Description

  The present invention relates to a wearing article that forms a waist opening and a pair of leg openings when worn, such as a deployable disposable diaper, a pants-type disposable diaper, and a diaper cover.

  In wearing articles such as unfolded disposable diapers, pants-type disposable diapers, and diaper covers, elastic members for three-dimensional gathers and elastic members for leg gathers are used to prevent misalignment and filth leakage during wearing, Some are arranged along the periphery of the left and right leg openings. Although it is a little special, especially as a diaper for a care recipient who wears for a long time, the absorbent polymer fixed inside the absorber gels and expands by liquid absorption to form a layer in which polymer beads are fixed Is disclosed (see Patent Document 1). This is because the body pressure between the human skin and the absorber is dispersed by the expansion of the beads and the shape of the sphere, especially when the absorbent body is worn for a long time with the body fluid absorbed. It has a preventive effect.

JP 2008-183159 A

  By the way, after wearing, various forces are applied to the diaper from the outside. In particular, when riding or holding an infant, the special piggyback strap is fixed along the crotch to the ventral and back sides, but in this case the infant's weight tends to concentrate on the crotch portion. , Diaper crotch will be pressed. Even when a baby is placed on a stroller or child seat, the belt is passed from the crotch to the abdomen and fixed, so the diaper is pressed by the belt. The inventors of the present invention focused on the fact that in such a scene, the portion from the infant's crotch to the abdomen or dorsal side is strongly pressed locally, and in particular, the fit around the thigh tends to be lost.

  In view of the above points, the present invention relieves the feeling of pressure from the skirt to the crotch even when a wearing article is worn, and particularly when using a fastener such as a piggyback strap, a hug belt, or a seat belt, It is an object of the present invention to provide a wearing article that exhibits high leakage resistance against excrement leakage from the skirt.

  The present invention is defined by a ventral portion, a dorsal portion, and a crotch portion between the two portions, and in a worn state, forms a waist opening and a pair of leg openings, and a liquid-impermeable sheet and the same A predetermined region in which a large number of particles that do not substantially absorb liquid are spread at least in the crotch region between the outer layer sheet and the liquid-impermeable sheet. It is intended to provide a wearing article arranged in the above.

  The wearing article of the present invention, when worn, especially when using a fastener such as a piggyback strap, a hug belt, or a seat belt, alleviates the feeling of pressure from the skirt to the crotch and leaks excrement from the crotch. High leakage resistance.

  FIG. 1 is a partially cut-away developed plan view showing an unfolded disposable diaper for infants as an embodiment of the wearing article of the present invention. In addition, although the diaper of this embodiment has a waist elastic member in the vicinity of a waist opening part, in FIG. 1, this waist elastic member is abbreviate | omitted. FIG. 2 is an enlarged cross-sectional view taken along the line II-II in FIG.

  As shown in FIG. 1, the deployable disposable diaper 10 of the present embodiment includes an abdominal side portion F, a back side portion R, and a crotch portion C positioned between the two portions, and is disposed on the skin contact surface side. A liquid-permeable surface sheet 1, a liquid-impermeable sheet 2, and an outer layer sheet 3, and an absorber 4 interposed between the surface sheet 1 and the liquid-impermeable sheet 2. On the left and right sides of the top sheet 1, a pair of side sheets 5, 5 that match the length in the longitudinal direction are joined together, leaving the part of the elastic member 8 that forms a three-dimensional gather unjoined. Yes. The overall developed shape of the diapers 10 laminated in this manner is a substantially vertically long hourglass shape as shown in FIG. 1, that is, both longitudinal ends (abdominal side portion F, back side portion R) thereof. It is made wide so that the crotch part C can be bundled.

  Between the liquid-impermeable sheet 2 and the outer layer sheet 3, there is a bag-like portion T in which a large number of particles 6 that do not substantially absorb liquid are filled in a predetermined area extending at least in the crotch C. Is formed. In the bag-like portion T, the particles 6 are not adhered, and the particles 6 inside the bag-like portion T have appropriate flexibility against pressure from the outside due to the mobility independent of the liquid-impermeable sheet 2 and the outer layer sheet 3. . Thereby, as will be described later, the local compressive force from the outside of the diaper exhibits a relaxing action and a preventive action against excrement leakage. The “substantially non-absorbing” in the particle 6 is not only a case where the liquid and moisture are not completely absorbed, but also a low absorptivity that does not hinder the mobility of the particle 6, particularly from the outside of the diaper. It means to include low absorbency that does not hinder mobility even by force.

