図１～図４に示すように本実施形態の液体注出具は、ポンプ７を用いて液体を注出する液体注出具１０であり、液体を貯留する貯留具２と、ポンプ７を通す貫通孔である挿通孔１ａと、貯留具２を支持するための貫通孔である支持孔１ｂと、を備えた支持具１と、を有し、貯留具２は、支持孔１ｂより狭い底面２ｅを有する幅狭部２ａと、支持孔１ｂより広い開口を有する幅広部２ｂと、を備えている。支持具１、貯留具２としては合成樹脂を用いることができるが、本実施形態では、いずれもポリプロピレン製である。貯留具２は透明であることが好ましい。貯留具２が透明であることにより、貯留具に貯留された液体が側面から視認可能となるためである。 As shown in FIGS. 1 to 4, the liquid dispensing device of this embodiment is a liquid dispensing device 10 that dispenses liquid using a pump 7, and includes a storage device 2 that stores liquid and a through hole through which the pump 7 passes. The storage device 2 has a bottom surface 2e narrower than the support hole 1b. It includes a narrow portion 2a and a wide portion 2b having an opening wider than the support hole 1b. Although synthetic resin can be used for the support 1 and the storage device 2, in this embodiment, both are made of polypropylene. Preferably, the reservoir 2 is transparent. This is because the storage device 2 is transparent, so that the liquid stored in the storage device can be visually recognized from the side.
押圧部３、注出部４、導通管５、係止部６、ポンプ７、パイプ８は、液体注出具１０を構成する部材である。液体注出具１０は、従来公知のポンプ式ディスペンサーと同様の機構を備え、押圧部３を下方に押圧することにより、パイプ８、ポンプ７を介して導通管５に液体が吸い上げられ、注出部４から液体が注出される。押圧部３、注出部４、導通管５は、例えば、ポリプロピレン等の合成樹脂で一体成形されている。注出部４、導通管５の内部は連通しており、導通管５の下端側から、注出部４に形成された開口である注出口まで、液体が流れることができるようになっている。導通管５は、下端側がポンプ７内で上下に移動が可能となっている。本明細書において、液体とは、粘性の程度に関わらず、気体、固体以外の状態の物質を意味する。 The pressing part 3, the pouring part 4, the conduit 5, the locking part 6, the pump 7, and the pipe 8 are members that constitute the liquid pouring tool 10. The liquid spouting tool 10 has a mechanism similar to a conventionally known pump-type dispenser, and by pressing the pressing part 3 downward, liquid is drawn up into the conduit pipe 5 via the pipe 8 and the pump 7, and the liquid is drawn up into the spouting part. Liquid is poured out from 4. The pressing part 3, the pouring part 4, and the conduit tube 5 are integrally molded from synthetic resin such as polypropylene, for example. The insides of the spouting section 4 and the conduit tube 5 are in communication, so that liquid can flow from the lower end side of the conduit tube 5 to the spout, which is an opening formed in the spouting section 4. . The lower end of the conduit tube 5 is movable up and down within the pump 7. In this specification, liquid means a substance in a state other than gas or solid, regardless of the degree of viscosity.
本実施形態で用いる紙容器ＫＦは、市販されている飲料容器等（図５参照）に使用されるタイプのものであり、フラットトップ型のトップである上面にプラスチック製の注出口ＫＦｃが形成されている。図８は、紙容器ＫＦからキャップを取り外した状態を示す部分断面図である。図８においては、注出口ＫＦｃは側面、紙容器ＫＦ内は断面で示している。紙容器ＫＦの注出口ＫＦｃは筒状であり、筒状の注出口の外面側にネジ山、ネジ溝等の螺子構造が形成されており、内面側にネジ溝、ネジ山等の対応する螺子構造が形成されたキャップＣＰと螺合可能になっている。製造時には、注出口ＫＦｃとキャップＣＰは各々成型した後、セット加工され、紙容器ＫＦに装着される。 The paper container KF used in this embodiment is of the type used for commercially available beverage containers, etc. (see Figure 5), and has a plastic spout KFc formed on the top surface, which is a flat top type top. ing. FIG. 8 is a partial sectional view showing a state in which the cap is removed from the paper container KF. In FIG. 8, the spout KFc is shown on the side, and the inside of the paper container KF is shown in cross section. The spout KFc of the paper container KF is cylindrical, and has a threaded structure such as threads and thread grooves formed on the outer surface of the cylindrical spout, and a corresponding screw structure such as threads and threads on the inner surface. It can be screwed into a cap CP with a structure formed thereon. During manufacturing, the spout KFc and the cap CP are each molded, then processed as a set, and attached to the paper container KF.
