Utility Model Registration No. 3078012

However, since the conventional opening / closing mechanism for the spout provided in the spout container is a complicated valve body mechanism that uses the biasing force of the spring member, it takes time to manufacture and has room for improvement.
Further, each time the contents in the dispensing container are poured out, it is necessary to tilt the dispensing container while performing an opening / closing operation of pressing a button, and there is room for improvement in operability.

  This invention is made | formed in view of the situation mentioned above, Comprising: The objective is to provide the extraction container which can improve operability while being easy to manufacture.

In order to solve the above problems, the present invention proposes the following means.
The dispensing container according to the present invention includes an inner container that contains the contents and has flexibility, and an elastically deformable outer container in which an intake hole for sucking outside air is formed between the inner container and the inner container. A double container having a movable member that is mounted at the mouth of the double container and has a communication opening that communicates with the inside of the inner container and that can move up and down, and the contents can be poured out through the communication opening An extraction cap, an overcap that is detachably attached to the extraction body and covers the movable member, and an air valve that switches between communication between the outside and the intake hole and blocking of the intake port. The communication opening is formed, and a top wall portion is provided on the upper surface with a film covering the communication opening, and the film surrounds the communication opening and has a fixing portion at least partially opened in the circumferential direction. The heaven The communication opening is sealed by being fixed to the upper surface of the portion, and the inner portion of the fixing portion of the film is detachably in contact with the upper surface of the top wall portion, and the overcap includes the movable member An engaging portion is provided for moving the movable member up and down as the overcap is attached and detached, and the extraction body includes the communication opening and the inner container as the movable member moves up and down. A pour-out valve that switches between communication with the inside and switching off the connection is provided.

  In this invention, in the state before use in which the overcap is mounted on the pouring body, communication between the inside of the inner container and the communication opening is blocked by the pouring valve, and the film covering the communication opening is the top wall portion. The communication opening is sealed with a film by being in close contact with the upper surface of the inner container, and the hermeticity of the inner container is ensured.

Moreover, when using this pouring container, first, the overcap is detached from the pouring body. Then, the engaging part lifts and moves the movable member in accordance with the detachment operation, so that the disconnection of the communication between the inside of the inner container and the communication opening by the dispensing valve is released.
Thereafter, for example, the double container is tilted with the opening portion of the fixing portion facing downward to bring the pouring container into the pouring posture, or the double container is pressed toward the inner side in the radial direction to reduce the internal pressure of the inner container. The contents in the inner container are caused to flow out of the communication opening. Then, the film is pressed by the contents flowing out from the communication opening, and the inner portion of the fixed portion of the film swells away from the upper surface of the top wall portion into a dome shape protruding upward. Thus, a flow path communicating with the communication opening is formed between the film and the upper surface of the top wall portion, and a spout opening toward the outside is formed at the opening portion of the fixing portion. As a result, the content flowing out from the communication opening is poured out from the spout through the flow path.

Then, the outflow of the contents from the communication opening is stopped by returning the double container to the original upright posture or stopping and releasing the pressing of the double container. Then, the pressing force by the contents applied to the film is released, and the film separated from the top surface of the top wall portion is restored to the original state and is brought into close contact with the top surface of the top wall portion. As a result, the spout is closed and the communication opening is sealed by the film, so that the inner container is sealed again.
Then, after the use of the dispensing container is finished, the overcap is attached to the dispensing body. Then, the engagement portion moves the movable member downward in accordance with the mounting operation, so that the communication between the inside of the inner container and the communication opening is blocked by the dispensing valve.

As described above, since the spout can be opened and closed with a simple configuration in which the film is fixed to the upper surface of the top wall portion of the spout, the spout container can be easily manufactured.
Also, the contents are discharged from the communication opening and the film is pressed by the contents to open the spout and the contents are poured out, and by stopping the outflow of the contents from the communication opening. Since the outlet is closed and the communication opening is sealed, the operation of pouring the contents can be easily performed. That is, it is only necessary to perform the operation of causing the contents to flow out of the communication opening, and it is not necessary to separately perform the operation of opening and closing the spout, and the operability can be improved.

In addition, the communication between the inside of the inner container and the communication opening is blocked by the pouring valve, and the communication opening is sealed by the film, so that the inner container is sealed. It is possible to prevent the contents from being inadvertently poured out from the spout during distribution or storage.
In addition, the communication between the inside of the inner container and the communication opening by the pouring valve can be switched according to the operation of attaching and detaching the overcap, so that the operability of the pouring operation is suppressed while suppressing leakage of the contents. Can be made good.

  Further, the outside air inflow passage that communicates the outside and the intake hole is provided with a housing chamber that houses the air valve and has a valve seat opening that communicates with the outside. When the container is in an upright posture, it moves away from the valve seat opening and moves by its own weight in the accommodating chamber when the pouring container is in the pouring posture with the opening portion of the fixing portion facing downward. Then, the valve seat opening may be closed.

