Description
本發明係關於生理用護墊、生理褲(經期用衛生棉片)、失禁護墊等吸收性物品。The present invention relates to an absorbent article such as a physiological pad, a physiological pants (a sanitary napkin for menstruation), an incontinence pad, and the like.
近年來之吸收性物品呈現薄型傾向，例如，本申請人曾在日本特開平9－156014號公報中申請過利用薄型之吸收性薄片，比以往之吸收性物品薄而吸收性能優異之吸收性物品。In recent years, the absorbent article has a tendency to be thinner. For example, Japanese Patent Application Laid-Open No. Hei 9-156014 has applied an absorbent article which is thinner than the conventional absorbent article and has excellent absorption performance. .
而，該薄型之吸收性物品由於薄型，故在穿用在身體時因身體之扭動而發生歪扭時，吸收性物品與身體之間容易產生間隙。因此要求提高穿用在身體時之形狀之穩定性。另一方面，對於吸收性物品之貼身性，本申請人曾提出日本特開平10－99372號公報所載之技術之專利申請案。又，為維持穿用中之平坦度，使其難以發生歪扭及褶皺，曾提出在中央區域強化剛軟度之專利申請案(參照日本特開2000－225138號公報)。但，即使將此等技術原原本本地適用於使用如上所述之薄型之吸收性薄片之吸收性物品，也不能充分獲得所希望之形狀穩定性。On the other hand, since the thin absorbent article is thin, when it is worn by the body and twisted by the body, a gap is easily generated between the absorbent article and the body. Therefore, it is required to improve the stability of the shape when worn in the body. On the other hand, the applicant has filed a patent application for the technique disclosed in Japanese Laid-Open Patent Publication No. Hei 10-99372. In addition, in order to maintain the flatness during wearing, it is difficult to cause twisting and wrinkles, and a patent application for strengthening the softness in the central region has been proposed (refer to Japanese Laid-Open Patent Publication No. 2000-225138). However, even if these techniques are originally applied locally to an absorbent article using the thin absorbent sheet as described above, the desired shape stability cannot be sufficiently obtained.
本發明係鑑於上述問題而設計者，係關於一種難以歪扭、穿用時之形狀穩定性優異、對身體之貼身性良好之吸收性物品。The present invention has been made in view of the above problems, and relates to an absorbent article which is difficult to twist, has excellent shape stability when worn, and has good fit to the body.
為達成前述目的，本發明所提供之吸收性物品係包含構成肌膚接觸面之正面薄片、構成非肌膚接觸面之背面薄片、及介在兩薄片間之吸收性層，實質上形成縱長形者，前述吸收性層在寬度方向中央區域具有層數較多之部分，在該層數較多之部分具有使穿用形狀穩定化之裝置。In order to achieve the above object, the absorbent article provided by the present invention comprises a front sheet constituting a skin contact surface, a back sheet constituting a non-skin contact surface, and an absorbent layer interposed between the two sheets, and substantially forming a longitudinal shape. The absorbent layer has a portion having a large number of layers in the central portion in the width direction, and has a device for stabilizing the wearing shape in a portion having a large number of layers.
以下，一面參照圖式，一面依據合適之實施型態說明本發明。Hereinafter, the present invention will be described with reference to the drawings in accordance with an appropriate embodiment.
圖1~圖3係模式地表示本發明之吸收性物品適用於生理用護墊之第1實施型態。在此等圖中，符號1表示生理用護墊(以下僅稱護墊)。Fig. 1 to Fig. 3 schematically show a first embodiment in which the absorbent article of the present invention is applied to a physiological pad. In these figures, reference numeral 1 denotes a physiological pad (hereinafter simply referred to as a pad).
