本考案は、吸収体厚肉部（立体部）を有する生理用ナプキンに係り、特に着用 者へのフィット性を良好とする生理用ナプキンに関する。 The present invention relates to a sanitary napkin having a thick-walled portion (three-dimensional portion) of an absorbent body, and more particularly to a sanitary napkin having a good fit to a wearer.
【０００２】[0002]
生理用ナプキンに要求される品質としては、装着時に股間によくフィットする ことが重要である。従来より供されている生理用ナプキンにおける排液の吸収・ 保持のための吸収体は、使用面の前面に均一に入っているか、もしくは長手方向 の両端まで入っていた。 しかし、前記吸収体は、半剛性体である綿状パルプを使用しており、装着時に 長手方向前後部が十分に湾曲せず、フィット感の悪いものであった。フィット性 が悪いと、使用時に経血が吸収体によって十分吸収保持されず、特に横漏れの原 因となることが多かった。 A good quality of a sanitary napkin is that it fits well between the groins when worn. The absorbent body for absorbing and retaining the drainage in the sanitary napkins that has been conventionally provided has been evenly placed on the front surface of the use surface, or has been extended to both ends in the longitudinal direction. However, the absorbent body uses cotton-like pulp, which is a semi-rigid body, and the front and rear portions in the longitudinal direction are not sufficiently curved at the time of mounting, resulting in poor fit. If the fitting property is poor, menstrual blood is not sufficiently absorbed and held by the absorber during use, which often causes lateral leakage.
【０００３】 近年、身体へのフィット性および経血吸収性を高めるために、吸収体の両側縁 から外方に延在するフラップ部に吸収体長手方向に収縮力を作用させるための弾 性伸縮部材を設け、その収縮力により吸収体を舟形に湾曲させるとともに、スポ ット吸収性を高めるために吸収体の排液部に相当する部分を二層構造とした生理 用ナプキンが提案されている。In recent years, in order to enhance the fit to the body and the absorbability of menstrual blood, elastic expansion and contraction for applying a contracting force in the longitudinal direction of the absorbent body to the flap portion extending outward from both side edges of the absorbent body. A sanitary napkin has been proposed in which a member is provided, the absorbent body is curved in a boat shape by its contracting force, and the portion corresponding to the drainage part of the absorbent body has a two-layer structure in order to improve the absorbency of the spot. .
【０００４】[0004]
しかしながら、従来より提案されている生理用ナプキンは、図５に示されるよ うに、生理用ナプキンの側部フラップ部に弾性伸縮部材１０を設けても、吸収体 の排液部を二層構造の厚肉としているため、該厚肉部での吸収体剛度が上がるた め、吸収体の前後端の持ち上げ力が不十分となり、フィット性が劣るものとなっ ている。また、排液部を厚肉とすることで吸収体の総量の増加によりスポット吸 収性を向上させることができるとしても、吸収体排液部の剛性も上がりゴワツキ 感がでて、装着感の悪いものとなる場合が多かった。さらに、吸収体の厚肉部以 外の前後端のみが上下に持ち上げられると、排液部に積層された下部吸収体の前 後縁が段部Ａを形成し、これが装着時に違和感となって残る場合がある。 However, the conventionally proposed sanitary napkin, as shown in FIG. 5, has a two-layer structure for the drainage part of the absorbent body even if the elastic stretchable members 10 are provided on the side flap parts of the sanitary napkin. Since the absorbent body is thick, the rigidity of the absorbent body in the thickened area is increased, and the lifting force at the front and rear ends of the absorbent body becomes insufficient, resulting in poor fit. Although the drainage section can be made thicker to improve the spot absorbency due to an increase in the total amount of the absorber, the rigidity of the absorber drainage section is also increased and the feel of stiffness is increased and the wearing feeling is improved. It was often bad. Further, when only the front and rear ends other than the thick part of the absorbent body are lifted up and down, the front and rear edges of the lower absorbent body laminated in the drainage part form a stepped portion A, which makes the user feel uncomfortable at the time of mounting. It may remain.
【０００５】 そこで、本考案の主たる課題は、吸収体排液部を厚肉とする生理用ナプキンに 係り、厚肉部によるゴワツキ感を無くすとともに、吸収体全体を舟形に成形しフ ィット感を向上させた生理用ナプキンを提供するものである。Therefore, the main problem of the present invention relates to a sanitary napkin having a thickened drainage portion of the absorbent body, which eliminates a feeling of stiffness due to the thickened portion, and at the same time, the entire absorbent body is molded into a boat shape to provide a fit feeling. It is intended to provide an improved sanitary napkin.
