Description

本発明は、容器本体内への外気の侵入を防止可能な弁部材及び該弁部材を備える注出容器に関する。   The present invention relates to a valve member capable of preventing the intrusion of outside air into a container body and a dispensing container including the valve member.

醤油のような液体を収容する容器本体への外気の侵入を防止することで収容した液体の酸化を防止しつつ、液体を注出可能な容器として、逆止弁(吐出弁)を容器本体の口部に取付けて使用するものが多数開発されている。   A non-return valve (discharge valve) is installed on the container body as a container that can dispense liquid while preventing the outside air from entering the container body containing liquid such as soy sauce. Many things have been developed that are attached to the mouth.

このような注出容器では、内容物の注出に伴い容器本体が収縮するので、使用中に自立不能となり、見栄えも悪くなるという課題があった。この課題を解決すべく、内容物を収容する内容器と、内容器を収容する形状復元性を有し自立可能な外容器とで構成される二重構造の容器本体が用いられている。   In such a pouring container, the container body contracts as the contents are poured out, so that there is a problem that it becomes impossible to stand by itself during use and the appearance is deteriorated. In order to solve this problem, a double-structured container main body composed of an inner container for storing contents and an outer container having a shape restoring property and capable of supporting itself is used.

二重構造の容器本体を用いる場合、内容物を注出する際には外容器を加圧して変形させ、外容器と内容器との間の空間の流体を介して内容器を加圧し内容物を注出させる。このとき外容器と内容器との間の空間に流体を取込み、かつ内容物の注出時に外容器と内容器との間の空間からの流体の流出を防止する必要があり、このための逆止弁(吸気弁)が用いられている。   When using a container body with a double structure, when the contents are poured out, the outer container is pressurized and deformed, and the inner container is pressurized via the fluid in the space between the outer container and the inner container. To be poured out. At this time, it is necessary to take the fluid into the space between the outer container and the inner container and to prevent the fluid from flowing out from the space between the outer container and the inner container when the contents are poured out. A stop valve (intake valve) is used.

二重構造の容器本体を備える注出容器に用いる逆止弁の数を減らすべく、容器本体の口部に取付けられる吐出弁に吸気弁としての機能を付加する技術が開発されている(例えば、特許文献1、2参照)。   In order to reduce the number of check valves used in a dispensing container having a double-structured container body, a technique has been developed that adds a function as an intake valve to a discharge valve attached to the mouth of the container body (for example, (See Patent Documents 1 and 2).

The material of the outer container 21 is not limited to a specific material like the inner container 11. Depending on the contents to be stored, thermal stability, prevention of deterioration by ultraviolet rays, antistatic, antioxidant, water vapor barrier, other gas barrier properties (gas barrier properties), aroma storage properties, light shielding properties, etc. are required. In such a case, a material suitable for the required specifications may be used as appropriate. This point can be considered similarly to the inner container 11, and the above-described materials can be used.

外容器21は、口部22に穿設され内容器11との間の空間への外気の入口となる外気導入孔23と、口部22の外周面に設けられキャップ61を螺合及び係合させる雄ネジ24及び係止爪25とを備える。   The outer container 21 is formed by screwing and engaging an outer air introduction hole 23 that is formed in the mouth portion 22 and serves as an inlet for the outside air into a space between the inner container 11 and a cap 61 that is provided on the outer peripheral surface of the mouth portion 22. A male screw 24 and a locking claw 25 are provided.

外気導入孔23は、キャップ61が外容器21に取付けられたときに吸気流路9が形成されるように、キャップ61の筒部69に覆われる位置に設けられている。外気導入孔23の形状は、特定の形状に限定されるものではなく、例えば、円孔や矩形孔、星形孔等とすることができる。   The outside air introduction hole 23 is provided at a position covered by the cylindrical portion 69 of the cap 61 so that the intake passage 9 is formed when the cap 61 is attached to the outer container 21.

A piece 44, a seal cylinder 45, and a convex portion 46 that is in close contact with the distal end surface of the mouth portion 12 of the inner container 11 are provided.

基台41の材質は、特定の材質に限定されるものではなく、材料としては、ポリエチレンなどの合成樹脂材、金属、ガラス、炭素材、焼結材、木材等が例示され、これらの複合材や、蒸着、塗布、メッキ、金属箔等により表面を金属で被覆した材料等、用途、内容物等に応じて適宜選択した材料で形成することができる。例えば、基台41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、積層材その他材料で基台41を形成すればよい。   The material of the base 41 is not limited to a specific material, and examples of the material include synthetic resin materials such as polyethylene, metal, glass, carbon material, sintered material, and wood, and these composite materials Alternatively, it can be formed of a material appropriately selected according to the use, contents, etc., such as a material whose surface is coated with metal by vapor deposition, coating, plating, metal foil, or the like. For example, in order to prevent oxygen from entering the inner container 11 through the base 41, as in the case of the inner container 11, the base 41 is made of plastic, composite material, laminated material, or other material having excellent oxygen barrier properties and air barrier properties. May be formed.

弁孔42と切欠43とは、基台41の中心を挟んで位置決め片44の反対側に設けられている。この配置は、位置決め片44と後述するキャップ61の位置決め溝67とで弁部材31とキャップ61とが位置決めされたときに、切欠43とキャップ61の吸気口64との周方向の位置を一致させ、かつ弁孔42とキャップ61の注出口63とが基台41の中心を挟んで互いに反対側に位置するように決められている。   The valve hole 42 and the notch 43 are provided on the opposite side of the positioning piece 44 across the center of the base 41. In this arrangement, when the valve member 31 and the cap 61 are positioned by the positioning piece 44 and a positioning groove 67 of the cap 61, which will be described later, the circumferential positions of the notch 43 and the intake port 64 of the cap 61 are matched. In addition, the valve hole 42 and the spout 63 of the cap 61 are determined so as to be located on opposite sides of the center of the base 41.

切欠43とキャップ61の吸気口64との周方向の位置を一致させることで、フィルム51の吸気弁体部53とキャップ61の吸気口64との周方向の位置を一致させ、吸気弁39を形成することができる。   By matching the circumferential position of the notch 43 and the intake port 64 of the cap 61, the circumferential position of the intake valve body 53 of the film 51 and the intake port 64 of the cap 61 is matched, and the intake valve 39 is Can be formed.

