Description

具有包括纤维的边沿件的复合纸板容器以及生产这种容器的 方法
技术领域
本公开涉及一种复合纸板容器和一种生产该复合纸板容器的方法。
背景技术
在用于诸如婴儿配方奶粉、烟草、洗涤剂等产品的一次性容器的领域，不断需要通过最大限度地减少一次性容器的资源使用以及使容器可回收来减少此类产品的碳足迹。本文所指的一次性容器是具有由层压片材制成的管状主体的复合容器，该层压片材包括纸箱层，即主要由纤维素纤维制成的层。对于某些容器，容器的上边缘和下边缘包括连接到包装容器边缘的塑料边沿件。这为包装容器提供了令人愉悦且整洁的外观，并且容器顶部或底部也可以更耐磨。为了提供不含塑料部件的容器，容器的顶部部分和/或底部部分可替代地由管状主体的折入端部部分制成。然而，这种包装容器的外观在包装容器的底端处会稍微不那么吸引人并且耐磨性较差。
传统上，纸基材料由于被认为具有较低的形状稳定性并且相较塑料部件而言易损且不耐磨而被认为不太适合用于制造纸板容器的盖子和边沿件。也很难实现这种部件与纸板容器的主体的牢固而紧密的附接以及边沿件与容器盖之间的紧密闭合。
因此，需要为诸如食品之类的敏感商品提供具有改进的可回收性而不牺牲被包装商品的持久性或包装安全性的进一步的包装。
发明内容
上述目的可以通过根据权利要求12所述的制造复合纸板容器的方法、利用根据权利要求1所述的复合纸板容器来实现。本发明的进一步优点和有利特征在以下描述和从属权利要求中公开。
根据第一方面，本公开涉及一种用于散装固体的复合纸板容器。该复合纸板容器包括管状主体，该管状主体于底端处、在与位于管状主体的顶端处的容器顶部开口相对的容器底部开口上方被封闭。管状主体具有面向管状主体的内部的内表面和背向管状主体的内部的外表面。管状主体沿纵向方向在管状主体的底端与顶端之间延伸。复合容器包括围绕容器顶部开口和/或底部开口的边沿件，容器顶部开口具有顶部开口周边，并且容器底部开口具有底部开口周边。边沿件通过边沿件的第一连接部分沿着管状主体的端部边缘附接到管状主体的端部部分。管状主体由包括纸箱基底层的层压片材制成。边沿件是包括纸浆纤维(诸如软木纸浆纤维)的模制边沿件。边沿件通过第一粘合剂层连接到管状主体，第一粘合剂层包括热塑性粘合剂，并且布置在介于边沿件的第一连接部分与管状主体的端部部分之间的第一间隙中。第一粘合剂层以在管状主体的端部部分处每毫米容器开口周边从0.1mg起的量包括热塑性粘合剂或由热塑性粘合剂组成。
第一粘合剂层可以以在管状主体的端部部分处每毫米容器开口周边0.1mg至10mg的范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。优选地，第一粘合剂层以在管状主体的端部部分处每毫米容器开口周边0.5mg至5mg范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。第一粘合剂层可以在管状主体的端部部分处以每毫米容器开口周边1mg至5mg范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。
边沿件是包括纸浆纤维的模制边沿件，该模制边沿件可以由95％至100％的诸如软木纸浆纤维之类的纸浆纤维构成，可选地由98％至100％的纸浆纤维构成。已开发用于模制应用(诸如模制托盘和泡罩、成型或压花的盒等)的此类材料的示例例如在Billerud生产并以Billerud/>销售。类似的材料是Mondi提供的AdvantageFormable纸张。
希望为诸如食品产品之类的敏感商品提供具有改进的可回收性而不牺牲被包装商品的持久性或包装安全性的包装。然而，由于边沿件是包括纸浆纤维的模制边沿件，因此与常规塑料边沿件相比，该结构的柔性会较低，并且还会具有更为不规则的表面，这会降低边沿件与管状纸板主体之间的粘附性并由此降低容器的刚性。因此，被包装商品的持久性或包装安全性会因为可能存在较小昆虫(诸如法老蚁)穿过管状主体与边沿件之间的空间的风险而降低。然而，本发明人出人意料地发现，通过将热塑性粘合剂的量增加到对于围绕边沿件所附接的容器开口周边每毫米从0.1mg起的量，可以实现令人满意的密封性，从而允许对诸如食品之类的敏感商品进行包装。
