Description

Absorbent article

The present invention relates to an absorbent article.

BACKGROUND ART [0002] As an absorbent article such as a sanitary napkin, there is known an absorbent article having a pair of pressing grooves for bonding a top sheet to an absorbent body. The compression grooves are formed in order to improve the absorbing performance and the deformation performance. For example, Patent Document 1 discloses an absorbent article having an absorbent element between a liquid-pervious top sheet and a liquid-impervious back sheet. This absorbent article has a pair of first embossments formed on both sides of the longitudinal center line of the absorbent element in a substantially symmetrical manner with respect to the center line and in a convex shape toward the longitudinal center line side, A pair of second embossments formed on both sides of the center line in a substantially symmetrical manner and formed in a convex shape toward the outside in the width direction of the absorbing element at the center line side in the longitudinal direction. And the second embossment with respect to the center line is disposed outside the first embossment.

Patent Document 1: JP-A-2012-120792

A pair of compression grooves such as the emboss of Patent Document 1 are formed such that their positions and shapes are line-symmetrical with respect to the center line in the longitudinal direction of the absorbent body (absorbent element) from the standpoint of improvement of absorption performance and the like. Regardless of whether the consumer is conscious or not, the position (including symmetry) of the pair of compression grooves is confirmed mainly by any of the following methods (1) to (3) at the time of mounting. That is, (1) the distance between one end edge of the absorber and one of the pressing grooves opposite to the other end edge in the width direction, and the distance between the other end edge of the absorber and the other pressing groove facing the other end edge are compared . (2) The center position between the pair of compression grooves in the width direction is compared with the center position of the absorber. (3) The distance between the center position between the pair of compression grooves and the distance between one end edge of the absorbent body and the center position between the pair of compression grooves and the distance between the other end edge of the absorbent body in the width direction do.

At this time, for reasons of manufacturing, the position in the width direction of the compression groove in the product may be shifted from the position in the width direction of the compression groove in design. In this case, the consumer recognizes the positional shift in the width direction of the compression grooves mainly by any one of the following (a) to (c) in correspondence with the above (1) to (3). That is, (a) a difference arises between the two distances of (1). (b) a deviation occurs between the two center positions of (2). (c) a difference arises between the two distances of (3). As a result, the consumer recognizes that the position in the width direction of the compression groove in the absorbent article is distorted. Therefore, there is no problem in the absorbing performance, and even if the product is good, the consumer may perceive the absorbent article as a defective product because the position of the pressing groove is different from the original.

Nevertheless, eliminating the pair of compression grooves so as not to be recognized as defective products, that is, to make it difficult to recognize the positional displacement, is liable to cause outward leakage of the excreted liquid and disordered deformation, Which is undesirable.

It is an object of the present invention to provide an absorbent article which can make it difficult for a consumer to recognize a positional deviation even if the position of the squeeze groove is distorted in the width direction without causing deterioration of the absorbing performance.

The absorbent article of the present invention is as follows.

(1) An absorbent article having a longitudinal direction, a width direction, and a thickness direction, and having a top sheet, a back sheet, and an absorbent body disposed between the top sheet and the back sheet, Wherein the absorbent article is provided with a pair of pressing grooves in a region where the topsheet and the absorbent article are overlapped in the thickness direction at a position away from the pair of pressing grooves toward one side in the longitudinal direction, Wherein the pair of compression grooves, the first compression portion, and the second compression portion join the topsheet and the absorbent body, and the first compression portion has a first compressed portion and a second compressed portion lined up, Wherein the center of gravity of the first pattern is located at one side with respect to the longitudinal centerline, Wherein the second pattern has a center of gravity located on the other side with respect to the longitudinal center line, and the center of gravity of the second pattern is located on the other side with respect to the longitudinal centerline, Wherein the pressing portion has at least one of a position and a slope relative to the longitudinal centerline.

In this absorbent article, at least one of a position, a slope, and a size relative to one side and the other side of the longitudinal centerline is different from the first compressed portion having the first pattern and the second compressed portion having the second pattern different from the first compressed portion Respectively.

The first squeezing portion and the second squeezing portion are not line-symmetric with respect to the longitudinal center line in the shape of the pattern, the relative position, or the inclination, and are formed so as to extend from one end edge in the width direction of the absorbent body to the other end edge, Distance is not equidistant. Therefore, the consumer who has viewed these first and second pressing portions does not become aware of the relationship between the longitudinal center line and the width direction of the absorbent body, and the relationship between the one end edge and the other end edge in the width direction. Therefore, even if the distance between one end edge of the absorber and the first squeezed portion and the distance between the other end edge of the absorber and the second squeezed portion are not the same in the width direction, it is difficult to recognize that the position is deviated. Even if the position of the center between the first pressing portion and the second pressing portion and the position of the center position of the absorbent body are different, it is difficult to recognize that the positional deviation is caused. Even if the distance between the center position between the first pressing portion and the second pressing portion and the distance between one end edge of the absorber and the distance between the center position between the first pressing portion and the second pressing portion and the distance between the other end edge of the absorber are not equal It is hardly recognized as a positional deviation.

