Description

【０００１】
【発明の属する技術分野】
本発明はプラスチックボトル用把手及びボトル本体の側面に把手取付け用凹部を形成し、該把手取付け用凹部に把手を取付けた把手付きプラスチックボトルに関する。
【０００２】
【従来の技術】
従来、把手付きプラスチックボトルはボトル本体１の側面に把手取付け用凹部を形成し、握り部とその上下の取付け腕からなる別体の把手を、前記取付け腕の先端に設けた係止突部を把手取付け用凹部内の壁面に埋め込むようにして取付けたものが広く実施されている。
【０００３】
これらの把手付きプラスチックボトルを製造する方法として、あらかじめ把手をブロー成形金型にセットしておき、ブロー成形と同時にボトル本体の壁を把手の取付け係止突部に巻き付かせてこれを埋め込むようにするいわゆるインサート成形が行われている。
【０００４】
そして、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製のボトル本体に、同じくポリエステル樹脂製の把手を取付けたボトルが、使用後、把手と本体とを分離せずに再処理して再利用できることから脚光を浴びている。
【０００５】
【発明が解決しようとする課題】
しかしながら、特にポリエステル樹脂からなるボトル本体に、同じくポリエステル樹脂からなる把手を、インサート成形しようとすると、同質の樹脂同士で滑りが悪いので、成形し易くするため下側取付け腕の先端に設ける係止突部を上向きに形成して滑り抵抗を減らす場合があり、そうすると取付け強度が低下するという問題があった。
【０００６】
本発明は前記の問題点を解決した把手のボトル本体への取付け強度に優れた把手付きプラスチックボトルを提供することを目的とする。
【０００７】
【課題を解決するための手段】
前記の目的は以下の手段によって達成される。
【０００８】
すなわち、本発明は、握り部とその上下の取付け腕を有し、上下の取付け腕先端に上向きに突出した係止突部を設けてなり、下の取付け腕先端の係止突部先端に握り部方向に突条を形成した突出部を設けたことを特徴とするプラスチックボトル用把手を提案するものである。
【０００９】
また、本発明は握り部とその上下の取付け腕を有し、上下の取付け腕先端に上向きに突出した係止突部を設けてなり、下の取付け腕先端の係止突部の先端両側に突起を形成した突出部を設けたことを特徴とするプラスチックボトル用把手を提案するものである。
【００１０】
さらに、本発明は、ボトル本体の側面に把手取付け用凹部を形成し、該把手取付け用凹部のボトル壁面を前記の把手の係止突部に巻き付けると共に突出部の下側に食い込むようにして巻き付けて把手を取付けたことを特徴とする把手付きプラスチックボトルを提案するものである。
【００１１】
【発明の実施の形態】
以下、本発明を図面を参照してさらに詳細に説明する。
【００１２】
図１はプラスチックボトル用把手の一例を示す斜視図であり、図２は把手の他の例を示す部分図、図３は把手付きプラスチックボトルの一部切り欠いた正面図、図４は下取付け腕３３付近の部分断面図である。
【００１３】
本発明のプラスチックボトル用把手は図１に示すように握り部３１と、その上下の取付け腕３２，３３からなり、上下取付け腕３２，３３先端に設けた係止突部３４の先端には突出部３５を設けてある。
【００１４】
図１の例では突出部３５は係止突部３４の先端から握り部３１方向に突条を形成することにより設けてある。また図２に示すように係止突部３４の先端両側に突起を形成して突出部３５を設けてもよい。
さらに、図示しないが突出部としては係止突部を先端側に行くにつれて徐々に傾斜させたり広げたりすることにより突出させるようにしてもよい。
【００１５】
このように係止突部３４に突出部３５を設けた把手３を図３のようにボトル本体１の側面に形成した把手取付け用凹部２の壁面２１に埋め込むように取付けると、図４に示すように突出部３５の存在による壁面２１に対するアンカー効果により把手３の取付け強度を大幅に向上することができるものである。
【００１６】
特に把手３をインサート成形によりボトル本体１に取付ける場合は、図４に示すように係止突部３４が上向きに取付けられており、下取付け腕３３の下面には突部が無い分だけ滑り抵抗が少ないから係止部３４と成形時の壁面２１との結合が極めて円滑に行われると共に、係止突部３４に巻き付いた壁面２１はさらに突出部３５の下側に食い込むように巻き付くから下向きの応力に対してアンカー効果が作用し抜けにくくなって取付け強度を大幅に向上することができる。
【００１７】
【発明の効果】
本発明によれば係止突部の先端に突出部を形成することにより把手の取付け強度を大幅に向上することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a plastic bottle handle and a plastic bottle with a handle in which a handle mounting recess is formed on a side surface of the bottle body, and the handle is mounted in the handle mounting recess.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a plastic bottle with a handle has a recess for attaching a handle on the side surface of the bottle body 1, and a separate handle consisting of a grip portion and upper and lower mounting arms is provided with a locking projection provided at the tip of the mounting arm. Widely implemented are those embedded so as to be embedded in the wall surface in the handle mounting recess.
