具体实施方式
以下是通过特定的具体实施例来说明本发明所公开的实施方式，本领域技术人员可由本说明书所公开的内容了解本发明的优点与效果。本发明可通过其他不同的具体实施例加以施行或应用，本说明书中的各项细节也可基于不同观点与应用，在不悖离本发明的构思下进行各种修改与变更。另外，本发明的附图仅为简单示意说明，并非依实际尺寸的描绘，事先声明。以下的实施方式将进一步详细说明本发明的相关技术内容，但所公开的内容并非用以限制本发明的保护范围。
应当可以理解的是，虽然本文中可能会使用到“第一”、“第二”、“第三”等术语来描述 各种组件或者信号，但这些组件或者信号不应受这些术语的限制。这些术语主要是用以区分一组件与另一组件，或者一信号与另一信号。另外，本文中所使用的术语“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。
[隐形眼镜的包装容器]
如图1及图2所示，本发明的实施例提供一种隐形眼镜包装容器100，所述包装容器100具有一盛装部1、一环绕部2及一封装部3。所述盛装部1呈凹陷状、且用以盛装隐形眼镜及缓冲溶液。所述环绕部2呈扁平状、且一体成型地环绕于所述盛装部1的周围。所述封装部3为封装薄膜，其是用以将隐形眼镜及缓冲溶液封装于盛装部1中。值得一提的是，本发明实施例所提供的隐形眼镜包装容器100能具有缤纷的色彩，并且能对特定波长的光线产生阻挡能力。
如图3所示，所述包装容器100是由一塑料材料a及分散于所述塑料材料a中的一色粉材料b所形成。特别是包装容器100的盛装部1及环绕部2是由所述塑料材料a及分散于塑料材料a中的色粉材料b所形成。
其中，所述包装容器100具有一特殊光学特性，即所述包装容器100通过一分光光度计(spectrophotometer)，在介于380纳米至780纳米之间的一波长测量范围下，具有不小于20％的一光阻挡率(light blocking rate)。
基于上述特殊的光学特性，所述包装容器100能有缤纷的色彩，并且能对特定波长的光线产生阻挡能力。
更具体而言，所述包装容器的所述光阻挡率由以下公式定义：
Figure PCTCN2022094434-appb-000003
其中，T(color)为具有所述色粉材料的所述包装容器的一平均光穿透率，并且T(colorless)为不具有所述色粉材料的一无色包装容器的一平均光穿透率。光穿透率％＝(I/I0)*100％，I0为入射光强度，I为出射光强度。
需说明的是，在本文中述及的“平均光穿透率(average light transmittance)”是指包装容器通过分光光度计在介于380纳米至780纳米之间的波长测量范围下，针对不同波长(如：380纳米、400纳米…至780纳米)所测得的光穿透率曲线(如图4)，并且将光穿透率曲线取算术平均数而获得。
另外，上述不具有色粉材料的无色包装容器是指一般无色透明的包装容器，其具有较高的光穿透率，且在颜色变化上显得枯燥乏味。也就是说，本文中所提及的光阻挡率是以 具有色粉材料的颜色包装容器与不具有色粉材料的无色包装容器进行比较及计算所获得的结果。
在本发明的一些实施方式中，具有所述色粉材料的包装容器的平均光穿透率T(color)是介于5％至50％之间、且优选是介于5％至35％之间。不具有所述色粉材料的无色包装容器的平均光穿透率T(colorless)是介于40％至70％之间、且优选是介于40％至60％之间。再者，所述光阻挡率不小于20％、且优选是介于20％至85％之间。
借此，本发明实施例中具有所述色粉材料的包装容器能在具有一定透明度的条件下，对保存于其内的活性成分产生保护作用。值得一提，本发明实施例的包装容器仍保持一定的透明度，目的是为了让用户或检测仪器能观看或检测保存于其内的隐形眼镜及缓冲溶液。
