Description

  The present invention relates to an absorbent auxiliary pad and a method for using the same.

  In general, adult paper diapers include a tape-stop type, a pants type, and the like, and these paper diapers are appropriately selected and used according to the necessity of nursing care for excretion of a user. These absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the two sheets. By adopting such a configuration, bodily fluids such as urine pass through the top sheet of the absorbent article, are absorbed by the absorber, and are not leaked to the outside by the back sheet.

  By the way, a tape-type or pants-type paper diaper (hereinafter, referred to as a "tape-type paper diaper") may be used alone or in combination with a urine absorbing pad inside. At present, it is almost always used in combination with a urine absorbing pad, and the urine absorbing pad is stacked on a top sheet. This is because the cost per one piece of disposable diaper is high, and after excrement is absorbed and held by the urine absorbing pad which is inexpensive compared with the disposable diaper such as a tape stopper type, only the urine absorbing pad is replaced. This is because even after excretion, it is not necessary to replace a more expensive paper diaper such as a tape stopper type, and the absorbent article can be used economically at a low cost.

  Here, the urine collecting pad has various sizes and shapes according to the amount of urine, and can reliably absorb excreted urine to prevent leakage. However, for loose stool, watery stool, and diarrhea stool (hereinafter referred to as loose stool, etc.), the absorbency is insufficient, and loose stool may leak to the outside of a disposable diaper such as a urine absorbing pad and a tape-stopping type. Therefore, a urine absorbing pad for preventing loose stools from leaking has been studied.

  As a urine absorbing pad for preventing leakage of loose stools etc., for example, in Patent Document 1, at least a urine absorbing pad provided with a top sheet, a back sheet, an absorber, and a three-dimensional gather, In a range behind the front end of the crotch portion, a portion extending to the side from the projecting portion of the three-dimensional gather is provided with a cup portion that is concave in a cup shape when viewed from the clothing side surface. A urine absorbing pad is disclosed.

JP 2014-45980 A

  Also in the urine absorbing pad described in Patent Document 1, when a large amount of loose stool or the like is excreted, loose stool or the like leaks from a leak-prone portion of the urine absorbing pad to the paper diaper, and loose stool or the like from the paper diaper to clothes or bedding. There is still a high possibility of leakage.

  In addition, the urine absorbing pad is used as a supplement to a disposable diaper, but because it is intended to prevent leakage of loose stool and the like in a wide range, the size is inevitably increased, so that the cost of raw materials increases, and As a result, there was a problem that they were not sufficiently satisfied from the viewpoint of cost.

  Therefore, in one aspect, an object of the present invention is to reduce the possibility of leakage of loose stools and the like while reducing costs.

As shown in FIGS. 3 and 4, the absorbent auxiliary pad 1 of the present invention can be directly arranged on a tape-type disposable diaper 40. Alternatively, as shown in FIGS. The urine absorbing pad 50 can be attached to the disposable diaper 40 of a type or the like, and can be arranged on the body side of the urine absorbing pad 50. As shown in FIG. 1A, the absorbent auxiliary pad 1 is composed of an absorbent body 20 and a liquid-permeable surface material 30, has a flexible columnar shape, and has at least a longitudinal side surface of the absorbent body 20. Is covered with a surface material 30 and is disposed at an end of an absorbent article such as a paper diaper 40 of a tape fixing type or the like and a urine absorbing pad 50. For this reason, as shown in FIGS. 3 to 6, the absorbent auxiliary pad 1 is provided with a urination area and a defecation area located at the crotch part b of an absorbent article such as a paper diaper 40 such as a tape fixing type or a urine absorbing pad 50. By arranging in a substantially U-shape so as to surround from the front part a to the rear part c and to extend along the inside of the three-dimensional gather 41 of the paper diaper 40 such as a tape fixing type and the three-dimensional gather 51 of the urine absorbing pad 50, The auxiliary pad 1 blocks loose stool and the like, and can prevent leakage of loose stool and the like from the absorbent article. Further, since the absorbent auxiliary pad 1 of the present invention has a simple configuration including the absorber 20 and the surface material 30, the raw material cost and the processing cost can be reduced.

