Description

  The present invention relates to a tape-type disposable diaper. More specifically, a three-dimensional gather disposed on both sides of the absorber, which can be spread toward the outside of the absorber so that the three-dimensional gather functions effectively, and effectively prevents urine leakage from the diaper. The present invention relates to a disposable tape type diaper.

  In recent years, as diapers for infants or elderly people / handicapped persons, for example, a tape-type disposable diaper 100 shown in FIG. 22, disposed so as to cover the surface of the absorber 22, at least a part of the top sheet 18 made of a liquid permeable material, and disposed so as to cover the back surface of the absorber 22, a liquid impermeable material A disposable diaper having a fastening tape 11 and a fixing tape 11 for fixing the back body 20 and the back body 6 disposed on the back body 6 side is widely used. Such a tape-type disposable diaper 100 can be worn by fastening each fastening tape 11 to the fastening region 13 disposed in the front body 2 of the diaper via the side of the wearer. it can.

  According to the tape-type disposable diaper 100, the excrement of the wearer passes through the liquid-permeable portion of the top sheet 18 and is absorbed by the absorbent body 22, and is usually composed of a liquid-impermeable material. Leakage to the outside is prevented by the back sheet 20, and excrement can be held inside the diaper. In addition, the front body 2 and the back body 6 of the diaper are fixed to each other by the fastening tape 11 so that the wearer can easily attach the diaper. In such disposable diapers, for example, the three-dimensional gathers 26 (26a, 26b) are formed by folding back the side sheets 19 that constitute the inner surface of the diaper (see, for example, Patent Document 1).

  The above-described three-dimensional gather 26 is a member for preventing leakage of the urine excreted by the wearer, and is a leak-proof wall configured to be able to stand up three-dimensionally. In FIG. 4, it forms by folding back the side seat | sheet 19 arrange | positioned on the surface of the side flap of a diaper. By arranging such a three-dimensional gather 26, it is said that leakage from a leg opening or the like of the diaper (so-called “lateral leakage”) can be prevented.

  However, in such a tape-type disposable diaper, when the inner surface of the diaper is worn on the wearer, the three-dimensional gathers arranged on both sides of the absorber do not spread to the left and right of the absorber. There is a problem that the three-dimensional gather may not function normally because it may be crushed by the buttocks.

  Furthermore, when the three-dimensional gather is crushed so as to cover a part of the surface of the absorber as described above, the front of the absorber absorbs urine, that is, the absorber for receiving excrement such as urine. There is a problem that the substantial surface area is reduced and the urine excreted by the wearer cannot be absorbed well. In particular, the three-dimensional gather is often crushed on the lower side of the body when worn, and it is necessary to prevent the three-dimensional gather from falling on the absorbent body in the back body where the absorption capacity is necessary because urine wraps around. However, for example, for a bedridden wearer, the three-dimensional gather is likely to be crushed under the body at the time of wearing, and it is difficult for the caregiver to specify the position of the three-dimensional gather. It will become apparent.

  In addition, since this three-dimensional gather is composed of a water-repellent material, when urine is excreted on the three-dimensional gather that has been crushed so as to cover the surface of the absorber, the surface of the three-dimensional gather is transmitted. There was also a problem of easily leaking from the opening around the leg of the diaper.

  Furthermore, for example, in the case of an adult diaper, a tape-type disposable diaper and a urine pad may be used in combination, and in recent years, a relatively large and wide urine pad is often used. Such a urine pad must be mounted on the absorbent body of a tape-type disposable diaper, that is, so as to fit between a pair of three-dimensional gathers. There was also a problem of increasing the caregiver's burden of care.

  The present invention can be expanded toward the outside of the absorber so that the three-dimensional gathers arranged around the absorber function effectively, i.e., to be an appropriate arrangement position of the three-dimensional gathers. The present invention provides a tape-type disposable diaper capable of effectively preventing urine leakage.

  As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention connect a solid gather to a fastening tape that extends from the back of the diaper and is bent on the inner surface of the diaper. By arranging the connected tension members and interlocking with the operation of spreading the fastening tape toward the outside in the width direction of the diaper, the three-dimensional gather can be spread to the left and right of the absorber, The present invention was completed by conceiving that the problems could be solved.

  The “front body” is a portion (reference numeral 2 in the figure) that covers the wearer's ventral side (front of the body) when the disposable diaper is attached to the wearer like the disposable diaper 1A shown in FIG. "Inseam" is the part that covers the inseam of the wearer when the disposable diaper is attached to the wearer (reference numeral 4 in the figure), and the "rear body" is when the disposable diaper is attached to the wearer. It shall mean the part which covers a wearer's back side (body back) (symbol 6 in the figure).

  Further, in the tape-type disposable diaper of the present invention, the “inner side surface of the diaper” refers to a surface that comes into contact with the wearer's skin when the diaper is worn, and the “outer surface of the diaper” The surface located on the clothing side of the wearer when the diaper is worn, on the opposite side of the inner surface of the diaper.

