  However, the conventional discharge container has room for improvement in suppressing liquid dripping.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to suppress dripping.

In order to solve the above problems, the present invention proposes the following means.
A discharge container according to the present invention is a container having a flexible inner container in which contents are accommodated and squeezed and deformed as the contents are reduced, and an outer container in which the inner container is housed and elastically deformable. A discharge cap provided with a main body and a discharge cap that is attached to a mouth portion of the container main body and has a discharge hole for discharging contents, wherein the outer container has an outside air between the inner container and the outer container. An intake hole for inhaling air, and the discharge cap closes the top cylindrical cap body having the top wall portion on which the discharge hole is formed, the mouth of the inner container, and the inner container An inner plug having a communication hole communicating with the discharge hole, and disposed between the inner plug and the top wall portion, and the communication hole is freely closed, and the top wall portion The communication hole is opened by elastic displacement toward the upper side. A discharge valve, an elastically deformable discharge film having a slit for closing the discharge hole and opening the discharge hole at the time of expansion, an outside air introduction hole formed in the cap body, and the intake hole. An air valve that switches between communication and blocking thereof, and a valve cylinder provided between the inner plug and the cap body, the valve cylinder includes an outer cylinder portion provided with the air valve; And an inner cylinder part that communicates the discharge hole and the communication hole, and the discharge valve is formed such that a part of its outer peripheral edge part is elastically deformable. By being connected to the inner cylinder portion via a single connecting piece, the connecting piece is disposed so as to be rotatable upward around the connecting piece.

In the discharge container according to the present invention, when the contents stored in the inner container of the container main body are discharged, the outer container of the container main body is squeezed (elastically deformed), and the inner container is deformed and deformed together with the outer container. Then, the internal pressure of the inner container becomes a positive pressure, and the positive pressure acts on the discharge valve, whereby the connecting piece is elastically deformed, and the discharge valve rotates around the connecting piece to open the communication hole. Thereby, the discharge hole and the inside of the inner container communicate with each other through the communication hole, and the internal pressure (positive pressure) of the inner container acts on the discharge film, and the discharge film is elastically deformed. As a result, the slit is widened to open the discharge hole, and the contents stored in the inner container are discharged from the discharge hole.
When the internal pressure of the inner container is reduced, the discharge valve is restored and displaced based on the restoring force of the connecting piece, and the discharge valve is rotated around the connecting piece to close the communication hole. Communication through the communication hole is blocked. Further, the discharge film is restored and deformed by the elastic restoring force, the slit is closed, and the discharge hole is closed.
When the above-described squeeze deformation is released, the outer container tends to be restored and deformed. At this time, if the discharge valve closes the communication hole and the inner container is sealed, a negative pressure is generated between the outer container and the inner container, and this negative pressure acts on the air valve through the intake hole. The air valve is activated. As a result, the intake hole and the outside communicate with each other through the outside air introduction hole, and the outside air is sucked between the outer container and the inner container. When the internal pressure between the outer container and the inner container rises to atmospheric pressure, the air valve is restored and deformed to block the intake hole and the outside air introduction hole. Thus, the volume reduction shape of the inner container is maintained by sucking the outside air between the outer container and the inner container.
From this state, when the outer container of the container body is squeezed again, the air valve is shut off, so the internal pressure between the outer container and the inner container becomes positive, and this positive pressure reduces the inner container. The contents are deformed and the contents are discharged as described above.
According to this discharge container, after the contents are discharged from the discharge holes, the discharge film is restored and deformed, and the slits are closed, thereby improving the drainage of the discharge holes and suppressing the dripping of the contents. it can. In addition, at this time, since the discharge valve is restored and displaced based on the restoring force of the connecting piece and the communication hole is closed, the suck back effect accompanying the movement of the discharge valve promotes the restoration deformation of the discharge film, and the vicinity of the discharge hole. The contents can be drawn in, and the dripping of the contents can be effectively suppressed. Furthermore, at this time, the discharge valve rotates around the connecting piece and closes the communication hole, it becomes possible to secure a large amount of movement of the discharge valve, and enhance the suck back effect accompanying the movement of the discharge valve, The dripping of the contents can be suppressed more effectively.

  The inner plug may be provided with a partition portion that partitions the communication hole into a first partition hole located on the connection piece side and a second partition hole located on the anti-connection piece side in a plan view of the communication hole. .

  In this case, since the partition portion is provided in the inner plug, when the positive pressure in the inner container acts on the discharge valve, among the discharge valves, the proximal end portion located on the connecting piece side in the plan view of the discharge valve and A positive pressure can be applied to any of the tip portions located on the side opposite to the connection side. As a result, the positive pressure in the inner container can be effectively applied to the discharge valve, and the discharge valve can be easily rotated around the connecting piece. Therefore, for example, even when the outer container is small and squeezed and deformed, it is possible to reliably open the communication hole by rotating the discharge valve with high sensitivity. Furthermore, when the outer container is greatly squeezed and deformed, the discharge valve can be greatly rotated to increase the suck back effect when the discharge valve is restored and the dripping of the contents is more effectively suppressed. can do.

  According to the present invention, dripping can be suppressed.

The located partition hole is the second partition hole 37.
As shown in FIG. 1, the lid 28 is integrally connected to the cap body 23 via a hinge portion.

  Next, the operation of the discharge container 10 will be described.

