Description

容器封盖
发明领域
本发明涉及一种用于流体容器的塑料封盖，该流体容器在施加手压时通过容器开口而分发产品。
发明背景
用于流体容器封盖的现有技术在设计及结构上有很多。这些封盖常常要求复杂的模制，零件组装，制造费用高，不能完全地关闭及密封，不提供根据用于分发的手压的可变封盖开口，容易在无意的挤压时开启，和/或外形不利于容易的操作及运送。
美国专利第1,977,227号(1934)的现有技术公开了一种封盖，其中面板分别放置于全截头圆锥体(overall frusto-conical)外形内的模具内，然后用橡胶注入面板的上面和下面以在面板之间形成回弹部分。然后在橡胶内切出开启的切口。面板的截头圆锥体外形处于封盖的关闭位置，且面板不能折叠到平的位置以灵活地操作及运送。从而，橡胶不能折叠到封盖的开启或关闭位置，且面板的侧边总是分离的。这种组合的封盖的其它缺点是劳动强度大且制造昂贵。
另一个现有技术公开于国际公开号为WO 82/01360(1982)的PCT专利中，在内部及外部密封件的重叠层中具有三角形面板的复杂配置，或者这种面板的单个层，但在面板间没有相互连接的连结板或膜片或其它密封装置。在后面的例子中，可靠的密封是不可能的，且无意的挤压时的开启是不可避免的。
其它现有技术公知的封盖具有切口构造或各种其它结构。
发明概述
本发明的目的是提供一种塑料单件容器封盖，其坚固地构造，容易且便宜地制造，不要求装配，功能可靠且有效，完全地关闭及密封，根据使用者的手压而提供可变尺寸的封盖开口，没有无意地开启，且由于其形状的优点便于操作和运送。该封盖将用于分发来自容器的洗剂及各种其它流体产品。
封盖具有用于绕其开口附接于容器的环形套环(collar)。多个叶片(leaflets)通过铰链附接于套环，且多个柔性且可折叠的连结板附接于相邻的叶片对上且在相邻的叶片对之间延伸。单个的叶片是硬的平面部件，且用于叶片的各个铰链是线性的，而不是示于序列号为10/920,941的待审专利申请中的曲线弧。叶片在封盖的关闭位置中在基本上平的水平构造中彼此相邻地延伸，且连结板以褶皱折叠于相邻叶片之下。当容器被挤压以分发产品时，叶片在流体压力的影响下在其铰链处向上枢轴转动。叶片向上枢轴转动时彼此分离，且连结板展开且在分离的叶片之间延伸，以与叶片形成封盖分发开口。
叶片的形状是三角形，具有朝向封盖的中心轴线聚集的长边。连结板附接于叶片的长边，且线性铰链附接于叶片的短边。平的(平面的)叶片及直线(线性)铰链有助于提供封盖平滑的开启及关闭。
用于封盖的罩体通过快动作蝴蝶结铰链整体地附接于套环。罩体在其下表面具有中心销，当将罩体关闭于封盖之上时，中心销贴靠于叶片的径向最里面部分而密封。
本发明的封盖及罩体可作为单个部件模制。封盖首先在开口位置模制，叶片有角度地向上延伸且彼此分离，且连结板展开并延伸于相邻的叶片对之间。其后，当叶片和铰链热的时候，向下枢轴转动叶片至关闭的封盖位置，在此处，叶片在基本上平面的表面内彼此相邻地延伸，且连结板在相邻的叶片之下折叠。然后罩体在封盖上关闭，且罩体与封盖自模具移开。接着关闭的封盖及其关闭的罩体可以退火，以中断封盖模制时的开启位置记忆并建立关闭的封盖位置，作为当产品没通过使用者分发时封盖位置的弹性记忆。
本发明的其它特征及优点从下面的描述、附图及权利要求将会显而易见。

实施例详述
参照图1及图2，所示的塑料封盖10具有环形套环11，用于附接到流体容器(未示出)的容器内分发开口的周围。可以通过例如螺纹12(见图3)、卡扣接头(未示出)、或其它已知的附接机构附接。
多个硬的平面叶片13安置在套环11的顶部，且通过整体的线性铰链14(特别见图5)附接于套环11。示出了八个这种叶片13，但是数量可明显地改变。在封盖10的关闭位置，示于图1、图3、图4及图5的叶片13在基本上平的水平表面上彼此紧贴着延伸。每个叶片13是具有两个长边15的三角形，其向远离与特别的叶片13相联接的铰链14的方向聚集。在封盖10的关闭位置，每个叶片13的长边15位于相邻的叶片13的长边附近。每个叶片13的短边25位于与叶片相联接的直线(线性)铰链13附近。
