Japanese Patent Laid-Open No. 2012-183379

When the absorbent article is worn, various forces are applied to the absorbent article due to movement of the legs, etc. In a configuration where the separate mechanical fastening elements and the back sheet are integrated, the rigidity of the connection portion between the mechanical fastening elements and the back sheet is likely to be low. That is, in the entire back member including the mechanical fastening element and the back sheet, portions with low rigidity are formed locally. Therefore, when various forces are applied to the absorbent article, there is a risk that the low-rigidity portion may break locally, making it impossible to maintain the latching state of the absorbent article.

Accordingly, an absorbent article is provided that suppresses breakage of the hook portion that catches and secures the worn article, and makes it easy to maintain a hooked state with respect to the worn article.

An absorbent article according to one aspect includes a liquid-impermeable backsheet that is in contact with a wearing article in the front-back and width directions, an absorbent core disposed on a skin-surface side relative to the backsheet, and an absorbent core disposed on a skin-surface side relative to the absorbent core. Provided with a surface sheet. The backsheet has a base portion extending in a plane direction including the front-back direction and the width direction, and a hook portion that protrudes from the base portion toward the non-skin surface side and is hooked and fixed to the wearing article. The hook portion is the same member as the base portion and is formed continuously with the base portion.

(1) Overview of embodiment

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

An absorbent article according to one aspect includes a liquid-impermeable backsheet that is in contact with a wearing article in the front-back and width directions, an absorbent core disposed on a skin-surface side relative to the backsheet, and an absorbent core disposed on a skin-surface side relative to the absorbent core. Provided with a surface sheet. The backsheet has a base portion extending in a plane direction including the front-back direction and the width direction, and a hook portion that protrudes from the base portion toward the non-skin surface side and is hooked and fixed to the wearing article. The hook portion is the same member as the base portion and is formed continuously with the base portion. According to this aspect, the absorbent article can be hung and fixed to a wearing article via the hook portion protruding toward the non-skin surface side of the base portion. When the absorbent article is worn, various forces are applied to the absorbent article due to movement of the legs, etc. At this time, since the hook portion is the same member as the base portion and the hook portion is formed continuously with the base portion, it is difficult to create a locally low rigidity portion such as a connection portion between the hook portion and the base portion. Therefore, when various forces are applied to the absorbent article, the entire back sheet receives the force, and local breakage of the hook portion can be suppressed. By suppressing breakage of the hook portion, it becomes easier to maintain a latched state for the worn article.

According to one preferred aspect, a plurality of the hook portions are arranged at intervals in the front-back direction and the width direction. The height of the plurality of hook portions is constant. In a configuration with hook portions of different heights, the force applied to the hook portions may be uneven due to the difference in height, and force may be applied locally to some hook portions, which may cause some of the hook portions to break. However, according to this aspect, since the height of the plurality of hook portions is constant, unevenness of force due to difference in height can be suppressed, and force can be received on the entire back sheet, thereby suppressing local breakage of the hook portion.

According to one preferred aspect, the plurality of absorbent articles are individually packaged with packaging sheets in a folded state with the plurality of fold marks as the starting point. In the folded state, at least a portion of the back sheet is covered by the packaging sheet, and the hook portion engages the packaging sheet. According to this aspect, the hook portion can be protected by covering the hook portion before use with the packaging sheet. The problem of the hook portion being unintentionally caught on the surface sheet, etc. before use of the absorbent article can be suppressed.

According to a preferred embodiment, in an unfolded state in which the plurality of folds are not folded, the back sheet is covered over the entire surface by the packaging sheet. According to this aspect, the entire hook portion before use can be covered with the packaging sheet, thereby protecting the hook portion. This can prevent the problem of the hook portion being unintentionally caught on the surface sheet, etc. before use of the absorbent article.

According to a preferred embodiment, the back sheet has an uncovered area that is not covered by the packaging sheet in an unfolded state in which the plurality of fold marks are not the starting point. In the folded state, the hook portion of the uncovered area is engaged with the top sheet. According to this aspect, in the folded state, the hook portions in the uncovered area can be covered with the top sheet, and the hook portions other than the uncovered area can be covered with the back sheet. This can prevent the problem of the hook portion being unintentionally caught on the surface sheet, etc. before use of the absorbent article.

