　以下、本発明の実施形態について説明する。以下に示す実施形態中で示した各種特徴事項は、互いに組み合わせ可能である。また、各特徴について独立して発明が成立する。以下の説明中での上・下は、において、図１に示すように容器本体３を立設させた状態での上・下を意味する。 Hereinafter, embodiments of the present invention will be described. The various features shown in the embodiments described below can be combined with one another. In addition, the invention is established independently for each feature. Upper and lower in the following description mean upper and lower in a state where the container main body 3 is erected as shown in FIG.
１．第１実施形態
１－１．全体構成
　図１及び図２Ａに示すように、本発明の第１実施形態の積層剥離容器１は、キャップ２と、容器本体３と弁部材５を備える。容器本体３は、内容物を収容する収容部７と、収容部７から内容物を吐出する口部９を備える。キャップ２は、口部９に装着される。キャップ２は、ネジ式で装着するものであっても、打栓式で装着するものであってもよい。口部９には、キャップ２を装着するための係合部９ａが設けられている。内容物は、口部９の開口端９ｂから吐出される。 1. First Embodiment 1-1. Overall Configuration As shown in FIGS. 1 and 2A, the delamination container 1 according to the first embodiment of the present invention includes a cap 2, a container body 3 and a valve member 5. The container main body 3 includes an accommodating portion 7 for accommodating the contents, and a port 9 for discharging the contents from the accommodating portion 7. The cap 2 is attached to the mouth 9. The cap 2 may be attached by screwing or by tapping. The mouth 9 is provided with an engaging portion 9 a for mounting the cap 2. The contents are discharged from the open end 9 b of the mouth 9.
　図２に示すように、容器本体３は、収容部７及び口部９において、外殻１２と内袋１４を備える。内容物の減少に伴って内袋１４が外殻１２から剥離することによって、内袋１４が外殻１２から離れて収縮する。 As shown in FIG. 2, the container body 3 includes an outer shell 12 and an inner bag 14 in the housing portion 7 and the mouth portion 9. By the removal of the inner bag 14 from the outer shell 12 as the contents decrease, the inner bag 14 contracts away from the outer shell 12.
　弁部材５は、図２に示すように、収容部７に形成された外気導入孔１５に挿入され、外殻１２と内袋１４の間の空間Ｇと外部との間の空気の出入りを調節するためのものである。弁部材５の構成としては、例えば、外気導入孔１５の縁と弁部材５の間の隙間を弁部材５の移動によって開閉することによって、弁部材５が外気導入孔１５を開閉する構成や、弁部材５自体に貫通孔と開閉可能な弁を設けて、この弁の働きによって貫通孔を開閉することによって、外気導入孔１５を開閉する構成とすることができる。なお、弁部材５を設けず、外気導入孔１５にフィルタを貼り付けることで空気の出入りを調節する構成や、単に内容物を吐出する際に外気導入孔１５を指などで閉塞させて調整を行う構成とすることもできる。また、外気導入孔１５を口部９に設け、外気導入孔１５に連通する逆止弁を有するキャップを用いてもよい。 As shown in FIG. 2, the valve member 5 is inserted into the outside air introducing hole 15 formed in the housing portion 7, and regulates the flow of air between the space G between the outer shell 12 and the inner bag 14 and the outside. It is to do. As a configuration of the valve member 5, for example, a configuration in which the valve member 5 opens and closes the outside air introduction hole 15 by opening and closing the gap between the edge of the outside air introduction hole 15 and the valve member 5 by the movement of the valve member 5, A through hole and an openable / closable valve are provided in the valve member 5 itself, and the outside air introduction hole 15 can be opened and closed by opening and closing the through hole by the function of the valve. In addition, the valve member 5 is not provided, but the structure which adjusts inflow and outflow of air by affixing a filter in the external air introduction hole 15, or when simply discharging the contents is closed the external air introduction hole 15 with a finger etc. It can also be configured to perform. Alternatively, the outside air introduction hole 15 may be provided in the mouth 9 and a cap having a check valve communicating with the outside air introduction hole 15 may be used.
　弁部材５は、上記いずれの構成であっても、外殻１２を圧縮した際には外気導入孔１５を閉塞して内袋１４を圧縮可能な状態とし、外殻１２への圧縮力を解除すると空間Ｇ内に外気が導入されるよう構成される。 With any of the above-described configurations, the valve member 5 closes the outside air introduction hole 15 when the outer shell 12 is compressed to make the inner bag 14 compressible, thereby releasing the compression force applied to the outer shell 12 Then, the outside air is introduced into the space G.
