Conventionally, when removing a built-in agent in a container, a dispensing nozzle and an opening part are integrally formed in a container that is repeatedly removed little by little by removing a screw cap, or in a flexible container bottle by blow molding or injection molding. There is a break-opening type container (for example, an ampoule) having an opening made of a lid. In the opening portion of the container, a communication port that communicates the outside and the inside of the container serves as a spout for the built-in agent. Further, the opening portion of the opening portion has a circular shape, and usually the lid is held by fingers or the like, and is opened by screw cutting or bending operation. Moreover, it sometimes cut with a cutter such as a cutter or scissors.
JP 2000-41486 A.

この従来構造では、ノズルキャップ20の指押桿aを、指押しすることによる曲折により、ノズル管を容易に切断できる。しかし、この指押しすることによる曲折操作にあっては、指や衣服などに容器内蔵の薬剤を付着させてしまう場合があった。さらに、容器の使用に際して、操作が手間取るという問題があった。以下、具体的に説明する。
まず、指等に薬剤が付着する問題が生ずるのは、ボトル10内の樹幹注入薬剤が、ノズルキャップ20内にも溜まっていることによるものであった。ノズルキャップ20内に薬剤が溜まっている状態で指押桿aを指押しで曲折すると、曲折と同時に薬剤が外部に飛散し、指や衣服に薬剤を付着させてしまうものであった。この、ノズルキャップ20内にも薬剤が溜まっているのは、容器の製造段階や流通段階やユーザー購入段階や使用段階で、容器が横向きや天地逆向き状態となった時に、さらに運搬等の振動が加わった時に、薬剤がボトル10からノズルキャップ20内にも一部移動し、移動した薬剤がノズルキャップ20内の空気と置き換わってしまうためであった。特に、ノズルキャップ20内側が細いと薬剤の毛細管力が強くなるので、ノズルキャップ20を上向きにしても、薬剤がボトル側に容易に移動しないで留まってしまうものであった。
この薬剤付着問題にて、無害な液の場合には、顕著な問題とはならないが、容器内蔵剤が劇薬等の場合には、指に障害を生じさせるとか、衣服に穴をあけてしまうとかの問題があった。また、薬剤ではなく、補充インキ等の発色の鮮やかなインキの場合には、指や衣服を汚染させてしまうという問題があった。
次に、容器使用に際しての、操作が手間取るという問題は、一旦、ノズルキャップ20の指押桿aを指押し曲折し、ノズルキャップ20を容器から切離した後、樹幹に空けた孔に容器を挿入しなければならず面倒なものであった。特に、容器が可撓性の場合には、ノズルキャップ20を切離した後に誤って容器を強く押し過ぎて、内蔵の薬剤をこぼしてしまうリスクもある。
本発明は、上記の問題、即ち、開封操作での容器内蔵剤による指や衣服等への付着を低減させ、且つ、開封操作を簡略にすると共に、取り扱い易い破断開封型の容器を提供することを課題とする。
In this conventional structure, the nozzle tube can be easily cut by bending the finger pressing lever a of the nozzle cap 20 by finger pressing. However, in the bending operation by pushing the finger, there is a case where the medicine contained in the container is adhered to the finger or clothes. Furthermore, there is a problem that the operation is troublesome when the container is used. This will be specifically described below.
First, the problem that the drug adheres to the finger or the like occurs because the trunk injection drug in the bottle 10 is also accumulated in the nozzle cap 20. When the finger pusher a is bent with a finger while the medicine is accumulated in the nozzle cap 20, the medicine is scattered to the outside at the same time as the bending, and the medicine adheres to the fingers and clothes. The medicine is also accumulated in the nozzle cap 20 when the container is in the horizontal or upside down state during the container manufacturing stage, distribution stage, user purchase stage or use stage. This is because a part of the medicine also moves from the bottle 10 into the nozzle cap 20 and the moved medicine is replaced with air in the nozzle cap 20. In particular, if the inside of the nozzle cap 20 is thin, the capillary force of the drug becomes strong. Therefore, even if the nozzle cap 20 faces upward, the drug does not easily move to the bottle side and remains.
In the case of innocuous liquids due to this drug adhesion problem, it does not become a significant problem. However, if the built-in agent is a powerful drug, it may cause a finger injury or a hole in the clothes. There was a problem. In addition, in the case of brightly colored ink such as replenishment ink instead of chemicals, there is a problem that fingers and clothes are contaminated.
Next, the problem of troublesome operation when using the container is that the finger pressing rod a of the nozzle cap 20 is once pushed and bent, and after the nozzle cap 20 is separated from the container, the container is inserted into the hole opened in the trunk. It was a hassle to do. In particular, when the container is flexible, there is also a risk that the container is accidentally pushed too much after the nozzle cap 20 is separated and the built-in medicine is spilled.
The present invention provides a break-open container that reduces the above-mentioned problems, that is, adhesion to fingers, clothes, and the like due to the container built-in agent during the opening operation, simplifies the opening operation, and is easy to handle. Is an issue.

本発明は、開口部と収納部を有したボトル前方に、略筒状の前方が閉じたノズルを固着した破断開封型の容器に於いて、前記ノズルには先端より突起部を設け、この突起部の後方には前記突起部の周囲より拡大した周囲を有する筒部を設け、かつ、前記突起部と筒部とを連結する薄肉状の薄膜部を設けたことを要旨とする。   The present invention relates to a break-opening container in which a substantially cylindrical front-closed nozzle is fixed to the front of a bottle having an opening and a storage portion. The gist is that a cylindrical portion having a periphery enlarged from the periphery of the projection portion is provided behind the projection portion, and a thin thin film portion for connecting the projection portion and the cylindrical portion is provided.

