Description

饮料容器
本发明涉及饮料容器,其包括适合于作训练杯或类似杯子使用的饮料容器。
通常,训练杯(即,一种具有盖的杯子,有一嘴部与盖相连,嘴部通常为一管口形式)被儿童使用,作为从使用婴儿哺乳瓶到使用普通杯子或玻璃杯之间的过渡。训练杯经常是儿童学习自己饮水的第一步。设置带有一管口的盖子是为了使儿童更容易自己饮用,这是因为儿童可把管口置于嘴中,这与以前把哺乳瓶的奶嘴置于嘴中的方式完全相同。然而,这种年龄的儿童本性活泼。吃饭则变成一种吵闹和烦杂的经历。训练杯经常会被剧烈地摇晃或碰撞。在这些情况下,对于传统的训练杯而言,这将导致溢出。为了便于携带,则需要在盖的下面将一独立的封闭盘安装于杯子,或者要求盖子有一可调节的封闭装置。
本申请人的英国专利申请No.2266045描述了许多适合于供老、弱者作训练杯或杯子使用的饮料容器。这些饮料容器包括一敞口的、通常是杯形的容器和一用于盖住容器敞口的盖子。盖子具有一相连的嘴部。如果没有一定的吸力施加于嘴部的话,阀的设置可用来防止液体从容器的内部通过嘴部流出,从而,使用者可仅通过对嘴部施加吸力吸取液体。这种布置在克服溢出的问题上被证明是成功的,但其结构相对复杂且昂贵。这种布置在克服溢出的问题上被证明是成功的,但其结构相对复杂且昂贵。
GB 2,279,130公布了一种阀,用于分配液体。当使用者将嘴部放入嘴里并咬住阀端区域时,这种阀被打开。当嘴部被释放后,阀封闭件回到其原始结构,使阀闭合。
FR 1,364,891公布了一种阀,适于输送浆状、半液体或液气物质。尽管在阀上的穿孔被称为“自密封”,但仍然需要对容器施加压力,以使容器中的内容物从阀中流出。由于内容物处于压力下,因此形成阀的板相对较厚。
根据本发明,提出了一种可被使用者从中取出饮用液体的制品,该制品具有一个设置有由弹性易弯曲材料构成的柔性膜的阀,该膜设置有至少一个这样的狭缝,从而液体通过在阀区域中仅施加一个能使柔性膜被向外吸起从而打开膜上狭逢的吸力即从制品被抽出,其特征在于,膜具有在正常状态下与液体从制品被抽出的方向相反的向制品内凹盘形,并且当吸力被卸掉时由膜的自身弹性回复正常内凹状态盘形的闭合。
在阀的正常状态下,由狭缝或穿孔形成的孔是闭合的,即形成膜的材料在自身的弹性作用下关闭。同样,如果有适中的内部压力向外作用于阀,例如当容器被倒转时容器中内容物的重量作用在阀上,这种压力有助于在狭缝或穿孔的两侧对膜的材料加压,使其闭合在一起。
然而,如果例如通过嘴施加吸力,本发明的阀也会打开以使液体通过阀而自由流动。例如,阀可被置于一用于容器的盖上或者容器的一凸出的嘴部内:如果嘴部被放入使用者的嘴中且使用者施加吸力,这将使柔性膜反向弯曲,使狭缝或穿孔打开,从而使液体自由流动。液体还可被结合在一饮料软包装的顶部:可采用上述方式施加吸力以便直接从软包装中饮用,也可通过挤压软包装以增加自身内部压力通过阀排出液体以便将液体倒入一独立容器中。然而,这些方式也可通过将饮料吸管推入阀内的孔中来代替,然后,使用者通过吸管来饮用。
当施加吸力时,中凹形膜被导致反向弯曲,使液体通过孔被吸出,而当吸力被卸掉时,空气通过孔进入容器中,使阀两侧的压力平衡或接近平衡,在自身弹性的作用下使阀回到正常的状态(即,向内的中凹形)。
狭缝阀在过去曾被提出,但通常,该狭缝阀被制成在流动方向上的中凹形或拱形。就本申请人所知,以前从没有提出过这样一种狭缝阀,其被制成在与阀所控制的液体流动方向相反的方向上呈中凹形,或更具体地说,是一种在与液体流动相反的方向上被制成中凹形的狭缝阀,其被设计用来控制液体,且该阀使空气的流动与液体的流动方向相反。
在优选实施例中,阀膜与容器或用于容器的盖共同模制。在盖具有一嘴部的情况下,最好与一在盖的下端周向延伸的护罩形成一单一体,使盖可装配在杯形容器的开口内,一在径向周向延伸的脊用于限制护罩进入开口。
