Description

具有计量输送的流体分配装置
相关申请案的交叉参考
本申请案主张基于2004年3月10日递交的第60/551,993号美国临时申请案的优先权。
技术领域
本发明一般来说涉及分配装置和封装。更具体地说,本发明涉及计量装置,其能够从流体介质源可控制地分配流体介质。
背景技术
各种类型的流体材料和介质被用于商业和工业中的不同目的。举例来说,在个人护理、家庭护理、空气护理、运输护理和食品工业中存在需要从流体材料源进行某一类型的流体材料分配的各种产品。当市售此材料时,其必须容纳并存储在某一类型的容器中。当使用所述产品时,其必须从其存储容器分配到一位置以供使用。
在现有技术中,存在用于输送流体材料的很多不同类型的分配。举例来说,通常为此目的而提供一具有喷嘴尖的柔性容器体。此类使用的一应用是用于分配调味蕃茄酱,其中用户挤压容器体以迫使流体材料从喷嘴尖出来且准确地到达一所要位置。所输送的流体量由用户挤压容器体的程度来确定。然而,这产生不稳定结果,其中每次连续挤压容器体时输送出不同量的流体材料。同样,因为没有采用阀,所以必须保持容器直立以避免泄漏。
在现有技术分配装置的另一实例中,一柔性容器保存有大量待输送的流体材料。提供单个单向止回阀以作为柔性容器的出口。当挤压柔性体时,材料在压力作用下被迫使穿过阀而出来。
还需要不仅分配流体材料,而且有助于将它们施加(诸如)到一表面。在现有技术中,为此目的,可挤压容器体已经装备有某一类型的施料器头。举例来说,在个人护理产业中,身体清洗装置通常包括某一类型的可挤压容器体和一施加于其上的研磨施料器材料(诸如织物或泡沫)。因此,当流体材料出现在容器体外部时,施料器通过散布在施料器内的流体来参与将材料散布在用户身体上以使其更好且更均匀地分布。在个人护理产业(诸如鞋油)中,施料器对于均匀分布来说特别有用,以确保优质均匀且光滑的涂覆。
在现有技术中已经尝试提供一分配器,其可容易地将流体材料输送到一环绕容器体的施料器。这些现有技术装置采用(例如)弹簧承载按钮,其打开主容器体中之出口以允许流动到一外施料器材料层。这与要求用户挤压容器的整体大不相同。然而,这些装置不能够在每个分配操作时输送出大体上相等剂量的流体,因为它们仅仅打开容器体且允许流体在重力作用下流动到施料器材料。结果,流体材料必须在容器下侧引出。因此,不可能在容器的一个以上侧上或在与重力方向相反的方向上分配流体。为了在不考虑重力的情况下分配流体材料,在现有技术中必须采用可挤压容器体,其具有上文所述的所有缺点。
鉴于前面描述,现有技术的流体分配和装置遭受各种缺点,使得它们难以且不便使用并具有意外结果。因此,需要一种易于操作的流体分配器。此外还需要流体分配器能够在每次分配操作时输送出一计量剂量的流体,以获得预期流动以便更好地施加流体材料。还需要此类分配器为重力无关的。另外还需要流体能够被输送以在容器表面上任一点处引出。根据需要,此外还需要分配器包括一施料器材料以均匀分布并均匀施加流体材料。
发明内容
本发明保留现有技术分配装置的优点。另外,本发明提供当前可用装置中未发现的新优点且克服此类当前可用装置的很多缺点。
本发明一般来说针对一种新颖且独特的分配器,其用于在每次分配操作时输送出一大体上相等计量剂量的流体材料且具有一可选施料器以便均匀分布所分配的流体材料。
所述流体分配装置包括一其中具有一内部流体存储区域的容器。一柔性计量外壳被设置成与所述流体存储区域形成流体连通,其中一第一单向阀设置在所述容器与所述柔性计量外壳之间。当按压且接着释放所述柔性计量外壳时,来自容器的内部流体存储区域的单向流通过真空作用使计量腔室的预定容积充满流体。一第二阀与计量外壳输出口形成流体连通,且在再次按压计量外壳时允许从计量腔室到容器的外部外区域的单向流体流动。每当按压计量外壳时,都从容器中分配出一大体上相等体积的流体。一位于容器外侧上的额外泡沫层有助于分配和输送流体。
因此,本发明的一目的在于提供一种流体分配装置,其可从每次分配操作中输送出一大体上相等体积的流体材料。
本发明的一目的在于提供一种不受重力影响的流体分配装置。
本发明的又一目的在于提供一种流体分配装置,其包括一施料器以确保均匀输送流体材料。
本发明的另一目的在于提供一种流体分配装置,其可从所述装置在任一点处输送流体流。
本发明的又一目的在于提供一种流体分配装置,其可从所述装置在多个位置处输送流体流。

具体实施方式
