  For example, in Patent Documents 1 to 3, for the purpose of improving convenience at the time of wearing, after the waist portion is wrapped around the waist of the wearer, the end portion of the absorber portion is attached to the waist portion. A belt-type diaper that is fastened and worn is disclosed. Regarding the manufacturing method, Patent Document 3 discloses an improvement on a method for attaching a fastening member. However, it is difficult to manufacture a diaper stably at a high speed with the structure and method disclosed in this prior art.

  On the other hand, the above-mentioned patent documents 4 to 6 disclose a diaper in which a waist part composed of a member different from the diaper body is detachably joined to the diaper body by a fastener for the purpose of remounting. Yes. However, Patent Documents 4 to 6 do not describe the manufacturing method.

  An object of the present invention is to provide a wearing article that can be stably manufactured at high speed like a pants-type wearing article and that can be easily reattached like a belt-type diaper, and a method for producing the same.

  A certain wearing article according to the present invention has a front part covering the abdomen side of the wearer, a rear part covering the back side of the wearer, and an absorber straddling between the front part and the rear part, A wearable article in which a trunk opening and two leg openings are formed by joining the front part and the rear part to each other, wherein the front part and the rear part each extend in a waistline direction, and the trunk opening part A second edge opposite to the first edge, a third edge located at one end in the waistline direction, and a fourth edge located at the other end in the waistline direction A third edge of the front part and a third edge of the rear part are joined together, and a fourth edge of the front part and a fourth edge of the rear part are joined together. And two broken parts processed to break after wearing a part of the front part are separated from each other in the waist direction of the front part. And the two breaks are provided so as to essentially traverse the front from the first edge to the second edge of the front, and the two At least a part of the absorbent body is fixed in the first region between the rupture portions, and can be secured to the front portion on the skin surface side of the first region of the front portion. A possible first fastening part is provided, the first region of the front part being surrounded by the first edge, the second edge, the third edge and one of the breaks; the first edge of the front part; A second fastening portion capable of fastening to the front portion is provided in at least one region of the third region surrounded by the second edge, the fourth edge, and the other fractured portion.

In normal times, the wearable article may be worn as a pants-type wearing article in which the front and rear third edges are joined together and the front and rear fourth edges are joined together. it can.
When an emergency situation occurs during wearing of the present wearing article or when it is desired to confirm excretion, the wearer or an assistant (hereinafter referred to as “user”) is in front of the two breaking portions. Break the front and divide the front. Thereafter, the user overlaps the second region and the third region to form an overlapping portion, connects the second and third regions by the second fastening portion, and connects the overlapping portion to the first region. Reattachment is possible by fixing the first region to the second and / or third region via the first fixing part so as to cover the region. Therefore, the worn article can be worn as a worn article that has been remounted until it is replaced with another new worn article.

  Furthermore, this wearing article can also be used as a so-called belt-type diaper. In this case, the front part is broken at the two breaking parts before wearing. By this breakage, a long belt-like body portion is generated with the second region and the third region in the front portion being connected to the rear portion. Then, it wears like the said re-wearing.

  When this wearable article is used as such a belt-type diaper, the wearer can easily wear the worn article in the standing position.

  Here, since the conventional belt-type diaper has a long body portion, there is a disadvantage in that the speed cannot be increased in its manufacture. On the other hand, this wearable article is used as a belt-type diaper after the front part and the rear part are manufactured as a pants-type diaper having substantially the same length. Therefore, it is possible to increase the production speed as in the case of the pants-type diaper.

The part processed so that a front part can be divided into two, etc. are mentioned.
In addition, “the fracture part essentially crosses the front part from the first edge to the second edge of the front part” means that it can be torn by a human hand at the fracture part. For example, in the case of a perforated fracture, the perforation may not completely cross the front from the first edge to the second edge.
Further, the two breaking portions may be substantially orthogonal to the first edge and / or the second edge, or may be formed obliquely with respect to the first edge and the second edge and parallel to each other. Alternatively, they may be formed obliquely with respect to the first edge and the second edge and non-parallel to each other. Further, the shape of the fracture portion is not limited to a straight line, but may be a curved line.

In the present invention, the “second fastening portion” may be any one that can fasten and connect the second region and the third region to each other after the front portion is broken at the breaking portion.
The “first fastening portion” can fasten the first region to the second and / or third region so that the first region overlaps the connecting portion connected by the second fastening portion. I just need it.
The first fastening part and the second fastening part may be provided as separate first fastening members and second fastening members, respectively, or the first fastening part and the second fastening part may be integrated. The integrated fastening member may be divided into a first fastening part and a second fastening part by providing and splitting together with the front part at the breaking part.

As shown in FIG. 9, the belt-like body B may have a shape that becomes narrower as it goes to the end.