如圖1、圖2(a)及(b)所示，本實施型態之護墊1係包含肌膚接觸面2、非肌膚接觸面3、及介在肌膚接觸面2與非肌膚接觸面3間之吸收性層4，實質上形成縱長形。肌膚接觸面2構成正面薄片、非肌膚接觸面3構成背面薄片，吸收性層4配置於兩薄片之間。在護墊1之肌膚接觸面2，為提高由正面薄片之吸收性，並防止吸收性層4之歪扭，利用由肌膚接觸面2側之壓花加工而形成凹部20(但在圖2(b)中，為方便起見，省略凹部20之圖示)。凹部20係形成於後述之中央吸收部40之外側。凹部20最好達到吸收性層4之下部附近。As shown in Fig. 1, Fig. 2(a) and (b), the pad 1 of the present embodiment includes a skin contact surface 2, a non-skin contact surface 3, and a skin contact surface 2 and a non-skin contact surface 3. The absorbent layer 4 is substantially elongated. The skin contact surface 2 constitutes a front sheet, and the non-skin contact surface 3 constitutes a back sheet, and the absorbent layer 4 is disposed between the sheets. In the skin contact surface 2 of the pad 1, in order to improve the absorbability of the front sheet and prevent the twist of the absorbent layer 4, the concave portion 20 is formed by embossing by the skin contact surface 2 side (but in Fig. 2 ( In b), the illustration of the recess 20 is omitted for convenience. The concave portion 20 is formed on the outer side of the central absorption portion 40 to be described later. The recess 20 preferably reaches the vicinity of the lower portion of the absorbent layer 4.
構成肌膚接觸面2之正面薄片係由透液性薄片所構成。在該透液性薄片可無特別限定地使用以往在此種吸收性物品所使用之透液性薄片。作為該透液性薄片，只要可使液體穿透至上述吸收性層4，並無限制，但以具有接近於貼身內衣之觸感者特別理想。作為此種透液性薄片，例如，可列舉熱可塑性樹脂之織布、不織布及多孔性薄片等。尤其，作為可提供接近於貼身內衣之觸感之透液性薄片，最好使用將芯層成分使用聚丙烯或聚酯，外層成分使用聚乙烯之夾心構造型(含並列型)複合纖維利用梳理纖維形成網化後，利用透氣法形成不織布(也可在其後於特定處施行開孔處理)之透液性薄片，從透液性較高之點(乾爽感)言之，最好使用由低密度聚乙烯等之聚烯烴構成之開孔薄片。The front sheet constituting the skin contact surface 2 is composed of a liquid permeable sheet. The liquid permeable sheet used in such an absorbent article can be used without any particular limitation. The liquid permeable sheet is not limited as long as it can penetrate the absorbent layer 4, but it is particularly preferable to have a touch close to the underwear. Examples of such a liquid permeable sheet include a woven fabric of a thermoplastic resin, a nonwoven fabric, and a porous sheet. In particular, as a liquid permeable sheet which can provide a touch close to the underwear, it is preferable to use a sandwich type (including side-by-side type) composite fiber in which the core layer component is made of polypropylene or polyester, and the outer layer component is made of polyethylene. After the fiber is formed into a network, a liquid-permeable sheet which is formed into a non-woven fabric by a gas-permeable method (which may be subjected to a perforation treatment at a specific point thereafter) is preferably used from a point of high liquid permeability (dry feeling). An apertured sheet of polyolefin such as low density polyethylene.
構成非肌膚接觸面3之背面薄片係最好由不透液性薄片所構成。在該不透液性薄片可無特別限定地使用以往在此種吸收性物品所使用之不透液性薄片。作為此不透液性薄片，例如，可使用由T型機頭或圓形口模熔融擠出熱可塑性樹脂中添加有無機化合物或有機化合物之填充料之混合物而形成薄膜，接著，將此薄膜單軸或雙軸拉伸而獲得透濕性之薄片。又，使用將紡絲黏合型不織布與熔融流不織布複合化之薄片(例如SM、SMS、SMMS等)，從透氣性與柔軟性之點言之，亦相當理想。又，在吸收性層之非肌膚接觸面隔著設置防漏性薄片之情形，背面薄片不具有不透液性也無妨。The back sheet constituting the non-skin contact surface 3 is preferably composed of a liquid-impermeable sheet. The liquid-impermeable sheet can be used without any particular limitation, and the liquid-impermeable sheet conventionally used in such an absorbent article can be used. As the liquid-impermeable sheet, for example, a mixture of a filler in which an inorganic compound or an organic compound is added by melt-extruding a thermoplastic resin from a T-type head or a circular die can be used to form a film, and then, the film is formed. Uniform or biaxial stretching to obtain a moisture permeable sheet. Further, it is also preferable to use a sheet (for example, SM, SMS, SMMS, etc.) which combines a spunbonded nonwoven fabric and a melt flow non-woven fabric, in terms of gas permeability and flexibility. Further, in the case where the non-skin contact sheet is provided on the non-skin contact surface of the absorbent layer, the back sheet may not have liquid impermeability.