  The “one-piece type” includes a top sheet, a back sheet, and an absorbent body. An absorbent body that has an absorption / holding function is interposed (built in) between the top sheet and the back sheet, so that the mounting function is provided. This means a diaper of a type integrally formed with a top sheet and / or a back sheet.

[2] Configuration of the disposable diaper of the present invention:
The tape-type disposable diaper of the present invention is composed of the front body 2, the crotch part 4, and the back body 6, as in the tape-type disposable diaper 1A shown in FIGS. 1A and 1B. Is made of a liquid permeable material and is arranged so as to cover the upper surface of the absorber 22, and a back sheet 20 is made of a liquid impermeable material and is arranged so as to cover the lower surface of the absorber 22. And at least a pair of left and right three-dimensional gathers 26 (26a, 26b) disposed on both sides of the absorbent body 22 and the left and right side edges 6a, 6b of the back body 6, At least a pair of fastening tapes 11 for fixing the body 6 and the front body 2 and a fastening region 13 formed on the front body 2 for fastening the fastening tape 11 are provided.

  And in the tape-type disposable diaper 1A of the present invention, each of the pair of fastening tapes 11 extended from the left and right side edges 6a, 6b of the back body 6 is arranged with the top sheet 18 in the initial state of use. It is arranged in a state of being folded on the inner side surface of the diaper on the side that has been made. In FIG. 1A and FIG. 1B, two (that is, two pairs) fastening tapes 11 are extended from the left and right side edges 6a and 6b of the back body 6, respectively. The example folded by the inner surface of the diaper is shown.

  Furthermore, the tape-type disposable diaper 1A of the present invention has a base portion 12 that is a predetermined distance away from the side edges 6a, 6b of the back body 6 of the pair of fastening tapes 11a, 11b arranged in a folded state. One end portion 70x is connected, and the other end portion 70y is connected to the three-dimensional gather 26 arranged on the same side of the pair of three-dimensional gathers 26 (26a, 26b) arranged on both sides of the absorber 22. Are connected to each other, and when the diaper is used, each of the pair of fastening tapes 11 arranged in a folded state is used as shown in FIGS. 1C and 1D. The three-dimensional gather tension members 70a and 70b connected to the fastening tapes 11a and 11b are interlocked by expanding the left and right side edges 6a and 6b of the body 6 outward. 0a, connected standing gather 26a, be extended 26b of outward in the width direction of the diaper is configured to be in 70b.

  Thus, the tape-type disposable diaper of the present invention is interlocked with the operation of spreading the fastening tape folded on the inner surface of the diaper toward the outer side in the width direction of the diaper (that is, the three-dimensional gather tension member) ), The three-dimensional gather can be spread toward the outside of the absorber, and urine leakage from the diaper can be effectively prevented.

  More specifically, the tape-type disposable diaper of the present invention is a base material constituting the fastening tape by spreading the fastening tape toward the outside in the width direction of the diaper with the side edge of the back body of the diaper as a fulcrum. The three-dimensional gather tension member may be pulled outward in the width direction of the diaper by a distance corresponding to twice the length from the connecting portion with the three-dimensional gather tension member to the side edge of the back body. In conjunction with this, the three-dimensional gather can be expanded toward the outside of the absorber.

  In addition, the tape-type disposable diaper of the present invention can stand up (spread) a three-dimensional gather in conjunction with the fastening tape as described above even when the urine pad is mounted on the absorber. The urine pad can be easily mounted on the absorbent body, and the caregiver's burden of care can be reduced.

  In the tape-type disposable diaper 1A shown in FIG. 1A, the fastening tape 11a arranged on the left side of the paper surface of FIG. 1A and the three-dimensional gather 26a arranged on the left side of the side edge of the absorber 22 are the first three-dimensional gather tension. The fastening tape 11b disposed on the right side of the paper surface in FIG. 1A and the solid gather 26b disposed on the right side edge of the absorber 22 are coupled by the second solid gather tension member 70b. The three-dimensional gathers 26a and 26b can be widened outwardly in the width direction of the diaper via the three-dimensional gather tension members 70a and 70b.

  In the tape-type disposable diaper of the present invention, it is preferable that the other end portion of the three-dimensional gather tension member is fixed to the upper end portion side than the central portion from the lower end portion to the upper end portion of the three-dimensional gather. By comprising in this way, when moving a three-dimensional gather interlock | cooperating with a fastening tape, the front end side of a three-dimensional gather can be extended favorably right and left.

  Further, in the tape-type disposable diaper 1A shown in FIGS. 1A and 1B, one end portion 70x of the three-dimensional gather tension member 70 is formed of the base material portion 12 of the pair of fastening tapes 11 bent on the inner side surface of the diaper. 2A and FIG. 2A show an example in which the diaper is connected to a part of the surface facing the inner surface of the diaper (hereinafter, this surface may be referred to as “the inner surface of the base material portion”). As in the tape-type disposable diaper 1B shown in FIG. 2B, the three-dimensional gather tension member 70 is a diaper of the base material portion 12 of the pair of fastening tapes 11 with one end 70x bent to the inner surface of the diaper. The surface on the opposite side to the surface facing the inner surface may be connected to a part of the surface (hereinafter, this surface may be referred to as “the outer surface of the substrate portion”).

