Description

容器
技术领域
本发明涉及一种日常生活所用的容器， 特别是廉价、 适合大规模一体化 生产的容器及一种可以能够方便、 快速地取出容器内所容物的容器。 背景技术
现今生活中， 人民的生活用产品日益丰富， 洗手液、 洗衣液、 消毒液、 洗发液、 沐浴露、 牙膏、 酱油、 醋、 食用油、 液体药品、 化妆品、 保健品等 液体、 膏体产品日益丰富。 然而， 盛放上述产品的容器虽然形状各式各样， 但创新的结构非常少， 多年来没有重大改进， 存在的许多问题人们已经习以 为常。
比如， 生活中没有定量取出的容器。 人们在必须定量取出的时候往往借 助其他有刻度的容器才能实现定量取出， 有时还是用 "2.5 瓶盖" 这样粗糙 的计量方法。 这样一是操作不便， 二是计量不准， 三是容易造成产品的污染 或者浪费。
比如， 在加压取出容器内所容物时， 只是挤压容器壁或者向容器主体内 充气等方法加压。 这种加压方法的缺点是， 一是因为引进大量空气， 造成产 品污染， 二是因为是向容器主体内加压， 需要较大的压力。
比如， 现在的塑料容器多为一次性的， 所容物用完后容器即成为垃圾。 即使容器回收也只是材料回收， 容器不再作为容器使用。 这造成了大量环境 污染和浪费。
比如， 用压取器取出的容器， 容器主体和压取器是分开生产然后结合使 用的， 压取器结构复杂， 不能和容器一体化生产， 这使得容器的生产和安装 成本较高； 容器使用完毕后， 压取器部分和容器主体都被作为垃圾抛弃。 压 取器深入容器内部的结合方式， 使压取器沾染所容物后难以回收利用。
这些司空见惯的问题容易被人忽略。 新颖取出方法的出现还需要有人长 期关注， 并另辟蹊径。 发明内容 为了解决上述现有技术中存在的没有方便地取用所容物的容器和器具 的问题， 本发明提供一种容器， 包括容器主体， 其中， 还包括由传压通道、 取物通道、 流出通道串联连接组成的压力通道； 所述传压通道主体依附于所 述容器主体壁上， 一端连通取物通道， 另一端能与外设加压部件相连接； 所 述传压通道通过通道内部的传压介质传递外设加压部件施加于传压通道内 的压力； 所述取物通道壁上有允许容器主体内所容物向压力通道流入的单向 阀门， 所述单向阀门开口于容器主体内部的底部； 流出通道为供所容物向所 述容器外流出且能防止所容物倒流的通道。
这种容器结构筒单， 能大规模生产， 对产品结构没有过分精密的要求， 能降低生产成本； 没有向外过分突出的部分， 方便包装和运输。 在使用时和 外设的加压部件结合后， 能够实现方便、 快捷、 定量的取出。 外设的加压部 件即加压部件不和容器一体生产或者销售， 而是在使用容器时才安装加压部 件。
这种容器的压力通道主体依附于容器主体上（流出通道的流出口可能除 外） ， 这样的容器没有过多的凸起等， 不容易损坏。
外设的加压部件结构筒单， 筒单安装既可以使用； 加压部件不和所容物 接触， 没有污染， 回收容易被使用者接受。
很明显， 上述容器中传压通道的作用至少包括以下几点： 1、 能根据需 求传递压力， 使压力传递尽量少地受到通道形状的影响， 使容器形状的设计 更自由； 2、 由于传压介质移动的起始点能够固定， 这使对取出体积的计量 更为筒单， 而若在流出通道计量流出体积需要另设起始点和移动参照物， 结 构更为复杂； 3、 传压通道往往能位于容器上壁或者侧壁， 用户读取传压通 道上标示的体积刻度更为方便。
取物通道是指能与容器主体连通的单向阀门所在的一小段压力通道， 其 连通传压通道和流出通道， 能将容器主体内的所容物取至压力通道内。