本発明は、開口部と収納部を有したボトル前方に、略筒状の前方が閉じたノズルを固着した破断開封型の容器に於いて、前記ノズルには先端より突起部を設け、この突起部の後方には前記突起部の周囲より拡大した周囲を有する筒部を設け、かつ、前記突起部と筒部とを連結する薄肉状の薄膜部を設けたので、容器の開封操作での容器内蔵剤による指や衣服等への付着を低減させ、開封操作を簡略にすると共に、取り扱い易くする容器を提供することができる。   The present invention relates to a break-opening container in which a substantially cylindrical front-closed nozzle is fixed to the front of a bottle having an opening and a storage portion. Since a cylindrical portion having a periphery expanded from the periphery of the protruding portion is provided behind the protruding portion, and a thin thin film portion that connects the protruding portion and the cylindrical portion is provided, the container in the opening operation of the container It is possible to provide a container that reduces adhesion to fingers, clothes, and the like by a built-in agent, simplifies the opening operation, and facilitates handling.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show a first embodiment. FIG. 1 is a front view showing the rear of the container in cross section, FIG. 2 is an enlarged cross-sectional view of the side surface of the main part of FIG. 1, and FIG. 3 is a use state diagram of FIG.
Reference numeral 1 is a substantially cylindrical bottle formed by a direct blow molding method using a polypropylene resin material (manufactured by Nippon Polypro Co., Ltd., EA7A of Novatec PP) which is a flexible material. The bottle 1 is provided with an opening 1a that opens in a cylindrical shape from the front (upper in the figure), a storage 1b that stores the medicine is provided behind the bottle 1 and is dotted in two places on the left and right sides of the rear end corner. A recessed point 1c is provided.
A nozzle 2 formed by an injection molding method using a polypropylene resin material (manufactured by Nippon Polypro Co., Ltd., Novatec PP) covering the opening 1a and extending forward is provided. The nozzle 2 includes a disc-shaped lid portion 2a that hangs down so as to cover the opening 1a of the bottle 1, a thin cylindrical tube portion 2b that extends forward in the axial center of the lid portion 2a, and a tube portion 2b. A protrusion 2c protruding forward is provided. Two cutout portions 2d that are cut out in a curved shape are provided at the tip of the cylindrical portion 2b. The protruding portion 2c is provided in the shape of a bottomed cylinder having a closed tip, and a thin film portion 2e is provided so as to extend from the outer periphery of the rear end thereof and to be connected to a midway position before and after the inner periphery of the cylindrical portion 2b. A space S larger than the outer diameter of the protruding portion 2c is provided behind the thin film portion 2e inside the cylindrical portion 2b.
On the back surface of the lid portion 2a of the nozzle 2 is provided with a convex rib having an entire circumference extending slightly rearward so as to come into contact with the opening 1a of the bottle 1 on the entire circumference. The convex ribs of the lid portion 2a are provided for joining the bottle 1 and the nozzle 2 by an ultrasonic welding method or a low vibration welding method.
The materials of bottle 1 and nozzle 2 include anti-oxidation, moisture absorption prevention of powder, oil-based solvent, aqueous solvent, acidity, alkalinity, etc. Depending on the purpose of use, such as the appearance of the appearance, it may be selected from thermoplastic resins.
For example, in a single resin material of thermoplastic resin, acrylonitrile / styrene resin, acrylonitrile / butadiene / styrene resin, polyvinyl chloride resin, polyacetal resin, polyamide resins (PA6 / PA66 / PA610 / PA11 / PA12), polyarylate resin , Thermoplastic elastomers (urethane, olefin, styrene, polyamide, polyester, nitrile), polyether ether ketone, polysulfone resin, low density polyethylene, high density polyethylene, linear low density polyethylene, polyethylene terephthalate , Polycarbonate resin, polystyrene resin, polyphenylene ether resin, polyphenylene sulfide resin, polybutadiene resin, polybutylene terephthalate resin, polyethylene naphthalate Resins, polypropylene resins, methacrylic resins, and the like. In addition, for the purpose of improving heat resistance, cold resistance, impact resistance, etc., a polymer alloy material obtained by mixing these various resin materials can be used, or the characteristics of each additive can be modified. Furthermore, once the products used in the market are separated for each molding material, recycled molding materials that have been recycled and molding materials (off-grade) that are not specified by the material manufacturer can also be used. Further, a plant drug container or the like used in the soil may be formed of a biodegradable resin so that the container is naturally decomposed after the built-in agent is supplied.
For use in medicines and hygiene agents, it can be molded using a material in which an antibacterial agent is kneaded in advance. There are organic and inorganic antibacterial agents, but inorganic ones are preferred over organic ones. As inorganic substances, silver, copper, zinc, copper oxide, etc., and these substances are oxidized. Examples include those adsorbed and fixed on inorganic fine particles such as silicon and calcium carbonate.

