本发明的公开内容涉及一种预成型件以及用于对容器进行吹塑成型的方法。
背景技术
吹塑成型是公知的用于制造容器(例如但不限于用于饮料的瓶子)的技术。在该技术中,例如通过注塑成型来模制塑料预成型件。该预成型件被加热到塑料熔融温度以下的温度。吹塑成型工具被插入到预成型件,其置于吹塑成型模具的内侧,该模具具有预期容器的形状。利用吹塑成型工具,预成型件被拉伸,然后预成型件对着模具的内部表面被吹塑为预期形状。

在文献WO 2008083782中,所显示的容器具有通过利用焊接方法(例如超声焊接或激光焊接)设置在颈部部分中的阀组件。该阀组件在对容器进行吹塑成型之后被焊接到颈部区域内。
在文献WO 2008098937中,所显示的容器具有通过利用激光焊接方法设置在颈部部分中的阀组件。通过将激光束经过颈部部分的壁部引导到阀组件的环形部分上,从而在对容器进行吹塑成型之后将该阀组件焊接到颈部区域内。
希望提供一种用于制造吹塑成型的容器的替代的方法和预成型件,该容器具有附接其上的盖子元件。
发明内容
在第一个方面,本说明书涉及一种用于对容器进行吹塑成型的预成型件,其中在由所述预成型件对容器进行吹塑成型之前,盖子元件附接到所述预成型件。
在另一个方面,本说明书涉及一种用于由预成型件对容器进行吹塑成型的方法。所述方法能够包括首先将盖子元件附接到所述预成型件、然后从所述预成型件而吹塑成型出所述容器的步骤。
在又一个方面,本说明书涉及一种由本说明书的预成型件或者利用根据本发明的方法步骤吹塑成型的容器。
附图说明
在从属权利要求书中进一步公开了预成型件和方法的其它方面。为了使本发明所公开的主题更为清楚,下面将参考只是示意性地表示的附图来讨论预成型件、方法和容器的实施方案。在这些附图中:
图1示意性地显示了预成型件的第一实施方案;
图2示意性地显示了盖子元件的横截面图和部分仰视图;
图3示意性地显示了图1中的预成型件,其具有在颈部部分处附接的盖子元件;
图4示意性地显示了预成型件的第二实施方案;
图5示意性地显示了预成型件的第三实施方案;
图6示意性地显示了预成型件组件;
图7示意性地显示了另一个预成型件组件;
图8示意性地显示了根据本说明书制造的容器;并且
图9示意性地显示了根据本说明书制造的容器的替代实施方案,其具有连接装置。
具体实施方式
在本说明书中,相对于由预成型件吹塑成型(例如拉伸吹塑成型)的塑料容器描述了实施方案,其中预成型件能够例如由注塑成型或压出来进行制造。这些容器能够例如但不限于用来存储饮料,所述饮料例如但不限于碳酸饮料。显然,容器能够由其它材料制成,例如塑料混合物、塑料和金属的组合物,例如金属箔、清除剂等等。这些实施方案仅作为示例性实施方案公开,并且不应被认为以任何方式对本发明形成限制。
在本说明书中,注塑成型应当被理解为至少包括但不限制于拉伸注塑成型,其中预成型件被加热、在长度方向上被拉伸并且被吹塑为预期形状。在长度方向上拉伸的过程中,预成型件能够已经在一定程度上被吹塑。
在本说明书中,还可以是型坯的预成型件应当被理解为至少包括但不限制于由塑料注塑成型的元件,该元件将要被吹塑为吹塑成型的容器。在本说明书中,预成型件将描述为用于对基本具有瓶子形状的容器进行吹塑成型,该容器包括颈部部分、本体部分和底部部分,但是对于本领域技术人员显而易见的是,利用落入相同创造性概念之内的不同形状的预成型件能够制成不同形状的容器。预成型件可以是单层或多层。多层预成型件能够利用公知技术来进行制造,这些公知技术例如但不限制于复合注塑、复合压出或二次成型。多层预成型件能够具有分层的一层或更多层。
在本说明书中,像如大约和基本的表述应当理解为意指其所指的给定值的变化范围允许落入给点限值之内,该变化可以为给定值的至少5%,优选为至少10%,并且更优选为至少15%。