若光阻挡率及T(color)的数值范围超出了上述的数值范围，则隐形眼镜的包装容器将可能无法对保存于其内的活性成分产生保护作用(如光阻挡率小于20％)，或者，保存于包装容器内的隐形眼镜及缓冲溶液将可能无法被用户或检测仪器观察(如T(color)小于5％)。
所述包装容器的容器厚度t会影响到光阻挡率(如图2)。
在本发明的一些实施方式中，所述包装容器的一容器厚度t介于0.4毫米(millimeter，mm)至1.2毫米之间。优选地，所述包装容器的一容器厚度t介于0.6毫米至1.0毫米之间。
若包装容器的容器厚度太薄(如小于0.4毫米)，则光阻挡率可能会太低，以至于无法对活性成分产生保护效果。另外，包装容器可能会因为厚度太薄，而容易在受挤压时发生形变，从而影响了包装容器的外观。
若包装容器的容器厚度太厚(如大于1.2毫米)，则光阻挡率可能会太高，以至于保存于包装容器内的隐形眼镜及缓冲溶液无法被用户或检测仪器观察。
在所述塑料材料的材料种类方面，所述塑料材料是选自由：聚乙烯(polyethylene，PE)、聚丙烯(polypropylene，PP)、聚苯乙烯(plystyrene，PS)及聚甲基丙烯酸甲酯(poly(methyl methacrylate)，PMMA)，所组成的材料群组中的至少其中之一，但本发明不受限于此。所述塑料材料的材料种类只要是能用于形成包装容器、具透光性、并能用于保存隐形眼镜及缓冲溶液，即符合本发明的保护精神，而属于本发明的保护范围。
在所述塑料材料的含量范围方面，所述塑料材料于包装容器中的一质量百分浓度不小于80wt％、且优选不小于90wt％。也就是说，所述塑料材料为形成包装容器的主要基质 材料。
在所述色粉材料的材料种类方面，所述色粉材料是选自由：并咪唑酮型颜料(Benzimidazolone)、吡咯并吡咯二酮型颜料(Diketopyrrolopyrrole)、异吲哚啉酮系颜料(Isoindolinone)、缩和型偶氮型颜料(Azo)、双偶氮型颜料(Disazo)、喹吖啶酮型颜料(Quinacridone)、酞菁铜型颜料(Cu-Phthalocyanine)、卤化酞菁铜型颜料(Cu-Phthalocyanine(Halogenated))、蒽醌型颜料(Anthraquinone)，所组成的材料群组中的至少其中之一，但本发明不受限于此。所述色粉材料的材料种类只要是能用来使包装容器具有颜色，并提升光阻挡率，即符合本发明的保护精神，而属于本发明的保护范围。
所述色粉材料的含量范围会影响到光阻挡率以及T(color)。在本发明的一些实施方式中，所述色粉材料于所述包装容器中的一质量百分浓度不小于50ppm、且不大于0.3wt％。若所述色粉材料的含量范围太低(如低于50ppm)，则光阻挡率会太低，以至于无法对活性成分产生保护效果。
反之，若所述色粉材料的含量范围太高(如高于0.3wt％)，则光阻挡率会太高(或T(color)会太低)，以至于保存于包装容器内的隐形眼镜及缓冲溶液无法被用户或检测仪器观察。
在本发明的一些实施方式中，所述色粉材料的颜色为黄色、橘色、红色、紫红色、紫色、粉红色、蓝色及绿色的至少其中之一，但本发明不受限于此。
所述色粉材料可以单一颜色添加至塑料材料中，或者，也可以两种以上的颜色添加至塑料材料中，以使包装容器具有不同的颜色，如黄色、橘色、红色、蓝色、或黑色…等。
在本发明的一些实施方式中，所述包装容器的颜色为黄色、橘色、红色、蓝色、或黑色，所述包装容器的一容器厚度介于0.6毫米至1.0毫米，并且所述包装容器通过所述分光光度计在介于380纳米至780纳米之间的所述波长测量范围下，具有介于20％至85％之间的一光阻挡率。
更具体而言，如图4所示，图4显示具有不同颜色的包装容器，通过所述分光光度计在介于380纳米至780纳米之间的所述波长测量范围下，所测量出的光穿透率曲线(％T)。下表1则是依据图4中具有不同颜色的包装容器的光穿透率曲线分别计算出不同的平均光穿透率及光阻挡率。