　収容部７は、弁部材５を取り付けた後にシュリンクフィルムで覆われる。この際に、弁部材５がシュリンクフィルムに干渉しないように、弁部材５は、収容部７に設けられた弁部材取付凹部７ａに装着される。また、弁部材取付凹部７ａがシュリンクフィルムで密閉されてしまわないように弁部材取付凹部７ａから口部９の方向に延びる空気流通溝７ｂが設けられる（図１参照）。 The housing portion 7 is covered with a shrink film after the valve member 5 is attached. At this time, the valve member 5 is mounted in the valve member mounting recess 7 a provided in the housing portion 7 so that the valve member 5 does not interfere with the shrink film. Further, an air flow groove 7b extending in the direction from the valve member mounting recess 7a to the port 9 is provided so that the valve member mounting recess 7a is not sealed by the shrink film (see FIG. 1).
　また、容器本体３の層構成について、外殻１２は、復元性が高くなるように、内袋１４よりも肉厚に形成される。外殻１２は、例えば、低密度ポリエチレン、直鎖状低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン－プロピレン共重合体及びその混合物などで構成される。外殻１２は、複数層構成であってもよい。内袋１４は、複数の層から構成することが好ましい。例えば、外層と接触する層にエチレン－ビニルアルコール共重合体（ＥＶＯＨ）樹脂からなるＥＶＯＨ層を用い、内容物に接触する層に、例えば、低密度ポリエチレン、直鎖状低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン－プロピレン共重合体及びその混合物などのポリオレフィンからなる内面層を用いることができる。そして、上記ＥＶＯＨ層と内面層との間には、接着層を用いることが好ましい。 Further, regarding the layer configuration of the container main body 3, the outer shell 12 is formed thicker than the inner bag 14 so as to have high restorability. The outer shell 12 is made of, for example, low density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, ethylene-propylene copolymer and a mixture thereof. The outer shell 12 may have a multi-layer configuration. The inner bag 14 is preferably composed of a plurality of layers. For example, an EVOH layer composed of an ethylene-vinyl alcohol copolymer (EVOH) resin is used as a layer in contact with the outer layer, and low density polyethylene, linear low density polyethylene, high density polyethylene is used as a layer in contact with contents. An inner surface layer of polyolefin such as polypropylene, ethylene-propylene copolymer and mixtures thereof can be used. And, it is preferable to use an adhesive layer between the EVOH layer and the inner surface layer.
１－２．キャップ２の詳細構成
　次に、図２～図１１を用いて、キャップ２について説明する。キャップ２は、弁体２１と、中栓２２と、ノズル２３と、カバー２４を備える。 1-2. Detailed Configuration of Cap 2 Next, the cap 2 will be described with reference to FIG. 2 to FIG. The cap 2 includes a valve body 21, an inner plug 22, a nozzle 23, and a cover 24.
＜弁体２１＞
　図６に示すように、弁体２１は、流通孔２１ａと、環状部２１ｂと、椀状部２１ｃと、フランジ２１ｄと、連結部２１ｅを備える。弁体２１は、シリコーンゴムなどのエラストマーによって形成されており、内容物による内圧によって弾性変形する。 <Valve 21>
As shown in FIG. 6, the valve body 21 includes a flow hole 21a, an annular portion 21b, a flange portion 21c, a flange 21d, and a connecting portion 21e. The valve body 21 is formed of an elastomer such as silicone rubber, and is elastically deformed by the internal pressure of the contents.
　環状部２１ｂは、流通孔２１ａの周囲に設けられている。椀状部２１ｃは、椀状の部位であり、椀状部２１ｃの底２１ｃ１に流通孔２１ａが設けられている。フランジ２１ｄは、弁体２１の外周に設けられている。フランジ２１ｄと椀状部２１ｃの間に連結部２１ｅが設けられている。弁体２１に力が加わっていない状態では、図７Ｃに示すように、椀状部２１ｃの底２１ｃ１は平坦になっている。 The annular portion 21 b is provided around the flow hole 21 a. The bowl-shaped portion 21 c is a bowl-shaped portion, and the flow hole 21 a is provided in the bottom 21 c 1 of the bowl-shaped portion 21 c. The flange 21 d is provided on the outer periphery of the valve body 21. A connecting portion 21e is provided between the flange 21d and the hook portion 21c. When no force is applied to the valve body 21, as shown in FIG. 7C, the bottom 21c1 of the bowl-like portion 21c is flat.
＜中栓２２＞
　図７に示すように、中栓２２は、台座２２ａと、筒部２２ｂと、脚部２２ｃと、弁体支持部２２ｄと、係合部２２ｅを備える。中栓２２は、弁体２１よりも剛性が高い材料（ポリオレフィンなど）で形成されており、内容物による内圧によっては、実質的に変形しない。 <Inside plug 22>
As shown in FIG. 7, the inside plug 22 includes a base 22a, a cylinder 22b, a leg 22c, a valve body support 22d, and an engagement portion 22e. The inside plug 22 is formed of a material (such as polyolefin) that is more rigid than the valve body 21 and is not substantially deformed by the internal pressure of the contents.
