Description

一种符合人体工学的一次性卫生巾
技术领域
本发明涉及一次性吸收用品领域,尤其涉及一种符合人体工学的一次性卫生巾。
背景技术
目前,一次性卫生巾穿戴时的贴合问题是重要的研究开发方向之一。市面上普通的一次性卫生巾由于多层材料复合产生的刚性较强,穿戴时无法贴合女性身体,特别是卫生巾前后端无法弯曲,卫生巾与身体脱离,有较大的经血外漏的风险。中国专利号:CN201480027877.8公开一次性吸收衣物的弹性吸收组件。该弹性组件包括吸收芯部,所述吸收芯部包括:基底层,其具有一对侧边缘和从所述侧边缘向内隔开的纵向中心线;由所述基底层支承的弹性构造体,所述弹性构造体包括:多个隔开的弹性元件,其形成多个槽道和多个单元;和超吸收聚合物颗粒,其联接到所述弹性元件。其目的是利用弹性元件来实现弹性收缩目的,但是并无法适用于卫生巾上的穿戴贴合目的。
发明内容
因此,针对上述的问题,本发明提出一种符合人体工学的一次性卫生巾,其解决了现有卫生巾在穿戴时无法贴合身体,而造成的经血外漏风险的技术问题。
为实现上述目的,本发明采用了以下技术方案:一种符合人体工学的一次性卫生巾,包括本体,所述本体包括透液性表层、不透液性底层、设于透液性表层和不透液性底层之间的吸收芯,所述本体包括前端部、中部、后端部,所述吸收芯内位于中部处设有一主吸收部,所述主吸收部的吸收性能大于吸收芯除主吸收部外的吸收性能,本体上位于主吸收部的侧沿上通过压纹的形式形成导流槽,所述导流槽通过压制透液性表层陷入吸收芯而形成,所述吸收芯位于前端部上设有复数个沿宽度方向设置的前低洼凹槽,所述吸收芯位于后端部上设有复数个沿宽度方向设置的后低洼凹槽,所述前低洼凹槽处的吸收率为吸收芯除主吸收部外区域的吸收率的0%~75%,所述后低洼凹槽处的吸收率为吸收芯除主吸收部外区域的吸收率的0%~75%,当本体弯曲时,所述本体的前端部沿前低洼凹槽处形成前弯折部,所述本体的后端部沿后低洼凹槽处形成后弯折部,所述本体上位于各后低洼凹槽的侧边上向外设有折痕线,所述折痕线通过压制的形式形成,所述折痕线由后低洼凹槽向吸收芯周沿延伸但不穿透,所述折痕线的深度由后低洼凹槽向吸收芯周沿逐渐变小,所述折痕线的最深深度小于后低洼凹槽的深度,所述折痕线由内向外且由后端部向前端部倾斜,所述吸收芯上设有用于覆盖后低洼凹槽的弹性体,所述弹性体在本体长度方向上的拉伸比为1.1-1.2倍,所述弹性体为弹性无纺布,采用SBS嵌段共聚物型或聚烯烃型或聚氨酯制成,所述弹性体的拉伸比由靠近本体中心一侧向远离本体中心一侧呈增大趋势,所述弹性体上设有复数个穿透孔,数个穿透孔形成三至五个竖排,各竖排沿本体的宽度方向间隔设置,位于同一竖排内的相邻两穿透孔之间的间距由靠近本体中部的一侧向另一侧逐渐增大,各竖排上的穿透孔为沿横向的长条孔。
进一步的,所述本体上位于后低洼凹槽的左侧、右侧、后侧分别通过压纹的形式设有后导流槽。
进一步的,所述本体上位于后低洼凹槽上分别通过压纹的形式设有后压纹槽。
进一步的,所述吸收芯上沿中心线处设有用于连接相邻两后低洼凹槽的后连接凹槽。
进一步的,所述本体上位于后连接凹槽处通过压纹的形式设有后连接压纹槽。
进一步的,所述后导流槽、后压纹槽、后连接压纹槽均为间断线状,所述后导流槽、后压纹槽、后连接压纹槽各自不相交。
进一步的,所述本体上位于前低洼凹槽的前侧、左侧、右侧分别通过压纹的形式设有前导流槽,所述本体上位于前低洼凹槽上分别通过压纹的形式设有前压纹槽。
进一步的,所述后低洼凹槽呈圆弧状且圆弧开口方向朝向主吸收部,所述前低洼凹槽呈圆弧状且圆弧开口方向朝向主吸收部。
通过采用前述技术方案,本发明的有益效果是:
