Detailed Description
< embodiment 1>
Hereinafter, a diaper according to embodiment 1 of the present invention will be described with reference to the drawings. The following embodiments are examples, and the present invention is not limited to these embodiments.
Fig. 1 is an example of a perspective view of a disposable diaper for adult use (hereinafter, simply referred to as "diaper") according to embodiment 1. In a diaper, a direction connecting a front body disposed to face an abdomen of a wearer and a rear body disposed to face a back portion is referred to as a longitudinal direction (also referred to as a front-rear direction). The crotch portion disposed in the crotch (disposed opposite the crotch) of the wearer is disposed between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction). In addition, when the diaper is worn on a wearer, the side facing the skin of the wearer is referred to as the skin surface side, and the opposite side to the skin surface side is referred to as the non-skin surface side. The direction connecting the skin surface side and the non-skin surface side is referred to as a thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is referred to as a width direction (also referred to as a left-right direction). In addition, the thickness direction is defined as a planar view. The diaper 1 has a length along the longitudinal direction and a width along the width direction orthogonal to the longitudinal direction, and is worn on the crotch of a wearer. The term "direction" used in the present application means a direction which coincides with the front, rear, left, and right of the wearer in a state where the diaper 1 is worn on the wearer. For example, in the present application, the term "right-left direction" means a direction which coincides with the right-left direction of the wearer when the diaper 1 is worn on the wearer.
In the present embodiment, as an example of the absorbent article, a pants-type disposable diaper having a tubular structure with a waist opening through which the abdomen of the wearer can be inserted and a pair of left and right leg openings through which the left and right lower limbs of the wearer can be inserted is exemplified. In the present embodiment, a pants-type disposable diaper for adults is exemplified, but the "absorbent article" in the present application is not limited to the pants-type disposable diaper for adults. The term "absorbent article" as used herein includes pants-type disposable diapers for children.
The diaper 1 has: the crotch region 1B is a portion corresponding to a crotch region that covers the pudendum (crotch) of the wearer in a worn state; a front body region 1F, which is a region corresponding to a front body at the waist of the wearer, for covering the abdomen side of the wearer; and a back region 1R, which is a portion corresponding to the back of the waist of the wearer, for covering the back side of the wearer. Here, the front body region 1F is located on the front side of the crotch region 1B, and the rear body region 1R is located on the rear side of the crotch region 1B. Since the diaper 1 in the present embodiment is a pants-type disposable diaper, the left edge of the front body region 1F and the left edge of the rear body region 1R are joined to each other, and the right edge of the front body region 1F and the right edge of the rear body region 1R are joined to each other. Thus, in the diaper 1, the trunk opening 2T (an example of the "waistline opening" in the present disclosure) is formed by the upper edge of the front body region 1F and the upper edge of the back body region 1R. In the diaper 1, a left leg opening 2L is formed in a left portion of the crotch region 1B where the above-described joining is not performed, and a right leg opening 2R is formed in a right portion of the crotch region 1B. When the diaper 1 is worn with the left lower limb of the wearer inserted into the left lower limb opening 2L, the right lower limb of the wearer inserted into the right lower limb opening 2R, and the trunk of the wearer entering the trunk opening 2T, the front body region 1F is disposed on the abdomen side of the wearer, the rear body region 1R is disposed on the back side of the wearer, and the left lower limb opening 2L and the right lower limb opening 2R are fixed to the wearer's body in a state surrounding the thigh of the wearer. Since the diaper 1 is fixed to the body of the wearer in this manner, the wearer can freely move in a state where the diaper 1 is worn. The left lower limb opening 2L and the right lower limb opening 2R are examples of the "two leg hole openings" of the present disclosure.
In the diaper 1, an absorber capable of absorbing and retaining liquid is mainly disposed around the crotch region 1B. In the diaper 1, in order to suppress formation of a gap which is a flow-out path of liquid between the diaper 1 and the skin of the wearer, a three-dimensional gather 3BL is provided in a left leg opening 2L surrounding the thigh of the left leg of the wearer, a three-dimensional gather 3BR (not shown in fig. 1) is provided in a right leg opening 2R surrounding the thigh of the right leg of the wearer, and a waist gather 3R and a abdomen gather 12 are provided in a portion surrounding the abdomen of the wearer. Further, leg gathers 3LF, 3LR (in fig. 1, leg gathers 3LR are not shown) are provided at positions surrounding the root portions of the legs of the wearer. Further, the leg gathers 3LF are provided in the front body region 1F, and the leg gathers 3LR are provided in the rear body region 1R. In fig. 1, only the leg gathers 3LF are illustrated. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R are contracted by the elastic force of the stretchable member, and are thereby brought into close contact with the skin of the wearer. Further, the leg gathers 3LF, 3LR prevent the occurrence of gaps between the root portions of the legs of the wearer and the diaper 1. Thus, the discharged liquid discharged from the pudendum of the wearer is absorbed by the absorber of the diaper 1 almost without leaking out from the diaper 1.
The diaper 1 can be used in combination with an inner pad, not shown. The inner pad is a substantially rectangular absorbent article provided with an absorber, and absorbs discharged liquid of a wearer. When the diaper 1 and the inner pad are used in combination, the inner pad is placed on the skin surface side of the diaper 1 so as to abut on the discharge hole of the wearer. The discharged liquid is first absorbed by the inner pad, and only the discharged liquid that has not been absorbed by the inner pad reaches the absorber of the diaper 1 and is further absorbed. Thus, even when the amount of discharged liquid is large, leakage of discharged liquid from the diaper 1 can be prevented. In addition, when the amount of discharged liquid is small and the discharged liquid can be absorbed by the inner pad, only the inner pad needs to be replaced even if the discharged liquid is discharged, so that the intervention cost can be reduced. In addition, the frequency of changing the diaper 1 can be reduced, and the diaper 1 can be used for a long period of time.
