Description

【０００１】
【発明の属する技術分野】
本発明は、把手体および該把手体をボトル本体に取り付けた把手付プラスチックボトルに関する。
【０００２】
【従来の技術】
近年、ガラスにくらべて軽量で耐衝撃性の大きいポリエチレンテレフタレートで代表されるポリエステル樹脂などのプラスチックからなるボトル本体に、それとは別体の把手を取り付けた把手付プラスチックボトルが実用化され、なかでもボトル本体の側面に形成した把手取り付け用凹部に、握り部と該握り部の上下両側から横方向に突出する取り付け腕を備えた把手を、前記取り付け腕の先部を把手取り付け用凹部内のボトル壁に埋め込むようにして取り付けてなる把手付プラスチックボトルが市場に流通している。
【０００３】
この把手付プラスチックボトルは、図３に正面断面図を示すように、ブロー成形用型の中に、あらかじめ別体の把手体３をその取り付け腕３２、３３の先部をブロー成型用型内に突出するようセットしておき、そのブロー成形用型の中でボトル本体１をブロー成形すると同時に、ボトル壁２０により取り付け腕３２、３３の先部を包み込むようにして一体化する方法で製造されている。そして、取り付け腕３２、３３の先部には突出片３２１、３３０が形成され、この突出片３２１、３３０もボトル壁２０に埋め込むようにして抜け止め作用を果たしている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の把手付プラスチックボトルは、特に把手体３の材質としてボトル本体１と同様の材質等、互いに滑りが悪い樹脂を選択した場合、下側取り付け腕３３の下方に接するボトル壁２０１が極めて薄くなり、穴が開きやすくなるなど、ボトル強度や、把手の取り付け強度に不安が生じるという問題があった。
【０００５】
【課題を解決しようとする手段】
本発明者等は、上記課題を解決しようと鋭意検討の結果、把手体の材質がボトル本体と互いに滑りが悪い樹脂の場合、ボトル本体をブロー成形すると同時に把手体と一体化する際に、ボトル壁と把手体の下側取り付け腕先部の下側突出片とが摩擦を生じ、傷付いたり、過延伸になったりして、ボトル壁が外側ほど薄くなりやすいことを見出だし、本発明に到達したものであり、その要旨は、握り部と、該握り部の上下両側から横方向に突出する取り付け腕とを備えた把手体において、上側取り付け腕及び下側取り付け腕の先部の上側に前記握り部とほぼ平行に立ち上がる突出片を設け、下側取り付け腕の突出片は該下側取り付け腕先端の幅の３０〜７０％である狭幅に形成するとともに、下側取り付け腕の上面両側縁は面取り部としたことを特徴とする把手体およびボトル本体の側面に形成した把手取り付け用凹部に、握り部と該握り部の上下両側から横方向に突出する取り付け腕を備えた把手体を、前記取り付け腕の先部を把手取り付け用凹部内のボトル壁に埋め込むようにして取り付けてなる把手付プラスチックボトルにおいて上側取り付け腕及び、下側取り付け腕の先部の上側に前記握り部とほぼ平行に立ち上がる突出片を設け、下側取り付け腕の突出片は該下側取り付け腕先端の幅の３０〜７０％である狭幅に形成するとともに、下側取り付け腕の上面両側縁は面取り部としたことを特徴とする把手付プラスチックボトルである。
【０００６】
本発明によれば、本発明の把手体および把手付プラスチックボトルは、把手体の下側取り付け腕の先部の上側に該下側取り付け腕より狭幅の突出片を形成するとともに、下側取り付け腕の上面両側縁は面取り部としたから、ボトル本体をブロー成形すると同時に把手と一体化する際に、突出片が狭幅な分だけボトル壁は被さりやすく、しかも被さった先端の大きく引き伸ばされたボトル壁が、下側取り付け腕の上面両側縁に接触したとき、面取り部としたことにより鋭い応力が加わらないため、破れたりしにくいとともに、突出片が上向きなので通常の取扱いで上向きの力が加わっても外れにくという効果を奏するものである。
【０００７】
【発明の実施の形態】
以下、本発明を図面を参照して更に詳細に説明する。
【０００８】
図１は本発明の把手付プラスチックボトルの一例を示す一部切り欠いた側面部分断面図、図２（ａ）は図１における把手の一例を示す正面図であり、図２（ｂ）は図２（ａ）の側面図、図２（ｃ）は図２（ｂ）のＣーＣ断面図である。
【０００９】
本発明は、図１〜２に示すように、握り部３１と、該握り部３１の上下両側から横方向に突出する取り付け腕３２、３３とを備えた把手体３において、上側取り付け腕及び下側取り付け腕３３の先部の上側に前記握り部とほぼ平行に立ち上がる突出片を設け、下側取り付け腕の突出片は該下側取り付け腕３３の先端の幅の３０〜７０％である狭幅の突出片３３１を形成するとともに下側取り付け腕３３の上面両側縁は面取り部１２とした把手体３およびボトル本体１の側面に形成した把手取り付け用凹部２に、握り部３１と該握り部３１の上下両側から横方向に突出する取り付け腕３２、３３を備えた把手体３を、前記取り付け腕の先部を把手取り付け用凹部２内のボトル壁２０に埋め込むようにして取り付けてなる把手付プラスチックボトルにおいて、下側取り付け腕３３の先部の上側に該下側取り付け腕３３より狭幅の突出片３３１を形成するとともに、下側取り付け腕３３の上面両側縁は面取り部１２としたことを特徴とする把手付プラスチックボトルである。