【０００６】[0006]
前記課題は、透液性シートと、不透液性シートと、両シート間に介装される排 液を吸収する吸収体とを備えた実質的に細長形状の生理用ナプキンにおいて、 前記吸収体中間の排液部を厚肉とするとともに、少なくとも長手方向中間にお いて上記吸収体の両側縁から外方に延在する透液性シートおよび不透液性シート の少なくとも一方によりフラップ部を形成し、この各フラップ部に長手方向の収 縮力を作用させる弾性伸縮部材を設け、かつ弾性伸縮部材の長さを前記吸収体厚 肉部の長手方向長さ以上とするとともに、前記厚肉部の長手方向形成範囲を前記 弾性伸縮部材の配設範囲内としたことで解決できる。 The problem is a substantially elongated sanitary napkin including a liquid-permeable sheet, a liquid-impermeable sheet, and an absorbent body that is interposed between the sheets and that absorbs drainage. The middle drainage part is thick, and the flap part is formed by at least one of the liquid-permeable sheet and the liquid-impermeable sheet extending outward from both side edges of the absorber at least in the middle in the longitudinal direction. Then, each flap portion is provided with an elastic expansion / contraction member for exerting a compressive force in the longitudinal direction, and the length of the elastic expansion / contraction member is made equal to or more than the longitudinal direction length of the absorbent body thick portion, and the thick portion It is possible to solve the problem by setting the forming range in the longitudinal direction within the range in which the elastic expansion / contraction member is arranged.
【０００７】[0007]
本考案では、たとえば、吸収体中間の排液部に吸収体を重ねるなどの方法によ り厚肉とするとともに、サイドフラップ部に弾性伸縮部材を設ける際に、特に弾 性伸縮部材の長さを前記吸収体厚肉部の長手方向長さ以上とするとともに、前記 厚肉部の長手方向形成範囲を前記弾性伸縮部材の配設範囲内とする。したがって 、弾性伸縮部材の収縮力が、吸収体の厚肉部全体に渡って効果的に作用し、吸収 体の厚肉部を含めて舟形に湾曲させるため、全体のフィット感が向上するととも に、厚肉部の前後端が角部を形成しなくなる。さらに、弾性伸縮部材の収縮力が 、吸収体の厚肉部を長手方向に圧縮する結果、図２に示されるように、厚肉部を 使用面側に円弧状に膨出させた中高形状（立体部）とするため、股間形状にフィ ットするようになり、経血の漏れを無くすことができる。 In the present invention, for example, when the absorbent body is thickened by a method such as stacking the absorbent body on the drainage section in the middle of the absorbent body, and when the elastic elastic members are provided on the side flaps, the length of the elastic elastic member is particularly important. Is greater than or equal to the length in the longitudinal direction of the thick part of the absorbent body, and the range in which the thick part is formed in the longitudinal direction is within the disposition range of the elastic stretchable member. Therefore, the contracting force of the elastic expansion / contraction member acts effectively over the entire thick portion of the absorber, and the thick portion of the absorber is curved into a boat shape, which improves the overall fit. The front and rear ends of the thick wall portion do not form a corner. Further, as a result of the contracting force of the elastic expansion / contraction member compressing the thick wall portion of the absorber in the longitudinal direction, as shown in FIG. 2, the thick wall portion is bulged in an arc shape on the side of the use surface ( Since it is a three-dimensional part, it fits in the shape of the crotch, and the leakage of menstrual blood can be eliminated.
【０００８】[0008]
次に、実施例に基づいて本考案を詳細に説明する。 図１は、本考案に係る生理用ナプキンを使用面側から見た平面図であり、装着 時には図１の上方が腹側で、下方側が背側となる。同図において、１は不織布ま たは孔開きプラスチックシートなどからなる透液性シートであり、２はポリエチ レンシートなどからなる不透液性シートであり、その間に吸収体３が介装されて いる。このナプキンの平面形状は全体として細長く、吸収体３の長手方向中央部 分、すなわち股間相当部分が若干括れている。 Next, the present invention will be described in detail based on embodiments. FIG. 1 is a plan view of the sanitary napkin according to the present invention viewed from the side of the use surface, and the upper side of FIG. 1 is the abdominal side and the lower side is the dorsal side when worn. In the figure, 1 is a liquid-permeable sheet made of non-woven fabric or perforated plastic sheet, etc., 2 is a liquid-impermeable sheet made of polyethylene sheet, etc., and an absorber 3 is interposed between them. . The planar shape of this napkin is elongated as a whole, and the central portion in the longitudinal direction of the absorbent body 3, that is, the crotch-corresponding portion is slightly constricted.
