JP 2011-98777 A

By the way, in the conventional foaming container, even before the contents and air are mixed with the impregnated body, for example, the foaming container falls down unexpectedly, or the foaming container is inverted from the upright position. Or the like, the contents may unintentionally impregnate the impregnated body. When the contents and air are mixed with the impregnated body impregnated with the unintended contents in this way, there is a problem that the foam quality of the foam foamed by the impregnated body is difficult to stabilize.
In the conventional foaming container, as described above, the impregnated body impregnates the impregnated body when the foaming container is accidentally overturned or when the foaming container is changed from an upright position to an inverted position. In addition to this, the contents may be unintentionally leaked outside the foaming container.

  This invention is made | formed in view of the situation mentioned above, Comprising: While making it easy to stabilize foam quality, it aims at providing the foaming container which can suppress the leakage which the content does not intend.

In order to solve the above problems, the present invention proposes the following means.
The foaming container according to the present invention includes a squeeze-deformable container body that contains contents and air, and a communication hole that is disposed in the mouth of the container body and communicates with the container body. A cap and a cap that covers the inner plug from the outside of the container main body, is attached to the mouth of the container main body so as to be movable in the container axial direction, and opens and closes the communication hole in accordance with the movement in the container axial direction And an impregnated body to which the contents or air in the container main body that has circulated through the communication hole is supplied.

In the present invention, the communication hole is closed with the mounting cap before use. Thereby, for example, even when this foaming container falls down unexpectedly, or when this foaming container is changed from an upright position to an inverted position, before mixing the contents and air with the impregnated body, It is possible to prevent the contents from being impregnated into the impregnated body unintentionally or the contents from being unintentionally leaked out of the foaming container.
On the other hand, during use, the mounting cap is moved in the container axial direction to open the communication hole. For example, the foaming container is placed in an inverted position to allow the communication hole to flow through the contents in the container body. The product is fed to the impregnated body. Thereafter, for example, by squeezing the container main body in a state where the foaming container is in an upright posture, the communication holes are circulated through the air in the container main body, and the air is supplied to the impregnated body. The contents and air are mixed and foamed.

  As described above, according to this foaming container, since the mounting cap opens and closes the communication hole as the container moves in the axial direction, the contents are intended before the contents and air are mixed with the impregnated body. Without impregnating the impregnated body, the foam quality can be easily stabilized and unintentional leakage of the contents can be suppressed.

  The inner plug includes a communication tube portion extending in the container axial direction and the communication hole extending in the radial direction, and the mounting cap is slidably fitted in the communication tube portion in the container shaft direction. The outer peripheral surface may include an open / close cylinder part that opens and closes the communication hole from the inside in the radial direction, and the impregnated body may be accommodated in the open / close cylinder part.

  In this case, since the outer peripheral surface of the open / close cylinder portion opens and closes the communication hole from the inside in the radial direction, and the impregnated body is accommodated in the open / close cylinder portion, the sliding surface temporarily slides from the communication hole to the outer peripheral surface of the open / close cylinder portion. Even if the contents enter between the inner peripheral surface of the moving cylinder part, it is possible to make it difficult for the contents to reach the impregnated body, and it is ensured that the contents are unintentionally impregnated into the impregnated body. Can be suppressed.

  Further, in the opening / closing cylinder portion, the foaming container is opened in an upright position in a portion located outside the container main body with respect to the impregnated body, and the foaming container is set in an inverted posture. An on-off valve that is closed in a state may be provided.

In this case, when the communicating hole is circulated through the contents in the container body, if the foam container is in an inverted posture, the contents circulated through the communicating hole are supplied to the impregnated body with the on-off valve closed. The Thereby, it is suppressed that this content passes through the impregnated body and flows out from the open / close cylinder portion to the outside of the container main body.
Further, when the foaming container is brought into an upright posture when the communication hole is circulated through the air in the container main body, the air circulated through the communication hole is supplied to the impregnated body with the on-off valve being opened. As a result, after the air is supplied to the impregnated body, the foam foamed by the impregnated body is smoothly led out from the open / close cylinder portion to the outside of the container body.
As described above, the contents flowing through the communication hole are prevented from flowing out from the opening / closing cylinder part to the outside of the container body, and the foam foamed by the impregnated body is smoothly transferred from the opening / closing cylinder part to the outside of the container body. Since it can lead out, the operativity of this foaming container can be improved.

  Further, a restriction cylinder portion that extends from the mouth portion toward the inside of the container main body along the container axial direction and communicates the communication hole and the inside of the container main body may be provided.

  In this case, since the restriction cylinder part is provided, when the container body is squeezed and deformed, when the container body is abutted against the restriction cylinder part, further squeeze deformation of the container body can be restricted. Thereby, it becomes possible to stabilize the deformation amount of the container body, and it is possible to suppress the supply amount of air or the like supplied to the impregnated body through the communication hole from varying, and to easily stabilize the foam quality. .

  According to the foaming container according to the present invention, it is possible to easily stabilize the foam quality and to suppress unintentional leakage of the contents.
