Description

Absorbent article

The present invention relates to an absorbent article having an adhesive portion fixed to the backsheet side such as a sanitary napkin, a panty liner, a breast pad, an adult incontinence pad, a feces pad or a sweat absorbent sheet.

An absorbent article such as a sanitary napkin or panty liner is affixed to the inside of a wear article to be worn on the wearer at the time of use. Generally, the absorbent article attached to the inside of the wearing article has an adhesive portion for preventing the absorbent article from being displaced with respect to the wearing article. This adhesive portion is formed on the surface opposite to the skin surface side (the side facing the wearer's skin) of the absorbent article. In such an absorbent article, when the wearing article detached from the wearing article after use is placed in the longitudinal direction, the adhesive section touches the skin surface of the absorbent article. However, since the body fluid adheres to the skin surface (topsheet) of the absorbent article after use, the body fluid hinders the adhesion between the adhesive portion and the topsheet, and the absorbent article can not be compacted in some cases.

Patent Document 1 discloses a sanitary napkin having a post-treatment tape portion. The sanitary napkin has a napkin absorbing face facing the wearer's skin at the time of use and a napkin guard face facing the undergarment at the time of use. An adhesive tape for bonding the sanitary napkin to the undergarment is formed on the napkin guard surface. Further, the post-processing tape portion is formed at a portion protruding outward from the napkin absorbing surface in the longitudinal direction of the napkin. Further, the post-treatment tape portion is directed in the same direction as the napkin absorbing surface, i.e., in the direction of the skin of the wearer.

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

In the sanitary napkin described in Patent Document 1, the post-treatment tape portion is directed in the same direction as the napkin absorbing surface. This post-treatment tape portion is in contact with the wearer's skin during use of the sanitary napkin. Therefore, it gives a wearer a sense of discomfort or discomfort.

Accordingly, there is a demand for an absorbent article having an adhesive portion on the non-skin surface side that can be kept in a rounded state after use and capable of reducing uncomfortable feeling and discomfort during use.

The absorbent article related to one aspect of the present invention is an absorbent article having a back sheet oriented in a front-back direction, a width direction orthogonal to the front-back direction, a side opposite to the wearer's skin, and an adhesive portion formed on the non- And a tape member disposed on the non-skin surface side of the backsheet and disposed inside the outer edge of the absorbent article, wherein the tape member is configured to extend outward beyond the outer edge of the absorbent article.

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

The absorbent article related to one aspect of the present invention is an absorbent article having a back sheet oriented in a front-back direction, a width direction orthogonal to the front-back direction, a side opposite to the wearer's skin, and an adhesive portion formed on the non- And a tape member disposed on the non-skin surface side of the backsheet and disposed inside the outer edge of the absorbent article, wherein the tape member is configured to extend outward beyond the outer edge of the absorbent article.

In this aspect, the user can extend the tape member outward beyond the outer edge of the absorbent article, only after the user has used the absorbent article in the anteroposterior direction. During use, since the tape member is disposed inside the outer edge of the absorbent article at the non-skin surface side of the backsheet, body fluids such as menstrual blood do not adhere to the tape member. The user can keep the absorbent article in a rounded state by attaching the tape member extended outwardly to the adhesive portion formed on another portion of the backsheet after use of the absorbent article. Here, since the body fluid such as menstrual blood does not adhere to the tape member, the lowering of the bonding force between the tape member and the adhesive portion can be prevented, and the absorbent article can be easily held in a small rounded state.

Further, since the absorbent article is dried with the surface to which body fluids such as menstrual blood are attached, the body fluids are not attached to the surface of the dried absorbent article. Accordingly, the user can clean the used absorbent article cleanly.

In addition, the user can leave the used absorbent article in a small, rounded state on a small space near the end. Accordingly, the user can attach the new absorbent article to the wearing article such as underwear, and after wearing the undergarment or clothes, the user can dispose the used absorbent article in the trash can or the like. Further, under a situation where a garbage can is not near to dispose of the absorbent article, the user may take a small, round absorbent article in the bag.

Further, during use of the absorbent article, the tape member is formed on the non-skin surface side of the backsheet and does not extend outward beyond the outer edge of the absorbent article, so that the tape member does not directly touch the skin of the wearer. Therefore, it is possible to reduce discomfort or discomfort during use.

According to a preferred aspect of the present invention, the absorbent article has at least two folding lines extending along the width direction, and the tape member is formed on the front side of the frontmost folding line of the folding line, .

