具体实施方式
现在参照图1和图2，分别示出根据本发明的一个实施例的容器的主视图和侧视图。如图所示，容器1包括定量分配器10和附接到定量分配器10的容器本体20。用于从容器本体20输送计量剂量的产品的定量分配器10可附接到或坐置在容器本体20上。定量分配器10可用于从容器本体20倾倒期望量的液体或流体以用于各种目的。例如，根据本发明的一个实施例的定量分配器可根据需要用于倾倒期望剂量的洗衣剂、香皂、清洁剂、饮料、调味汁、洗液或者其它产品。在本文中，这些产品被统称为“流体”。虽然定量分配器10和容器本体20可具有图1、2所示的美学外观，但是容易理解，本发明的各个实施例中的定量分配器10和容器本体20的特征可与其它美学外观以及其它特征相结合。
图3和图4是分别示出处于打开状态、闭合状态的定量分配器10的立体图，而图5是处于打开状态的定量分配器10的俯视图。如图所示，定量分配器10包括基部100和附接到基部100的盖子300。盖子300可装配在基部100上且被固定到基部100。盖子300可包括具有活动铰接件304的翻盖部分302，该活动铰接件304将翻盖部分302连接到盖子300的其余部分，使得翻盖部分302可相对于基部出口102打开或闭合，以打开或闭合下文描述的倾倒流体输出流路A和气体通风流路C(参见图9)。翻盖部分302在其面对基部100的一侧可包括内部密封环306，该内部密封环306被构造成与基部出口102相匹配或者密封基部出口102，以在翻盖部分302闭合且内部密封环306坐置 于基部出口102中或者在一些实施例中围绕基部出口102时，帮助防止流体从定量分配器10泄漏出去。例如，在翻盖部分302闭合时，内部密封环306可用于气密地密封基部100的一部分，从而闭合倾倒流体输出流路A和气体通风流路C。在翻盖部分302敞开时，倾倒流体输出流路A和气体通风流路C都暴露于大气环境，如图9所示。
盖子300还可包括窗308，窗308可由清澈透明的、半透明的或者不透明的材料形成，从而允许用户看见流动经过该窗308的计量流体。如图3中所示，窗308被构造为透明的圆弧状凸起，在该凸起的内部限定弧形通道以供计量流体通过。此外，在凸起的两侧可以分别设置两个大体椭圆形的突出部等，这些突出部可被嵌合到基部100的相应部分以用于将盖子300固定到基部100，而且还可以充当显示已经从定量分配器10分配了多少流体的标记。在一些实施例中，窗308本身可标记有刻度或者其它指示物以允许用户判断已经分配的流体的量。
现在转到图6，其示出根据本发明的一个实施例的定量分配器的截面图。如图所示，定量分配器10可包括三个部分：基部100；附接到基部100的插入件200(亦可称为计量插入件)；以及附接到基部100的盖子300。这三个部分均可由例如聚丙烯模制而成。基部100可包括构造成将插入件200和盖子300保留在其中的特征。例如，基部100可包括向上方开口或者向下方开口的嵌入凹槽110，如图所示。插入件200可具有从其底板向上方突出的分隔壁204，该分隔壁204的一部分(即嵌入部206)被嵌入安装到基部100的向下方开口的嵌入凹槽110中。在一些实施例中，插入件200还可以被卡扣配合或者以其它方式装配到基部100中并保持在适当位置，以便于定量分配器10的使用。此外，盖子300可以在窗308的左右两侧端部具有向下方延伸的嵌入凸起312，该嵌入凸起312如图所示被嵌入安装到基部100的向上方开口的嵌入凹槽110中。在一些实施例中，盖子300还可以被焊接或粘附到基部100，以将盖子300固定到基部100。
