Description

本発明は、底蓋を設けた外筒と蓋体を設けた内筒からなる密閉容器に関し、特に水溶性の飲料用粉体、各種検体や試料等の小容量の物体を収容するのに適した密閉容器に関する。   The present invention relates to a sealed container comprising an outer cylinder having a bottom lid and an inner cylinder having a lid, and is particularly suitable for accommodating small-volume objects such as water-soluble beverage powder, various specimens and samples. Related to closed containers.

従来から、底蓋を設けた外筒と蓋体を設けた内筒からなる密閉容器は知られているが、底蓋を開放する内筒の下端縁は水平に設けられている。このため従来においては、内筒下端縁の押圧力が底蓋全周にほぼ均等にかかり、押圧力が一定以上になると、底蓋は外筒から完全に分離して脱落する。このように、底蓋が脱落すると、これを回収することが困難となる。そして、密閉容器をボトルキャップとして飲料用ボトル容器に適用する場合には、ボトル容器内に脱落した底蓋を取り出せないので、飲料と一緒に飲み込んでしまう危険性があった。これを避けるために、従来においては、底蓋が外筒から脱落しても回収できるように、底蓋と外筒を連結片で連結している。
特開２００４−１０６８８８号公報 Conventionally, a sealed container comprising an outer cylinder provided with a bottom lid and an inner cylinder provided with a lid is known, but the lower end edge of the inner cylinder that opens the bottom lid is provided horizontally. For this reason, conventionally, the pressing force of the lower end edge of the inner cylinder is applied almost evenly on the entire circumference of the bottom lid, and when the pressing force exceeds a certain level, the bottom lid is completely separated from the outer cylinder and falls off. Thus, when the bottom lid falls off, it becomes difficult to recover it. And when applying a sealed container to a bottle container for drinks as a bottle cap, since the bottom cover which fell in the bottle container cannot be taken out, there existed a possibility of swallowing with a drink. In order to avoid this, conventionally, the bottom cover and the outer cylinder are connected by a connecting piece so that the bottom cover can be recovered even if it drops off from the outer cylinder.
JP 2004-106888 A

ところがこの従来技術によると、連結部材で底蓋と外筒を連結するために、構造が複雑となって、製造コストも増すという不都合があった。本発明は、この不都合を解消した密閉容器を提供することを目的とする。   However, according to this prior art, since the bottom cover and the outer cylinder are connected by the connecting member, there is a disadvantage that the structure becomes complicated and the manufacturing cost increases. An object of this invention is to provide the airtight container which eliminated this inconvenience.