Depending on the user, there is a case where the absorbent article starts using the absorbent article along the folding line along the width direction. In this case, the front side of the frontmost folding line of at least two folding lines, or the rearward side of the folding line from the rearmost side, may be exposed on the surface of the dried absorbent article and may be located on the end side in the winding direction. The tape member can be easily recognized by the user and the tape member can be easily fixed to the adhesive portion in a state in which the absorbent article is rounded easily since the tape member is disposed at the exposed position on the end side in the take- have.

According to a preferred embodiment, the tape member is formed within the range of the length of 1/3 of the length of the absorbent article in the longitudinal direction from the edge of the absorbent article in the longitudinal direction.

In the case of loosening the absorbent article after use, taking into consideration that the body fluid adhered to the skin surface of the absorbent article is covered, the user sometimes wears the absorbent article so that approximately one-third of the area of the absorbent article is disposed on the inner side Folded into a set or folded into a net). In this case, the range of the length of 1/3 of the length of the absorbent article in the anteroposterior direction from the edge of the absorbent article in the anteroposterior direction, . Since the tape member is disposed at a position exposed from the end side in the winding direction, the user can easily recognize the tape member, and can easily fix the tape member in a state in which the absorbent article is rounded.

According to a preferred embodiment, the tape member is formed within a range of 15% of the length of the absorbent article in the anteroposterior direction from the edge of the absorbent article in the anteroposterior direction.

The length of the absorbent article in the forward and backward directions from the edge of the absorbent article in the forward and backward directions is preferably 10% to 10% of the length of the absorbent article in the forward and backward directions, when considering the fact that the body fluid adhered to the skin surface of the absorbent article is covered, A length of about 15% is a region of the region exposed on the surface of the rounded absorbent article and a region on the end side in the winding direction. Since the tape member is disposed at a position exposed from the end side in the winding direction, the user can easily recognize the tape member, and can easily fix the tape member in a state in which the absorbent article is rounded.

According to a preferred embodiment, the tape member is configured to be able to extend forward of the front edge of the absorbent article or rearward of the rear edge of the absorbent article.

Normally, the user starts to use the absorbent article after use from the front side or back side in the back and forth direction. The tape member is configured to extend forward from the front edge of the absorbent article or backward beyond the rear edge of the absorbent article so that the user can extend the tape member along the winding direction and attach the tape member.

In addition, a user of about 80% starts to use the absorbent article after use from the front side. Therefore, it is more preferable that the tape member is configured to be able to extend rearward beyond the rear edge of the absorbent article.

According to a preferred embodiment, the adhesive portion is formed on an imaginary line extending in the longitudinal direction of the tape member.

Thus, the tape member is attached to the tape member by extending the tape member forward of the front edge of the absorbent article or rearward of the rear edge of the absorbent article, and allowing the tape member to follow the dried absorbent article straightly. Thus, the user can easily keep the absorbent article in a rounded state without tensioning the tape member obliquely toward the position of the adhesive portion.

According to a preferred embodiment, the plurality of 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 gap between the adhesive portions in the width direction.

Thus, it is possible to prevent the case where the user does not have the adhesive portion at the end where the tape member is drawn out. Therefore, the user can easily attach the tape member to the adhesive portion.

According to a preferred aspect of the present invention, the absorbent article has a hip flap bulged outward in the width direction from the rear than the area facing the excretion of the wearer, and the tape member is formed on the hip flap, And extend outside the outer edge of the hip flap in the width direction.

The hip flap is located behind the absorbent article. Here, about 80% of users start to use the absorbent article after use from the front side. Thus, the tape member is exposed on the surface of the rounded absorbent article. The user can keep 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 the adhesive portion formed at a different position of the back sheet.

Further, since the hip flap is bulged in the width direction, when the tape member is attached to the adhesive portion, the hip flap covers the side surface of the dried absorbent article. Thus, leakage of the body fluids from the side of the dried absorbent article can be prevented. Further, since the hip flap covers the side surface of the dried absorbent article, the body fluids attached to the skin surface side of the absorbent article can be covered and the cleanliness can be improved.

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

Thus, it is possible to prevent the case where the user does not have the adhesive portion at the end where the tape member is drawn out. Therefore, the user can easily attach the tape member to the adhesive portion.

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

Since the adhesive portion exists on the front side of the tape member, when the user attaches the tape member extended outward in the width direction from the hip flap to the adhesive portion existing at a different position of the backsheet, .