また弁孔42とキャップ61の注出口63とが基台41の中心を挟んで互いに反対側に位置することで、内容物の充填時などに混入した内容器11内の空気又はガスが、注出容器1を傾けて内容物を注出する際に弁孔42の方へ移動するため外部に排出され易くなり好ましい。ただし、弁孔42とキャップ61の注出口63との位置関係は、これに限定されるものではない。   Further, since the valve hole 42 and the spout 63 of the cap 61 are located on opposite sides of the center of the base 41, the air or gas in the inner container 11 mixed at the time of filling the contents is injected. When the contents are poured out by tilting the outlet container 1, it moves toward the valve hole 42, which is preferable because it is easily discharged to the outside. However, the positional relationship between the valve hole 42 and the spout 63 of the cap 61 is not limited to this.

要するに弁孔42、切欠43、及び位置決め片44の配置は、少なくとも切欠43とキャップ61の吸気口64との周方向の位置が一致するように、キャップ61の吸気口64及び位置決め溝67の配置に合わせて決めればよい。   In short, the valve holes 42, the notches 43, and the positioning pieces 44 are arranged so that at least the circumferential positions of the notches 43 and the inlets 64 of the cap 61 coincide with each other. You can decide according to.

弁孔42は、平板部に3箇所穿設された円孔であり、内容器11内の内容物が流入可能にシール筒45よりも内側に穿設されている。ただし弁孔42の数及び形状は、これに限定されるものではない。   The valve hole 42 is a circular hole drilled at three locations in the flat plate portion, and is drilled inside the seal cylinder 45 so that the contents in the inner container 11 can flow in. However, the number and shape of the valve holes 42 are not limited to this.

切欠43は、吸気弁39の開閉を可能とすべく、切欠43上を覆うフィルム51の吸気弁体部53が上下方向からの流体(空気)の圧力を受けて上下動可能に、平板部の周縁部の一部が開口する形で設けられている。   The cutout 43 is formed on the flat plate portion so that the intake valve body 53 of the film 51 covering the cutout 43 can be moved up and down by receiving the pressure of fluid (air) from the vertical direction so that the intake valve 39 can be opened and closed. A part of the peripheral edge is provided in an open shape.

位置決め片44は、平板部の周縁部の上面の一部が部分円弧上に隆起した形で形成されており、後述するキャップ61の押え面65に設けられる位置決め溝67に嵌り込み、弁部材31とキャップ61との周方向の位置決めを行う。   The positioning piece 44 is formed such that a part of the upper surface of the peripheral portion of the flat plate portion is raised on a partial arc, and is fitted into a positioning groove 67 provided in a pressing surface 65 of the cap 61 described later, and the valve member 31. And the cap 61 are positioned in the circumferential direction.

なお位置決め片44の形状、及び本発明の注出容器における弁部材とキャップとの位置決め方法は、特定の形状や方法に限定されるものではなく、例えば、後述する第3実施形態の注出容器3で用いる位置決め片82、位置決めピン83等を用いてもよい。   The shape of the positioning piece 44 and the positioning method of the valve member and the cap in the pouring container of the present invention are not limited to a specific shape or method. For example, the pouring container of the third embodiment to be described later The positioning piece 82 and the positioning pin 83 used in 3 may be used.

シール筒45は、基台41の下面に円筒状に形成され、内容器11の口部12に嵌め込まれ、内容器11の口部12の内周面に密接してシールを行う。シール筒45は、内容器11の口部12に嵌め込み易いように先端部分が先細に形成されている。   The seal cylinder 45 is formed in a cylindrical shape on the lower surface of the base 41, is fitted into the mouth portion 12 of the inner container 11, and seals in close contact with the inner peripheral surface of the mouth portion 12 of the inner container 11. The seal cylinder 45 has a tapered tip so that it can be easily fitted into the mouth 12 of the inner container 11.

凸部46は、基台41の下面にリング状に設けられた断面が半円状の突起であり、内容器11の口部12の先端面に密接してシールを行う。   The convex portion 46 is a projection having a semicircular cross section provided in a ring shape on the lower surface of the base 41, and seals in close contact with the distal end surface of the mouth portion 12 of the inner container 11.

なお内容器11の口部12のシールを行う方法は、シール筒45及び凸部46を用いた方法に限定されるものではなく、例えば、どちらか一方のみを用いてもよく、シール筒45、凸部46を用いずに基台41の下面でシールを行うようにしてもよい。なおシール筒45及び凸部46の形状も、特定の形状に限定されるものではない。またガスケット(パッキン)等を介してシールを行うようにしてもよく、基台41の下面周縁部と内容器11の口部12の先端面とを接着してもよい。   The method for sealing the mouth portion 12 of the inner container 11 is not limited to the method using the seal tube 45 and the convex portion 46, and for example, only one of them may be used. You may make it seal on the lower surface of the base 41, without using the convex part 46. FIG. The shapes of the seal cylinder 45 and the convex portion 46 are not limited to specific shapes. Further, sealing may be performed through a gasket (packing) or the like, or the lower surface peripheral portion of the base 41 and the distal end surface of the mouth portion 12 of the inner container 11 may be bonded.

フィルム51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51の厚さは、特に限定されるものではなく用途、内容物、材質、接着方法等に応じて適宜選択して使用することができる。但し、弁部材31と後述するキャップ61の凸部68とのシール性の点からはフィルム51は薄い方が好ましい。この場合、フィルム51が吐出弁38及び吸気弁39の弁体としての機能を発揮し、フィルム51を基台41に接着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。弁部材31とキャップ61の凸部68とのシール性については後述する。フィルム51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10〜数百μm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 51 is a thin film, and includes a thin film having flexibility, flexibility, and stretchability. The thickness of the film 51 is not particularly limited, and can be appropriately selected and used according to the application, contents, material, adhesion method, and the like. However, it is preferable that the film 51 is thin from the viewpoint of the sealing performance between the valve member 31 and the convex portion 68 of the cap 61 described later. In this case, it is needless to say that the film 51 functions as a valve body of the discharge valve 38 and the intake valve 39 and should not be damaged when the film 51 is bonded to the base 41. The sealing performance between the valve member 31 and the convex portion 68 of the cap 61 will be described later. If an example of the thickness of the film 51 is shown, when the content is a liquid with a relatively low viscosity such as soy sauce (general soy sauce), it is about 10 to several hundred μm with a polyethylene film. However, it is not limited to this value.