管状主体的端部部分可以在容器顶部开口处或者在容器底部开口处。
边沿件可以经由第一连接部分连接到管状主体的内表面或外表面。第一连接部分是围绕管状主体的整个周缘延伸的周缘连接部分。第一连接部分沿着管状主体的整个端部部分连接到管状主体。为了在边沿件与管状主体之间提供增强的附接和密封，管状主体可以在面向第一连接部分的表面上——诸如在管状主体的内表面和/或外表面上——设置有诸如聚乙烯或聚丙烯层之类的热塑性层。可替代地或附加地，边沿件可以在面向管状主体的表面上设置有热塑性层。热塑性层为边沿件提供了更为规则的表面，从而增强了密封性并提高了被包装货物的持久性或包装安全性。
作为边沿件的第一周向部分的第一连接部分可以具有第一远侧边缘，并且第一连接部分的第一远侧边缘可以位于离管状主体的端部边缘一段距离处，该距离从4mm起，可选地在4mm至50mm的范围内，优选地在5mm至40mm的范围内。边沿件的第一连接部分可以是面向管状主体的内表面或外表面的纵向延伸的周向轴环。由于边沿件是包括纸浆纤维的模制边沿件，因此与常规的塑料边沿件相比，该结构的柔性和稳定性会较低。已经发现，边沿件具有位于离端部边缘一段从4mm起、可选地为4mm至50mm的距离的第一连接部分，这通过管状主体的壁为边沿件的最脆弱部分——即该连接部分或多个连接部分——提供支撑而为边沿件提供了增强的形状稳定性。
管状主体的面对边沿件的第一连接部分的周向区域可以用第一粘合剂层覆盖，该周向区域从管状主体的端部边缘朝着当在纵向方向上观察时该管状主体的相对端部边缘延伸至少4mm、可选地至少10mm。这可以为边沿件的第一连接部分提供结构支撑。
第一连接部分可以面向管状主体的内表面，并且边沿件可以包括面向管状主体的外表面的第二连接部分。边沿件还可以通过施加在管状主体的外表面上的第二粘合剂层连接到管状主体，该第二粘合剂层包括热塑性粘合剂或由热塑性粘结剂组成，并且布置在介于边沿件的第二连接部分与管状主体的外表面上的端部部分之间的第二间隙中。由于粘合剂层设置在介于第一连接部分与内表面之间的第一间隙中以及介于第二连接部分与管状主体之间的第二间隙中，因此可以实现改进的密封性和边沿件与管状主体连接的增强的稳定性。
第二粘合剂层可以以在管状主体的端部部分处每毫米容器开口周边从0.1mg起的量布置在第二间隙中。
第二粘合剂层可以以在管状主体的端部部分处每毫米容器开口周边0.1mg至10mg范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。优选地，第二粘合剂层以在管状主体的端部部分处每毫米容器开口周边0.5mg至5mg范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。第二粘合剂层可以以在管状主体的端部部分处每毫米容器开口周边1mg至5mg范围内的量包括热塑性粘合剂或由热塑性粘合剂组成。
边沿件的第二连接部分可以具有第一远侧边缘，并且该连接部分的第一远侧边缘可以位于离管状主体的端部边缘一定距离处，该距离在4mm至50mm的范围内，可选地在5mm至40mm的范围内。
边沿件可以围绕容器顶部开口并且是盖部件的一部分，盖部件包括边沿部和盖部，边沿部和盖部模制成一体，其中使一个或多个铰链部分将边沿部与盖部连接。
边沿件可以是内边沿件，并且包装容器可以附加地包括盖部件，该盖部件包括外边沿部和盖部。外边沿部件可以包括纤维并且可以与外边沿部模制成一体，其中外边沿部通过铰链部分连接到盖部，并且外边沿部件可连接到内边沿件。