そのような状態において、内容物である液体の充填後、図５に示すような形態で販売が行われる。そして、購入後、消費者は、キャップＣＰを注出口ＫＦｃから分離することにより開封する。これにより、注出口ＫＦｃから紙容器ＫＦの内容物である液体を注出することが可能な状態となる。このような紙容器ＫＦの内容物としては、飲料類、調味料類、油脂類、液体洗剤類等の様々な液体が収容される。 In such a state, after filling with liquid as the contents, sales are carried out in the form shown in FIG. 5. After purchasing, the consumer opens the cap CP by separating it from the spout KFc. This makes it possible to pour out the liquid that is the contents of the paper container KF from the spout KFc. The contents of such a paper container KF include various liquids such as beverages, seasonings, oils and fats, and liquid detergents.
係止部６は、液体注出具を紙容器ＫＦと結合させるための部材である。係止部６は、キャップＣＰと略同一の大きさであり、構造もキャップＣＰと同様であるが、天面側（図２における上側）に開口が形成されており、全体として筒状になっている。係止部６は、その筒状の内面側にキャップＣＰと同一仕様の螺子構造が形成されており、キャップＣＰと同様に、紙容器ＫＦの注出口ＫＦｃと螺合可能になっている。 The locking portion 6 is a member for connecting the liquid pouring tool to the paper container KF. The locking part 6 is approximately the same size as the cap CP, and has the same structure as the cap CP, but an opening is formed on the top surface side (the upper side in FIG. 2), and the locking part 6 has a cylindrical shape as a whole. ing. The locking part 6 has a threaded structure having the same specifications as the cap CP formed on its cylindrical inner surface, and can be screwed into the spout KFc of the paper container KF like the cap CP.
図２の側面図に示すように、紙容器ＫＦ内には、導通管５から空洞が連続するポンプ７、パイプ８が形成されている。なお、図２においては、紙容器ＫＦの内部に挿入されたポンプ７、パイプ８を破線で示している。筒状の導通管５は、係止部６の内径よりも小さく、係止部６を貫通している。ポンプ７の内部には、バネ（図示省略）が挿入されている。このため、押圧部３を下方に押すと、バネが下方向に縮み、押圧部３への力を解除すると、バネが上方向（図２の上方向、押圧部３側）に戻る構造となっている。ポンプ７内には、弁が設置されており、押圧部３を下方に押した状態から戻した際に、パイプ８から液体を引き込む構造となっている。このようなバネや弁を備えたポンプによる液体の注入および注出工程は公知のものを用いることができるので、詳細な説明は省略する。 As shown in the side view of FIG. 2, inside the paper container KF, a pump 7 and a pipe 8 are formed, each having a cavity connected to the conduit tube 5. In addition, in FIG. 2, the pump 7 and pipe 8 inserted into the paper container KF are shown by broken lines. The cylindrical conduction pipe 5 has a smaller inner diameter than the locking part 6 and passes through the locking part 6. A spring (not shown) is inserted inside the pump 7. Therefore, when the pressing part 3 is pushed downward, the spring contracts downward, and when the force on the pressing part 3 is released, the spring returns upward (upward in FIG. 2, toward the pressing part 3). ing. A valve is installed inside the pump 7, and has a structure that draws liquid from the pipe 8 when the pressing part 3 is returned from the downwardly pressed state. Known processes for injecting and dispensing liquid using a pump equipped with such springs and valves can be used, so detailed explanations will be omitted.
係止部６付近の状態は、上述のような構成であるため、キャップＣＰを紙容器ＫＦから外した後、液体注出具１０のポンプ７及びパイプ８の部分を、支持具１の挿通孔１ａを通して、紙容器ＫＦの注出口ＫＦｃの内側に挿入し、係止部６を注出口ＫＦｃの外面と螺合させることにより、注出口ＫＦｃと固定され、液体注出具１０は紙容器ＫＦに装着される。このようにして装着された状態が、図１、図２に示した状態である。 Since the state near the locking part 6 is as described above, after removing the cap CP from the paper container KF, the pump 7 and pipe 8 portion of the liquid spouting tool 10 are inserted into the insertion hole 1a of the support tool 1. The liquid spout 10 is inserted into the inside of the spout KFc of the paper container KF, and is fixed to the spout KFc by screwing the locking part 6 with the outer surface of the spout KFc, and the liquid spout 10 is attached to the paper container KF. Ru. The state where the device is mounted in this manner is the state shown in FIGS. 1 and 2.
