Abstract
一种特别适合饮料用的容器，它包括：一个端壁(5)，在该端壁上形成一条闭合的弱化线(6)以限定封盖(7)和相应孔(8)的轮廓线；以及一个与封盖(7)相连的拉杆(10)，该拉杆可手动操作以沿弱化线(6)撕开端壁(5)并且将封盖(7)从容器壁上除去，其特征在于，它包括一个柔性舌片(9)，该舌片通常压靠在端壁(5)的外表面上，并且它的一端(9a)固定到与封盖间隔开的容器端壁(5)的外表面上，而且由于手动将封盖从容器壁上除去，舌片(9)可以采取弯曲构形，其中相连的封盖位于与孔(8)脱离接合的位置，设置了约束装置(15；19，20)用以将舌片保持在弯曲构形下。
Description
本发明涉及一种容器，特别涉及一种饮料用容器，通常术语把它称之为“罐”。
更具体而言，本发明涉及这种类型的容器，该容器包括：一个端壁，在该端壁上形成一条闭合的弱化线以限定封盖和相应孔的轮廓线；以及一个与封盖相连的拉杆，该拉杆可手动操作以便沿弱化线撕开端壁并且将封盖从容器壁上除去。
这种类型的已知容器的缺点在于：当容器被打开时，拉杆和与之相连的封盖与容器机械分离，因此它们可能会散落到环境中。
为了防止这一问题发生，已建议在本说明书开头部分定义的那种饮料容器，其中限定封盖轮廓线的弱化线被打开，同时操纵拉杆撕开容器的顶盖并使封盖经相应的孔朝向容器内部倾斜。封盖被撕开和倾斜后，它仍牢固地连接在容器上而不会单独散落于环境中。然而，这种技术方案的缺点在于：由于容器的开口，封盖会“浸入”饮料中而随之带来污染的危险，而这种污染使得在饮料的生产和包装过程中所采用以及确保饮料无菌的预防措施无效。
美国专利US-A4，231，487公开一种具有权利要求1前序部分中所包含特征的容器。这一文献公开了一种用于将易开口容器的板状部分除去的拉片，由此影响到弯曲结构中被去除部分的折叠。这个拉片是由塑性材料模塑制成以具有多个横向延伸折叠线的记忆。该记忆折叠线逐渐有效地将该拉片卷成具有三角形截面的小型塞条型。
这一技术方案在应用于工业生产上时复杂且困难，因为拉杆和可除去的板部分必须具有和记忆折叠线对准的横向折叠线，以便被折叠在一起并折叠到拉片内。
美国专利US-A4，203，528揭示了另一个技术方案，其中拉条具有记忆的铰接部分，该记忆装置布置在容器的开口结构中，可去除的板状部分自动摇摆到径向上超出容器侧壁的位置。
后一种技术方案的缺点是在开口结构下可去除的板状部分处于一个非常暴露的位置，并且它的锋利边缘能伤害消费者。
本发明的目的是提供一种容器，它克服了已知技术方案的缺点并具有更简单且价格更低廉的结构。
按照本发明，这个目的由根据权利要求1的容器所实现。
参照附图仅借助于非限定性的实施例，从下面的详细描述中将更加清楚本发明容器的其它特征及优点。
图1-4是本发明容器的透视图，分别表示封闭结构(图1)，两个连续的开口阶段(图2和图3)，以及在使用中最后的开口形状(图4)。
图5-8是容器另一实施方案的透视图，它同样表示封闭结构(图5)，两个连续的开口阶段(图6和图7)，以及使用中最后的开口形状(图8)。
图9是沿图4中线Ⅸ-Ⅸ截取的剖面图，以及
图10是沿图8中线Ⅹ-Ⅹ截取的剖面图。
参照附图，本发明的饮料容器1包括一个大体上呈圆柱形的贮罐2，该贮罐由诸如铝、钢或其合金制成。贮罐的侧壁3和底部4最好通过拉拔技术制成单一件。
顶盖5也可由诸如铝或其合金制成，采用接缝将顶盖5密封式地固定到贮罐的顶端。容器壁和顶盖的内表面可以已知方式涂覆一层对于所盛装制品而言为惰性的聚合物材料或清漆的薄膜。
