Description

  The present invention relates to an absorbent article used for absorbing body fluids, such as sanitary napkins and incontinence pads.

  The present applicant has previously proposed an absorbent article comprising a leak-proof groove having a predetermined shape formed on the surface layer side of the absorbent layer, and a leak-proof wall standing from the vicinity of each of the left and right side edges of the absorbent layer. (See Patent Document 1). The leak-proof wall has a base wall part, and an inwardly extending part and an outwardly extending part that protrude from the upper part of the base wall part to the inside and the outside of the absorbent article, respectively. Each of the inwardly extending part and the outwardly extending part is provided with an elastic member along its length direction. The inward projecting portion is located above the absorption layer and outside the leak-proof groove. The leak-proof groove has a closed shape close to an elliptical shape having a major axis in the length direction of the absorbent article. This absorbent article has high fit, and liquid leakage is effectively prevented. In addition, liquid leakage is effectively prevented even when the leak-proof wall is crushed by the mounting pressure.

  In addition to the absorbent article, there is known an absorbent article in which a leak-proof groove having a closed shape is formed around the blood drainage site of the wearer regarding the shape of the leak-proof groove (see Patent Document 2). . This leak-proof groove has a bulging embossed portion that bulges outward in the width direction on both sides of the blood drainage site of the wearer. A gather cuff extending in the longitudinal direction of the absorbent article is provided outside the bulging embossed portion. When the gather cuff contracts, the absorbing element contracts in the longitudinal direction by the contraction force. By this contraction, the bulging embossed portion swells toward the blood drainage site of the wearer. That is, in this absorbent article, when the absorbent element contracts in the longitudinal direction, a middle and high part that bulges into the absorbent element is formed. However, this absorbent article does not include the leak-proof wall having the above-described inwardly extending portion and outwardly protruding portion.

  With regard to the formation of the middle and high parts, while wearing the absorbent article, it uses the compressive force applied to the absorbent article from the lateral direction to lift the vertically long central area toward the wearer's skin and adhere closely to the wearer's body There has been proposed an absorbent article (see Patent Document 3). Although this absorbent article has a leak-proof groove having a closed shape, the above-mentioned bulging embossed portions are formed on both sides of the blood drainage site of the wearer. Not.

  An object of the present invention is to provide an absorbent article that can effectively utilize an absorbing surface positioned between leak-proof walls and can stably raise the absorbing surface on the skin side of the wearer.

The present invention relates to an absorbent article having leakage preventing grooves located on the left and right side portions on the surface layer side and extending in the longitudinal direction, and leakage preventing walls located on the outer sides of the leakage preventing grooves and extending in the longitudinal direction, respectively. In
The leak-proof wall includes a base wall portion and a skin contact surface portion projecting horizontally from the upper end of the base wall portion, and an elastic member extending in the longitudinal direction of the leak-proof wall is provided on the skin contact surface portion. It is arranged in an extended state,
Each leak-proof groove achieves the above-described object by providing an absorbent article in which a portion facing the excretion part of the wearer is curved convexly outward in the width direction of the absorbent article. is there.

  According to the absorbent article of the present invention, the leak-proof groove is such that the portion facing the excretion part of the wearer is convexly curved outward in the width direction of the absorbent article. As a starting point of bending, the absorbent article is easily pushed up to the body side. As a result, the leak-proof wall is easily opened outward, and the absorption surface is not easily covered by the leak-proof wall. Therefore, it is possible to effectively use the absorption surface, and the leakage prevention effect is enhanced. In addition, since the absorbent article is easily pushed up to the body side with the leakage prevention groove as a starting point of bending, the absorbent body positioned between the leakage prevention grooves is easily and stably swelled. Adheres closely to the skin, further enhancing the leak-proof effect.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a plan view of a sanitary napkin as an embodiment of the absorbent article of the present invention as seen from the top sheet side, and FIG. 2 shows a cross-sectional view taken along the line II-II in FIG. It is shown.

