【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ボトル本体にそれとは別体の把手を取付け
た把手付きプラスチックボトルに関する。Description: BACKGROUND OF THE INVENTION The present invention relates to a plastic bottle with a handle having a separate handle attached to the bottle body.
プラスチックボトルは、大型化すると取扱いが不便に
なるので、把手を一体成形したボトルが洗剤用などとし
て使用されている。ところが、ポリエチレンテレフタレ
ート（PET）のようなポリエステル樹脂製ボトルにおい
ては、把手をボトル本体と一体成形することが難しいの
で、ボトル本体の上部側面に別体の把手を取付けて一体
化することが行われており、把手部材に設けた突起等に
ボトル本体の壁部を係合させることにより取付けてい
る。（特開昭58−99350号公報参照） 〔発明が解決しようとする課題〕 しかしながら、上記ボトル本体に別体の把手を取付け
たものでは、次のような欠点がある。即ち、ボトル本体
の壁部は、ボトル外面側にいくにつれてブロー成形時の
延伸倍率が大きくなるため、把手部材に設けた突起等に
係合させようとすると、壁部の材料が変形しにくく十分
な形状に成形できず、その肉厚も極めて薄いものにな
り、取付け強度が不十分であった。Since the handling of plastic bottles becomes inconvenient when the size is increased, bottles integrally formed with a handle are used for detergents and the like. However, in the case of a polyester resin bottle such as polyethylene terephthalate (PET), it is difficult to integrally mold the handle with the bottle body, so a separate handle is attached to the upper side surface of the bottle body and integrated. It is mounted by engaging the wall of the bottle body with a projection or the like provided on the handle member. [Problem to be Solved by the Invention] However, the one in which a separate handle is attached to the bottle main body has the following disadvantages. That is, since the stretching ratio at the time of blow molding becomes larger toward the outer surface side of the bottle, the material of the wall portion is not easily deformed when trying to engage with a projection provided on the handle member. It could not be formed into a suitable shape, the thickness was extremely thin, and the mounting strength was insufficient.
そこで本発明は、上記ボトル本体壁部と把手との係合
構造を改善し、より取付け強度に優れた把手取付け構造
を有するプラスチックボトルを提供することを目的とし
ている。Accordingly, an object of the present invention is to provide a plastic bottle having a handle mounting structure with improved mounting strength by improving the engagement structure between the bottle body wall and the handle.
上記した目的を達成するために、本発明の把手付きプ
ラスチックボトルは、ボトル本体に、握り部と、該握り
部から横方向に突出した嵌着部と、該嵌着部の先端に設
けた係止突起とを有する把手部材を取付けた把手付きプ
ラスチックボトルにおいて、取付部ではボトル本体壁部
が前記係止突起を包み込むように係合しているととも
に、前記係止突起の横断面形状を、ボトル中心側が長辺
となる台形状に形成したことを特徴としている。In order to achieve the above object, a plastic bottle with a handle according to the present invention includes a handle provided on a bottle body, a fitting portion protruding laterally from the handle, and a fitting provided at a tip of the fitting portion. In a plastic bottle with a handle to which a handle member having a stop projection is attached, a bottle main body wall portion is engaged with the attachment portion so as to wrap the engagement protrusion, and a transverse cross-sectional shape of the engagement protrusion is set to the bottle. It is characterized in that it has a trapezoidal shape with the long side on the center side.
以下、本発明を、図面に示す一実施例に基づいて、さ
らに詳細に説明する。Hereinafter, the present invention will be described in more detail based on one embodiment shown in the drawings.
第１図は把手付きプラスチックボトルを示す断面図、
第２図は第１図のII−II断面図、第３図は把手の斜視図
である。FIG. 1 is a sectional view showing a plastic bottle with a handle.
FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a perspective view of the handle.
第１図に示すように、把手付きプラスチックボトル１
は、ボトル本体２の上部側面３にボトル本体２とは別体
に形成した把手４を取付けたものである。As shown in FIG. 1, a plastic bottle 1 with a handle
In the figure, a handle 4 formed separately from the bottle body 2 is attached to the upper side surface 3 of the bottle body 2.
把手４は、握り部41と、該握り部41の上下両端部から
横方向、ボトル中心側に突出した嵌着部42,42と、該嵌
着部42の先端部からそれぞれボトルの上下方向に突出し
た係止突起43,43とから構成されている。The handle 4 includes a grip portion 41, fitting portions 42, 42 projecting laterally from the upper and lower ends of the grip portion 41 and toward the center of the bottle, and a vertical direction of the bottle from the tip end of the fitting portion 42. The locking projections 43 are protruded.
