Description

本発明は、粘性の高い流動物を収容する収容体に関する。   The present invention relates to a container that contains a highly viscous fluid.

従来、例えば、特許文献１に開示されているように、印刷用のインキのような粘性が高い流動物（以下、収容物と称する）を収容可能な収容体が知られている。このような収容体は、いわゆるバックインボックスタイプと称され、プリンタのような外部装置の所定位置に装填されるようになっており、収容物は、外部装置に設けられた吸引機構によって注出されて所定の位置に供給される。具体的に、特許文献１に開示された収容体は、薄膜状の樹脂フィルムによって袋状に形成された容器本体と、この容器本体の内部に封入され、容器本体を箱型に保形すると共に、容器本体から突出する注出口を有する支持部材とを備えた構成となっている。   2. Description of the Related Art Conventionally, as disclosed in, for example, Patent Document 1, a container that can store a fluid (hereinafter referred to as a container) having a high viscosity such as printing ink is known. Such a container is called a so-called back-in-box type, and is loaded into a predetermined position of an external device such as a printer, and the container is poured out by a suction mechanism provided in the external device. And supplied to a predetermined position. Specifically, the container disclosed in Patent Document 1 includes a container body formed in a bag shape with a thin-film resin film, and enclosed in the container body, and the container body is shaped like a box. And a support member having a spout protruding from the container main body.

そして、上記した構成において、注出口からポンプなどで吸引を行うと、薄膜状の樹脂フィルムは、収容物の流出に伴って支持部材の内部へまくれかえるように反転し、収容物が注出し終わると、樹脂フィルムは、支持部材の内部に入り込んだ状態に変化する。   In the configuration described above, when suction is performed from the spout with a pump or the like, the thin film-like resin film is inverted so as to be turned back into the support member with the outflow of the contents, and the contents are completely poured out. Then, the resin film changes into a state of entering the inside of the support member.

特開２００１−１９９４５５号JP 2001-199455 A

上記した収容体は、樹脂フィルムによって形成された容器本体の内側に支持部材を封入する構造であり、かつ、支持部材は、容器本体を所定の形状に保形させることから製造工程が複雑化し、コストが高くなってしまう。   The container described above has a structure in which a support member is enclosed inside the container main body formed of a resin film, and the support member is complicated in manufacturing process because the container main body is held in a predetermined shape. Cost becomes high.

また、上記した収容体は、支持部材の表面と容器本体が広く密着する構造であるため、容器本体に皺が入る等、両者の密着性が不十分となり易く、これにより、吸引時に、両者の隙間（支持部材の外面側）に収容物が残留してしまい、収容物に無駄が生じる可能性がある。また、樹脂フィルムによって形成される容器本体については、保形性を考慮して箱型となる構造（有底構造）となっているが、このような形状では、吸引時に支持部材の内部に入り込んでも、最終的に支持部材の内面との密着性に劣ってしまい、この結果、支持部材の内面側においても収容物が残留し易くなってしまう。   Further, since the container described above has a structure in which the surface of the support member and the container body are in close contact with each other, the adhesiveness between the two tends to be insufficient, such as wrinkles entering the container body. The stored item remains in the gap (the outer surface side of the support member), and the stored item may be wasted. In addition, the container body formed of a resin film has a box-shaped structure (bottomed structure) in consideration of shape retention, but in such a shape, it enters the inside of the support member during suction. However, the adhesiveness with the inner surface of the support member is ultimately inferior, and as a result, the contents are likely to remain on the inner surface side of the support member.

本発明は、上記した問題に着目してなされたものであり、製造コストが安価で、収容物を可能な限り無駄なく注出することが可能な収容体を提供することを目的とする。   The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a container that can be poured out as much as possible without waste and at a low manufacturing cost.