作用について図3を用いて説明する。図3の符号Wは樹木の縦断面を示し、符号Dは樹木Wに開けた容器のノズル2の外径値のドリル穴を示す。符号O1はドリル穴Dの一般的なドリルによる120度の円錐形の底面であり、且つ、容器1のノズル2を挿入した時のノズル2の押し当て面を示す。
未開封状態の容器のノズル2を、樹木Wのドリル穴Dに挿入する。さらに、ノズル2を押し当て面O1に向けて押し込む。すると、継続した押し込み力により、押し当て面O1に容器の突起部2c先端が接触すると同時に、薄膜部2eが破断し、突起部2cがノズル2の後方の空間部Sに押し込まれる。この時、突起部2cの前方を囲むように筒部2bを設けているので、突起部2cを押し込む際の軸心に対する左右の振れが生じない。薄膜部2eが破断した部位が破断口(破断開封口)Hとなり、容器の内蔵剤が破断口Hを通過し、筒部2bの先端の切り欠き部2dからドリル穴Dの押し当て面O1に向け吐出する。
容器のボトル1を可撓性に設けて、内蔵剤浸透性の早い樹木Wならば、ボトル1を押圧して短期に内蔵剤を注入できる。また、容器のボトル1の上方にある凹点1cに針を突き刺して開口させれば、自然落滴で時間をかけて樹木Wに内蔵剤を注入できる。
以上のように、樹木外部での容器開封操作が不要で、樹木Wのドリル穴Dの略密閉空間内部で容器のノズル2の挿入と同時に容器を開封できるので、容器内蔵剤による指や衣服等への付着を低減させうるものである。また、容器使用に際しての操作を簡略にすることができるものである。
また、コンクリート床面や大きめの石などの硬い略平滑な面に、容器のノズル2の先端を押し付けての開封でも、開封部を指で把持しなくて良く、容器保持位置と開封部の距離が離れているので、内蔵剤の開封飛散による手や衣服への付着を低減できるものである。
ノズル2の筒部2bの外周に雄ねじ部を設け、筒部2bの外径より樹木のドリル穴Dを僅かに小さく開けて、容器のノズル2を捻じ込みながらドリル穴Dに挿入する(セルフタッピング)こともできる。かかる場合には、容器のノズル2の挿入速度をゆっくりすることができ、ノズル2と樹木Wの密着性も高まるので、内蔵剤の樹木W外部への滲出を低減させることができ、且つ、容器を樹木Wから外れ難くすることができる。
ボトル1の内蔵量が少ない等の容器で、ボトル1径がノズル2径と略同径の容器に於いては、ノズル2の後方内面に、ボトル1との固着部を設けても良い。
The operation will be described with reference to FIG. 3 indicates a vertical section of the tree, and D indicates a drill hole having an outer diameter value of the nozzle 2 of the container opened in the tree W. Reference numeral O <b> 1 is a conical bottom surface of 120 degrees by a general drill in the drill hole D, and indicates a pressing surface of the nozzle 2 when the nozzle 2 of the container 1 is inserted.
The nozzle 2 of the unopened container is inserted into the drill hole D of the tree W. Further, the nozzle 2 is pushed toward the pressing surface O1. Then, due to the continuous pressing force, the tip of the protruding portion 2c of the container comes into contact with the pressing surface O1, and at the same time, the thin film portion 2e is broken, and the protruding portion 2c is pushed into the space S behind the nozzle 2. At this time, since the cylindrical portion 2b is provided so as to surround the front of the protruding portion 2c, there is no left-right deflection with respect to the axial center when the protruding portion 2c is pushed. The portion where the thin film portion 2e is broken becomes a breakage opening (breakage opening) H, and the internal agent of the container passes through the breakage opening H, and from the notch 2d at the tip of the cylindrical portion 2b to the pressing surface O1 of the drill hole D. Dispense toward.
If the bottle 1 of the container is provided with flexibility and the tree W has a high built-in agent permeability, the bottle 1 can be pressed to inject the built-in agent in a short time. Moreover, if a needle is pierced and opened at the concave point 1c above the bottle 1 of the container, the internal agent can be injected into the tree W over time with natural dropping.
As described above, it is not necessary to open the container outside the tree, and the container can be opened simultaneously with the insertion of the nozzle 2 of the container inside the substantially sealed space of the drill hole D of the tree W. Adhesion to the surface can be reduced. In addition, the operation when using the container can be simplified.
Also, even when opening the container by pressing the tip of the nozzle 2 on a hard, substantially smooth surface such as a concrete floor or a large stone, it is not necessary to hold the opening with a finger, and the distance between the container holding position and the opening Therefore, adhesion to the hands and clothes due to opening and scattering of the internal agent can be reduced.
A male screw part is provided on the outer periphery of the cylindrical part 2b of the nozzle 2, a drill hole D of a tree is made slightly smaller than the outer diameter of the cylindrical part 2b, and the nozzle 2 of the container is inserted into the drill hole D while being screwed (self-tapping). You can also In such a case, the insertion speed of the nozzle 2 of the container can be reduced, and the adhesion between the nozzle 2 and the tree W can be increased, so that the exudation of the internal agent to the outside of the tree W can be reduced, and the container Can be made difficult to remove from the tree W.
In a container having a small amount of bottle 1 or the like in which the diameter of the bottle 1 is substantially the same as the diameter of the nozzle 2, a fixing portion with the bottle 1 may be provided on the rear inner surface of the nozzle 2.