【０００９】 また、透液性シート１と不透液性シート２は、吸収体３の周縁から外方に延在 して、両シート１、２がホットメルトなどの接着剤またはヒートシールなどによ り重ね合わされ、フラップ部Ｆが形成されている。不透液性シート２の下面には 、ズレ止めホットメルト接着剤７が適宜のパターンで塗布されており、これは剥 離紙８により被服されている。装着時には、この剥離紙８を剥離し、ホットメル ト接着剤７部分をショーツに圧着させて、ナプキンのズレ止めを図っている。Further, the liquid-permeable sheet 1 and the liquid-impermeable sheet 2 extend outward from the peripheral edge of the absorbent body 3 so that both sheets 1 and 2 can be used as an adhesive such as hot melt or heat seal. And the flap portion F is formed. On the lower surface of the liquid-impervious sheet 2, a slip-preventing hot melt adhesive 7 is applied in an appropriate pattern, which is covered with a release paper 8. At the time of mounting, the release paper 8 is peeled off, and the hot melt adhesive 7 portion is pressed against the shorts to prevent the napkin from being displaced.
【００１０】 前記吸収体３は、図２の横断面図に示されるように、上部吸収体３１と下部吸 収体３２との二重構造となっている。下部吸収体３２は、ナプキン長手方向中間 部であって幅方向中間部分に設けられ、吸収体３の排液部のみを厚肉部Ｄとして いる。この二重構造によれば、経血が排出される部分の吸収体の総量が多いので 吸収性能が高まる。また、上部吸収体３１と下部吸収体３２は、その形態保持力 の補強のために、テッシュなどからなる紙綿台紙９等によって被包することがで きる。前記厚肉部Ｄの総厚Ｔ0 は１０〜２５mm、好ましくは１２〜１８mmの範囲 とするのが望ましく、またそれ以外の一般部分の厚みＴ1 は２〜１０mm、好まし くは２〜６mmの範囲とするのがよい。吸収体の前記厚さＴ0 、Ｔ1 の決定に当た っては昼用と夜用とを考慮し、昼用は装着感に重きを置き、夜用については前後 漏れに重きをおいて、前記範囲内で適宜決定するのが望ましい。ただし、一般部 分の厚みＴ1 を薄くする場合には、違和感および携帯性の点からは好ましいので あるが、吸収体自体にコシがなくなるため、弾性伸縮部材４による収縮を受けて 横ジワが入り易くなるとともに、手触りでの厚感がなくなるため、紙綿にパルプ 不織布を混入したものを使用すると薄い場合であっても程よい剛性を付与するこ とができる。また、水溶性高分子樹脂バインダーやホットメルト接着剤を散布す るなどにより剛性を付与することもできる。The absorbent body 3 has a double structure of an upper absorbent body 31 and a lower absorbent body 32, as shown in the cross-sectional view of FIG. The lower absorbent body 32 is provided in the widthwise intermediate portion of the napkin in the longitudinal direction, and only the drainage portion of the absorbent body 3 is the thick portion D. According to this double structure, since the total amount of the absorber in the portion where menstrual blood is discharged is large, the absorption performance is improved. Further, the upper absorbent body 31 and the lower absorbent body 32 can be wrapped with a paper cotton backing paper 9 made of tissue or the like in order to reinforce the shape retaining force. It is desirable that the total thickness T 0 of the thick portion D is in the range of 10 to 25 mm, preferably 12 to 18 mm, and the thickness T 1 of other general portions is 2 to 10 mm, preferably 2 to 6 mm. It is better to set the range. In determining the thicknesses T 0 and T 1 of the absorber, considering the daytime and nighttime use, the daytime wear should be given a high feeling of wearing comfort, and the nighttime use should be focused on front and rear leakage. It is desirable to appropriately determine within the above range. However, it is preferable to reduce the thickness T 1 of the general portion from the viewpoint of discomfort and portability, but since the absorbent body itself has no elasticity, the elastic stretchable member 4 contracts to cause lateral wrinkles. Since it becomes easy to enter and the thick feeling on touch is lost, the use of a paper cotton mixed with a pulp nonwoven fabric can impart a moderate rigidity even when it is thin. Further, rigidity can be imparted by spraying a water-soluble polymer resin binder or a hot melt adhesive.
