Description

特别是用于一次性杯子的盖
技术领域
本发明涉及杯盖,特别是用于一次性杯子的盖,在杯子中沏泡的液体饮料被分配。具体地,本发明涉及这样的盖:其允许安全、方便地制备沏泡饮料,而无需在喝饮料之前去掉和处理沏泡袋。
背景技术
许多液体饮料通过沏泡制成。这些饮料包括茶饮料和咖啡饮料,其中茶饮料可通过沏泡源自野茶树植物的绿茶、红茶、白茶或乌龙茶或沏泡其他植物原料以泡出所谓的药茶而制成,咖啡饮料则通过沏泡炭烧咖啡和磨碎的咖啡豆或通过沏泡加工的咖啡产品-如即溶咖啡粉或即溶咖啡粒而制成。优选的液体饮料是茶饮料。
诸如那些在出门在外的环境里(例如快餐或外卖销售点或公共饮食服务场合,如工作地的食堂)售卖给消费者的液体饮料经常装在容器里供应,容器上有盖以便将溢出减到最低。这种盖可设置有饮孔,消费者通过它喝饮料。这种饮料通常通过如下方式制成:在容器内的水里浸入沏泡袋(如茶袋),并允许沏泡袋里所装之物泡足够时间以达到消费者所需的饮料浓度。
为了促进沏泡,许多消费者会在水里搅动沏泡袋。如果沏泡袋上设置有绳和标签,则用户会利用绳在容器内的水中上下移动沏泡袋。经过足够的沏泡时间,用户必须取出沏泡袋而不让其和水接触,以阻止进一步沏泡。这个操作可能会很麻烦,因为当沏泡袋离开水时它还含有水,所含的水会在沏泡袋移动时滴落。如果容器上设置有盖且该盖必须在搅动和取出袋之前被去掉,那么上述对沏泡袋的搅动和取出就会变得更困难。去掉盖,在饮料被饮用之前可选地更换盖,会增加饮料泼洒出来的风险。当饮料还热的时候,这会增加消费者被热的液体烫伤以及液体泼洒到消费者衣服上或周围环境中的机率。
WO2004/026722(联合利华)公开了有盖的容器,其中盖上设置有开口,开口具有能够夹住沏泡袋的绳的第一部分以及第二部分,其中沏泡袋的绳能够通过第二部分移到容器的里面和外面。这种布置可以使消费者通过穿过开口的第二部分牵拉绳子即可在容器内移动沏泡袋,然后将沏泡袋锁定在提升的位置,从而通过在开口的第一部分夹紧绳子来停止沏泡过程。
尽管WO2004/026722中公开的盖和容器确保以安全和方便的方式向消费者提供沏泡液体饮料,并且无需在饮用饮料之前取出和处理沏泡袋,但同时它们也有一定的缺点。从制造角度来看,将绳和标签穿过盖上的开口是难以自动化完成的。从用户的角度来看,将沏泡袋锁定在提升的位置不能总是保证沏泡过程完全停止或者确保沏泡袋不影响饮用过程。举例来说,根据沏泡袋被提升的高度和/或饮料在饮用过程中在容器内的移动情况,沏泡袋可能会再次接触饮料和/或堵塞饮孔。而且,拖在杯子外面的一节绳子可能会松弛摇摆和/或在饮用过程中触碰到用户的脸。
DE202005012125U1(Horst Mahler)公开了一种一次性饮水杯,其包括附接在盖上的用于容纳茶叶的穿孔容器。但是,DE202005012125U1中公开的盖是不方便的,因为要停止沏泡过程,则必须将盖从容器上拿开。
因此,我们开发出了一种装置,其使得可以安全、便利的方式向消费者提供沏泡的液体饮料,同时还无需在饮用饮料前拿开和处理沏泡袋,而且没有上述提到的一个或全部缺点。
发明内容
在第一个方面,本发明提供一种特别是用于一次性杯子的盖,所述盖包括:
(a)沏泡腔,其具有至少一个透水壁并包含可沏泡物质;
(b)用于将盖附接至杯子的边缘的凸缘;和
(c)主体部分,其包括可移动部分;
其中,沏泡腔附接至可移动部分,并且其中在盖装配到杯子的情况下,可移动部分能够在大致垂直于所述边缘的平面的方向(A)上在抬高位置和降低位置之间可逆地移动。
在另一些方面,本发明涉及一种容器,其包括附接至杯子的盖,本发明还涉及利用该容器制作饮料的方法。
利用附接至可移动部分的沏泡腔,免去了使用带有绳子的单独的沏泡袋的需要。而且,可移动部分可在抬高位置和降低位置之间可逆移动的设置使得沏泡腔能够被降低以接触杯中液体来沏泡可沏泡物质,然后被抬高以便使透水壁脱离与杯中液体的接触,从而停止沏泡过程。由于沏泡腔可以被降至杯中的深度不受盖和/或杯子的直径的约束,因此该平移操作是特别方便的。
特别优选的是,可移动部分包括可溃缩结构,因而可使盖对容器总高度的影响最小化,当考虑到容器抵抗倾倒的稳定性时,这一点可能会很重要。优选的是,可溃缩结构可包括一个或多个褶。更优选的是,当可移动部分移动离开边缘并进入杯子时,所述一个或多个褶打开。可选地或另外地,可移动部分可包括可伸缩结构。