図4に第二実施例の要部断面図を示す。
第一実施例との差異事項は、有底円筒状のキャップ3をノズル2先端に被せたことである。キャップ3は、突起部2cが誤って押し込まれないための保護部材であり、かつ、無害な内蔵剤を繰り返し使用する場合の密封部材でもある。一度の開封で使い切る容器では、キャップ3はパイプ形等にして、密閉性がなくても良い。このキャップ3をノズル2とは異なる樹脂材で成形し(例えば低密度ポリエチレン等)、キャップ3をノズル2に被せた状態で、ノズル2とボトル1を超音波溶着法で接合しても良い。
FIG. 4 shows a cross-sectional view of the main part of the second embodiment.
The difference from the first embodiment is that a bottomed cylindrical cap 3 is placed on the tip of the nozzle 2. The cap 3 is a protective member for preventing the protrusion 2c from being pushed in by mistake, and is also a sealing member for repeatedly using a harmless built-in agent. In a container that can be used up once by opening, the cap 3 may have a pipe shape or the like, and may not have a sealing property. The cap 3 may be formed of a resin material different from that of the nozzle 2 (for example, low density polyethylene), and the nozzle 2 and the bottle 1 may be joined by an ultrasonic welding method with the cap 3 placed on the nozzle 2.

作用について図6を用いて説明する。図6はインキ補充可能な略円柱形の、内部には押し当て面がある筆記具14へのインキ補充説明図である。
筆記具14の前方(図下方)には、ペン先(図示略)と、ペン先周囲を保護する保護キャップ(図示略)が取り付けられている。筆記具14の後方(図上方)には、着脱自在な尾栓(図示略)があり、尾栓周囲の筆記具14後端には開端部14aがあり、開端部14aの軸心奥側(図下方)に小径の補充口14bがある。さらに、補充口14bの軸心奥側には水平面形の押し当て面O2を有した筒状の中体15がある。筆記具14の補充口14bの奥側には、インキ収容可能な密閉空間がある。尚、ノズル12の筒部12bの外径は、筆記具14の補充口14bと密接するように設けている。
ここで、インキ内蔵の容器を用いて、インキを消費した筆記具14にインキ補充するには、まず、筆記具14を倒立させ筆記具14の後端に止着した尾栓を外し、筆記具14の後方を開口させる。次に、容器のノズル12を挿入する。さらに、ノズル12を押し当て面O2に向けて押し込む。すると、継続した押し込み力により、押し当て面O2に容器の突起部12c先端が接触すると同時に、薄膜部12eが破断し突起部12cがノズル12の後方の空間部Sに押し込まれる。この薄膜部12eが破断した部位が破断口Hとなり、容器内のインキが破断口Hを通過し、筒部12b先端の切り欠き部12dから筆記具14の押し当て面O2に向け吐出する。ここで、ボトル11の収納部11bを押すと、インキを連続して筆記具14に補充できる。容器のインキ内蔵量が多い場合には、ボトル11の収納部11bを押し一定量のインキを補充後、ボトル11の収納部11bの押圧を解除すると、筆記具14内の空気が容器側に吸い込まれる。このボトル11の収納部11bの押す・戻す操作を繰り返すと容器のインキが全量補充される。
作用は第一実施例と同様に、筆記具14の外部での容器開封操作が不要で、筆記具14内部の密閉空間内で容器を開封できるので、インキによる指や衣服等への付着汚れが低減される。また、容器の使用に際しての操作を簡略にすることができるものである。
ここで、筆記具にインキを補充する良好な条件があることが判明した。つまり、筆記具14の押し当て面O2に容器のノズル12先端を押し当てて開封させる。即ち、容器12を押し込む時の薄膜部12eの破断荷重には、適度の範囲があるということである。これは、インキ補充される筆記具14を片手に保持して、他方の片手で容器を保持してのインキ補充操作となるため、薄膜部12cの破断荷重が強すぎると、筆記具14の保持力も過度に要し、インキ補充操作が困難となることである。尚、破断荷重が低い場合は、容器の自重で破壊される程の低い荷重で破断されない限り許容できる
そこで、第三実施例から第六実施例の薄膜部12eの破断力と、筆記具14へのインキ補充容易性を、第一比較例と第二比較例と共に、各々10個の試料を用いて試験した。また、薄膜部12eが薄いと、成形樹脂流動性が阻害され、特に、突起部12cへの樹脂未充填(ショート)となるので、ノズル12の部品成形性も併せて試験した。
インキ補充容易性は以下のように評価した。
○;容易に、筆記具14にインキを補充できる。
△;女性や児童では、筆記具14にインキを補充するのが多少困難となる。
×;女性や児童では、筆記具14にインキを補充するのが困難。
(インキ補充操作を誤って、インキ汚染恐れがある。)
ノズル12の成形性は以下のように評価した。
○;特に問題なし。
△;開封操作は可能ではあるが、突起部12cに僅かなショートが生じる。
×;開封操作が不可能な程、突起部12cがショートとなる。
評価の結果は以下のようであった。

以上より、薄膜部12cの破断荷重が56.4Nでは、インキ補充操作が困難となること、及び、薄膜部厚さが0.02mmでは成形不良となることが判明した。
The operation will be described with reference to FIG. FIG. 6 is an explanatory diagram of ink replenishment to the writing instrument 14 having a substantially cylindrical shape capable of ink replenishment and having a pressing surface inside.