【００１０】
本発明における把手体３は、要するに図２に示すように握り部３１と、該握り部３１の上下両側から横方向に突出する取り付け腕３２、３３とを備え、該下側取り付け腕より狭幅の突出片３３１を形成するとともに、下側取り付け腕３３の上面両側縁は面取り部１２とした基本形状であればよい。
突出片３３１の幅ｗ1は、下側取り付け腕３３の先端の幅ｗ0の３０％乃至７０％程度が好ましい。
また、下側取り付け腕３３の幅ｗ0としては通常２０〜３０ｍｍ、突出片３３１の高さｈ1は２〜５ｍｍ、幅ｗ1は５〜１５ｍｍの範囲とするのが好ましい。高さｈ1が２ｍｍに満たなかったり、幅ｗ1が５ｍｍに満たない場合、ボトル壁２０との噛み合い量が少なすぎて、抜け止め効果が不十分となるおそれがあり、高さｈ1が５ｍｍを越えたり、幅ｗ1が１５ｍｍを越えた場合、ボトル壁２０が突出片３３１を充分に乗り越えることができず、取り付け腕３３上面との間に間隙ができて外観が悪くなったり、抜け止め効果が悪化するおそれもでるので上記範囲が好ましい。
【００１１】
面取り部１２は、ボトル壁２０が突出片３３１を乗り越えて接触する範囲を考慮して、下側取リ付け腕３３の先端から１５ｍｍ以内に形成するのが好ましい。また、その形状は、例えばＣーＣ断面形状で、幅ｗ2と高さｈ2の比ｗ2／ｈ2が略２（水平に対する角度が２０°〜３０°）になるような傾斜面とし、その両端１２１、１２２を曲線で仕上げた形状が好適である。
【００１２】
さらに、また面取り部１２の幅ｗ2は、その部分の把手幅ｗ c の５〜１５％程度が好ましい。突出片３３１のボトル本体と接する表面部分あるいは、取り付け腕３３の下面の表面部分に、図示しないが、しぼ模様、梨地模様、格子模様あるいは条溝模様等の小凹凸を形成して、すべりを良くしてもよい。
【００１３】
その場合小凹凸の高さとしては０．０５〜０．０１ｍｍ、好ましくは０．０５〜０．５ｍｍの範囲から選択できる。
【００１４】
この小凹凸を付設するためには、把手体の射出成形型に、対応する小凹凸を彫り込んでおいて成形と同時に付設したり、成形後のサンドブラスト加工や切削加工により付設してもよい。
【００１５】
本発明のボトル本体は、プラスチック、例えばポリエチレンテレフタレートで代表されるポリエステル樹脂を用いて、まず、射出成形により中間製品である管状素材４（以下、プリフォームという。）を形成し、ついで、該プリフォーム４を延伸温度、例えばポリエチレンテレフタレートの場合は９０〜１２０℃まで加熱した状態でブロー成形型内にセットし、前記プリフォーム４内に高圧空気などを吹き込んで２軸延伸ブロー成形して得られる。
【００１６】
本発明において、把手体はポリエチレンテレフタレートで代表されるポリエステル樹脂、ポリプロピレン、ポリエチレンなどが使用できる。
【００１７】
特に、把手体の材質としてボトル本体と同様のポリエステル樹脂を採用すると、回収してリサイクルする際に、本体と一緒に処理することができ、また把手体として再生樹脂を使用することができるので好ましい。
【００１８】
【実施例】
以下、本発明を実施例により更に具体的に説明する。
【００１９】
（実施例１）
図１に示すように、あらかじめブロー成形用型内に、図２に示すような、握り部３１と該握り部３１の上下両側から横方向に突出する取り付け腕３２、３３を備え、突出片３３１の高さｈ１が３ｍｍ、幅ｗ１が１０ｍｍ、面取り部１２は、例えば下側取り付け腕３３の先端から８ｍｍの部分のＣーＣ断面形状で、幅ｗ2が２ｍｍ、高さｈ2が１ｍｍの傾斜面とし、その内端１２１がｒ＝１ｍｍ、外端１２２がｒ＝５ｍｍの曲線で仕上げてあるポリプロピレン製およびポリエチレンテレフタレート製の把手体３をセットし、重量５０ｇのポリエチレンテレフタレート製のプリフォーム４を９５℃に加熱してブロー成形したところ、ポリプロピレン製の把手もポリエチレンテレフタレート製の把手も、下側取り付け腕３３の下方の、ボトル壁２０の最も薄い部分が０．１ｍｍの厚さを保ち、まったく孔は生じなかった。
【００２０】
（比較例１）図３に示す従来の把手体３、すなわち取り付け腕３３の先部には下側に突出片３３０が形成されている把手体１を用いたほかは、実施例と同様の条件でブロー成形したところ、ポリプロピレン製の把手体３の場合は、下側取り付け腕３３の下方のボトル壁２０１に孔は生じなかったが、その最も薄い部分が０．０５ｍｍの厚さまで薄くなり、ポリエチレンテレフタレート製の把手体の場合は下側取り付け腕３３の下方のボトル壁２０１に孔が生ずるものがあった。

BACKGROUND OF THE INVENTION
The present invention relates to a handle body and a plastic bottle with a handle in which the handle body is attached to a bottle body.
