JP 2008-73449 A JP 2006-500196 A JP 2012-125354 A

  However, the absorbent article disclosed in Patent Document 1 can improve flexibility in both the product longitudinal direction and the product width direction by embossing as described above, but on the other hand, the product width direction There was a problem that the rigidity of the steel was insufficient and it became easy to bend.

  Moreover, the absorbent article currently disclosed by patent document 2 is only prescribed | regulated about the point to which flexibility changes with temperature changes, and is flexible in the complicated curve shape of a wearer's body in the product longitudinal direction. There is a problem that it may not be able to follow, or the rigidity in the product width direction may be insufficient to make it easy to bend.

  Furthermore, although the absorbent article currently disclosed by patent document 3 can improve a softness | flexibility equally in both the product longitudinal direction and the product width direction, it follows a complicated curve shape of a wearer's body flexibly. There was a problem that it was not possible.

  Therefore, the present invention has been made in view of the above-described problems, and is capable of flexibly following a complicated curved shape of the wearer's body in the product longitudinal direction while maintaining rigidity in the product width direction. The purpose is to provide goods.

  A first feature of the present invention has a product longitudinal direction and a product width direction orthogonal to each other, and includes a top sheet and an absorbent layer disposed on the underwear contact surface side of the top sheet. A plurality of recessed areas and a plurality of raised areas extending in the product width direction are provided on the top sheet, and a plurality of extending in the product width direction on the non-skin contact surface side. The gist of the present invention is that a shift prevention region is provided.

  As described above, according to the present invention, it is possible to provide an absorbent article that can flexibly follow a complicated curved shape of a wearer's body in the product longitudinal direction while maintaining rigidity in the product width direction. it can.

It is the top view seen from the skin contact surface side of the absorptive article concerning a 1st embodiment of the present invention. It is the top view seen from the non-skin contact surface side of the absorptive article concerning a 1st embodiment of the present invention. It is XX sectional drawing in FIG.1 and FIG.2. It is sectional drawing of the absorbent article which concerns on the 2nd Embodiment of this invention.

  With reference to FIG. 1 thru | or FIG. 3, the absorbent article 1 which concerns on the 1st Embodiment of this invention is demonstrated.

  In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones.

  Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings may be contained.

  FIG. 1 shows a plan view seen from the skin contact surface side of the absorbent article 1 according to this embodiment, and FIG. 2 shows the non-skin contact surface side (underwear application) of the absorbent article 1 according to this embodiment. FIG. 3 is a sectional view taken along line XX in FIGS. 1 and 2.

  In the present embodiment, a panty liner that is used by being worn in underwear will be described as an example of the absorbent article 1, but the present invention is not limited to such a case, and any sanitary napkin or the like can be used. It is applicable to absorbent articles.

  As shown in FIGS. 1 and 2, the absorbent article 1 according to this embodiment has a product longitudinal direction L and a product width direction that are orthogonal to each other.

  Moreover, the absorbent article 1 which concerns on this embodiment is equipped with the top sheet 2A and the absorption layer 2B arrange | positioned at the non-skin contact surface side D2 of the top sheet 2A, as shown in FIG. .

For example, the topsheet 2A is, PE (polyethylene) / PP (polypropylene) core-sheath structure or PE / PET (polyethylene terephthalate) Total with core-sheath structure or the like having a basis weight 15 to 80 g / m 2 (preferably, 18~60M 2 ), Or a span of 20 to 80 g / m 2 (preferably 25 to 60 g / m 2 ) using a rayon, cotton, PET, PE / PET core-sheath structure, or the like. may be constituted by a lace nonwoven fabric, the total basis weight 13~60g / m 2 (preferably, 15~45g / m 2) using a PP · PET long fibers may be constituted by a spun bond nonwoven fabric.

Further, the absorption layer 2B has a total basis weight 35~150g / m 2 (preferably, 40 to 100 g / m 2) may be constituted by a sheet made of air-laid nonwoven.

In addition, the back sheet 4 is arrange | positioned at the non-skin contact surface side D2 of the absorption layer 2B. For example, the back sheet may be constituted by a polyethylene film having a total basis weight of 18 to 50 g / m 2 (preferably 20 to 45 g / m 2 ). In addition, the absorbent article does not need to include a back sheet.

