  However, in the conventional foam ejection container, when the foam ejection container is inverted, the content liquid moves to the mouth side of the container main body and the air in the head space moves to the bottom side of the container main body, and the content liquid passes through the air passage. The air can be supplied to the gas-liquid mixing chamber through the air passage and the air can be supplied to the gas-liquid mixing chamber through the liquid passage. For this reason, it is possible to eject the content liquid even when the foam ejection container is in an inverted posture. However, for example, the content liquid is ejected in a state different from the desired foam quality or is different from the desired position. There was a risk of being ejected to the position.

  Then, an object of this invention is to provide the foam ejection container which suppressed that a content liquid was ejected, for example, when a foam ejection container was made into an inverted posture.

  The present invention employs the following means in order to solve the above problems. That is, the foam ejection container of the present invention is mounted on an elastically deformable container main body in which the content liquid is accommodated, and the mouth of the container main body, and the content liquid is mixed with air and ejected in a foam shape. A foam jet cap formed with an ejection hole to be supplied, and the foam jet cap supplies a gas-liquid mixing chamber communicating with the jet hole and a liquid content in the container body to the gas-liquid mixing chamber. A liquid passage and an air passage for supplying air in the container body to the gas-liquid mixing chamber, and the bubble ejection cap passes through the liquid passage when the container body is inverted, A liquid valve member for blocking communication with the gas-liquid mixing chamber, and an air valve member for blocking communication between the inside of the container body and the gas-liquid mixing chamber through the air passage when the container body is inverted. The container body or the foam ejection cap has a front An outside air introduction hole for introducing outside air into the container body is formed, and the container body or the bubble ejection cap prevents the flow of air and content liquid from the inside of the container body to the outside through the outside air introduction hole. An air check valve is provided that allows air to flow from the outside through the outside air introduction hole into the container body.

In the present invention, in the state where the bubble ejection container is in an upright posture, for example, communication between the inside of the container body through the air passage and the gas-liquid mixing chamber is allowed, and the inside of the container body through the liquid passage and the gas-liquid mixing chamber Therefore, when the container body is compressed and deformed (squeezed) toward the inside in the radial direction, the internal pressure of the container body is increased, and the air in the container body passes through the air passage into the gas-liquid mixing chamber. While flowing in, the content liquid in the container body flows into the gas-liquid mixing chamber through the liquid passage, and the content liquid can be ejected from the ejection hole with the foam quality (for example, the mixing ratio of air and the content liquid) as set. . In the above process, the air check valve prevents communication between the outside of the bubble ejection container and the inside of the container body through the outside air introduction hole. And, for example, when the bubble ejection container is in an inverted posture, the communication between the container body through the air passage and the gas-liquid mixing chamber is blocked and the communication between the container body through the liquid passage and the gas-liquid mixing chamber is performed. Therefore, even if the container body is compressed and deformed, the content liquid is not ejected from the ejection holes. Therefore, in the state which made the bubble ejection container the inverted posture, for example, it can suppress that a content liquid is ejected.
In addition, since the ejection of the content liquid is suppressed when the foam ejection container is in an inverted position, for example, the user is encouraged to eject the content liquid in a state where the foam ejection container is in a predetermined attitude, such as an upright position. Make it.

Moreover, in the foam ejection container of the present invention, at least one of the liquid valve member and the air valve member includes a valve cylinder that communicates between the gas-liquid mixing chamber and the container body, and the valve cylinder. A ball valve movably disposed in the body, and the valve body seats the ball valve and communicates the inside of the container body through the valve body and the gas-liquid mixing chamber. A valve seat that can be shut off may be provided.
In this invention, by setting the bubble ejection container in an inverted posture, for example, the communication between the container body through the air passage and the gas-liquid mixing chamber and the gas-liquid mixing through the liquid passage by the dead weight of the ball valve. Since at least one of the communication with the chamber is blocked, the operability of the foam ejection container can be improved.

  According to the foam ejection container according to the present invention, in the state in which the foam ejection container is in an inverted position, for example, the communication between the container body through the air passage and the gas-liquid mixing chamber and the inside of the container body through the liquid passage and the gas liquid. Since the communication with the mixing chamber is blocked, it is possible to suppress the content liquid from being ejected from the ejection holes.

Next, the usage method of the foam ejection container 1 of the above structures is demonstrated.
First, in the upright posture shown in FIGS. 1 to 3, the first ball valve 48 allows communication between the inside of the container body 2 and the gas-liquid mixing chamber 35 through the air passage R1, and the second ball valve 63 is The communication between the inside of the container body 2 and the gas-liquid mixing chamber 35 through the liquid passage R2 is allowed. In this state, the body 5 of the container body 2 is compressed and deformed, and the pressure in the container body 2 is increased. Here, since the air check valve 15 is closed, the air in the head space in the container body 2 does not leak outside through the outside air introduction hole 28B.

Thereby, the air in the head space in the container main body 2 enters the air passage R1 through the air introduction hole 46A, and flows into the gas-liquid mixing chamber 35 through the air passage R1. Further, the content liquid in the container body 2 enters the liquid passage R2 through the liquid introduction hole 61A, and flows into the gas-liquid mixing chamber 35 through the liquid passage R2.
The air and the content liquid that have flowed into the gas-liquid mixing chamber 35 are mixed in the gas-liquid mixing chamber 35, pass through the foaming member 13, and are foamed and regulated. Then, the foamed and foamed content liquid flows into the nozzle cylinder portion 27 through the communication hole 28A, and is ejected from the ejection hole 4A in a bubble shape.

