Description
本發明係關於紙尿布、尿液吸收墊等的吸收性物品。 The present invention relates to absorbent articles such as paper diapers and urine absorbent pads.
作為以往的紙尿布、尿液吸收墊等的吸收性物品,在專利文獻1所揭示的一種吸收性物品,其藉由朝縱方向延伸的3片以上的薄片材構成配置於吸收芯材的肌膚面側之內側薄片構件。此吸收性物品係位於橫方向的外方側的薄片材之前述橫方向的內方側的緣部從肌膚面側重疊於位於前述橫方向的內方側的相鄰之薄片材的前述橫方向的外方側的緣部來構成的。 As an absorbent article such as a conventional paper diaper, urine absorbent pad, etc., an absorbent article disclosed in Patent Document 1 is composed of three or more sheets extending in the longitudinal direction to constitute the skin disposed on the absorbent core Inner sheet member on the face side. This absorbent article is an edge portion of a sheet material located on the outer side in the transverse direction, and an edge portion on the inner side in the aforementioned transverse direction overlaps from the skin surface side in the aforementioned transverse direction to the adjacent sheet material located on the inner side in the transverse direction. The outer side of the edge is composed.
此專利文獻1所揭示之吸收性物品為利用以3片以上的薄片材構成前述內側薄片構件所構成,以各薄片材的緣部形成2個以上朝縱方向延伸之階差,藉以促進已被排出的尿液朝縱方向擴散。 The absorbent article disclosed in this Patent Document 1 is formed by using three or more sheets to constitute the inner sheet member, and the edges of each sheet form two or more steps extending in the longitudinal direction to promote The excreted urine spreads in the longitudinal direction.
又,在專利文獻2揭示有一種吸收性物品,其在設置於表面薄片的寬度方向之兩端部的左右一對皺褶薄片間,具備前述表面薄片的一部分突出而形成之左右一
對突出部。在此吸收性物品,前述表面薄片是由從吸收性物品的寬度方向之一端連續至另一端的單一薄片材所構成,前述突出部係藉由將此單一薄片材部分地折疊所形成。
In addition,
此專利文獻2所揭示的吸收性物品為藉由在
表面薄片上形成前述左右一對突出部,可減弱被排出的體液流出之強度,讓該體液朝長度方向擴散。

在如專利文獻1這種藉由3片以上的薄片材構成內側薄片構件(表面薄片構件)之吸收性物品,一般是各薄片材在薄片材彼此重疊的部位以熱熔膠型接著劑(HMA)的全面塗佈加以接合。但,當各薄片材藉由這種HMA的全面塗佈所接合時,即使已被排出的尿液等的體液到達前述重疊部分,接合部的HMA會成為前述體液吸入的阻礙,因此,會有不易吸入前述體液之虞產生。 In an absorbent article in which an inner sheet member (surface sheet member) is composed of three or more sheets as in Patent Document 1, generally, each sheet is coated with a hot-melt adhesive (HMA) at a position where the sheets overlap each other ) For full-scale coating. However, when the sheet materials are joined by such a full-scale coating of HMA, even if body fluids such as urine that has been discharged reach the overlapping portion, the HMA at the joining portion becomes an obstacle to the inhalation of the body fluid. It is not easy to inhale the aforementioned body fluid.
又,如專利文獻2這種將表面薄片部分地折疊而形成突出部之吸收性物品,當已被排出的尿液等的體
液到達前述突出部時,由於前述突出部為將由單一的薄片材所構成的表面薄片予以部分地折疊而形成的,故,會有前述體液被吸入至此突出部的內部,從前述突出部的下側朝吸收性物品的寬度方向滲出,前述體液變得不易朝吸收性物品的長度方向擴散之虞。又,即使被吸入到前述突出部的內部之體液未自前述突出部的下側滲出而殘留在前述突出部的內部,也會有因壓力的負荷等,前述體液朝突出部外部的肌膚面側流出(亦即,回流)。
In addition, as in the case of an absorbent article such as
本發明係關於吸收性物品,其目的在於提供 一種吸收性物品,其能夠使已被排出的尿液等的體液良好地朝表面薄片上的長度方向擴散,並且已朝前述長度方向擴散的體液之吸收變得良好,並且前述體液的逆流少之吸收性物品。 The present invention relates to absorbent articles, the purpose of which is to provide An absorbent article capable of allowing body fluids such as discharged urine to diffuse well in the longitudinal direction on the surface sheet, and absorption of body fluids diffused in the longitudinal direction becomes good, and the backflow of the body fluid is less Absorbent articles.