フィルム51の材質は、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、特定の材質に限定されるものではなく、用途、内容物、基台41への接着方法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51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を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51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。   The material of the film 51 is 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, or the like. Although illustrated, it is not limited to a specific material, According to a use, the content, the adhesion method to the base 41, etc., it can select suitably and can be used. For example, in order to prevent oxygen from entering the inner container 11 through the film 51, 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 barriers. Plastics, composite materials, laminated materials, etc. that are excellent in properties can be suitably used. However, since the film 51 is in a thin film shape, it is easier for gas to pass through compared to the inner container 11 and the like, and therefore it is necessary to select a material in consideration of this point.

フィルム51は、基台41と略同一の直径を有する弓形の部分円形状であり、基台41の上面に剥離自在に密着して吐出弁38の弁体となる吐出弁体部52と、基台41の切欠43を覆い吸気弁39の弁体となる吸気弁体部53とを有し、基台41の上面に重ねられ吐出弁体部52と吸気弁体部53とが気密に隔てられるように接着される。本実施形態の注出容器1のフィルム51は、吐出弁体部52及び吸気弁体部53を除く部分全域が基台41の上面に接着されている。なおフィルム51の直線部分の一部は、接着されずに吐出弁38の出口となる吐出口54を形成する。   The film 51 has an arcuate partial circular shape having substantially the same diameter as the base 41, a discharge valve body portion 52 that is detachably adhered to the upper surface of the base 41 and serves as a valve body of the discharge valve 38, and a base An intake valve body portion 53 that covers the notch 43 of the base 41 and serves as a valve body of the intake valve 39 is superimposed on the upper surface of the base 41 and the discharge valve body portion 52 and the intake valve body portion 53 are airtightly separated. So that it is glued. The film 51 of the dispensing container 1 of the present embodiment is bonded to the upper surface of the base 41 in the entire area excluding the discharge valve body 52 and the intake valve body 53. A part of the straight part of the film 51 forms a discharge port 54 that becomes an outlet of the discharge valve 38 without being bonded.

吐出弁体部52は、基台41の弁孔42を覆い、弁孔42から吐出口54へ内容物を流通可能に基台41の上面に剥離自在に密着しているフィルム51の一部であり、吐出弁体部52を弁体、基台41の上面を弁座、弁孔42を入口、吐出口54を出口とする吐出弁38を形成する。吐出弁体部52の形状は、特定の形状に限定されるものではなく、例えば、蛇行した形で設けられていてもよい。   The discharge valve body 52 is a part of the film 51 that covers the valve hole 42 of the base 41 and is in close contact with the upper surface of the base 41 so as to allow the contents to flow from the valve hole 42 to the discharge port 54. The discharge valve body 52 is a valve body, the upper surface of the base 41 is a valve seat, the valve hole 42 is an inlet, and the discharge valve 38 is an outlet. The shape of the discharge valve body 52 is not limited to a specific shape, and may be provided in a meandering shape, for example.

吸気弁体部53は、基台41の切欠43を覆っているフィルム51の一部であり、吸気弁体部53を弁体、キャップ61の押え面65に位置する吸気口64の出口周囲66を弁座、吸気口64を入口とする吸気弁39を形成する。吸気弁体部53は、少なくとも吸気口64の出口を閉塞可能な大きさとなっている。   The intake valve body portion 53 is a part of the film 51 that covers the notch 43 of the base 41. The intake valve body portion 53 serves as a valve body, and the outlet periphery 66 of the intake port 64 located on the holding surface 65 of the cap 61. Is formed as a valve seat and an intake port 64 as an inlet. The intake valve body 53 has a size that can close at least the outlet of the intake port 64.

フィルム51の接着方法は、特定の方法に限定されるものではなく、後述するレーザ溶着の他、熱溶着、接着剤を用いた接着等の方法を用いることができる。但し、次の点を考慮した接着を実施する必要がある。   The method for adhering the film 51 is not limited to a specific method, and other methods such as laser welding, which will be described later, thermal welding, and adhesion using an adhesive can be used. However, it is necessary to perform bonding in consideration of the following points.

本実施形態の注出容器1のように弁部材31の上面と後述するキャップ61の押え面65(凸部68)とを密接させる場合、弁部材31の上面の平滑度が非常に重要である。弁部材31の上面が十分に平滑であれば、弁部材31の上面をキャップ61の押え面65(凸部68)に直接当接させても、気密を確保することができるが、弁部材31の上面の平滑度が不十分であれば、ガスケット(パッキン)等を介在させる必要がある。   When the upper surface of the valve member 31 and a pressing surface 65 (convex portion 68) of the cap 61 described later are brought into close contact with each other as in the dispensing container 1 of the present embodiment, the smoothness of the upper surface of the valve member 31 is very important. . If the upper surface of the valve member 31 is sufficiently smooth, even if the upper surface of the valve member 31 is brought into direct contact with the pressing surface 65 (convex portion 68) of the cap 61, airtightness can be ensured. If the smoothness of the upper surface is insufficient, a gasket (packing) or the like needs to be interposed.

特に平板状の基台41にフィルム51を部分的に重ねて形成した弁部材31において、弁部材31の上面に、フィルム51に被覆された部分と被覆されていない部分とが含まれ、弁部材31の上面をキャップ21の押え面65(凸部68)に直接、密接させるには、フィルム51に被覆された部分と被覆されていない部分との間に段差がないか、段差があったとしても密接可能な段差でなければならず、フィルム51に被覆された部分と被覆されていない部分との境界が重要である。   In particular, in the valve member 31 formed by partially overlapping the film 51 on the flat base 41, the upper surface of the valve member 31 includes a portion covered with the film 51 and a portion not covered, In order to directly bring the upper surface of 31 into close contact with the pressing surface 65 (convex portion 68) of the cap 21, there is no step between the portion covered with the film 51 and the portion not covered, or there is a step. The step must be close enough, and the boundary between the portion covered with the film 51 and the portion not covered is important.