The visual effects of the first and second pressing portions are such that they are applied to the pair of pressing grooves adjacent to the first pressing portion and the second pressing portion in the longitudinal direction, Even if the positional deviation occurs, it becomes difficult for the consumer to recognize the positional deviation. That is, it is possible to make it difficult for the consumer to recognize the positional shift in the width direction in the pair of compression grooves.

At this time, since the first pressing portion and the second pressing portion are joined to the absorbent body by the surface sheet and extend from the surface of the topsheet to the inside of the absorbent body, the excreted liquid can be guided to the inside of the absorbent body, It is possible to suppress the movement to the outside of the direction. On the other hand, since the pair of compression grooves are not removed and the topsheet and the absorbent body are joined to each other and extend from the surface of the topsheet to the inside of the absorbent body, the excreted liquid can be guided to the inside of the absorbent body, Can be suppressed. The absorption performance of the absorbent article can be maintained and improved by the synergistic effect of the first and second squeezing portions and the pair of squeezing grooves.

Therefore, in the present absorbent article, it is possible to make it difficult for the consumer to think that the absorbent article is defective while maintaining the absorbing performance, so that the feeling that the absorbent article is good can be avoided.

The absorbent article of the present invention is characterized in that (2) the size in the width direction of each of the first pressing portion and the second pressing portion is not less than 1/10 and not more than 3/4 of the size of the absorbent body in the width direction 1).

In the absorbent article according to the present invention, since the size of each of the pressed portions in the width direction is in the predetermined range, it is possible for the consumer not to be conscious of the relationship between the respective pressing portions and the longitudinal center line or the end edge of the absorbent body. This makes it difficult to recognize the positional displacement of the first and second pressing portions. Therefore, it is possible to make it difficult for the consumer to recognize the positional displacement of the pair of the pressing grooves in the width direction by the visual effect. However, if the size of the crimping portion in the width direction is smaller than the above-mentioned predetermined range, it can not affect the consciousness of the consumer, and if the crimping portion is large, the positional deviation of the crimping portion becomes conspicuous.

(3) The size of one of the first press portion and the second press portion in the width direction is not less than 25% and not more than 400% of the size of the other width direction 1) or (2).

In this absorbent article, since the relationship in the width direction between the first press portion and the second press portion has the above-mentioned predetermined range, the consumer considers the relationship between each press portion and the longitudinal center line or the end edge of the absorbent body, You can not. This makes it difficult to recognize the positional displacement of the first and second pressing portions. Therefore, it is possible to make it difficult for the consumer to recognize the positional displacement of the pair of the pressing grooves in the width direction by the visual effect. However, if the relative relationship in the width direction between the two crimping portions is smaller than the above-mentioned predetermined range, it is not possible to influence the consciousness of the consumer, and if it is large, the position displacement of the crimping portion becomes conspicuous.

The absorbent article of the present invention is characterized in that (4) a first angle formed by a first reference line along the width direction of the first press portion and the longitudinal centerline, a second reference line along the width direction of the second press portion, The absorbent article according to any one of (1) to (3) above, wherein the second angle formed by the directional center line is not less than 30 degrees and not more than 150 degrees.

This makes it difficult to recognize the positional displacement of the first and second pressing portions. Therefore, it is possible to make it difficult for the consumer to recognize the positional displacement of the pair of the pressing grooves in the width direction by the visual effect. However, even if the magnitude of the first and second angles of the crimping portion is smaller or larger than the predetermined range, the first and second crimping portions are formed along the longitudinal direction, and the positional deviation of the crimping portion becomes conspicuous, Can not do it.

(5) The absorbent article according to (4), wherein an angle difference between the first angle and the second angle is not less than 0 degrees and not more than 40 degrees.

In this absorbent article, since the angular difference between the first angle and the second angle is in the above-described predetermined range, it is possible for the consumer not to be conscious of the relationship between each press-contact portion and the longitudinal center line or the end edge of the absorbent body. This makes it difficult to recognize the positional displacement of the first and second pressing portions. Therefore, it is possible to make it difficult for the consumer to recognize the positional displacement of the pair of the pressing grooves in the width direction by the visual effect. However, even if the angular difference between the first angle and the second angle of the press-contact portion is smaller or larger than the predetermined range, the consciousness of the consumer to one side or the other side of the longitudinal direction center line becomes excessively large and even if the positional deviation does not occur, There is a fear that it will be recognized as. In addition, uneven deformation occurs at the time of mounting, so that the absorbing performance is lowered, and there is a possibility that the wearer feels discomfort.

In the absorbent article according to the present invention, since the pressing portion is provided on the other side as well as one side in the longitudinal direction of the pair of pressing grooves, the consumer's consciousness can be directed to the first and second pressing portions and the third and fourth pressing portions, It is possible for the consumer to be less conscious of the relationship between the respective crimping portions and the longitudinal center line or the edge of the absorbent body. As a result, it is possible to make it more difficult to recognize the positional shifts of the first and second pressing portions and the positional shifts of the third and fourth pressing portions. By virtue of the visual effect, positional shifts in the width direction of the pair of pressing grooves It can make the consumer more difficult to recognize.