Fig. 2 is an example of an exploded perspective view of the diaper 1 according to embodiment 1. The diaper 1 has a cover sheet (an example of an "outer cover sheet" of the present disclosure) 4 and an inner cover sheet 5. The cover sheet 4 and the inner cover sheet 5 are substantially hourglass-shaped (gourd-shaped) sheets bonded together to form the outer surface of the diaper 1, and are substantially the same shape and substantially the same size except for the front region 1F-side end and the rear region 1R-side end. In a state of being worn on a wearer, the cover sheet 4 is laminated on the non-skin surface side of the wearer, and the inner cover sheet 5 is laminated on the skin surface side of the wearer. Between the cover sheet 4 and the inner cover sheet 5, stretchable members for forming the waist gathers 3R, the abdomen gathers 12, and the leg gathers 3LF, 3LR are provided. In the present embodiment, linear rubber is used as the expansion and contraction member. Further, as the expansion and contraction member, a belt-shaped expansion and contraction member such as rubber can be appropriately selected instead of the linear rubber.
For example, nonwoven fabrics made of a liquid impermeable thermoplastic resin may be used as the material of the cover sheet 4 and the inner cover sheet 5 in order to suppress leakage of discharged materials. Here, examples of the liquid-impermeable thermoplastic resin include Polyethylene (PE) and polypropylene (PP). Hereinafter, the absorber 8 and the back sheet 6, the top sheet 9, and the side sheets 10L, 10R are sometimes combined with each other to form an inner body, and the cover sheet 4 and the inner cover sheet 5 each provided with a linear rubber are sometimes referred to as an outer body (an example of an "outer body" in the present disclosure) as a concept corresponding to the inner body.
The diaper 1 has a back sheet 6, an absorber 8, and a top sheet 9 laminated in this order on the wearer-side surfaces of the cover sheet 4 and the inner cover sheet 5. The back sheet 6 is a substantially rectangular sheet having a length extending from the front body to the rear body of the wearer through the crotch in the longitudinal direction and a predetermined width in the width direction perpendicular to the longitudinal direction. The absorber 8 and the top sheet 9 are sheet-like members having a substantially rectangular appearance like the back sheet 6, and are sequentially laminated on the back sheet 6 in a state where the longitudinal direction matches the longitudinal direction of the back sheet 6. The back sheet 6 is a sheet made of a liquid impermeable thermoplastic resin for suppressing leakage of discharged material. Further, the back sheet 6 is provided with minute holes. The holes are both liquid-permeable and breathable. The holes are provided, for example, in the region overlapping the absorber 8. The top sheet 9 is a sheet-like member disposed on the skin surface side of the wearer so as to cover the water absorption surface of the absorber 8. The top sheet 9 has liquid permeability in part or all of it. Thus, in a state in which the diaper 1 is worn, liquid discharged from the wearer is immersed in the absorbent body 8 through the topsheet 9 which may come into contact with the skin of the wearer, and is absorbed therein. Examples of the liquid-permeable sheet include woven fabrics, nonwoven fabrics, and porous films. In addition, the top sheet 9 may have hydrophilicity.
The absorber 8 has an absorbent core 8c and a core wrap sheet 7 (water permeable sheet) that wraps the absorbent core 8 c. The absorbent core 8c is of a substantially hourglass shape with narrowed portions. The absorbent core 8c has a structure in which a particulate absorbent resin (high molecular absorbent material) such as SAP (super absorbent polymer: super Absorbent Polymer) which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water is held in the interstices of a short fiber of cellulose fibers such as pulp fibers, rayon fibers or cotton fibers, or a short fiber obtained by hydrophilizing a synthetic fiber such as polyethylene, polypropylene or polyethylene terephthalate. When the absorbent core 8c absorbs liquid discharged from the wearer, the absorbent resin in the gaps held in the short fibers is swelled, and the liquid is held in the short fibers. In the present embodiment, the absorbent core 8c is substantially hourglass-shaped with a narrowed central portion. The absorbent core 8c can take an appropriate shape according to the purpose. Examples of the shape of the absorbent core 8c include a rectangular shape, an elliptical shape, and various other shapes. In the present embodiment, the absorbent core 8c is formed of 1 pad, but the absorbent core 8c may be formed by stacking a plurality of pads.
The core wrap sheet 7 is a thin liquid-permeable sheet, and by wrapping the absorbent core 8c with the core wrap sheet 7, the SAP of the absorbent core 8c is less likely to be mixed into other structures. In addition, the absorbent core 8c is suppressed from running out. The core wrap sheet 7 can be formed of pulp fibers, and as an example, a tissue can be used. The core wrap sheet 7 may be 1 sheet, but may be composed of 2 sheets, that is, an upper sheet disposed on the skin side of the wearer and a lower sheet disposed on the non-skin side of the wearer and wound around the side surface of the absorbent core 8c and the skin side. When the core wrap sheet 7 is formed of 2 sheets, the width direction end portion of the upper side sheet may be covered with another sheet (for example, side sheets 10L and 10R, back sheet 6, and top sheet 9 described later). The absorbent body 8 is enclosed by the back sheet 6 and the top sheet 9, and the sample can be prevented from being removed by these sheets, so that the core wrap sheet 7 may not be provided.
The back sheet 6, the absorber 8, and the top sheet 9 all extend from the front body region 1F to the back body region 1R. Thus, when the back sheet 6, the absorber 8, and the top sheet 9 are laminated to cover the wearer's pudendum (crotch), the respective longitudinal ends of the back sheet 6, the absorber 8, and the top sheet 9 are positioned on the wearer's abdomen side and back side. That is, the pudendum of the wearer is covered with the absorber 8 from the abdomen side to the back side of the wearer. Therefore, regardless of the posture of the wearer in which the wearer is facing the abdomen down and the posture of the wearer in which the wearer is facing the back down, the discharged liquid is discharged outside the body, and the discharged liquid is brought into contact with the absorber 8 via the top sheet 9.
Further, a linear rubber 4F7 (an example of the "2 nd stretchable member" in the present disclosure) is provided between the back sheet 6 and the core wrap sheet 7 at the widthwise central portion in an elongated state in the longitudinal direction from the front body region 1F to the crotch region 1B. The linear rubber 4F7 is bonded to the back sheet 6, and is bonded to the inner cover sheet 5 and the cover sheet 4 via the back sheet 6. The linear rubber 4F7 exerts a force that contracts the inner cover sheet 5 and the cover sheet 4 in the longitudinal direction. The region where the linear rubber 4F7 is provided is preferably a region where the absorber 8 and the inner cover sheet 5 are not bonded, but may be a region where the absorber 8 and the inner cover sheet 5 are bonded. The linear rubber 4F7 may be provided between the cover sheet 4 and the inner cover sheet 5.