复合纸板容器可以不含塑料部件，诸如塑料边沿部件、盖部件或底部部件。塑料部件是指单独的部件，而不是纸板层压材料中的层。这种复合容器无需将塑料部件与纸板容器主体分离就可以回收。
边沿件的密度可以在0.2kg/dm3至1.5kg/dm3的范围内，可选地在0.2kg/dm3至1kg/dm3的范围内，可选地在0.4kg/dm3至0.8kg/dm3的范围内。根据本公开的边沿件是模制边沿件，并且因此需要具有结构耐久性，优选地类似于塑料边沿件的结构耐久性。对于要连接到附加的边沿部的边沿部件——诸如内边沿部件和外边沿部件，这些边沿部件需要具有一定的柔性并且能够在结构上是稳定的。
边沿件可以包括U形或方边型U形的轨道部分，该轨道部分包括第一侧壁区段和第二侧壁区段以及面向管状主体的端部边缘并连接第一侧壁区段与第二侧壁区段的底部区段。第一侧壁区段可以对应于第一连接部分，或者第一连接部分可以包括第一侧壁部分。底部区段与第一侧壁区段之间的拔模角可以在0度至10度的范围内，可选地在0度至5度的范围之内，这有助于沿着整个第一侧壁区段在边沿件与管状主体的端部部分之间的紧密配合。
第一侧壁区段与第二侧壁区段之间的距离沿着整个第一和第二侧壁区段可以变化小于3mm。有助于边沿件的轨道部分与管状主体的端部部分之间的紧密配合，稳定了端部部分处的边沿件和管状主体，并提高了被包装货物的持久性和包装安全性。
边沿件可以包括L形连接部分，该L形连接部分包括第一侧壁区段和面向管状主体的端部边缘的底部区段。第一侧壁区段可以对应于第一连接部分，或者第一连接部分可以包括第一侧壁部分。底部区段与第一侧壁区段之间的拔模角可以在0度至10度的范围内，可选地在0度至5度的范围内。这有助于L形连接部分与管状主体的端部部分之间的紧密配合，从而提高了被包装货物的持久性和包装安全性。
底部区段与连接部分的远侧边缘之间的距离可以从3毫米起，可选地在7毫米至30毫米的范围内。这种连接部分有助于提高结构稳定性以及延长储存稳定性。
第一连接部分可以设置有距离元件，诸如在管状主体的纵向方向上延伸的肋，距离元件面向管状主体、诸如例如管状主体的内表面。第一连接部分可以设置有三个或更多个距离元件，诸如五个或更多个或者十个或更多个的距离元件，当在管状主体的周向方向上观察时这些距离元件平行布置。在将边沿件施加到管状主体的端部部分时，距离元件为粘合剂提供了通道并且提供了到管状主体的距离，从而在施加边沿件时防止从第一连接部分/管状主体的端部部分刮掉粘合剂，并由此有助于粘合剂的均匀涂覆。在这种情况下，在距离元件之间的位置处测量第一连接部分的拔模角。
第一连接部分可以包括第一侧壁区段和引导侧壁区段，引导侧壁区段从第一侧壁区段延伸。引导侧壁区段是与第一侧壁区段相比到管状主体的距离更大的区段。引导侧壁区段可以是倾斜壁区段，当从管状主体的端部边缘且沿管状主体的纵向方向观察时，该倾斜壁区段至管状主体的距离增加。
对于具有L形、U形或方U形横截面的边沿件，引导侧壁区段可以是倾斜壁区段，从管状主体的端部边缘且沿管状主体的纵向方向观察时，该倾斜壁区段到管状主体的距离增加。引导壁区段可以具有从2度至30度的拔模角。引导壁区段的拔模角可以大于第一侧壁区段的拔模角。
在步骤d)中，第一连接部分可以设置有距离元件，诸如在管状主体的纵向方向上延伸的肋，距离元件面向管状主体、诸如例如管状主体的内表面。
由于边沿件是由纸浆纤维制成的，因此该结构相较塑料边沿件更脆弱且柔性更小，并且还在边沿件与管状纸板主体之间产生更大的摩擦。为了降低在将粘合剂施加到第一连接部分时损坏边沿件或边缘部分的风险，边沿件可以包括从第一侧壁区段延伸的引导侧壁区段。附加地，这由于增强了用于施加粘合剂的喷嘴的通路而有助于向第一连接部分正确施加粘合剂。当将边沿件附接到管状主体时，这也是一个优点。当边沿件包括供管状主体的端部部分插入的U形或方边型U形的轨道部分时，这尤其是有利的。由于边沿件包括纸浆纤维的事实，因此需要在边沿件与管状主体之间施加增加量的粘合剂，以确保粘合剂充分填充在介于边沿件与轨道的侧壁之间的间隙中。引导部分还可以用作用于从间隙压出的粘合剂的储存器，从而保护容器的内部或外表面不被粘合剂弄脏。