(8) The absorbent article of the present invention is characterized in that (8) a first angle and a second angle formed by the longitudinal center line and the first crimping portion and the second crimping portion of the plurality of crimping portions on the outer side, Wherein the first angle and the third angle are different from each other at a third angle and a fourth angle formed by the third squeezed portion and the second squeezed portion of the plurality of squeezed portions outside the first squeezed portion and the longitudinal centerline, The absorbent article described in (7) above may be different from the second angle and the fourth angle.

In this absorbent article, since the first angle, the second angle, the third angle and the fourth angle are different from each other, the arrangement state of the pressed portions on both sides in the longitudinal direction with respect to the pair of pressed grooves can be made different from each other . Therefore, the disposition states of the first to fourth pressing portions are made more uneven overall, and the consumer can be less conscious of the relationship between the respective press-bonding portions and the longitudinal edge center line or the end edge of the absorber. This makes it difficult to recognize the positional displacement of the first to fourth pressing portions. Therefore, it is possible to make the positional deviation of the pair of the pressing grooves in the width direction more difficult to recognize by the visual effect have.

(9) The absorbent article according to (8), wherein the first angle, the second angle, the third angle and the fourth angle are different from each other.

In this absorbent article, a virtual hexagon is formed to connect the first squeeze portion and the second squeeze portion, the both end edges in the width direction of the absorbent body, and the third squeeze portion and the fourth squeeze portion. In such a case, the consumer perceives the hexagon and grasps the positional relationship of the product based on the hexagon. Here, since this hexagon is not line-symmetrical with respect to the longitudinal center line, the reference becomes ambiguous, so that it is possible to make it difficult for the consumer to recognize the positional deviation even if the position of the pair of the pressing grooves actually deviates in the width direction. In addition, the movement of the excreted liquid in the longitudinal direction can be more effectively prevented by the first and second squeezing portions and the third squeezing portion and the fourth squeezing portion in a predetermined arrangement state. As a result, diffusion of the excreted liquid in the longitudinal direction is suppressed to reduce leakage, thereby improving the absorption performance.

In this absorbent article, the end edge of the absorbent article has a shape in which the outer edge that is convexly curved with respect to the outer side in the width direction and the outer edge that is concavely curved are alternately continuous, that is, a wavy shape. Therefore, it becomes difficult to recognize the distance between the end edge of the absorber and the pair of compression grooves. In such a case, even if the positions of the pair of the compression grooves are shifted in the width direction, it is difficult for the consumer to perceive that the displacement is the position displacement. That is, it is possible to make it difficult for the consumer to recognize the displacement in the width direction in the pair of compression grooves, so that the feeling that the absorbent article is good is not hindered.

According to the present invention, it is possible to provide an absorbent article which can make it difficult for the consumer to recognize the positional displacement even if the position of the compression groove is distorted in the width direction, without causing deterioration of the absorbing performance.

The fourth pressing portion 24 includes a groove 24M for forming a fourth pattern (for example, a butterfly) different from the third pattern when viewed from a plane, and the center of gravity G24 of the fourth pattern, Is located on the other side with respect to the longitudinal center line CL. The third pressing portion 23 and the fourth pressing portion 24 are different from each other in at least one of the position and the inclination relative to the longitudinal center line CL. The first pressing portion 21 and the third pressing portion 23 are provided on one end edge 3a of the absorbent 3 in the width direction W with the second pressing portion 22 and the fourth pressing portion 24 Face the other end edge 3b of the absorbent body 3 in the width direction W without passing through different compression grooves or the like.

Fig. 4 is a view showing the first to fourth squeezed portions, wherein Fig. 4 (a) shows the first and second squeezed portions, and Fig. 4 (b) shows the third and fourth squeezed portions. In the example shown in Fig. 4 (a), the pattern of the first crimping portion 21 (left side) is of a large ribbon shape and the pattern of the second crimping portion 22 (right side) is of a small ribbon shape. That is, the first crimping portion 21 has a ribbon shape by the groove 21M and has a size that can be repaired to the minimum rectangle R21 of the length TU21 × width WU21. On the other hand, the second crimping portion 22 has a ribbon shape formed by the groove 22M and has a size that can be repaired to the minimum rectangle R22 of the length TU22 × width WU22. In the example shown in Fig. 4 (b), the pattern of the third crimping portion 23 (left side) is a large butterfly shape (upside down), and the pattern of the fourth crimping portion . That is, the third pressing portion 23 has a shape of a butterfly shape by the groove 23M and has a size that is wetted by the smallest rectangle R23 of the vertical TU23 × horizontal WU23. On the other hand, the fourth pressing portion 24 has a ribbon shape by the groove 24M, and has a size that can be held in a minimum rectangular R24 of the length TU24 × width WU24.