Further, a linear rubber cover piece 13 (telescopic member cover piece) is arranged on the skin surface side of the linear rubber 4F 7. The linear rubber cover sheet 13 is adhered to the back sheet 6 while covering the linear rubber 4F7 from the skin surface side. The linear rubber cover sheet 13 is disposed between the linear rubber 4F7 and the absorber 8. The whole of the linear rubber cover sheet 13 is not bonded to the core wrap sheet 7 of the absorber 8. The linear rubber cover sheet 13 is disposed between the absorber 8 and the backsheet 6, is bonded to the backsheet 6, and is partially non-bonded to the core wrap sheet 7 of the absorber 8. This prevents the elastic force (contraction force) of the linear rubber 4F7 from being excessively applied to the absorber 8, and prevents the absorber 8 from being excessively deformed. In addition, when a band-shaped stretchable member is used instead of the linear rubber 4F7, the stretchable member and the core wrap 7 can be made non-adhesive at a part thereof without providing the linear rubber cover sheet 13. In the present embodiment, the linear rubber cover sheet 13 is formed to have the same length as the back sheet 6. The linear rubber cover sheet 13 may be formed to have a length corresponding to the extension region of the linear rubber 4F7, or may be formed to be longer than the extension region of the linear rubber 4F7 and shorter than the back sheet 6. Further, a part of the linear rubber cover sheet 13 is not bonded to the absorber 8. The linear rubber cover sheet 13 may be non-bonded to the absorber 8 as a whole.
The diaper 1 has elongated belt-shaped side panels 10L and 10R for forming the above-described three-dimensional gathers 3BL and 3BR. The side sheets 10L and 10R are provided on the long side of the top sheet 9. The linear rubbers 10L1 and 10R1 are bonded to the side sheets 10L and 10R in a state of being elongated in the longitudinal direction. Thus, when the edge 4F4 of the cover sheet 4 which is the left edge of the front body region 1F and the edge 4R4 which is the left edge of the rear body region 1R are joined to each other, and the edge 4F5 of the cover sheet 4 which is the right edge of the front body region 1F and the edge 4R5 which is the right edge of the rear body region 1R are joined to each other, the side sheets 10L and 10R are pulled up in the longitudinal direction by the contraction force of the linear rubbers 10L1 and 10R1, and stand up from the top sheet 9 along the folding lines 10L2 and 10R2, as shown in fig. 1, the diaper 1 is completed. As a result, three-dimensional gathers 3BL, 3BR are formed which prevent liquid from flowing out of the left and right lower limb openings 2L, 2R.
Here, regarding the side sheets 10L, 10R, when the three-dimensional gathers 3BL, 3BR are formed, the interval in the width direction between the standing lines of the three-dimensional gathers 3BL, 3BR is set to such an extent that the inner pad enters. The bonding method of the edge 4F4 and the edge 4R4, and the edge 4F5 and the edge 4R5 is not particularly limited, but can be performed by, for example, heat sealing, high-frequency sealing, ultrasonic sealing, or the like.
The diaper 1 further includes an end sheet 11F that is laminated on the wearer side surface in the front region 1F of the cover sheet 4, and an end sheet 11R that is laminated on the wearer side surface in the back region 1R of the cover sheet 4, with the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R interposed therebetween. The end sheets 11F and 11R are long sheets that overlap the cover sheet 4 and the inner cover sheet 5 at one end side in the longitudinal direction of the top sheet 9. The end pieces 11F, 11R are non-water-impermeable nonwoven fabrics, and reinforce the cover piece 4 and the inner cover piece 5 mainly at the waist abutment portion of the diaper 1. The end pieces 11F and 11R are coated with an adhesive, and bonded to the inner cover piece 5 by the adhesive. The end sheets 11F, 11R are laminated on the skin surface side of the laminate formed by the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R, and the end portions of the laminate are prevented from being in direct contact with the skin surface to give the wearer a feeling of discomfort.
Fig. 3A and 3B are examples of diagrams schematically showing a state in which the diaper 1 according to the embodiment is developed and extended. Fig. 3A schematically shows an internal configuration of the diaper 1 in a developed and elongated state when viewed from the left side. Fig. 3B is a plan view of the diaper 1 in an unfolded and extended state.
As shown in fig. 3B, the linear rubber 4F3 forming the leg gathers 3LF is provided along the edges of the front body region 1F side of the right and left lower limb openings 2R and 2L into which the legs of the wearer enter when the diaper 1 is assembled. The linear rubber 4F3 is bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state. The linear rubber 4F3 is disposed in the crotch region 1B on the front side so as to cross in the lateral direction. At the portion where the linear rubber 4F3 is provided so as to traverse in the left-right direction in this way, the linear rubber 4F3 and the absorber 8 overlap in the thickness direction of the diaper 1. The widthwise central portion of such a transverse region is a region corresponding to the urethral orifice of the wearer when the diaper 1 is worn. In the region overlapping the absorber 8 in the thickness direction, the arrangement of the linear rubber 4F3 is not limited to the crossing as shown in fig. 3B. The linear rubber 4F3 may have a component in the width direction, and the component in the width direction in the extending direction of the linear rubber 4F3 may be preferably larger than the component in the length direction.
On the other hand, the linear rubber 4R3 (an example of the "1 st stretchable member" of the present disclosure) forming the leg gathers 3LR is provided along the edges of the rear body region 1R side of the right and left lower limb openings 2R and 2L. The linear rubber 4R3 is bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state. In the crotch region 1B on the rear body side, the tip end portion of the linear rubber 4R3 faces the width direction. However, the linear rubber 4R3 is cut at the center in the width direction, and the left linear rubber 4R3 and the right linear rubber 4R3 are not connected.
