Description

纸尿裤
技术领域
本发明涉及一种纸尿裤。
背景技术
目前市面上的纸尿裤多是在腰部及腿部围裆处设置橡皮筋丝，使腰部及腿部的束缚更为贴合。目前市面上还没有在裆部设置橡皮筋丝或片状弹性体的纸尿裤，在纸尿裤吸收尿液后会变重下垂，卡在两大腿之间，久而久之，会使腿形趋向O型腿发展，而且尿液的重量还会对腿部的受力点产生很大的下坠力，不仅影响舒穿着的舒适性，还容易引起尿液侧漏。
而且，目前纸尿裤设在前腰部的魔术贴毛片通常设置较长，呈左右连通的结构，且魔术贴毛片的外边缘还分别连接一无纺布片，通常魔术贴毛片离两侧边缘距离在6cm以上，由于使用时，处于左右中间部位的魔术贴毛片其实是用不到的，还有魔术贴毛片外边缘的两无纺布片也用不到，因此较为浪费，且业内为了降低成本，往往会减小魔术贴毛片的宽度，如通常为2-4cm，如此又会影响粘贴的效果，使粘贴不够牢靠。
再者，纸尿裤的吸水性和导流的效率是标志纸尿裤好坏的重要指标，因此为提高纸尿裤的吸水性和导流效率，业内已经有了很多解决方案，但还没有出现在其吸收芯体上开槽的方式来提高纸尿裤的吸水性和导流效率。
另外，传统的纸尿裤一般的立体护围都是平面结构，这样在胶固化后会形成硬边，当橡筋收缩时，硬边形成众多的硬尖角，很容易勒伤人体皮肤，特别是婴儿稚嫩的皮肤。
发明内容
本发明要解决的技术问题，在于提供一种纸尿裤，对现有技术中的纸尿裤结构加以改进，有效地提升了纸尿裤的性能和穿戴的舒适度，还高效利用和节能省料。
本发明是这样实现的：一种纸尿裤，包括裆部以及连接于裆部两端的前腰部和后腰部，所述裆部、前腰部和后腰部的内部则设有吸收芯体，所述裆部的边缘设有立体护围，所述前腰部的防水底层上粘贴有魔术贴毛片，其特征在于：所述裆部的防水底层设置有复数条纵向布置的橡皮筋丝或片状弹性体；所述吸收芯体沿长度方向开设有至少一断口槽；所述立体护围包括护围片主体和隔离护带，所述护围片主体的外边缘与隔离护带的中部连接，从而使所述隔离护带与所述护围片主体构成T型结构；所述魔术贴毛片为两段式结构，由左毛片段和右毛片段组成，所述左毛片段设于前腰部的左侧，右毛片段设于前腰部的右侧，且所述左毛片段和右毛片段的外边缘不设无纺布片。
进一步的，所述橡皮筋丝或片状弹性体的两端衔接至所述前腰部和后腰部的下端。
进一步的，所述断口槽的断面高度大于等于吸收芯体的高度的一半。
进一步的，所述断口槽为U形槽或V形槽；所述U形槽的宽度为5-25mm；所述V形槽的槽口宽度为5-25mm。
进一步的，所述断口槽的长度为8-30cm，且断口槽的两端部离所述吸收芯体的长方向边缘有一段3cm以上的距离。
进一步的，所述隔离护带的宽度为0.8-2cm，且设置有3-6道橡皮筋丝，而护围片主体上不设橡皮筋丝。
进一步的，所述左毛片段和右毛片段的宽度相等并处于6-20cm之间，且左右毛片段的间距3cm以上，且左右毛片段与侧边边缘的距离为2-5cm。
本发明具有如下优点：
1、通过在纸尿裤的裆部的防水底层内设置复数条纵向布置的橡皮筋丝或片状弹性体，以对裆部产生一向上的托举力，防止纸尿裤吸收尿液变重下坠而产生O型腿以及尿液侧漏。
2、通过在纸尿裤的吸收芯体沿长度方向开设有至少一断口槽，由于断口处渗透效果更佳，以增强纸尿裤的吸水性和导流效率，可以让纸尿裤充分利用，还可有效防止侧漏，且断口槽的设置还可让纸尿裤穿着时吸收芯体根据大腿间隙自然折起，有效防止O形腿。
3、通过在纸尿裤的立体护围的护围片主体上加设隔离护带，且护围片主体的外边缘与隔离护带的中部连接，从而使所述隔离护带与所述护围片主体构成T型结构，使立体护围的边缘不会产生硬尖角，完全避免了皮肤被刺伤及磨伤的现象，且防侧漏性也可显著提高。