In the example shown in Fig. 4A, the center of gravity of the first press portion 21 is G21, which is located at one side (left side) with respect to the longitudinal center line CL and the weight of the second press portion 22 The center is G22, and is located on the other side (right side) with respect to the longitudinal center line CL. That is, the first pressing portion 21 and the second pressing portion 22 are disposed such that the respective center of gravity G21 and G22 are divided into two sides with the longitudinal centerline CL therebetween. In the example shown in Fig. 4 (b), the center of gravity of the third press portion 23 is G23, which is located at one side (left side) with respect to the longitudinal center line CL, The center of gravity is G24, which is located on the other side (right side) with respect to the longitudinal center line CL. That is, the third pressing portion 23 and the fourth pressing portion 24 are disposed such that the respective center of gravity G23 and G24 are divided into two sides with the longitudinal center line CL therebetween.

4A, the relative position of the first crimping portion 21 is determined by the distance X21 in the width direction W with respect to the longitudinal center line CL and the distance X21 in the longitudinal direction center line CL, And the relative position of the second crimping portion 22 is a position X21 or Y21 defined by the position Y21 at the time of repetition of the distance L2 in the width direction W relative to the longitudinal centerline CL ) And a position (X22, Y22) specified by a position Y22 when a waterline is drawn on the longitudinal center line CL. In the example shown in Fig. 4 (b), the relative position of the third press portion 23 is determined by the distance X23 in the width direction W to the longitudinal center line CL, And the relative position of the fourth pressing portion 24 is a position X23 or Y23 defined by the position Y23 at the time of repetition of the distance X24 And a position (X24, Y24) specified by the position Y24 when the waterline is drawn on the longitudinal center line CL.

In the example shown in Fig. 3, the relative inclination of the first press portion 21 is set such that one side of the lower side of the rectangle in the longitudinal direction L is the first base line BL21, And a first center line GL21 (first reference line) passing through the center of gravity G21 and parallel to the center line CL21 with the longitudinal center line CL. The relative inclination of the second pressing portion 22 is set such that one side of the lower side of the rectangle in the longitudinal direction L is defined as the second base line BL22 and the center of gravity (Second reference line) passing through the longitudinal centerline CL and the second centerline GL22 (second reference line) passing through the longitudinal center line CL. The relative inclination of the third pressing portion 23 is set such that one side of the lower side of the rectangle in the longitudinal direction L is referred to as a third base line BL23 and parallel to the third base line BL23, And a third angle alpha 2 that the third center line GL23 (third base line) passing through the center G23 makes with the longitudinal centerline CL.

In this embodiment, in the examples shown in Figs. 1, 3, and 4, the shapes of the first pressing portion 21 and the second pressing portion 22 are the same. However, TU21? TU22 and WU21? WU22 are different patterns because of their different sizes (first crimping portion 21> second crimping portion 22). That is, the first crimping portion 21 and the second crimping portion 22 have different patterns. The relative positions X21 and Y21 of the first press portion 21 and the relative positions X22 and Y22 of the second press portion 22 are. X21? X22 and Y21? Y22, and the positions of the first pressing portion 21 and the second pressing portion 22 relative to the longitudinal center line CL are different from each other. The relative tilt? 1 of the first pressing portion 21 and the relative tilt? 1 of the second pressing portion 22 are? 1?? 1 and the first pressing portion 21 and the second pressing portion 22 Are arranged with different relative slopes with respect to the longitudinal center line CL.

As described above, in the present embodiment, the first pressing portion 21 and the second pressing portion 22 have different patterns and different positions and slopes relative to the longitudinal center line CL. Since there is a difference between the first pressing portion 21 and the second pressing portion 22 as described above, the absorbent article 1 of the present embodiment can exhibit the following operation effects.

5 (a) and 5 (b) are views for explaining the action and effect of the absorbent article. Fig. 5 (a) shows the case where there is no positional displacement of the press- Shows a case in which the position of the compression grooves is shifted and the first to fourth pressing portions are not respectively shown.

