Description

本発明は、スパウト付き容器及び容器用スパウトに関する。 The present invention relates to a container with a spout and a spout for a container.

従来、スパウト付き容器が知られている。例えば、特許文献１には、プラスチック製の注出口部とフランジ部とが嵌合又は螺着により互いに分離可能に一体化されている口栓が取り付けられた口栓付き液体紙容器が開示されている。このようなスパウト付き容器が有するスパウト（口栓）を構成する材料としては、合成樹脂が一般的に用いられている。 Conventionally, a container with a spout is known. For example, Patent Document 1 discloses a liquid paper container with a spout to which a spout in which a plastic spout and a flange are detachably integrated by fitting or screwing is attached. There is. A synthetic resin is generally used as a material for forming the spout (plug) of such a container with a spout.

スパウト付き容器や容器用スパウトにおいては、省資源化、低コスト化等が望まれている。スパウト付き容器や容器用スパウトの省資源化や低コスト化を行うためには、スパウトを構成する樹脂として、リサイクル樹脂等を用いることが考えられる。しかし、一般に、リサイクル樹脂は、バージン樹脂に比してその品質が劣るため、容器の内容物に接触するスパウトをリサイクル樹脂により形成することが望ましくない場合がある。
特許文献１では、注出口部の内部に、液体内容物を注出するための孔設部が孔設されているため、注出口部をリサイクル樹脂により形成した場合、例えば、容器を輸送したり、店頭に展示したりしているときに、内容物が注出口部に触れて、内容物が汚染等されてしまう可能性がある。このように、スパウトを形成する樹脂として、リサイクル樹脂等の内容物に接触させたくない樹脂を用いることは困難であった。 In spout-equipped containers and container spouts, resource saving and cost reduction are desired. In order to save resources and reduce the cost of the spout-equipped container and the container spout, it is conceivable to use a recycled resin or the like as the resin forming the spout. However, since the quality of recycled resin is generally inferior to that of virgin resin, it may not be desirable to form the spout that comes into contact with the contents of the container with recycled resin.
In Patent Document 1, since a hole for pouring out the liquid content is formed inside the spout, if the spout is made of recycled resin, for example, a container may be transported. The contents may come into contact with the spout when the product is displayed in a store, and the contents may be contaminated. As described above, it is difficult to use a resin such as a recycled resin that is not desired to be brought into contact with the content as the resin forming the spout.

本発明の課題は、前述した従来技術が有する欠点を解消し得るスパウト付き容器及び容器用スパウトを提供することにある。 An object of the present invention is to provide a container with a spout and a spout for a container capable of solving the above-mentioned drawbacks of the conventional technique.

The tubular portion of the spout has an inner tubular portion made of a first resin, and an annular screw member made of a second resin fixed to an outer peripheral portion of the inner tubular portion. The mating member has a screw thread for screwing the cap on the outer peripheral portion, and when the cap is closed, the upper portion of the inner tubular portion and a part of the cap come into contact with each other, A spout-equipped container in which a gap for contacting the contents with the screw member is not formed between the inner cylindrical portion and the cap.

また本発明は、上端開口部を有する筒状部を備えた容器用スパウトであって、前記筒状部は、第１の樹脂からなる内筒部と、該内筒部の外周部に固定された、第２の樹脂からなる環状の螺合部材とを有し、該螺合部材は、外周部に前記キャップを螺合させるための螺条を有しており、前記内筒部の高さが、前記筒状部の高さの８０％以上１００％以下である、容器用スパウトを提供するものである。 The present invention also provides a container spout having a tubular portion having an upper end opening, the tubular portion being fixed to an inner tubular portion made of a first resin and an outer peripheral portion of the inner tubular portion. And an annular threaded member made of a second resin, the threaded member having a thread for screwing the cap on the outer peripheral portion, and the height of the inner cylindrical portion.

When a resin containing an additive for preventing oxidative deterioration and hue change of the resin is used as the second resin, oxidative deterioration and hue change of the screw member 5 can be prevented.

