Definitions
- the present invention relates to an absorbent article having a liquid absorption function, and more particularly to an absorbent article suitable for use as a urine collecting pad.
- the urine absorbing pad is used in preparation for incontinence.
- the form of force incontinence is not uniform. Incontinence can vary from incontinence that releases a large amount of urine to incontinence that only excretes a small amount of urine. For example, light incontinence during abdominal pressure that occurs when sneezing or the like causes a small amount of urine to be excreted, so that the urinary force is not excreted vigorously and easily moves through the skin. For this reason, urine that travels through the skin cannot be reliably transferred to the absorber unless the urine collection pad and the body excretion part are in close contact with each other, and easily leaks to the outside of the urine collection pad. .
- an absorbent article used as a urine-absorbing pad needs to be able to quickly and reliably absorb both urine excreted in a small amount and urine excreted in a large amount.
- absorbent articles used as sanitary napkins The same applies to absorbent articles used as sanitary napkins.
- Absorbent articles used as urine absorbing pads generally include a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body positioned between the top sheet and the back sheet.
- the absorbent body is formed by mixing pulp and highly water-absorbent fat.
- a technique for capturing a small amount of urine is disclosed in, for example, absorbent articles described in Japanese Patent No. 3442929 and Japanese Patent Laid-Open No. 2002-320638.
- the bulging portion itself formed of a liquid-absorbent sheet directly contacts the skin and urine, etc. If the body fluid is first absorbed, if a large amount of body fluid is excreted, a large amount of fluid tends to accumulate on both sides of the raised portion. In addition, urine that has been absorbed by the ridges and absorbed enough is absorbed by the absorbent body of the absorbent article body. Even in this case, the absorption rate of the pulp in the absorbent body of the absorbent article main body cannot follow the flow of the body fluid, and there is a problem that the body fluid tends to flow to the left and right outer sides of the absorbent article.
- the present invention solves the above-mentioned conventional problems, and even when a large amount of body fluid is received, the body fluid is prevented from staying on the top sheet, and the body fluid is leaked to the outside.
- An object of the present invention is to provide an absorbent article that can be reliably captured.
- the present inventor makes the absorbent body quickly without causing urine to stay on the surface by widely diffusing body fluid on the top sheet.
- the present inventors have found that it can be migrated and have completed the present invention.
- the absorbent article including the absorber and the top sheet is provided with a bulging means including an elastic member, and the top sheet is provided with a region that does not adhere to other constituent members.
- the present invention provides the following.
- a vertically long absorbent article having a longitudinal direction and a transverse direction, a liquid-permeable top sheet, a liquid-impermeable back sheet, the top sheet, and the back sheet Between the top sheet and the absorbent body, and disposed in a band shape along the longitudinal center line of the absorbent article.
- Bulging means for bulging the vicinity of the center line of the sheet, and the bulging means supports the top sheet and a fixing portion fixed to the absorber and serving as a base of the bulging means.
- a liquid permeable member that includes a top surface portion, and a standing portion that connects the fixing portion and the top surface portion and rises in the direction of the force toward the body when worn, and the top surface portion absorbs the absorption
- a plurality of elastic members arranged to extend in the longitudinal direction in parallel with the center line of the absorbent article, and the top sheet is located between the center line of the top surface portion and both side edges of the absorbent article.
- An absorbent article having a non-adhesive region.
- the top sheet is not bonded to other constituent members between the longitudinal center portion of the bulging means and the side edge portion of the absorbent article, and is in a free state.
- the bulging means is a force that contracts due to the shrinkage stress at the portion where the elastic member is disposed.
- the shrinkage force also acts on the top sheet. Therefore, a wrinkle parallel to the width direction appears on the top sheet in the portion located on the bulging means.
- the present invention transmits a sheet on the top sheet that receives a large amount of body fluid.
- body fluid is quickly diffused.
- the absorbent capacity of the absorber is saturated in that portion, leakage occurs.
- the top sheet is attached with a certain amount of clearance in order to make it easier to develop wrinkles on the top sheet.
- the diagonal sheet enters the top sheet. For this reason, it becomes possible to prevent the occurrence of a wrinkle that can only be spread in the width direction as in the prior art, and that the body fluid can be diffused only on both sides of the body fluid excretion part.
