底盖开启装置 7441还包括: 阻挡部 74, 该阻挡部 74形成在该连接 体 C的套管部 7的端部, 用于在开启底盖 B时阻止所述止动部 41 的旋 转。 连接体 C具有一体形成的裙部 6、 套管部 7以及阻挡部 74, 形成于 裙部 6内圆周面上的螺纹部分 60与容器开口部 8外圆周面上的螺紋部分 80相啮合, 将连接体 C同容器开口部 8连接起来, 由此连接体 C能够安 装在容器 D上, 并且盖体 A安装在该连接体 C上, 由此封闭容器 D的开 口。 该阻挡部 74可以大体沿该连接体 C的套管部 7的轴向方向从套管部 7的端部延伸。 套管部 7同裙部 6—体地形成, 并且沿轴向延伸成两端开 放的管状, 以允许腔管部 3插入, 所述盖体 A的腔管部 3插入该连接体 C的套管部 7中。 根据不同的结构, 所述盖体 A的腔管部 3可以从该连 接体 C的套管部 7的下端露出预定长度或不露出。 该连接体 C的套管部 7 的上侧部分 70 的直径大于连接体 C 的套管部 7 的下侧部分 72 的直 径, 而盖体 A的腔管部 3的上侧部分 30的直径大于盖体 A的腔管部 3 的下侧部分 32的直径。 该连接体 C的套管部 7的上侧部分 70的内表面 与盖体 A的腔管部 3的上侧部分 30的外表面至少在部分轴向长度上形成 密封接触。 该连接体 C的套管部 7的下侧部分 72的内表面与盖体 A的 腔管部 3的下侧部分 32的外表面可以至少在部分轴向长度上形成密封接 触。 根据本发明的一个实施例, 连接体 C的套管部 7的上侧部分 70和下 侧部分 72之间形成偏移部 71, 使得下侧部分 72呈现比上侧部分 70相对 收缩的管状, 并且, 套管部 7上侧部分 70的尺寸使得其内圆周面紧密地 同腔管部 3上侧部分 30外圆周面接触, 连接体 C的套管部 7下侧部分 72的尺寸使得其内圆周面紧密地同腔管部 3下侧部分 32外圆周面接触。 并且, 形成于连接体 C的套管部 7上端开口外圆周面上的螺紋部分 73与 形成于盖体 A的裙部 1 内圆周面上的螺纹部分 10相啮合, 将连接体 C 同盖体 A连接起来。 而且, 薄的切口 61沿着位于裙部 6下圆周边缘部分 的整个圆周形成, 从而在位于裙部 6 的下圆周边缘部分形成卡环 62, 使 得裙部 6在切口 61上侧的部分可以强行与裙部 6在切口 61下侧的卡环 62发生分离。 防滑滚花 63形成于切口 61上方的裙部 6的外圆周面上。
连接体 C的阻挡部 74 由形成于套管部 7下端开口圆周边缘上多个 阻挡齿 75 构成, 阻挡齿 75 由大量沿启封方向的逆向锯齿以凸起方式形 成, 每个阻挡齿 75 具有三角形形状, 其中一个斜边 76 的凸起高度朝向 其下端减小, 另一个为垂直边 77, 如图 2 (A) 所示。 在启封时连接体 C 的阻挡齿 75与底盖 B的止动齿 42啮合, 以阻挡底盖 B随盖体 A在启封 方向上旋转。
其中, 形成于盖体 A的裙部 1 内圆周面上的螺纹部分 10与形成于 连接体 C的套管部 7上端开口外圆周面上的螺纹部分 73相啮合, 螺紋部 分 10和螺纹部分 73构成第一组螺紋, 形成于底盖 B的裙部 4内圆周面 上的螺纹部分 40与形成于腔管部 3 下端开口外圆周面上的螺纹部分 33 相啮合, 螺纹部分 40和螺紋部分 33 构成第二组螺紋, 上述两组螺纹具 有相等的螺距, 并且第一组螺纹的螺纹数目多于第二组螺紋的螺纹数 目, 使得在分配盖启封时上述两组螺紋同步退行, 消除了上述两组螺纹 相互的轴向作用力和相关部件因此造成变形的可能性, 并且保证底盖 B 脱落后第一组螺纹仍保持部分啮合, 盖体 A仍保持封闭套管部 Ί上端开 口的状态, 从而保证了底盖 B启封后容器开口部 8仍然处于密封状态。
具有第一实施例结构的分配盖以下述方式装配和启封。
如图 3所示, 将盖体 A的腔管部 3插入连接体 C的套管部 7开口内 并拧紧相啮合的一组螺纹, 直到裙部 1的卡环 12经过连接体 C的套管部 7上端开口外圆周面的环形凸起 78, 使得卡环 12被环形凸起 78啮合并 被锁定, 并且原料 E同压力气体一起被从倒置朝上的腔管部 3 下端开口 供应到盖体 A的腔管部 3中。
如图 4所示, 底盖 B的环形凹进部分 51 以及盖体 A的腔管部 3下 端开口因以一组螺纹相啮合推进而被强制地彼此配合, 使得密封圈 52 的 凸起部分被腔管部 3 下端开口压缩。 因此, 腔管部 3 下端开口通过底盖 B 的关闭具有很高的密封性能, 即使压力气体被封装在腔管部 3 中, 其 液密性和气密性也能充分保证。
腔管部 3下端开口通过底盖 B以上述方式关闭以后, 底盖 B的止动 齿 42末端与连接体 C的阻挡齿 75末端之间在轴向上保持一定间距, 使 得底盖 B与腔管部 3下端开口能够充分拧紧, 并且保证在装配完毕后底 盖 B与腔管部 3下端开口的密封不会受到盖体 A与连接体 C相结合的一 组螺纹意外松动的影响。
按上述方式装配的连接体 C和盖体 A的腔管部 3连同底盖 B被插入 容器开口部 8 内部, 并且连接体 C在密封方向上旋转, 腔管部 3随着底 盖 B插入容器开口部 8内, 直至盖体 A将容器开口部 8密封起来, 如图 5所示。
当连接体 C在密封方向上旋转时, 其裙部 6的螺纹部分 60开始与 容器开口部 8 的螺纹部分 80相啮合, 并且随后螺紋部分 60与螺紋部分 80拧紧, 直到裙部 6的卡环 62经过容器幵口部 8外圆周面的环形凸起 81 , 使得卡环 62被环形凸起 81啮合并被锁定, 并且在盖体 A启封时这 种锁定状态也得以保持, 如图 6 (A) 和 6 (B ) 所示。
容器幵口部 8在上述状态下被密封起来。
如果盖体 A在启封方向上旋转, 而连接体 C同容器开口部 8在上述 这种密封并被锁定的状态下, 那么尽管盖体 A的裙部 1相对于切口 11的 上侧部分可以向上移动, 由于其卡环 12与环形凸起 78保持啮合, 所以 切口 11下方的卡环 12不能向上移动。 因此, 卡环 12在切口 11处与裙 部 1的上侧部分发生分离, 并且保持在这个位置。
