Description

一种用于制造液体包装容器的胚料及其包装容器 技术领域
本发明涉及一种用于制造液体包装容器的胚料及其包装容器，尤其涉及包装技术领域。
背景技术
用于盛放果汁、牛奶以及酸奶等液体的容器通常采用一次性材质的软质包装盒，如由包含纸层在内的多层材料压制/粘制而成的包装材料基于预先设置的折痕所形成的软质包装盒。
现有的软质包装盒的外部形状通常为长方体(正方体被视为是一种特殊的长方体)或者人字屋形状(即上部为人字形且下部为长方体，有时也被称为新鲜屋等)。
现有的软质包装盒的侧表面通常有四个侧壁(如两个相对较宽的侧壁和两个相对较窄的侧壁)，且包装盒的上端面也有密封缝，使得用于***吸管的圆形口只能设置在密封缝的一侧，如果要安装瓶盖，由于密封缝的存在，也无法将瓶盖黏贴在上端面的中间位置，而且瓶盖的尺寸也受到限制。
发明内容
本发明旨在提供一种用于制造液体包装容器的胚料及其包装容器，能够克服现有的软质包装盒存在的问题。
第一方面，本发明提供一种用于制造液体包装容器的胚料，包括：包装材料，包装材料由四条水平折痕分成五个横向区域，即第一折叠区域、第一侧壁区域、第二折叠区域、第二侧壁区域和第三折叠区域自上而下依次设置；第一折叠区域设置有第一下端面区域、第一翻折区域和第二翻折区域，第一翻折区域和第二翻折区域分别设置在第一下端面区域的左右两侧；第二折叠区域设置有上端面区域、第三翻折区域和第四翻折区域，第三翻折区域和第四翻折区域分别设置在上端面区域的左右两侧；第三折叠区域设置有第二下端面区域、第五翻折区域和第六翻折区域，第五翻折区域和第六翻折区域分别设置在第二下端面区域的左右两侧；且第一下端面和第二下端面完成拼接后与上端面形状和大小均一致；包装材料的上下两侧和左右两侧设有用于形成密封缝的密封折痕；上端面区域用于形成上端面，第一下端面和第二下端面共同拼接组成下端面，第一侧壁区域和第二侧壁区域共同拼接成侧壁，以形成一密闭包装容器。
进一步地，本坯料的上端面区域、第一下端面和第二下端面均为矩形，且矩形的左右两边为竖直折痕。
进一步地，本坯料的第一侧壁区域和第二侧壁区域内还设置有第一辅助折痕和第二辅助折痕；竖直折痕与水平折痕的交点为第一点，每个第一点延伸出两条第一辅助折痕，从所述上端区域内的第一点延伸出的第一辅助折痕的末端延伸出沿竖直方向设置的所述第二辅助折痕，并连接与之对应的从所述第一下端面区域和所述第二下端面区域的第一点延伸出来的第一辅助折痕。
进一步地，本坯料的同一个第一点延伸出的两条第一辅助折痕沿与之对应的竖直折痕对称设置。
进一步地，第一翻折区域还设置有翻折折痕，本坯料的第一翻折区域完成翻折后，位于第一翻折区域的水平折痕和竖直折痕重合；第二翻折区域、第三翻折区域、第四翻折区域、第五翻折区域和第六翻折区域内也对应设置有翻折折痕。
进一步地，本坯料的第二折叠区域设置有用于插吸管的圆形标记或用于装瓶盖的瓶盖标记。且圆形标记或瓶盖标记区域的坯料厚度薄于其他区域。
进一步地，本坯料的瓶盖标记设置在第二折叠区域的正中心。
进一步地，本坯料的折痕通过压制或者刻画形成。
进一步地，本坯料的包装材料由外到内依次包括：PE层、粘合层、纸层、PE层、粘合层、铝箔层、粘合层、PE层以及PE改性层。
另一方面，本发明还提供一种用于盛装液体的包装容器，由任一前述的坯料制成。
进一步地，本包装容器的下端面由第一下端面区域或第二下端面区域的一侧坯料内表面与另一侧坯料外表面或内表面粘合。
由于上端面由设置于第二折叠区域的上端面区域一次成型，无需通过密封缝密封成型，所以上端面平整，且没有密封缝，于是可以安装更大的瓶盖，并且可以将瓶盖或者用于插吸管的圆形标记设置在上端面的正中间位置，使得包装容器更加美观。
通常坯料需要先经过外形图案印刷，再进行折痕的压制，最终成型、并罐装液体，本发明提供的坯料采用对面密封，不须考虑印刷图案对准率，有效提高了包装容器的产品质量。且下端面的密封缝可以不用压制密封折痕，便可进行密封，可节约一道工序，且外形更为美观。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参考图1，本实施例一所述用于制造液体包装容器的胚料，包括：包装材料，包装材料由四条水平折痕100分成五个横向区域，即第一折叠区域1000、第一侧壁区域2000、第二折叠区域3000、第二侧壁区域4000和第三折叠区域5000自上而下依次设置；第一折叠区域1000设置有第一下端面区域1100、第一翻折区域1200和第二翻折区域1300，第一翻折区域1200和第二翻折区域1300对称设置在第一下端面区域1100的左右两侧；第二折叠区域3000设置有上端面区域3100、第三翻折区域3200和第四翻折区域3300，第三翻折区域3200和第四翻折区域3300对称设置在上端面区域3100的左右两侧；第三折叠区域5000设置有第二下端面区域5100、第五翻折区域5200和第六翻折区域5300，第五翻折区域5200和第六翻折区域5300对称设置在第二下端面区域5100的左右两侧；包装材料的左右两侧设有用于形成密封缝的密封折痕200；上端面区域3100用于形成上端面1，第一下端面1100和第二下端面3100共同拼接组成下端面2，第一侧壁区域2000和第二侧壁区域4000共同拼接成侧壁，以形成一密闭包装容器。坯料的上下两侧还可以设置用于形成密封缝的密封折痕200。