According to a preferred embodiment, at least a part of the adhesive portion extends from an edge of one of the opposite edges of the absorbent article toward the tape member in the anteroposterior direction, 3 < / RTI >

In the case of loosening the used absorbent article, the user sometimes wears the absorbent article so that approximately one third of the area of the absorbent article is located inside (three folded or folded into a net). In this case, a range of 2/3 of the length of the absorbent article in the anteroposterior direction from the edge of the absorbent article in the anteroposterior direction is exposed on the surface of the rounded absorbent article. The user can easily attach the tape member to the adhesive portion.

According to a preferred embodiment, at least a part of the adhesive portion is formed to extend from the edge of one of the opposite edges of the absorbent article in the front-back direction to the tape member, 5 < / RTI >

When the used absorbent article is tightened, a range of a length of 20% to 30% of the length of the absorbent article in the anteroposterior direction from the edge of the absorbent article in the anteroposterior direction is applied to the surface of the rounded absorbent article Exposed. The user can easily attach the tape member to the adhesive portion.

According to a preferred embodiment, the tape member has a fixing portion fixed to the non-skin surface of the absorbent article, and the leading end portion of the tape member in the extending direction is directed toward the side opposite to the fixing portion.

When the tape member is extended to the outside of the outer edge of the absorbent article, a force acts on the fixed portion of the tape member only in the extending direction. As a result, the force applied to the fixing portion can be made as small as possible, so that the fixing strength of the tape member can be maintained.

According to a preferred embodiment, at least one of the surface of the tape member contacting the backsheet and the surface of the backsheet contacting the tape member is subjected to antistatic treatment.

Thus, it is possible to prevent the tape member from sticking to the backsheet by static electricity. Therefore, when the absorbent article is put on the wearer's body, the tape member is more likely to float from the back sheet, and the user can more easily pick and operate the tape member.

According to a preferred aspect of the present invention, the absorbent article has an absorbent body formed on the skin surface side of the backsheet, the tape member has a fixing portion fixed to the non-skin surface of the absorbent article, And is overlapped with the absorbent body in the thickness direction.

The region where the absorber exists is a region having particularly high rigidity among the absorbent articles. Since the fixing portion of the tape member is overlapped with the absorbent body in the thickness direction, when the absorbent article is put in place, the fixing portion of the tape member located in the region of high rigidity is reliably curved together with the absorbent article. As described above, the free end of the tape member is more likely to float from the backsheet because the fastening portion of the tape member is reliably bent. Thus, the user can more easily pick and operate the tape member.

According to a preferred embodiment, the absorbent article has an absorbent body formed on the skin surface side of the backsheet, and the tape member is overlapped with the embossed body formed on the absorbent body or the low unit weight region formed on the absorbent body in the thickness direction.

If the tape member is overlapped with the low-unit weight region formed in the emboss or absorber formed on the absorber in the thickness direction, a gap is likely to be generated between the tape member and the back sheet (absorber). Therefore, when the absorbent article is put on the wearer's body, the tape member is more likely to float from the back sheet, and the user can more easily pick and operate the tape member.

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 a region of the tape member other than at least the fixing portion is not overlapped with the adhesive portion .

As a result, when the absorbent article is put on the tape, the tape member is liable to float from the backsheet. Thus, the user can more easily pick and operate the non-fixed portion of the tape member.

Hereinafter, an absorbent article related to the 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 pad, an adult incontinence pad, a feces pad or a sweat absorbent sheet. In particular, the absorbent article may be an article attached to the inside of a wearable article such as a user's undergarment.

The " non-skin surface side " corresponds to the side which is opposite to the skin of the wearer during use.

The absorbent article has an anteroposterior direction L and a width direction W. [ The back-and-forth direction L is a direction extending from the front side (rear side) to the rear side (back side) of the wearer, or a front side extending from the rear side of the wearer. The width direction W is a direction orthogonal to the longitudinal direction L. [

The absorbent article 10 has a topsheet 20, a backsheet 22 and an absorbent body 30 between the topsheet 20 and the backsheet 22. The topsheet 20 faces the skin side of the wearer during use. During use, the backsheet 22 faces away from the skin of the wearer. The absorbent body 30 extends along the longitudinal direction L of the absorbent article.

The absorbent article 10 may have a wing 40 and a hip flap 50. [ The wing (40) is folded back to the non-skin side of the crotch part of the wearing article during use. The hip flap 50 is a portion that bulges in the width direction W from the rear side of the wing 40. The hip flap 50 is a portion bulging outward beyond the outer edge of the absorbent body 30 in the width direction W. [

The absorbent article 10 has a discharging port facing area S1 opposed to a discharging port (e.g., vaginal opening) of the wearer during use. The excretory compartment facing area S1 corresponds to a region of the crotch of the wearer, that is, a region disposed between the legs of the wearer, in which the absorber 30 is present. In the absorbent article 10 having the wings 40, the excretion area opposing area S1 corresponds to a region between the wings 40 where the absorber 30 exists.

