Description

  The present invention relates to a disposable absorbent article which is applied to a wearer's crotch and absorbs excrement, such as a pants-type disposable diaper.

  In recent years, in the field of sanitary materials using disposable absorbent articles such as disposable diapers, disposable pants, sanitary napkins, etc., development of a thin and comfortable absorbent article has been demanded particularly for moderate and mild incontinent persons. As the above-mentioned disposable absorbent articles intended for moderate and mild incontinence, disposable absorbent articles that are thinner and more comfortable to wear are often required without interfering with the walking motion of the wearer.

  Conventionally used disposable absorbent articles, for example, pants-type disposable diapers, a waist opening is formed on the upper side of the abdomen and the dorsal side, and the crotch between the abdomen and the dorsal side A pants-type exterior sheet having leg openings formed on both sides is provided. Then, the absorbent material is sandwiched between the liquid-impermeable back sheet constituting the pants-type exterior sheet and the liquid-permeable top sheet on the skin surface side, and a bank ( A side solid gather) is known which is formed in a band shape. This side three-dimensional gather is composed of a liquid-impermeable side sheet with an elastic member such as rubber thread sandwiched at the top, and the side sheet rises when the elastic member contracts, thereby blocking urine, feces, etc. The leakage (lateral leakage) from both side edges of the diaper is prevented.

  Such a conventional disposable absorbent article is disclosed in Patent Document 1, for example.

International Publication No. WO01 / 39714

  However, like the disposable diaper described in Patent Document 1, if the dimension in the width direction of the side solid gather extending in the longitudinal direction is not uniform from one side end to the other side end in the longitudinal direction of the side solid gather, When the wearer wears the disposable diaper, the rising width of the side three-dimensional gather that has risen due to the contraction of the member is not uniform in the longitudinal direction. There is a risk of giving a sense of incongruity.

  Moreover, although the side three-dimensional gather is rising toward the skin surface side, the rising width of the standing portion of the conventional disposable absorbent article is as large as 20 mm to 60 mm, and when the wearer wears the disposable absorbent article, There is also a risk that the tip of the three-dimensional gather hits the wearer's skin more than necessary and gives discomfort.

  Also, when wearing a pants-type disposable absorbent article, there is also a problem that when the leg is inserted from the waist opening and the leg is taken out from the leg opening, the standing side solid gather is caught on the leg and it is difficult to pass the leg there were.

  This invention solves the said subject, and it aims at providing the disposable absorbent article which is smooth and easy to wear.

In order to solve the above problems, the invention according to claim 1 is characterized in that a waist opening is formed above the front abdomen and the back part, and leg openings are formed on both sides of the crotch part between the front part and the back part.

Accordingly, the wearer mainly fits the hip joint, and comfortable wearability can be ensured without giving the wearer a feeling of foreign matter or discomfort.
Further, according to the first to third aspects, since the dimension in the width direction of the side sheet is uniform in the longitudinal direction, and the dimension in the width direction of the adhesive layer (dimension of the coating width) is uniform in the longitudinal direction. The dimension in the width direction of the portion of the side sheet where the layer is not formed is also uniform in the longitudinal direction. Since there is an upright portion at a portion of the side sheet where the adhesive layer is not formed, the upright width of the upright portion can be appropriately adjusted to a desired size by adjusting the dimension in the width direction of the adhesive layer. Further, it is not necessary to newly provide an upright portion having a small standing width, and a conventionally used side seat can be used.
Further, according to claims 1 to 3, the standing width of the standing portion that rises upward due to the contraction of the elastic member for standing is smaller than the conventional one, and when the wearer wears the disposable absorbent article of the present invention, the leg is It can be worn smoothly without being caught on the standing part. Moreover, even if the said standing part contacts a wearer's skin, there is little discomfort compared with the past. In addition, since the size of the upright portion is smaller than that of the conventional one, the upright elastic member is easily warped by contraction.