上記目的を達成するために、本発明の請求項１に係る密閉容器は、外筒と内筒で構成される密閉容器であって、外筒は、底面を環状の肉薄部を介して開放可能に設けた底蓋で閉塞し、内周面下部には内径を小径化する内径小径部を設け、外周面上部には雄ねじ部を設けるとともに、外周面の雄ねじ部より下方に係止つば部を設けてなる一方、内筒は、前記外筒内に進退可能で、下部には外径のみを小径化した外径小径部を設け、開放下端面は傾斜して、その縁部を刃状の押圧部となし、上端面は前記外筒の雄ねじ部に螺合する雌ねじ部を設けた蓋体で閉塞し、この蓋体の下端部には複数のブリッジを介して規制環を切り離し可能に設けてなり、前記外筒の雄ねじ部に前記蓋体の雌ねじ部を螺合して蓋体を締め付け方向に回転することにより前記内筒が回転しながら前記外筒内に進入し、前記内筒の外径小径部より上方の部分が前記外筒の内径小径部に緊密に接合すると、密閉状態になるとともに、前記係止つば部が前記規制環を係止して内筒の外筒に対する進入を阻止する一方、前記蓋体をさらに締め付け方向に回転すると前記規制環が切り離されて、内筒は回転しながらさらに外筒内に進入し、その押圧部の当接部分で底蓋の肉薄部を部分的に押圧して破断し、破断部分が一定以上になると底蓋は開放状態となって、肉薄部における押圧部の押圧力が付与されない部分、すなわち肉薄部において押圧部の後端に対応して押圧力がかからない部分は、破断せずに残存するよう構成したものである。   In order to achieve the above object, a sealed container according to claim 1 of the present invention is a sealed container composed of an outer cylinder and an inner cylinder, and the outer cylinder can be opened at the bottom via an annular thin portion. The inner lid is provided with a small inner diameter portion at the lower portion of the inner peripheral surface, a male screw portion at the upper portion of the outer peripheral surface, and a locking collar portion below the male screw portion of the outer peripheral surface. On the other hand, the inner cylinder can be advanced and retracted into the outer cylinder, and the lower part is provided with a small outer diameter part with a reduced outer diameter, the open lower end surface is inclined, and the edge part is shaped like a blade. There is no pressing part, and the upper end surface is closed with a cover provided with an internal thread part that is screwed into the external thread part of the outer cylinder, and a restriction ring is provided at the lower end part of the cover body through a plurality of bridges. And by rotating the lid body in the tightening direction by screwing the female thread portion of the lid body into the male thread portion of the outer cylinder. When the inner cylinder enters the outer cylinder while rotating, and a portion above the small-diameter portion of the inner cylinder is tightly joined to the small-diameter portion of the outer cylinder, the inner cylinder is sealed and the locking collar While the portion locks the restriction ring and prevents the inner cylinder from entering the outer cylinder, when the lid is further rotated in the tightening direction, the restriction ring is disconnected, and the inner cylinder is further rotated while the inner cylinder rotates. And the thin part of the bottom cover is partially pressed and broken at the contact part of the pressing part, and when the broken part exceeds a certain level, the bottom cover is opened and the pressing part of the thin part is pressed. The portion where no pressure is applied, that is, the portion where no pressing force is applied corresponding to the rear end of the pressing portion in the thin portion is configured to remain without breaking.

同じく上記目的を達成するために、本発明の請求項２に係る密閉容器は、上記請求項１に係る密閉容器の構成において、内筒の軸方向に最も短い部分に対応する押圧部、換言すると押圧部の後端に、切り欠きを設けたものである。   Similarly, in order to achieve the above object, the sealed container according to claim 2 of the present invention is a pressing part corresponding to the shortest part in the axial direction of the inner cylinder in the structure of the sealed container according to claim 1, in other words, A notch is provided at the rear end of the pressing portion.

同じく上記目的を達成するために、本発明の請求項３に係る密閉容器は、上記請求項１または請求項２に係る密閉容器の構成において、外筒の係止つば部には、ビン容器首部の雄ねじ部に螺合する雌ねじ部を垂下形成したものである。   Similarly, in order to achieve the above object, a closed container according to a third aspect of the present invention is the closed container according to the first or second aspect, wherein the locking collar portion of the outer cylinder has a bottle container neck. A female screw portion that is screwed into the male screw portion is formed in a hanging manner.

本発明の請求項１に係る密閉容器によれば、内筒の開放下端面を傾斜面とし、その縁部を刃状の押圧部としたので、この押圧部が、蓋体の締め付け方向の回転にともなわれて回転しつつ、底蓋の肉薄部をその当接部分で部分的に押圧して徐々に破断するとともに、底蓋を傾斜に沿って押し開いていき、破断部分が一定以上になると、底蓋は押圧部の押圧力で完全に開く開放状態となり、押圧力がかからない押圧部の後端に対応する底蓋の肉薄部は破断されずに残るので、底蓋は外筒から脱落することがないという効果を奏する。   According to the closed container of the first aspect of the present invention, since the open lower end surface of the inner cylinder is an inclined surface and the edge thereof is a blade-like pressing portion, the pressing portion rotates in the tightening direction of the lid. While rotating, the thin part of the bottom cover is partially pressed at the contact part and gradually broken, and the bottom cover is pushed open along the inclination, and the broken part becomes more than a certain level. Then, the bottom cover opens completely with the pressing force of the pressing part, and the thin part of the bottom cover corresponding to the rear end of the pressing part where no pressing force is applied remains unbroken, so the bottom cover is removed from the outer cylinder. There is an effect that there is nothing to do.