在本说明书中,将讨论由PET或PET混合物制成的预成型件和容器。然而,根据本发明的预成型件和容器还能够由不同材料、材料的混合物或组合物制成,这些材料例如但不限制于聚丙烯或聚苯乙烯、PEN、聚乙烯、聚碳酸脂、PBT、以上材料的混合物或其组合物。在PET或PET混合物的情况下,在这方面,标准PET必须理解为至少包括PET,该PET未添加用于防止该PET在形成预成型件(例如对预成型件进行注塑成型)的过程中结晶的添加剂。
在本说明书中将参考用于保持并分配饮料特别是碳酸饮料(例如啤酒和软饮料)的容器。然而,利用根据本说明书的容器能够存储并分配其它内容物。
在本发明中,预成型件可以由塑料材料形成,该塑料材料能够被拉伸吹塑成型为具有相对薄壁或组合壁的容器,其中预成型件基本为无定形的,而瓶子至少部分为晶体的。优选地,预成型件由基本不含防结晶添加剂的材料形成,例如乙二醇。已经考虑到,这样的添加剂在对基本为无定形的预成型件进行注塑成型时会是有利的,但是这些添加剂保留在吹塑得到的容器中,这对于容器的强度和/或硬度是有害的。预成型件优选为被注塑成型为具有充分小的壁厚,以便基本防止塑料材料进行结晶。
对于由预成型件拉伸吹塑成型的容器,其内部容积特别是容积在3升以上,预成型件的开口相对大,例如为2cm或更大。设置具有更小开口的垫子元件;使得能够容易地对更小尺寸的阀或阀组件进行设置。例如,当使用标准溶胶类型的阀、喷雾器类型的阀等等例如用于筘位时,这就是有利的。
在图1中显示了以通用公知方法吹塑成型的预成型件1。图1的左侧显示了预成型件的横截面图,右侧显示了侧视图。预成型件1能够包括具有封闭的第一端3的基本圆柱形的壁部2以及处于相对的第二端5处的颈部部分4。内部容积6从颈部开口7延伸到内部空间8内。内部空间8大部分由内部表面9限定。环绕内部空间8的壁部2能够具有壁厚Tw,该壁厚Tw能够例如与颈部部分4的厚度Tn相同或大于厚度Tn。在颈部部分4的外侧10上能够设置抓持元件11,例如一个或两个凸缘12以及/或者螺纹13。该凸缘12或每一个凸缘12能够基本垂直于预成型件1的纵向轴线L延伸。如果存在一个以上这样的凸缘12,则其能够基本彼此平行地延伸。在图1的实施方案中显示了一个这样的凸缘12。凸缘12是通用的,并且能够用于握持预成型件1和/或由其吹塑的容器23。另外,这些凸缘能够用于使颈部部分4具有刚性,以便尽可能好地维持其形状和尺寸。另一个方面能够是,这些凸缘允许其它元件附接到颈部部分,例如但不限于盖子、分配机构、顶部环结构等等。能够包括的实施方案具有不同尺寸的凸缘。
在图1的实施方案中,内部表面9直接且连续地延伸到颈部部分4内。除了在第一端3处的部分14(其能够是基本球形或成形为用于形成花瓣形的底部)之外,内部表面9能够是基本圆柱形的。颈部部分4在第一端3处能够具有基本平坦的圆形端部表面15。在另一个实施方案中,颈部部分能够具有不同形状的端部表面15,例如但不限于部分或完全为圆锥形、凹陷形或齿形。在另一个实施方案中,端部表面能够具有不同于圆形的形状,例如但不限于椭圆形、卵形、方形、矩形或多边形。
在图2中显示了盖子元件16的局部横截面。在该实施方案中,盖子元件16基本为环形,其具有周缘环17和中心开口18。中心开口18能够设置在从环17延伸或延伸穿过环17的管状部分19中。在这样的实施方案中,管状部分19的外部表面能够用于将元件附接到盖子元件16的,如图2中以虚线示意性地显示的,这样的元件例如但不限于筘位到部分19、盖子、通风设备等等的阀20。盖子元件16能够由类似于预成型件1的塑料材料的塑料材料制成。在另一个实施方案中,盖子元件16能够由不用于预成型件材料的材料制成。在一个实施方案中,盖子元件16能够部分地或整个地由金属制成。在示例性实施方案中,预成型件和盖子元件两者均能够由PET或PEN或至少包含PET或PEN的混合物制成。在一个实施方案中,这样的混合物能够包括至少50重量%的PET和/或PEN。在进一步的实施方案中,混合物能够包括至少75重量%的PET和/或PEN。在一个实施方案中,预成型件1和/或盖子元件16能够由具有CO2和/或O2屏蔽属性的塑料材料制成。预成型件1能够具有多个层,其一个层特别是内部层能够至少部分地与预成型件1的其它层可脱离。在一个实施方案中,预成型件1和盖子元件16能够由可以焊接或胶结的材料制成。
