Description
本考案は、エチレン酢酸ビニル共重合体を主体とする組成物に帯電防止剤を含有させた樹脂からなる成形品であって、携帯型通信端末器の液晶画面を除く部分を覆い得るようにした携帯型通信端末器用のカバーに関するものである。 The present invention is a molded product made of a resin containing an antistatic agent in a composition mainly composed of an ethylene vinyl acetate copolymer, and can cover a portion other than a liquid crystal screen of a portable communication terminal. The present invention relates to a cover for a portable communication terminal.
携帯電話、多機能携帯電話（いわゆるスマートフォン）、ＰＨＳなど、各種の携帯型通信端末器の普及に伴って、近年、それを覆うことができるカバーが種々開発され、商品としても爆発的に売れている。
このような状況下、材質がシリコーンゴム製（例えば、特許文献１参照）や、軟質合成樹脂製その他種々の材質からなるものが提案されている。
With the widespread use of various portable communication terminals such as mobile phones, multi-function mobile phones (so-called smart phones), and PHS, in recent years, various covers that can cover them have been developed and sold explosively as products. Yes.
Under such circumstances, materials made of silicone rubber (see, for example, Patent Document 1), soft synthetic resin, and other various materials have been proposed.
このような材質からなる場合には、携帯型通信端末器保護の機能は十分であろうが、帯電防止機能に関しては十分であるとは言い難い。冬になるほど、静電気が発生しやすいので、携帯型通信端末器を持ったときに不快な静電気を手に感じることが多い。 When made of such a material, the function of protecting the portable communication terminal will be sufficient, but it is difficult to say that the antistatic function is sufficient. In winter, static electricity is more likely to be generated, so unpleasant static electricity is often felt in the hand when holding a portable communication terminal.
そこで、本考案者は、カバーを特別の材質からなるものとすれば、この欠点を解消し得ることに気付き、本考案を完成するに至った。
Therefore, the present inventor has realized that this drawback can be eliminated if the cover is made of a special material, and the present invention has been completed.
すなわち、本考案による携帯型通信端末器用カバーは、エチレン酢酸ビニル共重合体を主体とする組成物に帯電防止剤を含有させた樹脂からなる成形品であって、携帯型通信端末器Ｂの液晶画面ｂを除く部分を覆い得るように、底板１の周囲に枠体２を備えたことを特徴とするものである。
That is, the cover for a portable communication terminal according to the present invention is a molded product made of a resin containing an antistatic agent in a composition mainly composed of an ethylene-vinyl acetate copolymer, and is a liquid crystal of the portable communication terminal B. The
携帯型通信端末器用カバーがエチレン酢酸ビニル共重合体を主体とする組成物に帯電防止剤を含有させた樹脂からなる成形品である場合には、帯電防止機能が極めて優れたものとなる。また、このカバーの他の特長は、軟らかく、しかも、極めて軽いことである。 When the cover for the portable communication terminal is a molded product made of a resin containing an antistatic agent in a composition mainly composed of an ethylene vinyl acetate copolymer, the antistatic function is extremely excellent. Another feature of this cover is that it is soft and extremely light.
本考案によれば、帯電防止機能が極めて優れたカバーを安価に提供することができる。また、このカバーは軟らかく、しかも、極めて軽いものである。 According to the present invention, a cover having an extremely excellent antistatic function can be provided at low cost. Also, this cover is soft and extremely light.
本考案による携帯型通信端末器用カバーの一例を、図面に基づいて詳細に説明する。本考案による携帯型通信端末器用カバーＡは、少なくとも、エチレン酢酸ビニル共重合体を主体とする組成物に帯電防止剤を含有させた樹脂からなる成形品であり、その主成分の中に、エチレンプロピレンゴムを含有させることができ、全てを一体的に成形することができる。 An example of a portable communication terminal cover according to the present invention will be described in detail with reference to the drawings. A cover A for a portable communication terminal according to the present invention is a molded article made of a resin containing an antistatic agent in a composition mainly composed of an ethylene vinyl acetate copolymer. Propylene rubber can be contained, and all can be molded integrally.