  The disposable diaper 10 in this embodiment has a back side portion R arranged on the wearer's back side when worn, and the front side portion F is applied to the wearer's lower abdomen so that the crotch portion C is along the crotch. And the edge Wo which makes a waist opening part by the shape at the time of wear, and the edge Lo which makes a pair of leg opening part are comprised. In order to realize the fit and leakage prevention of the crotch part C of the diaper 10 which becomes three-dimensional when worn, the elasticity for forming a thread-like or thin string-like three-dimensional gather which forms a pair of standing leakage prevention cuffs on the side seat 5 A band 8 is provided. In addition, an elastic member 9 for forming leg gathers is provided between the side sheet 5 and the liquid-impermeable sheet 2 for the purpose of appropriately tightening the base of the foot and preventing leakage. The side seat 5 in FIG. 1 has a free edge position m of the leak-proof cuff and stands up so that this position protrudes toward the wearer's skin surface when worn. On the other hand, the side sheet 5 and the surface sheet 1 or the liquid-impermeable sheet 2 are joined from the base end position of the leak-proof cuff (not shown in the figure, generally the positions matching the left and right side edges of the surface sheet) to the side edges in the diaper width direction. The base end position is located between the left and right side edges of the absorbent body 4 and the elastic member 9 in the form of a string or string for forming leg gathers.

In the diaper 10 of the present embodiment, the bag portion T, as shown in FIG. 1, in plan view, a bag-shaped widthwise bag-shaped portion lateral edges k ₂ and longitudinal (X direction) (Y-direction) parts are upper and lower ends vertically long rectangular shape surrounded by the edge k _1. The bag-like portion T includes a portion corresponding to the crotch portion C of the absorbent body 4 in a plan view, and extends beyond the portion where the absorbent body 4 is disposed. The left and right edges k ₂ of the bag-like part forming the left and right ends of the bag-like part T are the edges of the joint part between the outer layer sheet 3 and the liquid-impermeable sheet 2, and from there to the outer sides of the right and left sides of the diaper. Both sheets are joined. Bag-like portion upper and lower edges k ₁ forming the upper and lower ends of the bag-like portion T is also similarly toward therefrom in the vertical direction outward of the diaper liquid impervious sheet 2 and the outer sheet 3 are bonded. Thus, the method of joining both sheets in a predetermined region is not particularly limited, and can be produced by a conventional method. In the present embodiment, the bag-like portion T includes: the bag portion upper and lower edges k ₁ and the other bag-like portion lateral edges k ₂ outer sheet 3 and a liquid-impermeable sheet 2 and is not bonded bag shape A large number of particles 6 are movably enclosed therein. Due to the mobility of the large number of particles 6, a flexible soft hitting bag portion T is formed.

FIG. 2 is an enlarged cross-sectional view taken along the line II-II in FIG. In the present embodiment, the bag-shaped portion T whose width direction is formed in a bag shape between the left and right edges k ₂ , k ₂ of the bag-shaped portion is disposed closer to the non-skin contact surface than the absorbent body 4 and is in a natural state. In the shape having a thickness t in the thickness direction at the central portion of the crotch C due to a large number of particles inside. The shape of the bag-like portion T can be deformed by pressure from the outside with an appropriate softness depending on the mobility of the particles 6. For example, when the compression of the arrow d ₁ is applied, a part of the particles 6 arranged there is pushed and moved to the periphery (arrow d ₅ ), and the thickness t changes in each part in the width direction while Move to position.

  The particles 6 arranged in this manner first act to absorb and disperse the force applied from the outside of the outer sheet, thereby reducing the intensive propagation of force to the absorber 4 and the body. Have. In the present embodiment, for example, if the hugging string 80 is put on the crotch of the infant 90 wearing the diaper 10 and lifted, the entire weight of the infant is applied to the crotch part C of the diaper 10. However, in the diaper 10 of this embodiment, since many particles 6 gather and have thickness, this absorbs the said compression force by a surface, Therefore The impact is relieved. As a result, the infant's crotch, buttocks, and lower abdomen are not over-pressed, and congestion and skin troubles at those portions can be reduced. In addition, even when an infant sits down on the floor from the bottom, the particle 6 can absorb and disperse the impact and relieve pain.

