<1. Absorption pad according to one embodiment>
FIG. 1 is a perspective view of an absorbent pad 1 according to an embodiment of the present invention. FIG. 2 is a plan view of the absorbent pad 1 as viewed from the first sheet 11 side. 3 is a cross-sectional view of the absorbent pad 1 as viewed from the position III-III in FIG.

  The absorbent pad 1 is used to assist absorption of urine by a diaper by laying inside the diaper or by inserting it into a gap between the diaper and the wearer's skin. A wearer of a diaper can prevent leakage of urine from the diaper (such as a gap leak or a leaked leak) by using the absorbent pad 1 together with the diaper.

  As shown in FIGS. 1 to 3, the absorbent pad 1 includes a liquid-permeable first sheet 11 and second sheet 12, and two absorbent bodies 21 and 22 sandwiched between the sheets 11 and 12. And a liquid-permeable connecting sheet 41 attached to the first sheet 11. When the urine excreted from the wearer of the diaper comes into contact with the first sheet 11, the second sheet 12, or the connecting sheet 41, the urine passes through these sheets 11, 12, 41, and the absorbent body 21, 22 is absorbed and held.

  The 1st sheet | seat 11, the 2nd sheet | seat 12, and the connection sheet | seat 41 are comprised by the nonwoven fabric using hydrophilic fiber (cellulose, rayon, cotton, etc.), for example. In addition, the first sheet 11 and the second sheet 12 may be formed of a nonwoven fabric that is made liquid permeable by treating the surface of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with a surfactant. Good.

  The absorbers 21 and 22 are each formed in a flat rectangular shape. The absorbers 21 and 22 are arranged so that one end sides of each of the absorbers 21 and 22 are adjacent to each other and are located on substantially the same plane as a whole. One surface (hereinafter referred to as “upper surface”) of the absorbent bodies 21 and 22 is covered with the first sheet 11. The other surfaces (hereinafter referred to as “lower surfaces”) of the absorbent bodies 21 and 22 are covered with the second sheet 12.

  The absorbers 21 and 22 are configured by, for example, a granular polymer absorber distributed in a planar shape. The absorbent bodies 21 and 22 are formed by mixing a mass of hydrophilic fibers such as pulverized pulp fibers and cellulose fibers with a granular polymer absorbent mixed with a paper sheet such as tissue paper or a liquid-permeable nonwoven fabric. It may be coated. The absorbers 21 and 22 may be sheet-like absorbers in which a polymer absorber is fixed between a pair of liquid-permeable sheets via an adhesive.

  In addition, it is preferable that the absorbers 21 and 22 are made of a polymer absorber that does not have pulp in that the absorbers 21 and 22 can be thinned.

  As shown in FIG. 3, the absorbent bodies 21 and 22 are fixed between the first sheet 11 and the second sheet 12 with an adhesive 31. Further, the first sheet 11 and the second sheet 12 are joined to each other via an adhesive 31 in a portion (hereinafter referred to as “gap portion 13”) located between the adjacent absorbent bodies 21 and 22. . In addition, the first sheet 11 and the second sheet 12 are also bonded to each other at the peripheral edge portion 14 via the adhesive 31.

  An adhesive 31 is applied between the first sheet 11 and the second sheet 12 and the absorbers 21 and 22 at a lower density than the gap 13 and the peripheral edge 14. Accordingly, the adhesive 31 prevents the urine from being transmitted from the first sheet 11 or the second sheet 12 to the absorbers 21 and 22.

  As shown in FIGS. 1 to 3, the gap 13 between the first sheet 11 and the second sheet 12 is drawn out to the space on the lower surface side of the absorbent bodies 21 and 22. And the connection sheet | seat 41 is stuck on the upper surface of the 1st sheet | seat 11 so that the gap | interval part 13 may be straddled in the state which made the absorber 21 and the absorber 22 approach mutually. Thereby, the adjacent absorbers 21 and 22 are maintained in an approaching state. As shown in FIG. 3, the connection sheet 41 is attached to the upper surface of the first sheet 11 via the adhesive 32.

  Thus, in this embodiment, the adjacent absorbers 21 and 22 are maintained close to each other. Thereby, the weak part of the absorptive power between the absorber 21 and the absorber 22 is reduced. Therefore, the absorption pad 1 of this embodiment can absorb a wearer's urine favorably. In particular, in the present embodiment, a liquid permeable sheet is used as the connection sheet 41. For this reason, adjoining absorbers 21 and 22 can be made into an approach state, suppressing that connection sheet 41 itself inhibits permeation of urine.

  As shown in FIGS. 1 and 2, the connection sheet 41 has a first perforation 411. The first perforation 411 is formed in a portion of the connection sheet 41 that is not attached to the first sheet 11. Further, the first perforation 411 extends from one end of the connection sheet 41 to the other end along the boundary between the adjacent absorbent bodies 21 and 22.