　台座２２ａは、支柱状であり、流通孔２１ａよりも直径が大きく、上面２２ａ１が上側に凸の湾曲面になっている。内容物による内圧が環状部２１ｂに加わっていないときは、図４及び図９に示すように、流通孔２１ａの縁が台座２２ａに当接することによって流通孔２１ａが閉塞される。 The pedestal 22a is in the form of a support, and has a diameter larger than that of the flow through hole 21a, and the upper surface 22a1 is a curved surface convex upward. When the internal pressure due to the contents is not applied to the annular portion 21b, as shown in FIGS. 4 and 9, the edge of the through hole 21a abuts on the pedestal 22a, thereby closing the through hole 21a.
　弁体２１は、図９に示すように、底２１ｃ１が台座２２ａに押し付けられるように、中栓２２に装着される。この状態では、底２１ｃ１が台座２２ａに押し付けられることによって底２１ｃ１が台座２２ａの上面２２ａ１の湾曲面に沿った形状になるように弾性変形している。底２１ｃ１がこのように弾性変形することによって流通孔２１ａの縁と上面２２ａ１の間の密着性が高められている。また、台座２２ａの上面２２ａ１が湾曲面になっているために、上面２２ａ１が流通孔２１ａ内にわずかに入り込むことによって流通孔２１ａの縁と台座２２ａの密着度がさらに高められている。 The valve body 21 is mounted to the inside plug 22 so that the bottom 21c1 is pressed against the pedestal 22a, as shown in FIG. In this state, the bottom 21c1 is elastically deformed so that the bottom 21c1 conforms to the curved surface of the upper surface 22a1 of the pedestal 22a by pressing the bottom 21c1 against the pedestal 22a. By the elastic deformation of the bottom 21c1 in this manner, the adhesion between the edge of the flow hole 21a and the upper surface 22a1 is enhanced. Further, since the upper surface 22a1 of the pedestal 22a is a curved surface, the adhesion between the edge of the flow hole 21a and the pedestal 22a is further enhanced by the upper surface 22a1 slightly entering the flow passage 21a.
　筒部２２ｂと台座２２ａの間には、脚部２２ｃが設けられている。本実施形態では、複数（本実施形態では４本）の脚部２２ｃが等間隔（本実施形態では９０度間隔）で設けられている。台座２２ａは脚部２２ｃによって支持されている。台座２２ａは、筒部２２ｂと同軸上の位置に設けられており、脚部２２ｃは、筒部２２ｂの下端と台座２２ａの下部を連結するように設けられている。隣接する脚部２２ｃの間の隙間２２ｆを通じて内容物が流通可能になっている。隙間２２ｆを通じて内容物による内圧が環状部２１ｂに加えられる。 A leg 22c is provided between the cylindrical portion 22b and the pedestal 22a. In the present embodiment, a plurality of (four in the present embodiment) leg portions 22c are provided at equal intervals (in the present embodiment, at intervals of 90 degrees). The pedestal 22a is supported by the legs 22c. The pedestal 22a is provided coaxially with the cylindrical portion 22b, and the leg 22c is provided to connect the lower end of the cylindrical portion 22b and the lower portion of the pedestal 22a. The contents can be distributed through the gaps 22f between the adjacent legs 22c. The internal pressure due to the contents is applied to the annular portion 21b through the gap 22f.
　筒部２２ｂの内周面には弁体支持部２２ｄが設けられている。フランジ２１ｄが弁体支持部２２ｄ上に支持される。弁体支持部２２ｄは、径方向外側に向かって低くなる（開口端９ｂから離れる）傾斜面になっている。弁体２１のフランジ２１ｄは、弁体支持部２２ｄに対向する面が、弁体支持部２２ｄと同様に傾斜する傾斜面となっている。このような構成によって、弁体２１が弁体支持部２２ｄに安定して支持される。 A valve body support 22d is provided on the inner peripheral surface of the cylindrical portion 22b. The flange 21d is supported on the valve body support 22d. The valve body support 22d is an inclined surface which is lowered toward the radially outer side (away from the open end 9b). The flange 21 d of the valve body 21 is an inclined surface in which the surface facing the valve body support 22 d is inclined in the same manner as the valve body support 22 d. With such a configuration, the valve body 21 is stably supported by the valve body support 22 d.
　筒部２２ｂの外周面には、係合部２２ｅが設けられている。係合部２２ｅは、環状突起であり、中栓２２をノズル２３に係合させるために用いられる。 An engaging portion 22e is provided on the outer peripheral surface of the cylindrical portion 22b. The engaging portion 22 e is an annular protrusion and is used to engage the inside plug 22 with the nozzle 23.
＜ノズル２３＞
　図５Ａ及び図８に示すように、ノズル２３は、挿入筒部２３ａと、フランジ２３ｂと、吐出筒部２３ｃと、係止筒部２３ｄと、規制壁２３ｅと、吐出口２３ｆと、連結壁２３ｇと、係合部２３ｈ、流通孔２３ｉとを備える。 <Nozzle 23>
As shown in FIGS. 5A and 8, the nozzle 23 includes an insertion cylinder 23a, a flange 23b, a discharge cylinder 23c, a locking cylinder 23d, a regulating wall 23e, an outlet 23f, and a connecting wall 23g. , An engaging portion 23h, and a flow hole 23i.
