またシール筒53に代えて、基台51の下面にスパウト12の口部13の先端面に当接する凸状の突起(図示省略)等を形成してシールを行うようにしてもよく、基台51の下面とスパウト12の口部13の先端面とが密着して十分にシールを行うことが可能であれば、シール筒53等のシール手段を特に設けなくてもよい。
Further, instead of the seal cylinder 53, a convex protrusion (not shown) or the like that abuts on the front end surface of the mouth portion 13 of the spout 12 may be formed on the lower surface of the base 51 for sealing. If the lower surface of 51 and the front end surface of the mouth portion 13 of the spout 12 are in close contact and can be sufficiently sealed, it is not necessary to provide a sealing means such as the seal cylinder 53.
フィルム61は、薄膜状のフィルムであり、可撓性、柔軟性、伸縮性を有する薄膜フィルムが含まれる。フィルム61の厚さは、特に限定されるものではなく用途、内容物、材質等に応じて適宜選択して使用することができる。但し、フィルム61及び基台51の上面とキャップ本体41のシール手段45とのシール性の点からはフィルム61は薄い方が好ましい。この場合、フィルム61が吐出弁71の弁体としての機能を発揮し、キャップ本体41のシール手段45に密接する際に破損しないことが必要なことは言うまでもない。フィルム61の厚さの一例を示せば、内容物が醤油(一般的な醤油)のような比較的粘度の低い液体の場合、ポリエチレンフィルムで大凡20~30μm程度である。但し、この数値に限定されるものではない。
The film 61 is a thin film and includes a thin film having flexibility, flexibility and stretchability. The thickness of the film 61 is not particularly limited, and can be appropriately selected and used according to the application, contents, material, and the like. However, it is preferable that the film 61 is thin from the viewpoint of sealing performance between the upper surface of the film 61 and the base 51 and the sealing means 45 of the cap body 41. In this case, it is needless to say that the film 61 functions as a valve body of the discharge valve 71 and does not need to be damaged when contacting the sealing means 45 of the cap body 41. As an example of the thickness of the film 61, when the content is a liquid having a relatively low viscosity such as soy sauce (general soy sauce), it is about 20 to 30 μm with a polyethylene film. However, it is not limited to this value.
フィルム61の材質としては、ポリエチレンなどの合成樹脂製フィルムや、合成樹脂製のストレッチフィルム、この他、可撓性及び/又は柔軟性を有する薄膜の金属製フィルム、炭素製フィルム、ガラス製フィルム等が例示されるが、フィルム61は、特定の材質に限定されるものではなく、用途、内容物等に応じて適宜選択し使用することができる。例えば、フィルム61を通じて内容器11内に酸素が侵入しないようにするには、内容器11等と同様に、酸素遮断性、空気遮断性に優れるプラスチック、複合材、積層材その他材料を使用すればよい。また酸素遮断性と水蒸気遮断性とが同時に要求される場合には、空気の出入りを防ぐ合成樹脂材と水分の蒸発による乾燥を防ぐ合成樹脂材との多層フィルム、その他前記酸素遮断性と水蒸気遮断性とに優れるプラスチック、複合材、積層材等を好適に用いることができる。但し、フィルム61は、薄膜状であるため、内容器11等に比較して気体を透過し易いので、この点を考慮して材質を選定する必要がある。
As a material of the film 61, a synthetic resin film such as polyethylene, a synthetic resin stretch film, a thin metal film having flexibility and / or flexibility, a carbon film, a glass film, etc. However, the film 61 is not limited to a specific material, and can be appropriately selected and used according to the application, contents, and the like. For example, in order to prevent oxygen from entering the inner container 11 through the film 61, plastics, composite materials, laminated materials and other materials having excellent oxygen barrier properties and air barrier properties can be used as in the case of the inner container 11 and the like. Good. When oxygen barrier properties and water vapor barrier properties are required at the same time, a multilayer film of a synthetic resin material that prevents air from entering and exiting and a synthetic resin material that prevents drying due to evaporation of moisture, and other oxygen barrier properties and water vapor barrier properties. Plastics, composite materials, laminated materials, etc. that are excellent in properties can be suitably used. However, since the film 61 is in a thin film shape, it is easier for gas to pass through compared to the inner container 11 or the like, so it is necessary to select a material in consideration of this point.
フィルム61は、基台51と略同一の直径を有する弓形の部分円形状であり、基台51の上面に互いの円弧部分の外縁を合わせて弁孔52を覆うように重ねられる。
The film 61 has an arcuate partial circular shape having substantially the same diameter as the base 51, and is overlaid on the upper surface of the base 51 so as to cover the valve holes 52 with the outer edges of the respective arc portions aligned.
なおフィルム61の形状や配置は、特定のものに限定されるものではなく、弁孔52を覆い、かつ弁孔52を開閉自在に基台51の上面とキャップ41本体のシール手段45とに挟持される形状、配置であればよい。フィルム61としては、例えば、円形のフィルムに吐出孔を設けたもの(図示省略)を用いてもよく、このときには、吐出孔と弁孔52とが重ならないようにフィルム61が配置される。また後述する吐出口72を形成するフィルム61の直線状の一端は、例えば、波状に形成されていてもよく、縦に切り込み等が入っていてもよい。但し、フィルム61の形状は、吐出弁71の吐出性能及びシール性能を考慮して決められるべきである。
The shape and arrangement of the film 61 are not limited to a specific one, and the valve hole 52 is covered with the upper surface of the base 51 and the sealing means 45 of the main body of the cap 41 so that the valve hole 52 can be opened and closed. Any shape and arrangement may be used. As the film 61, for example, a circular film provided with discharge holes (not shown) may be used. At this time, the film 61 is arranged so that the discharge holes and the valve holes 52 do not overlap. Moreover, the linear one end of the film 61 which forms the discharge outlet 72 mentioned later may be formed in the wave shape, for example, and the cut | notch etc. may enter vertically. However, the shape of the film 61 should be determined in consideration of the discharge performance and the seal performance of the discharge valve 71.
次に本実施形態の注出容器1の逆止弁付キャップ40の製造方法について説明する。逆止弁付キャップ40の製造方法は、基台51を受台100に載置する載置工程S1、フィルム61を基台51の上面に重ねて密着させる密着工程S2、基台51をキャップ本体41に圧入する圧入工程S3からなる。
Next, a method for manufacturing the cap 40 with a check valve of the dispensing container 1 according to this embodiment will be described. The manufacturing method of the cap 40 with a check valve includes a mounting step S1 for mounting the base 51 on the receiving base 100, an adhesion step S2 in which the film 61 is stacked on the upper surface of the base 51, and the base 51 is attached to the cap body. It consists of press-fitting step S3 for press-fitting into 41.