支持具１は、貯留具２を所定の位置で支持するための支持具である。図４に示したように、支持具１は、支持具１を紙容器ＫＦに固定するための貫通孔である挿通孔１ａと、貯留具２を支持するための貫通孔である支持孔１ｂを有している。本実施形態では、挿通孔１ａは円形であり、紙容器ＫＦの注出口ＫＦｃも円形であり、係止部６も円形である。挿通孔１ａの直径Ｌ６は、注出口ＫＦｃの外径より大きく、係止部６の外径より小さい。 The support 1 is a support for supporting the storage device 2 at a predetermined position. As shown in FIG. 4, the support 1 has an insertion hole 1a that is a through hole for fixing the support 1 to the paper container KF, and a support hole 1b that is a through hole for supporting the storage device 2. have. In this embodiment, the insertion hole 1a is circular, the spout KFc of the paper container KF is also circular, and the locking part 6 is also circular. The diameter L6 of the insertion hole 1a is larger than the outer diameter of the spout KFc and smaller than the outer diameter of the locking part 6.
本実施形態では、支持孔１ｂは円形であり、支持孔１ｂの直径Ｌ７は、挿通孔１ａより大きい。ここで、挿通孔１ａの縁と支持孔１ｂの縁を結ぶ線分の最短の長さをＬ８とする。長さＬ８は、挿通孔１ａの縁と支持孔１ｂの縁の最短の距離と言い換えることもできる。図４に示すように、本実施形態においては、長さＬ８は、支持具１の長手方向における、挿通孔１ａの中心と支持孔１ｂの中心を結ぶ線分上に存在する縁どうしの距離となる。支持具１の形状を規定する各長さＬ６、Ｌ７、Ｌ８は、貯留具２、押圧部３、注出部４のサイズや形状との関係により定まる。これらの関係については、後述する。 In this embodiment, the support hole 1b is circular, and the diameter L7 of the support hole 1b is larger than the insertion hole 1a. Here, the shortest length of the line segment connecting the edge of the insertion hole 1a and the edge of the support hole 1b is defined as L8. The length L8 can also be expressed as the shortest distance between the edge of the insertion hole 1a and the edge of the support hole 1b. As shown in FIG. 4, in this embodiment, the length L8 is the distance between the edges existing on the line segment connecting the center of the insertion hole 1a and the center of the support hole 1b in the longitudinal direction of the support 1. Become. The lengths L6, L7, and L8 that define the shape of the support tool 1 are determined by the relationship with the sizes and shapes of the storage tool 2, the pressing section 3, and the pouring section 4. These relationships will be described later.
挿通孔１ａの直径Ｌ６については、上述のように、注出口ＫＦｃの外径より大きい。このため、注出口ＫＦｃが挿通孔１ａに収まるように支持具１を配置した後、注出口ＫＦｃに液体注出具１０のポンプ７及びパイプ８の部分を挿入することにより、支持具１は、紙容器ＫＦの上面ＫＦａに平行な面において回転可能な状態に維持される。さらに、係止部６の内面の螺子構造と、注出口ＫＦｃの外面の螺子構造を螺合させる。そして、挿通孔１ａの周囲において、支持具１を係止部６と紙容器ＫＦの上面ＫＦａで挟み、係止部６の下方への押圧力により、支持具１を固定する。図１、図２の例では、支持孔１ｂを紙容器ＫＦの上面ＫＦａから突出した位置となるようにして、支持具１を固定している。 The diameter L6 of the insertion hole 1a is larger than the outer diameter of the spout KFc, as described above. Therefore, after arranging the support 1 so that the spout KFc fits into the insertion hole 1a, by inserting the pump 7 and pipe 8 portions of the liquid spout 10 into the spout KFc, the support 1 can be It is maintained in a rotatable state in a plane parallel to the upper surface KFa of the container KF. Further, the threaded structure on the inner surface of the locking portion 6 and the threaded structure on the outer surface of the spout KFc are screwed together. Then, around the insertion hole 1a, the support 1 is sandwiched between the locking part 6 and the upper surface KFa of the paper container KF, and the support 1 is fixed by the downward pressing force of the locking part 6. In the example shown in FIGS. 1 and 2, the support 1 is fixed so that the support hole 1b is located at a position protruding from the upper surface KFa of the paper container KF.