Further, in the present embodiment, the particles 6 absorb the compressive force from the outside and move so that the surface of the particles 6 follows and rises from the portion to the periphery as a whole. The movement of the particles 6 deforms the liquid-impermeable sheet 2 and the outer layer sheet 3, and an effect of fitting perfectly along the undulation of the body is obtained.
For example, as shown in FIG. 3, when an infant is held up and held, a force for pulling up the holding string 80 acts against the body weight. In particular, in the crotch part C, a force to pull up the cracked portion is applied in the dorsal direction, and in the ventral direction, a force to pull up the left and right inguinal ligaments and the left and right external oblique muscles around the crotch. For example, a baby about one year old has a weight of about 10 kg, and a strong force is concentrated on the soft part of the crotch C. Along with that, the elastic member 9 is also pulled and deformed so that a gap is greatly opened between the thigh and the sheet material of the diaper, and the fit at that portion is impaired. Further, at the crotch part C, the absorbent body 4 is also strongly pressed at the same time, and there is a possibility that excrement leaks from the aforementioned gap (arrow d ₄ ).
Even in such a case, in the diaper 10 of the present embodiment, the particles 6 arranged in a region where the compression force acts on the diaper (hereinafter referred to as a compression region p) are outward in the width direction (in FIG. 3). Escape to the arrow d ₅ ) and push the outer layer sheet 3 toward the skin surface. The extruded sheet material, together with the tightening of the leg gathers by the elastic member 9, fits around the soft rounded thigh of the infant. As a result, the contact surface spreads over a wide area from the root of the thigh of the wearer's inseam to the buttocks, and the perfect fit of the diaper is maintained, and a good wearing feeling and prevention of excrement from the inseam at this part are maintained. It is possible to achieve both leakage and compatibility. From this point of view, it is preferable that the bag-like portion T in which the particles 6 are present in the present embodiment is disposed at least at the center of the crotch portion.

FIG. 4 is a schematic explanation for explaining the state of the outer layer sheet 3 facing the abdominal side F and the back side R across the center point A of the crotch C when the diaper 10 of the present embodiment is mounted. FIG. Hereinafter, with reference to FIG. 4, the elastic part 9 and the urination point of the absorber 4 which cooperate with the influence which the compression force concerning a compression area has on the outer layer sheet 3 and the action which the movement of the particles 6 exerts on the outer layer sheet 41 and the defecation point 42 will be described together. In FIG. 4, the absorber 4 is omitted to schematically show the action of force, but the urination point 41 and the defecation point 42 are projected onto the outer layer sheet 3 and indicated by a one-dot chain line. The alternate long and short dash line around the leg opening edge Lo shows a part of the elastic member 9, but wrinkles due to contraction of the elastic member 9 are omitted.
In FIG. 4, an edge Lo (a skirt) that forms a leg opening for the right foot and the left foot is formed, and the surface on the near side becomes a surface toward the ventral side F. In the vicinity of the crotch center point A, which has been pressed by the hug string after wearing, is in a state of being bitten left and right. On the other hand, it will be in the state curved along the body also in the crotch direction applied from the abdominal side to the back side. The outer layer sheet 3 is shown as a saddle surface having a transverse main curvature surface 31 and a longitudinal main curvature surface 32. If the transverse main curvature surface 31 is a convex surface having a curvature in the negative (B) direction in the height direction (Z direction), the longitudinal main curvature surface 32 is a concave surface having a positive (U) curvature. Can be seen as That is, the saddle surface shape is a surface formed by intersecting two arcs having centers of curvature in opposite directions at arc vertices so as to be orthogonal to each other and extending both arcs consistently.