上述のような内容物に移行させたくない成分を含む樹脂に、内容物が接触した際には、該樹脂の色が内容物に移行してしまう等の不都合が生じてしまうが、本実施形態のスパウト付き容器１００によれば、内容物は、第２の樹脂からなる螺合部材５に接触しないようになっているため、第２の樹脂として内容物に移行させたくない成分を含む樹脂を使用した場合であっても、前記不都合を防ぐことが可能となる。
尚、「内容物に移行させたくない成分を含む樹脂」とは、内容物に移行させたくない成分を、実際に含んでいる樹脂のみならず、実際には、内容物に移行させたくない成分を含んでいないが、一般的には、内容物に移行させたくない成分を含んでいると考えられている樹脂を含む意味である。 As described above, when the content comes into contact with a resin containing a component that is not desired to be transferred to the content, the color of the resin may be transferred to the content. According to the spout-equipped container 100, since the content does not come into contact with the screwing member 5 made of the second resin, a resin containing a component which is not desired to be transferred to the content as the second resin is included. Even when used, it is possible to prevent the inconvenience.
The "resin containing a component that is not desired to be transferred to the contents" is not only a resin that actually contains a component that is not desired to be transferred to the contents, but is a component that is actually not desired to be transferred to the contents. However, it is generally meant to include a resin which is considered to contain a component which is not desired to be transferred to the contents.

キャップ３の外殻体３０を構成する第３の樹脂としては、第１の樹脂を構成する合成樹脂と同様の樹脂を用いることができる。本実施形態では、第３の樹脂は、内容物に移行させたくない成分を含む樹脂ではないことが好ましい。 As the third resin forming the outer shell body 30 of the cap 3, the same resin as the synthetic resin forming the first resin can be used. In the present embodiment, it is preferable that the third resin is not a resin containing a component that is not desired to be transferred to the contents.

容器用スパウト１は、内筒部４の上端４ａと螺合部材５の上端５ａとの軸方向Ｚの高さ位置が一致してもよいし、一致していなくてもよい。本実施形態では、図３及び図４に示すように、内筒部４の上端４ａと螺合部材５の上端５ａとの、軸方向Ｚの高さ位置は一致しており、内筒部４の上端面と螺合部材５の上端面とは面一となっており、内筒部４の上端４ａ及び螺合部材５の上端５ａが、筒状部１１の上端１１ａとなっている。
内筒部４の上端４ａと螺合部材５の上端５ａとの軸方向Ｚの高さ位置が一致していない場合は、図５に示すように、内筒部４の上部４２が螺合部材５の上端５ａよりも上方に延出して、内筒部４の上端４ａが螺合部材５の上端５ａよりも上方に位置していてもよい。このとき、内筒部４の上端４ａが、筒状部１１の上端１１ａとなる。 In the container spout 1, the height positions of the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 in the axial direction Z may or may not match. In the present embodiment, as shown in FIGS. 3 and 4, the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 have the same height position in the axial direction Z, and the inner tubular portion 4 And the upper end surface of the screwing member 5 are flush with each other, and the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 are the upper end 11a of the tubular portion 11.
When the height positions of the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 in the axial direction Z do not match, as shown in FIG. The upper end 4a of the inner tubular portion 4 may be located above the upper end 5a of the screwing member 5 so as to extend above the upper end 5a of the screw member 5. At this time, the upper end 4a of the inner tubular portion 4 becomes the upper end 11a of the tubular portion 11.

内筒部４の上端４ａと螺合部材５の上端５ａとの軸方向Ｚの高さ位置が一致しているか、又は内筒部４の上部４２が螺合部材５の上端５ａよりも上方に延出している場合、キャップ３を閉蓋したときに、内筒部４の上端４ａがキャップ３の天面部３１の内面３１ａに接触して、内筒部４とキャップ３との間に、内容物を螺合部材５に接触させる隙間が形成されないようになされる。これにより、内容物が螺合部材５に接触することを防ぐことができるため、螺合部材５を内容物に接触させたくない成分を含む樹脂により形成することが可能となる。 The height positions of the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 in the axial direction Z are the same, or the upper portion 42 of the inner tubular portion 4 is located above the upper end 5a of the screwing member 5. When the cap 3 is closed, the upper end 4a of the inner tubular portion 4 contacts the inner surface 31a of the top surface portion 31 of the cap 3 when the cap 3 is closed, so that the content between the inner tubular portion 4 and the cap 3 is increased. A gap for contacting an object with the screwing member 5 is not formed. This can prevent the contents from coming into contact with the screwing member 5, so that the screwing member 5 can be formed of a resin containing a component which is not desired to come into contact with the contents.