该容器中压力通道是内部压力随所容物的取出过程周期变化的通道。 加 压取出时， 压力通道内压力变大， 通道内所容物在压力作用下向外流出； 取 出后， 由于外设的加压部件的作用， 压力通道出现负压， 容器主体内的所容 物从取物通道进入压力通道； 随后压力达到平衡， 容器为下次的取出做好了 准备。 对于这种容器， 可以使传压通道与外设加压部件相连接接口的水平位置 高于容器主体内所容物满载液面。 目的是防止所容物在生产、 运输或者使用 过程中从接口处遗漏。
对于这种容器， 可以使压力通道依附于所述容器主体侧壁的主体部分呈 倒置的抛物线形。抛物线形的压力通道可以使液体流动更为顺畅，减少阻力， 使取出更方便。
对于这种容器， 可以使取物通道开口位于所述倒置的抛物线形的最低 端。 这样做可以使最后剩下的所容物也能被方便取出。
对于这种容器， 传压介质可以为液体。 由于液体的不可压缩性， 液体传 压介质能及时地传递压力， 并实现通过计量传压介质的移动体积得知所容物 流出体积。
对于这种容器， 可以在所述传压通道内设活塞， 活塞一侧为传压介质， 另一侧为所容物。活塞既可以移动传递压力，又可以分开传压介质和所容物， 防止混合造成污染。 传压介质可以选择低价、 流动性好的水， 避免所容物浪 费在传压通道内。
对于这种容器， 可以使压力通道口径整体一致。 压力通道口径整体一致 可以使液体流动更为顺畅， 减少阻力。
对于这种容器， 可以使压力通道转弯少且角度平緩。 角度平緩转弯的压 力通道可以使液体流动更为顺畅， 减少阻力， 使取出更方便。
对于这种容器， 可以使所述取物通道位于容器主体底壁上。 这样做可以 降低成本， 并使最后剩下的所容物也能被方便取出。
对于这种容器， 可以使所述传压通道位于容器主体侧壁和上部。 位于容 器主体侧壁和上部的刻度能让使用时观察更方便。
对于这种容器， 可以使外设的加压部件与所述传压通道的接口高于流出 通道流出口。 目的是防止使用时所容物意外流出。
对于这种容器， 可以使所述传压通道内设活塞， 活塞一侧为传压介质， 另一侧为加压介质。 活塞可以分开加压介质和传压介质， 并能够作为液体介 质移动的参照物。
对于这种容器， 可以使所述传压通道透明， 在外壁上标有体积刻度。 通 过观察传压通道内传压介质的移动体积（或距离） ， 得出所容物流出的体积 (或距离） 。
对于这种容器， 可以使所述传压通道标有刻度的部分位于容器主体的上 部。 位于容器主体的上部的刻度能使使用者使用时观察更方便。
对于这种容器， 可以使所述压力通道位于同一个平面上。 压力通道位于 同一个平面上转弯少， 可以使液体流动更为顺畅， 减少流动阻力。
对于这种容器， 可以使所述传压通道螺旋形盘绕于容器主体壁上。 这样 的容器传压通道较长， 其上面的体积刻度单位体积更小， 能使定量取出更精 确； 这样的容器传压通道较细， 加压需要的压力更小， 使取出更轻便。 当然， 传压通道既可以位于容器主体外壁上， 也可以位于容器主体内壁上， 还可以 位于容器主体壁内。
对于这种容器， 可以使所述传压通道呈弧形， 位于容器主体上壁上。 传 压通道呈弧形同样可以使传压通道更细更长， 使取出更精确更轻便； 位于容 器主体上壁使读取更方便。