また、本発明の請求項２に係る密閉容器によれば、内筒の最も短い部分に対応する押圧部、すなわち押圧部の後端に、切り欠きを形成したので、底蓋の肉薄部に押圧力をかけない部分を確実に確保して、肉薄部の残存部形成をより確実に行うことができるという効果を奏する。   Further, according to the sealed container of the second aspect of the present invention, the notch is formed in the pressing portion corresponding to the shortest portion of the inner cylinder, that is, the rear end of the pressing portion. There is an effect that the portion where no pressure is applied can be ensured and the remaining portion of the thin portion can be more reliably formed.

さらに、本発明の請求項３に係る密閉容器によれば、ビン容器首部の雄ねじ部に螺合可能な雌ねじ部を内筒の蓋体に設けたので、ビンのキャップに適用して好適であるという効果を奏する。   Furthermore, according to the hermetic container according to claim 3 of the present invention, the internal threaded portion that can be screwed into the external threaded portion of the bottle container neck is provided in the lid of the inner cylinder. There is an effect.

以下、本発明の好適な実施形態を添付図面に基づいて説明する。ここにおいて、図１は内筒と外筒を分離した状態の斜視図、図２は内筒の雄ねじ部と外筒の雌ねじ部を螺合した非密閉状態を示す縦断面図、図３は同じく密閉状態を示す部分拡大縦断面図、図４は樹脂製ビン容器の首部雄ねじ部に外筒の雌ねじ部を螺合した密閉状態の密閉容器を示す正面図、図５は密閉状態の密閉容器を示す縦断面図、図６は内筒の蓋体を回転して規制環を切り離すとともに、底蓋の肉薄部を部分的に破断した状態を示す縦断面図、図７は底蓋の開放状態を示す縦断面図である。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a perspective view in a state where the inner cylinder and the outer cylinder are separated, FIG. 2 is a longitudinal sectional view showing an unsealed state in which the male thread portion of the inner cylinder and the female thread portion of the outer cylinder are screwed together, and FIG. 4 is a partially enlarged longitudinal sectional view showing a sealed state, FIG. 4 is a front view showing a sealed container in which a female screw part of an outer cylinder is screwed into a neck male screw part of a resin bottle container, and FIG. 5 shows a sealed container in a sealed state. FIG. 6 is a longitudinal sectional view showing a state in which the inner ring is rotated to separate the regulating ring and the thin portion of the bottom lid is partially broken. FIG. It is a longitudinal cross-sectional view shown.

図１及び図２に示すように、密閉容器１は、ともに合成樹脂製の外筒２と内筒３からなる。外筒２は、底面を環状の肉薄部４を介して開放可能に設けた底蓋５で閉塞し、内周面下部には内径を小径化する環状突部７とそれに続く小径部６を設け、この環状突部７が内径小径部を構成する。外筒２の外周面上部には雄ねじ部８を設けるとともに、外周面の雄ねじ部８より下方に係止つば部９を設け、この係止つば部９にはビン容器４１の首部４２の雄ねじ部４３（図４参照）に螺合する雌ねじ部１０を垂下形成している。   As shown in FIGS. 1 and 2, the sealed container 1 includes an outer cylinder 2 and an inner cylinder 3 made of synthetic resin. The outer cylinder 2 is closed by a bottom cover 5 provided so that the bottom surface can be opened via an annular thin portion 4, and an annular protrusion 7 for reducing the inner diameter and a subsequent small diameter portion 6 are provided at the lower part of the inner peripheral surface. The annular projection 7 constitutes a small inner diameter portion. A male screw portion 8 is provided on the outer peripheral surface upper portion of the outer cylinder 2 and a locking collar portion 9 is provided below the male screw portion 8 on the outer peripheral surface, and the male screw portion of the neck portion 42 of the bottle container 41 is provided on the locking collar portion 9. A female threaded portion 10 that is screwed into 43 (see FIG. 4) is formed to hang down.

