Description

Absorbent article {ABSORBENT ARTICLE}

The present invention relates to an absorbent article having an adhesive portion for fixing to clothing on the back sheet side, such as a sanitary napkin, panty liner, breast milk pad, adult incontinence pad, fecal pad or sweat absorbent sheet.

An absorbent article, such as a sanitary napkin or panty liner, is attached to the inside of a wearable article that is worn on a wearer in use. In general, an absorbent article attached to the inside of a wearing article has an adhesive portion for preventing the absorbent article from shifting with respect to the wearing article. The adhesive portion is formed on the surface of the absorbent article opposite to the skin surface side (the side facing the wearer's skin). In such an absorbent article, when the wearable article removed from the wearable article after use is rolled up in the longitudinal direction, the adhesive portion comes into contact with the skin surface of the absorbent article. However, since body fluid adheres to the skin surface (topsheet) of the absorbent article after use, the body fluid inhibits bonding between the adhesive portion and the topsheet, and the absorbent article cannot be rolled up compactly in some cases.

Patent Document 1 discloses a sanitary napkin provided with a post-treatment tape portion. This sanitary napkin has a napkin absorbent side facing the wearer's skin when in use, and a napkin guard side facing the undergarment when in use. An adhesive tape for adhering the sanitary napkin to the underwear is formed on the napkin guard surface. Moreover, the post-processing tape part is formed in the part which protruded outward from the napkin absorption surface in the longitudinal direction of a napkin. Further, the post-treatment tape portion is oriented in the same direction as the napkin absorbent surface, that is, in the direction of the wearer's skin.

Patent Document 1: Japanese Utility Application Publication No. Hei 04-35422

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

An absorbent article according to one aspect is an absorbent article having a front-rear direction, a width direction perpendicular to the front-back direction, a back sheet facing to the side opposite to the wearer's skin, and an adhesive portion formed on the non-skin side of the back sheet, , on the non-skin surface side of the back sheet, further comprising a tape member disposed inside the outer edge of the absorbent article, wherein the tape member is configured to be extendable outward from the outer edge of the absorbent article.

In this aspect, the user can extend the tape member outward from the outer edge of the absorbent article after turning the absorbent article in the front-back direction after use. During use, since the tape member is disposed inside the outer edge of the absorbent article on the non-skin surface side of the backsheet, body fluids such as menstrual blood do not adhere to the tape member. After use of the absorbent article, the user can keep the absorbent article in a rounded state by attaching the tape member extended outward to an adhesive portion formed on a separate portion of the back sheet. Here, since bodily fluids such as menstrual blood do not adhere to the tape member, a decrease in bonding strength between the tape member and the adhesive portion can be prevented, thereby making it easy to keep the absorbent article in a small rounded state.

Moreover, since an absorbent article turns inside the surface to which bodily fluids, such as menstrual blood, adhered, and is dried, bodily fluid does not adhere to the surface of the dried absorbent article. Thereby, the user can cleanly process the absorbent article after use.

In addition, the user can place the absorbent article after use on a small space near one end in a small rounded state. Therefore, the user can attach a new absorbent article to a wearing article such as underwear, and after wearing the underwear or clothes, discard the used absorbent article in a trash can or the like. In addition, in a situation where there is no waste bin for disposing of the absorbent article in the vicinity, the user may put the absorbent article in a small round shape and take it with him.

In addition, during use of the absorbent article, the tape member is formed on the non-skin surface side of the back sheet and does not extend outward from the outer edge of the absorbent article, so that the tape member does not directly contact the wearer's skin. Therefore, discomfort and discomfort during use can be reduced.

According to a preferred aspect, the absorbent article has at least two fold lines extending in the width direction, and the tape member is formed on the front side of the frontmost fold line among the fold lines, or on the rear side of the rearmost fold line. has been

Depending on the user, when rolling up the absorbent article after use, the absorbent article may be started to roll along the fold line along the width direction. In this case, the area in front of or behind the rearmost fold of the at least two fold lines of the at least two fold lines is exposed on the surface of the rolled absorbent article and may be located on the terminal side in the winding direction. Since the tape member is disposed at a location exposed at the end side in the winding direction, the user can easily recognize the tape member and easily fix the tape member to the adhesive part while the absorbent article is rolled up. there is.