また、内筒部４の上端４ａと螺合部材５の上端５ａとの筒状部１１の軸方向Ｚの高さ位置が一致していない場合は、図６に示すように、螺合部材５の上部５３が内筒部４の上端４ａよりも上方に延出していてもよい。このとき、螺合部材５の上端５ａが、筒状部１１の上端１１ａとなる。螺合部材５の上部５３が内筒部４の上端４ａよりも上方に延出している場合、キャップ３は、図６（ｂ）に示すように、インナーリング３５を有していることが好ましい。図６（ｂ）に示すキャップ３は、天面部３１におけるスカート部３２から離間した位置に、天面部３１から垂下するように環状のインナーリング３５が形成されている。インナーリング３５は、キャップ３の閉蓋時に、内筒部４の上部４２の内周面に当接する。このように、図６に示す筒状部１１及びキャップ３においても、内筒部４とキャップ３との間に、内容物を螺合部材５に接触させる隙間が形成されないようになされている。 If the height positions of the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 in the axial direction Z of the tubular portion 11 do not match, as shown in FIG. The upper portion 53 of the above may extend above the upper end 4a of the inner tubular portion 4. At this time, the upper end 5a of the screwing member 5 becomes the upper end 11a of the tubular portion 11. When the upper portion 53 of the screw member 5 extends above the upper end 4a of the inner tubular portion 4, the cap 3 preferably has an inner ring 35 as shown in FIG. 6(b). .. In the cap 3 shown in FIG. 6B, an annular inner ring 35 is formed at a position separated from the skirt portion 32 on the top surface portion 31 so as to hang down from the top surface portion 31. The inner ring 35 contacts the inner peripheral surface of the upper portion 42 of the inner tubular portion 4 when the cap 3 is closed. As described above, also in the tubular portion 11 and the cap 3 shown in FIG. 6, no gap is formed between the inner tubular portion 4 and the cap 3 for contacting the contents with the screwing member 5.

内筒部４の高さＨ２は、内容物を螺合部材５に接触させる隙間が確実に形成されないようにする観点から、筒状部１１の高さＨ１の８０％以上であることが好ましく、９０％以上であることがより好ましく、９５％以上であることが更に好ましい。内筒部４の高さＨ２とは、固着部１９の上面１９ａから内筒部４の上端４ａまでの高さを意味し、筒状部１１の高さＨ１とは、固着部１９の上面１９ａから筒状部１１の上端１１ａまでの高さを意味する（図５（ａ）及び図６（ａ）参照）。内筒部４の上端４ａが筒状部１１の上端１１ａであるとき、内筒部４の高さＨ２と筒状部１１の高さＨ１とは一致するため、内筒部４の高さＨ２は、筒状部１１の高さＨ１の１００％となる。 The height H2 of the inner tubular portion 4 is preferably 80% or more of the height H1 of the tubular portion 11 from the viewpoint that a gap for contacting the contents with the screwing member 5 is not reliably formed, It is more preferably at least 90%, further preferably at least 95%. The height H2 of the inner tubular portion 4 means the height from the upper surface 19a of the fixed portion 19 to the upper end 4a of the inner tubular portion 4, and the height H1 of the tubular portion 11 means the upper surface 19a of the fixed portion 19. To the upper end 11a of the tubular portion 11 (see FIGS. 5A and 6A). When the upper end 4a of the inner tubular portion 4 is the upper end 11a of the tubular portion 11, the height H2 of the inner tubular portion 4 and the height H1 of the tubular portion 11 coincide with each other. Is 100% of the height H1 of the tubular portion 11.

