Description

一种可以限量取用所容物的容器及其取出方法 技术领域
本发明涉及一种容器及其取出方法， 尤其涉及一种可以限量取用所容物的容器及 其取出方法。
背景技术
随着生活水平的提高， 居民的科学意识也逐步增强。 科学家对生活中的细节， 比 如一日三餐的用油量、 用酱油量、 每次牙膏用量的倡议也得到了普遍的响应。 但是， 现在居民生活中常用的容器， 如盛放油、 酱、 醋以及牙膏的容器， 都没有限量、 定量 取出的功能。 每次使用， 都是凭经验随意取用。 取少时可以再加， 但取多了就只有多 用了。 实际用量过量， 科学家的倡议得不到落实； 各次取用的数量不同， 使得菜谱等 实际经验的效果得不到重现。
现在定量取用口服液体药品有两种方法， 一种是利用容器本身上有刻度， 二是借 助其他有刻度的容器。第一种方法取用的只是大概的体积，而且如果取过量了很麻烦： 倒回去可能污染整瓶药品， 不倒回去又没法处理。 第二种借助其他有刻度容器的方法 同样存在可能取过量的问题， 造成污染或者浪费。
广大居民需要一种简单、 实用的可以限量取用的容器， 使每次取用的体积不超过 设定的量。
发明内容
本发明旨在解决现有技术中存在的没有定量、 限量取用所容物容器的问题， 提供 一种可以限量取用所容物的容器。
该容器包括主体部分、 加压部分和流出通道， 其中主体部分包括气体空间和盛放 所容物的空间， 加压部分为向气体空间内的气体进行加压的装置， 流出通道为与盛放 所容物的空间连通供所容物流出的装置；
其中， 该容器还包括气道及其两端出口和流出通道内随所取用所容物的流出而移 动的移动部件， 第一端出口随所述移动部件的移动而移动， 第二端出口在所述主体部 分内所述气体空间里；
在所述气道第一端出口移动轨迹上， 设有开口， 所述开口与外界气体相连通， 并 在所述第一端出口移动到所述开口所在位置时所述开口与所述第一端出口相连通。
这种容器简单实用， 可以限量或者定量取出容器内所容物。
特别地， 还可以包括覆盖于所述第一端出口上的薄片， 所述开口设在该薄片上。 另外， 所述第一端出口和所述开口为长条形或者为依次排列的一列， 通过闭合长 条形开口除指定部分外的其他部分来选择出口； 通过闭合依次排列的一列开口除指定 出口外的其他出口来选择出口。 通过调节开口与外界气体间的距离， 调节每次量取所 容物的限量。 使用者可以在预先设定的选择范围内选择取出体积。 所述移动部件与所述第一端出口可以为一体设置或者为活动连接的分体设置。 随 所取所容物移动的部件与气道开口为一体装置时， 所述移动部件与气道开口固定连接， 同时前进或者后退； 为分体装置时， 两者活动连接， 由所述移动部件带动或者控制气 道开口的移动。
所述移动部件可以紧贴于所述流出通道内侧壁上。
所述移动部件上可以设有限制所容物向移动部件靠近主体部分一侧流动的装置。 比如单向阀或者其他装置。
所述加压部分在主体部分气体腔的开口外可以套有可充气胀大的装置， 比如薄膜 袋、 气球等。 目的是防止加压时加入的气体与液体接触。 在加压装置在主体部分气体 空间的开口外套一个可充气胀大的装置， 加压时加入的气体都收集在可膨胀的装置内。 此时如果主体部分上方气体空间所充的是惰性气体， 则在整个容器的液体取用过程中， 液体都不会与外界气体接触仅有惰性气体与液体接触。 这有利于更好的保护液体。 所 述第二端出口设在该可充气胀大的装置内， 可以避免惰性气体逸散， 使每次加压后与 外界气体连通时逸散的是加压气体。
无回縮性的薄膜袋可以使每次加压充入薄膜袋内的气体在压力降低后仍留在薄 膜袋内一部分， 在第二次取用所容物时就可以迅速使压力上升， 避免了下次使用时重 复加压， 可以使压力迅速上升。
在流出通道出口上方安装可以有用于遮挡灰尘的气袋， 所述气袋通过气体通道与 气体空间相通。 加压时， 气袋充气膨胀， 水平伸直， 使出口开放； 压力降低后， 流出 通道出口外上方的部分气袋在重力作用下下垂， 遮住出口。 这使得该容器使用更为方 便。
所述移动部件可以依靠与所容物移动时的摩擦力移动， 也可以依靠对气体空间加 压时传递过来的压力移动。 当所容物粘性大或者粘稠度大时， 可以依靠与所容物移动 时的摩擦力移动， 移动部件可以设在流出通道侧壁上， 由所容物移动带动移动部件移 动； 扩大移动部件接触面积可以有更好的定量量取效果。 当依靠对气体空间加压时传 递过来的压力移动是， 提高移动部件在流出通道内的横截面会让移动部件的灵敏度更 高， 会取得更好的定量、 限量效果。