In this case, when the contents are poured out from the pouring container, the pouring container is brought into the pouring posture so that the air valve moves due to its own weight in the accommodating chamber and closes the valve seat opening. Therefore, even when an intermediate space is formed between the outer container and the inner container, when the double container is pressed toward the inner side in the radial direction, the inner pressure of the intermediate space is increased to the inner container. Acts and the internal pressure of the inner container rises reliably.
Also, after the contents are poured out from the dispensing container, when the double container is released with the hermeticity of the inner container secured, the outer container tries to be restored and deformed while the inner container is reduced in volume. . At this time, the negative pressure generated between the inner container and the outer container acts on the air valve through the intake hole, so that the air valve is separated from the valve seat opening, and the outside and the intake hole communicate with each other through the outside air inflow passage. Is done. Then, outside air flows into the outside air inflow path from the outside, and this outside air is sucked between the inner container and the outer container through the intake hole.

  Here, when the dispensing container is in the upright posture, the air valve is separated from the valve seat opening, so that the double container is formed with the intermediate space formed between the inner container and the outer container. Even if the outer container is inadvertently pushed inward in the radial direction by gripping the air, the air in the intermediate space is released to the outside through the intake hole and the outside air inflow passage. As a result, it is possible to suppress an increase in the internal pressure of the intermediate space, to suppress an increase in the internal pressure of the inner container, and to reliably prevent the contents from being inadvertently poured out from the spout.

  Moreover, the said extraction | pouring body may be equipped with the accommodation cylinder member by which the inside was made into the said accommodation chamber, and the said movable member may be connected with the said accommodation cylinder member via the connection hinge part.

  In this case, since the movable member is coupled to the housing cylinder member via the coupling hinge portion, the above-described effects can be reliably achieved while suppressing an increase in the number of parts.

  Further, the valve seat opening may be opened toward a direction in which the fixing portion is opened in the radial direction.

  In this case, since the valve seat opening is opened in the radial direction toward the direction in which the fixing portion is opened, when the pouring container is brought into the pouring posture, the valve seat opening is surely secured by the air valve. Can be occluded. That is, when the pouring container is in the pouring posture, the opening portion of the fixing portion is directed downward, and the pouring container is inclined toward the direction in which the fixing portion is opened in the radial direction. The air valve moves smoothly toward the valve seat opening by its own weight in the accommodation chamber.

  The dispensing container according to the present invention is easy to manufacture and can improve operability.

As shown in FIG. 3, the overcap 7 is attached to the extraction body 5 so as to cover the movable member 12, and the overcap 7 is provided with an engaging portion 29 that engages with the movable member 12. ing. A pair of engaging portions 29 are disposed so as to sandwich the top wall portion 11 in the left-right direction. The engaging portions 29 include a main body plate 30 extending downward from the overcap 7, and an engaging protrusion 31 protruding from the main body plate 30 and detachably engaged with the movable member 12 from below. It is equipped with.
In the illustrated example, the engagement protrusion 31 is engaged with the side end portion of the top wall portion 11 from below. As shown in FIG. 2, the front and back surfaces of the main body plate 30 extend in the front-rear direction, and the front end edge of the main body plate 30 is connected to the inner peripheral surface of the overcap 7.

Next, the effect | action of the extraction container 1 comprised as mentioned above is demonstrated.
First, in a state before use in which the overcap 7 is attached to the pouring body 5, the pouring valve 24 blocks the communication between the inside of the inner container 2 and the communication opening 52 and covers the communication opening 52. 13 is brought into close contact with the upper surface of the top wall 11, and the communication opening 52 is sealed by the film 13, and the hermeticity of the inner container 2 is ensured.

When using the pouring container 1, first, the overcap 7 is rotated around the hinge portion 6 to be detached from the pouring body 5. Then, as shown in FIG. 4, the engaging portion 29 moves upward while the engaging projection 31 engages with the side end portion of the top wall portion 11 of the movable member 12 from the lower side in accordance with the detachment operation. The engaging portion 29 moves the movable member 12 upward around the connecting hinge portion 25 to move upward. Thereby, the pouring valve 24 is separated upward from the upright cylinder portion 20 of the mounting member 10, and the blocking of the communication between the inside of the inner container 2 and the communication opening 52 by the pouring valve 24 is released.
When the movable member 12 moves up as described above, the communicating tube portion 23 and the standing tube portion 20 are in sliding contact with each other, and the standing tube portion 20 guides the ascending movement of the movable member 12, thereby moving the movable member 12. 12 will move up stably.

  In the illustrated example, as the movable member 12 moves upward, the movable member 12 rotates around the connecting hinge portion 25 so that the inner peripheral surface of the communicating cylindrical portion 23 and the outer peripheral surface of the standing cylindrical portion 20 are in close contact with each other. Thus, the upward movement of the movable member 12 is restricted. At this time, the engagement protrusion 31 of the engagement portion 29 climbs over the side end portion of the top wall portion 11 of the movable member 12 from below to above, and the engagement between the movable member 12 and the engagement portion 29 is released. . In addition, for example, the communicating cylinder part 23 and the standing cylinder part 20 may be provided with a regulating means (not shown) that regulates the upward movement of the movable member 12 by engaging each other.

