Description

【0001】
【発明の属する技術分野】
この発明は、飲み物を収容する飲料容器と飲料容器用アダプタに関する。
【0002】
【従来の技術】
【特許文献1】特表2002−515384号公報
従来、飲料容器であるペットボトルは、注出口に直接口をつけて内容物である飲料を飲む場合が多い。また、飲みやすさ等の観点から注出口にストローを差して飲むこともあり、ペットボトル用のストローは、ペットボトルにストローを取り付けたり、ペットボトル内にストローを収容し使用するときに一端部を突出させるものなど、様々なストローが開発されている。
【0003】
ペットボトル内に蛇腹式のストローを収容し、キャップを外してストローを引出可能としたものとして、特許文献1に開示されている飲料容器用ストローが提案されている。これは、飲料容器の首部内にストローが挿通されたストッパを挿入し、飲用に際してストローの蛇腹管を引き延ばして使用可能としたものである。
【0004】
【発明が解決しようとする課題】
しかしながら、特許文献1の場合、蛇腹状のストローを引き出して飲む際にストローの吸い口部に手が触れ雑菌等が付着し、衛生上好ましくない上、ストローを収納する際も蛇腹部分の収縮が難しくきれいに収納できないものであった。さらに、特許文献1のストッパはその容器専用のものであり、その容器のネック部の内径に合わせた外径のストッパを設けなければならず、汎用性のないものであった。また、このストッパをネック内に挿入する際にストッパの底面がネックの開口縁に当たってスムーズに挿入できない場合が発生しやすく、製造上の歩留まりが悪くなるものであり、製造コスト及び製品コストが上昇してしまうものであった。さらに、ネック部内に設けられた蛇腹部分は引き延ばしに力を要し、何度も飲用と収納を繰り返すうちに、ストローの端部が潰れてしまい、飲みにくいものとなってしまうものであった。
【0005】
この発明は上記従来の技術の問題点に鑑みてなされたものであり、簡単な構造で安価に提供することができ、飲料容器から飲料がこぼれにくく、容易にストローにより飲料を飲むこともできる飲料容器と飲料容器用アダプタを提供することを目的とする。
【0006】
【課題を解決するための手段】
この発明は、一端部に筒状の注出口が形成された容器本体と、上記注出口に取り付けられた内蓋とを備え、上記内蓋は、外側面が上記注出口に圧接し注出口基端部に向かって径が僅かに小さくなるテーパ状に形成された取付部と、この取付部の小径部からさらに上記容器本体の底面に向かって径が小さくなるようにテーパ状に形成され上記容器本体内で上記内蓋の一端部を閉鎖するように形成された閉鎖部と、上記閉鎖部を貫通して設けられストローが挿通可能な透孔とを備えた飲料容器である。
【0007】
上記容器本体には、上記内蓋に挿通されるストローを備える。上記容器本体はペットボトルであり、上記容器本体の注出口は、容器本体底部に向かうに従い僅かに内径が小さくなったテーパ状に形成され、上記取付部のテーパ状の外側面がこの注出口のテーパ状内周面に圧入されて圧接している。上記透孔はストローを保持可能な径に形成され、上記閉鎖部には空気穴が形成されている。
【0008】
またこの発明は、一端部に筒状の注出口が形成された容器本体の注出口に取り付けられる内蓋であって、上記内蓋は、外側面が上記注出口に圧接し注出口基端部に向かって径が僅かに小さくなるテーパ状に形成された取付部と、この取付部の小径部からさらに上記容器本体の底面に向かって径が小さくなるようにテーパ状に形成され上記容器本体内で上記内蓋の一端部を閉鎖するように形成された閉鎖部と、上記閉鎖部を貫通して設けられストローが挿通可能な透孔とを備えた飲料容器用アダプタである。
【0009】
またこの発明は、一端部に筒状の注出口が形成された容器本体の注出口に取り付けられる内蓋であって、上記内蓋は、外側面が上記注出口に圧接し注出口基端部に向かって径が僅かに小さくなるテーパ状に形成された取付部と、この取付部の小径部からさらに上記容器本体の底面に向かって径が小さくなるようにテーパ状に形成され上記容器本体内で上記内蓋の一端部を閉鎖するように形成された閉鎖部と、上記閉鎖部を貫通して設けられストローが挿通可能な透孔とを備え、上記閉鎖部には空気穴が形成され、上記透孔には上記容器本体底面に達するストローを取り付け可能に設けられ、このストローは上記内蓋の上記透孔に保持される大径管とこの大径管に挿通され進退自在に設けられた小径管とから成り、上記大径管は上記透孔から上記容器本体の底部の角に到達可能に設けられ、上記小径管は上記内蓋の内側に位置して伸縮自在に設けられている飲料容器用アダプタである。
【0010】
上記閉鎖部は、上記透孔に向かうに従い外径が小さくなる割合が、上記取付部よりも大きいテーパ状に形成され、上記閉鎖部の端部の径がほぼ上記ストローを挿通可能な径に形成されている。さらに、上記ストローの上記容器本体の底面側端部の周縁部には、切欠部が形成されているとよい。空気穴は、容器本体を立てた状態で、内蓋内に浸入している飲料が容器本体内に自然落下するように、ある程度の大きさにまたは複数個あけられていると良い。
【0011】
【発明の実施の形態】
以下、この発明の実施形態について図面に基づいて説明する。図1〜図4はこの発明の一実施形態を示すものであり、この実施形態の飲料容器10は、例えばPET(ポリエチレンテレフタレート)樹脂製のペットボトルであり、略有底筒状の容器本体12を有し、容器本体12の先端部には筒状の注出口14が一体に形成されている。注出口14の外側面には雄ねじ16が形成されている。注出口14には、キャップ18が、着脱自在に設けられている。キャップ18の内周面には、雌ねじ20が形成され、注出口14の雄ねじ16に螺合されている。
【0012】
