附图说明
图1是本实用新型一种实施例的结构外侧视角示意图；
图2是本实用新型图1实施例的结构内侧视角示意图。
具体实施方式
下面结合附图和实施例，对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型，但不用来限制本实用新型的范围。
在本实用新型的描述中，应当理解的是，除非另有明确的规定和限定，本实用新型中采用术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本实用新型中的具体含义。
本实用新型的描述中，还需要理解的是，术语“上”、“下”、“左”、“右”、“前”、“后”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的机或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
参考图1和2，本实用新型实施例的一种防伪盖，包括第一色塑料 注塑的外壳1、第二色塑料注塑的内壳2和第三色塑料注塑的内圈3，所述外壳1的外侧表面上设置有第二色塑料或双色塑料、多色塑料注塑的标识部4，所述标识部4嵌合地注塑于所述外壳1中，所述内壳2注塑于所述外壳1的内侧侧壁上，所述内壳2上设置有连接部21，所述内圈3注塑于所述外壳1的内侧底面上，因此外壳1通过标识部4便能很好地形成防伪标记，特别是第二色塑料注塑的标识部4非常牢固地与外壳1构成一体，并非在注塑定型后将两部件压合的存有相互作用力的连接结构，因此标识部4耐久度非常好，而且能够按需设置在外壳1的外侧面任意位置，优选地标识部4包括位于外壳1的外侧壁面和外侧顶面的至少两种注塑结构；而且内壳2通过连接部21可设置为卡勾、卡块等结构以让防伪盖在使用中方便安装，内圈3则可以在防伪盖用于盖合到相应容器的开口时进行阻隔、密封作用，内壳2和内圈3均为与外壳1同时成型，从而确保有很好的整体结构性。
参考图1，示例性的，所述标识部4位于所述外壳1的外侧侧壁，所述标识部4为所述内壳2的第二色塑料从所述外壳1的内侧侧壁穿过并延伸至所述外壳1的外侧侧壁上一次注塑成型，因此在注塑过程中高效地将内壳2和标识部4同时注塑完成，既缩短工时，又能降低生产成本，标识部4还具有双色塑料或多色塑料注塑时，可在内壳2一次注塑的工艺上再于标识部4的外侧表面以其它色塑料注塑成型。
参考图1，示例性的，所述标识部4位于所述外壳1的外侧顶面，所述标识部4从所述外壳1的内侧底面穿过并延伸至所述外壳1的外侧顶面，外壳1的外侧顶面上的标识部4与外壳1的外侧壁面的标识部4均能在内壳2通过第二色注塑时同时在外壳1内侧进行加工，能够非常高效地实现注塑工序。
参考图1或2，示例性的，所述外壳1于外侧侧壁上设置有防滑凸起11，通过防滑凸起11能够提升外壳1表面的握持摩擦力，从而更方便操作，防滑凸起11可优选设置为数个平行并绕外壳1中心轴旋转分布的凸条。
参考图2，示例性的，所述连接部21为所述内壳2于表面上凸起的螺纹，所述连接部21即为防伪盖的内螺纹，方便通过螺纹连接的方式盖合到匹配的箱体或瓶体上进行应用，同时配合内圈3的密封性也很好。
参考图1和2，示例性的，所述外壳1、所述内壳2和所述标识部4为硬胶，所述内圈3为软胶，因此防伪盖通过外壳1、内壳2和标识部4构成坚固的受力结构，配合内圈3进行抵接密封，耐用性和密封性非常好。
参考图1和2，示例性的，所述外壳1、所述内壳2和所述标识部4为PP或ABS，所述内圈3为塑硅，优选地外壳1、内壳2和标识部4可同时选用PP或ABS这两种硬胶材质来配合内圈3的塑硅软胶材质进行三色注塑，确保防伪盖的使用性能同时又耐用。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本实用新型的保护范围。