【００１１】 さらに、前記厚肉部の両側部分であって、やや腹側寄りのサイドフラップ部Ｆ において、透液性シート１と不透液性シート２との間に弾性伸縮部材４が介装さ れ、その伸長状態においてホット接着剤により固着一体化されている。弾性伸縮 部材４としては、１本または平行の複数本の糸ゴム、または帯状のゴム、あるい はウレタンなどの弾性発泡帯などを用いることができる。Further, at the side flap portions F 1 on both sides of the thick portion and slightly on the ventral side, the elastic stretchable member 4 is interposed between the liquid permeable sheet 1 and the liquid impermeable sheet 2. In the stretched state, they are fixed and integrated with a hot adhesive. As the elastic expansion / contraction member 4, it is possible to use one or a plurality of parallel rubber threads, a band-shaped rubber, or an elastic foam band such as urethane.
【００１２】 前記弾性伸縮部材４は、その収縮力により、半剛性体たる二重構造の吸収体３ を舟形に湾曲させ、フィット感を向上させるとともに、横漏れおよび前後漏れを 防止するものであるが、仮に従来例に従って弾性伸縮部材の長さＸを前記厚肉部 長Ｓより短くすると、図５に示されるように、下部吸収体体１１が配設された厚 肉部Ｄは、他の部分より剛性が高いため、これを湾曲させることができず、結果 的に吸収体の前後端の持ち上げが不十分になるとともに、下部吸収体１１の前後 端の稜部Ａが突出し、違和感を伴うこととなる。そこで本考案においては、特に 弾性伸縮部材長Ｘと吸収体３の厚肉部長さＳとの相対的関係を図示されるように 、弾性伸縮部材長さＸを厚肉部長さＳよりも長くするとともに、厚肉部Ｄの長手 方向形成範囲を前記弾性伸縮部材４の配設範囲内としている。これにより、厚肉 部分Ｄをも含めて強制的に屈曲させるため全体のフィット感が向上させるととも に、下部吸収体３２の前後端が角張ることがなくなる。The elastic expansion / contraction member 4 bends the absorber 3 having a double structure, which is a semi-rigid body, into a boat shape by its contracting force to improve the fit and to prevent side leakage and front / rear leakage. However, if the length X of the elastic elastic member is made shorter than the thick portion length S according to the conventional example, as shown in FIG. 5, the thick portion D in which the lower absorbent body 11 is arranged is Since the rigidity is higher than that of the part, it cannot be bent, and as a result, the front and rear ends of the absorbent body are not lifted up sufficiently, and the ridges A at the front and rear ends of the lower absorbent body 11 project, which causes a feeling of strangeness. It will be. Therefore, in the present invention, in particular, the elastic stretchable member length X is made longer than the thick portion length S, as shown in the relative relationship between the elastic stretch member length X and the thick portion length S of the absorber 3. At the same time, the range in which the thick portion D is formed in the longitudinal direction is set within the range in which the elastic expansion / contraction member 4 is arranged. Accordingly, the thick portion D is forcibly bent, so that the overall fit is improved and the front and rear ends of the lower absorbent body 32 are prevented from being angular.
【００１３】 また、弾性伸縮部材４の収縮力が吸収体厚肉部Ｄの全体に作用し、吸収体３を 長手方向に圧縮し、図３に示されるように、フリーな状態で厚肉部を使用面側に 円弧状に膨出させた中高部Ｎを形成し、股間形状に沿った形状とするため、該厚 肉部Ｄの装着感を良好とし、ゴワツキ感をなくすことができる。前記弾性伸縮部 材長さＸと厚肉部長さＳとの相対差は、大きすぎると非中高部分にシワを作って しまい、逆に隙間の原因ともなるため、厚肉部Ｄの前後側のそれぞれに０〜２０ mm、好ましくは６〜１２mm程度の余裕を持たせるようにして弾性伸縮部材長さＸ を決定するのが望ましい。Further, the contracting force of the elastic expansion / contraction member 4 acts on the entire thick body portion D of the absorbent body, compressing the absorbent body 3 in the longitudinal direction, and as shown in FIG. Since the middle height portion N that bulges in an arc shape is formed on the side of the use surface and has a shape that follows the crotch shape, the thick portion D can be worn comfortably and the stiff feeling can be eliminated. If the relative difference between the elastic portion length X and the thick portion length S is too large, wrinkles will be created in the non-middle and high portions, which in turn causes a gap. It is desirable to determine the elastic stretchable member length X 1 so that each has a margin of about 0 to 20 mm, preferably about 6 to 12 mm.
