Description

一种新型环保纸质袋体 技术领域
本发明涉及快递，邮政物流的包装，具体地说，涉及一种新型环保纸质袋体。
背景技术
在包装，邮政快递领域，纸质包装袋应用广泛，纸质包装袋具有成本低，可回收的优点。目前市场上用的纸质包装袋在部分具有缓冲保护层，起到保护容纳在内部的物品的目的。常见的缓冲保护层包括纸屑填充物，塑料泡膜，充气泡等，但是这些填充物或多或少都会对环境造成污染，例如纸屑填充物会在制作时造成空气粉尘污染，而塑料泡膜或者充气泡在使用后，塑料不容易分离再回收，丢弃后不容易降解。
发明内容
本发明的目的在于提供一种新型环保纸质袋体，旨在解决现有的包装袋对环境造成污染的技术问题。
本发明提供一种新型环保纸质袋体。该袋体用于快递、邮政、包装的快递，其由平面结构组成，所述平面结构包括纸质第一面以及附着于所述第一面上，用于起到缓冲保护作用的内芯层，所述内芯层包括至少一层衬垫，所述衬垫为经模压后具有多个凹凸不平的排列形状的纸材。
在本实施方式中，内芯层通过凹凸不平排列的形状使衬垫厚度增加，并在厚度范围内具有一定的弹性，凸出的部分承受压力，起到缓冲的作用，从而达到保护物品的目的。其中该衬垫也是纸质材料，可以回收再利用，不会对环境造成污染；同时，该衬垫是通过模压的方式生产，模压技术成熟，成本低，有利于大规模生产。

具体实施方式
下面结合具体实施例和说明书附图对本发明做进一步阐述和说明:
请参考图1至图2，本发明公开一新型环保纸质袋体，用于快递、邮政、包装的快递，该袋体可以是以常见的快递袋，信封等方式存在。具体的，所述袋体由平面结构10组成，所述平面结构10包括纸质第一面11以及附着于所述第一面11上，用于起到缓冲保护作用的内芯层12，所述内芯层12包括至少一层衬垫120，所述衬垫120为经模压后具有多个凹凸不平的排列形状的纸材。
在本实施方式中，内芯层12通过凹凸不平排列的形状使衬垫120厚度增加，并在厚度范围内具有一定的弹性，凸出的部分承受压力，起到缓冲的作用，从而达到保护物品的目的。其中该衬垫120也是纸质材料，可以回收再利用，不会对环境造成污染；同时，该衬垫120是通过模压的方式生产，模压技术成熟，成本低，有利于大规模生产。
参考图3，所述平面结构10还包括第二面13，所述内芯层12夹持于所述第一面11与所述第二面13之间。如图4，图4是图3的平面结构10折叠形成的新型环保纸质袋体，此时新型环保纸质袋体相交于图2中增加一层第二面13。
在本实施方式中，通过增加第二面13可以更好的将内芯层12固定，且同时提高了新型环保纸质袋体的受力强度，保护作用进一步增强。
其中，所述平面结构10折叠封边，或两所述平面结构10层叠封边形成所述袋体。
也就是说袋体的制作至少包括两种方式，方式一：将平面结构10沿一条 中心线折叠，之后在垂直于折叠线的两侧的边缘涂胶封边，形成袋体；方式二：将两片平面结构10层叠起来，然后将平面结构10边缘的3侧边封边，形成袋体。另外，袋体的形成还可能包括其他实施方式，只要是通过本发明记载的平面结构10形成，均是本申请的保护范围。
参考图1，图5，所述衬垫120包括凸部121，所述凸部121包括凸起的多根肋条122，相对于所述肋条122，在所述肋条122边缘外侧形成凹部123，所述凸部121与所述凹部123间插设置。
在本实施方式中，模压后形成的肋条122与肋条122边缘形成的凹部123间插设置，能够使多条肋条122同时承受压力，对于袋体来说，受理均匀，多条肋条122同时发生缓冲形变，进一步能够提高缓冲能力。
参考图5及图6，所述肋条122向所述边缘外侧的凹部123设置有圆倒角1220，使得所述凸部121向所述凹部123平滑过度。
在本实施方式中，圆倒角1220一方面能够是凸部121与凹部123连接更加平滑，从而在凸部121受力发生形变时，获得更好的支撑，提高缓冲效果；另一方面，在模压后形成肋条122时，可以防止凸部121与凹部123过陡变化，造成模具压下时纸材的破损，提高衬垫120的良率。
在本发明中，肋条122的设置具有多种方式，这里仅针对较为简单，比较具有代表性的方式做陈述，其中应该认为肋条122的数量以及肋条122的位置只要能够符合上述陈述内容均应该是本专利保护的内容。
具体的，参考图1，所述肋条122至少包括第一肋条1221和第二肋条1222，在这里所述第一肋条1221与第二肋条1222至少有一条，当然也可以是多条，多条肋条122的设置平铺在整个纸材上，其中，所述第一肋条1221与所述第二肋条1222彼此相交，相对所述第一肋条1221及所述第二肋条1222的边缘外侧形成所述凹部123。所述第一肋条1221与所述第二肋条1222彼此垂直，所述第一肋条1221与所述第二肋条1222合围形成四边形区域，所述四边形区域为所述凹部123。
在本发明的另一种实施方式中，参考图7，所述肋条122还包括第三肋条1223，所述第一肋条1221、第二肋条1222与所述第三肋条1223彼此相交并合 围，从而形成三角形区域，所述三角形区域为所述凹部123。
在本发明的其他实施方式中，如图8，所述肋条还包括第四肋条1224，多条所述第一肋条1221、第二肋条1222与所述第四肋条1224各自平行设置，两条所述第一肋条1221、所述第二肋条1222与所述第四肋条1224彼此相交并合围，从而形成八边形区域，所述八边形区域为所述凹部。该肋条122也可以是更多条，如8条，多条肋条122形成八边形，通过多条肋条122模压后，形成特定的凸部121，同样能够实现缓冲保护的作用。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