In FIG. 4, arrows d ₁ and d ₂ indicate a pressing force directly below the crotch C and a pressing force from the crotch C to the abdominal side F. In a normal wearing state, the sheet material around the leg opening edge Lo is fitted to both legs and thighs by the contraction force of the elastic member 9. However, if a strong compression force is applied in the directions of the arrows d ₁ and d ₂ after the mounting, the leg opening edge Lo (the left and right edge portions of the outer layer sheet 3) is moved together with the elastic member 9 in the direction of the arrow d ₃ due to the influence. Bending to create a gap between the thighs. In particular, as described above, because of the ridge surface shape whose curvature is reversed, when the transverse main curvature 31 in the width direction increases in this way, the other longitudinal main curvature 32 tends to decrease and moves away from the body undulation, synergistically. In addition, an extremely large gap is opened at the leg opening edge Lo. Further, in this case, since the urination point 41 of the absorber 4 is also pressed so as to be strongly squeezed, there is a possibility that excrement leaks to both ends in the width direction.
On the other hand, in the present embodiment, the particles 6 move toward the leg opening edge Lo (spinning) while absorbing and dispersing the compression force indicated by the arrows d ₁ and d ₂ . Since the moved particles 6 inflate the bag-like portion T near the leg opening edge Lo to fill the gap, the elastic member 9 returns to a predetermined position and fits tightly with the thigh. As a result, the leak-proof property of excrement from the skirt around the crotch is enhanced.
In FIG. 4, the action of the force is shown only on the front side facing the ventral side F, but the same applies to the side facing the back side R when the belt is disposed along the fissure. is there. Further, the description has been given centering on the crotch part C, but when the particles 6 are also arranged near the waist opening edge Wo of the diaper 10, similarly, the fit around the waist opening and the prevention of excrement therefrom. Leakage can be maintained. In addition, the outer layer sheet 3 is a soft material that is easier to deform than the non-stretchable liquid-impermeable sheet 2 and the absorbent body 4 from the viewpoint of appropriate surface deformability in the crotch-shaped crotch part C. preferable.

Since the particle 6 is used for a wearing article such as a diaper, it is preferable that the particle 6 is lightweight and has a strength that is not easily crushed by a pressing force from the outside. Moreover, it is preferable that the said particle | grain 6 is a shape which has curved surfaces, such as a spherical form and an ellipse, from a viewpoint of free movement. Such particles 6 are particles that do not substantially absorb liquid as described above, and there is little friction between the particles. Therefore, the particles 6 are easy to move in the bag-like portion T. For example, what is usually used for cushioning etc. with good impact absorption and touch, such as expanded polystyrene beads, can be used. Furthermore, the average particle diameter of the particles 6 is preferably 0.1 to 5 mm, and more preferably 0.5 to 2 mm so as not to impair the air permeability in the diaper. The density of the particles 6 in the bag-like portion T is the balance between shock absorption and ^mobility, preferably ^{0.001g / cm 3 ~0.5g / cm 3} , 0.01g / cm 3 ~0.1g / cm ³ is more preferred. Moreover, since the particle | grains 6 act as a buffer material, 3-30 mm is preferable and, as for the thickness t of the bag-shaped part T in the center part of the crotch part C, 5-15 mm is more preferable.

  In addition, the above-mentioned compression area | region p is an area | region which arises relatively by the relationship between the diaper and the compression force from the outer side, Comprising: It is not limited to the case of the strap shown in FIG. The compression region p has different spreads depending on various scenes, mainly around the central portion of the crotch part C in the width direction. For example, in the case of a stroller, the crotch three-dimensional crotch belt and the left and right waist belts are engaged on the abdomen side, so the crotch portion C to the abdominal side portion F of the diaper 10 is the compression region p. Further, in the case of a child seat, the inseam buckle and the left and right tongues on the abdomen are firmly pulled and engaged, so that not only the crotch C of the diaper 10 but also the abdomen F of the diaper 10 to the buttocks corresponding to the seat and Become.