According to one preferable aspect, the said tape member is formed in the range of the length of 1/3 of the length of the said absorbent article in the said front-back direction from the edge of the said absorbent article in the said front-back direction.

When the absorbent article is rolled loosely after use while taking into account that the body fluid adhering to the skin surface of the absorbent article is covered, the user may roll the absorbent article so that approximately 1/3 of the area of the absorbent article is disposed on the inside ( such as Fold in Three or Fold in Four). In this case, from the edge of the absorbent article in the front-back direction, the length of 1/3 of the length of the absorbent article in the front-back direction is the longitudinal end side of the winding direction among the areas exposed to the surface of the rounded absorbent article. becomes the area of Since the tape member is disposed at a position exposed on the terminal side in this winding direction, the user can easily recognize the tape member and can easily fix the tape member in a rolled up state of the absorbent article.

According to one preferable aspect, the said tape member is formed in the range of the length of 15% of the length of the said absorbent article in the said front-back direction from the edge of the said absorbent article in the said front-back direction.

When the absorbent article after use is rolled taut while taking into account that the body fluid adhering to the skin surface of the absorbent article is covered, from the edge of the absorbent article in the front-rear direction to 10% of the length of the absorbent article in the front-rear direction The range of about 15% of the length becomes the area|region on the terminal side of the winding-up direction among the area|regions exposed to the surface of the rounded absorbent article. Since the tape member is disposed at a position exposed on the terminal side in this winding direction, the user can easily recognize the tape member and can easily fix the tape member in a rolled up state of the absorbent article.

According to one preferable aspect, the said tape member is comprised so that it can extend in the front side from the front edge of the said absorbent article, or rearward from the rear edge of the said absorbent article.

A user usually starts rolling up the absorbent article after use in the front-back direction from the front side or the back side. When the tape member is configured to be able to extend on the front side of the front edge of the absorbent article or on the rear side of the rear edge of the absorbent article, the user can attach the tape member by extending the tape member along the winding direction.

Moreover, about 80% of users start rolling up the absorbent article after use from the front side. Therefore, it is more preferable that the tape member is comprised so that it can extend rearward rather than the rear edge of an absorbent article.

According to one preferable aspect, the said adhesive part is formed on the imaginary line which extended the said tape member in the said front-back direction.

Accordingly, when the tape member is extended in front of the front edge of the absorbent article or rearward than the rear edge of the absorbent article, and the tape member is straightly poured onto the rolled absorbent article, the adhesive portion is attached to the tape member. Accordingly, the user can easily hold the absorbent article in a rounded state without pulling the tape member obliquely toward the position of the adhesive portion.

According to a preferred aspect, a plurality of the adhesive portions are formed at intervals in the width direction, and the width of the tape member in the width direction is larger than the interval between the adhesion portions in the width direction.

Accordingly, it is possible to prevent the case where the adhesive portion does not exist at the end of the tape member taken out by the user. Accordingly, the user can easily attach the tape member to the adhesive portion.

According to a preferred aspect, the absorbent article has a hip flap that bulges outward in the width direction behind a region facing the excretion port of the wearer, the tape member is formed on the hip flap, the tape member comprising: It is comprised so that it can extend outward from the outer edge of the said hip flap in the said width direction.

The hip flap is located at the back of the absorbent article. Here, about 80% of users begin to roll the absorbent article after use from the front side. Accordingly, the tape member is exposed on the surface of the rounded absorbent article. The user can maintain the absorbent article in a rounded state by extending the tape member outward in the width direction from the hip flap and attaching the tape member to an adhesive portion formed at a separate position of the back sheet.