図７に、本発明に係るキャップの変形例であるキャップ３Ｂを示す。図７には、キャップ３Ｂが筒状部１１に螺合されている状態の断面図が示されている。
キャップ３Ｂは、第３の樹脂からなる外殻体３０と、該外殻体３０の内側に配置された、該外殻体３０と異なる材料からなる封止部材６０とを有している。
封止部材６０は、該封止部材６０から垂下するように環状のインナーリング６５が形成されていてもよいし（図７（ｂ）参照）、形成されていなくてもよい（図７（ａ）参照）。図７（ｂ）に示すように、螺合部材５の上部５３が内筒部４の上端４ａよりも上方に延出している場合、封止部材６０にはインナーリング６５が形成されていることが好ましい。 FIG. 7 shows a cap 3B which is a modified example of the cap according to the present invention. FIG. 7 shows a sectional view of a state in which the cap 3B is screwed into the tubular portion 11.
The cap 3B has an outer shell body 30 made of a third resin, and a sealing member 60 arranged inside the outer shell body 30 and made of a material different from that of the outer shell body 30.
The sealing member 60 may be formed with an annular inner ring 65 so as to hang from the sealing member 60 (see FIG. 7B), or may not be formed (see FIG. 7A). )reference). As shown in FIG. 7B, when the upper portion 53 of the screwing member 5 extends above the upper end 4a of the inner tubular portion 4, an inner ring 65 is formed on the sealing member 60. Is preferred.

封止部材６０としては、ゴム製、シリコン製、エラストマー製、ポリエチレン製、発泡ポリエチレン製、ポリプロピレン製、発泡ポリプロピレン製等のパッキン等が挙げられる。封止部材６０は、発泡オレフィン樹脂にオレフィン樹脂シートをラミネートしたもの、発泡オレフィン樹脂にポリエステル樹脂シートをラミネートしたもの等であってもよい。 Examples of the sealing member 60 include packing made of rubber, silicon, elastomer, polyethylene, expanded polyethylene, polypropylene, expanded polypropylene, or the like. The sealing member 60 may be formed by laminating an olefin resin sheet on a foamed olefin resin, or by laminating a polyester resin sheet on a foamed olefin resin.

キャップ３Ｂを有するスパウト付き容器１００は、図７（ａ）及び（ｂ）に示すように、キャップ３Ｂを閉蓋したときに、内筒部４の上部４２と封止部材６０とが、内容物を螺合部材５に接触させる隙間を生じないように接触するようになっている。これにより、キャップ３を有するスパウト付き容器１００と同様の効果が奏される。
また、キャップ３Ｂを有するスパウト付き容器１００においては、キャップ３Ｂを閉蓋したときに、内容物がキャップ３Ｂを構成する外殻体３０に接触することも防ぐことができるため、外殻体３０を構成する第３の樹脂として、内容物に移行させたくない成分を含む樹脂を用いることができる。
図７（ａ）に示すキャップ３Ｂは、内筒部４の上端４ａと螺合部材５の上端５ａとの筒状部１１の軸方向Ｚの高さ位置が一致している容器用スパウト１に限らず、図５（ａ）に示すような、内筒部４の上端４ａが螺合部材５の上端５ａよりも上方に延出している容器用スパウト１と組み合わせて用いてもよい。 As shown in FIGS. 7A and 7B, when the cap 3B is closed, the spout-equipped container 100 having the cap 3B is configured such that the upper portion 42 of the inner tubular portion 4 and the sealing member 60 are Are in contact with each other so as not to create a gap for contacting with the screw member 5. Thereby, the same effect as that of the spout-equipped container 100 having the cap 3 is achieved.
Further, in the spout-equipped container 100 having the cap 3B, it is possible to prevent the contents from coming into contact with the outer shell body 30 forming the cap 3B when the cap 3B is closed. As the constituent third resin, a resin containing a component which is not desired to be transferred to the contents can be used.
The cap 3B shown in FIG. 7A corresponds to the container spout 1 in which the upper end 4a of the inner tubular portion 4 and the upper end 5a of the screwing member 5 have the same height in the axial direction Z of the tubular portion 11. Not limited to this, it may be used in combination with the container spout 1 in which the upper end 4a of the inner tubular portion 4 extends above the upper end 5a of the screwing member 5, as shown in FIG.