基部100可包括沿其外周边向下方延伸的周缘部，在该周缘部的内表面上可设置一个或多个螺纹112，从而允许基部100被旋拧到容器本体20的瓶口部的对应外螺纹上(参见图11)。在一些实施例中，还可以使用模塑到基部100中的其它连接元件，诸如卡扣配合元件或卡口部件等，用于将基部100连接到具有对应元件的容器本体20。基部100还可以包括向下方延伸且与前述周缘部间隔开的接合凸缘114。插入件200的外周边与接合凸缘114的内表面接合，而容器本体20的瓶口部则被接纳在由接合凸缘114的外表面与前述周缘部限定的间隙中。在一些实施例中，定量分配器10还可以包括垫圈400，其坐置于基部100内且位于基部100的内壁与容器本体20的上部之间，而且位于基部100的周缘部与接合凸缘114之间，以用于相对于基部100来密封容器本体20。垫圈400例如由发泡聚乙烯制成，并且容易从市场上购得。
如图所示，基部100包括倾倒流体通道104和计量流体通道106，它们分别与设置于插入件200中的第一开口208、第二开口210流体连通，如下文所述。当从附接至定量分配器10的容器本体20倾倒出流体时，容纳于容器本体20内部的流体可流动通过倾倒流体通道104和基部出口102而离开定量分配器10。同时，一部分流体将作为计量流体流动通过计量流体通道106和设置于盖子300中的弧形通道310。在一些实施例中，设置于盖子300中的计量流体流路完全由弧形通道构成，当然也可部分地由弧形通道构成。由此，离开计量流体通道106的计量流体立即冲撞到弧形通道310的弧形壁上，被该弧形壁引导而沿着弧形通道310流动。
基部100还可包括导向件108，用于引导离开弧形通道310的计量流体全部通过设置于插入件200的第三开口212，如下文所述。在一些实施例中，导向件108可充当弧形通道310的一部分壁而与盖子300的窗308共同限定该弧形通道310的至少一部分。可选地，弧形通道310也可以仅仅形成于盖子300的窗308中，在上游端具有与计 量流体通道106连通的入口，并在下游端具有面对第三开口212的出口。在此情况下，围绕弧形通道310的出口的通道壁被构造为导向件。容易理解，弧形通道310也可以被替换成具有其它截面形状的通道，只要它能够连通计量流体通道106与第三开口212即可。
在图7至图8中示出根据本发明的一个实施例的定量分配器中的插入件的具体构造，其中图7示出该插入件的从底部观察的立体图，图8示出该插入件的从顶部观察的立体图。如图所示，插入件200从基部100的下方被嵌入安装到基部100中。具体而言，插入件200的分隔壁204的嵌入部206被嵌入到基部100的向下方开口的嵌入凹槽110中，并且插入件200的外周边与基部100的接合凸缘114的内表面接合。在一些实施例中，插入件200可具有沿着其外周边从大体平坦的底板202向下方突出的凸缘。该凸缘的外表面与基部100的接合凸缘114的内表面接合，以增大它们之间的接触面积并提高固定效果。在一些实施例中，该凸缘可具有比接合凸缘114的内径稍大的内径，从而在插入件200与基部100之间形成过盈配合。
插入件200还可包括从其底板202向上方突出的分隔壁204、以及构造成穿过底板202的第一开口208、第二开口210和第三开口212。分隔壁204包围第二开口210，并且将第二开口210与第一开口208和第三开口212隔开。第二开口210被设置在由分隔壁204限定的内部空间内，而第一开口208和第三开口212被设置在分隔壁204的外部。如图所示，分隔壁204从左到右大体上包括从底板202向上方突出的第一区段、第二区段、第三区段和第四区段。第一区段的上边缘与底板202的表面平行。第二区段的上边缘与底板202的表面平行，并且具有比第一区段的高度更高的高度。第三区段的上边缘具有从左到右逐渐减小的高度。第四区段的上边缘与底板202的表面平行，并且具有比第三区段的右端处的高度更低的高度。插入件200的第二区段和第三区段构成了前述嵌入部206，该嵌入部206被插入到基部100的嵌入凹槽110中而将插入件200固定至基部100。第四区段的上边 缘与第三区段的上边缘之间的间隙形成了后述的气体通风流路C(参见图9)的一部分。