本發明係一種吸收性物品,係具有長度方向及寬度方向,並具備配置於肌膚面側的透液性之表面構件和配置於該表面構件的衣服側之吸收體,其特徵為:前述表面構件具備:配置於前述吸收性物品的長軸線上,且朝前述長度方向延伸之中央薄片構件;及配置於該中央薄片構件的前述長度方向之兩側部,且朝前述吸收性物品的長度方向延伸之一對側部薄片構件,前述表面構件具有一對第1重複部,該一對第1重複部包含有藉由從肌膚面側將前述一對側部薄片構件重疊於 前述中央薄片構件所形成的重複部分且朝前述長度方向延伸,前述一對第1重複部分別具有:將前述中央薄片構件及前述側部薄片構件予以接合且朝前述長度方向延伸的第1接合部;及沿著前述第1接合部且朝前述長軸線方向突出之前述側部薄片構件的第1自由緣部。 The present invention is an absorbent article having a longitudinal direction and a width direction, and having a liquid-permeable surface member arranged on the skin surface side and an absorber arranged on the garment side of the surface member, characterized in that the surface member Comprising: a central sheet member arranged on the long axis of the absorbent article and extending in the longitudinal direction; and a central sheet member arranged on both sides of the longitudinal direction of the central sheet member and extending in the longitudinal direction of the absorbent article A pair of side sheet members, the surface member having a pair of first repeating parts, the pair of first repeating parts including by overlapping the pair of side sheet members from the skin surface side The repeating portion formed by the central sheet member extends in the longitudinal direction, and the pair of first repeating portions each have a first joint portion that joins the central sheet member and the side sheet member and extends in the longitudinal direction ; And the first free edge portion of the side sheet member that protrudes in the long axis direction along the first joint portion.
若依據本發明,前述側部薄片構件的第1自由緣部即使在將吸收性物品展開的狀態亦可起立而形成起立部,但將吸收性物品朝長度方向內側折彎時更容易形成起立部,藉由這樣的起立部,能夠使已被排出的體液朝表面薄片上的長度方向良好地擴散,並且擴散於前述長度方向上的體液之吸入變得良好,並可使前述體液的逆流變少。 According to the present invention, the first free edge portion of the side sheet member can stand up to form an upright portion even when the absorbent article is unfolded, but it is easier to form the upright section when the absorbent article is bent inward in the longitudinal direction With such a standing portion, the discharged body fluid can be diffused well in the longitudinal direction on the surface sheet, and the absorption of the body fluid diffused in the longitudinal direction becomes good, and the backflow of the body fluid can be reduced .

又,本發明的中央薄片構件配置於吸收性物 品的前述中央區域內為佳。當中央薄片構件配置於前述中央區域內時,已被排出的尿液等的體液經由前述中央薄片構件變得容易導入到配置在前述表面構件的衣服側(亦即,穿用者的肌膚面側之相反側)的前述中央區域內之吸收體,其結果,前述體液變得不易到達吸收性物品的寬度方向W之端部,因此,能夠減低來自於吸收性物品的寬度方向W之體液洩漏(亦即側漏)。 Moreover, the center sheet member of this invention is arrange|positioned in an absorbent material The product is preferably in the aforementioned central area. When the central sheet member is disposed in the central region, body fluids such as urine that has been discharged are easily introduced through the central sheet member to the clothing side (that is, the wearer's skin side) disposed on the surface member (The opposite side) of the absorbent body in the central region, as a result, the body fluid becomes less likely to reach the end of the absorbent article in the width direction W, so that the leakage of body fluid from the absorbent article in the width direction W can be reduced ( (That is, side leakage).