弁部材31の上面に含まれるフィルム51に被覆された部分と被覆されていない部分との段差には、フィルム51の厚さ及び接着方法が大きく関与する。弁部材31の上面に含まれるフィルム51に被覆された部分と被覆されていない部分との段差をなくすには、フィルム51の厚さは薄い方が好ましい。また接着方法は、フィルム51を基台41に接着させたとき、フィルム51に被覆された部分と被覆されていない部分との間に段差が生じない、あるいは段差が生じたとしても密接可能な段差となるような接着方法を採用する。以下、本実施形態において、フィルム51に被覆された部分と被覆されていない部分との間に段差がないとは、高さが同一で物理的に段差がない場合の他、密接可能な段差、つまり段差がないと同一視できる程度の段差を含むものとする。   The thickness of the film 51 and the bonding method are largely involved in the step between the portion covered with the film 51 and the portion not covered with the upper surface of the valve member 31. In order to eliminate the step between the portion covered with the film 51 and the portion not covered with the upper surface of the valve member 31, it is preferable that the thickness of the film 51 is thin. In addition, when the film 51 is bonded to the base 41, there is no step between the portion covered by the film 51 and the portion not covered, or a step that can be intimate even if a step occurs. Adhesion method will be adopted. Hereinafter, in the present embodiment, there is no step between the portion covered with the film 51 and the portion not covered with, in addition to the case where the height is the same and there is no physical step, the step that can be closely contacted, That is, it is assumed to include a level difference that can be identified with no level difference.

弁部材31の上面に含まれるフィルム51に被覆された部分と被覆されていない部分との間に段差を生じさせない接着方法として、後述のレーザ溶着方法を好適に使用することができる。この他、接着剤を使用した接着方法において、フィルム51と基台41とを部分的に溶解させる方法もある。基台41のうちフィルム51が重ねられる領域を予め薄く加工しておく方法も考えられるが、基台41の加工が必要であり、さらに基台41とフィルム51との位置合わせが必要となり、製造に手間がかかる。   As an adhesion method that does not cause a step between the portion covered with the film 51 included in the upper surface of the valve member 31 and the portion not covered, a laser welding method described later can be suitably used. In addition, in the bonding method using an adhesive, there is a method in which the film 51 and the base 41 are partially dissolved. A method of thinly processing a region of the base 41 where the film 51 is overlapped in advance is also conceivable. However, the base 41 needs to be processed, and the base 41 and the film 51 need to be aligned. It takes time and effort.

基台41とフィルム51との接着には、例えばレーザ溶着を好適に用いることができる。レーザ溶着を行う際には、載置台(図示省略)に基台41をセットし、その上から基台41よりも大きな矩形のフィルム材(図示省略)を部分的に被せ、弁孔42がフィルム材に覆われ、かつフィルム材の一端が基台41の位置決め片44の端部よりも内側に位置するように位置を合わせ、その上からガラス板(図示省略)でフィルム材を押え、ガラス板の上から接着する部分を走査するようにレーザを照射する。   For adhesion between the base 41 and the film 51, for example, laser welding can be suitably used. When performing laser welding, a base 41 is set on a mounting table (not shown), and a rectangular film material (not shown) larger than the base 41 is partially covered thereon, and the valve hole 42 is a film. The film material is covered, and the film material is positioned so that one end of the film material is located on the inner side of the end of the positioning piece 44 of the base 41, and the film material is pressed from above with a glass plate (not shown). A laser is irradiated so as to scan a portion to be bonded from above.

レーザは、ガラス板及びフィルム材を透過し、基台41に吸収される。レーザが吸収されると基台41の上面が発熱して溶融し、フィルム材が溶着される。溶着の際、溶着部は、熱により膨潤するが、レーザ照射を停止すると冷却に伴い収縮する。このときフィルム材の上にはガラス板が載置されているので、溶着部は、フィルム材が重ねられていない基台41と同一高さ、あるいは同一視できる高さとなる。このため弁部材31の上面に含まれるフィルム材に被覆された部分と被覆されていない部分との間に段差は生じない。   The laser passes through the glass plate and the film material and is absorbed by the base 41. When the laser is absorbed, the upper surface of the base 41 generates heat and melts, and the film material is welded. During welding, the welded portion swells due to heat, but when laser irradiation is stopped, it shrinks with cooling. At this time, since the glass plate is placed on the film material, the welded portion has the same height as the base 41 on which the film material is not stacked or a height at which the same can be seen. For this reason, a level | step difference does not arise between the part coat | covered with the film material contained in the upper surface of the valve member 31, and the part which is not coat | covered.

溶着後は、基台41の縁に沿ってレーザを照射し、フィルム材を切断すれば弁部材31を得ることができる。このようにレーザ溶着を用いると製造がさらに容易となる。   After welding, the valve member 31 can be obtained by irradiating a laser along the edge of the base 41 and cutting the film material. When laser welding is used in this way, manufacturing becomes even easier.

またレーザ溶着による基台41とフィルム材との溶着時には、フィルム材をガラス板で予め押えた状態から溶着が行われるので、フィルム51に吐出弁38のシール不良の原因となる皺が生じ難い。   Further, when the base 41 and the film material are welded by laser welding, the film material is welded from a state in which the film material is previously pressed by a glass plate, so that the film 51 is unlikely to cause wrinkles that cause a sealing failure of the discharge valve 38.

基台41とフィルム51との接着をレーザ溶着で行う場合は、基台41がレーザを吸収する材料、フィルム51がレーザを透過させる材料である必要がある。このような基台41の材料としては、例えばカーボンブラックや酸化チタンなどを添加したポリエチレンなどの合成樹脂材の他、レーザ88を吸収する公知の材料を適宜選択して用いることができる。またフィルム51の材料としては、例えば透明又は半透明のポリエチレンフィルムなどの合成樹脂製フィルムの他、レーザを透過する公知の材料を適宜選択して用いることができる。   When the base 41 and the film 51 are bonded by laser welding, the base 41 needs to be a material that absorbs laser and the film 51 needs to be a material that transmits laser. As a material of such a base 41, for example, a known material that absorbs the laser 88 can be appropriately selected and used in addition to a synthetic resin material such as polyethylene to which carbon black, titanium oxide, or the like is added. As a material of the film 51, for example, a known material that transmits laser can be appropriately selected and used in addition to a synthetic resin film such as a transparent or translucent polyethylene film.

載置台は、基台41を載置し位置決め可能であればよく、特定の形状、材料に限定されるものではない。   The mounting table is not limited to a specific shape and material as long as the base 41 can be mounted and positioned.