在一些实施例中，插入件200可包括从分隔壁204径向朝外延伸且从底板202向上方延伸的分隔片，以进一步将第三开口212与第一开口208隔开，从而将倾倒流体输出流路A与计量流体返回流路B和气体通风流路C隔离开。在一些实施例中，插入件200还可以包括一个或多个第四开口214。第四开口214由分隔壁204包围，并且在定量分配器10的操作期间和之后允许空气或气体流入到容器本体20中以对容器本体20的内部通风。在图8所示的实施例中，两个第四开口214设置在由分隔壁204包围的底板202的部分区域上，相对于连接底板202中心和第二开口210中心的直线而处于对称的位置。可选地，还可以在这条直线上设置仅仅一个第四开口214(参见图12)。
如图7至8中所示，一个第二开口210设置在底板202的大体中央位置，两个第一开口208大体对称地设置在第二开口210的两侧。连接两个第一开口208的中心的直线与连接底板202的中心和第二开口210的中心的直线彼此垂直。在一些实施例中，可以设置仅仅一个第一开口208或者多于两个第一开口208，也可以设置两个或更多的第二开口210。第一开口208被构造成与基部100的倾倒流体通道104流体连通，从而在定量分配器10处于分配位置时，允许倾倒流体从容器本体20的内部流出，继而通过插入件200并流到基部100的倾倒流体通道104中。第二开口210被构造成与基部100的计量流体通道106对准，从而在定量分配器10的操作期间，允许计量流体从容器本体20的内部流出到基部100的计量流体通道106中。
每个第一开口208的直径或面积可基于流体特性和系统的期望流动特性予以调整。每个第二开口210的大小、直径或面积也可以针对待分配的特定流体而变化或改变。以此方式，定量分配器10可以通过仅改变一个部分(即，插入件200)来用于具有不同特性(诸如粘性)的流体的各种应用。在一些实施例中，第二开口210的大小、直径或面 积可被选择并且模塑或成形为提供流体到计量流体通道106中的恒定流量，从而在操作期间获得窗308的恒定填充，进而允许用户测量从定量分配器10分配的流体量。此外，第一开口208和第二开口210可被确定相对位置和尺寸，使得在从容器本体20中倾倒出流体时，经由第一开口208流过倾倒流体通道104的流体量与经由第二开口210流过计量流体通道106的流体量成固定的比例。基于这种固定的比例，可以在盖子300的窗308上设置刻度或其它指示物，由此准确地指示已经通过倾倒流体通道104从定量分配器10分配了多少流体。在一些实施例中，这种刻度或其它指示物可基于插入件200和从定量分配器10倾倒的流体被构造。例如，基于待分配流体的特性和插入件200的各个开口的大小，盖子的窗308部分将以给定速率或相当恒定的速率被填充。这允许在窗308上包含标记，以指示在给定时间量内有多少流体已经从分配器流出。
此外，第一开口208和第二开口210可包括阻挡元件216，以限制流过这些开口208、210的流体的流速。如图8所示，阻挡元件216具有从插入件的底板202向上方突出的柱状凸台218、从柱状凸台218沿径向朝内延伸的一根或多根肋条220、以及经由肋条220连接到柱状凸台218的挡块222。柱状凸台218可具有大体圆柱形的形状，挡块222也可相应地具有大体圆形的形状。多个彼此间隔开的肋条220连接着柱状凸台218的内周边和挡块222的外周边，并且可由例如弹性材料制成。当从容器本体20倾倒出流体时，容纳于容器本体20内的流体首先流过第一开口208和第二开口210。由于挡块222的存在，流体在流过第一开口208和第二开口210时，其流速会减缓。具体而言，倾倒流体首先会流过第一开口208处的阻挡元件216的多个肋条220之间的空隙，而计量流体首先会流过第二开口210处的阻挡元件216的多个肋条220之间的空隙。在流体以较慢的速度流过第一开口208和/或第二开口210时，设置于窗308上的刻度或其它指示物能够更准确地指示在给定时间量内已经从分配器流出的流体量。