  The cross-sectional shape in the short direction of the absorbent auxiliary pad 1 is substantially rectangular or substantially circular from the viewpoint of fit. The longitudinal dimension (see L1 in FIG. 1A) of the absorbent auxiliary pad 1 is 800 mm or more and 1500 mm or less, and preferably 1000 mm or more and 1200 mm or less. The outer circumference (see L2 in FIG. 2) is 90 mm or more and 250 mm or less. By setting the length in the longitudinal direction and the outer circumference of the cross section in the short direction of the absorbent auxiliary pad 1 within the above range, the absorbent auxiliary pad 1 may be used as it is, or may be folded and used. According to the size and shape, it is possible to provide the absorbent auxiliary pad 1 that can appropriately prevent loose stools and the like from leaking.

(Compression rate)
The unloaded thickness (hereinafter referred to as “thickness before compression”) of the absorbent auxiliary pad 1 of the present invention is preferably 15 mm or more and 35 mm or less, more preferably 20 mm or more and 30 mm or less. Further, an acrylic plate having a vertical and horizontal dimension of 50 mm is placed on the absorbent auxiliary pad 1, and the thickness of the absorbent auxiliary pad 1 in a state where a weight of 688 g is placed on the acrylic plate (hereinafter, referred to as “absorbent auxiliary pad 1”). The “thickness after compression” is preferably 5 mm or more and 15 mm or less, and more preferably 8 mm or more and 10 mm or less. Further, the numerical value calculated by the formula of {thickness before compression (mm) −thickness after compression (mm)} / thickness before compression (mm) × 100 is calculated as the compression ratio of the absorbent auxiliary pad 1 ( %), And the compression ratio (%) is preferably 50% or more and 80% or less, and more preferably 60% or more and 70% or less from the viewpoint of fit. By setting the thickness and the compression ratio before and after compression to the above ranges, the absorbent auxiliary pad 1 fits the body under body pressure without a gap, and can effectively prevent leakage of loose stools and the like, In addition, it is possible to prevent pain and decubitus when worn.

[Absorber]
As the base material of the absorber 20 used in the present invention, a fiber aggregate made of tow is used. The fiber aggregate made of tow is an aggregate of long fiber filaments obtained by opening the tow, and is bundled so that the orientation directions of long fibers are aligned. In the present invention, it is preferable to dispose the long fibers so that the orientation direction is the longitudinal direction of the absorbent auxiliary pad 1. For example, a fiber aggregate composed of a bundle of long fibers can be manufactured by opening a continuous filament tow and cutting the tow to an appropriate length.

  As the base material of the fiber assembly composed of tow, natural cellulose derived from cotton or the like, regenerated cellulose such as rayon, cellulose acetate, polyethylene, polypropylene, PET, or the like can be used, and among these, derived from cotton or the like It is preferable to use regenerated cellulose such as natural cellulose or rayon, or cellulose acetate, and it is more preferable to use cellulose acetate which can easily obtain bulkiness and can impart flexibility and flexibility to the absorber 20.

  Further, in the fiber aggregate made of tow, since the entanglement between the fibers is weak, it is preferable to use a binder for the purpose of fusing and fixing the entanglement. As the binder, triacetin or the like can be used.

The basis weight of the fiber assembly made of tow is preferably 100 g / m ² or more and 800 g / m ² or less in order to achieve both leakage prevention and flexibility.

  In addition, the absorber 20 contains a superabsorbent polymer (SAP) in addition to the fiber assembly made of tow.