ガラス板は、レーザ溶着を行う際にフィルム材の浮き上がりを防止するとともに、フィルム材に加わる熱を放熱させる。フィルム材に過度に熱が加わると焼損する恐れがあるが、ガラス板により放熱されるためフィルム材の焼損が防止される。なおガラス板を冷却エアーや冷却水などで冷却するようにしてもよい。   The glass plate prevents the film material from lifting when laser welding is performed, and dissipates heat applied to the film material. If excessive heat is applied to the film material, it may be burned out, but since the heat is radiated by the glass plate, the film material is prevented from being burned out. The glass plate may be cooled with cooling air or cooling water.

ガラス板は、例えば硬質耐熱ガラスプレート等を用いることができるが、レーザを透過し、かつフィルム材の浮き上がりを防止可能であれば、特定の材料に限定されるものではない。またガラスに限定されるものではない。   As the glass plate, for example, a hard heat-resistant glass plate or the like can be used. However, the glass plate is not limited to a specific material as long as it can transmit a laser and prevent the film material from being lifted. Moreover, it is not limited to glass.

またガラス板などの押え手段に代えて、又はこれに加えて、真空ポンプ(図示省略)等を用いて基台41の弁孔42からフィルム材を吸引し、基台41にフィルム材を吸着(密着)させた状態でレーザ溶着を行うこともできる。   Further, instead of or in addition to the pressing means such as a glass plate, a film material is sucked from the valve hole 42 of the base 41 using a vacuum pump (not shown) or the like, and the film material is adsorbed to the base 41 ( Laser welding can also be performed in a state of being in close contact.

レーザ溶着に用いるレーザ光源は、例えば半導体レーザやYAGレーザ、炭酸ガスレーザなど公知のものを適宜選択して用いることができる。レーザの強度は、基台41、フィルム材、ガラス板の材質、厚み等に合わせ、フィルム材及びガラス板を溶融せずに透過し、かつ、基台41を溶融するように調節する必要がある。   As the laser light source used for laser welding, for example, a known laser light source such as a semiconductor laser, a YAG laser, or a carbon dioxide gas laser can be appropriately selected and used. The intensity of the laser needs to be adjusted according to the base 41, the material of the film material, the glass plate, the thickness, etc. so that the film material and the glass plate can be transmitted without melting and the base 41 can be melted. .

And a locking claw 71 to be engaged.

キャップ61の材質は、特定の材質に限定されるものではなく、材料としては、ポリエチレンなどの合成樹脂材、金属、ガラス、炭素材、焼結材、木材等が例示され、これらの複合材や、蒸着、塗布、メッキ、金属箔等により表面を金属で被覆した材料等、用途、内容物等に応じて適宜選択した材料で形成することができる。例えば、キャップ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、積層材その他材料でキャップ61を形成すればよい。   The material of the cap 61 is not limited to a specific material, and examples of the material include synthetic resin materials such as polyethylene, metal, glass, carbon material, sintered material, wood, and the like. It can be formed of a material appropriately selected according to the use, contents, etc., such as a material whose surface is covered with metal by vapor deposition, coating, plating, metal foil or the like. For example, in order to prevent oxygen from entering the inner container 11 through the cap 61, the cap 61 is formed of plastic, composite material, laminated material, or other material having excellent oxygen barrier properties and air barrier properties as in the case of the inner container 11. do it.

注出口63と位置決め溝67とは、中心を挟んで吸気口64の反対側に位置するように設けられている。このような配置とすることで弁部材31の位置決め片44を位置決め溝67に嵌め込んだときに、注出口63と基台41の弁孔42とが中心を挟んで互いに反対側に配置され、吸気口64と切欠43(吸気弁体部53)とが周方向に一致する位置に配置される。   The spout 63 and the positioning groove 67 are provided so as to be located on the opposite side of the intake port 64 across the center. With this arrangement, when the positioning piece 44 of the valve member 31 is fitted in the positioning groove 67, the spout 63 and the valve hole 42 of the base 41 are arranged on opposite sides with the center therebetween, The intake port 64 and the notch 43 (intake valve body portion 53) are arranged at positions that coincide with the circumferential direction.

吸気口64は、出口が押え面65に位置するように設けられており、吸気口64の出口周囲66が吸気弁39の弁座となる。吸気口64は、出口が吸気弁体部53、又は吸気弁体部53と弁部材31の上面の一部とで閉塞可能な大きさで設けられている。   The intake port 64 is provided such that the outlet is positioned on the pressing surface 65, and the outlet periphery 66 of the intake port 64 serves as the valve seat of the intake valve 39. The intake port 64 is provided in such a size that the outlet can be closed by the intake valve body portion 53 or the intake valve body portion 53 and a part of the upper surface of the valve member 31.

なお本実施形態の注出容器1では、吸気口64の出口周囲66の高さが弁部材31の上面の高さと略同一となっているが、これに限定されるものではなく、図5に示すように吸気口64の出口周囲66の高さが弁部材31の上面の高さと異なっていても、吸気弁体部53により吸気口64の出口を閉塞可能であればよい。   In the dispensing container 1 of the present embodiment, the height of the outlet periphery 66 of the intake port 64 is substantially the same as the height of the upper surface of the valve member 31, but this is not a limitation, and FIG. As shown, even if the height of the outlet periphery 66 of the intake port 64 is different from the height of the upper surface of the valve member 31, it is sufficient if the intake valve body portion 53 can close the outlet of the intake port 64.

位置決め溝67は、基台41の位置決め片44が嵌り込み、キャップ61と弁部材31との互いの周方向の位置を規制可能に基台41の位置決め片44と略同一の形状でキャップ61の押え面65の一部に凹状に形成されている。   The positioning groove 67 is fitted in the positioning piece 44 of the base 41 and can control the position of the cap 61 and the valve member 31 in the circumferential direction of the cap 41 and has substantially the same shape as the positioning piece 44 of the base 41. A part of the pressing surface 65 is formed in a concave shape.

凸部68は、押え面65にリング状に設けられた断面が半円状の突起であり、弁部材31の吐出弁体部52と吸気弁体部53との間を遮断するように弁部材31の上面に密接してシールを行う。凸部68の形状は、特定の形状に限定されるものではなく、例えば、断面が逆三角形等でもよい。また凸部68を設けずとも押え面65と弁部材31の上面とが密接してシール可能であれば、凸部68を設けなくてもよい。また凸部68に代えて、Oリングやガスケット(パッキン)等を介してシールを行うようにしてもよく、押え面65と弁部材31の上面とを接着してもよい。   The convex portion 68 is a protrusion having a semicircular cross section provided in a ring shape on the pressing surface 65, and the valve member so as to block between the discharge valve body portion 52 and the intake valve body portion 53 of the valve member 31.