  As shown in FIGS. 1 and 2, the sanitary napkin 1 of the present embodiment has a vertically long shape, a top sheet 2 as a liquid-permeable surface layer, and a back as a liquid-impermeable back layer. The sheet 3 and the absorbent body 4 as a liquid retaining absorbent layer interposed between the top sheet 2 and the back sheet 3 are provided. A pair of leak-proof walls 5 and 5 are arranged along the longitudinal direction on the left and right side portions on the top sheet side of the napkin 1. The leak-proof wall 5 stands from the vicinity of the left and right side edges of the absorber 4.

  The napkin 1 includes an excretion part facing part A that is a part facing the excretion part of the wearer when worn, and a front part B and a rear part that are adjacent to the excretion part facing part A and located in front and rear of the napkin 1, respectively. It is divided into part C.

  The top sheet 2 covers the entire area of the upper surface of the absorbent body 4 and extends from the side edge of the absorbent body 4 and is wound on the back sheet side. The top sheet 2 can be made of the same material as a conventionally known one, and for example, a hydrophilic nonwoven fabric or an apertured film is used. The back sheet 3 is composed of, for example, a liquid impermeable film sheet (preferably a water vapor permeable and liquid impermeable film sheet). The absorbent body 4 is configured by, for example, a mixture of fluff pulp and superabsorbent polymer particles wrapped in tissue paper.

  The back sheet 3 extends outward from the side edge of the absorbent body 4 and forms a pair of wings 6 at the position of the excretory part facing part A of the napkin 1. Although not shown, an adhesive layer for fixing the napkin 1 to the clothing is formed on the clothing facing surfaces of the back sheet 3 and the wing 6. The pressure-sensitive adhesive layer is protected by a release paper (not shown).

  The top sheet 2 and the back sheet 3 respectively extend from the front and rear ends of the absorber 4, and the extended top sheet 2 and the back sheet 3 are bonded and fixed to each other to form an end seal portion 7.

  The leak-proof walls 5 disposed on the left and right sides of the napkin 1 are formed by processing a single belt-like sheet into a sleeve shape and a T-shape. The leak-proof wall 5 includes a base wall portion 5a. The base wall portion 5 a has a fixed end and a free upper end, and the fixed end stands on the back sheet at a position slightly outward from the side edge of the absorber 4.

  The leak-proof wall 5 further includes a skin contact surface portion 5b. The skin contact surface portion 5b is a planar portion projecting in the horizontal direction from the upper end of the base wall portion 5a. The skin contact surface portion 5b protrudes inward and outward in the width direction of the napkin 1 with the same amount of protrusion. The overhang of the skin contact surface portion 5 b extends over the entire length direction of the napkin 1. The skin contact surface portion 5b is a flat surface substantially parallel to the skin contact surface of the napkin 1, particularly at the position of the excretory portion facing portion A. The skin contact surface portion 5b is configured such that the upper surface of the skin contact surface portion 5b contacts the wearer's skin when the napkin 1 is attached.

  A plurality of elastic members 5c extending in the longitudinal direction of the leak-proof wall 5 are disposed on the skin contact surface portion 5b. The constituent material of the elastic member 5c is not particularly limited as long as it is normally used for absorbent articles. For example, foams of polyolefins and polyurethanes and natural rubber are preferably used. The shape of the elastic member 5c can be a thread, a band, a film, or the like. In this embodiment, a thread-like elastic member is used. The elastic member 5 c is disposed at least in the excretion part facing part A of the napkin 1. The elastic member 5c is fixed in an expanded state in the sheet forming the leak-proof wall 5. As this fixing means, a heat seal or a hot melt adhesive is used. The expansion ratio of each elastic member 5c is substantially the same.

