Description

本考案は、下半身体液吸収用芯体に関し、特に、下半身体液吸収用双芯体高吸収芯体に関する。 The present invention relates to a lower half body fluid absorbing core, and more particularly to a lower half body fluid absorbing twin core high absorption core.

紙おむつや生理用ショーツ等の下半身体液吸収用製品の重要な構造の一つが芯体であり、体液を吸収し、一時的に保存するための芯体は、その性能の良し悪しが紙おむつや生理用ショーツ全体の製品品質を決定する。 One of the important structures of lower body fluid absorption products such as disposable diapers and sanitary shorts is the core, and the core for absorbing and temporarily storing body fluids has good or bad performance. Determine the overall product quality of the shorts.

使い捨て紙おむつのような、現在、市場で販売されている下半身体液吸収用製品の芯体は、一般に、以下の２つに分類される。１つ目は、包覆型または未包覆のフラッフパルプに高分子吸収顆粒を混合した構造であり、このタイプの構造は、薄くて快適な製品を作ることが要求されれば、必然的に、吸収芯体が液体を吸収した後、凝集または断裂の状況が生じる。 The cores of products for absorbing lower body fluids currently sold in the market, such as disposable paper diapers, are generally classified into the following two types. The first is a structure in which polymer-absorbing granules are mixed with enveloped or unencapsulated fluff pulp, and this type of structure is inevitably required if a thin and comfortable product is required. After the absorbent core absorbs the liquid, an agglomeration or tearing situation occurs.

２つ目は、複合芯体または双芯体であり、二層または多層の、無塵紙、不織布等の吸水性の高強度材料に高分子吸収顆粒を組み合わせてなり、このタイプの芯体は製品全体の薄さと快適性を良好に保持し、吸収芯体の液体吸収後の凝集または断裂状況を解決するが、このタイプの芯体の幅は固定され、製品化後の股部の幅は比較的広く、液体吸収後、一部の吸収膨張が過大となり、着用後、ユーザに大きな不快感をもたらし、特に嬰児はＯ脚が形成されやすくなる。 The second type is a composite core or twin core, which consists of a double-layer or multi-layer, water-absorbing high-strength material such as dust-free paper or non-woven fabric combined with polymer absorbent granules. Maintains good overall thinness and comfort and solves the agglomeration or tearing situation after absorption of liquid in the absorbent core, but the width of this type of core is fixed and the width of the crotch after commercialization is compared In general, after absorption of liquid, a part of the absorption expansion becomes excessive, causing a great discomfort to the user after wearing, and particularly an infant tends to form an O-leg.

本実用新案は、上述の課題を解決するため、液体吸収後、その幅がユーザの使用状況に応じて適応変化する、下半身体液吸収用双芯体高吸収芯体を提供することを目的とする。 In order to solve the above-described problems, the present utility model aims to provide a bi-core body high-absorption core body for absorbing lower body fluid, whose width is adaptively changed according to the use state of the user after liquid absorption.

本考案は、下半身体液吸収用双芯体高吸収芯体であって、上層の吸収層と下層の貯液層を含み、前記双芯体高吸収芯体の使用時の前後方向を前後方向とし、前記吸収層の左右幅は前記貯液層の左右幅より大きく、前記吸収層はその前後軸線の左右両側の位置にそれぞれ、前後方向の線状通孔または凹部を備え、前記線状通孔または凹部の前後端は、前記吸収層の前後辺縁の内側にある。 The present invention is a biaxial body high absorption core body for lower body fluid absorption, comprising an upper absorption layer and a lower liquid storage layer, the front-rear direction when the bicore body high absorption core is in use as the front-rear direction, The left-right width of the absorbent layer is larger than the left-right width of the liquid storage layer, and the absorbent layer has linear through-holes or recesses in the front-rear direction at positions on the left and right sides of the front-rear axis, respectively. The front and rear ends of are inside the front and rear edges of the absorbent layer.

線状通孔または線状凹部を備えることにより、ユーザの活動時には吸収層の両側は適応可能なように上向きまたは下折れになり、これにより、芯体全体の左右幅が縮小して、体へのフィット感がさらに高まる。同時に、線状通孔または線状凹部はさらに排水機能を備え、いっそうスムーズに液体を貯液層に引き込み、液体が漏れるのを防ぐことができる。 By providing a linear through hole or a linear recess, both sides of the absorbent layer can be upwardly or downwardly folded so that it can be adapted during user activity, thereby reducing the lateral width of the entire core body, A feeling of fitting increases further. At the same time, the linear through holes or the linear recesses are further provided with a drainage function, so that the liquid can be drawn more smoothly into the liquid storage layer and the liquid can be prevented from leaking.