The bag-like portion T is preferably located at a position corresponding to the compression region p from the viewpoint of preventing diaper kinking due to the compression force. This is because the compression region p is a portion that is easily subjected to a compression force, and is a portion that easily causes a loss of fit and leakage prevention. It is preferable that the bag-like portion T is defined so as to cover at least the urination point 41 and the defecation point 42 of the crotch portion C in the compression region p (see FIG. 1). It is not limited to the vertically long shape (see FIG. 1) shown in the diaper 10 of the present embodiment.
This point will be described in more detail with reference to FIG. The diaper 10 according to the present embodiment is divided into a left arched portion W ₁ , a central rectangular portion W ₂ , and a right arched portion W ₃ in the width direction, and a ventral side F, a crotch C, and a back side R in the longitudinal direction. This will be described in three parts. The left arcuate part W ₁ and the right arcuate part W ₃ are portions extending in an arcuate shape in the longitudinal direction outside the left and right end edges of the absorber 4. Central rectangular portion W ₂ is a rectangular portion of the vertically elongated to match the width of the right and left arcuate portions sandwiched by the absorbent body 4. The ventral part F, the crotch part C, and the dorsal part R are as described above. Crotch portion C corresponding to portions of the central rectangular section W ₂ is an excretion region 43 containing the urination point 41 and defecation point 42, a large portion of excretion. The urination point 41 is a part corresponding to the penis, and the defecation point is a part corresponding to the anus. Note that both points in the diaper 10 of the present embodiment indicate a case of a male infant, but in the case of a female, the position and the range are slightly different for an adult, and therefore can be appropriately determined according to it.

As described above, in the crotch portion C that is susceptible to the outermost pressing force, at least a portion corresponding to the excretion region 43 is preferably a bag-shaped portion T from the viewpoint of preventing excrement leakage. Further, in the width direction, the bag-shaped portion T may extend beyond the central rectangular portion W ₂ to the left and right arc-shaped portions W ₁ and W ₃ for the purpose of firmly fitting the sheet material around the thigh. In particular, it is particularly preferable that the elastic member 9 for forming leg gathers is located just before the elastic member 9 is disposed. In the longitudinal direction in addition, the bag-like portion T is according the waist opening W ₀ of the ventral and dorsal, and to prevent leakage therefrom, until the ventral F and the back side R It may extend.
Moreover, the said bag-shaped part T can be arbitrarily formed centering on the excretion area | region 43, and is not limited to the vertically long rectangular shape of this embodiment. For example, it may be an hourglass shape along the outer shape of the diaper 10. When the bag-shaped portion T has an hourglass shape, the particles 6 can be firmly arranged around the waist opening edge Wo so that the fit of this portion can be improved. The diapers of this embodiment and other embodiments described later can be manufactured by ordinary materials and processing methods applied to this type of product. Examples of the encapsulation of the particles 6 in the bag-shaped portion T include, for example, enclosing while sucking from the outer nonwoven fabric side, or using a static eliminator to prevent static electricity, for example, enclosing while performing corona discharge. .

  Moreover, the said absorber 4 is not restricted to the form of this embodiment, The thing divided | segmented into plurality in planar view may be sufficient. In this case, since the particles 6 can move rapidly along the dividing path of the absorbent body 4 even if the sheet material of the diaper is twisted, it is preferable in that the sheet material can be appropriately deformed. Examples of the divided shape of the absorber 4 include a shape divided into three in the width direction, and a shape divided into a plurality in the longitudinal direction. The effect of dividing into such a form is that the absorbent body is divided so that the absorbent body has a bending point, and it becomes easier to follow the body shape, and even when pressure is applied to the diaper from the outside, It is possible to always secure a conduction path, and it is possible to improve the fit while maintaining the absorption performance, and the environment where the effect of the powder can be further exhibited in improving the fit when pressure is applied to the diaper from the outside That can be done.