  After detaching the overcap 7 in this manner, for example, the double container 4 is tilted forward with the spout 27 facing downward to bring the pouring container 1 into the pouring posture, and the double container 4 is set in the radial direction. To increase the internal pressure of the inner container 2. Then, after the contents in the inner container 2 circulates through the connection path 50, the film 13 is pressed by the contents flowing out from the communication opening 52 and flowing out from the communication opening 52, and the non-adhered portion 28 of the film 13 is It swells away from the top surface of the top wall 11 and forms a dome shape that protrudes upward (see the two-dot chain line shown in FIG. 4). Thereby, the flow path 32 communicating with the communication opening 52 is formed between the film 13 and the upper surface of the top wall portion 11, and the spout opening opened to the outside in the opening portion 26 a of the fixing portion 26. 27 is formed. As a result, the content flowing out from the communication opening 52 is poured out from the spout 27 through the flow path 32.

  Here, in the present embodiment, when the contents are poured out from the pouring container 1 with the pouring container 1 in the pouring posture as described above, the air valve 14 is moved by its own weight in the housing chamber 43 to The seat opening 46 is closed (see the two-dot chain line shown in FIG. 4). Therefore, even if the intermediate space 33 (see FIG. 5) is formed between the outer container 3 and the inner container 2, the double container 4 of the pouring container 1 in the pouring posture is disposed radially inward. When the pressure is applied toward the inner space 33, the internal pressure of the intermediate space 33 increases and acts on the inner container 2, and the internal pressure of the inner container 2 is reliably increased. At this time, since the internal pressure of the intermediate space 33 acts on the air valve 14 through the intake hole 41, the air valve 14 is pressed against the peripheral edge of the valve seat opening 46 and the valve seat opening 46 is reliably closed. .

  Thereafter, as shown in FIG. 5, the pouring container 1 is returned to the upright posture and the pressing of the double container 4 is stopped to stop the outflow of the contents from the communication opening 52. Then, the pressing force by the contents applied to the film 13 is released, and the film 13 separated from the upper surface of the top wall portion 11 is restored to the original state and is in close contact with the upper surface of the top wall portion 11. As a result, the spout 27 is closed and the communication opening 52 is sealed by the film 13, and the hermeticity of the inner container 2 is ensured again.

  Here, when the pressing of the double container 4 is released in a state in which the sealing performance of the inner container 2 is ensured, the outer container 3 tends to be restored and deformed while the inner container 2 is deformed and deformed. At this time, the negative pressure generated between the inner container 2 and the outer container 3 acts on the air valve 14 through the intake hole 41, so that the air valve 14 is separated from the valve seat opening 46 and the outside air inflow path 40. The outside and the intake hole 41 communicate with each other. Then, outside air flows into the outside air inflow path 40 from the outside, and this outside air is sucked between the inner container 2 and the outer container 3 through the intake hole 41. Therefore, after the contents are poured out from the dispensing container 1, an intermediate space 33 is formed between the inner container 2 and the outer container 3.

After the use of the dispensing container 1 is completed, the overcap 7 is rotated around the hinge portion 6 to attach the overcap 7 to the dispensing body 5. Then, in accordance with this mounting operation, the engaging portion 29 moves downward while the engaging protrusion 31 of the engaging portion 29 contacts the side end portion of the top wall portion 11 of the movable member 12 from the upper side. The portion 29 rotates the movable member 12 downward about the connecting hinge portion 25 to move downward. Thereby, the pouring valve 24 approaches downwardly toward the standing tube portion 20 of the mounting member 10, and the pouring valve 24 is fitted into the standing tube portion 20 of the mounting member 10. 24 blocks communication between the inside of the inner container 2 and the communication opening 52.
When the movable member 12 moves downward in this manner, the communicating cylinder portion 23 and the standing cylinder portion 20 are in sliding contact with each other, and the standing cylinder portion 20 guides the downward movement of the movable member 12, thereby moving the movable member. 12 will move down stably.

  Then, the lower end edge of the communication cylinder portion 23 comes into contact with the base wall portion 17 of the mounting member 10, the bridge portion 34 comes into contact with the upper end edge of the standing tube portion 20, etc. Is restricted, the engaging protrusion 31 of the engaging portion 29 climbs over the side end portion of the top wall portion 11 of the movable member 12 from above to below, and the engaging protrusion 31 is the side end portion of the top wall portion 11. It will be located below.

  Here, as shown in FIG. 5, when the dispensing container 1 is in the upright posture, the air valve 14 is separated from the valve seat opening 46. For example, the contents are dispensed as described above. Even when the outer container 3 is pushed inward in the radial direction by holding the double container 4 in a state where the intermediate space 33 is formed between the container 2 and the outer container 3, Air is released to the outside through the intake hole 41 and the outside air inflow path 40.