1、本发明在卫生巾的吸收芯的前端设置前低洼凹槽、后端设置后低洼凹槽,从而当本体弯曲时,所述本体的前端部沿前低洼凹槽处形成前弯折部,所述本体的后端部沿后低洼凹槽处形成后弯折部,由于前弯折部的弯折需求是比较小的,可以设置一个前低洼凹槽,而后低洼凹槽的弯折需求是比较大的,可以设置多个,这样的情况下,本体上位于各后低洼凹槽的侧边上向外设有折痕线,所述折痕线通过压制的形式形成,所述折痕线由后低洼凹槽向吸收芯周沿延伸但不穿透,所述折痕线的深度由后低洼凹槽向吸收芯周沿逐渐变小,所述折痕线的最深深度小于后低洼凹槽的深度,所述折痕线由内向外且由后端部向前端部倾斜。折痕线的设置,可以实现弯折形式的预成型,从而使得本体弯折朝向折痕线设置的形式,而且由于人体形态的差异,折痕线只是作为一个辅助弯折的存在,从而使得本体弯折能够更加趋向贴合于人体。
2、弹性体的设置,可以使得后低洼凹槽的弯折呈现一个主动性,也即在穿戴时,弹性体配合折痕线会形成一个主动的弯折状态,使得人体在进行动作时,其弯折状态会随着人体而变动,呈现一个主动贴合的状况,从而使得贴合性能的大大增强。而且,弹性体又会盖合后低洼凹槽,防止因为多个后低洼凹槽的存在,而使得人体产生细微的不适感,使得紧贴感、饱满感更明显,从而实现较好的穿着舒适性。
3、穿透孔的设置,可以使得弹性体的张紧不会给人较强的束缚绷紧感觉。穿透孔是成横向的长条孔,其宽度最大可以为3mm,最小可以为1mm。而且穿透孔是芯层三至五个竖排的,各竖排沿本体的宽度方向间隔设置,位于同一竖排内的相邻两穿透孔之间的间距由靠近本体中部的一侧向另一侧逐渐增大,这样可以使得穿透孔并不会对弹性体造成较大的破坏性,穿透孔本身会降低弹性体的张紧性能,但是仍然能够实现张紧的目的,并且当人体扭动、动作时,各个穿透孔会呈现不同大小的开合,从而形成柔软贴合的目的。
4、后导流槽、后压纹槽、后连接凹槽、后连接压纹槽的设置,可以实现导流、贴合的效果,从而使得各个后低洼凹槽之间形成连通,既可以导流,又能够实现较好的弯曲性能。
5、后导流槽、后压纹槽、后连接压纹槽均为间断线状,所述后导流槽、后压纹槽、后连接压纹槽各自不相交,这样可以防止其形成刚性,提高卫生巾的柔软度,而且可以有效提高吸收效果。
6、前导流槽、前压纹槽均为间断线状,且设置的目的同样是防止其形成刚性,提高卫生巾的柔软度,而且可以有效提高吸收效果。

具体实施方式
现结合附图和具体实施方式对本发明进一步说明。
参考图1至图4,本实施例提供一种符合人体工学的一次性卫生巾,包括本体1,所述本体1包括透液性表层2、不透液性底层4、设于透液性表层2和不透液性底层4之间的吸收芯3,所述本体1包括前端部1a、中部1b、后端部1c,所述吸收芯3内位于中部处设有一主吸收部31,所述主吸收部31的吸收性能大于吸收芯3除主吸收部31外的吸收性能,本体1上位于主吸收部31的侧沿上通过压纹的形式形成导流槽5,所述导流槽5通过压制透液性表层2陷入吸收芯3而形成,所述吸收芯3位于前端部1a上设有一个沿宽度方向设置的前低洼凹槽6,所述吸收芯3位于后端部上设有三个沿宽度方向设置的后低洼凹槽7,在数量选择时,前低洼凹槽、后低洼凹槽均可以根据实际需要进行选择。所述前低洼凹槽6处的吸收率为吸收芯3除主吸收部31外区域的吸收率的60%,该数值也可以是0%~75%之间的其他数值,所述后低洼凹槽处的吸收率为吸收芯除主吸收部外区域的吸收率的60%,该数值也可以是0%~75%之间的其他数值,由于吸收芯的吸收率除了主吸收部外是均匀分布的,其吸收率的大小也即为前低洼凹槽、后低洼凹槽的深度,当吸收率为0时,前低洼凹槽、后低洼凹槽是呈现贯穿状态的。