The inner cover sheet 5 and the absorber 8 are appropriately bonded by an adhesive through the back sheet 6 from the front region 1F to the back region 1R. However, as shown in fig. 3B, in the region where the linear rubber 4F3 crosses in the precursor region 1F, the inner cover sheet 5 and the absorber 8 are non-bonded (set as a non-bonded region 15). In fact, in the non-bonded region 15, the inner cover sheet 5 and the back sheet 6 are non-bonded. In the present embodiment, the non-adhesive region 15 is provided over the entire overlapping region of the crotch region 1B where the linear rubber 4F3 and the absorber 8 overlap.
As shown in fig. 3B, the linear rubber 4F7 is provided in a central portion in the width direction between the back sheet 6 and the core wrap sheet 7 in a state extending in the longitudinal direction from the front body region 1F to the crotch region 1B. In practice, the linear rubber 4F7 is provided between the back sheet 6 and the linear rubber cover sheet 13 (not shown in fig. 3B). Further, the side of the crotch region 1B than the linear rubber 4F7 corresponds to the anus of the wearer when the diaper 1 is worn by the wearer. The absorber 8 is extruded in a linear shape so as to surround the linear rubber 4F7, and is shown as a line 14 in fig. 3B. The line 14 is provided at the end portion on the crotch region 1B side in the width direction. The wire 14 is bent outward in the width direction at the end on the front body region 1F side. Such pressing of the absorber 8 is achieved by embossing with a roller, for example.
The cover sheet 4 is folded back at one end side at the folding lines 4FF and 4RF shown in fig. 2. The above-described waist gather 3R is formed by bonding a linear rubber (linear rubber) 4F1 in an elongated state to the front region 1F of the cover sheet 4 and bonding a linear rubber (linear rubber) 4R1 in an elongated state to the rear region 1R of the cover sheet 4. The linear rubbers 4F1 and 4F2 are provided in the order of the linear rubbers 4F1 and 4F2 from the side of the folding line 4FF along the folding line 4FF that forms the upper edge of the precursor region 1F when folded back. Similarly, the abdominal gathers 12 are formed by bonding the linear rubber 4F2 in an elongated state in the front region 1F of the cover sheet 4 and bonding the linear rubber 4R2 in an elongated state in the rear region 1R of the cover sheet 4. The linear rubbers 4R1 and 4R2 are also provided in the order of the linear rubbers 4R1 and 4R2 from the side of the folded-back line 4RF along the folded-back line 4RF that forms the upper edge of the rear body region 1R when folded back, as with the linear rubbers 4F1 and 4F 2.
Thus, the linear rubbers 4F1, 4F2 are provided on the cover sheet 4 in such an orientation that the longitudinal direction, which is the expansion and contraction direction, is the lateral direction of the diaper 1. The linear rubbers 4R1, 4R2 are provided on the cover sheet 4 in such a manner that the longitudinal direction, which is the extension and contraction direction, is the lateral direction of the diaper 1. Thus, when the edge 4F4 and the edge 4R4 are joined to each other and the edge 4F5 and the edge 4R5 are joined to each other, the linear rubbers 4F1, 4F2 and the linear rubbers 4R1, 4R2 form a substantially annular stretchable member surrounding along the trunk opening 2T, and function to shrink the trunk opening 2T in the trunk-surrounding direction. That is, the linear rubbers 4F1 and 4F2 and the linear rubbers 4R1 and 4R2 exert a contraction force to bring the diaper 1 into close contact with the wearer, thereby preventing a gap from being formed between the diaper 1 and the abdominal circumference of the wearer. The linear rubber 4F2 and the linear rubber 4R2 overlap the absorber 8 at a portion on the crotch region 1B side thereof.
The linear rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along portions that are upper edges of the front body region 1F and the rear body region 1R shown in fig. 1. The linear rubbers 4F2 and 4R2 are disposed in parallel with a predetermined interval therebetween. The linear rubbers 4F1 and 4R1 fasten the abdomen of the wearer relatively strongly above the linear rubbers 4F2 and 4R2 in a state where the diaper 1 is worn. The linear rubbers 4F1 and 4R1 serve to prevent the diaper 1 from being brought into close contact with the wearer, thereby preventing the wearing position from being shifted, and preventing discharged liquid from leaking from the abdomen and back. The linear rubbers 4F2 and 4R2 alleviate the sense of compression to the wearer caused by the contraction force of the linear rubbers 4F1 and 4R 1.
The cover sheet 4 is folded back at the folding lines 4FF and 4RF to extend to the arrangement regions of the linear rubbers 4F1 and 4R1, and the arrangement regions of the linear rubbers 4F1 and 4R1 are reinforced by the folded back portions. The end pieces 11F and 11R (see fig. 2) are provided in the arrangement regions of the linear rubbers 4F2 and 4R2 where the cover piece 4 after being folded back at the folding lines 4FF and 4RF is not extended, and the arrangement regions of the linear rubbers 4F2 and 4R2 are reinforced.
In the present application, the state in which the sheets overlap is not limited to the manner in which the sheets that overlap each other in a state in which the sheets are in full contact with each other, and is a concept including the manner in which a part of the sheets overlap each other. For example, a portion of the end piece 11F on one end side in the longitudinal direction of the back piece 6 overlaps with a portion of the cover piece 4 in a contact state. In the diaper 1, the cover sheet 4, the end sheets 11F, 11R, the inner cover sheet 5, and the side sheets 10L, 10R are stacked in addition to the back sheet 6 and the top sheet 9 sandwiching the absorber 8, and therefore, it can be said that a laminate in which these multiple sheets are stacked is provided.
The line 14 formed in the absorber 8 will be described with reference to fig. 4 to 6. Fig. 4 is a plan view showing the absorbent body 8, a part of the linear rubbers 4F3, 4R3, and the linear rubber 4F7 drawn out from the diaper 1. Fig. 5 is a cross-sectional view of the diaper 1 taken along the V-V line in fig. 3B in the width direction. Fig. 6 is a cross-sectional view of the diaper 1 taken at the line VI-VI in fig. 3B in the width direction.
As shown in fig. 4, the wire 14 has 5 slots. The 5 grooves are constituted by grooves 14AL, 14AR, grooves 14BL, 14BR (an example of the "1 st groove" of the present disclosure), and groove 14C (an example of the "high rigidity portion" of the present disclosure). The grooves 14AL, 14AR are a pair of left and right grooves formed in the absorber 8 and extending from the crotch region 1B toward the front body region 1F side end in the region corresponding to the groin of the wearer from the widthwise center of the diaper 1 toward the outside. The grooves 14AL, 14AR are pressing grooves formed by pressing the absorber 8. The grooves 14AL and 14AR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14AL, 14AR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. The absorber 8 is folded along the groin of the wearer by forming the grooves 14AL, 14 AR.
