(See Japanese Patent Application Laid-Open No. 6-100049).

[0004]

However, in such a conventional ejector, the mixing chamber 3 is not ejected from the nozzle 8 before it is ejected.
While a plurality of contents are mixed in a, the contents generally tend to solidify when mixed, so that the mixing chamber 3 is used after use.
There has been a problem that the mixed content remaining in a may be solidified with the passage of time and the nozzle 8 may be clogged.

In the above-described conventional ejector, when the ejection button 2 is tilted and pressed down, the bottles 7A and 7B
There is a problem of consuming one of the contents in one side.

Accordingly, a first object of the present invention is to eliminate the possibility that the contents are solidified and the nozzle is clogged in the ejector of the type in which a plurality of contents are mixed and jetted as described above. It is in.

[0007] A second object of the present invention is to eliminate the risk of consuming one of the plurality of contents by one way depending on how the ejection button is pushed down in such an ejector.

[0008]

Accordingly, the present invention provides
In order to achieve the above-described first problem, in an ejector that presses down a spray button at the time of use and simultaneously sprays a plurality of contents to be stored separately in a container from a nozzle of the spray button, a nozzle is used for each content. The nozzles are individually provided, and the ejection areas of these nozzles are overlapped.

The present invention can be applied to a pump type ejector, in which a pump is operated by depressing an ejection button, and a plurality of contents in a container are pumped up and ejected from a nozzle. Further, the present invention can be applied to an aerosol type ejector, in which a spray button is depressed to open each valve, and a plurality of contents in a container can be respectively ejected from a nozzle by the pressure of the ejection material in the container.

[0010] In order to achieve the above-mentioned second object, it is preferable that each of the conductive paths for guiding the contents from the container to the spray button is provided concentrically with the spray button at the same center line.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a central longitudinal section of the ejector according to the invention. As shown in the drawing, the ejector according to the present invention is, for example, a vertically long circular can-shaped container 10.
The pump 12 is attached to the opening.

Although not shown, the first contents are put in the container 10, and the second contents are put in the bag 14 attached to the lower part of the pump 12 and put in the container 10. Inflate.

An injection button 16 is mounted on the upper part of the pump 12. The ejection button 16 includes a first nozzle 18 and a second nozzle 20 in upper and lower stages. And the cap 22 is covered.

When using this ejector, the cap 2
2 is removed, and the nozzles 18 and 20 are directed to the object to be sprayed with the contents. Then, as shown in FIG.
6 is pushed down, and the ejection pipe 30 is pushed in.

Then, the first piston 32 is pushed down together with the second piston 34, the space between the first piston 32 and the first on-off valve 36 is opened, and the pressure in the first pressure chamber 38 is increased with the ejection pipe 30 being pushed down. The first content in the first pressure chamber 38 is passed through the space between the first on-off valve 36 and the first piston 32 to form a first groove-shaped first groove formed on the inner surface of the ejection pipe 30.
Put in the conduction path 40.

Then, the injection button 1 is
6 into the annular vertical ejection path 42, from the vertical ejection path 42 to the annular lower horizontal ejection path 44, and into the injection port 4 of the first nozzle 18.
Inject in the range of 6 to A.

On the other hand, when the second piston 34 is depressed, the space between the second on-off valve 48 is opened, and when the second piston 34 is depressed, the pressure in the second pressure chamber 50 is increased.
The second content in the pressure chamber 50 enters the communication passage 54 in the second piston 34 through the communication hole 52.

Then, the first piston 32 is
Into the vertical ejection path 58 at the center of the injection button 16 from the second conduction path 56, and into the annular upper horizontal ejection path 60 from the vertical ejection path 58. Inject in the range from 62 to B.

At this time, the injection area A from the injection port 46 of the first nozzle 18 and the injection area B from the injection port 62 of the second nozzle 20 overlap the area indicated by C. Most of the contents ejected from 18.20 are mixed and sprayed on the target site.

In this example, the nozzles 18 and 20 spray in the form of a mist, but the invention is not necessarily limited to the case where the spray is performed in the form of a mist.

When the hand is released from the injection button 16 after the injection, the first piston 3 is pushed by the urging force of the coil spring 70.
The second and second pistons 34 move upward to lift the ejection pipe 30 and return the ejection button 16 to its original position.

At this time, the space between the first piston 32 and the first on-off valve 36 is closed, the first piston 32 is moved upward, the pressure in the first pressure chamber 38 is reduced, and the first check valve 72 is opened. The first content contained in the container 10 is sucked into the first pressure chamber 38 through the suction port 74 of the pump 12.

When the hand is released from the injection button 16, at the same time, the space between the second piston 34 and the second on-off valve 48 is closed,
With the upward movement of the second piston 34, the pressure in the second pressure chamber 50 is reduced to a negative pressure, the second check valve 76 is opened, and the second content stored in the bag 14 is passed through the suction port 78 of the pump 12 to the second The liquid is sucked into the pressure chamber 50.

Thus, when the ejection button 16 is depressed again, the contents can be repeatedly ejected from the nozzles 18 and 20.

In the illustrated example, the first conductive path 40 for guiding the first content from the container 10 to the spray button 16 is provided.
Are provided around a second conduction path 56 for guiding the second content from the bag 14 in the container 10 to the injection button 16, and the respective conduction paths 40 and 5 for guiding the content from the container 10 to the injection button 16.
6 is provided concentrically with the ejection button 16 and the center line O.

Thus, the ejection button 16 can always be pushed straight down from directly above to eliminate the possibility of being pushed down by tilting. It is possible to eliminate the risk of eccentric consumption.

In the example described above, the present invention is applied to the case where the injection button 16 is depressed to operate the pump 12 and the container 10
Each of the multiple nozzles is pumped and the individual nozzles 1
The case where the present invention is applied to a pump type ejector ejecting from 8.20 has been described.

However, in the present invention, although not shown, an aerosol-type ejector in which a plurality of contents in a container are ejected from a nozzle by the pressure of the ejection material in the container, respectively, by depressing an injection button to open each valve. In addition, the present invention can be similarly applied by separately providing nozzles for each content and overlapping the ejection regions of those nozzles.

In the above-described example, the case where the first and second types of contents are mixed has been described.
Not only the type but also three or more types can be similarly applied by separately providing nozzles for each content and overlapping the ejection regions of those nozzles.

[0030]

Therefore, according to the present invention, the nozzles are individually provided for the respective contents, the ejection areas of the nozzles are overlapped, and the plurality of contents are mixed only after the ejection from the nozzles. It is not necessary to mix a plurality of contents before spraying from the nozzle, for example, to provide a mixing chamber, and the contents that are likely to be solidified by mixing remain in the mixing chamber, for example, and the mixed contents are solidified, and the mixed contents are visually observed by the nozzle. The conventional problem that causes clogging can be solved.

Further, the present invention is appropriately selected according to the application, and as in the invention according to the second aspect, the injection button is depressed to operate the pump, and the plurality of contents in the container are respectively pumped up and the nozzle is discharged from the nozzle. Also in the pump type ejector for ejecting, as in the invention according to claim 3, each valve is opened by depressing the ejection button, and a plurality of contents in the container are respectively discharged from the nozzle by the pressure of the ejection material in the container. The present invention can also be applied to an aerosol type ejector that ejects.

According to the fourth aspect of the present invention, since each of the conductive paths for guiding the contents from the container to the spray button is provided concentrically with the spray button at the same center line, the spray button is always positioned from directly above to below. , So that there is no danger of tilting and pushing down, and even if there is a possibility of tilting and pushing down, there is no danger that any of the plurality of contents will be consumed in a biased manner.