載置工程S1では、基台51を受台100に載置する。受台100には、例えば、基台51のシール筒53が嵌り込む円筒体を使用することができる。このような受台100を使用すると基台51を安定して固定することができる。また受台100及び/又は基台51には、基台51の周方向の位置決めを行うために、例えば、それぞれに凹凸を設けたり、基台51の弁孔52の位置を中心からずらし、受台100に弁孔52に挿入するピン(図示省略)を設けたりするなどの位置決め手段を付加してもよい。
In the mounting step S1, the base 51 is mounted on the receiving base 100. For the cradle 100, for example, a cylindrical body into which the seal cylinder 53 of the base 51 is fitted can be used. When such a cradle 100 is used, the base 51 can be stably fixed. Further, in order to position the base 51 in the circumferential direction, the base 100 and / or the base 51 are provided with unevenness, for example, or the position of the valve hole 52 of the base 51 is shifted from the center. Positioning means such as providing a pin (not shown) to be inserted into the valve hole 52 in the base 100 may be added.
密着工程S2では、基台51の上面に円弧部の外縁を合わせてフィルム61を重ねる。このときフィルム61を基台51の上面に密着させる密着手段(図示省略)を用いることで、フィルム61の位置ずれ、皺や破れの発生を防止する。
In the adhesion step S2, the film 61 is overlaid on the upper surface of the base 51 with the outer edge of the arc portion aligned. At this time, by using a close contact means (not shown) for bringing the film 61 into close contact with the upper surface of the base 51, the film 61 is prevented from being displaced, wrinkled or torn.
密着手段を用いた密着方法としては、例えば、真空ポンプ(図示省略)等の吸引手段を用いて受台100の内側を負圧とし、基台51の弁孔52から吸引するようにしてフィルム61を基台51の上面に密着させる方法、基台51の上面及び/又はフィルム61に水等の液体を付着させフィルム61を基台51の上面に重ねる、液体の表面張力によりフィルム61を基台51の上面に密着させる方法、基台51の上面及び/又はフィルム61にコロナ放電等の帯電手段により静電気を帯電させ、フィルム61を基台51の上面に密着させる方法などを用いることができる。
As an adhesion method using the adhesion means, for example, the film 61 is configured such that the inside of the receiving base 100 is set to a negative pressure by using suction means such as a vacuum pump (not shown) and is sucked from the valve hole 52 of the base 51. The film 61 is made to adhere to the upper surface of the base 51 by attaching a liquid such as water to the upper surface of the base 51 and / or the film 61 and superimposing the film 61 on the upper surface of the base 51. A method of bringing the film 61 into close contact with the upper surface of the base 51 and / or a method of charging the static electricity to the upper surface of the base 51 and / or the film 61 by a charging means such as corona discharge and the film 61 being brought into close contact with the upper surface of the base 51 can be used.
圧入工程S3では、基台51の上からキャップ本体41を被せるように押し込み、基台51及びフィルム61の上面がキャップ本体41のシール手段45に密接するまで圧入する。
In the press-fitting step S3, the cap body 41 is pushed over the base 51 so that the upper surface of the base 51 and the film 61 is in close contact with the sealing means 45 of the cap body 41.
キャップ本体41を圧入すると、シール手段45にフィルム61の円弧周縁部が固定されるとともに、シール手段45に接触しないフィルム61の直線状の端部において吐出弁71の出口となる吐出口72が形成される。またフィルム61において、シール手段45よりも内側に位置する部分が吐出弁71の弁体となり、基台51の上面と剥離自在に密着する。
When the cap body 41 is press-fitted, the arc peripheral edge of the film 61 is fixed to the sealing means 45, and a discharge port 72 serving as the outlet of the discharge valve 71 is formed at the linear end of the film 61 that does not contact the sealing means 45. Is done. Further, in the film 61, a portion located inside the sealing means 45 becomes a valve body of the discharge valve 71, and is in close contact with the upper surface of the base 51 in a detachable manner.
なお圧入工程S3では、少なくともフィルム61がキャップ本体41のシール手段45に当接して固定されるまでキャップ本体41が圧入されていればよく、必ずしもシール手段45と基台51及びフィルム61の上面とのシール、及びシール手段45との接触部における基台51の上面とフィルム61とのシールが行われるまで密接していなくてもよい。この場合には、逆止弁付キャップ40がスパウト12に取付けられたときに、基台51がスパウト12の口部13により押し込まれることで、シール手段45と基台51及びフィルム61の上面とが密接し、シール手段45と基台51及びフィルム61の上面とのシール、及びシール手段45との接触部における基台51の上面とフィルム61とのシールが行われる。
In the press-fitting step S3, it is sufficient that the cap main body 41 is press-fitted until at least the film 61 is fixed in contact with the sealing means 45 of the cap main body 41. The sealing means 45, the base 51, and the upper surface of the film 61 are not necessarily required. And the upper surface of the base 51 at the contact portion with the sealing means 45 and the film 61 need not be in close contact with each other. In this case, when the cap 40 with a check valve is attached to the spout 12, the base 51 is pushed by the mouth portion 13 of the spout 12, so that the sealing means 45, the base 51 and the upper surface of the film 61 are , The sealing means 45 is sealed with the base 51 and the upper surface of the film 61, and the upper surface of the base 51 and the film 61 are sealed at the contact portion with the sealing means 45.
内容物が液体の場合、シール手段45と基台51及びフィルム61の上面とのシール性、及びシール手段45との接触部における基台51とフィルム61とのシール性は、少なくとも液密であれば内容器11と外容器21との間の空間部20への内容物の漏出を防止することができる。内容器11への外気の侵入は、後述するように内容器11内の負圧による作用と、基台51の上面とフィルム61との隙間に介在する内容物の毛管吸引力とによる基台51の上面へのフィルム61の密着により防止される。なお内容物が気体の場合は、気密性が要求される。
When the contents are liquid, the sealing performance between the sealing means 45, the base 51 and the upper surface of the film 61, and the sealing performance between the base 51 and the film 61 at the contact portion with the sealing means 45 should be at least liquid-tight. For example, the leakage of the contents to the space 20 between the inner container 11 and the outer container 21 can be prevented. The intrusion of outside air into the inner container 11 is caused by the action of negative pressure in the inner container 11 and the base 51 due to the capillary suction force of the contents interposed in the gap between the upper surface of the base 51 and the film 61 as described later. This is prevented by the adhesion of the film 61 to the upper surface. In addition, when the contents are gas, airtightness is required.
