Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is applied to, for example, disposable urine, sanitary napkins, incontinence pads, and the like, and relates to an absorbent product for absorbing and holding body fluid such as urine and a method for producing the absorbent product.
[0002]
[Prior art]
Conventionally, incontinence pads and sanitary napkins as absorbent products are generally pad bodies formed in a rectangular or oval shape that is long in one direction, and are long in the front and back at a position corresponding to the crotch portion of the underwear. By wearing the same direction, excrement such as urine and feces excreted by the user is received.
In such absorbent products, a liquid-impermeable sheet material is applied to the portion that becomes the outer surface when worn by the user, and an absorbent material for absorbing liquid such as urine is arranged on the inside thereof. In addition, a sheet material that allows liquid to pass through is disposed at a location that contacts the user's skin inside.
[0003]
As a result, urine or the like, which is excretion, is prevented from permeating the liquid-permeable sheet material and absorbed by the absorbent material, and further oozing out to the outside by the liquid-impermeable sheet material.
[0004]
[Problems to be solved by the invention]
However, conventional absorbent products such as incontinence pads are unable to follow the shape of the user's lower body with complex irregularities and follow the form. As a result, there was an inconvenience that excreta leaked from the gap.
[0005]
In particular, a widely used incontinence pad or the like employs a so-called crotch gather structure in which both side portions are erected, or a three-dimensional gather structure in which a barrier is further formed on the inside. In this three-dimensional gather, not only the flow of the discharged liquid leaks in the lateral direction but also an absorber is arranged to actively absorb the liquid or the like (Japanese Patent No. 2899273). issue).
However, in such a three-dimensional gather, it is difficult to change the shape so as to fit the front and back curves of the body properly due to the rigidity of the absorber because of the arrangement of the absorber. May become insufficient. For this reason, if a gap is generated, it may cause a lateral leakage of discharged liquid or the like.
[0006]
Therefore, the present invention was discharged by closely fitting the three-dimensional region in which the absorbent body was arranged in the absorbent product such as an incontinence pad and a sanitary napkin corresponding to the complex curve of the user's body. It aims at providing the absorptive product which can prevent that a bodily fluid etc. leaks outside.
[0007]
[Means for Solving the Problems]
  According to the first aspect of the present invention, the back sheet has a shape that is long in one direction and prevents the permeation of liquid, and the liquid permeable surface material disposed on the surface side that contacts the body. And an absorber disposed between the back sheet and the surface material to absorb and hold the liquid that has passed through the surface material, and near both ends in the short direction perpendicular to the longitudinal direction of the product In at least the central region in the longitudinal direction, a three-dimensional region urged in a direction away from the back sheet by the action of an elastic body arranged along the longitudinal direction is formed.The absorber is arranged inside the elastic body, and a plurality of slits are formed along the longitudinal direction of the product so as to extend from the inside to the outside at the side edge portion of the absorber.Achieved with absorbent products.
[0008]
  According to the configuration of the first aspect, the absorbent product of the present invention has a basic shape that is long in one direction by laminating and fixing a plurality of sheet-like materials. The backsheet prevents liquid permeation. The said surface material is a liquid-permeable thing arrange | positioned at the surface side which contacts a body. The absorber is disposed between the back sheet and the surface material to absorb and hold the liquid that has permeated the surface material.
  In the present invention, at least near the both ends in the short direction perpendicular to the longitudinal direction of the product, at least in the central region in the longitudinal direction, that is, on both side portions of the product, by the action of the elastic body arranged along the longitudinal direction. A three-dimensional region urged in a direction away from the back sheet, that is, a three-dimensional structure such as a three-dimensional gather portion is disposed. In addition, in this three-dimensional region, an absorber is arranged not only to stop the flow of the discharged liquid but also to actively absorb the liquid and the like. However, when the absorbent body is disposed, due to its rigidity or the like, when the product is worn, this solid region may not be easily deformed into a shape that fits the body. For this reason, by providing a slit in the absorber of the three-dimensional region, it can be easily deformed by being bent at the location of this slit, and the three-dimensional structure arranged on both side parts of the product is improved by the absorber. It is possible to reliably prevent leakage from the side part.
