Description

一种具有防侧漏的卫生用品用吸收体
技术领域
本发明涉及一种卫生用品，特别是一种具有防侧漏的卫生用品用吸收体。
背景技术
卫生巾是女性在月经期间用来吸收来自阴道流出的经血的常用生活用品，现有的卫生巾吸收体的面层一般为平面结构，经血从面层渗透到吸收芯体，在吸收体面层上一般会设置有用于防止液体侧漏的压缩导流槽，负责将中部溢出的经血导流至吸收体的两端位置，加快经血吸收，但现有卫生巾防侧漏结构简单，一般仅有一道防侧漏结构，若女性经血排出速度较快且容量大时，经血的排出速度快于吸收体的吸收速度，经血则会从侧边位置溢出，导致防侧漏效果不佳。
发明内容
为了克服现有技术的不足，本发明提供一种具有防侧漏的卫生用品用吸收体。
本发明解决其技术问题所采用的技术方案是：
一种具有防侧漏的卫生用品用吸收体，所述吸收体具有长度方向、宽度方向以及厚度方向，在所述厚度方向由上往下依次设有透液层、吸收芯和防漏层，所述吸收芯的中部沿所述长度方向一体成型有吸收凸条，所述吸收芯的两侧边缘对应所述吸收凸条的两侧沿所述长度方向一体成型有防漏凸条，所述吸收凸条与所述防漏凸条之间形成有容质凹槽。
所述防漏凸条在所述厚度方向上的投影为中部内凹、两端外凸的弧形状。
所述防漏凸条在所述长度方向上的长度不小于所述吸收凸条的长度，且所述吸收凸条在所述长度方向上的长度占所述吸收体总长的30％-50％。
所述吸收凸条在所述厚度方向上的高度不低于所述防漏凸条的高度。
所述吸收芯在所述厚度方向上的顶面高度不低于所述容质凹槽的底面高度。
所述吸收凸条的侧面环绕设置有内凹的第一吸收弧面，所述防漏凸条的侧面环绕设置有内凹的第二吸收弧面。
所述第一吸收弧面与所述吸收凸条的顶面之间设有第一圆弧倒角，所述第二吸收弧面与所述防漏凸条的顶面之间设有第二圆弧倒角。
所述吸收芯由木浆和高吸水树脂组成。
本发明的有益效果是：本发明在吸收芯的中部一体成型有吸收凸条，对应吸收凸条的两侧设有防漏凸条，使吸收凸条与防漏凸条之间形成容质凹槽，使用时，吸收凸条服帖在女性阴道口处，防漏凸条则服帖在阴道口的两侧，当经血排出速度较快且容量大时，从吸收凸条处溢出的经血会集中在容质凹槽内，并驱使经血向容质凹槽的两端导流，相比于现有的压缩导流槽，在具备导流功能，加快吸收速度的同时，还可作为暂时容纳经血的空间，能有效防止经血从吸收体两侧溢出，具有良好的防侧漏效果。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图2是本发明的俯视图；
图3是本发明的剖面示意图。
具体实施方式
参照图1至图3，一种具有防侧漏的卫生用品用吸收体，所述吸收体具有长度方向、宽度方向以及厚度方向，在所述厚度方向由上往下依次设有透液层1、吸收芯2和防漏层3，所述透液层1可采用具有透液性的导流无纺布制成，所述吸收芯2由木浆和高吸水树脂(SAP材料)组成，所述防漏层3为不透液性的PE底膜，所述吸收芯2的中部沿所述长度方向一体成型有吸收凸条4，所述吸收芯2的两侧边缘对应所述吸收凸条4的两侧沿所述长度方向一体成型有防漏凸条5，在本实施例中，所述吸收凸条和防漏凸条可在吸收芯2生产时采用压缩成型，所述吸收凸条4与所述防漏凸条5之间形成有容质凹槽6，使用时，将吸收体服帖至女性的鼠蹊部(腹股沟)处，吸收凸条服帖在女性阴道口处，防漏凸条则服帖在阴道口的两侧，当经血排出速度较快且容量大时，从吸收凸条处溢出的经血会集中容纳在容质凹槽内，防漏凸条可阻挡经血向两侧溢出，并驱使经血向容质凹槽的两端导流，使吸收芯加快吸收，相比于现有的压缩导流槽，在具备导流功能，加快吸收速度的同时，还可作为暂时容纳经血的空间，能有效防止经血从吸收体两侧溢出，具有良好的防侧漏效果。