在本實施形態,側部薄片構件22、23若為具
有透液性的薄片構件則未特別限制,能夠使用與中央薄片
構件21相同的薄片構件。作為本發明的側部薄片構件之理想的薄片構件,為例如基重為10g/m2~30g/m2之不織布。但,如後述般,由於側部薄片構件之寬度方向W的長軸線側的端緣成為自由緣部,該自由緣部起立而形成起立部,故需要考量已被排出的體液之朝長度方向L的擴散性、穿用者的肌膚觸感等,選定基重、厚度、構造、材質等。
In this embodiment, the
又,在本實施形態,配置於吸收性物品1的
中央區域14內之中央薄片構件21的透液性較側部薄片構件22、23高為佳。在本發明,當中央薄片構件的透液性較側部薄片構件高時,能夠使藉由後述的第1自由緣部所形成之起立部之體液遮斷停止效果變高,因此,促進配置於前述表面構件的衣服側之前述中央區域內的吸收體之體液吸收,可更有效地防止前述體液橫向洩漏。
In addition, in this embodiment, the

In the present invention, the absorption system is arranged on the clothing of the surface member
On the side, it absorbs body fluids such as urine and water contained in feces that have passed through the surface member. In this embodiment, the
作為這些的吸收芯材31、32,若為具有可將
已被排出的尿液等的體液予以吸收並保持的功能者,則未特別限定,能夠使用以往以來紙尿布等所採用之任意的吸收要素。一般,當考量吸水性、裝設時的舒適性等,吸收芯材係蓬鬆度高、不易形狀崩潰、且化學性刺激少的芯材
為佳。作為本發明的吸收芯材,可舉出例如藉由以透液性薄片所構成的纜芯繞包層覆蓋包含絨毛漿、紡黏不織布、氣流成網不織布、熱可塑性纖維等的纖維系材料和高吸收性聚合物(SAP)等的高分子吸收劑之吸收芯材要素者。
再者,前述吸收芯材要素可不包含高吸收性聚合物,例如亦可將以芯材繞包層僅覆蓋前述纖維系材料者作為前述吸收芯材來使用。又,作為前述芯材繞包層,可舉出例如基重為約10~約30g/m2程度的薄紙、透液性不織布、親水性不織布等的透液性薄片。
These
前述吸收芯材31、32的構造,未特別限制,
可採用任意構造者。本發明的吸收芯材可為相互同樣的構造,亦可為不同構造。在將這些吸收芯材作成相互不同的構造之情況,將其中一方的吸收芯材配置在當將吸收性物品展開的狀態之平面視角下之與吸收性物品的前述中央薄片構件相對應的區域內,並且將另一方的吸收芯材形成為較前述其中一方的吸收芯材在寬度方向W更長(亦即寬度廣)為佳。當作成這樣的結構時,吸收體之與前述中央薄片構件相對應的部分之厚度變厚,該部分的基重較其他部分的基重變大,因此,能夠使前述吸收體的吸收容量集中於與前述吸收性物品的前述中央薄片構件相對應之部分。其結果,藉由吸收體之與前述中央薄片構件相對應的部分之體液吸收量增大,使得前述體液橫向洩漏減少,因此,能夠減低因前述體液所造成之污染區域。
The structure of the aforementioned
又,從防止體液橫向洩漏等的觀點來看,亦可如圖1所示,在將吸收性物品1展開的狀態之平面視角下,將前述第1吸收芯材及第2吸收芯材中的至少其中一方之吸收芯材形成為葫蘆狀。 In addition, from the viewpoint of preventing lateral leakage of body fluids, etc., as shown in FIG. 1, in the plane viewing angle of the state where the absorbent article 1 is unfolded, the above-mentioned first absorbent core material and second absorbent core material At least one of the absorbent core materials is formed in a gourd shape.
