And the inside of the container body 2 is maintained at the atmospheric pressure. Thereafter, the button portion 16 is raised by the restoring force of the spring 9, and one ejection operation is completed.

On the other hand, as a conventional foam discharge container, for example, there is one shown in FIG. This foam discharge container 30 has a cylindrical container body 32 made of a flexible synthetic resin or the like for containing liquid contents such as cosmetics.
And a bubble discharge mechanism 34 for sucking and discharging liquid contents as bubbles. In the foam discharge mechanism 34,

The narrow opening at the upper part of the container body 32 is fitted around the end of the cylindrical part 50, and a nozzle 52 is formed on the upper side wall of the cylindrical part 50. The discharge nozzle section 40 is constituted by the cylindrical section 50 and the nozzle 52.

A cylindrical portion 54 is provided integrally with the upper lid portion 42 at a distance from the liquid reservoir portion 38. The cylindrical portion 54 is provided with upper and lower valve seats 55a and 55b. A plurality of slits 56 are formed in the side wall of the cylindrical portion 54 near the lower valve seat 55b in the vertical direction in FIG. The ball 58 is loosely inserted into the hole. Next, the operation of the foam discharge container 30 having the above configuration will be described.

FIG. 5 shows a state in which the side wall of the container main body 32 is manually pushed in the direction of arrow x to pressurize the inside of the container main body 32 and discharge bubbles. At this time, as shown by an arrow b in FIG. The liquid content flowing into the tube 36 is a ball 48
To raise the gap between the ball 48 and the wide-diameter portion of the liquid reservoir 38. On the other hand, since the ball 58 closes the upper opening of the cylindrical portion 54 and the gas flow between the inside of the container body 32 and the cylindrical portion 50 is blocked, the pressurized gas ( The air (atmosphere) flows into the liquid reservoir 38 through the hole 44 of the liquid reservoir 38 as shown by an arrow c in FIG. The mixed fluid of the liquid content in the liquid reservoir 38 and the pressurized gas is:

[0012]

Among the conventional discharge containers described above, a liquid discharge container is easy to secure a desired discharge amount, but has a property of bubbles, for example, a liquid content. In the case of a cleaning agent, the feeling of use due to foaming cannot be immediately obtained, while the foam discharge container has a high use feeling due to foaming, but meets the high demands of consumers who cannot secure a desired discharge amount. There is a problem that can not be cut.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a liquid / bubble simultaneous discharge container capable of simultaneously discharging a liquid and a foam by a pressurizing operation.

This makes it possible to obtain a liquid / bubble simultaneous discharge container capable of simultaneously discharging the liquid and the foam by the pressurizing operation.

At this time, the liquid discharging mechanism has a first nozzle for discharging the liquid, and the bubble discharging mechanism has a mixing chamber for mixing the liquid and the gas, and a mixing chamber for mixing the liquid and the gas. And a second nozzle for discharging the foam generated by the above-described process. For example, it is easy to design a discharge container that arbitrarily changes the ratio of the amount of the liquid to the amount of the foam. -A foam simultaneous discharge container can be obtained.

In the liquid discharging mechanism and the bubble discharging mechanism, when one liquid discharging channel is branched and the liquid is supplied, a plurality of liquid content supply sources are prepared to discharge the liquid and the bubbles. It is not necessary, and it is preferable that the liquid and the foam can be simultaneously discharged by one liquid content supply source. Further, the pressurizing operation is performed by changing a volume of the liquid reservoir (liquid chamber) and the air reservoir in the container and dispensing a method of pressurizing the liquid chamber and the air reservoir, or by changing a volume of the container itself. The effect of the present invention can be suitably exerted by using any of the squeeze-type methods of pressurizing the inside of the container without using a pressure-resistant container. However, in the present invention, it does not preclude the use of a pressure-resistant container filled with a pressurized gas in order to obtain desired liquid and bubble discharge characteristics.

Further, the mechanism for discharging the foam further comprises:
By having a mesh between the mixing chamber and the second nozzle, fine and uniform foam can be suitably obtained. At this time, the mesh is preferably 1 or 2
Although the above-mentioned mesh-shaped wire mesh or the like can be used, the invention is not limited thereto, and any network in which a number of fine passages for dispersion are formed can be used. For example, a porous plate or the like can be used. .