好ましくは、前記線状通孔または凹部の中間部は直線であって前記吸収層の前後軸線に接近し、前記線状通孔または凹部の前後両端は直線またはカーブ曲線であって前記吸収層の前後軸線から遠ざかり、あるいは、前記線状通孔または凹部の中間部は前記吸収層の前後軸線に接近し、かつ、前後両端は前記吸収層の前後軸線から遠ざかって、円弧を形成する。 Preferably, an intermediate portion of the linear through hole or recess is a straight line and approaches the longitudinal axis of the absorption layer, and both front and rear ends of the linear through hole or recess are a straight line or a curved curve, and A distance from the front-rear axis, or an intermediate portion of the linear through hole or recess approaches the front-rear axis of the absorbent layer, and front and rear ends move away from the front-rear axis of the absorbent layer to form an arc.

かかる形状の吸収層は、その両側が上向きまたは下折れになる過程において、人体の太腿の形状といっそう一致し、着用の快適性をさらに向上させる。 The absorbent layer having such a shape further matches the shape of the human thigh in the process in which both sides of the absorbent layer are upwardly or downwardly folded, thereby further improving the comfort of wearing.

好ましくは、前記吸収層は高分子吸収顆粒層を混合したフラッフパルプであり、前記貯液層は親水性材料と高分子吸収顆粒層を組み合わせてなる直線状の層である。 Preferably, the absorbent layer is a fluff pulp mixed with a polymer-absorbing granule layer, and the liquid storage layer is a linear layer formed by combining a hydrophilic material and a polymer-absorbing granule layer.

貯液層は、無塵紙のような目の詰んだ薄片材料で高分子吸収顆粒を包んで作られる。吸収層は拡散と浸透作用を果たす。貯液層はむらのない吸収と保液作用を果たし、芯体表層をさらさらにして、着用をいっそう快適にし、おむつかぶれを防止する。貯液層の高い強度により、凝集または断裂状況を防止することができる。吸収層と貯液層の材料はいずれも既存技術の通常の材料であるが、かかる選択により、芯体全体は比較的薄く、吸収層は柔らかくて吸収に都合がよく、また、十分な支持強度を有するという目的を達成できる。 The liquid reservoir is made by wrapping polymer absorbent granules with a clogged flake material such as dust-free paper. The absorbent layer performs diffusion and osmosis. The liquid storage layer performs non-uniform absorption and liquid retention, further improves the core surface layer, makes wearing more comfortable, and prevents diaper rash. Aggregation or tearing can be prevented by the high strength of the reservoir. The material of the absorption layer and the liquid storage layer are both ordinary materials of the existing technology. However, with this selection, the entire core is relatively thin, the absorption layer is soft and convenient for absorption, and sufficient support strength is provided. The purpose of having

実用上の需要に基づき、前記吸収層と貯液層の外側は不織布で覆われる。 Based on practical demand, the outer sides of the absorbent layer and the liquid storage layer are covered with a nonwoven fabric.

本実用新案の有益な効果は、以下のとおりである。
本考案は吸収層に２つの線状通孔または線状凹部を設け、貯液層の左右幅を吸収層の左右幅より小さく設計することにより、吸収層の左右両側に「浮遊」効果を形成させ、液体吸収面積を増加させるとともに、吸収層の左右幅をユーザの使用状況に応じて上向きまたは下折れに適応変化させることができ、芯体の上表面と左右辺縁をさらに体にフィットさせて装着快適性を著しく向上させ、幅が変化しない芯体が嬰児のO脚を形成させやすくするという問題を防止するとともに、液体がさらにスムーズに貯液層に引き込まれ、液体の漏れを防止する。 The beneficial effects of this utility model are as follows.
In the present invention, two linear through holes or linear recesses are provided in the absorption layer, and the “horizontal” width of the liquid storage layer is designed to be smaller than the horizontal width of the absorption layer, thereby creating a “floating” effect on both the left and right sides of the absorption layer. In addition to increasing the liquid absorption area, the left and right width of the absorbent layer can be adaptively changed upward or downward depending on the usage situation of the user, and the upper surface and left and right edges of the core body are further fitted to the body This significantly improves wearing comfort and prevents the core that does not change its width from easily forming the O-leg of the infant, and also allows liquid to be drawn more smoothly into the reservoir and prevents liquid leakage. .

以下では、図面とあわせて本実用新案について、さらに説明する。図１および図２に示すように、本実用新案の下半身体液吸収用双芯体高吸収芯体は、上層の吸収層３および下層の貯液層４、吸収層３と貯液層４の外側を覆う不織布１を含む。前記双芯体高吸収芯体の使用時の前後方向が前後方向（すなわち、図１における上下方向）であり、吸収層３の左右幅は貯液層４の左右幅より大きく、具体的な大きさはニーズに基づき定まるが、本実施例においては、貯液層４の左右幅は、吸収層３の２つの線状通孔２の間の左右幅よりも若干大きい。 Below, this utility model is further demonstrated with drawing. As shown in FIG. 1 and FIG. 2, the lower half body fluid absorption double-core body high-absorption core of the utility model has an upper absorption layer 3, a lower liquid storage layer 4, an outer side of the absorption layer 3 and the liquid storage layer 4. The covering nonwoven fabric 1 is included. The front-rear direction when using the double-core high-absorption core is the front-rear direction (that is, the vertical direction in FIG. 1), and the left-right width of the absorbent layer 3 is larger than the left-right width of the liquid storage layer 4, and has a specific size. However, in this embodiment, the lateral width of the liquid storage layer 4 is slightly larger than the lateral width between the two linear through holes 2 of the absorbent layer 3.

