Description

The present invention is related to waste absorption sheet for excrement absorption of the pet. More particularly, walls etc. excrement bounced excrement absorption pets capable of preventing walls soiling, about the excretions absorbed sheet.

  Pet excrement absorption sheets are used to treat excrement of pets such as dogs and cats kept in the home. This pet excrement absorption sheet is composed of a liquid-permeable top sheet such as a nonwoven fabric, a liquid-impervious back sheet such as a resin film, and an absorbent core interposed between the top sheet and the back sheet. Yes.

  The absorbent core is, for example, one having a superabsorbent resin layer provided on the surface of the pulp layer, or one composed of a pulverized pulp layer and a superabsorbent resin dispersed in the pulp layer, or Only the superabsorbent resin layer is formed by being covered with absorbent paper such as tissue paper. This type of excreta absorbing sheet is used by being disposed at a corner of a room or bathroom, that is, near a wall, mainly for the purpose of absorbing moisture such as urine.

However, depending on the position of the pet's urination, the urine may splash out of the excrement absorbing sheet. Especially, dogs and others are instinctively urinating sideways by raising their hind legs. There is a problem that the surrounding walls get dirty due to many splashes. In order to solve such a problem, Patent Document 1 below discloses a urine mat for a dog that can be bent and installed continuously from a floor to a wall.
No. 3-6205

  However, the urine mat for slaughter dogs is also provided with an absorber in the portion installed on the wall. Therefore, the mat is relatively large and not only high in cost, but also bulky and inconvenient to carry and store. In addition, since the part installed on the wall has an absorber, it is relatively heavy, it is difficult to keep it on the wall continuously, and the part installed on the wall tends to slip down to the floor surface There is. To prevent this, the adhesive can be strengthened. However, if the adhesive strength is increased, the adhesive remains on the wall when the mat is peeled off.

The present invention is made to solve the conventional problems described above, subjecting the excrement absorption sheet for splashing installation portion and the wall surface as it can prevent contamination of the walls due to the difficult slipping pet excrement Hisage It is aimed.

Excrement-absorbing sheet of the present invention includes a liquid permeable topsheet, a liquid-impervious backsheet, absorbent mat square with an absorbent core disposed between the topsheet and the backsheet, and the and a flap backsheet is formed by extending from at least one side of said absorbent mat, extending length from the absorbent mat of the flap, the extending direction parallel to the absorption mat side of the flap More than 0.3 times the length , the liquid receiving side is embossed at least in the area where the flap is formed on the back sheet, and the flap is hooked on the wall surface in a state of being bent at a substantially right angle from the absorbent mat. An adhesive tape is provided for use in absorbing pet excreta. This extension length is preferably 0.5 times or more.
Further, the excreta absorbent sheet of the present invention is a rectangular absorbent mat having a liquid-permeable surface sheet, a liquid-impermeable back sheet, and an absorbent core interposed between the surface sheet and the back sheet, And the back sheet has a flap formed extending from at least one side of the absorbent mat, and the extension length of the flap from the absorbent mat is the side of the absorbent mat parallel to the extending direction of the flap. The liquid receiving side is water-repellent at least in the region where the flap is formed on the back sheet, and the flap is folded on the wall surface in a state of being bent at a substantially right angle from the absorbent mat. An adhesive tape for hooking is provided and used for absorbing excrement of pets.
Furthermore, the excreta absorbing sheet of the present invention includes a liquid-permeable top sheet formed of a nonwoven fabric, a liquid-impervious back sheet, and an absorbent core interposed between the top sheet and the back sheet. A rectangular absorbent mat, and a flap formed by extending the top sheet and the back sheet from at least one side of the absorbent mat, and the extension length of the flap from the absorbent mat is the extension direction of the flap The length of the side of the absorbent mat parallel to the surface is 0.3 times or more, and the flap is provided with an adhesive tape for hanging on the wall surface in a state of being bent at a substantially right angle from the absorbent mat. It is used for the excretion absorption.

The preferred properly the extended length is more than 2 times the edge. The extension length is a value measured from the side (terminal portion) of the absorbent core located closest to one side of the absorbent mat.

The pet excrement absorbing sheet of the present invention is used by installing the absorption mat on a floor or a pet toilet, and hanging the flap on a wall surface such as a wall of a house or an inner wall of a pet toilet with an adhesive tape . . Since this flap is formed from a back sheet or a back sheet and a top sheet and does not have an absorbent core inside, it can be obtained at a lower cost than the conventional one. Moreover, since the flap is very light, even if the adhesive force of the adhesive for holding it on the wall is not so strong, the flap does not slide off the wall surface.