  Thus, as long as one end of the three-dimensional gather tension member is connected to the base material portion of the pair of fastening tapes, it may be connected to the inner surface of the base material portion. It may be connected to the outer surface of the material portion. When one end of the three-dimensional gather tension member is connected to the outer surface of the base material portion, the outer side of the base material portion is not related to the position of the fastening member arranged on the leading end side of the fastening tape. Since it is possible to connect to any position on the surface, the length of pulling the three-dimensional gather can be adjusted in a wider range. That is, one end of the three-dimensional gather tension member can be connected to a position closer to the tip portion of the fastening tape, and the three-dimensional gather can be spread more favorably on the left and right sides of the absorber.

  When one end of the three-dimensional gather tension member is connected to the outer surface of the base material portion of the fastening tape, as shown in FIGS. 2A and 2B, in the three-dimensional gather tension member 70, An opening 71 is formed in a region that overlaps the distal end portion of each fastening tape 11 that is arranged in a folded state so as to pinch the distal end portion of the fastening tape 11 and spread it outward in the width direction of the diaper. It is preferable. By configuring in this way, as shown in FIG. 2C, the leading end portion of the fastening tape 11 can be spread toward the outside of the diaper through the opening 71 of the three-dimensional gather tension member 70.

  Here, FIG. 2A is a partially cutaway sectional view showing another embodiment of the tape-type disposable diaper of the present invention, and is a view showing a state where the tape-type disposable diaper is developed and viewed from the top sheet side. . FIG. 2B is a schematic cross-sectional view showing a C-C ′ cross section of the tape-type disposable diaper shown in FIG. 2A. Furthermore, FIG. 2C is an enlarged perspective view schematically showing a state when the fastening tape of the tape-type disposable diaper shown in FIG. 2A is spread outside the diaper. Moreover, in FIG. 2A-FIG. 2C, about the thing comprised similarly to each element of 1 A of disposable diapers shown to FIG. 1A, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In addition, when one end of the three-dimensional gather tension member is connected to the outer surface of the base material portion of the fastening tape, instead of the above-described opening 71 (see FIG. 2A), for example, FIG. Like the tape-type disposable diaper 1C shown in 3A and 3B, in the three-dimensional gather tension member 70, the tip of the fastening tape 11 is overlapped with the tip of the pair of fastening tapes 11 arranged in a folded state. A cut line 72 may be formed for picking up the portion and spreading it outward in the width direction of the diaper. Such a cut line 72 is broken to form an opening portion, and the leading end portion of the fastening tape 11 is picked from the opening portion, so that the fastening tape 11 can be spread outward in the width direction of the diaper. . Thereby, the same effect as tape type disposable diaper 1B shown in Drawing 2A-Drawing 2C can be acquired.

  In addition, the above-mentioned cut line of the three-dimensional gather tension member refers to a broken line (perforation) in which several straight or curved cuts (cut portions) are continuously formed. In addition, such a cut line was configured such that the shape of the cut portion after the break was a shape corresponding to the shape of the tip portion of the fastening tape, for example, a semicircular shape or a U-shape. It is preferable. Moreover, there is no restriction | limiting in particular about the space | interval (interval of a perforation) etc. of a cut line of a cut line, For example, the user and caregiver of a diaper can be fractured comparatively easily with a finger etc. It suffices to be configured.

  Here, FIG. 3A is a partially cutaway sectional view showing still another embodiment of the tape-type disposable diaper of the present invention, and is a view showing a state in which the tape-type disposable diaper is developed and viewed from the top sheet side. is there. FIG. 3B is a schematic cross-sectional view showing a D-D ′ cross section of the tape-type disposable diaper shown in FIG. 3A. Moreover, in FIG. 3A and FIG. 3B, about the thing comprised similarly to each element of the disposable diaper 1A shown to FIG. 1A, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In addition, one in which one end of the three-dimensional gather tension member is connected to the outer surface of the base material portion of the fastening tape is excellent in productivity. For example, in the tape-type disposable diaper 1A shown in FIG. 1A, after one end 70x of the three-dimensional gather tension member 70 is once connected in a state where the fastening tape 11 is spread, the fastening tape 11 is attached to the inner surface of the diaper. 2A and 3A, the tape-type disposable diapers 1B and 1C are disposed after the fastening tape 11 is bent toward the inner side of the diaper. One end portion 70 x of the three-dimensional gather tension member 70 can be joined to the outer surface of the base material portion 12 constituting the fastening tape 11.

