(1) Summary of embodiment

At least the following matters become clear from description of this specification and accompanying drawings.

The absorbent article according to an aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, a back sheet directed toward a side opposite to the wearer's skin, an adhesive portion formed on the non-skin side of the back sheet, and post-treatment It has a tape member for dragon. The absorbent article has an article centerline extending in the front-rear direction past the center of the absorbent article in the width direction, and the tape member for post-treatment includes a front edge of the absorbent article or The tape member has a tape center line extending in an extension direction of the tape member past the center of the tape member, and the tape member includes the tape center line, the tape When the member is extended, it is configured to shift in the width direction or obliquely with respect to the article center line.

According to this aspect, the tape member for post-treatment is configured to shift in the width direction or obliquely with respect to the article center line when the tape member is extended. Therefore, when fixing the tape member for post-treatment to the absorbent article aggregated in the front-rear direction, a load is applied to a position shifted from the center of the width direction of the absorber, or a strong load is applied locally to the center of the width direction of the absorber. Without losing, the load is distributed in the width direction of the absorber. Thereby, it is possible to suppress that a load is locally applied to the center of the absorber in the width direction, and it becomes difficult for body fluid to seep out of the absorber during operation of the tape member for post-treatment.

In a preferred embodiment, a portion of the tape member passes through the article centerline.

When the tape member is fixed to the absorbent article at one end in the width direction of the absorbent article that has been aggregated, the other end in the width direction of the absorbent article may be opened. According to this aspect, since a part of the tape member passes the article center line, the absorbent article aggregated can be firmly fixed in the vicinity of the center of the absorbent article in the width direction. On the other hand, even in this case, since the tape member for post-treatment is configured to be shifted in the width direction or obliquely with respect to the center line of the article when the tape member is extended, body fluid permeates from the absorber during operation of the tape member for post-treatment. The merit that it is difficult to come out is obtained.

According to a preferred embodiment, the tape member is disposed to be shifted in the width direction with respect to the article center line, and the adhesive portion is on both sides of the center line of the absorbent article in a region other than on the center line of the absorbent article. Is formed in

The center of the absorbent article in the width direction is a portion facing a concave portion such as a blunt hiatus of the wearer. Since the adhesive portion is not formed in this portion, the center of the absorbent article in the width direction is not directly fixed to a worn article such as underwear. Therefore, when a force is received from both legs of the wearer in the width direction, the center of the absorbent article in the width direction is deformed into a convex shape toward a concave portion such as the wearer's blunt tear, and the absorbent article is easy to fit the wearer's skin Lose.

Even in this case, since the tape member is arranged to be shifted in the width direction with respect to the product center line, the area where the tape member and the adhesive portion overlap when viewed from the front-rear direction can be widened (see Fig. 2). Therefore, when the tape member is extended in a state where the absorbent article is bundled, it is possible to easily fix the tape member to the adhesive portion.

According to a preferred aspect, the tape center line is obliquely inclined with respect to the article center line when the tape member is extended, and an inclination angle between the tape center line and the article center line is 10° or less.

By reducing the inclination angle between the tape center line and the article center line, the tape member can be easily pulled out in the front-rear direction. Thereby, it becomes easy to fix the absorbent article aggregated in the front-rear direction with the tape member.

The absorbent article according to another aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, a back sheet directed toward a side opposite to the wearer's skin, an adhesive portion formed on the non-skin side of the back sheet, and a rear It has a tape member for processing. The absorbent article has an article centerline extending in the front-rear direction past the center of the absorbent article in the width direction, and the tape member for post-treatment includes a front edge of the absorbent article or It is configured to extend outward from the rear edge. The tape member has a fixing portion fixed to the back sheet, and a non-fixing portion not fixed to the back sheet. The non-fixing portion is disposed on a side opposite to the extending direction of the tape member with respect to the fixing portion, and a boundary between the fixing portion and the non-fixing portion is obliquely inclined with respect to the width direction.

Since the boundary between the fixed portion and the non-fixed portion is obliquely inclined with respect to the width direction, the tape center line of the tape member drawn out in the extension direction can be obliquely inclined with respect to the article center line.

According to a preferred embodiment, the plurality of adhesive portions extend along the front-rear direction and are formed at intervals from each other in the width direction.

When the tape center line of the tape member pulled out in the extension direction is obliquely inclined with respect to the product center line, the length in the article width direction of the tape member pulled out in the extension direction is the width of the tape member in a direction orthogonal to the extension direction Becomes longer than Therefore, when a plurality of adhesive portions are formed at intervals from each other in the width direction, the tape member can be fixed over a plurality of adhesive portions without excessively widening the width of the tape member. Thereby, it becomes easy to hold the absorbent article tightly in a bundled state.

