By packaging the absorbent articles individually, the absorbent articles can be carried in a simple, hygienic, and easy-to-carry state.
例如,在專利文獻1記載有一種吸收性物品的個包裝體,係沿著個包裝折線折疊具有表面材與裏面材和介設在該兩材的吸收體之吸收性物品的個包裝體,其中,在前述吸收性物品的表面材側形成有周狀的防漏溝,在該周狀的防漏溝,是具有在前述個包裝折線的位置在俯視觀看進入到周內方的縮窄部,且具有在較前述周狀防漏溝內側,與前述個包裝折線大致平行朝寬幅方向延伸的弧狀的中央溝,在具有該中央溝的區域,具有前述縮窄部及個包裝折線。
For example,
專利文獻2記載有一種吸收性物品,係具備液體保持性的吸收體以及配置在該吸收體的肌膚對置面側
的表面薄片及配置在該吸收體的非肌膚對置面側的裏面薄片,並具備有吸收性本體,其是具有:裝用時和裝用者的排泄部對置配置的排泄部對置部、較該排泄部對置部被配置在裝用者的腹側的前方部、以及較該排泄部對置部被配置在裝用者的背側的後方部,且具有相當於裝用者的前後方向的縱向以及與此正交的橫向之吸收性物品,其中,前述裏面薄片具有透濕性,前述吸收體,是由吸收性薄片的層積體形成,在前述排泄部對置部具有排泄部細縫區域,該區域是形成貫穿最接近前述表面薄片的吸收性薄片的細縫朝前述縱向及前述橫向的兩方向分散的狀態,前述吸收體,是在前述排泄部對置部具有多層部,該多層部,是吸收性薄片的層積片數比位在其周圍的部分更多的部分,在前述多層部,是具有貫穿前述該吸收體的貫穿細縫作為前述細縫,在較該多層部的周緣位於外方,吸收性薄片的層積片數較該多層部少的部位具有貫穿最接近前述表面薄片的吸收性薄片,不貫穿該吸收體的非貫穿細縫。

[專利文獻2]日本特開2015-024000號公報 [Patent Document 2] Japanese Patent Application Publication No. 2015-024000
在專利文獻1所揭示的吸收性物品的個包裝體,吸收性物品具有:在其寬幅方向上延伸的弧狀的中央溝、以及個包裝體的折線,其被形成在具有中央溝的區域,且與中央溝大致平行延伸。因此,專利文獻1的吸收性物品,是因上述中央溝與其他的部分的剛性差,在中央溝之處容易被折疊。另一方面,專利文獻1的吸收性物品,是將中央溝熔接在位在其上下的位置的薄片時,塑性變形,所以,裝用者開封個包裝體,將吸收性物品展開成平面形狀時維持折疊形狀,又,中央溝沒有熔接在位在其上下位置的薄片時,發生層內剝離而產生皺紋,所以,即使在任何情況在裝用時也不易形成平面形狀。其結果,專利文獻1的吸收性物品,是安裝感差,會有經血等的液體容易洩漏的傾向。
In the individual package of the absorbent article disclosed in
又,專利文獻2所揭示的吸收性物品,雖具有在其縱向(長方向)或橫向(寬邊方向)上延伸的複數個細縫,可是,具有縱向的細縫時,沒有折疊成個包裝形態時的彎折起點,會有折疊線的位置容易偏離的傾向,而且,專利文獻2所記載的吸收性物品,是裝用時容易以細縫為軸朝吸收性物品的寬幅方向折疊,而會有液體容易從歪扭的吸收性物品漏出的傾向。又,橫向具有細縫時,若吸收性物品的剛性太低,即使開封個包裝體欲將吸收性物品展開呈平面形狀時也保持折疊形狀的狀態,裝用前使用者必須進行讓吸收性物品回復到平面形狀的作業。
In addition, the absorbent article disclosed in
本發明之目的在提供一種,容易形成折疊形狀,且也容易回復到平面形狀,改善折線區域中的安裝感的同時,液體不易洩漏的吸收性物品的個包裝體。 The object of the present invention is to provide an individual package of absorbent articles that is easy to form a folded shape, and is also easy to return to a flat shape, improves the installation feeling in the fold area, and does not easily leak liquid.
本發明者們找出一種吸收性物品的個包裝體,係具有長方向及寬幅方向,且在前述寬幅方向上延伸的折線區域藉由將具備吸收體的吸收性物品與包裝薄片一起折疊而被形成的吸收性物品的個包裝體,其特徵為:前述吸收體具有一方的面、與另一方的面,在前述折線區域,具備至少1個以上從前述一方的面切入到前述吸收體的厚度方向中途所形成的細縫部,前述細縫部在前述一方的面具有在前述寬幅方向上延伸的開口部,前述吸收體,是至少在與前述細縫部在前述吸收體的厚度方向重複的位置具備有與前述細縫部在前述吸收體的厚度方向不重複的部分相較下為高密度部。 The present inventors have found an individual packaging body of an absorbent article, which has a longitudinal direction and a width direction, and a folding line area extending in the aforementioned width direction is achieved by folding the absorbent article with the absorbent body together with the packaging sheet The individual packaging body of the formed absorbent article is characterized in that the absorbent body has one face and the other face, and at least one or more cut-in from the one face to the absorbent body is provided in the fold line area The slit portion formed in the middle of the thickness direction of the slit portion, the slit portion has an opening extending in the width direction on the one surface, and the absorbent body is at least overlapping with the slit portion in the thickness direction of the absorbent body The position is provided with a high-density portion compared to the portion where the slit portion does not overlap in the thickness direction of the absorbent body.
