Description

本発明は、容器を傾けることで内容物を注出する、注出容器に関する。 The present invention relates to a pouring container that pours out the contents by tilting the container.

従来、容器を傾けることで内容物を注出する注出容器であって、注出に伴って流入する空気を内容物と隔離する構造の注出容器が公知である。
例えば、吸気孔(空気取り入れ口5)と連通孔(ワイン取り出し口8)を有し、吸気孔(空気取り入れ口5)に隔離フィルム(袋状隔膜1)を接続した注出アダプター(安定注出器)を、隔離フィルム(袋状隔膜1)が注出容器内に収容されるように注出容器の注出口に取り付けた注出容器が特許文献1で公知である。この特許文献1で公知の注出容器は、連通孔(ワイン取り出し口8)の先に逆止弁(球6、球止め7)をさらに有しており、注出容器を傾けることで内容物(ワイン10)を取り出す際、注出容器内に流入しようとする空気を吸気孔(空気取り入れ口5)から取り入れることで、隔離フィルム(袋状隔膜1)が取り入れた空気により膨らみ、注出容器内の内容物(ワイン10)が取り出された分の空間を補填する。これによって、注出容器内に残った内容物(ワイン10)に直接空気が触れることがなく、内容物(ワイン10)の劣化を防止することができ、また、連通孔(ワイン取り出し口8)を空気が通過することがないため、内容物(ワイン10)取り出し時の脈動を防ぐことができる。
Conventionally, a pouring container for pouring out the contents by tilting the container and having a structure for separating the air flowing in with the pouring from the contents is known.
For example, an injection adapter (stable injection) having an intake hole (air intake port 5) and a communication hole (wine outlet port 8) and having an isolation film (bag-shaped diaphragm 1) connected to the intake hole (air intake port 5). A pouring container in which a container) is attached to a pouring outlet of a pouring container so that a separating film (bag-shaped diaphragm 1) is housed in the pouring container is known in Patent Document 1. The pouring container known in Patent Document 1 further has a check valve (ball 6, ball stopper 7) at the tip of the communication hole (wine outlet 8), and the contents can be obtained by tilting the pouring container. When the (wine 10) is taken out, the air that is about to flow into the pouring container is taken in through the intake hole (air intake port 5), so that the isolation film (bag-shaped diaphragm 1) inflates due to the air taken in and the pouring container. It fills the space where the contents (wine 10) are taken out. As a result, air does not come into direct contact with the contents (wine 10) remaining in the pouring container, deterioration of the contents (wine 10) can be prevented, and the communication hole (wine outlet 8) can be prevented from deteriorating. Since air does not pass through the wine, it is possible to prevent pulsation when the contents (wine 10) are taken out.

特許公開平2−57567号公報Patent Publication No. 2-57567

ところが、上記特許文献1で公知の注出容器は、未だ改善の余地があった。すなわち、隔離フィルム(袋状隔膜1)が注出アダプター(安定注出器)に設けられているため、空気を取り込んで膨らんだ隔離フィルム(袋状隔膜1)が注出容器の口部周辺を塞ぎ、内容物(ワイン10)の取り出しを阻害する虞があった。 However, the dispensing container known in Patent Document 1 still has room for improvement. That is, since the isolation film (bag-shaped diaphragm 1) is provided on the dispensing adapter (stable dispenser), the isolation film (bag-shaped diaphragm 1) that swells by taking in air covers the area around the mouth of the dispensing container. There was a risk of blocking and hindering the removal of the contents (wine 10).