因此, 既然盖体 A不能旋转, 除非能强制性地引起这种分离的足够 大的力被施加到盖体 A上, 所以盖体 A的密封状态必然能够保持。
另一方面, 在容器开口部 8中, 当盖体 A在启封方向上旋转时, 而 腔管部 3在被旋转时连同底盖 B 向上移动, 并且随着卡环 12在切口 11 处与裙部 1 的上侧部分发生强制性地分离而突然释放施加于盖体 A的向 下的作用力, 因此腔管部 3连同底盖 B突然上升一定距离, 使得底盖 B 的止动齿 42与连接体 C的阻挡齿 75相啮合, 如图 7所示。 然后, 底盖 B不能随腔管部 3旋转和向上移动。 因此, 底盖 B的螺纹部分 40与进一 步旋转和向上移动的腔管部 3的螺紋部分 33从啮合状态发生退行并继而 分离, 使得底盖 B从腔管部 3脱落, 如图 8所示。 当底盖 B脱落时, 腔 管部 3 中的原料 E 同压力气体一起突然喷出, 并且底盖 B 落入容器 D 内。
因为脱落的底盖 B的外径大于连接体 C的套管部 7开口的内径, 因 此它不会经过连接体 C的套管部 7开口到容器 D的外面。
应该注意到, 因为连接体 C 的阻挡部 74 由形成于套管部 7下端开 口圆周边缘上的多个阻挡齿 75构成, 那么因为底盖 B的止动齿 42与套 管部 7的阻挡齿 75啮合, 所以底盖 B的脱落肯定能够实现。
特别指出的是, 一方面, 盖体 A与连接体 C的套管部 7上端开口也 可以如此结合, 即形成于盖体 A的腔管部 3的上侧部分 30外圆周面上的 螺纹部分与连接体 c的套管部 7的上侧部分 70内圆周面上的螺纹部分相 啮合, 以将盖体 A与连接体 C连接起来。 由于盖体 A与连接体 C的上述 连接方式与本实施例构思不悖, 并且可以确切地实现本实施例的全部目 的, 因而可以归于本实施例的范围内。 因为盖体 A与连接体 C的上述连 接方式便于理解和实现, 所以在此并没有必要作出更详细的说明和图 示。
特别指出的是, 另一方面, 连接体 C与容器开口部 8也可以如此结 合, 即连接体 C的裙部 6的平滑内表面与容器开口部 8的平滑外表面相 对插入并紧密配合后, 通过超声波焊接、 热焊接或胶粘接等方法固定, 将连接体 C同容器开口部 8连接起来。 或者, 连接体 C与容器开口部 8 还可以如此结合, 即形成于连接体 C的套管部 7的上侧部分 70在位于肩 部 64下表面之下的外圆周面上的螺纹部分与容器开口部 8内圆周面上的 螺纹部分相啮合, 将连接体 C 同容器开口部 8连接起来。 或者, 连接体 C与容器开口部 8还可以如此结合, 即连接体 C的套管部 7的上侧部分 70在位于肩部 64下表面之下的外圆周的平滑外表面与容器开口部 8的平 滑内表面相对插入并紧密配合后, 通过超声波焊接、 热焊接或胶粘接等 方法固定, 将连接体 C同容器开口部 8连接起来。 由于连接体 C与容器 开口部 8 的上述各种连接方式与本实施例构思不悖, 并且可以确切地实 现本实施例的全部目的, 因而可以归于本实施例的范围内。 因为连接体 C 与容器开口部 8 的上述各连接方式便于理解和实现, 所以在此并没有 必要作出更详细的说明和图示。
第二实施例
第二实施例描述了第一实施例的分配盖的一种变型, 这种变型分配 盖与第一实施例的分配盖的区别在于, 其底盖 B和盖体 A的腔管部 3的 构建方式以及结合方式发生了相应的改变。
参考图 9和图 10, 展示了根据本发明第二实施例的分配盖。 与参考 图 1 (A) 到图 8的第一实施例的分配盖相似, 第二实施例的分配盖也包 括三个部分, 由硬质塑料模制成的整体盖体 A、 由硬质塑料模制成的整 体底盖 B和由硬质塑料模制成的整体连接体 C, 以及同盖体 A可分离的 一体地模制而成的圆盘形硬质塑料上盖 20。 而且, 必要时, 上盖 20上具 有薄片件 21。
尤其是, 底盖 B的裙部 4a为其端部 5a圆周边缘的凸出延伸部分, 底盖 B和腔管部 3下端开口如此形成并封闭, 即形成于底盖 B的端部 5a 朝向裙部 4a幵口方向凸起的圆筒部分 53外圆周面上的螺纹部分 54与形 成于腔管部 3下端开口内圆周面上的螺纹部分 33a相啮合。
与上面描述的参考图 1 (A) 至图 8的第一实施例的分配盖相似, 底 盖 B的止动部 41 由形成于底盖 B的裙部 4a开口圆周边缘上的多个止动 齿 42 构成, 止动齿 42 由大量沿启封方向的逆向锯齿以凸起方式形成于 圆周边缘上, 每个止动齿 42具有三角形形状, 其中一个斜边 43 的凸起 高度朝向其下端减小, 另一个为垂直边 44。 在启封时止动部 41与套管部 7下端的阻挡部 74相啮合。
通过具有上述结构的第二实施例的分配盖, 与上述第一实施例的分 配盖相似, 将盖体 A的腔管部 3插入连接体 C的套管部 7开口内并拧紧 后, 连接体 C和盖体 A的腔管部 3连同底盖 B被插入容器开口部 8 内 部, 并且连接体 C在密封方向上旋转。 腔管部 3能够随着底盖 B而插入 容器开口部 8内, 直至盖体 A将容器开口部 8密封起来, 如图 9所示。
如果盖体 A在启封方向上旋转以将腔管部 3连同裙部 1一起旋转并 向上移动, 同时容器开口部 8在上述这种密封状态, 随着盖体 A的裙部 1的卡环 12在切口 11处与裙部 1的上侧部分发生强制性地分离而导致腔 管部 3连同底盖 B的突然上升, 底盖 B的止动齿 42与连接体 C的阻挡 齿 75相啮合, 然后, 底盖 B不能随腔管部 3旋转和向上移动。 因此, 底 盖 B的螺紋部分 54同进一步旋转和向上移动的腔管部 3的螺纹部分 33a 从啮合状态发生退行并继而分离,.使得底盖 B 与进一步旋转并向上移动 的腔管部 3发生分离, 当底盖 B脱落时, 腔管部 3中的原料 E同压力气 体一起突然喷出, 并且底盖 B落入容器 D内, 如图 10所示。
第三实施例
第三实施例描述了第一实施例分配盖的另一种变型, 这种变型分配 盖与第一实施例分配盖的区别在于, 其盖体 A的腔管部 3 的构建方式发 生了改变。