本發明的個包裝體中的吸收性物品,是在折線區域至少具備1個以上的細縫部,該細縫部,是被設在吸收體的寬幅方向上,在吸收體的折線區域,在設有細縫部的部分與這以外的部分產生剛性差,折疊成個包裝形態時,細縫部成為彎折起點,容易形成折疊形狀。又,細縫部只形成到吸收體的厚度方向的中途,且,由於長方向中的連續的區域存在,所以,回復到平面形狀的力(復原力)作用,也容易回復到平面形狀。再者,本發明的吸收 性物品,由於是至少在與細縫部在吸收體的厚度方向重複的位置具備高密度部,所以,在該高密度部與其周邊部分之間剛性差產生,折疊成個包裝形態時,高密度部成為彎折起點,容易形成折疊形狀。又,前述高密度部,因為提高細縫部與在吸收體的厚度方向重複的位置中的部分的剛性,所以,回復到平面形狀的力(復原力)作用,也容易回復到平面形狀。如此,本發明的個包裝體中的吸收性物品,由於同時具備細縫部與高密度部,所以,兼具形成折疊形狀的容易性與回復到平面形狀的容易性的兩方。 The absorbent article in the individual package of the present invention is provided with at least one slit portion in the fold line area, and the slit portion is provided in the width direction of the absorbent body. There is a difference in rigidity between the part with the slit part and the parts other than this. When folded into a package form, the slit part becomes the starting point of bending, and it is easy to form a folded shape. In addition, the slit portion is formed only in the middle of the thickness direction of the absorber, and since there are continuous regions in the longitudinal direction, the force (restoring force) to return to the flat shape is applied to easily return to the flat shape. Furthermore, the absorption of the present invention The sex article has a high-density part at least at a position that overlaps the slit part in the thickness direction of the absorbent body. Therefore, there is a difference in rigidity between the high-density part and its peripheral part. When folded into a single package, the high-density part It becomes the starting point of bending and is easy to form a folded shape. In addition, since the high-density portion increases the rigidity of the slit portion and the portion overlapping in the thickness direction of the absorbent body, the force (restoring force) for returning to the flat shape is applied, and the flat shape is also easily restored. In this way, since the absorbent article in the individual package of the present invention includes both the slit portion and the high-density portion, it has both the ease of forming a folded shape and the ease of returning to a flat shape.
本發明的吸收性物品的個包裝體,是容易形成折疊形狀,且也容易回復到平面形狀。 The individual package of the absorbent article of the present invention can be easily formed into a folded shape and can easily return to a flat shape.

本實施形態中,吸收體9雖可使用讓高吸收性聚合物分散保持在含紙漿的纖維構造體者,可是本發明的吸收性物品所使用的吸收體,只要具有吸收保持經血等的體液的功能者就沒有特別的限制,除了讓高吸收性聚合物分散保持於上述含紙漿的纖維構造體者之外,可使用不織布等的任意的吸收性材料。又,以吸收體來說,藉由壓製等壓縮上述的吸收性材料者,也因為吸收體的剛性高,所以在衛生棉的使用中吸收體不易破裂,所以可適合使用。
In the present embodiment, although the
本發明的吸收性物品中,吸收體的基量,只要在一般所使用時的基量的範圍內則作為吸收性物品的吸收體就沒有特別的限制。 In the absorbent article of the present invention, the base amount of the absorber is not particularly limited as long as it is within the range of the base amount at the time of general use.
又,本實施形態中,被覆薄片10雖可使用聚烯烴系纖維(例如,聚乙烯、聚丙烯等)、聚酯系纖維
(例如,聚對苯二甲酸乙二醇酯等)等的合成纖維形成的不織布等的液透過性薄片,可是,本發明的吸收性物品所使用的被覆薄片,只要可讓經血等的體液透過者,則沒有特別的限制,除了上述的不織布以外,也可使用塑膠薄膜、織布等的任意的薄片材料。
In addition, in this embodiment, although the
被覆薄片由不織布、織布等的纖維構造體形成時,該纖維構造體的基量也只要在一般所使用時的基量的範圍內則作為適用於吸收性物品者的就沒有特別的限制。又,關於被覆薄片的厚度雖沒有特別的限制,可是理想是在0.1mm~5.0mm,更理想是在0.2mm~2.0mm。 When the covering sheet is formed of a fibrous structure such as a non-woven fabric or a woven fabric, the base weight of the fibrous structure is not particularly limited as long as the base weight of the fibrous structure is within the range of the base weight in general use. In addition, although there is no particular limitation on the thickness of the coating sheet, it is preferably 0.1 mm to 5.0 mm, and more preferably 0.2 mm to 2.0 mm.