According to one preferred aspect, the hook portion is disposed over the entire surface of the core arrangement area overlapping the absorbent core in the thickness direction. According to this aspect, the absorbent article can be hung and fixed to the wearing article via the hook portion over the entire core arrangement area. The entire area where the absorbent core for absorbing body fluid is disposed becomes difficult to float from the worn article, preventing problems such as body fluid unintentionally adhering to the body or leaking body fluid.

According to one preferred aspect, the flap portion is disposed outside the core arrangement area in the width direction and bulges outward in the width direction. The hook portion is disposed on the flap portion. The flap portion does not have an absorbent core disposed thereon, has lower rigidity compared to the core disposition area, and may become twisted when worn. However, according to this aspect, since the hook portion is disposed on the flap portion, the flap portion can also be hooked and fixed to the article to be worn via the hook portion, thereby preventing the flap portion from twisting when worn.

According to one preferred aspect, the hook portion may be disposed over the entire surface of the backsheet. According to this aspect, since the backsheet is disposed on the front of the absorbent article and the hook portion is disposed over the entire surface of the backsheet, the front of the absorbent article can be hooked and fixed to the wearing article via the hook portion.

According to a preferred aspect, the thickness of the base portion may be thicker than the height of the hook portion. Since the base portion is thicker than the hook portion, the ratio contributing to the rigidity of the backsheet is likely to be higher in the base portion than in the hook portion. The base portion extends in a planar direction over the entire back sheet. In contrast, the hook portions are arranged at intervals in the planar direction, and a difference in rigidity occurs in the back sheet depending on the presence or absence of the hook portion. However, since the ratio contributing to the rigidity of the backsheet is higher in the base portion than in the hook portion, the difference in rigidity due to the presence or absence of the hook portion is less likely to contribute to the rigidity of the entire backsheet, making it possible to suppress unevenness in the rigidity of the backsheet. Accordingly, by suppressing the imbalance in the rigidity of the backsheet, local breakage of the hook portion can be suppressed, and it becomes easy to maintain the latching state for the worn article.

In addition, for convenience of explanation, the hook portion is omitted in FIG. 2 . The absorbent article 1 has a front-back direction (L), a width direction (W), and a thickness direction (T). The anteroposterior direction L is a direction extending from the front side (ventral side) of the wearer to the back side (dorsal 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-back direction (L). The thickness direction T is a direction extending to the skin surface side (T1) and the non-skin surface side (T2). Here, the “skin surface side” corresponds to the side that faces the wearer's skin during use. The “non-skin surface side” corresponds to the side that faces away from the wearer’s skin during use.

The absorbent article 1 has a crotch area S2, a front area S1, and a rear area S3. The area below the crotch (S2) is an area disposed opposite to the wearer's excretory opening, for example, the vaginal opening. When the absorbent article 1 is attached to a wearing article, the under-crotch area S2 is an area disposed below the crotch of the wearing article and between the wearer's legs. The anterior region S1 is located anterior to the infracrotch region S2. The shear edge of the front region S1 defines the shear edge of the absorbent article 1. The rear region S3 is located posterior to the crotch region S2. The rear edge of the rear region S3 defines the rear edge of the absorbent article 1.

A wing portion 25 may be provided in the crotch area S2. The wing portion 25 extends outward from the absorbent core 30 in the width direction W, and is folded toward the non-skin surface side T2 of the wearing article during use. The wing portion 25 may have a top sheet 10 and a back sheet 20. The shear edge of the wing portion 25 is defined by the die portion of the wing portion 25, and corresponds to the portion located on the front side among the two portions that are recessed inward in the width direction W. The front edge of the wing portion 25 may define the boundary between the crotch area S2 and the front area S1. The rear end edge of the wing portion 25 is defined by the ridge portion of the wing portion 25, and corresponds to the portion located at the rear of the two portions that are recessed inward in the width direction W. The rear edge of the wing portion 25 may define the boundary between the under-crotch area S2 and the rear area S3. In addition, in the absorbent article without the wing portion 25, at the position where the length of the absorbent article 1 in the front-back direction (L) is longest, there is a region where the absorbent article 1 is divided into three parts in the front-back direction (L). Each of may constitute a front area (S1), a crotch area (S2), and a rear area (S3).

In addition, the outer portion in the present invention is a portion that occupies a certain range in the width direction (W) including the outer edge in the width direction (W), and the outer edge is a portion that occupies a certain range in the width direction (W). It is the denotation of .