  When the compressive deformation of the body part 5 is released after the content liquid is ejected, the body part 5 starts to be deformed and a negative pressure is generated in the container body 2. Thereby, the radial direction outer end of the seal part 52 of the air check valve 15 is separated from the lower surface of the second annular connection part 24 by the negative pressure, and the air check valve 15 is opened. Thereby, the ejection hole 4A and the inside of the container body 2 are communicated with each other through the outside air introduction hole 28B. Then, the air outside the foam ejection container 1 is introduced into the container body 2 through the nozzle cylinder 27 and the outside air introduction hole 28B. The content liquid remaining in the nozzle cylinder portion 27 is also drawn into the proximal end portion side of the nozzle cylinder portion 27. By such a suck back function, the content liquid remaining in the nozzle cylinder portion 27 after the ejection is suppressed from dripping from the ejection hole 4A.

When the outside air is sufficiently introduced into the container body 2, the air check valve 15 is closed by releasing the negative pressure in the container body 2.
Thereafter, when the content liquid is ejected again, the body portion 5 of the container main body 2 is compressed and deformed again as described above.

Next, as shown in FIG. 4, for example, when the bubble ejection container 1 is turned upside down (which may be vertical or tilted), the air in the head space in the container body 2 flows into the body of the container body 2. The liquid in the container body 2 moves to the bottom side of the part 5 and moves to the mouth 3 side in the container body 2. The air introduction hole 46A is located below the liquid level of the content liquid, and the liquid introduction hole 61A is located above the liquid level.
Further, the first ball valve 48 falls due to its own weight and is seated on the first valve seat portion 49 as indicated by a virtual line in FIG. Thereby, the communication between the inside of the container main body 2 and the gas-liquid mixing chamber 35 through the air passage R1 is blocked. Similarly, the second ball valve 63 falls due to its own weight and is seated on the second valve seat portion 64, as indicated by a virtual line in FIG. Thereby, the communication between the inside of the container body 2 and the gas-liquid mixing chamber 35 through the liquid passage R2 is blocked.

In this state, even if the body 5 of the container body 2 is compressed and deformed, the air check valve 15 is closed, and the container body 2 through the air passage R1 and the gas-liquid mixing chamber 35 are closed. Since the communication between the container body 2 and the gas-liquid mixing chamber 35 through the liquid passage R2 is blocked while the communication is blocked, the content liquid in the container body 2 is prevented from being ejected from the ejection holes 4A. Is done.
For example, when the viscosity of the content liquid is high, the first and second ball valves 48 and 63 are arranged so that the first and second valve seat portions are compressed when the body portion 5 of the container body 2 in the inverted posture is compressed and deformed. 49 and 64 are separately seated and the communication between the container body 2 and the gas-liquid mixing chamber 35 through the air passage R1 and the communication between the container body 2 and the gas-liquid mixing chamber 35 through the liquid passage R2 are blocked. May be.

As described above, since the content liquid in the container body 2 is suppressed from being ejected in the inverted posture, the user is encouraged to eject the content liquid in the state where the bubble ejection container 1 is in the upright posture. It is.
As described above, the foam ejection container 1 is used.

As described above, according to the foam ejection container 1 according to the present embodiment, when the foam ejection container 1 is in the inverted posture, the communication between the inside of the container body 2 through the air passage R1 and the gas-liquid mixing chamber 35 and the liquid passage R2 are performed. Since the communication between the container body 2 and the gas-liquid mixing chamber 35 is blocked, it is possible to suppress the content liquid from being ejected from the ejection holes 4A. For this reason, the user can be urged to eject the content liquid in a state in which the bubble ejection container 1 is in a predetermined posture, for example, an upright posture.
Further, by setting the bubble ejection container 1 in an inverted posture, the communication between the container body 2 and the gas-liquid mixing chamber 35 through the air passage R1 and the liquid passage R2 through the air passage R1 due to the weight of the first and second ball valves 48 and 63 is established. Since the communication between the inside of the container main body 2 and the gas-liquid mixing chamber 35 can be blocked, the operability of the foam ejection container 1 is improved.

Furthermore, the inner diameter and outer diameter of the lower end portion of the second valve cylinder 105 are gradually reduced toward the lower side. Accordingly, the second ball valve 63 once accommodated in the second valve cylinder 105 is prevented from being detached from the second valve cylinder 105.

The usage method of the foam ejection container 100 of such a structure is the same as that of the foam ejection container 1 concerning 1st Embodiment mentioned above.
In addition, the bubble ejection container 100 having such a configuration also provides the same operations and effects as the above-described embodiment.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the outside air introduction hole is formed in the foam ejection cap, but may be formed in the container body. Moreover, although the outside air introduction hole communicates with the ejection hole, it does not need to communicate with the ejection hole.
The air check valve is provided in the foam ejection cap, but may be provided in the container body.
The configurations of the liquid valve member and the air valve member may be appropriately combined with the configurations described in the first and second embodiments, or may be different configurations.
The first valve cylinder of the air valve member extends along the container axis, but may be inclined with respect to the container axis. Similarly, the second valve cylinder of the liquid valve member is inclined with respect to the container axis, but may extend along the container axis.
The liquid valve member and the air valve member may be configured using a valve other than the ball valve.
For example, in the description of the shape of each component such as the first valve cylinder, it is described as “cylindrical”, but other shapes such as a polygonal cylinder or an elliptic cylinder may be used as appropriate.

  According to this invention, industrial applicability is recognized regarding the foam ejection container which suppressed that the content liquid was ejected when the foam ejection container was set to the inverted posture.
