A portion 79 is provided.

Next, usage modes and operational effects of this embodiment will be described.
In order to discharge the contents filled in the container in the form of foam, the body part 1 is gripped and squeezed to increase the internal pressure of the filling space M.
The contents are sucked up from the suction pipe 13 and rise, and pass through a gap between the ribs 38, which is limited by the ribs 38 protruding from the inner wall 30 disposed on the inner periphery of the cylinder body 10 and the rod body 23. To go.
At the same time, the air in the filling space M flows into the outer groove portion 37a of the inner wall 30 from the air inlet hole 35 of the cylinder bottom body 14 and the notch 36 at the lower end of the cylinder body 10, and passes through the upper groove portion 37b. The contents that have risen from the gap between them join together, and both pass through the gap between the connecting pieces 22.

The contents that have risen in the gas-liquid merge space G while being mixed with air are bubbled by passing through the mesh 73 disposed in the mixing flow path K of the cylindrical plug P, and further, the flexible cylindrical portion 72. The ink is discharged from the discharge flow path H in the nozzle 63 to the outside through the discharge port 64.
At this time, since the check valve 39 is strongly pressed against the lower end surface of the fitting wall 25 by the internal pressure of the filling space M, air does not leak from the through hole 20 and the slit groove 27 of the flange 15.

When the hand 1 is released from the body 1 of the container body A after discharging the foam-like contents, the body 1 deformed by the squeezing tends to return to the original shape, so that the internal pressure in the filling space M is negative. Become.
Therefore, the check valve 39 is opened, and the outside air flows into the filling space M from the through-hole 20 and the slit groove 27, and the negative pressure in the filling space M is eliminated, so that the body 1 is quickly returned to the original shape. Return.
In the present embodiment, the slit groove 27 penetrates the inside and outside of the upper cylinder 18, but the slit groove 27 may have a shape into which the detent rib 53 is fitted and does not necessarily have to penetrate.
If the slit groove 27 does not penetrate inside and outside, the outside air flows into the filling space M only from the through hole 20.

Thereafter, when the container is not used, the nozzle 63 is gripped and rotated in the direction of arrow Y in FIG.
The nozzle cap C2 rotates about the axial direction with respect to the cap body C1 because the sliding groove 61 is fitted to the sliding protrusion 52 of the cap body C1 so as not to be separable and rotatable.
At this time, the upper end connecting portion 71 of the cylindrical plug P is fitted into the upper connecting tube 58 of the nozzle cap C2, and the upper end protrusion 78 is fitted into the upper vertical groove 65. Rotates with C2.

On the other hand, in the lower end connecting portion 70 of the cylindrical plug P, the lower end groove 75 is fitted into the rotation-preventing rib 53 of the cap body C1, and the lower end protrusion 76 is fitted into the lower vertical groove 26 of the cylinder portion S. .
And since the slit groove 27 of the cylinder part S is also fitted in the rotation prevention rib 53, the lower end connection part 70 of the cylindrical plug P is attached and fixed to the cap main body C1 together with the cylinder part S so as not to rotate. ing.
Therefore, as the rotation angle of the nozzle cap C2 in the Y direction increases, the flexible cylindrical portion 72 is twisted and deformed as shown in FIG. A cut-off state is obtained in which the cross section of K is deformed and reduced.
In the non-use state in which the mixing channel K is blocked, the gas-liquid merge space G can be blocked from the outside air, and the inside of the foam discharge container can be protected from the outside air.

In the present embodiment, since the nozzle 63 protrudes from the outer cylinder 56 that forms the outer peripheral surface of the nozzle cap C2, even if the restoring force of the cylindrical plug P works due to the torsional deformation of the flexible cylinder portion 72. A large rotational operation force can be obtained by gripping and operating the nozzle 63 having a large rotation radius, and the nozzle cap C2 can be easily rotated.
In the present embodiment, the shape of the flexible cylindrical portion 72 such as the length and thickness is set so that the nozzle cap C2 can be brought into the non-use state by rotating about 180 °.
Furthermore, when this non-use state is reached, the stopper engaging portion 60 of the nozzle cap C2 is engaged with the stopper 51 of the cap body C1, and the non-use state can be maintained.

When the nozzle cap C2 is rotated from the use state to about 180 °, first, the small protrusion 60a of the stopper engaging portion 60 comes into contact with the stopper 51.
The protrusion height of the small protrusion 60a is set so as to be able to get over if the nozzle cap C2 is strongly rotated. Therefore, if the nozzle cap C2 is further rotated, the small protrusion 60a gets over the stopper 51 and becomes large. The protrusion 60 b comes into contact with the stopper 51.
The large protrusion 60b has a protruding height higher than that of the small protrusion 60a and cannot be overcome. Even if the operator removes his / her hand from the nozzle cap C2 and a restoring force is applied to the cylindrical plug P, the small protrusion 60a is stopped by the stopper 60a. The stopper 51 can be engaged by coming into contact with 51, and the non-use state can be maintained.
When the container is used again, if the small protrusion 60a gets over the stopper 51 by rotating the nozzle cap C2, the mixing channel K can be easily communicated with the restoring force of the cylindrical plug P itself to return to use. To do.

  As described above, the foam discharge container of this embodiment can rotate the nozzle cap C2 to the non-use state when not in use and shut off the gas-liquid merge space G from the outside air. Even if the container is firmly held or the container is tilted, the contents are not inadvertently leaked, and the use or non-use state of the container can be easily switched.

Next, a description will be given of a second embodiment in which the configuration of the mounting portion of the cylindrical plug is changed in accordance with the change in the configuration in which the check valve is integrally provided in the cylindrical plug.
Hereinafter, the difference from the first embodiment will be mainly described.

As shown in FIG. 10, in this embodiment, the check valve 139 is provided integrally with the lower end flange 81 of the cylindrical plug P, and the valve end is pressed against the lower surface of the upper wall 142.
The lower end flange 81 abuts on the upper surface of the flange 115 of the cylinder portion S, and a fitting groove 82 provided in the lower portion on the outer peripheral side extends radially inward from the fitting wall 125 and stands on the upper surface of the flange 115. The anti-rotation rib 153 is fitted.
Therefore, the lower end connection part 170 of the cylindrical plug P does not rotate with respect to the cap body C1 together with the cylinder part S that is non-rotatably attached to the cap body C1 by means not shown.

Thus, in this embodiment, since the check valve 139 is provided integrally with the cylindrical plug P, the structure is simplified and assembly is facilitated.
Further, since the check valve 139 and the rotation prevention rib 153 are accommodated between the flange 115 and the upper wall 142, the foam discharger B is compact, and the entire container can be compact.
Other functions and effects are the same as in the first embodiment.

  The foam discharge container of the present invention can be used in a simple structure, can be switched between use and non-use state to block the internal flow path from the outside air, and can be used hygienically and stably, so shampoo and body soap It can be suitably used as an inexpensive container containing various liquid detergents such as styling and hairdressing materials.