一方、内筒３の外径は、下部を除いて外筒２の環状突部７を除く内径よりも若干小径で、前記環状突部７部分の内径よりは若干大径とし、この環状突部７部分に緊密に接合するよう構成し、また、前記内筒３は前記外筒２内に進退可能である。この内筒３の下部には、外径のみを小径化した外径小径部１１を設け、開放下端面は傾斜して、その縁部は刃状に形成して押圧部１２としている。前記外径小径部１１の下端縁部である押圧部１２において一番高いところ、換言すると内筒３の軸方向の長さで一番短いところに対応する押圧部１２の後端に、切り欠き１３を設けている。   On the other hand, the outer diameter of the inner cylinder 3 is slightly smaller than the inner diameter excluding the annular protrusion 7 of the outer cylinder 2 except for the lower part, and slightly larger than the inner diameter of the annular protrusion 7 part. The inner cylinder 3 can be advanced and retracted into the outer cylinder 2. An outer diameter small diameter portion 11 in which only the outer diameter is reduced is provided at the lower portion of the inner cylinder 3, the open lower end surface is inclined, and the edge portion is formed in a blade shape to form a pressing portion 12. A notch is formed at the rear end of the pressing portion 12 corresponding to the highest portion in the pressing portion 12 which is the lower end edge portion of the outer diameter small diameter portion 11, in other words, the shortest axial length of the inner cylinder 3. 13 is provided.

また、内筒３の上端面は、外筒２の雄ねじ部８に螺合する雌ねじ部１４を内周面に設けた蓋体１５で閉塞し、この蓋体１５の下端部には複数のブリッジ１６を介して規制環１７を切り離し可能に設けている。この規制環１７は、外筒２の雄ねじ部８に前記蓋体１５の雌ねじ部１４を螺合し、前記蓋体１５を締め付け方向に回転して、前記内筒３が回転しながら前記外筒２内に進入すると、これとともに回転移動して係止つば部９に係止し、前記内筒３の前記外筒２に対する進入を阻止する（図４、図５参照）。このとき、前記内筒３の外径小径部１１より上方の部分が、前記外筒２の環状突部７を乗り越えて小径部６に達し、前記環状突部７と緊密に接合して、密閉状態になる（図３、図５参照）。なお、前記蓋体１５をさらに回転するとブリッジ１６が破断して前記規制環１７が切り離され、前記内筒３の前記外筒２に対する進入を許容する。   Further, the upper end surface of the inner cylinder 3 is closed with a cover body 15 provided on the inner peripheral surface with a female thread section 14 screwed into the male thread section 8 of the outer cylinder 2. The restriction ring 17 can be separated through 16. The restriction ring 17 is formed by screwing the female threaded portion 14 of the lid 15 into the male threaded portion 8 of the outer cylinder 2, rotating the lid 15 in the tightening direction, and rotating the inner cylinder 3 while rotating the inner cylinder 3. When it enters 2, it rotates together with this and engages with the locking collar 9, thereby preventing the inner cylinder 3 from entering the outer cylinder 2 (see FIGS. 4 and 5). At this time, the portion above the outer diameter small diameter portion 11 of the inner cylinder 3 gets over the annular projection 7 of the outer cylinder 2 and reaches the small diameter portion 6, and is tightly joined to the annular projection 7 to be sealed. (See FIGS. 3 and 5). When the lid 15 is further rotated, the bridge 16 is broken and the restriction ring 17 is disconnected, allowing the inner cylinder 3 to enter the outer cylinder 2.

続いて、上述のように構成した密閉容器１を、飲料ビン容器に収容したミネラルウォターにインスタントコーヒー粉末を溶解してコーヒーにする場合の使用方法について説明する。まず、図１状態にある外筒２内に、易水溶性のインスタントコーヒーの粉末ａを収容し、この外筒２に内筒３を挿入して、蓋体１５の雌ねじ部１４を外筒２の雄ねじ部８に螺合する（図２参照）。そして、前記蓋体１５を締め付け方向に回転すると、前記内筒３が回転しながら前記外筒２内にさらに進入し、前記内筒３の外径小径部１１より上方の部分が、外筒２の環状突縁７を乗り越えてこれと緊密に接合し、小径部６に達すると、密閉容器１内の粉末ａは外部と遮断され、密閉状態になる（図３参照）。   Next, a method of using the sealed container 1 configured as described above when dissolving instant coffee powder in mineral water accommodated in a beverage bottle container to make coffee will be described. First, the water-soluble instant coffee powder a is accommodated in the outer cylinder 2 in the state of FIG. 1, the inner cylinder 3 is inserted into the outer cylinder 2, and the female thread portion 14 of the lid 15 is attached to the outer cylinder 2. The male screw portion 8 is screwed (see FIG. 2). Then, when the lid 15 is rotated in the tightening direction, the inner cylinder 3 further enters the outer cylinder 2 while rotating, and the portion above the outer diameter small diameter portion 11 of the inner cylinder 3 is the outer cylinder 2. When the small-diameter portion 6 is reached by overcoming the annular projecting edge 7 and reaching the small-diameter portion 6, the powder a in the sealed container 1 is cut off from the outside and is in a sealed state (see FIG. 3).

