Description

この考案は、粉末状の原料を収容する原料収容部を有し、開栓操作に伴い原料収容部の内筒底蓋を脱落させて原料をボトル内に放出するボトルキャップに関する。   The present invention relates to a bottle cap that has a raw material storage part that stores a powdery raw material, and releases the raw material into the bottle by dropping off the inner cylinder bottom cover of the raw material storage part in accordance with the opening operation.

従来、この種のボトルキャップとして、例えば特開平８−９１４１８号の二剤混合容器（特許文献１）や、特開２００５−８８９９７号のボトルキャップ（特許文献２）などが知られている。   Conventionally, as this kind of bottle cap, for example, a two-component mixing container disclosed in JP-A-8-91418 (Patent Document 1) and a bottle cap disclosed in JP-A-2005-88997 (Patent Document 2) are known.

これらのボトルキャップを、緑茶のペットボトルに用いる場合には、内筒部内部に充填する茶葉の微粉末の変質を防止するため、遮光性を有する樹脂材で成型されるのが通常である。
しかし、たとえば、ペットボトルが透明である場合、射し込む光がペットボトルをレンズとして増強され、樹脂の遮光性だけでは不十分であり、茶葉の微粉末を酸化させるなど劣化させる危険があった。 When these bottle caps are used for green tea plastic bottles, they are usually molded with a light-shielding resin material in order to prevent alteration of the fine powder of tea leaves that fills the inner cylinder.
However, for example, when the PET bottle is transparent, the incident light is enhanced by using the PET bottle as a lens, and the light-shielding property of the resin is not sufficient, and there is a risk of deterioration such as oxidation of the fine powder of tea leaves.

また従来のボトルキャップでは、内筒部と外筒部の間の隙間にボトル内の液体が侵入しないように外筒部下端部と内筒底蓋外周縁にそれぞれ段差を設けるなどの構成を採用しているが、シール性の確保が困難であった。
特開平８−９１４１８号公報 特開２００５−８８９９７号公報 In addition, the conventional bottle cap adopts a configuration in which a step is provided on the lower end of the outer cylinder and the outer periphery of the inner cylinder bottom lid so that the liquid in the bottle does not enter the gap between the inner cylinder and the outer cylinder. However, it was difficult to ensure sealing performance.

At the same time, the sealing ring 23 is press-fitted into the spout portion 6a, the top portion 3a of the upper lid body 3 presses against the upper end of the spout portion 6a, and the sealing ring 23 is pressed against the spout portion 6a in the body portion 3b direction. Hold from.

内筒部４に内筒底蓋９を嵌着するときは、図４に示すように、内筒部４の下端の凹部６ｅに内筒底蓋９の周壁部９ｃの内向き段部９ｄが係合し、内筒底蓋９の環状溝部９ａに内筒部４の下端外縁を押しつけるように密着させ、内筒部４の下端との間で主シール部Ｓ１によって密着される。
これと同時に、前述のように、外筒部６の下端部が内筒底蓋９の周壁部９ｃの上端との間で補助シール部Ｓ２によって密着される。 When the inner cylinder bottom cover 9 is fitted to the inner cylinder part 4, as shown in FIG. 4, the inward stepped part 9d of the peripheral wall part 9c of the inner cylinder bottom cover 9 is formed in the recess 6e at the lower end of the inner cylinder part 4. Engage with each other so that the outer edge of the lower end of the inner cylinder part 4 is pressed against the annular groove 9a of the inner cylinder bottom cover 9 and is in close contact with the lower end of the inner cylinder part 4 by the main seal part S1.
At the same time, as described above, the lower end portion of the outer cylinder portion 6 is closely attached to the upper end of the peripheral wall portion 9c of the inner cylinder bottom lid 9 by the auxiliary seal portion S2.

これにより、内筒部４を密封することができるだけでなく、内筒底蓋９と外筒部６とが密着して内筒部４のシール性を更に向上させることができる。
この内筒部４内には、本実施例では茶葉の微粉末が収納される。
また、上記茶葉の微粉末と共に圧力気体を共に封入してもよい。 Thereby, not only can the inner cylinder part 4 be sealed, but the inner cylinder bottom cover 9 and the outer cylinder part 6 can be brought into close contact with each other to further improve the sealing performance of the inner cylinder part 4.
In this embodiment, fine powder of tea leaves is stored in the inner cylinder portion 4.
Further, a pressure gas may be enclosed together with the fine powder of tea leaves.