A pen tip (not shown) and a protective cap (not shown) for protecting the periphery of the pen tip are attached to the front of the writing instrument 14 (downward in the drawing). There is a detachable tail plug (not shown) behind the writing instrument 14 (not shown), and there is an open end 14a at the rear end of the writing instrument 14 around the tail plug. ) Has a small-diameter replenishment port 14b. Further, a cylindrical inner body 15 having a horizontal pressing surface O2 is provided on the inner side of the replenishing port 14b. On the back side of the replenishing port 14b of the writing instrument 14, there is a sealed space in which ink can be stored. The outer diameter of the cylindrical portion 12b of the nozzle 12 is provided so as to be in close contact with the replenishing port 14b of the writing instrument 14.
Here, in order to replenish the writing instrument 14 that has consumed ink using the ink-containing container, first, the writing instrument 14 is turned upside down and the tail plug attached to the rear end of the writing instrument 14 is removed. Open. Next, the nozzle 12 of the container is inserted. Further, the nozzle 12 is pushed toward the pressing surface O2. Then, due to the continuous pressing force, the tip of the protruding portion 12c of the container comes into contact with the pressing surface O2, and at the same time, the thin film portion 12e is broken and the protruding portion 12c is pushed into the space S behind the nozzle 12. A portion where the thin film portion 12e is broken becomes a breaking port H, and the ink in the container passes through the breaking port H and is discharged toward the pressing surface O2 of the writing tool 14 from the notch portion 12d at the tip of the cylindrical portion 12b. Here, when the container 11b of the bottle 11 is pushed, the ink can be replenished to the writing instrument 14 continuously. When the amount of ink contained in the container is large, after the storage portion 11b of the bottle 11 is pushed and a certain amount of ink is replenished, the pressure in the storage portion 11b of the bottle 11 is released, and the air in the writing instrument 14 is sucked into the container side. . When the operation of pushing / returning the storage portion 11b of the bottle 11 is repeated, the ink in the container is completely replenished.
As in the first embodiment, the container does not need to be opened outside the writing instrument 14, and the container can be opened in the sealed space inside the writing instrument 14, so that dirt on the fingers, clothes, etc. due to ink is reduced. The In addition, the operation when using the container can be simplified.
It has now been found that there are good conditions for replenishing the writing instrument with ink. That is, the tip of the nozzle 12 of the container is pressed against the pressing surface O2 of the writing instrument 14 to be opened. That is, the breaking load of the thin film portion 12e when the container 12 is pushed in has an appropriate range. This is an ink replenishment operation in which the writing tool 14 to be refilled with ink is held in one hand and the container is held with the other hand, so if the breaking load of the thin film portion 12c is too strong, the holding power of the writing tool 14 is excessive. Therefore, the ink replenishment operation becomes difficult. In addition, when the breaking load is low, it is acceptable as long as it is not broken at such a low load that it is broken by the dead weight of the container. Therefore, the breaking force of the thin film portion 12e of the third to sixth embodiments and the writing instrument 14 Ink replenishability was tested with 10 samples each along with the first and second comparative examples. Further, if the thin film portion 12e is thin, the molding resin fluidity is hindered, and in particular, the resin does not fill (short) the protrusion 12c. Therefore, the moldability of the nozzle 12 was also tested.
Ink replenishment ease was evaluated as follows.
○: The writing instrument 14 can be easily replenished with ink.
Δ: It is somewhat difficult for women and children to replenish the writing instrument 14 with ink.
X: It is difficult for women and children to replenish the writing instrument 14 with ink.
(There is a risk of ink contamination due to incorrect ink replenishment operation.)
The moldability of the nozzle 12 was evaluated as follows.
○: No particular problem.
Δ: Although the opening operation is possible, a slight short circuit occurs in the protrusion 12c.
X: The protrusion 12c becomes short as the opening operation is impossible.
The evaluation results were as follows.
Third Example Breaking average strength 33.6N, ink replenishment ease ○, moldability ○
Fourth Example Breaking average strength 27.1 N, ink replenishment ease ○, moldability Δ
Fifth Example Breaking average strength 49.0N, ink replenishment ease Δ, moldability ○
Sixth Example Breaking average strength 3.8N, ink replenishment ease ○, moldability ○
First Comparative Example Sample for fracture test could not be obtained (formability; x)
Second Comparative Example Breaking average strength 56.4N, Ink replenishment ease x, Formability ○
From the above, it has been found that when the breaking load of the thin film portion 12c is 56.4N, the ink replenishment operation becomes difficult, and when the thin film portion thickness is 0.02 mm, molding failure occurs.