  Furthermore, the slit becomes a form extending in the short direction of the product, and when the product is mounted, the plurality of slits are deformed little by little, so that the whole is deformed so as to follow the curved surface along the front-rear direction of the body. Easy to make.
[0009]
According to a second aspect of the present invention, in the configuration of the first aspect, the slit is provided in a central region in the longitudinal direction of the product.
According to the configuration of claim 2, the center region of the product in the longitudinal direction (same as the product length direction) is the crotch when the user wears the product in the incontinence pad of the absorbent product. In addition to being a position corresponding to a relatively large region of the body's front-rear curved surface change, it is the site where leakage is most likely to occur. For this reason, a product can be made to fit a body effectively by providing a slit in the absorber of such a location.
[0010]
According to a third aspect of the present invention, in the configuration according to any one of the first and second aspects, the solid region is raised by the action of the elastic body, and the discharge of liquid or the like is prevented inside the solid gather portion. And a barrier portion provided with the absorber and a slit provided in the absorber.
According to the configuration of claim 3, the three-dimensional region may include a three-dimensional gather portion and other barrier configurations, but when the absorber is disposed in a barrier portion other than the three-dimensional gather portion, this absorption A slit can be provided on the body, and even if there is a liquid or the like blocked by the absorber of the barrier portion and blocked by the three-dimensional gather portion, it will return to the absorber and be absorbed as it is.
[0011]
According to a fourth aspect of the present invention, in the configuration according to any one of the first and second aspects, the three-dimensional region is a three-dimensional gather portion that rises by the action of the elastic body, and the absorber and the absorber are provided in the three-dimensional gather portion. And a slit provided in the head.
According to the configuration of claim 4, the three-dimensional area may include a three-dimensional gather portion and other barrier configurations, but when an absorber is disposed in the three-dimensional gather portion itself, a slit is formed in the absorber. Can be provided.
[0012]
The invention according to claim 5 is the structure according to any one of claims 1 to 4, wherein the absorber is a laminate of the same type of absorber or different types of absorbers, and any one of the laminated absorber layers. The slit is formed.
According to the structure of claim 6, when different types of absorbers are combined based on the difference in the functions of the absorbers, the absorbers that are more difficult to deform are stacked so as to be arranged in the three-dimensional region. However, the three-dimensional region can be reliably formed by the slit.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.
[0015]
1 to 4 show an absorbent product according to the first embodiment of the present invention, and an example of the configuration of an incontinence pad is shown. In this embodiment, an example of application to an incontinence pad will be described as a representative of an absorbent product, but it can be applied to sanitary napkins and squeezes with the same structure by slightly changing the overall size. is there. Here, FIG. 1 is a schematic perspective view of the incontinence pad 20 as viewed from the front, and the one labeled “front” in the drawing is the front side of the body when worn (the same applies to other drawings). 2 is a schematic plan view of the incontinence pad 20 of FIG. 1, FIG. 3 is a schematic cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is a schematic cross-sectional view taken along line BB of FIG.
[0016]
As shown in FIG. 1, the incontinence pad 20 has a long shape in the front-rear direction. In the vicinity of both side edges of the incontinence pad 20, three-dimensional gather portions 26, 26 stand up, and serve as a barrier when excreted liquid or the like is about to leak to the side. Side barrier portions 25 and 25 are formed inside the three-dimensional gather portions 26 and 26 (upper side in FIGS. 1 and 3). The three-dimensional gather portions 26 and 26 and the side barrier portions 25 and 25 are three-dimensional regions. Further, a crotch gather portion 31 is provided below the three-dimensional gather portions 26 and 26, and the liquid gathered in close contact with the user's crotch portion and excreted is slightly leaked from the three-dimensional gather portions 26 and 26. Even if it is not leaked to the outside.
[0017]
2 to 4 show detailed structures for forming the above-described portions, and the structure of the incontinence pad 20 will be described in more detail with reference to these drawings. Note that the cross sections shown in FIGS. 2 to 4 are partially shown with a thickness larger than the actual thickness for the convenience of understanding.