  In particular, according to the third aspect of the present invention, a conventional disposable absorbent article in which almost the entire side seat is raised because the peripheral portion to which the standing seat elastic member is attached rises as the standing portion by contraction of the standing elastic member. Compared to, the rising width (standing width) is very small. Therefore, when a wearer is going to wear the disposable absorbent article of this invention, it can wear smoothly, without catching a leg on an upright part. Moreover, even if the said standing part contacts a wearer's skin, there is little discomfort compared with the past. In addition, since the size of the upright portion is smaller than that of the conventional one, the upright elastic member is easily warped by contraction.

  The outer sheet member 2 is formed of a synthetic resin fiber non-woven fabric or synthetic resin film having excellent air permeability and water repellency. Further, as shown in FIG. 3, the outer sheet member 2 is a substantially rectangular sheet member, of two long sides and two short sides constituting the outer periphery of the rectangle (here, two sides). The direction in which the long sides oppose each other is the left-right direction or the width direction, the direction in which the two short sides oppose each other is the longitudinal direction), and the middle portion of the opposing long sides (the portion corresponding to the crotch 2B) However, it is formed in a substantially hourglass shape in plan view that is cut out toward the opposing long sides. Here, in the outer sheet member 2, a portion having the largest notch depression is defined as a crotch portion 2 </ b> B, and the upper side in FIG. 3 is defined as the front abdominal portion 2 </ b> A and the lower side in FIG. Then, the outer sheet member 2 is folded in two with the crotch 2B as the center, and the left and right edges 11 of the front abdomen 2A and the left and right edges 12 of the back part 2C are joined by a joining means such as ultrasonic welding or heat welding. The side portions are joined to form a single hollow cylindrical waist opening S. Further, leg openings R are formed on the left and right sides by the above-described notched portions on both the left and right sides. Thus, the outer sheet member 2 is formed in a pants shape as shown in FIG.

  Further, elastic members 15 and 16 for the waist extend in the width direction at the edge portions (the edge portions located on the upper side in FIG. 1 or 2) of the front abdominal portion 2A and the back portion 2C constituting the waist opening S. It is attached in a state. In the following, the elastic member is preferably attached by adhesion with a hot melt adhesive.

  Further, as shown in FIG. 1 or 2, in the front abdominal part 2A and the back part 2C, the elastic member for the waistline is located at a position below the edge located above each and above the leg opening R. 17 and 18 are attached in the state extended in the width direction.

  In addition, leg leg elastic members 20 and 21 are attached to the leg leg part 19 constituting the leg opening R in a state of being extended along the edge of the leg leg part 19. The leg-surrounding elastic member 20 is provided in the leg-surrounding part 19 of the front abdomen 2A of the outer sheet member 2, and the leg-surrounding elastic member 21 is provided in the leg-surrounding part 19 of the rear back part 2C of the outer sheet member 2. Yes. In the outer sheet member 2, a predetermined gap is provided in the front-rear direction between the leg-surrounding elastic member 20 and the leg-surrounding elastic member 21, and a region C therebetween is substantially located at the crotch 4. It is set to be. As a modification, any one of the front leg elastic member 20 and the back leg elastic member 21 may be omitted.

  As shown in FIG. 4, the elastic members 15 to 18, 20, and 21 are sandwiched between the skin-side interior sheet 22 and the outer exterior sheet 23 that constitute the outer sheet member 2. Yes.

  Moreover, in the leg periphery part 19 of the outer side sheet member 2, the part to which the elastic members 20 and 21 for leg periphery are attached, and the part of the outer edge side comprise the pleated leg gather, Fits around the wearer's leg.

  Next, the absorptive main body 3 is demonstrated based on FIG.3 and FIG.4. The absorbent main body 3 includes a substantially sheet-like absorbent material 31 and side sheets 32 provided at both left and right end portions of the absorbent main body 3. Further, the absorbent main body 3 is configured by sandwiching an absorbent material 31 between a liquid-permeable top sheet 33 and a liquid-impermeable back sheet 34. The absorbent material 31 is a substantially sheet material having a substantially hourglass shape in plan view, and spreads in a belt shape in the front-rear direction around the crotch part 4. The absorbent main body 3 configured in this way is joined to the skin side of the crotch 2B of the outer sheet member 2. This joining is performed by applying an adhesive such as hot melt between the absorbent main body 3 and the outer sheet member 2 to form the adhesive layer 50. Further, in the side sheet 32 according to the present embodiment, the longitudinal dimension of the side sheet 32 is substantially equal to the longitudinal dimension of the absorbent main body 3, and the lateral dimension of the side sheet 32 is the side sheet. It is comprised so that it may become uniform from 32 longitudinal direction one side edge part to the other side edge part. As shown in FIG. 4, the adhesive layer 51 is formed between the folded back sheets 34 and the bottom surface of the folded back sheet 34 and the bottom surface of the top sheet 33 at both left and right end portions of the absorbent main body 3. The adhesive layer 52 is formed between and bonded to the upper surface of the top sheet 33 and the lower surface of the side sheet 32 (the lower surface of the lower side sheet 32c in FIG. 4). With this configuration, the absorbent material 31 is sealed in the absorbent main body 3.