本實施形態中,被覆薄片10至少一部分藉由熱熔解材等的任意的接著劑與吸收體9接合。吸收體9與被覆薄片10經由接著劑被接合,在衛生棉2的使用中,吸收體9及被覆薄片10不易以後述的細縫部作為起點破裂。又,本發明的吸收性物品中,因為將吸收體與被覆薄片一體化,所以,除了上述的接著劑之外,也可併用壓花等的壓著手段等。尤其,若在吸收體與被覆薄片的一體化使用壓花的話,因為吸收體與被覆薄片藉由複數個壓花銷所致的壓榨而被形成的複數個壓榨部被接合,所以,因吸收體與被覆薄片的分離造成吸收體歪扭,或破裂變的困難,並且在複數處形成纖維密度高的壓榨部,而使吸收體的剛性變高,在衛生棉的使用中因吸收體破裂這樣的情況不易發生。
In this embodiment, at least a part of the covering
本實施形態中,被覆薄片10雖被配置在表面
薄片7及吸收體9之間,可是本發明的吸收性物品所使用的被覆薄片,只要位在至少部分被覆吸收體的位置就沒有特別的限制,可按照所期望的吸收性能、剛性等配置在任意的位置,例如,被覆薄片即使被配置在吸收體及裏面薄片之間,也可以圍繞吸收體整體的方式被配置。
In this embodiment, the covering
此外,在本實施形態,雖說明衛生棉2具備被覆薄片10的構造,可是,被覆薄片不是必須的構成要素,例如,吸收體本身具有足夠的剛性時,衛生棉也可是去除被覆薄片的構成。
In addition, in this embodiment, although the structure of the
而且,如上述被接合的吸收體9及被覆薄片10,是至少在折線區域5內,在肌膚對置面具備有貫穿被覆薄片10從與前述被覆薄片10抵接的面被形成到吸收體9的厚度方向DT的中途部分的細縫部12,且具有在寬幅方向上延伸的開口部。如圖3所示,本發明的第1實施形態中,細縫部12在俯視觀看跨吸收體9及被覆薄片10的大致全面被配置。在本實施形態,複數個細縫部12的各細縫部在俯視觀看,相對於吸收體9及被覆薄片10的縱向(亦即,衛生棉2的長方向DL)朝垂直的橫向,亦即,與衛生棉2的寬幅方向Dw朝向平行的方向延伸。又,在寬幅方向中的同一線上,細縫部12與非細縫部120交替存在。
Moreover, the
本發明的吸收性物品中,細縫部的長度雖沒有特別的限制,可是理想是在3mm~50mm,更理想是在5mm~15mm。細縫部的長度若在3mm以上有助於吸收體 的剛性的降低,可容易折疊吸收體。另一方面,細縫部的長度若在50mm以下,在吸收體的寬幅方向端部留下沒有形成細縫部的部分,可發揮從折疊吸收性物品的狀態展開時的復原力,並且,裝用者裝用吸收性物品時,吸收體可維持能承受寬幅方向DW的壓力的程度的剛性。可是,若考慮到折線區域中的吸收性物品的容易折疊性,在寬幅方向佔據在同一線上的細縫部的合計長度的吸收體的寬幅方向的長度的比率,理想是在30~80%,更理想是在40~70%,更為理想是在50~60%。 In the absorbent article of the present invention, although the length of the slit portion is not particularly limited, it is desirably 3 mm to 50 mm, and more desirably 5 mm to 15 mm. If the length of the slit portion is 3 mm or more, the rigidity of the absorber can be reduced, and the absorber can be easily folded. On the other hand, if the length of the slit part is less than 50mm, the part where the slit part is not formed is left at the end of the absorbent body in the width direction, and the restoring force when the absorbent article is unfolded from the folded state can be exerted. When wearing an absorbent article, the absorber can maintain rigidity to the extent that it can withstand the pressure in the width direction DW . However, considering the ease of folding of the absorbent article in the fold line area, the ratio of the length of the absorbent body in the width direction that occupies the total length of the slits on the same line in the width direction is ideally 30 to 80% , The more ideal is 40~70%, and the more ideal is 50~60%.
如圖4及圖5所示,本實施形態中,細縫部12是從肌膚對置面貫穿被覆薄片10從與前述被覆薄片10抵接的面被形成到吸收體9的厚度方向DT的中途部分。
As shown in FIGS. 4 and 5, in the present embodiment, the
本發明中的吸收體的細縫部的深度雖沒有特別的限制,可是從吸收性物品的折疊容易性等的點,例如是在0.05mm~5.0mm,更理想是在0.1mm~3.0mm。又,細縫部的厚度在吸收體的厚度的70%以下,或是也可成為吸收體的厚度的一半以下。 Although the depth of the slit portion of the absorbent body in the present invention is not particularly limited, it is, for example, 0.05 mm to 5.0 mm, and more preferably 0.1 mm to 3.0 mm from the viewpoint of ease of folding of the absorbent article. In addition, the thickness of the slit portion is 70% or less of the thickness of the absorber, or may be half or less of the thickness of the absorber.
此外,在本說明書,細縫部的深度,是指沿著具有細縫部側的表面的平面、與細縫部中的最深部之間的距離,具體而言,是指由以下的測量方法所求取的深度。(1)在與細縫部的延伸的方向垂直相交的平面切斷具有細縫部的吸收體及被覆薄片(以下,稱為「吸收體等」)。(2)用掃描型電子顯微鏡等的電子顯微鏡觀察切斷後的吸收體等的剖面,測量位在任意的相鄰的2個細 縫部之間的最厚的厚度的部分(以下,稱為「最厚部」。)的厚度(mm)。(3)測量任意10處的最厚部的厚度(mm),以其平均值作為最厚部平均厚度(mm)。(4)使用電子顯微鏡照片或影像,以與吸收體等的具有細縫部的面相反側的面作為下側,將吸收體等載置在水平面時,將由接觸該水平面的部分形成的平面假設為假想底面,並且在與前述假想底面平行的平面,將位在來自前述底面的距離與前述最厚部平均厚度一致的位置的平面假設為假想基準表面,測量該假想基準表面到細縫部的最深部的距離(mm)。(5)針對任意10個細縫部,測量前述假想基準表面到細縫部的最深部的距離(mm),將其平均值作為細縫部的深度(mm)。 In addition, in this specification, the depth of the slit portion refers to the distance from the deepest part of the slit portion along a plane having the surface on the side of the slit portion. Specifically, it refers to the following measurement method: depth. (1) The absorbent body and the covering sheet (hereinafter referred to as "absorbent body etc.") having the slit part are cut in a plane that intersects perpendicularly to the extending direction of the slit part. (2) Observe the cross-section of the cut absorber with an electron microscope such as a scanning electron microscope, and measure the position of two adjacent thin The thickness (mm) of the thickest part between the seams (hereinafter referred to as "thickest part"). (3) Measure the thickness (mm) of the thickest part at any ten locations, and use the average value as the average thickness (mm) of the thickest part. (4) Using electron micrographs or images, when placing the absorber or the like on a horizontal surface with the surface opposite to the surface with the slit portion of the absorber etc. as the lower side, assume that the plane formed by the part that touches the horizontal surface is The imaginary bottom surface, and in a plane parallel to the aforementioned imaginary bottom surface, the plane located at the position where the distance from the aforementioned bottom surface coincides with the average thickness of the aforementioned thickest part is assumed to be the virtual reference surface, and the imaginary reference surface is measured to the deepest part of the sipe The distance (mm). (5) For any 10 sipes, measure the distance (mm) from the aforementioned virtual reference surface to the deepest part of the sipe, and use the average value as the depth (mm) of the sipe.
