- This invention is made in view of such a situation, Comprising: While providing the quality of the content, providing the discharge container which can prevent the liquid leak from a discharge port, without increasing a number of parts. Objective.
- the present invention provides a slit valve structure discharge valve that can maintain the thickness and shape of a normal slit valve, exhibit a high check function, reduce the unit consumption of expensive soft elastic material,
- An object of the present invention is to provide a discharge container capable of obtaining a degree of design freedom.
- a discharge container is a container having an 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 main body and a discharge cap that is attached to the mouth portion of the container main body and that has a discharge hole that discharges the contents and a communication hole that communicates between the discharge port and the inside of the inner container.
- the outer container is formed with an intake hole for sucking outside air between the inner container and the outer container.
- the discharge cap includes an air valve that switches between communication and blocking between the outside of the discharge cap and the intake hole, and an elastically deformable discharge film that closes the discharge port.
- the discharge film has a slit, and the discharge film is elastically deformed as the internal pressure of the inner container increases, so that the slit is opened and the discharge port is opened.
- the discharge cap in the discharge container according to the first aspect, includes an outside air introduction hole that communicates the outside with the intake hole, and communication and blocking between the discharge port and the communication hole. And a valve member for switching between. Further, the air valve switches between communication and blocking between the intake hole and the outside air introduction hole, and the communication hole communicates with the inside of the inner container, and from the mouth of the container body to the container axial direction. Is formed at the top of the top cylindrical body projecting toward the outside of the container main body.
- the outer container of the container main body is squeezed (elastically deformed).
- the inner container is deformed together with the outer container to reduce the volume.
- the internal pressure of an inner container turns into a positive pressure with this volume reduction deformation
- the valve member is opened by this positive pressure, and the discharge port communicates with the inside of the inner container through the communication hole.
- the weight of the contents also acts on the valve member.
- the valve member is closed, and the communication through the communication hole between the discharge port and the inside of the inner container is blocked. Then, the discharge film is restored and deformed by the elastic restoring force, the slit is closed, and the discharge port is closed.
- the valve member By closing the valve member in this way, the inner container is sealed, and when the squeeze deformation described above is released, the outer container is subjected to a restoring deformation force.
- the negative pressure generated between the outer container and the inner container acts on the air valve through the intake hole, whereby the air valve is activated, and the intake hole and the outside communicate with each other through the external air introduction hole. Is inhaled between the outer container and the inner container.
- the air valve When the internal pressure between the outer container and the inner container rises to the atmospheric pressure due to the intake of the outside air, 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 in a shut-off state, so the internal pressure between the outer container and the inner container becomes positive pressure, and the inner container is deformed and deformed by this positive pressure. Is done. By reducing the volume of the inner container, the same action as described above is obtained, and the contents are discharged.
- the valve member is closed and the inner container is sealed except when discharging the contents, so that the quality of the contents is ensured.
- the discharge port is not opened until the discharge film is elastically deformed and the slit is expanded. For this reason, the sealing property of the discharge container is enhanced. Therefore, even if the contents remain between the discharge port and the valve member after the discharge, the content is prevented from leaking unintentionally from the discharge port.
- the discharge container according to the above aspect has a configuration in which the discharge film is restored and deformed to close the slit, the liquid discharge property of the discharge port is enhanced and the dripping of the contents is prevented.

- the discharge container according to the above aspect has a tubular body with a communication hole having a communication hole communicating with the inside of the inner container and projecting from the mouth of the container body toward the outside of the container body along the container axial direction. It is formed at the top.
- the distance between the communication hole and the discharge port can be reduced, and the space generated between them can be reduced. And when the space between a communicating hole and a discharge outlet is made small in this way, the quantity of the content which retains in this space can be suppressed. As a result, unintentional leakage of contents from the discharge port can be prevented more reliably.