由于坯料的上下两侧未设置有密封折痕200，在进行密封时需要将坯料一侧的内表面与另一侧的外表面粘合从而进行密封。当然，也可以在上下两侧设置密封折痕200，密封 时将坯料上下侧的内表面粘合从而进行密封。
由于上端面直接由上端面区域3100成形，未经过拼接、缝合，所以可以将用于***吸管的圆形标记或者瓶盖标记设置在上端面1的正中心，同时只要在不超出上端面1尺寸的范围内，可以根据实际使用需要安装尺寸更大的瓶盖，例如需要盛装老酸奶等黏稠度较大的饮料时，需要配合勺子食用，此时安装一个大尺寸的瓶盖，使得勺子可以伸入瓶盖的开口，从而食用其中的食物。圆形标记或者瓶盖标记区域内的胚料通常薄于其他区域的胚料，以易于被吸管穿透以及方便设置瓶盖。当然除了设置在上端面1的正中心，也可以将圆形标记或者瓶盖标记区域设置在其他位置。
参考图3和图4，通常情况下，包装容器的上端面1及下端面2为矩形，所以上端面区域3100、第一下端面区域1100和第二下端面区域5100均为矩形，在上端面区域3100、第一下端面区域1100和第二下端面区域5100的两侧设置有竖直折痕300，且为了制造方便及美观，第一下端面区域与第二下端面区域在完成拼接后形成的下端面2与上端面1区域的大小及形状一致。也可以根据实际需要，设计成上大下小或者上小下大的外形，仅需调整上端面区域3100、第一下端面区域1100和第二下端面区域5100所对应的矩形尺寸即可。当然此处所述矩形包含正方形这一特殊情形。
在第一侧壁区域2000和第二侧壁区域4000都设置有用于辅助成型的第一辅助折痕400和第二辅助折痕410，竖直折痕300和水平折痕100交汇点为第一点3，每个第一点3都延伸出两条第一辅助折痕400，从位于上端面区域3100内的第一点3所延伸出的第一辅助折痕400的末端延伸出第二辅助折痕410，第二辅助折痕410沿竖直方向设置，并分别连接从第一下端区域1100和第二下端区域5100内的与之对应的第一点3延伸出来第二辅助折痕410连接。参考图2，使得包装容器获得钻石型，并且更易成型，提高生产效率。同时可以将从同一第一点3延伸出的两条第一辅助折痕400对称设置，从而可以获得更为美观的外形。
第一下端面区域1100还设置有翻折折痕500，从第一点4延伸出，在成型时，由于翻折折痕500的存在，使得按照翻折折痕500进行折叠后，与之对应的水平折痕100和竖直折痕300重合，从而实现局部成型，同样的，在第二翻折区域1300、第三翻折区域3200、第四翻折区域3300、第五翻折区域5200和第六翻折区域5300内的对应位置也设置有翻折折痕500。
本实施例的胚料通常为多层材质，所有折痕通过压制或者刻画形成。该胚料包括七层材质，且这七层材质由外(形成包装容器后的包装容器外侧)到内(形成包装容器后的包装容器内侧)依次为：PE层、粘合层、纸层、PE层、粘合层、铝箔层、粘合层、PE层以 及PE改性层(注：用于插吸管的圆形标记区域或用于设置瓶盖的区域内的胚料所包含的材质层数通常少于七层)。本实施例不限制胚料所包含的材质的层数以及各层材质所采用的具体材料等。
参考图2，本实施例2所述的包装容器由图1所示的坯料形成，形成包装容器的过程可以为：坯料的上下两侧未设置密封折痕200时，由一侧坯料的内表面与另一侧坯料的外表面或内表面粘合形成密封缝，从而实现密封；若坯料的上下两侧设置有密封折痕200，则将一侧坯料的内表面与另一侧坯料的内表面粘合形成密封缝，从而实现密封，将下端面2密封好后，再对坯料两侧的密封折痕200进行密封形成密封缝，罐装液体可以在任意一侧密封缝未完成密封前进行罐装，也可以在任意一条密封缝预留罐装口，完成罐装后再将罐装口进行密封，罐装液体时机的选择对本发明的保护范围不起限制作用。接着对当前形状的包装盒进行笼形，分别对第一折叠区域1000的第一翻折区域1200和第二翻折区域1300，以及第三折叠区域5000的第五翻折区域5200和第六翻折区域5300进行翻折，使得第一下端面区域1100和第二下端面区域5100共同拼接形成下端面2，接着再对第二折叠区域3000的第三翻折区域3200和第四翻折区域3300进行翻折，使得上端面区域3100形成上端面2，为了美观，第一翻折区域1200、第二翻折区域1300、第五翻折区域5200和第六翻折区域5300按照设置其区域内的翻折折痕500进行折叠，并向下端面2翻折，而第三翻折区域3200和第四翻折区域3300按照设置其区域内的翻折折痕500进行折叠后，向第一侧壁区域2000和第二侧壁区域4000共同形成的侧壁翻折。如果未设置第一辅助折痕400时，侧壁自然形成圆鼓形，当设置了第一辅助折痕400和第二辅助折痕410时，则由于第一辅助折痕400和第二辅助折痕410的作用，侧壁形成如钻石型侧壁，使得外观更为美观大方，也便于包装容器批量生产后外形统一。
如上所述，对本发明的实施例进行了详细地说明，但是只要实质上没有脱离本发明的发明点及效果可以有很多的变形，这对本领域的技术人员来说是显而易见的。因此，这样的变形例也全部包含在本发明的保护范围之内。