In addition, when the areas where the grooves 14AL, 14AR are provided in plan view, a non-adhesive area 15 is formed which is provided so as to include the areas overlapping the grooves 14AL, 14AR, and in which the absorber 8 and the inner cover sheet 5 are non-adhesive. In fig. 4, the non-adhesive region 15 is shown with a ground pattern. If the non-adhesive region 15 is formed so as not to include the region overlapping the grooves 14AL, 14AR, and the absorber 8 is adhered to the inner cover sheet 5 in this region, the outer body is expanded to be in contact with the skin side, and as a result, the state of the outer body is transmitted to the absorber 8, and a force approaching from a state of bending along the inguinal portion to a flat state acts on the absorber. In contrast, the diaper 1 according to the present embodiment is configured as described above, and the absorber 8 in a state of being folded along the groin portion can be held in a folded state and can be abutted against the skin surface side. This improves the close contact between the absorbent body 8 and the skin of the wearer in the diaper 1.
As shown in fig. 4, the non-adhesive region 15 extends in the width direction of the diaper 1 and has a substantially rectangular shape. In the wearing state of the diaper 1, the absorber 8 can be pushed up to the skin surface side by the outer body in a state where the outer body is pulled in the left-right direction, and the absorber 8 can be brought into contact with the skin surface of the wearer. This improves the close contact between the absorbent body 8 and the skin of the wearer in the diaper 1.
In the case of the diaper 1 as seen in plan view as shown in fig. 4, the diaper 1 includes the linear rubber 4F3 bonded to the inner cover sheet 5 and the cover sheet 4 in an elongated state in the region overlapping the unbonded region 15. As shown in fig. 3B, the end portions of the linear rubber 4F3 are disposed at the width-direction end portions of the left and right lower limb openings 2L and 2R. By inserting the legs into the left and right lower limb openings 2L, 2R provided in the outer body, the outer body is pulled in the widthwise outer direction, and the linear rubber 4F3 is also pulled in the widthwise outer direction. In this way, in the region extending in the width direction across the crotch region 1B of the linear rubber 4F3, the outer body is lifted up toward the skin surface side, but in this region, a non-adhesive region 15 where the absorber 8 and the outer body are non-adhesive is provided. Thus, the absorber 8 is lifted up by the outer body so as to approach the skin surface side while being kept in a state of being bent along the groin portion. In the present embodiment, the linear rubber 4F3 for forming leg gathers extends in the non-bonded region 15 and is connected to the left and right, but the linear rubber provided in the non-bonded region 15 and crossing the crotch region 1B and the linear rubber for forming leg gathers may be provided. The end portions of the linear rubber 4F3 may be bonded to the outer body, and the linear rubber may be bonded to another sheet disposed between the outer body and the back sheet in the non-bonding region 15 which is the widthwise central portion. Even with such a configuration, if the backsheet and the separate sheet are non-bonded in the non-bonded region 15, the diaper 1 can obtain the above-described effects.
Next, the grooves 14BL, 14BR will be described. The grooves 14BL and 14BR are a pair of left and right grooves formed in the absorber 8 and extending in the longitudinal direction in the region corresponding to the urethral orifice of the wearer. The grooves 14BL, 14BR are pressing grooves formed by pressing the absorber 8. The grooves 14BL, 14BR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14BL, 14BR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. The absorber 8 has grooves 14BL and 14BR formed therein, so that the absorber 8 between the grooves is in a state of bulging toward the urethral orifice side. Thus, the diaper 1 can bring the absorber 8 into contact with the urethral opening, and thus can improve the adhesion of the absorber 8 to the skin of the wearer.
The linear rubber 4F3 is disposed so as to include a region overlapping the precursor regions 1F of the grooves 14BL and 14BR when viewed in plan. With this configuration, the effect of bringing the absorber 8 into contact with the skin surface side of the wearer in a folded state by the linear rubber 4F3 is improved. This is because: by providing the non-adhesive region 15 in the region where the linear rubber 4F3 and the absorber 8 overlap, the absorber 8 is not deformed by contraction of the linear rubber 4F3, and the absorber 8 having a shape bent by the grooves 14BL and 14BR can be brought into contact with the skin side. In order to achieve this effect, it is preferable that the linear rubber 4F3 is pulled in the left-right direction in a state in which the legs are inserted into the left and right lower limb openings 2L, 2R, and thereby the absorber 8 is brought into contact with the skin. Therefore, the linear rubber 4F3 is preferably a linear rubber for forming leg gathers, in which the end portions are disposed at the end portions in the width direction of the diaper 1. When the linear rubber 4F3 for forming leg gathers overlaps the grooves 14AL, 14AR as viewed in the thickness direction, the absorbent body 8 folded along the groin portion is preferably brought into contact with the skin surface side of the wearer by the contraction force of the linear rubber 4F 3. When the linear rubber 4F3 for forming leg gathers overlaps the grooves 14BL and 14BR as viewed in the thickness direction, the absorbent body 8 is preferably placed against the urethral orifice or an inner pad (urine pad) disposed on the top sheet 9 is preferably placed against the urethral orifice. The diaper 1 may be configured as follows: the linear rubber 4F3 is overlapped with the grooves 14AL, 14AR, and the linear rubber 4F3 is not overlapped with the grooves 14BL, 14BR, whereby the absorber 8 bent along the groin portion is suitably abutted against the skin surface side of the wearer by the contraction force of the linear rubber 4F 3. The diaper 1 may be configured as follows: the linear rubber 4F3 does not overlap the grooves 14AL, 14AR, and the linear rubber 4F3 overlaps the grooves 14BL, 14BR, so that if the linear rubber 4F3 for forming leg gathers overlaps the grooves 14BL, 14BR, the absorbent body 8 is preferably brought into contact with the urethral orifice or the inner pad (diaper) disposed on the top sheet 9 is brought into contact with the urethral orifice. As in the present embodiment, the diaper 1 may be configured such that the linear rubber 4F3 overlaps the grooves 14AL and 14AR and the grooves 14BL and 14BR, and both of the above-described 2 suitable configurations may be adopted.