Moreover, when the surface sheet is overlaid on the surface that receives the liquid of the flap, it is possible to prevent the liquid applied to the flap from widely scattering to other areas.

Since the flap of the excreta absorbing sheet of the present invention is formed from the back sheet or the back sheet and the top sheet, it can be obtained at a lower cost than the conventional one. Further, since the flap is very light, the adhesive for holding it on the wall does not have to have a very strong adhesive force.

Hereinafter, the excreta absorbing sheet of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the excreta absorbing sheet of the present invention as seen from the liquid receiving side. 2 is a sectional view taken along line II-II in FIG. FIG. 3 is a cross-sectional view of the second embodiment of the excreta absorbing sheet. FIG. 4 is a perspective view illustrating a use state when the excreta absorbing sheet shown in FIGS. 1 to 3 is used for pets. 5 is a perspective view showing an example of a method for producing the excreta absorbing sheet shown in FIGS. 1 and 2, FIG. 6 is a perspective view showing an example of a method for producing the excreta absorbing sheet shown in FIG. 3, and FIG. FIG. 8 is a cross-sectional view showing a reference example of each excreta absorbing sheet. In addition, in FIG.2, FIG.3, FIG.7, FIG. 8, the thickness of the excretion absorption sheet is drawn a little exaggerated.

Pet excrement-absorbing sheet 1 of the present invention, as shown in FIGS. 1 and 2, a rectangular absorbent core 4 of a backsheet 3 rectangular liquid-impermeable, the surface of the liquid-pervious rectangular sheet 2 It is sandwiched between. And the surface sheet 2 and the back surface sheet 3 are joined by the hot-melt-type adhesive etc. in the part which the absorption core 4 does not exist, ie, the outer peripheral area | region of the absorption core 4. FIG. Alternatively, the top sheet 2 and the back sheet 3 may be heat-sealed to each other in the peripheral region. The topsheet 2 is, for example, a 45 cm × 32 cm rectangle, and the absorbent core is slightly smaller than that. In addition, the magnitude | size of the absorption core 4 and the surface sheet 2 can be suitably changed according to the physique of the target pet. For example, a rectangle of about 90 × 120 cm may be used.

  As shown in FIG. 2, the back sheet 3 is larger than the absorbent core 4 and the top sheet 2 and extends in the X direction on the long sides of the absorbent core 4 and the top sheet 2 to form a liquid-impermeable flap 10. is doing. That is, on one side of the rectangular absorbent mat 1a formed by the top sheet 2, the back sheet 3 and the absorbent core 4, only the back sheet 3 extends to form the flap 10, and the entire rectangular excrement is absorbed. Sheet 1 is formed. In addition, the shape and size of the excretion absorbing sheet 1 are adjusted as appropriate, and may be square as a whole. And the adhesive tapes 11 and 11 are provided in the edge part (edge part 3b of the back surface sheet 3) of the flap 10 as a peeling adhesive means.

  In using the excreta absorbing sheet 1, as shown in FIG. 4, the absorbent mat 1 a is installed on the floor 15, the flap 10 is raised vertically to the floor 15, and the adhesive tape 11 is used. Hang on wall 16 or the like. When used in the state shown in FIG. 4, for example, even if a male dog raises his hind legs and urinates and urine scatters to the wall side, the wall is not soiled due to the presence of the impermeable flap 10. In order to effectively prevent scattering of urine on the wall, the extension length of the portion of the flap 10 that extends laterally from the end portion 2b of the topsheet 2 (the extension of the backsheet 3 in the X direction). The protruding length 10p is preferably 0.3 times or more and 2.0 times or less of the short side length (length in the X direction) 4p of the absorbent core 4. The extension length 10p is more preferably 0.5 times or more the short side length 4p of the absorbent core 4.

  The liquid-permeable surface sheet 2 is a point bond nonwoven fabric, for example. The point bond nonwoven fabric is formed of hydrophilic fibers or hydrophobic fibers subjected to hydrophilic treatment, and the fibers are, for example, synthetic fibers such as polyethylene fibers, polypropylene fibers, or composite fibers thereof. The point bond nonwoven fabric may contain water-absorbing fibers such as rayon fibers. However, the liquid-permeable nonwoven fabric formed with the hydrophobic fiber and the nonwoven fabric provided with many opening parts may be sufficient.