注出口14の内周面は、容器本体12の底面12aに向かうに従い僅かに内径が小さくなったテーパ状に形成されている。これは、ペットボトルをブロー成形する際に注出口14に入れた型の抜きテーパである。注出口14の内側には、飲料容器用アダプタ11のPET樹脂製の内蓋22が圧入により固定されている。内蓋22は、注出口14のテーパ状の内周面に嵌合するように、外側面が注出口14の基端部14bに向かって径が小さくなるテーパ状に形成された取付部24が設けられている。内蓋22の取付部24は、注出口14の先端部14a側の端部と一致するか僅かに下方に嵌り込んで、注出口14の内周面に密に圧接している。取付部24の、注出口14の基端部14b側の端部には、取付部24の小径部24aからさらに容器本体12の底面12aに向かって径が小さくなるようにテーパ状に形成され、容器本体12内で内蓋22の下端部を閉鎖する閉鎖部26が設けられている。閉鎖部26は、下端部に向かうに従い外径が小さくなる割合が、取付部24よりも大きいテーパ状に形成されている。
【0013】
閉鎖部26のほぼ中央は、後述するストロー30の大径管30aの外径よりも僅かに大きな内径の透孔28が形成され、ストロー30が挿通される。透孔28は、注出口14の基端部よりも容器本体12の底面12a側に位置している。透孔28の内径は、閉鎖部26の先端の小径部26aとほぼ等しいか僅かに小さい内径に形成されている。また、閉鎖部26の、透孔28の近傍には、小さい空気穴31が形成されている。この空気穴31は、容器本体12を立てた状態で、内蓋22内に浸入している飲料が容器本体12内に自然落下する程度の大きさに、一個または複数個あけられていると良い。
【0014】
内蓋22の透孔28は、ストロー30が挿通可能に形成されている。ストロー30は、内蓋22の透孔28に保持される大径管30aとこの大径管30aに挿通され進退自在に設けられた小径管30bとから成る。大径管30aは28透孔から容器本体12の底部12aの角に到達可能に設けられ、小径管30bは内蓋22の内側に位置して大径管30a内を伸縮自在に設けられている。ストロー30の、容器本体12の底面12a側の周縁部には、U字形等の切欠部32が数カ所に形成されている。
【0015】
ストロー30の大径管30aは、透孔28に嵌合され引き抜き方向にはストロー30が簡単には抜けないように取り付けられていると良い。これにより小径管30bの引き出しが容易となる。また、大径管30aが透孔28よりも小さい場合、空気穴31が不要となり、内蓋22の製造コストを抑えることができる。
【0016】
次に、この実施形態の飲料容器10の使用方法について説明する。飲料容器10には、内蓋22が予め装着され、飲料が収容されている。また、容器本体12の外側に別体に又は内部にストロー30が設けられていても良い。予め容器本体12内に飲料とともにストロー30が設けられている場合は、図3に示すようにストロー30の小径管30bを縮めて内蓋22内に収容した状態にする。
【0017】
飲料容器10から飲料を飲むときは、キャップ18を外してストロー30を内蓋22の透孔28から差し込む。そして、図4に示すように、ストロー30の小径管30bを伸ばして飲用する。このときストロー30の大径管30aが内蓋22の透孔28に保持固定されていると、片手で容器本体12を保持し他方の手で簡単にストロー30の小径管30bを引き出すことができる。そしてストロー30に口をつけて飲料を飲む。ストロー30の先端に切欠部32が設けられている場合、飲料が入りやすく吸い込みやすい。
【0018】
この実施形態の飲料容器10及び飲料容器用アダプタ11によれば、簡単な構造でストロー30で容器本体12から飲料を飲むことができる。飲料容器用アダプタ11は、取付部24がテーパ状に形成され、容器本体12の注出口14内に嵌合する場合も、注出口14の内径に多少のバラツキがあっても、テーパにより確実に密着させ固定することができ、内蓋22と注出口14との隙間から飲料が漏れることがない。また、容器本体12の注出口14への取り付け工程においても、閉鎖部26のテーパにより、容易に迅速に挿入することができ、自動化も簡単に可能である。さらに、取付部24のテーパにより、ペットボトル等の容器本体12の種類による内径の多少の差があっても、取付部24を注出口14に圧縮状態で圧入し、取付部24は多少圧縮変形して取り付けられる。これにより、1種類または少ない種類の内蓋22で多種類の容器本体12に対応することができ、内蓋22の汎用性が高く、コストも極めて低いものとすることができる。また、取付用の自動機も共用可能であり、製造コストを大幅に抑えることができる。
【0019】
さらに、透孔28はテーパ状の閉鎖部26の小径部26aとほぼ等しいか僅かに小さい内径に形成され、ストロー30を挿入する際も、ストローが閉鎖部26の内面に案内されて容易に透孔28に差し込まれる。また、内蓋22は注出口14に密着され、透孔28はストロー30が挿入される程度の小さい孔であり、誤って容器本体12を倒しても、飲料が大量に流れ出ることはなく、安全である。ストロー30は、使用していないときは内蓋22の内側に収容され、キャップ18で覆われるため、ごみが付着することがなく衛生的である。さらに、内蓋22は、容器本体12の上方であって注出口14の基端部付近またはその下方に位置しているので、飲料の液面から内蓋22までの空気量が少なく、飲料が接する空気が少ないので飲料の酸化も抑えることができる。また、開栓後に外気や口に触れて容器本体内に戻る飲料の量が少なくなるため、開栓後の雑菌の繁殖を抑える。
【0020】