この密閉状態において、外筒２の係止つば部９に内筒３の規制環１７が係止された状態となり、前記内筒３の前記外筒２に対するさらなる進入は阻止される（図４、図５参照）。この状態で、粉末ａを収容した密閉容器１は保管され、商品として供給される。なお、粉末ａを、図１状態とは上下反転した内筒３内に収容し、外筒２をこの内筒３に被せるようにして、その雄ねじ部８を蓋体１５の雌ねじ部１４に螺合し、密閉状態にしてもよい。   In this sealed state, the restriction ring 17 of the inner cylinder 3 is locked to the locking collar portion 9 of the outer cylinder 2, and further entry of the inner cylinder 3 into the outer cylinder 2 is prevented (FIG. 4, (See FIG. 5). In this state, the sealed container 1 containing the powder a is stored and supplied as a product. The powder a is accommodated in the inner cylinder 3 that is inverted upside down from the state shown in FIG. 1, and the outer cylinder 2 is covered with the inner cylinder 3, and the male screw portion 8 is screwed onto the female screw portion 14 of the lid 15. May be sealed.

この密閉状態にある密閉容器１を、ミネラルウォターを収容したボトル４１の本来のキャップ（図示せず）を外したうえ、その首部４２の雄ねじ部４３に、外筒２の雌ねじ部１０を螺合して、ボトル４１に装着する（図４，図５参照）。この状態で、蓋体１５を締め付け方向にさらに回転すると、ブリッジ１６が切断して規制環１７が切り離される。この切り離した規制環１７は、除去してもよいし、図示のように、そのまま放置しておいてもよい。蓋体１５の締め付け方向への回転を続行すると、内筒３は回転しながらさらに外筒２内に進入し、その押圧部１２の先端で底蓋５の肉薄部４を部分的に押圧して破断し、先端は破断した肉薄部分をさらに押圧する（図６参照）。   After the cap (not shown) of the bottle 41 containing the mineral water is removed from the sealed container 1 in the sealed state, the female screw portion 10 of the outer cylinder 2 is screwed into the male screw portion 43 of the neck portion 42. And it mounts | wears with the bottle 41 (refer FIG. 4, FIG. 5). In this state, when the lid 15 is further rotated in the tightening direction, the bridge 16 is cut and the regulating ring 17 is cut off. The separated regulation ring 17 may be removed, or may be left as it is as illustrated. When the rotation of the lid 15 in the tightening direction is continued, the inner cylinder 3 further enters the outer cylinder 2 while rotating, and the thin portion 4 of the bottom lid 5 is partially pressed by the tip of the pressing portion 12. It breaks, and the tip further presses the broken thin part (see FIG. 6).

このようにして、蓋体１５の締め付け方向への回転にともなって、押圧部１２の先端から後端に向けて順次肉薄部４に当接する部分が、肉薄部４を押圧して徐々に破断部分を拡大していき、前記押圧部１２は先端からほぼ対称的に傾斜に沿って、底蓋５を押し開いていく。そして、破断部分が一定以上になると、底蓋５は前記押圧部１２により、図６上、下方に完全に押し開けられて、開放状態となる。この時、前記押圧部１２の切り欠き１３を設けた後端に対応して、押圧力が付与されていなかった肉薄部４の部分は、破断されずに残る（図７参照）。   Thus, as the lid body 15 rotates in the tightening direction, the portion that sequentially contacts the thin portion 4 from the front end to the rear end of the pressing portion 12 presses the thin portion 4 and gradually breaks. The pressing portion 12 pushes the bottom lid 5 along the inclination almost symmetrically from the tip. And when a fracture | rupture part becomes more than fixed, the bottom cover 5 will be completely opened downward by the said press part 12 on FIG. 6, and will be in an open state. At this time, the portion of the thin portion 4 to which no pressing force is applied remains without being broken, corresponding to the rear end of the pressing portion 12 where the notch 13 is provided (see FIG. 7).