- the top sheet includes a first adhesive region bonded to the top surface portion, and a second adhesive region for adhering along the vicinity of both side edges in the longitudinal direction of the absorbent article. And the first adhesive region to the second adhesive region in order to change the angle of the oblique sheet appearing by force from the top surface portion toward the both side edges with respect to the lateral direction.
- the angle of the crease appearing on the top sheet is adjusted by appropriately adjusting the adhesion area between the top sheet as the first adhesion area and the top surface portion of the bulging means. It has become possible to do. For example, if the first bonding area is widened, the angle at which the sheet is slanted can be tightened as a whole, and if the first bonding area is narrowed, the angle of the sheet can be gradually increased. I'll do it.
- the leakage preventing means is provided along the vicinity of both side edges in the longitudinal direction of the absorbent article, for example, as a side gather described later. This prevents bodily fluids excreted in large quantities, such as urine, from leaking out from the side edges of the absorbent article in the longitudinal direction.
- the second adhesive region of the top sheet is disposed, for example, near the base of the side gather, along the vicinity of both side edges in the longitudinal direction of the absorbent article without impairing the function of the side gather. In other words, it is important that the second adhesion region of the top sheet is provided so that the body fluid blocked by the side gathers can be smoothly guided to the absorber through the top sheet and the bulging means.
- the second adhesive region of the top sheet is topped with bodily fluids blocked by side gathers that serve as leakage preventing means. It can be arranged so that it can be smoothly led to the absorber through the sheet and the bulging means.
- the top sheet is bonded to the first bonding region bonded to the top surface portion and the fixing portion connected to the absorber in the vicinity of both side edges in the longitudinal direction of the absorbent article.
- the top sheet includes a first adhesive region bonded to the top surface portion, a second adhesive region bonded to the back sheet in the vicinity of both side edges in the longitudinal direction of the absorbent article,
- the absorbent article according to (1) comprising:
- the base sheet in the first adhesion region, is formed on the top sheet on the top surface portion by the elastic member on the top surface portion.
- the top sheet is not bonded to the other component members between the first bonding region and the second bonding region, and is in a free state.
- the above-described base sheet develops into a sheet extending obliquely with a force toward the second bonding region. That is, the second adhesive region in the top sheet contributes to the expression of an oblique sheet that fixes the side edge of the top sheet and extends the first adhesive region force.
- the adhesion region between the top sheet and the top surface portion of the bulging means, the top sheet By providing a free part that is not bonded to the top sheet between the side edge and the bonding region, a sheet entering diagonally on the top sheet is formed. Then, when the body fluid excreted through the skin is transmitted, the body fluid is also induced (diffused) on both the front and back sides of the excretion part, and is guided to the absorber located under the top sheet to be absorbed. it can.
- the point of absorption of the body force increases due to the diffusion of the body fluid, even when a large amount of body fluid is excreted, the body fluid is quickly diffused and absorbed in an oblique direction, so that the amount of body fluid that accumulates on the surface is reduced. It is possible to reduce the outside leakage.
- the absorption area can be increased, the absorption capacity per unit area can be increased, so that the amount of body fluid that is wet-backed (returned) can be reduced.

- the absorbent article 1 of the present embodiment is configured such that a large number of curved lines for rapidly diffusing urine excreted on the top sheet 11 in contact with the body side are expressed. . For this reason, even when a relatively large amount of urine is excreted at a time due to urge incontinence, the function of diffusing and absorbing this urine can be exhibited.
- the absorbent article 1 has a concave curved surface shape that is recessed on the surface of the liquid-receiving side so that it is easy to be worn by the wearer and hardly leaks.
- This absorbent article 1 has a longitudinal shape that is longer than the dimension in the width direction (X direction), which is the short direction, in the longitudinal direction (Y direction), which is the longitudinal direction.
- the length dimension is about 300-500mm
- the width dimension is about 100-200mm.
- the thickness is about 5 to 30 mm when worn between the underwear and the body.
- the absorbent article 1 is disposed between a liquid-permeable top sheet 11, a liquid-impermeable back sheet 12, and the top sheet 11 and the back sheet 12. It has an absorber 13 that absorbs and retains. Furthermore, a swelling means 3 comprising a liquid permeable sheet 30 provided so as to project along the center line O in the longitudinal direction of the support 2 comprising the absorber 13 is provided.
