Description

  The present invention relates to an absorbent article such as a sanitary napkin.

  In general, an absorbent article is known in which an absorbent core is provided between a liquid-permeable top sheet that comes into contact with the wearer's skin and a liquid-impermeable back sheet. Among the absorbent articles, sanitary napkins, in particular, are pressed against the wearer's body by underwear and used so as to fit the wearer's body.

  However, when the sanitary napkin is used, the sanitary napkin may change into the wearer's body shape, for example, depending on the size of the underwear, the state of the elastic member of the underwear, and the posture of the wearer (for example, standing, sitting, or sleeping posture). It may not fit. For example, when the size of the underwear is too large for the wearer, a gap is left between the excretion opening and the sanitary napkin, and body fluid is likely to leak, or the wearer leaks body fluid. I feel anxious about things. On the other hand, for example, when the size of the underwear is too small for the wearer, the sanitary napkin and the body are in close contact with each other, the comfortable wearing feeling is impaired, and the wearer feels uncomfortable when wearing the absorbent article. End up.

  Here, Patent Literature 1 discloses an absorbent article that disperses pressure on a wearer's body. Specifically, the absorbent article described in Patent Document 1 has a two-layer absorbent core containing an absorbent polymer, and a movement auxiliary material made of beads or the like is provided between the two layers of the absorbent core. Yes. When body fluid or the like is absorbed in the absorbent polymer of the absorbent article described in Patent Document 1, a polymer layer having viscosity and elasticity is formed on the surface where the two absorbent cores face each other. And by the movement assistance material which consists of a polymer layer, a bead grain, etc. which were formed, two absorption cores become easy to shift | deviate along the surface which each faces, and the pressure with respect to a wearer's body can be disperse | distributed.

(2) Function of Granular Layer FIG. 5 is a diagram schematically showing the movement of the granular material in the granular layer 60 in plan view. FIG. 5A shows a state in which no pressure is applied to the granular layer 60. FIG. 5B shows a state in which the pressure F in the thickness direction T is applied to the granular layer 60. As shown in FIG. 5 (B), the granular material moves from a high pressure portion where the pressure F is applied to another low pressure portion.

  FIG. 6 is a diagram schematically illustrating the movement of the granular material in the granular layer 60 in a cross-sectional view parallel to the thickness direction T. FIG. 6A shows a state before the pressure F in the thickness direction T is applied to the absorbent article 1 (a state where no pressure is applied). FIG. 6B shows a state where the pressure F in the thickness direction T is applied to the absorbent article 1. As shown in FIG. 6B, the pressure F is applied to the package 63 via the top sheet 10 and the absorbent body 30 (the absorbent core 31 and the core wrap 32). When the package 63 receives a pressure F in the thickness direction T of the absorbent article, the package 63 expands in the thickness direction T, and the granular material wrapped in the package 63 has a high pressure in the granular layer 60. Move from lower to lower. The granular material that has moved to the lower pressure extends the packaging body 63 and pushes up the absorbent body 30 and the topsheet 10 that overlap in a plan view in the thickness direction T. Thus, the granular layer 60 is provided in the absorbent article 1, and the packaging body 63 that wraps the granular body can be expanded, whereby the packaging body 63 is expanded in accordance with the pressure on the granular layer 60, and the granular body is Since the inside of the extended package 63 moves, the fluidity is increased. Thus, the shape of the absorber can be deformed so as to follow the shape of the wearer's body. Therefore, in the wearing state of the absorbent article 1, an uneven shape corresponding to the pressure on the absorbent article 1 is formed on the absorbent body 30 and the top sheet 10, and the absorbent article 1 changes so as to follow the shape of the wearer's body. To do.

  In addition, the pressure with respect to the absorbent article 1 in a wearing state is applied not only in the thickness direction T but also in the width direction W and the longitudinal direction L. Similarly to the case where the pressure in the thickness direction T is applied, even when the pressure in the width direction W and the longitudinal direction L is applied, the granular material in the granular layer 60 moves from the high pressure portion to the low pressure portion.

