the vertical hole and the upper end surface of the intake hole 10 can be closed at once by the outer surface of the rod-shaped switching plug. Since the vertical hole and the intake hole 10 can be opened and closed at the same time, it is easy to use and extremely convenient.
