Description

适用于保特瓶的瓶盖及其制造方法
技术领域
本发明是关于一种适用于保特瓶的瓶盖及其制造方法。 背景技术
目前巿面上所见的保特瓶， 是指利用 PET ( polyethylene terephthalate , 聚对苯二甲酸乙二醇酯）材质所制成的容器， 而保特瓶的瓶盖， 多是利用 HDPE ( High Density Polyethylene, 高密度聚乙烯）材质或 PP (聚丙烯）材 质所制成， 而非利用 PET。
原因在于， PET质地较硬， 若应用于射出成型形成瓶盖， 技术上有所 困难， 例如饱压时间过长、 硬度太高不易后续机械加工等问题， 而普遍不 为业界所釆用。
然而， 目前广泛使用的保特瓶， 却存在着回收耗能的问题。 乃因瓶盖 开启后，其机械带会断裂而残留在瓶身上， 而该机械带与瓶盖同样为 HDPE 或 PP材质， 与保特瓶本身并不相同， 而无法一并回收再利用， 因此一般皆 须额外将机械带与瓶身相互分离后才可对 PET材质的瓶身进行后续处理。
常用分离方式， 有以手工去除机械带与瓶身标签的， 但如此会需要大 量人工， 致使人力成本增加。 另外也有将回收的保特瓶打碎放入水中， 利 用比重差异而分离不同材质， 然回收后的 PET瓶片需除水干燥， 也有耗能 过大的问题。 发明内容
本发明的主要目的即是为了改善常用保特瓶不利回收的问题。
本发明的另一主要目的是为了提供一种利于机械加工的 PET瓶盖。 为了达成上述目的， 本发明提供了一种适用于保特瓶的瓶盖制造方法， 包括:
一混熔步骤， 为调制一浆料， 该浆料含有 PET原料、 增塑剂及纳米粘 土； 以及
一射出成型步骤， 将该浆料射出成型， 得到一瓶盖。
为了达成上述目的， 本发明提供了一种适用于保特瓶的瓶盖， 其是由
PET原料、 增塑剂及纳米粘土所制成。
以此， 令该瓶盖利于后续机械加工， 且其材质与保特瓶相同而大幅减 低保特瓶回收的难度， 并且降低回收成本。

首先， 请参考图 1。 本发明提供了一种适用于保特瓶的瓶盖制造方法， 其包括一混熔步骤 10、 一射出成型步骤 20、 一折边步骤 30以及一切线步 骤 40。
该混熔步骤 10主要是调制一浆料， 该浆料含有 PET原料、 增塑剂 11 及纳米粘土 12。 更明确地说， 该浆料可利用 PET塑胶粒 13混掺增塑剂 11 及纳米粘土 12后， 再经双螺杆混炼机或其他类型混炼机混炼制得； 或者， 该浆料亦可于前端制作 PET时添加， 亦即将增塑剂 11及纳米粘土 12添加 入乙二醇 14及对苯二甲酸 15—并混炼制得。 依上述两种方法制得浆料后， 可直接进行该射出成型步骤 20, 但亦可另行将浆料重新造粒以便储存、 运 输， 后续再将该改质后的 PET塑胶粒重新混熔， 进行该射出成型步骤 20。 其中， 该增塑剂的增加可令瓶盖易于成型， 而该纳米粘土 12例如是将蒙脱 土进行脱层后取得， 且经由毒性测试后， 已证实该纳米粘土 12的添加并不 会产生毒性， 可应用于瓶装饮料的瓶盖； 此外， 该纳米粘土 12还具有良好 的抗冲击、 抗疲劳及阻气性等， 还可适用于啤酒等酒类容器的瓶盖， 令保 特瓶可望取代铝罐、 玻璃瓶等成为啤酒的盛装容器。
该射出成型步骤 20, 是将该浆料射出成型， 得到一瓶盖。 请参考图 2 及图 3, 于该射出成型步骤 20中， 该瓶盖于底缘还一并射出形成一环形机 械带 2, 于该机械带 2底缘还形成一环形的可挠转板 4。
该折边步骤 30, 主要是在该瓶盖与保特瓶瓶口结合后， 将该可挠转板 4折入该瓶盖中心方向， 形成一倒勾， 即如图 4所示。
该切线步骤 40, 则是在机械带 2与瓶盖底缘之间环状切开数道不连续 的切线 6, 即如图 5及图 6所示。 以此， 当使用者旋开瓶盖时， 该可挠转板 4会如图 7与图 8所示而与瓶口卡抵无法脱出，致使机械带 2自瓶盖底缘脱 离。 在本发明的瓶盖制造方法中， 该瓶盖内还可设有一内垫， 设于瓶口与 瓶盖之间， 用以提升该保特瓶的气密性。 较佳者， 该内垫亦是釆用混掺有 增塑剂及纳米粘土的 PET材质所制成。
本发明通过在 PET原料中混掺增塑剂及纳米粘土， 除了可增加其加工 性能之外， 还解决了常用保特瓶回收处理过程中需除去非 PET材质机械带 的困扰， 因为本发明的瓶盖与保特瓶皆为相同材质所致； 而通过添加纳米 粘土， 还可增强 PET的纤维强度， 可令回收抽丝作业时不致断线。
综合上述， 本发明所提供的瓶盖及其制造方法， 不仅技术新颖实用， 还具有显著进步的功效， 并改善本领域长期存在的问题。