The grooves 14AL, 14AR and the grooves 14BL, 14BR are not limited to extrusion grooves. The grooves 14AL, 14AR and the grooves 14BL, 14BR may be formed by reducing the pulp order of the absorbent core 8c only in the groove forming portion, so long as the absorbent body 8 can be folded with the grooves as the starting points. In addition, by making the grooves 14AL, 14AR and the grooves 14BL, 14BR as extrusion grooves, the groove forming portion can be made highly rigid, and the deformation of the groove forming portion can be prevented.
In the present embodiment, the groove 14AL is connected to the groove 14BL, and the groove 14AR is connected to the groove 14 BR. Thereby, the grooves 14AL and 14BL, and the grooves 14AR and 14BR can be integrally formed. The grooves 14AL and 14BL may be adjacent to each other with a space therebetween, and the grooves 14AR and 14BR may be adjacent to each other with a space therebetween. In the case where the grooves are spaced apart from each other, the end of the groove 14BL may not be disposed on the extension line of the groove 14AL, or the end of the groove 14BR may not be disposed on the extension line of the groove 14 AR.
The non-adhesive region 15 includes a region overlapping the end of the grooves 14BL, 14BR on the precursor region 1F side in plan view. By inserting the legs into the left and right lower limb openings 2L, 2R provided in the outer body, the outer body is pulled in the widthwise outer direction, and the linear rubber 4F3 is also pulled in the widthwise outer direction. In this way, in the region extending in the width direction across the crotch region 1B of the linear rubber 4F3, the outer body is lifted up toward the skin surface side, but a non-adhesive region 15 is provided in which the absorber 8 and the outer body are non-adhesive. Thus, the absorber 8 is pushed up by the outer body so as to approach the urethral orifice while being held in a state of being raised toward the urethral orifice between the grooves 14BL, 14 BR. In this way, the diaper 1 can bring the absorber 8 into contact with the urethral orifice, and therefore, the adhesion of the absorber 8 to the skin of the wearer can be improved.
Next, the tank 14C will be described. The groove 14C is formed in the absorber 8, is disposed on the rear body region 1R side of the grooves 14BL, 14BR, and extends in the width direction. The groove 14C is a pressing groove formed by pressing the absorber 8. The grooves 14C may be formed by pressing only the absorbent core 8C, or may be formed by pressing the absorbent body 8 including the core wrap sheet 7. In the present embodiment, the grooves 14C are formed by pressing the core wrap sheet 7 and the absorbent core 8C from the skin surface side. May be provided near the end of the grooves 14BL, 14BR on the rear region 1R side (for example, on the front region 1F side of the end). The groove 14C may be disposed near the rear region 1R side end of the grooves 14BL, 14 BR.
The groove 14C is a pressing groove, and therefore becomes a high-rigidity portion as compared with the outside of the groove forming region. Further, since the grooves 14BL and 14BR are formed in the diaper 1, the absorber 8 is narrowed in the right-left direction by the legs of the wearer in the wearing state, and the absorber 8 is folded so as to protrude toward the skin from the grooves 14BL and 14BR, thereby improving the adhesion to the urethral meatus. However, if the portion of the absorber 8 protruding toward the skin from the grooves 14BL, 14BR extends to the anus of the wearer, the absorber 8 protrudes toward the anus and the absorber 8 enters the gluteal and femoral cleft (fissure) of the buttocks, which may cause discomfort to the wearer. If the absorber 8 enters the cleft of the buttocks, the feces discharged from the anus is pushed up to the skin surface side by the absorber 8, and the feces may collide with the skin. Therefore, the absorber 8 protrudes toward the anus and the absorber 8 enters the gluteal cleft of the buttocks, which is undesirable.
In order to suppress the occurrence of this problem, the diaper 1 according to the present embodiment is formed with the grooves 14C. By providing the diaper 1 with the groove 14C, the absorber 8 can be prevented from protruding toward the skin side in the area of the diaper 1 corresponding to the anus. The diaper 1 is provided with the groove 14C, which is a highly rigid portion extending in the left-right direction in the area corresponding to the anus, thereby forming a space between the anus, the gluteus and thigh, and the absorber 8, and suppressing the occurrence of the above-described problem. In fig. 4, the area corresponding to the anus (anus-corresponding area) 30 is an area where the anus of the wearer is located in the wearing state of the diaper 1.
The grooves 14BL and 14BR can bend the absorber 8 in a W shape when the absorber is cut in the width direction, and can bring the skin surface side of the absorber 8 into abutment with the urethral orifice. If the grooves 14BL and 14BR are provided only in the region corresponding to the urethral orifice, and the absorber 8 is formed in a planar shape in a portion other than the groove forming region, the grooves do not function as bending means of the absorber 8. Thus, the groove needs to be extended longer than the region corresponding to the urethral orifice. Thus, in the present embodiment, the pair of right and left slits 14BL, 14BR extending in the longitudinal direction of the diaper 1 extend from the region corresponding to the urethral orifice on the abdomen side to the region corresponding to the anus 30 on the back side. The anus corresponding region 30 is a region where the anus of the wearer is located in the wearing state of the diaper 1. The diaper 1 according to the present embodiment can improve the close contact between the absorber 8 and the wearer's urethral opening by extending the grooves 14BL and 14BR to the anus corresponding region 30 and bending the absorber 8 in a W shape. However, if the grooves 14BL, 14BR are formed in the anus corresponding region 30, and the absorber 8 is bent along the grooves 14BL, 14BR, the absorber 8 may be caught in the cleft (fissure) of the buttocks of the wearer. If the absorber is caught in the gluteal cleft of the wearer, the wearer feels a sense of compression, and the feces discharged from the wearer will come into contact with the skin surface around the gluteal cleft, and the sense of wearing will be reduced. Then, the diaper 1 according to the present embodiment includes the groove 14C. In this way, the diaper 1 prevents the absorber 8 from sinking into the gluteal cleft of the wearer by suppressing the absorber 8 of the anus corresponding region 30 from bending along the grooves 14BL, 14BR, and can suppress the deterioration of the wearing feeling.