According to a preferred aspect, the tape member is disposed so as not to protrude from the absorbent article as viewed from the thickness direction.

Since the tape member does not protrude from the absorbent article during wearing of the absorbent article, the tape member does not directly contact the wearer's skin. Therefore, the feeling of discomfort during wearing can be suppressed.

Hereinafter, an absorbent article according to an embodiment will be described with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, a panty liner, a breast milk pad, an adult incontinence pad, a feces pad, or a sweat sheet. In particular, the absorbent article may be an article attached to the inside of a worn article such as an undergarment of a user and used.

In addition, in the description of the following drawings, the same or similar reference numerals are attached to the same or similar parts. However, it should be noted that the drawings are schematic and that the ratio of each dimension may be different from that of the actual one. Therefore, specific dimensions and the like should be determined in consideration of the following description. In addition, there are cases in which parts having different dimensional relationships and ratios between the drawings are also included.

1 is a plan view of an absorbent article according to a first embodiment as viewed from the skin surface side. 2 is a plan view of the absorbent article according to the first embodiment as viewed from the non-skin surface side. 3 is a perspective view of the absorbent article according to the first embodiment in a state that is rolled in the front-rear direction. Here, the "skin surface side" corresponds to the side facing the wearer's skin during use. The "non-skin surface side" corresponds to the side facing the wearer's skin during use.

The absorbent article 10 has a front-rear direction (L) and a width direction (W). The anteroposterior direction L is a direction extending from the front side (abdominal side) of the wearer to the rear side (back side), or a direction extending from the rear side of the wearer to the front side. The width direction W is a direction orthogonal to the front-rear direction L. The absorbent article 10 has an article center line CL1 extending in the front-rear direction L past the center of the absorbent article 10 in the width direction W.

The absorbent article 10 includes a top sheet 20 facing the wearer's skin, a back sheet 22 facing away from the wearer's skin, and an absorber between the top sheet 20 and the back sheet 22 It has a main body including 30. The top sheet 20 faces toward the wearer's skin during use. During use, the back sheet 22 is directed to the side opposite to the wearer's skin. The top sheet 20 may be constituted by a liquid permeable sheet. The back sheet 22 may contain a liquid impermeable sheet.

The absorbent body 30 extends along the front-rear direction L of the absorbent article. The absorbent body 30 may include an absorbent core composed of an absorbent material capable of absorbing moisture, and a core wrap surrounding the absorbent core. The core wrap can be constituted by, for example, a tissue.

The absorbent article 10 may have a wing 40 and a hip flap 50. The wing 40 is folded back to the non-skin surface side of the crotch portion of the worn article during use. The hip flap 50 is a portion that is bulged in the width direction W from the rear of the wing 40. The hip flap 50 is a portion bulging outward from the outer edge of the absorber 30 in the width direction W.

The absorbent article 10 has an excretory mouth facing region S1 that faces an excretory mouth (for example, a vaginal mouth) of the wearer during use. The excretory mouth facing region S1 is a region disposed between the wearer's crotch, that is, the wearer's legs, and corresponds to a region in which the absorbent body 30 exists. On the other hand, in the absorbent article 10 having the wings 40, the area S1 facing the excretory port is between the wings 40 and corresponds to a region in which the absorbent body 30 exists.

As shown in FIG. 2, the absorbent article 10 has adhesive portions 42, 52, and 70 formed on the non-skin side of the back sheet 22. The adhesive portions 42, 52, and 70 are regions in which an adhesive for fixing the absorbent article 10 to the worn article is formed. The adhesive portion includes a body adhesive portion 70, a wing adhesive portion 42, and a flap adhesive portion 52.

By the adhesive portions 42, 52, and 70 formed on the non-skin surface side of the back sheet 22, the absorbent article can be fixed to the wearer's shorts and the like. When the absorbent article is rolled up after use of the absorbent article 10, the tape member 60 for post-treatment may be fixed to the adhesive portions 42, 52, 70. Accordingly, the adhesive portions 42, 52, and 70 can be used both for fixing to a garment and for fixing a tape member for post-treatment.

The body adhesive portion 70 is formed in a region overlapping the absorbent body 30 in the thickness direction of the absorbent article. It is preferable that the main body adhesive portion 70 extends continuously or intermittently to the rear of the absorbent article 10 at least from the excretory port facing region S1. The body adhesive portion 70 extends in the front-rear direction (L) and may be formed in plural at intervals in the width direction (W).