2, the absorbent article 10 has adhered portions 42, 52, and 70 formed on the non-skin surface side of the backsheet 22. The adhesive portions 42, 52, and 70 are areas where a pressure-sensitive adhesive for fixing the absorbent article 10 to the wearing article is formed. The adhesive portion includes a main body adhesive portion 70, a wing adhesive portion 42, and a flap adhesive portion 52.

The main body adhesive portion 70 is formed in a region overlapping with the absorbent body 30 in the thickness direction of the absorbent article. It is preferable that the main body adhesive portion 70 is extended continuously or intermittently from at least the discharge port opposing area S1 to the rear side of the absorbent article 10. The main body adhesive portion 70 may extend in the forward and backward directions L and may be formed in plural in the width direction W at intervals.

The wing attachment portion (42) is formed in the wing (40). The wing 40 is attached to the non-skin side of the article to be worn by the wing tacky portion 42 while being in contact with the article to be worn by the wearer during use. The flap adhering portion 52 is formed in 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 at the time of packaging of the absorbent article.

The absorbent article 10 further includes a tape member 60 disposed on the non-skin surface side of the backsheet 22 and disposed inside the outer edge of the absorbent article 10. Therefore, the tape member 60 is covered with the absorbent article 10 when viewed from the skin surface side.

The tape member 60 is configured to extend outward beyond the outer edge of the absorbent article 10. As an example, the tape member 60 may be formed of a stretchable sheet. In this case, the wearer stretches the tape member 60, so that the tape member 60 extends outward beyond the outer edge of the absorbent article 10.

As another example, the tape member 60 may be formed of a Z-folded sheet. In this case, the wearer stretches the tip end of the tape member 60, so that the folded tape member 60 is deployed, whereby the tape member 60 extends outward beyond the outer edge of the absorbent article 10.

The tape member 60 may be a tape for post-processing and may be extended to such an extent that it is attached to the main body adhesive portion 70 in a state in which the absorbent article 10 is rounded. The tape member 60 may be made of any material as long as it can be attached to the main body adhesive portion 70. Preferably, the tape member 60 is made of a material that is more likely to stick to the body adhesive portion 70 than the topsheet 20. In addition, the tape member 60 may not have a pressure-sensitive adhesive.

The tape member 60 has the fixing portion 62 fixed to the non-skin surface of the absorbent article 10 and the tip end portion of the tape member 60 in the extending direction is directed toward the side opposite to the fixing portion 62 It is. In this case, when the tape member 60 is extended to the outside of the outer edge of the absorbent article 10, a force acts on the fixed portion 62 of the tape member 60 only in the extending direction. As a result, the force applied to the fixing portion 62 can be made as small as possible, so that the fixing strength of the tape member 60 can be maintained.

The user can extend the tape member 60 outward beyond the outer edge of the absorbent article 10 after the use of the absorbent article 10 only in the forward and backward directions L Reference). Since the tape member 60 is disposed inside the outer edge of the absorbent article 10 on the non-skin surface side of the backsheet 22 during use, body fluid such as menstrual blood is not attached to the tape member 60 Do not. The user can attach the tape member 60 extended outwardly to the adhesive portion 70 formed on the other portion of the backsheet 22 after use of the absorbent article 10 by rotating the absorbent article 10 in a circular It can be maintained in a lean state. Here, since the body fluid such as menstrual blood does not adhere to the tape member 60, deterioration of the bonding force between the tape member 60 and the adhesive portion 70 can be prevented. Thus, the absorbent article 10 can be prevented from being slightly rounded It can be easily maintained.

The surface of the dried absorbent article 10 is free of body fluids because the absorbent article 10 is dried with the surface on which the body fluids such as menstrual blood are adhered. Thus, the user can cleanly use the absorbent article 10 after use.

In addition, the user can leave the used absorbent article 10 on a small space near the one end in a small rounded state. Therefore, the user can attach the new absorbent article 10 to the wearing article such as underwear, and after disposing the undergarment or clothes, the user can dispose the used absorbent article 10 in the trash can or the like. Further, under a situation where there is no trash box near which the absorbent article 10 is disposed, the user may take the small-sized absorbent article 10 in a bag.

Since the tape member 60 is formed on the non-skin surface side of the backsheet 22 and does not extend outward beyond the outer edge of the absorbent article 10 during use of the absorbent article 10, The member (60) does not directly touch the skin of the wearer. Therefore, it is possible to reduce discomfort or discomfort during use.