加压装置优选一端进气一端出气可以连续多次加压的气囊。
下列措施可以使上述限量取用变为定量取用， 使每次取出的量接近或者等于所取 用的限量： 改进随所取所容物移动的部件， 提高其随所容物移动的灵敏度； 加强主体 部分、 移动部件和气道出口的气密性； 将气体通道开口设计成垂直于其运行轨迹的狭 长开口等。
该发明还涉及一种限量取出容器内所容物的方法。 该方法包括以下步骤：
A、 根据需要取出所容物的体积， 确定与用于加压的气体连通的气体出口从开始 移动到与外界气体连通需要移动的距离。
B、 用气体向盛放所容物的容器内加压， 推动所容物向出口通道移动； c、 所容物在移动过程中， 带动容器出口通道内移动部件随同移动；
D、 所述与用于加压的气体连通的气体出口随移动部件移动而移动；
E、 当所述气体出口移动到与容器外部气体连通时， 容器内的压力下降， 所容物 不再向外移动， 取出所容物过程结束。
所述气体出口是指随时与容器内气体连通的气体通道可与外界气体连通端。上述 方法简单、实用，可以不借助其他设备限量或定量取用容器内所容物，不会取出过量， 造成污染或者浪费。
这种限量取出容器内所容物的方法， 其中可以将向盛放所容物的容器内加压 的气体收集在容器内可膨胀的袋内。 而且， 其中可以将与所述气体出口连通的气 体通道在容器内的另一端开口开在可膨胀的袋内。这样做目的是防止加压时加入的 气体与液体接触。在加压装置在主体部分气体空间的开口外套一个可充气胀大的装置， 加压时加入的气体都收集在可膨胀的装置内。此时如果主体部分上方气体空间所充的 是惰性气体， 则在整个容器的液体取用过程中， 液体都不会与外界气体接触仅有惰性 气体与液体接触。 这有利于更好的保护液体。 所述第二端出口设在该可充气胀大的装 置上， 可以避免惰性气体逸散， 使每次加压后与外界气体连通时逸散的是加压气体。
这种限量取出容器内所容物的方法， 其中可以在向盛放所容物的容器内用气体加 压时， 加压气体同时向所述出口通道出口上方安装的用于遮挡灰尘的气袋加压， 所述 气袋加压后伸直， 使出口通道出口畅通。 这样做可以避免灰尘等污染出口， 又避免了 开启和关闭的操作步骤。
这种限量取出容器内所容物的方法， 所述确定与用于加压的气体连通的气体出口 需要移动的距离的方法可以为， 通过闭合所述气体出口运动轨迹上长条形开口除指定 部分外的其他部分或者依次排列的一列开口的指定出口外的其他出口来选择与外界 气体相连通的出口。这样做可以使取出物的体积在若干个预先设定的选择的范围内随 意选择。
这种限量取出容器内所容物的方法， 所述确定与用于加压的气体连通的气体出口 需要移动的距离的方法可以为， 通过插拔覆盖于长条形气体出口或者依次排列的一列 气体出口上的薄片来选择所述气体出口与外界气体相连通的最近出口。这样做可以使 取出物的体积在一定的选择范围内随意选择。
这种限量取出容器内所容物的方法， 所述移动部件可以位于容器所述出口通道内。 移动部件位于出口通道内， 可以使移动部件随所容物移动更为灵敏。
这种限量取出容器内所容物的方法， 在所述气体出口移动到与连通容器外部气体 连通后， 可以使用弹性部件牵引移动部件縮回到移动前所在位置。确保移动部件移 动前位置固定， 可以保证能反复限量或定量取用容器内所容物。
这种限量取出容器内所容物的方法， 可以将所述气体出口与所述移动部件一体设 置。 所述气体出口与所述移动部件一体设置可以减少容器部件， 使容器更为耐用， 取 出方法更为可靠。 这种限量取出容器内所容物的方法， 向盛放所容物的容器内加压可以使用一头进 气另一头出气的气囊。 这种气囊便于连续加压， 当容器内所容物体积较少、 气体体积 较大时仍能限量或定量取出所容物。
该发明方法及容器可以实现限量取用或者定量取用， 每次取用的所容物不超过甚 至等于所设定的量。 这有利于提高人们的科学生活水平。

具体实施方式
实施例 1
