Abstract

用于含有二氧化碳的饮料的桶，其中桶包括刚性容器，该容器包括至少两层，即由聚合物制成的第一层和纤维增强的第二层，其中，第二层在第一层外部，第二层附接到第一层。

Description

用于含二氧化碳的饮料的桶及其使用
技术领域
本发明涉及一种用于含有二氧化碳的饮料的桶及其使用。
更具体地，本发明涉及一种用于啤酒的桶或小桶，在其中啤酒可以被置于压力下，并可以从桶或小桶中分配啤酒。
背景技术
这样的啤酒桶必须满足一些技术要求。首先，啤酒必须与外部空气完全分隔开，以防止二氧化碳能够从啤酒中逸出，从而改变啤酒的味道，并且还可以防止空气中的氧气能够进入啤酒，因为这样也可能在很大程度上不利地影响味道。例如，根据类型，即使1000ppb(十亿分之几)的氧气含量也可能对味道有害。
在啤酒第一次使用之前以及啤酒的一部分已经被倒出后，但是桶中仍然存在将来要用的部分，这种与外部空气的分隔都是重要的。
啤酒桶满足这些技术要求的程度取决于在啤酒小桶中使用的各种壁的气体渗透性，具有较高扩散屏障的壁因为其更厚或由更昂贵的材料制成而通常价格更高。
其次，容器具有机械功能，即抵抗内部压力，而不会变形或损坏，这是将食品从容器中分配出来所必需的。
当然在桶中这种压力可以很高，其中用于排出啤酒的压力介质(例如二氧化碳)，在这些桶在温暖的环境中时已经存在，在填充的桶的运输过程中这很容易发生。在某些条件下，该压力可以达到10巴。还必须考虑到的是，这种桶在运输过程中可能掉落，从而可能暴露于来自外面的较高力。
不言而喻，这种啤酒小桶必须尽可能廉价地制造，因此目前的金属桶被认为太昂贵且沉重，当然，在运输距离相对较长和/或缺乏供应链良好协调的情况下，重复利用是困难的。
聚丙烯或聚乙烯的啤酒桶是已知的。然而，它们对高压力抗性有限，因此特别是在更高压力下，它们必须用非常厚的壁制造。
同样，在使用过程中，压力抗性迅速下降，因为随着压力的每次显著变化，例如在如上所述的暂时的较高温度期间，以及重复使用的重复加压，都会发生部分弹性和部分不可逆的塑料变形，可导致在重复使用几次后危险缺陷。
这些材料对于二氧化碳和氧气也是相对可渗透的，因此必须采取特殊措施来筛选啤酒。
目前不存在便宜的、具有良好的二氧化碳和氧气保护、可以抗高压力、并且可以回收数十次的啤酒桶。
发明内容
本发明的目的是通过提供一种用于含有二氧化碳的饮料的桶，来提供对于上述和其他缺点的解决方案，其中桶包括刚性容器，该容器包括至少两层，即由聚合物制成的第一层和纤维增强的第二层，其中第二层在第一层外部，并且，第二层附接到第一层。
这种桶制造便宜，并且非常适合抵抗高压力。
由于第二层，其不能膨胀，以及第一和第二层之间的良好附接，不会发生第一层的塑料变形，从而可以重复使用桶。这里，第二层可以附加在整个第一层上，但是第二层也可以是不完整的第二层，其仅附加在破裂风险最大的地方。
在优选实施例中，桶还包括位于刚性容器内部的柔性容器。
优选地，刚性容器包括第一出口，柔性容器包括第二出口，第二出口设置有连接到第一出口的连接件，并且，连接件还设置有龙头或用于龙头的接头。
柔性容器现在可以用含二氧化碳的饮料填充，并且刚性容器和柔性容器之间的空间用压力介质填充，从而使得由于柔性容器的压缩，饮料可以被排出桶。
在另一个优选实施例中，桶设置有屏障层以防止氧气从外部扩散到内部，以及二氧化碳从内部扩散到外部。
这可以通过对第一或第二层或是在两者之间的界面设置屏障层来实现，例如，薄金属层。
从WO 2012/167333中已知，例如，可以通过使用放置在彼此中的两个柔性容器来实现，内柔性容器旨在容纳饮料，外部柔性容器旨在通过压力介质推挤刚性容器的内部，从而降低了用于压力介质的刚性容器的渗透性，并由此这些柔性容器中的一个或两个由用于二氧化碳和氧气的屏障材料制成。
在另一优选实施例中，第一层基本上由可注射模塑的聚合物制成，优选地为可以是HDPE和LDPE的聚乙烯，或聚丙烯。因此，第一层通过注射模塑的方法便宜的生产。
此外，所述塑料的优点在于，即使压力升高到高于桶可以应付的压力，桶也不会爆炸，而是会塑形变形和局部撕裂，从而以相对受控的方式降低压力，从而防止潜在的危险爆炸。
在另一个优选实施例中，第二层设置有围绕第一层缠绕的一个或多个增强纤维。这意味着有关的增强纤维各至少完全绕桶一次。
优选地，存在或只有一个或几个长的重复绕桶的增强纤维。
因此，因为增强纤维具有高拉伸强度，桶对来自内部的压力的抗性更好。
因此，优选地将增强纤埋设在粘合剂中，粘合剂优选地为聚丙烯或聚乙烯。由于粘合剂，获得了到第一层的良好附接。
在另一优选实施例中，桶设置有第三层，该第三层由塑料制成，第三层在第二层外部。
这样的第三层用于保护第一和第二层免受来自外部的冲击和其他可能的损坏。因此，也可以给桶能够实现稳定放置在表面上以及实现稳定的桶的堆叠的形状，如果纤维增强的第二层是外层这将是困难的甚至是不可能的。