As shown in FIG. 3, the center surface material 28 is disposed on the side of the incontinence pad 20 that contacts the user's body. The center surface material 28 has a structure that covers the first absorbent body 23 that is an absorbent body wrapped with a tissue 27.
[0018]
The tissue 27 and the first absorber 23 are portions for absorbing and holding the liquid discharged by the user.
The tissue 23 is a single soft material that absorbs liquid, such as pulp (virgin pulp, recycled recycled paper), rayon, cotton, kenaf, bagasse, silk, and hydrophilic treated fibers (polyolefin, polyester, acrylic), etc. Alternatively, a composite sheet can be used.
The tissue 27 covers the first absorbent layer 23 and prevents a part of the contents from leaking or falling off. As shown in FIGS. 3 and 4, the tissue 27 is displaced from the center in the short direction T. It is overlapped and joined at the part. Thereby, it arrange | positions so that the contraction force of the elastic body 45 mentioned later may not be prevented.
[0019]
Since the center surface material 28 directly touches the user's skin, a material suitable for the center surface material 28 is selected in consideration of a good touch without damaging the skin more than necessary. The center surface material 28 is also called an inner sheet or a top sheet, and as a fiber of a material suitable for allowing a liquid to permeate and a liquid component to permeate quickly, for example, various natural fibers, synthetic fibers or these fibers can be used. You can choose from combinations. For example, as a synthetic fiber, for example, a fiber formed from polyester or polypropylene fiber so as to improve liquid permeability is preferable. For example, when the center surface material 28 is made of a non-woven fabric, for example, a wet non-woven fabric (paper, tissue, hydrospun (Dexter), chemical bond (or resin bond), thermal bond (embossed, air-through), airlaid, span Lace, spunbond, meltblown, needle punch, stitchbond, SM nonwoven fabric (spunbond and meltblown laminate), SMS nonwoven fabric (spunbond and meltblown laminate) The center surface material 28 is particularly preferably a thermal bond, a spunbond, or a spunlace.
[0020]
In this embodiment, the center surface material 28 that is in contact with the user's body is preferably subjected to fine embossing (pin embossing) as indicated by the reference symbol P in FIG. Thereby, the function of rapidly diffusing the liquid that permeates the center surface material 28 toward the first absorber 23 side is exhibited.
[0021]
The first absorbent body 23 has a high retention of the absorbed liquid, and is relatively thin and not bulky. As this 1st absorber 23, the pulp absorber formed by mixing the polymer which is an absorbent material with a pulp, if necessary, for example, or spraying a polymer to a pulp as needed can be used, but especially a pulp etc. The polymer sheet etc. which arrange | positioned the polymer between the sheet materials by high density and made it into a sheet form are preferable. Here, the pulp is a thin one in which, for example, an aggregate of cellulose fibers obtained by mechanically or chemically treating wood is combined slightly densely using, for example, an adhesive. For this reason, the first absorber 23 is relatively hard, rigid, and has a high mold holding property.
In the case where it is not always necessary to increase the amount of absorption of the liquid or the like, the first absorber 23 is excellent in liquid diffusibility, although it has low liquid retention (maintenance of a large volume) and once absorbs. It is also possible to use a non-woven sheet material made of a liquid that is difficult to return to the center surface material side, for example, pulp, rayon, polypropylene, polyethylene, polyester fiber or the like.
[0022]
As shown in FIG. 3, the left and right end regions of the layer in which the first absorbent body 23 is wrapped with the center surface material 28 are raised in the figure by the action of the three-dimensional gather portions 26 and 26 described later. It is supported in the posture. This standing direction is a direction toward the body when the user wears the product. The regions shown standing in FIG. 3 are the side barrier portions 25 and 25 as a part of the three-dimensional region. When the discharged liquid or the like is directed in the lateral direction (direction T in FIG. 2) in a state where the user wears the product, the side barrier portions 25 and 25 pass through the center surface material 28. The first absorbent body 23 is absorbed and held. Therefore, the function of preventing such a liquid from penetrating to the three-dimensional gather portion 26 as much as possible and further absorbing the liquid blocked by the three-dimensional gather portion 26 is exhibited.