  As described above, the tape-type disposable diaper of the present invention has a three-dimensional gather according to the length from the connecting portion with the three-dimensional gather tension member to the side edge of the back body in the base material part constituting the fastening tape. A distance to be spread outward in the width direction of the diaper is determined. For this reason, in the tape type disposable diaper of this invention, the length from the connection part with a solid gather tension member in the base material part which comprises a fastening tape to the side edge of a back body is 5-80 mm. Is preferable, and it is still more preferable that it is 10-30 mm. By comprising in this way, a solid gather can be functioned more effectively at the time of diaper wear. The above-mentioned “length from the connecting portion with the three-dimensional gather tension member to the side edge of the back body” means the rearmost part of the portion where the three-dimensional gather tension member is joined to the base material part constituting the fastening tape. It is the length of the base material part from the position from the side edge of the body to the side edge of the back body of the diaper. That is, it is the length of the base material part from the side edge of the back body of the part which is not connected (fixed) to the three-dimensional gather tension member.

[2-1] Fastening tape:
As shown in FIGS. 1A and 1B, the tape-type disposable diaper of the present invention comprises a front body 2 and a back body 6 arranged so as to extend from the left and right side edges 6a, 6b of the back body 6. At least a pair of fastening tapes 11 for fixing are provided. 1A and 1B, two fastening tapes 11 are arranged on each of the left and right side edges 6a, 6b of the back body 6, and each of the pair of fastening tapes 11a, 11b is The three-dimensional gather members 26a and 70b are connected (coupled) to the three-dimensional gathers 26a and 26b arranged on the same side edge side.

  In such a fastening tape, a base material sheet serving as a base material portion of the fastening tape is connected to the side edge of the back body of the diaper, and is disposed in the vicinity of the front end of the base material sheet at the front body of the diaper. Fastening members that can be fastened to the wearing area are arranged.

  In the tape-type disposable diaper of the present invention, a pair of fastening tapes may be disposed on the left and right side edges of the back body, and the pair of fastening tapes may be connected to the three-dimensional gather by a three-dimensional gather tension member. In addition, two or more pairs of fastening tapes may be arranged on the left and right side edges of the back body, and all the fastening tapes may be fixed to the solid gathers by the solid gather tension members. That is, in the tape-type disposable diaper of the present invention, a pair of three-dimensional gathers can be extended to the left and right of the absorber in conjunction with the operation of spreading the fastening tape toward the outside in the width direction of the diaper. The above fastening tape and solid gathers should just be connected by the solid gather tension member.

  In general, in adult tape-type disposable diapers, two fastening tapes are extended to the left and right side edges, respectively. In the tape-type disposable diaper extended two by two, it is preferable that at least a pair of fastening tapes arranged on the lower side (that is, the crotch side) is connected to a three-dimensional gather by a three-dimensional gather tension member. .

  The fastening member of the fastening tape may be an adhesive fastener that is fixed by an adhesive, but it is preferable to use a mechanical fastener (surface fastener) that is fixed by mechanical coupling. The mechanical fastener has an advantage that, in addition to high fastening force, the fastening force does not decrease even if the attachment / detachment is performed a plurality of times.

  For example, a tape-type disposable diaper 1A shown in FIGS. 1A and 1B is an example in which a mechanical fastener 46 is used as a fastening member. A hook material 46a is attached near the front end of the fastening tape 11, while a front patch 13a made of a loop material 46b is attached to the front body 2, and the fastening tape 11 is attached to the front patch 13a. It is comprised so that it can stop.

  Moreover, when the solid gather tension member 70 is connected to the inner surface of the base material portion 12 of the fastening tape 11 as in the tape-type disposable diaper 1A shown in FIGS. 1A and 1B, this fastening tape. 11 and the three-dimensional gather tension member 70 are preferably temporarily fixed in a state before use. By comprising in this way, the wobbling of the fastening tape 11 can be effectively prevented. In addition, the above-mentioned “temporary fixing” means that it is fixed so as to be peelable by the force of a human hand.

  Such temporary fixing is preferably performed by fastening the fastening member of the fastening tape 11 to the three-dimensional gather tension member. For example, when a hook material of a mechanical fastener is used as a fastening member of the fastening tape 11, the hook material is a three-dimensional gather tensile member by making the three-dimensional gather tension member 70 a material that can be engaged with the hook material. It can be temporarily fixed by engaging with. Moreover, when an adhesive fastener is used as the fastening member of the fastening tape 11, the temporary fixing can be satisfactorily performed with the adhesive fastener by using a material from which the three-dimensional gather tension member 70 is peeled. Of course, temporary fixing may be performed separately from the fastening member by temporary bonding with a hot melt adhesive or the like.

[2-2] Solid gather tension member:
The three-dimensional gather tension member is a member for connecting (connecting) the fastening tape folded to the inner side surface of the diaper and the three-dimensional gather arranged on the same side edge side. It is a connecting member for expanding the three-dimensional gathers to the left and right of the absorber in conjunction with the operation of spreading outward on the side edges. Specifically, one end of the pair of fastening tapes arranged in a folded state is connected to the base material part that is a predetermined distance away from the side edge of the back body, and is arranged on both sides of the absorber. It is the connection member by which the other edge part was connected to the solid gathers arrange | positioned at the same side edge side of a pair of solid gathers.