Reconfiguration: A method of reconfiguring the broken worn article is described. At the time of reconfiguration, the user first folds the second region A2, which is one end of the belt-shaped body B shown in FIG. 4A, toward the front as shown in FIG. As shown in FIG. 4C, the third region A3, which is the other end, is folded forward, and a part of the second region A2 (overlapping portion) and a part of the third region A3 (overlapping portion 100). And overlap each other. At this time, the user connects the two regions A2 and A3 by fixing the second region A2 and the third region A3 to each other by the second fixing member 12. Next, as shown in FIG. 4D, the user folds the absorbent body 2 to overlap the first region A <b> 1 on the overlapping portion 100 via the first fastening member 11. Thereby, 1st area | region A1 is fixed to 2nd and 3rd area | region A2, A3 of the belt-shaped trunk | drum B, and a pants-type diaper is reconfigure | reconstructed.

  That is, in the reconstructed wearing article, as shown in FIG. 5, both ends of the belt-shaped body B are joined by the second fastening member 12 to form the body opening BH, and the belt-shaped body The leg opening LH is formed by the part B, the remaining front part F and the absorber 2. Accordingly, the user can wear the reconstructed book wearing article as a pants-type wearing article.

Belt-type wearing items:
The worn article broken in FIG. 4A can also be used as a belt-type worn article.
In this case, the user performs the steps shown in FIGS. 4A to 4D while the wearer wraps the belt-shaped torso B around the waist. That is, a user performs the connection by the 2nd fastening member 12, and fixes the belt-shaped trunk | drum B of FIG.4 (c) to a wearer's waist. Next, after the user passes the absorbent body 2 through the wearer's crotch, as shown in FIGS. 4 (d) and 5, the user passes the remaining front part F through the first fastening member 11 to the belt-like body. Fastened to the overlapping portion 100 of the portion B.

Thus, when used as a belt-type wearing article, it is particularly convenient when wearing the wearing article alone in a standing posture.
The worn article may be used as a belt-type worn article by breaking the worn article in advance at the breaking portions 10A and 10B.

Production method:
Hereinafter, the manufacturing method of this wearing article is demonstrated.
As shown to Fig.6 (a), 1st sheet-like object S1 used as the front part 1F and 2nd sheet-like substance S2 used as the rear part 1B are mutually conveyed in parallel continuously.

The first and second fastening members 11 and 12 are attached to the first sheet-like material S1 that flows continuously.
Then, fracture | rupture parts 10A and 10B are formed between the 1st fastening member 11 and the 2nd fastening member 12 in 1st sheet-like object S1. The breaking portions 10A and 10B are formed along a direction substantially orthogonal to the flow direction X. The breaking portions 10A and 10B are formed, for example, by making perforations along a direction substantially perpendicular to the flow direction X of the first sheet-like object S1.
The absorber 2 is arrange | positioned so that it may straddle between 1st sheet-like material S1 and 2nd sheet-like material S2 after formation of the fracture | rupture parts 10A and 10B.
The order of these steps may be changed.

Thereafter, as shown in FIG. 6B, the absorbent body 2 is folded back so that the first sheet-like material S1 and the second sheet-like material S2 overlap each other.
After the folding, the first sheet material S1 and the second sheet material S2 are joined and cut between the adjacent absorbers 2. Thereby, one pants-type wearing article is generated.

  The sheet-like objects S1 and S2 can be constituted by, for example, a nonwoven fabric, a film, or the like. The first sheet-like material S1 and the second sheet-like material S2 may be formed by slitting one sheet to widen the interval, or may be composed of separate sheets.

  Moreover, the fastening members 11 and 12 in FIG. 6A may be arranged along the fractured portions 10A and 10B. The fastening members 11 and 12 may be disposed on both sides or one side of the first sheet-like object S1 along the flow direction X. However, the positions of the fastening members 11 and 12 are not limited to these, and may be other places. In the case where the first fastening member 11 and the second fastening member 12 are integrally formed as one member, in the step of forming the second fracture portion 10B, the first fastening member 11 and the second fastening member 12 For example, a fracture portion 10B made of perforations is processed at the boundary.

  After the absorbent body 2 is disposed on the first sheet-like material S1, the first fastening member 11 may be disposed on the absorbent body 2. In such a case, it is preferable that the first fastening member 11 is disposed in a portion where the absorbent body 2 and the first sheet-like material S1 overlap.

  You may further provide the process of trimming the part which comprises the said leg opening part LH in said 1st sheet-like material S1 and / or 2nd sheet-like material S2. This trim is a step of removing a trim portion T indicated by a two-dot chain line in FIG. By removing the trim portion, the fit is improved. In this step, wrinkles and creases are likely to occur around the cut portion, and problems are likely to occur when the absorber 2 is disposed. Therefore, this step is preferably performed after the arrangement of the absorber 2.