吸收性層4具有疊層薄型之吸收性薄片之構成。作為使用於吸收性層4之前述吸收性薄片，例如，可列舉日本特開平9－156014號公報之[發明之實施型態]之欄所載之吸收性薄片。又，利用黏著劑或濕潤時之黏著性將聚合物固定於薄的紙與紙之間之薄片、在熔融流不織布製造時散播聚合物而在不織布化之同時將聚合物固定化之薄片、及直接將聚合物聚合．固定於纖維集合體之薄片等使用作為薄型之吸收性薄片也相當理想。The absorbent layer 4 has a structure in which a thin absorbent sheet is laminated. The absorbent sheet to be used in the absorbent layer 4 is, for example, an absorbent sheet contained in the column of the "invention of the invention" of JP-A-9-156014. Further, a sheet in which a polymer is fixed between a thin paper and paper by an adhesive or a wet adhesive property, a sheet which is dispersed at the time of production of the melt flow non-woven fabric, and which is immobilized while being non-woven, and Polymerize the polymer directly. It is also preferable to use a sheet or the like fixed to a fiber assembly as a thin absorbent sheet.
吸收性層4在寬度方向之中央區域具有層數較多之處。在此，所謂寬度方向之中央區域，係指由護墊1之寬度方向中心分別至兩側15~25 mm之範圍之區域，在本實施型態之護墊1中，與後述之吸收性薄片41之寬度相同。在護墊1中，吸收性層4係在對應於排泄部位之位置之中央吸收部40，疊層較多層之吸收性薄片，使其吸收性能高於其他部份。The absorptive layer 4 has a large number of layers in the central portion in the width direction. Here, the central region in the width direction refers to a region ranging from the center in the width direction of the pad 1 to a range of 15 to 25 mm on both sides. In the pad 1 of the present embodiment, an absorbent sheet to be described later is used. 41 has the same width. In the pad 1, the absorbent layer 4 is attached to the central absorbent portion 40 at a position corresponding to the excretion portion, and a plurality of layers of the absorbent sheet are laminated to have higher absorption performance than the other portions.
如圖2(a)所示，中央吸收部40係重疊2片吸收性薄片41，再於此等吸收性薄片41之外側上下配設另外之吸收性薄片42。中央吸收部40係具有吸收性薄片之數相異之部份，即僅有吸收性薄片42之2層部分402、與此等之間之4層之部分404。又，在圖2(a)中，為便於瞭解起見，將各薄片劃成具有間隙，但實際上，各薄片係密接著。護墊1係在中央吸收部40，吸收性層4係在其寬度方向具有層數相異之部份。As shown in Fig. 2(a), the central absorbent portion 40 is formed by laminating two sheets of the absorbent sheet 41, and another absorbent sheet 42 is disposed above and below the outer side of the absorbent sheet 41. The central absorbent portion 40 has a portion that differs in the number of absorbent sheets, i.e., only the two layer portions 402 of the absorbent sheet 42 and the four portions 404 between the layers. Further, in Fig. 2(a), for the sake of easy understanding, each of the sheets is formed to have a gap, but actually, the sheets are closely attached. The pad 1 is attached to the central absorbing portion 40, and the absorptive layer 4 has a portion having a different number of layers in the width direction.
圖2(a)及(b)所示之吸收性層4之厚度T4、長度L4及寬度W4係依照穿用者之使用情景而適宜地加以設定。考慮到盡量不造成護墊穿用時之阻力感或不舒服感時，理想之吸收性層4之厚度T4較好為1~5 mm，更好為1.5~3 mm。長度L4為250~450 mm，寬度W4為60~85 mm。The thickness T4, the length L4, and the width W4 of the absorbent layer 4 shown in Figs. 2(a) and 2(b) are appropriately set in accordance with the use situation of the wearer. The thickness T4 of the desired absorbent layer 4 is preferably from 1 to 5 mm, more preferably from 1.5 to 3 mm, in view of the fact that the resistance or uncomfortable feeling when the pad is worn is not caused as much as possible. The length L4 is 250~450 mm and the width W4 is 60~85 mm.
