背景技术
在现有技术中,具有饮用嘴和与之分离的气口的杯使使用者在从饮用嘴饮用时不会在杯中形成过度的真空。然而,在喂送之间或者在使用中如果掉落,饮用嘴和气口容易泄漏存贮在杯中的液体。因此,已经发展出几种在饮用嘴和气口使用阀门控制机构的杯。在喂送时这些阀门响应于抽吸作用而打开,允许液体流过饮用嘴,并且在杯内部形成真空时允许空气进入气口。

优选实施例的描述
参照附图,尤其是图2到图4,本发明的饮用杯组件总体用参考标号10表示。组件10包括一个杯12,一个盖14和一个流量控制阀门20。盖14用于密封杯12,除了在其表面中形成的饮用嘴16和气口18中的孔之外。流量控制阀20与饮用嘴16和气口18连通,以形成基本上防泄漏组件10。
盖14形成有配合表面,优选是与饮用嘴16和气口18接近或结合在饮用嘴16和气口18中,其目的是与流量控制阀门20摩擦接合,并且将流量控制阀门放置成与饮用嘴16和气口18流体连通。在图2所示的实施例中,盖14在其饮用嘴16中和气口18下方形成有圆柱形凹槽17。这些凹槽17作成能够接收流量控制阀门20的构造。
在图3到图5所示的实施例中,流量控制阀门20包括两个竖管24。竖管24包括下部26、上部28和阀门表面30支承的缝隙32。这些竖管24适于压入凹槽17中,以便将流量控制阀门20摩擦配合于盖14中。因此,当凹槽17具有一个下圆柱部时,这是较优选的,竖管24的下部26的形状较优选的也基本上是圆柱形的。
如图3和4所示,各竖管24是细长的。另外,各竖管24具有特殊的直径并具有基本相等的高度。竖管24的细长形状使它们将阀门表面30和缝隙32(见图5)放置在非常靠近饮用嘴16和气口18中的孔的地方。竖管24的直径允许较大的、相对不受限制的流体流到缝隙32的区域。已经发现,这种设置提供了需要打开缝隙32的抽吸和流体流过缝隙之间最佳的平衡。
类似地,其基本圆柱形的直径和形成的内部轮廓产生了一种简单、宽开口和管,以便在使用后能够彻底地清洗竖管24,并减小干燥的或冻结的液体可能沉积其中的场所和边角的数量。竖管24的外轮廓较优选地作成台阶状,如图3和4所示,但是竖管的内轮廓可以是恒定的直径或恒定地缩小的直径,这样形成一个光滑的、没有台阶的内表面。较优选地,所述光滑内表面或者是圆柱形的,截头圆锥形的,或者是两者的组合。这种光滑的内表面进一步增强了流体的自由流动,并且使竖管24易于清洗。对于组件10的正确和卫生地发挥作用以及对于消费者接受阀门来说,上述优选的流量控制阀门20易于清洗是非常重要的。
已经发现,阀门表面30优选的凹进形状以及伴随的缝隙32的弯曲形状提供了比现有阀门构造较好的流过缝隙32的流体流速。这使得组件10更容易饮用,较少破坏和麻烦使用。另外,已经发现,细长的单个缝隙32最好是横切口或者其它类型的穿过阀门表面30的孔。较优选地,缝隙32基本上从凹进阀门表面30的边缘延伸到边缘。
最优选的,与饮用嘴16对齐的阀门表面30的曲率半径大约为6.78mm。与气口18对齐的阀门表面30最优选的曲率半径大约为6.78mm。与饮用嘴16对齐的缝隙32的最优选的长度大约为5.96mm。与气口18对齐的缝隙32最优选的长度大约为4.31mm。与饮用嘴16对齐的竖管24最优选的内径从大约7.65mm到大约9.34mm,较理想地是具有前述最小和最大直径的截头圆锥形状。与气口18对齐的竖管24最优选的内径从大约6.4mm到大约9.34mm,较理想地是具有前述最小和最大直径的截头圆锥形状。与饮用嘴16对齐的竖管24最优选的高度从顶部到底部大约为20.39mm,从凹痕到底部大约为13.23mm。与气口18对齐的竖管24最优选的高度从顶部到底部大约为18.54mm,从凹痕到底部大约为13.97mm。两竖管24对中心的距离优选为40.64mm。与饮用嘴16对齐的竖管24的下部26的优选外径大约为13.25mm。与气口18对齐的竖管24的下部26的优选外径大约为11.60mm。这些尺寸使之与具有分别大约为12.67mm和大约为11.15mm的优选内径的圆柱形凹槽17的杯盖过盈配合。前述测量都有加减0.127mm的优选公差。另外,最优选的进一步的尺寸是阀门表面30的厚度。其最优选为约0.58mm厚,优选的公差仅约加减0.05mm。已经发现,这些尺寸对于提供阀门表面30正确的弯曲和缝隙32当时用时在抽吸作用下打开是非常重要的。
优选地,流量控制阀门20由单件弹性材料制成,以方便其容易插入和从凹槽17移走。当然,流量控制阀门20可以由两个分开的阀门元件制成,后者适于插入到凹槽17中或者与啮合盖14啮合。所使用的弹性材料最优选为硅树脂,但TPE(热塑性弹性体),天然橡胶,以及合成橡胶(例如异戊二烯)也是优选的。
下述数据证明了根据本发明的流量控制阀门20改进的流速。测试了图3(阀门A)的流量控制阀门20的六个例子,与之比较的是图1(阀门B)所示的流量控制阀门的六个例子,和授予Belanger的美国专利No.5,079,013(阀门C)公开的一个流量控制阀门的十个例子。

对于本领域的普通技术人员来说,可以对前述公开的技术作各种改进。因此,前面的说明和附图仅仅是为了表示本发明的某些优选的实施例,并且在所附权利要求的精神和范围内可以对这些实施例作各种显而易见的改进。
