Both of the free opening ends are located in the liquid in the container, and there is no other choice but to discharge the content liquid from the nozzle in a liquid state.

[0005]

However, the prior art has the following problems. When a soft dip tube is used, the free open end of the long dip tube is pushed into the container and bent into a curved shape while the free open end of the long dip tube is abutted against the container bottom, and the free open end of the tube is brought close to the container bottom corner. Will be set to In this case, it becomes difficult to set the free opening end of the dip tube on the side opposite to the discharge direction of the nozzle with the substantially center line of the container body interposed, and the assembling workability of the container is poor.

[0006] When a hard dip tube is used, a dip tube that has been previously formed by bending is used. In this case, the insertion direction of the tube into the easy main body becomes curved, and the assembling workability of the container is poor.

[0007] The above impedes the productivity of the container, such as making it difficult to automate the insertion of the tube into the container body.

The present invention provides a foamed container which can generate foam even in a use state where the container is substantially horizontal.
An object of the present invention is to improve the workability of assembling a container.

In the foaming container 10, a nozzle 15 which can be opened and closed is screwed to the discharge side of the gas-liquid mixing joint 13 of the cap 12 (outside the screen 13B). Nozzle 1
The nozzle 5 is rotated, for example, 90 degrees with respect to the cap 12, and is switched between the closed position and the open position.
The fifth sheet portion 16 is brought into close contact with the plug portion 17 of the cap 12, and in the open position, the sheet portion 16 is separated from the plug portion 17 so that a discharge path can be formed. In addition, the discharge port 18 of the nozzle 15 forms a fixed inclination angle with respect to the center axis of the cap 12, and determines the discharge direction at the above-described open position.

The foam container 10 has a ball-shaped air return valve 22 in the air return path 21 of the cap 12. The air return valve 22 is connected to the air return path 21 when discharging bubbles.
The pressure inside the container squeezed in close contact with the upper sheet portion 21A is increased. The air return valve 22 is stopped by the lower protruding portion 21B of the air return path 21 after the end of the bubble discharge, and introduces external air into the container by negative pressure in the container based on the container restoring force after squeezing.

Is discharged from the discharge port 18 of the nozzle 15 via the above-described bubble discharge path.

At this time, the air return valve 22 is connected to the air return path 2
The pressure in the container is increased in close contact with the first sheet portion 21A.

After the liquid is discharged, the air return valve 22 is locked to the protrusion 21B of the air return path 21, and the external air is released by the negative pressure in the container based on the container restoring force after squeezing.
It is introduced into the container from the air return path indicated by arrow B in (C). At this time, the external air tends to pass through the reverse path of the above-described bubble discharge path (A). However, since the residual bubbles in the bubble discharge path (A) cause resistance, the external air returns to the above-described air return path (B). Take the route.

However, in the foam container 10, the center axis of the cap 12 is aligned with the center line of the container body 11 (the opening 11A).
The opening 11A is provided so as to be inclined by an angle θ with respect to the line connecting the center of the container body 11 and the center of the bottom of the container body 11, and the tube connecting portion of the gas-liquid mixing joint 13 provided on the central axis of the cap 12. 13A (tube support of the present invention)