Further, since the hip flap is a bulge in the width direction, when the tape member is attached to the adhesive portion, the hip flap covers the side surface of the rolled up absorbent article. Thereby, leakage of the body fluid from the side surface of the rolled absorbent article can be prevented. Further, since the hip flap covers the side surface of the rolled absorbent article, the body fluid adhering to the skin surface side of the absorbent article can be covered and covered, and the feeling of cleanliness can be improved.

According to one preferred aspect, the adhesive portions are formed at intervals in the front-back direction, and the width of the tape member in the front-back direction is larger than the interval between the adhesive portions in the front-back direction.

Accordingly, it is possible to prevent the case where the adhesive portion does not exist at the end of the tape member taken out by the user. Accordingly, the user can easily attach the tape member to the adhesive portion.

According to a preferred aspect, at least a portion of the adhesive portion is formed on the front side of the tape member.

Since the adhesive part exists on the front side of the tape member, when the tape member extended outward in the width direction from the hip flap is attached to the adhesive part existing at a separate position of the back sheet, the absorbent article is rounded. can be maintained as

According to one preferred aspect, at least a portion of the adhesive portion is 2/ the length of the absorbent article in the front-rear direction from the edge closer to the tape member among both edges of the absorbent article in the front-rear direction. It is formed in the range of the length of 3.

When the absorbent article is rolled loosely after use, the user may roll the absorbent article so that approximately 1/3 of the area of the absorbent article is disposed inside (a state such as three-fold or four-fold). In this case, from the edge of the absorbent article in the front-back direction, the range of the length of 2/3 of the length of the absorbent article in the front-back direction is exposed on the surface of the rounded absorbent article. Since the adhesive portion is disposed in this exposed region, the user can easily attach the tape member to the adhesive portion.

According to a preferred aspect, at least a portion of the adhesive portion is 4/ the length of the absorbent article in the front-rear direction from the edge closer to the tape member among both edges of the absorbent article in the front-rear direction. It is formed in the range of the length of 5.

When the absorbent article after use is rolled taut, from the edge of the absorbent article in the front-back direction, the range of the length of about 20% to 30% of the length of the absorbent article in the front-back direction is on the surface of the rounded absorbent article. are exposed Since the adhesive portion is disposed in this exposed region, the user can easily attach the tape member to the adhesive portion.

According to one preferred aspect, the tape member has a fixing portion fixed to the non-skin surface of the absorbent article, and the tip of the tape member in the extension direction is directed to the opposite side to the fixing portion.

When the tape member extends outside the outer edge of the absorbent article, a force is applied to the fixing portion of the tape member only in the extension direction. Accordingly, since the force applied to the fixing portion can be made as small as possible, the fixing strength of the tape member can be maintained.

According to a preferred aspect, at least one of a surface of the tape member in contact with the back sheet and a surface of the back sheet in contact with the tape member is subjected to an antistatic treatment.

Thereby, it is possible to suppress the tape member from sticking to the back sheet by static electricity. Therefore, when the absorbent article is rolled up, the tape member more easily floats off the back sheet, and the user can more easily pick up the tape member and operate it.

According to a preferred aspect, the absorbent article has an absorbent body formed on the skin surface side of the back sheet, the tape member has a fixing portion fixed to the non-skin surface of the absorbent article, and at least a part of the fixing portion comprises: It overlaps with the said absorber in the thickness direction.

The region in which the absorber exists is a region with particularly high rigidity in the absorbent article. Since the fixing part of the tape member overlaps the absorbent body in the thickness direction, when the absorbent article is rolled up, the fixing part of the tape member located in the region with high rigidity is reliably curved together with the absorbent article. In this way, when the fixing portion of the tape member is reliably curved, the free end of the tape member is more easily floated from the back sheet. Therefore, the user can pick up and operate the tape member more easily.

According to a preferred aspect, the absorbent article has an absorbent body formed on the skin surface side of the back sheet, and the tape member overlaps the embossed body formed on the absorbent body or a low unit weight region formed on the absorbent body in the thickness direction.