The wing adhesive portion 42 is formed on the wing 40. The wing 40 is folded back into an article worn by the wearer during use, and is attached to the non-skin surface side of the worn article by the wing adhesive portion 42. The flap adhesive portion 52 is formed on the hip flap 50.

The absorbent article 10 may have at least two folding lines extending along the width direction W. In the example shown in Figs. 1 and 2, the absorbent article 10 has three fold lines F1 to F3. These fold lines F1 to F3 are lines for folding the absorbent article when packaging the absorbent article.

The absorbent article 10 further has a tape member 60 disposed on the non-skin surface side of the back sheet 22 inside than the outer edge of the absorbent article 10. It is preferable that the tape member 60 is in a state that does not protrude from the absorbent article 10 when viewed from the skin surface side. Thereby, since the tape member 60 does not directly contact the wearer's skin while the absorbent article 10 is being worn, a feeling of incongruity in wearing can be suppressed.

In this embodiment, the tape member 60 for post-treatment is formed behind the main body adhesive part 70. In this case, the tape member 60 may be configured to be extendable to the rear side from the rear end edge E2 of the absorbent article 10 along the front-rear direction L. Instead, the tape member 60 for post-treatment may be formed on the front side of the main body adhesive portion 70. In this case, the tape member 60 may be configured to be extendable to the front side from the front end edge E1 of the absorbent article 10 along the front-rear direction L. In the meantime, in the present specification, the term "along the front-rear direction (L)" means a direction having an angle of less than 45° with respect to the front-rear direction (L).

The tape member 60 has a fixing portion 62 fixed to the back sheet 22 and a non-fixing portion 64 that is not fixed to the back sheet 22. The tape member 60 is permanently attached to the back sheet 22 by the fixing portion 62. The fixing portion 62 is defined by a portion applied with an adhesive for permanently bonding the tape member 60 to the back sheet 22.

The surface of the non-fixing portion 64 of the tape member 60 may not have a fixing means such as an adhesive material, and may be configured to be floatable from the back sheet 22. Instead, the non-fixing portion 64 of the tape member 60 may be temporarily fixed to the back sheet 22. Temporarily fixing to the back sheet 22 can be peeled off with a relatively weak force. After the use of the absorbent article 10, the user maintains the absorbent article 10 in a packed state by fixing the extended tape member 60 to the adhesive portion 70 formed on the other portion of the back sheet 22. Can (see Fig. 3).

When the absorbent article 10 is disposed, the tape member 60 may be configured to be fixed to the body portion in a dried state with the skin-facing surface side of the absorbent article inwardly to keep the absorbent article 10 in a rolled state. . The non-fixing portion 64 of the tape member 60 is configured to be fixed to the body portion. The configuration in which the non-fixing portion 64 is fixed to the body portion may be an adhesive portion of the body portion, or a fixing means such as an adhesive formed on the tape member 60 or a hook member may be used. Further, the fixing portion 62 of the tape member 60 may be configured to be capable of being fixed to the body portion. The configuration in which the fixing portion 62 is fixed to the body portion may be an adhesive portion of the body portion, or may be a fixing means such as an adhesive formed on the tape member 60 or a hook member.

An example of a specific configuration of the absorbent article of this embodiment is shown. The top sheet may be formed of an air-through nonwoven fabric (PE/PET) having a basis weight of 30 g/m 2. A second sheet may be formed between the top sheet and the absorbent core. As the second sheet, it may be made of the same material as the top sheet. Outside of the body portion in the width direction, a top sheet may not be disposed, but a side sheet may be disposed. As a side sheet, you may comprise SMS nonwoven fabric (PP) with a basis weight of 13 g/m 2. The absorbent material of the absorbent core may be composed of softwood kraft pulp and a super absorbent polymer. The ratio of the weight of the superabsorbent polymer to the total weight of the absorbent material may be 10%. The basis weight of the absorbent core in the region including the excretion port facing region S1 may be configured to be higher than that of the surrounding absorbent core. The basis weight of the absorbent core in the region including the excretory facing region S1 may be 950 g/m 2, and the basis weight of the surrounding absorbent core may be 300 g/m 2. The back sheet may be formed of a polyethylene film (non-ventilated type) having a basis weight of 23.5 g/m 2. The absorbent article may have a pressing portion formed by pressing the top sheet and the absorbent core in the thickness direction. The body adhesive portion may be formed of a rubber-based hot melt adhesive. The basis weight of the body adhesive portion may be 27 g/m 2. Six main body adhesive portions may be formed at intervals in the width direction. The length of each body adhesive portion in the width direction may be 5 mm, and the length of each body adhesive portion in the front-rear direction may be 320 mm. The length in the front-rear direction of the absorbent article may be 420 mm, and the length in the width direction of the absorbent article may be 200 mm. The tape member for post-treatment may be made of a polyethylene film having a basis weight of 35 g/m 2. The length of the tape member in the longitudinal direction may be 45 mm, and the length of the tape member in the width direction may be 25 mm. The tape member may be fixed to the main body with a rubber-based hot melt adhesive having a basis weight of 100 g/m 2. The adhesive may be applied in a range of 21 mm in width and 5 mm in length. Printing may be performed on the side of the back sheet side of the tape member. For printing, a pink urethane-based ink may be used. The stretchable tape member may be formed by lamination of a polypropylene layer having a basis weight of 10 g/m 2, a styrene rubber layer having a basis weight of 10 g/m 2, and a polypropylene layer having a basis weight of 10 g/m 2.