そして、上記係止突起43は、ボトル中心側が長辺とな
る台形状、即ち、ボトル径方向にある両短手側縁44を、
ボトル中心側が広く、外周側が狭くなるように傾斜さ
せ、ボトル接線方向の長手側縁45を略平行にして、横断
面形状が台形になるようにしている。The locking projection 43 has a trapezoidal shape in which the bottle center side is a long side, that is, both short side edges 44 in the bottle radial direction
The bottle is inclined such that the center side of the bottle is wide and the outer periphery side is narrow, and the longitudinal side edges 45 in the tangential direction of the bottle are substantially parallel, so that the cross-sectional shape is trapezoidal.
この把手４は、上記係止突起43が前記ボトル本体２の
上部側面３の壁部に食い込んだ状態で埋め込まれてボト
ル本体２に取付けられる。The handle 4 is embedded and attached to the bottle main body 2 in a state where the locking projections 43 bite into the wall of the upper side surface 3 of the bottle main body 2.
係止突起43の形状を、上記のような台形状にしたの
で、ボトル本体２の壁部を係止突起43の周面に、ボトル
中心側の長手側縁45からすぐに十分に回り込ませること
ができる。また、ボトル本体２の壁部に変形を生じた場
合でも、壁部が係止突起43に、食込むように回り込んで
いるので外れにくくなる。Since the shape of the locking projection 43 is trapezoidal as described above, the wall of the bottle main body 2 can be sufficiently and immediately wrapped around the peripheral surface of the locking projection 43 from the longitudinal side edge 45 on the center side of the bottle. Can be. In addition, even when the wall of the bottle body 2 is deformed, the wall is wrapped around the locking projection 43 so as to cut into the locking projection 43, so that the bottle hardly comes off.
従って、把手４に形成する係止突起43を、嵌着部42の
先端部に設けるとともに、その横断面形状を上記のよう
な台形状とすることにより、把手取付け強度の向上が図
れる。Therefore, by providing the locking projection 43 formed on the handle 4 at the distal end of the fitting portion 42 and making the cross-sectional shape of the trapezoidal shape as described above, the handle mounting strength can be improved.
尚、係止突起43の形状は、その長手側縁45が嵌着部42
の幅と同じであっても、嵌着部42より横方向に突出して
いても良い。また、完全な台形である必要はなく、曲面
や折曲げ部を有していても良い。また、第３図に示すよ
うに、嵌着部42の先端側面に、横方向の突起46を設け
て、さらに取付け強度を大きくすることもできる。さら
に、ボトル本体２の形状や成形方法、これに伴う把手４
の取付け方法は任意であり、様々な方法で行うことがで
きる。たとえば把手４を、嵌着部42が型内面に突出する
ようにブロー型に固着した状態でボトル本体２をブロー
成形することにより壁部を嵌着部42に回り込ませて取付
けることができる。The shape of the locking projection 43 is such that its long side edge 45 is
May be the same as the width, or may protrude laterally from the fitting portion. Further, it is not necessary to have a complete trapezoidal shape, and it may have a curved surface or a bent portion. Further, as shown in FIG. 3, a lateral protrusion 46 may be provided on the side surface of the distal end of the fitting portion 42 to further increase the mounting strength. Furthermore, the shape and molding method of the bottle body 2 and the accompanying handle 4
The method of mounting is arbitrary, and can be performed in various ways. For example, when the handle 4 is fixed to a blow mold so that the fitting portion 42 projects to the inner surface of the mold, the bottle body 2 is blow-molded, so that the wall portion can be wrapped around the fitting portion 42 and attached.
以上説明したように、本発明の把手付きプラスチック
ボトルは、把手の嵌着部先端に形成した断面台形の係止
突起を本体の壁部に埋め込むように係合したので、該係
止突起を確実に埋め込むことができ、抜け難くなるの
で、把手取付け強度を向上でき、左右のがたつきやボト
ル本体の変形による把手の抜け落ちを防止できる。As described above, in the plastic bottle with a handle of the present invention, the locking projection having a trapezoidal cross section formed at the tip of the fitting portion of the handle is engaged so as to be embedded in the wall of the main body. The handle can be attached easily, and the handle mounting strength can be improved, and the handle can be prevented from dropping due to rattling on the left and right or deformation of the bottle body.