首先参看图1和2,本发明的分配装置10经绘示为包括一外覆盖物(通常称为12),其充当一施料器材料。此施料器材料12可由适合即将到来的应用的任何类型的材料形成。举例来说,如图1和2中所见,覆盖物12优选由两种不同类型的材料12a、12a形成以便在使用中用于两种目的。优选地,顶部部分12a由泡沫材料制成,而底部部分12b由网孔或“浴棉”材料制成。顶部部分12a可通过(例如)熔接而固定到底部部分12b。如将结合图3更详细地描述,一搭扣配合覆盖物14密封一加料口16。还可提供一挂带或绳18。施料器12的配置仅仅是下文将更详细地论述的本发明的很多不同类型施料器中的一种。
现在转向图3,其绘示穿过图1的线3-3的截面图,以说明本发明的分配装置10的内部构造。提供一容器体20,其包括一流体存储区域22,所述流体存储区域22中含有大量流体材料24。所述容器20优选地由柔性材料(例如塑料或尼龙)制成。因此,随着流体材料24从容器体20内排出,其将逐渐塌陷成一紧凑结构。
在容器体20的第一开口28处提供一计量外壳26。所述计量外壳26包括一吸入单向阀30(诸如一止回阀),以将流体24从容器体20的流体存储区域22吸引到具有一预定尺寸的计量腔室32中。任何类型的阀都可用于匹配给定应用。吸入阀30安置于计量外壳26的底板34中。因此,流体24仅可从流体存储区域22单向流入计量腔室32中。计量腔室32由一呈按钮或球状物形式的柔性膜片36界定,所述柔性膜片36可通过施料器材料12中的间隙38来接近或操纵。按钮36优选为透明的,以当经计量剂量的流体材料24准备好被输送时向消费者提供指示。
提供一输出阀40,使其与计量外壳26的计量腔室32形成流体连通。因此,驻留在计量腔室中的流体仅可通过输出阀40引出。同样,还提供一流体导管42以引导流体24在任一位置处穿过容器体而引出。优选地,如图3中所见,所述流体导管42将计量外壳26的输出阀40连接到一位于容器体底部上的出口44。这允许计量外壳26位于与流体24穿过其而引出的侧相对的侧上。取决于即将到来的应用,流体导管42可经引导并定位以在任一点处穿过容器体20引出。同样,作为取决于应用要求的一替代方案,输出阀40可位于出口44处。
仍参看图3,进一步阐释分配装置10的操作。按压计量外壳26的按钮36以起始一真空操作。更具体地说,当进一步释放按钮36时,流体24从容器体20的流体存储区域22被吸引到计量腔室32中,所述计量腔室32经配置以具有一特定已知容积。释放按钮36的动作将计量腔室32填充到实质容量。因此,在计量腔室32内含有一经计量的量的流体材料24以为输送作准备。可根据待分配的流体材料24的类型和为此的应用以及所要剂量体积来选择计量腔室32的尺寸。
按钮36的进一步按压迫使计量腔室32内的经测量体积的流体24穿过计量外壳26的输出阀40而引出。接着,此已知量的流体材料24直接传送到施料器12以供使用,或如图3中所见,穿过流体导管42以更有目标地引入到施料器12中。在此情况下,所述计量体积的流体材料24优选地被传送到容器体20底部,以分配到在其底部表面上的施料器部分12b中。举例来说,此配置尤其非常适用于分配身体洗涤剂以用于沐浴目的。其它应用可能需要不同的引出和引入位置以进入施料器材料12。
在图4中,绘示具有经修改的计量外壳126的容器120的替代构造。在此实施例中,一输出阀阵列128径向地安置于环绕计量外壳126的外围处,以将流体材料124直接输送到其相同侧上的施料器材料(为了便于阐释,图4中未绘示),而不采用途径容器体20内部的流体导管42。此径向输送图案非常适合用于需要围绕计量外壳同时分配内容物的施料装置中,例如用于施加润肤乳。
另外,图5说明本发明的具有经修改的计量外壳226的容器220的另一替代构造,其中一输出阀阵列228线性地安置于容器体220的顶部表面上,以将流体材料直接输送到其相同侧上的施料器材料(为了便于阐释,图5中未绘示),而不采用流体导管。此线性输送图案非常适合用作沿装置的纵轴以基于线性冲程方式来施加流体的施料器。
根据本发明,可容易地修改流体材料24的输送方向,以匹配即将到来的施料。在特定应用中,需要位于容器体20的顶部和底部上的施料器材料12以均匀分布的方式来接收流体材料。如上文所示,可从容器20上的任一位置导出流体材料24以根据需要来输送流体。常常需要流体24能够被动地从容器20的一侧20a流动到容器20的相对侧20b,尤其是在其边缘20c处。
回头参看图1,制造一优质分配装置10的有效方法在于采用热熔接来构建容器20和其上的施料器材料12。举例来说,顶部部分20a通常环绕其外围20c而热熔接到底部部分20b,以形成一其中具有一内部流体存储区域22的容器20。施料器材料12类似地环绕其外围或其与容器20的整个接触表面通过热熔接或其它类似工艺(例如胶合)而固定到容器20。