  The liquid-impermeable back sheet 3 is a polyolefin-based polyethylene (PE) film or a vinyl sheet. Or the nonwoven fabric may be laminated | stacked on the back surface of the film. Further, on the liquid receiving side of the back sheet 3, it is preferable that at least a region where the flap 10 is formed is subjected to a surface treatment. By applying the surface treatment, the urine hitting the wall does not splash and pollute other places. As the surface treatment, the surface is subjected to a corona discharge treatment or a surfactant coating. Alternatively, the effect of preventing urine scattering can also be expected by making the film constituting the back sheet 3 uneven by embossing or the like.

  However, the surface of the back sheet 3 where the flap 10 is formed may be coated with fluorine or silicon on the surface to improve water repellency. For example, when the excreta absorbing sheet 1 is installed as shown in FIG. 4, the urine splashed to the flap 10 flows down on the flap 10 and moves to the absorbent mat 1a side, and the absorbent core 4 of the absorbent mat 1a. It may be absorbed in. In this case, a region near the absorbent core 4 in the flap 10 may have high water repellency, and a region far from the absorbent core 4 may have a high scattering prevention effect.

  In addition, a liquid-impermeable back sheet 3 formed of a nonwoven fabric or paper and coated with fluorine or silicon on the surface to improve water repellency and waterproofness can be used.

  In the absorbent core 4, the superabsorbent resin 5 dispersed in the pulp layer 6 is wrapped in absorbent paper such as tissue. The absorbent core may be one in which a superabsorbent resin is provided on both the surface and the bottom of the pulp layer. Examples of the superabsorbent resin 5 include polyacrylic acid-based, polyvinyl alcohol-based, maleic anhydride and other addition polymers, polyether-based, polymers represented by condensation systems, starch-based, cellulose-based other polysaccharides, collagen, and the like. The granular body which consists of proteins, such as these, can be used. Examples of the superabsorbent resin are a sodium polyacrylate crosslinking compound, a sodium polyacrylate starch copolymer, and a polyacrylonitrile cellulose copolymer. Among these, sodium polyacrylate or a crosslinking compound of polyacrylic acid is preferable because it is inexpensive. In addition, the superabsorbent core 4 is not provided with a superabsorbent resin, and may be formed only of pulp.

  When the absorbent core 4 is covered with a tissue, it can be easily handled in the manufacturing stage. Moreover, it can suppress that the comparatively hard superabsorbent resin damages the back surface sheet 3 by presence of a tissue. The tissue immediately below the top sheet 2 of the pet excreta absorbing sheet 1 is preferably colored in blue or the like so as to give a clean feeling.

  For example, as shown in FIG. 2, the adhesive tape 11 is provided on the liquid receiving side and is folded in three into a Z shape so that it does not get in the way when stored. In use, the adhesive tape 11 extends in the X direction as shown in FIGS. The layer is exposed and hung on the wall. Alternatively, it may be folded in half in a V shape, stretched during use and peeled off the release paper to expose the adhesive layer and be hooked on the wall. In addition, the adhesive tape may be a double-sided tape, and may be provided on the back side of the back sheet 3 (opposite the liquid receiving side). In addition to the adhesive tape, any means can be used as long as it can be hooked on the wall. For example, a hook or a hook-and-loop fastener may be used to hook the wall. In addition, a loop or hook provided on the excrement absorbing sheet may be hooked on a protrusion provided on the wall surface in advance.

Next, a second embodiment shown in FIG. 3 will be described. In the excreta absorbing sheet 1 shown in FIG. 3, the top sheet 2 and the back sheet 3 have substantially the same area, and the end 2 b of the top sheet 2 extends to the same position as the end 3 b of the back sheet 3. The flap 10 is formed by a stack of the top sheet 2 and the back sheet 3. In this case, since the nonwoven fabric of the top sheet 2 covers the liquid receiving side of the flap 10, a small amount of urine is held by the top sheet 2 and further less splashed to other places. In this case, as the extension length of the flap 10, the length from the end portion (4b shown in FIG. 1) of the absorbent core 4 to the end portion 3b of the back sheet 3 is the short side length (X (Length in the direction) is preferably 0.3 times or more of 4p, more preferably 0.5 to 2.0 times.