上記の製造方法は、好ましい一例であって、逆止弁付キャップ40の製造方法は、特定の方法に限定されるものではない。ただし逆止弁付キャップ40の吐出弁71が正常に逆止機能を発揮するためには、少なくとも逆止弁付キャップ40がスパウト12に取付けられたときに、フィルム61に皺や破れが発生することなくシール手段45と基台51及びフィルム61の上面とが密接し、シール手段45と基台51及びフィルム61の上面とのシール、及びシール手段45との接触部における基台51の上面とフィルム61とのシールが行われ、フィルム61の弁体部分が基台51の上面に剥離自在に密着する製造方法を用いるべきである。
The above manufacturing method is a preferred example, and the manufacturing method of the check valve cap 40 is not limited to a specific method. However, in order for the discharge valve 71 of the cap 40 with a check valve to normally exhibit a check function, at least when the cap 40 with a check valve is attached to the spout 12, the film 61 is wrinkled or torn. The sealing means 45, the base 51 and the upper surface of the film 61 are in close contact, the seal between the sealing means 45, the base 51 and the upper surface of the film 61, and the upper surface of the base 51 at the contact portion with the sealing means 45 A manufacturing method in which sealing with the film 61 is performed and the valve body portion of the film 61 is in close contact with the upper surface of the base 51 in a peelable manner should be used.
なお本発明において、吐出弁71が形成されている状態とは、上記のように、キャップ本体41に基台51とフィルム61とを取付けた段階で、シール手段45と基台51及びフィルム61の上面とのシール、及びシール手段45との接触部における基台51の上面とフィルム61とのシールが行われ、吐出弁71が逆止機能を正常に発揮する状態に限定されず、逆止弁付キャップ40がスパウト12(容器本体に口部)に取付けられたときに、これらのシールが行われ、吐出弁71が逆止機能を正常に発揮する状態を含む。
In the present invention, the state in which the discharge valve 71 is formed means that the sealing means 45, the base 51, and the film 61 are in the stage where the base 51 and the film 61 are attached to the cap body 41 as described above. The seal between the upper surface and the upper surface of the base 51 at the contact portion with the sealing means 45 and the film 61 are sealed, and the discharge valve 71 is not limited to a state in which the check function is normally exhibited. When the attached cap 40 is attached to the spout 12 (the mouth of the container main body), these seals are performed, and the discharge valve 71 normally includes a state in which the check function is exhibited.
注出容器1は、内容器11に内容物を充填し、内容器11を外容器21に収容し、スパウト12の上フランジ15に吸気弁体フィルム38を載置してリングキャップ31を外容器21に螺合し、その後、逆止弁付キャップ40をスパウト12に螺合させて製造される。なお注出容器1の製造方法は、これに限定されるものではなく、例えば、内容物の充填は、適宜、最適なタイミングで行えばよい。
In the dispensing container 1, the inner container 11 is filled with the contents, the inner container 11 is accommodated in the outer container 21, the intake valve body film 38 is placed on the upper flange 15 of the spout 12, and the ring cap 31 is placed in the outer container. Then, the cap 40 with a check valve is screwed onto the spout 12. In addition, the manufacturing method of the extraction container 1 is not limited to this, For example, what is necessary is just to perform filling of the content at the optimal timing suitably.
なお逆止弁付キャップ40及びスパウト12には、一度、螺合させると容易に取外せないように互いに係止する係止爪(図示省略)を設けておいてもよい。逆止弁付キャップ40とスパウト12とを容易に取外せないようにすることで、使用中の取外しによる内容物の酸化や、第三者による異物の混入等を防止することができる。
The cap 40 with check valve and the spout 12 may be provided with locking claws (not shown) that are locked together so that they cannot be easily removed once screwed together. By preventing the cap 40 with the check valve and the spout 12 from being easily removed, it is possible to prevent the contents from being oxidized due to the removal during use or the entry of foreign substances by a third party.
また注出容器1は、内容物を注出し切った後に内容器11のみを内容物が充填された新しいものに詰め替えることで、外容器21、リングキャップ31、吸気弁体フィルム38、逆止弁付キャップ40を繰返し使用することができる。この場合、スパウト12の口部13に薄膜状の封止材(図示省略)を接着して口部13を封止しておき、逆止弁キャップ40のシール筒53で封止材を破断して開封するようにしておくと、詰め替え時の内容物の酸化を防止することができる。
In addition, the dispensing container 1 is provided with an outer container 21, a ring cap 31, an intake valve body film 38, and a check valve by refilling only the inner container 11 with a new one filled with the contents after the contents are completely poured out. The cap 40 can be used repeatedly. In this case, a thin film-like sealing material (not shown) is adhered to the mouth portion 13 of the spout 12 to seal the mouth portion 13, and the sealing material is broken by the seal cylinder 53 of the check valve cap 40. By opening the package, the contents can be prevented from being oxidized during refilling.
なお封止材等を用いずに詰め替え時の内容物の酸化を防止する方法としては、内容器11、リングキャップ31、吸気弁体フィルム38、及び逆止弁付キャップ40を組み付けた状態のものを外容器21に詰め替える方法を用いることもできる。この他、繰返し使用するもの及び詰め替えるものの選定は、用途等に合わせて適宜決めればよい。
In addition, as a method for preventing the oxidation of the contents at the time of refilling without using a sealant or the like, the inner container 11, the ring cap 31, the intake valve body film 38, and the check valve cap 40 are assembled. It is also possible to use a method of refilling the outer container 21. In addition, the selection of what is repeatedly used and what is to be refilled may be appropriately determined according to the application.
次に内容物を醤油とし、注出容器1を酸化防止用の醤油差しとして使用する場合を例として、使用方法を例示する。逆止弁付キャップ40をスパウト12に取付けた後は、蓋体49を開き、注出容器1を上向きとしたまま外容器21を押圧して収縮させる。外容器21を収縮させると外容器21と内容器11との間の空間部20が加圧されて吸気弁75が閉じ、内容器11が加圧され収縮する。内容器11が収縮するとフィルム61が浮き上がって吐出弁71が開き、内容器11内に残存する空気又はガスが排出される。これにより内容器11内は醤油で満たされ、吐出弁71により空気の侵入が防止されるので、醤油が酸化することはない。
Next, the method of use will be illustrated by taking as an example the case where the contents are soy sauce and the dispensing container 1 is used as a soy sauce bottle for antioxidant. After attaching the cap 40 with a check valve to the spout 12, the lid 49 is opened, and the outer container 21 is pressed and contracted with the dispensing container 1 facing upward. When the outer container 21 is contracted, the space 20 between the outer container 21 and the inner container 11 is pressurized, the intake valve 75 is closed, and the inner container 11 is pressurized and contracted. When the inner container 11 contracts, the film 61 rises and the discharge valve 71 opens, and the air or gas remaining in the inner container 11 is discharged. Thereby, the inside of the inner container 11 is filled with soy sauce, and air is prevented from entering by the discharge valve 71, so that the soy sauce is not oxidized.