なお、この発明の飲料容器と飲料容器用アダプタは、上記実施形態に限定されるものではなく、内蓋の形状やストローの長さ構造等は、適宜変更可能である。例えばストローは、内蓋内に位置した部分を蛇腹状に形成して、伸縮可能としても良く、ストロー30の小径管30aの先端部には、ストロー30を引くときの手がかりとなる鍔部が形成されていても良い。内蓋は、ペットボトルの容器本体以外にも、アルミボトルやビン等、取付部の形状を変えることによりいろいろな飲料容器に取り付けることができる。注出口の取付部のテーパは、直線状のものの他、若干のうねりが形成されたものでも良く、これにより内蓋との嵌合がより強固になる。
【0021】
【発明の効果】
この発明の飲料容器と飲料容器用アダプタは、容器を誤って倒しても容器本体内の飲料がこぼれにくいものである。さらに、簡単にストローで飲料を飲むことができ、取り付けも容易である。また、この飲料容器用アダプタを取り付けた飲料容器の製造も容易で、テーパ状の取付部により、容器本体の注出口の多少のバラツキにも対応することができ、コストも極めて安価に製造可能である。また、ストローは簡単に引き出したり収容したりすることができ、使用しないときはキャップに覆われているため、衛生的である。

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 4 show an embodiment of the present invention. A beverage container 10 of this embodiment is, for example, a PET (polyethylene terephthalate) resin PET bottle, and has a substantially bottomed cylindrical container body 12. And a cylindrical spout 14 is integrally formed at the tip of the container body 12. A male screw 16 is formed on the outer surface of the spout 14. A cap 18 is provided at the spout 14 so as to be detachable. A female screw 20 is formed on the inner peripheral surface of the cap 18 and is screwed to the male screw 16 of the spout 14.
[0012]
The inner peripheral surface of the spout 14 is formed in a tapered shape in which the inner diameter becomes slightly smaller toward the bottom surface 12 a of the container body 12. This is a removal taper of a mold inserted into the spout 14 when the PET bottle is blow-molded. Inside the spout 14, an inner lid 22 made of PET resin of the beverage container adapter 11 is fixed by press-fitting. The inner lid 22 includes a tapered mounting portion 24 whose outer surface is tapered so that its diameter decreases toward the base end portion 14 b of the spout 14 so as to fit into the tapered inner peripheral surface of the spout 14. Is provided. The mounting portion 24 of the inner lid 22 coincides with or slightly fits down with the end of the spout 14 on the side of the tip portion 14 a, and closely contacts the inner peripheral surface of the spout 14. At the end of the mounting portion 24 on the base end portion 14b side of the spout 14, the tapered shape is formed so that the diameter decreases from the small diameter portion 24a of the mounting portion 24 toward the bottom surface 12a of the container body 12. A closing portion 26 for closing the lower end of the inner lid 22 in the container body 12 is provided. The closing portion 26 is formed in a tapered shape in which the outer diameter decreases toward the lower end portion more than the mounting portion 24.