The superabsorbent polymer (SAP) is not particularly limited as long as it can absorb bodily fluids and prevent backflow, and can be used in combination with sodium polyacrylate, polyaspartate, and (starch-acrylic acid) graft. Polymers formed from materials such as polymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers and saponified products thereof can be used. Among them, sodium polyacrylate-based copolymer is preferable from the viewpoint of the amount of absorption per weight. When the absorbent 20 contains SAP, the amount of SAP of the absorbent 20 is preferably 500 g / m ² or less so as not to impair the absorption performance and the touch. In addition, from the viewpoint of feel, absorption speed, and absorption amount, the weight of the SAP based on the weight of the absorber 20 is preferably 50% by mass or less.
At the time of mixing, the form of the fiber assembly made of tow and the SAP may be formed by mixing SAP particles with the fiber assembly made of tow. At this time, preferably, the fiber aggregate composed of the tow and the superabsorbent polymer are almost uniformly mixed. When mixed substantially uniformly, urine, loose stool, and the like can be uniformly absorbed from any location and any surface of the absorber 20. For example, if there is a portion where the amount of the superabsorbent polymer is small, the absorption of urine or loose stool or the like at the portion may be insufficient, and urine or loose stool may leak. In addition, since the location where the density of the superabsorbent polymer is high absorbs urine and loose stool significantly more than other locations, the thickness of the absorber 20 after absorption becomes uneven.
It should be noted that the substantially uniformly mixed state refers to, for example, a state in which the superabsorbent polymer and fluff pulp are mixed and exist in any of the X, Y, and Z directions (only fluff pulp). Is not included). In a state of being substantially uniformly mixed, for example, when the absorber 20 is divided into 5 mm squares, it is desirable that all cubes contain both the superabsorbent polymer and the fluff pulp.

[Surface material]
The surface material 30 allows the body fluid to pass quickly toward the absorber 20, and covers at least a longitudinal side surface of the absorber 20. Since the surface material 30 is a sheet that comes into contact with the skin, it has a soft feel and does not irritate the skin, for example, a composite in which a thermal bond nonwoven fabric, a spun bond nonwoven fabric, and a thermal bond / spun bond are laminated. It is formed from a material such as a nonwoven fabric, an open film such as an open polyethylene film, a foam film such as polyethylene foam or urethane foam, or a composite sheet obtained by laminating these. The surface material 30 may be a single layer or a plurality of layers, and may have a large number of through-holes for imparting dry touch properties. The surface material 30 used in the present invention is preferably a hydrophilic thermal bond nonwoven fabric or a hydrophilic spunbond nonwoven fabric. As the material of the nonwoven fabric, synthetic fibers such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton can be used.

  As shown in FIG. 1A, the surface material 30 has a linear first bonding portion 31 in the longitudinal direction, and the surface material 30 is bonded by the bonding portion, and the short side direction of the absorber 20. Side can be covered. The bonding of the surface material 30 can be performed by a known method such as heat sealing, ultrasonic sealing, and hot melt. Further, as shown in FIG. 1B, it is preferable that both end portions in the longitudinal direction of the surface material 30 are closed by the second joining portions 32, and the surface material 30 covers the entire absorber 20. That is, the surface material 30 may further cover the side surface in the longitudinal direction of the absorber 20.

Further, the basis weight of the surface material 30 is preferably 15 g / m ² or more and 200 g / m ² or less from the viewpoint of workability and strength. A lotion, an antioxidant, an anti-inflammatory component, a pH adjuster, an antibacterial agent, a humectant, or the like may be applied to the surface material 30 in order to reduce irritation to the skin.

(Locking means)
Further, the surface material 30 may have a locking means for locking both ends in the longitudinal direction of the absorbent auxiliary pad 1 at at least one place. By locking both ends in the longitudinal direction by the locking means, the absorbent auxiliary pad 1 can be arranged on the absorbent article in an O-shape. By arranging the absorbent auxiliary pad 1 in an O-shape, it is possible to prevent loose stools and the like from leaking forward when in the lateral position. Note that a hook member, an adhesive, or the like can be used as the locking means.

(Fixing means)
Further, the surface material 30 may have a fixing means for fixing the absorbent auxiliary pad 1 to the surface of the absorbent article in at least one place. As the fixing means, a hook member, an adhesive or the like can be used. Further, it may have a release sheet for protecting the fixing means, and this release sheet may be integrated with the packaging sheet of the absorbent auxiliary pad 1.