図８に、本発明に係るキャップの別の変形例であるキャップ３Ｃを示す。図８には、キャップ３Ｃの断面図が示されている。
キャップ３Ｃは、内周部に形成された螺条が間欠螺条３３Ｃとなっている。間欠螺条３３Ｃは、キャップ３Ｃの内周部に螺旋状に配された複数の凸部３８からなる。
キャップ３Ｃの間欠螺条３３Ｃを構成する樹脂は、螺合部材５の外周部に形成された螺条を構成する樹脂と同じ硬さであるか又は螺合部材５の外周部に形成された螺条を構成する樹脂よりも硬い。本実施形態では、キャップ３Ｃを構成する第３の樹脂が、螺合部材５を構成する第２の樹脂と同じ硬さであるか又は螺合部材５を構成する第２の樹脂よりも硬いことが好ましく、キャップ３Ｃを構成する第３の樹脂が、螺合部材５を構成する第２の樹脂よりも硬いことがより好ましい。具体的には、第３の樹脂としてバージン樹脂を用い、第２の樹脂としてリサイクル樹脂を用いることが好ましい。第２の樹脂及び第３の樹脂の硬さは、以下の方法により測定することができる。 FIG. 8 shows a cap 3C which is another modification of the cap according to the present invention. FIG. 8 shows a cross-sectional view of the cap 3C.
In the cap 3C, the thread formed on the inner peripheral portion is an intermittent thread 33C. The intermittent thread 33C includes a plurality of convex portions 38 spirally arranged on the inner peripheral portion of the cap 3C.
The resin forming the intermittent thread 33C of the cap 3C has the same hardness as the resin forming the thread formed on the outer peripheral portion of the screw member 5, or the screw formed on the outer peripheral portion of the screw member 5. Harder than the resin that makes up the strip. In the present embodiment, the third resin forming the cap 3C has the same hardness as the second resin forming the screwing member 5, or is harder than the second resin forming the screwing member 5. Is preferable, and it is more preferable that the third resin forming the cap 3C is harder than the second resin forming the screwing member 5. Specifically, it is preferable to use a virgin resin as the third resin and a recycled resin as the second resin. The hardness of the second resin and the third resin can be measured by the following method.

＜硬さの測定方法＞
樹脂の硬さの測定方法には種々あるが、歪―応力の相関についての硬さの指標として一般的には弾性率（ヤング率）を測定することが有効である。例えば、測定したい樹脂でダンベル試験片を作製し、それを用いて曲げ弾性率又は引っ張り弾性率の測定を行う。曲げ弾性率測定は、例えば、ＪＩＳＫ７１７１に規定される方法により行い、ダンベル試験片は、８０×１０×ｈ４ｍｍのものを用いる。引っ張り弾性率測定は、例えば、ＪＩＳＫ７１６１に規定される方法により行い、ダンベル試験片は、１Ａ形もしくは１B形を用いる。 <Method of measuring hardness>
Although there are various methods for measuring the hardness of the resin, it is generally effective to measure the elastic modulus (Young's modulus) as an index of the hardness for the strain-stress correlation. For example, a dumbbell test piece is prepared from the resin to be measured, and the bending elastic modulus or the tensile elastic modulus is measured using it. The flexural modulus is measured by, for example, the method specified in JIS K7171, and a dumbbell test piece having a size of 80×10×h4 mm is used. The tensile elastic modulus is measured by, for example, the method specified in JIS K7161, and the dumbbell test piece is a 1A type or a 1B type.

キャップ３Ｃを有するスパウト付き容器１００においても、キャップ３を有するスパウト付き容器１００と同様の効果が奏される。更に、キャップ３Ｃを有するスパウト付き容器１００は、キャップ３Ｃを閉蓋したときに、キャップ３Ｃの間欠螺条３３Ｃが螺合部材５の螺条５２に経時的に食い込むように、キャップ３Ｃと螺合部材５とが当接するため、キャップ３Ｃを閉蓋した後、時間経過に伴ってキャップ３Ｃの開けトルクが低下することを抑制することができる。 The spout-equipped container 100 having the cap 3C also exhibits the same effect as the spout-equipped container 100 having the cap 3. Further, the spout-equipped container 100 having the cap 3C is screwed with the cap 3C so that the intermittent screw 33C of the cap 3C bites into the screw 52 of the screw member 5 with time when the cap 3C is closed. Since the member 5 abuts, it is possible to prevent the opening torque of the cap 3C from decreasing with time after the cap 3C is closed.

