Description

用于打开饮料罐的构造布置
技术领域
根据本发明的性质，本发明涉及一种应用于饮料罐的新颖构造布置，通过在罐的端壁(通常是上壁或盖子)中设置通气开口和可选的倾倒开口，当使用者/消费者手动致动第一致动拉片和如果需要的话致动第二致动拉片时，允许所述两个致动拉片，与分别形成通气开口和倾倒开口的通风面板和倾倒面板一起，在所述开口中每一个释放后立即容易且快速地从罐的上端壁上拆下，从而允许快速和容易地打开饮料罐。
背景技术
在现有技术中众所周知，使用具有端壁的罐，该端壁设有第一可撕开面板和第二可撕开面板，以便分别形成通气开口和倾倒开口，通气开口与倾倒开口在直径上间隔开，从而当罐倾斜到水平位置时，通气开口相对于倾倒开口采取上部位置，以便在饮料通过倾倒开口从罐中倒出时，允许空气通过通气开口连续进入罐中。通气开口的设置允许饮料以均匀的流动和更快的速度从罐中释放。
专利文献BR 20 2016 000915-0、BR 20 2016 006035-0和US 2014/0263320 A1说明了上述构造的类型，根据该构造，使用者/消费者在单个致动拉片上的致动最初促进第一面板(通气面板)的破裂，形成通气开口以便于饮料通过倾倒开口排出，该倾倒开口随后通过使用者/消费者在单个致动拉片上渐进的动作在第二面板破裂时形成。
在所述已知的具有两个可断裂面板的饮料罐中，单个致动拉片的致动不仅通过移除通气面板而导致通气开口的强制形成，而且随后通过将第二可断裂面板或倾倒面板压到罐的内部而导致倾倒开口的强制形成。倾倒面板围绕其可断裂轮廓的减小且未减弱的延伸部弯曲，该延伸部作为由罐的相应端壁的金属箔本身限定的铰链。在这种已知的构造中，倾倒面板保持附连到罐的端壁上，突出到罐的内部，保持与饮料接触，并且当罐在打开之前并且主要在用作“饮用杯”之前，没有经受很高效清洁时，将通常存在于所述罐的端壁或盖子外部的所有病原微生物传送给饮料，供使用者/消费者摄取。除了保持倾倒面板附连到罐上并突出到罐的内部之外，这种具有单个拉片的解决方案防止使用者/消费者仅仅促进通气面板的破裂以仅形成用于引入吸管以吸取饮料的通气开口。
另一方面，专利PI 0403324-8的解决方案提供了两个致动拉片，这要求使用者/消费者拉动一个致动拉片，以便形成通气开口并允许接近另一个致动拉片，从而可选地拉动该致动拉片以形成倾倒开口。尽管只允许形成用于引入吸管以吸取饮料的通气开口，但是所述现有解决方案并没有消除在形成倾倒开口时保持倾倒面板突出到罐内部的不便。
专利文献GB 353,598、US 3,655,091、US 4,042,144、US 4,913.305和BR 20 2014032067-4描述了用于通过单个杆或拉片在罐的端壁中提供倾倒面板开口的不同构造，当被使用者/消费者致动时，杆或拉片最初促进位于倾倒面板的可断裂轮廓的弱化线中的破裂，允许拉片或杆由使用者/消费者拉动，完成倾倒面板整个轮廓的破裂，然后将倾倒面板从罐上拆下，而没有被压到罐的内部和接触储存的饮料的不便。
在消除将倾倒面板弯曲到罐内部的问题的同时，上一段中提到的构造解决方案不允许使用者/消费者提供通气开口以允许饮料以均匀的流动和更快的速度从罐中释放。
专利文献US 3,477,608公开了一种构造解决方案，通过单个杆或拉片在罐的端壁上形成通气开口，随后形成倾倒开口，当被使用者/消费者致动时，该杆或拉片最初促进通气面板的完全破裂和倾倒面板可断裂轮廓的弱化线的局部破裂，允许使用者/消费者拉动单个杆，从而完成倾倒面板的整个轮廓的破裂，然后将倾倒面板从罐上拆下，而没有被压到罐的内部和接触储存的饮料的不便。
