Description
技术领域
本发明涉及尿垫、女性失禁用垫等一次性使用的体液处理用品。
背景技术
日本特开平6-178795号公报揭示的吸收性物品,备有矩形的插入垫,该垫具有长度方向的前后腰围区域和位于这些前后腰围区域之间的裆下区,由尿布罩和吸收性材料构成,上述尿布罩的两侧缘部安装着朝长度方向延伸并向上方立起具有特性的一对保持翼,上述吸收性材料配置在罩的上面即保持翼之间。垫由吸收性芯、覆盖芯的透水性薄片形成。
日本特开平8-289902号公报揭示了一种一次性使用尿布。该一次性使用尿布具有透液性面层、不透液性里层和夹在该两层之间的吸液性芯,透液性面层由中央部层和分体的侧部层构成。在芯的侧缘部外侧附近向长度方向延伸的侧部层形成一对具有向上立起特性的护翼。侧部层具有朝尿布长度方向延伸的基部、从基部朝尿布的宽度方向内方延伸并以伸长状态安装着弹性部件的内侧部、从基部朝尿布的宽度方向外方延伸的外侧部。在从中央部层的两侧缘部向宽度方向外方延伸的里层和侧部层相互重合的状态下,基部和外侧部中的侧部层的内面固定在里层的上面。侧部层的前后端部向尿布的宽度方向内方倒伏,前后端部的内面固定在面层的上面。
将日本特开平6-178795号公报揭示的吸收性物品和特开平8-289902号公报揭示的尿布组合,可以想出以下的构造。即,吸收性物品具有垫本体和侧部层,该垫本体的吸液性芯夹在透液性面层与不透液性里层之间、在从面层两侧缘部向宽度方向外方伸出的里层、侧部层相互重合的状态下,把基部和外侧部中的侧部层的内面固定在里层的上面,在侧部层的前后端部朝尿布宽度方向内方倒伏的状态下,把前后端部的内面固定在面层的上面。
但是,由于侧部层的内侧部,容易朝接近面层上面的侧的方向移动,所以,即使弹性部件收缩,侧部层的立起仍不充分,有时排泄物或经血等体液会越过侧部层漏出。另外,由于在垫的两端缘部没有防止体液泄漏的构造,所以不能防止体液从两端缘部泄漏。
发明内容
本发明的目的是提供一种护翼容易立起、并可防止体液从周缘部泄漏的一次性使用的体液处理用品。
为了实现上述目的,本发明的一次性使用体液处理用品,由在透液性面层和不透液性里层之间夹着吸液性芯的叠层片体构成,该片体具有彼此相对并朝长度方向延伸的两侧缘部和彼此相对并朝宽度方向延伸的两端缘部;其特征在于,

具体实施方式
下面,以安装在尿布罩内面使用的吸收性垫为例,参照附图详细说明本发明的一次性使用体液处理用品。
图1是由叠层片体1构成的垫的局部剖切立体图。片体1由透液性面层2、不透液性里层3和夹在面层2与里层3之间并与层2、3中至少一方的内面接合的吸液性芯4形成,具有彼此相向并朝长度方向延伸的两侧缘部1a、和彼此相向并朝与长度方向交叉的宽度方向延伸的两端缘部1b。
在片体1的两侧缘部1a,以伸长状态安装着膜状弹性部件6的一对侧部层5朝片体1的长度方向延伸。在片体1的两端缘部1b,以伸长状态安装着膜状弹性部件8的一对覆盖层7朝片体1的宽度方向延伸。片体1具有被侧部层5和覆盖层7围绕的开口13,面层2从开口13露出。
侧部层5由无纺布形成,具有侧部5a、侧部5b和前后端部5c。侧部5a位于片体1的上面侧,朝片体1的长度方向延伸,在片体1的两端缘部1b之间不固定在面层2上也不固定在里层3上。侧部5b位于片体1的下面侧,朝片体1的长度方向延伸。前后端部5c位于片体1的上面侧并且位于片体1的两端缘部1b。
覆盖层7由无纺布形成,具有部分7a、部分7b和两侧部分7c。部分7a位于片体1的上面侧,朝片体1的宽度方向延伸,在片体1的两侧缘部1a之间均不固定在面层2上也不固定在里层3上。部分7b位于片体1的下面侧,朝片体1的宽度方向延伸。两侧部分7c位于片体1的上面侧并位于片体1的两端缘部1b的两侧。
图2是图1的A-A线断面图。侧部层5的侧部5b,具有朝片体1长度方向延伸的弯折部9,在弯折部9处侧部5b的内面相互重合地弯折着。侧部5b具有非固定侧部5b1和固定侧部5b2,非固定侧部5b1从片体1的两侧缘部1a朝宽度方向内方延伸。固定侧部5b2从弯折部9朝片体1的宽度方向外方延伸。固定侧部5b2的与里层3相对的面通过粘接剂固定在里层3的下面上。侧部5a包着弹性部件6地朝片体1内侧折叠,弹性部件6在被侧部5a覆盖的状态被安装着。
非固定侧部5b1和固定侧部5b2,在弯折部9处相互地要返回直状。随之,侧部5a朝着离开片体1上面的方向移动,所以,侧部层5容易从片体1的上面朝上方立起。当片体1以其内面为内侧地沿长度方向弯曲时,弹性部件6收缩,侧部层5立起,侧部层5的侧部5a和面层2形成朝片体1内侧开口的袋P1。
由于非固定侧部5b1不固定在里层3上也不固定在固定侧部5b2上,所以侧部层5的可立起高度为片体1宽度方向中侧部5a的长度和非固定侧部5b1的长度之和。因此,在使用中,即使片体1从使用者肌肤离开相当于侧部5a的长度,由于非固定侧部5b1的长度有富余,所以,能保持侧部层5与使用者腿部周围相接的状态。