次に注出容器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。内容器11内に醤油を充填し、シール筒45を内容器11の口部12に嵌め込み弁部材31を内容器11の口部12に取付け、その上からキャップ61を被せ、位置決め溝67に弁部材31の位置決め片44を嵌め込んだ状態でキャップ61を外容器21に螺合させ、係止爪25、71同士を係合させる。   Next, the usage method will be exemplified by using the dispensing container 1 as a soy sauce bottle for preventing oxidation. The inner container 11 is filled with soy sauce, the seal cylinder 45 is fitted into the mouth part 12 of the inner container 11, the valve member 31 is attached to the mouth part 12 of the inner container 11, the cap 61 is placed thereon, and the valve is placed in the positioning groove 67. With the positioning piece 44 of the member 31 fitted, the cap 61 is screwed into the outer container 21 and the locking claws 25 and 71 are engaged with each other.

キャップ61を外容器21に取付けると、内容器11が密封されるとともに、キャップ61の凸部68が弁部材31の上面に密接し吐出弁体部52と吸気弁体部53とが気密に遮断され、内容器11内から吐出弁38を通りキャップ61の注出口63へ醤油を注出させる注出流路8と、キャップ61の吸気口64から吸気弁39、外容器21の外気導入孔23を通り外容器21と内容器11との間の空間へ外気を吸気する吸気流路9とが互いに気密に遮断された状態で形成される。なお吸気流路9内の気密性は、外容器21の収縮時に内容器11内の内容物を排出可能な程度に保たれていればよく、吸気弁39やキャップ61の雌ネジ70と外容器21の雄ネジ24との隙間からの多少の空気の流出は許容される。   When the cap 61 is attached to the outer container 21, the inner container 11 is sealed, the convex portion 68 of the cap 61 is in close contact with the upper surface of the valve member 31, and the discharge valve body portion 52 and the intake valve body portion 53 are shut off in an airtight manner. The discharge passage 8 through which the soy sauce is discharged from the inner container 11 through the discharge valve 38 to the outlet 63 of the cap 61, the intake valve 39 from the intake port 64 of the cap 61, and the outside air introduction hole 23 of the outer container 21. And the intake passage 9 for sucking outside air into the space between the outer container 21 and the inner container 11 is formed in a state of being airtightly blocked from each other. It should be noted that the airtightness in the intake passage 9 is only required to be maintained so that the contents in the inner container 11 can be discharged when the outer container 21 contracts. The intake valve 39 and the female screw 70 of the cap 61 and the outer container Some outflow of air from the gap with the 21 male screw 24 is allowed.

キャップ61を外容器21に取付けた後は、注出容器1を上向きとしたまま外容器21を収縮させる。外容器21を収縮させると外容器21と内容器11との間の空間が加圧されて吸気弁39が閉じ、内容器11内が加圧される。内容器11内が加圧されるとフィルム51の吐出弁体部52が浮き上がって吐出弁38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38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。   After the cap 61 is attached to the outer container 21, the outer container 21 is contracted with the dispensing container 1 facing upward. When the outer container 21 is contracted, the space between the outer container 21 and the inner container 11 is pressurized, the intake valve 39 is closed, and the inside of the inner container 11 is pressurized. When the inside of the inner container 11 is pressurized, the discharge valve body 52 of the film 51 rises and the discharge valve 38 opens, and the air or gas remaining in the inner container 11 is discharged. As a result, the inside of the inner container 11 is filled with soy sauce, and air is prevented from entering by the discharge valve 38, 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を収縮させると、内容器11内が加圧され弁孔42から吐出弁38へ醤油が流れ込み、フィルム51の吐出弁体部52が浮き上がって吐出弁38が開弁し、醤油が吐出口54から吐出されて注出口63から注がれる。   When pouring out the soy sauce, when the outer container 21 is contracted by tilting the pouring container 1 downward, the inner container 11 is pressurized and the soy sauce flows into the discharge valve 38 from the valve hole 42, and the discharge valve of the film 51. The body 52 rises and the discharge valve 38 opens, soy sauce is discharged from the discharge port 54 and poured from the spout 63.

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41の上面とフィルム51の吐出弁体部52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51の吐出弁体部52が基台41の上面に素早く密着して吐出弁38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との間の空間が負圧となり、吸気弁39が開弁して外容器21と内容器11との間の空間に外気が流入し、外容器21が元の形状に戻る。   If the shrinkage of the outer container 21 is stopped and the dispensing container 1 is returned upward, the soy sauce interposed between the action of the negative pressure in the inner container 11 and the upper surface of the base 41 and the discharge valve body 52 of the film 51 Due to the capillary suction force, the discharge valve body 52 of the film 51 quickly comes into close contact with the upper surface of the base 41 and the discharge valve 38 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 between the outer container 21 and the inner container 11 becomes negative pressure, the intake valve 39 is opened, and the outside air is in the space between the outer container 21 and the inner container 11. 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は、フィルム51を基台41の上面に重ねて接着するだけで吐出弁38及び吸気弁39を形成可能な弁部材31を得ることができ、さらに弁部材31を内容器11の口部12に取付け、キャップ61を外容器21に取付けるだけで吐出弁38及び吸気弁39を形成することができるので、製造が非常に容易であり、低コストである。   As described above, the dispensing container 1 of the present embodiment can obtain the valve member 31 that can form the discharge valve 38 and the intake valve 39 simply by overlaying and bonding the film 51 on the upper surface of the base 41. Since the discharge valve 38 and the intake valve 39 can be formed simply by attaching the valve member 31 to the mouth portion 12 of the inner container 11 and attaching the cap 61 to the outer container 21, manufacturing is very easy and at low cost. is there.

また弁部材31とキャップ61との周方向の位置決め手段を備えるので、吸気弁体部53と吸気口64との位置決めを確実に、かつ容易に行うことができる。   Moreover, since the positioning means of the circumferential direction of the valve member 31 and the cap 61 is provided, the positioning of the intake valve body 53 and the intake port 64 can be performed reliably and easily.