FIGS. 5-8 is an expanded plan view which shows typically the modifications 1-4 of the planar shape of the bag-shaped part T in this embodiment. In addition, since the diaper 20, 30, 40, 50 shown to FIGS. 5-8 shows the characteristic of each bag-shaped part T, let the state which each sheet | seat material laminated | stacked seeing from the outer layer sheet 3 side be an outer shape of a diaper. Show. The bag-shaped portion T is superimposed on the outer shape of the diaper as a region surrounded by a solid line, and the absorber 4 is projected by a one-dot chain line. In addition, the elastic member 9 is omitted except that it is indicated by a solid line.
In the first modification shown in FIG. 5, first, a trunk region 61 extending in the longitudinal direction is formed at the center in the diaper width direction. Since the main line region 61 corresponds to the central portion in the width direction of the crotch which is an excretion region, the particles 6 disposed there can reliably relieve the pressure from the outside. Furthermore, a plurality of side road regions 62 extending in the width direction from side to side with respect to the main line region 61 are formed from the back side R to the ventral side F. Since the particles 6 can reliably move outward in the width direction from the main line area 61 through the left and right side road areas 62, the compression force received in the main line area 61 is surely dispersed in the width direction to appropriately distribute the sheet material. It can be deformed.
In the second modification shown in FIG. 6, a coastal line region 63 extending in the longitudinal direction is formed so as to connect the edge portions in the width direction in the left and right side road regions 62 of the first modification. In the second modified example, in addition to the operation of the first modified example, the particles 6 attracted to the coastal line region 63 can uniformly and strongly deform the sheet material in the vicinity of the elastic band 9 for the diaper leg gathers. It is effective for improving the fit between the thighs.
In the third modification shown in FIG. 7, each side road area 62, 62 arranged at the upper and lower edge in the longitudinal direction of the main line area 61 of the first modification has a long area 64, which is longer in the width direction than the others. 64. Thereby, since particle | grains 6 can move to waist opening part edge Lo vicinity vicinity, it is effective in ensuring the fitting property of the diaper in a stomach circumference, and the leak-proof improvement of excrement.
The fourth modification shown in FIG. 8 has the long region 64 ′ that is wider in the longitudinal direction than that of the third modification. Further, a slightly arcuate coastal line region 63 ′ is formed so as to connect the left and right edge portions in the width direction of the long region 64 ′ and the side road region 62. In addition, this allows the particles 6 to move from the vicinity of the waist opening edge Lo to the side flap right and left side edges in addition to the vicinity of the elastic member 9, so that the fit of the diaper both around the thigh and around the abdomen It is effective for securing the sex and improving the leakage prevention property of excrement.

  The material used for the diaper of each of the above embodiments is not particularly limited, and what is usually applied to this type of article may be used. However, the top sheet is made of a soft material that is liquid-permeable and hits the skin. It is preferable to become. For example, a non-woven fabric made of natural fibers such as cotton or a non-woven fabric made of various synthetic fibers subjected to hydrophilic treatment can be used. The outer layer sheet is preferably made of a liquid-impermeable sheet material. The outer layer sheet may be water vapor permeable as required. Specifically, in order to obtain sufficient water vapor permeability, a film made of synthetic resin such as polyethylene in which fine powder made of a filler such as calcium carbonate is dispersed is stretched and a porous film having fine holes is used. preferable. Examples of the side sheet include a nonwoven fabric, a film sheet, and paper. From the viewpoint of leakage prevention, the side sheet is preferably formed of a liquid non-permeable or hardly permeable hydrophobic nonwoven fabric, a leakage-proof film sheet, or the like. One sheet may be used, or two or more sheets may be combined with a functional sheet. As the material for forming the absorber, those usually used for absorbent articles can be used. Specifically, for example, a fiber assembly or a combination of this and a polymer water-absorbing polymer can be used. As the fibers constituting the fiber assembly, hydrophilic natural fibers such as pulp fibers, synthetic fibers (preferably subjected to hydrophilic treatment), and the like can be used.

  The liquid impermeable sheet is preferably vapor permeable and may or may not be porous. As the material of the sheet, the same material as the back sheet can be suitably used. Specifically, for example, a thermoplastic resin added with an inorganic compound or organic compound filler is melt-extruded from a T die or a circular die to form a film, and then the film is uniaxially or biaxially stretched. The obtained sheet having moisture permeability can be used.

  The wearing article of the present invention is not limited to the unfolded disposable disposable diaper as in the above embodiment, and may be a pants-type or adult diaper, and sanitary shorts. It may be a shorts-type napkin. Moreover, the expansion | deployment type diaper cover used in combination with absorption pads, such as a urine pad, may be sufficient, and the absorber 4 arrange | positioned in the absorption pad also in this case uses the absorption body 4 of the embodiment according to the expansion type diaper. Can be seen as Specifically, the absorbent pad and the diaper cover are mounted in combination so that the absorbent body of the absorbent pad is disposed from the ventral part F to the dorsal part R of the diaper cover via the crotch part C. At this time, the particle | grains 6 arrange | positioned at the crotch part of a diaper cover perform the function similar to what was shown in the said embodiment, and can implement | achieve the ideal fitting property suitable for a wearer's body shape.