In the natural state of the napkin 1, the leak-proof wall 5 stands up reliably because the elastic member 5c contracts. According to the leak-proof wall 5 having such a configuration, the surface sealing effect that the upper surface of the skin contact surface portion 5b is in close contact with the wearer's thigh elastically and on the surface appears. As a result, it becomes difficult to be affected by misalignment caused by the wearer's movement, and liquid leakage is effectively prevented. Further, even in a situation where the leak-proof wall 5 is likely to be pushed inward due to the wearer's movement, the leak-proof wall 5 is inclined outward by the tension of the elastic member 5c arranged on the outer side in the width direction. The force works and the leak-proof wall 5 is effectively prevented from being pushed down inward. As a result, the degree of adhesion of the skin contact surface portion 5b to the thigh is maintained high. In particular, by disposing the elastic member 5c in the vicinity of the left and right free ends of the skin contact surface portion 5b, the horizontal contact of the skin contact surface portion 5b is further stabilized, and the aforementioned surface sealing effect is further improved. .

  The leak-proof wall 5 is fixed to the top sheet 2 at the positions of the front part B and the rear part C. The skin contact surface portion 5b is not fixed to the top sheet 2 at the position of the excretory portion facing portion A. As a result, the leak-proof wall 5 is more likely to stand at the position of the excretory part facing part A, and the back sheet side of the napkin 1 is curved in a convex shape so that the whole napkin is shaped along the wearer's body shape. As a result, the upper surface of the skin contact surface portion 5b is more stably adhered to the wearer's thigh, and the surface sealing effect is further exhibited. In particular, when the wing 6 is provided outside the standing position of the leak-proof wall 5 as in this embodiment, the leak-proof wall 5 is caused by the folding of the wing 6 when the napkin 1 is attached. A force that stabilizes the base end position outwardly acts, and the liquid receiving area on the skin facing surface side of the napkin 1 is also widened.

  Due to the fact that the force that stabilizes the base end position of the leak-proof wall 5 outwards works, and the longitudinal front and rear end portions of the skin contact surface portion 5b are fixed at the longitudinal front and rear end portions of the napkin. As a result, the skin contact surface portion 5b of the leak-proof wall 5 is hardly affected by the movement of the wearer's thigh, and the surface shape is stably expressed. Furthermore, the liquid receiving area on the skin facing surface side is further widened. As the length of the napkin increases, the distance between the positions at which the longitudinal front and rear ends of the skin contact surface portion 5b are fixed increases, so that the influence of the movement of the wearer's thigh is reduced. As a result, a better effect can be obtained.

  On the top sheet side of the napkin 1, leakage preventing grooves 8, 8 extending in the longitudinal direction of the napkin 1 are formed on both sides thereof. Each leak-proof groove 8 is formed by consolidating and integrating the top sheet 2 and the absorber 4 by pressing means such as embossing from the top sheet side. Each leakage prevention wall 5 described above is located outside each leakage prevention groove 8. Each leak-proof groove 8 has a substantially symmetric shape with respect to the vertical center line of the napkin 1. The leakage prevention grooves 8 are connected to each other at their front and rear ends, thereby forming a closed shape as a whole.

  Each leak-proof groove 8 has a portion located in the excretory portion facing portion A curved in a convex shape outward in the width direction of the napkin 1 (hereinafter, this portion is referred to as a central curved groove 8a). The front and back of the central curved groove 8a extend in the longitudinal direction of the napkin to form a front groove 8b and a rear groove 8c, respectively. The central curved groove 8a and the leak-proof groove 8 including the front groove 8b and the rear groove 8c extending from the front and rear of the central curved groove 8a extend over almost the entire length of the napkin 1. The front groove 8b and the rear groove 8c are curved in a convex shape toward the outer side in the width direction of the napkin 1, similarly to the central curved groove 8a. As a result, each leak-proof groove 8 has a constricted portion 9a at the position of the connecting portion between the central curved groove 8a and the front groove 8b. In addition, a constricted portion 9b is provided at the position of the connecting portion between the central curved groove 8a and the rear groove 8c.

