Description

Disposable body fluid absorbent clothing

technical field

The present invention relates to disposable body fluid-absorbent clothing, and more particularly to the above-mentioned body fluid-absorbent clothing capable of reducing the wet feeling when worn. the

Background technique

In disposable bodily fluid-absorbent wearing articles for absorbing excreta such as urine, it is well known to reduce the wetness generated when the topsheet contacts the skin by reducing the contact area between the liquid-permeable topsheet and the wearer's skin. feel. For example, in the diaper shown in FIG. 17 of Japanese Patent Application Laid-Open No. 2008-25079 (JP2008-25079A, Patent Document 1), as a liquid-permeable top sheet, a top sheet is used as a liquid-permeable top sheet. A non-woven fabric that is stretched and has a plurality of alternating peaks and valleys in the transverse direction. Once the diaper is worn, the topsheet can contact the skin at the peaks and separate from the skin at the valleys. the

In addition, in the training pants described in Japanese Patent Application Laid-Open No. 5-59601 (JP05-59601A, Patent Document 2), a moisture retention sheet is provided on at least the central region of the surface of the liquid-permeable inner sheet. The moisture retention sheet is partially floated while being partially engaged with the inner panel. In these training pants, the excreted liquid absorbed by the floating part of the wetness retention sheet is hardly absorbed by the core and remains on the floating part. The raised portion makes contact with the skin of the baby wearing the training pants and makes it feel uncomfortable, so that the baby forms a habit of telling others that he wants to urinate. the

The technical problem to be solved by the invention

In the diaper described in Patent Document 1, when a well-known leak-proof bank is formed on both sides of the diaper with a sheet separate from the top sheet, even if the sheet is intended to be joined to the skin-contacting surface of the top sheet, due to skin contact The surfaces are uneven with peaks and valleys, so it is sometimes difficult to join quickly. In addition, when the diaper is worn, the valleys extending vertically on the sides of the waist region wider than the crotch region may cause bodily fluids to flow downward and cause bodily fluids to leak. the

The training pants exemplified in Patent Document 2 are training pants in which the moisture retaining sheet is bonded only to the central region of the surface of the inner sheet, and an example of the joining method of the moisture retaining sheet and the inner sheet is shown, but a part of the moisture retaining sheet is removed from the The inner surface floats up, and excreted fluid remains there. That is, the moisture retention sheet of the training pants has the effect of increasing the moist feeling for the wearer, but does not play the role of reducing the moist feeling. the

The object of the present invention is to provide a disposable body fluid-absorbent wearing article which reduces the moist feeling and has a good effect of preventing leakage of body fluid when worn. the

means of solving technical problems

In order to solve the above-mentioned problems, the object of the present invention is a disposable bodily fluid-absorbent wearing article having a front-rear direction and a transverse direction perpendicular thereto, a crotch region is formed in the front-rear direction, and a front waistline located in front of the crotch region region and a rear waist region located behind the crotch region, at least the crotch region of these regions comprising a liquid-pervious sheet, a liquid-impermeable sheet, and a liquid-absorbent core interposed between these two sheets The liquid-permeable sheet has an opposite surface facing the core material and a non-opposing surface opposite to the opposite surface, and at least a part of the non-opposing surface is formed of a non-woven fabric containing thermoplastic synthetic fibers. Cover with a liquid permeable cover sheet. the

In this wearing article, the characteristics of the present invention are as follows. The non-opposing surface of the liquid-permeable sheet is flat. The cover sheet has a surface facing the skin of the wearer of the wearing article and a back surface facing the non-facing surface of the liquid-permeable sheet, and a plurality of stripes are formed on the surface parallel to each other in the front-rear direction. peaks and troughs alternately appearing in the transverse direction, the back surface is flatly formed, and the back surface is in contact with the non-opposing surface of the liquid-permeable sheet in the transverse direction of the crotch region. A combined central region and side regions on each outer side on either side of the central region, in which the back surface is non-joined with the non-opposite surface. The side region includes at least one valley portion and at least one peak portion located outside the valley portion in the lateral direction, and is separable from the non-opposing surface in the thickness direction of the liquid-permeable sheet. the

In one embodiment of the present invention, in the nonwoven fabric, the density at the center portion in the transverse direction on the valley portion is lower than the density at the center portion in the transverse direction on the peak portion. the

In another embodiment of the present invention, at the center of the front-to-back direction of the crotch region, the covering sheet extends to both lateral edges of the core material. The lateral dimension of the side regions is in the range of 10 to 50 mm. the

