Description
本发明涉及排泄物处理用穿着物品构件的制造方法,这种物品是处理粪便等排泄物用的一次性尿布和大小便等失禁用的一次性尿布等。
现在,在制造一次性穿着物品时,为了节省材料、将连续的带条形成凹凸缘部地沿纵长中心线反复凹凸地切断,而且把这些分割带条切断成所要求的长度而形成构件,这种技术方案已是公知的,例如在日本专利公报特开平2-291857号中就公开了与这技术有关的方法。
在这份公报中公开了在连续的第1带条上施加沿纵长方向周期反复的凹凸切断线,由此形成第1和第2分割带条,把第1分割带条相对于第2分割带条、沿纵长方向按规定节距偏移使这些第1和第2分割带条的各个凹缘部和各个凸缘部分别彼此相对匹配,把匹配了的第1和第2分割带条的与上述凹凸缘部相反侧的各个外侧部与连续的第2带条的各个外侧缘相接合而形成复合带条。这种复合带条可用作穿着物品构件,例如一次性尿布的表面薄片或里面薄片,此外还可用作感压性紧固带。
上述公报提出的紧固带是一个端部接合到尿布本体上的接合部,与其相对着的另一个端部是非粘接性的捏住部,两个端部间是粘接性的粘紧部。由于这几部分构成的紧固带形成比较大的构件,因而若能缩小它的尺寸就能降低穿着物品的成本。
本发明的目的是通过在构成穿着物品的复合带条上合并地设置能用来卸下紧固部分的捏住部,提供一种能降低成本的穿着物品构件的制造方法
为了达到上述发明目的而作出的本发明的穿着物品构件的制造方法是如下的。
本发明的穿着物品构件的制造方法是在连续的第1带条上沿纵长方向、加上周期反复的凹凸切断线而形成第1和第2分割带条,使上述第1分割带条相对于上述第2分割带条沿纵长方向偏移规定的节距,从而使这第1和第2分割带条的上述各个凹缘部和凸缘部彼此匹配,把匹配了的第1和第2分割带条的与上述凹凸缘部相反侧的各侧缘部接合到连续的第2带条的各个外侧缘部上,由此形成复合带条,其特征在于:它包含下述工序,即,用上述切断线在上述凹缘部和凸缘部上分别形成能与上述第1和第2分割带条同时进行匹配的,比上述凹凸缘部小的第2凹缘部和凸缘部的工序;在上述第2凸缘部和/或它的附近形成能将上述穿着物品固定在穿着者脚周围用的紧粘区域的工序。
图1是穿着用品(一次性尿布)的局部破断的平面图,
图2中的(1)、(2)、(3)是表示复合里面薄片的制造工序的示意图,
图3是表示本发明的一个实施例的与图2(1)同样的图,
图4是表示本发明的另一实施例的与图2同样的图。
下面,参照着附图来说明本发明的穿着用品构件的制造方法。
图1表示作为本发明的穿着用品的一个例子的一次性尿布1的局部破断平面图,图中表示的是这尿布1处于从外侧看到的状态。尿布1由透液性表面薄片2、复合里面薄片3、夹在这两层薄片2、3之间的吸液性芯部4构成,两层薄片2、3从芯部4的周缘伸出的部分的内表面彼此间水密地结合。尿布1的长度方向上由前侧区域(前身裁片)6、后侧区域(后身裁片)7、位于两侧区域6、7之间的股下区域8构成,在前后侧区域6、7的左右两侧有向侧方延伸的叶片部10、11,在股下区域8的左右两侧有向尿布1的内侧弯曲的脚周缘凹入部12。后侧区域7的叶片部11的侧缘上有向侧方突出的捏住部15,在捏住部15和/或在其附近的里面有通过涂敷粘接剂而形成的粘紧区域16。凹入部12上有伸长状态的脚周缘弹性构件17,这构件17位于表面薄片和里面薄片2、3之间,至少与这些薄片中的一方的内表面相接合。在凹入部1 2的靠前侧区域6的部位有小的切口17。
图示实施例的表面薄片2是沿前后方向长的矩形无纺布或开口塑料薄片,复合里面薄片3是由矩形的中央薄片20和不能剥离地与其左右两则缘部接合的侧缘部薄片21、22构成。最好,中央部薄片20和侧缘部薄片21、22是不透液性的,若用通气不透液性的则更好。也可以做成中央部薄片20是不通气性的,侧缘部薄片21、22是通气性的。尤其是在芯部4的保水量和保水力较大时可把这些薄片20、21、22取成通气透液性的。可把塑料薄膜或无纺布用作这些薄片20、21、22。
在穿着具有这种结构的尿布1时,将粘紧区域16粘贴到前侧区域6的外面。这时,只要捏着捏住部15、即使位于它的基端部的粘紧区域16很很也能确实而且迅速地粘贴。而且,在没认清粘紧区域16的部位之前,只要捏着捏紧部15就能将粘贴的粘紧区域16一一剥离。