  Moreover, in the absorbent article 1 which concerns on this embodiment, as shown in FIG.1 and FIG.3, several recessed area | region 2 A1 extended in the product width direction W and several convex area | region 2 A2 are provided on the top sheet 2A. ing.

  Here, the plurality of recessed regions 2A1 may be formed intermittently or continuously along the product width direction W as shown in FIG.

  As described above, when the plurality of recessed regions 2A1 extending in the product width direction are formed, the wearer is visually presented with a horizontal stripe pattern (when the product longitudinal direction L is viewed vertically). Such striped patterns may remind the wearer of living things (such as crustaceans) and cause disgust.

The inventor of the present invention relates to the visual effect of the length L1 of the absorbent article 1 in the product longitudinal direction and the interval (pitch) L2 between the concave regions 2A1 (or convex regions 2A2) in the product longitudinal direction L. I found out. Specifically, the present inventor has found that the above-described visual effect appears strongly when the following relationship is established.
(Spacing (pitch) L2 (mm) between concave regions 2A1 (or convex regions 2A2) in product longitudinal direction L) ÷ (length L1 (mm) in the product longitudinal direction of absorbent article 1) × 100 = 3 .5-18%
In addition, when the above-mentioned relationship becomes larger than 18%, an appropriate softness | flexibility cannot be provided with respect to the absorbent article 1 which concerns on this invention, and it is unpreferable.

  Moreover, it is preferable that the space | interval (pitch) L2 of recessed part area | region 2 A1 (or convex part area | region 2 A2) in the product longitudinal direction L is 2-6 mm (preferably 2.5-5 mm).

  Here, when the above-mentioned distance (pitch) L2 is smaller than 2 mm, the distance (pitch) between the elements (recessed area 2A1 or raised area 2A2) that lowers the rigidity becomes narrower and appropriate for the absorbent article 1. It becomes impossible to impart a sufficient rigidity. On the other hand, if the above-mentioned interval (pitch) L2 is larger than 6 mm, the absorbent article 1 cannot flexibly conform to the shape of the body from the wearer's vulva to the buttocks.

  The interval (pitch) L2 in the present embodiment is the interval between the vertices of the convex portions. The interval (pitch) can be measured, for example, by the following method. First, the absorbent article is impregnated with liquid nitrogen to freeze the absorbent article. Next, after the absorbent article frozen by a razor is cut, the cut absorbent article is returned to room temperature and thawed. And the distance of the vertex of the adjacent convex part in a cut surface is measured with an electron microscope (Keyence VE7800).

  For example, in the process of manufacturing such an absorbent article 1, the concave region 2A1 and the convex region 2A2 may be formed on the top sheet 2A and the absorbent layer 2B by a number of groove-shaped shaped emboss patterns. In such a case, the top sheet 2A and part of the absorbent layer 2B are partially broken or reduced in weight on the bottom surface of the molded recessed area 2A1.

  Alternatively, a plurality of concave regions 2A1 and a plurality of convex regions 2A2 extending in the product width direction W may be formed on the top sheet 2A. In such a case, since the densities in the recessed area 2A1 and the raised area 2A2 are different, the rigidity of the recessed area 2A1 is smaller than the rigidity of the raised area 2A2.

  Specifically, the fiber arrangement in the fiber web is shaded by high-pressure hot air or steam on the streaky pattern mesh or cylinder, and the fiber amount of the portion corresponding to the convex region 2A2 corresponds to the concave region 2A1. The top sheet 2A may be formed by forming the sheet in a sheet shape after heat-sealing after forming the fiber to 1.3 to 20 times (preferably 2 to 10 times) the fiber amount of the portion. .

  In addition, in the range of a part of the absorbent article 1 (that is, a range that does not require rigidity in the product longitudinal direction of the absorbent article 1), the above-described recessed area 2A1 and raised area 2A2 are not arranged. May be.

  For example, in the range including the edge of the product longitudinal direction L of the absorbent article 1 and the range including the fold line of the absorbent article 1, the above-described concave region 2A1 and convex region 2A2 are not arranged. Also good.

Moreover, in the absorbent article 1 which concerns on this embodiment, as shown to FIG.2 and FIG.3, the several non-skin | contacting area | region 3 extended in the product width direction W is provided in the non-skin contact surface side D2 .

  Here, the slip prevention region 3 plays a role of fixing the absorbent article 1 to the wearer's underwear. In addition, in the state in which the absorbent article 1 is packaged, the shift preventing region 3 is covered with a separator or the like.