　挿入筒部２３ａは、口部９内に挿入される。フランジ２３ｂは、挿入筒部２３ａの外周面に設けられており、口部９の開口端９ｂに当接される。挿入筒部２３ａ内に中栓２２が配置される。挿入筒部２３ａの内周面には係合部２３ｈが設けられている。係合部２３ｈは、環状突起で構成されている。中栓２２の係合部２２ｅが係合部２３ｈに係合されることによって中栓２２がノズル２３によって支持される。 The insertion tube 23 a is inserted into the mouth 9. The flange 23 b is provided on the outer peripheral surface of the insertion cylindrical portion 23 a and is in contact with the opening end 9 b of the port 9. The plug 22 is disposed in the insertion tube 23a. An engaging portion 23h is provided on the inner peripheral surface of the insertion cylindrical portion 23a. The engagement portion 23 h is configured by an annular protrusion. The plug 22 is supported by the nozzle 23 by the engagement portion 22e of the plug 22 being engaged with the engagement portion 23h.
　吐出筒部２３ｃは、連結壁２３ｇを介して挿入筒部２３ａに連結される。内容物は、吐出筒部２３ｃを通じて吐出される。規制壁２３ｅは、吐出筒部２３ｃ内に設けられており、規制壁２３ｅによって内容物の吐出の勢いが低減される。規制壁２３ｅは、吐出筒部２３ｃの内周面から突出するように設けられている。規制壁２３ｅは傾斜面２３ｅ１を有し、傾斜面２３ｅ１は、吐出筒部２３ｃの内周面から離れるにつれて吐出口２３ｆに近づくように傾斜する。規制壁２３ｅは、図８Ｂに示すように、平面視で、弁体２１の流通孔２１ａに重なるように設けられている。なお、本明細書において、「平面視で」とは、「平面図において」と言い換えることができ、別の表現では、「口部９の中心軸が延びる方向に見たときに」と言い換えることができる。図８に示すように、規制壁２３ｅは、流通孔２１ａと同心の円弧部２３ｅ２を有するように設けられている。このため、吐出筒部２３ｃの内面と規制壁２３ｅの間の流通孔２３ｉが扇形になっている。 The discharge cylindrical portion 23c is connected to the insertion cylindrical portion 23a via the connection wall 23g. The contents are discharged through the discharge cylinder 23c. The restriction wall 23e is provided in the discharge cylindrical portion 23c, and the momentum of the discharge of the contents is reduced by the restriction wall 23e. The restriction wall 23e is provided so as to protrude from the inner peripheral surface of the discharge cylindrical portion 23c. The restriction wall 23e has an inclined surface 23e1, and the inclined surface 23e1 is inclined so as to approach the discharge port 23f as it is separated from the inner peripheral surface of the discharge cylindrical portion 23c. The restriction wall 23e is provided so as to overlap the flow through hole 21a of the valve body 21 in a plan view, as shown in FIG. 8B. In the present specification, "in a plan view" can be reworded as "in a plan view", and in another expression it can be rephrased as "when viewed in the direction in which the central axis of the mouth 9 extends" Can. As shown in FIG. 8, the restriction wall 23 e is provided so as to have an arc portion 23 e 2 concentric with the flow hole 21 a. For this reason, the flow holes 23i between the inner surface of the discharge cylinder 23c and the restriction wall 23e are fan-shaped.
　係止筒部２３ｄは、挿入筒部２３ａの内側に設けられる。挿入筒部２３ａと係止筒部２３ｄの間に中栓２２の筒部２２ｂが配置される。係止筒部２３ｄは、弁体２１の開口端９ｂ側を係止するように構成されている。係止筒部２３ｄの先端２３ｄ１は、径方向外側に向かって高くなる傾斜面になっている。フランジ２１ｄは、先端２３ｄ１に対向する面が、先端２３ｄ１と同様に傾斜する傾斜面となっている。このような構成では、フランジ２１ｄを挟む部材（弁体支持部２２ｄ，先端２３ｄ１）の間の距離が径方向内側に向かって狭まるので、弁体２１が弁体支持部２２ｄと先端２３ｄ１の間に安定して支持される。 The locking cylinder 23 d is provided inside the insertion cylinder 23 a. The cylindrical portion 22b of the inner plug 22 is disposed between the insertion cylindrical portion 23a and the locking cylindrical portion 23d. The locking cylindrical portion 23 d is configured to lock the opening end 9 b side of the valve body 21. The tip end 23d1 of the locking cylindrical portion 23d is an inclined surface which is higher toward the radial outside. The flange 21 d is an inclined surface in which the surface facing the tip 23 d 1 is inclined in the same manner as the tip 23 d 1. In such a configuration, the distance between the members sandwiching the flange 21d (the valve body support 22d and the tip 23d1) narrows inward in the radial direction, so the valve body 21 is between the valve body support 22d and the tip 23d1. It is supported stably.