As shown in Fig. 5 (a), the first crimping portion 21 and the second crimping portion 22 are symmetrical with respect to the longitudinal center line CL in the shape of the pattern, the relative position or the inclination, no. In addition, the distance between one end edge 3a of the absorbent body 3 in the width direction W and the end portion of the pattern of the first pressed portion 21 and the widthwise direction W of the absorbent core 3 The distance between the end edge 3b of the first pressing portion 22 and the end portion of the pattern of the second pressing portion 22 is not equidistant. The consumer viewing these first and second pressing portions 21 and 22 is able to detect the longitudinal edge CL and the one end edge 3a of the width direction W of the absorbent body 3, It is unnecessary to be aware of the relationship of the other end edge 3b, in particular, whether or not it is line-symmetrical. 5 (b), the distance between one end edge 3a of the absorber 3 and the first press portion 21 and the distance between one end edge 3a of the absorber 3 and the absorber 3 in the width direction W, Even if the distance between the other end edge 3b and the second crimping portion 22 is not the same. Further, even if the position of the center between the first press portion 21 and the second press portion 22 and the position of the center position of the absorber 3 are misaligned, it is difficult to recognize that the position is misaligned. The distance between the center position between the first pressing portion 21 and the second pressing portion 22 and the distance between one end edge 3a of the absorbent 3 and the distance between the center of the first pressing portion 21 and the second pressing portion 22, Even if the distance between the center position between the center portion 22 and the other end edge 3b of the absorber 3 is not the same, The visual effect of the first pressing portion 21 and the second pressing portion 22 is such that the pair of the first pressing portion 21 and the second pressing portion 22 adjacent to each other in the longitudinal direction L 11b. 5 (b) in which the first crimping portion 21 and the second crimping portion 22 are provided is compared with the first crimping portion 21 and the second crimping portion 22, 5 (c) in which the first and second pressing portions 22 and 22 are not provided. That is, even if the positional deviation of the width direction W occurs in the pair of the compression grooves 11a and 11b adjacent to the first and second pressing portions 21 and 22 in the longitudinal direction L, It becomes difficult to recognize the positional deviation. That is, it is possible to make it difficult for the consumer to recognize the displacement of the width direction W in the pair of the compression grooves 11a, 11b.

At this time, the first pressing portion 21 and the second pressing portion 22 are pressed portions formed by pressing the topsheet 4 and the absorbent body 3 on the side of the topsheet 4, and the topsheet 4 The excreted liquid can be guided into the absorber 3 and the excreted liquid can move outside the longitudinal direction L in the excretory port contact area STA . Similarly, the pair of the compression grooves 11a and 11b is a compression groove formed by pressing the topsheet 4 and the absorbent body 3 on the side of the topsheet 4 in the same manner, The excreted liquid can be guided into the absorber 3 and movement of the excreted liquid outward in the width direction W from the excretory port contact area STA can be suppressed. The absorption performance of the absorbent article 1 can be maintained and improved by their synergistic effect.

As described above, in the present absorbent article, it is possible to make it difficult for the consumer to think that the absorbent article 3 is defective while maintaining the absorbent performance, so that the feeling that the absorbent article 1 is good article can be prevented.

In the present embodiment, as a preferred form, a pressing portion, that is, a third pressing portion 23 (not shown) is provided on one side (front side) of the longitudinal direction L of the pair of pressing grooves 11a and 11b as well as on the other side And a fourth pressing portion 24 are further provided. In the examples shown in Figs. 1, 3 and 4, the shape of the third pressed portion 23 and the fourth pressed portion 24 are the same as that of the butterfly. However, since TU23? TU24 and transverse WU23? WU24 are different in size (third crimping portion 23> fourth crimping portion 24), they are different patterns. That is, the pattern of the third crimping portion 23 and the pattern of the fourth crimping portion 24 are different. The relative positions X23 and Y23 of the third pressing portion 23 and the relative positions X24 and Y24 of the fourth pressing portion 24 are. X23? X24 and Y23? Y24, and the positions of the third pressing part 23 and the fourth pressing part 24 relative to the longitudinal center line CL are different from each other. The relative pressures of the third press portion 23 and the fourth press portion 24 are set at? 2? 2 at the relative inclination? 2 of the third press portion 23 and the relative inclination? 2 of the fourth press portion 24, Are arranged with different relative slopes with respect to the longitudinal center line CL.

In this case, the consciousness of the consumer can be directed not only to the first and second crimping portions 21 and 22, but also to the third and fourth crimping portions 23 and 24. At this time, the third pressing portion 23 and the fourth pressing portion 24 are different in position and inclination relative to the longitudinal center line CL. Therefore, the consumer who sees these third press portion 23 and fourth press portion 24 is able to grasp one end edge 3a of the longitudinal center line CL and the width direction W of the absorbent article 3, And the other end edge 3b, in particular, line symmetry. That is, the consumer can be less conscious of the relationship between the longitudinal center line CL and the end edge of the absorber 3 with respect to the respective crimping portions 23, 24. This makes it possible to make it more difficult to recognize the positional deviation of the first and second crimping portions 21 and 22 and the positional shift of the third and fourth crimping portions 23 and 24. By virtue of the visual effect, It is possible to make the position shift of the pair of the compression grooves 11a and 11b in the width direction W difficult to be recognized by the consumer. Although the third pressing portion 23 and the fourth pressing portion 24 are different in position and inclination relative to the longitudinal center line CL in the present embodiment, the positions of the third pressing portion 23 and the fourth pressing portion 24 relative to the longitudinal center line CL When either one of the slopes is different, the above effect can be exhibited.

Although the first pressing portion 21 and the second pressing portion 22 are different in position and inclination relative to the longitudinal center line CL in the present embodiment, the positions relative to the longitudinal center line CL When either one of the slopes is different, the above effect can be exhibited. The same applies to the third pressing portion 23 and the fourth pressing portion 24.