参考图 1 1和图 12, 展示了参考图 1 (A) 到图 8的第一实施例分配 盖的另一种变型。 参考图 11和图 12, 与第一实施例分配盖相似, 第三实 施例的分配盖也包括三个部分, 由硬质塑料模制成的整体盖体 A、 由硬 质塑料模制成的整体底盖 B 和由硬质塑料模制成的整体连接体 C, 需要 注意的是, 由于腔管部 3的变型发生在腔管部 3上端形成容器 D排出口 的位置, 所以上盖 20和薄片件 21的形成位置也发生了相应的变化。
尤其是, 这种变型分配盖的盖体 A的腔管部 3上端向上通过形成于 腔管部 3的容器 D排出口轴向和径向延伸, 同盖体 A—体地形成另一个 容器 F的腔体, 并且, 在容器 F的腔体的端部 2a上形成容器 F的上端开 口, 同容器 F可分离的一体地模制而成的圆盘形硬质塑料上盖 20将容器 F的上端开口封闭, 而且, 必要时, 上盖 20上具有薄片件 21。
由于这种变型分配盖是在第一实施例分配盖的基础上, 其腔管部 3 上端在盖体 A 的端部上表面向上轴向和径向延伸而产生的局部变型, 所 以这种变型分配盖的其它部件的构建方式与第一实施例分配盖的其它部 件的构建方式并不需要发生必须的改变, 并且, 这种变型分配盖的装配 和启封方式与第一实施例分配盖相似, 如图 11和图 12所示。
第四实施例
第四实施例描述了第三实施例分配盖的一种变型, 这种变型分配盖 与第三实施例分配盖的区别在于, 其阻挡部 74在连接体 C上形成的位置 发生了改变, 并因此, 连接体 C的套管部 7和盖体 A的腔管部 3的构建 方式也发生了相应的改变, 而且, 启封时在容器 D内由连接体 C的阻挡 部 74和底盖 B的止动部 41形成的底盖开启装置 7441发生啮合的位置也 发生了相应的改变。
参考图 13和图 14, 展示了参考图 1 1和图 12的第三实施例的分配 盖的一种变型。 与第三实施例分配盖相似, 第四实施例的分配盖也包括 三个部分, 由硬质塑料模制成的整体盖体 A、 由硬质塑料模制成的整体 底盖 B和由硬质塑料模制成的整体连接体 C, 以及同盖体 A—体地形成 的容器 F 和同容器 F 可分离的一体地模制而成的圆盘形硬质塑料上盖 20, 而且, 必要时, 上盖 20上具有薄片件 21。
尤其是, 这种变型分配盖与第三实施例分配盖的区别在于, 这种变 型分配盖的连接体 C的套管部 7同裙部 6—体地形成, 然而, 连接体 C 的套管部 7下端并没有向下轴向延伸, 而是与连接体 C的肩部 64的下表 面保持在同一水平面上, 与上面描述的参考图 1 (A) 到图 8的第一实施 例的分配盖相似, 套管部 7 沿裙部 6 的轴向向上延伸成开放的管状, 以 允许腔管部 3插入, 其中套管部 7的相对上侧部分 70a和下侧部分 72a 之间形成偏移部 71a, 使得下侧部分 72a呈现比上侧部分 70a相对收缩的 管状。 并且, 连接体 C 的肩部 64 的下表面内侧圆周边缘上形成阻挡部 74, 用于与形成于底盖 B的裙部 4开口圆周边缘上的止动部 41相啮合, 以阻挡底盖 B随盖体 A在启封方向上旋转。
另一方面, 腔管部 3 从盖体 A的裙部 1与容器 F结合部的收缩的圆 周下表面整体地向下延伸, 并且具有足够从套管部 7 开口内延伸到肩部 64的长度, 进一步超过肩部 64的下表面, 其中腔管部 3上侧部分 30a和 下侧部分 32a之间形成偏移部 31a, 使得其下侧部分 32a呈现比上侧部分 30a相对收缩的管状, 并且, 腔管部 3上侧部分 30a的尺寸使得其外圆周 面紧密地同套管部上侧部分 70a 内圆周面接触, 腔管部 3 下侧部分 32a 的尺寸使得在其外圆周面紧密地同套管部下侧部分 72a 内圆周面接触。 而且, 形成于腔管部 3下端开口外圆周面上螺紋部分 33与形成于底盖 B 的裙部 4内圆周面上的螺紋部分 40相啮合, 将底盖 B同腔管部 3下端开 口连接起来。
通过具有上述结构的第四实施例的分配盖, 与上述第三实施例的分 配盖相似, 将盖体 A的腔管部 3插入连接体 C的套管部 7开口内并拧紧 后, 将连接体 C和盖体 A的腔管部 3连同底盖 B与容器开口部 8连接, 并且连接体 C在密封方向上旋转, 将容器开口部 8密封起来, 如图 13所 示
如果盖体 A在启封方向上旋转以将腔管部 3连同裙部 1一起旋转并 向上移动, 同时容器开口部 8在上述这种密封状态, 随着盖体 A的裙部 1的卡环 12在切口 1 1处与裙部 1的上侧部分发生强制性地分离而导致腔 管部 3连同底盖 B的突然上升, 底盖 B的止动齿 42与连接体 C的阻挡 齿 75相啮合, 然后, 底盖 B不能随腔管部 3旋转和向上移动。 因此, 底 盖 B的螺紋部分 40同进一步旋转和向上移动的腔管部 3 的螺纹部分 33 从啮合状态发生退行并继而分离, 使得底盖 B 与进一步旋转并向上移动 的腔管部 3发生分离, 当底盖 B脱落时, 腔管部 3中的原料 E同压力气 体一起突然喷出, 并且底盖 B落入容器 D内, 如图 14所示。 第五实施例
第五实施例描述了第二实施例的分配盖的一种变型, 这种变型分配 盖与第二实施例的分配盖的区别在于, 其底盖 B上形成的支撑部 55同盖 体 A的腔管部 3上形成的限位槽 35嵌合, 使得底盖 B在启封后不至于 脱落到容器 D内。
参考图 15 到图 18, 展示了根据本发明第五实施例的分配盖。 分配 盖还包括: 底盖掉落防止装置 5735, 底盖掉落防止装置 5735包括: 与所 述底盖 B的圆筒部分 53连接的支撑部 55, 该支撑部 55具有从所述底盖 B 的圆筒部分轴向延伸的支撑件 56 和形成在支撑件 56 的端部的突缘 57; 以及形成在盖体 A的腔管部 3 中的限位槽 35, 该限位槽 35能够与 突缘 57接合, 以防止底盖 B从盖体 A脱落。 该支撑件 56可以具有大体 圆筒状的形状, 而突缘 57 具有大体圆环状的形状, 并且至少一个开口 5657形成在所述大体圆筒形状的支撑件 56中。