  Further, the first standing elastic member 38 is attached to the vicinity of the free end of the side seat 32 so as to extend in the longitudinal direction over almost the entire length of the side seat 32. Due to the contraction of the first standing elastic member 38, the portion of the side seat 32 to which the first standing elastic member 38 is attached, that is, the peripheral portion of the first standing elastic member 38 of the side seat 32 is pleated, It will stand up. If the part of the side sheet 32 is a standing part 321, the standing part 321 functions as a three-dimensional gather and can effectively prevent leakage (lateral leakage) from both side edges of the disposable absorbent article by urinating urine and the like. it can.

  Further, the standing width P of the standing portion 321 according to the present embodiment is set to a very small amount as compared with the conventional case, and the value is, for example, about 0.5 to 5 mm. “Small amount” as used herein refers to a size that does not impair the function of the original three-dimensional gather even if it is small, that is, prevents leakage of urine and the like from both side edges of the disposable absorbent article 1. As long as the function as a breakwater is not impaired. For this reason, when the wearer wears the disposable absorbent article 1 according to the present embodiment, the standing width P of the standing portion 321 that rises upward due to the contraction of the first standing elastic member 38 is smaller than the conventional one. The leg can be worn smoothly without being caught on the upright part 321. Moreover, even if the standing part 321 contacts a wearer's skin, there is little discomfort compared with the past. Further, since the size of the upright portion 321 is smaller than that of the conventional one, it is likely to warp due to the contraction of the first upright elastic member 38.

  Further, the side seat 32 has a bent portion 32a that can be bent inward in the free end portion of the side seat 32 in the longitudinal direction, and the bent portion 32a is located in the vicinity of both end portions in the width direction of the absorbent main body 3. Provided. In addition, the elastic member 39 for 2nd standing is attached to the vicinity of the folding | turning edge part of the bending part 32a over the substantially full length of the side seat | sheet 32 in the longitudinal direction. By the contraction of the second standing elastic member 39, the vicinity of both side edges of the absorbent main body 3 itself is raised upward.

  As shown in FIG. 4, the side seat 32 is folded in two with the bent portion 32 a as an axis, and an upper side seat 32 b positioned on the upper side, and a lower side seat 32 c facing the upper side seat 32 b, In the meantime, the adhesive layer 40 having a uniform dimension in the width direction is formed over the longitudinal direction from the bent portion 32a to a predetermined distance inward in the width direction. As described above, the lower side sheet 32 c is joined to the top sheet 33 via the adhesive layer 53. Here, in the upper side sheet 32 b, a part where the adhesive layer 40 is formed is a base part 322, and a part located on the inner side in the width direction than the base part 322 is a standing part 321. Further, the distance from the tip of the standing part 321 to the upper surface of the top sheet 33 in the standing state is the standing width P of the standing part 321, and a predetermined distance for forming the adhesive layer 40, that is, the adhesive layer 40. Let the dimension in the width direction be Q. Note that an adhesive layer is not formed between the standing portion 321 and the lower side sheet 32 c, and the leading end portion of the standing portion 321 corresponds to the free end portion of the side sheet 32. Therefore, the upright portion 321 becomes a pleated three-dimensional gather that rises upward due to the contraction of the first upright elastic member 38 attached in the vicinity of the tip of the upright portion 321.