In this embodiment, in particular, the vicinity of the outer end in FIG. 3 of the first absorber 23 of the side barrier portions 25, 25, that is, the first absorber 23 near both side edges of the incontinence pad 20 in FIG. 2. By forming the slit 15 in the end edge portion, the side barrier portions 25 and 25 are adapted to closely contact with the curved surface in the front-rear direction of the user's body. The slits 25 and 25 will be described in detail later.
[0023]
In FIG. 3, two side surface materials 29 and 30 are arranged along the side edges of the incontinence pad 20 below the side barrier portions 25 and 25 to provide a three-dimensional gather portion 26.
That is, the side surface materials 29 and 30 are arranged on both sides of the center surface material 28 along the longitudinal direction L (indicated by the direction L in FIG. 2) of the center surface material 28. The center surface material 28 can transmit the liquid, whereas the side surface materials 29 and 30 are made of a material that prevents the liquid from transmitting.
As the material of the side surface materials 29 and 30, for example, a polyolefin nonwoven fabric or a combination of a polyester nonwoven fabric and a thin plastic film, a combination of a polyester nonwoven fabric and a polyethylene film, an SM nonwoven fabric, an SMS nonwoven fabric, or the like is adopted. it can.
[0024]
The left and right three-dimensional gather portions 26 and 26 are formed by disposing the elastic body 17 at least in the center in the longitudinal direction of the side surface materials 29 and 30, respectively. Due to the elastic contraction ability of the elastic body 17, a three-dimensional gather portion 26 is formed in at least the center portion (bag-like folded portion) of each folded side surface material 29, 30 as shown in FIG. . By forming the three-dimensional gather portion 26, the excrement or liquid component of the user is prevented from leaking outside along the short direction (direction perpendicular to the longitudinal direction L in FIG. 2) T of the incontinence pad 20. Block closely to the user's body.
[0025]
In FIG. 3, a second absorber 33 is disposed below the three-dimensional gathers 26 and 26. The second absorbent body 33 is disposed outside the first absorbent body 23 and plays a role of absorbing and holding liquid or the like that cannot be absorbed and held by the first absorbent body 23. For this reason, the 2nd absorber 33 is set as the form with high holding | maintenance of the absorbed liquid, and being comparatively thin and not bulky. As this 2nd absorber 22, although the same thing as the 1st absorber mentioned above is used in this embodiment, you may use the kind of absorber with a different function as mentioned later.
[0026]
The second absorbent body 33 has its lower and both side edges covered with a tissue 34 to prevent dissipation of polymer or the like. And the back seat | sheet 39 is arrange | positioned on the outer side (lower side of FIG. 3). The back sheet 39 is an outer sheet material, and is made of a material that prevents permeation of liquid. As a material of the back sheet 39, for example, a thin plastic film, specifically, a polyethylene film, polyethylene laminated paper, or the like can be used. The back sheet 39 does not allow liquid to pass through, but is preferably selected from a material that can permeate water vapor to prevent stuffiness and has some degree of flexibility. As a result, the contents inside the incontinence pad 20 (solid matter such as filth, urine, blood, etc.) do not leak to the outside.
[0027]
Further, in FIG. 3, crotch gather nonwoven fabrics 32 and 35 are fixed between the tissue 34 and the side surface materials 29 and 30. That is, the crotch gather non-woven fabrics 32 and 35 are arranged and fixed along the longitudinal direction L on both sides of the product in the form of strips. The liquid or the like from one absorber 23 can pass to the second absorber 33 side. Note that the thickness of the opening 41 shown in FIG. 3 is shown for convenience of understanding, and the tissue 27 and the second absorber layer are actually joined.