- the bulging means 3 is composed of a series of liquid-permeable sheets 30, and includes a fixing part 31 that is fixed to the support 2, a standing part 32 that raises the bulging means 3, and a top surface part that is in close contact with the body when worn. It consists of 33 and
- the liquid permeable sheet 30 is folded in two on both sides across the longitudinal center line O, and the elastic member is interposed between the folded liquid permeable sheets 30. 34 is sandwiched, and the folded inner surface of the liquid-permeable sheet 30 and the elastic member 34 are bonded and fixed with a hot-melt adhesive.
- Four elastic members 34 are provided on one side of the longitudinal center line O and four on the other side, and are liquid permeable in the longitudinal direction 1.2 to 2 times longer. It is fixed to the sheet 30. A center gather is formed by the contraction stress of the elastic member 34, and the upright portion 32 is erected.
- This elastic member 34 is not disposed over the entire longitudinal direction of the bulging means 3, but is disposed only in the first region L1, as shown in FIG. 4, and in the second region L2 behind it. Is not placed.
- the length of the first region L1 is about 130 to 23 Omm
- the length of the second region L2 is set shorter than the length of the first region L1.
- the first region L1 and the second region L2 may have the same length dimension, or the second region L2 may be longer.
- a liquid-permeable top sheet 11 is provided on the liquid-receiving surface of the bulging means 3, and covers the liquid-receiving side of the top surface portion 33 containing the elastic member 34.
- the top sheet 11 and the top surface portion 33 are bonded together.
- the second adhesion region l id is provided along the formation region of the side gathers 20 as a leak-proof means.
- the top sheet 11 is bonded to the side gathers 20 which are leakage preventing means located on both side edges in the longitudinal direction of the absorbent body 13, and the absorbent body 13 is located below the top gather 11. It is like this.
- the top sheet 11 also has a non-adhesive region 1 lb and a non-adhesive region 1 lc that are not adhered to any other parts and are in a free state.
- the top sheet 11 since there is no elastic member in the second adhesive region l id, the top sheet 11 remains stretched. On the other hand, the top sheet 11 is bonded to the top surface portion 33 and the top sheet 11 is shrunk together with the top surface portion 33 by the elastic member 34 during use in the la bonding area 1 la. To generate a sheet parallel to the width direction.
- the non-adhesive regions 1 lb and 1 lc between the first adhesive region 11a adhered to the top surface portion 33 and the second adhesive region 1 Id adhered at both side edges of the absorber 13 are used.
- the sheet is slanted by being pulled by the contraction of the elastic member 34 of the top surface portion 33. This is because the top sheet 11 of the free part is not affected by the shrinkage in the second adhesive region 1 Id, but is affected by the shrinkage in the first adhesive region 1 la. This is because the adhesive areas l ib and 11c are inclined diagonally.
- the contraction of the top surface portion 33 has a contraction range in which the center portion is contracted from both the position where the elastic member 34 starts to be affected and the position where the top surface 33 ends. For this reason, the distance of contraction becomes longer as the central partial force of the contraction range becomes farther. Therefore, in the non-adhesive areas 1 lb and 1 lc of the top sheet 11, the sheet that enters the parallel line of the central part of the shrinkage range enters the sheet parallel to the width direction of the top surface 33. As the force on the parallel line at the center of the shrinkage range increases, the diagonal sheet enters, and the further away, the longer the top sheet 11 travels, so the angle at which the sheet is inclined becomes tighter.
- the angle of the sheet 11a becomes slanting, and the angle becomes tight as a whole, and conversely, if the range of the first adhesion region 11a is narrowed, the angle becomes loose.
- the preferred range of adhesion between the top sheet 11 and the top surface 33 is at most about the same width as the top surface 33 and at least about one third of the width of the top surface 33. (In this case, the width of the top surface 33 is half the distance between the fulcrums of the side gathers 20. The following dimensions are preferable).

The Moreover, you may form with the resin film which has many liquid permeable holes.
- the top sheet 11 is used that has been concavo-convex shaped so as to shrink toward at least one of the vertical and horizontal directions by squeezing embossing.
- the squeezing embossing is performed in such a manner that a non-woven fabric or a resin film is squeezed between a pair of rolls having uneven portions on the surface.
- the top sheet 11 becomes shrinkable in at least one of the vertical direction and the horizontal direction.
- the bulging means 3 covered with the top sheet 11 can easily increase the surface force of the absorber 13, and the bulging means 3 can be With 11 you can move relatively freely left and right.
