Description

单向阀及液体容器 技术领域
[0001] 本发明涉及一种用于容器顶部的容器阀门结构， 尤其是一种单向阀及液体容器。
背景技术
[0002] 目前， 市场上的塑料单向阀， 由于其硅胶阀片以及阀内腔的设计缺陷， 在使用时会偶 尔产生不正常的现象， 锁定时漏气或错误锁定； 运用到盛装液体的容器时， 因受到湿气的影 响， 更会频频失效。
[0003] 现有的不可重新灌装容器在剩余小量液体时挤压不出液体， 导致浪费。
发明内容
[0004] 本发明的目的是提供一种结构简单、 功能可靠的单向阀及液体容器。
[0005] 本发明的目的是通过以下技术方案实现的：
一种单向阀， 包括硅胶阀体、 阀盒上盖和阀盒下盖， 所述阀盒上盖设有气孔， 所述阀盒下盖 设有进气脚； 所述的硅胶阀体包括外环和内环， 内环的内部为封闭的阀片， 所述内环和外环 之间通过弹性片连接， 所述外环固定在所述阀盒上盖和阀盒下盖之间， 所述内环在阀盒上盖 和阀盒下盖之间为悬空状态。
[0006] 一种液体容器， 该液体容器的顶部设有上述的单向阀。
[0007] 本发明的有益效果： 所述单向阀及液体容器， 由于硅胶阀体包括外环和内环， 内环的 内部为封闭的阀片， 内环和外环之间通过弹性片连接， 外环固定在阀盒上盖和阀盒下盖之间， 内环在阀盒上盖和阀盒下盖之间为悬空状态， 能有效避免气体带进的水蒸气或液体粘住硅胶 阀体， 并有效避免腔体内侧面对硅胶阀体正常动作的干扰， 大幅度提升单向阀的工作效率。 本发明的单向阀可使用于不同用途的容器上， 例如装盛饮料、 皂液或内部填充其他液体的软 管容器， 控制容器内部的气体封闭或流通状态， 结构简单、 功能可靠。
附图说明
[0008] 图 1为本发明的单向阀的结构示意图。
[0009] 图 2是本发明的单向阀中的硅胶阀体的立体图。
[0010] 图 3是本发明的单向阀中的硅胶阀体的立体剖视图。
[0011] 图 4是本发明的单向阀中的阀盒上盖的立体图。
[0012] 图 5是本发明的单向阀中的阀盒下盖的立体图。
[0013] 图 6是本发明的液体容器的结构示意图。 [0014] 图中： 1、 单向阀， 2、 硅胶阀体， 3、 阀盒上盖， 4、 阀盒下盖， 5、 外环， 6、 内环， 7、 弹性片， 8、 承托环， 9、 进气脚， 10、 气孔， 11、 内球面； 12、 出水杯， 13、 瓶身。 具体实施方式
[0015] 下面将结合附图对本发明实施例作进一步地详细描述。
[0016] 如图 1-5所示， 一种单向阀 1， 其包括硅胶阀体 2、 阀盒上盖 3和阀盒下盖 4， 所述阀 盒上盖 3设有气孔 10， 所述阀盒下盖 4设有进气脚 9; 所述的硅胶阀体包括外环 5和内环 6， 内环 6的内部为封闭的阀片， 所述内环 6和外环 5之间通过弹性片 7连接， 所述外环 5固定 在所述阀盒上盖 3和阀盒下盖 4之间， 所述内环 6在阀盒上盖 3和阀盒下盖 4之间为悬空状 态。
[0017] 硅胶阀体 2的外环 5被阀盒上盖 3和阀盒下盖 4夹住， 不能移动。
[0018] 所述阀盒下盖 4设有承托环 8， 所述外环 5的下表面设置在所述承托环 8上， 所述外 环的上表面被所述阀盒上盖 3压住。
[0019] 硅胶阀体 2的外环 5被阀盒下盖 4的承托环 8托起， 通过连接外环 5和内环 6的弹性 片 7的作用， 使阀体 2的内环 6在阀盒内自然形成悬空状态。
[0020] 阀盒上盖 3和阀盒下盖 4是紧密配合没有间隙， 气体不能通过两者之间的接触面而漏 气， 且阀盒上盖 3和阀盒下盖 4之间设有防脱扣 （图中未示出） 扣住不会脱离。
[0021] 如图 2和图 3所示， 硅胶阀体 2内有三个弹性片 7均匀分布连接阀体的外环 5和内环 6， 内环 6处在腔体中间， 不跟腔体内侧面接触， 只能保持平行的上下活动， 不会受到腔体内 侧壁磨擦的干扰， 故能有效锁气。 可以理解， 弹性片 7的数量不限三个， 其数量可以为复数 个， 即可为两个或两个以上， 且可以均匀分布。
[0022] 所述阀盒上盖的内表面为内球面， 当空气从阀盒下盖 4的进气脚 9冲进阀盒内， 所有 气体几乎全部作用于阀体内环 6下圈， 快速把内环 6托起， 使内环 6上圈紧贴阀盒上盖 3的 内球面 11， 阻止空气从阀盒上盖气孔 10散出。 从进气脚 9上冲的空气撤销后， 阀体内的三 个弹性片 7把内环 6及其封闭阀片向下拉回到原位形成悬空状态， 由于阀体的内环 6悬空在 阀体盒内， 不会跟上下盖接触， 能有助避免气体带进的水蒸气或液体粘着硅胶阀体在下盖面 和上盖面上， 从而避免由此引起的漏气和错误锁气的现象， 保持单向阀的正常功能。
[0023] 如图 6所示， 一种不可重复灌装的液体容器， 包括出水杯 12、 瓶身 13、 单向阀 1， 其 中单向阀 1是安插在瓶顶上， 出水杯 12设于瓶身 13的下口处， 出水杯 12内 （或瓶身 13的 下口处） 装有出水阀 （图中未示出）， 出水阀本身具有止流作用， 只有瓶身 13受到挤压时才 会流出液体。 [0024] 自然状态下， 由于瓶身 13 的下口处的出水阀 （图中未示出） 具有止流作用， 液体不 会流出， 当装有液体的瓶身 13每受到挤压一次， 由于单向阀 1的作用， 瓶内气体受阻不能向 上逸出， 从而作用于液体， 使液体通过出水杯 12向下流出； 当瓶身 13受的挤压力撤离时， 出水阀恢复到自然状态，液体不再流出， 同时气体通过单向阀 1进入瓶内，瓶身 13恢复原状。
[0025] 该液体容器可以为饮料瓶、 皂液瓶或酒瓶等。
[0026] 该液体容器可以包括柔性材质的瓶身。
[0027] 以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不局限于此， 任 何熟悉本技术领域的技术人员在本发明披露的技术范围内， 可轻易想到的变化或替换， 都应 涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应该以权利要求书的保护范围为准。
