Abstract

一体化易拉广口瓶盖，包括一体化成型的下盖、上盖和内塞，所述下盖的横截面呈多边形，在下盖内设有与瓶口配合的内塞，在内塞的塞口设有易撕密封片，在易撕密封片上设有拉环，在下盖与瓶口连接的内壁边设有卡置凸起部，瓶盖采用多边形结构，下盖与瓶口连接的内壁边设有卡置凸起部，保证了下盖与瓶口的点对点精确定位，内塞和下盖与瓶口配合，保证了密封效果，这样在通过拉环作用易撕密封片时，易撕密封片的承受力均衡，不会出现对其撕开时将拉环扯断也未能撕开易撕密封片之窘境。

Description

一体化易拉广口瓶盖 技术领域
本实用新型涉及瓶盖技术领域，具体涉及一种一体化易拉广口瓶盖。
背景技术
瓶盖是密封瓶子用的，具有保持内容物产品密闭性能，还具有防盗开启及安全环保性方面的功能，是瓶容器包装之关键性产品，因此，广泛的应用在瓶装产品上，目前市面上普遍采用圆形瓶口盖，采用多边形的瓶盖设计较少。
发明内容
本实用新型要解决的技术问题是提供一种结构设计合理、密封性能好且易操作的一体化易拉广口瓶盖。
为了解决上述技术问题，包括一体化成型的下盖、上盖和内塞，所述下盖的横截面呈多边形，在下盖内设有与瓶口配合的内塞，在内塞的塞口设有易撕密封片，在易撕密封片上设有拉环，在下盖与瓶口连接的内壁边设有卡置凸起部。
作为本实用新型的进一步改进，所述下盖相邻的内壁边上的卡置凸起部之间设有间隙。
作为本实用新型的进一步改进，在内塞与下盖内壁边之间设有加强筋。
作为本实用新型的进一步改进，所述下盖的横截面为长方形或正方形或菱形。
作为本实用新型的进一步改进，所述下盖的横截面为长方形，且横 截面的长边为圆弧型。
作为本实用新型的进一步改进，所述上盖与下盖之间设有可弯折的连接部。
作为本实用新型的进一步改进，所述下盖的内壁边与内塞之间形成与瓶口配合的凹槽部。
本实用新型的有益效果：瓶盖采用多边形结构，下盖与瓶口连接的内壁边设有卡置凸起部，保证了下盖与瓶口的点对点精确定位，内塞和下盖与瓶口配合，保证了密封效果，这样在通过拉环作用易撕密封片时，易撕密封片的承受力均衡，不会出现对其撕开时将拉环扯断也未能撕开易撕密封片之窘境。
附图说明
下面结合附图和具体实施方式来对本实用新型做进一步详细的说明。
图1为本实用新型的俯视图。
图2为图1的A-A的剖视图。
图3为本实用新型的立体视图。
具体实施方式
图1至图3为本实用新型的实施例：
包括一体化成型的下盖1、上盖2和内塞3，所述上盖2与下盖1之间设有可弯折的连接部4，所述下盖1的横截面呈长方形，且横截面的长边为圆弧型，在下盖1内设有与瓶口配合的内塞3，在内塞3的塞口设有易撕密封片5，在易撕密封片5上设有拉环6，在下盖1与瓶口连接的内壁边设有卡置凸起部7，所述下盖1相邻的内壁边上的卡置凸起部7之间设有间隙，在内塞3与下盖1内壁边之间设有加强筋8，所述下盖1的内 壁边与内塞3之间形成与瓶口配合的凹槽部9。
本实用新型的有益效果：瓶盖采用多边形结构，下盖1与瓶口连接的内壁边设有卡置凸起部7，卡置凸起部7与瓶口外壁面的凹槽相配合，保证了下盖1与瓶口的点对点精确定位，内塞3和下盖1之间的凹槽部9与瓶口配合，保证了密封效果,这样在通过拉环6作用易撕密封片5时，易撕密封片5的承受力均衡，不会出现对其撕开时将拉环6扯断也未能撕开易撕密封片5之窘境。所述下盖1相邻的内壁边上的卡置凸起部7之间设有间隙，这样可以方便下盖1与瓶口之间的拆装。因为在内塞3与下盖1内壁边之间设有加强筋8，加强下盖1与内塞3相连位置稳定性，使易撕密封片5更容易被撕开。