在一些实施例中，肋条220从柱状凸台218的内周边朝下方倾斜，使得挡块222位于柱状凸台218的上边缘的下方。在此情况下，若肋条220由弹性材料制成，则流出流体的冲击效应会导致挡块222向上方位移，使得柱状凸台218与挡块222之间的流路面积减小，从而进一步限制流出流体的流速。流体的流出速度越快，流路面积减小得越多，因此能够自动地调节通过第一开口208或第二开口210流出的流体速度。可选地，肋条220也可从柱状凸台218的内周边朝上方倾斜，使得挡块222位于柱状凸台218的上边缘的上方。
在一些实施例中，阻挡元件216可以设置在第一开口208和第二开口210的任何一个中。例如，阻挡元件216可以设置在两个第一开口208中或者仅仅一个第一开口208中，也可以仅仅设置在第二开口210中。在一些实施例中，阻挡元件216能够可拆卸地安装到各个开口208、210，并且能够根据待分配流体的特性而进行更换。如图8所示，设置于第二开口210处的阻挡元件216的柱状凸台218在内侧具有向下方凹入的大体圆柱形的台阶部。该台阶部抵靠基部100的计量流体通道106的下部(参见图6)，使得当从容器本体20中倾倒出流体时，流过第二开口210的计量流体不会泄漏到由分隔壁204限定的内部空间中。
图9示意性地显示各种流体在定量分配器内的流路，例如分别用虚线、一点画线和两点画线表示计量流体返回流路B、倾倒流体输出流路A和气体通风流路C。如图所示，倾倒流体输出流路A由设置于插入件200的第一开口208、基部100的倾倒流体通道104和基部出口102的一部分限定而成。计量流体返回流路B由设置于插入件200的第二开口210、基部100的计量流体通道106、设置于盖子300的窗308中的弧形通道310和设置于插入件200的第三开口212限定而成。此外，气体通风流路C由基部出口102的一部分、被插入件200的分隔壁204限定的内部空间和设置于插入件200的第三开口212限定而成。在第四开口214被设置在由分隔壁204包围的底板202上的 情况下，气体通风流路C还可包括从前述内部空间通过第四开口214的支路。
下面描述根据本发明的上述定量分配器的工作原理。具体而言，在具有附接至其的定量分配器10的容器1倾斜以从容器本体20中通过定量分配器10倾倒流体时，流体通过插入件200，离开基部100的倾倒流体通道104且进入计量流体通道106。流体在流入计量流体通道106中时会缓慢地移动通过盖子300的窗308部分，从而允许用户看见流体的流动并由此测量已经从定量分配器10倾倒出的流体的量。当流体从定量分配器10流出时，用户可观察窗308，并且在流体已经达到他们希望从分配器分配的指定部分时，停止倾倒。紧接着，用户可将容器1旋转到正面朝上，此时位于盖子300的窗308部分中的流体将通过插入件200的第三开口212流回到容器本体20中。
在定量分配器10的操作过程之中和之后，空气或其它气体可通过基部出口102的一部分进入由插入件200的分隔壁204限定的内部空间，并且流动越过分隔壁204尤其是分隔壁204的前述第四区段，继而通过插入件200的第三开口212。如图9所示，基部的导向件108与分隔壁204间隔开，因而流动越过分隔壁204的气体经由分隔壁204与导向件108之间的间隙而流向第三开口212。这样的气流有助于迫使从设置于窗308中的弧形通道310流出的计量流体偏离分隔壁204，从而避免这种计量流体进入到前述内部空间或者基部100中的倾倒流体通道104。结果，能够获得与已经从分配器流出的流体量有关的更精确指示。在将上述分隔片设置于第三开口212与第一开口208之间的情况下，朝向第三开口212流出弧形通道310的计量流体将不会与流出第一开口208的倾倒流体发生干涉，从而能够获得与已经从分配器流出的流体量有关的更精确指示。
