Description

  The present invention relates to a foam ejection container that foams and ejects a fluid content (liquid, gel, etc.) by repeating deformation and restoration by squeezing the body of the container.

  The so-called squeeze-type foam ejection container is a foam generating member typified by a mesh member inside the ejector for the purpose of miniaturization in consideration of portability while omitting the foaming operation for easy use. In addition, the body portion of the container body filled with the contents can be deformed and restored, so that the mixture of the contents and air is foamed through the foam generating member by the compression (deformation) of the body portion. It is made to discharge as foamy contents.

In order to prevent unintentional foam ejection during distribution, these conventional foam ejection containers open and close the ejection holes by allowing the opening / closing member attached to the mouth of the container body to rotate clockwise and counterclockwise. (For example, see Patent Document 1)
Japanese Examined Patent Publication No. 3-66938

  However, the conventional foam ejection container has a structure that opens and closes the ejection passage at a position downstream of the foam generation member (on the ejection nozzle side) by rotating the opening and closing member. There was a risk of remaining in the ejection passage and affecting the ejection state during use.

  That is, when the foam-like contents remain in the ejection passage, there is a concern that fine bubbles cannot be generated when used again.

The problem to be solved by the present invention is to prevent unintentional foam ejection at the time of distribution and the like and to maintain good foam ejection performance,
A new foam ejection container that eliminates the conventional problems by preventing the contents from flowing out of the container body into the nozzle or the inner container due to unexpected external force or the like, or by overturning the container. It is to provide.

  The foam ejection container according to the present invention has a body portion that can be deformed and restored by a squeeze operation, and forms a filling space for contents inside the body portion, and the filling space of the container body An inner container that has a barrel part that can be deformed and restored following the squeeze operation by hanging down, and that forms an air-filling space inside the trunk part, and is disposed above the mouth part of the inner container. A pipe body that introduces air into the filling space of the vessel, and a peripheral wall that surrounds the pipe body, and an annular passage formed between the peripheral wall and the pipe body contains air from the inner container and contents from the container body. A nozzle having a foam generating member that passes through and is discharged as a foam-like content, and allows the nozzle to rotate clockwise and / or counterclockwise around the tube body, and at the bottom of the nozzle A holding part for holding the foam generating member A nozzle bottom member formed with an opening that allows introduction of contents is provided, and the nozzle bottom member opens and closes communication between the inside of the container body and the inside of the nozzle by rotating the nozzle clockwise and / or counterclockwise. An opening / closing part is formed.

  Moreover, according to this invention, the protection cylinder body which hangs down in the filling space of a container main body and surrounds an inner container can be integrally formed in the said pipe body. In this case, it is preferable to form a window hole for allowing the contents to pass through the protective cylinder.

  Further, according to the present invention, a check valve that seals the tubular body when the contents are ejected along with the deformation of the container body and opens the tubular body when the inner container is restored along with the restoration of the container body. It is preferable to provide.

  Examples of the foam generating member according to the present invention include porous bodies such as a sintered body and a foam, and an annular mesh ring in which a mesh is disposed between an inner ring and an outer ring. It is not limited to this as long as it is a member having a structure capable of transmitting the contents (liquid, gel, etc.) and gas (air).

  According to the foam ejection container of the present invention, between the pipe body for introducing air into the inner container and the nozzle having a peripheral wall surrounding the pipe body and forming an annular passage between the peripheral wall and the pipe body. A foam generating member for allowing air from the tube and the contents from the container body to pass through and discharging as a foam-like content, while this nozzle is rotated clockwise and / or counterclockwise around the tube The nozzle bottom member is provided with a holding portion that holds the foam generating member at the bottom of the nozzle and has an opening that allows the contents to be introduced. Since the material is provided with an opening / closing part that opens and closes the communication between the container body and the inside of the nozzle by rotating the nozzle clockwise and / or counterclockwise, the nozzle is rotated clockwise and / or counterclockwise around the tube body. Just inside the nozzle and inside the container body The communication from the container is opened and closed, so even if an unexpected external force is applied during distribution or the container is in a fallen state, the contents from the container body must be guided to the foam generating member arranged in the nozzle. There is no. Moreover, according to this structure, the contents do not enter the inner container.

  Therefore, according to the present invention, it is possible to prevent unexpected liquid leakage and intrusion of contents into the inner container.

  In addition, according to the present invention, since it is not a structure for blocking the ejection of the content that has been foamed through the foam generating member as in the prior art, the content can enter the ejection passage during distribution. Is prevented. For this reason, according to this invention, a favorable foaming state can be maintained.

  That is, according to the present invention, fine bubbles can be stably generated without concern that fine bubbles cannot be generated during use due to the influence of the contents that have entered the ejection passage during distribution.

  Further, in the present invention, if the tube is integrally formed with a protective cylinder that hangs down in the filling space of the container body and surrounds the inner container, the inner container at the time of filling the contents, at the time of refilling, at the time of replacement, etc. Is prevented from being damaged. As a result, the inner container can be made thinner, which is advantageous for reducing the materials used and for making the inner container compact.

  In addition, the protective cylinder functions as a stopper when the body portion of the container body is deformed. That is, when the body part of the container body is pushed in, the body part comes into contact with the protective cylinder so that it cannot be pushed any further, so quantitative ejection of contents and stable deformation and restoration are possible. It becomes.

  Further, if a window hole for allowing the contents to pass through is formed in the protective cylinder, the contents can be efficiently guided.

  Furthermore, in the present invention, the tube body is provided with a check valve that seals the tube body when the contents are ejected along with the deformation of the container body and opens the tube body when the inner container is restored along with the restoration of the container body. Then, when the contents are ejected, the inside of the tube is surely cut off, so that the mixing ratio of the contents and air becomes constant, and stable quality bubbles can be obtained.