When the tape member overlaps the embossed body formed on the absorber or the low unit weight region formed on the absorber in the thickness direction, a gap is likely to occur between the tape member and the back sheet (absorbent body). Therefore, when the absorbent article is rolled up, the tape member more easily floats off the back sheet, and the user can more easily pick up the tape member and operate it.

According to a preferred aspect, in the absorbent article, the tape member has a fixing portion fixed to the non-skin surface of the absorbent article, and at least a region of the tape member excluding the fixing portion does not overlap the adhesive portion. formed in position.

Thereby, when the absorbent article is rolled up, the tape member tends to float from the back sheet. Accordingly, the user can more easily pick up and operate the non-fixed portion of the tape member.

Hereinafter, with reference to drawings, the absorbent article which concerns on embodiment is demonstrated. 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 fecal pad or a sweat absorbent sheet. In particular, the absorbent article may be an article used by being attached to the inside of a wear article such as a user's underwear.

BRIEF DESCRIPTION OF THE DRAWINGS It is a top view of the absorbent article which concerns on 1st Embodiment seen from the skin surface side. It is a top view of the absorbent article which concerns on 1st Embodiment seen from the non-skin surface side. 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 away from the wearer's skin during use.

The absorbent article has a front-back direction (L) and a width direction (W). The front-back direction L is a direction extending from the front side (ventral side) to the rear side (back side) of the wearer, 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 absorbent article 10 includes a topsheet 20 , a backsheet 22 , and an absorbent body 30 between the topsheet 20 and the backsheet 22 . The topsheet 20 faces the wearer's skin side during use. The backsheet 22 faces away from the wearer's skin during use. The absorber 30 is extended along the front-back direction L of an absorbent article.

The absorbent article 10 may have the wings 40 and the hip flaps 50 . The wing 40 is folded back toward the non-skin surface side of the crotch portion of the wearable article in use. The hip flap 50 is a part which bulged in the width direction W behind the wing 40. The hip flap 50 is a part protruding outward from the outer edge of the absorber 30 in the width direction W. As shown in FIG.

The absorbent article 10 has an excretory opening facing region S1 that faces the wearer's excretory opening (eg, vaginal opening) during use. The excretion port facing region S1 is a region disposed between the wearer's crotch, that is, between the wearer's legs, and corresponds to the region where the absorbent body 30 exists. Further, in the absorbent article 10 having the wings 40 , the excretion port facing region S1 is between the wings 40 and corresponds to the region where 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 surface 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 wearing article is formed. The adhesive part includes a main body adhesive part 70 , a wing adhesive part 42 , and a flap adhesive part 52 .

The main body adhesive part 70 is formed in the area|region which overlaps with the absorber 30 in the thickness direction of an absorbent article. It is preferable that the main body adhesive portion 70 extends continuously or intermittently from at least the excretion port facing region S1 to the rear of the absorbent article 10 . The main body adhesive part 70 may extend in the front-back direction L, and may be formed in multiple numbers at intervals in the width direction W.

The antistatic treatment may be, for example, a surface treatment such as corona treatment or embossing. The tape member 60 may stick to the back sheet 22 by static electricity. By the antistatic treatment, it is possible to suppress the tape member 60 from sticking to the back sheet 22 . Therefore, when the absorbent article 10 is rolled up, the tape member 60 is more likely to float from the back sheet 22, and the user can pick up the tape member 60 more easily and operate it.

It is preferable that at least a part of the fixing part 62 of the tape member 60 overlaps with the absorber 30 in the thickness direction. The region where the absorber 30 exists is a region with particularly high rigidity in the absorbent article 10 . Since the fixing part 62 of the tape member 60 overlaps with the absorbent body 30 in the thickness direction, when the absorbent article 10 is rolled up, the fixing part of the tape member 60 located in the area|region with high rigidity. (62) is curved securely together with the absorbent article (10). In this way, since the fixing portion 62 of the tape member 60 is reliably curved, the free end of the tape member 60 is more likely to float from the back sheet 22 . Therefore, the user can pick up and operate the tape member 60 more easily.