図面に示すように、携帯型通信端末器の１つである多機能携帯電話（いわゆるスマートフォン）Ｂを覆う場合を例に挙げて説明すると、この多機能携帯電話Ｂの液晶画面ｂを除く部分を覆い得るように、底板１の周囲に枠体２を備えたものとなっている。さらに詳しく説明すると、ほぼ方形状である多機能携帯電話Ｂの形状に合致するごとく、カバーＡもほぼ方形状としてあり、さらに、多機能携帯電話Ｂの裏面を覆う底板１の四周に、多機能携帯電話Ｂの四つの側面ｂ’部分を囲繞し得る枠体２を備えている。
As shown in the drawing, a case where a multi-function mobile phone (so-called smart phone) B that is one of portable communication terminals is covered will be described as an example. A portion excluding the liquid crystal screen b of the multi-function mobile phone B will be described. A
このようにすれば、ほぼ方形状である多機能携帯電話Ｂの液晶画面ｂを除く部分をカバーＡですっぽりと覆うことができ、カバーＡがエチレン酢酸ビニル共重合体を主体とする組成物に帯電防止剤を含有させた樹脂からなっているから、多機能携帯電話Ｂを持っても、不快な静電気を手に感じることを防止でき、帯電防止機能が極めて優れている。 In this way, the portion excluding the liquid crystal screen b of the multi-function mobile phone B having a substantially rectangular shape can be covered completely with the cover A, and the cover A becomes a composition mainly composed of an ethylene vinyl acetate copolymer. Since it is made of a resin containing an antistatic agent, even if you have the multifunctional mobile phone B, you can prevent it from feeling unpleasant static electricity, and the antistatic function is extremely excellent.
また、このカバーＡは軟らかく、しかも、極めて軽いものである。しかも、このカバーＡは安価である。 The cover A is soft and extremely light. Moreover, this cover A is inexpensive.
多機能携帯電話Ｂの様々な機能に合わせて、カバーＡの底板１のそれぞれの位置には様々な形状の孔３〜７や、枠体２のそれぞれの位置には様々な形状の孔８，９などが設けられている。
In accordance with various functions of the multi-function mobile phone B, holes 3 to 7 having various shapes are provided at the positions of the
カバーＡがこのようになっていると、このカバーＡで多機能携帯電話Ｂの液晶画面ｂを除く部分をすっぽりと覆ったとしても、カバーＡ付きでも多機能携帯電話Ｂの様々な機能が損なわれることがない。 When the cover A is like this, even if the cover A completely covers the portion other than the liquid crystal screen b of the multi-function mobile phone B, various functions of the multi-function mobile phone B are impaired even with the cover A. It will not be.
図示はしないが、他の携帯型通信端末器、例えば、携帯電話やＰＨＳの形状に合わせて、カバーＡの形状を決定することができ、また、携帯電話やＰＨＳの機能に合わせて、カバーＡに形成する孔の形状や数を決定することができる。 Although not shown, the shape of the cover A can be determined according to the shape of another portable communication terminal, for example, a mobile phone or PHS, and the cover A can be determined according to the function of the mobile phone or PHS. The shape and number of holes to be formed can be determined.
エチレン酢酸ビニル共重合体としては、例えば、東ソー株式会社のウルトラセン５４０、同６３１、同６４０、同６３４などを用いることができ、帯電防止剤としては、ドデシルベンゼンスルホン酸ナトリウム塩（例えば、竹本油脂株式会社製のエレカットＳ−４１２−２）を用いることができる。 As the ethylene vinyl acetate copolymer, for example, Ultrasene 540, 631, 640, and 634 of Tosoh Corporation can be used, and as the antistatic agent, sodium dodecylbenzenesulfonate (for example, Takemoto) Elecut S-412-2) manufactured by Yushi Co., Ltd. can be used.
なお、上記エチレン酢酸ビニル共重合体を主体とする組成物１００重量パーセントに対して、上記帯電防止剤（竹本油脂株式会社製のエレカットＳ−４１２−２）を４重量パーセント含有させた樹脂から携帯型通信端末器用カバーＡを作製し、ＪＩＳ Ｋ６９１１に準拠して電気抵抗計で当該カバーＡの表面固有抵抗値を測定すると、帯電防止特性に優れていることが分かった。 In addition, it is carried from a resin containing 4% by weight of the antistatic agent (Elecut S-412-2 manufactured by Takemoto Yushi Co., Ltd.) with respect to 100% by weight of the composition mainly composed of the ethylene vinyl acetate copolymer. When the cover A for type communication terminals was produced and the surface resistivity of the cover A was measured with an electric resistance meter in accordance with JIS K6911, it was found that the antistatic property was excellent.
