Description

真空单向排气阀
技术领域 本发明涉及一种排气阀, 尤其涉及一种应用在真空袋, 以确保内容物鲜 度的单向排气阀。 背景技术 已知应用于保存咖啡豆的咖啡袋, 如中国台湾专利公告号第 M325290 号, 该咖啡袋具有一呼气结构, 包含有: 一圆形的座体, 该座体的一面是贴 合面, 该贴合面贴合于该咖啡袋的内面, 且该贴合面中央凹设一透气空间, 供导通排气, 该透气空间内设一限制环, 该透气空间于该限制环所圈设的壁 面设有至少一个透气孔, 且该限制环内缘径向具有两个向座体中心延伸的卡 部, 一圆形橡胶材料的片体, 该片体组设在壁面与该卡部之间, 以压抵该透 气孔 。 因此, 在常态与压缩袋子 ^非气时, 该贴合面结合于咖啡袋的内面, 且通 过各卡部卡止该片体, 使该片体挡住各透气孔, 防止袋外的空气进入咖啡袋 内。 当取用内容物封口后, 将咖啡袋的气体挤压至呼气结构, 使多余空气由 透气孔至片体, 该片体受压会向外凸出, 空气可由等距设置的各卡部的间距 排出, 使咖啡袋内部形成真空, 延长保存时间。 实际上, 该橡胶材料的片体表面会涂有一硅胶油, 以使片体紧密的贴覆 于该壁面, 而能封设各透气孔, 但是保存于咖啡袋内的咖啡会有粉末, 随着 袋内空气的压挤至透气孔, 会沾黏在片体内面, 导致该片体不能紧密地将各 透气孔封住, 且随着时间慢慢松离, 无法达到真空保存的效果。 发明内容 因此, 本发明的主要目的在于提供一种装设于袋体上, 可避免袋体内粉 末状的内容物附着在凸缘表面, 使袋体内部不能长保真空, 影响内容物保存 鲜度的真空单向排气阀。 经由以上可知, 为达到上述目的, 本发明提供一种真空单向排气阀, 用 于组配在一袋体上, 所述真空单向排气阀包含一底盖、 一硅胶片与一上盖, 其中该底盖与该袋体贴固, 该底盖的外壁上环设一凸缘, 该凸缘的内部设有 一通气孔,且该凸缘的外侧环设一限位环, 该限位环的内周形成一容置空间, 该容置空间内设有一气室, 该硅胶片装设于该容置空间内, 并贴覆该凸缘以 封闭该通气孔, 该硅胶片轴向贯设有至少一个气孔, 而该上盖则位于该底盖 的外壁, 其内壁设有凸出的环体, 并使该环体内部形成一腔室, 该上盖的外 壁上设有至少一个排气孔, 该排气孔与该腔室连通, 且该上盖将该硅胶片夹 合并封住。 因此, 在抽离袋体气体时, 该硅胶片中央会向外凸, 脱离该通气孔的开 口, 袋体内气体可由通气孔进入气室, 再由硅胶片的气孔导进于腔室, 最后 由上盖的排气孔放出, 而粉末状的内容物随着气体抽离, 可聚集于气室内, 避免附着在凸缘表面,因此不会影响该硅胶片紧覆该通气孔开口的密贴效果, 可长期确保该袋体内部呈真空, 从而确保保存内容物鲜度。 附图说明 图 1是本发明的立体分解图。 图 2是本发明的立体组合图。 图 3是本发明配合抽气筒抽离气体的动态示意图。 图 4是本发明在袋体气体被抽离呈真空的组合剖视图。 图 5是本发明正装在容器上的剖视图。 图 6是本发明反装在容器上的剖视图。 具体实施方式 有关本发明的详细内容及技术说明,现以实施例来作进一步说明, 但应 了解的是, 该实施例仅用于示例性说明, 而不应被解释为对本发明实施的限 制。 参照图 1至图 3所示, 本发明提供一种真空单向排气阀, 用于组配在一 袋体 a上, 所述真空单向排气阀包含: 一底盖 10、 一硅胶片 20 以及一上盖 其中该底盖 10—侧为一外壁 11 , 该外壁 11的外周面与该袋体 a内面 贴固, 该外壁 11上轴向设有一凸缘 12 , 该凸缘 12内部设有贯通内外的通气 孔 13 , 该凸缘 12外侧环设一限位环 14 , 该限位环 14 内周形成圆形的容置 空间 15 , 该容置空间 15的内周再向内凹设一气室 16, 该气室 16 氐于该凸 缘 12的外端面, 该限位环 14的外周环设一抵制环 17, 该抵制环 17与该限 位环 14之间构成下凹的环槽 18。 