It is preferable that at least the region excluding the fixing portion 62 of the tape member 60 is formed at a position that does not overlap the adhesive portions 42 , 52 , and 70 . Accordingly, when the absorbent article 10 is rolled up, the tape member 60 tends to float from the back sheet 22 . Therefore, the user can pick up and operate the tape member 60 more easily.

The absorber 30 may be provided with an embossing (compression portion) of a predetermined pattern. In addition, the absorber 30 may have a low unit weight region having a unit weight lower than the unit weight of the surrounding absorber 30 . In this case, it is preferable that the tape member 60 overlaps in the thickness direction with the embossing formed on the absorber 30 or the low unit weight region formed on the absorber 30 . When the tape member 60 overlaps the embossed body formed on the absorbent body 30 or the low unit weight region formed on the absorbent body 30 in the thickness direction, the tape member 60 and the back sheet 22 (absorbent body 30) ), a gap is likely to form between them. Therefore, when the absorbent article 10 is rolled up, the tape member 60 is more likely to float from the back sheet 22, and the user can pick up the tape member 60 more easily and operate it.

It is a perspective view of the absorbent article which concerns on 3rd Embodiment of the state rolled in the front-back direction. 7 : is a figure of the absorbent article which concerns on 3rd Embodiment of the state fixed with the tape member.

In addition, about the structure similar to 1st Embodiment, the same code|symbol is attached|subjected and the description may be abbreviate|omitted. Hereinafter, a configuration different from the first embodiment will be described in detail.

In the third embodiment, the position of the tape member 60 is different from that in the first embodiment. In the third embodiment, the tape member 60 is formed on the hip flap 50 . The tape member 60 is comprised so that it can extend outward from the outer edge of the hip flap 50 in the width direction W. As shown in FIG.

The hip flap 50 is located at the back of the absorbent article 10 . Here, about 80% of users begin to roll the absorbent article 10 after use from the front side. Accordingly, the tape member 60 is exposed on the surface of the rounded absorbent article 10 . In addition, in FIG. 6, the state which pulled the tape member 60 is shown. The user extends the tape member 60 outward in the width direction W from the hip flap 50 (see FIG. 6 ), and the tape member 60 on the adhesive portion formed at a separate position of the back sheet 22 . By attaching the absorbent article, it is possible to keep the absorbent article in a rounded state (see Fig. 7).

In addition, since the hip flap 50 is a bulge in the width direction W, when the tape member 60 is attached to the adhesive portion, the hip flap 50 covers the side surface of the rolled absorbent article 10 . (See Fig. 7). Thereby, leakage of the body fluid from the side surface of the rolled absorbent article 10 can be prevented. In addition, since the hip flap 50 covers the side surface of the rolled absorbent article 10, the body fluid adhering to the skin surface side of the absorbent article 10 can be covered and covered, thereby improving the feeling of cleanliness.

In the third embodiment, the main body adhesive portions 70 may be formed at intervals in the front-back direction L. In this case, it is preferable that the width W1 of the tape member 60 in the front-back direction L is larger than the space|interval W3 of the main body adhesive parts 70 comrades in the front-back direction L. Accordingly, it is possible to prevent a case in which the main body adhesive part 70 does not exist at the end of the user withdrawing the tape member 60 . Accordingly, the user can easily attach the tape member 60 to the main body adhesive portion 70 .

Moreover, when there exist two or more intervals of the main body adhesive part 70 in the front-back direction L, the width W1 of the tape member 60 is the largest among the some space|interval in the front-back direction L. It is more preferable to be larger than the interval.

It is preferable that at least a part of the main body adhesive part 70 is formed in front of the tape member 60. As shown in FIG. Since the main body adhesive portion 70 is present on the front side of the tape member 60 , the user can attach the tape member 60 extending outward in the width direction W from the hip flap 50 to the back sheet 22 . When the absorbent article 10 is attached to the main body adhesive portion 70 existing at a separate position (a separate position in the front-rear direction L), the absorbent article 10 can be maintained in a rounded state.