また、内容物(ワイン10)充填前に注出アダプター(安定注出器)を取り付ける場合、注出アダプター(安定注出器)に設けられた連通孔(ワイン取り出し口8)から内容物(ワイン10)を充填するため、注出アダプター(安定注出器)を取り付けていない状態での充填に比べて時間がかかってしまい、生産速度が低下してしまう虞があった。
また、内容物(ワイン10)充填後に注出アダプター(安定注出器)を取り付ける場合、注出アダプター(安定注出器)や隔離フィルム(袋状隔膜1)が注出容器内に入る分、内容物(ワイン10)が注出容器から溢れ出てしまう虞や、予め溢れ出ない量の内容物(ワイン10)を充填するにしても、収縮した隔離フィルム(袋状隔膜1)の折り目部分等に空気が巻き込まれ、内容物(ワイン10)内に混ざってしまう虞があった。
When the pouring adapter (stable pouring device) is attached before filling the content (wine 10), the content (wine) is provided through the communication hole (wine outlet 8) provided in the pouring adapter (stable pouring device). Since 10) is filled, it takes longer than filling without the pouring adapter (stable pouring device) attached, and there is a risk that the production speed may decrease.
In addition, when the pouring adapter (stable pouring device) is attached after filling the contents (wine 10), the amount of the pouring adapter (stable pouring device) and the isolation film (bag-shaped diaphragm 1) that enter the pouring container is increased. There is a risk that the contents (wine 10) will overflow from the pouring container, and even if the contents (wine 10) are filled in an amount that does not overflow in advance, the creases of the shrinking isolation film (bag-shaped diaphragm 1) There was a risk that air would be caught in the contents (wine 10) and mixed in the contents (wine 10).

また、連通孔(ワイン取り出し口8)が小径であり、内容物(ワイン10)を取り出す際に容器を大きく傾ける必要があるため、内容物(ワイン10)をごく少量取り出したい場合、注出容器を傾ける角度の調節のみでは必要量以上の内容物(ワイン10)を取り出してしまう虞があった。 In addition, since the communication hole (wine outlet 8) has a small diameter and the container needs to be tilted greatly when the content (wine 10) is taken out, if a very small amount of the content (wine 10) is to be taken out, a pouring container is used. There was a risk that more than the required amount of contents (wine 10) would be taken out only by adjusting the tilting angle.

本発明は、これらの問題点を解決するものであり、簡単な構成で、隔離フィルムが内容物の取り出しを阻害することがなく、充填速度の低下や打栓時に注出容器から内容物の漏出がない注出容器を提供することを目的とするものである。 The present invention solves these problems. With a simple structure, the isolation film does not hinder the removal of the contents, and the filling speed is reduced or the contents leak from the pouring container at the time of plugging. The purpose is to provide a pouring container that is free of charge.

本発明の注出容器は、内容物を注出する注出口が設けられた口部と、前記口部から下方に延びる胴部と、前記胴部から下方に延びる底部とを有し、容器を傾けることで内容物を注出する注出容器であって、前記底部は、吸気孔と、前記吸気孔を開閉可能な吸気弁とを有し、該注出容器は、前記吸気孔を介して外部と連通して空気室を形成する隔離フィルムをさらに有し、前記底部は、底壁部および前記底壁部の下端に接続された底面を有し、前記底面には上方に盛り上がった底面凸部が形成され、前記吸気弁は、前記吸気孔から前記空気室への外気の流入を許容するように開口可能且つ、前記吸気孔から容器外への気体の流出を防止するように閉塞可能な逆止弁であり、前記隔離フィルムは、前記隔離フィルムの中央付近を前記吸気弁の天面に接続され、前記隔離フィルムの外周縁部を前記底壁部の前記底面からの立ち上がり部分に全周にわたって接続されていることにより、前記課題を解決するものである。 The pouring container of the present invention has a mouth portion provided with a spout for pouring out the contents, a body portion extending downward from the mouth portion, and a bottom portion extending downward from the body portion. A pouring container for pouring out contents by tilting, the bottom of which has an intake hole and an intake valve capable of opening and closing the intake hole, and the pouring container is provided through the intake hole. It further has an isolation film that communicates with the outside to form an air chamber , the bottom portion having a bottom wall portion and a bottom surface connected to the lower end of the bottom wall portion, and the bottom surface has a convex bottom surface that rises upward. A portion is formed, and the intake valve can be opened so as to allow the inflow of outside air from the intake hole to the air chamber, and can be closed so as to prevent the outflow of gas from the intake hole to the outside of the container. It is a check valve, and the isolation film is connected to the top surface of the intake valve near the center of the isolation film, and the outer peripheral edge portion of the isolation film is all around the rising portion of the bottom wall portion from the bottom surface. By being connected over , the above-mentioned problem is solved.