考慮到不對製品長度方向之彎曲造成阻力時，最好中央吸收部40之前端部位於距離吸收性層4之最前端部40~100 mm(在圖2中以S40表示)，長度L40為80~140 mm。最好中央吸收部40之長度L40為吸收性層4之長度L4之25~60%。In view of not causing resistance to bending in the longitudinal direction of the product, it is preferable that the front end portion of the central absorbent portion 40 is located 40 to 100 mm from the foremost end portion of the absorbent layer 4 (indicated by S40 in Fig. 2), and the length L40 is 80~. 140 mm. Preferably, the length L40 of the central absorbent portion 40 is 25 to 60% of the length L4 of the absorbent layer 4.
本實施型態之護墊1在中央吸收部40之層數較多之部分，即前述吸收性薄片之4層之部分404之兩側緣部及中央部具有使穿用形狀穩定化之裝置(以下又僅稱穩定化裝置)5。The pad 1 of the present embodiment has a device having a large number of layers in the central absorbent portion 40, that is, a portion of the four layers 404 of the absorbent sheet, and a central portion having a device for stabilizing the wearing shape ( Hereinafter, it is only referred to as a stabilizing device).
穩定化裝置5係由非連續地設於中央吸收部40之4層之部分404之兩側緣部及中央部之壓縮部54所構成。壓縮部54係在中央吸收部40之寬度方向以3行於長度方向隔著特定間隔非連續地設置。如此，非連續地設置壓縮部54時，不會損及護墊1之長度方向(前後方向)之彎曲情形，且可使在薄片(層)較多之部分與較少之部分之交界容易曲折，且在層較多之部分剛性容易過高之中央吸收部40之剛性在其中央部分至兩側緣部變得均勻，且在將護墊1穿用於身體時，如圖3所示，可使中央吸收部40不會局部地，特別是不會在層數較多之部分404與層數較少之部分402之交界集中地彎曲，可在寬度方向整體地穩定地維持凸形狀。藉此，可抑制護墊1之肌膚接觸面2與身體B之間產生間隙。吸收體之寬度方向之剛性可藉施行穩定化處理而與穩定化處理前相比，呈現50~80%之剛性，但長度方向之剛性則幾乎無變化，與穩定化處理前相比，呈現90~110%之剛性。理想之施行穩定化處理後之剛性值為0.5~2.5 cN/cm。The stabilizing device 5 is composed of a compression portion 54 which is provided discontinuously on both side edges and a central portion of the four portions 404 of the central absorption portion 40. The compression portion 54 is provided discontinuously at a predetermined interval in three directions in the longitudinal direction of the central absorption portion 40 with a predetermined interval therebetween. When the compression portion 54 is provided discontinuously, the bending of the pad 1 in the longitudinal direction (front-rear direction) is not impaired, and the boundary between the portion of the sheet (layer) and the smaller portion can be easily bent. And the rigidity of the central absorbent portion 40 in which the rigidity of the layer is excessively high is uniform in the central portion to the both side edges, and when the pad 1 is worn for the body, as shown in FIG. The central absorbing portion 40 can be bent locally without being partially localized, in particular, at a boundary between the portion 404 having a large number of layers and the portion 402 having a small number of layers, and the convex shape can be stably maintained as a whole in the width direction. Thereby, a gap can be suppressed between the skin contact surface 2 of the pad 1 and the body B. The rigidity of the absorbent body in the width direction can be stabilized by a stabilization process of 50 to 80% compared with that before the stabilization treatment, but the rigidity in the longitudinal direction is almost unchanged, and is 90 as compared with that before the stabilization treatment. ~110% rigidity. The ideal stiffness after stabilization is 0.5~2.5 cN/cm.