第三层还具有装饰功能。
第三层优选地由聚乙烯或聚丙烯通过注射模塑制成。
第三层可以附接到第二层，但是优选地，第三层不附接到第二层，并由可拆卸地紧固在一起的两个或多个部件构成。
这意味着为壳体形式的第三层是容易附加的，并且在损坏的情况下也容易更换。考虑到桶的重复使用性，这种损坏是可以预期的，因为这种桶经常移动从而容易被撞击或掉落。
本发明还涉及如上描述的用于储存含有二氧化碳的饮料、特别是啤酒的桶的使用。
附图说明
为了更好的示出本发明的特征，下面参考附图，通过示例而不限制其特性，描述根据本发明的桶的优选实施例，其中：
图1示出了根据本发明的桶的横截面；
图2示出了以更大比例的图1中的桶的标示为F2的部分；
图3示出了图1的桶的生产步骤。
具体实施方式
图1和图2中所示的桶1基本上由刚性容器2和附加在其中的具有两个柔性容器4、5的连接件3组成。
刚性容器2由三层构成，即，第一内层6、第二中间层7和第三外层8。
第一层6由高密度聚乙烯HDPE制成，并具有约3mm的厚度。第二层7是复合层，也具有约3mm的厚度，由长玻璃纤维9形成，该玻璃纤维围绕第一层6缠绕，并埋设在低密度聚乙烯LDPE 10中。第二层7被熔合到第一层6上，如此使得这两层6、7非常牢固地附接在一起。
第三层8也由HDPE制成，并相对松散地附加在第一层6和第二层7周围，从而使得在第二层7和第三层8之间存在一些空间11。第三层8由两部分组成，即基部件12和顶部件13。
基部件12和顶部件13通过螺钉14紧固在一起，在周边区域周围。
刚性容器2具有第一出口15，该第一出口由第一层6形成，并设置有外部螺纹。
在该示例中，不必须的，刚性容器2具有31升的内部容积。
连接件3设置有两个柔性容器，即内柔性容器4和外柔性容器5。柔性容器4、5各自足够大以填充刚性容器2内的空间。
柔性容器4、5被制造成具有第二出口16的袋子，连接件3紧固到第二出口16。柔性容器4、5由具有金属化层的多层箔制成，以便不渗透二氧化碳和氧气。
连接件3设置有内螺纹5，该内螺纹适配在刚性容器2的外螺纹上，并设置有用于压力介质源的接头17，在该示例中，压力介质源为二氧化碳气缸，从接头17到空间19设置通道18，空间19在内柔性容器4和外柔性容器5之间。
管道20被紧固到连接件3上，连接件位于柔性容器4、5中。龙头可安装在连接件3的顶部上。
图1中的桶1的使用是简单的，如下所述。
通过将管道20和两个柔性容器4、5滑动穿过第一出口15，并将连接件3拧紧到刚性容器2的第一出口15上来组装桶1。
使用特殊的填充头，现可通过连接件3用啤酒填充内柔性容器4，填充啤酒的量使得桶1几乎完全填满，在该示例中，为30升啤酒。
由此获得了啤酒的长期保存期限，由于两个柔性容器对二氧化碳和氧气的低渗透性，没有二氧化碳能够从啤酒中逸出，没有氧气可以从外部空气扩散到内部。
当桶1被必须使用的啤酒填充时，二氧化碳胶囊连接到为此设置的接头17，从而使得二氧化碳可以流入内柔性容器4和外柔性容器5之间的空间19中，并且该空间19可以置于压力下。外柔性容器5因此被推靠在刚性容器2的第一层6上。龙头也被附加在连接件3上。
当龙头打开时，由于管道20施加的压力，啤酒流到外部。
当桶1为空时，具有柔性容器4、5的连接件3可以被移除和破坏。连接件3和柔性容器4、5的组合几乎不可能清洁的，从而不可能重复使用。
剩余的刚性容器2进行损坏检查。如果基部件12损坏，其可以通过拧下螺钉14、附加新的基部件12和再次拧紧螺钉14来容易地更换。
如果顶部件13损坏，其可以以相似的方式更换，由于第二层7和顶部件13之间的空间11，第一层6和第二层7可以从顶部件13中滑出，并可滑入到新的顶部件13中。
刚性容器2现在可以设置有具有新柔性容器4、5的新连接件3，并再次填充啤酒。
刚性容器2可以如下生产。
将稍后形成第一层的单独的容器6通过注射模塑生产。第三层8的顶部件13和基部件12也通过注射模塑单独地生产。
所述单独的容器16通过绕线机21用玻璃纤维9包裹，该玻璃纤维9首先被引导通过熔融LDPE10浴22。这在图3中示出。
因此，为了与刚性容器2的第二层7一起形成，多个线圈层被横向放置。
由于玻璃纤维9上的LDPE10在缠绕时仍然是熔融的，在单独的容器6和缠绕层7之间产生非常好的附接。这里必须注意各种部件的定位，以使得熔融的LDPE10浴22和绕线机22之间的距离不会太大到当LDPE10在围绕单独的(容器)缠绕时已经固化。
作为熔融的LDPE10的替代，可以使用粘结剂、树脂和类似物来实现对单独的容器6的良好附接。
然后，等同于第一层6和第二层7的缠绕单独的容器在顶部件13中滑动，之后通过附加基部件12完成第三层。
本发明绝不限于在附图中示出并被描述为示例的实施例，但是根据本发明的桶可以以各种形式和尺寸实现，而不脱离本发明的范围。