請求項1に係る注出容器によれば、吸気孔と、吸気孔を開閉可能な吸気弁とは、底部に設けられており、吸気孔を介して外部と連通して空気室を形成する隔離フィルムをさらに有していることで、注出容器の口部に干渉せず、内容物の充填を阻害することがなく、内容物を充填する前に注出容器内に隔離フィルムが設けられているため、注出容器の口部に栓をしても、内容物が溢れ出るようなことがない。
また、注出容器から内容物を取り出す際、内容物が取り出されることで注出容器内に発生する空隙を、吸気孔から空気室へ外気を取り込むことで補填するため、注出容器の口部から空気が流入し、内容物が空気に直接触れることがなく、内容物の劣化を防ぐことができる。
また、吸気孔には、吸気孔を開閉可能な逆止弁である吸気弁が設けられているため、必要量の内容物を取り出し終えて注出容器を静置した際に、吸気弁を閉栓することで、膨らんだ隔離フィルムを内容物が圧迫しても、吸気孔から空気室内の空気が注出容器外へ流出することがない。
また、底部の底面に上方に盛り上がった底面凸部を形成することで、底面の下面側に凹状の空間を設けることができ、これによって、吸気弁を底面の下端よりも下方に突出しない位置に設けることができるため、吸気弁に干渉することなく注出容器を安定して正立できるとともに、吸気弁の誤操作を防止できる。
また、隔離フィルムは底部に接続されているため、隔離フィルムの下方に内容物が滞留せず、内容物を取り出す際に、隔離フィルムによる流路の閉塞を防ぐことができる。
また、隔離フィルムは、吸気弁に接続されているため、非圧縮性の流体である内容物が常に吸気弁付近まで存在し、注出容器からの内容物を取り出した際、隔離フィルムの吸気弁に接続された箇所が内容物の動きに迅速に追従して吸気弁を素早く開放方向へ動作させるため、吸気弁に隔離フィルムが接続されていない場合に比べて、空気室内に吸気を開始するまでの応答速度を向上させることができる。
また、隔離フィルムは、外周縁部が底壁部の底面からの立ち上がり部分に全周にわたって接続されているため、隔離フィルムの下に内容物が潜り込むような大きな隙間が発生せず、注出容器内の内容物が少なくなっても、隔離フィルムが内容物を取り出すための流路をより一層閉塞することがなく、確実に内容物の全量を注出容器から取り出すことができる。
According to the injection container according to claim 1, the intake hole and the intake valve that can open and close the intake hole are provided at the bottom, and are isolated so as to communicate with the outside through the intake hole to form an air chamber. By further holding the film, the isolation film is provided in the dispensing container before filling the contents without interfering with the mouth of the dispensing container and hindering the filling of the contents. Therefore, even if the mouth of the pouring container is plugged, the contents will not overflow.
In addition, when the contents are taken out from the pouring container, the voids generated in the pouring container due to the contents being taken out are filled by taking in outside air from the intake hole into the air chamber, so that the mouth of the pouring container is filled. Air flows in from the air, and the contents do not come into direct contact with the air, so that deterioration of the contents can be prevented.
In addition, since the intake hole is provided with an intake valve that is a check valve that can open and close the intake hole, the intake valve is closed when the required amount of contents has been taken out and the pouring container is left to stand. As a result, even if the contents press the swollen isolation film, the air in the air chamber does not flow out of the injection container from the intake hole.
Further, by forming a bottom convex portion that rises upward on the bottom surface of the bottom portion, a concave space can be provided on the lower surface side of the bottom surface, whereby the intake valve is positioned so as not to protrude below the lower end of the bottom surface. Since it can be provided, the pouring container can be stably upright without interfering with the intake valve, and erroneous operation of the intake valve can be prevented.
Further, since the isolation film is connected to the bottom, the contents do not stay under the isolation film, and it is possible to prevent the flow path from being blocked by the isolation film when the contents are taken out.
Further, since the isolation film is connected to the intake valve, the contents of the incompressible fluid always exist near the intake valve, and when the contents are taken out from the pouring container, the intake valve of the isolation film is used. Since the part connected to the air intake valve quickly follows the movement of the contents and operates the intake valve in the opening direction quickly, until the intake air is started in the air chamber as compared with the case where the isolation film is not connected to the intake valve. Response speed can be improved.
In addition, since the outer peripheral edge of the isolation film is connected to the rising portion of the bottom wall portion from the bottom surface over the entire circumference, a large gap for the contents to slip under the isolation film does not occur, and the pouring container is used. Even if the contents inside are reduced, the isolation film does not further block the flow path for taking out the contents, and the entire amount of the contents can be surely taken out from the pouring container.