为了解决全面背景技术中的问题， 满足人们更加科学的生活需要， 本发 明利用上述容器， 并将其结合加压部件， 提出了下述一种容器。 该容器包括 容器主体， 其中， 还包括加压部件和由传压通道、 取物通道、 流出通道串联 连接组成的压力通道； 所述传压通道主体依附于所述容器主体壁上， 一端连 通取物通道， 另一端能与加压部件相连接； 所述传压通道通过通道内部的传 压介质传递加压部件施加于传压通道内的压力； 所述取物通道壁上有允许容 器主体内所容物向压力通道流入的单向阀门， 所述单向阀门开口于容器主体 内部的底部； 流出通道为供所容物向所述容器外流出且能防止所容物倒流的 通道。
这种容器结构筒单， 使用方便， 可以方便的取出容器内的所容物， 具有 ^口下优点：
1、 取出时不需要倒置容器， 防止所容物和空气过多接触， 造成所容物 氧化或者污染。
2、 仅需要很小的力加压即可取出。 由于加压是仅向压力通道内加压， 依据液体传压的原理， 所需的压力远小于向容器主体内加压。
3、 该方案能降低容器制作成本。 压力通道依附于容器主体壁上， 利用 了容器主体壁， 降低了总材料用量； 压力通道使用与容器主体同样的材料即 可满足要求， 降低了精细材料的用量； 压力通道和容器主体一体成型的制作 工艺降低了制作成本。
4、 能完整取出所有所容物。 由于取物通道的单向阀门开口于容器主体 内部的底部， 最后剩下的所容物也能被方便取出。
5、 加压部件与传压通道的连接口高于容器主体内所容物液面， 能最大 程度上防止所容物意外流出。
6、 由于所容物只是从流出通道流出， 流出通道的防倒流部件和取物通 道的单向阀门可以防止流出通道内被意外污染的所容物和容器主体内所容 物混合， 造成损失扩大。
7、 可以直接使用， 不需要在使用前安装加压部件。
4艮明显， 这种容器中传压通道的作用同样至少包括以下几点： 1、 能根 据需求传递压力， 使压力传递尽量少地受到通道形状的影响， 使通道能随容 器的形状自由设计； 2、 由于传压介质移动的起始点能够固定， 这使对取出 体积的计量更为筒单， 而若在流出通道计量流出体积需要另设起始点和移动 参照物， 结构更为复杂； 3、 传压通道往往位于容器上壁或者侧壁， 用户读 取传压通道上设置的体积刻度更为方便。
同样， 该容器中压力通道是内部压力随所容物的取出过程周期变化的通 道。 加压取出时， 压力通道内压力变大， 通道内所容物在压力作用下向外流 出； 取出后， 由于加压部件的作用， 压力通道出现负压， 容器主体内的所容 物从取物通道进入压力通道，压力达到平衡，容器为下次的取出做好了准备。
对于这种容器， 可以在传压通道内设活塞， 活塞一侧为传压介质， 另一 侧为所容物。利用活塞既可以移动传递压力，又可以分开传压介质和所容物， 防止混合污染。
对于这种容器， 可以使所述传压通道呈弧形， 位于容器主体上壁上。 传 压通道呈弧形同样可以使传压通道更细更长， 使取出更精确更轻便； 位于容 器主体上壁使读取更方便。
进一步的， 可以使所述加压部件为活塞和加压杆连接的结构， 在加压杆 把手旁边的容器壁或者加压杆支撑体上标示刻度， 标示加压时加压杆移动到 此处时所容物流出的体积或长度。 用加压杆的移动距离表征流出的所容物体 积， 可以使移动操作和读数位置更接近， 更符合操作的习惯； 加压部件位于 上部， 更方便使用者操作和读取刻度。
对于这种容器， 可以让传压通道透明， 在外壁上标有体积刻度。 这样可 以实现定量取出。
对于这种容器， 可以让传压通道标有刻度的部分位于容器主体的上部。 位于容器主体的上部的刻度能使使用时观察更方便。
对于这种容器， 可以让传压通道位于容器主体侧壁和上部， 其目的同样 是使使用时观察更方便。
对于这种容器， 可以让所述压力通道口径整体一致。 压力通道口径整体 一致可以使液体流动更为顺畅， 减少阻力。