整体地附接于叶片13且在叶片13之间延伸的是多个薄的、柔性的且可折叠的连结板(web)16。各个连结板16在两相邻叶片13的长边15之间延伸且附接于两相邻叶片13的长边15。仅作为例子，连结板16可以为0.005英寸厚的规格，且叶片13可以为0.030英寸厚的规格。在封盖10的关闭位置，各个连结板16在相邻一对叶片13之下折叠，且仅作为例子，相邻的长叶片边15彼此间有比如0.010英寸的间隔。如图2所示，当封盖开启时，长叶片边15将彼此分隔。
例如，封盖10将通常附接于可挤压的流体容器。当容器被手动地挤压，待分发的流体的压力推动叶片13从其于图1基本上平的位置到图2的位置，其中各个叶片绕其铰链14向上枢轴转动，且立刻与其相邻的叶片分开。此刻，连结板16已经展开且在叶片13之间伸直而出。由此在封盖10内造成的分发开口17允许流体产品的分发。容器上较小的手压力会产生较小的开口17，且较大的手压力会产生较大的开口。封盖10的开口情况示于图2、图6和图7中，为清楚地说明，其中一个连结板16没有示于图6中。
在想要的产品量由封盖10分发且解除了挤压压力之后，叶片13会绕其薄的整体的膜片铰链14向后向下枢轴转动，以再次呈现图1的封盖10的关闭状态，连结板16再一次在相邻的叶片13之间和之下折叠。在容器不再被挤压而分发产品之后，通过产品向后吸入进容器内促进了叶片13的向下枢轴转动。
封盖10还包括通过蝴蝶结铰链21整体地附接于套环11的罩体20。罩体20具有自罩体20的下表面(当关闭时)延伸的中心销22及环绕的表面23。蝴蝶结铰链21在封盖10上的罩体20的开启及关闭位置之间卡扣(snap)，且可以为本技术领域内各种已知的快动作(snap-action)铰链设计之一。当罩体20处于关闭位置且叶片13在其基本平的方位上时，在由叶片13的径向向内的顶端19(见图4)限定的封盖的中心轴处，中心销22延伸进中心开口18内。顶端19贴靠中心销22密封。罩体20的下表面23可以在关闭的罩体位置中将叶片13保持平坦。可以为罩体20提供卡扣装置以在关闭的位置上在其外围处卡扣于套环11的外围上。即使容器存在意外的挤压，快动作蝴蝶结铰链21保持罩体20在关闭位置。
套环11、叶片13、铰链14、连结板16、罩体20及蝴蝶结铰链21均可以在单模操作中彼此整体地模制于单件塑料封盖内。例如，塑料可以为聚丙烯。特别地，在单模操作中的封盖的所有部分模制至如图2所示部分的方位。因此，连结板16模制于其展开位置。其后，在铰链14及叶片13仍然热的时候，叶片13向下枢轴转动至图1的关闭位置。连结板16相应地在叶片13下方折叠。然后罩体20向上回转(见图3)并卡扣于封盖11的顶部上，且关闭的封盖10自模具移开。
其后，当封盖10由消费者使用且罩体20开启而通过封盖分发产品时，除了当正在分发产品时之外，期望叶片13及铰链14的弹性位置记忆位于图1的关闭位置。为达到这个结果，在关闭的封盖10上可执行另外的退火操作，在关闭且盖上的封盖10移开模具之后，其罩体还是关闭的。在这种情况下，封盖将在充分的时间内和温度上加热，以建立叶片13及铰链14的关闭的弹性位置记忆。时间和温度将会根据封盖的材料和尺寸变化。之后，当罩体开启时且产品通过图2的封盖分发之后，在产品容器没有被挤压时，叶片接着会自动回复至其图1的关闭位置。
上述的本发明的几个特征共同限定了独特且简单的单件容器封盖，其容易制造，便宜，不要求装配，根据手压提供可变的流量，存在无意的容器挤压时避免了分发，为消费者提供了可靠及有效的功能，便于操作及运送，且如果想要的话，可以在表面上颠倒放置。
本领域的技术人员可以理解本发明可以进行变型和/或改动而不脱离本发明的精神和范围。因此，本实施例认为是示意性的而不是限制性的。应理解说明书中使用的位置术语被使用并意味着与附图所示定位有关，且不另外意味着被限制。
