Description

用于从挤压型产品容器中分配可流动产品的分配闭合件
技术领域
本发明涉及一种用于例如个人护理产品、浓缩饮料、食品、家用和园艺化学产品、保健产品等可流动产品的容器的分配闭合件。更具体地，本发明涉及一种分配闭合件，该分配闭合件具有内部测量储器，该内部测量储器在该容器被倒置时用测定剂量的可流动产品来自动填充、并且在该容器被挤压时从该测量储器分配测定剂量的产品。
背景技术
分配容器被用于各行各业，用于分配各种不同的液体或可流动产品。由于一体化的分配闭合件在所有行业中越来越普遍，消费者希望将其应用于日益扩大的大量产品和包装上，而产品制造商则以尽可能低的成本来寻求独特的解决方案，以促进销售并保持利润空间。
发明内容
本发明涉及一种4件式分配闭合件，用于从挤压型产品容器中分配测定剂量的可流动产品。总体上，产品容器由柔性塑料来模制并且足够柔韧，使得使用者可以容易地挤压容器以向容纳在该容器中的可流动产品施加压力。
该分配闭合件包括闭合体、通过活动铰接件连接至该闭合体的闭合盖、测量储器、可移动地设置在该测量储器内的活塞阀、以及用于将该活塞阀偏置的弹簧。
该闭合体具有上部板、位于中央的出口孔以及流动导管，该流动导管与该出口孔连通、从该上部板向下悬垂以提供从该流动导管的下端处的入口孔到该出口孔的流动路径。该闭合体还包括从该上部板向下悬垂的内安装裙部以及被成形成用于与该产品容器的外部形状融合的外装饰裙部。该内裙部包括用于与该产品容器的螺纹颈部接合的多个螺纹。
杯形测量储器具有底壁、从该底壁向上延伸的圆柱形侧壁以及上周缘，该上周缘以与该上部板的下表面上的安装边沿卡扣配合接合的方式被接纳。该安装边沿环绕该流动导管，使得该测量储器围绕该流动导管。该测量储器具有与该上周缘相邻的多个流动端口，以允许该可流动产品进入该测量储器。在使用时，在该容器被倒置时，该测量储器填充有经过这些流动端口的测定剂量的可流动产品。该底壁还包括多个压力孔口，产品在分配和再填充的过程中移动经过该多个压力孔口。
该杯形活塞阀具有底壁以及从底壁向上延伸的阀杆，该活塞阀在该测量储器内在打开位置与关闭位置之间可滑动地移动。在该打开位置中，该阀杆与在该流动导管的入口孔处形成的阀座间隔开，由此可流动产品可以经过这些流动端口来进入该测量储器并且经过该流动导管离开。在该关闭位置中，该阀杆 与该阀座配对接合，由此关闭该流动导管并且防止该可流动产品离开该出口孔。
螺旋弹簧驻留在该测量储器内，其中，该测量储器环绕该流动导管和该阀杆、并且在该上部板的该下表面与该活塞阀的该底壁之间被捕获。该弹簧将该活塞阀常偏置至其打开静止位置。
在操作中，该活塞阀保持在打开状态下在静止位置处。为了用测定剂量的可流动产品来填充该测量储器，该容器被倒置，其中该可流动产品经过与上部板的下表面相邻的流动端口而进入并且填充该测量储器。该测量储器内的产品现在准备用于分配。通过挤压该容器以在该容器内产生压力来实现该测定剂量的分配。该容器内连续的压力迫使可流动产品经过这些压力孔 口而进入在该活塞阀的该底壁下方的该测量储器、并且迫使该活塞阀从该打开位置朝向该关闭位置移动，并且以此方式经过该流动导管并且离开该出口孔来分配该测定剂量的产品。当该活塞阀到达该关闭位置时，该阀杆与该流动导管的底端上的该阀座相接合以关闭该导管并且完成分配周期。
从该容器中释放压力允许该螺旋弹簧膨胀、并且迫使该活塞阀回到在静止位置处的常状态。该活塞阀的反向运动在该出口孔处引起回吸效应，由此防止任何产品在释放挤压压力后从该出口孔滴落。
可以通过改变该测量储器的尺寸、这些流动端口的尺寸、以及这些压力孔口的尺寸来调整该测定剂量的量。

具体实施方式
现在参照附图，本发明的示例性实施例在图1至图10中总体上用10指示。
本发明涉及一种4件式分配闭合件10，用于从挤压型产品容器14中分配测定剂量的可流动产品12。
总体上，产品容器14由柔性塑料来模制并且具有主体部分16，该主体部分足够柔韧，以使得使用者可以容易地挤压容器14以向容纳在该容器中的可流动产品12施加压力。优选地，容器14还可以包括螺纹颈部18。
