Description

飲料容器Beverage container
　本発明は、飲料容器に関する。さらに詳しくは、両端開口の本体とその両端に設けられた蓋体を有する飲料容器に関する。 The present invention relates to a beverage container. More specifically, the present invention relates to a beverage container having a main body with openings at both ends and lids provided at both ends.
　従来飲料容器として、耐久性、耐衝撃性、耐熱性などの特性がある容器が多く用いられている。その機能が携行可能型であったり、室内載置型であったりすることから、目的に応じて水筒、ポット、魔法瓶などという名称が付けられてきた。それらの外観形状、材質、内部機構等は使用目的に応じて工夫されてきた。 Conventionally, as beverage containers, containers having properties such as durability, impact resistance and heat resistance are often used. Since the function is portable or indoor-mounted, names such as water bottles, pots, and thermos bottles have been given depending on the purpose. Their external shape, material, internal mechanism, etc. have been devised according to the purpose of use.
　これらの飲料容器に求められる特性に、内容物の付着により生じる汚染を防ぐ防汚性、同汚染を除去する洗浄性がある。また、内容物の高温もしくは低温を保持する保温性が求められる用途もある。 The characteristics required for these beverage containers include antifouling properties that prevent contamination caused by the adhesion of contents, and detergency that removes the contamination. In addition, there is an application in which the heat retaining property for maintaining the high or low temperature of the contents is required.
　飲料用容器、特に金属製や耐熱性樹脂製飲料容器の内面の防汚性付与と、保温性向上のために、容器内周にフッ素樹脂等の樹脂をコーティングすることが行われている。
　飲料容器に、特に保温性を持たせる構造として、容器内部を二重構造として二重構造内を真空にした真空二重構造が知られている。以前はガラス製二重構造が主流であったが、割れ難さから最近は金属製二重構造が多く使用されている。
　防汚性と保温性を有する飲料容器として、金属製二重構造体の内面にフッ素樹脂をコーティングしたものも提案されている（特許文献１および２）。 In order to impart antifouling properties to the inner surface of a beverage container, particularly a metal or heat resistant resin beverage container, and to improve heat retention, a resin such as a fluororesin is coated on the inner periphery of the container.
2. Description of the Related Art A vacuum double structure in which a beverage container is provided with a heat retaining property and a vacuum is formed in the double structure is known as a double structure. In the past, glass double structures were the mainstream, but recently, metal double structures are often used because of their difficulty in breaking.
As a beverage container having antifouling properties and heat retaining properties, a metal double structure having an inner surface coated with a fluororesin has also been proposed (Patent Documents 1 and 2).
　しかしながら、従来公知のこれら飲料容器は、底部密閉構造で上部にのみ蓋を有する構造であるため、容器内面を洗浄し難く、特に細高い形状の容器では内面を綺麗に洗うのは難しく、衛生面の維持には困難を伴っていた。また、製造工程でフッ素樹脂をコーティングする際には、容器の側面、角部及び底面に塗装するので、膜厚にバラツキが出やすく、焼成温度も不均一となる結果、塗膜のクラック発生や粘着性が十分でないために期待する性能を発揮させるのが難しいという問題もあった。 However, these conventionally known beverage containers have a closed bottom structure and have a lid only at the top, so it is difficult to clean the inner surface of the container. It was difficult to maintain. In addition, when coating fluororesin in the manufacturing process, it is applied to the side, corners and bottom of the container, so the film thickness tends to vary and the firing temperature becomes uneven, resulting in the occurrence of cracks in the coating film. There is also a problem that it is difficult to exert the expected performance due to insufficient adhesiveness.

With the metal coating, it is possible to expect the effect of improving properties such as suppression of dirt adhesion to the inner surface, provision of corrosion resistance, and provision of durability. In addition, when an antibacterial metal such as silver or copper is coated, the antibacterial metal makes it difficult for bacteria and the like to propagate on the inner surface, which makes it even more hygienic.
Examples of the method for forming such a metal coating include various plating methods, vapor deposition, thermal spraying, and sputtering.
In the beverage container of the present invention, since sufficient openings are provided at both ends, the inner surface of the main body can be easily coated with metal in the manufacturing process.
　樹脂被膜の代表的な例としては、フッ素樹脂被膜を挙げることができる。フッ素樹脂被膜により、内面の防汚性と保温性を向上させることができる。また、樹脂被膜の性能を改善するため、公知の各種充填材を被膜中に加えることもできる。 A typical example of the resin film is a fluororesin film. By the fluororesin coating, the antifouling property and heat retention of the inner surface can be improved. Moreover, in order to improve the performance of the resin coating, various known fillers can be added to the coating.
　フッ素樹脂としては、ポリテトラフルオロエチレン（ＰＴＦＥ）やテトラフルオロエチレン－パーフルオロアルキルビニルエーテル共重合体（ＰＦＡ）、テトラフルオロエチレン－ヘキサフルオロプロピレン（ＦＥＰ）、ポリビニリデンフルオライド共重合体（ＰＶＤＦ）、ポリクロロトリフルオロエチレン共重合体（ＰＣＴＦＥ）、クロロトリフルオロエチレン－エチレン共重合体（ＥＣＴＦＥ）、テトラフルオロエチレン－エチレン共重合体（ＥＴＦＥ）など従来公知のものから選ぶことができる。 Examples of the fluororesin include polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), tetrafluoroethylene-hexafluoropropylene (FEP), polyvinylidene fluoride copolymer (PVDF), It can be selected from conventionally known ones such as polychlorotrifluoroethylene copolymer (PCTFE), chlorotrifluoroethylene-ethylene copolymer (ECTFE), and tetrafluoroethylene-ethylene copolymer (ETFE).
　フッ素樹脂被膜を形成させるために、飲料容器本体の内面にフッ素樹脂を塗装する方法としては、特に制限されるものではないが、フッ素樹脂の水性分散体をスプレー塗布したり、ディッピング、流延などの方法で容器本体の内面に塗布したりして乾燥させる方法、フッ素樹脂の微粉末を静電粉体塗装法、流動浸漬法などの方法で塗布する方法などを採用して塗布した後に、加熱条件下で焼成を行う方法を挙げることができる。塗布方法については、上記した方法に限定されるものではなく、従来公知の方法から適宜選択することができる。焼成の条件も特に制限されるものではないが、たとえば２００～４５０℃の温度で５～１８０分間焼成する条件が例示される。 In order to form the fluororesin coating, the method of coating the fluororesin on the inner surface of the beverage container main body is not particularly limited, but an aqueous dispersion of fluororesin is applied by spraying, dipping, casting, etc. After applying by applying the method of applying to the inner surface of the container body by the above method and drying, the method of applying fine powder of fluororesin by the electrostatic powder coating method, fluidized dipping method, etc., heating The method of baking under conditions can be mentioned.