沏泡腔可与可移动部分一体模制而成,或者可以是可附接至那里的独立部件。特别优选的是,沏泡腔不与可移动部分一体模制,因为例如这使得可独立于盖的剩余部分而单独制作一系列的多个沏泡腔,每个系列中有不同的可沏泡材料。于是消费者可以根据他的品味选择包含可沏泡物质的沏泡腔并接着在沏泡前直接装配好盖。沏泡腔不与可移动部分一体模制的另一个优点是,盖的剩余部分可能更容易存放,因为例如它可以叠起来堆放。优选的是,沏泡腔包括突起,并且所述突起可通过可移动部分上的孔接合,因为这使得可以容易地组装盖。但是,为了使盖对容器总高度的影响最小化,优选的是,突起不要长于沏泡腔的剩余部分,或者换句话说,突起的高度不大于沏泡腔整体高度的50%。突起可方便地形成球形柄或手柄,用户可以通过它来移动可移动部分。另外的或可选的是,突起上面可以设置标记以标示可沏泡材料的类型,可沏泡材料的风味和/或可沏泡材料的品牌。确保沏泡腔不会轻易从可移动部分上拆卸下来的方面的布局是,其中突起包括倒钩。
为了使消费者无需在沏泡之后操作湿的沏泡腔,优选的是,盖还包括饮孔。消费者因而可以无需去掉盖就能沏泡和饮用饮料。为了使沏泡腔对饮用过程的妨碍最小化,优选的是,沏泡腔定位成在第一径向上离开盖的中央,并且饮孔定位成在与第一径向大致相反的径向上离开盖的中央。 
附图说明
现在将参照附图进一步说明本发明,附图中:
图1是根据本发明的盖的截面立体图。
图2是包括图1所示盖的容器的立体图。
图3是图2所示容器的立体图,其部分用截面显示,且可移动部分处在抬高的位置。
图4是图2所示容器的立体图,其部分用截面显示,且可移动部分处在降低的位置。
具体实施方式
现在将参考图1至4所示的下列优选实施例对本发明作进一步说明。
盖(100)包括凸缘(120),凸缘(120)环绕主体部分(130)并与主体部分(130)一体模制而成。凸缘(120)可附接至一次性杯子(200)的边缘(210)上,优选地与该边缘一起形成不透液的密封。主体部分(130)包括可移动部分(135),该部分具有一系列同心褶(135a)并包围孔(135b)。主体部分还包括抬高的嘴,该嘴具有饮孔(140)。所述可移动部分(135)的孔(135b)定位成在第一径向上远离盖(100)的中心,并且饮孔(140)定位成在与第一径向相反的径向上远离盖(100)的中心。
沏泡腔(110)具有大体上为半球状的壁(111),该半球壁透水并包围沏泡材料(未示出),如茶叶。所述壁(111)可包括刚硬材料,其如图所示那样具有穿孔。此外或可选的是,所述壁(111)可包括过滤材料,如通常用于茶叶袋制作里的过滤材料,比如无纺布或尼龙网布。从壁(111)的中心垂直向上延伸的是空的突起(110a),其具有倒钩(110b)。突起(110a)通过孔(135b)接合在可移动部分(135)上并由于倒钩(110b)的存在而被保持在那里。因此,使沏泡腔(110)被固定在可移动部分(135)的下边。
在使用中,消费者选择容纳所需沏泡材料-例如绿茶的沏泡腔(110)。沏泡材料可通过印刷在突起(110a)上的文字“立顿?绿茶”来识别。消费者然后将突起(110a)放置在盖(100)的可移动部分(135)上的孔(135b)内,并穿过其中推动突起(110a)直到倒钩(110b)卡接在可移动部分(135)的顶部。
液体(未示出)-例如沸水之后被倒入杯子(200)中,直到杯子(200)例如有80%满(相对满装容量)。盖(100)之后通过凸缘(120)附接至杯缘(210)上。容器现在的配置如图2和3所示。
消费者现在通过抓住突起(110a)并向下推动来启动沏泡过程。其结果是褶(135a)打开,且可移动部分(135)和附接在那里的沏泡腔(110)沿方向(A)向下移动以使透水壁(111)接触杯中液体。褶(135a)的形状设置成使得在达到预定的向下运动程度后,可移动部分(135)停在图4所示的降低的位置。因而消费者能够停止推动突起(110a),且不需要在泡茶的同时拿着容器。
当达到所需的沏泡浓度后,消费者再次抓紧突起(110a),这次向上拉。结果褶(135a)再次摺起,且可移动部分(135)和附接在上面的沏泡腔(110)沿方向(A)向上移动以使透水壁(111)脱离与杯(200)中液体的接触,从而停止沏泡过程。褶(135a)的形状设置成使得在达到预定的向上运动程度后,可移动部分(135)停在图3所示的抬高的位置。
消费者现在可以从饮孔(140)喝沏泡饮料(例如绿茶),而不必操纵沏泡袋,也不会被摆动的沏泡袋和/或绳妨碍,并且知道饮料的浓度在喝的过程中不会改变,因为沏泡过程已经被有效地停止。