Although the first pressing portion 21 and the second pressing portion 22 are similar to each other in the present embodiment, they may be of different shapes. The same applies to the third pressing portion 23 and the fourth pressing portion 24. The first pressing portion 21, the second pressing portion 22, the third pressing portion 23, and the fourth pressing portion 24 may be similar to each other.

4 (a)) of the width direction W in each of the first pressing portion 21 and the second pressing portion 22 as a preferred embodiment of the present embodiment, Of the absorbent body 3 is not less than 1/10 and not more than 3/4 of the size d0 of the absorbent body 3 in the width direction W (see Fig. 3). More preferably, Wx21 and Wx22 are 1/5 or more and 3/5 or less of d0. In the example of Fig. 3, Wx21 and Wx22 are 1/2 and 1/4 of d0, respectively. In this case as well, it is possible to make it difficult to recognize the positional displacement of the first and second crimping portions 21 and 22, so that by virtue of the visual effect, the width direction W of the pair of crimping grooves 11a and 11b Can be made more difficult for the consumer to perceive. However, if the size (Wx21, Wx22) of the width direction W of the first and second crimping portions 21, 22 is smaller than the predetermined range, it can not affect the consciousness of the consumer, It is not preferable because the discrepancy becomes conspicuous.

4 (b)) of the width direction W in each of the third pressing portion 23 and the fourth pressing portion 24, as the preferred embodiment of the present embodiment, Of the absorbent body 3 is not less than 1/10 and not more than 3/4 of the size d0 of the absorbent body 3 in the width direction W (see Fig. 3). More preferably, Wx21 and Wx22 are 1/5 or more and 3/5 or less of d0. In the example of Fig. 3, Wx23 and Wx24 are 2/5 and 3/10 of d0, respectively. This makes it possible to make the position shift of the pair of the compression grooves 11a, 11b in the width direction W more difficult for the consumer to perceive.

As a preferred embodiment of the present embodiment, the size (Wx21 or Wx22) (see Fig. 4 (a)) of the width direction W of one side in the first pressing portion 21 and the second pressing portion 22 ) Is set to 25% or more and 400% or less of the size (Wx22 or Wx21) (see Fig. 4 (a)) of the other width direction W. For example, the size Wx21 of the width direction W of the first press portion 21 is not less than 25% and not more than 400% of the size Wx22 of the width direction W of the second press portion 22 . More preferably, Wx21 or Wx22 is 50% or more and 200% or less of Wx22 or Wx21. In the example of Fig. 4, Wx21 is 200% of Wx22. In this case as well, it is possible to make it difficult to recognize the positional displacement of the first and second crimping portions 21 and 22, so that by virtue of the visual effect, the width direction W of the pair of crimping grooves 11a and 11b Can be made more difficult for the consumer to perceive. However, if the relative relationship of the size of the width direction W between the first and second crimping portions 21 and 22 is smaller than the predetermined range, it can not affect the consciousness of the consumer, and if it is large, Is not preferable because it becomes noticeable.

As a preferred embodiment of the present embodiment, the size (Wx23 or Wx24) (see Fig. 4 (b)) in one of the width directions W of the third press portion 23 and the fourth press portion 24 is And 25% to 400% of the size (Wx23 or Wx24) (see Fig. 4 (b)) of the width direction W of the other side. More preferably, Wx21 or Wx22 is 50% or more and 200% or less of Wx22 or Wx21. In the example of FIG. 4, Wx23 is 133% of Wx24. As a result, it is possible to make the position shift of the pair of the compression grooves 11a and 11b in the width direction W less difficult for the consumer to recognize.

In the preferred embodiment of the present embodiment, the first center line GL21 (first reference line) along the width direction W of the first press portion 21 and the first center line CL the second angle beta 1 formed by the second center line GL22 (second reference line) along the width direction W of the second press portion 22 and the longitudinal center line CL is 30 DEG Or more and 150 DEG or less. More preferably not less than 45 ° and not more than 135 °, and still more preferably not less than 60 ° and not more than 90 °. In the example of Fig. 3,? 1 is 70 ° and? 1 is 70 °. In this case as well, it is possible to make it difficult to recognize the positional displacement of the first and second crimping portions 21 and 22, so that by virtue of the visual effect, the width direction W of the pair of crimping grooves 11a and 11b Can be made more difficult for the consumer to perceive. However, even if the first and second angles? 1 and? 1 are smaller or larger than the predetermined range, the first and second crimping portions 21 and 22 have a shape along the longitudinal direction L , The positional deviation of the pressed portion becomes conspicuous, which is not preferable.

As a preferred embodiment of the present embodiment, a third angle? L between the third center line GL23 (third base line) along the width direction W of the third press portion 23 and the longitudinal center line CL the fourth angle? 2 formed by the fourth center line GL24 (fourth reference line) along the width direction W of the fourth press portion 24 and the longitudinal center line CL is at least 30 degrees 150 DEG or less. More preferably not less than 45 ° and not more than 135 °, and still more preferably not less than 60 ° and not more than 90 °. In the example of Fig. 3,? 2 is 75 占 and? 2 is 65 占. This makes it possible to make the position shift of the pair of the compression grooves 11a, 11b in the width direction W more difficult for the consumer to perceive.