<How to use the absorbent auxiliary pad>
A method of using the absorbent auxiliary pad 1 of the present invention will be described with reference to FIGS. As shown in FIGS. 3 and 4, the absorbent auxiliary pad 1 of the present invention can be directly arranged on a disposable diaper 40 such as a tape fixing type which is an absorbent article. Specifically, the urinal area and the defecation area located at the crotch part b on the top sheet 42 of the tape-type disposable diaper 40 are surrounded from the front part a to the rear part c. Are arranged in a substantially U-shape along the inside of the three-dimensional gather 41. By arranging the absorbent auxiliary pad 1 in this way, the absorbent auxiliary pad 1 can block loose stool and the like, and can prevent leakage of loose stool and the like from the paper diaper 40 such as a tape-stop type. As shown in FIGS. 5 and 6, the absorbent auxiliary pad 1 of the present invention can also be used when a paper diaper 40 such as a tape fixing type and a urine absorbing pad 50 are used in combination. Specifically, a urine absorbing pad 50, which is an absorbent article, is attached to the body side of the top sheet 42 of the paper diaper 40 such as a tape-stopping type, and the absorbent auxiliary is attached to the body side of the top sheet 52 of the urine absorbing pad 50. The pad 1 is arranged. Also in this case, the three-dimensional gathers 41 of the paper diaper 40 such as a tape-stopping type are formed so as to surround the urination area and the defecation area located at the crotch part b on the top sheet 52 of the urine absorbing pad 50 from the front part a to the rear part c. When the urine absorbing pad 50 includes the three-dimensional gathers 51, the urine absorbing pad 50 is arranged in a substantially U-shape so as to extend along the inside of the three-dimensional gathers 51. By arranging the absorbent auxiliary pad 1 in this way, the absorbent auxiliary pad 1 can block loose stool and the like, and prevent leakage of loose stool and the like from the urine absorbing pad 50 to the paper diaper 40 such as a tape stop type. it can.

<Effect of absorbent auxiliary pad>
As described above, the absorbent auxiliary pad 1 of the present invention is provided at the end of an absorbent article such as a paper diaper or a urine absorbing pad such as a tape fixing type, for example, a urination area located at the crotch part b of the absorbent article and By surrounding the defecation area from the front part a to the rear part c and along the inside of the three-dimensional gathers of the absorbent article, it is arranged in a substantially U-shape, so that the absorbent auxiliary pad blocks soft stools and the like, Leakage of loose stools and the like from articles can be prevented.

  Further, since the absorbent auxiliary pad 1 of the present invention has a simple configuration in which the absorbent body 20 is covered with the surface material 30, the raw material cost and the processing cost can be reduced. Furthermore, by setting the length of the absorbent auxiliary pad 1 in the longitudinal direction and the outer circumference of the cross-section in the lateral direction of the absorbent auxiliary pad 1 within the above range, the shape, size, and shape of the absorbent article to be worn can be adjusted. In addition, it is possible to provide an absorptive auxiliary pad that can appropriately prevent leakage of loose stool and the like. In addition, the use of the fiber assembly made of the tow is excellent in flexibility and improves followability to the body, so that the burden on the user is reduced. Fitting is improved because it is easily formed by folding or the like according to the user's body. When forming a U-shape, compared to a conventional auxiliary pad using a fluff or the like, the thickness of the R portion or the right-angled portion is less likely to be increased, and compression is also easier, so that a gap is formed and it is harder to leak. Since the body fluid has good diffusion performance and is mixed with a highly absorbent polymer, it also has an excellent effect of preventing leakage.

  Thus, according to the absorbent auxiliary pad 1 of the present invention, it is possible to appropriately prevent loose stool and the like from leaking, and to realize cost reduction.

  Next, with reference to FIGS. 7A to 7C and Table 1, further effects of the absorbent auxiliary pad 1 of the present invention will be described.

