Description

[根据细则37.2由ISA制定的发明名称]　一种具有保温及防碰撞性能的灌装袋及其制造方法 【技术领域】
本发明涉及一种灌装袋，尤其涉及一种具有较好保温及防碰撞性能的灌装袋及其制造方法。
【背景技术】
灌装袋一般用于灌装流质食品，很多流质食品在携带过程中都需要进行保温处理，不然，会因流质食品的温度上升或降低而造成变质或失去原有口感，例如，酸奶、冷饮、热咖啡、热奶茶等，但是，目前的灌装袋都没有保温性能。
为解决上述流质食品的保温问题，目前一般都是将灌装有流质食品的灌装袋放置在一个笨重的保温箱中进行携带，非常不方便。
有的技术方案是在灌装袋的内壁直接复合一层保温膜，虽有所改善，但其保温效果仍然较差。
此外，由于灌装袋一般也没有防碰撞性能，容易受到挤压或碰撞而受损，导致里面灌装的流质液体流出，造成浪费和环境污染。
【发明内容】
本发明要解决的技术问题是提供一种具有较好保温及防碰撞性能的灌装袋及其制造方法，这种灌装袋具有较好的保温效果和防碰撞性能，结构简单，成本较低。采用的技术方案如下：
一种具有较好保温及防碰撞性能的灌装袋，包括封闭式袋体和灌装管头，灌装管头设置在封闭式袋体的顶部，其特征是：所述封闭式袋体包括基材层和至少一层薄膜层，基材层的至少一侧面设有网状胶层，薄膜层通过网状胶层与基材层复合在一起，基材层、网状胶层、薄膜层之间构成多个气泡腔，气泡腔中充填有气体。
上述基材层可以采用较厚的PP、PE等塑料片材，上述薄膜层可以采用较薄 的PP、PE塑料薄膜。
由于封闭式袋体的侧面通过网状胶层复合一层薄膜层，从而形成一层密集的气泡腔，气泡腔中充填气体，从而在封闭式袋体的侧面形成气体保温夹层，从而使这种灌装袋具有较好的保温效果，该气体保温夹层同时具有较好的减震、防碰撞性能，而气体保温夹层由网状胶层、薄膜层复合而成，具有较高的平整度，结构相当简单，生产成本也较低，能够得到广泛的推广应用。
作为本发明的优选方案，所述封闭式袋体为自立袋。
作为本发明的优选方案，所述封闭式袋体的下部设有出液龙头。
作为本发明的优选方案，所述封闭式袋体的顶部设有提手。
作为本发明进一步的优选方案，所述网状胶层由多个均匀排列的封闭胶环构成，所述气泡腔中密封有发泡剂。发泡剂一般可以采用碳酸盐，碳酸盐是无机发泡剂，无机发泡剂能够释放较多的气体，并且无污染，主要是碳酸钙、碳酸镁、碳酸氢钠，其中碳酸氢钠是白色粉末，比重2.16，分解温度约为100-140℃，分解后释放CO 2气体。通过网状胶层的封闭胶环分别形成多个封闭的气泡腔，并密封发泡剂，通过加热处理，使发泡剂释放气体，从而在气泡腔中填充气体，无需在使用时进行充气，使用更加方便，而由于气泡腔是相互独立且封闭的，即使部分气泡腔破损，只是发生局部漏气，仍具有较好的保温效果和防碰撞新能。
作为本发明更进一步的优选方案，所述封闭式袋体包括底板和至少三个侧板，各个侧板的底边与底板的边缘之间通过底部定型封边形成折边，相邻两个侧板的侧边通过纵向定型封边封合在一起，各个侧板的顶边通过顶部定型封边封合在一起。底部定型封边、纵向定型封边、顶部定型封边起到连接、定型的作用，以使封闭式袋体维持固定的形状，比一般的折边具有更好的结构稳定性。
作为本发明进一步的优选方案，所述网状胶层由多个均匀排列的半封闭胶环构成，相邻两个半封闭胶环之间设有缺口，所述封闭式袋体上设有充气阀。通过将网状胶层设置为由多个均匀排列的半封闭胶环构成，网状胶层的半封闭 胶环形成多个相互连通的气泡腔，通过充气阀进行充气就在各个气泡腔中充填入气体，形成气体保温夹层，无需填充发泡剂，减少生产工序，进一步降低生产成本。