【００１４】 一方、吸収体３の排液部からの漏れを効果的に防ぐためには、吸収体３を長手 方向に舟形に成形するとともに、図３に示されるように、吸収体３の両側部のサ イドフラップ部Ｆを立ち上げて、横断面形状をも舟形に成形し、排液部分の全体 をコップ状に成形するのが望ましい。ここで、生理用ナプキン長手方向の舟底部 分を着用者にフィットさせるためには、その長さＬを５０〜７０mm以上とする必 要がある。したがって、弾性伸縮部材４の長さＸとしては、製品長Ｍの１／３以 上の長さを確保するとともに、少なくとも１００mm以上（フリー状態時）とする のがよい。On the other hand, in order to effectively prevent leakage from the drainage part of the absorbent body 3, the absorbent body 3 is formed in a boat shape in the longitudinal direction, and as shown in FIG. It is desirable that the side flap F of the above is raised and the cross-sectional shape is also formed into a boat shape, and the entire drainage portion is formed into a cup shape. Here, in order to fit the wearer to the boat bottom portion in the longitudinal direction of the sanitary napkin, the length L thereof needs to be 50 to 70 mm or more. Therefore, as the length X of the elastic expansion / contraction member 4, it is preferable to secure a length not less than 1/3 of the product length M and at least 100 mm or more (in the free state).
【００１５】 また、弾性伸縮部材４の収縮力は、下部吸収体３２を屈曲させるとともに、立 体的に持ち上げて中高部Ｎを形成し、さらに前後端側を舟形に成形するために、 弾性伸縮部材配設長Ｘに製品状態で１０〜３０％の収縮率を与えるように弾性伸 縮部材４を配設する。収縮率が１０％未満であると、前記した本考案生理用ナプ キンが望む形状に成形することができず、また収縮率が３０％を超えると、逆に 横方向にシワを作ってしまいその隙間から横漏れを起こす原因となる。使用する 弾性伸縮部材としては、前述のように、種々のものを使用することができるが、 本実施例においては、着用者への当りの柔らかさ、密着性等を考慮して１４０％ 伸長時パワーが１００〜２００gf/20mm の発泡ウレタン素材を用いている。In addition, the contraction force of the elastic expansion / contraction member 4 causes the lower absorbent body 32 to bend and rise vertically to form the middle-high part N, and further to form the front and rear end sides into a boat shape. The elastic expansion / contraction member 4 is arranged so as to give a contraction rate of 10 to 30% to the member arrangement length X in a product state. If the shrinkage ratio is less than 10%, the sanitary napkin of the present invention cannot be molded into the desired shape, and if the shrinkage ratio exceeds 30%, wrinkles are formed in the lateral direction. It may cause side leakage from the gap. As the elastic expansion / contraction member to be used, various kinds can be used as described above, but in the present embodiment, in consideration of the softness to the wearer, the adhesion, etc. Uses urethane foam material with power of 100-200gf / 20mm.
【００１６】 なお、透液性シート１と吸収体３または紙綿台紙９とは平面的にスパイラル状 態に塗布したホットメルト接着剤により接合することができる。また、上記例で は透液性シート１と不透液性シート２との両者でフラップ部Ｆを全周に形成して あるが、一方のシートを延在させて二重重ねしてフラップ部Ｆを形成することも できる。The liquid-permeable sheet 1 and the absorbent body 3 or the paper backing paper 9 can be joined by a hot-melt adhesive applied in a planar spiral state. Further, in the above example, the flap portion F is formed on the entire circumference of both the liquid-permeable sheet 1 and the liquid-impermeable sheet 2. However, one sheet is extended and double-lapped to form the flap portion. It is also possible to form F.

以上詳説のとおり、本考案によれば、吸収体排液部を厚肉とする生理用ナプキ ンであっても、厚肉部によるゴワツキ感を無くすことができるとともに、吸収体 全体を舟形に成形しフィット感を向上させることができる。 As described above in detail, according to the present invention, even with a sanitary napkin in which the drainage part of the absorbent body has a thick wall, it is possible to eliminate the feeling of stiffness due to the thick wall part and to form the entire absorbent body into a boat shape. The fit can be improved.