又,在本實施形態,複數個細縫部12的各細縫部在俯視觀看,與衛生棉2的寬幅方向Dw朝向平行的方向延伸。複數個細縫部若朝這樣的方向延伸,則吸收體容易朝衛生棉2的長方向DL彎曲,在折線區域5容易折疊。
In addition, in this embodiment, each of the sipes of the plurality of
如圖3所示,本實施形態中,複數個細縫部12在俯視觀看跨吸收體9及被覆薄片10的大致全面被配置呈交錯狀。又,複數個細縫部12在俯視觀看在一細縫部的延長線上其他的細縫部12不連續地延伸,亦即,間歇性地被配置在吸收體9的寬幅方向上。若如此配置複數個細縫部,在吸收體細縫部12不存在的剛性高的區域因為沒有連續被形成在衛生棉2的長方向DL上,所以衛生
棉2更容易變形,可讓衛生棉2的穿用感提昇。又,這樣的效果不限於上述的交錯狀的配置形態,例如,能將複數個細縫部配置呈鄰接於衛生棉2的長方向DL的細縫部彼此在前述長方向DL具有常為重疊的部分。
As shown in FIG. 3, in this embodiment, the
又,本發明的吸收性物品中,複數個細縫部的配置形態不限於上述的交錯狀,在不會損及吸收體的變形容易性、作為吸收體的剛性的範圍內,可採用任意的配置形態。 In addition, in the absorbent article of the present invention, the arrangement of the plurality of slits is not limited to the above-mentioned staggered shape, and any arrangement can be adopted within a range that does not impair the ease of deformation of the absorbent body and the rigidity of the absorbent body. form.
關於形成複數個細縫部的手段並沒有特別的限制,可使用任意的切斷手段。例如,複數個細縫部,是如上述藉由任意的搬送手段邊搬送接合後的吸收體及被覆薄片,邊從被覆薄片的上方藉由壓抵被設在旋轉的切斷輥的周面上的複數個切斷刀而可形成。此外,藉由調節切斷輥的切斷刀與搬送手段之間的間距,可以不貫穿吸收體地形成細縫部。 There are no particular restrictions on the means for forming a plurality of slits, and any cutting means can be used. For example, a plurality of slits are provided on the peripheral surface of the rotating cutting roller while conveying the joined absorbent body and the covering sheet by arbitrary conveying means as described above, and pressing against the covering sheet from above. It can be formed by multiple cutting knives. In addition, by adjusting the distance between the cutting blade of the cutting roller and the conveying means, the slit portion can be formed without penetrating the absorber.
以形成前述細縫部的方法來說,可舉包含:藉由任意的搬送手段搬送一體化後的被覆薄片及吸收體的工程(a);藉由邊搬送前述被覆薄片及吸收體,邊從前述被覆薄片的上方壓抵複數個切斷刀,貫穿前述被覆薄片形成被形成到前述吸收體的厚度方向DT的中途部分的複數個細縫部的工程(b);以及從前述被覆薄片及吸收體去除前述切斷刀的工程(c)的方法。 As a method of forming the aforementioned sipes, there can be mentioned: the process (a) of conveying the integrated covering sheet and absorbent body by any conveying means; by conveying the covering sheet and absorbent body while moving from the aforementioned The process (b) of forming a plurality of slits formed in the middle part of the thickness direction D T of the absorbent body through the covering sheet by pressing a plurality of cutting blades against the upper part of the covering sheet; and from the covering sheet and the absorbent body Process (c) method of removing the aforementioned cutting knife.
該方法,是在前述工程(b),雖形成有前述複數個細縫部,可是此時,藉由前述切斷刀的按壓力,壓 榨前述細縫部的底部與前述搬送手段之間的部分,能形成高密度部,所以,可精度佳地實現以前述高密度部作為起點的吸收體的折疊,可提供穿用者舒適的安裝感。 In this method, in the aforementioned process (b), although the aforementioned plural slits are formed, at this time, the pressing force of the aforementioned cutting knife is used to press The part between the bottom of the sipe part and the conveying means can form a high-density part. Therefore, the absorbent body can be folded with the high-density part as the starting point with high accuracy, and it can provide the wearer with a comfortable fitting feeling. .
此外,高密度部是如後述,為細縫部與在吸收體的厚度方向不重複的部分的相較下纖維密度高的部分。又,纖維密度的比較,是例如藉由電子顯微鏡觀察測量對象部位,藉由比較該部位中的纖維間空隙的最大徑的方式來進行。 In addition, the high-density portion is a portion having a higher fiber density than a portion that does not overlap in the thickness direction of the absorbent body with the slit portion as described later. In addition, the comparison of the fiber density is performed, for example, by observing the measurement target part with an electron microscope and comparing the maximum diameter of the inter-fiber voids in the part.