再者,在本實施形態,吸收體3係具有以兩個吸收芯材31、32所形成之雙層構造,但本發明的吸收性物品不限於這種構造,亦可例如具有利用一個吸收芯材之單層構造,亦可為具有將3個以上的吸收芯材予以層積所構成之多層構造者。即使在具有這樣單層構造或多層構造之情況,亦與前述雙層構造同樣地,為了使吸收體之與前述中央薄片構件對應的部分之基重較其他部分的基重大,將前述吸收芯材之與前述中央薄片構件對應的部分之厚度及/或層數構成為較其他部分的厚度及/或層數大為佳。
Furthermore, in this embodiment, the
在本實施形態,背面構件4為配置於吸收體3的衣服側之不透液性薄片。作為構成本發明的背面構件之不透液性薄片,若為對尿液等的體液具有不透液性者則未特別限定,可採用以往以來作為紙尿布等的不透液性薄片所使用之任意的薄片材。此不透液性薄片不僅對尿液等的體液具有不透液性且具有通氣性為佳。作為這樣的不透液性薄片,可舉出例如基重為約15~約25g/m2程度的聚乙烯等之具有不透液性的合成樹脂薄膜、基量為約10~約30g/m2的SMS不織布及具有撥水性的合成纖維製不織布等的不織布與具有不透液性之合成樹脂薄膜的層積薄片等。

以下,進一步詳細地說明本實施形態之吸收性物品1的表面構件2之結構。
Hereinafter, the structure of the
如圖1及圖2所示,在本發明的吸收性物品1,前述中央薄片構件21係在該中央薄片構件21的長度方向L之兩側部,一對側部薄片構件22、23的長軸線C側之各側部分別從肌膚面側重疊。又,此中央薄片構件21與各側部薄片構件22、23重疊之各自的第1重複部A1
係為了在前述側部薄片構件22、23之長軸線C側的各側部之端緣側形成第1自由緣部22a、23a,而在與前述各側部的端緣分離之部位相互地接合。
As shown in FIGS. 1 and 2, in the absorbent article 1 of the present invention, the
圖3係前述吸收性物品1的第1重複部A1附
近E1之部分斜視圖,圖4係沿著前述吸收性物品1的第1重複部A1附近E2之寬度方向W之部分斷面圖。如圖3及圖4所示,各第1自由緣部22a、23a係當將吸收性物品1朝長度方向L內側折彎時等,以朝前述吸收性物品1的長軸線C側傾斜之樣態起立而形成起立部。又,此起立部係當尿液等的體液已被排出時,阻擋在表面構件2的肌膚面側上朝寬度方向W流來之前述體液,因此能夠有效地防止自前述吸收性物品1的寬度方向W之漏液(亦即橫向洩漏)。
3 is a perspective view of a portion of the absorbent article 1 near the first repeating portion A 1 near E 1 , FIG. 4 is a portion of the absorbent article 1 near the first repeating portion A 1 near the width direction W of the E 2 Face map. As shown in FIGS. 3 and 4, each of the first
又,由於在此起立部的基部,前述中央薄片
構件21與前述側部薄片構件22、23之第1接合部B1沿著吸收性物品1的長度方向L所形成,故,能夠使已被排出的體液沿著此第1接合部B1朝長度方向L擴散。且,由於以此起立部為境界,表面構件2的長軸線C側與長軸線C側相反側為非連續,故,前述體液朝寬度方向W之擴散被此非連續部分所抑制,其結果,可進一步促進前述體液朝長度方向L之擴散。又,當前述體液朝長度方向L擴散時,能夠使用配置於前述表面構件2的衣服側之吸收體3的寬廣範圍的面來吸收該體液,因此,可大幅地提升前述體液朝吸收體3之吸收速度。
In addition, since the base portion of the standing portion, the first bonding portion B 1 of the
又,藉由前述第1自由緣部22a、23a形成的
起立部是藉由一片的側部薄片構件22、23(理想為由不織布所構成之側部薄片構件22、23)所構成,因此,可抑制體液殘留於前述起立部,能夠減低體液附著於穿用者的肌膚,其結果,可保持穿用者的肌膚清潔。
Also, formed by the first
前述第1自由緣部22a、23a的寬度方向W之
長度WF若前述第1自由緣部22a、23a可發揮前述作用則未特別限定,可作成任意的寬度。例如,從已被排出之體液的遮斷停止效果、穿用者的穿用感等的觀點來看,本發明的第1自由緣部之寬度方向W的WF係在1mm~20mm的範圍內,理想為3mm~15mm的範圍內,更理想為4mm~10mm的範圍內。
The length W F of the first
又,前述第1自由緣部的寬度方向W之長度 WF係在吸收性物品的長度方向L之全長範圍呈一定為佳。當前述第1自由緣部的寬度方向W之長度WF在吸收性物品的長度方向L之全長範圍呈一定時,在已被排出的體液流動在表面構件的肌膚面側之面上時,利用以一定寬度的第1自由緣部所形成的起立部,能夠在前述吸收性物品的長度方向L之任一個位置,也可均等地將前述體液予以遮斷停止,因此能夠達到穩定的橫漏防止功能。 The length W F of the first free edge in the width direction W is preferably constant over the entire length of the absorbent article in the longitudinal direction L. When the length W F of the first free edge portion in the width direction W is constant over the entire length of the absorbent article in the longitudinal direction L, when the discharged body fluid flows on the surface of the surface member on the skin side, use The rising portion formed with the first free edge portion of a certain width can stop and stop the body fluid equally at any position in the longitudinal direction L of the absorbent article, so stable cross leakage prevention can be achieved Features.
