Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は成型不良等で不要となったプラスチックボトル
の再利用方法に関し、とりわけ、上部に口筒部を有する

トルの再利用方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for reusing a plastic bottle that is no longer needed due to defective molding or the like, and in particular, has a mouth tube part on the upper part and a label on the center part of the body part. The present invention also relates to a method of reusing a plastic bottle having a label and a base cup made of a different material fitted on the bottom.

〔従来の技術〕[Conventional technology]

従来、この種のプラスチックボトルであって成型不良や
使用済みとなったものの再利用方法は、ラベルの上側で
ボトルを切断して、切断部分より上のボトル上部は粉砕
して成型材料として再利用するが、ボトルの中央部と底
部はそのまま廃棄してしまっていた。Conventionally, this type of plastic bottle that has been molded defective or has been used is reused by cutting the bottle on the upper side of the label and crushing the upper part of the bottle above the cut part and reusing it as a molding material. However, the center and bottom of the bottle had been discarded.

〔発明が解決すべき問題点〕[Problems to be solved by the invention]

このように処理する理由は、ラベル表示部分はラベルを
印刷もしくは張り付けてあるため、その部分の再利用は
不可能であること、ボトル底部には異材質のベースカッ
プが嵌着されているため、同時に粉砕して再利用するこ
とができないこと等の理由からであるが、このような処
理方法ではボトル全体の60％〜70％を廃棄してしまうこ
ととなり、極めて不経済である。The reason for processing in this way is that since the label is printed or pasted on the label, it is not possible to reuse that part, and since the base cup made of a different material is fitted to the bottom of the bottle, This is because it cannot be crushed and reused at the same time, but with such a treatment method, 60% to 70% of the entire bottle is discarded, which is extremely uneconomical.

本発明は、このような点に鑑みなされたもので、不要と
なったプラスチックボトルを有効に再利用する方法を提
供せんとするものである。The present invention has been made in view of the above circumstances, and an object thereof is to provide a method for effectively reusing an unnecessary plastic bottle.

〔問題点を解決するための手段〕[Means for solving problems]

本発明において再利用すべきプラスチックボトルは、上
部に口筒部５を有するとともに、胴部中間部２にラベル

着し、ボトルの底部中央に接着剤を塗布してベースカッ
プ４を接着したものである。The plastic bottle to be reused in the present invention has a mouth tube portion 5 on the upper portion, a label is displayed on the middle portion 2 of the body portion, and a base cup 4 made of a different material is fitted on the bottom portion of the bottle. The base cup 4 is adhered by applying an adhesive to the center.

そして、再利用にあたっては、まず、ラベル６の上側と
下側部分でボトルを切断して、ラベル表示のあるボトル
胴部中間部２を廃棄する。これは、ラベル表示が印刷の

め成型材料として再利用に適さず、また、ラベル６を張
り付けたものである場合はラベル６を剥がすのが容易で
はなく、たとえ剥がせたとしても接着剤が付着している
ため成型材料として適さないからである。Then, for reuse, first, the bottle is cut at the upper and lower parts of the label 6, and the bottle body middle part 2 with the label is discarded. This is not suitable for reuse as a molding material because the ink adheres to the surface of the bottle body when the label is printed, and the label 6 is peeled off when the label 6 is stuck. This is because it is not easy to use, and even if it can be peeled off, it is not suitable as a molding material because the adhesive adheres to it.

次に、ボトル底部３はベースカップ４とともにその中央

あって再利用に適さないからである。Next, the bottom portion 3 of the bottle and the base cup 4 are hollowed out at the central portion, and the hollowed-out portion is discarded. The reason is that the base cup 4 can be easily detached from the bottle bottom 3 by removing the part where the base cup 4 is adhered to the center of the bottom of the bottle with an adhesive, and the hollow part 7 has an adhesive for reuse. It is not suitable for.

そして、ボトル底部３からベースカップ４を離脱した
後、前記ボトル上部１とボトル底部３とベースカップ４
とをそれぞれ粉砕して、成型材料として再利用する。After removing the base cup 4 from the bottle bottom 3, the bottle top 1, the bottle bottom 3 and the base cup 4 are removed.
And are crushed and reused as molding materials.