具体而言, 与第二实施例的分配盖相似, 第五实施例的分配盖也包 括三个部分, 由硬质塑料模制成的整体盖体 A、 由硬质塑料模制成的整 体底盖 B和由硬质塑料模制成的整体连接体 C, 以及同盖体 A可分离的 一体地模制而成的圆盘形硬质塑料上盖 20。 而且, 必要时, 上盖 20上具 有薄片件 21。
尤其是, 这种变型分配盖通过在底盖 B的端部 5a朝向裙部 4a开口 方向凸起的圆筒部分 53的上表面上进行同时模制, 一体地形成底盖 B的 支撑部 55, 该支撑部 55具有与圆筒部分 53 的上表面同心且退进的圆周 面上均匀分布的几个支撑件 56, 几个支撑件 56的末端各自一体地形成可 弹性变形的突缘 57 的几个分隔的圆弧部分, 可弹性变形的突缘 57 的几 个分隔的圆弧部分共同构成大体呈圆环状的外形, 该突缘 57的环形外径 朝向底盖 B 的裙部 4a的开口方向收缩, 从而形成导向面 58, 其下表面 形成径向凸出几个支撑件 56所在圆周面的阶梯部分 59, 如图 16所示。
另一方面, 盖体 A的腔管部 3下端内圆周面上形成呈环形凹进的限 位槽 35, 该限位槽 35具有与突缘 57的环形外径互补形状的导向面 36和 阶梯部分 37。
通过具有上述结构的第五实施例的分配盖, 当底盖 B在密封方向上 旋转以将支撑部 55 插入腔管部 3 下端开口时, 该可弹性变形的突缘 57 变形, 以允许支撑部 55插入腔管部 3内, 在突缘 57通过限位槽 35时, 由于突缘 57的导向面 58与限位槽 35的导向面 36相互作用, 使得突缘 57通过限位槽 35, 直到底盖 B与腔管部 3 下端开口结合的一组螺紋拧 紧, 如图 15所示。
当底盖 B在启封方向上旋转以将底盖 B与腔管部 3下端开口充分分 离时, 可弹性变形的突缘 57嵌入限位槽 35, 由于突缘 57的阶梯部分 59 被限位槽 35的阶梯部分 37阻挡, 从而限制了底盖 B与腔管部 3下端开 口进一步分离, 如图 17所示。 然后, 在密封方向上旋转盖体 A直到拧 紧, 此时原料 E通过支撑件 56的几个开口 5657落入容器 D内, 由于底 盖 B被支撑部 55保持在腔管部 3的下端, 所以底盖 B不至于落入容器 D 内, 如图 18所示。
显而易见, 本发明第二实施例至第五实施例都是在第一实施例的基 础上进行的单因素变型或递进变型, 上述第一实施例至第五实施例主要 是为了对本发明第一实施方案进行解释和使得本发明第一实施方案便于 理解, 然而, 在本发明第一实施方案的构思和范围内, 还包括许多上述 单因素变型或递进变型的组合变型。
第六实施例
参考图 19 (A) 到图 26, 展示了根据本发明第六实施例的分配盖。 根据本发明第六实施例的分配盖包括: 盖体 A, 该盖体 A用于封闭容器 D 的开口, 并包括用于容纳原料的腔管部 3 以及形成在该腔管部 3 的端 部的开口; 底盖 B, 所述底盖 B能够与腔管部 3 的端部以螺紋方式连接 从而封闭所述腔管部 3 的端部的开口, 其中所述底盖 B具有裙部 4; 以 及底盖开启装置 9041a, 该底盖开启装置 9041a包括: 形成在所述底盖 B 的裙部 4的端部的止动部 41a。
具体而言, 根据本发明第六实施例的分配盖包括三个部分, 由硬质 塑料模制成的整体盖体 A、 由硬质塑料模制成的整体底盖 B 和一体地模 制在容器颈口 9凹进部分的阻挡部 90, 以及同盖体 A可分离的一体地模 制而成的圆盘形硬质塑料上盖 20。 而且, 必要时, 上盖 20上具有薄片件 21。 上盖 20和薄片件 21用于覆盖形成于盖体 A的端部 2的容器 D的排 出口。
盖体 A整体模制而成, 包括裙部 1、 端部 2以及从端部 2向下延伸 的腔管部 3。 用于与容器开口部 8外圆周面上的螺紋部分 80相啮合的螺 纹部分 10形成于裙部 1内圆周面上。 而且, 薄的切口 11沿着位于裙部 1 下圆周边缘部分的整个圆周形成, 从而在位于裙部 1 的下圆周边缘部分 形成卡环 12, 使得裙部 1在切口 11上侧的部分可以强行与裙部 1在切口 1 1下侧的卡环 12发生分离。 防滑滚花 13形成于切口 11上方的裙部 1的 外圆周面上。
腔管部 3从端部 2下表面整体地向下延伸, 并且具有足够从容器开 口部 8 内部延伸到容器 D 内的长度, 进一步超过容器颈口 9 的凹进部 分, 其中腔管部 3上侧部分 30b和下侧部分 32b之间形成偏移部 31b, 使 得其下侧部分 32b呈现比上侧部分 30b相对收缩的管状, 并且, 腔管部 3 上侧部分 30b 的尺寸使得其外圆周面紧密地同容器开口部 8 内圆周面接 触, 同时, 腔管部 3 下侧部分 32b 的尺寸使得其外圆周面与容器颈口 9 内圆周面之间形成环形凹进部分 34。
底盖 B整体模制而成, 底盖 B具有一体形成的裙部 4、 端部 5 以及 止动部 41a, 形成于裙部 4 内圆周面上的螺纹部分 40与形成于腔管部 3 下端外圆周面上的螺紋部分 33相啮合, 将底盖 B同腔管部 3下端开口连 接起来, 止动部 41a形成于底盖 B的裙部 4开口圆周边缘上, 用于与形 成于容器颈口 9凹进部分的阻挡部 90相啮合, 环形凹进部分 51 形成于 底盖 B的端部 5内表面 50圆周边缘, 通过在环形凹进部分 51的内表面 上同环形凹进部分 51 进行同时模制而一体地形成由比环形凹进部分 51 更加柔软的材料制成的环形密封圈 52, 这种材料比如硅像胶或者丙烯橡 胶。 密封圈 52显著地嵌在底部中, 并且与环形凹进部分 51 成为一体, 使得其部分从环形凹进部分 51的内表面凸出。 防滑滚花 45形成于裙部 4 外圆周面上。