The outer side edge portions of the crotch gather nonwoven fabrics 32 and 35 are bonded to the side edge portions of the back sheet 39 to form crotch gather portions 31 and 31. That is, for example, string-like elastic bodies 17 and 17 are inserted into the adhesive portions between the outer side edge portions of the crotch gather nonwoven fabrics 32 and 35 and the side edge portions of the backsheet 39, respectively. Similar to the gather portion 26, the gather structure is adopted.
The crotch gather portion 31 cooperates with the three-dimensional gather portion 26 to pull both ends in the short direction corresponding to the crotch of the incontinence pad 20 with an elastic force, thereby improving the fit of the user to the crotch and excretion of the user Demonstrates the function of preventing things or liquid components from leaking from the crotch.
[0028]
Further, an adhesive portion 37 for temporary fixing is provided on the outer surface of the back sheet 39, and the peeled paper 36 is stuck thereon.
Thus, when the incontinence pad 20 is used, the peeling paper 36 is peeled off to expose the displacement preventing adhesive portion 37 so that the displacement preventing adhesive portion 37 is detachably attached to the inner surface of an underwear, for example. Thus, the incontinence pad 20 can be fixed so as not to be displaced with respect to underwear such as pants.
The so-called wing part, in which both end portions in the central region in the longitudinal direction L of the backsheet 39 are further stretched, an adhesive portion is provided on the lower surface thereof, and the stretched portion is folded and fixed to the outer surface of the undergarment. May be provided.
[0029]
Further, in the incontinence pad 20 of the present embodiment, as shown in FIGS. 1 and 3, the first absorber 23 has a predetermined thickness, and therefore, the inner region partitioned by the channel embossed portion 42 is formed. As the convex part 47, it can contact | adhere to the local part of a user's body. Thus, a gap with respect to a local part of the body is not formed as much as possible, and the discharged liquid or the like can be immediately absorbed so as not to leak sideways. In particular, as shown in FIGS. 1 and 2, the convex portion 47 is provided with concave portions 47a and 47b having reduced widths in the vicinity of the center in the longitudinal direction of the incontinence pad 20, and the channel embossed portion 42 is also the same. It is said that the shape. Further, as shown in FIG. 2, correspondingly, the second absorbent body 33 is also provided with reduced concave portions 33a and 33b in the vicinity of the center of the incontinence pad 20 in the longitudinal direction. Yes. For this reason, since the convex part 47 is made to match the shape of the crotch part of a user's body, it fits more appropriately and does not produce a side leak etc.
The channel embossed portion 42 formed around the convex portion 47 is an emboss formed in the shape of a groove having a predetermined width. In this case, a portion where the depth of the groove is deep and a portion where the groove is shallow or no groove is alternated. You may comprise so that it may follow.
[0030]
In addition, the incontinence pad 20 of the present embodiment includes a deformed portion 51 in one end region in the longitudinal direction L of the product in FIG. 2, for example, in the vicinity of the rear end portion of the product in the illustrated case. As shown in FIGS. 3 and 4, the deformable portion 51 is a slit provided in the second absorber 33 with a predetermined width from the vicinity of the end of the second absorber 33 at the rear end of the incontinence pad 20. 46 and 46 are included.
Although the number of the slits 46 and 46 provided in the second absorber 33 may be one, preferably two are provided as illustrated. The first absorber 23 is provided with a notch 43 corresponding to the deformed portion 51.
As a result, when the slit portions 46 and 46 that have received the contraction force of the elastic body 45 bend as shown in FIG. 1, the deformable portion 51 is fixed to the elastic body 45 as shown in FIG. 4. The portion becomes a gently curved surface 51a projecting upward, and the shape gradually expands downward from the gently curved surface 51a, so that a three-dimensional shape that does not easily lose its shape can be formed.
[0031]
FIG. 5 is an explanatory diagram for explaining the configuration and operation of the slit 15 formed in the first absorber 23. The slit 15 is formed on the side edge 23a (see also FIG. 2) of the first absorber 23 so as to extend from the inside of the side edge 23a to the outside. As shown in FIG. 2, a plurality of such slits 15 are preferably formed, and the formation position thereof is preferably near the center in the longitudinal direction L of the incontinence pad 20 as shown in the figure. It is an area.