尽管消除了将倾倒面板弯曲到罐的内部以及提供倾倒开口和通气开口的问题，但是文献US3,447,608中描述的构造不允许使用者/消费者仅促进一个通气开口(如果需要的话)以通过普通吸管吸取饮料，而没有在形成具有较大尺寸的倾倒开口时产生裂开的风险。在这些解决方案中，单个拉片或杆促进两个开口的强制形成。
发明内容
由于上述和与已知解决方案相关的缺点，本发明的一个目的是提供一种用于打开饮料罐的构造布置，其允许使用者/消费者提供通气开口的形成，并且随后，如果需要，提供与通气开口间隔开的倾倒开口的形成，通气开口和倾倒开口都由罐的端壁的相应面板形成，这些面板形成通气开口和倾倒开口，并且从罐完全向外拆下。
本发明的构造布置应用于一种饮料罐，该饮料罐包括端壁，在端壁中限定了通气面板，并且与通气面板间隔开的是具有较大轮廓的倾倒面板。
根据本发明，两个面板的轮廓完全由破裂线限定，还设置有第一致动拉片和第二致动拉片，第一致动拉片具有提取端部和抓握端部，提取端部在外部固定到通气面板，抓握端部手动地和有角度地远离罐的端壁移位并与通气面板一起从罐分离，第二致动拉片可选地在通气面板被移除后被致动，并且具有冲压端部和抓握端部，冲压端部在外部固定到倾倒面板并且设置有下端齿以压靠在限定倾倒面板的轮廓的破裂线的面对点状区域上，抓握端部远离罐的端壁的手动角移位最初使破裂线的所述点状区域断裂，并且随后将倾倒面板与所述端壁分离。
附图说明
下面将参照附图描述本发明，附图是作为本构造布置的可能实施例的示例给出的，其中:
图1表示处于关闭状态的此处考虑类型的饮料罐的上平面图，该饮料罐设置有本发明提出的第一致动拉片和第二致动拉片；

图5表示图4所示的径向截面图，但是第二致动拉片的抓握部已经显著地远离罐的端壁移位，引起破裂线的其余部分破裂，以及随后倾倒面板相对于罐分离，以便形成倾倒开口；和
图6表示图5所示的径向截面图，但是两个致动拉片和两个面板完全从罐上拆下并丢弃，用于形成通气开口和倾倒开口。
具体实施方式
如附图所示和以上所讨论的，本发明的构造布置被应用于包括端壁10的类型的饮料罐L，端壁10通常是上盖的形式，被限定在罐L的通常为圆柱形的侧壁20的端部之一中的相邻边缘21包围。端壁10结合有通气面板11和倾倒面板12，通气面板11和倾倒面板12通常以直径相对的布置间隔开。应当注意，倾倒面板12的轮廓通常比通气面板11的轮廓大得多。
根据本发明的第一方面，通气面板11和倾倒面板12的轮廓完全由相应的破裂线11a、12a限定，这允许所述相应的面板沿着其轮廓破裂，用于分别形成通气开口A1(如图4、5和6所示)以及随后可选地形成倾倒开口A2(如图5和6中最佳地示出)。这种类型的罐可以用本领域公知的不同方式构造，这些方式不是本发明的一部分。
罐L还包括第一致动拉片30，该第一致动拉片30由适合于当前用途的任何金属合金一体地构造而成，该第一致动拉片30具有提取端部31，该提取端部31通过任何已知构造的保持元件35在外部固定到通气面板11，并且该保持元件35例如可以采取铆钉35a的形式，该铆钉35a密封地结合到端壁10的通气面板11。如图4所示，第一致动拉片30还包括抓握端部32，该抓握端部32大致为环形形状，并且手动地和有角度地远离罐L的端壁10移位，使通气面板11的破裂线11a断裂，并且将通气面板11与罐L的端壁10分离。
第一致动拉片30的提取端部31可以一体地且通过铰链区域33a结合有拉片部33，该拉片部33通过倒圆“C”形切口34从第一致动拉片30上切下，切口34向铰链区域33a开口，并允许所述拉片部33限定第一致动拉片30的在通气面板11外部固定到保持元件35的部分。
第一致动拉片30的提取端部31还可以在拉片部33的切口34和铰链区域33a外部的区域中结合有位于通气面板11的破裂线11a上方的端部下齿36，以便压靠所述破裂线11a的面对点状区域11b，在所述点状区域11b使破裂线断裂，并允许第一致动拉片30的抓握部32围绕铰链区域33a进行上升角移位，直到出现通气面板11的初始破裂，并且随着第一致动拉片30的渐进上升角移位，获得破裂线11a的完全破裂以及通气面板11和第一致动拉片30相对于罐L的随后的完全分离。
