Abstract

一种生理用卫生巾,具有上下重合的上层片11和下层片12,上层片11可朝卫生巾1的纵向弹性伸缩地形成,在下层片12设置翼部13。由此可防止带翼部生理用卫生巾的横向泄漏。

Description

生理用卫生巾
本发明涉及一种生理用卫生巾。
在日本专利公报特开平2-7956号中公开的生理用卫生巾为具有翼部的卫生巾的改良品,在侧缘部形成朝卫生巾纵向具有伸长性的片。该片在从穿用短裤的腿周开口缘部伸出到开口中的部分折叠到短裤的下裆区域外面时伸长,紧密接合到弯曲的开口边缘。折叠的片可通过涂抹于片的粘合剂固定于短裤外面。
在上述公知的卫生巾中,通过由片覆盖穿用短裤的开口缘部,可防止经血对其边缘部的污损。然而,在这样穿用的上述公知卫生巾中,难于阻止从短裤横向漏出的经血沿大腿流动。
本发明所要解决的课题在于,在可固定于穿用短裤外面的卫生巾中,防止横向漏出的经血沿大腿流动。
为了解决上述课题,本发明的前提为这样一种生理用卫生巾,该生理用卫生巾由透液性表面片料、不透液性背面片料、及介于这两种片料间的吸液性芯层构成,具有朝纵向延伸的一对侧缘部、以及朝横向延伸的一对端缘部。
在上述前提下,本发明的特征在于:上述侧缘部由可朝上下离开地重合的上层片和下层片构成,上述上层片具有上述卫生巾全长的1/2~1/1的长度、在上述宽度方向上最大10~30mm的宽度,可朝上述纵向弹性地伸长120~300%,上述下层片朝上述卫生巾的横向外方延伸,具有从上述上层片外侧缘部延伸、在下面涂抹有粘合剂的翼部。
在本发明的最佳实施形式中,上述上层片由可朝上述纵向和横向中至少上述纵向弹性伸缩的片料形成。
在另一实施形式中,上述上层片在上述纵向于非伸缩性片料上安装朝上述纵向伸长的弹性构件,在该片料上形成沿上述纵向反复构成山和谷的多个褶裥。
在另一实施形式中,上述上层片在非伸缩性片料的上述纵向间断地配置上述褶裥的密集区域。
在再另一实施形式中,上述下层片可沿上述纵向弹性地伸长。
对附图简单说明如下:
图1为卫生巾的局部剖切透视图。
图2为图1的II-II线断面图。
图3为处于穿用状态的卫生巾的断面图。
图4为示出实施形式一例的与图1相同的图。
图5为示出实施形式另一例的与图1相同的图。
下面根据附图说明本发明的生理用卫生巾的详细内容。
图1中用局部剖开透视图示出的生理用卫生巾1设有透液性表面片料2、不透液性背面片料3、介于这些表背面片料2、3间的吸液性芯层4,并具有朝纵向延伸的一对侧缘部6、朝横向延伸的一对端缘部7。表背面片料2、3在从芯层4的周缘延伸出并重合的部分相互接合。侧缘部6具有上层片11和下层片12,该上层片11由片料10和弹性构件9构成,该片料10具有朝横向延伸的山和谷沿纵向反复交互形成的多个褶裥8,该弹性构件9沿纵向延伸,该下层片12位于片11的下侧并设有翼部13。芯层4呈沙漏计时器形。
图2示出图1的II-II线断面。上层片11的片料10为非伸缩性或伸缩性片料,该片11的内侧缘部16在接合线17接合于表面片料2的侧缘部和/或从该侧缘部延伸到侧方的背面片料3。在上层片11的外侧缘部18,在从片料10朝下方折回的部分的内侧,以伸长状态贴合弹性构件9,由该构件9的收缩形成褶裥8。贴合弹性构件9时的伸长应力最好为10~150g。由图1、图2可知,内侧缘部16的接合线17沿芯层4的侧缘朝纵向延伸,并朝卫生巾1内方凸起地弯曲,两端部分与外侧缘部18交叉。该上层片11的纵向尺寸B在卫生巾1的全长A的1/2~1/1范围,尺寸B最好可在伸长时达到200mm以上。上层片11的横向最大尺寸C最好在10~30mm的范围。上层片11的外侧缘部18间的尺寸D在60~120mm的范围,更好的情况是在80~100mm的范围。