在本發明,前述第1自由緣部的寬度方向W之長度WF、起立部的形態係可藉由中央薄片構件與側部薄片構件之第1重複部的第1接合部的形態等予以調節。例如,前述第1接合部係在將吸收性物品展開的狀態之平 面視角,可沿著長度方向L作成為直線狀。當將第1接合部作成為直線狀時,由於藉由前述第1自由緣部所形成的起立部之基部會成為直線狀,故,當已被排出的體液在表面構件的肌膚面側的面上流動時,將前述體液呈直線狀遮斷停止,在吸收性物品的長度方向L可在寬度方向W的相同位置停住前述體液,可更有效地抑制前述體液橫向洩漏。且,直線狀的第1接合部亦有可使被該接合部所遮斷停止的體液容易朝長度方向L圓滑地擴散之優點。 In the present invention, the length W F of the width direction W of the first free edge portion and the shape of the standing portion can be adjusted by the shape of the first joining portion of the first repeating portion of the central sheet member and the side sheet member, etc. . For example, the first joint portion is a plane view angle in a state where the absorbent article is unfolded, and may be linear along the longitudinal direction L. When the first joint portion is linear, since the base of the standing portion formed by the first free edge portion becomes linear, when the body fluid that has been discharged is on the surface of the surface member on the skin side When flowing upward, the body fluid is blocked in a straight line and stopped, and the body fluid can be stopped at the same position in the width direction W in the longitudinal direction L of the absorbent article, and the lateral leakage of the body fluid can be more effectively suppressed. In addition, the linear first joint portion also has the advantage that the body fluid blocked and stopped by the joint portion can easily spread smoothly in the longitudinal direction L.
又,前述第1接合部可作成為在將吸收性物 品展開的狀態之平面視角,沿著長度方向L作成為波浪狀或將螺旋投影於平面上的形狀等之非直線狀。當將第1接合部作成為非直線狀時,由於以前述第1自由緣部所形成起立部的基部為非直線狀,故,當已被排出的體液流動在表面構件的肌膚面側之面上時,能夠讓將前述體液遮斷停止之寬度方向W的位置沿著前述吸收性物品的長度方向L不同,因此,既可抑制前述體液朝寬度方向W之擴散,又可使用配置於表面構件的衣服側之吸收體的寬廣範圍的面有效率地吸收前述體液。且,由於非直線狀的第1接合部係當前述第1自由緣部起立時,容易在起立部形成皺褶部分,因此,可謀求緩衝性、肌膚觸感等的改善。 In addition, the first joining portion may be used as an absorbent The plane viewing angle of the unfolded state of the product is non-linear along the longitudinal direction L such as a wavy shape or a shape with a spiral projected on a plane. When the first joining portion is made non-linear, since the base of the rising portion formed by the first free edge portion is non-linear, the discharged body fluid flows on the surface of the surface member on the skin side When going up, the position in the width direction W where the body fluid is blocked can be made different along the longitudinal direction L of the absorbent article. Therefore, the spread of the body fluid in the width direction W can be suppressed, and the surface member can be used The wide surface of the absorbent body on the garment side efficiently absorbs the aforementioned body fluids. In addition, since the first non-linear first joining portion is formed when the first free edge portion is raised, it is easy to form a wrinkled portion in the raised portion, and therefore, it is possible to improve cushioning properties, skin feel, and the like.
前述第1接合部B1之寬度方向W的長度WB 未特別限定,可作成任意的寬度。在本發明,第1接合部的寬度方向W之長度WB為例如1mm~10mm的範圍內,理想為1.5mm~6mm的範圍內、更理想為2mm~4mm的 範圍內。又,從已被排出的體液的遮斷停止效果、接合強度、前述體液的吸入容易度等的觀點來看,前述第1自由緣部的寬度方向之長度WF與前述第1接合部的寬度方向W之長度WB的比(WF/WB)為5/3以上為佳。 The length W B of the first joining portion B 1 in the width direction W is not particularly limited, and can be any width. In the present invention, the length W B of the first joining portion in the width direction W is, for example, in the range of 1 mm to 10 mm, preferably in the range of 1.5 mm to 6 mm, and more preferably in the range of 2 mm to 4 mm. In addition, from the viewpoint of the blocking stop effect of the discharged body fluid, the bonding strength, the ease of aspiration of the body fluid, etc., the width W F of the first free edge portion and the width of the first bonding portion The ratio of the length W B of the direction W (W F /W B ) is preferably 5/3 or more.