醤油を注出するときは、注出容器1を下向きに傾けて外容器21を押圧して収縮させると、内容器11が収縮し弁孔52から吐出弁71へ醤油が流れ込み、フィルム61が浮き上がって吐出弁71が開弁し、醤油が吐出口72から吐出されて注出口42から注がれる。
When pouring out the soy sauce, when the pouring container 1 is tilted downward and the outer container 21 is pressed and contracted, the inner container 11 contracts and the soy sauce flows into the discharge valve 71 from the valve hole 52, and the film 61 rises. Then, the discharge valve 71 is opened, soy sauce is discharged from the discharge port 72 and poured from the spout 42.
外容器21の収縮を止めて注出容器1を上向きに戻すと、内容器11内の負圧による作用と、基台51の上面とフィルム61との隙間に介在する醤油の毛管吸引力とによりフィルム61が基台51の上面に素早く密着して吐出弁71が閉弁される。このため閉弁後、内容器11内に空気が入り込むことはない。また外容器21の形状復元性により、外容器21と内容器11との間の空間部20が負圧となり、吸気弁75が開弁して外容器21と内容器11との間の空間部20に外気が流入し、外容器21が元の形状に戻る。
When the contraction of the outer container 21 is stopped and the dispensing container 1 is returned upward, due to the negative pressure in the inner container 11 and the capillary suction force of soy sauce interposed in the gap between the upper surface of the base 51 and the film 61 The film 61 quickly comes into close contact with the upper surface of the base 51 and the discharge valve 71 is closed. For this reason, air does not enter the inner container 11 after the valve is closed. Further, due to the shape recoverability of the outer container 21, the space 20 between the outer container 21 and the inner container 11 becomes negative pressure, the intake valve 75 is opened, and the space between the outer container 21 and the inner container 11 is opened. Outside air flows into 20 and the outer container 21 returns to its original shape.
以上のように本実施形態の注出容器1の逆止弁付キャップ40は、基台51の上面にフィルム61を重ねて基台51をキャップ本体41に取付けて構成されているので、製造が容易である。このため本実施形態で用いた容器本体に限らず、例えば、市販されている容器本体に使用する際には、該容器本体の口部の形状に合わせてキャップ本体41の筒部の形状を変更すれば、そのままの構成で市販の容器本体を何ら改造することなく適用することができるため、利便性に優れる。
As described above, the cap 40 with a check valve of the dispensing container 1 of the present embodiment is configured by attaching the base 51 to the cap body 41 with the film 61 overlapped on the upper surface of the base 51. Easy. For this reason, not only the container body used in the present embodiment but also, for example, when used for a commercially available container body, the shape of the cylindrical portion of the cap body 41 is changed in accordance with the shape of the mouth of the container body. By doing so, it is possible to apply a commercially available container body with no modification, so that it is excellent in convenience.
なお本実施形態の注出容器1では、逆止弁付キャップ40とスパウト12との連結に螺合を用いたが、これに限定されるものではなく、スナップフィット等を用いた嵌合や、圧入、接着等の方法で逆止弁付キャップ40とスパウト12との連結を行うことも可能である。外容器21とリングキャップ31との連結についても同様である。
In addition, in the pouring container 1 of the present embodiment, screwing is used for the connection between the cap 40 with the check valve and the spout 12, but this is not a limitation, and fitting using a snap fit or the like, It is also possible to connect the cap 40 with a check valve and the spout 12 by a method such as press fitting or adhesion. The same applies to the connection between the outer container 21 and the ring cap 31.
またキャップ本体41と基台51との取付方法も、圧入に限定されるものではなく、例えば、後述する第3実施形態の逆止弁付キャップ101、第4実施形態の逆止弁付キャップ111のように、係止手段103を用いて係止させる方法や、螺合させる方法、接着等を用いることができる。
Also, the method of attaching the cap body 41 and the base 51 is not limited to press-fitting. For example, the cap 101 with a check valve according to a third embodiment to be described later, and the cap 111 with a check valve according to a fourth embodiment. As described above, a method of locking using the locking means 103, a method of screwing, bonding, or the like can be used.
またスパウト12の口部13は、逆止弁付キャップ40のシール筒53によりシールされるので、図5に示すように、必ずしも基台51の下面に当接していなくてもよい。
Further, since the mouth portion 13 of the spout 12 is sealed by the seal cylinder 53 of the cap 40 with a check valve, it does not necessarily have to be in contact with the lower surface of the base 51 as shown in FIG.
図6は、本発明の第2実施形態の注出容器2の構成を示す斜視図である。図7は、図6のキャップ本体82の斜視図である。図8は、図6の基台83の斜視図である。図9は、図6の注出容器2の要部断面図である。図1及び図2に示す第1実施形態の注出容器1と同一の構成には同一の符号を付して説明を省略する。なお図9では、内容器11のフィルム体18を省略している。
FIG. 6 is a perspective view showing the configuration of the dispensing container 2 of the second embodiment of the present invention. FIG. 7 is a perspective view of the cap body 82 of FIG. FIG. 8 is a perspective view of the base 83 of FIG. FIG. 9 is a cross-sectional view of a main part of the dispensing container 2 of FIG. The same components as those of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. In FIG. 9, the film body 18 of the inner container 11 is omitted.
本実施形態の注出容器2は、第1実施形態の注出容器1と基本的構成は同じであるが、フィルム61が吐出弁71の弁体と吸気弁75の弁体とを兼ねる。これに伴い注出容器2は、リングキャップ81、キャップ本体82、及び基台83の構造が第1実施形態の注出容器1のものと異なり、吸気弁体フィルム38を有しない。また本実施形態の注出容器2では、リングキャップ81とキャップ本体82とが連結されている。
The dispensing container 2 of the present embodiment has the same basic configuration as the dispensing container 1 of the first embodiment, but the film 61 serves as both the valve body of the discharge valve 71 and the valve body of the intake valve 75. Accordingly, the extraction container 2 is different from that of the extraction container 1 of the first embodiment in the structure of the ring cap 81, the cap body 82, and the base 83, and does not have the intake valve body film 38. Moreover, in the extraction container 2 of this embodiment, the ring cap 81 and the cap main body 82 are connected.