  For example, the length L3 in the product longitudinal direction L of each misalignment stop region 3 is preferably 1 to 6 mm (more preferably 1.5 to 5 mm). Moreover, it is preferable that the space | interval (pitch) L4 in the product longitudinal direction L of the slip prevention area | regions 3 is 1-8 mm (more preferably, 2-6 mm).

  According to the configuration as described above, by providing the concave region 2A1 and the convex region 2A2 extending in the product width direction W, the rigidity in the product width direction W increases and the rigidity in the product longitudinal direction L decreases.

  As described above, since the rigidity in the product longitudinal direction L is low, the wearer can feel the softness of the absorbent article when taking out the absorbent article 1 from the individual packaging, and the absorption. The followability to the wearer's body of the property article 1 can be improved.

  On the other hand, since the rigidity in the product width direction W is high as described above, even when the absorbent article 1 is sandwiched between the legs of the wearer, the occurrence of dripping can be prevented. .

  Further, by providing the slip stopper region 3 along the product width direction W, the slip stopper region 3 for fixing the absorbent article 1 to the wearer's underwear without hindering the reduction of the rigidity in the product longitudinal direction L. Can play its original role.

  Moreover, in the absorbent article 1 which concerns on this embodiment, as shown in FIG. 3, you may be comprised so that several recessed part area | region 2 A1 and several shift stop area | region 3 may not overlap at least partially (for example, , See region A in FIG. 3).

  According to this structure, there exists an effect that the reduction of the rigidity of the product longitudinal direction L is not inhibited more.

  Furthermore, in the absorbent article 1 according to the present embodiment, as shown in FIG. 3, the interval (pitch) L5 between the plurality of convex region 2A2 is different from the interval (pitch) L4 between the plurality of misalignment regions 3. It may be configured as follows.

  According to such a configuration, it is possible to provide a portion that does not hinder the reduction in rigidity in the product longitudinal direction L with a certain probability while avoiding a situation where the manufacturing process of the absorbent article 1 is complicated.

  Here, in the absorbent article 1 according to the present embodiment, the interval (pitch) L4 between the plurality of misalignment regions 3 is at least one of the edge regions in the product longitudinal direction L in the center region in the product longitudinal direction L. It may be configured to be longer.

  In addition, when the absorbent article 1 according to the present embodiment is equally divided into three in the product longitudinal direction L, the central region is a middle region in the product longitudinal direction L, and the edge region is the other region. .

  Generally, when a wearer walks or runs, a load is easily applied in the edge region in the product longitudinal direction L. Here, about the space | interval (pitch) L4 between the slip prevention area | regions 3, by making at least one of the edge region of the product longitudinal direction L shorter than the center area | region of the product longitudinal direction L, with respect to a wearer's intense movement Also, the adhesion between the underwear and the absorbent article 1 can be maintained.

  Moreover, in the absorbent article 1 which concerns on this embodiment, as shown in FIG. 3, the length L5 of the product longitudinal direction L of convex part area | region 2 A2 is longer than the length L3 of the product longitudinal direction L of the slip prevention area | region 3. You may be comprised so that it may become short.

  According to such a configuration, in the deformation state when the absorbent article 1 is mounted, the top sheet 2A is steeper than the misalignment region 3 between the top sheet 2A and the misalignment region 3 positioned on the skin contact surface side D1. It becomes a curve. As a result, since the length L5 in the product longitudinal direction L of the convex region 2A2 is shorter than the length L3 in the product longitudinal direction L of the shift preventing region 3, smooth deformation can be performed.

  Further, the interval (pitch) L4 between the plurality of misalignment regions 3 may be configured to be an integral multiple of the interval (pitch) L5 between the plurality of convex regions 2A2.

  According to such a configuration, the number of the plurality of misalignment regions 3 can be reduced, and a portion that does not hinder the reduction in rigidity in the product longitudinal direction L can be efficiently provided.

  The absorbent article of this Embodiment can be manufactured with the following method, for example. The manufacturing method of an absorbent article performs a top sheet production | generation process first. Specifically, a convex region and a concave region are formed on the top sheet. Specifically, after forming the fiber web, a light and shade is formed on the fiber arrangement by high-pressure hot air or steam on a streaky pattern mesh or cylinder. After forming so that the convex region is 1.3 to 20 times, preferably 2 to 10 times the fiber amount, it is formed into a sheet by heat-sealing.