図３は、本発明の一実施形態に係る貯留具を示す図である。図３（ａ）は、貯留具の側面図であり、図３（ｂ）は、貯留具の上面図であり、図３（ｃ）は、貯留具の下面図である。図３（ａ）において、上方には、液体を注入可能な開口を有する幅広部２ｂが形成されており、下方には、液体を貯留可能な底面を有する幅狭部２ａが形成されている。図３（ｂ）の上面図は、幅広部２ｂ側から見た図であり、図３（ｃ）は、幅狭部２ａ側から見た図である。貯留具２については、注出部４から注出された液体を貯留することを主要な役割としているので、図１、図２、図３（ａ）に示したように、幅狭部２ａを下、幅広部２ｂを上として平坦な幅狭部２ａの底面２ｅを水平面に載置した状態で、上下方向について説明するものとする。 FIG. 3 is a diagram showing a storage device according to an embodiment of the present invention. 3(a) is a side view of the storage device, FIG. 3(b) is a top view of the storage device, and FIG. 3(c) is a bottom view of the storage device. In FIG. 3A, a wide part 2b having an opening into which liquid can be injected is formed at the upper part, and a narrow part 2a having a bottom surface capable of storing liquid is formed at the lower part. The top view of FIG. 3(b) is a view seen from the wide part 2b side, and FIG. 3(c) is a view seen from the narrow part 2a side. The main role of the storage device 2 is to store the liquid poured out from the spouting part 4, so as shown in FIGS. 1, 2, and 3(a), the narrow part 2a is The vertical direction will be described with the bottom surface 2e of the flat narrow portion 2a placed on a horizontal surface with the wide portion 2b facing upward.
図２、図３（ａ）に簡易的に示してあるが、本実施形態に係る貯留具２の側面には、液体の量を示すための目盛が形成されている。この目盛を参照することにより、例えば、貯留された液体が何ｍｌ（ミリリットル）であるかを計量することができる。この場合、貯留具２は、いわゆる計量カップとして用いられる計量具としても機能する。単に貯留することを目的とする場合には、目盛を形成しておかなくてもよい。 As shown simply in FIGS. 2 and 3(a), a scale for indicating the amount of liquid is formed on the side surface of the storage device 2 according to this embodiment. By referring to this scale, it is possible to measure, for example, how many milliliters (ml) of the stored liquid is present. In this case, the storage tool 2 also functions as a measuring tool used as a so-called measuring cup. If the purpose is simply to store, it is not necessary to form a scale.
本実施形態では、幅広部２ｂ、幅狭部２ａは、ともに円形状である。幅広部２ｂの外径が支持孔１ｂより大きく、幅狭部２ａの外径が支持孔１ｂより小さいことにより、幅広部２ｂの周壁下端が、支持孔１ｂの周縁に掛かるようになり、支持具１で貯留具２を支持することが可能となる。 In this embodiment, both the wide portion 2b and the narrow portion 2a are circular. Since the outer diameter of the wide part 2b is larger than the support hole 1b and the outer diameter of the narrow part 2a is smaller than the support hole 1b, the lower end of the peripheral wall of the wide part 2b hangs on the peripheral edge of the support hole 1b, and the support tool 1 can support the storage device 2.
また、貯留具２は、幅広部２ｂに延設された突出部２ｃを備えている。突出部２ｃは、液体が貯留具２に貯留された状態でも、指で把持し易いように円形の幅広部２ｂから所定の方向に突出した部分である。本実施形態では、幅広部２ｂと突出部２ｃの上側は開放された開口面となっている。幅広部２ｂと突出部２ｃの開口面２ｄは同一面であり、幅狭部２ａの底面２ｅを水平面に載置したときに、水平面上に存在する。 Further, the storage device 2 includes a protruding portion 2c extending from the wide portion 2b. The protruding portion 2c is a portion that protrudes in a predetermined direction from the circular wide portion 2b so that it can be easily grasped with fingers even when liquid is stored in the reservoir 2. In this embodiment, the upper sides of the wide portion 2b and the protruding portion 2c are open surfaces. The wide portion 2b and the opening surface 2d of the protruding portion 2c are on the same plane, and exist on a horizontal surface when the bottom surface 2e of the narrow portion 2a is placed on the horizontal surface.