図7と図8に第七実施例を示す。図7は要部断面図を示し、図8は図7の上面図を示す。第三実施例との差異事項は、薄膜部22e後方に、突起部22cに連設する円筒形の内筒部22fを設けている。薄膜部22eの上面に、突起部22cと筒部22b内面を連結する蒲鉾状の3本の連結リブ22gを設けている。また、筒部22b内側には、内筒部22fを含めた突起部22cが納まる空間部Sを設けている。ノズル22は第三実施例のポリプロピレン樹脂と同一グレードで、薄膜部22eの膜厚は0.04mm、連結リブ22gの幅は0.20mmで厚さ0.10mmに設けている。
本実施例も、第三実施例と同様に試験評価した。
第七実施例 破断平均強度30.5N、 インキ補充容易性○、 成形性○
作用は第一実施例と同様であるが、筒部22b内に内筒部22fを設けているので、突起部22cを押し込む時の突起部22cの軸心に対する左右の振れを筒部22b内の薄膜部22e後方で抑制できる。このため、薄膜部22e前方の筒部22bが短くても、突起部22cの倒れが生じなく安定して突起部22cを押し込める。また、薄膜部22eの上面に連結リブ22gを設けているので、その連結リブ22gを介して成形樹脂が主に流れ、突起部22cへの樹脂充填性が高まる。この様に、樹脂充填性が高まるので、前記薄膜部厚さを0.04mmとしても、破断強度を大きく高めないで、突起部22cのショートを向上させうるものである。
尚、ノズル22への樹脂充填性を高めるのに、突起部22cの先端にゲート(ピンゲート)を設けても良い。また、突起部22cの先端と切り欠き部22dの2点にゲートを設けても良い。突起部22cの先端からのピンゲートでは、薄膜部22eの樹脂流動性は軸心から放射状に流れ、特に、ポリプロピレンやポリアセタール樹脂等の結晶性樹脂材料の場合、樹脂配向方向である結晶方向が均等となり、破断強度が高めになる傾向にある。そこで、薄膜部22eの膜厚等を多少、大小に変化させて、薄膜部22eの樹脂流動を乱流状にして樹脂配向を乱れさせることにより、破断強度を低めることもできる。
7 and 8 show a seventh embodiment. 7 shows a cross-sectional view of the main part, and FIG. 8 shows a top view of FIG. The difference from the third embodiment is that a cylindrical inner tube portion 22f connected to the protruding portion 22c is provided behind the thin film portion 22e. On the upper surface of the thin film portion 22e, three hook-shaped connecting ribs 22g for connecting the protrusion 22c and the inner surface of the cylindrical portion 22b are provided. Further, a space portion S in which the protruding portion 22c including the inner cylindrical portion 22f is accommodated is provided inside the cylindrical portion 22b. The nozzle 22 is of the same grade as the polypropylene resin of the third embodiment, the thin film portion 22e has a thickness of 0.04 mm, the connecting rib 22g has a width of 0.20 mm and a thickness of 0.10 mm.
This example was also tested and evaluated in the same manner as the third example.
Seventh Example Breaking average strength 30.5N, ink replenishment ease ○, moldability ○
The operation is the same as in the first embodiment, but since the inner cylindrical portion 22f is provided in the cylindrical portion 22b, the left and right deflection with respect to the axial center of the protruding portion 22c when the protruding portion 22c is pushed in is in the cylindrical portion 22b. It can be suppressed behind the thin film portion 22e. For this reason, even if the cylinder part 22b in front of the thin film part 22e is short, the protrusion 22c does not fall down, and the protrusion 22c can be pushed in stably. Further, since the connecting rib 22g is provided on the upper surface of the thin film portion 22e, the molding resin mainly flows through the connecting rib 22g, and the resin filling property to the protruding portion 22c is improved. As described above, since the resin filling property is improved, even if the thickness of the thin film portion is 0.04 mm, the short-circuit of the protruding portion 22c can be improved without greatly increasing the breaking strength.
Note that a gate (pin gate) may be provided at the tip of the protrusion 22c in order to improve the resin filling property to the nozzle 22. Further, gates may be provided at two points, that is, the tip of the protrusion 22c and the notch 22d. In the pin gate from the tip of the protruding portion 22c, the resin fluidity of the thin film portion 22e flows radially from the axial center. In particular, in the case of a crystalline resin material such as polypropylene or polyacetal resin, the crystal orientation that is the resin orientation direction is uniform. The breaking strength tends to increase. Therefore, the breaking strength can be lowered by changing the film thickness of the thin film portion 22e somewhat to make the resin flow in the thin film portion 22e turbulent and disturbing the resin orientation.

図9〜図11に第八実施例を示す。図9は要部断面図を示し、図10は図9の側面拡大断面図を示し、図11は図9の使用状態図を示す。第一実施例〜第七実施例との差異事項は、ボトル31の開口部31aの外周囲に、外方に突出する全周状の凸周リブ31dを設けている。ノズル32の蓋部32a内周囲には、ボトル31の凸周リブ31dに乗り越え嵌合するように、全周溝状の内周溝32hを設けている。蓋部32aの外周囲には、後述する筆記具34の雌ねじ34cに嵌め合う雄ねじ部32iを設けている。また、ノズル32の突起部32cは、円柱形を斜めに切ったような略斜形に設けていて、その先端は軸心から離れた位置に設けている。さらに、突起部32c内面から筒部32b内面に向け、蒲鉾状の縦リブ32jを突起部32cの先端方向側に設けている。
図11は、第三実施例の筆記具14と類似した筆記具34へのインキ補充の説明図である。筆記具34の後端には開端部34aが形成されており、なだらかな凸曲面形の押し当て面O3を有した筒状の中体35がある。ボトル31の凸周リブ31dとノズル32の内周溝32hを嵌合させているので、ボトル31とノズル32を固着できる。容器と筆記具34は、ノズル32に設けた雄ねじ部32iによりねじ固着させているので、筆記具34に容器のノズル32をゆっくり捻じ込み挿入できる。ゆっくり捻じ込めるので、容器の筆記具34への挿入操作が安定できる。筆記具34に容器のノズル32を挿入すると、ノズル32の突起部32cを略斜形で先端が軸心から離れた形状に設けているので、まず、突起部32c先端が、筆記具34の押し当て面O3の軸心から離れた位置に当接する。さらに容器を筆記具34に捻じ込むと、ノズル32の突起部32cが捻じ込み深さに応じて、縦リブ32jを支点として外周方向に倒れ変形する。突起部32cの倒れ変形が過度になると、薄膜部32eが破断され開封する。筆記具34の押し当て面O3が凸曲面形に形成されているため、平面に比し突起部32cの先端が滑り易い接触となり倒れ変形し易いものとなっている。
以上のように、第一実施例と同様の作用に加えて、ノズル32の薄膜部32eの肉厚が縦リブ32jの反対側(=破断開始側)を薄めにする一方、縦リブ32j側を厚めにすることで、突起部32cの倒れ変形による薄膜部32eの破断開始をより早めることができる。また、結晶性樹脂材料での樹脂流動を乱流状にし、薄膜部32eの破断強度を低めることもできる。