In the present embodiment, since the grooves 14BL and 14BR are also extrusion grooves, the grooves 14BL, 14BR and the groove 14C can be formed in the same step. In addition, the tank 14C may be connected to the tanks 14BL, 14 BR. Thereby, the grooves 14BL, 14BR and the groove 14C can be integrally formed. In addition, even if the groove 14C is connected to the grooves 14BL, 14BR, the absorber 8 bulges toward the skin side between the grooves 14BL, 14BR, but the absorber 8 is suppressed from bulging in the formation region of the groove 14C as the back side thereof. The grooves 14BL and 14BR are disposed on the front body region 1F side of a region corresponding to the anus of the wearer (anus corresponding region 30). This makes it possible to suppress the protrusion of the absorber 8 in the area corresponding to the anus (anus corresponding area 30) of the diaper 1.
The diaper 1 further includes a linear rubber 4F7 bonded in an elongated state in the longitudinal direction to the non-skin surface side of the absorber 8. The linear rubber 4F7 is disposed in a region overlapping between the pair of grooves 14BL, 14BR, and stretches in the longitudinal direction. The linear rubber 4F7 contracts the inner cover sheet 5 and the cover sheet 4 as the outer body, and pushes up the absorber 8 toward the skin surface side. Thus, the diaper 1 can lift the portion of the absorber 8 protruding toward the urethral orifice side between the pair of grooves 14BL, 14BR toward the skin surface side by the outer body. Since the diaper 1 can bring the absorber 8 into contact with the urethral orifice, the adhesion of the absorber 8 to the skin of the wearer can be improved.
The linear rubber 4F7 extends between the pair of left and right grooves 14AL, 14AR when the diaper 1 is viewed in plan. In the region where the absorber 8 is folded around the grooves 14AL, 14AR as the starting points and is in a state of being along the groin portion, the outer body is contracted in the longitudinal direction, and is in a state of being lifted to the non-skin side, and is easily deformed along the root portion of the leg. This can improve the wearing feeling of the diaper 1.
As described above, the linear rubber 4F7 extends between the grooves 14AL, 14AR and between the grooves 14BL, 14 BR. As shown in fig. 3B, the linear rubber 4F7 is not overlapped with the linear rubber 4F2 for abdominal puckering in the state where the diaper 1 is viewed in plan. With this structure, the diaper 1 forms a space between the crotch region 1B side of the abdominal gathers and the skin surface of the wearer, and urine in the lateral direction reaching the front body region 1F side (abdominal side) is likely to pass around to the other lateral direction. For example, in the case where the wearer is a male, when the wearer urinates with the distal end of the male sexual organ facing either the left or right direction, urine tends to pass around the other in the left or right direction, and thus the diaper 1 can suppress leakage of urine.
The linear rubber 4F7 is disposed on the front body region 1F side of the region corresponding to the anus of the wearer (anus corresponding region 30). In other words, the linear rubber 4F7 is disposed on the precursor region 1F side of the groove 14C. With this configuration, the diaper 1 lifts the outer body toward the skin surface side by the contraction force of the linear rubber 4F7, and thereby lifts the portion of the absorber 8 protruding between the grooves 14BL, 14BR toward the skin surface side, but suppresses the lifting of the absorber 8 toward the skin surface side in the area corresponding to the anus (anus corresponding area 30). The diaper 1 can be easily separated from the anus and the skin side of the diaper 1.
In the region corresponding to the anus of the wearer (anus-corresponding region 30), the linear rubber 4F7 and the absorber 8 are non-bonded. This configuration will be described with reference to fig. 5 and 6. As shown in fig. 6, the linear rubber cover piece 13 also extends in the area corresponding to the anus (anus corresponding area 30). Therefore, since the non-skin surface side of the linear rubber cover sheet 13 and the core wrap sheet 7 is non-adhesive, a minute gap is formed between the linear rubber cover sheet 13 and the absorber 8 in the extension region of the linear rubber 4F7 as shown in fig. 5. The linear rubber 4F7 and the linear rubber 4R3 contract, whereby the outer body is pulled, and the gap is widened. Thereby, the diaper 1 more easily forms a space between the absorbent body 8 and the anus of the wearer. In the anus-corresponding region 30, the cover sheet 4 and the inner cover sheet 5 are non-bonded. Thereby, the diaper 1 more easily forms a space between the absorbent body 8 and the anus of the wearer.
In the diaper 1 according to the present embodiment, the linear rubbers 4R3 on the left and right sides extend to the vicinity of the anus corresponding region 30 at a position overlapping the absorbent core 8 c. Thereby, the linear rubbers 4R3 on both sides can pull the absorber 8 in the anus-corresponding region 30 in the left-right direction. The diaper 1 more easily forms a space between the absorbent body 8 and the anus of the wearer.
Even if the absorber 8 is deformed to be convex toward the skin surface side between the grooves 14BL, 14BR on the front side of the groove 14C, the absorber 8 is curved along the curve of the wearer's buttocks by the groove 14C extending in the width direction, so that the absorber 8 can be suppressed from being convex toward the skin surface side in the anus corresponding region 30. The contraction force of the linear rubber 4F7 extending in the longitudinal direction of the diaper 1 also acts on the absorber 8 via the backsheet 6, and the grooves 14BL and 14BR extending in the longitudinal direction can be pulled toward the front side in the longitudinal direction by the contraction force. Since the groove 14C is connected to the front grooves 14BL and 14BR, the grooves 14BL and 14BR are pulled, and the groove 14C is also pulled toward the front side in the longitudinal direction. This makes it possible to prevent the absorber 8 from protruding toward the skin surface side in the anus corresponding region 30 in the diaper 1.
< modification >
In the above-described embodiment, the absorber 8 and the inner cover sheet 5 are non-bonded in the non-bonded region 15 where the linear rubber 4F3 crosses in the width direction, but the absorber 8 and the inner cover sheet 5 may be partially bonded in the non-bonded region 15 shown in fig. 4. In this case, the absorber 8 can be prevented from being displaced from the inner cover sheet 5. The partial bonding portion may be, for example, a widthwise central portion.
