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 air is ejected from the head. 2. Description of the Related Art A small perfume atomizer is known in which liquid inside a container is sucked out through a suction pipe vertically installed inside the container, 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 4 is attached to the upper end of the container body, and an elastic hollow sphere 19 is attached to the head, and when the hollow sphere is squeezed, the air inside the sphere is released. The liquid is pressurized and ejected from the nozzle hole 23 of the head, and the ejection creates a negative pressure in the liquid suction path opened at the base end of the nozzle hole, and the suction pipe 18 is suspended from the head into the container body. In a small atomizer, a through hole 11 is provided in the front-rear direction of the head, and the inner diameter of the front part of the through hole is set to 1. The air supply pipe 20 having the elastic hollow sphere 19 attached to the rear end of the pipe part is fixed through the through hole, and the front part of the air supply pipe is connected to the hole 22 of the screw 21. A screw 2 with a hole is loosely inserted into the first large inner diameter screw hole 12.
1, the rear parts are screwed together, a nozzle hole 23 is bored in the center of the front end surface of the hole 22, and the gap formed between the inner surface of the hole 22 and the outer surface of the air supply pipe is connected between the suction pipe and the nozzle hole. By screwing in the screw 21, the front end surface of the hole and the front end surface of the air supply pipe are brought into close contact with each other, and the opening portion of the liquid suction path to the base end of the nozzle hole is watertightly closed. It was formed like this.

"Operation" When the screw with hole 21 is loosened from the illustrated state, the front end surface of the hole and the front end surface of the air pipe are separated, and the suction pipe hole, the pipe fitting hole 16, the through hole 11, and the air pipe 20 are separated.
The liquid suction path formed by the gap between the hole 22 and the air supply pipe communicates with the nozzle hole 23. Therefore, when the elastic hollow body 19 is squeezed in this state, the pressure inside the hollow body is increased. Air is supplied through the air pipe hole 20a
and is ejected to the outside of the head through the nozzle 23. Due to this ejection, the pressure at the nozzle hole side opening of the liquid suction path becomes negative, so that the liquid inside the container is sucked out through the suction pipe 18, mixed with the ejected air, and sprayed. After spraying, screw with hole 21
When tightened, the liquid suction passage opening is watertightly closed.

"Example" 1 is a container body in which a threaded neck part 2 is made to stand up from the upper end of a body part 3.

The head has a short cylindrical shape with a spherical upper surface, and has a main body 7 with an outward flange 6 attached to the outer periphery of the lower end, and a flange hole of an inward flange 8 attached to the upper end of the peripheral wall 5. It is formed by a peripheral wall member 9 which is inserted through the container body and whose peripheral wall is screwed to the container body neck, and a packing 10 is sandwiched between the outer periphery of the lower surface of the main body and the container body neck. A through hole 11 is bored in the front and back direction of the main body, and the front and rear portions of the through hole are first and second large inner diameter screw hole portions 12 and 13, and the first large inner diameter screw hole portion is a first large inner diameter screw hole portion. 1
The front half of 2 further forms a large inner diameter hole 15 via a forward step 14. A pipe fitting hole 16 is provided on the central axis in the vertical direction of the main body so as to communicate with the through hole 11 from the lower end surface of the main body, and an air hole 17 is provided from the lower end surface of the main body with the front end surface opened in the forward step portion 14.
has been drilled. The upper end of a suction pipe 18 is fitted into the pipe fitting hole 16, and the pipe is vertically disposed within the container body.

Inside the through hole 11, an air supply pipe 20 having an elastic hollow sphere 19 attached to the rear end of the tube is passed through from the rear of the through hole to the front, and a screw portion 20 is formed at the rear of the tube.
a is screwed into the second large inner diameter screw hole portion 13. The front end surface of the tube portion is formed into a tapered surface.

Inside the first large inner diameter screw hole portion 12 is a screw with a hole 21.
Screw the rear part together. The screw has a hole 22 tapered from the rear end surface to the front end surface on its central axis, and a nozzle hole 23 is opened in the front surface of the screw from the center of the front end surface of the hole. is inserted loosely. The first half of the screw is formed into a large outer diameter portion 24 that fits into the large inner diameter hole 15 described above, and an O-ring 25 is fitted on the outer periphery of the rear end of the large outer diameter portion. The screw 21 is provided so that when tightened, the front end surface of the air pipe and the front end surface of the hole 22 come into airtight contact, and the rear end surface of the large outer diameter section 24 airtightly closes the front end surface of the air hole 17. When loosened, the pipe fitting hole 16 and the nozzle hole 23 pass between the through hole 11 and the hole 22 and the air pipe 20, and the pipe fitting hole 16 and the nozzle hole 23 pass between the first large inner diameter screw hole 12 and the screw 21 and the hole 22. The air hole 17 and the nozzle hole 23 communicate with each other through the space between the air pipe 20 and the air pipe 20 .

In the illustrated embodiment, an air hole 1 is provided to prevent negative pressure inside the container when the liquid inside the container decreases.