  The top sheet and the absorbent layer are joined. Subsequently, the adhesive which comprises the slip prevention area | region 3 is apply | coated on the non-skin contact surface of an absorbent layer in the absorbent article which does not have a back sheet in the absorbent article which has a back sheet. And a back sheet | seat, a top sheet | seat, and an absorption layer are joined and integrated. The absorbent article which concerns on this Embodiment can be manufactured according to said process.

  Next, an absorbent article 1A according to a second embodiment will be described with reference to FIG. In the description of the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 4 is a cross-sectional view of an absorbent article 1A according to the second embodiment. The sectional view is a sectional view based on the XX section of the first embodiment. Absorbent article 1A according to the second embodiment includes top sheet 2A, absorbent layer 2B disposed on non-skin contact surface side D2 of top sheet 2A, and non-skin contact surface side D2 of absorbent layer 2B. The liquid-impermeable back sheet 4 is disposed, and the nonwoven fabric sheet 5 is disposed on the non-skin contact surface side D <b> 2 of the back sheet 4. The misalignment stop region 3 is provided on the non-skin contact surface side of the nonwoven fabric sheet 5.

It is preferable that the thickness of the nonwoven fabric sheet 5 is 0.08 mm or more and 0.25 mm or less. The basis weight of the nonwoven fabric sheet 5 is preferably 20 g / m 2 or less. Moreover, it is preferable that the water pressure resistance of a nonwoven fabric sheet is 30 mbar or less. Examples of the nonwoven fabric sheet 5 include an SMS nonwoven fabric, a spunbond nonwoven fabric, and a spunlace nonwoven fabric.

  The thickness of the nonwoven fabric sheet 5 can be measured by the following method, for example. First, the absorbent article is impregnated with liquid nitrogen to freeze the absorbent article. Next, after the absorbent article frozen by a razor is cut, the cut absorbent article is returned to room temperature and thawed. And the thickness of the nonwoven fabric sheet 5 in a cut surface is measured with an electron microscope (Keyence Corporation VE7800).

  A joining region (not shown) is provided between the back sheet 4 and the nonwoven fabric sheet 5. The joining region is a region where a bonding adhesive that joins the back sheet 4 and the nonwoven fabric sheet 5 is disposed. The bonding adhesive is applied to the skin contact surface side D1 of the nonwoven fabric sheet 5 or the non-skin contact surface side D2 of the back sheet 4.

  The slip prevention adhesive provided in the slip prevention region 3 penetrates the nonwoven fabric sheet 5 in the thickness direction. The slip prevention adhesive is impregnated into the nonwoven fabric sheet 5 and reaches the skin contact surface side D1 of the nonwoven fabric sheet 5. Therefore, in the region where the joining region and the displacement prevention region overlap in the thickness direction, the bonding adhesive and the displacement prevention adhesive are in contact with each other, and the bonding adhesive and the displacement prevention adhesive are bonded. In this embodiment, “the anti-slip adhesive penetrates through the non-woven sheet in the thickness direction” means that the anti-slip adhesive impregnates the non-woven sheet and one side of the non-woven sheet (for example, non-skin That is, the adhesive disposed on the contact surface reaches the other surface (skin contact surface).

  The bonding adhesive and the anti-displacement adhesive have different properties. Specifically, the bonding adhesive is configured to bond the back sheet 4 and the nonwoven fabric sheet 5 and maintain the bonded state. On the other hand, the slip prevention adhesive is configured to removably bond the absorbent article to the undergarment. As the bonding adhesive and the anti-slipping adhesive, an adhesive that is usually used in an absorbent article can be used, and examples thereof include a hot melt adhesive.

  1 A of absorbent articles which concern on 2nd Embodiment have the nonwoven fabric sheet 5 arrange | positioned at the non-skin contact surface side D2 of the back sheet 4. FIG. By having the non-woven fabric sheet 5, the flexibility of the absorbent article is increased, and it becomes easier to deform along the complex curved shape of the body.