請求項に記載の構成によれば、吸気弁は、吸気孔よりも径が大きい平板状に形成された圧力板と、圧力板の中央から突出し、吸気孔を摺動可能な摺動部と、圧力板及び摺動部を閉栓方向に付勢する付勢部材とを有しているため、吸気弁は逆止弁として機能し、必要量の内容物を取り出し終えた際、付勢部材によって迅速に吸気孔を閉栓することで、内容物が隔離フィルムを圧迫しても、空気室内の空気が注出容器外へ流出することを防止できる。 According to the configuration according to claim 2 , the intake valve includes a pressure plate formed in a flat plate shape having a diameter larger than that of the intake hole, and a sliding portion that protrudes from the center of the pressure plate and allows the intake hole to slide. Since it has an urging member that urges the pressure plate and the sliding part in the closing direction, the intake valve functions as a check valve, and when the required amount of contents is taken out, the urging member causes it. By closing the air intake hole quickly, even if the contents press the isolation film, it is possible to prevent the air in the air chamber from flowing out of the pouring container.

請求項に記載の構成によれば、少なくとも底部を含む部分は、口部を含む部分と別体として構成されているため、隔離フィルムや吸気弁を底部に取り付ける際に、狭い口部を通過することなく底部に直接取り付け作業をすることができる。 According to the configuration according to claim 3 , at least the portion including the bottom portion is configured as a separate body from the portion including the mouth portion, and therefore, when the isolation film or the intake valve is attached to the bottom portion, the portion passes through the narrow mouth portion. It can be attached directly to the bottom without any effort.

請求項に記載の構成によれば、摺動部の外周面には、圧力板から突出方向に向かって延びる通気溝が設けられているため、より迅速に吸気できる。 According to the fourth aspect, since the outer peripheral surface of the sliding portion is provided with a ventilation groove extending from the pressure plate in the projecting direction, intake air can be taken more quickly.

請求項に記載の構成によれば、摺動部の先端には、吸気孔よりも径が大きく、吸気孔の外側から吸気弁を開栓方向へ押圧可能な開口ボタンが設けられているため、内容物の充填時に開口ボタンを押圧しておくことで、空気室内の空気を排出しながら内容物を注出容器内に十分に充填することができる。 According to the configuration of claim 5 , the tip of the sliding portion is provided with an opening button having a diameter larger than that of the intake hole and capable of pressing the intake valve from the outside of the intake hole in the opening direction. By pressing the opening button when filling the contents, the contents can be sufficiently filled in the pouring container while discharging the air in the air chamber.

請求項に記載の構成によれば、注出口には、注出口に嵌着する注出アダプターが設けられ、注出アダプターには、注出容器内外を連通し、注出口の内径よりも小径な連通孔が設けられているため、内容物を取り出す際、連通孔からの空気の流入を防ぐことができる。 According to the configuration of claim 6 , the spout is provided with a spout adapter that fits into the spout, and the spout adapter communicates with the inside and outside of the spout container and has a diameter smaller than the inner diameter of the spout. Since the communication holes are provided, it is possible to prevent the inflow of air from the communication holes when taking out the contents.