底盖 B的止动部 41a由形成于底盖 B的裙部 4开口圆周边缘上呈径 向开放的多个可弹性变形的止动齿 42a 构成, 可弹性变形的止动齿 42a 由大量沿启封方向的逆向锯齿以凸起方式形成于呈径向开放的截锥外圆 周面上, 每个止动齿 42a具有三角形形状, 其中一个斜边 43a 的凸起高 度朝向其下端减小, 另一个为垂直边 44a, 如图 20 (B ) 所示。 可弹性变 形的止动齿 42a 的环形外径通过弹性变形来改变, 止动齿 42a 的外径大 于容器开口部 8的内径, 可弹性变形环形止动齿 42a在插入容器开口部 8 时, 被容器开口部 8闭合起来并收缩在腔管部 3下端的环形凹进部分 34 内, 以允许底盖 B进入容器 D 内, 然后, 可弹性变形环形的止动齿 42a 恢复到打开状态, 且在启封时与容器颈口 9凹进部分的阻挡齿 91啮合。
底盖开启装置 9041a还可以包括: 阻挡部 90, 阻挡部 90 由形成于 容器颈口 9凹进的圆周上多个阻挡齿 91构成, 容器颈口 9凹进部分的阻 挡齿 91 由大量沿启封方向的逆向锯齿以凸起方式形成于环形齿的外圆周 面上, 每个阻挡齿 91 具有三角形形状, 其中一个斜边 92 的凸起高度朝 向其下端减小, 另一个为垂直边 93, 如图 20 (A) 所示。 在分配盖启封 时容器颈口 9凹进部分的阻挡齿 91与底盖 B的止动部 41a上的可弹性变 形的止动齿 42a 啮合, 以阻挡底盖 B 随盖体 A在启封方向上旋转。 并 且, 容器颈口 9 凹进部分的直径略大于可弹性变形的止动齿 42a在打开 状态下的外径, 以保证底盖 B在启封后脱落。
其中, 形成于盖体 A的裙部 1 内圆周面上的螺纹部分 10与形成于 容器开口部 8外圆周面上的螺纹部分 80相啮合, 螺紋部分 10和螺紋部 分 80构成第一组螺纹, 以及形成于底盖 B的裙部 4内圆周面上的螺纹部 分 40与形成于腔管部 3下端开口外圆周面上的螺紋部分 33相啮合, 螺 纹部分 40和螺紋部分 33 构成第二组螺紋, 上述两组螺纹具有相等的螺 距, 并且第一组螺纹的螺纹数目多于第二组螺纹的螺紋数目, 使得在分 配盖启封时上述两组螺紋同步退行, 消除了上述两组螺纹相互的轴向作 用力和相关部件因此造成变形的可能性, 并且保证底盖 B 脱落后第一组 螺纹仍保持部分啮合, 盖体 A仍保持封闭容器开口部 8的状态, 从而保 证了底盖 B启封后容器 D仍然处于密封状态。
具有第六实施例结构的分配盖以下述方式装配和启封。
如图 21 所示, 原料 E同压力气体一起被从倒置朝上的腔管部 3下 端开口供应到盖体 A的腔管部 3中。
如图 22所示, 底盖 B的环形凹进部分 51以及盖体 A的腔管部 3下 端开口因以一组螺纹相啮合推进而被强制地彼此配合, 使得密封圈 52 的 凸起部分被腔管部 3 下端开口压缩。 因此, 腔管部 3 下端开口通过底盖 B 的关闭具有很高的密封性能, 即使压力气体被封装在腔管部 3 中, 其 液密性和气密性也能充分保证。
腔管部 3下端开口通过底盖 B以上述方式关闭以后, 盖体 A的腔管 部 3连同底盖 B被插入容器开口部 8 内, 并且盖体 A在密封方向上旋 转。 当底盖 B被推入容器开口部 8内时, 因为在止动齿 42a的外圆周面 上的大量的止动齿 42a 具有朝向其下端减小的凸起高度, 所以当止动齿 42a被顺畅地推入时, 止动齿 42a弹性变形到关闭状态, 并收缩在腔管部 3下端的环形凹进部分 34内, 当止动齿 42a与容器开口部 8内圆周面滑 动接触时, 腔管部 3能够随着底盖 B而插入容器开口部 8内, 如图 23所 示。
另一方面, 在容器开口部 8 中, 因为腔管部 3具有足够的长度以深 入容器 D内部, 所以底盖 B经过容器 D中的颈口 9凹进部分时, 其止动 齿 42a恢复到打开状态, 且与颈口 9 凹进部分的凹进的圆周上多个阻挡 齿 91处于非啮合的状态, 以允许盖体 A在密封方向上进一步旋转, 直至 拧紧。 此时, 底盖 B的止动齿 42a末端与颈口 9凹进部分的阻挡齿 91末 端之间在轴向上保持一定间距, 使得底盖 B与腔管部 3 下端开口的密封 不会受到盖体 A与容器开口部 8结合的一组螺纹意外松动的影响。 按上 述方式装配的盖体 A的腔管部 3连同底盖 B被插入容器开口部 8内部, 并且盖体 A在密封方向上旋转, 腔管部 3能够随着底盖 B而插入容器开 口部 8 内, 直至盖体 A将容器幵口部 8密封起来, 如图 24 (A) 和 24 (B ) 所示。
当盖体 A在密封方向上旋转时, 裙部 1 的螺纹部分 10开始与容器 开口部 8 的螺纹部分 80相啮合, 并且随后与螺纹部分 80拧紧, 直到裙 部 1 的卡环 12经过容器开口部 8外圆周面的环形凸起 81, 使得卡环 12 被环形凸起 81啮合并被锁定。
容器开口部 8在上述状态下被密封起来。
如果盖体 A在启封方向上旋转, 而容器开口部 8在上述这种密封状 态下, 那么尽管裙部 1相对于切口 11 的上侧部分可以向上移动, 由于其 卡环 12与环形凸起 81保持啮合, 所以切口 1 1 下方的卡环 12不能向上 移动。 因此, 卡环 12在切口 1 1 处与裙部 1 的上侧部分发生分离, 并且 保持在这个位置。
因此, 既然盖体 A不能旋转, 除非能强制性地引起这种分离的足够 大的力被施加到盖体上, 所以盖体 A的密封状态必然能够保持。
另一方面, 在容器开口部 8中, 当盖体 A在启封方向上旋转时, 而 腔管部 3在被旋转时连同底盖 B 向上移动, 并且随着卡环 12在切口 11 处与裙部 1 的上侧部分发生强制性地分离而突然释放施加于盖体 A的向 下的作用力, 因此腔管部 3连同底盖 B突然上升一定距离, 使得底盖 B 的止动齿 42a与颈口 9凹进部分的阻挡齿 91相啮合, 然后, 底盖 B不能 随腔管部 3 旋转和向上移动, 如图 25所示。 因此, 底盖 B 的螺紋部分 40与进一步旋转和向上移动的腔管部 3的螺纹部分 33从啮合状态发生退 行并继而分离, 使得底盖 B从腔管部 3脱落, 如图 26所示。 当底盖 B脱 落时, 腔管部 3中的原料 E同压力气体一起突然喷出, 并且底盖 B落入 容器 D内。
因为脱落的底盖 B 在其止动齿 42a 处具有恢复了其打开状态的外 径, 该外径大于容器开口部 8 的内径, 因此它不会经过容器开口部 8 到 容器的外面。