  Although there is no restriction | limiting in particular about the raw material which comprises a three-dimensional gather tension member, For example, a woven fabric, a nonwoven fabric, urethane, a film etc. can be mentioned, Especially the nonwoven fabric which consists of thermoplastic resins, such as a polypropylene, polyethylene, and polyester, is used. It is preferable. Moreover, there is no restriction | limiting in particular also about the kind of nonwoven fabric, The conventionally well-known nonwoven fabric etc. which were manufactured by various manufacturing methods, such as card embossing, a spun bond, and SMS, can be used suitably.

  Moreover, it is preferable that the three-dimensional gather tension member connects the folded fastening tape and the three-dimensional gather as much as possible with no slack. By configuring in this way, in conjunction with the operation of spreading the fastening tape toward the outside in the width direction of the diaper, when spreading the three-dimensional gathers to the left and right of the absorber, it is possible to eliminate the waste of the tensile distance, The three-dimensional gather can be pulled right and left by a good and necessary distance.

  Moreover, there is no restriction | limiting in particular about the length of the width direction of a solid gather tension member, and as explained so far, it connects with a fastening tape and a solid gather, and a solid gather is interlocked with the movement of a fastening tape. Any material that can be pulled may be used. 2A and 3A, when one end portion 70x of the three-dimensional gather tension member 70 is connected to the outer surface of the base material portion of the fastening tape 11, the tip of the fastening tape 11 is used. The width of the fastening tape 11 (more specifically, the base constituting the fastening tape so that the portion can be expanded outward in the width direction of the diaper via the opening 71 and the cut line 72. The width of the material portion is preferably wider than the width of the material portion. The above-mentioned “length in the width direction of the three-dimensional gather tension member” refers to a length in a direction orthogonal to the direction from one end portion to the other end portion of the three-dimensional gather tension member.

  Further, for example, in the tape-type disposable diaper 1A shown in FIG. 1A, the length in the width direction of the three-dimensional gather tension member is the same length on one end side and the other end side (that is, one side The width of the three-dimensional gather tension member is the direction from one end to the other end. However, it may not be constant.

  For example, although illustration is omitted, in the tape-type disposable diaper of the present invention, the other end of the three-dimensional gather tension member connected to the three-dimensional gather may be configured to be wide. By comprising in this way, the other edge part of a three-dimensional gather tension member can be connected with respect to the wide range of a three-dimensional gather, and it becomes possible to extend a three-dimensional gather to the left and right.

  As described above, in the tape-type disposable diaper of the present invention, the connection portion of the three-dimensional gather tension member to the three-dimensional gather is widened, and although not shown, the other end of the three-dimensional gather tension member is branched. Thus, by connecting (fixing) a wide range of solid gathers or a plurality of ranges, it is possible to spread the solid gathers to the left and right within a wider range.

  Moreover, as shown to FIG. 1A and FIG. 1B, it is preferable that a part of the three-dimensional gather tension | tensile_strength member 70 is temporarily fixed to the surface of the side which contact | connects the inner surface of a diaper. By comprising in this way, it can prevent effectively that the solid gathering tension | tensile_strength member 70 will float before use of a diaper. In addition, there is no restriction | limiting in particular about the method of temporary fixing, Using various methods, such as engagement by mechanical fasteners, very weak welding or pressure bonding by heat embossing or ultrasonic welding, adhesion by adhesives, such as hot melt adhesive, etc. Can do. In addition, in FIG. 1B, the example in the case of having the fastening part 73 which can be attached or detached to the inner surface of a diaper in the surface facing the inner surface of the diaper of the three-dimensional gather tension member 70 is shown. In this way, the temporary fixing by the fastening portion 73 is made detachable such as engagement by a mechanical fastener, so that the three-dimensional gather is pulled to the left and right of the absorber, and then temporarily fixed by the fastening portion 73 again. By fixing, the state where the three-dimensional gather was pulled right and left can be maintained.

[2-3] Solid gathering:
The tape-type disposable diaper of the present invention includes at least a pair of left and right three-dimensional gathers arranged on both sides of the absorbent body in order to prevent side leakage of urine excreted by the wearer. The three-dimensional gather is a member for preventing side leakage of the urine excreted by the wearer, and is a leak-proof wall configured to stand up three-dimensionally. By forming such a three-dimensional gather, the three-dimensional gather serves as a breakwater, and leakage from a leg-diameter opening or the like (so-called “lateral leakage”) can be effectively prevented.

  In the tape-type disposable diaper of the present invention, as described above, the three-dimensional gather and the fastening tape are connected by the three-dimensional gather tension member, and the fastening tape is directed outward in the width direction of the diaper. The three-dimensional gathers can be expanded to the left and right of the absorber in conjunction with the operation of spreading. As a result, the position of the three-dimensional gather can be adjusted so that the three-dimensional gather can function effectively (that is, the three-dimensional gather can be prevented from being crushed under the body), and urine leakage from the diaper is effective. Can be prevented.