  7A to 7C are explanatory diagrams of characteristics when the absorbent auxiliary pad 1 of the present invention is bent at a right angle, FIG. 7A shows a state before bending, and FIG. 7B shows a state at a right angle. FIG. 7C is a sectional view taken along line PP of FIG. 7B. Table 1 is a table summarizing the relationship between the thicknesses H1 and H2 shown in FIG. 7B, and shows a comparison between the comparative product and the invention product. The unit of the numerical values in Table 1 is mm unless otherwise specified.

The thicknesses H1 and H2 shown in FIG. 7B were measured when no pressure was applied and when a predetermined pressure (here, 35 g / cm ² ) was applied to the comparative product and the invention product. Note that the thickness under a load of 35 g / cm ² is obtained as a value obtained by subtracting the height of the predetermined position of the weight itself from the height of the predetermined position of the weight in a state where the weight is placed on the absorbent auxiliary pad 1. ing.

  The difference between the comparative product and the invention is the material of the absorber. The inventive absorber comprises tow and a superabsorbent polymer, while the comparative absorber comprises fluff pulp instead of tow. That is, the comparative absorbent body is made of only fluff pulp.

  When the absorbent auxiliary pad is bent 90 degrees in the XY plane as shown by the arrow R in FIG. 7A, the state shown in FIG. 7B is obtained. At this time, the absorbent auxiliary pad has a non-bent portion 90 and a bent portion 91. Since the inside of the non-bent portion 90 is not deformed, the upper side in the Z direction is substantially flat as shown in FIG. 7C. On the other hand, since the inside of the bent portion 91 is significantly deformed, the upper side in the Z direction becomes convex as shown in FIG. 7C. That is, the bent portion 91 has a large thickness in the Z direction. Here, when the thickness in the Z direction in the state of being bent at a right angle is H1 at the non-bent portion 90 and H2 at the bent portion 91, H1 and H2 were measured. The results are shown in Table 1. Table 1 also shows H2 / H1, (H2-H1) / H1 in addition to H1 and H2. Table 2 shows the outline of the configurations of the invention product and the comparison product shown in Table 1.

As shown in Table 1, under no load (0 g / cm ² ), in the comparative product, the thickness H2 of the bent portion 91 in the direction perpendicular to the bending direction is less than twice the thickness H1 of the non-bent portion 90. On the contrary, in the invention, the thickness H2 of the bent portion 91 in the direction perpendicular to the bending direction is not more than twice the thickness H1 of the non-bent portion 90. Also, under the load (35 g / cm2), in the comparative product, the thickness H2 of the bent portion 91 in the direction perpendicular to the bending direction does not become 1.5 times or less the thickness H1 of the non-bent portion 90. In the invention, the thickness H2 of the bent portion 91 in the direction perpendicular to the bending direction is 1.5 times or less the thickness H1 of the non-bent portion 90. The compression ratio of the comparative product was 48%, whereas the compression ratio of the invention product was 66%.

By the way, if the difference between the height of the bent portion and the height of the non-bent portion is large, a gap is likely to be formed between the wearer and the absorbent auxiliary pad around the bent portion, and urine and loose stool etc. may be collected on the urine absorbing pad and tape. It may leak to the outside of disposable diapers such as stop type. In addition, particularly in a sitting position or a supine position, a thick portion having a bent portion bites into a wearer's skin, etc., thereby causing a sense of incongruity and inferior wearing comfort.
In this regard, according to the absorbent auxiliary pad 1 of the present invention, the amount of change in thickness due to bending can be reduced even when bending and arranging as described above. As a result, the possibility that urine or loose stool leaks from between the wearer and the absorbent auxiliary pad is reduced, and the wearing comfort can be enhanced.

As described above, each embodiment has been described in detail. However, the present invention is not limited to a specific embodiment, and various modifications and changes can be made within the scope described in the claims. It is also possible to combine all or a plurality of the components of the above-described embodiment.