图 1所示为根据本发明实施例 1所述的一种可以限量取用所容物的容器， 图 2 为图 1的 A部放大图。 容器包括容器主体部分 101和压力加压装置 104。 主体部分由 玻璃或其他透明材料制成， 下部装液体 102， 上部有气体腔 103。 压力加压装置 104 安装在容器主体部分 101的上面， 也就是在气体腔 103的上部， 可以从外部对气体腔 103加压。 另外， 本发明的可以限量取用所容物的容器还包括相邻设置的液体流出通 道 105和气体通道 106， 液体流出通道 105在容器主体部分 101内部的开口位于液体 102的底部（即容器主体部分 101的底部。也可以与主体部分 101—体形成）， 气体通 道 106在主体部分 101内部的开口位于气体腔 103内。 在主体部分 101的外部， 液体 流出通道 105与气体通道 106的壁 107是由柔软材料制成。液体流出通道 105内部设 置可以随液体共同上下移动的移动装置 108。 移动装置 108上有与液体流出通道 105 横截面匹配的单向阀门 109， 阀门 109在加压装置加压时关闭， 无压力或压力较小时 自动向下打开。 移动装置 108与壁 107相邻的位置有向外突出的凸起 110， 使液体流 出通道 105与气体通道 106共用的壁 107向气体通道 106—侧凸起， 凸起 110在气体 通道 106中的位置位于气体通道 106上端封口 111的上部， 使上端封口 111只能随着 移动装置 108移动，阻止其超过移动装置 108向上移动。气体通道 106侧面的开口 113 比液体流出通道 105的出口 112低， 高度差大约为凸起 110的在图 1所示上下方向上 的厚度。 液体流出通道 105外壁上设有可以人工上下移动的标尺 114， 其上有刻度。 在液体流出通道 105与气体通道 106的下部设有可以压縮和拉伸的支撑部件 115， 该部分液体流出通道 105的内径小于移动装置 108的外径， 使移动装置 108始终在支 撑部件 115之上且在液体流出通道 105内部滑动。支撑部件 115环绕在液体流出通道 105与气体通道 106外侧， 由弹性材料制成， 可以拉伸或压縮。 压縮和拉伸的支撑部 件 115， 可以改变移动装置 108的高度位置。 使用时， 将标尺 114上端的零刻度调整 到与主体部分 101内部的液面平齐， 根据需要的体积， 压縮或拉伸支撑部件 115使移 动装置 108的上端与标尺 114上选定体积的对应刻度（下称选定刻度）平齐。接下来， 用加压装置 104加压，使所装液体 102从液体通道 105向外流出。此时，移动装置 108 上单向阀门 109关闭， 移动装置 108随着液体移动。 当移动装置 108移动到液体流出 通道 105的出口 112处， 此时移动装置 108的上端到达标尺 114的零刻度， 气体通道 106上端封口 111随之移动到气体通道侧面开口 113的上部， 气体通道 106与外界接 通， 主体部分 101 内的气体压力降低， 液体流出通道 105液体回流， 本次量取结束， 从而实现量取的体积不超过设定的体积。 当每次量取完成后， 移动装置 108下沉到支 撑部件 115上。
如果每次量取同样的数量且体积较小， 下次使用时可以不必移动液体流出通道 105内的移动装置 108， 只需要向加压装置 104加压就可以完成量取过程。
实施例 2
如图 3所示， 为根据实施例 2所述的一种可以限量取用所容物的容器， 图 4、 图 5为图 3的 A部、 B部放大图。 其为一种盛放粘性液体或者膏体的容器， 包括容 器主体部分 201和一个可以向容器内加压的气囊 202 (相当于实施例 1中的压力加压 装置 104)。 挤压气囊 202可以通过其位于主体部分 201 内部的开口 205向主体部分 201加压。 主体部分 201上部的气体空间有气体通道 203通往流出通道 208的中部， 流出通道 208尾部有吸管 204伸至主体部分 201的接近底部。 吸管 204下部设有单向 阀门 （未图示）， 防止液体或膏体回流。 流出通道 208内部侧壁有一个滑块 206， 滑块 206可以在流出通道 208内部侧壁上设置的滑道 207上滑动。 滑道 207延伸到流出通 道 208的位于主体部分 201的外部的外端开口处。滑块 206上侧面的后部设有长条形 开口 209， 长条形开口 209与气体管道 203相通。 滑块 206其他各面均无开口。 在滑 块 206与所述流出通道 208的内部侧壁之间有不透明薄片 210， 该薄片 210上与长条 形开口 209对应的位置， 有一个小的开口 （未图示）。 通过插拔薄片 210， 调节气道开 口和流出通道 208外端开口处之间的距离。薄片 210与滑块 206以及流出通道 208的 内部侧壁之间气密封， 并可以随滑块 206共同移动。 薄片 210上有刻度显示开口距离 流出通道 208外端开口的长度或该长度对应收容物 （膏体或液体） 的体积。