The non-fixing portion 64 of the tape member 60 may be disposed on the side opposite to the extending direction of the tape member 60 with respect to the fixing portion 62. That is, the fixing part 62 may be located farther from the center of the absorbent article in the front-rear direction L than the non-fixing part 64. In this case, the user pulls the tape member 60 so that the non-fixing portion 64 of the tape member 60 is folded back at the boundary between the fixed portion 62 and the non-fixing portion 64.

The tape member 60 is arranged to be shifted in the width direction W with respect to the article center line CL1. In other words, the tape center line CL2 of the tape member 60 is configured to shift in the width direction W with respect to the article center line CL1 when the tape member 60 is extended. Here, the tape center line CL2 is a line extending in the tension direction of the tape member 60 and passing through the center of the tape member 60 in a direction orthogonal to the tension direction. In this case, when fixing the tape member 60 for post-treatment to the absorbent article 10 aggregated in the front-rear direction (L), a load is applied to a position shifted from the center of the width direction (W) of the absorber 30 . As a result, it is possible to suppress a locally strong load from being applied to the center of the absorber 30 in the width direction W, and it becomes difficult for moisture to seep out of the absorber during operation of the tape member 60 for post-treatment. .

It is preferable that a part of the tape member 60 passes through the article center line CL1. If the tape member 60 is fixed to the absorbent article 10 near one end in the width direction W of the absorbent article 10, the absorbent article 10 in the width direction W The other end may open up. When a part of the tape member 60 passes the article center line CL1, the absorbent article 10 aggregated can be firmly fixed near the center of the absorbent article 10 in the width direction W. On the other hand, even in this case, since the tape member 60 for post-treatment is arranged to deviate from the product center line CL1, a strong load is suppressed from being applied to the center of the absorber 30 in the width direction W. .

It is preferable that the main body adhesive portion 70 is formed on both sides of the absorbent article 10 with respect to the article centerline CL1 in a region other than the article centerline CL1 of the absorbent article 10. The article center line CL1 is a portion facing a concave portion such as a blunt hiatus of the wearer. Since the body adhesive portion 70 is not formed on the article center line CL1, the center of the absorbent article in the width direction is not directly fixed to a worn article such as an undergarment. Therefore, when a force is received from both legs of the wearer in the width direction, the center of the absorbent article 10 in the width direction is deformed into a convex shape toward a concave portion such as a blunt of the wearer, so that the absorbent article is applied to the wearer's skin It becomes easy to fit. In addition, even in this case, since the tape member 60 is arranged to be shifted in the width direction W with respect to the product center line CL1, the tape member 60 and the body adhesive portion 70 are viewed from the front-rear direction L. The overlapping area can be widened (see FIG. 2). Therefore, when the tape member 60 is extended while the absorbent article 10 is bundled together, the tape member 60 can be easily fixed to the main body adhesive portion 70.

(3) Second embodiment

Next, the absorbent article according to the second embodiment will be described. 4 is a plan view of the absorbent article according to the second embodiment as viewed from the non-skin surface side. 5 is a perspective view of the absorbent article according to the second embodiment in a state that is rolled in the front-rear direction. In Figs. 4 and 5, the same reference numerals are attached to the same members as in the first embodiment. Hereinafter, description of the same configuration as in the first embodiment may be omitted.