上記した目的を達成するために、本発明に係る収容体は、一端側の中央領域に収容物を吸引可能な注出口を有すると共に、前記注出口に向けて漏斗状に縮径する湾曲部を有する樹脂成型された円筒形状の円筒収容部と、前記円筒収容部の他端側の円形開口に沿って溶着されると共に、前記注出口からの吸引時に前記円筒収容部内に入り込んで内面に密着可能な薄膜フィルムによって、底縁と横縁を具備する非自立体となる袋状に形成された袋状収容部と、を有し、前記袋状収容部は、前記円筒収容部の長手方向の収容長さＬに対して９０％から１１０％の範囲の長さＬ１を有し、溶着部と反対となる端部側の前記底縁と横縁との間の隅部を切り欠いたことを特徴とする。 To achieve the above object, container according to the present invention, the curved portion of reduced diameter and has a spout that can suck the contained object in a central region of a single end side, the funnel-shaped towards the spout And a resin-molded cylindrical housing having a cylindrical shape, and welded along a circular opening on the other end side of the cylindrical housing, and enters the cylindrical housing when adhering from the spout and adheres closely to the inner surface A bag-shaped storage portion formed into a non-self-contained bag shape having a bottom edge and a lateral edge by a possible thin film, and the bag-shaped storage portion is arranged in the longitudinal direction of the cylindrical storage portion. The length L1 is in the range of 90% to 110% with respect to the accommodation length L , and the corner between the bottom edge and the lateral edge on the side opposite to the welded part is cut out. Features.

上記した構造の収容体は、注出口を有する樹脂成型された円筒収容部に対し、非自立体となる袋状に形成された袋状収容部を、円筒収容部の他端側の円形開口に沿って溶着した構造であるため、構造がシンプルとなり、かつ容易に製造できるため、コストの低減が図れるようになる。また、収容体は、その基本部分が円筒形状であるため、収容物の吸引時に、収容物が残留し難くなり、かつ、袋状収容部についても、非自立体で溶着部と反対となる端部側の隅部を切り欠いているため、収容物が残留し難くなる。さらに、袋状収容部は、円筒収容部の長手方向の収容長さに対して９０％から１１０％の範囲の長さとなっているため、吸引時に円筒収容部の内部に反転して引き込まれた際、その底縁領域を注出口部分の近辺に位置させることができ、これにより、効率的に収容物を注出することが可能となる。   The container having the above structure has a bag-shaped container formed in a non-self-contained bag shape in a circular opening on the other end side of the cylindrical container with respect to the resin-molded cylindrical container having a spout. Since the structure is welded along, the structure becomes simple and can be easily manufactured, so that the cost can be reduced. In addition, since the basic portion of the container is cylindrical, the container is difficult to remain during suction of the container, and the bag-shaped container also has a non-stereoscopic end opposite to the welded part. Since the corner on the part side is notched, the contents are less likely to remain. Furthermore, since the bag-shaped storage portion has a length in the range of 90% to 110% with respect to the storage length in the longitudinal direction of the cylindrical storage portion, it is reversed and drawn into the cylindrical storage portion during suction. At that time, the bottom edge region can be positioned in the vicinity of the spout portion, and thus, the contained item can be poured out efficiently.

本発明によれば、製造コストが安価で、収容物を可能な限り無駄なく注出することが可能な収容体が得られる。   According to the present invention, it is possible to obtain a container that is inexpensive to manufacture and can dispense the stored material as efficiently as possible.

図１及び図２は、本発明に係る収容体の一実施形態を示す図であり、図１（ａ）は斜視図、図１（ｂ）は正面図、図２（ａ）は図１に示す円筒収容部の構成を示す図である。また、図２（ｂ）及び（ｃ）は、それぞれ円筒収容部の変形例を示す図である。   1 and 2 are views showing an embodiment of a container according to the present invention. FIG. 1 (a) is a perspective view, FIG. 1 (b) is a front view, and FIG. 2 (a) is FIG. It is a figure which shows the structure of the cylindrical accommodating part shown. Moreover, FIG.2 (b) and (c) are figures which show the modification of a cylindrical accommodating part, respectively.

本実施形態に係る収容体１は、インクなど粘性の高い流動物（収容物と称する）が収容されるようになっており、断面が円形となる円筒形状に構成された円筒収容部２と、この円筒収容部２の下方の円形開口に沿って溶着される袋状収容部３とを備えている。   The container 1 according to the present embodiment is configured to receive a highly viscous fluid such as ink (referred to as a container), and a cylindrical container 2 configured in a cylindrical shape having a circular cross section; And a bag-like accommodation portion 3 welded along a circular opening below the cylindrical accommodation portion 2.