在图3中显示了预成型件1,其具有附接在颈部部分4处的盖子元件16。在该实施方案中,盖子元件16在端部表面15上永久地设置有环17。在一个实施方案中,盖子元件16能够通过焊接附接到表面15。在一个实施方案中,焊接能够通过超声焊接来实现。在另一个实施方案中,焊接能够通过选自超声焊接、激光焊接、摩擦熔接、旋转熔接或压力焊接构成的集合的焊接技术来实现。在又一个实施方案中,盖子元件16能够通过胶结连接到预成型件1。在另一个实施方案中,盖子元件16能够通过其它手段永久地或可松开地连接到预成型件1,这些手段例如但不限于卡扣连接、压配合、摩擦锁定、螺纹连接、卡口锁定或用于连接两个元件的领域中公知的其它这样的手段。
正如从图3中能够看到的那样,盖子元件16允许进入到预成型件1的内部空间6内。在一个实施方案中,进入到内部空间6的入口能够经过盖子元件16,特别是经过其中的开口18。该入口能够对于吹塑成型工具21是可得到的,如图3中以虚线示意性地显示的。这样的成型工具21能够例如是具有纵向轴线Lt的元件,其在使用的过程中基本与预成型件1的纵向轴线L重合。能够对着预成型件1的第一端3推动前进端22,其能够被加热到预成型件1的塑料材料的熔融温度以下的温度,但是该温度要足够高以使材料变软,从而能够在纵向方向上拉伸预成型件1。然后,诸如空气的气体能够被压迫经过工具22并压迫到预成型件的内部空间6内,从而将预成型件1吹胀为预期形状和尺寸的容器23。在一个实施方案中,工具21的外部表面在吹塑之前能够抵靠预成型件的内壁。在另一个实施方案中,工具21的外部表面能够至少部分地与预成型件1的内壁隔开。
在本说明书的一个实施方案中,首先对预成型件1进行注塑成型。盖子元件16能够单独地进行制造,例如通过机械加工、挤压或注塑成型来制造。在不同的实施方案中,盖子元件16能够与预成型件一起形成,例如与可收缩芯部一起注塑成型,或者按照两种或更多种成分(2K)的注塑成型工艺进行注塑成型。在又一个实施方案中,盖子元件16能够铰接到预成型件,例如铰接到其颈部部分4,并且/或者,如图4所示,阀20能够铰接到环部17,并且在注塑成型并冷却之后被压迫在颈部部分的开口上。在进一步的实施方案中,盖子元件16能够以不同方式安装在颈部部分4上,例如通过焊接(例如旋转熔接、超声或激光焊接、常规焊接)、螺纹连接、卡口锁定、卡扣元件(例如卡扣环或卡扣钩)或者压配合。在另一个实施方案中,盖子元件能够胶结到预成型件。盖子元件16能够安装或设置在制成预成型件1和/或盖子16的装置之内。
在将盖子元件16安装到预成型件1之后或者直接在其之前,预成型件1能够运动到吹塑成型台,在吹塑成型台的位置处,预成型件1能够被吹塑为预期的容器23,例如如图8所示。然后,容器23能够运动到填充台,在该处能够以公知并适合的方式将饮料喷注到容器内。预成型件1优选为在吹塑成型之前特别是在从一个或更多个吹塑成型装置运走之前具有盖子元件16。这就使得制造更为容易,并且免去了运走完全甚至部分地被吹塑的但是远离空气的清空容器,例如瓶子或桶,其将是环境不友好的。而且,通过在填充之前特别是在其运送到瓶子之前在预成型件上设置盖子16,盖子元件16不必单独地进行存储及运送,并且不必在潮湿或者可能不利环境下完成盖子元件16的设置。
在另一个台中用饮料填充容器23之后,其它元件能够增加到容器23,例如对容器23进行封闭的封闭件或者阀或阀组件20,例如但不限于饮料阀和气体阀的组合。这样的阀组件能够是公知类型的阀组件,例如Sankey类型或平头类型的组件。在另一个实施方案中,诸如竖管26和连接件27的分配设备能够设置在盖子16中,例如如图7和8所示,从而使容器23连接到分配设备30,例如如图8所示,用于对饮料进行分配。这样的分配设备例如通过文献EP 1003686或WO2004/050539或EP 1626925是公知的。其它分配设备能够例如是具有汲取头的调节设备,以便连接到容器23的颈部4,用于将诸如CO2的压力气体导入到容器内,并且允许从容器分配饮料,例如分配到饮料机、汲取栓30A等等。在另一个实施方案中,诸如溶胶类型阀的阀20能够设置在盖子16中,用于对饮料进行分配,并且在替代实施方案中还用于将压力气体导入到容器23内。这样的阀例如通过文献WO2008/048098而公知。