对于这种容器， 可以让所述压力通道转弯少且角度平緩。 其目的也是让 液体流动更为顺畅， 减少阻力。
对于这种容器， 可以让取物通道位于容器主体底壁上。 这样做可以降低 成本， 使最后剩下的所容物也能被方便取出。
对于这种容器， 可以让部分容器主体壁是可移动的， 这样能通过改变容 器的体积来平衡容器内外压力差。
对于这种容器， 可以让加压部件位于能提起容器的把手上。 这样能使使 用者单手操作。
对于这种容器， 可以让加压部件与传压通道的连接口高于流出通道流出 口。
对于这种容器， 加压部件可以让传压通道内的活塞和加压杆， 与活塞连 接的杆状物伸出传压通道外。 通过杆状物向活塞加压更直接， 需要的力量较 少。
对于这种容器， 可以使所述加压部件为活塞和加压杆连接的结构， 在加 压杆把手旁边的容器壁或者支撑体上标示刻度， 标示加压时加压杆移动到此 处时所容物流出的体积或长度。 用加压杆的移动距离表征流出的所容物体 积， 可以使移动操作和读数更接近， 更符合操作的习惯； 加压部件位于上部， 更方便使用者读取刻度。
对于这种容器， 可以让加压部件为具有回弹功能的嚢状物， 所述嚢状物 的开口与传压通道的加压端相连通。 使用具有回弹功能的嚢状物， 加压后自 动回弹， 产生负压， 使容器主体内所容物进入压力通道， 容器随即可以进行 第二次取出。
进一步的， 可以在上述容器传压通道内设活塞， 活塞一侧为加压介质， 另一侧为传压介质。 活塞可以分开加压介质和传压介质， 并能够标示所容物 取出的体积。
进一步的， 上述容器加压介质为液体。 液体介质不可压缩， 能很好的传 递压力， 并以自身移动的体积代表所容物移动的体积。
进一步的， 可以让上述容器的传压介质为容器内所容物。 这样可以避免 其他种类的传压介质污染所容物。
进一步的， 可以让上述容器加压部件内的加压介质密度小于传压通道内 传压介质的密度。 由于加压介质位于上部， 密度较小时可以防止两者混在一 起。
对于加压部件是嚢状物的容器， 还可以使嚢状物有两端， 一端设置连通 传压通道的通道； 另一端设置连通外界气体的气体通道， 该气体通道上设置 能向外打开的单向阀门和能关闭气体通道的阀门。 目的是能通过操作嚢状物 及其上阀门使传压通道内所容物液面或者传压通道内的活塞位于设定的初 始位置， 便于取出定量。
进一步的， 可以在嚢状物连通传压通道的通道设置有能关闭通道的阀 门。 该阀门可以使液面或者活塞定位更加便捷。
这种带加压部件的容器， 同样克服了现有技术容器中存在的种种问题， 具备节省材料、 防止漏液、 使用方便、 重复利用、 取用轻便、 不易损坏、 重 现性好、 防止产品污染、 节省所容物、 能精确取出、 结构筒单， 实用性强， 不易损坏、 用途广泛等优点。 同时， 该容器可以容量较大、 可以循环使用的 特点， 减少塑料等各种包装的应用， 有利于减轻环境污染压力。 附图说明

如图 1所示， 为根据本发明实施例 1所述的一种容器。 该容器主体部分 1呈圓柱形， 内装液体所容物 2, 液体所容物上面为活塞 3 , 活塞 3可以在主 体部分 1 内上下移动。 在主体部分 1的侧壁上， 有传压通道 4、 取物通道 5 和流出通道 6串联连接组成的压力通道依附于主体部分的侧壁和底壁上。
传压通道 4由透明材料组成， 上面标示有刻度 9。 在传压通道 4上端口 有活塞 8,活塞 8可以沿传压通道 4向下移动，突起 10阻止活塞 8向上移动。 活塞 8上有螺孔 12, 可以连接加压杆。