在本發明,形成第1接合部及後述的第2接 合部之接合手段未特別限定,能夠採用此技術領域中習知的任意手段,可舉出例如採用熱熔膠型接著劑(HMA)的接著劑、熱壓花等的熱熔融之手段等。從將已被排出的體液遮斷停止之效果、接合強度優良等之觀點來看,第1接合部及第2接合部的接著手段,理想為使用接著劑,特別理想為使用HMA。 In the present invention, the first joint portion and the second joint to be described later are formed The joining means of the joint is not particularly limited, and any means known in this technical field can be used, and examples thereof include hot melt adhesives such as adhesives using hot melt adhesives (HMA) and hot embossing. From the standpoints of the effect of stopping the discharged body fluid, the excellent bonding strength, and the like, the bonding means of the first bonding portion and the second bonding portion is preferably using an adhesive, and particularly preferably using HMA.
本發明的表面構件係如上述般,可適用以往 以來習知的任意手段加以製造,例如,可藉由在中央薄片構件的長度方向L之各側部的上面中之與前述各側部的端緣分離之部位,分別沿著長度方向L塗佈HMA等的接著劑,再將一對側部薄片構件的前述長軸線C側的側部重疊於該塗佈的接著劑上予以接合來加以製造。又,本發明的吸收性物品,除了前述表面構件的製造製程以外,能夠藉由以往以來習知的任意之製造製程加以製造,因此,不需要特殊的製造設備、複雜的製造製程,能夠容易進行製造。 The surface member of the present invention is as described above and can be applied to the conventional It can be manufactured by any means known from the past, for example, it can be applied along the longitudinal direction L by a portion separated from the edge of each of the side portions on the upper surface of each side portion of the central sheet member in the longitudinal direction L Adhesives such as HMA are manufactured by superimposing the side portions of the pair of side sheet members on the long axis C side on the applied adhesive and joining them. In addition, the absorbent article of the present invention can be manufactured by any manufacturing process conventionally known in addition to the manufacturing process of the aforementioned surface member. Therefore, it does not require special manufacturing equipment and complicated manufacturing processes, and can be easily performed manufacture.
又,在本實施形態,如圖2及圖4所示,中
央薄片構件21係為了在前述第1重複部A1,於長度方向L的兩側部之各端緣側形成第2自由緣部21a、21b,而在
與前述兩側部的端緣分離之部位,與前述側部薄片構件22、23相互地接合。圖5係顯示中央薄片構件的第2自由緣部的作用之示意圖。如圖5所示,當在中央薄片構件21的長度方向L兩側部之端緣側形成第2自由緣部21a、21b時,已被排出的尿液等的體液U透過表面構件2而被吸收體3吸收後,即使因壓力的負荷、超過吸收體3的吸收容量等,造成已被前述吸收體3所吸收的體液U'朝表面構件2側滲出,也可藉由前述中央薄片構件21的長度方向L的兩側部之第2自由緣部21a、21b,抑制前述體液U'朝表面構件2的肌膚面側流出(所謂的逆流),因此,能夠防止前述體液U'附著於穿用者的肌膚面,其結果,能夠保持穿用者的肌膚清潔。
In addition, in this embodiment, as shown in FIGS. 2 and 4, the
前述第2自由緣部21a、21b的寬度方向W之
長度WF'係前述第2自由緣部21a、21b可發揮前述作用則未特別限定,可作成任意的長度。例如,本發明的第2自由緣部之寬度方向W的長度WF'係與前述第1自由緣部的寬度方向W之長度WF相同程度的1mm~20mm的範圍內,理想為3mm~15mm的範圍內,更理想為4mm~10mm的範圍內。又,從已被吸收體所吸收的體液之逆流抑制效果、接合強度等的點來看,前述第2自由緣部的寬度方向W之長度WF'與前述第1接合部的寬度方向W之長度WB的比(WF'/WB)為5/3以上為佳。
The length W F′ of the second
又,在本實施形態,表面構件2是由一片的
中央薄片構件21與2片的側部薄片構件22、23之總計3
片的薄片構件所構成,但,本發明不限於這樣的結構,亦可藉由4片以上的薄片構件構成表面構件。
Furthermore, in this embodiment, the