所述本体1上位于后低洼凹槽7的左侧、右侧、后侧分别通过压纹的形式设有后导流槽71。所述本体1上位于后低洼凹槽7上分别通过压纹的形式设有后压纹槽72。所述吸收芯3上沿中心线处设有用于连接相邻两后低洼凹槽7的后连接凹槽73。所述本体1上位于后连接凹槽73处通过压纹的形式设有后连接压纹槽74。所述后导流槽71、后压纹槽72、后连接压纹槽74均为间断线状,所述后导流槽71、后压纹槽72、后连接压纹槽74各自不相交。所述本体1上位于前低洼凹槽6的前侧、左侧、右侧分别通过压纹的形式设有前导流槽61,所述本体1上位于前低洼凹槽6上分别通过压纹的形式设有前压纹槽62。所述后低洼凹槽7呈圆弧状且圆弧开口方向朝向主吸收部31,所述前低洼凹槽6呈圆弧状且圆弧开口方向朝向主吸收部31。后压纹槽与前压纹槽的设置可以使得材料实现较好的贴合。
当本体1弯曲时,所述本体的前端部1a沿前低洼凹槽6处形成前弯折部,所述本体的后端部1c沿后低洼凹槽7处形成后弯折部,所述本体1上位于各后低洼凹槽7的侧边上向外设有折痕线8,所述折痕线8通过压制的形式形成,所述折痕线8由后低洼凹槽向吸收芯周沿延伸但不穿透,所述折痕线8的深度由后低洼凹槽7向吸收芯3周沿逐渐变小,所述折痕线8的最深深度小于后低洼凹槽7的深度,所述折痕线8由内向外且由后端部1c向前端部1a倾斜,后弯折部的具体体现即为折痕线。
所述吸收芯1上设有用于覆盖后低洼凹槽7的弹性体9,所述弹性体9在本体长度方向上的拉伸比为1.1-1.2倍,所述弹性体9为弹性无纺布,采用SBS嵌段共聚物型制成,也可以采用聚烯烃型或聚氨酯制成,所述弹性体9的拉伸比由靠近本体1中心一侧向远离本体1中心一侧呈增大趋势,所述弹性体9上设有复数个穿透孔91,数个穿透孔91形成三排,其也可以是四个竖排或五个竖排,各竖排沿本体1的宽度方向间隔设置,位于同一竖排内的相邻两穿透孔91之间的间距由靠近本体1中部的一侧向另一侧逐渐增大,各竖排上的穿透孔91为沿横向的长条孔。
三个后低洼凹槽与后连接凹槽形成了一个连续的工字型结构,后低洼凹槽宽度2~15mm,长度10~60mm,后连续凹槽宽度2~10mm,长度10~70mm,本实施例中,后低洼凹槽宽度10mm,长度50mm,后连续凹槽宽度6mm,长度50mm。卫生巾的前低洼凹槽、后低洼凹槽、前压纹槽、后压纹槽破坏了卫生巾前后端的纵向刚性,使消费者在穿戴卫生巾时前后端更容易被弯折并贴合女性屁股弧度和阴部弧度,呈前后高中间低的形态;卫生巾前后端的前连接凹槽、后连接凹槽、前导流槽、后导流槽破坏了卫生巾前后端的横向刚性。由于各个槽体均呈现横向或纵向的排列结构,并且由于采用沿卫生巾的中心线的对称结构,使消费者在穿戴卫生巾时前后端受大腿挤压缘故,卫生巾沿纵向向面层方向轻微上折,呈左右高中间低的形态。所以,卫生巾在穿戴过程中前后左右均略高于中间阴道出血口位置,极大降低了经血外漏的风险。
前低洼凹槽、后低洼凹槽具有较好的导流作用,经血在到达横向凹陷位置时如同水遇沟渠会迅速沿横向凹陷向卫生巾左右扩散,增加了防止后漏的作用。而且前低洼凹槽、后低洼凹槽、前导流槽、后导流槽避开本体中部的主要吸收区域,一方面避免了卫生巾过度的可弯曲性导致的松散,另一方面保证了主要的经血吸收量。卫生巾在对应阴道出血口位置的卫生巾中部主要吸收位置设置了高吸收量的吸收层材料,主要吸收位置的吸收量几倍高于前后端非主要吸收位置。从而形成一个整体吸收性能、防漏性能、穿戴性能较好的卫生巾产品。
此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中,“多个”的含义是两个或两个以上,除非另有明确具体的限定。