In another embodiment of the present invention, in the center of the crotch region in the front-rear direction, the side regions of the covering sheet are located inside the lateral side edges of the core material. the

In another embodiment of the present invention, the two sides of the transverse direction on the crotch region are formed to be elastically stretchable in the front-rear direction, stretchable in contraction, and elastically compatible with the wearer's legs. For the leak-proof bank in contact, both ends of the leak-proof bank in the front-rear direction are joined to both end parts in the front-back direction of the side region on the cover sheet. the

In another embodiment of the present invention, said central region of said cover sheet is hydrophilic and said side regions are hydrophobic. the

Invention effect

In the disposable body fluid-absorbent wearing article of the present invention, since the liquid-permeable cover sheet has peaks and valleys that are parallel to each other and extend in the front-back direction on the surface in contact with the skin, compared with a cover sheet with a flat surface, The small contact area with the skin can reduce the wet feeling caused by the cover sheet wetted by body fluids in contact with the skin. In addition, the back of the cover sheet of the present invention is flat, and the back of the central region is bonded to the flat non-opposite surface of the liquid-permeable sheet, so bodily fluids can move from the peaks and valleys of the cover sheet to the liquid-permeable sheet, and then Further, it quickly moves to the core material to form a wearing article that absorbs body fluids quickly and has a high effect of preventing leakage of body fluids. Moreover, since the side area of the cover sheet can be separated from the non-opposite surface of the liquid-permeable sheet below it, the body fluid can be prevented from flowing back from the core material to the skin in this side area, reducing the wetting of the skin by the backflow of body fluid. In the form in which the side region extends to the side edge of the core material and in the form located inside the side edge of the core material, it is easy to form a leak-proof bank even if the covering sheet is present. the

Detailed ways

Hereinafter, the disposable body fluid-absorbent wearing article according to the present invention will be specifically described by taking a disposable diaper as an example. the

FIG. 1 is a partially cutaway plan view of a disposable diaper 1 . The diaper 1 has a liquid-permeable topsheet 2, a liquid-impermeable backsheet 3, and a bodily fluid-absorbent core material 4 between these two sheets 2, 3. A part of the topsheet 2 is formed by a hot melt adhesive 43. The installed liquid-permeable cover sheet 5 is covered. The top sheet 2 and the back sheet 3 are bonded via a hot-melt adhesive (not shown) at the overlapping portion extending from the periphery of the core material 4 . In addition, the diaper 1 has a front-back direction A, a width direction B, and a thickness direction C (refer to FIG. 2 ) that are perpendicular to each other. Rear waist region 8 behind the crotch region 6 . Both side edges 11 of the crotch region 6 are convexly curved inwardly in the transverse direction B, and between the top sheet 2 and the bottom sheet 3 on the both side edges 11, the leg circumference elastic members 12 extend in an elongated state. At least one of the two sheets 2 and 3 is bonded via a hot-melt adhesive (not shown). Fastening belts 14 for connecting the front and rear waist regions 7 and 8 are attached to both side edges 13 of the rear waist region 8 . Between the top sheet 2 and the bottom sheet 3 of the end edge portions 17, 18 of the front and rear waist regions 7, 8, the waist elastic members 7a, 8a extend in the transverse direction B in an elongated state, and are connected through a hot-melt adhesive (not shown). Bonded to at least one of the two sheets 2,3. The cover sheet 5 is attached to the top sheet 2 symmetrically with respect to the center line P-P in the front-back direction bisecting the width of the diaper 1, and extends between the edge portions 17 and 18. the

Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1 , and line II-II coincides with a transverse centerline Q-Q that bisects the dimension in the front-back direction A of the diaper 1 . In FIG. 2, the top sheet 2 has the non-opposite surface 2a of the opposing surface 2b which opposes the core material 4, and the opposite surface, and the non-opposed surface 2a forms a flat surface. The core material 4 is formed by wrapping an aggregate of pulverized pulp and liquid-absorbent materials 21 such as superabsorbent polymer particles with a liquid-permeable sheet 22 such as tissue paper. The cover sheet 5 has a surface 31 in contact with the skin (not shown) of the diaper wearer in the thickness direction C and a back surface 32 opposite to the non-opposing face 2a of the top sheet 2, and has a central region 41 and both side regions in the width direction B. 42. The surface 31 has peaks 34 that are convex toward the skin and extend in the front-back direction A, and valleys 36 that are concave and extend in the front-back direction A, and these peaks 34 and valleys 36 are formed alternately in the transverse direction B. Multiple (refer to Figures 3 and 4). In the back side 32, the back side 32 of the central region 44 is bonded with the non-opposite surface 2a of the top sheet 2 by the hot-melt adhesive 43, and the back side 32 of each side region 42 is in a non-joint state with the non-opposite surface 2a, and can be connected with the non-opposite side. Face 2a is separated. The hot-melt adhesive 43 is intermittently applied to the cover sheet 5 and the top sheet 2 so as not to substantially interfere with the liquid permeability of the cover sheet 5 and the top sheet 2 . In the illustrated example, the both side regions 42 are located inside the side edges 4 a of the core material 4 . the