图3是图1的B-B断面图。图4是图1的C-C线断面图。覆盖层7的部分7b,具有朝片体1宽度方向延伸的弯折部11,在弯折部11中部分7b的内面相互重合地弯折。部分7b具有非固定部分7b1和固定部分7b2。非固定部分7b1从片体1的两端缘部1b朝长度方向内方延伸。固定部分7b2从弯折部11朝片体1长度方向外方延伸。固定部分7b2的与里层3相对的面通过粘接剂12固定在里层3的外面上。部分7a包着弹性部件8地朝片体1的内侧折叠,弹性部件8以被侧部7a覆盖的状态被安装着。
在侧部层5的前后端部5c朝片体1宽度方向内方倒伏、覆盖层7的两侧部分7c朝片体1长度方向内方倒伏、侧部层5的前后端部5c和覆盖层7的两侧部分7c相互重合的状态下,前后端部5c的下面和两侧部分7c的上面相互固定着。也可以是侧部层5的前后端部5c的上面和覆盖层7的两侧部分7c的下面相互固定。
非固定部分7b1和固定部分7b2,在弯折部11处彼此欲要返回直状,随之,部分7a朝离开片体1上面的方向移动,所以,覆盖层容易从片体1的上面立起。当弹性部件8收缩时,覆盖层7朝片体1的上方立起,部分7a和面层2形成朝片体1内侧开口的袋P2。
由于非固定部分7b1不固定在里层3上也不固定在固定部分7b2上,所以,覆盖层7的可立起高度是片体1长度方向中的部分7a的长度和非固定部分7b1的长度之和。另外,在使用中,即使片体1从使用者肌肤离开相当于部分7a的长度,由于非固定部分7b1的长度有富余,所以可保持覆盖层7与使用者肌肤相接的状态。
侧部层5的侧部5a和覆盖层7的部分7a彼此具有障壁的作用,袋P1和袋P2具有收容从芯4漏出的排泄物的功能,所以,可防止在片体1的两侧缘部1a和两端缘部1b泄漏排泄物。
图5是把图1的片体安装在尿布罩30上的平面图,剖切罩30的局部进行表示。尿布罩30是内面层31和外面层32的叠层体,呈计时砂漏型。内面层31由塑料薄膜构成,外面层32由无纺布构成。罩30具有沿长度方向的前后腰围区域35、37和位于该前后腰围区域35、37间的裆下区36,裆下区36的两侧朝罩30的内侧弯曲。
在裆下区36的侧缘部,朝长度方向延伸的弹性部件以伸长状态安装在内外面层31、32中至少一方的内面。从后腰围区域37到裆下区36,片体1通过粘接剂(图未示)可取下地粘接在罩30的内面上。可适当变更片体1的安装位置,通过变更安装位置可作为尿垫用或作为卫生巾用。
罩30,在后腰围区域37的两侧缘部具有带式搭扣34,由于采用搭扣34,与使用已往的一次性使用尿布时同样地,穿上片体1和罩30的组合体,使片体1的开口13的大体中央位于使用者的肛门处。
这样使用片体1时,排泄物排泄到开口13中,不会弄脏罩30。在扔掉排泄物时,不必拿着大的罩30,只要拿着小的片体1即可,比较方便。
片体1中,由于安装在两侧缘部1a上的侧部层5和安装在两端缘部1b上的覆盖层7成为防止体液泄漏的障壁,所以,在罩30的两侧缘部不必安装具有从罩30的上面向上方立起特性的护翼。
面层2是采用无纺布或开孔塑料薄膜等透液性的薄片,最好采用透液性、疏水性的薄片。里层3是采用不透液性的塑料薄膜、塑料薄膜和疏水性无纺布的叠层片,最好采用透气不透液性薄片。
侧部层5和覆盖层7是采用透气不透液性的无纺布或透气不透液性的伸缩性无纺布。采用伸缩性无纺布时,把侧部层5以朝长度方向伸长的状态固定在片体1上,把覆盖层7以朝宽度方向伸长的状态固定在片体1上,可不必在侧部层5的侧部5a和覆盖层7的部分7a上安装弹性部件6、8。
无纺布可采用射流喷网型、针刺型、熔吹型、热粘型、纺粘型、化学粘型等无纺布。单位面积重量为15~80kg/m2,最好为20~60kg/m2。无纺布的构成纤维,可采用聚烯烃系、聚酯系、聚酰胺系的各纤维、聚乙烯/聚丙烯或聚酯的复合纤维等。
芯4,主要是将纸浆(フラツフパルプ)和超吸收性水凝胶粒子压缩后,将其整体用绵纸等透水层覆盖住而构成的。
这些层2、3、5、7的固定、弹性部件6、8的安装,除了用热熔粘接剂等的粘接剂或粘着剂外,还可以利用热熔敷技术。
本发明也可以不使用尿布罩30地把处理用品本身直接安装在内裤上使用。
根据本发明的体液处理用品,可根据用品的安装位置,作为尿垫、粪便垫或卫生巾使用,从用品的开口收容到用品内部的排泄物或经血等体液,透过面层被芯吸收。
侧部层和覆盖层由于欲要朝着离开片体上面的方向移动,所以侧部层和覆盖层容易从片体的上面朝上方立起。当侧部层立起时,面层和侧部层的侧部形成朝片体内侧开口的袋;当覆盖层立起时,面层和覆盖层的部分形成朝片体内侧开口的袋,因此,可防止在片体的两侧缘部和两端缘部泄漏排泄物。