9 to 11 show an eighth embodiment. 9 shows a cross-sectional view of the main part, FIG. 10 shows an enlarged side cross-sectional view of FIG. 9, and FIG. 11 shows a use state diagram of FIG. The difference from the first embodiment to the seventh embodiment is that an outer circumferential protruding rib 31d that protrudes outward is provided on the outer periphery of the opening 31a of the bottle 31. An inner circumferential groove 32h having a circumferential groove shape is provided around the inner periphery of the lid portion 32a of the nozzle 32 so as to get over and fit over the convex circumferential rib 31d of the bottle 31. On the outer periphery of the lid portion 32a, there is provided a male screw portion 32i that fits into a female screw 34c of a writing instrument 34 described later. Further, the protrusion 32c of the nozzle 32 is provided in a substantially oblique shape that is obtained by obliquely cutting a cylindrical shape, and its tip is provided at a position away from the axis. Furthermore, a flange-like vertical rib 32j is provided on the tip direction side of the protrusion 32c from the inner surface of the protrusion 32c toward the inner surface of the cylinder 32b.
FIG. 11 is an explanatory diagram of ink replenishment to the writing instrument 34 similar to the writing instrument 14 of the third embodiment. An open end portion 34a is formed at the rear end of the writing instrument 34, and there is a cylindrical inner body 35 having a gently convex curved pressing surface O3. Since the convex peripheral rib 31d of the bottle 31 and the inner peripheral groove 32h of the nozzle 32 are fitted, the bottle 31 and the nozzle 32 can be fixed. Since the container and the writing instrument 34 are screw-fixed by the male screw portion 32 i provided on the nozzle 32, the container nozzle 32 can be slowly screwed into the writing instrument 34 and inserted. Since it is slowly screwed in, the operation of inserting the container into the writing instrument 34 can be stabilized. When the container nozzle 32 is inserted into the writing instrument 34, the protrusion 32c of the nozzle 32 is provided with a substantially oblique shape and the tip is separated from the axis, so the tip of the protrusion 32c is the pressing surface of the writing instrument 34 first. It abuts at a position away from the axis of O3. When the container is further screwed into the writing instrument 34, the protrusion 32c of the nozzle 32 falls and deforms in the outer circumferential direction with the vertical rib 32j as a fulcrum according to the screwing depth. If the overturning deformation of the protrusion 32c becomes excessive, the thin film portion 32e is broken and opened. Since the pressing surface O3 of the writing instrument 34 is formed in a convex curved surface shape, the tip of the protruding portion 32c becomes a slippery contact as compared with a flat surface, so that it is easy to fall down and deform.
As described above, in addition to the same operation as in the first embodiment, the thickness of the thin film portion 32e of the nozzle 32 makes the opposite side (= break start side) of the vertical rib 32j thinner, while the vertical rib 32j side becomes thinner. By increasing the thickness, the thin film portion 32e can be started to break earlier due to the falling deformation of the protrusion 32c. In addition, the resin flow in the crystalline resin material can be made turbulent to reduce the breaking strength of the thin film portion 32e.

図12〜図13に第九実施例を示す。図12は要部断面図を示し、図13は図12の使用状態を示す。第一実施例〜第八実施例との差異事項は、ノズル42の突起部42cを中空状の略円錐形に設け、その突起部42cの先端は軸心から離れた位置に設けている。筒部42bの先端に斜面形の傾斜部42kを設けている。薄膜部42eも傾斜部42kの面に添うように傾斜状に設けている。薄膜部42eよりは厚肉の厚肉部42lを傾斜部42kの最前方内面から突起部42cの内面に向け連結するように1箇所に設けている。
作用について説明する。ノズル42を机上面Pに押し付けると、まず、ノズル42の軸心から離れた位置で突起部42c先端が当接する。さらに押し付けると、厚肉部42lを支点にして、突起部42cが筒部42b内に倒れ込み変形する。この突起部42cの倒れ込み変形が過度に進むと薄膜部42eが破断し開封する。
以上のように、第一実施例と同様の作用に加えて、ノズル42の薄膜部42eの破断開始位置を厚肉部42lの支点位置より容器側(後方側)に設けているので、突起部42cの倒れ込み変形、即ち、厚肉部42lを支点にした突起部42cの回転移動性が円滑となり、開封操作性が高まるものである。
A ninth embodiment is shown in FIGS. 12 shows a cross-sectional view of the main part, and FIG. 13 shows the state of use of FIG. The difference from the first embodiment to the eighth embodiment is that the projection 42c of the nozzle 42 is provided in a hollow, substantially conical shape, and the tip of the projection 42c is provided at a position away from the axis. A sloped inclined portion 42k is provided at the tip of the cylindrical portion 42b. The thin film portion 42e is also provided in an inclined shape so as to follow the surface of the inclined portion 42k. A thicker portion 42l thicker than the thin film portion 42e is provided at one location so as to be connected from the foremost inner surface of the inclined portion 42k toward the inner surface of the protruding portion 42c.