吸収層３は、その前後軸線の左右両側の位置にそれぞれ前後方向の線状通孔２を備え、線状通孔２の前後端と吸収層３の前後の辺縁の間の距離はニーズに基づき定まるが、本実施例においては、線状通孔２の前後端と吸収層３の前後の辺縁の間の距離は線状通孔２の前後長の約３分の２である。線状通孔２の中間部は直線で吸収層３の前後軸線に接近し、線状通穴２の前後両端はカーブ（直線でもよい）であって、かつ吸収層３の前後軸線から遠ざかる。あるいは、線状通孔２の形状は、線状通孔２の中間部は吸収層３の前後軸線に接近し、かつ前後両端は吸収層３の前後軸線から遠ざかって円弧を形成するものでもよい。吸収層３は高分子吸収顆粒層を混合したフラッフパルプであり、貯液層４は低比重高強度の親水性材料と高分子吸収顆粒層を組み合わせてなる直線状の層である。 The absorption layer 3 has linear through holes 2 in the front and rear direction at positions on the left and right sides of the front and rear axis, respectively, and the distance between the front and rear ends of the linear through holes 2 and the front and rear edges of the absorption layer 3 is a need In this embodiment, the distance between the front and rear ends of the linear through hole 2 and the front and rear edges of the absorbent layer 3 is about two thirds of the front and rear length of the linear through hole 2. The middle part of the linear through hole 2 is a straight line and approaches the front and rear axis of the absorption layer 3, and both front and rear ends of the linear through hole 2 are curved (may be a straight line) and away from the front and rear axis of the absorption layer 3. Alternatively, the shape of the linear through-hole 2 may be such that an intermediate portion of the linear through-hole 2 approaches the front-rear axis of the absorption layer 3 and both front and rear ends are away from the front-rear axis of the absorption layer 3 to form an arc. . The absorbent layer 3 is a fluff pulp mixed with a polymer absorbent granule layer, and the liquid storage layer 4 is a linear layer formed by combining a hydrophilic material having a low specific gravity and a high strength and a polymer absorbent granule layer.

図１と図２をあわせると、使用時、一般に本実用新案にかかる双芯体高吸収芯体は熱融着により、パンツ体に張り合わせられ（張り合わせ幅は線状通孔２の左右幅よりもやや大きいか、等しい。）、紙おむつまたは生理用ショーツを形成する；両面テープによって、本双芯体高吸収芯体は一時的に女性用下着に貼り付ける生理用ナプキン用にもなる。この種の状況においては、実際の利用の便利のために、一般に、本双芯体高吸収芯体に羽を追加し、既存の生理用ナプキンの形状を形成することが必要である。 1 and 2, when used, the biaxial high-absorption core body according to the utility model is generally bonded to the pants body by heat fusion (the width of the bonding is slightly larger than the width of the linear through hole 2). Large or equal)), forming a paper diaper or sanitary shorts; by means of double-sided tape, the double-core superabsorbent core also becomes a sanitary napkin that is temporarily affixed to women's underwear. In this kind of situation, it is generally necessary to add wings to the present bi-core superabsorbent core to form the shape of an existing sanitary napkin for the convenience of practical use.

使用過程において、ユーザがしゃがむ、または、座る姿勢をとるときには、吸収層３は自然に伸展し、その左右幅が最大の状態となり、ユーザは快適性を感じる。ユーザが、両太腿が接近した起立状態または歩行状態のときには、線状通孔２により、吸収層３の両側はおのずと上向きまたは下折れになり、一方で芯体全体の左右幅を減少させ、他方で芯体の左右辺縁がさらに太腿にフィットして、快適性が向上する。ユーザが起立または歩行状態からしゃがむ、または座る姿勢となった場合には、吸収層３は、所定の弾性により平らな状態に回復し、同様に、ユーザの快適性を保証する。 In the course of use, when the user squats down or sits down, the absorbent layer 3 naturally extends and its left-right width is maximized, and the user feels comfortable. When the user is standing or walking with both thighs approaching, the linear through hole 2 naturally causes both sides of the absorbent layer 3 to be folded upward or downward, while reducing the lateral width of the entire core, On the other hand, the left and right edges of the core are further fitted to the thighs, improving comfort. When the user is in a posture of squatting or sitting from a standing or walking state, the absorbent layer 3 recovers to a flat state by a predetermined elasticity, and similarly guarantees the user's comfort.

上記実施例は、本実用新案の好ましい実施例にすぎず、本考案に対してなんらの制限にもならず、創造的労働を経ずに上述の実施例に基づき実現されるものでありさえすれば、すべて本実用新案の権利範囲に属するものとみなされるべきである。 The above embodiment is only a preferred embodiment of the utility model, does not limit the present invention, and can only be realized based on the above embodiment without creative labor. All should be regarded as belonging to the scope of rights of this utility model.