本發明的吸收性物品中,細縫部的延伸方向不限於和吸收性物品的寬幅方向DW平行的方向,並包含相對於吸收性物品的寬幅方向DW實質上平行的方向。本說明書中,「相對於吸收性物品的寬幅方向DW實質上平行的方向」,是指:將複數個細縫部形成在這樣的方向上延伸時,吸收體及被覆薄片作用容易朝具有前述細縫部的面側折疊(亦即,成為容易朝具有細縫部的面側谷折)的方向,例如,相對於吸收性物品的寬幅方向DW理想是形成0°以上不足30°的角度的方向,更理想是形成0°以上不足20°的角度的方向,更為理想是形成0°以上不足10°的角度的方向。此外,在本說明書中,「相對於吸收性物品的寬幅方向DW形成0°以上不足30°的角度」是指:由平行於吸收性物品的寬幅方向DW的直線與細縫部相交所形成的角度中的最小的角度在0°以上不足30°的角度。又,細縫部的延伸方向、與吸收性物品的寬幅方向DW形成的角度若在30°以上,形成細縫部的時候,因為在吸收體內容 易切斷配向於吸收性物品的寬幅方向DW的纖維,所以會有吸收體的寬幅方向中的剛性下降的虞慮。而相對於此,細縫部的延伸方向相對於吸收性物品的寬邊方向DW實質上若為平行的方向,由於吸收體及被覆薄片容易朝具有前述細縫部的面側折疊,所以,可讓吸收體及被覆薄片容易沿著裝用者的身體形狀變形,並且可防止吸收體中的紙漿等從前述細縫部露出的情形。 In the absorbent article of the present invention, the direction in which the slits extend is not limited to a direction parallel to the width direction D W of the absorbent article, and includes a direction substantially parallel to the width direction D W of the absorbent article. In this specification, the "direction that is substantially parallel to the width direction D W of the absorbent article" means that when a plurality of slits are formed and extended in such a direction, the absorbent body and the covering sheet are likely to function as the aforementioned The surface side of the slit portion is folded (that is, it becomes easy to fold toward the surface side with the slit portion). For example, it is desirable to form an angle of 0° or more and less than 30° with respect to the width direction D W of the absorbent article The direction is more preferably a direction that forms an angle of 0° or more and less than 20°, and more preferably a direction that forms an angle of 0° or more and less than 10°. In addition, in this specification, "an angle of 0° or more and less than 30° with respect to the width direction D W of the absorbent article" means that a straight line parallel to the width direction D W of the absorbent article intersects the slit The smallest angle among the formed angles is 0° or more and less than 30°. In addition, if the extending direction of the slit portion and the angle formed by the width direction D W of the absorbent article are greater than 30°, when the slit portion is formed, it is easy to cut in the absorbent body aligned with the width direction D of the absorbent article Because of W fibers, there is a concern that the rigidity in the width direction of the absorber may decrease. On the other hand, if the extending direction of the slit portion is substantially parallel to the widthwise direction D W of the absorbent article, since the absorbent body and the covering sheet are easily folded toward the side having the slit portion, it is possible to allow The absorbent body and the covering sheet are easily deformed along the body shape of the wearer, and it is possible to prevent the pulp and the like in the absorbent body from being exposed from the aforementioned slits.
又,如圖4與圖5所示,本實施形態中,吸收體9進一步在吸收體9的厚度方向與細縫部12對應的位置具備從肌膚非對置面被形成到厚度方向的中途的凹部14。本發明的吸收性物品中,凹部的構造,是只要不損害吸收體的折疊容易性則沒有特別被限制,可是凹部的寬幅方向的長度從順著身體形狀的變形的容易性等的點,是例如在3mm~60mm,理想是在5mm~20mm。又,凹部的長方向中的長度也雖沒有特別的限制,可是例如是在0.1mm~5mm,理想是在0.5mm~2mm。凹部的寬幅若在這樣的範圍內,容易作為吸收體彎折時的起點發揮功能。
In addition, as shown in FIGS. 4 and 5, in this embodiment, the
本發明的吸收性物品中,凹部的深度雖沒有特別限制,可是從吸收體的折疊容易等的點,例如是在0.05mm~5.0mm,更理想是在0.1mm~3.0mm。此外,本說明書中,凹部的深度,是指與具有吸收體9的細縫部的面相反側的面、和凹部的最深部之間的距離,且可藉由與上述的細縫部的深度同樣的測量方法求取。亦即,在上述的細縫部的深度的測量方法,測量前述假想底面到凹部的
最深部的距離(mm),並將針對任意10個凹部實施後的上述距離的測量值的平均值作為凹部的深度(mm)。
In the absorbent article of the present invention, the depth of the recess is not particularly limited, but from the point of ease of folding of the absorbent body, it is, for example, 0.05 mm to 5.0 mm, more preferably 0.1 mm to 3.0 mm. In addition, in this specification, the depth of the recess refers to the distance between the surface opposite to the surface having the slit portion of the