In addition, the front end and the rear end in the present invention are parts that occupy a certain range in the anteroposterior direction (L) including the edge in the anteroposterior direction (L), and the front and rear edges are in the anteroposterior direction (L). It is the edge of . The outer end includes a front end and a rear end, and the outer edge includes a front end and a rear end. Additionally, the medial side is a side that includes the medial edge and extends along the anteroposterior direction. The outer edge is a side that includes the outer edge and extends along the anteroposterior direction. In addition, in this specification, the term “along the front-back direction (L)” means a direction having an angle of less than 45° with respect to the front-back direction (L), and the term “along the width direction (W)” means means a direction having an angle of less than 45° with respect to the width direction (W).

The absorbent article (1) has at least a topsheet (10), an absorbent core (30), and a backsheet (20). The top sheet 10 is a sheet that faces the wearer's skin. The surface sheet 10 is disposed toward the wearer's skin during use. The top sheet 10 may be made of non-woven fabric or woven fabric having fibers. The top sheet 10 may be composed of a liquid-permeable sheet. The top sheet 10 may be comprised of a single sheet, or may be comprised of a center sheet covering the center of the absorbent core 30 in the width direction W, and a side sheet overlapping the outer portion of the center sheet. The absorbent core 30 extends along the front-back direction L of the absorbent article 1. The absorbent core 30 has an absorbent material capable of absorbing moisture. Absorbent materials include pulp and superabsorbent polymer (SAP). The absorbent core 30 may be covered with a core wrap made of tissue or the like. The absorbent core 30 may be disposed in at least the crotch region S2 and the rear region S3, or may be disposed in the front region S1, the crotch region S2, and the rear region S3. During use, the backsheet 20 faces away from the wearer's skin and comes into contact with the worn article. The backsheet 20 is a liquid-impermeable sheet and is a member located on the most non-skin surface side of the absorbent article. The top sheet 10 and the back sheet 20 are arranged over the entire plane of the absorbent article 1. The back sheet 20 will be described in detail later.

The absorbent article 1 may be individually packaged with a packaging sheet 40 before use. More specifically, the packaging sheet 40 and the absorbent article 1 are folded together in a state in which the absorbent article 1 is placed on the packaging sheet 40 (state shown in FIGS. 1 and 2), thereby packaging. The absorbent article 1 may be enclosed by the sheet 40. The packaging sheet may be made of existing materials such as films, non-woven fabrics, and woven fabrics. Fig. 5 shows the absorbent article 1 in a folded state with a plurality of fold marks as the starting point. FIG. 5(a) is a plan view in a folded state, and FIG. 5(b) is a cross-sectional view taken along line C-C shown in FIG. 5(a). The packaging sheet 40 may cover the non-skin surface side T2 of the back sheet 20 in the unfolded and folded states. The plurality of fold marks may be fold marks for folding the absorbent article 1 so that the skin surface side T1 faces each other, and may be along the front-back direction L or along the width direction W. The absorbent article 1 of this embodiment is folded starting from the first fold FW1 and the second fold FW2 along the width direction W. The first fold FW1 is provided later than the second fold FW2.

Next, the backsheet 20 will be described in detail. As shown in FIG. 4, the back sheet 20 includes a base portion 21 extending in a plane direction including the anteroposterior direction L and the width direction W, and a non-skin surface side from the base portion 21 ( It protrudes toward T2) and has a hook portion 22 for fastening to a worn article. The hook portion 22 is made of the same material and member as the base portion 21, and is formed continuously with the base portion 21. The base portion 21 is a layer with a predetermined thickness, and the thickness may be constant. The base portion 21 covers the non-skin surface side (T2) of the absorbent core 30 or the non-skin surface side (T2) of the core wrap. The hook portion 22 may have a shaft portion 221 extending in the thickness direction T from the base portion 21 and an umbrella portion 222 wider than the shaft portion 221 in the planar direction. . The umbrella portion 222 is wider than the shaft portion 221 in the planar direction and is configured to be caught by a wearing article or the top sheet 10. The total thickness of the backsheet 20 may be 30 μm to 100 μm, and the height of the hook portion 22 may be 10 μm to 30 μm.

