Description

密封盖 技术领域 本发明涉及一种密封盖， 更进一步说， 尤其指一种结构筒单、 能应用于 各种形状与材料的容器， 具有可抽真空功能的密封盖结构设计。 背景技术 已知的应用于各种容器开口形状的密封盖结构， 如图 1所示 (以圆形开口 容器为例）， 其主要是一盖体 20盖于一容器 10开口处的顶边 11 , 该盖体 20与 该顶边 11接触处设有一环状的凹槽 23，以及一密封垫 24设置于该凹槽 23内， 使得该容器 10的顶边 11可套入该凹槽 23内， 且该顶边 11与该密封垫 24接 触。 另外， 容器 10在邻近该顶边 11外侧设有多个凸出的固定部 12 , 而该盖 体 20设有相对应的紧扣翼 21 , 这些紧扣翼 21铰接于盖体 20外围， 使这些紧 扣翼 21相对于该盖体 20转动， 且这些紧扣翼 21上各设有至少一穿孔 22与这 些固定部 12相对应。 当盖体 20置于容器 10的开口处时， 使用者用手指压下 这些紧扣翼 21， 将这些紧扣翼 21压向容器 10的固定部 12后， 这些固定部 12 将分别穿越这些穿孔 22而紧扣， 使该盖体 20紧盖于该容器 10的开口， 通过 该顶边 11紧压该密封垫 24于该凹槽 23内， 使该容器 10内部空间与外界隔绝 形成密封状态。 但是， 这些紧扣翼 21的设计容易因为重复紧扣及打开转动的次数太多， 而造成铰接处的撕裂或断裂。 如果增加铰接处的厚度， 虽然可以减少撕裂或断 裂的风险， 但铰接处如果太厚， 这些紧扣翼 21 的紧扣及打开的动作将会变得 吃力， 不易使用者单手操作。 另外， 这些固定部 12 的设计也无法保证容器 10开口的完整性， 所以在容器 10开口为圆形时， 这些紧扣翼 21的穿孔 22位 置必须与这些固定部 12对准， 才可以使这些紧扣翼 21紧扣于这些固定部 12， 操作上相当不便。 为解决上述的问题， 另一种盖体 40的结构如图 2所示， 以圆形开口容器 为例， 该结构也是应用在一容器 30, 该容器 30开口处具有平滑的顶边 31， 该 盖体 40设置于该顶边 31上方。 该盖体 40下方设有一凸环部 43 , 使盖体 40 下表面及该凸环部 43外侧形成一环绕该凸环部 43的顶接部 41 , 且该顶接部 41某一处可向外延伸形成一扳部 42。 其中该凸环部 43外径略小于该容器 30 的开口内径， 一凹槽 44环绕该凸环部 43外侧壁， 一片状式密封圈 45部分外 露地环绕插固于该凹槽 44内， 且该密封圈 45上某一处中央设有一透气孔 46。 当该盖体 40盖置于该容器 30的顶边 31时， 该凸环部 43被塞入该容器 30开口内侧， 通过该透气孔 46排出该容器 30内部的空气， 使该凸环部 43与 该密封圏 45可被挤压塞入， 直到该顶接部 41与顶边 31相抵， 且外露的密封 圈 45被紧迫挤压于该凸环部 43与容器 30的内壁之间， 使该容器 30的内部空 间与外界隔绝形成密封的状态。 而通过该扳部 42, 使用者可轻易向上扳动该盖 体 40脱离容器 30的开口处。 但是， 片状式的密封圈 45设计虽然使容器 30的开口保留原有的开口形 状， 但用来排气的透气孔 46却也使得容器 30的密封性效果不佳。 另外， 前面 所述已知的密封盖结构也都只具有密封功能， 而无法对容器内部进行抽真空的 功能。 发明内容 本发明的目的在于提供一种密封盖， 其应用的容器外无需设有固定凸出 部，且密封组件上也不需要有透气孔，可应用于对于任何形状开口的容器密封， 且密封功能更完整。 且容器的开口形状也可以保证原有的完整性， 使用上无对 准的问题， 操作更方便。 本发明的另一目的在于提供一种具可抽真空功能的密封盖，通过抽气装置 即可将容器内的空气抽出， 使容器内部形成真空， 且通过二个密封圈的设计， 可使密封盖的密封功能更完整， 且密封盖可保持容器内部的真空度， 使收纳在 容器内的物品延长其保存期限。 本发明是一种应用于密封一容器的一盖体，其特征在于该盖体包括： 一凸 环部， 该凸环部设置于该盖体下方， 用以塞入该容器的开口， 且该凸环部外围 形成一顶接部； 一密 ϋ环圈， 该密去于环圈环绕地固地设置于该凸环部外侧， 其 中该密封环圈上具有二片状向外延伸的一第一密封圈与一第二密封圈， 该第一 密封圈固地设置于该顶接部表面， 而该第二密封圈临近于该凸环部顶端处； 一 套孔设置于该盖体表面， 且该套孔周边至少设置有一气孔； 以及一透气伞阀装 设置于该套孔。 其中， 该凸环部外径略小于该容器的开口， 使该凸环部被塞入该开口后， 该第二密封圈被挤压于该凸环部与该容器内壁之间， 使该容器内部空间与外界 隔绝形成密封的状态， 且该第一密封圈被挤压于该顶接部与该容器开口处的顶 边之间。 其中，该顶接部环绕该凸环部进一步可设有一凹槽，使该第一密封圈可嵌 固于内， 由此可使该顶接部与该第一密封圈的表面形成一平面。 其中， 该透气伞阀包括一膜片， 该膜片覆盖于前述气孔上方， 一按压部， 该按压部设置于该膜片上方， 以及一挡卡部， 该挡卡部设置于该膜片下方， 用 以插套该透气伞阀固定于该套孔。 其中， 通过该透气伞阀的可泄气功能， 使盖体易于盖住该容器开口， 且通 过抽气装置即可通过该透气伞阀将容器内的空气抽出， 使容器内部形成真空， 且通过该第一密封圏的加强密封， 可忽略第二密封圈的变形因素， 使该盖体可 保持容器内部的真空。 其中，该顶接部一处延伸扩大形成一板部，通过该扳部使用者可轻易向上 的扳动该盖体脱离该容器的开口。 其中，该按压部与该膜片的交接处向下凹设一折缘部，使得该膜片易于折 曲而掀逾脱离各气孔上方。 其中， 该盖体的顶盖表面可向下凹设一凹埠， 使该套孔是位于该凹端口， 方便抽气装置定位在该凹埠上进行抽气的动作。 通过上述技术，本发明至少有以下优点,本发明通过二个片状密封圈的双 层密封结构， 所以容器外部周缘无需具有固定凸出部， 且开口形状也不再受限 制， 使用上无扣合的对准问题， 操作将更方便。 且通过该透气伞阀的可泄气功 能， 密封圈上不需要有透气孔， 所以应用上具有良好的密封功能， 而且通过透 气伞阀的设置 , 本发明通过抽气装置即可将容器内的空气抽出以形成真空。 另外，对于抽真空后第二密封圈可能因为该凸环部与容器内壁之间的变形 挤压而会有泄气的可能， 所以通过被抽真空后盖体与容器更紧密结合挤压的原 理， 第一密封圏发挥其密封的功能。 所以该凸环部与容器内壁间的空隙， 以及 该第二密封圏整体厚度的精密度都将可以被忽略， 而不会有抽真空后该第二密 封圈会泄气的情况， 增加制造上的简易性。 附图说明 图 1 , 是已知密封盖与容器的分解示意图。 图 2, 是另一种已知密封盖与容器的分解示意图。