上記のようにして組み立てたボトルキャップを、ペットボトル等のボトル５０の口頸部５１に装着する場合、外筒部６をボトル口頸部５１内に挿入し、上蓋取付部５の嵌着本体部５Ａを閉じる方向に回して、嵌着本体部５Ａの雌ネジＮ２をボトル口頸部５１の雄ネジＮ１に螺合しし、抜け止め防止リング５ｂがボトルの口頸部５１の下部に形成した抜け止めリング５ｂを越え、口頸部５１の上端が環状突部５ｂに押しつけられた状態になる位置まで緊締し、ボトル５０とボトルキャップ１とを強固に密着させる。   When the bottle cap assembled as described above is attached to the mouth / neck portion 51 of the bottle 50 such as a plastic bottle, the outer cylinder portion 6 is inserted into the bottle mouth / neck portion 51 and the fitting body of the upper lid attaching portion 5 is inserted. The part 5A is turned in the closing direction, and the female thread N2 of the fitting main body part 5A is screwed into the male thread N1 of the bottle neck part 51, and a retaining ring 5b is formed below the mouth neck part 51 of the bottle. The bottle 50 and the bottle cap 1 are firmly brought into close contact with each other until the upper end of the mouth-and-neck portion 51 is pressed against the annular protrusion 5b beyond the retaining ring 5b.

このボトル５０を使用する場合は、上蓋２の上蓋本体３を上蓋取付部５に対し開く方向に回して螺進させると、上蓋２のバンド部１１は、上蓋取付部５側の抜け止め部６ｄにより上昇を阻止されるため、バンド部１１との連結部であるブリッジ１２が切断してバンド部１１と上蓋本体３とが分離して上下に変位し、更に凹部１３ａと凸部１３ｂとの嵌合も外れる。   When this bottle 50 is used, when the upper lid body 3 of the upper lid 2 is rotated in the opening direction with respect to the upper lid mounting portion 5 and screwed, the band portion 11 of the upper lid 2 is secured to the retaining portion 6d on the upper lid mounting portion 5 side. Therefore, the bridge 12 which is a connecting portion with the band portion 11 is cut, the band portion 11 and the upper lid body 3 are separated and displaced up and down, and the fitting between the concave portion 13a and the convex portion 13b is further performed. It will be off.

上蓋２を更に回転させると、これに伴いその内筒部４も回転しながら上昇するが、内筒底蓋９の周壁部９ｃの上端は外筒部６の下端に当接しているので上昇が阻止され、内筒部４から外れる。
これにより、内筒部４の下面が開放されて、収納されていた茶葉の微粉末が吐出され、内筒底蓋９は回転しながらボトル５０の液体内に渦を形成しながら沈下する。
上蓋２を抜き取っても、上蓋取付部５は、上記したように抜け止めリング５ｂの噛合によりボトル口頸部５１から外れない。 When the upper lid 2 is further rotated, the inner cylinder part 4 is also raised while rotating, but the upper end of the peripheral wall part 9c of the inner cylinder bottom lid 9 is in contact with the lower end of the outer cylinder part 6 so that the rise is increased. It is blocked and disengages from the inner cylinder part 4.
As a result, the lower surface of the inner cylinder portion 4 is opened, and the stored fine powder of tea leaves is discharged, and the inner cylinder bottom lid 9 sinks while forming a vortex in the liquid of the bottle 50 while rotating.
Even if the upper lid 2 is pulled out, the upper lid attaching portion 5 does not come off the bottle neck portion 51 due to the engagement of the retaining ring 5b as described above.

上蓋２を抜き取った後も、上蓋取付部５は、その外筒部６をボトル口頸部５１中に嵌合させたまま残る。
そのため、垂下筒部６ｂ外側とボトル口頸部５１の内側の間に液が入って排出しにくくならないよう、公知の手段であるスリットや孔を垂下筒部６ｂに設けてもよい。 Even after the upper lid 2 is removed, the upper lid attaching portion 5 remains with its outer cylinder portion 6 fitted in the bottle mouth / neck portion 51.
Therefore, a slit or a hole, which is a known means, may be provided in the hanging cylinder portion 6b so that the liquid does not easily enter and drain between the outside of the hanging cylinder portion 6b and the inside of the bottle neck portion 51.

また、上記実施例では、内筒部内に茶葉の微粉末を収納した場合を例示したが、この発明では、その他の飲料用の粉末や粒体などを収納するものであってもよい。
その他、用途に応じ、この考案の要旨を変更しない範囲内で種々設計することが可能である。 Moreover, in the said Example, although the case where the fine powder of the tea leaf was accommodated in the inner cylinder part was illustrated, in this invention, you may accommodate the powder, granule, etc. for other drinks.
In addition, various designs can be made within a range that does not change the gist of the invention according to the application.