作为本发明更进一步的优选方案，所述封闭式袋体包括底板和至少三个侧板，各个侧板的底边与底板的边缘之间通过底部定型封边形成折边，相邻两个侧板的侧边通过纵向定型封边封合在一起，各个侧板的顶边通过顶部定型封边封合在一起，各条底部定型封边、纵向定型封边上均设有与所述气泡腔相通的过气孔，所述充气阀设置在底板或侧板上。底部定型封边、纵向定型封边、顶部定型封边起到连接、定型的作用，以使封闭式袋体维持固定的形状，比一般的折边具有更好的结构稳定性，而在各条底部定型封边、纵向定型封边上设置过气孔，使得各个侧板、底板上的气泡腔相互连通，均设置一个充气阀就可以完成整个封闭式袋体的充气。上述充气阀为薄膜充气封条。薄膜充气封条为一种单向充气阀，结构简单，成本低廉，属于现有技术，在这里不再详述。
上述定型封边一般可以通过热封方式形成。
一种具有较好保温及防碰撞性能的灌装袋的制造方法，其特征在于包括如下步骤：
(1)在基材层的一侧面印刷一层网状胶层，网状胶层由多个均匀排列的半封闭胶环构成，相邻两个半封闭胶环之间设有缺口；
(2)通过网状胶层在基材层上复合一层薄膜层，使基材层、网状胶层、薄膜层之间构成多个气泡腔；
(3)按照灌装袋的展开图进行裁切并在相应位置上预先冲剪出灌装孔和出液孔；
(4)通过热合的方式进行热封，形成各条底部定型封边、纵向定型封边、顶部定型封边以及封合薄膜充气封条，各条底部定型封边、纵向定型封边预留间隙以形成过气孔，薄膜充气封条与气泡腔相通；
(5)分别以热合方式封合灌装管头和出液龙头。
一种具有较好保温及防碰撞性能的灌装袋的制造方法，其特征在于包括如下步骤：
(1)在基材层的一侧面印刷一层网状胶层，网状胶层由多个均匀排列的封闭胶环构成；
(2)在网状胶层的各个封闭胶环中填充适量的发泡剂；
(3)通过网状胶层在基材层上复合一层薄膜层，使基材层、网状胶层、薄膜层之间构成多个气泡腔，各个气泡腔均将相应的发泡剂密封；
(4)进行加热处理，使发泡剂释放气体填充各个气泡腔；
(5)按照灌装袋的展开图进行裁切并在相应位置上预先冲剪出灌装孔和出液孔；
(6)通过热合的方式进行热封，形成各条底部定型封边、纵向定型封边、顶部定型封边；

实施例一
如图1、图2所示，这种具有较好保温及防碰撞性能的灌装袋，包括封闭式袋体1和灌装管头2，灌装管头2设置在封闭式袋体1的顶部，封闭式袋体1为自立袋，封闭式袋体1的下部设有出液龙头3，封闭式袋体1的顶部设有提手4；封闭式袋体的侧壁1包括基材层5和薄膜层6，基材层5的侧面设有网状胶层7，薄膜层6通过网状胶层7与基材层5复合在一起，基材层5、网状胶层7、薄膜层6之间构成多个气泡腔8，气泡腔8中充填有气体。
上述网状胶层7由多个均匀排列的半封闭胶环701构成，相邻两个半封闭胶环701之间设有缺口702，封闭式袋体1上设有薄膜充气封条9。
上述封闭式袋体1包括底板101和四个侧板102，各个侧板102的底边与底板101的边缘之间通过底部定型封边103形成折边，相邻两个侧板102的侧边通过纵向定型封边104封合在一起，各个侧板102的顶边通过顶部定型封边105封合在一起，各条底部定型封边103、纵向定型封边104上均设有与气泡腔8相通的过气孔106，上述薄膜充气封条9设置在底板101或侧板102上。
上述灌装管头2可以设置在顶部定型封边105上，也可以设置在其中一个侧板102的上部。