The process of arrange | positioning the elastic member 15 for waists (FIG. 2) may be added to 1st sheet-like object S1. The waist elastic member 15 improves the fit of the front portion 1F when the product is worn. Therefore, the function of preventing leakage is improved.
The process of arrange | positioning the elastic member 15 (FIG. 2) for waist to 2nd sheet-like material S2 may be added. The waist elastic member 15 improves the fit of the rear portion 1B when the product is worn.

  The waist elastic member 15 may be sandwiched between two sheet-like materials, or may be sandwiched between one folded sheet-like material.

  When the step of arranging the elastic member 15 for waist is added, the step of reducing stress other than the portion corresponding to the width of the absorbent body 2 (length in the longitudinal direction X) after the step of arranging the elastic member 15 for waist. It may be added. As a method for reducing the stress, for example, there is a method in which only the elastic member 15 is cut by embossing or the like so that the elasticity of the elastic member is not expressed. This step is preferably performed before the arrangement step of the fastening members 11 and 12.

Furthermore, the process of arrange | positioning the leg periphery elastic member 16 (FIG. 2) to 2nd sheet-like material S2 and / or 1st sheet-like material S1 may be added. The leg elastic member 16 is preferably sandwiched between two sheets.
The leg-hole elastic member 16 improves fit to the lower part of the buttocks when wearing the product. Therefore, the function of preventing leakage is improved.

The leg-hole elastic members 16 may be arranged in a straight line as shown in FIG. 7 (a), or may be arranged in a curved line as shown in FIG. 7 (b). When the leg-holes elastic member 16 is arranged in a curved shape, the leg-holes elastic member 16 is preferably arranged along a trim portion indicated by a two-dot chain line.
When the step of arranging the leg-hole elastic member 16 is added, it is preferable to add a step of reducing the stress of the elastic member 16 in the portion where the absorber 2 is arranged. This is because the absorber 2 is easily arranged.

  A step of disposing a body fit elastic member on the second sheet-like material S2 and / or the first sheet-like material S1 may be added. The elastic member for body fit is preferably sandwiched between two sheets. This body-fit elastic member improves the fit of the rear part when the product is worn. When adding this process, if the process of making the stress of the elastic member of the part which arrange | positions the absorber 2 small is added, the absorber 2 will become easy to arrange | position.

As described above, the absorbent body 2 is formed by laminating the liquid permeable sheet 24, the absorbent core 25, the liquid impermeable sheet P, the cover sheet 26, and the like. A step of providing the absorbent body 2 with the aforementioned three-dimensional gather 27, the elastic body 28, the cuff elastic member 29, and the like may be further added.
For example, the absorber 2 may be arranged 90 ° after being formed in a longitudinal flow state.

Hereinafter, a manufacturing method in the case where the rear portion 1B, the front portion 1F, and the crotch portion are formed from one sheet-like object S will be briefly described.
As shown to Fig.8 (a), the 1st and 2nd fastening member 11 and 12 adhere to the site | part used as the front part 1F in the wide sheet-like object S which flows continuously.
Thereafter, the first and second fractured portions 10 </ b> A and 10 </ b> B are formed at positions on both sides of the absorbent body 2 along a direction substantially orthogonal to the flow direction X. One of the two rupture portions 10 </ b> A and 10 </ b> B is formed at a portion of the sheet S between the first fastening member 11 and the second fastening member 12. The rupture portions 10A and 10B are formed so as to essentially cross the portion that becomes the front portion 1F along the direction substantially orthogonal to the flow direction X so that the front portion 1F can be divided in the waist direction. .

After the formation of the two breaking portions 10A and 10B, the absorbent body 2 is disposed at a position between the two breaking portions 10A and 10B of the sheet-like material S.
After the absorber 2 is arranged, a part of the sheet-like material S is cut out in order to form the leg opening LH between the adjacent absorbers 2.
The order of these steps may be changed.

  After performing each of the above steps, the sheet-like material S is folded back along the flow direction X with the approximate center of the absorbent body 2 as a boundary so that a folded portion is formed in the absorbent body 2 to become the front portion 1F. A site | part and the site | part used as the rear part 1B are piled up.

After the folding step, the portion between the adjacent absorbers 2 is joined and cut. That is, while the site | parts used as the front part 1F and the rear part 1B in the sheet-like article S are joined between the adjacent absorbers 2 and 2, the sheet-like article S is cut | disconnected for every wearing article. Thereby, one pants-type wearing article is generated.
The step of forming the leg opening LH may be performed after the folding step.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, in the above-described embodiment, the case where two breakage portions are provided has been described, but three or more breakage portions may be provided at the front portion.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention.

  The present invention can be used for wearing articles such as disposable pants and diapers.