In the second embodiment, the tape member 60 is configured such that the tape center line CL2 is obliquely shifted from the article center line CL1 when the tape member 60 extends. Here, the tape center line CL2 is a line extending in the tension direction of the tape member 60 and passing through the center of the tape member 60 in a direction orthogonal to the tension direction. Specifically, the tape member 60 may be inclined obliquely with respect to the article center line CL1. In this case, the user pulls the tape member 60 along the tape center line CL2 when fixing the bundled absorbent article 10 with the tape member 60. The tape member 60 is fixed to the main body adhesive portion 70 in a state inclined at an angle with respect to the tape center line CL2. In this case, the load applied from the tape member 60 to the absorber 30 is distributed in the width direction W by the amount where the tape member 60 is obliquely inclined. Thereby, it is possible to suppress that a load is locally applied to the center of the absorber 30 in the width direction W, and it becomes difficult for the body fluid to seep out of the absorber during operation of the tape member 60 for post-treatment.

Also in the second embodiment, it is preferable that a part of the tape member 60 passes through the article center line CL1. Thereby, in the vicinity of the center in the width direction W of the absorbent article 10, the absorbent article 10 aggregated can be firmly fixed. On the other hand, even in this case, since the tape member 60 for post-treatment is obliquely inclined with respect to the article center line CL1 when the tape member 60 is extended, it is possible to distribute the load applied to the absorber 30 It is possible.

It is preferable that the inclination angle between the tape center line CL2 and the article center line CL1 is preferably 10 degrees or less. Thereby, even at the time of extension of the tape member 60, the inclination angle between the tape center line CL2 and the article center line CL1 becomes 10 degrees or less. If the inclination angle between the tape center line CL2 and the article center line CL1 is large, the tape member 60 is pulled in a direction greatly inclined from the front-rear direction to the absorbent article 10 aggregated in the front-rear direction. , It is difficult for the user to pull the tape member 60. In this embodiment, by reducing the inclination angle between the tape center line CL2 and the article center line CL1, the tape member 60 can be easily pulled out along the front-rear direction L.

As shown in FIG. 5, it is preferable that the body adhesive portion 70 extends along the front-rear direction (L) and is formed at intervals from each other in the width direction (W). Here, when the tape center line CL2 of the tape member 60 is obliquely inclined with respect to the article center line CL1, the length L1 in the width direction W of the tape member 60 drawn in the extension direction (absorbent article The length in the width direction of) becomes longer than the width W1 of the tape member in the direction orthogonal to the extension direction. Therefore, in the case where the plurality of main body adhesive portions 70 are formed at intervals from each other in the width direction W, the tape member 60 is not excessively widened, and the width W1 of the tape member 60 is not increased. It can be fixed over a plurality of body adhesive portions 70 (see also FIG. 5). Thereby, it becomes easy to hold the absorbent article 10 tightly in a bundled state.

(4) 3rd embodiment

Next, the absorbent article according to the third embodiment will be described. 6 is a plan view of the absorbent article according to the third embodiment as viewed from the non-skin surface side. In Fig. 6, the same reference numerals are attached to the same members as in the second embodiment. Hereinafter, the description may be omitted for the same configuration as in the second embodiment.

In the third embodiment, the non-fixing portion 64 of the tape member 60 is disposed on the side opposite to the extending direction of the tape member 60 with respect to the fixing portion 62. That is, the fixing portion 62 of the tape member 60 is located farther from the center of the absorbent article 10 in the front-rear direction L than the non-fixing portion 64. Further, the boundary BL between the fixing portion 62 and the non-fixing portion 64 is obliquely inclined with respect to the width direction W.

The user pulls the tape member 60 so that the non-fixing portion 64 of the tape member 60 is folded back at the boundary BL between the fixed portion 62 and the non-fixing portion 64. Here, in Fig. 6, a virtual outline IL when the tape member 60 is folded back at the boundary BL is drawn by a dotted line. As described above, since the boundary BL between the fixing portion 62 and the non-fixing portion 64 is inclined, the tape center line CL2 of the tape member 60 drawn in the extension direction is obliquely with respect to the article center line CL1. It is inclined. The effect obtained by obliquely inclining the tape center line CL2 of the tape member 60 drawn out in the extending direction with respect to the article center line CL1 is the same as described in the second embodiment.

It is preferable that the inclination angle between the boundary BL of the fixed part 62 and the non-fixing part 64 and the width direction W is 10 degrees or less. Thereby, at the time of extension of the tape member 60, the inclination angle between the tape center line CL2 and the article center line CL1 becomes 10 degrees or less. Therefore, as in the second embodiment, the tape member 60 can be easily pulled out along the front-rear direction L.

In the above, the present invention has been described in detail using the above-described embodiments, but it is clear to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as a modified and modified embodiment without departing from the spirit and scope of the present invention determined by the description of the claims.
