In this type of foam discharge container, it is required to simplify the shape of the container body from the viewpoint of the manufacturing cost of the container body and the like.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a foam discharge container capable of simplifying the shape of the container body.

In order to solve the above problems, the foam discharge container of the present invention has a body that is elastically deformable and contains the contents, and a cap body that is attached to the mouth of the container body. The cap body has a top wall in which a discharge hole is formed and a bottomed tubular communication cylinder extending downward from the top wall, and the peripheral wall of the communication cylinder has the above. An introduction hole for communicating the inside of the container body and the discharge hole is formed, and the bottom wall of the communication cylinder gradually extends downward from one side in the radial direction toward the other side, and the introduction hole is the communication. It is characterized in that it is formed at least at the end of the other side of the peripheral wall of the cylinder in the radial direction, and the discharge hole is located on the one side in the radial direction with respect to the introduction hole.

According to the foam discharge container of the present invention, a discharge hole is formed in the top wall of the cap body, and an introduction hole is formed in the peripheral wall of a bottomed tubular communication cylinder extending downward from the top wall. .. With this configuration, when the foam discharge container is tilted so that the introduction hole is at a high position in the vertical direction and the body of the container body is elastically deformed to reduce the internal volume of the container body, the foamed contents pass through the introduction hole. It is introduced into the communication cylinder and discharged from the discharge hole. At this time, since the unfoamed contents are accumulated at a low position in the vertical direction due to their own weight, the inflow from the introduction hole into the communication cylinder is suppressed. In this way, the communication cylinder can keep the unfoamed contents in the container body while introducing the foamed contents into the discharge holes.
Further, since the communication cylinder that exerts the above-mentioned action and effect is provided in the cap body, the shape of the container body can be simplified.

Here, the bottom wall of the communication cylinder gradually extends downward from one side in the radial direction toward the other side, and the introduction hole is formed in the peripheral wall of the communication cylinder at least on the other side in the radial direction. It is formed at the end.

In this case, if the foam discharge container is tilted so that the position of the introduction hole in the vertical direction becomes higher, the position of the other end of the bottom wall in the vertical direction becomes higher. Therefore, when the foam discharge container is tilted as described above, it becomes difficult for the unfoamed contents to get over the bottom wall, and it is possible to more reliably suppress the contents from flowing into the communication cylinder from the introduction hole. Can be done.

Further, the discharge hole is located on one side of the introduction hole in the radial direction .

In this case, if the foam discharge container is tilted so that the discharge hole is lowered in the vertical direction, the position of the introduction hole in the vertical direction is naturally raised, so that the operability of the foam discharge container can be improved.

Further, the bottom wall and the peripheral wall of the communication cylinder may be connected to each other by a hinge.

In this case, the cap body having a bottomed tubular communication cylinder extending downward from the top wall can be easily formed by injection molding or the like, and the manufacturing cost of the foam discharge container can be further reduced. ..

Further, the container body may be formed with a recess that is recessed inward in the radial direction, and the recess and the introduction hole may be arranged at the same positions in the vertical direction.

In this case, since the recess and the introduction hole are arranged at the same positions in the vertical direction, the gap between the portion of the peripheral wall of the communication cylinder where the introduction hole is formed and the container body becomes small, and the contact is not foamed. It is suppressed that the contents of the above flow toward the introduction hole through this gap.

Further, on the bottom wall of the communication cylinder, a protruding portion is formed which protrudes outward in the radial direction from the portion of the peripheral wall of the communicating cylinder in which the introduction hole is formed, and the recess and the protruding portion move up and down. They may be arranged at equivalent positions in the direction.

In this case, when the foam discharge container is tilted as described above, the protrusion is located at a higher position in the vertical direction, and the gap between the protrusion and the container body is reduced by the recess. As a result, the unfoamed contents are more reliably suppressed from flowing toward the introduction hole by overcoming the protrusion or passing through the gap between the protrusion and the container body.

According to the present invention, it is possible to provide a foam discharge container in which the shape of the container body is simplified.