リングキャップ81は、挿通孔32の外縁部が隆起してキャップ本体82の下端部と連結する連結部91が形成されており、連結部91の内周面に後述するキャップ本体82の嵌合凸部94を嵌合させる嵌合溝92が形成されている。またリングキャップ81は、吸気路を有していない。但し、リングキャップ81に吸気路(図示省略)を設け、吸気路を開閉する吸気弁体フィルム(図示省略)を備える注出容器(図示省略)を構成することも可能である。
The ring cap 81 is formed with a connecting portion 91 that protrudes from the outer edge portion of the insertion hole 32 and is connected to the lower end portion of the cap main body 82.

However, it is also possible to form an extraction container (not shown) provided with an intake passage (not shown) in the ring cap 81 and provided with an intake valve element film (not shown) for opening and closing the intake passage.
キャップ本体82は、頂部の一部に穿設され吸気弁75の入口となる吸気孔93を備え、筒部外周面の下端部にリングキャップ81の嵌合溝92に嵌合する嵌合凸部94を備え、筒部内周面の一部に上下方向に亘って一定の幅で基台83の周方向の位置決め手段となる位置決め溝95を備える。位置決め溝95は、吸気孔93から外容器21と内容器11との間の空間部20に外気を導入する際の吸気路を兼ねる。さらに位置決め溝95の位置は、キャップ本体82の注出口42と基台83の弁孔52とが中心を挟んで互いに反対側に配置されるように決められていることが好ましい。
The cap body 82 includes an intake hole 93 that is formed in a part of the top portion and serves as an inlet of the intake valve 75, and a fitting convex portion that fits into the fitting groove 92 of the ring cap 81 at the lower end portion of the outer peripheral surface of the cylindrical portion. 94, and a positioning groove 95 serving as a positioning means in the circumferential direction of the base 83 with a certain width in the vertical direction is provided in a part of the inner peripheral surface of the cylindrical portion. The positioning groove 95 also serves as an intake path for introducing outside air from the intake hole 93 to the space 20 between the outer container 21 and the inner container 11. Furthermore, the position of the positioning groove 95 is preferably determined so that the spout 42 of the cap body 82 and the valve hole 52 of the base 83 are arranged on the opposite sides with respect to the center.
吸気孔93は、外容器21と内容器11との間の空間部20に外気を導入すべく、平面視においてシール手段45よりも外側に配置される。なお吸気孔93の形状や数は、特定のものに限定されるものではなく、例えば、後述する第11実施形態の逆止弁付キャップ181のように複数箇所に設けられていてもよい。
The air intake hole 93 is disposed outside the sealing means 45 in a plan view so as to introduce outside air into the space 20 between the outer container 21 and the inner container 11. The shape and the number of the intake holes 93 are not limited to a specific one, and may be provided at a plurality of locations, for example, like a cap 181 with a check valve according to an eleventh embodiment described later.
基台83は、上面に段差96が形成されており、外周面にキャップ本体82の位置決め溝95に嵌り込む位置決め片97が形成されている。位置決め片97の形状は、特定の形状に限定されるものではないが、外容器21と内容器11との間の空間部20に外気を導入可能に、キャップ本体82の位置決め溝95を閉塞しない形状である必要がある。
The base 83 has a step 96 formed on the upper surface, and a positioning piece 97 that fits into the positioning groove 95 of the cap body 82 is formed on the outer peripheral surface. The shape of the positioning piece 97 is not limited to a specific shape, but the positioning groove 95 of the cap body 82 is not closed so that outside air can be introduced into the space 20 between the outer container 21 and the inner container 11. It needs to be in shape.
本実施形態の注出容器2の逆止弁付キャップ80では、フィルム61を基台83の上面に重ねると、基台83の上面に段差96を形成したことによりフィルム61の周縁部が基台83の上面に接することなく上下動自在に浮いた状態となる。本実施形態の注出容器2では、フィルム61において、基台83の上面に接する部分が吐出弁71の弁体となる吐出弁体部62となり、基台83の上面に接しない周縁部の一部が吸気弁75の弁体となる吸気弁体部63となる。
In the cap 80 with a check valve of the dispensing container 2 of the present embodiment, when the film 61 is overlaid on the upper surface of the base 83, the stepped portion 96 is formed on the upper surface of the base 83, so that the peripheral edge of the film 61 is the base. It will be in the state which floated freely without touching the upper surface of 83. In the dispensing container 2 of the present embodiment, the portion of the film 61 that contacts the upper surface of the base 83 becomes the discharge valve body portion 62 that serves as the valve body of the discharge valve 71, and one peripheral portion that does not contact the upper surface of the base 83. The portion serves as an intake valve body 63 that serves as a valve body of the intake valve 75.
フィルム61を重ねた基台83をキャップ本体82に圧入すると、フィルム61がキャップ本体82のシール手段45に押えられ第1実施形態の注出容器1の逆止弁付キャップ40と同様、吐出弁71が形成されるとともに、フィルム61の吸気弁体部63がキャップ本体82の吸気孔93を開閉自在に覆い、吸気弁75が形成される。なお本実施形態の注出容器2の逆止弁付キャップ80の製造方法は、第1実施形態の注出容器1の逆止弁付キャップ40と同様であるため説明を省略する。
When the base 83 on which the film 61 is stacked is press-fitted into the cap main body 82, the film 61 is pressed by the sealing means 45 of the cap main body 82, and the discharge valve is similar to the check valve cap 40 of the dispensing container 1 of the first embodiment. 71 is formed, and the intake valve body 63 of the film 61 covers the intake hole 93 of the cap body 82 so as to be openable and closable, thereby forming the intake valve 75. In addition, since the manufacturing method of the cap 80 with a non-return valve of the extraction container 2 of this embodiment is the same as that of the cap 40 with a non-return valve of the extraction container 1 of 1st Embodiment, description is abbreviate | omitted.
逆止弁付キャップ80を内容器11のスパウト12の口部13に取付け、リングキャップ81に連結し、リングキャップ81に外容器21を取付けると、吸気孔93から外容器21と内容器11との間の空間部20への外気の流路が形成される。
When the cap 80 with a check valve is attached to the mouth portion 13 of the spout 12 of the inner container 11, is connected to the ring cap 81, and the outer container 21 is attached to the ring cap 81, the outer container 21 and the inner container 11 are A flow path of outside air to the space portion 20 is formed.
以上のように、本実施形態の注出容器2では、フィルム61が吐出弁71及び吸気弁75の弁体を兼ねるので、吸気弁体フィルム38を使用する場合や、吸気弁75として他の逆止弁を使用する場合に比べて、材料コスト及び製造コストを低減することができる。また逆止弁キャップ80に吐出弁71及び吸気弁75の両方を設けるので、例えば、容器本体として市販されている既存の容器等を用いる場合に、容器本体に吸気孔(吸気路)や吸気弁を新たに設ける必要がない。
As described above, in the dispensing container 2 of the present embodiment, since the film 61 also serves as the valve body of the discharge valve 71 and the intake valve 75, when the intake valve body film 38 is used, or as the intake valve 75, the other reverse Compared with the case where a stop valve is used, material cost and manufacturing cost can be reduced. In addition, since both the discharge valve 71 and the intake valve 75 are provided in the check valve cap 80, for example, when using an existing container that is commercially available as a container body, an intake hole (intake passage) or an intake valve is provided in the container body. There is no need to provide a new one.