分配闭合件10包括闭合体20、通过活动铰接件24连接至闭合体20的闭合盖22、测量储器26、可移动地设置在测量储器26内的活塞阀28、以及用于将活塞阀28偏置至常打开位置的弹簧30。分配闭合件10、闭合盖22、测量储器26和活塞阀28优选地由塑料来模制，而弹簧30则优选地由不锈钢来模制。还可以设想适用于可流动产品的其他材料。
闭合体20具有上部板32、位于中央的出口孔34以及与出口孔34处于流体连通的流动导管36。流动导管36从上部板32向下悬垂，以提供从流动导管的下端处的入口孔38且由其向上到出口孔34的流动路径。闭合体20还包括从上部板32向下悬垂的内安装裙部40以及被成形成用于与产品容器14的外部形状融合的外装饰裙部 42。内裙部40包括用于与产品容器14的螺纹颈部18接合的螺纹。
闭合盖22在关闭位置(图1至图3)与打开位置(图4和图6)之间是可移动的。盖22包括顶壁下侧上的密封结构44，该密封结构以与出口孔34相互配合地接合的方式被接纳以便选择性地防止可流动产品在盖22被关闭时离开出口孔34(参见图6)。
参照图5和图6，杯形测量储器26具有底壁46、从底壁46向上延伸的圆柱形侧壁48以及上周缘50，该上周缘以与上部板32的下表面上的同心环形安装边沿52卡扣配合接合的方式被接纳。安装边沿52环绕流动导管36，使得测量储器26环绕并且围绕流动导管36。测量储器26具有与上周缘相邻的多个流动端口54(在图5中最佳可见)以允许可流动产品流进和流出测量储器26。在使用时，在容器14被倒置时，测量储器26被经过流动端口54的测定剂量的可流动产品来填充。底壁46还包括多个压力孔口56，产品在分配和再填充的过程中移动经过该多个压力孔口。
参照图5至图10，杯形活塞阀28具有底壁以及从底壁58向上延伸的阀杆60，活塞阀28能够在测量储器26内在打开位置(图6和图7)与关闭位置(图9)之间可滑动地移动。为了清晰起见，图7至图10中省略了闭合盖22。在打开位置(图7) 中，阀杆60与在流动导管36的入口孔38处形成的阀座62间隔开，由此可流动产品 12可以经过流动端口54而进入测量储器26并且经过流动导管36离开(参见箭头)。在关闭位置(图9)中，阀杆60与阀座62配对接合，由此关闭流动导管36并且防止可流动产品12离开出口孔34。
螺旋弹簧30驻留在测量储器26内，其中，该测量储器环绕流动导管36和阀杆 60、并且在上部板32的下表面与活塞阀28的底壁58之间被捕获。弹簧30将活塞阀 28常偏置至其打开静止位置(图7)。
在操作中，活塞阀28在静止位置处在打开状态下开始其周期(图6)。为了用测定剂量的可流动产品12来填充测量储器26，容器14被倒置(图7)，其中可流动产品12经过与上部板32的下表面相邻的流动端口54而进入并且填充测量储器26。测量储器26内的产品12现在准备用于分配。通过挤压容器14以在容器14内产生压力来实现测定剂量的分配(图8)。容器14内连续的压力迫使可流动产品12经过压力孔口56而进入在活塞阀28的底壁58下方的测量储器26、并且迫使活塞阀28从打开位置(图7)朝向关闭位置(图8)移动，并且以此方式经过流动导管36并且离开出口孔34来分配测定剂量的产品12。当活塞阀28到达关闭位置(图9)时，阀杆 60与流动导管36的底端上的阀座62相接合以关闭流动导管36并且完成分配周期。
从容器14中释放压力(图10)允许螺旋弹簧30膨胀、并且迫使活塞阀28回到在静止位置处的常状态。可流动产品12经过流动端口54再次进入测量储器26，同时可流动产品12还经过压力孔口56返回至容器14。活塞阀28的反向运动在出口孔 34处引起“回吸”效应，由此防止任何产品12在释放挤压压力之后从出口孔34滴落。一旦被直立，少量的产品12将正常地保持在活塞阀28内。
通过改变测量储器26的尺寸、活塞阀28的尺寸、流动端口54的尺寸以及压力孔口56的尺寸，本领域技术人员可以容易地调整测定剂量的量以及分配和再填充的速度。
因此可以看到，示例性实施例提供了一种分配闭合件10，该分配闭合件对于从挤压型产品容器14中自动分配测定剂量的可流动产品12是特别有效的。
虽然在此示出和描述了体现本发明的不同实施例的某些具体结构，但是对于本领域技术人员来说应明显的是，在不脱离本发明概念的精神和范围的情况下，可以对部件进行各种修改和重新安排，并且除了已经由所附权利要求的范围指示的之外同样不限于在此示出和描述的具体形式。
