Abstract

PROBLEM TO BE SOLVED: To provide a PET bottle in which a consumer's troublesome work for peeling off labels at the time of classifying PET bottles is eliminated and their improvement of classification and recycling efficiency is adapted.SOLUTION: There is provided a displaying method in which some requisite descriptions such as a name, names of raw materials, quantity, open date, a maker's name and the like are carve-printed through direct heat treatment or carve-printed through molding against a bottle 2, wherein no labels are applied and the constitution of PET bottle is composed of a cap and a bottle.

Description

本発明は、リサイクル可能な容器として広く普及しているペットボトルに関するものである。  The present invention relates to a PET bottle that is widely used as a recyclable container.

ペットボトルは、清涼飲料、酒類、食用油、化粧品等の容器として使用されており、軽くて持ちやすい、再栓性がある、衝撃に強い、透明度が高い、衛生上も安全といった優れた特徴を有しており、ボトル用ペット樹脂の需要は年々増加している。  PET bottles are used as containers for soft drinks, alcoholic beverages, edible oils, cosmetics, etc., and have excellent characteristics such as light and easy to hold, re-pluggable, strong against impact, high transparency, and hygienic safety. The demand for PET resin for bottles is increasing year by year.

一方、資源の有効活用の観点から、使用後のペットボトルは分別収集され、再生工場でリサイクルされる。  On the other hand, from the viewpoint of effective use of resources, used PET bottles are collected separately and recycled at a recycling plant.

さらに、近年、地球温暖化などの環境問題に係る意識は高まり、資源の有効利用の一つとしてのペットボトルのリサイクルが推進され、それに伴いペットボトルの自主設計ガイドラインも改定が繰り返されている。  Furthermore, in recent years, awareness of environmental issues such as global warming has increased, and recycling of PET bottles has been promoted as one of the effective use of resources. In accordance with this, self-design guidelines for PET bottles have been revised.

上記ペットボトルは、主にキャップ、ボトル、ラベルの3つの部材で構成されており、特に清涼飲料、しょうゆ、酒類、ドレッシング等用途のペットボトルは、キャップがPP(ポリプロピレン)またはPE(ポリエチレン)製で、ボトル本体はPET(ポリエチレンテレフタレート)製、またラベルはPE製のものが主となっている。そのため、分別時にはキャップをはずしてラベルを剥がし、ボトルをペットとして、キャップおよびラベルをプラスチックとして分別するのが一般的であり、非常に手間がかかるためリサイクル率の普及を妨げている一因と言える。  The above PET bottles are mainly composed of three parts: caps, bottles, and labels. Especially for plastic bottles for soft drinks, soy sauce, liquors, dressings, etc., the caps are made of PP (polypropylene) or PE (polyethylene). The bottle body is mainly made of PET (polyethylene terephthalate), and the label is mainly made of PE. For this reason, it is common to remove the cap and remove the label at the time of separation, to separate the bottle as a pet, and the cap and label as plastic. .

そこで、ペットボトルの構成部材分別を簡便にし、リサイクルされやすいように、ペットボトルに様々な工夫が提案されている。 特許文献1には、ボトルおよびキャップ全体をラベルで覆い、開栓時にラベルの一部を剥がしておくことで非分別を防ぐことが提案されている。また、特許文献2には、消費者が容易に剥がすことができるよう改良された熱収縮性ラベルおよび製造方法が開示されている。そのほか、ラベルを剥がすための器具やラベル剥ぎ口の改良について特許文献3〜5に開示してあるがリサイクル率向上の大きな改良には至っていない。  In view of this, various ideas have been proposed for PET bottles in order to simplify the separation of the constituent parts of the PET bottles and to facilitate recycling. Patent Document 1 proposes to prevent unseparation by covering the entire bottle and cap with a label and removing a part of the label at the time of opening. Patent Document 2 discloses a heat-shrinkable label and a manufacturing method improved so that the consumer can easily peel off. In addition, Patent Documents 3 to 5 disclose improvements in instruments for peeling labels and label peeling openings, but they have not yet greatly improved the recycling rate.

消費者にとって、ラベルを剥がすという行為は非常に手間に思える作業であり、従来、剥がしやすいラベルが提案されてきたが目立った改良には至っていない。また、環境問題の解決意識への高まりから、ペットボトルの分別およびリサイクル率の向上はさらに重要な問題になると考えられ、リサイクルに対応したペットボトルの設計が求められる。  For consumers, the act of removing the label is a very time-consuming task, and a label that is easy to remove has been proposed in the past, but has not been noticeably improved. In addition, as the awareness of solving environmental problems rises, the separation of PET bottles and the improvement of the recycling rate are considered to become even more important problems, and the design of PET bottles corresponding to recycling is required.

本発明のペットボトルは、係る課題を解決するものであり、従来から提案されているラベルの改良とは大きく異なり、必要な表示事項をボトルに直接熱加工による刻印印字または金型成型により刻印印字することによる表示で、ラベル用いず、ペットボトルの構成をキャップとボトルとにするものである。  The PET bottle of the present invention solves such a problem, and is greatly different from the conventionally proposed improvement of the label, and the necessary display items are directly printed on the bottle by stamping or stamping by die molding. In this display, the label is not used, and the configuration of the plastic bottle is a cap and a bottle.