なおリングキャップ81とキャップ本体82との連結方法は、特定の方法に限定されるものではなく、例えば、ネジやスナップフィット等を用いた方法や接着等を採用してもよい。
In addition, the connection method of the ring cap 81 and the cap main body 82 is not limited to a specific method, For example, you may employ | adopt the method using a screw | thread, a snap fit, etc., adhesion | attachment, etc.

Also, the method for connecting the outer container 21 and the ring cap 31, the method for connecting the spout 12 and the cap 80 with check valve, and the method for attaching the cap body 82 and the base 83 are also the dispensing container 1 of the first embodiment. Similarly to the above, it is not limited to a specific method.
キャップ本体82と基台83との位置決め方法も、特定の方法に限定されるものではなく、例えば、後述する第6実施形態の逆止弁付キャップ131や第7実施形態の逆止弁付キャップ141で用いる方法等でもよい。
The positioning method of the cap body 82 and the base 83 is not limited to a specific method. For example, the cap 131 with a check valve according to a sixth embodiment and the cap with a check valve according to a seventh embodiment which will be described later. 141 may be used.
また本実施形態の注出容器2においても、第1実施形態の注出容器1と同様、内容物を注出し切った後には、内容器11のみ、又は内容器11と他の部材とを予め連結したものを外容器21に詰め替えて使用することができる。
Also in the dispensing container 2 of the present embodiment, as with the dispensing container 1 of the first embodiment, after the content has been completely poured out, only the inner container 11 or the inner container 11 and another member are connected in advance. It is possible to refill the outer container 21 for use.
図10は、本発明の第3実施形態の逆止弁付キャップ101の断面図である。図1及び図2に示す第1実施形態の注出容器1の逆止弁付キャップ40と同一の構成には同一の符号を付して説明を省略する。本実施形態の逆止弁付キャップ101は、第1実施形態の注出容器1の逆止弁付キャップ40と基本的構成は同じであるが、キャップ本体102に基台51を係止させる係止手段103を備える。
FIG. 10 is a cross-sectional view of a cap 101 with a check valve according to a third embodiment of the present invention. The same components as those of the cap 40 with a check valve of the dispensing container 1 of the first embodiment shown in FIG. 1 and FIG. The cap 101 with a check valve of the present embodiment has the same basic configuration as the cap 40 with a check valve of the dispensing container 1 of the first embodiment, but is a mechanism for locking the base 51 to the cap body 102. Stop means 103 is provided.
キャップ本体102の筒部内周面には、シール手段45から基台51の厚み分、下がった位置に爪状の係止手段103が全周に亘って形成されている。係止手段103は、基台51をキャップ本体102に取付ける際に、基台51を誘い込むべく、上部の方へ徐々に肉厚になるように傾斜して形成されており、上端面104において基台51の下面と密接する。なお係止手段103は、全周に亘って連続的に形成されているものに限定されるものではなく、部分的に形成されていてもよい。
On the inner peripheral surface of the cylinder portion of the cap body 102, a claw-like locking means 103 is formed over the entire circumference at a position lowered from the sealing means 45 by the thickness of the base 51. When the base 51 is attached to the cap main body 102, the locking means 103 is formed so as to be gradually inclined toward the upper part so that the base 51 can be guided. Close contact with the lower surface of the base 51. The locking means 103 is not limited to being formed continuously over the entire circumference, and may be formed partially.
基台51をキャップ本体102に取付ける際には、基台51の外周面が係止手段103を乗り越えるまで押し込み、基台51の下面が係止手段103の上端面104に密接して係止する。このとき基台51及びフィルム61の上面がシール手段45にしっかりと密接してシールされるように基台51の厚みを考慮して係止手段103の形成位置を決めておくことが好ましいが、逆止弁付キャップ101を容器本体の口部に取付けたときに基台51が押し込まれることでシールが可能であれば、フィルム61が固定される程度でもよい。
When the base 51 is attached to the cap body 102, the base 51 is pushed in until the outer peripheral surface of the base 51 gets over the locking means 103, and the lower surface of the base 51 is closely locked to the upper end surface 104 of the locking means 103. . At this time, it is preferable to determine the formation position of the locking means 103 in consideration of the thickness of the base 51 so that the upper surfaces of the base 51 and the film 61 are tightly sealed to the sealing means 45. If the base 51 is pushed in when the cap 101 with a check valve is attached to the mouth of the container body and sealing is possible, the film 61 may be fixed.
また基台51の外周面が係止手段103を乗り越える際に、係止手段103とフィルム61とが接触してフィルム61に不均一に張力が加わり皺や破れが発生しないように、係止手段103及び基台51の上面周縁部の形状を決めておく必要がある。例えば、基台51の上面の縁に係止手段103の上端面104の厚み分、面取りを施し、面取りを施した後の基台51の上面と略同一の直径のフィルム61を重ねた基台51をキャップ本体102に取付けることで係止手段103とフィルム61との接触を回避することができる。
Also, when the outer peripheral surface of the base 51 gets over the locking means 103, the locking means 103 and the film 61 come into contact with each other, so that the film 61 is not uniformly tensioned and wrinkles or tears are not generated. 103 and the shape of the periphery of the upper surface of the base 51 need to be determined. For example, the base 51 is chamfered on the edge of the upper surface of the base 51 by the thickness of the upper end surface 104 of the locking means 103 and the film 61 having the same diameter as that of the upper surface of the base 51 after chamfering is overlapped. By attaching 51 to the cap body 102, contact between the locking means 103 and the film 61 can be avoided.
図11は、本発明の第4実施形態の逆止弁付キャップ111の断面図である。図1及び図2に示す第1実施形態の注出容器1の逆止弁付キャップ40と同一の構成には同一の符号を付して説明を省略する。本実施形態の逆止弁付キャップ111は、第1実施形態の注出容器1の逆止弁付キャップ40と基本的構成は同じであるが、キャップ本体112及び基台113に互いに螺合する雌ネジ114及び雄ネジ115を備える。
FIG. 11 is a cross-sectional view of a cap 111 with a check valve according to a fourth embodiment of the present invention.