取物通道 5上有单向阀门 11 , 单向阀门 11允许容器主体部分 1内的液 体进入压力通道， 不允许压力通道内的液体进入容器主体 1内。 单向阀门 11 位于底壁上， 开口于容器内的最低处。
流出通道 6的开口与挡板 10的位置平齐， 内部设置单向阀门 7 , 防止流 出通道 6内的所容物倒流。 流出通道 6的开口处设盖子 13 , 在取出所容物前 打开， 取出后盖上。
上述容器结构筒单， 生产加工方便， 生产成本相对较低； 外形规整， 方 便包装的运输。在活塞 8上安装加压杆后，即可以方便地取出容器内所容物。 由于活塞 8移动带动的所容物的体积等于从流出通道 6流出的所容物体积， 所以从活塞 8流出通道 6上的刻度变化可以读出流出的所容物体积。 由于活 塞 3可以上下移动， 所以当容器主体 1内所容物流出后， 活塞 3会在大气压 作用下下移。 由此外界气体不能和容器主体 1及压力通道内的所容物接触， 不会造成所容物污染或者氧化。
实施例 2
如图 2所示， 为根据实施例 2所述的一种容器。 该容器包括容器主体 1 , 容器主体 1上部有灌装口， 灌装所容物 2后用仅允许小分子气体通过的薄膜 3封住灌装口。 该容器还包括倾斜地依附于容器主体 2上壁和侧壁上的压力通道， 压力 通道由传压通道 4、 取物通道 5和流出通道 6串联连接组成， 压力通道位于 同一平面上。 传压通道 4一部分位于容器主体 1上壁上， 一部分位于容器主 体 1侧壁上。 取物通道 5上的单向阀门 10位于压力通道最低端， 开口于容 器主体内部的低处。 流出通道 6内部设有防止所容物倒流的薄片 7。 薄片 7 能向所容物流出方向转动一定角度， 当所容物企图倒流时会垂直于流出通道 6壁， 阻塞流出通道 6, 防止所容物倒流。
传压通道 4位于容器主体 1上壁和侧壁的部分区域透明， 在透明区域标 示有刻度 9。 在压力通道的开口即传压通道 4的开口处， 旋有螺纹 8, 螺纹 8 可以与外设的加压部件比如加压气嚢连接。
上述容器同样结构筒单， 生产加工方便， 生产成本相对较低； 外形规整， 方便包装的运输； 压力通道平滑， 取出过程也很轻便。 在螺纹 8处安装加压 气嚢后可以方便的定量取出所容物。 而且， 由于气嚢具备恢复原状的功能， 所以当每次加压取出后， 气嚢回弹， 则容器主体 1内的所容物在压力通道内 的负压作用下进入压力通道。 由于薄膜 3能进入空气， 容器主体 1内的所容 物进入压力通道后， 空气从薄膜 3进入容器主体 1 , 内外压力达到平衡， 容 器为下次取出做好了准备。
实施例 3
如图 3、 图 4所示， 为根据实施例 3所述的一种盛放所容物的容器， 图 4为单向阀门的放大图。 该容器主体部分 1呈圓柱形， 内装液体所容物 2, 液体所容物上面有活塞 3 , 活塞 3可以在主体部分 1内上下移动。 在主体部 分 1的侧壁上， 有传压通道 4、 取物通道 5和流出通道 6串联连接组成的压 力通道依附于主体部分的侧壁和底壁上。 其中， 传压通道 4螺旋形依附于主 体部分外壁， 流出通道 6依附于主体部分内壁， 流出通道 6开口位于容器外 部。
传压通道 4由透明材料组成， 上面标示有刻度 9。 在传压通道 4上端口 有活塞 8, 活塞 8可以沿传压通道 4螺旋向下移动， 突起 10阻止活塞 8向上 移动。 活塞 8上有螺孔， 可以连接螺旋状加压杆。
取物通道 5上有单向阀门， 该阀门由球状物 13、 喇叭形通道 14和弹簧 15组成。 该阀门允许容器主体部分 1内的液体进入压力通道， 不允许压力通 道内的液体进入容器主体 1内。 单向阀门位于底壁上， 单向阀门开口于容器 内的最低处。