１－３．キャップ２の動作
　次に、本実施形態に係るキャップ２の動作を説明する。 1-3. Operation of Cap 2 Next, the operation of the cap 2 according to the present embodiment will be described.
　収容部７に外力が加わっていないときは、内容物による内圧が環状部２１ｂに加わらないので、図９に示すように、流通孔２１ａの縁が台座２２ａに当接することによって流通孔２１ａが閉塞される。 When no external force is applied to the housing portion 7, the internal pressure by the contents is not applied to the annular portion 21b, and as shown in FIG. 9, the edge of the flow hole 21a abuts on the pedestal 22a to close the flow hole 21a. Be done.
　収容部７に圧縮力を加えると、内容物による内圧が環状部２１ｂに加わることによって弁体２１が弾性変形し、これによって流通孔２１ａの縁が台座２２ａから離れて流通孔２１ａが開かれる。 When a compressive force is applied to the housing portion 7, the internal pressure of the contents is applied to the annular portion 21b to elastically deform the valve body 21, whereby the edge of the through hole 21a is separated from the pedestal 22a and the through hole 21a is opened.
　圧縮力が小さい場合には、弁体２１は、図１０に示すように、椀状部２１ｃの底２１ｃ１が浮き上がるように弾性変形する。この時点でも流通孔２１ａの縁が台座２２ａから離れて流通孔２１ａが開かれている。このように、弁体２１と台座２２ａで構成される逆止弁は、弁体２１が台座２２ａからわずかに離れるだけで開かれるので、容器を軽く圧縮しただけで内容物を吐出することができる。 When the compression force is small, as shown in FIG. 10, the valve body 21 elastically deforms so that the bottom 21c1 of the bowl-like portion 21c is lifted. Even at this time, the edge of the flow hole 21a is separated from the pedestal 22a, and the flow hole 21a is opened. Thus, the check valve formed by the valve body 21 and the pedestal 22a is opened only when the valve body 21 is slightly separated from the pedestal 22a, so that the contents can be discharged only by lightly compressing the container .
　収容部７に対して、より大きな圧縮力を加えると、弁体２１は、図１１に示すように、椀状部２１ｃが反転するように弾性変形する。規制壁２３ｅは、椀状部２１ｃがこのように変形したときでも椀状部２１ｃが接触しない位置に設けられている。このため、規制壁２３ｅによって椀状部２１ｃの変形が妨げられることがない。 When a larger compressive force is applied to the housing portion 7, the valve body 21 elastically deforms so that the collar portion 21c is inverted as shown in FIG. The restricting wall 23e is provided at a position where the hooked portion 21c does not contact even when the hooked portion 21c is deformed in this manner. Therefore, the restriction wall 23e does not prevent the deformation of the hook portion 21c.
　流通孔２１ａが開かれると、内容物は流通孔２１ａを通じて吐出筒部２３ｃに向かって流出し、規制壁２３ｅによって勢いが低減された後に吐出口２３ｆから吐出される。 When the flow hole 21a is opened, the contents flow out toward the discharge cylindrical portion 23c through the flow hole 21a, and after the force is reduced by the restriction wall 23e, the content is discharged from the discharge port 23f.
　収容部７への圧縮力が除かれると、弁体２１の復元力によって椀状部２１ｃが元の形状に復帰して、流通孔２１ａの縁が台座２２ａに当接することによって流通孔２１ａが再度、閉塞される。椀状部２１ｃは、圧縮力が除去された時点からわずかに遅れて元の形状に復帰する。この時間差の間に液の流れによって台座２２ａから固形物が除去されるので、流通孔２１ａの縁と台座２２ａの間に固形物が挟まる虞が低減される。 When the compression force to the housing portion 7 is removed, the restoring force of the valve body 21 restores the flange 21c to its original shape, and the edge of the flow hole 21a abuts on the pedestal 22a, so that the flow hole 21a is made again. , Blocked. The bowl-shaped portion 21c returns to its original shape slightly behind the point when the compression force is removed. Since the solid matter is removed from the pedestal 22a by the flow of the liquid during this time difference, the possibility of the solid matter being pinched between the edge of the flow hole 21a and the pedestal 22a is reduced.
１－４．従来技術との対比
　特許文献１のスリット弁では、サイズの大きな固形物の場合は、スリットに挟まりやすいが、本実施形態の構成の逆止弁では、流通孔２１ａの縁と台座２２ａの間隔を十分に大きくできるので、サイズの大きな固形物も挟まりにくい。 1-4. Comparison with the prior art In the slit valve of Patent Document 1, in the case of a solid having a large size, it is easy to get caught in the slit, but in the check valve of the configuration of this embodiment, the distance between the edge of the flow hole 21a and the pedestal 22a Because they can be large enough, large solid objects are not easily caught.