The air chamber 116 is separated from the air chamber 116 by an isolation film 117 formed in the form of a thin film.
In the isolation film 117, the vicinity of the center is connected to the top surface of the pressure plate 127, and the outer peripheral edge portion is connected to the rising portion of the bottom wall portion 121 from the bottom surface 123 over the entire circumference. The connection method between the two is preferably adhesion or welding.

次に、注出容器100への内容物Sの充填について、図6に基づいて説明する。
まず、充填ノズル(図示しない)を口部111の注出口112に合わせて、図6(a)に示すように、内容物Sを注出容器100の貯留室115内に充填する。
このとき、注出アダプター140は注出口112にまだ取り付けられておらず、注出口112は連通孔141に比べて大きく開口しているため、迅速に内容物Sの充填が可能となる。
Next, the filling of the content S into the pouring container 100 will be described with reference to FIG.
First, the filling nozzle (not shown) is aligned with the spout 112 of the mouth portion 111, and the content S is filled into the storage chamber 115 of the pouring container 100 as shown in FIG. 6A.
At this time, the pouring adapter 140 is not yet attached to the pouring outlet 112, and the pouring outlet 112 has a larger opening than the communication hole 141, so that the content S can be filled quickly.

また、容器上部110と底部120とは、下部接続部114が上部接続部122と圧入嵌合することで、容器上部110と底部120との境界を隙間なく接続されているため、注出容器100内に内容物Sを充填しても、容器上部110と底部120との接続部から内容物Sが注出容器100外へ漏れ出すことがない。
また、内容物Sの充填前に空気室116内に外気Aが流入していた場合、内容物Sの充填中に吸気弁126の開口ボタン132を押し開放しておくことで、充填された内容物Sによって隔離フィルム117越しに空気室116が圧迫され、吸気孔125から空気室116内の余分な外気Aを注出容器100外へ排出でき、図6(b)に示すように、所定量の内容物Sを、注出容器100外へ溢れさせることなく確実に貯留室115内に充填することができる。
Further, since the lower connection portion 114 is press-fitted with the upper connection portion 122 to connect the boundary between the container upper portion 110 and the bottom portion 120 without a gap between the container upper portion 110 and the bottom portion 120, the pouring container 100 Even if the content S is filled inside, the content S does not leak out of the pouring container 100 from the connection portion between the top 110 and the bottom 120 of the container.
Further, when the outside air A has flowed into the air chamber 116 before the content S is filled, the filled content is filled by pressing and opening the opening button 132 of the intake valve 126 during the filling of the content S. The air chamber 116 is pressed through the isolation film 117 by the object S, and the excess outside air A in the air chamber 116 can be discharged from the intake hole 125 to the outside of the pouring container 100. As shown in FIG. 6B, a predetermined amount can be discharged. The contents S of the above can be reliably filled in the storage chamber 115 without overflowing to the outside of the pouring container 100.

所定量の内容物Sを貯留室115内に充填した後、図6(c)に示すように、注出口112に注出アダプター140及び密閉栓142を嵌合させることで、注出容器100への内容物Sの充填及び注出容器100の密閉が完了する。 After filling the storage chamber 115 with a predetermined amount of the content S, as shown in FIG. 6C, the pouring adapter 140 and the sealing stopper 142 are fitted to the pouring outlet 112 to fill the pouring container 100. The filling of the contents S and the sealing of the pouring container 100 are completed.

次に、注出容器100からの内容物Sの取り出しについて、図7に基づいて説明する。なお、説明のため、注出容器100は静置したままの図を用いる。
まず、密閉栓142を注出アダプター140から取り去り、注出容器100を傾けると、内容物Sは自重によって連通孔141を通過し注出容器100外へ取り出される。
Next, the removal of the content S from the pouring container 100 will be described with reference to FIG. 7. For the sake of explanation, the drawing of the pouring container 100 as it is left standing is used.
First, when the sealing stopper 142 is removed from the pouring adapter 140 and the pouring container 100 is tilted, the content S passes through the communication hole 141 by its own weight and is taken out of the pouring container 100.