According to this configuration, the absorbent article 1 can be hung and fixed to a wearing article via the hook portion 22 protruding toward the non-skin surface side T2 of the base portion 21. When the absorbent article 1 is worn, various forces are applied to the absorbent article 1 due to movement of the legs, etc. At this time, since the hook portion 22 is the same member as the base portion 21 and the hook portion 22 is formed continuously with the base portion 21, the hook portion 22 and the base portion 21 are connected. It is difficult for parts with low rigidity to occur locally. Therefore, when various forces are applied to the absorbent article 1, the entire backsheet 20 receives the force, and local breakage of the hook portions 22 can be suppressed. By suppressing breakage of the hook portion 22, it becomes easier to maintain a latched state for the worn article. Additionally, when disposing of the absorbent article 1 after use, it is common to roll up the absorbent article 1 so that the skin surface side T1 to which excrement is attached is inside. When the absorbent article 1 is rolled up with the skin surface side T1 facing inward, the top sheet 10 is arranged to cover the non-skin surface side T2 of the back sheet 20. Since the back sheet 20 has a hook portion 22 protruding toward the non-skin surface side T2, the hook portion 22 is caught and fixed to the top sheet 10, so that the absorbent article 1 is rolled up. can be maintained. When discarding, the absorbent article 1 can be kept in a rounded state, and the absorbent article 1 can be disposed of cleanly using the hook portion 22. The absorbent article 1 needs to be continuously hung and fixed to a wearing article during use and to be peeled off from the wearing article after use. Therefore, it is desirable for the hook portion 22 to have both engaging strength for continuously hooking and fixing the worn article and peeling strength for easy peeling.

The hook portions 22 are arranged in plural numbers at intervals in the front-back direction (L), and are also arranged in plural numbers at intervals in the width direction (W). The height H22 of the plurality of hook portions 22 may be constant. Here, the concept that the height H22 of the hook portion 22 is constant includes being within ±15 μm of the height of any hook portion. That is, when the heights of the plurality of hook parts 22 are slightly different, and the difference between the height of the highest hook part 22 and the height of the lowest hook part 22 is 30㎛, the plurality of hook parts 22 ) is assumed to be constant. Additionally, the height H22 of the hook portion 22 is the height with respect to the base portion 21, as shown in FIG. 4 . In a configuration having hook portions 22 of different heights, an imbalance occurs in the force applied to the hook portions 22 due to the difference in height, and force is applied locally to some of the hook portions 22, causing the There is a risk that some of the hook portions 22 may break. However, since the height of the plurality of hook portions 22 is constant, the imbalance of force due to the difference in height is suppressed, and the entire back sheet 20 receives force, preventing local breakage of the hook portion 22. It can be suppressed.

The hook portion 22 may be disposed over the entire surface of the core arrangement region R30 that overlaps the absorbent core 30 in the thickness direction T. The core arrangement region R30 is an area where the absorbent core 30 is arranged in a plan view shown in FIG. 1 and the like, and is an area indicated by a diagonal line in FIG. 1 . Additionally, the base portion 21 is provided on the front surface of the backsheet 20, and the hook portions 22 are arranged at intervals. Therefore, the configuration in which the hook portion 22 is disposed over the entire core arrangement area R30 is not limited to the configuration in which the hook portion 22 is arranged so as to fill the entire surface of the core arrangement area R30. As in the present embodiment, it includes a configuration in which the hook portions 22 are disposed throughout the core arrangement area R30 at regular intervals. According to this configuration, the absorbent article 1 can be hung and fixed to a wearing article via the hook portion 22 over the entire surface of the core arrangement region R30. The entire area (core placement area) R30 where the absorbent core 30 for absorbing body fluids is placed becomes difficult to float from the worn article, preventing problems such as body fluids unintentionally adhering to the body or leaking. You can.

The hook portion 22 may be disposed on the flap portion. The flap portion is a portion disposed outside the core arrangement area R30 in the width direction W and bulging outward in the width direction W. The wing portion 25 of this embodiment constitutes a flap portion. Additionally, the flap portion may include a hip flap portion that bulges outward in the width direction in the rear region S3. The flap portion does not have the absorbent core 30 disposed thereon, has lower rigidity compared to the core disposition region R30, and may be twisted when worn. However, since the hook portion 22 is disposed on the flap portion, the flap portion can also be hooked and fixed to a worn article via the hook portion, thereby preventing the flap portion from twisting when worn.