(3) Configuration of Granular Layer FIG. 7 is a schematic cross-sectional view for explaining the configuration of the granular layer 60. As shown in FIG. 8, the granular layer 60 is provided with a wrapping body 63 that wraps the granular body, and is composed of a plurality of granular sections 61 that are separated by a separation wall 62. In addition, the separation wall 62 may be formed by joining one package body linearly as shown in FIG. 7, or as a planar shape where both are in contact with each other by joining a plurality of separate package bodies. It may be formed.

(4) Absorbent article in the first modified example FIG. 8 is a view of the package 63 and each sheet (the front sheet 10, the back sheet 20, and the core wrap 32) in the extending direction in the first modified example of the embodiment of the present invention. It is a figure which shows an example typically. At least one of the package 63, the top sheet 10, the back sheet 20, and the core wrap 32 in the first modification can be extended in the longitudinal direction L or the width direction W. FIG. 8A shows an example in which the package 63 and the core wrap 32 can be extended in the width direction. FIG. 8B shows an example in which the package 63 can be extended in the longitudinal direction L and the topsheet 10 can be extended in the width direction W. In addition, the part extended in the extendable top sheet 10, back sheet 20, and core wrap 32 should just be a part which overlaps with the granular layer 60 by planar view. According to the absorbent article 1 in the first modified example, the shape of the absorbent article 1 can be made to follow the shape of the wearer's body, and the wearing feeling of the absorbent article 1 can be improved.

(5) Absorbent article in the second modified example FIG. 9 is an illustration of the package 63 and the sheets (the front sheet 10, the back sheet 20, and the core wrap 32) in the extending direction of the second modified example of the embodiment of the present invention. It is a figure which shows an example typically. All of the packaging body 63, the top sheet 10, the back sheet 20, and the core wrap 32 in the second modified example can be extended in the longitudinal direction L or the width direction W, and the extending directions coincide with each other. FIG. 9A shows an example in which the package 63, the top sheet 10, the back sheet 20, and the core wrap 32 can be extended in the width direction W. FIG. 9B shows an example in which the package 63, the top sheet 10, the back sheet 20, and the core wrap 32 can be extended in the longitudinal direction L. In addition, the part extended in the extendable top sheet 10, back sheet 20, and core wrap 32 should just be a part which overlaps with the granular layer 60 by planar view. According to the absorbent article 1 in the second modified example, the shape of the absorbent article 1 can be made to follow the shape of the wearer's body, and the wearing feeling of the absorbent article 1 can be improved.

(6) Action and effect When the granular layer 60 receives pressure in the thickness direction of the absorbent article, a large number of granular bodies contained in the granular layer 60 move in all directions in the granular layer. The granular material moves from a high pressure portion to a low pressure portion in the granular layer.

  The absorbent article 1 of this embodiment is configured to include a granular layer 60 including a stretchable packaging body 63 that wraps a large number of granular bodies.

  When the absorbent article 1 is worn, the pressure from the wearer is applied to the package 63 via the top sheet 10. And as for many granular materials contained in the packaging body 63, the granular material of a part with a high pressure in the packaging body 63 moves toward the part with a low pressure in the packaging body 63. FIG. And the surface sheet 10 is pushed up in the thickness direction by the granular material which moved the inside of the package 63. Thereby, the shape of the absorbent article 1 changes so that the shape of a wearer's body may be followed, and the wearing feeling of the absorbent article 1 can be improved.

  Here, when the packaging body 63 that wraps the granular material is extendable, a portion of the packaging body 63 to which pressure is applied extends and deforms in the direction of the pressure, so that the packaging body 63 that does not stretch is used. In comparison with the above, the pressure applied to the granular material becomes higher. That is, it is possible to increase the number of granular materials that move according to changes in pressure.

  Furthermore, the expandable package 63 is extended by the granular material that has moved from the high pressure portion to the low pressure portion of the package 63. Thereby, compared with the case where the packaging body 63 which does not expand | extend is used, a granular material becomes movable in the range exceeding the size of the packaging body 63 in the state where the pressure is not applied.

  As described above, since the packaging body 63 is extendable, the absorbent article 1 is more worn by the wearer by facilitating the movement of the granular body in the packaging body 63 compared to the case where the packaging body 63 that does not stretch is used. This makes it easy to follow the body and improves the feeling of wearing the absorbent article 1.

