Description

【０００１】
【発明の属する技術分野】
本発明は、携帯用の金属製保温容器に関する。
【０００２】
【従来の技術】
マラソンやサッカー等の運動時に短時間で吸水を行うために、容器に直接ストローや吸い口を設け、容器から直接飲むことができる携帯用の容器がある。この容器は合成樹脂製のものが多く、一重の容器であるために、容器を握ると内容物の温度を感じることができる。
【０００３】
【発明が解決しようとする課題】
しかし、上述の容器では保温性に乏しく、内容物の温度を維持することが困難である。一方、保温容器は、内容物の温度を長時間に亘って維持できるが、内筒と外筒との間に断熱部を有するため、保温容器の外側からは内容物の温度を知ることができない。
【０００４】
そこで本発明は、外側から内容物の温度を感知することができる金属製保温容器を提供することを目的としている。
【０００５】
【課題を解決するための手段】
上記した目的を達成するため、本発明は、内筒と外筒との間に断熱部を有する金属製容器本体と、該容器本体の開口部に着脱可能に装着した蓋部材とを備えた金属製保温容器において、前記内筒又は外筒のいずれか一方又は双方の側壁に、他方の側壁に接触する凸部を形成し、前記凸部により前記内筒と外筒の一部同士が接触する熱感知部を設け、前記熱感知部によって前記容器本体内の内容物の温度が感知できることを特徴としている。また、前記熱感知部を複数個設けていてもよく、前記熱感知部に、温度によって色が変化するシールを貼着してもよい。
【０００６】
【発明の実施の形態】
以下、本発明の各実施形態例を図面に基づいてさらに詳細に説明する。なお、各実施形態例において同一又は同様の部分には、第１実施形態例と同じ符号を用いてその説明を省略する。
【０００７】
図１及び図２は本発明の第１実施形態例を示すもので、金属製保温容器１は、断熱構造の金属製容器本体２と、該容器本体２の開口部に着脱可能に装着したコップ兼用の蓋部材３とを備えている。金属製容器本体２は、金属製の有底内筒４及び金属製の有底外筒５の上端開口部同士を一体に接合したもので、両筒４，５間には真空断熱構造の断熱部６を形成している。また、外筒５の底部に底部材７を取り付けている。
【０００８】
外筒５は、側壁の一部に、内筒４の側壁に接触する凸部５ａを同高位置に１８０度対向して２個形成している。これにより、外筒５の表面には、内筒４と外筒５の一部同士が接触する熱感知部８が２ケ所設けられたことになり、該熱感知部８に触ることによって、金属製保温容器１内の内容物の温度を感知することができる。また、外筒５に形成した凸部５ａにより外筒５の表面に凹部が形成されるから、該凹部によって金属製保温容器１の胴部を握りやすくまた携帯時に保持しやすい。
【０００９】
前記蓋部材３は、天板３ａに止水可能な吸い口１１を突設するとともに減圧解除弁１２を設けている。吸い口１１は、天板３ａの一側から立ち上がる、流路１３ａを有する円筒状の吸い口本体部１３と、該吸い口本体部１３に沿って軸線方向に移動可能に外嵌されて前記流路１３ａを開閉する吸い口部１４と、該吸い口部１４に着脱可能に被着される吸い口キャップ１５とで構成されている。
【００１０】
吸い口本体部１３は、先端中央に円柱状のガイド１３ｂと、該ガイド１３ｂの周囲に形成した前記流路１３ａと、先端外周に突出形成した前記吸い口部１４の抜け止めストッパ１３ｃとを有している。吸い口部１４は、筒体１４ａの天面１４ｂの中央に形成した前記ガイド１３ｂが挿入される貫通孔１４ｃと、筒体１４ａの中間部内周に形成した前記抜け止めストッパ１３ｃに係合する突状部１４ｄと、筒体１４ａの上部外周に形成した吸い口キャップ１５の係止部１４ｅとを有している。吸い口キャップ１５は、吸い口部１４に被着されるキャップ部１５ａと、吸い口本体部１３の基部に取り付けられる保持リング１５ｂと、キャップ部１５ａと保持リング１５ｂとを繋いでＵ字状に屈曲される保持帯１５ｃとを有している。キャップ部１５ａは、上部内周に形成した前記吸い口部１４の係止部１４ｅに係合する係止部１５ｄと、上部外周に形成したキャップ部１５ａを開ける手掛かりとなる突起１５ｅとを有している。
【００１１】