前記円筒収容部２には、一端側の中心軸上に、収容物を吸引可能な注出口２ａが形成されており、この注出口２ａには、キャップ等の封止部材（図示せず）が取着されて、収容物をシールしている。そして、実際の使用時には、封止部材を外した状態で外部装置の所定箇所に装填し、ポンプ等の吸引機構によって収容物が注出されるようになっている。この場合、封止部材に注出針を差し込んで、収容物を吸引するような構成であっても良い。   The cylindrical container 2 is formed with a spout 2a on the central axis on one end side capable of sucking the contents, and a sealing member (not shown) such as a cap is formed in the spout 2a. Attached to seal the contents. And in actual use, it loads in the predetermined location of an external device in the state which removed the sealing member, and the accommodation thing is poured out by suction mechanisms, such as a pump. In this case, a configuration may be adopted in which a dispensing needle is inserted into the sealing member to suck the contents.

前記円筒収容部２は、例えば、ポリエチレン、ポリスチレン、ポリプロピレン、ポリ塩化ビニール等のプラスチック材料によって一体成型（樹脂成型）されており、その肉厚については、吸引時において、袋状収容部３が内部に反転して引き込まれても、その円筒形状が維持される程度（例えば、０．３ｍｍ〜１．８ｍｍ程度）あれば良い。   The cylindrical housing portion 2 is integrally molded (resin molding) with a plastic material such as polyethylene, polystyrene, polypropylene, or polyvinyl chloride. Even if it is reversed and pulled in, it is sufficient that the cylindrical shape is maintained (for example, about 0.3 mm to 1.8 mm).

また、外形状（径の大きさ、長手方向の大きさ等）については、特に限定されることはないが、本実施形態では、図１及び図２（ａ）に示すように、円周状の側壁の上端側から中心軸上に位置する注出口２ａに向けて、次第に漏斗状に縮径する湾曲部２ｂが形成されている。そして、この湾曲部２ｂの内面には、注出口２ａに向けて延出するように、放射状突部２ｃを形成しておくことが好ましい。この放射状突部２ｃは、吸引時において、収容物が効果的に注出口２ａに向けて移動できるように流路ガイドを構成するものであり、成型時において一体形成することが可能である。この場合、放射状突部２ｃの具体的な延出長さ、間隔、高さについては、円筒収容部２の大きさ、収容物の種類（粘性）等に応じて適宜変形することが可能である。   Further, the outer shape (the size of the diameter, the size in the longitudinal direction, etc.) is not particularly limited, but in the present embodiment, as shown in FIG. 1 and FIG. A curved portion 2b that gradually decreases in the shape of a funnel is formed from the upper end of the side wall toward the spout 2a located on the central axis. And it is preferable to form the radial protrusion 2c in the inner surface of this curved part 2b so that it may extend toward the spout 2a. The radial protrusions 2c constitute a flow path guide so that the contained material can effectively move toward the spout 2a at the time of suction, and can be integrally formed at the time of molding. In this case, the specific extension length, interval, and height of the radial protrusions 2c can be appropriately changed according to the size of the cylindrical housing portion 2, the type (viscosity) of the housing, and the like. .

なお、上記した円筒収容部に形成される湾曲部２ｂについては、図２（ｂ）に示すように、円周状の側壁から緩やかな面２ｂ´で注出口２ａに移行するようにしても良いし、湾曲部を形成することなく、図２（ｃ）に示すように、側壁から平坦面２ｂ´´（略直角の面）で注出口２ａに移行するように構成しても良い。すなわち、吸引作用を受けた際、収容物が、均等に注出口に向けて移動できる構成となっていれば、その形状については適宜変形することが可能であり、更に、図２（ａ）の湾曲面よりも急テーパの湾曲面によって構成されていても良い。   In addition, about the curved part 2b formed in the above-mentioned cylindrical accommodating part, as shown in FIG.2 (b), you may make it transfer to the spout 2a by the gentle surface 2b 'from the circumferential side wall. However, as shown in FIG. 2C, the curved portion may be formed so as to shift from the side wall to the spout 2a on a flat surface 2b ″ (substantially perpendicular surface). In other words, when receiving the suction action, the shape can be appropriately modified as long as it is configured to be able to move evenly toward the spout, and further, as shown in FIG. You may be comprised by the curved surface of a taper rather than a curved surface.