  FIG. 5 shows an example of a method for producing the excreta absorbing sheet 1 having the structure shown in FIGS. 1 and 2. In this manufacturing method, the back sheet 3 is folded in two so that the portion that will become the flap 10 mainly overlaps the back side, and the back sheet 3 is folded in two so that the folding line 3A is along the MD direction. Sent. Absorbing cores 4 are placed at regular intervals on the front side of the folded back sheet 3. Then, the top sheet 2 is supplied in the MD direction, the absorbent core 4 is sandwiched between the back sheet 3 and the top sheet 2 that are folded in two, and the back sheet 3 and the top sheet 2 at the outer peripheral edge of the absorbent core 4 Are bonded with a hot melt adhesive. And each excretion absorption sheet 1 is completed by cut | disconnecting with the cutting line CL.

  The completed excreta absorbing sheet 1 is packed in a folded state such as a two-fold or a four-fold with the back sheet 3 folded in two. At the time of use, the portion where the absorption core 4 is sandwiched becomes the absorption mat 1a, and the flap 10 is formed by developing the folded back sheet 3.

  In the manufacturing method shown in FIG. 5, since the back sheet 3 is fed in a folded state, the feed width on the manufacturing apparatus may be based on the width dimension W of the back sheet 3 folded in half. Therefore, the width of the production line can be shortened, and the enlargement of production equipment can be avoided.

  FIG. 6 shows an example of a method for producing the excreta absorbing sheet 1 shown in FIG. In this manufacturing method, the back sheet 3 is fed in the MD direction, and the absorbent core 4 is placed on the back sheet 3 at an interval. Then, the top sheet 2 is fed in the MD direction from above, and the absorbent core 4 is sandwiched between the back sheet 2 and the top sheet 3. Then, at least in the peripheral region outside the absorbent core 4, the back sheet 3 and the top sheet 2 are bonded with a hot-melt adhesive or the like.

  The laminated body formed as described above is sent in the MD direction and cut along the cutting line CL to complete each excrement absorbing sheet 1. Here, by adjusting the feeding speed of the laminate in the MD direction and the cutting timing with the cutter, in the laminated body after cutting, the absorbent core 4 is in the MD direction with respect to the back sheet 3 and the top sheet 2. It will be sandwiched between the offset positions. In the excreted absorbent sheet 1 that has been cut, the region where the absorbent core 4 is sandwiched becomes the absorbent mat 1a, and the portion where the back sheet 3 and the top sheet 2 continuous with each other is the flap 10.

  Also in the manufacturing method shown in FIG. 6, the width dimension on the manufacturing apparatus may be based on the width dimension W of the back sheet 3 and the top sheet 2, and it is not necessary to increase the width dimension of the manufacturing apparatus. Further, the length of the flap 10 can be easily set by adjusting the feeding speed of the laminated body, the mounting speed of the absorbent core 4 and the cutting timing with the cutter.

FIG. 7 shows a reference example of the excreta absorbing sheet 1. In the case shown in FIG. 7, the width dimension of the back sheet 3 and the top sheet 2 is both substantially W, and the absorbent core 4 is sandwiched between the back sheet 3 and the top sheet 2, and the outer peripheral edge of the absorbent core 4. The back sheet 3 and the top sheet 2 are bonded in the region.

  And the edge part 9a of the liquid-impermeable sheet 9 is joined on the edge part 2b of the surface sheet 2, and the said liquid-impermeable sheet 9 is manufactured in the state piled up on the absorption mat 1a. When using the excreta absorbing sheet, the flap 10 can be formed by spreading the liquid-impermeable sheet 9 laterally. This flap 10 is hooked on the wall surface 16 as shown in FIG.

8, FIG. 9 and FIG. 10 are partially enlarged cross-sectional views of the peripheral region showing a reference example of the excreta absorbing sheet shown in FIG. In FIG. 8, the liquid-impermeable sheet 9 is surface-bonded to the back sheet 3 with a hot-melt adhesive or the like in the outer peripheral region of the absorbent core 4. In addition, the liquid-impermeable sheet 9 and the back sheet 3 may be bonded on all the surfaces in contact with each other, but are applied in a continuous line or a spiral shape of one or a plurality of adhesives. It may be joined by an adhesive. At this time, the top sheet 2 is sandwiched between the liquid-impervious sheet 9 and the back sheet 3, but the end 2 b of the top sheet 2 has the end 9 a of the liquid-impervious sheet 9 in the X direction and It does not extend to the same position as the end 3 b of the back sheet 3. That is, the liquid-permeable surface sheet 2 does not appear at the end of the excreta absorbing sheet on the side where the flap 10 is provided.