  The structure of a three-dimensional gather can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, as in the disposable diaper 1A shown in FIGS. 1A and 1B, an elastic material (a three-dimensional gather elastic material 36 (36a, 36b) is sandwiched and fixed between layers of the water-repellent sheet 32 (32a, 32b), and the three-dimensional gather It is possible to suitably use a material in which a gather is formed by the contraction force of the stretchable material 36. The three-dimensional gathered stretchable material 36 can be sandwiched and fixed, for example, at a folded portion of the water-repellent sheet 32. The other end portion 70y of each three-dimensional gather tension member 70 is a wall portion of the outer side of the diaper of the three-dimensional gather 26 in an upright state (that is, a pair of three-dimensional gathers 26a and 26b arranged on both sides of the absorber). It is connected to the wall portion on the side opposite to the wall portion arranged on the absorber 22 side.

  The three-dimensional gather may be separately provided with a water-repellent sheet for three-dimensional gather, or may be formed by a part of the sheet material constituting the diaper. For example, the disposable diaper 1 </ b> A shown in FIGS. 1A and 1B is an example in which the three-dimensional gathers 26 a and 26 b are formed by a part of the water-repellent sheet 32 constituting the side sheet 19. Such a water-repellent sheet may be a non-woven fabric produced by a method such as card embossing or spunbond, but a non-woven fabric sheet such as SMS or SMMS having a high waterproof property is more preferable.

  The three-dimensional gather may be an inward gather that tilts toward the inside of the diaper, or a three-dimensional gather (such as a C-folded gather or a Z-folded gather) in which a bent portion or a folded portion is formed in a part of the height direction. You can also For example, the disposable diaper 1A shown in FIG. 1A and FIG. 1B is an example in which the three-dimensional gather 26 (26a, 26b) is inverted and gathered.

[2-4] Fastening area:
A fastening area | region is an area | region for fastening the fastening member arrange | positioned at the fastening tape, and is arrange | positioned at the front body of a diaper. For example, in the tape-type disposable diaper 1A shown in FIG. 1A, a hook material 46a is provided near the tip of the fastening tape 11, and the front body 2 of the diaper is made of a loop material 46b as the fastening region 13. A front patch 13a is attached. By fixing the fastening tape 11 (more specifically, the hook material 46a of the fastening tape 11) to the fastening region 13 (front patch 13a), the opening around the waist of the diaper and the leg A surrounding opening is formed and a diaper can be worn.

  In addition, about the fastening area | region which comprises the tape type disposable diaper of this invention, there will be no restriction | limiting in particular if it can fasten the fastening tape demonstrated until now, It is to a conventionally well-known tape type disposable diaper. What was comprised similarly to the fastening area | regions, such as the used front patch, can be used suitably.

[3] Other components of disposable diapers:
As shown in FIGS. 1A and 1B, the disposable diaper of the present invention includes a top sheet 18, an absorber 22, and a back, in addition to the fastening tape 11, the three-dimensional gather 26, and the fastening region 13 described so far. A sheet 20 or the like is provided.

[3-1] Absorber:
The absorber is a member for absorbing and holding the wearer's urine. The absorber is made of an absorbent material because it needs to absorb and retain the wearer's urine and body fluid. Usually, the absorber is interposed between the top sheet and the back sheet by being sandwiched between the top sheet and the back sheet and sealing the peripheral edge thereof.

  Examples of the absorbent material constituting the absorber include conventionally known absorbent materials usually used for disposable diapers and other absorbent articles, such as fluff pulp, super absorbent polymer (Super Absorbent Polymer; hereinafter referred to as “SAP”). And a hydrophilic sheet. Use fluff pulp made of wood pulp or non-wood pulp defibrated, SAP as sodium polyacrylate, hydrophilic sheet as tissue paper, absorbent paper, hydrophilized non-woven fabric Is preferred.

  These absorbent materials are usually used as a single-layer or multi-layer mat. Under the present circumstances, 1 type may be used independently among the said absorptive materials, and 2 or more types may be used together. Especially, what combined about 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be uniformly mixed in each mat of fluff pulp, or may be arranged in layers between the layers of the multilayer fluff pulp.

  In addition, a sheet (second sheet) for diffusing liquid such as urine and body fluid may be incidentally disposed on the surface side of the absorber (for example, between the absorber and the top sheet). . When this second sheet is attached, due to the wearer's posture, etc., even when the space on the back side of the top sheet is not sufficiently formed, the absorption rate of urine, body fluid, etc. is difficult to decrease, and the absorption rate decreases. It is possible to prevent leakage of urine and body fluids.

  Examples of the material constituting the second sheet include hydrophilic and liquid-permeable materials such as woven fabric, non-woven fabric, porous plastic, and fluff pulp. Examples of these constituent materials include polypropylene, polyethylene, polyester, rayon, acetate, or composite fibers thereof, and pulp. As the pulp, crimped fibers such as curly cellulose fibers can be suitably used.