< embodiment 2>
Next, a diaper 1 according to embodiment 2 will be described. Fig. 7 is a plan view of the diaper 1 in an unfolded and extended state. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.
In the diaper 1 according to the present embodiment, the linear rubbers 4R3 on the left and right sides do not extend to a position overlapping the absorbent core 8c, but extend to a position overlapping the core wrap sheet 7 of the absorbent body 8. The linear rubber 4R3 can pull the core wrap sheet 7 outward in the width direction, and can also pull the absorbent core 8c outward in the width direction. Even with such a configuration, the diaper 1 is more likely to form a space between the absorber 8 and the anus of the wearer.
< embodiment 3>
Next, a diaper 1 according to embodiment 3 will be described. Fig. 8 is a plan view of the diaper 1 in an unfolded and extended state. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.
Folds 41 extending in the width direction are formed in the front and rear of the anus-corresponding region 30 in the cover sheet 4 and the inner cover sheet 5, which are the outer body of the diaper 1. Folds 41 are formed in front and rear of the anus-corresponding region 30. The folds 41 are formed as valley folds when the diaper 1 is viewed from the skin side. Therefore, the absorbent body 8 and the top sheet 9 on the skin surface side of the outer body are also valley-folded at the fold 41, and the outer body, the absorbent body 8, and the top sheet 9 are formed in a shape recessed toward the non-skin surface side at the fold 41 when viewed from the skin surface side. The folds 41 also function as a support for suppressing shrinkage of the outer body and the absorber 8 on the skin surface side. By providing the fold 41, the diaper 1 can form a space between the wearer and the anus-corresponding region 30, and can suppress the absorbent body 8 from sinking into the cleft of the buttocks. In addition, the diaper 1 can form a space for containing feces by forming a space between the wearer and the anus corresponding region 30. This makes it possible to suppress the deterioration of the wearing sensation of the diaper 1. In addition, the diaper 1 can suppress the exposure of the gluteal cleft of the wearer from the diaper 1 by suppressing the contraction of the outer body and the absorber 8 on the skin surface side thereof by the folds 41.
Further, a crease 41 is formed between the inner ends of the left and right linear rubbers 4R3 in the width direction. Crease 41 may be provided on the extension line of left and right linear rubbers 4R 3. By pulling the crease 41 outward in the width direction by the linear rubber 4R3, the crease 41 expands in the width direction, and the absorber 8 can be separated from the skin of the wearer with the crease 41 as a starting point in the anus-corresponding region 30.
In addition, another crease 42 may be formed between the front and rear creases 41 of the anus-corresponding region 30. The crease 42 is formed in the cover sheet 4 and the inner cover sheet 5 so as to extend in the width direction. The folds 42 are formed as valley folds when the diaper 1 is viewed from the skin side. Therefore, the absorbent body 8 and the top sheet 9 on the skin surface side of the outer body are also valley-folded on the crease 42, and the outer body, the absorbent body 8, and the top sheet 9 are formed in a shape recessed toward the non-skin surface side on the crease 42 when viewed from the skin surface side. Thereby, the diaper 1 can more reliably form a space between the anus corresponding region 30 and the wearer.
Folds 41 and 42 are formed on the extension lines of the inner ends of the left and right linear rubbers 4R3 in the width direction. Folds 41 and 42 are naturally formed by pulling the outer body outward in the width direction by linear rubber 4R 3. The folds 41, 42 may be formed intentionally by bending the outer package.
The non-adhesive region 15 extends toward the front body region 1F and toward the rear body region 1R beyond the portion of the linear rubber 4F3 that extends across the crotch region 1B (hereinafter, this portion may be referred to as a "crossing portion of the linear rubber 4F 3"). The linear rubber 4F3 has a component in the longitudinal direction of the diaper 1 on the outer side in the width direction of the diaper 1 than the absorber 8. Here, the longitudinal component is a component extending and expanding along the longitudinal direction of the diaper 1, and even if the linear rubber 4F3 extends obliquely to the longitudinal direction, the expansion and contraction direction of the linear rubber 4F3 has a longitudinal component.
The non-adhesive region 15 is formed so as to include the front region 1F side of the extension region of the linear rubber 4F3, and has a component that stretches in the longitudinal direction of the diaper 1 on the outer side in the width direction of the cross section of the linear rubber 4F 3. Thus, the outer body (the cover sheet 4 and the inner cover sheet 5) in the non-adhesive region 15 is pulled toward the front body region 1F by the linear rubber 4F 3. The diaper 1 pulls the outer body forward by the linear rubber 4F3, thereby pulling the absorber 8 on the rear side of the non-adhesive region 15 forward, and can incline the rear side in the front-rear direction of the absorber 8 downward (non-skin surface side) in the wearing state. By inclining the absorber 8 downward at the rear side of the longitudinal center portion, the diaper 1 can relatively separate the absorber 8 from the skin of the wearer in the anus corresponding region 30 at the rear side of the center portion. Thereby, the diaper 1 can form a space between the anus corresponding region 30 and the skin of the wearer.
< embodiment 4>
Next, a diaper 1 according to embodiment 4 will be described. Fig. 9 is an example of an exploded perspective view of the diaper according to embodiment 4. The same reference numerals are given to the same components as those of embodiment 1 described above, and the description thereof will be omitted.
The absorber 8 has an absorbent core 8c composed of a plurality of pads and a core wrap sheet 7 wrapping the absorbent core 8c. In the present embodiment, as shown in fig. 9, the absorbent core 8c has an upper absorbent pad 8a and a lower absorbent pad 8b. The upper layer absorbent pad 8a has a substantially hourglass shape with narrowed portions, and the lower layer absorbent pad 8b has a rectangular shape. The width of the lower absorbent pad 8b is substantially the same as the width of the narrowed portion of the upper absorbent pad 8 a. In the present embodiment, the upper absorbent pad 8a is substantially hourglass-shaped with a narrowed central portion. In this way, the absorbent core 8c may be formed by stacking 2 layers of absorbent pads.
In the above-described embodiment, the outer body on the front body region side and the outer body on the rear body region side are integrally formed, but the outer body on the front body region side and the outer body on the rear body region side may be separately provided.
The embodiments and modifications disclosed above can be combined separately.