又，壓縮部54從提高吸收性層4與正面薄片之接觸性而使液體之移動性良好之觀點，最好由吸收性層4之非肌膚接觸面3側被推壓設置。壓縮部54例如可藉使其通過具有對應於此等配設位置之凸部之熱壓花輥之方式加以設置。壓縮部54最好其吸收性薄片彼此被壓縮，再被熱接合而設置熱接合部。Further, the compression portion 54 is preferably provided by the non-skin contact surface 3 side of the absorbent layer 4 from the viewpoint of improving the contact between the absorbent layer 4 and the front sheet and improving the fluid mobility. The compressing portion 54 can be provided, for example, by passing it through a hot embossing roll having a convex portion corresponding to the arrangement position. Preferably, the compressing portion 54 is such that the absorbent sheets are compressed with each other and then thermally joined to provide a thermal joint.
如圖2(a)及(b)所示，層數較多之部分與較少之部分之交界(在本實施型態中，2層部分402與4層部分404之交界)與壓縮部54之間隔d若考慮到可藉交界部份之層數之差異緩和受到可撓性之影響之側部之歪扭時，以3~10 mm較為理想。又，壓縮部54寬度方向之間隔dw54若考慮到對製品寬度方向之彎曲，不提高剛度時，以5~15 mm較為理想。另外，若考慮到對製品長度方向之彎曲，不提高剛度時，壓縮部54長度方向之間隔dl54以5~15 mm較為理想。As shown in FIGS. 2(a) and (b), the boundary between the portion having a larger number of layers and the smaller portion (in the present embodiment, the boundary between the two-layer portion 402 and the four-layer portion 404) and the compression portion 54 are shown. The interval d is preferably 3 to 10 mm in consideration of the difference in the number of layers that can be borrowed from the boundary portion to alleviate the twist of the side affected by the flexibility. Further, the interval dw54 in the width direction of the compression portion 54 is preferably 5 to 15 mm in consideration of bending in the width direction of the product and not increasing the rigidity. Further, in consideration of the bending in the longitudinal direction of the product, when the rigidity is not increased, the interval dl54 in the longitudinal direction of the compressed portion 54 is preferably 5 to 15 mm.
壓縮部54之深度、壓縮部54之面積、壓縮部54之合計面積係依照中央吸收部40之層數加以設定。又，若考慮到對製品長度方向及寬度方向之彎曲，不造成阻力時，壓縮部54之深度最好為2~5 mm、壓縮部54之各個面積最好為0.7~4 mm2 、壓縮部54之合計面積最好為10~75 mm2 。The depth of the compression portion 54, the area of the compression portion 54, and the total area of the compression portion 54 are set in accordance with the number of layers of the central absorption portion 40. Further, in consideration of bending in the longitudinal direction and the width direction of the product, the depth of the compressed portion 54 is preferably 2 to 5 mm, and the area of the compressed portion 54 is preferably 0.7 to 4 mm 2 , and the compression portion is not caused. The total area of 54 is preferably 10 to 75 mm 2 .
如以上所說明，本實施型態之護墊1由於作為穩定化裝置5，在吸收性層4之中央吸收部40之層數較多之部分404之中央部及兩側部具有壓縮部54，故除了可防止在中央吸收部40之層數較多之部分與較少之部分之交界之曲折外，並在中央吸收部40整體上，可謀求可撓性之均勻化。因此，難以發生歪扭，可使護墊1穿用於身體上時之形狀保持穩定，使對身體之貼身性保持良好。As described above, the pad 1 of the present embodiment has the compressing portion 54 at the central portion and both side portions of the portion 404 having a large number of layers of the central absorbent portion 40 of the absorbent layer 4 as the stabilizing device 5. Therefore, in addition to the meandering of the boundary between the portion having a large number of layers of the central absorbing portion 40 and the smaller portion, the flexibility of the entire central absorbing portion 40 can be made uniform. Therefore, it is difficult to cause the twisting, and the shape of the pad 1 can be kept stable when it is worn on the body, so that the fit to the body is kept good.