　従来、フッ素樹脂をコーティングする際に、容器の側面、角部及び底面に塗装する場合、膜厚にバラツキが出やすく、焼成温度も不均一となり、塗膜のクラック発生や粘着性が十分でないという問題があったが、本発明の飲料容器では、底面及び角部が存在しないため、上記の問題は解消される。 When performing fluororesin coating, the inner surface of the container body may be roughened by a method such as blasting as a pretreatment. The adhesion of the coating can be improved by the roughening treatment.
The beverage container of the present invention is characterized in that the opening on both sides of the main body is provided with sufficient openings, so that the inner surface of the main body is easily subjected to fluororesin coating or roughening treatment.
Conventionally, when coating fluororesin on the sides, corners and bottom of the container, the film thickness tends to vary, the firing temperature becomes uneven, and cracks and adhesion of the coating are not sufficient. Although there existed a problem, in the drink container of this invention, since a bottom face and a corner | angular part do not exist, said problem is eliminated.
　また、フッ素樹脂塗装を行う際に、フッ素樹脂に金、銀、亜鉛、銅、チタンなどの金属微粉末を分散させることにより、抗菌性を有する樹脂被膜を形成させることもできる（特開２００８－２３９８８２号公報参照）。 In addition, when performing fluororesin coating, a resin film having antibacterial properties can be formed by dispersing fine metal powders such as gold, silver, zinc, copper, and titanium in the fluororesin (Japanese Patent Laid-Open No. 2008-2009). 239882).
　本発明の飲料容器の本体を二重構造として内部を真空にすると、保温性を高めることができるので、特に保温性を重要視する場合には、容器本体を真空二重構造とすることができる。飲料容器の本体を二重構造として内部を真空にする方法としては、従来公知の方法から適宜選択して採用することができる。たとえば、特許文献１および２を参照することもできる。 When the inside of the beverage container of the present invention is made into a double structure and the inside is evacuated, the heat retaining property can be improved. Therefore, when the heat retaining property is particularly important, the container body can have a vacuum double structure. . As a method of making the body of the beverage container a double structure and evacuating the inside, it can be appropriately selected from conventionally known methods. For example, Patent Documents 1 and 2 can be referred to.
　本発明の飲料容器本体の両端開口部には、蓋体が取り付けられる。両端開口部に取り付けられた蓋体は、本体内に収容された飲料が漏れない構造のものであればよく、従来公知の蓋体構造のものから適宜選択して採用することができる。 A lid is attached to both ends of the beverage container body of the present invention. The lids attached to the opening portions at both ends may be of any structure as long as the beverage accommodated in the main body does not leak, and can be appropriately selected from conventionally known lid structures.
　また、蓋体を構成する材質は特に制限されるものではなく、従来公知の蓋体に使用されている材質から適宜選択して使用することができる。このような蓋体の好ましい材質として、樹脂を挙げることができる。 Further, the material constituting the lid is not particularly limited, and can be appropriately selected from materials conventionally used for lids. A preferable material for such a lid is a resin.
　本発明の蓋体を構成する樹脂としては、とくに制限はなく、従来飲料容器の蓋体に使用されている樹脂から適宜選択して使用することができる。蓋体に使用することができる樹脂の例としては、高分子量ポリエチレンなどのポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリスチレン、ＡＢＳ樹脂、ポリエステル、アクリル樹脂、ポリ塩化ビニリデン、ポリカーボネート、ポリアミドポリアセタール、フェノール樹脂、メラミン樹脂、ユリア樹脂、ポリウレタン、エポキシ樹脂などを挙げることができるが、これに限定されるものではない。 The resin constituting the lid of the present invention is not particularly limited, and can be appropriately selected from resins conventionally used for lids of beverage containers.