前記円筒収容部２の下端側には、図２（ａ）に示すように、袋状収容部３の開口端部が溶着し易いように、溶着部２ｄが形成されている。この溶着部２ｄは、例えば、図に示すように、長手方向に所定の長さＬ２（５ｍｍ〜１５ｍｍ程度）を有し、円筒収容部２の円筒部に対して小径の円周面によって構成されている。これにより、袋状収容部３の開口領域をこの部分に被せておき、その後、リング状のヒートバー等を用いて熱溶着することで、円筒収容部２に対して袋状収容部３を容易に溶着することが可能となる。   As shown in FIG. 2A, a welding portion 2d is formed on the lower end side of the cylindrical housing portion 2 so that the opening end portion of the bag-shaped housing portion 3 is easily welded. For example, as shown in the drawing, the welding portion 2d has a predetermined length L2 (about 5 mm to 15 mm) in the longitudinal direction, and is configured by a circumferential surface having a small diameter with respect to the cylindrical portion of the cylindrical housing portion 2. ing. Thereby, the opening area | region of the bag-shaped accommodating part 3 is covered on this part, and the bag-shaped accommodating part 3 is easily attached with respect to the cylindrical accommodating part 2 by heat-welding using a ring-shaped heat bar etc. after that. It becomes possible to weld.

前記袋状収容部３は、ポリエチレン、ポリプロピレン、ポリ塩化ビニール等、柔軟性を有する薄膜状のフィルム（厚さが０．０５ｍｍ〜０．１５ｍｍ程度の薄膜フィルム）の周囲を溶着した袋状に構成されたものであり、例えば、２枚のフィルムを重ねて周囲を溶着した三方シール袋、或いは１枚のフィルムを折り曲げておき、サイドとボトムを溶着したニ方シール袋として構成されている。或いは、チューブ状の袋として構成されていても良い。   The bag-like storage part 3 is configured in a bag shape in which the periphery of a flexible thin film (thickness film having a thickness of about 0.05 mm to 0.15 mm) such as polyethylene, polypropylene, and polyvinyl chloride is welded. For example, it is configured as a three-sided seal bag in which two films are stacked and welded together, or a two-sided seal bag in which one film is bent and the side and bottom are welded. Or you may be comprised as a tube-shaped bag.

ここで、図３及び図４を参照して、袋状収容部の構成について説明する。
本発明における袋状収容部は、円筒収容部２の円形開口（溶着部２ｄ）に対して溶着できるように一端が開口すると共に、他端は平面となる底部が形成されていない構造（このような構造を非自立体と称する）となっている（溶着領域を斜線で示す）。また、本発明の袋状収容部は、溶着部２ｄとは反対の端部側の隅部が切り欠かれた構成となっている。具体的には、側面の形状が図３に示すような矩形状ではなく、例えば、図４（ａ）に示すように、端部側の隅部を切り欠くことで、図３に示す収容内部の底縁３ａと横縁３ｂとの間に９０度以下となるような角部Ｐが生じない構成となっている。 Here, with reference to FIG.3 and FIG.4, the structure of a bag-shaped accommodating part is demonstrated.
The bag-like accommodation portion in the present invention has a structure in which one end is opened so that it can be welded to the circular opening (welding portion 2d) of the cylindrical accommodation portion 2, and the other end is not formed with a flat bottom (such as this This structure is referred to as a non-self-solid structure) (the welding region is indicated by hatching). Moreover, the bag-shaped accommodating part of this invention becomes a structure by which the corner part by the side of the edge part opposite to the welding part 2d was notched. Specifically, the shape of the side surface is not rectangular as shown in FIG. 3, and for example, as shown in FIG. The corner P is not formed between the bottom edge 3a and the horizontal edge 3b of 90 degrees or less.

なお、図４（ｂ）及び（ｃ）に示すように、収容内部の底縁３ａと横縁３ｂとの間の切り欠きの態様については特に限定されることはなく、図４（ｂ）に示すように、底縁３ａが図４（ａ）に示すものと比較して短くなるように切り欠いても良いし、図４（ｃ）に示すように、底縁３ａが長くなるように切り欠いても良い。   As shown in FIGS. 4 (b) and 4 (c), there is no particular limitation on the form of the notch between the bottom edge 3a and the lateral edge 3b inside the housing, and FIG. As shown in FIG. 4, the bottom edge 3a may be cut away so as to be shorter than that shown in FIG. 4A, or the bottom edge 3a may be cut out as shown in FIG. 4C. May be missing.