现在参照图10至图13，具体描述根据本发明的另一实施例的定量分配器，该定量分配器不包括如上所述的阻挡元件216。具体而言，如图10所示，该定量分配器10的基部100包括计量流体通道106和 倾倒流体通道104，容器内的产品可从倾倒流体通道104倒出分配器。基部100中的通风路径(未标出)可允许来自大气环境的空气进入定量分配器10以用于通风的目的。
图12示出定量分配器的俯视图，图13示出该定量分配器的截面透视图。如图所示，插入件200包括至少一个第一开口208(亦可称为产品入口)。在一些实施例中，在插入件200的主体中可形成至少两个第一开口208。第一开口208被构造成在定量分配器10处于分配位置时，允许产品从容器1的内部流出通过插入件200并流到倾倒流体通道104中。如上所述，每个第一开口208的直径或面积可基于产品特性和系统的期望流动特性调整。这样，定量分配器10可通过仅改变一个部分(即，插入件200)来用于具有不同特性(诸如粘性)的液体的多种应用。插入件200还可以包括一个或多个第三开口212和第四开口214。开口212、214可在定量分配器10的操作过程之中和之后允许空气或气体流到容器1中以使容器1的内部通风。此外，插入件200还可包括一个或多个第二开口210(亦可称为计量入口)。第二开口210可与计量流体通道106对准，以在定量分配器10的操作期间，允许产品从容器1的内部流到计量流体通道106中。第二开口210的大小、直径或面积可针对待分配的特定产品变化或改变。
在该实施例中，当具有分配器的容器倾斜以从容器通过分配器倾倒产品时，产品通过插入件200离开倾倒流体通道104且进入计量流体通道106。产品在流入计量流体通道106时会缓慢地运动通过盖子300上带有窗308的部分，从而允许用户看见产品的流动并测量已经从定量分配器10倾倒的产品的量。当产品从定量分配器10流出时，用户可观察窗308，并在其已经达到他们希望从分配器分配的指定部分时停止倾倒。另一方面，在定量分配器10的操作过程之中和之后，空气或其它气体可通过基部中的通风路径进入由插入件200的分隔壁限定的内部空间，并经由第四开口214进入到容器本体20中(参见图11)。容易理解，空气或其它气体还可以流动通过基部的导向件108与 分隔壁204之间的间隙，继而经由第三开口212进入容器本体20中，如上文所述。
根据本发明的上述各个实施例，定量分配器可定制成用于特定的流体，使得该分配器可被构造成带有插入件或与插入件组装在一起。插入件具有计量入口(即，第二开口210)，其被构造成限制流体到定量分配器的窗中的流动，使得用户可判断或测量从分配器分配的产品的量。在一些实施例中，计量入口可具有阻挡元件以减小流体通往定量分配器的窗中的流量，使得用户能够更加准确地计量从分配器分配的流体量。插入件还具有倾倒入口(即，第一开口208)，以便从容器中倾倒流体。在一些实施例中，一个或多个计量入口和一个或多个倾倒入口可被构造成使得流动通过倾倒入口的流体量对应于流动通过计量入口的流体量，使得用户可以在视觉上在窗中看见该流体量，该窗可包括标记以显示已经从分配器分配了多少流体。例如，倾倒入口的直径可以与计量入口的直径成比例，使得对于特定流体特性，能够基于通过计量入口的流体流动限定该比例并设置直径，以监视通过分配器的流体流。
虽然已经这样描述了本发明的某些具体实施例，但是应当理解通过所附权利要求限定的本发明不受限于在上述说明书中所陈述的具体细节，因为可预期其许多显而易见的变型。相反，本发明仅被所附权利要求限制，所附权利要求包括在其范围内的根据如所述的本发明的原理操作的所有等效装置或方法。