根据第二方面，本公开涉及一种生产根据前述权利要求中任一项的用于散装固体的复合纸板容器的方法，该方法包括以下步骤：
a)将包括纸板基底层和热塑性焊接层的纸板层压片材弯曲成管，该管具有纵向方向和垂直于该纵向方向的径向方向，通过接合纸板材料的搭接或邻接侧边缘而在纵向上闭合该管，从而形成管状主体，该管状主体具有面向管状主体的内部的内表面和背向管状主体的内部的外表面；
b)使所述管具有预定的横截面形状；
c)于底端处、在与管状主体的顶端处的容器顶部开口相对的容器底部开口上方封闭管状主体；
d)将诸如软木纤维之类的纸浆纤维提供到模制工具中，从而形成包括纤维的三维形状的边沿部件，该纤维是纸浆纤维，该边沿件包括具有远侧边缘的连接部分；
e)将包括热塑性粘合剂的第一粘合剂层沿着管状主体的端部边缘提供到边沿件的第一连接部分和/或管状主体的端部部分，该热塑性粘合剂的量为在端部部分处每毫米容器开口周边从0.1mg起；和
f)将边沿件提供到端部部分，从而将边沿件粘合地附接到管状主体。
形成边沿件的步骤d)可以包括形成具有第二连接部分的边沿件，并且其中步骤f)可以包括在管状主体的内表面上的端部部分上提供第一粘合剂层，并且进一步在管状主体的外表面上的端部部分上提供包括有热塑性粘合剂的第二粘合剂层。
在步骤d)中，第二粘合剂层可以以在管状主体的端部部分处每毫米容器开口周边从0.1mg起的量布置在第二间隙中。
此外应理解的是，步骤e)和f)可以组合进行，使得边沿件附接到端部部分并且使得包括有热塑性粘合剂的第一粘合剂层以在端部部分处每毫米容器开口周边从0.1mg起的量注入在介于管状主体的端部部分与边沿件的第一连接部分之间的间隙中。
边沿件的密度可以在0.2kg/dm3至1.5kg/dm3的范围内，可选地在0.2kg/dm3至1kg/dm3的范围内，可选地在0.4kg/dm3至0.8kg/dm3的范围内。
在步骤d)中形成的边沿件可以包括U形或方边型U形的轨道部分，该轨道部分包括第一侧壁区段和第二侧壁区段以及面向管状主体的端部边缘的底部区段，并且其中步骤e)可以包括布置边沿件而使得底部区段面向管状主体的端部边缘。
底部区段与第一侧壁区段之间的拔模角可以在0度至10度的范围内，诸如0度至5度。
第一侧壁区段与第二侧壁区段之间的距离沿着整个第一和第二侧壁区段可以变化小于3mm。
在步骤d)中形成的边沿件可以包括L形连接部分，该L形连接部包括第一侧壁区段和面向管状主体的端部边缘的底部区段，并且其中底部区段与第一侧壁部区段之间的拔模角可以在0度至10度的范围内，诸如在0至10度范围内，可选地在0度至5度的范围内。
对于在步骤d)中形成的边沿件，第一连接部分可以包括从第一连接部分的第一壁区段延伸的引导侧壁区段，在施加该边沿件时，引导侧壁区段到管状主体的距离大于第一壁区段到管状主体的距离。
引导侧壁区段可以是倾斜壁区段，当从管状主体的端部边缘且沿管状主体的纵向方向观察时，该倾斜壁区段到管状主体的距离增加。引导壁区段可以具有从底部区段观察时成2度至30度的拔模角。引导壁区段的拔模角可以大于第一侧壁区段的拔模角。
在步骤d)中，第一连接部分可以设置有距离元件，诸如在管状主体的纵向方向上延伸的肋，距离元件面向管状主体、诸如例如管状主体的内表面。在将边沿件施加到管状主体的端部部分时，距离元件为粘合剂提供了通道并提供了到管状主体的距离，从而防止在施加边沿件时从第一连接部分/管状主体的端部部分刮掉粘合剂，并由此有助于粘合剂的均匀涂覆。
管状主体的横截面形状可以是具有圆角的改型矩形形状。应当理解的是，管状主体可以具有任何有用的横截面形状，诸如圆形、椭圆形、或者诸如三角形、正方形、五边形等任何多边形或改型多边形。