应该注意到, 因为阻挡部 90 由形成于容器 D颈口 9凹进的圆周上 多个阻挡齿 91构成, 那么因为底盖 B的止动齿 42a与容器 D颈口 9的阻 挡齿 91啮合, 所以底盖 B的脱落肯定能够实现。
特别指出的是, 一方面, 阻挡部 90也可以形成于由硬质塑料模制成 的整体管状套筒下端开口的圆周边缘上, 该管状套筒具有与容器开口部 8 内圆周面紧密配合的外径尺寸, 将管状套筒插入容器开口部 8, 通过超声 波悍接、 热悍接或胶粘接等方法固定, 使得管状套筒下端幵口的圆周在 容器 D的颈口 9的位置形成凹进的圆周, 阻挡部 90处在上述凹进的圆周 内。 由于阻挡部 90 的上述形成方式与本实施例构思不悖, 并且可以确切 地实现本实施例的全部目的, 因而可以归于本实施例的范围内。 因为阻 挡部 90 的上述形成方式便于理解和实现, 所以在此并没有必要作出更详 细的说明和图示。
特别指出的是, 另一方面, 盖体 A 与容器开口部 8 也可以如此结 合, 即形成于盖体 A的腔管部 3 的上侧部分 30b外圆周面上的螺紋部分 与容器开口部 8 内圆周面上的螺纹部分相啮合, 以将盖体 A与容器开口 部 8连接起来。 由于盖体 A与容器开口部 8的上述连接方式与本实施例 构思不悖, 并且可以确切地实现本实施例的全部目的, 因而可以归于本 实施例的范围内。 因为盖体 A与容器开口部 8 的上述连接方式便于理解 和实现, 所以在此并没有必要作出更详细的说明和图示。
第七实施例
第七实施例描述了第六实施例的分配盖的一种变型, 这种变型分配 盖与第六实施例的分配盖的区别在于, 其底盖 B和盖体 A的腔管部 3的 构建方式以及结合方式发生了相应的改变。
参考图 27 和图 28, 展示了根据本发明第七实施例的分配盖。 与第 六实施例的分配盖相似, 第七实施例的分配盖也包括三个部分, 由硬质 塑料模制成的整体盖体 A、 由硬质塑料模制成的整体底盖 B 和一体地模 制在容器 D的颈口 9凹进部分的阻挡部 90, 以及同盖体 A可分离的一体 地模制而成的圆盘形硬质塑料上盖 20。 而且, 必要时, 上盖 20上具有薄 片件 21。
尤其是, 底盖 B的裙部 4a为其端部 5a圆周边缘的凸出延伸部分, 底盖 B和腔管部 3下端开口如此形成并封闭, 即形成于底盖 B的端部 5a 朝向裙部 4a开口方向凸起的圆筒部分 53外圆周面上的螺纹部分 54与形 成于腔管部 3下端开口内圆周面上的螺纹部分 33a相啮合。
与上面描述的参考图 19 (A) 到图 26的第六实施例的分配盖相似, 底盖 B的止动部 41a由形成于底盖 B的裙部 4a圆周边缘上呈径向开放的 多个可弹性变形的止动齿 42a构成, 可弹性变形的止动齿 42a 由大量沿 启封方向的逆向锯齿以凸起方式形成于呈径向开放的截锥外圆周面上, 每个止动齿 42a具有三角形形状, 其中一个斜边 43a 的凸起高度朝向其 下端减小, 另一个为垂直边 44a。
通过具有上述结构的第七实施例的分配盖, 与上述第六实施例的分 配盖相似, 当盖体 A在密封方向上旋转以用力将底盖 B推入容器开口部 8内时, 止动齿 42a开始与容器开口部 8内圆周面滑动接触, 止动齿 42a 的外径大于容器开口部 8 的内径, 可弹性变形环形止动齿 42a在插入容 器开口部 8时, 被容器开口部 8 闭合起来并收缩在腔管部 3下端的环形 凹进部分 34内, 以允许底盖 B迸入容器 D内, 然后, 当止动齿 42a经过 容器中的颈口 9 时, 它们恢复到初始打开状态, 且与颈口 9 凹进部分的 凹进的圆周上多个阻挡齿 91处于非啮合的状态, 以允许盖体 A在密封方 向上进一步旋转, 直至拧紧。 此时, 底盖 B 的止动齿 42a末端与颈口 9 凹进部分的阻挡齿 91末端之间在轴向上保持一定间距, 使得底盖 B与腔 管部 3下端开口的密封不会受到盖体 A与容器开口部 8结合的一组螺纹 意外松动的影响。 按上述方式装配的盖体 A的腔管部 3连同底盖 B被插 入容器幵口部 8 内部, 并且盖体 A在密封方向上旋转, 腔管部 3能够随 着底盖 B而插入容器开口部 8 内, 直至盖体 A将容器开口部 8密封起 来, 如图 27所示。
如果盖体 A在启封方向上旋转以将腔管部 3连同裙部 1一起旋转并 向上移动, 同时容器开口部 8在上述这种密封状态, 随着盖体 A的裙部 1的卡环 12在切口 1 1处与裙部 1的上侧部分发生强制性地分离而导致腔 管部 3连同底盖 B的突然上升, 底盖 B的止动齿 42a与容器颈口 9凹进 部分的阻挡齿 91 相啮合, 然后, 底盖 B不能随腔管部 3 旋转和向上移 动。 并且, 容器颈口 9 凹进部分的直径略大于可弹性变形的止动齿 42a 在打开状态下的外径, 以保证底盖 B在启封后脱落, 所以底盖 B的螺紋 部分 54与进一步旋转和向上移动的腔管部 3的螺纹部分 33a从啮合状态 发生退行并继而分离, 使得底盖 B 与进一步旋转并向上移动的腔管部 3 发生分离, 如图 28所示。 当底盖 B脱落时, 腔管部 3中的原料 E同压力 气体一起突然喷出, 并且底盖 B落入容器 D内。
第八实施例
第八实施例描述了第六实施例分配盖的另一种变型, 这种变型分配 盖与第六实施例分配盖的区别在于, 其盖体 A的腔管部 3 的构建方式发 生了改变。
参考图 29和图 30, 展示了参考图 19 (A) 到图 26的第六实施例分 配盖的另一种变型。 与第六实施例分配盖相似, 第八实施例的分配盖也 包括三个部分, 由硬质塑料模制成的整体盖体 A、 由硬质塑料模制成的 整体底盖 B和一体地模制在容器 D的颈口 9凹进部分的阻挡部 90, 需要 注意的是, 由于腔管部 3的变型发生在腔管部 3上端形成容器 D排出口 的位置, 所以上盖 20和薄片件 21的形成位置也发生了相应的变化。