The operation will be described. When the nozzle 42 is pressed against the desk surface P, first, the tip of the protrusion 42 c comes into contact with the nozzle 42 at a position away from the axis of the nozzle 42. When further pressed, the projecting portion 42c falls into the cylindrical portion 42b and deforms with the thick portion 42l as a fulcrum. When the projecting portion 42c is excessively deformed, the thin film portion 42e is broken and opened.
As described above, since the break start position of the thin film portion 42e of the nozzle 42 is provided on the container side (rear side) from the fulcrum position of the thick portion 42l in addition to the same operation as the first embodiment, 42c falls down, that is, the rotational movement of the protrusion 42c with the thick portion 42l as a fulcrum becomes smooth, and the opening operability is enhanced.

図14〜図15に第十実施例を示す。図14は要部断面図を示し、図15は図14の使用状態を示す。第九実施例との差異事項は、ノズル52の厚肉部52lの軸反対側で、突起部52cの側面の一部が窪む凹曲部52mを設けている。
作用について説明する。ノズル52を天面Qに押し付けると、ノズル52の突起部52cが倒れ込み変形する過程で薄膜部52eが破断する。さらに押し付けると、凹曲部52mが筒部52bの先端に圧接するまで突起部52cが倒れ込み変形(回転移動)する。
以上のように、第九実施例と同様の作用に加えて、ノズル52に凹曲部52mを設けているので、突起部52cの回転移動角度を、より大きくできるものである。
容器は、本実施例で示すように、天面に押し付けての開封もできるものである。このように、どの向きの面に押し付けても開封できるので、内蔵剤の付着影響が少なければ、開封時の押し当て面方向の限定がなく、開封操作は自由度が高いものである。
14 to 15 show a tenth embodiment. FIG. 14 shows a cross-sectional view of the main part, and FIG. 15 shows the use state of FIG. The difference from the ninth embodiment is that a concave curved portion 52m in which a part of the side surface of the protruding portion 52c is recessed is provided on the opposite side of the axis of the thick portion 52l of the nozzle 52.
The operation will be described. When the nozzle 52 is pressed against the top surface Q, the thin film portion 52e is broken in the process in which the protruding portion 52c of the nozzle 52 falls and deforms. When further pressed, the protrusion 52c falls down and deforms (rotates) until the concave curved portion 52m comes into pressure contact with the tip of the cylindrical portion 52b.
As described above, in addition to the same operation as that of the ninth embodiment, since the concave curved portion 52m is provided in the nozzle 52, the rotational movement angle of the protruding portion 52c can be further increased.
As shown in the present embodiment, the container can be opened by being pressed against the top surface. Thus, since it can open even if it presses on the surface of any direction, if there is little adhesion influence of a built-in agent, there will be no limitation of the pressing surface direction at the time of opening, and opening operation has a high freedom degree.

図16〜図18に第十一実施例を示す。図16は要部断面図を示し、図17は図16の使用状態図を示し、図18は図17の上面図を示す。第一実施例〜第十実施例との差異事項は、ノズル62の薄膜部62eの外周囲から前方に向けて突起部62cの先端以上に延びる起立片62nを設けている。その起立片62nは6片の湾曲板状からなり、突起部62cの外周囲に配置している。また、起立片62nの後端で、筒部62bの前端外周に外周溝62oを設けている。
作用について説明する。ノズル62を天面Qに押し付けると、まず、起立片62n先端が当接する。さらに押し付けると、外周溝62oを支点にして起立片62nが花開くように変形する。さらに押し付けると、突起部62cが筒部62bの方向に押し込まれ、薄膜部62eが破断し開封する。起立片62nの変形荷重と突起部62cの破断荷重をバランス良く配分し、総荷重を高くなり過ぎないように設けると良い。
以上のように、第一実施例と同様の作用に加えて、ノズル62に突起部62cの先端以上に延びる起立片62nを設けているので、第二実施例のキャップのように、突起部62cを保護でき、かつ、押し付け操作のみで開封できるものである。
An eleventh embodiment is shown in FIGS. 16 shows a cross-sectional view of the main part, FIG. 17 shows a use state diagram of FIG. 16, and FIG. 18 shows a top view of FIG. The difference from the first embodiment to the tenth embodiment is that an upstanding piece 62n extending beyond the tip of the projection 62c from the outer periphery of the thin film portion 62e of the nozzle 62 to the front is provided. The standing piece 62n has a curved plate shape of six pieces, and is disposed on the outer periphery of the protrusion 62c. Further, an outer peripheral groove 62o is provided on the outer periphery of the front end of the cylindrical portion 62b at the rear end of the standing piece 62n.
The operation will be described. When the nozzle 62 is pressed against the top surface Q, first, the tip of the standing piece 62n comes into contact. When further pressed, the upright piece 62n is deformed so that it blossoms with the outer circumferential groove 62o as a fulcrum. When further pressed, the projecting portion 62c is pushed in the direction of the cylindrical portion 62b, and the thin film portion 62e is broken and opened. The deformation load of the upright piece 62n and the breaking load of the protrusion 62c are preferably distributed in a balanced manner so that the total load does not become too high.