在另一实施例中,阀可被结合在饮料吸管的端部。在这种情况下,吸管可被插入传统的软包装中,刺穿其通常的箔膜,然后形成相对有效的密封,吸管中的阀以上述的方式组合使用。
现将参照附图仅通过举例的方法对本发明的实施例进行描述。
其中:
图1为饮用容器的剖视图;以及
图2为饮料纸盒的示意图。
参照附图可见,在传统形式顶部开口的杯形容器10上,有一盖1。盖1为整体结构,并与总体标号为2的一阀共同模制。盖1在其下侧具有一个一体的周向护罩3,在该护罩的上部边缘绕有一周向脊4,该脊沿径向向外延伸。当盖1被装在杯形容器10的顶部开口中时,护罩3伸在杯的内部,而脊4被放置在容器上部的周向边缘上。这样,就提供了一种足够的密封来防止饮料的溢出。除了被护罩3所围绕的开口外,盖1上还有一个在向上伸出的嘴部6内的开口5。嘴部6的大体形状与传统的训练杯相似。而区别是本实施例中设置了阀2。阀2由一具有弹性的柔性板或盘7形成,该板或盘7为橡胶或最好用塑料材料,阀2具有一个或多个细长切口8。单一切口即可满足要求,然而最好设置一对切口相互交接,以形成一交叉切口。这一单一切口或一对切口中的每一切口都是那种细小的狭缝而不是一种上下贯通的切口,因此在阀的自然状态下,即在形成阀的板7被轻微向嘴部内弯成中凹形的情况下,这种切口也是完全地封闭的,由此防止容器内的液体流出并防止容器外部的空气流入。通过用带尖的工具来刺穿盘7,可在盘7上设置一孔,以取代细长切口8。在这两种情况下,细长切口或其它的孔是通过在盘7上进行切割形成的,无需取下任何材料。
盖1的材料与柔性阀板7不同,是由相对硬的塑料材料例如聚碳酸酯或聚丙烯制成。柔性阀板7的材料可选择成其可容易地与嘴部共同模制。如果柔性阀板由与盖1的其余部分相似的塑料材料形成,则有利于这种共同模制。可通过使板7非常薄,使其具有比盖更高的柔韧性,或通过用相似的塑料但加入大量的可塑剂来制造它。在塑料材料热硬化的过程中,盖1其余部分的材料在用于柔性板的材料被加入到模型中之前被部分地弯曲,然后这种弯曲进一步持续一个时期以使盖硬化,但仅使板7的材料部分地硬化,作为替换,板7可以一独立元件的形式形成,其为一种没有被热硬化的塑料材料,并可被插入到用于形成盖1其余部分的材料的模型中,盖的其余部分由热硬化材料形成,从而通过弯曲可使盖的其余部分硬化,并使阀一体成形在嘴部内。在一种优选的布置中,盖的其余部分由聚丙烯形成,并在模型中预成形。然后,用于板7的材料作为一种液体被加入到模型所要求的区域中,再进行弯曲。用于板7的优选材料是一种以EVOPRENE商标出售的块共聚物,其成分为一种苯乙烯-乙烯-丁烯-苯乙烯共聚物。
对塑料模制领域的技术人员来说,其它的布置也将很容易地发生。
在已经示出和描述的布置下,在阀处于自然的没有被偏置的情况下,饮料不会从孔8中泄漏出来;如果在嘴部施加一定的吸力,柔性板7将被向上吸起,从而打开孔8,使液体被抽出。当这种吸力被释放掉后,空气向下穿过孔8,直到阀回到原始位置,在此位置上阀将再一次闭合。在正常的内部压力影响下,例如如果容器被倒转,这种压力将趋于在孔8的两侧共同加压于板7的材料,从而关闭该孔。
尽管阀的应用已经在上文结合一具体制品(即这种供老、弱者使用的训练杯或杯子的盖)的视图进行了描述,这种阀还具有更广泛的用途。具体地说,这种阀可结合在饮料软包装20的顶部,如图2所示。在这种情况下,使用者可通过使软包装的阀部对准嘴并施加吸力,或通过将吸管插入阀22的孔中,从而从软包装20中喝到饮料。在上述任一种情况下,通过挤压软包装以增加其内部压力,可使液体从软包装中排出。在另一实施例中(未示出),阀可结合在一饮料吸管的端部,当吸管插入传统的软包装饮料中时,刺穿其通常的箔膜,但形成一相对有效的密封;吸管中的阀以上文中参照附图所描述的相同方式组合使用。