又,衛生棉2中,細縫部12的深度比凹部14的深度更深。因為將細縫部12的深度設的比凹部14的深度更深,而形成將吸收體9朝具有細縫部12的面側彎折,所以可藉由前述細縫部防止吸收體9中的紙漿等露出的情況,其結果,可讓作為吸收體的耐久性提昇。
In addition, in the
本發明的吸收性物品中,俯視觀看中的凹部的形狀雖沒有特別的限制,可是與細縫部12具有實質上同一形狀為理想。細縫部與凹部在俯視觀看若具有實質上同一形狀,可以細縫部與凹部之間的部分作為起點精度佳地折疊吸收體。此外,本說明書中,實質上同一形狀,是指各形狀為同一種類的形狀,且各形狀的中心線彼此重複的形狀。
In the absorbent article of the present invention, the shape of the concave portion in a plan view is not particularly limited, but it is desirable that it has substantially the same shape as the
本發明的第1實施形態的衛生棉2中的凹部,是例如藉由壓花等的壓榨手段可容易形成。若藉由壓花等的壓榨手段形成前述凹部,在吸收體9的厚度方向,壓榨沒有貫穿的細縫部12的底部與凹部14之間的部分而高密度化,因為在該高密度部15與其周邊部分之間剛性差產生,所以該高密度部15成為吸收體9的折疊的起點,並且容易讓吸收體9回復平面形狀。又,藉由使細縫部12的底部與凹部14之間的部分高密度化,因此可強化吸收體9的具有細縫部12的區域,所以可讓作為吸收體的耐久性提昇。
The recesses in the
又,也可將前述壓榨手段兼用作為上述的細縫部12的形成手段。亦即,凹部14可與細縫部12同時形成。亦即,在形成前述的細縫部12的工程(前述工程(b)),藉由前述切斷刀的按壓力,壓榨細縫部12的底部與前述搬送手段之間的部分,而形成高密度部15的同時,吸收體9以前述切斷刀的抵接點(亦即,細縫部12的底部)為中心變形成朝下側凸。而且,如此變形後的吸收體9,在前述工程(c),若去除前述切斷刀的按壓力,雖藉由構成吸收體9的纖維的彈性力復原到原來的形狀,可是細縫部12的底部與前述搬送手段之間的高密度部15被壓榨而不會復原,因而維持該部分鄰接於細縫部12的底部的狀態,所以,以該部分為中心的凹部14被形成在吸收體9的具有前述搬送手段側的面(亦即,與具有細縫部12的面相反側的面)。
In addition, the aforementioned squeezing means may also be used as the aforementioned means for forming the
根據這樣的方法,因為細縫部12與凹部14在吸收體9的厚度方向對應的位置,形成在俯視觀看實質上具有同一形狀,所以可精度佳地實現以細縫部12的底部與凹部14之間的部分作為起點的吸收體的折疊,並可提供裝用者舒適的安裝感。又,因為在細縫部12的底部與凹部14之間形成有高密度部15,所以,可獲得與使用上述的壓花等所為的壓榨手段時同樣的效果。
According to this method, since the positions corresponding to the
接著,一面參照圖面一面針對本發明的第1實施形態的衛生棉2與包裝薄片3一起被折疊的形態進行說明。圖6,是本發明的第1實施形態的衛生棉2與包裝
薄片3一起在一折線區域5被折疊的狀態的立體圖,圖7,是本發明的第1實施形態的衛生棉2與包裝薄片3一起在全折線區域5被折疊的狀態的立體圖。如圖6所示,一折線區域5,是在其他的折線區域折疊衛生棉2與包裝薄片3時的長方向端部16沒有重複的位置被形成。在這樣的位置形成折線區域5,而如圖7所示,即使在全折線區域5折疊衛生棉2與包裝薄片3,先被折疊的長方向端部16在折線區域5內不會有再次被捲起的情況,被形成的個包裝體1也不體積變大。
Next, the state in which the
圖8,是本發明的第1實施形態的個包裝體1在一折線區域5被折疊到中途的狀態中的部分剖視圖。個包裝體1在折線區域5被折疊時,若肌膚對置面的表面薄片7彼此形成的角度θ減少的話,表面薄片7在折線區域5開始發生與吸收體9的層內剝離,而稍微隆起。而且,肌膚對置面的表面薄片7彼此接觸,若在折線區域5附近施加壓力的話,在隆起的表面薄片7產生破壞。如此,表面薄片7,是在折疊衛生棉2的時候藉由產生前述隆起部分,阻礙衛生棉2的折疊容易性,而折疊衛生棉2之後,藉由前述隆起部分的破壞保持折疊形狀。同樣的現象也可能在裏面薄片8、包裝薄片3等產生。
Fig. 8 is a partial cross-sectional view of the
另一方面,衛生棉2的吸收體9具備細縫部12,細縫部12至少在折線區域5內,藉由在寬幅方向且貫穿被覆薄片10而被形成到吸收體9的厚度方向的中途部分,在折線區域5的長方向中設有細縫部12的部分與
這以外的部分產生剛性差,折疊成個包裝形態時,細縫部12成為彎折起點,而容易形成折疊形狀。又,因為細縫部12切入到吸收體9的肌膚對置面,所以,前述表面薄片7中的隆起不會產生,衛生棉2的折疊容易性不會被阻礙。
On the other hand, the
再者,吸收體9,由於是至少與細縫部12在吸收體的厚度方向重複的位置具備高密度部15,所以,在該高密度部15與其周邊部分之間剛性差產生,折疊成個包裝形態時,高密度部15成為彎折起點,容易形成折疊形狀。又,前述高密度部15,因為是提高細縫部12與在吸收體9的厚度方向重複的位置中的部分的剛性,所以,回復到平面形狀的力(復原力)作用,而作為使吸收體9回復到平面形狀時的力學要素發揮功能。
Furthermore, the
又,含高密度部15的區域,是從凹部14的外周面弧狀被形成到吸收體9的厚度方向中途。含高密度部15的區域若這樣被形成的話,折疊吸收體9的時候,作用使含高密度部15的區域、U字型彈簧朝向與彎曲方向相反向延伸,吸收體9回復到平面形狀的力(復原力)進一步作用。
In addition, the region including the high-
此外,高密度部15在吸收體9的厚度方向被形成在沒有貫穿細縫部12的底部與凹部14之間的部分,含高密度部15的區域,是包含從凹部14的外周面弧狀被形成到吸收體9的厚度方向的中途的高密度部15以外的中密度部。又,吸收體9中含高密度部15的區域以外的區域是
低密度部。
In addition, the high-
再者,本實施形態中,雖說明吸收體具備凹部14的構造,可是在其他的實施形態,吸收體不具備凹部14,僅在細縫部與在厚度方向重疊的部分吸收體的基量高,藉由均勻按壓該吸收體形成有含高密度部的區域。
In addition, in this embodiment, although the structure in which the absorber is provided with the recessed
本發明中的細縫部的深度,是如上述為吸收體9的厚度的一半以下,或也可在70%以下。細縫部12若如此被形成時,由於沒有形成細縫部12的部分佔吸收體9的厚度的一半以上、或30%以上,所以,充分作用回復到平面形狀的力(復原力),能進一步改善折線區域5中的衛生棉2的安裝感。
The depth of the slit portion in the present invention is half or less of the thickness of the
本發明中的折線區域也可在吸收性物品與包裝薄片重疊的位置形成有複數個。此時,細縫部在各個折線區域內至少形成有1個以上為理想。若如此形成細縫部,吸收體在任一折線區域也容易折疊。 The folding line area in the present invention may be formed in plural at positions where the absorbent article and the packaging sheet overlap. At this time, it is desirable that at least one slit part is formed in each fold line area. If the slits are formed in this way, the absorbent body is easily folded in any folding line area.