[0003]
As a method of manufacturing these plastic bottles with a handle, the handle is set in advance in a blow mold, and the wall of the bottle body is wrapped around the handle mounting and locking protrusion at the same time as the blow molding and embedded. So-called insert molding is performed.
[0004]
For example, a bottle with a polyester resin handle attached to a polyester resin bottle main body represented by polyethylene terephthalate can be reused by reprocessing without separation of the handle and main body after use. Have been bathed.
[0005]
[Problems to be solved by the invention]
However, when trying to insert-mold a handle made of polyester resin, especially on a bottle body made of polyester resin, slipping between the same quality resins is bad, so the locking provided at the tip of the lower mounting arm for easy molding There is a case where the protrusion is formed upward to reduce the slip resistance, which causes a problem that the mounting strength is lowered.
[0006]
It is an object of the present invention to provide a plastic bottle with a handle that is excellent in strength to be attached to a bottle body of a handle that solves the above-mentioned problems.
[0007]
[Means for Solving the Problems]
The above object is achieved by the following means.
[0008]
That is, the present invention has a mounting arm of the grip portion and the upper and lower, it is provided a locking projection which is upwardly protruding above and below the mounting arm tip, grip the locking projection tip of the mounting arm tip of the lower The present invention proposes a plastic bottle handle characterized in that a protrusion having a protrusion formed in the part direction is provided.
[0009]
Further, the present invention has a grip portion and upper and lower mounting arms, and is provided with locking projections protruding upward at the upper and lower mounting arm tips, on both sides of the distal end of the locking projection at the lower mounting arm tip. The present invention proposes a handle for a plastic bottle, characterized in that a protrusion having a protrusion is provided.
[0010]
Further, according to the present invention, a recess for attaching the handle is formed on the side surface of the bottle body, and the bottle wall surface of the recess for attaching the handle is wound around the locking projection of the handle and is wound around the lower side of the projection. The present invention proposes a plastic bottle with a handle characterized by having a handle attached.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
[0012]
1 is a perspective view showing an example of a handle for a plastic bottle, FIG. 2 is a partial view showing another example of the handle, FIG. 3 is a front view of a plastic bottle with a handle, and FIG. 4 is a partial cross-sectional view in the vicinity of an arm 33. FIG.
[0013]
As shown in FIG. 1, the handle for a plastic bottle of the present invention comprises a grip portion 31 and upper and lower mounting arms 32 and 33, and protrudes from the distal ends of locking projections 34 provided at the distal ends of the upper and lower mounting arms 32 and 33. A portion 35 is provided.
[0014]
In the example of FIG. 1, the protrusion 35 is provided by forming a protrusion from the tip of the locking protrusion 34 toward the grip 31. Further, as shown in FIG. 2, protrusions 35 may be provided by forming protrusions on both sides of the distal end of the locking protrusion 34.
Further, although not shown, the protruding portion may be protruded by gradually inclining or expanding the locking protrusion as it goes to the distal end side.
[0015]
When the handle 3 provided with the protrusion 35 on the locking protrusion 34 is attached so as to be embedded in the wall surface 21 of the handle mounting recess 2 formed on the side surface of the bottle body 1 as shown in FIG. 3, it is shown in FIG. Thus, the attachment strength of the handle 3 can be significantly improved by the anchor effect on the wall surface 21 due to the presence of the protruding portion 35.
[0016]
In particular, when the handle 3 is attached to the bottle body 1 by insert molding, as shown in FIG. 4, the locking projection 34 is attached upward, and the lower attachment arm 33 has a slip resistance corresponding to the absence of the projection. Since the engagement portion 34 and the wall surface 21 at the time of molding are very smoothly joined together, the wall surface 21 wound around the engagement projection 34 further wraps so as to bite below the projection 35 and is downward. The anchor effect acts against the stress of this, making it difficult to pull out, and the mounting strength can be greatly improved.
[0017]
【The invention's effect】
According to the present invention, the attachment strength of the handle can be greatly improved by forming the protrusion at the tip of the locking protrusion.