At the upper end of the mouth member, a flange 19 is formed which is attached to the front end surface of the mouth portion 22 of the outer container 21. The lower surface of the flange 19 is tightly sealed to the front end surface of the mouth portion 22 of the outer container 21. The convex part 20 which performs is provided in the ring shape. Since the convex portion 20 is the same as the convex portions 46 and 68 of the valve member 31 and the cap 61, description thereof is omitted.

本実施形態の注出容器3における、これらの位置決め手段は、第1実施形態の注出容器1における位置決め手段と同様、少なくとも基台81の切欠43とキャップ91の吸気口64との周方向の位置を一致させ、好ましくは、基台81の弁孔42とキャップ91の注出口63とが基台81の中心を挟んで互いに反対側に位置するように設けられる。   These positioning means in the pouring container 3 of this embodiment are the same as the positioning means in the pouring container 1 of the first embodiment in the circumferential direction of at least the notch 43 of the base 81 and the air inlet 64 of the cap 91. The positions are matched, and preferably, the valve hole 42 of the base 81 and the spout 63 of the cap 91 are provided on the opposite sides of the center of the base 81.

以上のように、本発明の注出容器の弁部材とキャップとの周方向の位置決め手段は、特定のものに限定されるものではなく、製造方法、材料コスト等を考慮し適宜最適なものを用いることができる。   As described above, the positioning means in the circumferential direction between the valve member and the cap of the dispensing container of the present invention is not limited to a specific one, and an optimum one is appropriately selected in consideration of the manufacturing method, material cost, etc. Can be used.

図9は、本発明の第4実施形態の注出容器4の要部断面図である。図6に示す第2実施形態の注出容器2と同一の構成には同一の符号を付して説明を省略する。第4実施形態の注出容器4は、第2実施形態の注出容器2と基本的構成は同じであるが、外気導入孔103が外容器105ではなく、内容器101の口部材102に設けられている。   FIG. 9 is a cross-sectional view of an essential part of the dispensing container 4 according to the fourth embodiment of the present invention. The same components as those of the dispensing container 2 of the second embodiment shown in FIG. The dispensing container 4 of the fourth embodiment has the same basic configuration as the dispensing container 2 of the second embodiment, but the outside air introduction hole 103 is not provided in the outer container 105 but in the mouth member 102 of the inner container 101. It has been.

外気導入孔103は、フランジ19の外周面から内容器101と外容器105との間の空間へ外気を流通可能に口部材102にL字状に穿設されている。このように外気導入孔103は、内容器101に設けられていてもよい。   The outside air introduction hole 103 is formed in an L shape in the mouth member 102 so that the outside air can flow from the outer peripheral surface of the flange 19 to the space between the inner container 101 and the outer container 105. Thus, the outside air introduction hole 103 may be provided in the inner container 101.

図10は、本発明の弁部材の変形例を示す図である。図1から図4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。なお以下の変形例において、説明の簡略化のため位置決め手段は省略している。   FIG. 10 is a view showing a modification of the valve member of the present invention. The same components as those of the dispensing container 1 of the first embodiment shown in FIG. 1 to FIG. In the following modifications, the positioning means is omitted for the sake of simplicity.

図10(a)に示す変形例では、弁部材31aの基台41aに切欠43が設けられておらず、フィルム51aの直径が基台41aの直径よりも大きくなっている。本変形例の弁部材31aでは、フィルム51aの基台41aに接していない部分が吸気弁体部53として機能し、吸気弁体部53の一部又は全部とキャップ61の吸気口64とで吸気弁39を形成する。   In the modification shown in FIG. 10A, the notch 43 is not provided in the base 41a of the valve member 31a, and the diameter of the film 51a is larger than the diameter of the base 41a. In the valve member 31a of this modification, the portion of the film 51a that is not in contact with the base 41a functions as the intake valve body portion 53, and the intake valve body portion 53 and a portion of the intake valve body portion 53 and the intake port 64 of the cap 61 take in the intake air. A valve 39 is formed.

図10(b)に示す変形例では、弁部材31bの基台41bに切欠43が設けられておらず、フィルム51bが基台41bの直径よりも大きい円形に形成されている。またフィルム51bには、吐出口54に代えて、吐出孔55が穿設されている。本変形例の弁部材31bでは、フィルム51bの基台41bに接していない部分が吸気弁体部53として機能し、吸気弁体部53の一部又は全部とキャップ61の吸気口64とで吸気弁39を形成する。   In the modification shown in FIG. 10B, the notch 43 is not provided in the base 41b of the valve member 31b, and the film 51b is formed in a circular shape larger than the diameter of the base 41b. In addition, instead of the discharge port 54, a discharge hole 55 is formed in the film 51b. In the valve member 31b of this modification, the portion of the film 51b that is not in contact with the base 41b functions as the intake valve body portion 53, and the intake valve body portion 53 and a portion of the intake valve body portion 53 and the intake port 64 of the cap 61 take in the intake air. A valve 39 is formed.

図10(c)に示す変形例では、弁部材31cの基台41cに、切欠43に代えて、孔47が設けられている。孔47は、平面視において一部がキャップ61の吸気口64の出口と重なる位置に設けられる。本変形例の弁部材31cのフィルム51cは、孔47の平面視において吸気口64の出口と重なる一部を覆い、かつ吸気口64の出口を開閉可能な直径を有し、吸気口64の出口を開閉する部分が吸気弁体部53となる。   In the modification shown in FIG. 10C, a hole 47 is provided in the base 41 c of the valve member 31 c instead of the notch 43. The hole 47 is provided at a position where a part thereof overlaps the outlet of the intake port 64 of the cap 61 in plan view. The film 51c of the valve member 31c of this modification has a diameter that covers a part of the hole 47 that overlaps with the outlet of the intake port 64 in a plan view and that can open and close the outlet of the intake port 64. The part that opens and closes the intake valve body 53.