  Although there is no restriction | limiting in particular about the shape of an absorber, The shape used in the conventional disposable diaper and other absorbent articles, for example, a rectangular shape, an hourglass type, a gourd type, a T shape etc. can be mentioned.

  The entire absorbent body is preferably encapsulated by a hydrophilic sheet. Such a configuration has an advantage that SAP can be prevented from leaking from the absorber and shape stability can be imparted to the absorber.

[3-2] Top sheet:
A top sheet is a sheet | seat arrange | positioned so that the upper surface (surface located in a wearer's skin side at the time of mounting | wearing of a diaper) may be coat | covered. At least a part (all or a part) of the top sheet is made of a liquid-permeable material because the absorber disposed on the lower surface side (back surface side) needs to absorb the wearer's urine. Usually, at least near the surface of the absorber, it is made of a liquid-permeable material that can permeate the wearer's urine and body fluid. As long as at least a part is made of the liquid permeable material, the entire top sheet is not necessarily made of the liquid permeable material.

  Examples of the liquid permeable material constituting the top sheet include a woven fabric, a nonwoven fabric, and a porous film. Among these, it is preferable to use a non-woven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon and subjected to a hydrophilic treatment. There is no restriction | limiting in particular also about the kind of nonwoven fabric, The conventionally well-known nonwoven fabric manufactured by various manufacturing methods, such as air through (card hot air), card | curd embossing, and a spun bond, can be used suitably.

  The top sheet may be composed of a single sheet material, but may be composed of a plurality of sheet materials.

[3-3] Back sheet:
A backsheet is a sheet | seat arrange | positioned so that the back surface (surface located in the side far from a wearer's skin at the time of mounting | wearing of a diaper) may be coat | covered. The back sheet is made of a liquid-impermeable material because it is necessary to prevent the wearer's urine from leaking outside the diaper.

  There is no restriction | limiting in particular about the arrangement position of a back seat | sheet. From the viewpoint of preventing leakage of urine absorbed by the absorber, it is preferable that a back sheet is disposed at least in a portion where the absorber exists.

  Examples of the liquid-impermeable material constituting the backsheet include a liquid-impermeable film made of a resin such as polyethylene, and among these, a microporous polyethylene film is preferably used. This microporous polyethylene film has a large number of fine pores of 0.1 to several μm, and is liquid impervious but has moisture permeability, so that the inside of the diaper can be prevented from being steamed There is.

  A cover sheet may be bonded to the outer surface side of the back sheet. This cover sheet is used to reinforce the back sheet and improve the feel (tactile feeling) of the back sheet.

  Examples of the material constituting the cover sheet include woven fabric and non-woven fabric. Especially, it is preferable to use the dry nonwoven fabric and wet nonwoven fabric which consist of thermoplastic resins, such as polyethylene, a polypropylene, and polyester.

[3-4] Various elastic materials:
In the tape-type disposable diaper of the present invention, it is preferable to arrange an elastic material around the legs and arrange an elastic material around the waist.

  The leg circumference elastic material is an elastic material arranged along the leg circumference opening. By arranging the leg-stretchable material, a gather (leg gather) rich in stretchability can be formed in the leg-surrounding opening. Therefore, it is difficult to form a gap around the leg, and urine leakage from the opening around the leg can be effectively prevented.

  It is preferable that this leg-around elastic material is disposed at a portion outside the standing line of the three-dimensional gather. With such a configuration, it is possible to improve the wearing feeling and wearing feeling of the crotch part while ensuring a sufficient leakage preventing effect of the three-dimensional gather.

  The waist elastic material is an elastic material arranged along the waist opening. By arranging the elastic material around the waist, a gather (waist gather) rich in elasticity can be formed in the waist opening. This waist gather makes it difficult for gaps to be formed around the waist, preventing urine leakage from around the waist, and improving the fit of the diaper to the wearer, thereby preventing the diaper from falling down.

  In the tape-type disposable diaper 1A shown in FIG. 1A, a belt-like waist elastic member 42 is disposed along the edge of the back body 6 of the diaper, and a leg elastic member 40 is disposed along the leg opening. It is an example. In addition, the belt-shaped waist circumference elastic material 42 can be comprised with elastic foams, such as a urethane foam. In the illustrated example, the waist elastic member 42 is disposed only on the back body (back side), but the waist elastic material may be disposed on the front body (abdominal side).

  For these stretchable materials, after considering the degree of shrinkage of gathers, etc., the constituent material, the elongation rate of the material, the stretched state at the time of fixing, etc. may be determined.

  As an elastic material, the elastic material which has been used with the conventional disposable diaper can be used conveniently. Specific examples include elastic rubber, elastic film, elastic foam (urethane foam, etc.), etc. in addition to natural rubber flat rubber and synthetic rubber (urethane rubber, etc.) elastic thread. it can.