  As shown in FIG. 2, when the napkin 1 is viewed in the width direction, there is a difference in the thickness of the absorbent body 4 between the leak-proof grooves 8 and 8 and the outside of the leak-proof groove 8. As apparent from FIG. 2, the thickness is larger in the region surrounded by the closed leakage prevention groove 8, that is, between the leakage prevention grooves 8, 8 than the outside of the leakage prevention groove 8. In the present embodiment, the constituent material of the absorber 4 is the same between the leak-proof grooves 8 and 8 and the outside of the leak-proof groove 8, so the difference in the thickness of the absorber 4 is the basis weight of the absorber 4. This corresponds to the difference. That is, in the napkin 1, there is a difference in basis weight between the absorbent body 4 positioned between the leak-proof grooves 8 and 8 and the absorbent body 4 positioned outside the leak-proof groove 8. The absorbent body 4 located in the upper part has a higher basis weight than the absorbent body 4 located outside the leak-proof groove 8. As a result, in the napkin 1, the area surrounded by the leak-proof groove 8 has a shape that rises more than the peripheral area located outside the leak-proof groove 8.

According to the napkin 1 of the present embodiment having the above-described configuration, when the compressive force from the lateral direction is applied to the napkin 1 due to the movement of the wearer in the mounted state of the napkin 1, the leak-proof walls 5 are mutually connected. It becomes difficult to approach. That is, the surface on the top sheet side that is the absorption surface of the napkin 1 is difficult to be covered with each leak-proof wall 5, in particular, each skin contact surface portion 5b. As a result, the absorption surface can be used effectively and the leakage prevention effect is enhanced. This is because the leak-proof groove 8 located in the excretory part facing part A of the napkin 1 forms a central curved groove 8a that is curved convexly outward in the width direction of the napkin 1. . Specifically, when a compressive force from the lateral direction is applied to the napkin 1, the compressive force is dispersed in the longitudinal direction of the groove by the arch shape of the central curved groove 8a, and is difficult to be transmitted to the inside of the absorber 4. As a result, as schematically shown in FIG. 3, the napkin 1 is likely to be bent at the central curved groove 8 a as the starting point of the bending. In particular, when the constricted portions 9a and 9b are formed before and after the central curved groove 8a, the compressive force applied to the napkin 1 from the lateral direction is more effectively transmitted to the longitudinal direction of the central curved groove 8a. The mountain break of the napkin 1 with the curved groove 8a as the starting point of the bending occurs more reliably.

  On the other hand, in the case where the conventional napkin 1 ′ shown in FIG. 4, that is, the leak-proof groove 8 ′ positioned in the excretory part facing part A ′ is not curved convexly outward in the width direction, When the compressive force from the direction is applied to the napkin 1 ′, the napkin 1 ′ is likely to be bent at the leakage preventing groove 8 ′ as a starting point of bending as schematically shown in FIG. When the valley fold is remarkable, as shown schematically in FIG. 5 (b), the skin contact surface portion 5b ′ of the leak-proof wall 5 ′ is distorted, and the surface sealing effect by the skin contact surface portion 5b ′. Will fall. The reason why the phenomenon shown in FIGS. 5A and 5B occurs is that the compressive force applied to the napkin 1 ′ from the lateral direction cannot be stopped by the leak-proof groove 8 ′, and the compressive force is absorbed. This is because it is transmitted to the inside of the body 4. This phenomenon is particularly remarkable when the leak-proof groove 8 ′ located in the excretory part facing part A ′ is narrowed inward in the width direction.

  As described above, the feature of the napkin 1 according to the present embodiment is that the napkin having the leak-proof wall 5 including the skin contact surface portion 5b that projects in a planar shape in the horizontal direction from the tip of the base wall portion 5a is the excretory portion facing portion. The leak-proof groove 8 located at A is in a point curved outwardly in the width direction of the napkin 1. According to the napkin 1 of this embodiment, the problems peculiar to the case of using the leak-proof wall 5 are solved without impairing the various advantages described above with respect to the leak-proof wall 5 provided with the skin contact surface portion 5b. The Therefore, even if the napkin provided with the leak-proof wall not having the skin contact surface portion 5b is formed with the leak-proof groove 8 curved in a convex shape toward the outer side in the width direction of the napkin 1, that is, the central curved groove 8a. The remarkable effect which is show | played in the napkin 1 of this embodiment is not show | played.

