The nozzle 0, the nozzle 70, and the cap with nozzle 90 are each formed of a synthetic resin material.

Next, the operation of the present embodiment will be described.
In order to eject bubbles, the body 2 may be squeezed, and the liquid in the body 2 rises in the suction pipe 40 to separate the first valve plate 53 upward from the bottom plate 33, thereby forming a water-gas mixing box 50. At the same time, the air in the body 2 also flows into the water / water mixing box 50 from the second air inlet 37 through the ventilation path 54 as a number of bubbles.

Many bubbles generated in the water-mixing box 50 are made uniform when passing through the foaming mesh 55 and flow out of the water-mixing box 50. The bubbles flowing out of the water-mixing box 50 are ejected from the nozzle cylinder 73 from the discharge cylinder 15 through the first and second outflow windows 16 and 71. When the nozzle 70 is not provided, the bubbles flowing out of the water-mixing box 50 are
Eject directly from 5.

After the squeezing, the body 2 returns to its original shape due to its elastic force, and the inside of the body becomes negative pressure.
3 flows into the outside air suction gap passage 52 through the discharge cylinder 15, and further flows into the body 2 from the first intake hole 36 while separating the second valve plate 56 downward from the annular bottom wall 14.

Next, measures for preventing inadvertent foam ejection will be described. In order to disable the bubble ejection, the cap 90 with the nozzle is moved from the state shown in FIG.
And the second engagement plate 94 is moved forward by the first
Since the base is separated from the engagement plate 19 and engages with the rear first engagement plate 20 and the base end surface of the nozzle tube 73 is closed by the discharge tube 15, bubbles are ejected from the nozzle tube 73 even when the body 2 is squeezed. Never do.

In order to enable foam ejection, the cap 90 with the nozzle may be rotated in the opposite direction to the above.
When rotated by 80 °, the second engagement plate 94 is moved to the front first engagement plate 1.
No further rotation is possible due to the engagement with 9. In this non-rotatable position, the nozzle tube 73 is in communication with the discharge tube 15 via the first and second outflow windows 16 and 71 as shown in FIG.

[0023]

According to the first to fourth aspects of the present invention, each of the first valve plate capable of opening and closing the suction hole, the elastic second valve plate capable of opening and closing the outside air suction gap, and the foaming mesh are mixed. Since the number of parts is reduced by being provided integrally with the box, assembly costs can be reduced and parts management can be facilitated.

According to the third aspect of the present invention, since the cap with the nozzle is rotatably provided so as to be able to cut off the communication between the inside of the nozzle cylinder and the inside of the container, it is possible to prevent inadvertent blowing of bubbles. Since the engagement positions of the first engagement plate and the second engagement plate correspond to the bubble dischargeable position and the non-foamable position, it is easy to determine the positions of these positions. The invention according to claim 4 is
Since all members are formed of a synthetic resin material, sorting and discharging becomes easy.