  With the configuration as described above, the dimension in the width direction of the side seat 32 is uniform from one end portion to the other end portion in the longitudinal direction of the side seat 32. Therefore, the contraction of the first standing elastic member 38 The rising portion 321 that rises easily and becomes uniform in the longitudinal direction, and as a result, the rising portion 321 is warped in a substantially arcuate shape that forms a beautiful arc as viewed from one side in the width direction. Accordingly, the wearer mainly fits the hip joint, and comfortable wearability can be ensured without giving the wearer a feeling of foreign matter or discomfort.

  Further, since the dimension in the width direction of the adhesive layer 40 is also uniform in the longitudinal direction, the dimension in the width direction of the portion of the upper side sheet 32b where the adhesive layer is not formed is uniform in the longitudinal direction. Since the part of the upper side sheet 32b where the adhesive layer is not formed is the standing part 321, the standing width P of the standing part 321 is appropriately corrected to a desired size by adjusting the dimension Q in the width direction of the adhesive layer 40. can do. For example, the standing width P of the standing portion 321 is set to be smaller than the dimension Q in the width direction of the adhesive layer 40. As shown in FIG. 4, the base portion 322 and the upright portion 321 of the side sheet 32 on which the adhesive layer 40 is formed are connected in the width direction, and when the dimension Q in the width direction of the adhesive layer 40 is increased, the base portion 322 The dimension to the free end of the side seat 32, that is, the dimension to the tip of the upright portion 321 of the side seat 32 is reduced, and as a result, the size of P that is the standing width of the upright portion 321 is also reduced. In addition, it is not necessary to newly provide a standing part with a small amount of standing width P, and a standing part having a desired standing width P can be obtained by using a conventionally used side sheet.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  For example, as shown in FIG. 5, in the upper side sheet 32b, the portions of the upper side sheet 32b in the vicinity of both ends in the longitudinal direction and in the vicinity of the middle part in the longitudinal direction are joined to the lower side sheet 32c in the longitudinal direction. Three joint portions 41 are formed. The joint portion on one side in the longitudinal direction is 41a, the joint portion on the other side is 41b, the joint portion in the middle is 41c, and the generic name is the joint portion 41. And between the junction part 41c and the junction part 41a and the junction part 41b which adjoin the junction part 41c in the longitudinal direction, the pocket opened in the width direction inner side by the upper side sheet 32b and the lower side sheet 32c, respectively. A portion 42 is formed. By forming the pocket portion 42 in this manner, even if the urine is excreted when the disposable absorbent article 1 is worn and placed in the lateral position, the urine etc. is temporarily stored in the pocket portion 42 and is absorbed as it is. It can be absorbed by the absorbent 31 of the main body 3. That is, an effect of preventing urine or the like from leaking by holding urine or the like in the pocket portion 42 can be achieved. Moreover, since the standing width | variety of the standing part 321 of the site | part of the upper side sheet | seat 32b which comprises the pocket part 42 is also small, it is easy to wear and comfortable wearability can be ensured. In the present embodiment, the two pocket portions 42 are arranged side by side with the joint portion 41c interposed therebetween. However, the standing widths of the standing side portions of the upper side sheet 32b constituting each pocket portion 42 are both long. Uniform in direction.

  Moreover, in the said embodiment, although the contact bonding layer 40 was formed between the upper side sheet | seat 32b and the lower side sheet | seat 32c facing the upper side sheet | seat 32b, it opposes the upper side sheet | seat 32b and the upper side sheet | seat 32b. The adhesive layer 40 may also be formed between the top sheet 33 and the adhesive layer 40 may also be formed between the upper side sheet 32b, the lower side sheet 32c facing the upper side sheet 32b, and the top sheet 33. May be. The pocket portion 42 is formed in the same manner, and the pocket portion 42 may be formed by the upper side sheet 32 b and the top sheet 33 facing the upper side sheet 32.