また、蓋部材３の天板３ａの他側には、容器本体２内の減圧を防止するための空気孔１６がスリット状に形成され、該空気孔１６に前記減圧解除弁１２が設けられている。減圧解除弁１２は、空気孔１６に挿通される弁軸１２ａと、該弁軸１２ａの下部に設けられた弁体１２ｂと、弁軸１２ａの上部に形成された抜け止め部１２ｃとを有し、天板３ａの内面側に配置した弁体１６ｂは、容器本体２内が減圧されると撓んで空気孔１６を開き、容器本体２内が正圧に戻った場合及び容器本体２内の飲料水の圧力が作用した場合は空気孔１６を閉じる。
【００１２】
このように構成された金属製保温容器１は、図１に示されるように、吸い口１１の吸い口部１４に吸い口キャップ１５が被着された状態では、貫通孔１２ｃと流路１１ａとが閉じ、空気孔１６も弁体１２ｂにより閉じている。
【００１３】
そして、金属製保温容器１の胴部を掴んで、手又は口で突起１５ｅを引き上げると、吸い口部１４が吸い口キャップ１５と共に引上げられ、吸い口部１４は、突状部１４ｄが抜け止めストッパ１３ｃに係合するまで移動し、係止部１５ｄが係止部１４ｅを乗り越えると、吸い口キャップ１５が吸い口部１４から外れ、これにより、貫通孔１４ｃ及び流路１３ａが開く。このとき、熱感知部８に接触すると内容物の温度を感知できる。
【００１４】
この状態で、吸い口部１４に口を付け、吸い口１１が下側になるように保温容器１を傾けて飲料水を吸うと金属製保温容器１内が減圧され、減圧解除弁１２の弁体１２ｂが撓んで空気孔１６を開き、空気孔１６から外気が導入され、保温容器１内が負圧にならず、保温容器１内の飲料水を流路１３ａを介して貫通孔１４ｃから飲むことができる。
【００１５】
図３は本発明の第２実施形態例を示すもので、本実施形態例は、断熱構造の金属製容器本体２の開口部にコップ兼用の蓋部材３を着脱可能に設けた金属製保温容器１である。この金属製保温容器１は、内筒４の側壁の一部に、外筒５の側壁に接触する凸部４ａが同高位置に等間隔に４個形成され、これにより、外筒５の表面に熱感知部８が４ケ所設けられる。この熱感知部８は、外筒５の表面に色を塗っておくとその位置が解りやすい。
【００１６】
図４は本発明の第３実施形態例を示すもので、本実施形態例の熱感知部８は、第２実施形態例と同様に構成されおり、外筒５表面の熱感知部８に相当する部分に、温度によって色が変化するシール９を貼着したものである。これにより、熱感知部８に触れることなく、金属製保温容器１内の内容物の温度を感知することができる。
【００１７】
上記各実施形態例の熱感知部８によって金属製保温容器１内の内容物の温度を感知することができる。また、内筒４及び／又は外筒５に複数の凸部４ａ，５ａを形成することにより、内筒４と外筒５とを組付ける工程において、内筒４と外筒５とに芯ずれが生じず、上端開口部同士の接合が容易にでき、製造コストの低減が可能である。なお、内筒４と外筒５との芯だしを行うためには、凸部４ａ，５ａを３個以上等間隔に形成することが望ましい。また、内筒４に凸部４ａを、外筒５に凸部５ａをそれぞれ形成して、両凸部４ａ，５ａを接触させてもよい。さらに、熱感知部８は、金属製保温容器１内の内容物が少なくなった時でも温度を知ることができるように、複数の熱感知部８の位置を同一高さでなく、その中の少なくとも一つあるいは別実施形態例の熱感知部を容器本体２の底部付近に配置することが望ましい。また、上記各実施形態例では、容器本体２を真空断熱構造のもので説明したが、断熱構造はこれに限らず、低熱伝導率ガスを封入した断熱構造、発泡ウレタン等の断熱材を用いた断熱構造等であってもよい。
【００１８】
【発明の効果】
以上のように、本発明の金属製保温容器は、容器本体の内筒又は外筒のいずれか一方又は双方の側壁に、他方の側壁に接触する凸部を形成し、前記内筒及び外筒の一部同士が接触する熱感知部を設けたので、熱感知部によって金属製保温容器内の内容物の温度を感知することができる。また、熱感知部を複数個設けることにより、内筒又は外筒の側壁に複数の凸部が形成されるから、内筒と外筒とを組付ける工程において、内筒と外筒とに芯ずれが生じず、内筒と外筒の上端開口部同士の接合が容易にでき、製造コストの低減が可能である。さらに、熱感知部に、温度によって色が変化するシールを貼着することにより、熱感知部に触れなくても金属製保温容器内の内容物の温度を知ることができる。