この場合、切り欠き部分の形状、すなわち、切欠部となる縁形状３ｄについては、上記した円筒収容部２に形成される湾曲部２ｂに沿った形状に形成することが好ましい。具体的には、図４（ａ）に示す形状は、図２（ａ）に示す湾曲部が比較的緩やかな面となっている円筒収容部に対応させることが好ましく、図４（ｂ）に示す形状は、図２（ａ）に示す構成よりもさらに湾曲部２ｂが比較的長手方向に沿って長い面となっている円筒収容部に対応させることが好ましい。また、図４（ｃ）に示す形状は、図２（ｂ）に示すように湾曲部がより緩やかな面となっている円筒収容部に対応させることが好ましい。   In this case, the shape of the notch, that is, the edge shape 3d serving as the notch, is preferably formed in a shape along the curved portion 2b formed in the cylindrical housing portion 2 described above. Specifically, the shape shown in FIG. 4A is preferably made to correspond to the cylindrical housing portion in which the curved portion shown in FIG. 2A is a relatively gentle surface, as shown in FIG. It is preferable that the shape shown corresponds to a cylindrical housing portion in which the curved portion 2b has a relatively long surface along the longitudinal direction as compared with the configuration shown in FIG. Moreover, it is preferable to make the shape shown in FIG.4 (c) respond | correspond to the cylindrical accommodating part in which the curved part becomes a more gentle surface as shown in FIG.2 (b).

また、前記袋状収容部３の長さＬ１（図１（ｂ）参照）については、円筒収容部２の長手方向の収容長さＬに対して９０％から１１０％の範囲の長さとなるように構成される。これにより、袋状収容部３は、注出口２ａ部分から吸引を受けた際、収容物の流出に伴って円筒収容部２の内部空間に反転して引き込まれつつ、袋状収容部３の内面が、円筒収容部２の内面に密着するようになるが、上記した範囲の長さに設定しておくことで、収容内部の底縁３ａを、注出口２ａの収容部側の開口２Ａ近くに位置させることができ、効果的、かつ無駄なく収容物を注出することが可能となる。   Further, the length L1 (see FIG. 1 (b)) of the bag-shaped storage portion 3 is in the range of 90% to 110% with respect to the storage length L in the longitudinal direction of the cylindrical storage portion 2. Configured. Thereby, when the bag-shaped storage portion 3 receives suction from the spout 2a portion, the bag-shaped storage portion 3 is reversed and drawn into the internal space of the cylindrical storage portion 2 with the outflow of the stored items, and the inner surface of the bag-shaped storage portion 3 However, by setting the length within the above-mentioned range, the bottom edge 3a inside the housing is placed near the opening 2A on the housing portion side of the spout 2a. Therefore, it is possible to pour out the contents effectively and without waste.

すなわち、袋状収容部３の長さＬ１が、円筒収容部２の長手方向の収容長さＬに対して１１０％を超えてしまうと、収容物の流出に伴って袋状収容部３が反転しながら円筒収容部２の内部空間に反転して引き込まれた際、収容内部の底縁３ａが折れ曲がる等、注出口２ａの収容部側の開口２Ａを塞ぐ傾向が強くなり、これにより、吸引力が作用しなくなって注出口２ａの収容部側の開口２Ａ付近に存在する収容物を吸引しきれずに残留させてしまう可能性が高くなる。一方、袋状収容部３の長さＬ１が、円筒収容部２の長手方向の収容長さＬに対して９０％未満になってしまうと、収容部の流出に伴って袋状収容部３が反転しながら円筒収容部２の内部空間に反転して引き込まれた際、収容内部の底縁３ａと注出口２ａの収容部側の開口２Ａとの距離が離間してしまい、これにより、吸引によって内圧が下がって行くと、底縁３ａの領域に存在する収容物に対して十分な吸引がかからなくなり、そのまま残留させてしまう可能性が高くなる。   That is, if the length L1 of the bag-shaped storage portion 3 exceeds 110% with respect to the length L of the cylindrical storage portion 2 in the longitudinal direction, the bag-shaped storage portion 3 is reversed as the stored item flows out. However, when retracted into the internal space of the cylindrical housing portion 2, the bottom edge 3 a inside the housing is bent, and the tendency to block the opening 2 </ b> A on the housing portion side of the spout 2 a becomes strong. No longer acts, and there is a high possibility that the contents present in the vicinity of the opening 2A on the container portion side of the spout 2a will remain without being completely sucked. On the other hand, when the length L1 of the bag-shaped storage portion 3 becomes less than 90% with respect to the length L of the cylindrical storage portion 2 in the longitudinal direction, the bag-shaped storage portion 3 is moved with the outflow of the storage portion. When reversed and retracted into the internal space of the cylindrical housing portion 2 while being reversed, the distance between the bottom edge 3a inside the housing and the opening 2A on the housing portion side of the spout 2a is separated. When the internal pressure decreases, there is a high possibility that sufficient suction will not be applied to the contents present in the region of the bottom edge 3a, and it will remain as it is.