Further, as a preferred embodiment of the present embodiment, the angle difference between the first angle? 1 and the second angle? 1 is set to be not less than 0 ° and not more than 40 °. More preferably not less than 0 DEG and not more than 30 DEG, and still more preferably not less than 3 DEG and not more than 20 DEG. In the example of FIG. 3, the angle difference is 0 DEG. In this case as well, it is possible to make it difficult to recognize the positional displacement of the first and second crimping portions 21 and 22, so that by virtue of the visual effect, the width direction W of the pair of crimping grooves 11a and 11b Can be made more difficult for the consumer to perceive. However, even if the angular difference between the first angle? 1 and the second angle? 1 is smaller or larger than the predetermined range, the consciousness of the consumer to one side or the other side of the longitudinal center line CL becomes excessively large, There is a possibility that even if a shift does not occur, the shift may be recognized as a position shift. In addition, uneven deformation occurs at the time of mounting, and absorption performance is deteriorated, which may cause a wearer to feel discomfort.

Furthermore, as a more preferable embodiment in this embodiment, similarly, the angle difference between the third angle? 2 and the fourth angle? 2 is set to be not less than 0 ° and not more than 40 °. More preferably not less than 0 DEG and not more than 30 DEG, and still more preferably not less than 3 DEG and not more than 20 DEG. In the example of FIG. 3, the angle difference is 10 degrees. This makes it possible to make the position shift of the pair of the compression grooves 11a, 11b in the width direction W more difficult for the consumer to perceive.

In a preferred embodiment of the present embodiment, the first angle? 1 and the third angle? 2 are different, and the second angle? 1 and the fourth angle? 2 are different. In this case, the inclination relative to the arrangement direction of the first and second crimping portions 21, 22 on both sides of the longitudinal direction L, that is, the longitudinal direction center line CL with respect to the pair of crimping grooves 11a, Can be made different from each other. The arrangement of the first to fourth pressing portions 21 to 24 is made more uneven as a whole so that the consumer can easily grasp the lengthwise center line CL and the absorber portion 21, 22, 23, 3 and the end edges 3a, 3b of the end portions 3a, 3b can be made less conscious. As a result, it is possible to make it difficult to recognize the positional shifts of the first to fourth pressing portions 21 to 24. Therefore, by virtue of the visual effect, the widths of the pair of the pressing grooves 11a and 11b It is possible to make it difficult for the consumer to recognize the positional deviation of the wafer W more easily.

In the present embodiment, it is preferable that the first angle? 1, the second angle? 1, the third angle? 2 and the fourth angle? 2 are different from each other. In this case, the disposition states of the respective crimping portions 21, 22, 23, 24 on both sides in the longitudinal direction L of the pair of crimping grooves 11a, 11b can be made different from each other, W of the first and second crimping portions 21 and 22 and the arrangement of the third and fourth crimping portions 23 and 24 can be made different from each other. Therefore, the disposition states of the first to fourth pressing portions 21 to 24 are made more uneven overall, so that it is difficult to recognize the position deviations of the first to fourth pressing portions 21 to 24 It is possible to make the position deviation of the width direction W of the pair of the compression grooves 11a and 11b harder to be recognized by the consumer due to the visual effect.

In the preferred embodiment of the present invention, the size Wx21 of the width direction W of the first press portion 21, the width Wx22 of the width direction W of the second press portion 22, The size Wx23 of the width direction W of the third press portion 23 and the size Wx24 of the width direction W of the fourth press portion 24 are different from each other. In this case as well, the disposition states of the first to fourth pressing portions 21 to 24 are made more uneven overall, and the positional deviation of the first to fourth pressing portions 21 to 24 is recognized It is possible to make the position deviation of the width direction W of the pair of the compression grooves 11a and 11b harder to be recognized by the consumer because of the visual effect.