[0013]
A through hole 28 having an inner diameter slightly larger than the outer diameter of a large-diameter tube 30a of the straw 30 described later is formed at substantially the center of the closing portion 26, and the straw 30 is inserted therethrough. The through hole 28 is located closer to the bottom surface 12 a of the container body 12 than the base end of the spout 14. The inner diameter of the through hole 28 is formed to be substantially equal to or slightly smaller than the small diameter portion 26 a at the tip of the closing portion 26. Further, a small air hole 31 is formed in the vicinity of the through hole 28 in the closing portion 26. One or a plurality of the air holes 31 may be formed in such a size that the beverage penetrating into the inner lid 22 naturally falls into the container main body 12 with the container main body 12 standing. .
[0014]
The through hole 28 of the inner lid 22 is formed so that a straw 30 can be inserted therethrough. The straw 30 includes a large-diameter pipe 30a held in the through hole 28 of the inner lid 22, and a small-diameter pipe 30b inserted through the large-diameter pipe 30a and provided to be able to move forward and backward. The large-diameter tube 30a is provided so as to be able to reach the corner of the bottom 12a of the container main body 12 from the 28 through-hole, and the small-diameter tube 30b is located inside the inner lid 22 and is provided to extend and contract inside the large-diameter tube 30a. . At the periphery of the straw 30 on the side of the bottom surface 12a of the container body 12, cutouts 32 such as U-shaped are formed at several places.
[0015]
The large-diameter pipe 30a of the straw 30 is preferably fitted to the through hole 28 so that the straw 30 is not easily pulled out in the pulling-out direction. This facilitates pulling out the small diameter tube 30b. When the large diameter pipe 30a is smaller than the through hole 28, the air hole 31 becomes unnecessary, and the manufacturing cost of the inner lid 22 can be reduced.
[0016]
Next, a method of using the beverage container 10 of this embodiment will be described. The beverage container 10 is provided with an inner lid 22 in advance, and accommodates a beverage. Further, a straw 30 may be provided separately or inside the container body 12. If the straw 30 is provided in the container body 12 together with the beverage in advance, the small-diameter tube 30b of the straw 30 is contracted to be housed in the inner lid 22 as shown in FIG.
[0017]
When drinking a beverage from the beverage container 10, the cap 18 is removed and the straw 30 is inserted through the through hole 28 of the inner lid 22. Then, as shown in FIG. 4, the small-diameter tube 30b of the straw 30 is extended to drink. At this time, if the large-diameter pipe 30a of the straw 30 is held and fixed in the through hole 28 of the inner lid 22, the container main body 12 can be held with one hand and the small-diameter pipe 30b of the straw 30 can be easily pulled out with the other hand. . Then, the user puts his mouth on the straw 30 to drink the beverage. When the notch 32 is provided at the tip of the straw 30, the beverage is easy to enter and suck.
[0018]
According to the beverage container 10 and the beverage container adapter 11 of this embodiment, it is possible to drink the beverage from the container body 12 with the straw 30 with a simple structure. The beverage container adapter 11 has a taper-shaped attachment portion 24, and can be reliably formed by the taper even when the fitting portion 24 is fitted into the spout 14 of the container main body 12 or the inner diameter of the spout 14 has some variation. The beverage can be adhered and fixed, and the beverage does not leak from the gap between the inner lid 22 and the spout 14. Also, in the process of attaching the container body 12 to the spout 14, the taper of the closing portion 26 allows easy and quick insertion and easy automation. Furthermore, even if there is a slight difference in the inner diameter depending on the type of the container body 12 such as a plastic bottle due to the taper of the mounting portion 24, the mounting portion 24 is pressed into the spout 14 in a compressed state, and the mounting portion 24 is slightly compressed and deformed. Attach it. Thus, one or a small number of types of inner lids 22 can be used for various types of container main bodies 12, and the versatility of the inner lids 22 is high, and the cost can be extremely low. In addition, the automatic machine for mounting can be shared, and the manufacturing cost can be greatly reduced.
[0019]
Further, the through hole 28 is formed to have an inner diameter substantially equal to or slightly smaller than the small diameter portion 26a of the tapered closing portion 26, so that even when the straw 30 is inserted, the straw is guided to the inner surface of the closing portion 26 and is easily transparent. It is inserted into the hole 28. Further, the inner lid 22 is in close contact with the spout 14, and the through-hole 28 is a small hole into which the straw 30 is inserted. It is. When the straw 30 is not in use, it is housed inside the inner lid 22 and covered with the cap 18, so that the straw 30 does not adhere to dust and is sanitary. Furthermore, since the inner lid 22 is located above the container body 12 and near or below the base end of the spout 14, the amount of air from the liquid level of the beverage to the inner lid 22 is small, and Oxidation of the beverage can be suppressed because there is little air in contact.
