Description
【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取手を取付けたプ
ラスチックボトルに関する。TECHNICAL FIELD The present invention relates to a plastic bottle in which a handle which is separate from the bottle is attached to the bottle body.
（従来の技術） 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、取手を一体成形したボトルが洗剤用等として使用

面図により示すようにボトル本体１の上方に取手取付用
凹部２を形成し、その凹部２に別体の取手３をその上下
端部を固定して取り付けたボトルが提案されている。(Prior Art) Since a plastic bottle becomes inconvenient to handle when it is upsized, a bottle with a handle integrally formed is used for a detergent or the like. However, in a polyester resin bottle such as polyethylene terephthalate, it is difficult to integrally mold the handle with the bottle body, so that the handle mounting recess 2 is formed above the bottle body 1 as shown in the front view in FIG. However, there is proposed a bottle in which a separate handle 3 is attached to the recess 2 with its upper and lower ends fixed.

た。(Problems to be Solved by the Invention) However, in the above-mentioned conventional one, since the recess wall surface is recessed inward, the distance bulged from the parison during blow molding is short and the draw ratio is low. For this reason, indefinite deformation due to the degree of orientation and shape difference from other parts is likely to occur, and the entire bottle is tilted or the concave part is deformed and the concave part opening is deformed, resulting in a gap in the mounting part of the handle 3. There was a problem.
（課題を解決するための手段） 本発明は取手の剛性により変形のアンバランスを解消し
て上記問題点を解決せんとしたものであり、以下添付図
面に基づいて説明する。(Means for Solving the Problems) The present invention is intended to solve the above problems by eliminating the imbalance of deformation due to the rigidity of the handle, and will be described below with reference to the accompanying drawings.

FIG. 4 is a front view with a part cut away, and FIG. 4 is a front view showing an example of a conventional plastic bottle with a handle.
本発明は、第１〜３図に示すとおりボトル本体１の上部

止部31,32を、凹部開口部の上下外側面21,22に埋設した
ことを特徴とする取手付プラスチックボトルである。According to the present invention, as shown in FIGS. 1 to 3, a recess 2 for attaching a handle is formed on the upper side surface of the bottle body 1, and the handle 3 is provided in the recess.
3 in the plastic bottle that is attached
A plastic bottle with a handle, characterized in that a pair of engaging portions 31, 32 formed in the upper and lower end portions in a direction facing each other are embedded in the upper and lower outer surfaces 21, 22 of the recess opening portion.
取手の上下両端部に互いに向き合う方向に形成した一対

たる凹部開口部の上下外側面21,22に埋設したから、取
手の剛性により凹部２の上下方向の寸法変化を有効に抑
制することができる。Since the pair of locking portions 31 and 32 formed in the upper and lower end portions of the handle in a direction facing each other are embedded not in the upper and lower surfaces of the recess but in the upper and lower outer surfaces 21 and 22 of the recess opening corresponding to the side surface, the rigidity of the handle It is possible to effectively suppress the vertical dimension change of the recess 2.
第1,2図の例では、取手３の上下端にボトル内方に突出
する鉤形の係止部31,32を備え、この係止部31,32がそれ

口部上下に有効に作用し凹部が伸縮しようとするのを開
口部で抑制して、ボトル全体の不定変形に至らぬように
阻止し、さらに外側面から係止して取手が固定されてい
るので凹部開口部が拡がって取手がはずれたりしない。In the example shown in FIGS. 1 and 2, hook-shaped locking portions 31 and 32 projecting inward of the bottle are provided at the upper and lower ends of the handle 3, and these locking portions 31 and 32 are respectively the outer side surfaces 21 and 22 above and below the concave portion. It is buried so as to cut into the wall of the. As a result, the handle 3 is firmly fixed to the bottle body 1, and the rigidity of the handle 3 effectively acts above and below the opening of the recess 2 to prevent the recess from expanding and contracting in the opening, and thus the entire bottle. Since the handle is fixed by locking it from the outer side surface, the recess opening does not expand and the handle does not come off.
第３図の例では、取手の上下両端部に互いに向き合う方
向に形成した一対の係止部31,32の他に取手３の上下端

起34を設けてあり、係止部31,32と係止突起34とにより
凹部の外側面と奥との間でしめつけるようにするので、
いっそう確実に固定できる。In the example of FIG. 3, in addition to the pair of locking portions 31 and 32 formed in the upper and lower end portions of the handle in a direction facing each other, the arm portion 33 extending to the inner part of the recess 2 and the tip end of the arm portion 33 extending in the back of the handle 3 Since the locking projection 34 is provided and the locking portions 31, 32 and the locking projection 34 are used to tighten the space between the outer surface and the inner side of the recess,
Can be fixed more securely.
取手３の外面はボトル本体１の外面とほぼ面一になるよ
うにして、保管、運搬スペースを取らないようにするの
がよく、そのため凹部２は取手３を取り付けた時に取手
３と凹部２との間に形成される空間に手指が充分入る程
度の大きさが好ましい。It is preferable that the outer surface of the handle 3 is substantially flush with the outer surface of the bottle body 1 so as to save space for storage and transportation, and therefore the recess 2 is formed so that the handle 3 and the recess 2 are formed when the handle 3 is attached. The size is preferably large enough to fit the fingers into the space formed between the two.
通常のボトルにおいて、凹部２の深さはボトル本体１上
部の径の1/4〜1/3程度とするのがよい。また、取手３は
ボトル本体とは別体のものであればよく、たとえばポリ
エチレン、ポリプロピレンなどのプラスチックを射出成
形して剛性を持たせたものなどが用いられる。In a normal bottle, the depth of the recess 2 is preferably about 1/4 to 1/3 of the diameter of the upper portion of the bottle body 1. Further, the handle 3 may be provided separately from the bottle body, and for example, a plastic such as polyethylene or polypropylene injection-molded to have rigidity is used.
このようなボトルを製造するためには、例えばボトルの
ブロー成形金型内に予め取手３をセットしておき、ボト

2等を包み込むようにすればよい。In order to manufacture such a bottle, for example, the handle 3 is set in advance in a blow molding die of the bottle, the bottle is blow molded, and the bottle locking wall holds the grips 31,3.
You should wrap the 2nd grade.

止することができるという作用効果を奏する。(Effect of the Invention) As described above, the plastic bottle with a handle of the present invention has the recess 2 for mounting the handle formed on the upper side surface of the bottle body 1,
In a plastic bottle in which the handle 3 is mounted in the recess, a pair of locking portions 31, 32 formed in the upper and lower end portions of the handle 3 in directions facing each other are embedded in the upper and lower outer surfaces 21, 22 of the recess opening. Therefore, the difference in the degree of stretching of the upper side surface caused by the concave portion for attaching the handle to the bottle, the difference in the degree of expansion and contraction due to the shape imbalance, etc. is suppressed by effectively utilizing the rigidity of the handle and adjusted. It is possible to prevent an indefinite deformation of the bottle due to heat, an external force, an internal pressure, or the like, and to prevent an empty space between the handle attachment portion and the bottle.