次に、図２（ａ）に示す構成の円筒収容部２に図４（ａ）に示す袋状収容部３を溶着して収容体を構成し、ここに粘性の高い収容物（市販されているマヨネーズ）を収容して一定の吸引力をかけ、その収容物を注出をした結果について図５（ａ）〜（ｆ）を参照しながら説明する。   Next, a bag-shaped container 3 shown in FIG. 4 (a) is welded to the cylindrical container 2 having the structure shown in FIG. 2 (a) to form a container, and a highly viscous container (commercially available) The result of storing the mayonnaise), applying a certain suction force, and dispensing the stored material will be described with reference to FIGS.

まず、円筒収容部２及び袋状収容部３に収容物を収容した状態（図５（ａ）参照）で、注出口２に対して吸引をかけて収容物を注出して行くと、袋状収容部３は縦皺が発生しながら次第に萎んで行き、底縁３ａが円筒収容部２の円形開口（溶着部２ｄの領域）に向けて上昇する（図５（ｂ）及び（ｃ）参照）。さらに吸引して行くと、収容物の流出に伴って収容内部の底縁３ａが円筒収容部２の円形開口（溶着部２ｄの領域）を通過して上昇し、袋状収容部３は、円筒収容部２の内部空間に反転して引き込まれる（図５（ｄ）及び（ｅ）参照）。そして、さらに吸引すると、袋状収容部３の内面が、円筒収容部２の内面に密着し（図５（ｆ）参照）、収容物は注出口２の収容部側開口領域に集中するようになる。   First, in the state in which the container is stored in the cylindrical container 2 and the bag-shaped container 3 (see FIG. 5A), the container 2 is sucked into the bag outlet 2 by sucking the container 2. The container 3 gradually shrinks while generating vertical fistulas, and the bottom edge 3a rises toward the circular opening (region of the welded part 2d) of the cylindrical container 2 (see FIGS. 5B and 5C). . When the suction is further performed, the bottom edge 3a inside the housing passes through the circular opening (region of the welded portion 2d) of the cylindrical housing portion 2 as the stored material flows out, and the bag-shaped housing portion 3 has a cylindrical shape. It is reversed and drawn into the internal space of the housing part 2 (see FIGS. 5D and 5E). When sucked further, the inner surface of the bag-shaped storage portion 3 is brought into close contact with the inner surface of the cylindrical storage portion 2 (see FIG. 5 (f)), and the stored items are concentrated in the storage portion side opening region of the spout 2. Become.

なお、図５（ｆ）に示すように、袋状収容部３が円筒収容部２の内部空間に反転して引き込まれると、袋状収容部３の内面は、円筒収容部２の内面に密着するようになるが、円筒収容部２の内面は湾曲面であって角部が存在していないことから、袋状収容部３は、皺が生じた状態で密着し難くなり、可能な限り収容物を吸い出す（押し出す）ことが可能となる。また、袋状収容部３の内面が円筒収容部２の内面に密着すると、吸引力が袋状収容部３に対して作用しなくなるが、注出口２ａ側に向けて漏斗状に次第に縮径するような湾曲形状となっているため、吸引力が低下しても可能な限り収容物を注出することが可能となる。   As shown in FIG. 5 (f), when the bag-shaped container 3 is reversed and drawn into the internal space of the cylindrical container 2, the inner surface of the bag-shaped container 3 is in close contact with the inner surface of the cylindrical container 2. However, since the inner surface of the cylindrical housing portion 2 is a curved surface and there are no corners, the bag-like housing portion 3 is difficult to adhere in a state where wrinkles are generated, and is accommodated as much as possible. It is possible to suck out (push out) things. In addition, when the inner surface of the bag-shaped storage unit 3 is in close contact with the inner surface of the cylindrical storage unit 2, suction force does not act on the bag-shaped storage unit 3, but the diameter gradually decreases in a funnel shape toward the spout 2a. Since it becomes such a curved shape, even if suction force falls, it becomes possible to pour out what is possible.