使用时， 用气囊 202向主体部分 201加压， 压力推动膏体经吸管 204和流出通道 208向外挤出， 也推动滑块 206向外同步滑动。 当滑块 206滑动到上述薄片 210上开 口露出时， 气体通道 203与外界接通， 主体部分 201气体压力下降， 没有向外推动的 压力， 膏体不再向外挤出。 由于流出通道 208内径是一定的， 通过调节滑块 206上薄 片 210的开口位置， 就可以得到确定的每次挤出的膏体体积。 至少， 每次挤出的体积 不会超过设定的量。
滑块 206上安装有复位弹簧 211， 当完成挤出运动后， 滑块 206在复位弹簧 211 的作用下返回流出通道 208内部。
实施例 3
如图 6所示， 为根据实施例 3所述的一种可以限量取用所容物的容器， 图 7为 图 6的 A部放大图。 其为盛放膏体的铝皮容器， 包括容器主体部分 301和加压气囊 305。 主体部分呈管状， 前部 302盛放膏状物如牙膏等， 后部 303有一小段空间为气 体。 前部 302连接流出通道 311， 后部 303连接加压气囊 305。 前部 302与后部 303 之间，设置一个与前部 302内径一致的部件 304，可以将牙膏从后往前挤动。气囊 305 连接一个三通气管， 三通气管包括粗支气道 306和细支气道 307。 其中粗支气道 306 通往后部 303的气体空间。细支气道 307通往流出通道 311内半环状的滑块 308的尾 部， 并与开口 310接通。
滑块 308位于流出通道 311内部上方侧壁， 滑块 308可以在流出通道 311内部侧 壁上设置的滑道 309上滑动。 滑块 308后部与细支气道 307相通， 与流出通道 311内 部侧壁相对的一面有一段纵向长条开口 310， 可以从流出通道 311外插入或拔出的插 片 312覆盖于该开口 310上， 插片 312上与纵向长条开口 310对应的位置有一个横向 开口 （未图示）。 插片 312与滑块 308及流出通道 311 内壁之间均保持气密性。 通过 插拔插片 312， 可以调节横向开口和流出通道 311外端口之间的距离， 以确定需要量 取的膏体的长度或者体积。 插片 312与滑块 308之间设有销栓 （未图示）， 当两者之 间相对位置关系确定后拴上， 使两者共同移动。 当需要量取的体积固定时， 也可以不 设插片， 只需在滑块 308与内壁紧贴一面固定位置上设有不可调节的一个开口。
使用时， 挤压气囊 305， 由于横向开口和流出通道 311外端口不重合， 通往流出 通道 311， 细支气道 307开口被密封。 气体由粗支气道 306向主体部分 301后部空间 加压， 推动部件 304向前移动， 使膏体由流出通道 311出口挤出， 并带动滑块 308共 同移动。 当滑块 308移动到使开口露出的位置时， 气体通道 307与外界接通， 主体部 分 301后部 303的气体空间压力降低， 膏体不再挤出。
当膏体挤出较多后，主体部分 301后部 303气体空间加大，加压时压力上升变慢。 此时可以挤压主体部分 301后部 303， 使其气体空间变小， 便于压力迅速上升。
滑块 308尾部上安装有弹性部件 313， 当完成挤出运动后， 滑块 308在弹性部件 313的作用下返回流出通道 311内部。
实施例 4
