Abstract

一种用于固定气密容器盖衬垫的结构包括形成在盖子下表面的环形槽；衬垫，包括向上地以向外方向膨胀的紧密接触表面部分，以便基于与容器主体内壁表面的紧密接触密封空隙，和固定表面部分，其水平地朝紧密接触表面部分内侧方向延伸；多个形成在衬垫固定表面部分上的狭缝按规则的间隔距离排列成弧形，各具有与环形凹槽同样的宽度；和突出的并具有与衬垫的狭缝同样截面的衬垫固定件。

Description

固定气密容器盖衬垫的结构
技术领域
本发明涉及一种用于固定气密容器盖衬垫的结构，它能够有效地利用衬垫密封容器内部。
背景技术
如图6所示，当在一般用来储存食品的容器21中形成圆形的容器主体22和盖子23时，与盖子23接合的圆形衬垫24紧密地接触容器主体22的内壁表面25，从而密封容器内部。
不过，在传统技术中当衬垫24固定和接合时，在衬垫24内端形成的固定端26简单地插入形成在从盖子23下表面突出的壁形件之间的圆形固定槽27中。在上述构造中，当对/从容器主体22盖上或开启盖子23时，在衬垫上发生某种推压现象，使固定端26从圆形固定槽27中脱出。因此，产品的可靠性降低。
此外，如果采用传统的衬垫24，当关闭容器盖子23时，衬垫24受到压力并且变形，使容器主体22内壁表面25强烈地受压而密封。
在容器主体内侧和外侧由于开放形成在盖子23上的空气流动阀29而相通后，当盖子23从容器主体22分离时，用户感觉到太紧。当开启盖子时发生爆裂噪声，使盖子开启人感觉很坏。
发明概要
相应地，本发明目的是提供一种用于固定气密容器盖衬垫的结构，能够克服在传统工艺中遇到的问题。
本发明另一目的是提供一种用于固定气密容器盖衬垫的结构，能够有效地防止当盖子对/从容器主体盖上或开启时衬垫容易地脱出。
为获得以上目标，在密封容器盖子和空气流通阀中，其中盖子包括接合在盖子下表面上的衬垫以便紧密地接合和密封容器主体的内表面上边，而空气阀设计用来当盖子关闭时隔断内边和外边之间的连通并且当开启盖子时防止容器主体内的真空，设置用于固定气密容器盖衬垫的结构，其包括形成在盖子下表面的环形槽；衬垫，包括向上地以向外方向膨胀的紧密接触表面部分，以便基于与容器主体内壁表面的紧密接触密封空隙，和固定表面部分，其水平地朝紧密接触表面部分内侧方向延伸；多个形成在衬垫固定表面部分上的狭缝按规则的间隔距离排列成弧形，各具有与环形槽同样的宽度；和突出的并具有与衬垫的狭缝同样截面的衬垫固定件，其包括多个固定突出部分通过狭缝和插入环形槽，其中衬垫固定件固定地压迫衬垫的固定表面部分。
附图简要说明
本发明将通过参考附图更好理解，这些附图仅作为说明，而因此不对本发明提出限制，其中：
图1为阐明按照本发明的气密容器盖的衬垫接合结构图；
图2为阐明按照本发明衬垫的底视图；
图3为阐明按照本发明衬垫主要部分的剖面图；
图4为阐明衬垫固定件的平面图；
图5为阐明按照本发明的衬垫固定件的正视剖面图；
图6为阐明传统工艺视图。
具体的实施方式
本发明较佳实施例将参照附图描述。
图1为阐明按照本发明的气密容器盖的衬垫接合结构图，图2为阐明按照本发明衬垫的底视图，而图3为阐明按照本发明衬垫主要部分的剖面图。
此外，图4为阐明衬垫固定件的平面图，而图5为阐明按照本发明的衬垫固定件的正视剖面图。
从密封的容器盖1下表面2突出两垂直壁3和4，其中两垂直壁为同心圆。环形接合槽5形成在两垂直壁3和4之间。
衬垫6放置在两垂直壁3和4的下边。衬垫由几乎水平的固定表面部分7，和紧密接触表面部分10形成，部分10以某种倾斜程度从内壁表面9上边升起并且紧密地与容器主体8内壁表面9上边接触从而密封空隙。在紧密接触表面部分10上，以类似于高尔夫球表面的浮雕形状形成多个小型凹槽11。这里，小型凹槽11可以用腐蚀或注射模塑方法形成。
多个弧形狭缝12，各具有对应于接合槽5宽度的某种宽度，在水平固定表面部分7上沿圆弧形部分按照一定互相之间的间隔形成。
衬垫6由衬垫固定件13固定。多个固定突出部分14垂直地从衬垫固定件13突出，其中各固定突出部分具有与弧形孔12同样尺寸及某种截面形状。固定突出部分14穿过衬垫6的弧形狭缝12并且紧密地插入形成在垂直壁3及4之间的环形接合槽5。在以上构造中，即使当对应于衬垫6外部的固定表面部分10被拉动，衬垫6被衬垫固定件13的固定突出部分14所抓住而稳定地支撑，使衬垫不能从盖子1脱出。
在本发明中，密封容器盖1覆盖容器主体8，并且空气流通阀15被关闭从而隔断空气进入。衬垫6的紧密接触表面部分10被容器主体8的内壁表面9所压迫从而密封空隙。在以上状态下，即使用户试图开启盖子1，由于在容器主体内部形成一定的真空，不能容易地开启盖子。
因此，当用户需要开启盖子5时，必需提起和开启空气流通阀15。外部空气通过开放的空气流通阀15输入容器主体8，使容器内部不再形成真空从而使盖子更容易获得脱开。
在本发明中，小型凹槽11通过腐蚀方法形成在衬垫6的紧密接触表面部分10，使对于内壁表面9的接触面积减少，从而盖子1能够容易地开启。当释放对于内壁表面9的紧密接触状态时，由于充满的空气而使凹槽11容易地从紧密接合中释放，并且防止爆裂噪声。在本发明中，所描述的为圆形容器，但诸如矩形容器等某种形状的容器也可以适用。
如以上描述，在衬垫上形成多个狭缝。衬垫固定件的固定突出部分穿过狭缝并且紧密地插入形成在盖子下表面的环形槽从而压紧并固定衬垫。在以上构造中，即使当衬垫被拉动时衬垫也不分离，除非衬垫固定件被分开。因此，在本发明中，有可能防止由于当盖子接合时衬垫脱开或活动而引起的不良的盖子接合状态，从而改进产品的可靠性。
此外，在衬垫的紧密接触表面部分上形成多个类似高尔夫球表面的狭缝，当分开盖子时使衬垫容易地从容器主体内壁表面分离，从而获得更容易的开启操作并且减少爆裂噪声，这是在传统工艺中当从容器主体开启盖子时通常发生的。
由于本发明可以在多种形式中实施而不偏离其精神或基本特性，应该理解上述例子并不被以上描述中任何细节所限制，除非另有规定，但是应该广义地理解为在所附权利要求中定义的精神和范围以内，并因此所有落入权利要求所满足的情况和限度的变化和变型、或者相当于这样满足和限度的事物将被所附权利要求所包含。