上述基材层5可以采用较厚的PP、PE等塑料片材，上述薄膜层6可以采用较薄的PP、PE塑料薄膜。
由于封闭式袋体1的侧面通过网状胶层7复合一层薄膜层6，从而形成一层密集的气泡腔8，通过薄膜充气封条9进行充气，气体经过各个过气孔106、缺口702进入到各个气泡腔8中，从而在封闭式袋体1的侧面形成气体保温夹层10，从而使这种灌装袋具有较好的保温效果，该气体保温夹层10同时具有较好的减震、防碰撞性能，而气体保温夹层10由网状胶层7、薄膜层6复合而成，具有较高的平整度，结构相当简单，生产成本也较低，能够得到广泛的推广应用。
如图3所示，在一种具体方案中，基材层5的两侧面均通过网状胶层7复合一层薄膜6，从而在封闭式袋体1的内外两侧面均形成气体保温夹层10。
参考图1、图2，这种具有较好保温及防碰撞性能的灌装袋的制造方法，包括如下步骤：
(1)在基材层5的一侧面印刷一层网状胶层7，网状胶层7由多个均匀排列的半封闭胶环701构成，相邻两个半封闭胶环701之间设有缺口702；
(2)通过网状胶7在基材层5上复合一层薄膜层6，使基材层5、网状胶层7、薄膜层6之间构成多个气泡腔8；
(3)按照灌装袋的展开图进行裁切并在相应位置上预先冲剪出灌装孔和出液孔；
(4)通过热合的方式进行热封，形成各条底部定型封边103、纵向定型封边104、顶部定型封边105以及封合薄膜充气封条9，各条底部定型封边103、纵向定型封边104预留间隙以形成过气孔106，薄膜充气封条9与气泡腔8相通；
(5)分别以热合方式封合灌装管头2和出液龙头3。
实施例二
如图4、图5所示，在其它部分均与实施例一相同的情况下，其区别仅在于：封闭式袋体1包括底板111、顶板112和两个侧板113，两个侧板113的侧边通过纵向定型封边114封合在一起而构成筒状，两个侧板113的底边与底板111的边缘之间通过底部定型封边115形成折边，各个侧板113的顶边与顶板112的边缘通过顶部定型封边116封合在一起；网状胶层7由多个均匀排列的封闭胶环711构成，气泡腔8中密封有发泡剂。通过网状胶层7的封闭胶环711分别形成多个封闭的气泡腔8，并密封发泡剂，通过加热处理，使发泡剂释放气体，从而在气泡腔8中填充气体，无需在使用时进行充气，使用更加方便，而由于气泡腔8是相互独立且封闭的，即使部分气泡腔8破损，只是发生局部漏气，仍具有较好的保温效果。
这种具有较好保温及防碰撞性能的灌装袋的制造方法，包括如下步骤：
(1)在基材层5的一侧面印刷一层网状胶层7，网状胶层7由多个均匀排列的封闭胶环711构成；
(2)在网状胶层7的各个封闭胶环711中填充适量的发泡剂；
(3)通过网状胶层7在基材层5上复合一层薄膜层6，使基材层5、网状胶层7、薄膜层6之间构成多个气泡腔8，各个气泡腔8均将相应的发泡剂密封；
(4)进行加热处理，使发泡剂释放气体填充各个气泡腔8；
(5)按照灌装袋的展开图进行裁切并在相应位置上预先冲剪出灌装孔和出液孔；
(6)通过热合的方式进行热封，形成各条底部定型封边114、纵向定型封边115、顶部定型封边116；
(7)分别以热合方式封合灌装管头2和出液龙头3。
此外，需要说明的是，本说明书中所描述的具体实施例，其各部分名称等可以不同，凡依本发明专利构思所述的构造、特征及原理所做的等效或简单变化，均包括于本发明专利的保护范围内。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，只要不偏离本发明的结构或者超越本权利要求书所定义的范围，均应属于本发明的保护范围。