  The user can cut the connection sheet 41 by breaking the first perforation 411 as necessary. The user does not need to use an instrument such as scissors when cutting the connecting sheet 41. For example, as shown in FIG. 4, when the absorbent pad 1 is pulled outward so as to separate the absorbent body 21 and the absorbent body 22, the first perforation 411 is broken, thereby cutting the connection sheet 41. .

  Thereafter, as shown in FIG. 5, the user can cut the gap 13 between the first sheet 11 and the second sheet 12 with scissors, for example. Thereby, two absorption pads smaller than the absorption pad 1 before cutting can be obtained.

  The absorbent pad 1 that has not been cut can be used, for example, in a relatively wide area inside the diaper. On the other hand, the absorbent pad after cutting can be used, for example, to fill a small gap between the wearer and the diaper.

  As described above, the user can use the absorbent pad 1 in a predetermined size as well as cut it into a small size. That is, the user can select the size of the absorbent pad according to the situation. Thereby, according to a wearer's body shape and the site | part which arrange | positions an absorption pad, the absorption pad of a suitable size can be used without waste.

  Further, as described above, the first sheet 11 and the second sheet 12 are joined to each other at the gap portion 13 and the peripheral portion 14. For this reason, the absorbent pad after cutting is also in a state where the first sheet 11 and the second sheet 12 are joined at the peripheral edge thereof. Therefore, it is possible to prevent the first sheet 11 and the second sheet 12 from opening at the peripheral edge of the absorbent pad after cutting, and the absorbent bodies 21 and 22 from leaking from the peripheral edge of the absorbent pad after cutting. The

  Moreover, the user can also fold and use the absorption pad 1 as shown in FIG. 6 without cutting the connection sheet 41. In this way, since the two absorbers 21 and 22 are laminated, the ability to absorb urine per unit area is improved. For example, the user can fold and arrange the absorbent pad 1 at a location where the amount of urine leakage is large.

  When the absorbent pad 1 is folded as shown in FIG. 6, the connecting sheet 41 is easily folded with the first perforation 411 as a boundary. That is, in the present embodiment, the first perforation 411 plays both a role of facilitating the cutting of the connecting sheet 41 and a role of facilitating the folding of the connecting sheet 41.

  In the present embodiment, the orientation of the fibers of the connection sheet 41 is in the direction along the first perforation 411. Therefore, the user can more easily cut the connection sheet 41 in the direction along the first perforation 411 and can more easily fold the connection sheet 411 with the first perforation 411 as a boundary.

<2. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  For example, a second perforation 15A may be provided in the gap 13A between the first sheet 11A and the second sheet as in the absorbent pad 1A of FIG. The second perforation 15A in FIG. 7 extends from one end of the first sheet 11A and the second sheet to the other end along the boundary between the adjacent absorbers 21A and 22A. By doing so, the first sheet 11A and the second sheet can be easily cut by breaking the second perforation 15A. As in FIG. 4, the user can cut the first sheet 11 </ b> A and the second sheet by pulling the absorbent pad 1 </ b> A outward to cut the connection sheet 41 </ b> A and then pulling the absorbent pad 1 </ b> A further outward. . Therefore, it is not necessary to use a tool such as scissors not only for cutting the connecting sheet 41A but also for cutting the first sheet 11A and the second sheet.

  When the second perforation 15A is provided, it is desirable that the orientation of the fibers of the first sheet 11A and the second sheet be in a direction along the second perforation 15A. By doing so, the user can more easily cut the first sheet 11A and the second sheet in the direction along the second perforation 15A.

  However, the orientation of the fibers of the first sheet, the second sheet, and the connection sheet is not necessarily the direction along the first perforation or the second perforation. For example, the orientation of the fibers of the first sheet, the second sheet, and the connecting sheet may be a direction orthogonal to the first perforation or the second perforation.

  In the above embodiment, the connecting sheet 41 is provided over the entire width of the first sheet 11. However, the connecting sheet 41 may be provided only in a part of the first sheet 11 in the width direction. . That is, the length of the connection sheet 41 in the direction along the first perforation 411 may be shorter than the length of the first sheet 11 in the same direction. However, in order to stably maintain the absorbers 21 and 22 in the approaching state, the length of the connecting sheet 41 in the direction along the first perforation 411 is longer than the length of the absorbers 21 and 22 in the same direction. It is desirable.

  In the above embodiment, the two absorbent bodies 21 and 22 are disposed between the first sheet 11 and the second sheet 12, but between the first sheet 11 and the second sheet 12, Three or more absorbers may be arranged. For example, three absorbent bodies 21B to 23B may be disposed between the first sheet 11B and the second sheet as in the absorbent pad 1B of FIG.