この場合、上記したように、湾曲部２ｂの内面に、注出口２ａに向けて延出する放射状突部２ｃを形成しているため、注出口２ａに向かう流路が確保され易くなって、効率的に収容物を注出することが可能となる。   In this case, as described above, since the radial protrusions 2c extending toward the spout 2a are formed on the inner surface of the curved portion 2b, a flow path toward the spout 2a is easily secured, and efficiency is improved. It is possible to pour out the contents.

さらに、袋状収容部３は、薄膜フィルムによって構成されているため、部分的に伸縮することもあるが、その長さＬ１を、円筒収容部２の長手方向の収容長さＬに対して９０％から１１０％にしておくことにより、図５（ｆ）に示すように、底縁３ａ領域を注出口部分の近辺に位置させることができ、これにより、吸引によって内圧が下がっても効率的に収容物を注出することが可能となる。特に、袋状収容部３は、非自立体にして端部側の隅部を切り欠くことで底縁部に鋭角となる角部が存在しないように構成されており、しかも、切欠部の縁形状を、円筒収容部２の湾曲部に沿うように形成したことから、収容物を残留させることなく、効率的に注出することが可能となる。   Furthermore, since the bag-shaped storage unit 3 is formed of a thin film, the bag-shaped storage unit 3 may partially expand and contract, but its length L1 is 90 with respect to the storage length L in the longitudinal direction of the cylindrical storage unit 2. By setting the percentage from 110% to 110%, the bottom edge 3a region can be positioned in the vicinity of the spout portion as shown in FIG. 5 (f). It is possible to pour out the contents. In particular, the bag-like storage portion 3 is configured to be non-self-solid and not to have an acute corner at the bottom edge by notching the end-side corner, and the edge of the notch Since the shape is formed so as to be along the curved portion of the cylindrical housing portion 2, it is possible to efficiently pour out without leaving the contents.

なお、実際に、図４（ａ）に示した構造の袋状収容部と、図３に示した端部側の隅部を切り欠かない構成について、同一の条件下で吸引試験を実施したところ、図３に示した構造の袋状収容部３では、当初の充填重量に対して５．７０％の収容物が残留したのに対し、図４（ａ）に示した構造（隅部を切り欠いた構造）では、３．０７％の収容物が残留しただけに留まり、効率的に収容物が注出できる結果が得られた。   Actually, when the suction test was performed under the same conditions for the bag-shaped housing portion having the structure shown in FIG. 4A and the configuration in which the corner portion on the end side shown in FIG. 3 was not cut out. In the bag-shaped container 3 having the structure shown in FIG. 3, 5.70% of the stored material remained with respect to the initial filling weight, whereas the structure shown in FIG. With the lack of structure), only 3.07% of the contained material remained, and the result was that the contained material could be efficiently poured out.

そして、上記したような収容体１は、注出口２ａを有する樹脂成型された円筒収容部２に対し、非自立体となる袋状に形成された袋状収容部３を、円筒収容部２の他端側の円形開口に沿って溶着した構造であるため、構造がシンプルであり、かつ容易に製造できるため、コストの低減、及びリサイクル等がし易い構成が得られるようになる。   The container 1 as described above has a bag-shaped container 3 formed in a non-self-contained bag shape with respect to the resin-molded cylindrical container 2 having the spout 2a. Since the structure is welded along the circular opening on the other end side, the structure is simple and can be easily manufactured, so that a configuration that is easy to reduce costs, recycle, and the like can be obtained.

図６は、上記した収容体１の注出口部分に装着される閉塞防止部材を示しており、図６（ａ）は斜視図、（ｂ）は正面図、（ｃ）は平面図である。収容体１には、例えば、図６に示す閉塞防止部材２０を、図７に示すように注出口部分に装着することで、より効率的に収容物を注出することが可能となる。   FIGS. 6A and 6B show a blocking prevention member mounted on the spout portion of the container 1 described above, FIG. 6A is a perspective view, FIG. 6B is a front view, and FIG. 6C is a plan view. For example, by attaching the blocking prevention member 20 shown in FIG. 6 to the spout portion of the container 1 as shown in FIG. 7, it becomes possible to pour out the contained material more efficiently.