Figs. 3 and 4 are an example of movement of the top sheet 2 and the cover sheet 5 when the diaper 1 is worn, and are the same diagrams as Fig. 2 . In Fig. 3, once the diaper 1 is subjected to, for example, body pressure so that the side edges 11 of the crotch region 6 are bent downward in the thickness direction C together with the core material 4, the top sheet 2 which is substantially horizontal in Fig. 2 is also similarly bending. However, the side region 42 of the cover sheet 5 may be separated from the non-opposing surface 2a in a horizontal state or a nearly horizontal state. In addition, as shown in FIG. 4 , when a lateral force F is applied to the side region 42 , the side region 42 can be deformed in a curled or bent manner to be separated from the non-opposing surface 2 a. In order to easily maintain such a horizontal state or perform curling, the side region 42 includes at least one peak portion 34 and one valley portion 36 . The peak portion 34 is a highly rigid portion in the side region 42 and functions to keep the side region 42 in a horizontal state. The valley portion 36 is a portion with low rigidity in the side region 42, so that the side region 42 is easily curled or bent in the lateral direction B. In the crotch region 6 of the diaper 1, as shown in Figures 3 and 4, the side region 42 separated from the non-facing surface 2a is located closer to the skin than the non-facing surface 2a, which can prevent the non-facing surface 2a in a wet state from contacting the skin. touch. the

5 and 6 are partial perspective views of the sheet 51 used as the cover sheet 5 and views showing part of the end face of the sheet 51 . The sheet 51 is composed of hydrophilic fibers (not shown) composed of semi-synthetic fibers such as thermoplastic synthetic fibers 52, 40-0% by weight of 60-100% by weight of thermoplastic synthetic fibers or rayon fibers (not shown), and the weight per unit area is 20-100%. 100 g/m ² of nonwoven fabric is formed, and in the illustrated example, a nonwoven fabric of 100% by weight of thermoplastic synthetic fibers 52 is used. In addition, the sheet 51 has a first direction L that coincides with the front-back direction A of the diaper 1 , a second direction M that coincides with the lateral direction B, and a third direction N that coincides with the thickness direction C when the sheet is used. The upper surface 51a of the sheet 51 is a part that becomes the surface 31 of the cover sheet 5, and the lower surface 51b is a part that becomes the back surface 32 of the cover sheet 5. The peaks 34 and valleys 36 in FIG. 2 are formed on the upper surface 51a, and the lower surface 51b is formed flat. . The heights of the plurality of peaks 34 are substantially the same, and the sheet 51 has a thickness j at the top of the peaks 34 . The plurality of valleys 36 have substantially the same depth from the top of the peaks 34 , and the sheet 51 has a thickness k at the bottom of the valleys 36 . On the sheet 51, preferably, the thickness k is not more than 1/3 of the thickness j, the thickness j is in the range of 1.5-5 mm, and 2 to 5 peaks 34 are formed relative to the length 10 mm of the sheet 51 in the second direction M. The sheet 51 includes a portion 41a serving as the central region 41 and portions 42a serving as the side regions 42 in FIG. 2 . In order to improve the liquid permeability of the sheet 51, the thermoplastic synthetic fibers 52 of at least a portion 41a of the portion 41a and the portion 42a are subjected to a hydrophilic treatment. On the part 42a in the sheet 51, although it is possible to make the thermoplastic synthetic fiber 52 undergo hydrophilic treatment, when the part 42a is used as the side region 42, in order to prevent it from being easily wetted by body fluids, the thermoplastic synthetic fiber 52 is preferably not treated with hydrophilic treatment. Water treatment is used as a hydrophobic fiber or after water repellent treatment.

