Abstract

本发明涉及一种纸尿裤，特别是一种防漏性能良好的纸尿裤。本发明包括亲水面层、防水底层，在亲水面层与防水底层之间是吸水棉芯层，在吸水棉芯层纵向两端外侧，亲水面层与防水底层粘合在一起，在纸尿裤两侧各设有一防止侧漏的立体护围，立体护围内装有可纵向收缩的的橡筋，立体护围是直接粘贴在防水底层上。上述结构中，立体护围纵向两端与亲水面层粘合，粘合位置处于吸水棉芯层纵向两端的外侧，最好是立体护围内橡筋的收缩长度大于吸水棉芯层的纵向长度。还可在在吸水棉芯层的纵向端加装一片吸水层，并可在正面或背面加装弹性腰围。具有以上结构的本发明既可以防止尿液向两侧渗漏，又可以防止尿液向前后渗漏，是一种理想的防漏尿裤。

Description

一种全面防漏的纸尿裤
技术领域
本发明涉及一种纸尿裤，特别是一种防漏性能良好的纸尿裤。
背景技术
传统的纸尿裤，其结构大致是：上面为一亲水面层，下面为一防水底层（即纸尿裤的背面），中间为吸水棉芯层。经一体裁剪压合成型，在纸尿裤两侧边各设有一立体护围，以防排泄物量大时从侧边漏出，立体护围内装有可纵向收缩的的橡筋。另外在裤体的后端两侧设有一对魔术贴，以便将裤体的前后端粘连起来穿戴在人体上。传统纸尿裤的立体护围立面的基部是先粘贴在亲水面层上，然后再与防水底层粘合，尿液有时会沿亲水面层的纤维往两侧渗漏；而且，传统纸尿裤的立体护围主要是防止侧漏的，但有时排泄物会从纸尿裤的纵向两端（即前后端）渗漏，而造成衣物的污染；并且，传统纸尿裤的弹性腰围都是装配在纸尿裤的的亲水面层和防水底层之间，或者粘贴在亲水面层上，弹性腰围的横向宽度都不是很宽，拉伸时的伸展性有限，不能做到非常贴身。
发明内容
本发明需解决的技术问题是：针对传统纸尿裤在防漏方面的不足，而提供一种能综合解决侧漏及前后漏问题的纸尿裤。
本发明所采用的技术方案：本发明包括亲水面层、防水底层，在亲水面层与防水底层之间是吸水棉芯层，在吸水棉芯层纵向两端外侧，亲水面层与防水底层粘合在一起，在纸尿裤两侧各设有一防止侧漏的立体护围，立体护围内装有可纵向收缩的的橡筋，立体护围立面的基部是直接粘贴在防水底层上。
上述结构中，立体护围纵向两端与亲水面层粘合，粘合位置处于吸水棉芯层纵向两端的外侧，最好是立体护围内橡筋的收缩长度大于吸水棉芯层的纵向长度。
还可在在吸水棉芯层的纵向端加装一片吸水层，该片吸水层直接粘贴于两侧边立体护围及亲水面层上面。
本发明还可在纸尿裤的纵向端装配弹性腰围，如果弹性腰围装在正面，就将弹性腰围覆盖在两侧立体护围之上，其纵向端有一部分覆盖叠合在吸水棉芯层的纵向端的上面。
为提高伸展性，本发明也可将弹性腰围装配在防水底层的背面。
本发明的有益效果：具有以上结构的本发明既可以防止尿液向两侧渗漏，又可以防止尿液向前后渗漏，是一种理想的防漏尿裤。
附图说明

图2为本发明的立体护围粘贴在防水底层上的示意图；
图3为本发明立体护围粘合位置处于吸水棉芯层纵向两端外侧的示意图；
图4为本发明吸水棉芯层的纵向端加装有吸水层的示意图；
图5为本发明的弹性腰围装配在正面时的示意图；
图6为本发明的弹性腰围装配在背面时的示意图。
具体实施方式
参见图1，此为传统纸尿裤的示意图，也是图3中沿A-A向的的剖视图。其结构为：上面一层为亲水面层1，下面为一防水底层6（即纸尿裤的背面），中间为吸水棉芯层2。在纸尿裤两侧各设有一防止侧漏的立体护围3。传统纸尿裤的立体护围3立面的基部是粘合在亲水面层1上（参见图中的粘合位置10）。尿液有时会沿亲水面层1的纤维往两侧渗漏。参见图2，本发明将立体护围3立面的基部直接粘贴在防水底层6上，这样尿液接触到的都是拒水的无纺布以及防水底层，没有机会通过亲水面层的纤维往两侧渗漏，并可将立体护围做成双层结构的，效果更佳。参见图3，本发明的立体护围3的纵向两端与亲水面层1粘合，粘合位置处于吸水棉芯层纵向两端的外侧，即图3中阴影部分B表示的区域。并将立体护围3内橡筋5的收缩长度（即图3中的L2）设计成大于吸水棉芯层的纵向长度，让橡筋5拉伸时可以直接提起防水底层6，这样的结构，可使纸尿裤穿着时纵向端两头形成一定高度，有利于纵向端的防漏。参见图4，本发明还可在吸水棉芯层2的纵向两端加装吸水层4，吸水层4直接粘贴于两侧边立体护围3及亲水面层1上面。参见图5，本发明还可在纸尿裤的纵向端装配有弹性腰围7，弹性腰围7可装配在纸尿裤的正面，即覆盖在两侧立体护围之上，弹性腰围7的纵向端有一部分覆盖叠合在吸水棉芯层的纵向端的上面，可覆盖叠合在吸水棉芯层2的纵向端上面5—10mm。传统纸尿裤的弹性腰围与吸水棉芯层没有覆盖叠合的关系。采用覆盖叠合的方式，与下述U型的粘合区域配合，可以形成向内收缩提起的防水底层挡水护围，从而产生防止尿液前后漏的效果。弹性腰围与亲水面层通过热粘合或施胶的方式粘合，粘合区域呈U型，为弹性腰围纵向两端的外侧（可距离吸水棉芯层纵向两端外侧5-15mm）及弹性腰围横向两端（图中阴影部分A表示的是弹性腰围7与亲水面层1粘合的区域）。这样的结构有利于让吸水棉芯层的纵向两头至粘合区域之间向内形成环抱状，防漏效果更好。参见图6，本发明还可将弹性腰围7装配在防水底层6的背面，这样的设计可以不受胶带安装的约束，将弹性腰围7的横向宽度做得足够宽，所以伸展性良好，穿着时很贴身舒适。