圖4(a)及(b)係模式地表示本發明之吸收性物品適用於護墊之另一實施型態之圖，且相當於圖2(a)及(b)之圖。在此等圖中，對於與前述第1實施型態之吸收性層4之中央吸收部40相同之部分附以同一符號，省略其說明。因此，對於無特別說明之部分，適宜地適用前述第1實施型態之說明。4(a) and 4(b) are views schematically showing another embodiment of the absorbent article of the present invention applied to the pad, and correspond to the drawings of Figs. 2(a) and 2(b). In the drawings, the same portions as those of the central absorbent portion 40 of the absorbent layer 4 of the first embodiment are denoted by the same reference numerals and will not be described. Therefore, the description of the first embodiment will be suitably applied to the portion which is not particularly described.
圖4(a)及(b)所示之第2實施型態之護墊1'具有肌膚接觸面2之兩側部被蝶翼部之表面層之側部薄片6所包覆，並接合於側部薄片6之型態。在側部薄片6，可以使用以往此種護墊所使用之習知之側部薄片，例如將與前述透液性之正面薄片同樣之纖維表面施行撥水油劑處理而不織布化之側部薄片、或紡絲黏合型不織布、或將紡絲黏合型不織布(S)與熔融流不織布(M)複合化之薄片(例如SM、SMS、SMMS等)。側部薄片使用疏水性或撥水性之薄片時，可獲得降低側漏之效果。The pad 1' of the second embodiment shown in Figs. 4(a) and 4(b) has both sides of the skin contact surface 2 covered by the side sheet 6 of the surface layer of the butterfly wing portion, and joined to The shape of the side sheets 6 . In the side sheet 6, a conventional side sheet which is conventionally used for such a mat, for example, a side sheet which is treated with a water-repellent agent and is not woven by the surface of the liquid-permeable front sheet, may be used. Or a spunbonded nonwoven fabric or a sheet (for example, SM, SMS, SMMS, etc.) in which a spunbonded nonwoven fabric (S) and a melt flow non-woven fabric (M) are combined. When a hydrophobic or water-repellent sheet is used for the side sheet, the effect of reducing side leakage can be obtained.
護墊1'之中央吸收部40係以一張吸收性薄片41之兩端部與上方(正面薄片側)之略中央部之間無重疊寬或有若干間隙G41之方式相向地曲折，並以吸收性薄片42包入吸收性薄片41之方式被設置。吸收性薄片42之端部係在吸收性薄片41之下方(背面薄片側)之略中央部以有重疊寬W42之方式被重疊。又，在圖4(a)中，為便於瞭解起見，將各薄片劃成在上下具有間隙，但實際上，各薄片係密接著，吸收性薄片42之兩側部也被曲折成無間隙狀態。考慮到不對製品寬度方向之彎曲造成阻力時，間隙G41最好為0~3 mm。基於同樣之理由，重疊寬W42最好為2~15 mm。The central absorbing portion 40 of the pad 1 ′ is bent in such a manner that the end portions of the one absorbent sheet 41 and the slightly central portion of the upper side (front sheet side) are not overlapped or have a plurality of gaps G41 therebetween, and The absorbent sheet 42 is provided in such a manner as to be wrapped in the absorbent sheet 41. The end portion of the absorbent sheet 42 is overlapped at a slight central portion of the lower side (back sheet side) of the absorbent sheet 41 so as to have an overlapping width W42. Further, in Fig. 4(a), for the sake of easy understanding, each of the sheets is formed to have a gap on the upper and lower sides, but actually, the sheets are closely attached, and both side portions of the absorbent sheet 42 are also zigzag to have no gap. status. The gap G41 is preferably 0 to 3 mm in consideration of resistance to bending of the width direction of the product. For the same reason, the overlap width W42 is preferably 2 to 15 mm.
在上述層構成中，中央吸收部40具有僅有吸收性薄片42之2層之部分402、此等之間之4層之部分404及5層之部分(間隙G41之部分除外)405，中央吸收部40之吸收性薄片係在4層之部分404具有穩定化裝置5。In the above layer configuration, the central absorbent portion 40 has only a portion 402 of two layers of the absorbent sheet 42, a portion 404 between the four layers and a portion of the fifth layer (except for the portion of the gap G41) 405, central absorption The absorbent sheet of the portion 40 has a stabilizing device 5 in a portion 404 of the four layers.