下层片12的基缘部14由从芯层4的侧缘延伸到侧方的表面片料2和背面片料3形成。两片料2、3在芯层4的侧缘近旁重合,并通过热融粘合剂21相互接合。背面片料3从表面片料2的侧缘进一步朝侧方延伸,达到上层片11的外侧缘部18后,一部分进一步延伸形成翼部13。在翼部13的下面涂抹粘合剂22,由剥离纸23保护粘合剂22。
图3为图2的卫生巾1处于穿用状态时的图。卫生巾1放置于穿用短裤26的下裆区域内面,下层片12重合到下裆区域的外面,翼部13通过粘合剂22固定在其外面。通过折合下层片12,覆盖穿用短裤26的腿周开口缘部27,防止缘部27被经血弄脏。
上层片11沿短裤26的开口缘部27朝下折曲,紧密接合在穿用者的大腿28。上层片11在朝下折曲时褶裥8和弹性构件9朝卫生巾1的纵向伸长,所以,存在要从图示的状态恢复到图2的原来状态的倾向。结果,上层片11强有力地紧密接合于大腿28。在上层片11的该作用下,从卫生巾1的横向漏出的经血不会沿大腿28内侧而流下。
图4为示出本发明实施形式一例的与图1相同的图面。在该卫生巾1中,芯层4为矩形,形成沿芯层4的侧缘纵向伸长的大体为矩形的上层片11和具有翼部13的下层片12。上层片11设置在卫生巾1的大体全长,具有10~30mm的宽度,但与图1的情形不同,没有褶裥8。作为其替代,在该片11使用弹性片料10A,该弹性片料10A在卫生巾1的纵向和横向中的至少纵向可伸长120~300%。下层片12与图2相同地形成。该卫生巾在穿用时成为图3的状态。弹性片料10A可使用天然橡胶或合成橡胶等的伸缩性片料。
图5为示出本发明的实施形式的一例的与图1相同的图。在该卫生巾1的上层片11中,在纵向使用非伸缩性的片料10B,在该片料10B沿纵向间断地形成反复出现山和谷的褶裥8的密集区域15。上层片11在外侧缘部具有弹性构件9,当如图3那样穿用卫生巾1时,褶裥8与弹性构件9朝纵向伸长,紧密接合于大腿28。
在本发明中,可在表面片料2使用无纺织物或开孔塑料膜。在背面片料3可使用塑料膜。芯层4可使用粉碎纸浆粕或粉碎纸浆粕与高吸水性聚合物的混合物。上层片11可使用伸缩性或非伸缩性无纺织物或塑料膜,该无纺织物或塑料膜最好具有通气性,更好的场合具有通气性而且具有吸汗性。下层片12如图示例那样朝侧方长长延伸出地形成背面片3,还在表面片料2和/或背面片料3接合形成与表背面片料2、3另成一体的无纺织物或塑料膜。下层片12易沿穿用短裤腿周折曲如图1所示那样使基缘部14弯曲,另外,使外侧缘部29(参照图1)朝卫生巾1的内方弯曲。下层片12朝侧方延伸出的尺寸可与上层片11的尺寸无关系地决定。但是,翼部13具有不论下层片12处于什么场合都可达到穿用短裤下裆区域的大小。在下层片12也可带有朝纵向的弹性伸缩性。在表面片料2、背面片料3、上层片11、及下层片12的相互接合中,除热融粘合剂等的粘合剂外,可利用热融胶合法等胶合技术。
本发明的生理卫生巾具有上层片和下层片,将上层片强有力地紧密接合于穿用者的大腿,将下层片折叠到穿用短裤下裆区域外面,可将翼部固定在其外面,所以,该卫生巾同时具有带翼部卫生巾的使用方便性和阻挡经血沿大腿流动的效果。