このとき、注出容器100内は、内容物Sが取り出された分負圧状態となるため、外気Aを吸引しようとする力が発生するが、注出口112は連通孔141によって開口面積を狭めてあるとともに、吸気弁126が外気Aを吸引しようとする力によって開放されるため、口部111側から貯留室115内に外気Aが流入せず、図7(a)に示すように、空気室116にのみ底部120の吸気孔125(通気溝130)を介して外気Aが流入する。
これによって、貯留室115内の内容物Sには、外気Aが直接触れることはないため、貯留室115内の内容物Sの劣化を防ぐことができる。
At this time, since the inside of the pouring container 100 is in a negative pressure state due to the extraction of the contents S, a force for sucking the outside air A is generated, but the pouring outlet 112 narrows the opening area by the communication hole 141. Since the intake valve 126 is opened by the force that tries to suck the outside air A, the outside air A does not flow into the storage chamber 115 from the mouth 111 side, and as shown in FIG. 7A, air does not flow into the storage chamber 115. The outside air A flows into the chamber 116 only through the intake hole 125 (ventilation groove 130) of the bottom 120.
As a result, since the outside air A does not come into direct contact with the contents S in the storage chamber 115, deterioration of the contents S in the storage chamber 115 can be prevented.

また、隔離フィルム117の中央部は圧力板127に接続されているため、内容物Sが非圧縮性の液体である場合、内容物Sは常に圧力板127付近まで存在し、内容物Sを注出容器100外へ取り出し始めた際に、隔離フィルム117越しに圧力板127が内容物Sの動きに迅速に追従して吸気弁126を素早く開放方向へ動作させる。
これによって、圧力板127に隔離フィルム117が接続されていない場合に比べて、空気室116内に吸気を開始するまでの応答速度を向上できる。
さらに、吸気弁126の圧力板127の外周縁部には、下方に突出した環状の閉塞リング128が設けられており、吸気弁126の摺動部129には、圧力板127から突出方向に向かって延びる通気溝130が設けられているため、吸気孔125は通気溝130によって開口しており、閉塞リング128と底面凸部124との接触状態のみで吸気弁126の開閉が可能であることから、圧力板127の動作に対してより迅速に吸気弁126を開閉することができる。
Further, since the central portion of the isolation film 117 is connected to the pressure plate 127, when the content S is an incompressible liquid, the content S always exists up to the vicinity of the pressure plate 127, and the content S is poured. When the container 100 is taken out of the container 100, the pressure plate 127 quickly follows the movement of the content S through the isolation film 117 to quickly operate the intake valve 126 in the opening direction.
As a result, the response speed until the start of intake air into the air chamber 116 can be improved as compared with the case where the isolation film 117 is not connected to the pressure plate 127.
Further, an annular closing ring 128 projecting downward is provided on the outer peripheral edge of the pressure plate 127 of the intake valve 126, and the sliding portion 129 of the intake valve 126 faces the protruding direction from the pressure plate 127. Since the ventilation groove 130 is provided, the intake hole 125 is opened by the ventilation groove 130, and the intake valve 126 can be opened and closed only in the contact state between the closing ring 128 and the bottom convex portion 124. , The intake valve 126 can be opened and closed more quickly with respect to the operation of the pressure plate 127.

また、吸気弁126開放後は内容物Sが取り出される度に吸気孔125(通気溝130)から迅速に外気Aが補填されるため、より確実に連通孔141からの外気Aの流入が防止でき、内容物S取り出し時の脈動を防ぐことができる。
さらに、開口ボタン132の吸気孔125側の係合筒部135の端部には切欠き部133が設けられているため、吸気時に底面凸部124と開口ボタン132とが密着しても、切欠き部133から空気室116へ吸気が可能となり、開口ボタン132を押し込み過ぎる等の不意な吸気弁126の閉塞による、連通孔141からの貯留室115内への外気Aの取り込みを防ぐことができる。
Further, after the intake valve 126 is opened, the outside air A is quickly replenished from the intake hole 125 (vent groove 130) every time the content S is taken out, so that the inflow of the outside air A from the communication hole 141 can be prevented more reliably. , It is possible to prevent pulsation when the content S is taken out.
Further, since the notch 133 is provided at the end of the engaging cylinder 135 on the intake hole 125 side of the opening button 132, even if the bottom convex portion 124 and the opening button 132 are in close contact with each other during intake, the opening button 132 is cut. It is possible to take in air from the notch 133 to the air chamber 116, and it is possible to prevent the outside air A from being taken into the storage chamber 115 from the communication hole 141 due to an unexpected blockage of the intake valve 126 such as pushing the opening button 132 too much. ..

