Description

具有帽沿衬垫的容器盖
技术领域
本发明涉及密封容器，具体涉及一种容器的密封盖。
背景技术
现在使用的储存食品的容器，为了达到密封的效果，需要在容器盖外侧周围安装凸出的衬垫，当盖上容器的盖时，容器盖插入容器主体的内部，依靠容器盖向下的压力，顺着容器主体的内壁表面，压挤在容器盖周围外侧露出的衬垫，依靠容器主体内压力的变化，使空气顺着衬垫与容器主体内壁表面的缝隙排出。
同时为了使所述衬垫固定在容器盖上，目前一般采用将容器盖的上部和下部之间分离组装，在两者之间固定衬垫的方法。
综上所述，现有的密封盒盒盖结构以及衬垫的组装方式存在的缺点是无法实现精密的组装，由于增加压力会使衬垫的形状改变，造成衬垫脱离；并且用这样的结合方式组合容器盖时，产生的空隙会夹进异物质，留下不卫生的隐患。
发明内容
本发明的一个目的是提供一种具有帽沿衬垫的容器盖。
本发明的目的通过以下技术方案来予以实现：
本发明提供一种具有帽沿衬垫的容器盖，包括上侧表面10、上侧表面10下侧形成的支撑臂12、与支撑臂12上侧形成一体的凸出部分14和衬垫20；所述上侧表面10设置有空气流通阀11；所述衬垫20包括与所述支撑臂12的侧面紧密结合的固定端21和由所述固定端21延伸形成的帽沿22。
作为一个备选方案，所述支撑臂12的上侧与凸出部分14可以一次注塑形成一体，在二者结合处附近的下侧形成支撑臂12，紧贴支撑臂12的侧面插入注塑形成固定端21；
作为另外一个方案，所述支撑臂12的上侧与凸出部分14之间设置有贯穿容器盖上侧的狭缝13，衬垫20的固定端21通过狭缝13使支撑臂12上侧与凸出部分14形成一体。
所述凸出部分14设置有凸出沿15。
所述凸出部分14上表面还可以设有凹槽16。
所述衬垫20的固定端21通过狭缝13填充于凹槽16并使支撑臂12上侧与凸出部分14形成一体。
所述衬垫20采用硅橡胶材料或者类似于硅橡胶的材料。
所述空气流通阀11采用杠杆扣合，利用现有技术的采用杠杆原理开合的结构作为空气流通阀。在空气流通阀11开合使空气出入的空气通路上也依靠双重注塑的方式，形成衬垫，使之与空气流通阀的轴紧密粘贴。
本发明同时提供一种使用所述具有帽沿衬垫容器盖的容器，可选用合成树脂材质，包括所述的容器盖和容器主体30，当所述具有帽沿衬垫的容器盖使用于相应的容器主体时，凸出沿15和容器主体30的上沿31紧密接触。所述容器主体30的上沿31周长几乎和容器盖10的凸出沿15周长一致，使容器主体的上沿31的下端形成的突出部分32处于衬垫20的帽沿22的前端位置。
在本发明方案中，优选有很强弹力性和伸缩性的硅橡胶塑料材料制成的衬垫，紧贴于所述衬垫容器盖上的支撑臂的侧面，形成固定端，所述的固定端和延伸出来的帽沿形成一体，这样的固定端和帽沿依靠双重注塑，不需要另外的组装过程，一次成型。
采用所述的插入注塑时，在支撑臂12的上侧形成狭缝13，固定端21通过容器盖的狭缝，填充于凹槽16处，在容器盖的上侧面还可以形成装饰面，可以实现紧密且多样的设计。
本发明的有益效果是：
不需要采用其它多余的结合方法也可以在容器盖上实现有帽沿的衬垫，这样结构的衬垫紧密固定在容器盖的支撑臂上，形成固定面，支撑臂和紧贴于支撑臂的固定端延伸形成衬垫的帽沿，配合使用容器盖上侧表面的空气流通阀，由于压力使衬垫和容器主体的内壁表面紧密接触，实现真空密封。

具体实施方式
下面结合附图和具体实施例来进一步详细说明本发明。
实施例1
如附图3所示，本发明提供一种具有帽沿衬垫的容器盖，包括上侧表面10、上侧表面10下侧形成的支撑臂12、与支撑臂12上侧形成一体的凸出部分14和衬垫20；所述上侧表面10设置有空气流通阀11；所述衬垫20包括与所述支撑臂12的侧面紧密结合的固定端21和由所述固定端21延伸出来的帽沿22。
本实施例中上侧表面10、支撑臂12、与支撑臂12上侧形成一体的凸出部分14可以一次注塑成型得到，与所述支撑臂12的侧面紧密结合的固定端21和由所述固定端21延伸出来的帽沿22构成的衬垫20通过注塑紧密的粘贴于支撑臂12的侧面。制造衬垫20所使用的材料采用一种硅橡胶材料，也可以使用和硅橡胶具有同样特性的其它材质。
所述空气流通阀11采用杠杆扣合，利用现有技术的采用杠杆原理开合的结构作为空气流通阀。在空气流通阀11开合使空气出入的空气通路上也依靠双重注塑的方式，形成衬垫，使之与空气流通阀的轴紧密粘贴。
附图5和附图6分别给出了本发明具有帽沿衬垫的容器盖应用于相应的容器主体30上的外观分离和组装时的示意图。
实施例2
如附图1、附图2和附图4所示，本发明提供一种具有帽沿衬垫的容器盖，包括上侧表面10、上侧表面10下侧形成的支撑臂12、与支撑臂12上侧形成一体的凸出部分14和衬垫20；所述上侧表面10设置有空气流通阀11；所述衬垫20包括与所述支撑臂12的侧面紧密结合的固定端21和由所述固定端21延伸出来的帽沿22。
制造衬垫所使用的材料采用一种硅橡胶材料，也可以使用和硅橡胶材料具有同样特性的其它材质。
在本实施例中，支撑臂12的上侧与凸出部分14之间设置有贯穿容器盖上侧的狭缝13，衬垫20的固定端21通过狭缝13使支撑臂12上侧与凸出部分14形成一体。
所述凸出部分14设置有凸出沿15，还可以设有凹槽16。
所述衬垫20的固定端21通过狭缝13部分或全部填充于凹槽16并使支撑臂12上侧与凸出部分14形成一体。
所述的容器盖与相应的容器主体配合使用时，凸出部分14所形成的凸出沿15和容器主体30的上沿31紧密接触，所述容器主体30的上沿31周长几乎和容器盖10的凸出沿15周长一致，使容器主体的上沿31的下端形成的突出部分32处于衬垫20的帽沿22的前端位置。
所以，这样衬垫20在容器盖的下侧周围突出的帽沿22依靠固定端21和容器盖形成一体，使容器盖和容器主体紧密接触且不容易分离，而且衬垫20的固定端21贯穿狭缝，部分或全部填充于在容器盖的上表面的凹槽16，更好的固定了衬垫，即使有其他外力，固定端也可以很好的坚固衬垫使之不会脱落。