流出通道 6的开口与突起 10的位置平齐， 内部设置单向阀门 7, 防止流 出通道 6内的所容物倒流。 流出通道 6的开口处设盖子 16, 在取出所容物前 打开， 取出后盖上。
上述容器在活塞 8上安装加压杆后， 根据液体压力传递的原理， 即可以 轻便地取出容器内所容物。 传压通道 4很长， 可以精确地取出较大体积的所 容物。 由于活塞 8移动带动的所容物的体积等于从流出通道 6流出的所容物 体积，所以从活塞 8在传压通道 4上的刻度变化可以读出流出的所容物体积。 由于活塞 3可以上下移动， 所以当容器主体 1内所容物流出后， 活塞 3会在 大气压作用下下移。 由此外界气体不能和容器主体 1及压力通道内的所容物 接触， 不会造成所容物污染或者氧化。
实施例 4
如图 5所示， 为根据实施例 4所述的一种容器。 该容器包括容器主体 1 , 内装所容物， 上设开口 3。 容器主体 1上部安装有把手 2。 把手 2内部为细 长型气嚢 4。 气嚢 4位于把手 2和压板 8之间， 使用者提起把手 2用手指挤 压压板 8, 气嚢 4 内的气体能被挤出， 向连通的压力通道等加压。 在把手 2 和压板 8之间还有弹簧 12。 当取出完成停止加压后， 压板 8在弹簧 12的作 用下回到原来的位置， 带动气嚢 4复原。 气嚢 4仅有一大一小两个开口， 大 的开口连接压力通道 13的传压通道端。 气嚢 4小的开口连通气道 10, 气道 10连通仅一端开口的气袋 11。 气袋 11上有磁性材料， 和流出口 15相吸引。 气袋 11位于流出通道 7流出口 15上部。 加压时， 气袋 11充气伸展， 流出 通道 7流出口 15打开； 停止加压后， 气嚢 4回弹产生负压， 气袋 11泄气下 垂， 阻塞流出通道 7的流出口 15 , 防止流出通道 7内液体回流。
压力通道由传压通道 5、 取物通道 6和流出通道 7串联连接组成。 传压 通道 5位于容器主体 1侧壁和底壁上，取物通道 6位于容器主体 1的底壁上， 流出通道 7的主体部分位于容器主体 1侧壁和底壁上。
传压通道 5内为液体， 自与气嚢 4的连接口向下标有刻度， 不加压时液 面的高度位于零刻度处。 传压通道 5下部有活塞 16, 活塞 16能在传压通道 5内移动， 并分开传压通道 5内的液体和取物通道 6中的所容物。 取物通道 6上有阀门 14。 阀门 14的长度大于开口 13的长度， 能完全封 住开口 13。 阀门 14可以向下转动 30度角。
取用所容物时， 使用者提起容器的把手 2, 将流出口 15对准投料处， 挤 压压板 8, 气嚢 4向一大一小两个开口施压。 连通小的开口的气袋 11充气伸 直， 流出通道 7的流出口 15打开； 连通大的开口的传压通道 5受压内部液 体向下移动， 推动活塞 16移动。 阀门 14在所容物移动的压力下向上转动， 直至开口 13关闭。 压力通道内的所容物在传压通道 5传递的压力作用下沿 流出通道 7向夕卜流出。
取出所容物后， 使用者停止加压， 压板 8在弹簧 12的作用下弹开， 气 嚢 4复原产生负压。 气袋 11泄气垂下； 压力通道内产生负压， 气袋 11紧贴 流出口 15 , 使流出通道 7内的所容物不能回流。 阀门 14向下转动， 开口 13 打开， 容器主体 1内所容物进入压力通道。 传压通道 5内液体在负压作用下 向上移动， 活塞 16向左向上移动复原， 容器主体 1 内所容物充满传压液体 外的压力通道。 外部气体通过开口 3进入容器主体 1 , 内外压力达到平衡， 容器为下次取出做好准备。