The cap 121 with a check valve of this embodiment includes a seal cylinder 125 that seals the mouth of the container body in the cap body 122, and the base 123 in a state where a ring member 124 that is press-fitted into the seal cylinder 125 is interposed. It is configured to be press-fitted into the inner peripheral surface of the seal cylinder 125.
リング部材124は、外径がキャップ本体122のシール筒125の内径と略同一であり、上面及び下面に全周に亘って形成された凸状のシール手段126、127を備え、上面のシール手段126がキャップ本体122の天井面43に密着するように、キャップ本体122のシール筒125に圧入される。リング部材124の材質は、基台123等と同様であるため説明を省略する。
The ring member 124 has an outer diameter that is substantially the same as the inner diameter of the seal cylinder 125 of the cap body 122, and includes convex sealing means 126, 127 formed on the upper surface and the lower surface over the entire circumference. It is press-fitted into the seal cylinder 125 of the cap body 122 so that 126 is in close contact with the ceiling surface 43 of the cap body 122. Since the material of the ring member 124 is the same as that of the base 123 and the like, description thereof is omitted.
なおリング部材124の上面及び下面がキャップ本体122の天井面43及び基台51及びフィルム61の上面に密接してシールを行うことが可能であれば、シール手段126、127を設けなくてもよい。またリング部材124としては、ガスケット等を用いることもできる。
If the upper and lower surfaces of the ring member 124 can be in close contact with the ceiling surface 43, the base 51 and the upper surface of the film 61 of the cap body 122, the sealing means 126 and 127 need not be provided. . As the ring member 124, a gasket or the like can be used.
基台123は、リング部材124の下面のシール手段127に基台123及びフィルム61の上面が密接してシールされるように、リング部材124が圧入されたキャップ本体122のシール筒125に圧入される。
The base 123 is press-fitted into the seal cylinder 125 of the cap body 122 into which the ring member 124 is press-fitted so that the base 123 and the upper surface of the film 61 are tightly sealed with the sealing means 127 on the lower surface of the ring member 124. The
本実施形態の逆止弁付キャップ121のようにリング部材124を用いることで、キャップ本体が押え面を有しない場合でも、吐出弁71の開弁代を確保することが可能である。本実施形態に記載した以外でも、例えば、第1実施形態の注出容器1の逆止弁付キャップ40において、押え面44を有しないキャップ本体(図示省略)を用いる場合、リング部材124を介して吐出弁71を形成することができる。
By using the ring member 124 like the cap 121 with the check valve of the present embodiment, it is possible to secure the opening allowance of the discharge valve 71 even when the cap body does not have a pressing surface. In addition to those described in the present embodiment, for example, in the case of using a cap body (not shown) having no pressing surface 44 in the cap 40 with a check valve of the dispensing container 1 of the first embodiment, the ring member 124 is used. Thus, the discharge valve 71 can be formed.
なおリング部材124のシール筒125への取付方法は、圧入に限定されるものではなく、前述した実施形態における基台のキャップ本体への取付方法と同様、係止、螺合、スナップフィット等を用いた嵌合、接着等でもよい。基台123のシール筒125への取付方法についても同様である。また基台123は、シール筒125ではなく、リング部材124に圧入、係止、螺合、嵌合、又は接着等で取付けることも可能である。

FIG. 18 is a cross-sectional view of a cap 171 with a check valve according to the tenth embodiment of the present invention. The same components as those of the cap with check valve 161 of the ninth embodiment shown in FIGS. 16 and 17 are denoted by the same reference numerals and description thereof is omitted. The cap 171 with check valve of the present embodiment has the same basic configuration as the cap 161 with check valve of the ninth embodiment, but the shape and mounting procedure of the intake valve element film 174 are different.
キャップ本体172は、吸気孔93の近傍の筒部内周面に吸気弁体フィルム174を支持する支持片175を備える。支持片175は、支持片175の上面とキャップ本体172の押え面44との間に吸気弁体フィルム174を取付け可能に配置される。
The cap body 172 includes a support piece 175 that supports the intake valve element film 174 on the inner peripheral surface of the cylindrical portion in the vicinity of the intake hole 93.

以上、第1から第11実施形態の注出容器1、2、及び逆止弁付キャップ40、80、101、111、121、131、141、151、161、171、181を用いて、本発明の逆止弁付キャップ、該逆止弁付キャップを備える注出容器及び該逆止弁付キャップの製造方法を説明したが、本発明の逆止弁付キャップ、該逆止弁付キャップを備える注出容器及び該逆止弁付キャップの製造方法は、上記実施形態に限定されるものではなく、要旨を変更しない範囲で変形して使用することができる。
As described above, the present invention using the dispensing containers 1 and 2 and the caps 40, 80, 101, 111, 121, 131, 141, 151, 161, 171, 181 with check valves of the first to eleventh embodiments. The check valve cap, the dispensing container including the check valve cap, and the manufacturing method of the check valve cap have been described. However, the check valve cap of the present invention and the check valve cap are provided. The manufacturing method of the extraction container and the cap with the check valve is not limited to the above embodiment, and can be used by being modified without changing the gist.
基台には、主に平板材を用いたが、これに限定されるものではなく、基台の上面及び下面には、凹凸等が設けられていてもよい。また基台は、平坦である必要はなく、キャップ本体のシール手段45と気密に接することが可能であれば凹凸等が設けられていてもよい。
Although a flat plate material is mainly used for the base, the invention is not limited to this, and irregularities or the like may be provided on the upper surface and the lower surface of the base. The base does not need to be flat, and may be provided with irregularities or the like as long as it can be in airtight contact with the sealing means 45 of the cap body.
基台をキャップ本体に取付けたときに、フィルム61に均一に張力が加わる構造とすることで、フィルム61と基台の上面との密着性を高め、吐出弁71のシール性能を高めることもできる。例えば、基台の上面をドーム状に形成すると、フィルム61に均一に張力を加えやすくなり、かつ張力がフィルム61を基台に密着させる方向にも働くので、吐出弁71のシール性能が向上し、好ましい。このような構造については、例えば、本件出願人が出願した特願2013-100316号に記載の図4、図6、図7に示される注出キャップを参考にすることができる。
When the base is attached to the cap body, the film 61 has a structure in which tension is uniformly applied, so that the adhesion between the film 61 and the upper surface of the base can be improved and the sealing performance of the discharge valve 71 can be improved. . For example, when the upper surface of the base is formed in a dome shape, it is easy to apply a uniform tension to the film 61, and the tension also works in the direction in which the film 61 is in close contact with the base, so that the sealing performance of the discharge valve 71 is improved. ,preferable. For such a structure, for example, the extraction cap shown in FIGS. 4, 6, and 7 described in Japanese Patent Application No. 2013-100316 filed by the present applicant can be referred to.