穩定化裝置5係由非連續地設於中央吸收部40之4層之部分404之橢圓形狀之多數壓縮部54所構成。壓縮部54係以間隔dw54在中央吸收部40之寬度方向非連續地設成2行，以具有間隔dl54在長度方向非連續地設置。The stabilizing device 5 is composed of a plurality of embossed portions 54 that are discontinuously provided in a portion 404 of four layers of the central absorbing portion 40. The compression portion 54 is discontinuously arranged in two rows at the interval dw54 in the width direction of the central absorption portion 40, and is provided discontinuously in the longitudinal direction with the interval d1.
本實施型態之護墊1'另外作為穩定化裝置5，在中央吸收部40之層數較多之4層之部分404具有壓縮部54、與中央吸收部40之吸收性薄片41、42之端部局部地不重疊之疊層構造之組合，與前述第1實施型態之護墊同樣地，除了可防止在中央吸收部40之層數較多之部分與較少之部分之交界之曲折外，並在中央吸收部40整體上，可謀求可撓性之均勻化。因此，難以發生歪扭，可使護墊穿用於身體上時之形狀保持穩定，使對身體之貼身性保持良好。The pad 1' of the present embodiment is additionally used as the stabilizing device 5, and the portion 404 of the four layers having a large number of layers in the central absorbing portion 40 has a compressing portion 54 and an absorbent sheet 41, 42 of the central absorbing portion 40. The combination of the laminated structures in which the end portions are not partially overlapped is similar to the protective pad of the first embodiment, except that the boundary between the portion having a large number of layers of the central absorbent portion 40 and a small portion can be prevented. Further, in the entire central absorbing portion 40, the flexibility can be made uniform.

The absorbent-only layer containing no liquid permeable sheet (front sheet) and liquid-impermeable sheet (back sheet) was used as a sample. The sample was adjusted to a size of 30 mm × 30 mm centering on the measurement site (specifically, each stabilization device). The bending gap of the bending tester was 10 mm, so when measuring the width direction, it was adjusted so that the stabilization device was the center, and N=3 was measured at each part. In the measurement of the width direction, the sample was attached to the bending tester in such a manner that the bending test of the back sheet was performed first, and in the measurement of the longitudinal direction, the sample was attached to the bending test of the front sheet first. Bending test machine. The measurement results were made using a special software (KES-FB SYSTEM data measurement program Ver.7.07WJ), and the measured value of the back side sheet side with a bending curvature of 2.0 (1.98 to 2.02) in the width direction was used as " In the longitudinal direction, the measured value of the front side of the sheet having a bending curvature of 2.0 (1.98 to 2.02) is referred to as a "rigidity value in the longitudinal direction".
利用上述評估方法評估之結果，實施例1及實施例2之任何護墊皆呈現平穩地順著透明模特兒之胯間部之形狀，難以發生歪扭，穿用於身體上時之形狀穩定性優異，中央．側部雙方對身體之貼身性相當良好。實施例3之護墊在中央部發生若干凹陷，中央之貼身性雖比實施例1、2略差，但兩側部之貼身性相當良好。對此，比較例1之護墊則發生大的中央凹陷，在側部也發生大的歪扭。因此，對透明模特兒之胯間部之貼身性較差，穿用型態不良。Using the results of the evaluation methods described above, any of the pads of Examples 1 and 2 exhibited a smooth shape along the crotch portion of the transparent model, which was difficult to be twisted and the shape stability when worn on the body. Excellent, central. Both sides of the side are quite good for the body. The pad of Example 3 had a few depressions in the center portion, and the center fit was slightly inferior to those of Examples 1 and 2, but the fit between the both sides was quite good. On the other hand, in the pad of Comparative Example 1, a large central depression occurred, and a large twist occurred in the side portion. Therefore, the fit of the transparent model is poor, and the wearing pattern is poor.
依據本發明，可提供難以歪扭、穿用時之形狀穩定性優異、對身體之貼身性良好之吸收性物品。According to the present invention, it is possible to provide an absorbent article which is difficult to twist, has excellent shape stability when worn, and has good fit to the body.