Specifically, as shown in FIG. 5, each of the slits 15, 15 is formed on the side edge 23 a of the first absorber 23, which is the outer side, from a position in the middle of the product in the drawing that is the inner side of the product. It is formed towards.
The slits 15 and 15 do not have to be cuts that completely cut the first absorber 23, but have a narrow groove shape, or perforations that do not cut the first absorber 13 completely. You may form by the cut | interruption etc. of this.
Thereby, each slit 15 and 15 becomes a form extended in the transversal direction of the incontinence pad 20, and when the user wears the incontinence pad 20, the side surface material 30 side of each slit 15 and 15 is separated from each other. In addition, by gradually deforming, as shown by a curve R in FIG. 5, it is easy to deform along a curved surface along the front-rear direction of the body as a whole.
[0032]
The incontinence pad 20 of the present embodiment is configured as described above. As shown in FIG. 6, the incontinence pad 20 is used for temporary fixing described above at a position corresponding to the inner crotch portion of the underwear PA made of pants, paper diapers, or the like. Are temporarily fixed using an adhesive portion 37 (see FIG. 3).
In this way, the operation when the incontinence pad 20 is mounted will be described with reference to FIG. 7, which shows an enlarged portion where a slit is formed near the left end of the incontinence pad 20 in FIGS. To do.
In FIG. 2, in the vicinity of both ends in the short-side direction T perpendicular to the longitudinal direction L of the incontinence pad 20, that is, on both side portions of the incontinence pad 20, due to the action of each elastic body 17 arranged along the longitudinal direction, In FIG. 3, a three-dimensional gather portion 26 urged in a direction away from the back sheet 39 is disposed.
[0033]
Moreover, the side barrier portions 25 and 25 located inside the three-dimensional gather portions 26 and 26 (upper side in FIG. 3) not only stop the flow of the discharged liquid but also actively absorb the liquid and the like. In addition, a first absorber 23 is arranged. However, when the first absorbent body 23 is disposed, due to its rigidity and the like, when the incontinence pad 20 is worn, the three-dimensional region including the side barrier portions 25 and 25 is deformed into a shape that fits the body. It may be difficult. For this reason, by providing the slits 15, 15 in the first absorber 23, the slits 15, 15 can be bent to be easily deformed.
For this reason, the discharged body fluid leaks out by closely fitting the side barrier portions 25 and 25 in which the first absorbent body 23 is disposed, corresponding to the complex curve of the user's body. Can be effectively prevented

This 3rd absorber 61 forms the convex part 47 shown in FIG.11 and FIG.12, and the convex part 47 of this embodiment respond | corresponds to the difference in a structure of an absorber, 1st Embodiment. It protrudes higher and is formed in a flexible form.
[0040]
The third absorbent body 61 constitutes a part of the absorbent body of the present embodiment, and mainly has a property of retaining the absorbed liquid after rapidly diffusing it. The third absorbent body 61 is referred to as a so-called “mat” material, and is preferably a pulp absorbent body or a polymer formed by mixing a polymer that is an absorbent material with pulp or spraying a polymer onto the pulp, for example. . Here, pulp is an aggregate of cellulose fibers extracted by mechanically or chemically treating wood, for example, and promotes diffusion of absorbed liquid in a state where there are relatively gaps between fibers. The liquid absorption capacity is increased by holding the polymer and increasing the volume in the thickness direction.
[0041]
In FIG. 13, the center surface material 28 covering the upper part of the third absorbent body 61 wrapped in the tissue 34 is extended on both sides to form the three-dimensional gathered portions 126 and 126 via the channel embossed portions 42 and 42. is doing.
In other words, in the three-dimensional gathered portions 126 and 126, the elastic bodies 62 and 62 extending in the length direction of the incontinence pad 60, and the elastic bodies 62 and 62, together with the elastic bodies 62 and 62, are housed and fixed in the bag-shaped portion. And both end portions 23c, 23c of the first absorber 23.