基台の弁座には、例えば、本件出願人が出願した国際出願番号PCT/JP2013/83871に記載の図31及び図32に示される逆止弁ユニットのように、毛管吸引力を確実に働かせるための葉脈状の溝や全幅に亘って設けられる溝などが形成されていてもよい。このような溝を設けることで吐出弁71のシール性能を向上させることができる。なお溝の深さは、液体が常に滞留する深さで、かつ液体の入換えが円滑に行われる深さに適宜決められる。溝が深すぎると液体の入換えが円滑に行われなくなるため必要以上に深くすべきではない。
For example, a capillary suction force is applied to the valve seat of the base as in the check valve unit shown in FIGS. 31 and 32 described in International Application No. PCT / JP2013 / 83871 filed by the present applicant. For this purpose, a vein-like groove or a groove provided over the entire width may be formed. By providing such a groove, the sealing performance of the discharge valve 71 can be improved. The depth of the groove is appropriately determined to be a depth at which the liquid always stays and a depth at which the liquid can be exchanged smoothly. If the groove is too deep, the liquid cannot be exchanged smoothly and should not be deeper than necessary.
また基台の弁座に設けられる溝の形状は、特定の形状に限定されるものではなく、例えば丸印や×印等の溝を設けてもよい。また溝ではなく、表面を荒らす、又は表面に小さな凹凸を設けることで同様の効果を得ることもできる。
Also, the shape of the groove provided in the valve seat of the base is not limited to a specific shape, and for example, a groove such as a round mark or an X mark may be provided. Further, the same effect can be obtained by roughening the surface instead of the groove or providing small irregularities on the surface.
キャップ本体への基台の取付方法は、圧入、係止、螺合に限定されるものではなく、例えば、基台の上面とキャップ本体の押え面とを振動溶着又は超音波溶着等を用いて接着してもよい。少なくとも、フィルムに皺や破れが発生せず、フィルムが弁孔を開閉自在に基台の上面に密着するような方法であれば製造コスト等を考慮して適宜、最適な方法を採用すればよい。
The mounting method of the base to the cap body is not limited to press-fitting, locking, and screwing. For example, the upper surface of the base and the pressing surface of the cap body are used by vibration welding or ultrasonic welding. It may be glued. As long as the film does not cause wrinkles or tears and the film is in close contact with the upper surface of the base so that the valve hole can be opened and closed, an optimum method may be adopted as appropriate in consideration of manufacturing costs and the like. .
また本発明において、吐出弁(及び吸気弁)が形成されている状態とは、基台とフィルムとをキャップ本体に取付けたときに、基台及びフィルムの上面とキャップ本体(シール手段)との接触部のシール、及び該接触部における基台の上面とフィルムとのシールが行われ、吐出弁(及び吸気弁)が逆止機能を正常に発揮する状態に限定されず、少なくとも逆止弁付キャップを容器本体の口部に取付けたときに、これらのシールが行われ、吐出弁(及び吸気弁)が逆止機能を正常に発揮する状態を含む。
In the present invention, the state in which the discharge valve (and the intake valve) is formed means that when the base and the film are attached to the cap body, the upper surface of the base and the film and the cap body (seal means). The contact portion is sealed, and the upper surface of the base at the contact portion and the film are sealed, and the discharge valve (and the intake valve) is not limited to a state in which the check function is normally exhibited. When the cap is attached to the mouth of the container body, these seals are performed, and the discharge valve (and the intake valve) includes a state in which the check function is normally exhibited.
吸気弁75の気密性は、内容物の排出が可能な程度に保たれていればよく、例えば、注出容器2の転倒時などにおいて外容器21が不意に加圧され内容物が漏出してしまうことや、熱膨張により空間部20の空気が膨張して内容器11が加圧され内容物が漏出してしまうことを防止すべく、吸気弁75やリングキャップ81の雌ネジ37と外容器21の雄ネジ23との隙間から意図的に多少、空気が漏れるようにしてもよい。
The air-tightness of the intake valve 75 only needs to be maintained to such an extent that the contents can be discharged. For example, the outer container 21 is unexpectedly pressurized when the pouring container 2 falls, and the contents leak out. In order to prevent the air in the space 20 from expanding due to thermal expansion and pressurizing the inner container 11 to leak the contents, the female screw 37 of the intake valve 75 and the ring cap 81 and the outer container The air may intentionally leak to some extent from the gap with the male screw 23 of 21.
また吸気弁75は、フィルムを用いた逆止弁に限定されるものではなく、例えば、ボールや可動板部材等を用いた公知の逆止弁(図示省略)を取付けて構成することも可能である。さらに吸気弁75に代えて、空気を流通させる、孔や隙間等のリーク手段(図示省略)を設けてもよい。リーク手段は、外容器21を収縮させたときの空間部20からの空気の漏出量が、内容器11からの内容物の排出が可能な程度に制限されるように設けられ、外容器21の形状復元時には、空間部20に外気を導入する。

Further, instead of the intake valve 75, a leak means (not shown) such as a hole or a gap for circulating air may be provided. The leak means is provided so that the amount of air leakage from the space 20 when the outer container 21 is contracted is limited to the extent that the contents can be discharged from the inner container 11. At the time of shape restoration, outside air is introduced into the space 20.
第1実施形態の注出容器1では、吸気路33は、リングキャップ31に設けられているが、これに限定されるものではなく、吸気路33及び吸気弁75が外容器21の一部に設けられていてもよい。またこのとき吸気路33及び吸気弁75に代えて、外容器21に上述したリーク手段が設けられていてもよい。
In the dispensing container 1 of the first embodiment, the intake passage 33 is provided in the ring cap 31, but is not limited to this, and the intake passage 33 and the intake valve 75 are part of the outer container 21. It may be provided. At this time, instead of the intake passage 33 and the intake valve 75, the above-described leakage means may be provided in the outer container 21.
容器本体は、第1及び第2実施形態の注出容器1、2で用いた二重容器に限定されるものではなく、例えば、内容器が外容器に対して剥離可能に積層して形成されたデラミボトル(積層剥離型容器)等を用いてもよい。
The container body is not limited to the double container used in the dispensing containers 1 and 2 of the first and second embodiments. For example, the container body is formed by stacking the inner container so as to be peelable from the outer container. A delamination bottle (laminated peelable container) or the like may be used.
また容器本体は、二重容器に限定されるものではなく、例えば、プラスチックボトル、紙製液体容器、一般に市販されている袋容器等、内容物の排出に伴いながら収縮可能な容器本体を適宜選択して用いることができる。なお容器本体に二重容器を用いない場合は、吸気弁75は不要であり、吐出弁71のみが形成された逆止弁付キャップを好適に用いることができる。