- the suppression unit that applies a suppression force to the flow of the contents is positioned near the inside of the discharge film.
- the outer container when the pressing force against the container main body is removed, the outer container attempts to return to its original shape by its restoring force, so that decompression occurs in the container main body.
- the air valve opens quickly, and the outside air is sucked in between the outer container and the generated decompression is extinguished.
- the reduced pressure also acts on the discharge film.
- the discharge film since the contents are stored inside the discharge film in a state where the flow is suppressed by the suppressing portion, that is, in a state where the contents are difficult to move, the discharge film cannot be opened quickly. As a result, the check valve function can be surely exhibited in a state where pressure is reduced.
- the check valve function can be more reliably exhibited in the state where the occurrence of the occurrence of the problem.
- the suppressing portion exerts a suppressing action on the discharged contents.
- This suppression action has such an effect that the pressing force applied to the container body needs to be slightly increased when the discharge film is opened to discharge the contents. In other words, there is no inconvenience caused by this influence in actual use.
- the reliable check valve function exhibited by the discharge film can be obtained by the combination with the suppression unit, that is, the flow suppression effect of the suppression unit with respect to the contents located inside the discharge film.

Abstract
Description
そして、このように弁部材が開けられることにより、内容器の内圧(正圧)、更には容器本体を傾けている場合には内容物の自重が吐出膜に作用して、吐出膜は弾性変形しスリットが拡開し、吐出口が開かれる。その結果、内容器に収容された内容物が吐出口から吐出される。
この状態から、再び容器本体の外容器をスクイズ変形させると、空気弁は遮断状態であるため、外容器と内容器との間の内圧が正圧となり、この正圧によって内容器が減容変形される。内容器が減容変形されることにより、前述と同様の作用が得られ、内容物が吐出される。
また、上記態様に係る吐出容器は、吐出膜の弾性変形及び復元変形によって吐出口を開閉させる簡単な構成を備えるため、部品点数が削減でき、且つ、前述の顕著な効果を奏することができる。さらに、上記態様に係る吐出容器は、連通孔が、内容器の内部に連通するとともに、容器本体の口部から容器軸方向に沿う前記容器本体の外側に向けて突出する有頂筒状体の頂部に形成されている。このため、連通孔と吐出口との間の距離を近づけて、これらの間に生じるスペースを小さくすることができる。そして、このように、連通孔と吐出口との間のスペースを小さくした場合には、このスペースに滞留する内容物の量を抑制できる。この結果、吐出口から意図せず内容物が漏れ出るようなことが一層確実に防止される。
以下、図面を参照し、本発明の第一実施形態に係る吐出容器について説明する。
そして、外気が吸入されることにより、外容器3と内容器2との間の内圧が大気圧まで上昇すると、空気弁15cが復元変形して吸気孔8cと外気導入孔11dとを遮断する。このように、外容器3と内容器2との間に外気が吸入されることにより、内容器2の減容形状が保持される。
図4は、外容器3と内容器2との間に外気が吸入されている状態を示している。
吐出後は、開閉操作片7gを操作してオーバーキャップ7を閉めるとともに、吐出キャップ6に装着する。
また、吐出膜20が復元変形してスリット20aが閉じることにより、吐出口5の液切れ性が高められているとともに、内容物の液垂れも防止されている。
また、吐出膜20の弾性変形及び復元変形によって吐出口5を開閉させる簡単な構成を有するため、部品点数が削減されながらも、前述の顕著な効果を奏する。
以下、本発明の第二実施形態を、図面を参照しながら説明する。
図5は、本実施形態に係る吐出容器200の蓋体部(オーバーキャップ)216を閉じた状態を示す図であって一部を破断させた全体図である。容器体(容器本体)201は、図6に示すように、外層(外容器)202と内層(内容器)203とを有する。容器体201は、ブロー成形されて、デラミボトルタイプの容器として構成されている。外層202は、低密度ポリエチレン製であり、スクイズ変形可能で復元自在な可撓性を有する。内層203はナイロン製であり、外層202に剥離可能に積層されている。また、内層203は、粘稠性を有する内容物Nを収容し、内圧の減少により自在に減容変形する袋状に成形されている。
図5に示した、蓋体部216が閉じられた状態では、蓋体部216の押さえ頂板218が、吐出弁223に対して接触した状態、もしくはきわめて近接して配置されて、吐出弁223が開く動作を引き起こすことを防ぐように構成されている。そのため、胴部207に押圧力が作用する等により、容器体201の内圧が上昇しても、吐出弁223は押さえ頂板218に押さえられて弁開動作を引き起こすことができず、容器は内容物Nの不用意な吐出を生じない状態に安全に保持される。