实施例 5
如图 6所示， 为根据实施例 5所述的一种容器。 该容器包括容器主体 1 , 上设开口 2。 容器主体 1呈圓柱形， 内部灌装所容物 3后用只允许气体进入 的单向阀门 13封闭该开口 2。 该单向阀门 13在容器主体 1内的气体压力小 于外部压力时打开。
钢丝 4螺旋状盘绕在容器主体 1上部， 钢丝 4下端与传压通道 5内起始 端的活塞 14固定连接。 钢丝 4最上端连接有方便按压加压的按钮 8。 钢丝 4 外部包有起支撑作用的支撑架 9。 支撑架 9上有刻度 10, 自按钮 8所在的最 上端位置起， 标示按钮 8移动到此处时流出的所容物体积。
压力通道为由传压通道 5、 取物通道 6和流出通道 7串联组成， 其内压 力随钢丝 4向上或向下转动而变化。
传压通道 5螺旋形盘绕与容器主体 1外壁上， 其螺旋的半径和匝间隔与 钢丝 4相同， 匝数是钢丝 4的匝数的一倍。 在传压通道 5内中间的位置， 设 置活塞 15。 活塞 14与活塞 15之间为液体传压介质。
取物通道 6位于容器主体 1的底壁上， 上设通向容器主体 1内部的单向 阀门 11。 单向阀门 11允许容器主体 1内所容物 3进入压力通道。 流出通道 7主体位于容器主体 1内壁上， 内部有防止所容物倒流的单向 阀门 12。 流出通道 7终端穿过容器主体 1壁， 流出口 16位于容器主体 1夕卜。
取用所容物时， 使用者按压钢丝 4上的按钮 8, 向压力通道加压， 活塞 14、 15向下移动， 单向阀门 11关闭， 单向阀门 12打开， 压力通道内所容物 向外流出。 当按钮 8到达指定的刻度位置时， 停止加压， 此事流出的所容物 体积即为标示的体积。
取用所容物后， 使用者将按钮 8螺旋上移， 钢丝 4带动活塞 14上移， 活塞 15上移， 单向阀门 12关闭， 单向阀门 11打开， 容器主体 1 内的所容 物进入并充满活塞 15至单向阀门 12之间的压力通道。 容器主体 1内压力下 降， 外部气体从单向阀门 13进入容器主体 1 内， 内外压力达到平衡。 此时 可以进行下一次取出了。

加压部件由活塞 4和加压杆 5组成， 活塞 4位于传压通道 6内， 不加压 时位于传压通道 6的起始端。 加压杆 5呈弧形， 水平于容器主体 1上壁上。 与加压杆 5相邻的容器主体 1上壁上， 标示有刻度 11 , 标示加压杆 5起始端 移动到此处时所容物流出的体积。
压力通道为由传压通道 6、 取物通道 7和流出通道 8串联组成， 主体位 于容器主体壁上。 其内压力随加压杆 5的转动方向不同而变化。
传压通道 6上半部呈弧形， 位于容器主体 1上壁上， 与加压杆 5位于同 一平面上； 传压通道 6下半部位于容器主体侧壁和底壁上。 传压通道 6内活 塞 4与活塞 12之间的传压介质为液体。 活塞 12与取物通道 7之间的传压介 质为所容物。 取物通道 7位于容器主体 1底壁上， 上有单向阀门 9开口于容 器主体 1内。 单向阀门 9包括釘状塞子 91和喇叭口 92; 喇叭口 92开口于容 器主体 1内。 流出通道 8内有单向阀门 10。
想取出若干体积的所容物时， 首先让所容物充满压力通道内活塞 12 以 下的所有空间 （上次取出后已经充满） ， 然后转动加压杆 5 , 使加压杆端部 移动到指定的体积刻度。 加压杆 5移动过程中， 活塞 4和活塞 12同时移动， 单向阀门 9关闭， 单向阀门 10打开。 所容物从流出通道 8流出的体积即为 指定的体积。
