Description

[Detailed description of the invention] "Industrial Application Field" This 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.
When the hollow sphere is squeezed, the air inside the sphere is pressurized and ejected from the nozzle hole of the head, and this ejection creates a negative pressure in the liquid suction passage opened at the base end of the nozzle hole, and the liquid is drawn out from the head into the container. 2. Description of the Related Art A small perfume atomizer is known in which a liquid inside a container is sucked out through a suction pipe installed vertically inside the body, and the liquid is mixed with the above-mentioned ejected air and sprayed.

``Problems to be solved by the invention'' The above-mentioned small atomizer does not have a nozzle hole opening/closing device, so if the atomizer falls down, liquid will leak from the nozzle hole, and even if the atomizer does not fall down, the liquid fragrance will vaporize. It was hot.

The present invention eliminates these drawbacks and makes it possible to easily close the nozzle hole.

"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 pressurized. The liquid is ejected from the nozzle hole of the head, and the liquid suction path opened at the base end of the nozzle hole is made negative pressure, and the liquid flows from the head through the suction pipe vertically installed inside the container body. In a small atomizer, the liquid is sucked out and atomized by mixing with the ejected air.The head 4 is provided with a screw hole 10, the tip of the hole is communicated with the base end of the nozzle hole 11, and the liquid is mixed with the ejected air. Threaded hole 1
A tubular screw 16 is screwed into the inside of the hollow elastic sphere 20 so that the tube hole 17 of the tubular screw communicates with the inside of the elastic hollow sphere 20. When the tubular screw 16 is screwed in, the tip surface of the tubular screw comes into contact with the tip surface of the screw hole 10, and the liquid suction path portion formed by the gap between these two tip surfaces is formed by the gap between the two tip surfaces. It was formed to be sealed.

"Operation" When the tubular screw 16 is screwed in, the tip end surface of the screw comes into contact with the tip end surface of the screw hole 10, and the liquid suction path formed by the gap between these two end surfaces is sealed. When the tubular screw is unscrewed from this state, the liquid suction passage portion opens and spray can be made by squeezing the hollow sphere 20 in this state.

Embodiment A first embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 denotes a container body in which a threaded neck portion 2 stands up from the upper end of a body portion 3.

A peripheral wall 5 of a spray head 4 is screwed into the neck of the container body. A packing 7 is provided between the inwardly flange-shaped shoulder 6 at the upper end of the peripheral wall and the top surface of the container body. The inner peripheral edge of the shoulder portion is connected to the lower end peripheral edge of the bullet-shaped portion 8, and an O-ring 9 is fitted to the outer periphery of the opening at the vertically intermediate portion of the bullet-shaped portion 8 to form a threaded hole 1.
0 is bored, the end surface of the hole is a first tapered surface, and a nozzle hole 11 is opened from the center to the outer surface of the bullet-shaped portion. Further, on the axis of the bullet-shaped part, a screw hole 12 is bored from the bottom surface of the bullet-shaped part with the upper end opening into the screw hole 10, and the upper part of the screw tube 13 is screwed into the screw hole. The suction pipe 14 is vertically disposed within the container body with its upper end fitted into the threaded hole. The upper end of the air hole 15 is opened immediately below the opening of the screw hole, and the lower end of the air hole is opened at the bottom surface of the bullet-shaped portion 8 to communicate with the inside of the container.

A tubular screw 16 is screwed into the screw hole 10. The tubular screw has a tube hole 17 on its axis, and has an outward flange 18 on the outer surface of the intermediate portion of the tubular screw, so that the lever 1 can be inserted from a part of the outer surface of the flange.
9 protrudes outward. Further, a screw is provided in the tubular screw portion on the distal end side of the outward flange, and the screw is screwed into the threaded hole 10, and the distal end surface of the tubular screw becomes a second tapered surface, and by screwing it, the above-mentioned first tapered surface is formed. and the second tapered surface are provided in close contact with each other. Further, when screwed in, the outward flange 18 closes the upper opening surface of the air hole 15.
The mouth of an elastic hollow sphere 20 is fitted into the rear end of the tubular screw 16, and by squeezing the hollow sphere, the pressurized air inside the sphere is discharged from the nozzle hole 11 through the tube hole 17 of the tubular screw. . It is preferable to attach an intake valve 21 to the hollow sphere 20. If no intake valve is provided, outside air will be taken in through the nozzle hole and the tube hole of the tubular screw. The liquid suction path is formed by the suction pipe, the screw hole 12, the screw hole, and the gap between the tubular screws.

In the second embodiment shown in FIG. 4, the spray head 4 is
Bullet-shaped part 8 and cap-shaped part 5 for screwing together the container mouth and neck
a, and these two members are fixed together by a connecting means 5b. Further, in this embodiment, the lever 19 is not provided, and the rear part of the tubular screw is formed into a bent pipe shape, so that the screw can be screwed in by rotating the bent part.

``Effect of the invention'' Since the present invention has the above-described structure, the liquid suction path can be opened and closed, and the liquid inside the container can be prevented from leaking or vaporizing due to blockage after use. The opening and closing can be done by tightening or loosening the tubular screw to which the elastic hollow sphere 20 is attached, so it can be done easily and quickly, and since the mechanism is simple, it can be manufactured at low cost.