For this reason, the inside of the storage device 2 needs to be of a size in which the pressing part 3 and the pouring part 4 can fit. As shown in FIG. 3, in the height (depth) direction of the storage device 2, the height from the opening surface 2d to the inner surface of the bottom surface 2e is H1, and from the boundary surface between the narrow part 2a and the wide part 2b. The height to the opening surface is H2, and the height from the opening surface 2d to the inner surface of the protrusion bottom surface 2f is H3.
また、押圧部３による押圧の方向（導通管５の延伸方向）と交差する平方向（図３における左右方向）においては、互いに対向する幅広部２ｂと突出部２ｃの内縁間を結ぶ線分の長さ（対向する幅広部２ｂと突出部２ｃの内縁間の距離）をＬ１、幅広部２ｂと突出部２ｃの内縁間を結ぶ線分と直交する幅広部２ｂの内径（長さ）をＬ２、幅広部２ｂと突出部２ｃの内縁間を結ぶ線分と直交する、突出部２ｃの内縁間を結ぶ線分の長さ（対向する幅広部２ｂと突出部２ｃの内縁間の距離）をＬ３、底面２ｅの内面側における幅狭部２ａの内径（長さ）をＬ４とする。また、支持孔１ｂに貯留具２を載置した状態で、係止部６の方向に向かって突出する貯留具２の長さをＬ５とする。 In addition, in the horizontal direction (left-right direction in FIG. 3) intersecting the direction of pressing by the pressing part 3 (the extending direction of the conductive tube 5), a line segment connecting the inner edges of the wide part 2b and the protruding part 2c that face each other is The length (distance between the inner edges of the wide part 2b and the protruding part 2c that face each other) is L1, and the inner diameter (length) of the wide part 2b perpendicular to the line connecting the inner edges of the wide part 2b and the protruding part 2c is L2. The length of the line segment connecting the inner edges of the protrusion 2c that is perpendicular to the line segment connecting the inner edges of the wide portion 2b and the protrusion 2c (the distance between the opposing inner edges of the wide portion 2b and the protrusion 2c) is L3, The inner diameter (length) of the narrow portion 2a on the inner surface side of the bottom surface 2e is L4. Further, the length of the storage device 2 that protrudes toward the locking portion 6 in a state where the storage device 2 is placed in the support hole 1b is L5.
本実施形態に係る液体注出具では、押圧部３、注出部４を貯留具２の内部に収めて、コンパクトにまとめる（図６参照）ことを可能としている。この場合、貯留具２は、キャップとしての役割も果たす。上記のように、高さＨ１、Ｈ２、Ｈ３、長さＬ１、Ｌ２、Ｌ３、Ｌ４を定義した際、押圧部３、注出部４を貯留具２の内部に収めるためには、これらの高さ、長さが、押圧部３、注出部４、係止部６等との関係で所定の条件を満たす必要がある。 In the liquid pouring device according to this embodiment, the pressing portion 3 and the pouring portion 4 are housed inside the storage device 2, making it possible to make it compact (see FIG. 6). In this case, the reservoir 2 also serves as a cap. As mentioned above, when heights H1, H2, H3 and lengths L1, L2, L3, and L4 are defined, these heights must be adjusted in order to fit the pressing part 3 and spouting part 4 inside the storage device 2. It is necessary for the length and length to satisfy predetermined conditions in relation to the pressing part 3, pouring part 4, locking part 6, etc.