  Moreover, although the case where the side sheet 32 was folded in two was described in the above embodiment, the adhesive layer 40 having the dimension Q in the width direction can be formed without folding the side sheet 32 in half. Specifically, as shown in FIG. 6, a predetermined amount is provided between the side sheet 32 and the top sheet 33 facing the side sheet 32 from the width direction outer ends of the side sheet 32 or the top sheet 33 inward in the width direction. By the distance Q, the adhesive layer 40 having a uniform dimension in the width direction over the longitudinal direction is formed. Here, in the side sheet 32, a part where the adhesive layer 40 is formed is a base part 322, and a part located on the inner side in the width direction than the base part 322 is an upright part 321. Note that an adhesive layer is not formed between the standing portion 321 and the side sheet 32, and the leading end portion of the standing portion 321 corresponds to a free end portion of the side sheet 32. Further, the second standing elastic member 39 is attached to the vicinity of the outer end portion of the side seat 32 so as to extend in the longitudinal direction over almost the entire length of the side seat 32. With such a configuration, the upright portion 321 becomes a pleated three-dimensional gather that rises upward due to contraction of the first upright elastic member 38 attached in the vicinity of the distal end portion of the upright portion 321. In this embodiment, the bent portion 32a may or may not be provided. When the bent portion 32 a is not provided, as shown in FIG. 6, the side sheet 32 and the top sheet 33 may be formed as separate members and bonded to each other with the adhesive layer 40.

  Further, the pocket portion 42 can be formed by the side sheet 32 and the top sheet 33 of the absorbent main body 3. Specifically, as shown in FIG. 7, in the side sheet 32 extending in the longitudinal direction, the portions of the side sheet 32 in the vicinity of both ends in the longitudinal direction and in the vicinity of the middle part in the longitudinal direction are respectively joined to the top sheet 33, The joint part 41 is formed in three places, the joint part on one side in the longitudinal direction is 41a, the joint part on the other side is 41b, the joint part in the middle is 41c, and the generic name is the joint part 41. And the pocket part 42 opened in the width direction inner side by the side sheet | seat 32 and the top sheet 33 is formed between the junction part 41a and the junction part 41b adjacent to the junction part 41c in the longitudinal direction, respectively. By forming the pocket portion 42 in this manner, even if the urine is excreted when the disposable absorbent article 1 is worn and placed in the lateral position, the urine etc. is temporarily stored in the pocket portion 42 and is absorbed as it is. It can be absorbed by the absorbent 31 of the main body 3. That is, an effect of preventing urine or the like from leaking by holding urine or the like in the pocket portion 42 can be achieved. Moreover, since the standing width | variety of the standing part 321 of the site | part of the side seat | sheet 32 which comprises the pocket part 42 is also small, it is easy to wear and comfortable wearability can be ensured. In the present embodiment, the joint portions are provided at three locations and the pocket portions are formed at two locations, but more joint portions and pocket portions may be formed. Also in this embodiment, the two pocket portions 42 are arranged side by side with the joint portion 41c interposed therebetween, but the standing widths of the standing portions of the side seats 32 constituting each pocket portion 42 are both in the longitudinal direction. Is uniform.

  In the above embodiment, a predetermined interval is provided in the front-rear direction between the leg-surrounding elastic member 20 and the leg-surrounding elastic member 21, and the region C is set therebetween. You may make it the structure which is not.

  Moreover, although the said embodiment demonstrated the structure which provided the side sheet 32 comprised separately from the top sheet 33 in the width direction both ends of the absorptive main body 3, the side sheet 32 and the top sheet 33 are substantially made. It is good also as an integral structure. In this case, the standing width P of the standing portion 321 can be made very small by using a side sheet having a small width dimension without forming the adhesive layer 40.

  In the above embodiment, the standing width P of the standing portion 321 is the distance from the tip of the standing portion 321 to the top surface of the top sheet 33 in the standing state, but the tip of the standing portion 321 in the standing state. A distance from the upper part to the upper surface of the lower side seat 32c may be used as the standing width P of the standing part. 4 and 6, the adhesive layers 40, 50, 51, 52, and 53 are shown with a thickness, but this is exaggerated for the sake of clarity and is actually quite thin. Therefore, the distance from the tip end portion to the lower end portion of the standing portion 321 in the standing state can be set as the standing width P of the standing portion 321.

  Moreover, in the said embodiment, although the underpants type disposable absorbent article 1 which attached the absorptive main body 3 to the outer sheet | seat member 2 was demonstrated, the absorptive main body 3 single-piece | unit is mounted | worn with an existing diaper cover etc. and used.