4、将纸尿裤的魔术贴毛片设置为两段式结构，其左毛片段设于前腰部的左侧并靠近边缘，右毛片段设于前腰部的右侧并靠近边缘，且所述左毛片段和右毛片段的外边缘不设无纺布片，这样就可以保证腰围的情况下减少无纺布用料及魔术贴毛片用料，既可以降低成本，又可以保证前腰部与后腰部粘贴的可靠性。

具体实施方式
如图1至图4a所示，本发明的纸尿裤，包括裆部1以及连接于裆部1两端的前腰部2和后腰部3，所述裆部1、前腰部2和后腰部3的内部则设有吸收芯体41，所述裆部1的边缘设有立体护围5，所述前腰部2的防水底层42(即最外层)上粘贴有魔术贴毛片6。
如图2a所示，所述裆部1的防水底层42设置有复数条纵向布置的橡皮筋丝7，或者如图2b所示，在裆部1的防水底层42设置有复数条纵向布置的片状弹性体8；以对裆部1产生一向上的托举力，防止纸尿裤吸收尿液变重下坠而产生O型腿以及尿液侧漏。所述橡皮筋丝7或片状弹性体8的两端衔接至所述前腰部2和后腰部3的下端，如此可使裆部1的纵向收缩效果更佳，还能通过腰部力量来更好地支撑裆部1。
如图3至图3b所示，所述吸收芯体41沿长度方向开设有至少一断口槽412；如图3a和图3b所示，所述断口槽412的断面高度h大于等于吸收芯体41的高度H的一半并小于等于吸收芯体41的高度H，断口槽412的断面的高度h越大，断面的吸收能力越好，但显然不能超过吸收芯体41的高度。且断口槽2的宽度W不宜太宽，如图3a所示，若所述断口槽412为U形槽，则该断口槽的宽度为5-25mm为佳。或者是如图3b所示，所述断口槽412为V形槽，且该断口槽412的槽口宽度为5-25mm为佳。太宽容易影响吸收芯体41的整体吸收量。所述断口槽412的两端部离所述吸收芯体41的长方向边缘有一段距离D，该距离D大于等于3cm为佳，以防止尿液的量太大时从吸收芯体41的端部侧漏，且所述断口槽412的长度为8-30cm为佳，以实现良好的导流和扩散效果。
如图4和图4a所示，所述立体护围5包括护围片主体51和隔离护带52，所述护围片主体51的外边缘与隔离护带52的中部连接，从而使所述隔离护带52与所述护围片主体51构成T型结构；所述隔离护带52的宽度为0.8-2cm，且设置有3-6道橡皮筋丝53，而护围片主体51上不设橡皮筋丝。通过在围片主体51的外边缘设置隔离护带52，使用时，围片主体51的外边缘不会直接接触皮肤，而是通过隔离护带52的平面来接触皮肤，这样就完全避免了皮肤被刺伤及磨伤的现象，且防侧漏性也可显著提高。
再如图1所示，所述魔术贴毛片6为两段式结构，由左毛片段61和右毛片段62组成，所述左毛片段61设于前腰部2的左侧，右毛片段62设于前腰部2的右侧，且所述左毛片段和右毛片段的外边缘不设无纺布片。所述左毛片段61和右毛片段62的宽度相等并处于6-20cm之间，且左右毛片段的间距3cm以上，且左右毛片段与侧边边缘的距离为2-5cm。将纸尿裤的魔术贴毛片6设置为两段式结构，其左毛片段设于前腰部的左侧并靠近边缘，右毛片段设于前腰部的右侧并靠近边缘，这样就可以保证腰围的情况下减少无纺布用料及魔术贴毛片用料，既可以降低成本，又可以保证前腰部2与后腰部3粘贴的可靠性。
虽然以上描述了本发明的具体实施方式，但是熟悉本技术领域的技术人员应当理解，我们所描述的具体的实施例只是说明性的，而不是用于对本发明的范围的限定，熟悉本领域的技术人员在依照本发明的精神所作的等效的修饰以及变化，都应当涵盖在本发明的权利要求所保护的范围内。
