On the contrary, if the front / rear slide part 23 is moved forward, the front nozzles 10f, 10f of the nozzle members 10, 10 are moved away from each other via the connecting members 12, 12.
This has already been explained above.

  FIG. 4 shows a state in which an injection guide tube is further connected to the injection port of the injection port member of the injection mechanism according to the above-described embodiment, and (A) is a cross-sectional view taken along the line A-A in FIG. Is a perspective view.

  The injection guide tube 40 shown in this figure has a Y-shape in a plan view, and is formed of a tube body having a conduction path therein, and forms a distal end nozzle hole with the connecting portions 41 and 41 on the base end side of the fork. It has a nozzle part 42.

In this embodiment, the nozzle hole 42 is provided with a nozzle tip 42t.
As the nozzle tip 42t, there are various types, but a chip suitable for obtaining a desired injection form may be used.

  In the injection guide tube 40, the injection ports of the injection port members 10 and 10 are connected in a state where the injection port members 10 and 10 are appropriately brought closer to the inner side of the angle. Of course, it is also possible to connect the connecting portions 41, 41.

In this case, it is only necessary to provide a bifurcated angle and extend the base end connecting portions 41 and 41 substantially in parallel.
As described above, by using the injection guide tube 40, the two contents are mixed from the nozzle portion 42 at the tip of the injection guide tube 40 in a state where the contents inside the aerosol containers K and K are mixed in advance. Can be injected into the outside world.

While the embodiments of the present invention have been described above, various design changes can be made in the present invention as follows.
The injection mechanism according to the present invention can be applied not only to the aerosol container but also to a pump type injection container.

Also in this pump-type injection container, as with the valve stem of the aerosol container, there is an injection stem in which the content liquid is injected from the pump, and the injection mechanism according to the above embodiment can be adapted to this injection stem as it is. Because it can.
First of all, in the present invention, the above-described cap member can be carried out without providing it.

  In other words, the operation member has a shaft supporting portion of two connecting members on the upper surface thereof, and if the operation member can be pressed down, the pair of right and left injection port members can be pressed down through these connecting members. It is because it can fully exhibit.

  Of course, a cap member is provided and the front end of the operation member is pivotally connected to the front surface of the cap member so that the gripping portion of the cap member can be gripped by hand and the rear end of the operation member can be easily pushed down. Is better.

In the above-described embodiment, the cap member with the top portion opened is employed. However, the top portion may be closed without opening in this way.
In this case, the internal structure can be hidden, and the product can be commercialized as a smarter one.

  The form of the injection port member can also be freely changed in design, the point is that a conduction path is formed inside, and the inlet part which is the base end part thereof is the valve stem of the aerosol container and the injection stem of the pump type injection container. What is necessary is just to connect and make the exit part of the conduction path into a nozzle hole, and the external appearance shape can also be changed suitably.

The connecting member is also in a rod-like or plate-like long shape, and any shape may be used as long as the pair of members can be pivotally supported by the central shaft support portion.
The shaft support portion only needs to be provided on the upper surface portion of the operation member, and the operation member only needs to have a form that can simultaneously press down the pair of injection port members on both sides and move in the front-rear direction. .

In the above embodiment, the front / rear slide portion is provided on the upper surface of the operation member, and the center side end portion of the connecting member is pivotally supported by the front / rear slide portion. However, the operation member may be implemented without the front / rear slide portion. .
In that case, the operation member itself needs to be configured to move back and forth.

  Further, in the above embodiment, the front end portion of the operation member is rotatably connected to the front surface portion of the cap member, but by adopting this configuration, the operation of pushing down the rear end portion of the operation member can be more reliably performed. It is easy.

The shape of the injection guide tube can also be freely changed in design. In short, the conduction path is formed inside, the base end side is formed in a bifurcated shape and can be connected to the injection port of the injection member, and the injection port is formed at the tip. Any form may be used as long as the part is formed.
A separate nozzle hole tip may be fitted to the tip of the tip to have various types of injection forms.

  The injection guide tube can be configured to be connected when the connected injection port members are in a substantially parallel state or when the injection port of the injection member is approaching.

  Furthermore, the injection guide tube can be implemented as a form that can be connected regardless of the direction of the injection port of the injection member by adopting a flexible material that can be plastically deformed. .

Finally, in the present invention, it is specified as an injection mechanism of two injection containers, but this shows the minimum components, and even if there are three or more injection containers, this injection mechanism It is possible to apply.
This is because if three injection containers are connected, an operation member is provided on the injection port member connected to the injection stem of the central injection container, and the operation member is slid rearward to slide the left and right sides. This is because the injection port member may be configured to be rotatable, and the operation member may be configured to simultaneously press these three injection port members.

  Further, if there are four injection containers, an operation member is arranged at an intermediate position between the two injection stems in the center, and the operation member at the center position is slid rearward to press down, thereby four injection port members. This is because it is sufficient that the nozzle hole is directed toward the center and all the nozzles are pressed simultaneously.

  As described above, in the present invention, the injection angle of the nozzle holes of the pair of nozzle members can be changed and adjusted, and the contents in the two spray containers can be mixed and spray applied at a position away from the nozzle by a predetermined distance, or Thus, it is possible to provide an injection mechanism capable of connecting the injection guide pipes to these injection holes and injecting the contents in the two injection containers in advance.