〔作用〕[Action]

本発明によれば、従来廃棄していた部分も再利用するの
で、無駄になる部分が少なくなった。According to the present invention, since the portion which has been conventionally discarded is reused, the wasted portion is reduced.

〔実施例〕〔Example〕

以下、本発明の一実施例を図面に基づいて説明する。 An embodiment of the present invention will be described below with reference to the drawings.

まず、再利用すべきプラスチックボトルについて説明す

スカップ４を嵌着したのは前記の如くボトルを立て掛け
るためと、底部３の保護のためである。First, the plastic bottle to be reused will be described. This plastic bottle is a polyethylene terephthalate test tube-shaped preform which is biaxially stretched and molded by an air blow method. In addition to being formed, the middle part 2 of the body part is slightly constricted and the label 6 is attached to that part with an adhesive, and the bottom part 3 is formed in a spherical shape, so it will fall down as it is, so the bottom surface is A polyethylene base cup 4 which is flat as a whole is fitted to the bottle bottom portion 3, and the central portion of the bottom portion of the bottle and the inner bottom surface of the base cup 4 are bonded with an adhesive. Here, the spherical bottom surface is for improving the pressure resistance performance for filling the carbonated beverage, and the base cup 4 is fitted for leaning the bottle as described above and for protecting the bottom portion 3. .

このようなプラスチックボトルを再利用すべきときと

どを充填できなかったり、たとえ充填できたとしても商
品として販売するにはふさわしくないものである場合
や、既に清涼飲料水等を充填して販売された後に清涼飲
料水等を飲み切ってボトルのみが廃棄物として回収され
た場合等である。When such a plastic bottle should be reused, a defect occurs in the molding process and it cannot be filled with soft drinks as it is, or even if it can be filled, it is not suitable for sale as a product. This is the case when the soft drinks, etc. have already been filled and sold and then the soft drinks, etc. have been completely consumed and only the bottles are collected as waste.

次に、再利用方法について述べると、まず、ラベルの上
側の部分と下側の部分でボトルを切断して３つの部分
１、２、３に分断する。その内、ボトル上部１はそのま
ま粉砕してプラスチック材料として再利用するが、ボト

き、そのくり抜き部分７は廃棄処分とし、残余のボトル
底部３とベースカップ４とは接着部分がなくなり容易に
離脱するので、それぞれ別にして粉砕し、成型材料とし
て再利用する。Next, the recycling method will be described. First, the bottle is cut at the upper part and the lower part of the label and divided into three parts 1, 2, 3. Among them, the bottle upper part 1 is crushed as it is and reused as a plastic material, but the bottle bottom part 3 is hollowed out with the base cup 4 at the center of the bottom part to which an adhesive is applied to adhere the base cup 4, and the hollowed part 7 is discarded, and since the remaining bottle bottom 3 and the base cup 4 are easily separated from each other because there is no adhesive portion, they are crushed separately and reused as a molding material.

なお、ボトル底部をくり抜く手段としては、第１図
（Ｃ）に示すように、プレス打ち抜き装置による。As a means for hollowing out the bottom of the bottle, a press punching device is used as shown in FIG. 1 (C).

そして、ボトルの内最も厚肉の底部を再利用することに
より、ポリエチレンテレフタレートが1kg当たり400円、
ポリエチレンが1kg当たり225円とすると、ボトル底部の
ポリエチレンテレフタレートが約7g＝2.8円、ベースカ
ップ部のポリエチレンが約12g＝2.7円となり、ボトル１
本当たり5.5円分従来より節約できる。And by reusing the thickest bottom of the bottle, polyethylene terephthalate is 400 yen per kg,
If polyethylene is 225 yen per kg, polyethylene terephthalate at the bottom of the bottle will be about 7g = 2.8 yen and polyethylene at the base cup will be about 12g = 2.7 yen.
You can save more than 5.5 yen per book.

〔発明の効果〕〔The invention's effect〕

本発明によれば、従来捨てていたボトルの底部を再利用
でき、経済的で、省資源化を図ることができる。また、
ボトル底部中央をくり抜くようにしたので、ベースカッ
プの取り外しが容易で、再利用が容易になった。According to the present invention, it is possible to reuse the bottom portion of a bottle that has been thrown away, which is economical and saves resources. Also,
Since the center of the bottom of the bottle is hollowed out, the base cup can be easily removed and reused.