又,如上述,細縫部也可形成其他的細縫部在一細縫部的寬幅方向的延長線上間歇性地延伸。如此形成細縫部,由於是在折線區域其他的細縫部不連續地在一細縫部的延長線上延伸,所以,非細縫部存在於寬幅方向中的同一線上,而比一細縫部在寬幅方向上連續延伸的情況更能保持吸收體的剛性。又,在吸收體的寬幅方向留下沒有形成細縫部的部分,可發揮從折疊吸收性物品的狀態被展開時的復原力。 In addition, as described above, the slit portion may be formed as another slit portion that intermittently extends on an extension line in the width direction of the slit portion. The sipes are formed in this way, because the other sipes in the fold line area discontinuously extend on the extension line of a sipe, so the non-slits are on the same line in the width direction, but are in the width direction than a sipe. The continuous extension of the upper part can maintain the rigidity of the absorber. In addition, the portion where the slit is not formed is left in the width direction of the absorbent body, and the restoring force when the absorbent article is unfolded from the folded state can be exerted.
如圖8所示,在裏面薄片8在和包裝薄片3
對置的面(亦即,肌膚非對置面、或著衣抵接面),形成有將衛生棉2不能移動地安裝在內褲等的裝用者的衣服用的固定部13、13。該固定部13、13,是例如在裏面薄片8的著衣抵接面的預定位置塗布熱熔系接著劑而被形成。
As shown in Figure 8, the sheet 8 is inside and the
固定部13、13,是衛生棉2的著衣抵接面,且被形成在折線區域5與細縫部12重疊的區域以外的區域。固定部13、13被形成在這樣的區域,所以折疊衛生棉2時,由於在衛生棉2的著衣抵接面的折線區域5固定部13、13並不存在,所以不會阻礙吸收體9回復到平面形狀的力(復原力)。在衛生棉2的著衣抵接面的折線區域5固定部13、13若存在,在折疊衛生棉2的狀態下固定部13、13被延展,而可維持其狀態。而且,隨著延展固定部13、13,在表面薄片7與裏面薄片8之間產生路徑差,裏面薄片8也容易維持被折疊的狀態,而使衛生棉2不易回復到平面形狀,結果來說,衛生棉2的安裝感變差。
The fixing
又,如圖2所示,本發明的第1實施形態的衛生棉2,在前述吸收體9的寬幅方向DW中的兩緣部,前述細縫部12並不存在。在這樣的兩緣部細縫部並不存在,因此吸收體9在該兩緣部可確保預定的強度,所以即使在衛生棉2的寬幅方向DW的兩緣部與裝用者的腿圍之間摩擦等產生,吸收體也不易破裂,而且,在吸收體的寬幅方向端部留下沒有形成細縫部12的部分,而可發揮衛生棉2從被折疊的狀態被展開時的復原力。
In addition, as shown in Fig. 2, in the
本發明的吸收性物品,從防止吸收體與被覆薄片分離的觀點,雖藉由利用壓花等對吸收體與被覆薄片進行壓榨而一體化,可形成複數個壓榨部,可是,根據該複數個壓榨部的數量、大小,會有吸收體的剛性變太高,吸收性物品不易仿效裝用者的身體形狀變形的顧慮。因此,在吸收體及被覆薄片形成複數個壓榨部時,構成前述壓榨部的至少一部分與細縫部重疊為理想。因為在壓榨部的至少一部分形成細縫部,可讓吸收體的剛性下降,所以,可在一定的範圍內抑制複數個壓榨部所致的吸收體過度高剛性化的情況,就吸收性物品來說可獲得適合的貼合性。 In the absorbent article of the present invention, from the viewpoint of preventing separation of the absorbent body and the covering sheet, although the absorbent body and the covering sheet are squeezed and integrated by embossing or the like, a plurality of press parts can be formed, but according to the plurality of The number and size of the squeezing part may cause the rigidity of the absorbent body to become too high, and the absorbent article may not be easily deformed following the shape of the wearer's body. Therefore, when the absorbent body and the covering sheet form a plurality of press sections, it is desirable that at least a part of the press section is overlapped with the slit section. Since the slits are formed in at least a part of the press section, the rigidity of the absorber can be reduced. Therefore, it is possible to suppress the excessive increase in rigidity of the absorber caused by the plural press sections within a certain range. In the case of absorbent articles A suitable fit can be obtained.
