Description

防泄漏单向阀容器
技术领域 本发明涉及一种容器，尤其是涉及一种排气止回而不泄漏液体和固体的单 说
向阀容器。 书
背景技术 目前， 公知的单向阀容器由密闭容器设置单向阀构成， 单向阀外壳与容器 壁密封连接， 进气口连通容器内部， 排气口连通容器外部。 当容器内部气压高 于外部时， 单向阔开启， 排出容器中的多余气体， 避免容器受压后变形甚至损 坏。 当容器外部压力高于内部时， 单向阀关闭， 阻止空气进入容器中， 导致容 器内容纳物变质、 腐败。 这种容器在容纳咖啡豆这类大颗粒物品时， 既可以排 除咖啡豆产生的二氧化碳， 又可以阻止外部氧气倒灌影响香气和口味， 非常有 效，但是，这种容器的容纳物如果包含液体或小于单向阀进气孔的固体粉末时， 液体和小于单向阀进气孔的固体粉末会从单向阀泄漏， 污损单向阀和容器。
发明内容 为了克服现有的单向阀容器不能防止液体和固体粉末泄漏的不足， 本发 明提供一种单向阀容器， 该单向阀容器不仅能单向排气， 而且能防止容纳物中 的液体和固体粉末通过单向阀，泄漏到容器外部。 本发明解决其技术问题所采用的技术方案是： 在密闭容器上设置有单向 阀， 单向阀外壳与密闭容器壁密封连接， 且单向阀的进气口与容器内部连通， 其特征是： 在单向阀和容纳物之间设置一个气液分离过滤装置， 将单向阀进气 口与容纳物隔离在相邻腔室， 且该气液分离过滤装置包括一防水透气膜， 其同 时接触两相邻腔室部分的面积大于单向阀进气口面积。气液分离过滤装置的防 水透气膜， 密布微小的滤孔， 允许气体的单个分子通过， 而阻隔任何分子成团 的液体和固体微粒。容器中多余的气体可以透过防水透气膜同时接触两相邻腔 室的部分， 及时从容纳物所在腔室进入单向阀进气口所在腔室， 再经单向阀排 放到容器外。而最微小的液滴和固体粉末也会被气液分离过滤装置阻隔在容纳 物所在腔室， 无法进入单向阀进气口所在腔室， 经单向阀排放， 达到防止容纳 物中的液体和固体粉末通过单向阀， 泄漏到容器外部的目的。
密闭容器可以由容器盖和容器腔体密封连接构成， 容器盖上设置有通气 孔， 单向阀设置在容器盖的通气孔位置。
当防水透气膜受压变形过大而贴附在容器盖内璧时，会使防水透气膜的有 效透气面积急剧减小，导致气液分离过滤装置排出气体的能力大大降低且使容 器承受较大的危险内压。 为避免产生此种危险， 可在防水透气膜与容器内壁之 间设置透气支撑单元。 透气支撑单元可以是容器（盖） 内壁或防水透气膜朝向 容器内壁一面不连续的凸紋 （非塑性）， 也可以是另外的刚性或弹性支架， 或 者是密布开放孔洞的弹性体和刚性体， 如海绵、 透气钢等。
本发明的有益效果是， 可以在容器单向排气的同时， 防止任何液体和 /或 粉末状固体内容物泄漏， 污损容器和单向阀， 保持容器的整洁和单向阀的正常 启闭， 延长容纳物的保质时间， 结构简单， 性能可靠。 附图说明

下面将结合附图对本发明作进一步说明。
在图 1、 图 2所示第一个实施例中， 髙分子聚合物构成的容器盖 6和玻璃. 构成的容器腔体 7， 通过相互配合的内螺紋 4和外螺纹 5连接。 容器盖 6上设 置有通气孔 8， 单向阀 1设置在容器盖 6的通气孔位置。 单向阀 1选用纽扣式 咖啡袋单向排气阀， 进气小头朝容器内， 沉入容器盖的通气孔 8中。 超声波悍 接单向阀 1边缘与容器盖 6外壁的接触环面，使单向阀 1外壳与容器盖 6的壁 密封连接， 且单向阀 1的进气口与容器内部连通。气液分离过滤装置由防水透 气膜 2和中部开有通孔的环形密封垫 3构成。防水透气膜 2的形状与密封垫 3、 容器盖 6底部、 容器腔室 7开口外缘相配合。 旋紧容器盖 6时， 防水透气膜 2 与密封垫 3被挤压在容器腔体 7开口与容器盖 6底部之间，将单向阀 1进气口 与容纳物 9隔离在相邻腔室， 构成一个气液分离过滤装置， 且该气液分离过滤 装置包括一防水透气膜 2， 其同时接触两相邻腔室部分的面积大于单向阀 1进 气口面积。 防水透气膜 2选用聚四氟乙烯微孔膜（ePTFE) , 膜上密集分布的微 孔只允许单个的气体分子透过， 进入单向阀 1排放， 而阻隔任何分子成团的最 小液滴和固体， 使其被约束在防水透气膜 2以下的腔室中， 无法到达单向阀 1 进气口， 污损单向阀 1、 泄漏到容器外部。