　さらに、特許文献１のスリット弁では、スリットは吐出弁の厚さ方向の全体に渡って設けられているので、スリット内の対向面が面当たり（面と面の接触）であるが、本実施形態の構成の逆止弁では、流通孔２１ａの縁と台座２２ａの接触面積を低減させることによって線当たり（線と線の接触）に近づけることが容易である。流通孔２１ａの縁と台座２２ａの接触面積を低減させる程、固形物が挟まりにくくなる。 Furthermore, in the slit valve of Patent Document 1, since the slit is provided over the entire thickness direction of the discharge valve, the opposing surface in the slit is a surface contact (surface to surface contact), but this embodiment In the non-return valve of the form of a structure, it is easy to approach line contact (line and line contact) by reducing the contact area of the edge of the through-hole 21a, and the base 22a. As the contact area between the edge of the flow hole 21a and the pedestal 22a is reduced, the solid matter is less likely to be caught.
　さらに、特許文献１のスリット弁は、弁の成形後に、スリットを刃物加工することが必須であり、その分だけ製造コストが高くなるが、本実施形態の弁体２１は、成形時に流通孔を形成することが可能であるので、成形後の刃物加工が不要であり、製造コストが抑制可能である。 Furthermore, in the slit valve of Patent Document 1, it is essential to machine the slit after molding of the valve, and the manufacturing cost is increased accordingly, but the valve body 21 of this embodiment has the through hole at the time of molding. As it is possible to form, it is not necessary to process the blade after molding, and the manufacturing cost can be suppressed.
　また、環状弁座とその中央に設けられた円形の弁体で構成されるような逆止弁では、内容物からの圧力が弁体に偏って加わった場合には、弁体が傾斜したりして、内容物の吐出が安定しない場合があるが、本実施形態の構成の逆止弁では、内容物による内圧が環状部２１ｂに加わって、環状部２１ｂの全体が持ち上がるように弾性変形するので、弁体２１が傾斜しにくく内容物の吐出が安定しやすい。 In addition, in a check valve composed of an annular valve seat and a circular valve body provided at the center thereof, when the pressure from the contents is biased to the valve body, the valve body is inclined or Although the discharge of the contents may not be stable, in the check valve of the configuration of the present embodiment, the internal pressure due to the contents is applied to the annular portion 21b, so that the entire annular portion 21b is elastically deformed to be lifted. Therefore, it is difficult for the valve body 21 to be inclined and the discharge of the contents is easily stabilized.
２．第２実施形態
　図１２を用いて、本発明の第２実施形態について説明する。本実施形態は、第１実施形態と類似しており、ノズル２３の吐出口２３ｆ及び吐出筒部２３ｃの構成の違いが主な相違点である。以下、相違点を中心に説明する。 2. Second Embodiment A second embodiment of the present invention will be described with reference to FIG. The present embodiment is similar to the first embodiment, and the difference in the configuration of the discharge port 23f of the nozzle 23 and the discharge cylindrical portion 23c is the main difference. The differences will be mainly described below.
　本実施形態では、ノズル２３は、吐出口２３ｆの位置が偏心されている。このため、図１２Ｂに示すように、平面視で、吐出口２３ｆと流通孔２１ａが同心になっていない。そして、吐出筒部２３ｃには、吐出口２３ｆに近づくにつれて吐出筒部２３ｃが縮径されるように傾斜する規制壁２３ｃ１が設けられている。規制壁２３ｃ１は、平面視で流通孔２１ａに重なっており、第１実施形態の規制壁２３ｅと同様に、内容物の吐出の勢いを低減させる。 In the present embodiment, the nozzle 23 is eccentric at the position of the discharge port 23 f. Therefore, as shown in FIG. 12B, the discharge port 23f and the flow hole 21a are not concentric with each other in plan view. The discharge cylinder portion 23c is provided with a regulating wall 23c1 which is inclined so that the diameter of the discharge cylinder portion 23c decreases as the discharge port 23f is approached. The restriction wall 23c1 overlaps the flow through hole 21a in a plan view, and reduces the momentum of the discharge of the contents, as in the case of the restriction wall 23e of the first embodiment.
３．第３実施形態
　図１３を用いて、本発明の第３実施形態について説明する。本実施形態は、第１実施形態と類似しており、ノズル２３の吐出口２３ｆ及び吐出筒部２３ｃの構成の違いが主な相違点である。以下、相違点を中心に説明する。 3. Third Embodiment The third embodiment of the present invention will be described with reference to FIG. The present embodiment is similar to the first embodiment, and the difference in the configuration of the discharge port 23f of the nozzle 23 and the discharge cylindrical portion 23c is the main difference. The differences will be mainly described below.