ここで、螺子構造５ａを係止部６の螺子構造と螺合させて、押圧部３を係止部６に最大限近づけた場合を想定する。図７は、螺子構造５ａを係止部６の螺子構造と螺合させて、押圧部３を係止部６に最大限近づけた状態を示す図である。この状態において、係止部６の下端から押圧部３の上端（天面）までの高さをＨＯとする。また、水平方向における形状が円形である押圧部３の直径をＬＯとする。そして、押圧部３から延びる注出部４の開口側の先端４ａから、注出部４と反対側の押圧部３の端までの長さをＬＣとする。さらに、注出部４の開口側の先端４ａから、円形の押圧部３の中心までの長さをＬＣ２とする。水平方向において、押圧部３の中心は、導通管５の中心軸と一致する。 Here, it is assumed that the screw structure 5a is screwed together with the screw structure of the locking part 6 to bring the pressing part 3 as close as possible to the locking part 6. FIG. 7 is a diagram showing a state in which the screw structure 5a is screwed together with the screw structure of the locking part 6, and the pressing part 3 is brought as close as possible to the locking part 6. In this state, the height from the lower end of the locking part 6 to the upper end (top surface) of the pressing part 3 is defined as HO. Further, the diameter of the pressing portion 3 having a circular shape in the horizontal direction is defined as LO. The length from the tip 4a on the opening side of the spouting part 4 extending from the pressing part 3 to the end of the pressing part 3 on the opposite side to the spouting part 4 is defined as LC. Further, the length from the opening side tip 4a of the spouting part 4 to the center of the circular pressing part 3 is defined as LC2. In the horizontal direction, the center of the pressing part 3 coincides with the central axis of the conduction tube 5.
押圧部３、注出部４を貯留具２の内部に収めるためには、液体注出具１０は、導通管５の延伸方向と直交する水平方向（水平面）における押圧部３と注出部４の外縁形状が、貯留具２の幅広部２ｂおよび突出部２ｃの内縁形状よりも小さく、かつ、導通管５の延伸方向である垂直方向における押圧部３の外縁形状が、貯留具２の幅広部２ｂおよび突出部２ｃの内縁形状よりも小さく、かつ、垂直方向における押圧部３と注出部４の外縁形状が、貯留具２の幅広部２ｂおよび突出部２ｃの内縁形状よりも小さいことが条件となる。 In order to accommodate the pressing part 3 and the spouting part 4 inside the storage device 2, the liquid spouting tool 10 has to fit the pressing part 3 and the spouting part 4 in the horizontal direction (horizontal plane) perpendicular to the extending direction of the conduit tube 5. The outer edge shape is smaller than the inner edge shape of the wide part 2b and the protruding part 2c of the storage device 2, and the outer edge shape of the pressing part 3 in the vertical direction, which is the extending direction of the conduction tube 5, is the wide part 2b of the storage device 2. and smaller than the inner edge shape of the protruding part 2c, and the outer edge shape of the pressing part 3 and pouring part 4 in the vertical direction is smaller than the inner edge shape of the wide part 2b and the protruding part 2c of the storage device 2.

Then, the support tool 1 is rotated approximately 180 degrees on a horizontal plane about the conductive pipe 5 of the dispenser so that the support hole 1b is located on the upper surface KFa of the paper container KF.
続いて、押圧部３を下方に押し、導通管５の上端付近に形成された螺子構造が、係止部６の螺子構造と接する位置まで移動させた後、押圧部３を導通管５とともに回転させて、導通管５の螺子構造と係止部６の螺子構造を螺合させて、係止部６を押圧部の内部に収容する。この際、注出部４の先端が支持孔１ｂの方を向くように調整する。この状態で、突出部２ｃが注出部４側を向くようにして、押圧部３と注出部４を覆うようにして、貯留具２を被せる。図６は、貯留具２で押圧部３と注出部４を覆った状態を示す斜視図である。図６に示すように、省スペース化してコンパクトな状態で、貯留具２を載置することができる。 Subsequently, the pressing part 3 is pushed downward and moved to a position where the screw structure formed near the upper end of the conduit tube 5 contacts the screw structure of the locking part 6, and then the pressing part 3 is rotated together with the conduit tube 5. Then, the screw structure of the conduction tube 5 and the screw structure of the locking part 6 are screwed together, and the locking part 6 is housed inside the pressing part. At this time, the tip of the spouting part 4 is adjusted so as to face the support hole 1b. In this state, the storage tool 2 is placed over the pressing part 3 and the spouting part 4 so that the protruding part 2c faces the spouting part 4 side.