In addition, in order to make the sheet 51 easily deformable as shown in FIG. The value of the thickness k of the valley portion 36 is smaller than the value of the thickness j on the peak portion 34 . The sheet 51 in the illustrated example is made such that the density of the valleys 36 is lower than that of the peaks 34, so that, in the second direction M, portions of low density and portions of high density alternate. On the sheet 51, the density of the peaks 34 and the density of the valleys 36 are compared as follows. That is, place the sheet 51 of FIG. 4 on a horizontal plane, take an enlarged picture of the cross-section, obtain the vertical line R ₁ passing through the top of the thickness j at the peak 34 from the picture, and measure the thermoplastic composition crossing the vertical line R ₁ . The number Q ₁ of fibers 52 . Then, a perpendicular line R ₂ passing through the bottom of the thickness k at the valley portion 36 is obtained, and the number Q ₂ of thermoplastic synthetic fibers 52 crossing the perpendicular line R ₂ is measured. Thereafter, the ratio (Q ₁ /j) of the number Q ₁ to the thickness j is obtained as the density of the peaks 34 , and the ratio (Q ₂ /k) of the number Q ₂ to the thickness k is obtained as the density of the valleys 36 .

When wearing the diaper 1 of Fig. 1 formed in this way, the peak portion 34 in the cover sheet 5 is in contact with the skin, and the valley portion 36 is separated from the skin, so compared with the situation where the top sheet 2 directly contacts the skin, the contact area with the skin can reduce the wet feeling produced when the diaper 1 is in a wet state. In addition, if the cover sheet 5 of the illustrated example extends from the edge portion 17 of the front waist region 7 to the edge portion 18 of the rear waist region 8, the gap formed between the peak portion 36 and the skin becomes a ventilation channel, and the diaper 1 Since the front and rear are open to the atmosphere, the internal and external air permeability of the diaper 1 becomes favorable. In addition, the present invention may be implemented in such a manner that the covering sheet 5 does not reach one or both of the edge portions 17 and 18 . Bodily fluid excreted toward the cover sheet 5 is absorbed by the core material 4 through the top sheet 2 from the central region 41 in the cover sheet 5 . A part of bodily fluid may spread in the lateral direction B on the cover sheet 5 or in the lateral direction B on the top sheet 2 . But, on the cover sheet 5 that the density on the peak portion 34 of the cover sheet 5 is higher than the density on the valley portion 36, the valley portion 36 can suppress the body fluid on the cover sheet 5 from spreading to the lateral direction B, and prevent the body fluid in the crotch region 6 from spreading. Bodily fluids on both side edges 11 soil the skin. And, during wearing diaper 1, once body pressure is applied on the core material 4, the bodily fluid that has been absorbed by core material 4 may flow backwards from core material 4 toward cover sheet 5 and wet skin, but the both sides area of cover sheet 5 42 is not joined with the top sheet 2, but tends to be separated from the top sheet 2 as shown in Figures 3 and 4, therefore, the bodily fluids that flow back from the core material 4 to the top sheet 2 are relatively easy to cover in the central region 41. The sheet 5 moves, but it is also difficult to move towards the cover sheet 5 in the side regions 42 . Therefore, the both side regions 42 are less likely to become wet due to the bodily fluid flowing back, and the skin on the both side regions 42 is not wetted. Especially in the side regions 42, when the thermoplastic synthetic fibers 52 are in a hydrophobic or water-repellent state, the side regions 42 will not become wet with bodily fluids, and the effect of not wetting the skin is further enhanced. In addition, the side regions 42 are soft parts that can cover the hot-melt adhesive 43 that joins the cover sheet 5 and the top sheet 2, preventing the adhesive 43 from contacting the skin during wearing the diaper 1 and causing irritation. In addition, since the cover sheet 5 of the illustrated example extends in the front-rear direction A inside the both side edges 11 of the crotch region 6, even when the diaper 1 is worn, bodily fluids flow along the valleys 36, and the bodily fluids are hardly Flow towards the outside of the diaper 1 . the