本発明のスパウト付き容器の収容部に収容される内容物は、特に制限されないが、好ましくは液体である。液体の内容物としては、例えば、ミネラルウォーター、ジュース、茶類等の飲料の液体；シャンプー、コンディショナー、リンス等の液状のヘアケア剤、ボディソープやハンドソープ等の液体石鹸、衣類や食器用の液体洗剤、柔軟剤や漂白剤、バストイレや床洗浄用の液体洗浄剤、液状の化粧品、液状の医薬品等の非飲料の液体等が挙げられる。スパウト付き容器の収容部に収容される内容物は、液体のみならず、粉体、粒体、クリーム等の非液体であっても良い。
スパウト付き容器は、少なくとも水を収容して容器を室温で２４時間倒立状態に保持する評価試験を行ったときに、水である内容物の螺合部材への接触が認められないことが好ましい。 The contents contained in the container of the spout-equipped container of the present invention are not particularly limited, but are preferably liquid. Examples of the liquid content include liquids of beverages such as mineral water, juice and tea; liquid hair care agents such as shampoos, conditioners and rinses, liquid soaps such as body soaps and hand soaps, liquids for clothes and tableware. Examples thereof include detergents, softening agents and bleaching agents, liquid detergents for washing bathrooms and floors, liquid cosmetics, non-beverage liquids such as liquid pharmaceuticals, and the like. The contents stored in the storage portion of the spout-equipped container may be not only liquid but also non-liquid such as powder, granules and cream.
It is preferable that the spout-equipped container does not allow contact of the water content with the screwing member when an evaluation test is performed in which at least water is contained and the container is kept in an inverted state at room temperature for 24 hours.

上述した実施形態における容器本体２を形成する可撓性シートとしては、ポリオレフィン、ポリエステル、ポリアミド等の合成樹脂又はこれらの組み合わせからなる単層又は多層のフィルムや積層シート、又はこれらにアルミニウム等の金属蒸着層を付加した積層シート等が挙げられるが、これらに制限されるものではない。 As the flexible sheet forming the container body 2 in the above-described embodiment, a single-layer or multi-layer film or laminated sheet made of a synthetic resin such as polyolefin, polyester, polyamide or a combination thereof, or a metal such as aluminum Examples thereof include a laminated sheet having a vapor deposition layer added thereto, but are not limited thereto.

本発明の容器用スパウト及びスパウト付容器は、上述した実施形態に制限されず、適宜変更可能である。
例えば、内筒部４は、円筒状に代えて角筒状であってもよい。
また、本発明のスパウト付き容器は、容器本体とは別に製造した容器用スパウトを該容器本体に固着してなるものに限られず、例えば、内筒部及び固着部と容器本体部とが射出成形等の型成形等やブロー成形等により一体成形されたスパウト付き容器であっても良い。そのようなスパウト付き容器においても、内筒部の外周部に固定され、キャップと螺合するための螺条を有する環状の螺合部材を設け、キャップの閉蓋時に、内筒部の上部とキャップの一部とが接触して、該内筒部と該キャップとの間に、内容物を螺合部材に接触させる隙間が形成されないようにすることにより、前述したスパウト付容器１００と同様の効果が得られる。また本発明のスパウト付き容器は、射出成形やブロー成形等の任意の方法により製造した容器本体に、別に製造した筒状体を固定して内筒部としたものであっても良い。また、前述した容器用スパウト１の筒状部１１に関する構成や好ましい構成は、全部又は一部を、本発明のスパウト付き容器の筒状部に適用することもできる。 The spout for a container and the container with a spout of the present invention are not limited to the above-described embodiments, and can be appropriately changed.
For example, the inner tubular portion 4 may be a rectangular tubular shape instead of the cylindrical shape.
Further, the container with a spout of the present invention is not limited to one in which a container spout manufactured separately from the container body is fixed to the container body, and for example, the inner cylinder part and the fixing part and the container body part are injection molded. It may be a container with a spout that is integrally formed by die molding or the like, blow molding, or the like. Even in such a spout-equipped container, an annular screw member having a thread for screwing with the cap, which is fixed to the outer peripheral portion of the inner cylinder portion, is provided, and when the cap is closed, the upper portion of the inner cylinder portion is By not contacting a part of the cap and forming a gap between the inner cylindrical portion and the cap for contacting the contents with the screwing member, the same manner as the spout-equipped container 100 described above. The effect is obtained. Further, the spout-equipped container of the present invention may be one in which a separately manufactured cylindrical body is fixed to the container body manufactured by an arbitrary method such as injection molding or blow molding to form an inner cylindrical portion.
