BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol type injector which ejects bubbles and the like by a manual pushing operation.

[0002]

2. Description of the Related Art As is well known, an aerosol type injector is known.
For example, Freon gas is enclosed in a can container together with the contents,
By utilizing the vaporized pressure of this gas, it is possible to continuously inject bubbles etc. while the aerosol valve is opened by pressing down the pressing down head at the top, and recently from the viewpoint of environmental protection. Therefore, instead of Freon gas, pollution-free types such as those that utilize the pressure of citric acid and baking soda, or those that have improved pressure-accumulation cylinders have been developed and are emerging.

[0003]

The pressing head portion of the conventional aerosol-type injector for bubble injection or the like has a movable part having a nozzle tube communicating with an aerosol valve, a cap body for supporting the movable part, and It is composed of three parts such as a cover plate and other preventive members for preventing inadvertent depression of the movable part, and the number of parts is large, which requires labor for processing and assembling, resulting in a high cost.

The present invention is an aerosol-type injector in which a cap body, a movable part including a nozzle tube, and a push-down-preventing lock portion which constitute a push-down head portion are integrally formed by one-piece molding to reduce the cost. To get.

SUMMARY OF THE INVENTION The aerosol type injector of the present invention has a nozzle formed on the upper surface of a can body 1 having a top wall 4 formed by recessing a central band of a top wall 4 of a cap body 3 which is fitted and fixed by a peripheral wall 2. A tube storage chamber 5 is formed, and a peripheral wall 2 below the storage chamber 5 on one side of the storage chamber 5 is recessed inwardly 6 to form the storage chamber 5
From the other side of the bottom wall 7 to the vicinity of the recessed peripheral wall 6 can be pushed down by separating the other peripheral edge with the thin hinge 8 on the other side and communicating with the aerosol valve 9 projecting from the back side to the top of the can container body 1. And a reverse L-shaped push-down operation plate 12 that rises upward from the outer surface of one side portion of the peripheral wall 2 via a thin hinge 11 and bends to the upper surface of the storage chamber 5. A nozzle tube 14 having an abdominal portion joined to the end of the operation plate 12 through a thin hinge 13 is provided so as to be able to be erected. When the nozzle 14 is erected, the nozzle tube 14 is communicated with the communication tube 10, and when the nozzle 14 is laid down, it is stored in the storage chamber 5. It is configured to include a pressing head portion 16 which is housed and which cannot be pressed down by locking the tip end knob 15 and the base end of the nozzle tube 14 to the upper end of the peripheral wall 2 and the upper end of the concave peripheral wall 6, respectively.

[0006]

In the above, the tiltable nozzle tube 14 is normally laid down horizontally as shown in FIG.
In this housed state, the pipe mouth is closed by the peripheral wall 2, and the knob 15 at the tip of the pipe mouth rides on the upper end of the peripheral wall 2 and the base end on the upper end of the recessed peripheral wall 6, and is pushed down. Therefore, there is no possibility of inadvertently ejecting bubbles or the like.

At the time of injection, as shown in FIG. 2, the nozzle pipe 14 is erected by the knob 15 so that the base end opening of the nozzle pipe 14 is communicated with the communication pipe 10, and then the push-down operation plate 12 is pushed down. When lowered, nozzle tube 14, storage chamber bottom wall 7, communication tube 10
The movable part is pushed down to push down the aerosol valve 9 to open the valve, and bubbles or the like are ejected from the nozzle pipe 14 to the outside.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The present invention relates to an aerosol type injector, which includes a pressing head portion.
Movable part including 16 cap bodies 3 and nozzle tube 14 and knob
It is characterized in that 15 and the recessed peripheral wall 6, that is, each member of the push-down preventing member is formed by one-piece molding.

That is, in the pressing head portion 16 of the present invention, the central band of the top wall 4 of the cap body 3 is recessed downward to form the nozzle tube storage chamber 5 on the upper surface of the cap body 3, and the storage chamber is formed. 5 The peripheral wall 2 below the storage chamber 5 on one side is recessed inwardly 6
Then, from the other side of the bottom wall 7 of the storage chamber 5 to the vicinity of the recessed peripheral wall 6, it is possible to push down the other side by using the thin hinge 8 to separate the other peripheral edge and from the back side to the center of the top of the can container body 1. Communication pipe 10 that is fixed in communication with the protruding aerosol valve 9.
And a thin hinge from the outer surface of the one side portion of the peripheral wall 2.
An inverted L-shaped push-down operation plate 12 that rises upward through 11 and bends to near the center of the upper surface of the storage chamber 5 is erected.
It is an integrally molded product in which a nozzle tube 14 having a middle portion joined to the end through a thin hinge 13 is provided so as to be able to be erected. .

The nozzle can 14 has a rectangular outer shape corresponding to the storage chamber 5, and the end edge on the thin hinge 13 side of the tip opening is extended to form a knob 15 which also serves as a locking portion, and the base end is It is spherical.

On the other hand, when the upper surface of the bottom wall 7 of the storage chamber 5 on which the communication pipe 10 is hung is recessed into a spherical shape and the nozzle pipe 14 is erected and communicated with the communication pipe 10, this communication state is stable. To be held in.

Further, the cap body 3 has a concave peripheral wall 6 which is recessed inward in an L shape, and the horizontal wall is used to clamp the top peripheral edge of the can container body 1, and the cap body 3 is attached to the can container body 1. Is solid.

The aerosol type injector main body having the can container body 1 is one in which the content liquid is constantly pressurized by utilizing, for example, the vaporizing pressure of CFC gas, and the aerosol valve 9 is not shown. When a small amount of force is pushed down against the return spring, the valve opens while being pushed down so that the illustrated thin tube at the upper end communicates with the inside of the can container body 1, both of which are very well known and the present invention Since they are not directly related to the gist, their explanations are omitted.

In this embodiment, in the normal state of FIG. 1, the nozzle tube 14 accommodated in the horizontal state has the push-down operation plate 12.
In this stored state, the pipe mouth closes the peripheral wall 2, and the knob 15 and the base end of the nozzle tube 14 are locked to the upper end of the peripheral wall 2 and the upper end of the recessed peripheral wall 6, respectively. The tube 14 and the bottom wall 7 of the storage chamber 5 cannot be pushed down, and bubbles will not be inadvertently ejected.

In the state in which the nozzle pipe 14 is erected, the restraint of pushing down the nozzle pipe 14 and the bottom wall 7 is released. Therefore, when the pushing down operation plate 12 is pushed down, the nozzle pipe 14, the bottom wall 7 and the communication are communicated. Tube 10
Since the movable part of the nozzle lowers and the aerosol valve 9 is pushed down to open, bubbles are ejected from the nozzle tube 14 and this ejection continues during the pushing operation.

In the above embodiment, the aerosol type injector body may be a pollution-free type that does not use CFC gas, and the ejected matter may be a mist instead of a bubble.

[0017]

As described above, in the aerosol type injector of the present invention, the cap body 3 forming the push-down head portion 16, the movable portion including the nozzle tube 14 and the knob 15, the concave peripheral wall 6 are provided.
Since the locking part for preventing the push-down is formed by one-piece by integral molding, the processing is simplified, the management and assembling steps are omitted, and it is possible to greatly reduce the cost. Since the lower half portion is always located in the storage chamber 5, the tilting operation is performed by using the storage chamber 5 as a guide, so that the tilting operation is stable.