An example of the manufacturing method of the sheet|seat 51 used as the cover sheet 5 of the diaper 1 is shown below. First, while moving a web (カードウウエブ) of the same thickness formed of thermoplastic synthetic fibers 52 in the machine direction, heat is sprayed onto one side of the web from a plurality of nozzles arranged at a desired pitch in a direction intersecting the machine direction. Air or columnar water flow. The web is placed on an air permeable or water permeable conveyor belt with which it moves in the machine direction. The pitch of the nozzles is made to match the pitch of the valleys 36 on the sheet 51 in advance. On this web, the thermoplastic synthetic fibers 52 move in the intersecting direction directly under the nozzles, thereby forming low-density valleys 36 and forming high-density peaks 34 between adjacent nozzles. As the thermoplastic synthetic fiber 52, fibers such as polyethylene, nylon, or polyester, or composite fibers of polyethylene, nylon, or polyester, or the like are used. As the top sheet 2 of the diaper 1, a nonwoven fabric made of thermoplastic synthetic fibers, an apertured plastic film, or the like can be used. As the backsheet 3, a plastic film or a laminated sheet of a plastic film and a nonwoven fabric or the like can be used. As the core material 4, liquid-absorbing materials such as pulverized pulp and superabsorbent polymer particles may be used alone or in combination. The liquid-absorbent material is preferably covered with a liquid-permeable and spreadable sheet such as tissue paper. the

FIG. 7 shows an example of an embodiment, and is the same diagram as FIG. 2 . In the diaper 1 of FIG. 7, the side area|region 42 of the cover sheet 5 spreads in the horizontal direction B so that it may reach the side edge 4a of the core material 4, or may exceed the side edge 4a. Such a diaper 1 has the following effects in addition to the same effects as those of the diaper 1 of FIG. 2 . That is, even if the body fluid absorbed by the core material 4 flows back to the top sheet 2, or the body fluid excreted in the central region 41 of the cover sheet 5 diffuses to the lateral edge 4a of the core material 4 after being absorbed by the top sheet 2 or the core material 4 Since the side edge 4a is covered by the side region 42 of the cover sheet 5, the body fluid contained in the side edge 4a and its vicinity will not wet the skin. Although the side regions 42 acting in this way also depend on the size of the diaper 1, they preferably have a size of 10 to 50 mm on the transverse center line Q-Q. the

8 and 9 show an example of an embodiment of the present invention, are the same views as FIG. 1 , and are cross-sectional views showing line IX-IX in FIG. 8 . On the diaper 1 of Fig. 8, leak-proof banks 80 are formed on both side edges 11 of the crotch region 6. The leak-proof bank 80 is formed by a sheet of plastic film or non-woven fabric or the like which is practically liquid-impermeable, and the outer edge portion 82, the front end portion 83 and the rear end portion 84 are relative to the top sheet overlapping with them by the hot-melt adhesive 85. 2 or the cover sheet 5 is joined. An elastic member 86 extending in the front-rear direction A in an extended state is attached to the inner edge portion 81 of the leak-proof bank 80 so as to be expandable and contractable. On the leakproof bank 80, the fact that the sheet is substantially liquid-tight means that the sheet has the minimum liquid-tightness or better liquid-tightness necessary to be the leakproof bank 80. the

Though such leak-proof dike 80 is the state that falls on the cover sheet 5 in Fig. 8,9, if put on diaper 1 and bend in front-rear direction A, then elastic member 86 shrinks, as indicated by the imaginary line in Fig. 9 As shown, the inner edge portion 81 stands up from the cover sheet 5 toward the wearer's skin (not shown), which can prevent bodily fluids from flowing in the lateral direction B and prevent side leakage of bodily fluids in the crotch region 6 . In addition, the side region 42 on the cover sheet 5 is positioned at the lower side with respect to the inner edge portion 81 of the leak-proof bank 80 in the fallen state, and may also be on the lower side with the top sheet with respect to the inner edge portion 81 in the erect state. 2 act separately (cf. Fig. 9). Therefore, the inner edge portion 81 of the leakage preventive bank 80 can stand upright without interfering with the side region 42 of the cover sheet 5 . This covering sheet 5 not only has the dimension of the lateral direction B smaller than the dimension of the lateral direction B of the top sheet 2, but also is smaller than the dimension between the outer edge portions 82 of a pair of leak-proof banks 80, so the sheet forming the leak-proof banks 80 is installed on the diaper. 1, the cover sheet 5 will not get in the way. In addition, in this diaper 1, in the vicinity of the front and rear ends 83, 84 of the leak-proof bank 80, the inner edge 81 and the front and rear ends on the side region 42 of the covering sheet 5 overlapping therewith can be joined by a hot-melt adhesive 87. Sections 45, 46. The leakage preventive bank 80 in this state functions to separate at least a part of the side region 42 of the covering sheet 5 from the top sheet 2 when the inner edge portion 81 stands up. the

The diaper 1 illustrated above is an open type diaper, but the present invention can also be implemented as a pants type diaper. In addition, the present invention described by taking the diaper 1 as an example can also be implemented in disposable bodily fluid absorbent articles such as sanitary napkins. the