尤其是, 这种变型分配盖的盖体 A的腔管部 3上端向上通过形成于 腔管部 3的容器 D排出口轴向和径向延伸, 同盖体 A—体地形成另一个 容器 F的腔体, 并且, 在容器 F的腔体的端部 2a上形成容器 F的上端开 口, 同容器 F可分离的一体地模制而成的圆盘形硬质塑料上盖 20将容器 F的上端开口封闭, 而且, 必要时, 上盖 20上具有薄片件 21。
由于这种变型分配盖是在第六实施例分配盖的基础上, 其腔管部 3 上端在盖体 A 的端部上表面向上轴向和径向延伸而产生的局部变型, 所 以这种变型分配盖的其它部件的构建方式与第六实施例分配盖的其它部 件的构建方式并不需要发生必须的改变, 并且, 这种变型分配盖的装配 和启封方式与第六实施例分配盖相似, 如图 29和图 30所示。
第九实施例
第九实施例描述了第八实施例分配盖的一种变型, 这种变型分配盖 与第八实施例分配盖的区别在于, 其阻挡部 90在容器开口部 8上形成的 位置发生了改变, 并因此, 盖体 A的腔管部 3 的构建方式也发生了相应 的改变, 而且, 启封时在容器 D内由阻挡部 90和底盖 B的止动部 41a形 成的底盖开启装置 9041a发生啮合的位置也发生了相应的改变。
参考图 31和图 32, 展示了参考图 29和图 30的第八实施例的分配 盖的一种变型。 与第八实施例分配盖相似, 第九实施例的分配盖也包括 三个部分, 由硬质塑料模制成的整体盖体 A、 由硬质塑料模制成的整体 底盖 B 和形成于容器 D 开口上端内圆周面上呈径向收缩的内壁凸起 82 下表面的阻挡部 90, 以及同盖体 A—体地形成的容器 F和同容器 F可分 离的一体地模制而成的圆盘形硬质塑料上盖 20, 而且, 必要时, 上盖 20 上具有薄片件 21。
尤其是, 这种变型分配盖与第八实施例分配盖的区别在于, 这种变 型分配盖在容器 D开口上端内圆周面上形成呈径向收縮的内壁凸起 82, 阻挡部 90形成于内壁凸起 82的下表面, 用于与形成于底盖 B的裙部 4 开口圆周边缘上的止动部 41a相啮合, 以阻挡底盖 B随盖体 A在启封方 向上旋转。 另一方面, 腔管部 3 从盖体 A的裙部 1与容器 F结合部的收縮的圆 周下表面整体地向下延伸, 并且通过内壁凸起 82开口, 进一步超过内壁 凸起 82的下表面, 其中腔管部 3上侧部分 30c和下侧部分 32c之间形成 偏移部 31c, 使得其下侧部分 32c呈现比上侧部分 30c相对收缩的管状, 并且, 腔管部 3 上侧部分 30c 的尺寸使得其外圆周面紧密地同内壁凸起 82幵口内圆周面接触, 同时, 腔管部 3下侧部分 32c的尺寸使得其外圆 周面与内壁凸起 82开口内圆周面之间形成环形凹进部分 34。 同时, 内壁 凸起 82具有足够的轴向尺寸, 使得即使在底盖 B启封脱落时, 腔管部 3 上侧部分 30c外圆周面仍紧密地同内壁凸起 82开口内圆周面接触, 从而 保持容器 D的密封状态。 并且, 形成于底盖 B的裙部 4内圆周面上的螺 纹部分 40与形成于腔管部 3下端开口外圆周面上螺纹部分 33相啮合, 将底盖 B与腔管部 3下端开口连接起来。
通过具有上述结构的第九实施例的分配盖, 与上述第八实施例的分 配盖相似, 当盖体 A在密封方向上旋转以用力将底盖 B推入容器开口部 8 内时, 止动齿 42a开始与内壁凸起 82开口内圆周面滑动接触, 止动齿 42a的外径大于内壁凸起 82开口的内径, 可弹性变形环形止动齿 42a在 插入内壁凸起 82开口时, 被内壁凸起 82开口闭合起来并收縮在腔管部 3 下端的环形凹进部分 34 内, 以允许底盖 B进入容器 D开口内, 然后, 当止动齿 42a经过内壁凸起 82的下表面时, 它们恢复到初始打开状态, 且与内壁凸起 82下表面的阻挡齿 91 处于非啮合的状态, 以允许盖体 A 在密封方向上进一步旋转, 直至拧紧。 此时, 底盖 B 的止动齿 42a末端 与内壁凸起 82下表面的阻挡齿 91 末端之间在轴向上保持一定间距, 使 得底盖 B与腔管部 3下端开口的密封不会受到盖体 A与容器开口部 8结 合的一组螺纹意外松动的影响。 按上述方式装配的盖体 A的腔管部 3连 同底盖 B被插入容器开口部 8内部, 并且盖体 A在密封方向上旋转, 腔 管部 3能够随着底盖 B而插入容器开口部 8内, 直至盖体 A将容器幵口 部 8密封起来, 如图 31所示。
如果盖体 A在启封方向上旋转以将腔管部 3连同裙部 1一起旋转并 向上移动, 同时容器开口部 8在上述这种密封状态, 随着盖体 A的裙部 1的卡环 12在切口 1 1处与裙部 1的上侧部分发生强制性地分离而导致腔 管部 3连同底盖 B的突然上升, 底盖 B的止动齿 42a与容器开口部 8的 阻挡齿 91 相啮合, 然后, 底盖 B不能随腔管部 3 旋转和向上移动。 因 此, 底盖 B的螺纹部分 40同进一步旋转和向上移动的腔管部 3的螺紋部 分 33从啮合状态发生退行并继而分离, 使得底盖 B与进一步旋转并向上 移动的腔管部 3发生分离, 当底盖 B脱落时, 腔管部 3中的原料 E同压 力气体一起突然喷出, 并且底盖 B落入容器 D内, 如图 32所示。
特别指出的是, 阻挡部 90也可以形成于由硬质塑料模制成的整体环 状套筒下端开口的圆周边缘上, 该环状套筒具有与容器开口部 8 内圆周 面紧密配合的外径尺寸, 并且具有类似本实施例所述内壁凸起 82 的形 状, 将环状套筒插入容器开口部 8 内, 通过超声波焊接、 热焊接或胶粘 接等方法固定。 由于阻挡部 90的上述形成方式与本实施例构思不悖, 并 且可以确切地实现本实施例的全部目的, 因而可以归于本实施例的范围 内。 因为阻挡部 90 的上述形成方式便于理解和实现, 所以在此并没有必 要作出更详细的说明和图示。
第十实施例
第十实施例描述了第七实施例的分配盖的一种变型, 这种变型分配 盖与第七实施例的分配盖的区别在于, 其底盖 B上形成的支撑部 55同盖 体 A的腔管部 3上形成的限位槽 35嵌合, 使得底盖 B在启封后不至于 脱落到容器 D内。