  Moreover, in the structure which joins the back sheet 4 and the nonwoven fabric sheet 5, compared with the structure which joins the absorption layer 2B and the back sheet 4, the joining strength of the back sheet 4 and the nonwoven fabric sheet 5 tends to become low. . Therefore, if the absorbent article is flexibly deformed along the body, the back sheet 4 and the nonwoven fabric sheet 5 may be peeled off. However, when the bonding adhesive and the adhesive in the misalignment region are in contact with each other, the bonding adhesive and the adhesive in the misalignment region are bonded to increase the strength of the bonding adhesive. Therefore, even when the absorbent article is deformed flexibly along the body, it is possible to suppress the back sheet 4 and the nonwoven fabric sheet 5 from being separated.

  The thickness of the nonwoven fabric sheet 5 is 0.08 mm or more and 0.25 mm or less. For example, when the thickness of the non-woven fabric sheet 5 is less than 0.08 mm, the non-slip adhesive is excessively impregnated in the non-woven fabric sheet 5 and is disposed on the non-skin contact surface side of the non-woven fabric sheet 5. The amount of the agent may be reduced. If the amount of the anti-slip adhesive disposed on the non-skin contact surface side of the nonwoven fabric sheet 5 is reduced, there is a possibility that sufficient adhesive force to adhere the absorbent article to the undergarment cannot be secured. Moreover, when the thickness of the nonwoven fabric sheet 5 is larger than 0.25 mm, the slip prevention adhesive cannot penetrate the nonwoven fabric sheet 5, and the slip prevention adhesive and the bonding adhesive may not be joined.

  The joining region provided with the bonding adhesive extends in the product width direction. When the joining region and the misalignment prevention region extend in the same direction, the joining region and the misalignment prevention region are thicker than a configuration in which the joining region and the misalignment prevention region extend in different directions (for example, orthogonal directions). It becomes easy to overlap in the direction. The bond strength of the bonding adhesive can be increased by the bonding of the bonding adhesive and the anti-displacement adhesive.

  The viscosity of the bonding adhesive is higher than the viscosity of the slip prevention adhesive. Since the bonding adhesive is relatively high in viscosity, it is difficult to impregnate the nonwoven fabric sheet 5. Therefore, the bonding adhesive remains between the nonwoven fabric sheet 5 and the backsheet 4 and can maintain the bonding between the nonwoven fabric sheet 5 and the backsheet 4. On the other hand, since the anti-slipping adhesive has a relatively low viscosity, it is easy to impregnate the nonwoven fabric sheet 5. Therefore, the slip prevention adhesive can penetrate the nonwoven fabric sheet 5 and can be bonded to the bonding adhesive.

The viscosity in the present embodiment is a viscosity measured by the following method. First, a sample chamber (internal volume: 20 ml) is placed in a thermo container (37-260 ° C.) and fixed. The temperature controller is then set to the measured temperature. After the temperature rise, the spindle attached to the Brookfield viscometer (250-500000 mPa · S) is set at a predetermined position, and the measurement is performed after adjusting the sample temperature. The viscosity is calculated by the following formula.
Viscosity (mPa · S) = viscosity indicator value × multiplier The multiplier is determined by the rotational speed of the viscometer. The relationship between the rotational speed and the multiplier is shown in Table 1 below.

  Moreover, the pressing part which compressed the back sheet and the nonwoven fabric sheet at least in the thickness direction may be formed in the periphery of the absorbent article. The pressing part may be formed on the entire periphery of the absorbent article, or may be formed on the periphery of the absorbent article. The joining area | region may be arrange | positioned at the pressing part located in the periphery of an absorbent article.

  The bonding adhesive may be provided in the pressing part. By providing the squeezed part, the slip prevention adhesive is more easily impregnated in the thickness direction. Since the bonding adhesive is provided in the pressing portion, the anti-displacement adhesive and the bonding adhesive are more easily bonded, and the bonding strength of the bonding adhesive can be increased. On the other hand, since the slip prevention adhesive is impregnated in the nonwoven fabric sheet 5, the amount disposed on the non-skin contact surface side of the nonwoven fabric sheet 5 is reduced. Therefore, the adhesive strength of the anti-slipping adhesive is weakened, and the absorbent article can be easily removed from the underwear, and even if the anti-slipping adhesive adheres to the skin unintentionally, Sticking can be suppressed.

  Although the present invention has been described in detail using the above-described embodiments, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modified and changed modes without departing from the spirit and scope of the present invention defined by the description of the scope of claims. Therefore, the description of the present specification is for illustrative purposes and does not have any limiting meaning to the present invention.
