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 this head. When this hollow sphere is squeezed, the air inside this sphere is pressurized and the nozzle of the head is The liquid is ejected from the hole, and this ejection 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 a suction pipe vertically installed inside the container. Small atomizers for perfumes are known which are arranged to atomize by mixing with the above-mentioned ejected air.

``Problems to be solved by the invention'' Conventionally, the above-mentioned small sprayers do not have a mechanism to open and close the nozzle, so if the sprayer falls over, liquid will leak from the nozzle hole, and even if the sprayer does not fall over, this nozzle The drawback was that the liquid fragrance vaporized through the holes.

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

``Means for Solving the Problems'' In the small sprayer of the present invention, a spray head 2 is attached to the upper end of a container body 1, and an elastic hollow sphere 3 is attached to the head 2. When squeezed, the air inside the sphere 3 is pressurized and ejected from the nozzle hole 4 of the head 2, and this ejection creates a negative pressure in the liquid suction passage 5 opened at the base end of the nozzle hole 4. In a small sprayer, the liquid in the container body 1 is sucked out from the head 2 through a suction pipe 6 vertically installed inside the container body 1, and is sprayed by mixing with the above-mentioned ejected air. A horizontal hole 7 is formed that communicates with the rear side, and a feed tube 9 that is always pushed toward the nozzle hole 4 side by a return spring 11 and closes the liquid suction path 5 is slidably inserted into this horizontal hole 7, while an elastic hollow hole 7 is formed. The sphere 3 is attached to the rear end of the sending cylinder 9 by means of an integral joint 8 whose side surface is in contact with the back surface of the head 2, and which is normally upright together with the sphere 3. Point 10 with a large distance between
When the sphere 3 and the joint 8 are bent horizontally, the joint 8 communicates with the sending cylinder 9, and the joint 8 pulls the sending cylinder 9 back against the return spring 11. , is characterized in that the liquid suction passage 5 is communicated with the nozzle hole 4.

"Operation" Normally, as shown in Figure 1b, the integral body of the elastic hollow sphere 3 and the joint 8 is erected upward, and in this state, the air supply path from the hollow sphere 3 side to the supply cylinder 9 is disconnected.
Further, the sending cylinder 9 is pushed toward the nozzle hole 4 side by a return spring 11, and the inclined surface A at its tip comes into pressure contact with the inclined surface around the back surface of the nozzle hole 4, thereby cutting off the liquid suction passage 5.

Here, to spray, use the hollow sphere 3 as shown in the arrow.
and joint 8 are brought into a horizontal position. Then, this integrated body communicates with the sending cylinder 9, and in this case, since the distance between the pivot point 10 of the joint 8 and the side end of the sending cylinder 9 is larger than that between the side, the sending cylinder is connected via this joint 8. 9 is pulled back against the return spring 11, and the liquid suction passage 5 communicates with the nozzle hole 4. After this, the elastic hollow sphere 3 may be compressed.

``Example'' The example shown in Figures 1 and 2 is the same as that described in the ``Means for solving the problem'' mentioned above, and in order to avoid duplication, the above described part is Explanation will be omitted, and only matters not mentioned above will be explained.

The spray head 2 is connected to the container body 1 through the packing 12.
The mouth-neck part 13 is placed on the top surface of the mouth and is firmly fixed by an attachment cap 15 screwed onto the mouth-neck part 13 via a flange 14 on the lower outer surface.

The area around the back of the nozzle hole 4, which is the tip of the horizontal hole 7 opened in the spray head 2, is an inclined surface corresponding to the inclined surface A at the tip of the sending cylinder 9. These inclined surfaces are in close contact with each other, so that the liquid suction path 5 can be cut off. The rear half of the horizontal hole 7 has an enlarged diameter, and a return spring 11 is arranged in this enlarged diameter part, and an intake groove 16 that communicates with the outside is formed on the rear side of the lower surface, and communicates with this enlarged diameter part. Let the intake hole 17
is provided through the lower surface of the head 2, and furthermore, the rear exit portion of the horizontal hole 7 is covered with a rigid end plate 18 made of metal.

A mounting screw 19 is fixedly attached to the air supply port of the elastic hollow sphere 3. This mounting screw 19 has a ventilation hole 20 in the shaft core, and has a flange 21 on the proximal end, and is airtightly fitted to the mouth of the sphere 3 at the flange 21, and the distal end has a disc-shaped part 22. It is formed in

The joint 8 is a short cylindrical body whose diameter part is cut off in the distal half to form a forked shape, and a screw hole 23 is bored in the shaft center of the proximal half. The opening pivot points 10, 10 are each screw holes, and screws 2
4 and 24 can be screwed on. The tips of the screws 24, 24 are simply small diameter shafts.

The feed cylinder 9 has a diameter portion on the rear end side cut out into a disk shape, and holes 26, 26 are formed on both sides of this portion 25.
Further, a flange 27 is provided on the outer surface of the intermediate portion, and the tip end surface is an inclined surface A.

In the above, the elastic hollow sphere 3 is integrated with the joint 8 by screwing the mounting screw 19 into the screw hole 23, while the rear end of the sending cylinder 9 is inserted into the forked part of the joint 8, and the hollow part 25 Disk-shaped part 22 at the tip of the mounting screw 19
is inserted, and in this state, the screws 24, 24 are screwed into the pivot points 10, 10, and the small diameter shafts at the ends of the screws 24, 24 are loosely inserted into the holes 26, 26, so that the feed cylinder 9 is pivotally attached. . However, the sending cylinder 9 is packing 28
It is disposed in the horizontal hole 7 through a flange 27 and is always urged toward the nozzle hole 4 by a return spring 11.

That is, when the sending cylinder 9 and the elastic hollow sphere 3 are in a straight line at the joint 8, they communicate with each other, and when they are bent by 90 degrees at the joint 8, they are out of communication.

Incidentally, when the liquid suction passage 5 is cut off in FIG.
6 is cut off, the intake passage is cut off, and when the feed tube 9 is pulled back and the liquid suction passage 5 is opened during spraying, the flange 27 also moves rearward and closes the intake groove. 16 and the suction hole 17 communicate with each other to open the suction path, thereby preventing negative pressure in the container body 1 from being sucked in as the liquid is poured out.

In the above, the return spring 11, end plate 18, screw 2
All parts except 4 and 24 are made of synthetic resin.

"Effects of the Invention" As described above, in the present invention, a mechanism for opening and closing the nozzle hole 4 is provided, and this opening and closing mechanism allows the nozzle hole 4 to be opened and closed.
Since the nozzle hole 4 is closed at all times and opened during spraying, it is possible to conveniently prevent the evaporation of the fragrance passing through the nozzle hole 4 and the outflow of the fragrance when the container falls over. Moreover, the operation of the opening/closing mechanism is a one-touch operation of raising and lowering the elastic hollow sphere 3 approximately 90 degrees, which is simple and does not require any trouble.