而该硅胶片 20为圆形且具柔软弹性度, 并且装设于该容置空间 15内, 其外周正好受该限位环 14的围设定位, 该硅胶片 20贴覆该凸缘 12且将该 通气孔 13 的开口封住, 该硅胶片 20轴向贯设有至少一个气孔 21 , 该气孔 21设置于该硅胶片 20的外周 (本实施例为四个气孔 21 , 并分设于该硅胶片 20的外周)。 该上盖 30则位于该底盖 10的外壁 11上, 该上盖的内壁上设有凸出的 环体 31 , 该环体 31 内部形成一腔室 32 , 该环体 31 内侧朝轴向凸设一密封 环 33 , 该密 ^"环 33围设于该限位环 14的外侧, 该密 ^"环 33与该上盖 30的 环槽 18套接形成密合, 且该上盖 30的外壁上设有至少一个排气孔 34 , 该排 气孔 34与该腔室 32相通, 且为内侧孔径大于外侧孔径的锥形孔, 另外该环 体 31配合该底盖 10的容置空间 15将该硅胶片 20夹合定位; 另外, 该上盖 30外周凸设环形的卡制部 35 , —中空的抽气筒 40与该 上盖 30套接, 该抽气筒 40的内壁设有一凹缘 41 , 该卡制部 35与该凹缘 41 卡合定位, 且该抽气筒 40的邻近该上盖 30的端面受该氏制环 17 ·ί氏接定位。 因此, 本发明应用于容纳有咖啡豆的袋体 a, 使用上可通过该抽气筒 40 与上盖 30套合, 如图 3所示, 抽离袋体 a内的气体, 该硅胶片 20会变形使 中央外凸, 并脱离该底盖 10的通气孔 13开口, 袋体 a内气体可由通气孔 13 进入气室 16 , 再由硅胶片 20的气孔 21进入腔室 32 , 最后由上盖 30的排气 孔 34导出抽离, 而逐渐形成真空, 取下该抽气筒 40 , 该硅胶片 20会因压差 而紧紧附着该通气孔 13开口, 袋体 a内可形成密封状态, 如图 4所示, 以延 长保存袋体 a内收容物的新鲜度。 重要的是, 袋体 a内收容的咖啡豆会残留有粉末状的咖啡粉, 该咖啡粉 随着该抽气筒 40 抽吸气体, 会一起往外抽离, 本发明避免了粉末状的咖啡
3 粉内容物附着在硅胶片 20表面, 造成该硅胶片 20无法长期紧密的封住该通 气孔 13的开口, 且会随着时间而逐渐脱离该通气孔 13的开口, 导致袋体 a 无法维持密封的真空状态, 进而影响内容物的保存鲜度, 因此本发明在底盖 10中央设有该凸缘 12 , 该凸缘 12外周为内凹的气室 16空间, 可收容粉末 状的内容物, 避免沾附在该凸缘 12表面, 而能使该硅胶片 20紧紧封住该通 气孔 13的开口,可确保袋体 a内为真空状态,得以长久保存内容物的新鲜度。 参照图 5所示, 本发明还可以组配在一容器 b上, 该硅胶片 20外侧中 心设一拉钮 22 , 该拉钮 22穿出该上盖 30 , 该抽气筒 40抽离容器 b内的气 体, 容器 b内部会呈真空, 可保存该容器 b内容物的鲜度, 而往外拉起该拉 钮 22 , 则外面空气可进入该容器 b内。 而如图 6所示, 是将本发明反装在该容器 b上, 外面气体可由该通气孔 13灌入该容器 b内, 让容器 b内充满气体, 释放时可利用一凸杆 c穿进该通 气孔 13 , 压抵该硅胶片 20以脱离该凸缘 12 , 就可将容器 b内气体泄出。 通过本发明的设计结构, 无论是抽气或灌气, 含有粉末的气体都能沉积 在该气室 16内, 不会影响该硅胶片 20封住该通气孔 13的气密性。
