FIG. 3 shows a second embodiment of the first embodiment of the present invention as a partial sectional view. In FIG. 3, portions denoted by the same reference numerals as in FIG. 2 have the same structure as in FIG. 2, and the basic operation of the pump-type foam ejector is the same as that described in FIG. In this embodiment, only the bubble passage of the upper cap 17 formed above the piston shaft 9 is changed from that of FIG.
A bubble passage is opened directly above in the axial direction, and a nozzle 19 is fitted into the bubble passage to discharge the bubble obliquely downward from above the tip of the nozzle 19 to store the bubble in the bubble receiving tray 15. By pushing down the head of the nozzle 19 instead of the push rod shown in FIG. 2, bubbles are similarly discharged.

The upper cap 17 shown in FIG. 3 is provided with a skirt-shaped overhang portion 18 having an annular projection formed on its outer periphery and a female screw formed on its inner peripheral surface. By fitting the inner peripheral surface of the hollow cylinder 21 formed in the center part on the back side, the foam receiving tray 15 is attached to the upper cap 17. As described above, the nozzle 19 and the foam tray 15 are fitted to the upper cap 17 by fitting, but since these parts are made of synthetic resin, they can be easily attached and detached by applying a slightly stronger force. Therefore, at the time of shipping or the like, the package can be packed with the nozzle 19 and the foam tray 15 removed from the upper cap 17, and the bulk can be reduced.

A male screw 2 is attached to the neck of the intermediate cap 10.
0 is provided, and a female screw is formed on the inner peripheral surface of the skirt-shaped overhang portion 18 of the upper cap 17. When not in use, the two screws are screwed together with the upper cap 17 pressed down. As a result, the bulk can be reduced and unnecessary ejection of bubbles can be prevented.

FIG. 4 shows a second embodiment of the present invention.
An example is shown in FIG. In FIG.
A bubble receiving tray 35 is attached to the upper part of the base by a column 38, and a finger handle 34 is provided on the piston shaft. In this embodiment, when discharging the foam, the piston shaft is pushed down by the finger handle 34 as shown in FIG.
Does not move up and down, the foam discharge operation is stabilized, and since there is no protrusion such as a push rod on the upper portion of the foam tray 35, it is easy to scoop up the foam A accumulated in the foam tray. Further, as described later, when excess foam remains in the foam receiving tray 35, the excess foam is automatically collected in the container body 30, so that waste of resources can be omitted and adverse effects on the environment can be avoided.

In FIG. 5, a handle 3 is attached to the container body 30.
1 is provided, but the pump-type foam generating mechanism mounted on the base cap 32 and the intermediate cap 39 is the same as that shown in FIG. 2, so the description of the structure and operation of the same parts will be omitted, The explanation of the different structures and functions will be focused on. A finger handle 34 extending in the lateral direction is provided on the outer periphery of the piston shaft 33 of the air piston, and a hollow sliding tube is integrally attached above the finger handle 34. On the other hand, a foam receiving tray 35 is attached to the upper part of the container body 30 with a base cap 32 via its support column 38, a nozzle 40 having a foam discharge port 41 is attached to a central hole of the foam receiving tray 35, and an air piston shaft is attached to the central hole. 33 hollow sliding tubes are fitted.

A recess 36 is formed in the center of the inner surface of the bubble receiving tray 35, an opening 39 is formed in the recess 36, and a return tube 37 is attached. It is connected to the upper part of the handle 31.

When the finger handle 34 is depressed, the piston shaft 33 is lowered, and the foam generated by the pump action is discharged from the foam discharge port 41 of the nozzle 40 to the foam receiving tray 35 through the hole of the hollow sliding tube. This operation is repeated to store a desired amount of foam in the foam tray 35. When there is excess foam in the foam receiving tray 35, the foam disappears and returns to liquid after a while. This liquid collects in the concave portion 36 of the bubble receiving tray 35 and is automatically collected in the container main body 30 through the return tube 37 from the opening 39.

[0020]

According to the present invention, since a desired amount of foam can be stored in the foam tray attached to the upper portion of the container body, the operation can be efficiently continued when the foam is used continuously. Also, when the remaining foam is left, the foam disappears and returns to liquid after a while,
Since this liquid can be automatically collected in the container body, waste of resources can be omitted and adverse effects on the environment can be avoided.