内容物Sがさらに注出容器100外へ取り出されると、図7(b)に示すように、隔離フィルム117は取り込んだ外気Aによって膨らむため、貯留室115の容積は縮小し、空気室116の容積が拡大する。
このとき、隔離フィルム117は、中央付近が圧力板127の天面に接続されているとともに、外周縁部が底壁部121の底面123からの立ち上がり部分に全周にわたって接続されており、隔離フィルム117の下に内容物Sが潜り込むような大きな隙間が発生しないため、注出容器100内の内容物Sが少なくなっても、隔離フィルム117が内容物Sを取り出すための流路を閉塞することがなく、確実に内容物Sの全量を注出容器100から取り出すことができる。
When the content S is further taken out of the pouring container 100, as shown in FIG. 7B, the isolation film 117 is inflated by the taken-in outside air A, so that the volume of the storage chamber 115 is reduced and the volume of the air chamber 116 is reduced. The volume expands.
At this time, the isolation film 117 is connected to the top surface of the pressure plate 127 near the center and the outer peripheral edge portion is connected to the rising portion of the bottom wall portion 121 from the bottom surface 123 over the entire circumference. Since a large gap for the contents S to slip under the 117 does not occur, the isolation film 117 blocks the flow path for taking out the contents S even if the contents S in the pouring container 100 are reduced. The entire amount of the content S can be reliably taken out from the pouring container 100.

また、内容物Sの全量を注出容器100から取り出さずに貯留室115内に保管する場合においても、内容物Sが隔離フィルム117越しに空気室116を圧迫するが、図7(c)に示すように、吸気弁126は開口ボタン132を押され続けていない限り、閉塞バネ131の付勢力と、隔離フィルム117越しに圧力板127に受ける内容物Sの自重によって閉栓方向に付勢されるため、空気室116内に流入した外気Aは空気室116内に留まり、空気室116の容積を保持する。
これによって、貯留室115の容積が拡大することはなく、密閉栓142を嵌合しないまま、内容物Sの残っている注出容器100を静置しても、連通孔141から貯留室115内に外気Aが取り込まれることはない。
Further, even when the entire amount of the content S is stored in the storage chamber 115 without being taken out from the pouring container 100, the content S presses the air chamber 116 through the isolation film 117, as shown in FIG. 7 (c). As shown, the intake valve 126 is urged in the closing direction by the urging force of the closing spring 131 and the weight of the content S received by the pressure plate 127 through the isolation film 117 unless the opening button 132 is continuously pressed. Therefore, the outside air A that has flowed into the air chamber 116 stays in the air chamber 116 and holds the volume of the air chamber 116.
As a result, the volume of the storage chamber 115 does not increase, and even if the pouring container 100 in which the content S remains is left standing without fitting the sealing plug 142, the inside of the storage chamber 115 through the communication hole 141. The outside air A is not taken into the air.

必要量の内容物Sを注出容器100から取り出し、注出容器100を静置した後、連通孔141に密閉栓142を圧入嵌合させることで、連通孔141は閉栓され、次に内容物Sを取り出す機会まで、貯留室115内の内容物Sを外気Aに触れることなく安全に保管することができる。 The required amount of the content S is taken out from the pouring container 100, the pouring container 100 is allowed to stand, and then the communication hole 141 is press-fitted into the communication hole 141 to close the communication hole 141, and then the content. Until the opportunity to take out S, the contents S in the storage chamber 115 can be safely stored without touching the outside air A.