如图 8所示， 为根据实施例 4所述的一种可以限量取用所容物的容器， 图 9为 图 8的 A部放大图， 图 10、图 11为活塞 406的状态图。该容器包括主体部分 401、 加压气囊 403和流出通道 402等。 主体部分由硬塑料制成， 上部有开口， 灌装液体后 安装有用以对主体部分 401 内部气体加压的气囊 403。 上部为气体空间 424， 下部为 液体空间 422。 流出通道 402在主体部分 401内部部分位于主体部分 401底部， 呈水 平方向。 流出通道 402内的移动部件， 是由轮圈 404和辐条 405组成的活塞 406。 活 塞 406的上游面 （收容物对活塞施压的一面） 覆盖环形排列的薄片 407， 各个薄片的 朝向中心一端与一根细丝 408—端相连， 另一端与活塞 406上的辐条 405通过滑环 423活动连接， 滑环 423可以在辐条 405上径向滑动约 1/5辐条的长度。 细丝 408另 一端与一个长条滑片 409相连。该长条滑片 409位于主体部分 401上部的气体空间内 壁的滑道 410上， 并可于其上上下滑动。 滑道 410由加厚的固定装置 421固定于内壁 上。 长条滑片 409与主体部分的内壁之间气密封。滑片 409尾部通过弹性部件 411与 内壁固定连接。 滑片 409后部中间位置有一个贯通的开口 412。 主体部分 401沿滑道 410方向与开口 412对应的位置， 依次开设若干个开口 417， 旁边标有刻度。 主体部 分 401外壁沿滑道 410方向设加厚部分 413， 用以使一个长条形卡片 414与主体部分 401外壁压合在一起， 并保持气密性。 长条形卡片 414中间与主体部分开口 417对应 的位置，有一条横向细长的开口 415。长条形卡片 414可以沿滑道 410方向上下移动。 流出通道 402在主体部分 401外部使用柔性管道， 通过支撑架 416支起管道， 当主体 部分 401内液面下降时， 调节支撑架 416的高度， 使管道的内径下缘与主体部分 401 内液面始终齐平。
使用时， 根据需要取出的体积， 移动长条形卡片 414， 使卡片 414的开口 415与 主体部分 401壁上对应刻度旁的开口 417重合。按动气囊 403加压， 薄片 407被挤压 在活塞 406上， 活塞 406被推着沿流出通道 402向外移动， 通过细丝 408带动滑片 409沿轨道 410滑动。当滑片上的开口 412移动到选定的主体部分壁上的开口位置时， 气体通道与外界接通， 主体部分 401内气压下降， 活塞 406不再向前移动。 此时， 流 出的液体体积就是活塞 406推动的液体体积， 也就是刻度显示的体积。 随后， 在滑片 409尾部的弹性部件 411作用下，滑片 409复位，并带动活塞 406向后移动。薄片 407 被提起， 液体充满活塞 406前面的空间， 为下一次使用做好准备。
为了防止流出通道 402外端开口部分受外部灰尘污染， 可以在该开口上方水平安 装一个气袋 419。 气袋 419有管道 420与主体部分气体空间 424相通。 加压时， 气袋 419充气膨胀， 水平伸直， 使流出通道 402开口开放； 压力降低后， 气袋 419在重力 作用下下垂， 挡住该开口， 灰尘被挡在开口外。
加压气囊 403在主体部分 401气体空间 424的开口外可以套有可充气胀大的薄膜 袋 425。 加压时加入的气体都收集在可膨胀的薄膜袋内。 目的是防止加压时加入的气 体与液体空间 422接触造成污染或发生化学反应。此时如果主体部分 401上方气体空 间 424所充的是惰性气体， 则在整个容器的液体取用过程中， 液体都不会与外界气体 接触仅有惰性气体与液体接触。 这有利于更好的保护液体。
薄膜袋 425无回縮性， 可以使每次加压充入薄膜袋内的气体在压力降低后仍留在 薄膜袋内一部分， 在第二次取用所容物时就可以迅速使压力上升， 避免了下次使用时 重复加压。
本实施例的另一个变型是放弃使用长条形卡片 414， 在主体部分 401外壁上的若 干个开口 417旁， 分别设置若干个独立的可以插拔的卡片， 分别独立控制开口 417的 开合。 量取时， 只需拔开对应体积的开口， 插入其他开口上的卡片， 加压， 开口处就 会流出需要的液体体积。
尽管已经示出和描述了本发明的实施例， 对于本领域的普通技术人员而言， 可以 理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、 修改、 替换、 变型和组合， 本发明的范围由所附权利要求及其等同物限定。