  Moreover, in the part by which the granular layer 60 is arrange | positioned among the main-body parts 2 in the absorbent article 1, the granular body moves according to the change of the pressure from a wearer's body, and the absorbent core 31 follows the shape of the body. The shape changes.

  Thereby, in the part by which the granular layer 60 is arrange | positioned, a clearance gap does not arise between the absorbent article 11 and a wearer's body, and the leakage of the bodily fluid to the exterior of the absorbent article 11 can be prevented.

  When at least one of the skin contact surface side and the non-skin contact surface side of the package 63 is extensible, the pressure applied to the package 63 is released. Can return to its original shape (size). Therefore, even when the posture of the wearer is changed or the absorbent article 1 is once attached / detached and then used again, the granular material moves according to the change in pressure from the wearer's body each time, The shape of the absorption core 31 can be changed to follow the shape.

  At least one of the sheets including the core sheet 32 covering the top sheet 10, the back sheet 20, and the absorbent core 31 is configured to be extensible. Thereby, when the absorbent article 1 is deformed at the time of wearing, the extensible sheet is stretched, so that the absorbent article 1 can be prevented from being deformed to follow the body, and more absorbent articles. 1 can improve the feeling of wearing and prevent leakage of bodily fluids.

  Of the top sheet 10, the back sheet 20, and the core wrap 32, the portion overlapping the granular layer 60 in plan view is configured to be stretchable, so that the absorbent article 1 can be stretched in accordance with the movement of the underwear. Therefore, the main body of the absorbent article 1 can be extended in accordance with the movement of the granular material, and the absorbent article 1 can follow the movement of the body.

  The package 63 and the extendable sheet (the front sheet 10, the back sheet 20, and the core wrap 32) extend in at least one of the longitudinal direction L and the width direction W. In addition, the extending direction of the package 63 and the extendable sheet is configured to match. Thereby, the packaging body 63 and the sheet | seat which can be extended | stretched are extended in the same direction along the deformation | transformation direction of the absorbent article 1 bent (deformed) in the longitudinal direction L and the width direction W at the time of wear. That is, compared with the case where the extending directions are different, the absorbent article 1 can be more easily deformed to follow the body, and the wearing feeling of the absorbent article 1 can be improved and the body fluid can be prevented from leaking.

  The granular layer 60 is composed of a plurality of granular sections 61 divided by a package 63 in plan view. For example, when the granular layer 60 is not divided by the packaging body 63 (when the granular body is wrapped in one packaging body), the granular body is biased in a certain direction. In this case, depending on the part of the absorbent article 1, there may be a state in which there are few granular materials that move in accordance with a change in pressure during wearing. On the other hand, as in the absorbent article 1 of the present embodiment, by dividing the granular layer 60 by the packaging body 63, the bias in the direction of the granular body contained in the granular layer 60 is reduced, and the change in pressure in the wearing state is reduced. An appropriate amount of granules can be arranged in accordance with the portions having different sizes. That is, by disposing the granular section 61 over the entire absorbent article 1, that is, over a wide range, the absorbent article 1 is shaped according to the change in pressure in the entire absorbent article 1. Can be easily followed.

  By providing the granular layer 60 between the absorbent core 31 and the back sheet 20, the absorbent core is interposed via the top sheet 10 compared to the case where the granular layer 60 is provided between the top sheet 10 and the absorbent core 31. Since 31 absorbs bodily fluids, the absorbent capacity of the absorbent article 1 is not reduced.

  The absorber 30 includes a fiber assembly made of tow. When the absorbent body 30 includes a fiber assembly made of a tow that is more bulky, the body in the worn state and the absorbent article 1 can easily come into contact with each other, and the wearing feeling can be further improved.

  Since the granular material contained in the granular layer 60 is a resin foam bead particle having high fluidity, the granular layer 60 can easily move in the package 63 and the shape of the absorbent article 1 can easily follow the shape of the body. Can be transformed.

  The granular layer 60 is provided between the absorbent core 31 and the back sheet 20, includes fibers having water absorbency, and the fibers having absorption and the granular body included in the granular layer 60 are not joined to each other. Composed. Thereby, also in the granular layer 60, a bodily fluid can be absorbed and the absorption capacity of the absorbent article 1 can be improved.