在图 3、 图 4所示第二个实施例中， 容器盖 6为开有通气孔 8的片状高分 子聚合物， 优选为聚乙烯。 单向阀 1设置在容器盖 6外壁， 选用自粘式方形单 向排气阀， 覆盖在容器盖 6的通气孔位置。 自粘式方形单向排气阀进气侧的外 壳和容器盖通气孔 8周围的外壁粘接在一起， 形成密封连接， 且单向阀 1的进 气口与容器内部连通。容器腔室 7由杯状的高分子聚合物构成，优选为聚乙烯， 开口设置有法兰 11。 防水透气膜 2设置在容器盖 6和容器腔体 7开口的法兰 11之间， 其边缘同时与二者密封连接。连接方式优选为热熔合连接。防水透气 膜 2与容器盖 6形成一薄片状的独立空间，将单向阀 1进气口与容纳物 9隔离 在相邻腔室， 构成气液分离过滤装置。 防水透气膜 2 选用纺粘型烯烃 (Spunbonded Olefin ) , 其同时接触两相邻腔室部分的面积比单向阀 1进气口 大 10倍， 可保证大量气体的及时透过， 而阻隔液体和固体。 防水透气膜 2靠 近容器盖内壁一侧设置有多个均匀分布的球冠状凸纹 10， 凸纹 10通过热压形 成， 可避免防水透气膜 2贴合在容器盖的内壁， 影响气体的整体排放速率。
在图 5所示第三个实施例中，靠近防水透气膜 2的容器盖 6内壁设置有多 个球冠状的凸紋 10，而防水透气膜 2保持为平面，其余的设计与第二个实施例 相同。 在图 6所示第四个实施例中， 防水透气膜 2选用葛尔莱 （gurly) 透气度为 20-60秒的微孔纺粘型聚烯烃 （Spunbonded 01efin)。 本发明要有效地容纳产气 的容纳物 9， 防水透气膜 2的透气率与其有效排气面积的乘积， 应大于容纳物 9的 最大产气速率。 防水透气膜 2透气率越低， 防水透气膜 2的有效排气面积就必须 越大 （瓶口的口径也就必须更大）。 防水透气膜 2与圆圈状的密封垫 3构成气液分 离过滤装置。 密封垫 3内圈包围的防水透气膜 2， 同时接触容纳物 9与单向阀 1进 气口分别所在的两相邻腔室。 由于防水透气膜 2通常具有较低的透气率， 其同时 接触两相邻腔室部分的面积应大于单向阀 1进气口面积， 才能保证整个容器具有 及时排出多余气体的能力， 避免容器和防水透气膜 2承压失效。 事实上， 当容器 内压力升高迸行排气动作时， 防水透气膜 2都会被压向单向阀 1。 透气支撑单元 12应覆盖防水透气膜 2承压时向容器盖 6内壁位移较大的部分 （如膜的中心部 分）， 优选为完全覆盖防水透气膜 2同时接触两相邻腔室的部分 （密封圈包围部 分）。 本实施例采用的透气支撑单元 12为一个与密封垫 3的内径、 厚度都相同的 圆柱状海绵。 本实施例选择开孔率为 150dpi的聚氨酯海绵。 当容器内部压力升 高而快速排气时， 防水透气膜 2受压移向容器盖 6内壁， 防水透气膜 2与容器盖 6 内壁之间的海绵受两者挤压产生应变弹力， 阻挡防水透气膜 2移向容器盖 6内壁， 使多余的气体通过防水透气膜 2以后始终可以在海绵透气支撑单元 12中快速流 动， 到达单向阀 1的进气口排放， 从而保持容器足够的排气能力。
上述实施方式仅作为本发明的说明而非限制， 本发明保护范围还应包括那 些对于本领域普通技术人员来说显而易见的转换、 转化、 变化或替代， 以及在 本领域普通技术人员所具备的知识范围内， 还可以在不脱离本本实用新型宗旨 的前提下作出各种变化。