  In the discharge container 10, when the contents M accommodated in the inner container 11 of the container body 13 are discharged, the cover 28 is opened, and the discharge posture is such that the discharge film 24 faces obliquely downward as shown in FIG. 4. In this state, the outer container 12 of the container body 13 is squeezed (elastically deformed). Thereby, the inner container 11 is deformed together with the outer container 12 to reduce the volume. In addition, as shown in FIG. 4, when the space which the communication with the exterior was interrupted | blocked by the air valve 26 between the inner container 11 and the outer container 12 is formed, squeeze deformation of the outer container 12 is carried out. Thus, this space becomes positive pressure and the inner container 11 is deformed and deformed.

  Then, along with this volume reduction deformation, the internal pressure of the inner container 11 becomes a positive pressure, and this positive pressure acts on the discharge valve 27. At this time, a positive pressure can be applied to both the proximal end portion located on the connecting piece 50 side and the distal end portion located on the anti-connecting piece side in the plan view of the discharge valve 27. As a result, the connecting piece 50 is elastically deformed and the discharge valve 27 rotates around the connecting piece 50, and the distal end portion of the discharge valve 27 is farther away from the bottom wall portion 21 a of the inner plug 21 than the base end portion. The hole 34 is opened. Then, the discharge hole 22 and the inside of the inner container 11 communicate with each other through the communication hole 34, and the internal pressure (positive pressure) of the inner container 11 acts on the discharge film 24 and the discharge film 24 is elastically deformed. As a result, the slit 49 is expanded to open the discharge hole 22, and the content M accommodated in the inner container 11 is discharged from the discharge hole 22.

  Thereafter, when the internal pressure of the inner container 11 decreases, as shown in FIGS. 5 and 6, the discharge valve 27 is restored and displaced based on the restoring force of the connecting piece 50, and the discharge valve 27 rotates around the connecting piece 50. Thus, the communication hole 34 is closed, and the communication through the communication hole 34 between the discharge hole 22 and the inside of the inner container 11 is blocked. Further, the discharge film 24 is restored and deformed by the elastic restoring force, the slit 49 is closed, and the discharge hole 22 is closed.

When the above-described squeeze deformation is released, the outer container 12 tries to be restored and deformed. At this time, if the discharge valve 27 closes the communication hole 34 and the inner container 11 is sealed, a negative pressure is generated between the outer container 12 and the inner container 11, and this negative pressure passes through the air intake hole 15 and air is discharged. The air valve 26 operates by acting on the valve 26. Thereby, the intake hole 15 and the outside communicate with each other through the outside air introduction hole 46, and the outside air is sucked between the outer container 12 and the inner container 11. When the internal pressure between the outer container 12 and the inner container 11 rises to atmospheric pressure, the air valve 26 is restored and deformed, and the intake hole 15 and the outside air introduction hole 46 are blocked. As described above, when the outside air is sucked between the outer container 12 and the inner container 11, the volume reduction shape of the inner container 11 is maintained.
From this state, when the outer container 12 of the container body 13 is squeezed again, as described above, the air valve 26 is shut off, so that the internal pressure between the outer container 12 and the inner container 11 is positive. The inner container 11 is reduced in volume by this positive pressure, and the contents M are discharged.

  As described above, according to the discharge container 10 according to the present embodiment, after the content M is discharged from the discharge hole 22, the discharge film 24 is restored and deformed, and the slit 49 is closed. While improving cutting property, the dripping of the content M can also be suppressed. In addition, at this time, the discharge valve 27 is restored and displaced based on the restoring force of the connecting piece 50 and closes the communication hole 34. Therefore, due to the suck back effect accompanying the movement of the discharge valve 27, the restoring deformation of the discharge film 24 is promoted. However, the content M in the vicinity of the discharge hole 22 can be drawn in, and the dripping of the content M can be effectively suppressed. Further, at this time, as shown in FIG. 5, the discharge valve 27 rotates around the connecting piece 50 and closes the communication hole 34, so that a large amount of movement of the discharge valve 27 can be secured. The suck back effect accompanying the movement of the valve 27 can be enhanced, and the dripping of the contents M can be more effectively suppressed.

  In addition, since the partition portion 35 is provided in the inner plug 21, when the positive pressure in the inner container 11 acts on the discharge valve 27, among the discharge valves 27, the proximal end portion and the distal end portion of the discharge valve 27. Positive pressure can be applied to both. Thereby, the positive pressure in the inner container 11 can be effectively applied to the discharge valve 27, and the discharge valve 27 can be easily rotated around the connecting piece 50. Therefore, for example, even when the outer container 12 is small and squeezed, the discharge valve 27 can be rotated with high sensitivity and the communication hole 34 can be reliably opened. Further, when the outer container 12 is greatly squeezed, the discharge valve 27 can be greatly rotated to enhance the suck back effect when the discharge valve 27 is restored and the liquid content of the contents M is further reduced. It can be effectively suppressed.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the container body 13 is a delami bottle in which the inner container 11 is detachably laminated on the inner surface of the outer container 12, but the present invention is not limited to this, and for example, the inner container 11 and the outer container 12. And may be a double container formed separately. However, a delami bottle is preferable because versatility can be improved.

  In the above embodiment, the lid 28 is provided. However, the lid 28 may not be provided. Further, when the lid body 28 is provided, the cap body 23 may not be connected to the cap body 23 via the hinge portion. However, it is preferable to connect the lid body 28 to the cap body 23 via the hinge portion because the lid body 28 can be opened and closed with one touch, for example, and it is easy to use, and the lid body 28 can be prevented from being lost.

In the above embodiment, the discharge film 24 is attached to the valve cylinder 25 via the attachment cylinder 44, but the present invention is not limited to this. For example, the discharge film 24 may be fixed to the throttle portion 48 of the discharge hole 22.
Moreover, the partition part 35 may not be present.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