　本実施形態では、ノズル２３は、吐出口２３ｆの位置が偏心されていない。このため、図１３Ｂに示すように、平面視で、吐出口２３ｆと流通孔２１ａが同心になっている。吐出筒部２３ｃは、吐出口２３ｆに近づくにつれて縮径される縮径部２３ｃ２と、吐出口２３ｆに近づくにつれて直径が変化しない一定径部２３ｃ３を備える。 In the present embodiment, the nozzle 23 is not eccentric at the position of the discharge port 23 f. Therefore, as shown in FIG. 13B, the discharge port 23f and the flow hole 21a are concentric with each other in plan view. The discharge cylindrical portion 23c includes a reduced diameter portion 23c2 whose diameter decreases as it approaches the discharge port 23f, and a constant diameter portion 23c3 whose diameter does not change as it approaches the discharge port 23f.
　ノズル２３内には、ノズル２３の内面から突出する複数の（本実施形態では３つの）アーム２３ｊが設けられている。複数のアーム２３ｊは、周方向に等間隔になるように設けられている。各アーム２３ｊは、縮径部２３ｃ２と一定径部２３ｃ３の境界近傍から容器内部に向かって斜め方向に突出するように設けられている。 In the nozzle 23, a plurality of (three in the present embodiment) arms 23j protruding from the inner surface of the nozzle 23 are provided. The plurality of arms 23 j are provided at equal intervals in the circumferential direction. Each arm 23 j is provided so as to obliquely project toward the inside of the container from the vicinity of the boundary between the reduced diameter portion 23 c 2 and the constant diameter portion 23 c 3.
　規制壁２３ｋは、複数のアーム２３ｊによって支持されている。規制壁２３ｋは、図１３Ｂに示すように、平面視で流通孔２１ａと同心になって重なっており、第１実施形態の規制壁２３ｅと同様に、内容物の吐出の勢いを低減させる。内容物は、隣接するアーム２３ｊの間の流通孔２３ｌを通じて吐出される。本実施形態では、複数の流通孔２３ｌが周方向に等間隔で設けられている。 The restriction wall 23k is supported by a plurality of arms 23j. As illustrated in FIG. 13B, the restriction wall 23k is concentrically overlapped with the flow through hole 21a in plan view, and reduces the momentum of the discharge of the contents, similarly to the restriction wall 23e of the first embodiment. The contents are discharged through the flow holes 23l between the adjacent arms 23j. In the present embodiment, a plurality of flow holes 23 l are provided at equal intervals in the circumferential direction.
　本実施形態では、規制壁２３ｋが流通孔２１ａと同心になっており、且つ複数の流通孔２３ｌが周方向に等間隔に設けられているので、容器の周方向の向きを気にせずに内容物を吐出させることができる。このように、本実施形態のノズル２３は、周方向の方向性がないので、上蓋を装着する場合に、ノズル２３に対して上蓋を周方向に位置決めする必要がない。このため、上蓋がねじ式で装着するものであっても問題がない。 In the present embodiment, the restriction wall 23k is concentric with the flow hole 21a, and the flow holes 23l are provided at equal intervals in the circumferential direction. Therefore, the content of the container is not considered regardless of the circumferential direction of the container. An object can be discharged. As described above, since the nozzle 23 of the present embodiment has no circumferential directionality, there is no need to position the upper lid in the circumferential direction with respect to the nozzle 23 when mounting the upper lid. For this reason, there is no problem even if the upper lid is attached by screwing.
　また、規制壁２３ｋが吐出口２３ｆから離れた位置に設けられているので、内容物が規制壁２３ｋ上に残留しても外部から視認しにくい。 Further, since the restriction wall 23k is provided at a position away from the discharge port 23f, even if the contents remain on the restriction wall 23k, it is difficult to visually recognize from the outside.
　本実施形態のノズル２３を装着した積層剥離容器１から内容物２５を吐出する状態を図１５Ａに示す。内容物２５は、規制壁２３ｋに衝突した後に規制壁２３ｋを回り込むように流れて吐出口２３ｆから排出される。本実施形態では、吐出口２３ｆが偏心されておらず、かつ吐出口２３ｆの径が大きいので、吐出口２３ｆを通る内容物２５の流れが速く、吐出口２３ｆと流通孔２１ａの間の空間２３ｍは、通常は、内容物２５によって充填されることがない。このため、吐出後に流通孔２１ａを通じて内袋１４内に外気が侵入する現象（以下、「エアバック」）が起こりやすいという課題がある。このような課題は、第４実施形態によって解決される。 The state which discharges the content 25 from the lamination | stacking peeling container 1 with which the nozzle 23 of this embodiment was mounted | worn is shown to FIG. 15A. After colliding with the restricting wall 23k, the contents 25 flow around the restricting wall 23k and are discharged from the discharge port 23f. In this embodiment, since the discharge port 23f is not eccentric and the diameter of the discharge port 23f is large, the flow of the contents 25 passing through the discharge port 23f is fast, and the space 23m between the discharge port 23f and the flow hole 21a Is usually not filled by the contents 25. For this reason, there is a problem that the phenomenon that the outside air intrudes into the inside of the inner bag 14 through the flow holes 21a after discharge (hereinafter, "air bag") is likely to occur. Such a problem is solved by the fourth embodiment.