在一个实施方案中,预成型件1能够设计用于对容器23进行吹塑成型,该容器23的含量在1升和10升之间,例如在2升和6升之间。在一个实施方案中,容器23能够具有大约5升的含量。在一个实施方案中,预成型件1能够设计用于对容器23进行拉伸吹塑成型,该容器23的含量在10升以上,例如在10升和50升之间。在一个实施方案之间,容器能够具有的容量在15升和30升之间,例如为大约17升至20升。根据本发明的预成型件1能够由单一材料制成,例如但不限于PET、PEN、PP、PS、PC或另一种热塑性材料和/或结晶和/或可拉伸吹塑成型的塑料材料或这样的材料的组合。在另一个实施方案中,预成型件能够是多层的,包括诸如塑料或塑料混合物的相似或不同的材料的层。多层瓶子在本领域是公知的,并且在此将不再展开讨论。多层瓶子以及用于这样的瓶子的分配设备的实例公开于文献WO 92/012926中。该申请的内容通过引用纳入本文,至少将其中公开的分配设备、瓶子和材料纳入本文。
预成型件1能够具有颈部部分4,该颈部部分4具有垂直于纵向轴线A-A的内部横截面,该横截面的表面区域由具有直径D的圆形区域形成或者相当于具有直径D的圆形区域,该直径D在2cm以上,例如为在2和10cm之间的直径,更特别是在3和6cm之间,例如为大约49mm。盖子元件16能够具有中心开口18,该中心开口18具有的内部表面区域由具有直径D1的圆形表面形成或者相当于具有直径D1的圆形表面,直径D1例如在0.5和6cm之间,例如在0.5和4cm之间,该面积小于颈部部分4的开口7的面积。开口18能够使圆形的,并且能够设计为具有阀,例如配合在开口18中或开口18上的溶胶阀20。在另一个实施方案中,盖子元件16能够具有不同的开口18,例如并排的两个开口,从而例如在一个开口18中能够配合分配元件,例如具有或不具有竖管26的阀20,竖管26用于分配容器1的内容物,例如饮料,例如啤酒,而在另一个开口18A中能够附接气体入口,例如CO2源或空气泵31。
在一个实施方案中,预成型件能够被注塑成型,之后将盖子元件16设置在预成型件1或预成型件组件的其中一个预成型件上和/或预成型件1或预成型件组件的其中一个预成型件中。然后预成型件能够被转移到装瓶线,其中预成型件在线被吹塑成型并且例如被填充饮料,例如但不限于啤酒。在一个实施方案中,随后,阀组件20或分配组件30或其一部分能够被置于开口18中和/或开口18上。
在图4中示意性地显示了预成型件1的横截面,显示了形式为环17的盖子元件16,其具有例如经由集成的铰链32附接到盖子元件16的阀20。在该实施方案中,环17安装在预成型件1上,例如焊接到其上,其中阀20被折叠远离中心开口18,使得容器23能够由其吹塑成型得到,并且填充管道21能够经过所述开口18而被导入到容器23,在能够将阀20折叠到开口18内之后,在该处封闭容器23。在所示实施方案中,阀20被包围在夹持管中,其能够被夹持到开口18内,如图4中左侧示意性地所示。在由预成型件对容器23吹塑成型并且对容器23进行填充之后,阀20优选为被推动到开口18内。在图4中示意性地显示了容器的肩部部分23A。
在图5-7中显示了预成型件组件31,其包括第一预成型件1A和第二预成型件1B。第一预成型件1A能够插入到第二预成型件1B,或者反过来。在替代实施方案中,第一预成型件1A和第二预成型件1B中的其中一个能够插入两个预成型件1A、1B中的另一个当中或另一个上。预成型件1A、1B能够由相同或不同的材料而被注塑成型或者分离地形成。预成型件1A、1B能够具有前述预成型件的某些属性或全部属性。