本発明のペットボトルは、ラベル表示をなくし、ボトル本体に直接熱加工印字あるいは成型加工刻印印字を使用して、名称・原材料名・内容量・賞味期限・製造元等必要な表記事項をボトル本体に直接加工処理して表示されることにより、リサイクルためのラベルとボトルの分離作業をなくしたリサイクル性の高いペットボトルである。  The PET bottle of the present invention eliminates the label display and directly uses the heat processing printing or molding stamping printing on the bottle body, and the necessary notation items such as name, raw material name, content volume, expiration date, manufacturer, etc. are displayed on the bottle body. By being directly processed and displayed, it is a highly recyclable PET bottle that eliminates the separation work of labels and bottles for recycling.

すなわち、本発明のラベルレスのペットボトルを使用することにより、消費者がペットボトル使用後に必要であったラベルを剥がす作業そのものを無くすことによって、ラベルを剥がす手間を省き、分別されていないペットボトルの量を減らし、リサイクル率を上げることができる。また、ラベルを無くすことにより、ラベル印刷に用いる着色成分を不要とし、ラベル自体のゴミの量も減らすことができ、いっそう環境に良い商品設計となる。  In other words, by using the label-less PET bottle of the present invention, by eliminating the work itself for removing the label that the consumer needed after using the PET bottle, the effort to remove the label is saved, and the PET bottle is not separated. Can reduce the amount of waste and increase the recycling rate. Further, by eliminating the label, the coloring component used for label printing is unnecessary, the amount of dust on the label itself can be reduced, and the product design is further improved in the environment.

以下に、本発明のペットボトルについて詳細に説明する。  Below, the PET bottle of this invention is demonstrated in detail.

図1は、本発明を適用したペットボトルの構成の一例を示す模式図である。本発明に係るリサイクル対応型ペットボトルは、キャップおよびボトルで構成されており、例えば、ボトルに炭酸ガスレーザーで直接印字しているため、別途印刷されたPE製ラベルを必要としないことを特徴とするものである。  FIG. 1 is a schematic diagram showing an example of the configuration of a plastic bottle to which the present invention is applied. The recyclable PET bottle according to the present invention is composed of a cap and a bottle. For example, since the bottle is directly printed with a carbon dioxide laser, it does not require a separately printed PE label. To do.

キャップは、従来使用されているようにプラスチックキャップが好ましく、分別の際にPETと混ざらないようにするためPEまたはPPを主材とした比重1.0未満のプラスチックキャップ、中栓、ライナーのものが特に好ましい。  The cap is preferably a plastic cap as used in the past, and is made of a plastic cap having a specific gravity of less than 1.0, an inner plug and a liner mainly composed of PE or PP so as not to be mixed with PET at the time of separation. Is particularly preferred.

ボトルは、従来使用されるPET単体の無色透明のものがリサイクル可能であるため好ましい。なお、ボトルの形状としては、特に限定されるものではなく、胴部が丸形および角形のどちらでも構わない。  As the bottle, a colorless and transparent PET alone used conventionally is preferable because it can be recycled. The shape of the bottle is not particularly limited, and the body may be round or square.

ボトルへの加熱加工刻印印字方法としては、樹脂用マーカーとして用いられる炭酸ガスレーザーマーカーおよび成形用金型を用いた刻印が挙げられる。炭酸ガスレーザーは、立体的なボトルの表面にも鮮明に印字することができる。 一方、成形用金型は、ボトルの射出成形と同時に必要表記事項を刻印することができる。これら2種の印字方法は、単独で使用することもできるし、組み合わせて使用してもよい。  Examples of the heat-processed marking printing method on the bottle include a carbon dioxide laser marker used as a resin marker and a marking using a molding die. The carbon dioxide laser can clearly print on the surface of a three-dimensional bottle. On the other hand, the molding die can be stamped with necessary notation items simultaneously with the bottle injection molding. These two types of printing methods can be used alone or in combination.

また、有機溶剤や金属粉を含有したインクや接着剤を使用するものとは異なり、キャップとボトルを分離するだけで、リサイクルに際して不純物の混入がなく、環境への負荷もない。  In addition, unlike the case of using an ink or an adhesive containing an organic solvent or metal powder, only the cap and the bottle are separated, and no impurities are mixed during recycling, and there is no burden on the environment.

さらに従来のラベルを省略した分、ゴミの量を減らすこと(リデュース)もでき、環境へ配慮されたペットボトル設計となる。  Furthermore, the amount of garbage can be reduced (reduced) by omitting the conventional label, and the environment-friendly PET bottle design is achieved.

図2は、炭酸ガスレーザーにより刻印印字されたラベルレスペットボトルの1例を示す写真であり、鮮明な認識が確認できる。  FIG. 2 is a photograph showing an example of a label-less PET bottle that is engraved and printed by a carbon dioxide laser, and a clear recognition can be confirmed.

本発明のリサイクル対応型ペットボトルは、清涼飲料、しょうゆ、酒類、ドレッシング等の容器として利用できる。さらにはボトルにラベルを貼り付けるまたは熱収縮ラベルを使用するすべての用途のPET製容器として利用できる。  The recyclable PET bottle of the present invention can be used as a container for soft drinks, soy sauce, alcoholic beverages, dressings and the like. Furthermore, it can be used as a PET container for all uses in which a label is attached to a bottle or a heat-shrink label is used.