In the preferred embodiment of the present embodiment, the distance in the width direction W between the first crimping portion 21 and the second crimping portion 22 increases as it approaches the pair of crimping grooves 11a and 11b , And the distance in the width direction (W) between the third pressing portion 23 and the fourth pressing portion 24 increases as it approaches the pair of pressing grooves 11a and 11b. In other words, the first crimping portion 21 and the second crimping portion 22 are disposed apart from each other as they approach the pair of crimping grooves 11a and 11b, And is arranged in an inverted V-shape (substantially C-shaped). The third pressing part 23 and the fourth pressing part 24 are arranged to be closer to each other as they are closer to the pair of pressing grooves 11a and 11b and therefore, when viewed from the excretion accessory area STA, (Substantially crest-shaped). In this case, both ends 3a and 3b of the width direction W of the absorbent body 3 and the first and second pressing portions 21 and 22, the third and fourth pressing portions 23 and 23, And a virtual hexagon connecting the first and second electrodes 24 are formed. In such a case, the consumer perceives the hexagon and grasps the positional relationship of the product based on the hexagon. Here, since this hexagon is not line-symmetric with respect to the longitudinal center line CL, the criterion for grasping the positional relationship of the product becomes ambiguous. Therefore, even if the positions of the pair of the compression grooves 11a, 11b are actually shifted in the width direction W, it is possible to make it difficult for the consumer to recognize the positional deviation. In addition, the movement of the excreted liquid in the longitudinal direction L is performed by the first and second pressing portions 21 and 22 in the predetermined arrangement state, the third pressing portion 23 and the fourth pressing portion 24). As a result, diffusion of the excreted liquid in the longitudinal direction L is suppressed, and leakage is reduced, whereby the absorption performance can be improved. In other words, in the present absorbent article, it is possible to make it difficult for the consumer to think that the absorbent article 3 is defective while maintaining the absorbent performance, so that the feeling that the absorbent article 1 is good article can be prevented.

The absorber 3 is formed such that the end edges 3T1 and 3T2 of the longitudinal direction L extend along the substantially width direction W and outside the longitudinal direction L respectively A convex curved line convexly curved with respect to the outside of the longitudinal direction L and another concave curved line curved concavely with respect to the outside of the longitudinal direction L. [ At this time, the edges 3T1 and 3T2 each have a line-symmetrical shape with respect to the longitudinal center line CL, with the vertex at the outside of the longitudinal direction L of the convex curved line coinciding with the longitudinal center line CL. On the other hand, however, the end edges 3T1 and 3T2 of the absorber 3 can be regarded as curved lines of concave, convex, concave, and concave waves connected in this order. Therefore, the consumer perceives the edges 3T1 and 3T2 as continuous shapes, and it becomes difficult to recognize the center of the width direction W of the absorber 3. This effect and the effects of the first crimping portion 21 and the second crimping portion 22 synergistically act so that the positional deviation of the first crimping portion 21 and the second crimping portion 22 can be further It becomes more difficult to recognize. As a result, even if the positions of the pair of the compression grooves 11a and 11b are changed, the positional deviation can be hardly recognized.

The end edges 3T1 and 3T2 of the absorbent core 3 in the longitudinal direction L of the absorbent core 3 may be formed in such a manner that the end edges 3T1 and 3T2 of the absorbent core 3 in the longitudinal direction L of the body portion 2a (2T1, 2T2) is not constant along the width direction (W). The end shape of the absorber 3 in the longitudinal direction L does not resemble that of the end portion in the longitudinal direction L of the main body 2a. Here, the end portion of the body portion 2a in the longitudinal direction L is formed by the topsheet 4 and the backsheet 5. Thus, the distance between the end portion of the absorbent core 3 and the end portion of the topsheet 4 and the backsheet 5 is not constant, and the end shapes of both are not similar to each other. The top portion of the end portion in the longitudinal direction L of the absorber 3 and the top portion in the end portion in the longitudinal direction L of the main portion 2a are mutually twisted in the width direction W It is possible to make the position deviation more difficult to recognize. The effect of the first pressing portion 21 and the effect of the second pressing portion 22 acts synergistically so that the positional deviation of the first pressing portion 21 and the second pressing portion 22 can be prevented It becomes more difficult to recognize. As a result, even if the positions of the pair of the compression grooves 11a and 11b are changed, the positional deviation can be hardly recognized.

Next, an example of a method of manufacturing the absorbent article 1 will be described. 6 is a schematic diagram showing a configuration of an apparatus 300 for manufacturing an absorbent article 1. The manufacturing apparatus 300 includes a first forming unit 300A for performing a first forming process, a second forming unit 300B for executing a second forming process, a third forming unit 300B for executing a third forming process, A second forming unit 300C, and a fourth forming unit 300D that performs a fourth forming process. A method of manufacturing an absorbent article includes a first forming step to a fourth forming step. In this example, each material is formed and transported such that the width direction W of the absorbent article 1 is in the transport direction MD. In this case, since the width of the absorber 3 is relatively short, in the step of forming the first pressing portion 21 to the fourth pressing portion 24 and the pair of pressing grooves 11a and 11b, The first pressing portion 21 to the fourth pressing portion 24 and the pair of pressing grooves 11a and 11b are liable to be displaced in the conveying direction W in the conveying direction MD. Therefore, the structure of the absorbent article 1 of the present embodiment is very effective. However, each material may be formed and transported such that the longitudinal direction L of the absorbent article 1 is in the transport direction MD.

In the first forming step, the rotating drum 111 of the stacking unit 110 is rotated so that the accumulated material supplied from the material supplying unit 113 is communicated with the negative pressure chamber 111N of the pattern plate 112 And is deposited in the groove, thereby forming a laminate AB in the groove. Subsequently, when the pattern plate 112 reaches the static pressure chamber 111P together with the enemy line body AB, the enemy line body AB is released from the pattern plate 112.