本変形例の弁部材31cの吸気弁39は、閉弁時には、孔47を覆う吸気弁体部53の下面が孔47から流入する流体(空気)の圧力を受けて吸気弁体部53が浮き上がり、キャップ61の吸気口64を閉塞する。開弁時には、吸気弁体部53の上面が吸気口64から流入する外気の圧力を受けて吸気弁体部53が孔47に潜り込み、吸気弁体部53と孔47との隙間から外気を流入させる。   When the intake valve 39 of the valve member 31c of this modification is closed, the lower surface of the intake valve body 53 covering the hole 47 receives the pressure of the fluid (air) flowing from the hole 47 and the intake valve body 53 is lifted. The intake port 64 of the cap 61 is closed. When the valve is opened, the upper surface of the intake valve body 53 receives the pressure of the outside air flowing in from the intake port 64, the intake valve body 53 enters the hole 47, and the outside air flows in through the gap between the intake valve body 53 and the hole 47. Let

図10(d)に示す変形例では、弁部材31dの基台41dに、切欠43に代えて、傾斜部48が設けられている。本変形例の弁部材31dでは、フィルム51の吸気弁体部53が基台41dの傾斜部48上で上下動して吸気弁39を開閉させる。   In the modification shown in FIG. 10D, an inclined portion 48 is provided on the base 41d of the valve member 31d in place of the notch 43. In the valve member 31d of this modification, the intake valve body portion 53 of the film 51 moves up and down on the inclined portion 48 of the base 41d to open and close the intake valve 39.

以上の変形例に限らず、本発明の注出容器において、フィルム51の吸気弁体部53がキャップ61の吸気口64を開閉可能に上下動自在であり、吸気口64から流入した外気が外容器21の外気導入孔23へ流通可能であれば吸気弁39の形成方法は、特定の方法に限定されるものではない。   In addition to the above-described modifications, in the dispensing container of the present invention, the intake valve body 53 of the film 51 is movable up and down so that the intake port 64 of the cap 61 can be opened and closed, and the outside air flowing in from the intake port 64 is outside. The formation method of the intake valve 39 is not limited to a specific method as long as it can flow to the outside air introduction hole 23 of the container 21.

以上、第1から第4実施形態の注出容器1、2、3、4、及び変形例を用いて、本発明の弁部材及び該弁部材を備える注出容器を説明したが、本発明の弁部材及び該弁部材を備える注出容器は、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 mentioned above, although the extraction container provided with the valve member of this invention and this valve member was demonstrated using the extraction containers 1, 2, 3, 4, and modification of 1st to 4th embodiment, The valve member and the dispensing container including the valve member are not limited to the above-described embodiment, and can be used by being modified without changing the gist.

基台には、主に板材を用いたが、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、弁部材の被取付部と気密状態で接着可能であれば凹凸等が設けられていてもよい。   Although a 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. Moreover, the base does not need to be flat, and may be provided with irregularities or the like as long as it can be adhered to the attached portion of the valve member in an airtight state.

また基台の上面をドーム状に形成すると、フィルムに均一に張力を加えやすくなり、かつ張力がフィルムを基台に密着させる方向にも働くので、吐出弁38のシール性能が向上し、好ましい。   In addition, it is preferable to form the upper surface of the base in a dome shape because it is easy to apply a uniform tension to the film and the tension also works in the direction in which the film is brought into close contact with the base.

基台の弁座には、毛管吸引力を確実に働かせるための葉脈状の溝(図示省略)や全幅に亘って設けられる溝(図示省略)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38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。   A valve seat of the base may be provided with a vein-like groove (not shown) for ensuring the capillary suction force, a groove (not shown) provided over the entire width, or the like. By providing such a groove, the sealing performance of the discharge valve 38 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。   Further, 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 circle 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.

吸気流路9内の気密性は、前述したように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1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を防止すべく、吸気弁39やキャップ61の雌ネジ70と外容器21の雄ネジ24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 airtightness in the intake flow path 9 may be maintained as long as the contents can be discharged as described above. For example, the outer container 21 is unexpectedly pressurized when the dispensing container 1 falls. In order to prevent the contents from leaking out, air may be intentionally leaked somewhat from the gap between the female screw 70 of the intake valve 39 or the cap 61 and the male screw 24 of the outer container 21.

本発明の弁部材及び注出容器の材質は、用途、収容する内容物に応じて適宜選択して使用可能なことは既に記載した通りであるが、本発明の弁部材及び注出容器の形態が要旨を変更しない範囲で変更され、本発明の弁部材及び注出容器に他の部品が付加されたような場合でも、その部分の材質については、用途、収容する内容物に応じて適宜選択して使用すればよい。例えば、注出容器において収容する液体が酸化することを防止するには、液体と接する全ての部材(含む部品)、あるいは主要部材を酸素遮断性に優れる材質とすればよい。なお、使用する材料は、所定の性能を満たせば安価で入手し易いことが好ましいことは改めて言うまでもない。   As described above, the material of the valve member and the dispensing container of the present invention can be appropriately selected and used according to the intended use and contents to be contained. However, even if other parts are added to the valve member and the dispensing container of the present invention, the material of the part is appropriately selected according to the use and contents to be accommodated. And use it. For example, in order to prevent the liquid contained in the dispensing container from being oxidized, all members (including parts) in contact with the liquid or main members may be made of a material having excellent oxygen barrier properties. Needless to say, it is preferable that the material to be used is inexpensive and easily available as long as it satisfies a predetermined performance.

また上記実施形態では、弁部材を備える注出容器等を示したが、弁部材は、上記実施形態以外のもの、例えば、流体の排出と吸入とを必要とするような流路の途中、流路の端部、タンクの開口部等に取付けてもよく、容器、空隙、空洞、管内等の流体が滞留又は移動する空間において流体を隔てるように取付けて使用することができる。弁部材によって隔てられる流体のうち少なくとも一方が大気であってもよい。   Moreover, in the said embodiment, although the extraction container provided with a valve member etc. was shown, the valve member is other than the said embodiment, for example, in the middle of a flow path which requires discharge | emission and suction | inhalation of fluid, It may be attached to the end of the passage, the opening of the tank, or the like, and can be attached and used so as to separate the fluid in a space where the fluid stays or moves, such as a container, a void, a cavity, or a pipe. At least one of the fluids separated by the valve member may be the atmosphere.

以上のとおり、図面を参照しながら好適な実施形態を説明したが、当業者であれば、本明細書を見て、自明な範囲内で種々の変更及び修正を容易に想定するであろう。従って、そのような変更及び修正は、請求の範囲から定まる発明の範囲内のものと解釈される。   As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification. Therefore, such changes and modifications are interpreted as being within the scope of the invention defined by the claims.