＜＜液体注出具の装着＞＞
次に、紙容器ＫＦへの液体注出具の装着方法について説明する。図５は、液体の内容物を収容した紙容器収容製品の外観を示す斜視図である。図５に示すように、紙容器収容製品は、フラットトップ型の紙容器ＫＦの内部に内容物を充填した後、注出口ＫＦｃを覆い、注出口ＫＦｃの外面の螺子構造とキャップＣＰの内面の螺子構造を螺合させることにより、キャップＣＰを装着したものとなっている。ディスペンサーを備えた液体注出具と別体とすることで、図５に示したような簡易な構造で、低コストで商品の供給が可能となる。
<<Installing the liquid dispensing tool>>
Next, a method of attaching the liquid pouring tool to the paper container KF will be explained. FIG. 5 is a perspective view showing the appearance of a paper container containing product containing liquid contents. As shown in FIG. 5, the product stored in the paper container fills the inside of the flat-top paper container KF with contents, and then covers the spout KFc, and the threaded structure on the outer surface of the spout KFc and the inner surface of the cap CP. The cap CP is attached by screwing the screw structures together. By making it separate from the liquid pouring tool equipped with a dispenser, it becomes possible to supply products at low cost with a simple structure as shown in FIG.
内容物である液体を計量しながら注出するため、別体の液体注出具を紙容器収容製品の紙容器ＫＦに装着する。紙容器収容製品が、図５に示したような簡易な構造で販売されている場合には、この装着作業は、液体注出具を所持し、紙容器収容製品を購入した消費者が行うことになる。装着作業としては、まず、キャップＣＰを回して、紙容器ＫＦの注出口ＫＦｃから取り外す。そして、液体注出具のパイプＰＡの先端から注出口ＫＦｃの内側に挿入し、液体注出具のポンプＰが紙容器ＫＦの内部に達するよう挿入する。そして、係止部６の内面の螺子構造と注出口ＫＦｃの外面の螺子構造を螺合させる。これにより、液体注出具が紙容器ＫＦに装着される。このようにして、液体注出具を備えた液体入り紙容器液体入り紙容器が得られる。 In order to dispense the liquid content while measuring it, a separate liquid dispensing tool is attached to the paper container KF of the product housed in the paper container. If the product contained in a paper container is sold with a simple structure as shown in Figure 5, this installation work must be carried out by the consumer who owns the liquid dispensing tool and has purchased the product contained in the paper container. Become. As for the mounting operation, first, the cap CP is turned and removed from the spout KFc of the paper container KF. Then, insert the liquid spouting tool from the tip of the pipe PA into the inside of the spout KFc so that the pump P of the liquid spouting tool reaches the inside of the paper container KF. Then, the threaded structure on the inner surface of the locking portion 6 and the threaded structure on the outer surface of the spout KFc are screwed together. Thereby, the liquid pouring tool is attached to the paper container KF. In this way, a liquid-filled paper container and a liquid-filled paper container equipped with a liquid pouring tool are obtained.
計量しながら内容物の注出を行う場合には、導通管５の外面に形成された螺子構造と、係止部６の内面の螺子構造の螺合を外し、押圧部３を上方に移動させるとともに、注出部４を紙容器ＫＦの外方に向ける。さらに、支持具１を注出部４の延伸方向に向ける。さらに、貯留具２の開口面を上にして、幅狭部２ａを支持孔１ｂに通すようにして、貯留具２を支持具１に載置する。このときの状態が図１、図２に示したような状態である。 When dispensing the contents while measuring, unscrew the threaded structure formed on the outer surface of the conduit tube 5 and the threaded structure formed on the inner surface of the locking part 6, and move the pressing part 3 upward. At the same time, the spouting part 4 is directed toward the outside of the paper container KF. Furthermore, the support 1 is directed in the direction in which the pouring section 4 extends. Furthermore, the storage device 2 is placed on the support tool 1 with the opening surface of the storage device 2 facing upward and the narrow portion 2a passing through the support hole 1b. The state at this time is as shown in FIGS. 1 and 2.
消費者は、図１、図２に示したような状態で押圧部３を押し下げることにより、ポンプ７が作用し、パイプ８を通って引き上げられた液体を、注出部４から注出する。注出された液体は、注出部４から落下し、貯留具２内に貯留される。消費者は、注出部４を何回か押して、その都度内容物を注出し、貯留具２の側面に設けられた目盛を目安にして、貯留具２内に適量を取得することができる。 When the consumer presses down the pressing part 3 in the state shown in FIGS. 1 and 2, the pump 7 operates and the liquid drawn up through the pipe 8 is poured out from the spouting part 4. The poured liquid falls from the pouring part 4 and is stored in the storage device 2. The consumer can press the pouring part 4 several times to pour out the contents each time, and obtain the appropriate amount into the storage device 2 using the scale provided on the side of the storage device 2 as a guide.