  The stretchable material is preferably fixed in the stretched state in order to exert a sufficient stretch force. For example, when the elastic material is a flat rubber made of natural rubber or a thread rubber made of an elastic thread of synthetic rubber, it is preferably fixed in an extended state of 120 to 400%, and fixed in an extended state of 200 to 300%. More preferably. By fixing in the extended state in such a range, it is possible to apply a sufficient expansion / contraction force without applying an excessive tightening force to the wearer.

  The stretchable material as described above is fixed to other constituent members of the diaper by an adhesive or other means. The fixing method may be, for example, adhesion using a hot melt adhesive or other highly fluid adhesive, or may be welding by heat such as heat sealing or ultrasonic waves.

[3-5] Application target:
The application object of the disposable diaper of this invention is not restricted to the 1 piece type tape-type disposable diaper demonstrated until now, For example, it can apply also to a 2 piece type tape type disposable diaper.

  The “two-piece type” means an absorbent main body that functions to absorb and retain the excretion fluid of the wearer (absorption / retention function), and a function that encapsulates the wearer's body (mounting function). The diaper is a type of diaper configured with an exterior member and having an absorbent main body disposed inside the exterior member.

  The said absorptive main body is a member provided with an absorber, a top sheet, and a back sheet as a component, and manufactures by inserting an absorber between a top sheet and a back sheet, and sealing the peripheral part of an absorber. be able to. Such an absorbent main body is configured to have a size that covers at least the crotch part of the diaper. However, in order to ensure the effect of preventing leakage, it is preferable to have a size that covers not only the crotch part but also a part of the front body and the back body. The absorptive main body can be fixed to the exterior member using, for example, a hot melt adhesive or the like.

  On the other hand, the exterior member is a member having a mounting function for encapsulating the wearer's body, and specifically, is a sheet-like member that forms the front body, the crotch part, and the back body. The two-piece type tape-type disposable diapers and pants-type diapers absorb and retain the excretion fluid of the wearer, and the absorption / holding function is exclusively performed by the absorbent main body. There is no need to use a liquid-impermeable material. Examples of the material constituting the exterior member include a nonwoven fabric composed of synthetic fibers made of polyethylene, polypropylene, polyester, and other thermoplastic resins.

[4] Tape type disposable diaper manufacturing method:
Hereinafter, the manufacturing method of the tape type disposable diaper of this invention is demonstrated in the example in the case of manufacturing the tape type disposable diaper 1B shown to FIG. 2A and 2B.

  In the method for producing a tape-type disposable diaper according to the present invention, first, an absorbent body 22 wrapped around a hydrophilic sheet and a leg-surround elastic member on the surface of a long sheet material (back sheet material) as a material of the back sheet 20. 40 is placed, and a sheet material (top sheet material) as a material of the top sheet 18 is placed on the surface.

  At this time, as the top sheet material, two types of a top sheet material corresponding to the center sheet and a top sheet material corresponding to the side sheet are used. A three-dimensional gather 26 is formed by providing a folded portion on the sheet material corresponding to the side sheet.

  Next, the fastening tape 11 used for the tape type disposable diaper of this invention is produced, and the produced fastening tape 11 is fixed to the site | part corresponded to the side edges 6a and 6b of the back body 6. FIG. Thereafter, the fastening tape 11 is bent toward the inner side surface of the diaper at the side edges 6 a and 6 b of the back body 6.

  Next, a three-dimensional gather tension member for connecting the fastening tape and the three-dimensional gather is produced. Specifically, the opening 71 is intermittently formed in a long sheet material, and then cut into a predetermined width in the flow direction.

  One end portion 70x of the three-dimensional gather tension member 70 obtained in this way is joined to the base material portion (the outer surface of the base material portion) of the fastening tape bent toward the inner surface of the diaper, and The other end portion 70 y of the three-dimensional gather tension member 70 is connected to the three-dimensional gather 26. The connection method (fixing method) to the fastening tape 11 and the three-dimensional gather 26 is not particularly limited. It can be fixed by heat sealing and other heat or ultrasonic welding.

  In addition, when it has further the fastening tape 11 which is not connected with the three-dimensional gathers 26a and 26b separately from the fastening tape 11a and 11b to which the three-dimensional gather tension member 70 is connected, it is used for the conventional tape type disposable diaper. A fastening tape is produced by the same method as the fastening tape, and the fastening tape is fixed to a portion corresponding to the side edge of the back body.

  In the diaper continuous body obtained as described above, a portion corresponding to the opening around the leg of the diaper is cut out in an arc shape and cut (R cut) to form an opening around the leg. Finally, the tape-type disposable diaper 1B is manufactured by cutting the diaper continuous body into individual diapers.

  The series of steps as described above can be continuously performed by mechanical means. For example, by adopting a method / apparatus such as continuously feeding a long sheet material from a roller, continuous production of a tape-type disposable diaper becomes possible, which contributes to an improvement in productivity. In addition, about the manufacturing method of the tape-type disposable diaper of this invention, it is not limited to the method mentioned above.