そして、図７に示すように、底蓋５が開放されると、密閉容器１内に収容していた粉体ａは落下してミネラルウォターに溶解し、コーヒー飲料となる。このコーヒー飲料は、ボトル４１首部４２の雄ねじ部４３と外筒２の雌ねじ部１０との螺合をとくことにより、密閉容器１を外して、通常のボトル飲料と同様に飲むことができる。   Then, as shown in FIG. 7, when the bottom lid 5 is opened, the powder a stored in the sealed container 1 falls and dissolves in mineral water to become a coffee beverage. This coffee beverage can be taken in the same manner as a normal bottle beverage by removing the sealed container 1 by screwing the male screw portion 43 of the neck portion 42 of the bottle 41 and the female screw portion 10 of the outer cylinder 2.

なお、通常、押圧部１２の切り欠き１３を設けた部分の後端が肉薄部４に当接する前に、底蓋５は開放状態となるので、必ずしも切り欠き１３が存在しなくても、肉薄部４の全部が破断されることはほとんどないが、肉薄部４の一部を確実に残した状態で底蓋５を開放するためには、切り欠き１３が存在することが望ましい。また、上述の密閉容器１は、あらかじめ本来のキャップに換えて、ボトル４１に装着した状態で商品として供給することもできる。さらに、飲料用の粉末ａは、コーヒーに限らず、茶、ジュース等でもよい。   In general, the bottom cover 5 is opened before the rear end of the portion where the notch 13 of the pressing portion 12 is provided comes into contact with the thin portion 4. Therefore, even if the notch 13 is not necessarily present, the thin portion 5 is thin. Although the entire portion 4 is hardly broken, it is desirable that the notch 13 is present in order to open the bottom cover 5 in a state where a part of the thin portion 4 is reliably left. Further, the above-described sealed container 1 can be supplied as a product in a state where it is attached to the bottle 41 in advance instead of the original cap. Furthermore, the powder a for beverages is not limited to coffee, but may be tea, juice or the like.

またさらに、本発明は、上述したボトル飲料用の粉体ａを収容するほか、２液混合用の一方の液体を収容するものでもよく、この場合には、もう一方の液体を収容したボトルに装着する。さらにまた、密閉状態での収容が必要な各種検体や、試料の収容容器に適用することもできる。この収容容器のように、単に密閉容器としての機能だけでよい場合には、外筒２の雌ねじ部１０は設ける必要がないものである。さらに加えて、内径小径部は、環状突部７で構成するほか、小径部６のような段差部で構成してもよい。   Furthermore, the present invention may contain one liquid for mixing two liquids in addition to containing the above-mentioned bottle beverage powder a, and in this case, the bottle containing the other liquid Installing. Furthermore, the present invention can also be applied to various specimens that need to be stored in a sealed state, and sample storage containers. In the case where the function as a sealed container is sufficient as in this container, the female screw portion 10 of the outer cylinder 2 does not need to be provided. In addition, the inner diameter small diameter portion may be formed of a stepped portion like the small diameter portion 6 in addition to the annular protrusion 7.

また、内筒３の規制環１７の内周面下端に環状突部を設ける一方、外筒２の係止つば部９近傍の外周面に、密閉状態において前記環状突部が係合する凹入部を設け、蓋体１５を締め付け方向のみならず、締め付け方向と反対の開放方向に回転した場合にも、ブリッジ１６が破断して前記規制環１７が切り離されるよう構成すると、底蓋５の開放の有無にかかわらず、密閉状態が解除されたことを視覚により容易に確認することができる。   In addition, an annular protrusion is provided at the lower end of the inner peripheral surface of the restriction ring 17 of the inner cylinder 3, while a concave portion is engaged with the outer peripheral surface of the outer cylinder 2 in the vicinity of the locking collar 9 in a sealed state.