  In the napkin 1 of the present embodiment, as shown in FIG. 3, the napkin 1 is easy to be bent with the central curved groove 8a as a starting point of bending, so that the absorption surface, that is, the surface on the top sheet side is stably raised. It comes in close contact with the wearer's body. As a result, the fitting property of the napkin 1 is enhanced, thereby further improving the leakage prevention effect. In particular, since the raised portion of the absorbent body 4 is surrounded by the leak-proof groove 8 having a closed shape, the stability of the surface shape of the portion is further enhanced.

As a result of the examination by the present inventors, it is effective to increase the basis weight of the absorbent body 4 positioned between the leak-proof grooves 8 and 8 in order to raise the absorption surface more stably. As described above, the absorbent body 4 positioned between the leak-proof grooves 8 and 8 has a high basis weight, but the basis weight is 300 to 1500 / m 2 , particularly 500 to 1200 g / m 2 . Then, it becomes possible to raise the absorption surface even more stably. The basis weight within this range is also advantageous from the viewpoint that the napkin 1 is easily pushed up to the body side with the central curved groove 8a as a starting point of bending by the pressure applied from the side of the napkin 1. In addition, in the range of 300-900 g / m < 2 > among the ranges of the said basic weight, the effect used as the starting point of bending is main, and the effect used as the starting point of bending in the range of 900-1500 g / m < 2 >. In addition, there is also an effect that the middle and high parts are slightly deformed into a drum shape and are easily raised.

The basis weight of the absorbent body 4 positioned between the leak-proof grooves 8 and 8 is as described above, while the basis weight of the absorbent body 4 positioned outside the leak-proof groove 8 is 100 to 400 g / m 2 , in particular. It is preferable that it is 150-300 g / m < 2 > from a viewpoint which raises an absorption surface more stably, and a viewpoint from which the napkin 1 can be easily pushed up to the body side from the center curved groove 8a as a starting point of bending.

  From the same viewpoint, in the absorber 4, the region having the high basis weight is the shape of the leak-proof groove 8 in which the outline of the region forms a closed shape when the absorber 4 is viewed in plan. It is preferable to match. In order to configure the absorber 4 in this way, for example, the absorber 4 has a two-layer configuration of a lower layer absorber and an upper layer absorber laminated thereon, and follows the outline of the upper layer absorber in plan view. Thus, the leakage prevention groove 8 may be formed.

Further, from the same viewpoint, as shown in FIG. 6, the central curved groove 8a is formed between the length L of the line segment connecting the front and rear constricted portions 9a and 9b , and the apex of the central curved groove 8a. It is preferable that L / D which is a ratio with the distance D is 2.5 to 20, particularly 5 to 15. With respect to the values of L and D themselves, L is preferably 50 to 100 mm, particularly 60 to 80 mm, and D is preferably 5 to 20 mm, particularly 5 to 10 mm.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, in the above-described embodiment, the amount of the skin contact surface portion 5b in the leak-proof wall 5 that protrudes in the horizontal direction is approximately the same between the inner side and the outer side in the width direction. The amount of overhang may be different between the outer side and the outer side.

  As shown in FIG. 2, the fixed state of the fixed end of the base wall portion 5 a in the leak-proof wall 5 is fixed by extending both sides of the sheet constituting the leak-proof wall 5 outward from the lower part of the absorber 4. It is good also as an aspect shown to Fig.7 (a) and FIG.7 (b). In Fig.7 (a), the both sides of the sheet | seat which comprises the leak-proof wall 5 are extended toward the side edge part of the napkin from the fixed end of the base wall part 5a. In FIG.7 (b), while the one side part of the sheet | seat which comprises the leak-proof wall 5 is extended toward the absorber 4 from the fixed end of the base wall part 5a, the other side part of this sheet | seat However, it extends toward the side edge of the napkin from the fixed end of the base wall 5a.

  In the above-described embodiment, the front and rear ends of each leakage prevention groove 8 are connected to each other. Alternatively, either the front end or the rear end may not be connected, or Both front and rear ends may not be connected.