  In the example of FIG. 8, between the absorber 21B and the absorber 22B, the first sheet 11B and the second sheet are pulled out to the lower surface side, and the connecting sheet 41B that maintains the absorber 21B and the absorber 22B in the approaching state. Is attached to the upper surface of the first sheet 11B. Further, between the absorbent body 22B and the absorbent body 23B, the first sheet 11B and the second sheet are pulled out to the lower surface side, and the connecting sheet 42B that maintains the absorbent body 22B and the absorbent body 23B in the close state is the first sheet 11B. It is stuck on the upper surface of the sheet 11B. And the 1st perforation 411B and 421B extended along the boundary of an adjacent absorber are each formed in the connection sheet | seat 41B and the connection sheet | seat 42B.

  If a plurality of absorbers are arranged in a row as shown in FIG. 8, an absorbent pad having a desired length can be obtained by cutting the connecting sheet, the first sheet, and the second sheet at an arbitrary gap. it can. Moreover, since the cutting direction of the connection sheet, the first sheet, and the second sheet is only one direction and the length to be cut is only one side, the cutting operation of the absorbent pad is facilitated.

  Further, when three or more absorbers are arranged, the absorption pad can be partially folded and used. FIG. 9 is a perspective view showing a state in which the absorbent pad 1B of FIG. 8 is folded with the first perforation 421B as a boundary. In the example of FIG. 9, two absorbers 22 </ b> B and 23 </ b> B are stacked among the three absorbers 21 </ b> B to 23 </ b> B included in the absorption pad 1 </ b> B. In this way, for example, two stacked absorbers 22B and 23B are disposed at a location where the amount of urine leakage is large, and the remaining one absorber 21B is disposed at a location where the amount of urine leakage is small. It is possible to use this way.

  Moreover, in said embodiment, although the rectangular absorbers 21 and 22 were used in planar view, the shape of each absorber may be shapes other than a rectangle. For example, two absorbent bodies 21C and 22C having a triangular shape in a plan view may be disposed between the first sheet 11C and the second sheet as in the absorption pad 1C of FIG.

  In the example of FIG. 10, the two absorbers 21 </ b> C and 22 </ b> C have a substantially right-angled isosceles triangle shape in plan view, and are arranged so that the oblique sides are opposed to each other. And between 21 C of absorbers and 22 C of absorbers, the 1st sheet | seat 11C and the 2nd sheet | seat are pulled out to the lower surface side, and the connection sheet | seat 41C which maintains the absorber 21 C and 22 C of absorbers in an approach state is 1st. It is stuck on the upper surface of the sheet 11C. And in the connection sheet | seat 41C, the 1st perforation 411C extended along the boundary of an adjacent absorber is formed.

  As shown in FIG. 10, if the triangular absorbent body is included, the absorbent pad can be cut into a shape including an acute angle. For this reason, the absorbent pad after cutting can be fitted into a narrow gap. For example, as shown in FIG. 11, the cut absorbent pad can be used to fill a gap between the wearer's thigh and diaper.

  Moreover, in said embodiment and modification, although the shape and magnitude | size of the some absorber contained in an absorption pad were the same, two types of absorbers from which a shape and magnitude | size differ in one absorption pad. It may be included. For example, a single absorbent pad may include a rectangular absorber in plan view and a triangular absorber in plan view.

  Moreover, in said embodiment and modification, the 1st sheet | seat and the 2nd sheet | seat were respectively continuous via the gap | interval part. That is, the first sheet and the second sheet were each a single sheet. If each of the first sheet and the second sheet is a single sheet, there is an advantage that the absorbent pad can be manufactured by a simple process. However, the first sheet and the second sheet are not necessarily a single sheet.

  For example, like the absorption pad 1D of FIG. 12, the first sheet and the second sheet may be separated in advance in the gap portion 13D. In the example of FIG. 12, the first sheet 11D is composed of two separate first sheets 111D and 112D. The second sheet 12D includes two separate second sheets 121D and 122D. The absorber 21D is disposed between the first sheet 111D and the second sheet 121D, and the absorber 22D is disposed between the first sheet 112D and the second sheet 122D. In this way, when the absorbent pad 1D is cut and used, only the connecting sheet 41D needs to be cut. Therefore, the cutting operation of the absorbent pad 1D becomes easier.

  Moreover, in said embodiment and modification, although the perforation was provided as a weakening line, the 1st weakening line and 2nd weakening line of this invention are not limited to a perforation. The 1st weakening line and the 2nd weakening line should just weaken the 1st sheet and the 2nd sheet, and make cutting and folding of an absorption pad easy. For example, instead of the perforation, a weakening line by ultrasonic fusion, thermal fusion, embossing, or the like may be formed.

  Moreover, in said embodiment and modification, although the connection sheet was affixed on the upper surface of the 1st sheet via the adhesive agent, the connection sheet of this invention is fixed to the 1st sheet by another method. May be. For example, the connecting sheet may be fixed to the first sheet by heat sealing, stitching, or the like.

  Moreover, although the absorption pad of said embodiment and a modification was used with a diaper and absorbed urine auxiliary, the absorption pad of this invention is used separately from a diaper, Also good. Moreover, the absorption pad of this invention may absorb excretion liquids other than urine.

  Moreover, the absorbent pad of the present invention may be intended for adults or may be intended for infants.