液体注出具を装着した状態の紙容器収容製品を市場に流通させて販売することも可能である。すなわち、図１、図２に示したような状態の液体注出具付き紙容器収容製品を販売することができる。ただし、実際の流通時には、場所をとらずにコンパクトに収納するため、図６に示したように、紙容器ＫＦの上面ＫＦａ側においては、支持具１、貯留具２、押圧部３、注出部４が、紙容器ＫＦの上面ＫＦａの範囲に収まり、押圧部３、注出部４が貯留具２の内部に収まった状態とすることが好ましい。 It is also possible to distribute and sell a product housed in a paper container with a liquid pouring tool attached to the market. That is, it is possible to sell a product housed in a paper container with a liquid pouring device in the state shown in FIGS. 1 and 2. However, during actual distribution, in order to store the paper container compactly without taking up much space, as shown in FIG. It is preferable that the portion 4 is within the range of the upper surface KFa of the paper container KF, and the pressing portion 3 and the pouring portion 4 are within the storage device 2.
図１、図２に示したような使用時の状態から、図６に示したような収納時の状態に移行するためには、以下のように行う。まず、図１に示したような注出可能状態から、貯留具２を支持具１から外す。そして、支持具１をディスペンサーの導通管５を軸として略１８０°回転させて支持孔１ｂが紙容器ＫＦの上面ＫＦａに位置する状態とする。続いて、押圧部３を下方に押し、導通管５の上端付近に形成された螺子構造が、係止部６の螺子構造と接する位置まで移動させた後、押圧部３を導通管５とともに回転させる。これにより、導通管５の螺子構造と係止部６の螺子構造を螺合させて、係止部６を押圧部の内部に収容する。この際、注出部４の先端が支持孔１ｂの方を向くように調整する。この状態で、突出部２ｃが注出部４側を向くようにして、押圧部３と注出部４を覆うようにして、貯留具２を被せる。これにより、図６に示すように、省スペース化してコンパクトな状態で、貯留具２を載置することができる。図６のように、貯留具２を押圧部３と注出部４に被せた状態とすることにより、液体注出具付き紙容器収容製品を販売等で流通させる際に、多数の製品を収納し易くなるという効果がある。 In order to shift from the state in use as shown in FIGS. 1 and 2 to the state in storage as shown in FIG. 6, the following steps are performed. First, the storage device 2 is removed from the support device 1 from the pourable state as shown in FIG. Then, the support tool 1 is rotated approximately 180 degrees around the conductive tube 5 of the dispenser so that the support hole 1b is located on the upper surface KFa of the paper container KF. Subsequently, the pressing part 3 is pushed downward and moved to a position where the screw structure formed near the upper end of the conduit tube 5 contacts the screw structure of the locking part 6, and then the pressing part 3 is rotated together with the conduit tube 5. let Thereby, the screw structure of the conduction tube 5 and the screw structure of the locking part 6 are screwed together, and the locking part 6 is housed inside the pressing part. At this time, the tip of the spouting part 4 is adjusted so as to face the support hole 1b. In this state, the storage tool 2 is placed over the pressing part 3 and the spouting part 4 so that the protruding part 2c faces the spouting part 4 side. Thereby, as shown in FIG. 6, the storage device 2 can be placed in a space-saving and compact state. As shown in FIG. 6, by putting the storage device 2 over the pressing part 3 and the spouting part 4, it is possible to store a large number of products when distributing products stored in paper containers with a liquid spouting tool for sale. This has the effect of making it easier.

なお、フラットトップ型の紙容器ＫＦにおいて、熱接着性樹脂層の膜厚としては、２０～２００μｍの範囲が好ましく、２５～１００μｍの範囲がより好ましい。膜厚が、２５μｍ未満であると、炙りピンホールが発生し易い傾向にあることから好ましくなく、２００μｍを越えると、紙容器の底面や上面の成形性が非常に悪くなることから好ましくないものである。 In the flat-top paper container KF, the thickness of the thermoadhesive resin layer is preferably in the range of 20 to 200 μm, more preferably in the range of 25 to 100 μm. If the film thickness is less than 25 μm, it is undesirable because pinholes tend to occur easily, and if it exceeds 200 μm, the formability of the bottom and top surfaces of the paper container becomes extremely poor, which is undesirable. be.