４．第４実施形態
　図１４を用いて、本発明の第４実施形態について説明する。本実施形態は、第１実施形態と類似しており、ノズル２３の吐出口２３ｆ及び吐出筒部２３ｃの構成の違いが主な相違点である。以下、相違点を中心に説明する。 4. Fourth Embodiment A fourth embodiment of the present invention will be described with reference to FIG. The present embodiment is similar to the first embodiment, and the difference in the configuration of the discharge port 23f of the nozzle 23 and the discharge cylindrical portion 23c is the main difference. The differences will be mainly described below.
　本実施形態では、ノズル２３の吐出筒部２３ｃは、本体筒部２３ｃ４と、縮径筒部２３ｃ５を有する。縮径筒部２３ｃ５は、円筒状であり、本体筒部２３ｃ４よりも断面積が小さい。縮径筒部２３ｃ５は、本体筒部２３ｃ４の天面部２３ｃ６において、偏心された位置に設けられており、本体筒部２３ｃ４と連通している。縮径筒部２３ｃ５の先端に吐出口２３ｆが設けられている。図１４Ｂに示すように、吐出口２３ｆが平面視で流通孔２１ａに重ならないように配置されている。 In the present embodiment, the discharge cylindrical portion 23c of the nozzle 23 has a main body cylindrical portion 23c4 and a reduced diameter cylindrical portion 23c5. The reduced diameter cylindrical portion 23c5 has a cylindrical shape, and has a smaller cross-sectional area than the main body cylindrical portion 23c4. The reduced diameter cylindrical portion 23c5 is provided at an eccentric position on the top surface portion 23c6 of the main body cylindrical portion 23c4, and communicates with the main body cylindrical portion 23c4. A discharge port 23f is provided at the tip of the reduced diameter cylindrical portion 23c5. As shown in FIG. 14B, the discharge port 23f is disposed so as not to overlap the flow through hole 21a in plan view.
　天面部２３ｃ６は、平面視で流通孔２１ａに重なっているため、流通孔２１ａを通過した内容物は、天面部２３ｃ６の内面に衝突し、吐出の勢いが低減される。このため、天面部２３ｃ６が規制壁として機能している。また、天面部２３ｃ６の内面が上に向かって凸になるように湾曲しているので、天面部２３ｃ６の内面に衝突した内容物が吐出口２３ｆに導かれにくくなっている。このため、図１５Ｂに示すように、吐出口２３ｆと流通孔２１ａの間の空間２３ｍが内容物２５で満たされやすくなる。 Since the top surface portion 23c6 overlaps the flow through hole 21a in plan view, the content passing through the flow through hole 21a collides with the inner surface of the top surface portion 23c6, and the momentum of the discharge is reduced. For this reason, the top surface portion 23c6 functions as a restriction wall. Further, since the inner surface of the top surface portion 23c6 is curved so as to be convex upward, the contents colliding with the inner surface of the top surface portion 23c6 are difficult to be led to the discharge port 23f. Therefore, as shown in FIG. 15B, the space 23m between the discharge port 23f and the flow hole 21a is easily filled with the content 25.
　また、本実施形態の吐出口２３ｆは、上述した実施形態に比べて細径になっているために、吐出口２３ｆを通る内容物２５の流れが遅い。このため、空間２３ｍがより内容物２５で一層満たされやすくなっている。平面視での、流通孔２１ａの開口面積をＳ１とし、吐出口２３ｆの開口面積をＳ２とすると、Ｓ２／Ｓ１≦５であることが好ましい。Ｓ２／Ｓ１は、例えば０．２～５であり、具体的には例えば、０．２、０．５、１、１．５、２、２．５、３、３．５、４、４．５、５であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。 Moreover, since the discharge port 23f of the present embodiment has a smaller diameter than the above-described embodiment, the flow of the contents 25 passing through the discharge port 23f is slow. Therefore, the space 23 m is more easily filled with the content 25. Assuming that the opening area of the flow hole 21a is S1 and the opening area of the discharge port 23f is S2 in plan view, it is preferable that S2 / S1 ≦ 5. S2 / S1 is, for example, 0.2 to 5, and specifically, for example, 0.2, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4. 5 and 5, and may be in the range between any two of the numerical values exemplified here.
　このように、本実施形態では、空間２３ｍが内容物２５で満たされやすくなっており、空間２３ｍが内容物２５で満たされることによってエアバックが抑制可能になっている。 As described above, in the present embodiment, the space 23 m is easily filled with the content 25, and the air bag can be suppressed by the space 23 m being filled with the content 25.
５．その他上記実施形態
　本発明は、以下の態様でも実施可能である。
・本発明のキャップ２は、積層剥離容器１以外の容器、例えば、単層の容器であって、内容物の吐出に伴って容器全体が収縮するものに用いることも可能である。 5. Other Embodiments Above The present invention can also be practiced in the following modes.
