Easy to use leak-proof cover. Specifically, it is convenient to open and retrieve materials. Closed and sealed leak-proof cover includes inner and outer cover. The inner cover is covered with internal threads and the outer half-threaded groove. The upper end of the threaded groove is the opening limit, the lower end is the opening limit, and the upper end of the outer threaded groove is next to the opening limit. The outer thread groove naturally overflows the top surface of the inner seal and forms a notch, that is, it becomes the entrance of the outer cover. The inner half thread of the outer cover connects the top root, the upper end to the flat end of the thread, the lower end to the flat end of the thread. The thread is attached to the inner wall of the outer cover and has an angle of more than 15 degrees. Like the inner cover, a pair of holes of different sizes and shapes are opened on the top surface. The large hole is the material intake and the small hole is the air intake; the outer cover can be used as an easy-to-use leak-proof cover by screwing the entrance of the outer cover and the inner seal, which can effectively promote the reuse of drinking goods filling instruments, reduce environmental pollution and resource waste, and effectively control folk liquor under the supervision of relevant units. The counterfeiting of state-owned food is spread through illegal vendors taking advantage of the gap that is difficult for the government to supervise.

易用防漏盖
易用防漏盖,具体来说就是开盖和关盖一样均不离容器口的盖,特别适用于饮、食用品和药丸的盛装容器盖。
技术介绍
瓶盖,作为一种贮物容器的顶盖,即要方便使用时容易取到容器里的物质,又要确保不用时关闭顶盖后不会遗漏,所以,从一种简单的内螺纹平顶盖,经过许多设计优化,衍生了若干种情趣各一的盖子。其中不泛有结构简单,功能也简单的;结构复杂、功能较全面的形形色色的盖子。这些盖子基本都有一个特点是,使用时基本是容器与盖必须分离,或者用针刺穿瓶盖吸取。这些缺陷在于:一是取物量不容易把控;二是瓶盖容易脱落丢失;三是容器二次使用少且不合卫生规范,资源浪费较大。
技术实现思路
为了解决瓶盖在使用中的上述缺陷,本专利技术提供一种易用防漏盖。采用内封加外盖的组合方式组合为成套盖,在内封和外盖上均开设大小不同两孔。内封固定封盖容器口,与容器紧固衔接成为一体,不能轻易转动旋开;外盖套盖在内封外层,使用时逆时针拧动外盖,使外盖进气孔和取物口与内封进气孔和取物口开合到适用状态,利于使用者按自己意愿取物,直到外盖的螺纹平尾触碰到内封的开盖限位时,外盖即打开停止,此时的两进气孔和取物品均为开满状态,即完全打开取物也不会与内封分离,也就是取物时盖与容器始终不会脱开,容器中内存物顺利从取物孔倒出;封存时顺时针拧动外盖,直到外盖的螺纹平头触碰到内封的关盖限位点,整个容器处于密闭封存状态。使用中的各打开状态和全密封状态见图4至图7。本专利技术解决其技术问题所采用的技术方案是:所述易用防漏盖,包括内封和外盖两层组合,其中内封基本结构如图1,内封里面布满内螺纹,外面是半螺纹槽,螺纹槽上端是开盖限位, ...

1.所述易用防漏盖,包括内封和外盖在内的密封结构套件,其特征在于:内封或直接与盛装容器塑造,或内设全螺纹与容器配合旋装,固定封盖容器口,与容器紧固衔接成为一体,外面是半螺纹槽,螺纹槽上端是开盖限位,下端是关盖限位,外螺纹槽上端的开盖限位旁边,外螺纹槽自然溢出内封顶面,形成缺口,即成为外盖旋入口;外盖里面半螺纹接顶根部,上端至螺纹平尾,下端至螺纹平头,螺纹下设置便于压装时螺纹回弹忍让的开口夹角,外盖与内封一样,顶面均开设一对大小不同的孔,大孔为取物口,小孔为进气孔;外盖通过下压或内封的旋盖入口旋装,与内封成为易用防漏盖整体,不能轻易分离。