当设置端部下齿36时，最初围绕拉片部33的铰链区域33a的第一致动拉片30的手动角移位导致破裂线11a的初始和最终局部破裂。致动拉片30的渐进手动、有角度和上升移位导致通气面板11的破裂线11a完全破裂，然后通气面板11与保持元件35一起整体地从罐L分离，形成通气开口A1(见图4、5和6)，当使用者希望以这种方式吸取饮料时，通气开口A1的尺寸优选地被设计成能够容纳吸管，降低溢出的风险。
本发明的构造布置还包括第二致动拉片40，该第二致动拉片40具有通过保持元件45在外部固定在倾倒面板12上的冲压端部41，该保持元件45具有任何已知的构造，并且例如可以采取铆钉45a的形式，该铆钉45a密封地结合到端壁10的倾倒面板12，以及环形抓握端部42，抓握端部42可以在移除第一致动拉片30之后手动地和有角度地远离罐L的壁10移位，以便使倾倒面板12的破裂线12a断裂，并使倾倒面板12与罐L的端壁10完全分离，形成倾倒开口A2(见图5和6)。这种构造允许通气面板11的破裂线11a的轴向投影被包含在第二致动拉片40的抓握部42的环形内部。
第二致动拉片40的冲压端部41一体地并通过铰链区域43a结合有拉片部43，该拉片部43通过倒圆“C”形式的切口44从第二致动拉片40上切下，切口44向铰链区域43a开口，并允许所述拉片部43限定第二致动拉片40的在倾倒面板12外部固定到保持元件45的部分。
第二致动拉片40的冲压端部41还结合有位于倾倒面板12的破裂线12a上方的端部下齿46，以便压靠位于切口44和拉片部44的铰链区域43a外部的破裂线12a的面对点状区域12b，在所述点状区域12b使破裂线12断裂，并允许第二致动拉片40的抓握部42围绕铰链区域43a进行上升角移位，直到发生倾倒面板12的初始破裂，并且随着第二致动拉片40的渐进上升角移位，获得破裂线12a的完全破裂以及倾倒面板12、保持元件45和第二致动拉片40相对于罐L的随后的完全分离。
在图示的构造中，第一致动拉片30的提取端部31穿过第二致动拉片40的环形抓握端部42定位，第一致动拉片30的抓握端部32定位在第二致动拉片40的冲压端部41上方，并且第一致动拉片30的提取端部31定位在第二致动拉片40的抓握端部42下方。
利用上述构造，如果使用者/消费者希望不使用吸管直接从罐中吸取饮料，他/她有必需首先将通气面板11与第一致动拉片30一起拆下。随后，使用者/消费者可以提供第二致动拉片40的抓握部42的手动和角移位，以便将其与倾倒面板12一起从罐L的端壁10上拆下。
如图1和2所示，在通气面板11和倾倒面板12仍然关闭的情况下，第一致动拉片30和第二致动拉片40保持定位在罐L的端壁10与罐L的周围边缘21的平面之间，而不干涉堆叠在其上的相同罐L的底部，如图2所示。
因此，这里提出的构造解决方案允许使用者/消费者选择是通过移动第一致动拉片30仅形成通气开口A1，还是也通过移位第二致动拉片40随后形成倾倒开口A2。然而，应该注意的是，两个面板中的任何一个在产生相应的开口时，完全从罐L的上壁10上拆下，而不突出到罐L的内部。
关于上面的描述，应该理解的是，对于本领域的专家来说，本发明的部件的理想尺寸关系，包括尺寸、材料、几何形状、功能、操作模式、安装布置和用途的变化，将被认为是显而易见的，并且等同于附图中示出和说明书中描述的那些关系，应该被理解为包括在本发明中。
因此，虽然这里仅示出了实施本发明的一种方式，但是应当理解，在不脱离本说明书所附权利要求中限定的保护范围的情况下，可以对部件的形状和形成进行修改。