  In this case, even if urine moves along the liquid-permeable surface sheet 2 and moves to the end portion of the excreta absorbing sheet, the urine can move only to the end portion 2b of the surface sheet 2, and further to the end portion side. The movement is blocked by the liquid-impervious sheet 9 and the back sheet 3 joined by the adhesive 20. Therefore, urine does not leak or ooze out from the end of the excreta absorbing sheet from the end of the excreta absorbing sheet.

  In FIG. 9, the end 3 b of the back sheet 3 is extended longer in the X direction (in the direction away from the absorbent core 4) than the end 2 b of the top sheet 2 and the end 9 a of the liquid-impermeable sheet 9. The end 3b is wound up in the Z direction. Thereafter, the end 3 b of the back sheet 3 is surface-bonded to the surface of the end 9 a of the liquid-impermeable sheet 9 with the adhesive 20. In this case, as in the example of FIG. 8, even if urine travels through the liquid-permeable top sheet 2, the urine may be blocked by the liquid-impervious back sheet 3 and leak out of the excreta absorbing sheet. Absent.

  In FIG. 10, instead of extending the back sheet 3 as shown in FIG. 9, the liquid-impervious sheet 9 forming a flap is extended in the X direction, and the extended end 9 a is used as the end of the back sheet 3. Surface bonding is performed by an adhesive 20 on the back side of 3b. Even in this case, urine that has flowed to the end portion through the top sheet 2 is blocked by the liquid-impermeable sheet 9 and does not leak outside the excreta absorbing sheet.

11, 12 and 13 are shown to cross-sectional view of the reference example of each excrement-absorbing sheet.

  The excrement absorbing sheet 30 shown in FIG. 11 is obtained by deforming the excrement absorbing sheet 1 shown in FIG. In the excrement absorbing sheet 30, the flap 10 extending on one side of the absorbent mat 1a is folded with the surface sheet 2 sandwiched between the edges of the absorbent mat 1a, and the absorbent core 4 of the absorbent mat 1a is folded at the joint 10s. It is joined to the surface 1s of the covering surface sheet 2. In this joining part 10s, the said surface sheet 2 and the flap 10 are joined by the hot-melt-type adhesive agent or heat welding continuously in the paper surface orthogonal | vertical direction (Y direction) of FIG. At this time, the distance 25 from the joint 10s to the end 24 of the absorbent mat 1a is about 10 to 50 mm, and the distance 26 from the joint 10s to the end 4b of the absorbent core 4 is about 5 to 45 mm. It is preferable.

  When the excreta absorbing sheet 30 is used, the flap 10 is raised to the wall 16 side with the joint 10s as a base point. When a large amount of urine is scattered to the liquid-impermeable flap 10, the urine falls down through the flap 10, but this urine passes through the surface sheet 2 from the joint 10 s and is absorbed by the absorbent core 4. . Therefore, it is difficult for the urine flowing down through the flap 10 to flow out of the absorption mat 1a.

  As described above, when the top sheet 2 and the flap 10 are continuously joined in the Y direction at the joint 10s, urine that has flowed down along the flap 10 spreads in the Y direction along the joint 10s. Since the absorbent core 4 absorbs the urine that has flowed down, it is difficult for the urine to fall outside the absorbent mat 1s.

  However, in the joint portion 10s, the topsheet 2 and the flap 10 may be joined partially (jumped) with an interval in the Y direction. In this case, a pocket is formed between the flap 10 and the surface sheet 2 that are not joined, and urine that has flowed down through the flap 10 flows into the pocket and passes through the surface sheet 2. The absorbent core 4 is absorbed. Therefore, scattering of urine flowing down through the flap 10 can be prevented.

  Excrement absorption sheet 30A shown in FIG. 12 is obtained by deforming excrement absorption sheet 1 shown in FIG. In the excrement absorbing sheet 30A, the flap 10 formed by extending the top sheet 2 and the back sheet 3 to the same position is the edge of the absorbent mat 1a as in the excrement absorbing sheet 30 shown in FIG. The front surface 1s of the topsheet 2 that is folded and covers the absorbent core 4 at the joint 10s and the flap 10 are joined. In this case, since the surface of the flap 10 on the liquid receiving side is made of the same non-woven fabric as the top sheet 2, the urine that has jumped to the flap 10 flows relatively slowly toward the absorption mat 1a and is scattered. It becomes difficult to be surely absorbed by the absorbent mat 1a.