图2是表示连续地制造复合里面薄片3的方法的平面示意图。在图2(1)中,连续的第1带条50实质上有平行的侧缘51a、51b,借助切断线53形成与纵长方向中心线52相关的凹凸部,通过使这切断线53向纵长方向延伸、形成有凹缘部54a和凸缘部54b的第1和第2分割带条50a、50b。如图2(2)所示,使第1分割带条50a相对于第2分割带条50b沿纵长方向偏移1/2×n(n为奇数)节距地、将第1和第2分割带条50a、50b的各个凹缘部54a及各个凸缘部54b彼此匹配,而且使第1分割带条50a位于第2分割带条50b的右侧地平行移动后,使各个凹凸缘部54a、54b位于外侧,使侧缘51a、51b位于内侧。连续的第2带条60实质上有平行的侧缘61a、61b。使第2带条60位于相互平行的第1和第2分割带条50a、50b的中央、使侧缘51a及其附近部分重叠在第2带条60的侧缘61b及其附近部分上,而且使侧缘51b及其附近部分重叠在第2带条60的侧缘61a及其附近部分上,而且不能剥离地接合后,形成连续的复合带条70。然后,当用使凸缘部54b上下分成两部分的第2切断线71切断复合带条70时,就形成图2(3)所示的1个尿布1的复合里面薄片3。第1和第2分割带条50a、50b在第2切断线71的下方设有由比凸缘部54b小的凸缘构成的第2凸缘部55。在图2(1)中,这种第2凸缘部55是通过使凸缘部54a形成切口而形成,由此构成图1的复合里面薄片3的捏住部15。而且在把第1的第2分割带条50a、50b形成复合里面薄片3之前的工序中,在第2凸缘部55和/或它的附近部分的内表面上涂敷上粘接剂或者接合上粘接性胶带,由此形成粘紧区域16。最好把剥离纸临时接合在粘紧区域16的粘接性表面上、对这粘紧区域16进行保护。这里省略对此图示。
使这样得到的连续复合带条70或者个别复合里面薄片3与同样地连续或个别供给的表面薄片2一起把芯部4覆盖,如果这是在连续复合带条70的场合下,则在覆盖后通过用第2切断线71切断就形成1块尿布。从图1或图2(3)可见,由于在这种尿布1上,通过稍稍将股下区域8的侧缘部12切一小口就能形成第2凸缘部55(15),因而形成这种第2凸缘部55、即形成捏住部15就不再需要别的构件。而且,这样通过切口加工对尿布1的穿着感觉一点不会影响,如果认为由此引起对肌肤刺激时,则可加宽表面薄片2的幅度,使它的左右侧缘达到股下区域8的侧缘。
在本发明中,也可用图2的工序,替代图1、图2所示的复合里面薄片3的制造表面薄片2,由此在表面薄片2上形成捏住部15。这时,把第2带条60替换成透液性的,把里面薄片3替换成与图1的表面薄片2相同的形状。
图3是表示与图2不同式样的第1和第2连续带条50a、50b的平面图。在这些带条50a、50b上,通过将凸缘部54b的局部侧缘57形成切口而在其上下形成第2凸缘部55,在凹缘部54a上形成与此切口相对应的凸部56。
图4是表示本发明的另一实施例的与图2同样的图。图4(1)所示的第1带条50是幅度较宽的下层带条81和幅度较窄的上层带条82的叠层体,两个带条81、82在幅度方向间歇地延续、在长度方向,由相互平行的多条接合线83形成不能剥离的一体。用切断线53和第2切断线71切断的第1带条50如图4(2)所示地匹配后形成第1和第2分割带条50a、50b。通过把下层带条81与第2带条60(图中没表示)接合,这些带条50a、50b就形成复合里面薄片3或复合表面薄片。在复合表面薄片场合下,下层带条81上使用透液性的,上层带条82上使用不透液性的,这时,即使把下层带条81覆盖在尿布1的吸液性芯部4的上面,至少不会妨碍体液向芯部4浸透。在下层带条81和上层带条82是纤维带条,在它们的纤维沿纵长方向取向场合下,如图所示地沿幅度方向形成长的接合线时能使这些带条的幅度方向的拉伸强度提高。另外,由于这些接合线无论在带条81、82的幅度方向或者纵长方向相互间隔着,因而这些接合线的设置会使第1带条50的刚性有所提高。
本发明中可把粘接性的粘紧区域16用商品名称为尼龙搭攀的雌雄一对紧固面的一方,把这搭攀的另一紧固面安装在前侧区域6的外面的所要求部位上。构成尿布1的各种构件除了用热融型粘接剂接合外,如果构件是热熔融性材料,这可用焊接将其接合。
本发明的穿着用品的制造方法,由于通过将股下区域的侧缘部局部切口而形成容易着脱该物品粘紧区域用的捏紧部,因而就不必使用别的构件来形成这捏紧部,也不必如现有技术那样地为此而把尼龙搭攀类紧固基材做得特大,因而能削减制造这穿着物品的成本。