前記閉塞防止部材２０は、樹脂等によって一体成型されており、注出口２ａに挿入される筒部２１と、注出口に挿入された際、内部に落ち込まないように、注出口２ａの円周縁２ａ´と当接するフランジ２２とを備えており、注出口２に対して着脱可能に構成されている。   The blocking prevention member 20 is integrally formed of resin or the like, and the cylindrical portion 21 inserted into the spout 2a and the circumferential edge 2a of the spout 2a so as not to fall into the interior when inserted into the spout. ′ And a flange 22 that abuts, and is configured to be detachable from the spout 2.

前記筒部２１は、注出口２ａの軸方向長さと略同一の軸長さを備えており、その先端が注出口２ａの収容部側の開口２Ａに位置するように構成されている。そして、筒部２１の端面には、所定間隔おいて複数（本実施形態では、略９０°間隔で４箇所）の切欠溝２１ａが形成されている。   The cylindrical portion 21 has an axial length that is substantially the same as the axial length of the spout 2a, and is configured such that its tip is located in the opening 2A on the accommodating portion side of the spout 2a. A plurality of cutout grooves 21a (in the present embodiment, four locations at approximately 90 ° intervals) are formed on the end surface of the cylindrical portion 21 at predetermined intervals.

このような切欠溝２１ａは、吸引時において、最終的に袋状収容部３の内面が円筒収容部２の内面に密着し、吸引力が袋状収容部３に作用しなくなった段階で、図７に示すように、袋状収容部３の底縁３ａ付近（開口２Ａ付近）に残留する収容物を、切欠溝２１ａを介して注出し易くする機能を備えている。すなわち、袋状収容部３の内面が円筒収容部２の内面に密着するまでは、収容物は、筒部２１を通過して注出されるが、最終的に収容物の残量が減ると、その付近に存在する残留物は、移動経路が細い切欠溝２１ａを介して注出し易くなり、可能な限り、収容物の残留量を削減することが可能となる。   Such a notch 21a is formed at the stage where the inner surface of the bag-like storage portion 3 is finally brought into close contact with the inner surface of the cylindrical storage portion 2 during suction, and the suction force no longer acts on the bag-like storage portion 3. As shown in FIG. 7, the baggage-containing portion 3 has a function of facilitating pouring out the remaining items near the bottom edge 3a (near the opening 2A) through the cutout groove 21a. That is, until the inner surface of the bag-shaped storage unit 3 is in close contact with the inner surface of the cylindrical storage unit 2, the stored item is poured out through the tube part 21, but when the remaining amount of the stored item is finally reduced, Residues present in the vicinity thereof can be easily poured out through the notch groove 21a having a narrow movement path, and the residual amount of the contained material can be reduced as much as possible.

上記したような閉塞防止部材２０を設置したことで、さらに最終的な収容物の残量率を約２％向上することが可能となる。   By installing the blocking prevention member 20 as described above, it is possible to further improve the final percentage of the remaining contents by about 2%.

なお、上記したような閉塞防止部材２０については、図に示したように、注出口２に対して着脱可能に構成しても良いし、注出口部分に予め一体形成しておいても良い。また、筒部２１の長さ、肉厚、切欠溝２１ａの形成個数等、適宜変形することが可能である。   As shown in the drawing, the blocking prevention member 20 as described above may be configured to be detachable from the spout 2 or may be integrally formed in advance at the spout. Further, the length and thickness of the cylindrical portion 21 and the number of formed notches 21a can be appropriately modified.

以上、本発明の実施の形態について説明したが、本発明は、上記した実施形態に限定されることはなく、種々変形することが可能である。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.

例えば、袋状収容部３の端部に形成される切り欠きは、その収容空間に９０°以下の鋭角部分が存在しないように切り欠かれていれば良く、非自立体の端部を円弧状に切り欠いたものであっても良い。或いは、円弧状にすること無く、複数の直線で多段に亘って切り欠いても良い。また、円筒収容部２の大きさ、側面から注出口２に至る形状、円筒収容部２と袋状収容部３の溶着方法、円筒収容部２における注出口２ａの構成等、適宜変形することが可能である。   For example, the cutout formed at the end of the bag-shaped storage portion 3 may be cut out so that there is no acute angle portion of 90 ° or less in the storage space. It may be a notch. Alternatively, a plurality of straight lines may be cut out in multiple stages without forming an arc shape. Also, the size of the cylindrical housing portion 2, the shape from the side surface to the spout 2, the welding method of the cylindrical housing 2 and the bag-shaped housing 3, the configuration of the spout 2 a in the cylindrical housing 2, etc. can be modified as appropriate.