参考图 33 到图 36, 展示了根据本发明第十实施例的分配盖。 分配 盖还包括: 底盖掉落防止装置 5735, 底盖掉落防止装置 5735包括: 与所 述底盖 B的圆筒部分 53连接的支撑部 55, 该支撑部 55具有从所述底盖 B 的圆筒部分轴向延伸的支撑件 56 和形成在支撑件 56 的端部的突缘 57; 以及形成在盖体 A的腔管部 3 中的限位槽 35, 该限位槽 35能够与 突缘 57接合, 以防止底盖 B从盖体 A脱落。 该支撑件 56可以具有大体 圆筒状的形状, 而突缘 57 具有大体圆环状的形状, 并且至少一个开口 5657形成在所述大体圆筒形状的支撑件 56中。
具体而言, 与参考图 27和图 28的第七实施例的分配盖相似, 第十 实施例的分配盖也包括三个部分, 由硬质塑料模制成的整体盖体 A、 由 硬质塑料模制成的整体底盖 B和一体地模制在容器颈口 9凹进部分的阻 挡部 90, 以及同盖体 A可分离的一体地模制而成的圆盘形硬质塑料上盖 20。 而且, 必要时, 上盖 20上具有薄片件 21。
尤其是, 这种变型分配盖通过在底盖 B的端部 5a朝向裙部 4a开口 方向凸起的圆筒部分 53的上表面进行同时模制, 一体地形成底盖 B的支 撑部 55, 该支撑部 55具有在与圆筒部分 53 的上表面同心且退进的圆周 面上均匀分布的几个支撑件 56, 几个支撑件 56的末端各自一体地形成可 弹性变形的突缘 57 的几个分隔的圆弧部分, 可弹性变形的突缘 57 的几 个分隔的圆弧部分共同构成大体呈圆环状的外形, 该突缘 57 的环形外径 朝向底盖 B 的裙部 4a的开口方向收缩, 从而形成导向面 58, 其下表面 形成径向凸出几个支撑件 56所在圆周面的阶梯部分 59, 如图 34所示。
另一方面, 盖体 A的腔管部 3下端内圆周面上形成呈环形凹进的限 位槽 35, 该限位槽 35具有与突缘 57的环形外径互补形状的导向面 36和 阶梯部分 37。
通过具有上述结构的第十实施例的分配盖, 当底盖 B在密封方向上 旋转以将支撑部 55 插入腔管部 3 下端开口时, 该可弹性变形的突缘 57 变形, 以允许支撑部 55插入腔管部 3内, 在突缘 57通过限位槽 35时, 由于突缘 57的导向面 58与限位槽 35的导向面 36相互作用, 使得突缘 57通过限位槽 35, 直到底盖 B与腔管部 3 下端开口结合的一组螺紋拧 紧, 如图 33所示。
当底盖 B 在启封方向上旋转以将底盖 B 与腔管部 3 下端充分分离 时, 可弹性变形的突缘 57嵌入限位槽 35, 由于突缘 57的阶梯部分 59被 限位槽 35的阶梯部分 37阻挡, 从而限制了底盖 B与腔管部 3下端进一 步分离, 如图 35所示。 然后, 在密封方向上旋转盖体 A直到拧紧, 此时 原料 E通过支撑件 56的几个幵口 5657落入容器 D内, 由于底盖 B被支 撑部 55保持在腔管部 3 的下端, 所以底盖 B不至于落入容器 D内, 如 图 36所示。
显而易见, 本发明第七实施例至第十实施例都是在第六实施例的基 础上进行的单因素变型或递进变型, 上述第六实施例至第十实施例主要 是为了对本发明第二实施方案进行解释和使得本发明第二实施方案便于 理解, 然而, 在本发明第二实施方案的构思和范围内, 还包括许多上述 单因素变型或递进变型的组合变型。
一般地, 上述本发明实施例的分配盖, 包括经过变型的相应的分配 盖, 其中盖体 A、 底盖 B、 连接体 C和容器开口部 8分别地由包括硬质 塑料在内的材料模制而成, 并且分别通过在盖体 A、 底盖 B和连接体 C 的各自裙部 1、 裙部 4和裙部 6的外圆周面上进行同时模制、 一体地形成 由包括软质塑料在内的材料制成的防滑表面层, 而且防滑表面层经过滚 花处理。
在实际应用中, 上述本发明实施例的分配盖, 包括经过变型的相应 的分配盖, 其中覆盖于容器 D排出口的上盖 20和薄片件 21可以根据不 同应用领域的要求产生适合使用者需要的变型, 并采用符合卫生和安全 要求的材料制造, 例如将本发明实施例的分配盖应用于婴儿奶瓶, 可以 采用由硅橡胶、 胶乳 (LATEX) 橡胶或其它适当的材料制成奶嘴, 安装 于奶瓶排出口的位置, 以适合婴儿哺乳。

在许多情况下, 混合物需要被加热, 以便保证原料和内容物相互溶 解或分配, 分配盖和容器的腔体可以完全由非金属材料制造, 以便可以 在微波炉内直接加热原料和内容物的混合物。 另外, 分配盖和容器的腔 体由多种材料制成, 以便将容器放入沸腾或加热的液体, 例如水中, 对 容器内的内容物进行加热。 许多材料可以用于制造本发明的分配盖和容 器, 其包括采用塑料, 例如聚丙烯, 其中容器的腔体可以由硬质材料制 成具有固定形状的腔体, 也可以由软质材料制成具有可变形状的柔性腔 体。 密封圈可以由硅橡胶或者丙烯橡胶制成。 当使用本发明储存或分配 食品、 药品或化妆品时, 应当考虑, 分配盖和容器的材料应当符合由所 在国家的食品和药品管理机构或其他管理部门制定的规定标准。
尽管己经利用专用术语对本发明的组合方式进行了描述, 但是这种 描述仅仅是用于解释目的, 应该明白, 在不脱离所附权利要求的精神和 范围的条件下可以进行改变和变型;
例如, 各个实施例中的各个部分或结构可以组合在一起形成新的实 施例。
例如, 在上述实施例中, 作为止动部和阻挡部的示例分别描述了止 动齿和阻挡齿, 但是止动部和阻挡部可以是任何合适的凸起, 例如弹性 的或刚性的凸起, 并可以是具有任何合适形状的凸起。 止动部和阻挡部 也可以采用如下方式, 例如, 止动部和阻挡部中的一个是凸起, 而另一 个是凹部。 由此, 通过两者的接合阻止底盖在启封时旋转。
此外, 止动部和阻挡部可以是粗糙的表面, 当两个粗糙的表面接触 时, 可以阻止底盖在启封时旋转。
此外, 上述实施例中, 描述了作为止动部和阻挡部的示例的止动齿 和阻挡齿, 止动齿和阻挡齿都是多个齿, 作为选择, 止动齿和阻挡齿可 以都是一个齿, 或任意数量的齿。
此外, 止动部和阻挡部也可以是其它本领域公知的结构, 只要止动 部和阻挡部接触或接合时, 可以阻止底盖在启封时旋转。