在顶盖5的外表面上例如通过局部切割(半冲压)形成一条弱化线6；弱化线6本身是闭合的，以便在顶盖上邻近于该顶盖的周边限定封盖7和相应的孔8。
当容器处于封闭构形中时，标记为9的柔性舌片沿纵向在顶盖上延伸，该舌片的端部9a被固定在顶盖的形成封盖7的那部分以及操纵拉杆10上，而其另一端部9b邻近于与封盖间隔开的顶盖周边固定到顶盖上。舌片例如通过凸台11固定到封盖和拉杆上，该凸台11与封盖形成整体并且穿过舌片9中的孔和操作拉杆10中的相应孔，同时该凸台11象一个铆钉一样在这些孔的另一侧被镦粗(见图9和图10)。同样，舌片的另一端部9b通过一个或多个镦粗的凸台12连接于顶盖，该凸台12与顶盖整体形成且穿过舌片上的各相应孔。
当容器处于封闭构形中时，拉杆10最好覆盖并保护弱化线6以防止由于平行于容器轴线的载荷而致使顶盖5沿该弱化线撕开或破裂开。意图借助于适合此目的的任何其它装置将舌片固定到顶盖和封盖上。
舌片9由柔性塑料或金属材料制成，优选由诸如铝或其合金等金属板制成。舌片优选地具有一条或多条预成形弯曲线，例如一对间隔开且横向于舌片长度方向设置的弯曲线13、14。预成形弯曲线使得舌片在去除盖子时能自行弯曲。
在图1至图4和图9所示的实施方案中，将舌片9保持在弯曲构形(图4和图9)下的约束装置包括一个蘑菇形凸台15，该凸台邻近于孔8并位于面向舌片的端部。具有一个平坦头部16和一个柄部17的凸台15可以通过诸如冲压和镦粗的方法与顶盖整体成形。当舌片处于弯曲构形时，封盖的前端与顶盖相分离，它可以在凸台头部16和顶盖上表面之间形成的空间内与该头部16的下面接合，而且该封盖的前端抵抗舌片的弹性回复力使之限制在这个位置中，该弹性回复力趋向于将其保持伸展构形。在这个实施方案中，舌片优选具有这种方式定位的通孔18，即：当容器处于其舌片延伸过顶盖的封闭构形时，凸台的头部16穿过所述孔，因而将舌片保持在基本上平坦的位置上。
在这个实施方案中，为了打开容器和饮用其内盛装的饮料，从图1所示的封闭结构开始，消费者操纵拉杆10将封盖7从顶盖上分离，此后他将舌片沿弯曲线13和14自行弯曲并且在凸台15的头部16的下面与封盖的前缘接合。因此，封盖在它与孔8脱离接合的位置上保持与容器的连接。
在图5至图8和图10所示的实施方案中，约束装置包括一个例如与舌片形成整体的销19，该销由冲压成形且布置在邻近于舌片端部9b的位置，该约束装置还包括一个在舌片中形成的通孔20，将该通孔设置成当舌片自行弯曲时，该通孔处于面向销19的位置，从而可以使销19插入该孔中以将舌片限制在弯曲构形。在这个实施方案中，趋向于使舌片回复延展构形的弹性回复力使销19与孔20配合，这种配合将舌片保持在弯曲构形中。
本发明并未意图限制于上述的具体约束装置，而是包括在按照本发明形成的容器范围内，此外还具有其它的约束装置，它们能使舌片以及与之相连的封盖限制在它们不与孔8相接合的构形中，当打开容器后，其内盛装的饮料不会与封盖的上表面接触，且消费者的嘴唇不会与封盖锋利的边缘接触。
因此，例如，可以在舌片弯曲时而相互叠置的区域中设置互补形状的连接装置，例如，可以在舌片上表面的部分9c(图3)中设置一个成形凸台(未示出)或一个冲孔，以便将它配合在舌片相邻部分的上表面(图3)中形成的一互补凹槽内；同样，该部分9d下表面上的凹槽可以与封盖7下表面凸出的互补凸台相配合。
此外，上面参照一具体容器而描述的打开装置也可以用在任何其它容器上，其中所述具体容器在此上述情况下为饮料罐。