圖6係各側部薄片構件22、23分別藉由2片
的薄片材221、222、231、232所構成之本發明的其他實施形態之吸收性物品的斷面圖。亦可如圖6所示,前述各側部薄片構件22、23藉由將朝吸收性物品1的長度方向L延伸之4片的薄片材221、222、231、232併設於寬度方向W上來構成。在這樣的實施形態,前述4片的薄片材221、222、231、232中,位於吸收性物品1的長軸線C側之2片的薄片材221、231係在與前述長軸線C側相反側之各側部,讓與前述長軸線C側相反側之相鄰接的其他2片的薄片材222、232之位於前述長軸線C側的各側部從肌膚面側重疊。又,位於前述長軸線C側之2片的薄片材221、231與鄰接於前述長軸線C側的相反側之其他2片的薄片材222、232重疊之各自的第2重複部A2係為了在鄰接於前述長軸線C側之相反側的2片的薄片材222、232之各側部的端緣側形成第3自由緣部222a、232a,在與前述各側部的端緣分離的部位相互地接合。
FIG. 6 is a cross-sectional view of an absorbent article according to another embodiment of the present invention composed of two
又,從所排出之體液的阻擋效果或接合強 度、前述體液的吸入容易度等的觀點來看,在前述第2重複部A2,前述第3自由緣部的寬度方向W之長度對第2接合部的寬度方向W之長度的比係5/3以上為佳。 In addition, from the viewpoint of the blocking effect or bonding strength of the discharged body fluid, the ease of inhalation of the body fluid, etc., in the second repeating portion A 2 , the length of the third free edge in the width direction W is equal to the second The ratio of the length of the joining portion in the width direction W is preferably 5/3 or more.
當分別藉由複數片的薄片材構成表面構件的 各側部薄片構件時,由於在前述表面構件的肌膚面側之面 上,將沿著吸收性物品的長度方向L延伸之自由緣部以複數段的方式形成在寬度方向W上,故,能夠更確實地遮斷停止已被排出的體液朝寬度方向W之流動,能更有效果地防止前述體液橫向洩漏。 When the surface member is composed of a plurality of sheets When each side sheet member is on the surface of the surface member on the skin side Since the free edge portion extending along the longitudinal direction L of the absorbent article is formed in a plurality of steps in the width direction W, the flow of the discharged body fluid in the width direction W can be more reliably blocked, It can effectively prevent the aforementioned lateral leakage of body fluid.
又,亦可如圖6所示,4片的薄片材221、
222、231、232中,位於前述長軸線C側之2片的薄片材221、231係在與鄰接於前述長軸線C側的相反側之其他2片的薄片材222、232之前述第2重複部A2,為了在與前述長軸線C側之相反側的各側部的端緣側形成第4自由緣部221b、231b,在與前述各側部的端緣分離的部位相互地接合。
In addition, as shown in FIG. 6, of the four
又,從已被吸收體吸收的體液之逆流抑制效 果、接合強度等的觀點來看,在第2重複部A2,前述第4自由緣部的寬度方向W之長度對第2接合部的寬度方向W之長度的比係5/3以上為佳。 In addition, from the viewpoint of the backflow suppression effect of the body fluid that has been absorbed by the absorbent body, the bonding strength, and the like, in the second repeating portion A 2 , the length in the width direction W of the fourth free edge portion is the width of the second bonding portion The ratio of the length of the direction W is preferably 5/3 or more.
當在位於前述長軸線C側的2片的薄片材之 與前述長軸線C側相反側的各端緣側亦形成自由緣部時,藉由該自由緣部,能夠更有效地抑制前述這樣已被吸收體吸收的體液逆流,能夠更確實地防止前述體液附著於穿用者的肌膚。 When two of the thin sheets on the long axis C side When each end edge side opposite to the long axis C side also forms a free edge portion, the free edge portion can more effectively suppress the backflow of the body fluid that has been absorbed by the absorbent body, and can more reliably prevent the body fluid Attaches to the wearer's skin.