所述防漏凸条5在所述厚度方向上的投影为中部内凹、两端外凸的弧形状，在本实施例中，所述防漏凸条5的弧度半径在95mm-100mm之间，弧度在0.43-0.52rad之间，使得所述防漏凸条5与女性鼠蹊部的两侧相契合，可更好的服帖，有效减少摩擦，提高女性使用时的舒适度。
所述防漏凸条5在所述长度方向上的长度不小于所述吸收凸条4的长度，且所述吸收凸条4在所述长度方向上的长度占所述吸收体总长的30％-50％，可与不同规格不同吸收容量的吸收体相适应，适用于不同需求的消费人群，在本实施例中，所述吸收体的在所述长度方向上的长度范围在360-420mm之间，女性用户在使用吸收体时，需要吸收体的表面与女性用户的鼠蹊部贴合，所以吸收体会在所述长度方向上形成与女性用户的鼠蹊部相契合的弧形状，由于防漏凸条5需要起到防侧漏的作用，而吸收凸条4仅用于与女性阴道口贴合，防漏凸条5的长度大于所述吸收凸条4的长度，相当于增加防漏凸条5与鼠蹊部的贴合长度，有利于增加防侧漏的保护范围，同时也增加了容质凹槽6的外侧长度，从而增加容质凹槽6的导流长度，进一步提高吸收体的吸收速度。
所述吸收凸条4在所述厚度方向上的高度不低于所述防漏凸条5的高度，在本实施例中，所述吸收凸条4的高度范围为8-12mm，所述防漏凸条5的高度范围为6-10mm，女性用户在使用吸收体时，需要吸收体的表面与女性用户的鼠蹊部贴合，吸收体不仅在所述长度方向上形成与女性用户的鼠蹊部相契合的弧形状，在所述宽度方向上同样会形成与女性用户的鼠蹊部相契合的弧形状，具体形状为吸收体在所述厚度方向上对应所述吸收凸条4的位置下凹，对应所述防漏凸条5的两侧上凸，女性用户在正常使用吸收体时，所述防漏凸条5位于鼠蹊部的两侧，由于比较靠近女性内裤或经期裤裤脚橡筋的位置，所以位于两侧的防漏凸条5相比于位于裆部的吸收凸条4会承受更大的压力，导致产生更大的形变，防漏凸条5过厚会使得女性用户的鼠蹊部两侧承受压力过大，增加防漏凸条5与鼠蹊部两侧之间的摩擦，导致女性用户使用时的舒适度大大降低，所以在不影响防漏凸条5与鼠蹊部两侧服帖的情况下，吸收凸条4的高度因不低于所述防漏凸条5的高度。
所述吸收芯2在所述厚度方向上的顶面高度不低于所述容质凹槽6的底面高度，有利于增大容质凹槽的内部空间，从而增大容纳经血的容量。
所述吸收凸条4的侧面环绕设置有内凹的第一吸收弧面41，所述防漏凸条5的侧面环绕设置有内凹的第二吸收弧面51，在本实施例中，所述第一吸收弧面41、第二吸收弧面51的弧度半径在6-8mm之间，弧度在1.3-1.5rad之间，所述吸收凸条和防漏凸条均采用弧形侧面，即容置凹槽的两侧均为弧形侧面，有利于增大容置凹槽对经血的吸收面积，从而提高吸收型的吸收速度。
所述第一吸收弧面41与所述吸收凸条4的顶面之间设有第一圆弧倒角8，所述第二吸收弧面51与所述防漏凸条5的顶面之间设有第二圆弧倒角9，可有效减少吸收凸条4、防漏凸条5与女性用户接触面之间的摩擦，提高使用舒适度。
在本实施例中，所述吸收体的两侧还包覆有两侧无纺布7，所述吸收体的底部依次设有弹性无纺布10和外层无纺布11，所述两侧无纺布7的上端还设有向外翻折的翻折部12，所述翻折部12在所述长度方向上并设有弹性橡筋13，从而提高吸收体整体的弹性挺度，避免吸收体产生形变过大且不能复原。
以上的实施方式不能限定本发明创造的保护范围，专业技术领域的人员在不脱离本发明创造整体构思的情况下，所做的均等修饰与变化，均仍属于本发明创造涵盖的范围之内。