如果采用环绕容器20的外围20c的热熔接接缝20d,那么其将减少一侧上的施料器材料12a中的流体24对另一侧上的施料器材料12b的流动和毛细作用,且反之亦然。因此,流体24必须行进越过容器的接缝20d和施料器材料12的接缝12d以出现在相对侧上。此接缝12d、20d阻止流体24自由地从容器20的前部流动到后部,且反之亦然。
图6说明本发明范畴内的容器20的修改,以解决上文所指出的问题。  更具体地说,在容器20的外围边缘20d中形成若干凹口46,以允许流体材料24容易地从容器20的一侧流动到另一侧。当在其外围边缘处将施料器材料12热密封到容器以形成一接缝12d时,在接缝20d、12d与施料器材料12之间形成若干贯通孔48,以允许流体材料24从装置10的一侧自由地行进到另一侧和后部,而无须行进越过外围接缝12d、20d。
现在转向图1、7和8,其详细绘示对计量外壳26构造的进一步增强。如图1和7中所见,若干支立腿50从计量外壳26的底板34向下伸出。这些腿50防止底板34完全降到最低点并阻碍流体材料24流入吸入阀30中。当留在容器20中的流体材料24的体积变低且容器20在配置上变得相对扁平时,所述支立腿50尤其有用。在此情形下,有可能发生前述的降到最低点的情况。然而,使用图1和7的支立腿50防止这种情况发生。
回头参看图1,图8说明计量外壳26的另一修改,以确保达到最大吸入且在每次按压和释放按钮36时都填满整个计量腔室32。一弹簧偏置结构52驻留在计量外壳26的按钮或球状物结构36内。因此,按钮36快速恢复且同时提供一强劲吸力或真空以使计量腔室32内部填满所要计量体积的流体材料24。所述弹簧偏置结构52优选采用一螺旋弹簧,但其它弹簧偏置结构,诸如叶板弹簧和泡沫材料,也可用于此目的。
图9说明本发明的另一替代实施例300,其中诸如容器220或120的容器包括从容器220向外伸出的一系列突出部302。一外框架或骨架304经由突出部302连接到容器220。接着将诸如“浴棉”或织物材料的施料器材料306附接到框架304,其中容器220驻留在其中。此实施例300尤其非常适用于允许流体材料环绕分配器300自由流动。
本发明的分配装置10具有对于利用本发明的独特计量剂量能力有用的一大批应用。实际上,具有任何类型的施料器材料或以不同配置的施料器材料的组合的任何分配器都可采用本发明。
举例来说,个人护理产业在受控或计量分配盆浴或淋浴露中具有特别应用。同样,药品、化妆品、护发产品(诸如洗发水)、护肤产品(诸如护肤液)、驱虫剂和防晒产品可采用本发明。
同样,各种家用产品可在根据本发明的装置10中输送。这些产品包括用于家具清洁和打光、浴盆和淋浴间清洁、地板清洁和打光、窗户清洁、除臭、灶具清洁、洗衣房清洁和服装处理的产品。同样,空气处理装置可采用本发明。
另外,可以受控方式来分配清洁产品,诸如用于清洁汽车、自行车、飞机和卡车的那些产品。食品工业具有大量潜在应用,尤其对于分配调味品、调味汁和维生素而言。
为了采用本发明的分配装置10,可容易地修改计量外壳26的尺寸和构造以及流体材料24在何处被输送到装置表面的定位以匹配给定应用。用于容器20和计量外壳26的材料虽然优选为柔性塑料,但可为适于即将到来的应用的任何材料。同样,容器20与计量外壳26可由不同材料制成。
最重要的是,为匹配给定应用所作的本发明修改尤其涉及施料器材料12本身的性质和配置。
施料器材料12可为泡沫(诸如开孔泡沫)、织物、混合材料、复合材料和其组合。应了解,这些材料仅仅是可与本发明的分配器10一起使用的多种类型的材料的实例。具体材料由给定应用和待分配的材料的类型来确定。
因此,当流体材料24在泡沫内分配时,流体24将趋向于通过将水分从高水分点移动到水分点来平衡水分。此毛细作用使得流体24自然地传播通过施料器材料12。由于在外围处不存在施料器材料12,所以图6的凹口46和贯通孔48有助于装置10的一侧对另一侧的毛细作用(如果在所述应用中有必要的话)。
非编织材料或纤维也可用作为用于在装置的一侧或两侧上的施料器12的材料。举例来说,还可采用网状泡沫。这些材料将非常适合用作为其中需要韧性的施料器12,以用于诸如轮胎清洁剂和脱漆剂的更粗糙的化学品。
同样,举例来说,可在装置的一侧上提供更多研磨材料以更强烈地清洁,而相对侧具有一抛光类型表面。
通常,可修改网眼的尺寸、密度和毛细作用以及施料器12的总尺寸以匹配待施加的特定流体。
总之,提供一新式且新颖的分配器10,其可输送稳定计量剂量的此类流体材料24。分配器10具有一大大改良的构造,其中流体材料24均匀分布在整个施料器材料12上,以更高效率且更有效地分配流体。