[0002]
[Prior art]
In recent years, plastic bottles with grips with a separate handle attached to the bottle body made of plastic such as polyester resin represented by polyethylene terephthalate, which is lighter and more impact resistant than glass, have been put to practical use. A grip provided with a grip and a mounting arm projecting laterally from both the upper and lower sides of the grip on the grip mounting recess formed on the side surface of the bottle body, the bottle at the tip of the mounting arm in the grip mounting recess Plastic bottles with handles, which are attached so as to be embedded in walls, are available on the market.
[0003]
As shown in the front cross-sectional view of FIG. 3, this plastic bottle with a handle has a separate handle body 3 in advance in the blow molding mold, and the tips of its mounting arms 32 and 33 are placed in the blow molding mold. The bottle body 1 is blow-molded in the blow-molding mold, and at the same time, it is manufactured by a method in which the front ends of the attachment arms 32 and 33 are wrapped by the bottle wall 20 and integrated. Yes. Protruding pieces 321 and 330 are formed at the front portions of the mounting arms 32 and 33, and the protruding pieces 321 and 330 are also embedded in the bottle wall 20 so as to prevent detachment.
[0004]
[Problems to be solved by the invention]
However, the above-described conventional plastic bottle with a handle has a bottle wall 201 that is in contact with the lower side of the lower mounting arm 33, particularly when a resin that is not slippery, such as the same material as the bottle body 1, is selected as the material of the handle body 3. There was a problem that the bottle strength and the attachment strength of the handle were uneasy, such as being extremely thin and easily opening a hole.
[0005]
[ Means to solve the problem]
As a result of intensive studies to solve the above problems, the present inventors have determined that when the material of the handle body is a resin that does not slide with the bottle body, the bottle body is blow-molded and integrated with the handle body at the same time. It has been found that the wall and the lower projecting piece of the lower attachment arm tip of the handle body are rubbed, scratched or overstretched, and the bottle wall tends to become thinner toward the outside. In a grip body having a grip portion and mounting arms projecting laterally from both the upper and lower sides of the grip portion, the gist thereof is above the tip portions of the upper mounting arm and the lower mounting arm. A protruding piece that rises substantially parallel to the grip portion is provided, and the protruding piece of the lower mounting arm is formed to have a narrow width that is 30 to 70% of the width of the tip of the lower mounting arm, and both upper surface sides of the lower mounting arm. The edge is a chamfer A grip body having a grip and a mounting body projecting laterally from both the upper and lower sides of the grip portion in a grip mounting recess formed on a side surface of the grip body and the bottle body, and a tip portion of the mounting arm In a plastic bottle with a handle attached so as to be embedded in the bottle wall in the handle mounting recess, an upper mounting arm and a protruding piece that rises substantially parallel to the grip portion are provided above the tip of the lower mounting arm. The protruding piece of the side mounting arm is formed to have a narrow width which is 30 to 70% of the width of the tip of the lower mounting arm, and both side edges of the upper surface of the lower mounting arm are chamfered plastics It is a bottle.
[0006]
According to the present invention, the handle body and the plastic bottle with the handle of the present invention form a protruding piece narrower than the lower mounting arm on the upper side of the lower mounting arm of the grip body, Since both sides of the upper surface of the arm are chamfered, when the bottle body is blow-molded and integrated with the handle, the bottle wall is easily covered by the narrow width of the protruding piece, and the covered tip is greatly stretched. When the bottle wall comes into contact with both side edges of the upper surface of the lower mounting arm, sharp stress is not applied due to the chamfered portion, so it is difficult to break and the upward force is applied during normal handling because the protruding piece is upward. However, it has the effect of being hard to come off.
[0007]