  Excrement absorption sheet 30B shown in FIG. 13 is obtained by deforming excrement absorption sheet 1 shown in FIG. In the excreta absorbing sheet 30 </ b> B, the liquid-impermeable sheet 9 is bonded to the surface 1 s of the surface sheet 2 that covers the absorbent core 4. In this case, the liquid-impermeable sheet 9 rises upward from the joint 9s as a starting point to form a flap, and the same effect as the excreta absorbing sheet shown in FIGS. 11 and 12 can be obtained. In this case, the end 9a of the liquid-impermeable sheet 9 is extended in the X direction to a position where the end 2b of the topsheet 2 and the end 3b of the backsheet 3 are located, for example, FIG. As shown in FIG. 10, the sheets may be joined to prevent leakage from the end portion.

  Moreover, as shown in FIG. 13, when forming a flap with the liquid-impermeable sheet 9 separate from the back sheet 3, a nonwoven fabric is joined to the liquid-receiving side of the liquid-impermeable sheet 9, You may enable it to prevent scattering.

  11 and 12, the excrement absorbing sheets 30 and 30 </ b> A are formed on the surface of the top sheet 2 that covers the absorbing core 4 by lifting the back sheet 3 up to the absorbing core 4 in the manufacturing method shown in FIG. 5. It can manufacture by adding the process to join. Moreover, in the manufacturing method shown in FIG. 6, the surface sheet 2 which joined the surface sheet 2 and the back surface sheet 3 up to the top of the absorption core 4, and the surface sheet 2 which covers the absorption core 4, and the said surface sheet raised up manually It can be manufactured by adding a process of joining.

Figure 14 is shows a reference example of excrement-absorbing sheet. As a manufacturing method of this reference example, the back sheet 3 formed of a tube-like film or the like is folded so as to be flat (the tube is flattened) and sent in the MD direction in the same manner as shown in FIG. The absorbent core 4 is placed on the back sheet 3, the top sheet 2 is supplied from above, and the surface of the back sheet 3 and the top sheet 2 are bonded and joined in the peripheral region outside the absorbent core 4. . And it cut | disconnects to each dimension and the excrement absorption sheet 1 is completed.

  At the time of use, the tube-like back sheet 3 is cut along a cutting line CLa at a position offset to one side, and the cut back sheet 3 is developed to the side, thereby FIG. 1, FIG. 2, FIG. Similarly to the above, the flap 10 extending from one side of the absorbent mat 1a to the side can be formed. This excrement absorption sheet 1 can be used as an excrement absorption sheet for pets as shown in FIG.

  Moreover, when the tube-like back surface sheet 3 is cut along a cutting line CLb at the center in the width direction in FIG. 14, an optimal structure is obtained as a bed excrement absorbing sheet (bed sheet) for nursing care or the like. That is, the absorbent mat 1a is laid on a mat or a sheet on the bed and the flaps on both sides are wound around the sheet or the mat, thereby making it easy to prevent the displacement of the absorbent mat 1a on the bed. This type of bed excreta absorbing sheet 1 can be used for nursing care, puerperal use, and the like.

  This excrement absorbing sheet is formed so that the absorbent mat 1a having the absorbent core 4 has an area that is the same as or slightly shorter than the width of the mat on the bed. When the back sheet 3 cut along the center cutting line CLb is unfolded, the back sheet 3 becomes a flap protruding to both sides of the absorbent mat 1a. The extension length of the flap is preferably 0.3 times or more, more preferably 0.5 times or more and 2 times or less the width dimension of the absorbent mat 1a.

  Moreover, when manufacturing the said excrement absorption sheet | seat for care, in the state of FIG. 14, the back surface sheet 3 is folded on the surface sheet 2 which covers the absorption core 4, and a surface sheet, the back surface sheet 3, May be joined. In the excreta absorbing sheet for care manufactured by this method, the flaps extending from both sides of the absorbent mat 1a extend from the surface of the top sheet 2 covering the absorbent core 4 as a starting point. When this excrement absorbing sheet for care is used, excrement, for example, urine given to the portion of the surface sheet 2 covering the absorbent core 4 can be dammed up at the joint between the surface sheet 2 and the flap, Urine or the like is less likely to flow out to the flaps on both sides.

  In addition, the excreta absorbing sheet of the present invention can also be used as a drip sheet for transportation such as cut flowers.
