〔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
とともに、胴部中央部にラベル表示があり、また、底部
に異材質のベースカップを嵌着してあるプラスチックボ
トルの再利用方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for reusing plastic bottles that are no longer needed due to molding defects, etc., and in particular, the present invention relates to a method for reusing plastic bottles that are no longer needed due to molding defects, etc. This invention relates to a method for reusing plastic bottles that are labeled and have a base cup made of a different material fitted to the bottom.
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、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, the method of reusing this type of plastic bottle that has been molded poorly or is no longer used is to cut the bottle above the label, then crush the upper part of the bottle above the cut part and reuse it as molding material. However, the center and bottom of the bottle were simply discarded.
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であるため、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
とろく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
まうこととなリ、極めて不経済である。The reason for this treatment is that the label display part is printed or pasted, so it is impossible to reuse that part, and the bottom of the bottle is fitted with a base cup made of a different material. This is because it is impossible to simultaneously crush and reuse the bottle, but such a processing method results in 60% to 70% of the entire bottle being 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
供仕んとするものである。The present invention was devised in view of these points, and aims to provide a method for effectively reusing unnecessary plastic bottles.
本発明において再利用すべきプラスチックボトルは、上

プ４を接着したものである。In the present invention, the plastic bottle to be reused has a spout 5 at the top, a label at the middle part 2 of the body, and a base cup 4 made of a different material fitted to the bottom of the bottle. The base cup 4 is attached by applying 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、゛’、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。When reusing the bottle, first, the bottle is cut at the upper and lower parts of the label 6, and the middle part 2 of the bottle body with the label displayed is discarded. This is because if the label is printed, the ink adheres to the surface of the bottle body, making it unsuitable for reuse as a molding material, and if the label 6 is attached, the label , 6 is not easy to peel off, and even if it could be removed, it is not suitable as a molding material because it has adhesive attached 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

はベースカップ４をボトル底部中央に接着剤で接着して
いる部分をくり抜けばベースカップ４をボトル底部３か
ら容易に離脱でき、また、くり抜き部分７には接着剤が
あって再利用に適さないからである。Next, the center of the bottle bottom 3 is hollowed out together with the base cup 4, and the hollowed out portion is discarded. The reason for this is that the base cup 4 can be easily removed from the bottle bottom 3 by hollowing out the part where the base cup 4 is glued to the center of the bottom of the bottle, and the hollow part 7 has an adhesive that can be reused. This is because 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 the base cup 4 is removed from the bottle bottom 3, the bottle top 1, the bottle bottom 3, and the base cup 4 are crushed and reused as molding material.
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, parts that were conventionally discarded are also reused, reducing the amount of wasted parts.
以下、本発明の一実施例を図面に基づいて説明する。 Hereinafter, one embodiment of the present invention will be described based on 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

レート製の試験管状をしたプリフォームをエアープロ一
方式で２軸延伸して成型したもので、その上部には口筒

酸飲料充填用として耐圧性能を向上させるためで、ベー
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, to explain about the plastic bottle that should be reused, this plastic bottle is made by biaxially stretching a test tube-shaped preform made of polyethylene terephthalate using an air processor. is formed, and the middle part 2 of the body is slightly constricted, and a label 6 is attached to that part with adhesive.The bottom part 3 is formed in a spherical shape, and since it would fall over if left as is, the bottom A generally flat base cup 4 made of polyethylene is fitted onto the bottle bottom 3, and the center of the bottom of the bottle and the inner bottom surface of the base cup 4 are bonded with adhesive. Here, the reason why the bottom surface is made spherical is to improve the pressure resistance for filling carbonated drinks, and the reason why the base cup 4 is fitted is to lean the bottle against it as described above and to protect 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は
、成型過程で不良が生じ、そのままでは清涼飲料水など
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れ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 a plastic bottle should be reused is when a defect occurs during the molding process and the bottle cannot be filled with soft drinks, etc., or even if it can be filled, it is not suitable for sale as a product. case or
This is the case when a bottle has already been filled with soft drinks, etc. and sold, and then the soft drinks, etc. have been 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ｌ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、ボトル
底部３はベースカップ４を接着するために接着剤を塗布
してある底部中央をベースカップ４とともにくり抜き、
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, I will explain how to reuse the bottle. First, cut the bottle at the upper and lower parts of the label and make 3 parts.
, 2. Divide into 3. The top part of the bottle 1 is crushed and reused as a plastic material, but the bottom part 3 of the bottle is hollowed out along with the base cup 4 at the center of the bottom where adhesive has been applied to attach the base cup 4.
The hollowed out part 7 is disposed of, and since the remaining bottle bottom part 3 and base cup 4 have no adhesive part and can be easily separated, they are crushed separately and reused as 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 of hollowing out the bottom of the bottle, see Figure 1 (C
), using a press punching device.
そして、ボトルの内設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１にｇ当たり ４
０Ｑ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７９
＝ ２．８円、ベースカップ部のポリエチレンが約１２
９＝ ２．７円となり、ボトル１本当たり５．５円分従
来より節約できも。And by reusing the thick bottom of the bottle, the amount of polyethylene terephthalate is reduced by 1 to 4 grams per gram.
If 0Q yen and polyethylene is 225 yen per kg, the polyethylene terephthalate at the bottom of the bottle is approximately 79 yen.
= 2.8 yen, the polyethylene of the base cup is about 12
9 = 2.7 yen, which means you can save 5.5 yen per bottle.
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 of a bottle, which was conventionally discarded, and it is economical and resource saving can be achieved. Also,
Since the center of the bottom of the bottle is hollowed out, the base cup can be easily removed and reused.