又,本發明的第1實施形態的衛生棉2,是如前述形成壓榨溝11與折線區域5內的至少一個細縫部12在平面方向正交。如此形成壓榨溝11強化長方向中的衛生棉2的剛性,使平面形狀衛生棉2回復到平面形狀時可充分作用回復到平面形狀的力(復原力),而可進一步改善折線區域5中的衛生棉2的安裝感。
In addition, in the
又,本發明的吸收性物品中,複數個細縫部也可僅被配置在吸收體及被覆薄片的一部分的區域,此時,複數個細縫部也可僅被配置在折線區域、想讓剛性降低之處。例如,本發明的吸收性物品,是為了讓裝用者的排泄口抵接的排泄口抵接區域的吸收性能提昇,雖可較周邊區域調配更多該排泄口抵接區域的吸收體中的紙漿量,可是,吸收體中的紙漿量若變多,因為排泄口抵接區域的 剛性變高,所以,在該排泄口抵接區域配置複數個細縫部,既可讓吸收性物品的吸收性能提昇,並可抑制吸收體的高剛性化。又,位在吸收性物品的長方向的兩端部側的前方區域及後方區域,因為是對應裝用者的身體形狀的曲率大的部分的區域,所以,在前述前方區域或前述後方區域的至少一方的區域配置複數個細縫部,對應裝用者的身體形狀的曲率大的部分的區域的剛性降低,可讓吸收性物品對裝用者的身體形狀的貼合性進一步提昇。 In addition, in the absorbent article of the present invention, the plurality of slits may be arranged only in a part of the absorbent body and the covering sheet. In this case, the plurality of slits may be arranged only in the fold line area to reduce rigidity. Place. For example, the absorbent article of the present invention is designed to improve the absorption performance of the excretion opening contact area of the wearer's excretion opening. Although more of the excretion opening contact area of the absorbent body can be deployed than the peripheral area The amount of pulp, however, if the amount of pulp in the absorber increases, it is because the area where the excretion abuts Since the rigidity becomes higher, arranging a plurality of slits in the abutment area of the excretion opening can improve the absorption performance of the absorbent article and suppress the increase in rigidity of the absorbent body. In addition, the front area and the back area located at the both ends of the absorbent article in the longitudinal direction are the areas corresponding to the curvature of the wearer’s body shape. Therefore, the areas in the front area or the back area A plurality of slits are arranged in at least one area, and the rigidity of the area corresponding to the portion with a large curvature of the wearer's body shape is reduced, and the fit of the absorbent article to the wearer's body shape can be further improved.
圖9,是本發明的第2實施形態的個包裝體1’的吸收體9’的俯視圖。該實施形態中的吸收體9’除了細縫部12’所形成的態樣以外,是具有與上述的實施形態同樣的構成。該實施形態中,細縫部12’在折線區域內設置1個以上具有朝向吸收體9’的長方向端部17的凸形狀。
Fig. 9 is a plan view of the absorber 9'of the individual package 1'according to the second embodiment of the present invention. The absorber 9'in this embodiment has the same structure as the above-mentioned embodiment except for the aspect in which the slit portion 12' is formed. In this embodiment, the slit portion 12' is provided with one or more convex shapes facing the
本實施形態中的細縫部12’,是只要被設在吸收體9’的寬幅方向DW中的兩緣部以外的區域,長度、曲率可適當變更。如此在兩緣部細縫部12’並不存在,是如上述因為在該兩緣部可確保預定的強度,所以即使在衛生棉2’的寬幅方向DW的兩緣部與裝用者的腿圍之間摩擦等產生,吸收體也不易破裂,而且,在吸收體的寬幅方向端部留下沒有形成細縫部12’的部分,而可發揮衛生棉2’從被折疊的狀態被展開時的復原力。 As long as the slit portion 12' in the present embodiment is provided in a region other than the two edge portions in the width direction DW of the absorber 9', the length and curvature can be changed as appropriate. In this way, the sipes 12' do not exist at the two edge portions. As described above, because the predetermined strength can be ensured at the two edge portions, even the two edges of the sanitary napkin 2'in the width direction D W and the wearer Friction between the legs, etc., the absorbent body is not easy to break, and at the end of the width direction of the absorbent body, the part where the slit portion 12' is not formed is left, and the sanitary napkin 2'can be unfolded from the folded state. Time resilience.
如此,藉由在衛生棉2’的寬幅方向上連續形 成彎曲細縫部12’的形狀,吸收體9’的折線將形成為連結細縫部12’的始點與終點的線、或形成在凸的部分地加以誘導,而可更容易折疊吸收體9’。 In this way, by continuously forming in the width direction of the sanitary napkin 2’ In the shape of a curved slit portion 12', the fold line of the absorbent body 9'will be formed as a line connecting the start and end points of the slit portion 12', or formed on a convex part to induce it, making it easier to fold the absorbent body 9' .
本發明的吸收性物品中,細縫部的俯視觀看中的形狀,不限於上述的實施形態,在不會損及吸收體的變形容易性、作為吸收體的強度的範圍內,可採用任意的形狀。以這類的細縫部的形狀來說,例如可舉:V字形、波形、鋸齒形、圓形、多角形等。 In the absorbent article of the present invention, the shape of the slit portion in a plan view is not limited to the above-mentioned embodiment, and any shape can be adopted within the range that does not impair the ease of deformation of the absorbent body and the strength as the absorbent body . As for the shape of such a slit portion, for example, a V-shape, a wave shape, a sawtooth shape, a circular shape, and a polygonal shape can be mentioned.
又,第1及第2實施形態中,雖說明在肌膚對置面形成有細縫部12、12’的情況,可是根據本發明的其他的實施形態的個包裝體中的細縫部,是被形成在肌膚非對置面。此時,在吸收體的折線區域,在設有細縫部的部分與這以外的部分產生剛性差,細縫部成為彎折起點。又,藉由在肌膚非對置面形成細縫部,可吸收折疊吸收性物品時產生的路徑差。藉由該等的作用,將吸收性物品折疊成個包裝形態時,容易形成折疊形狀。
Also, in the first and second embodiments, although the case where the
本發明,是除了上述的各實施形態的生理用的衛生棉之外,例如可適用在衛生護墊、失禁墊片等的各式各樣的吸收性物品。又,本發明的吸收性物品不會被上述的實施形態所限制,在不脫離本發明的目的、宗旨的範圍內可適當變更。 The present invention is applicable to various absorbent articles such as sanitary pads and incontinence pads in addition to the sanitary napkins of the above-mentioned respective embodiments. In addition, the absorbent article of the present invention is not limited by the above-mentioned embodiment, and can be appropriately modified within a range that does not deviate from the purpose and spirit of the present invention.