The hook portion 22 may be disposed over the entire surface of the backsheet 20. Here, the configuration in which the hook portion 22 is disposed over the entire front surface of the back sheet 20 is not limited to a configuration in which the hook portion 22 is disposed so as to fill the entire front surface of the back sheet 20, and is not limited to a configuration in which the hook portion 22 is disposed so as to fill the entire front surface of the back sheet 20. It includes a configuration in which hook portions 22 are arranged throughout the back sheet 20 at regular intervals as shown in the shape. According to this configuration, the backsheet 20 is disposed on the front surface of the absorbent article 1, and the hook portion 22 is disposed over the entire surface of the backsheet 20, so that the hook portion 22 The front of the absorbent article 1 can be hooked and fixed to a wearing article.

The thickness T21 of the base portion 21 may be thicker than the height H22 of the hook portion 22. Since the thickness T21 of the base portion 21 is thicker than that of the hook portion 22, the ratio contributing to the rigidity of the backsheet 20 tends to be higher in the base portion 21 than in the hook portion 22. The base portion 21 extends in a planar direction over the entire backsheet 20. In contrast, the hook portions 22 are arranged at intervals in the planar direction. Therefore, a difference in rigidity occurs in the back sheet 20 depending on the presence or absence of the hook portion 22. However, since the ratio contributing to the rigidity of the backsheet 20 is higher in the base portion 21 than in the hook portion 22, the difference in rigidity due to the presence or absence of the hook portion 22 affects the rigidity of the entire backsheet 20. This makes it difficult to contribute, and imbalance in the rigidity of the back sheet 20 can be suppressed. Accordingly, by suppressing the imbalance in the rigidity of the backsheet 20, local breakage of the hook portion 22 can be suppressed, and it becomes easy to maintain the latching state for the worn article.

At least a portion of the back sheet 20 may be covered by the packaging sheet 40 in the folded state shown in FIG. 5 . The hook portion 22 may be engaged with the packaging sheet 40. The packaging sheet 40 covers the hook portion 22 before use and protects the hook portion 22. The problem of the hook portion 22 being unintentionally caught on the surface sheet 10 or the like before use of the absorbent article 1 can be suppressed. Additionally, compared to a configuration in which the absorbent article 1 is hung and fixed to a wearing article using a conventional adhesive, the adhesive and a release sheet to protect the adhesive are unnecessary, and the number of parts can be reduced.

In the deployed state, the backsheet 20 may have a uncovered region NR that is not covered by the packaging sheet 40 in the deployed state. The uncovered area NR is a partial area of the back sheet 20 and is an area that is not covered by the packaging sheet 40 in the unfolded state shown in FIG. 2. In Fig. 2, a diagonal line is drawn on the uncovered area NR. In the deployed state, a portion of the backsheet 20 is covered by the packaging sheet 40, and another portion of the backsheet 20 (uncovered area NR) is not covered by the backsheet 20. not. Additionally, the unfolded state is a state in which the absorbent article 1 is not folded starting from a fold, and in the form having a plurality of folds, it is a state in which the absorbent article 1 is not folded starting from any of the folds. As shown in FIG. 5(b), in the folded state, the hook portion 22 in the uncovered region NR may be disposed opposite to the topsheet 10 or may be hooked to the topsheet 10. do. In the folded state, the hook portions 22 in the uncovered region NR can be covered by the top sheet 10, and the hook portions 22 other than the uncovered region NR can be covered with the back sheet 20. It can be covered. The problem of the hook portion 22 being unintentionally caught on a sheet, etc. before use of the absorbent article 1 can be suppressed. Additionally, in this embodiment, the folded state is maintained by means of a sealing tape 45 that secures the end portion of the packaging sheet 40 in the folded state. However, in the folded state, the hook portion 22 of the back sheet 20 is caught and fixed to the top sheet 10, so that the folded state can be maintained without using the sealing tape 45 to join the packaging sheets 40 to each other. It is also possible to maintain it.

Additionally, in a modified example, the back sheet 20 may be covered with the packaging sheet 40 over the entire surface in the unfolded state. Since the front of the back sheet 20 is covered with the packaging sheet 40, the entire hook portion 22 before use can be covered with the packaging sheet 40, thereby protecting the hook portion 22. there is. The problem of the hook portion 22 being unintentionally caught on the surface sheet 10 or the like before use of the absorbent article 1 can be suppressed.

Although the present invention has been described in detail using the above-described embodiments, it is clear 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 in modified and altered forms without departing from the spirit and scope of the present invention defined by the description of the claims.
