Description

  The present invention relates to a method for manufacturing a diaper having a belt.

A diaper with a belt is suitable for being worn by the wearer himself in a standing position. Examples of such diapers include diapers disclosed in the following three patent documents.
JP2003-93443 (Abstract) Special table 2004-508138 (WO2002 / 022062) (abstract) Special table 2004-516072 (WO2002 / 049568) (abstract)

In the diapers disclosed in these patent documents, the width of the belt is constant. In order to fit the back part of the diaper to the back surface (back part) of the wearer, it is preferable to widen the width of the belt. However, a wide belt deteriorates the wearing feeling in the wearer's abdomen.
On the other hand, if a belt having a wide width on the back surface of the wearer and a narrow width on the wearer's abdomen is employed, the shape of the belt becomes tapered and the belt material is wasted.

  Accordingly, an object of the present invention is to produce a diaper in which the back part of the diaper is easy to fit on the back surface of the wearer, the wearing feeling around the wearer's abdomen is good, and the belt material is not wasted. Is to provide a method. Furthermore, another object of the present invention is to improve the texture (or appearance) of diapers.

  A manufacturing method of a diaper according to the present invention includes a diaper main body having a front part covering the stomach side of the wearer, a back part covering the back side of the wearer, and a crotch part between the front part and the back part, and the back A diaper manufacturing method comprising first and second belts having end portions fixed to a portion and tightening a wearer's waist, wherein the first side portion and the second side portion are continuous in the transport direction. By cutting the web along a waved cutting line continuous in the longitudinal direction of the web while transporting the belt-shaped web having the plurality of belt-shaped first belt-shaped portions that gradually become thinner as approaching the tip. And a comb-shaped first divided web in which the first belt-like portions are connected to each other at the first side portion of the web, and a plurality of belt-like second belt-like portions that gradually become gradually thinner toward the tip. Each second strip A step of forming a comb-shaped second divided web in which the second side portions of the web are connected to each other, and the first divided web and the second belt-shaped portion overlap each other. And / or a step of shifting the phase of the second divided web along the web conveying direction, a step of temporarily joining the first and second belt-like portions overlapping each other, and a set of the first temporarily joined to each other. Forming a pair of the first and second belts by cutting each side of the first and second divided webs so as to include the first and second belt-like portions, and configuring the diaper body A step of disposing the first and second belts of each set at a predetermined pitch in the conveying direction of the continuum so as to overlap a portion constituting the back portion of the continuum; and a first disposed at the predetermined pitch. 1 and 2 A step of temporarily joining a belt to a portion constituting the back portion, a step of fixing one end portion of each belt at both ends in a waistline direction at a portion constituting the back portion, and the continuous body at the predetermined pitch And cutting into individual diapers.

Since the diaper manufactured by the method of the present invention becomes thinner as each belt approaches the tip, the belt does not get in the way around the wearer's abdomen, and the feeling of wear is good.
On the other hand, since the width of the belt is wide on the back surface of the wearer, the entire back portion of the diaper is easy to fit on the back surface of the wearer.
Moreover, since the belt-like belt is produced by cutting the web, the material is not wasted and the appearance is good.

In the present invention, `` temporary joining '' means joining the belt or member in a state where the member can be easily peeled from the belt or the diaper body without substantially damaging the belt or the diaper body. Generally, the “temporarily joined” portion is easier to peel than the “fixed” portion.
Further, in the present invention, the “diaper” includes a wearable article intended to absorb a small amount of urine such as a so-called incontinence pad, in addition to those that can absorb urine and stool.

  In a preferred embodiment of the present invention, when the first and second belts of each set are disposed, one end portions of the first and second belts are disposed so as to protrude from the side edges of the continuous body, When fixing one end portion of each belt, the one end portion protruding from the side edge of the continuous body is folded back, and the continuous body is sandwiched between the one end portion and each belt-shaped portion, and then the one end portion At least a part of the folded portion of the part is fixed in the vicinity of the side edge of the continuous body.

  In the present invention, when the belt is joined and fixed to the back portion without folding the belt, the joint portion between the belt and the back portion is easily peeled off when the belt is pulled during wearing. On the other hand, when the belt is folded back and the folded portion of the belt is joined and fixed to the back portion, even if the belt is pulled during wearing, the joined portion between the belt and the back portion is hardly peeled off.

  In another preferred embodiment of the present invention, the first side portion and the second side portion further expand the width by relatively displacing the first divided web and the second divided web in the width direction of the web. And when arranging the first and second belts of each set, substantially all of the first and second side portions at one end of the first and second belts protrude from the side edges of the continuum. When the one end of each belt is fixed, the one end projecting from the side edge of the continuous body is folded back, and the continuous body is sandwiched between the one end and each belt-shaped portion. After that, at least a part of the folded portion of each one end is fixed in the vicinity of the side edge of the continuous body.

  In the present embodiment, the widening step makes it possible to project one end of the belt greatly from the continuous body. Therefore, since one end of the belt is folded, almost all of the wide one end overlaps the back part, so that the wide one end does not protrude from the diaper main body. It is firmly fixed by the back part.

  The invention will be more clearly understood from the following description of preferred embodiments with reference to the accompanying drawings, in which: However, the examples and figures are for illustration and description only and should not be used to define the scope of the present invention. The scope of the present invention is defined only by the claims. In the accompanying drawings, the same part numbers in a plurality of drawings indicate the same or corresponding parts.

First embodiment:
Embodiments of the present invention will be described below with reference to the drawings.
Prior to the description of the manufacturing method, an example of a diaper that can be manufactured according to the present invention will be described with reference to FIGS.

  In FIG. 4A, the diaper includes a diaper main body 3, a first belt 1, and a second belt 2. The diaper main body 3 includes a front part 3f covering the abdomen side of the wearer, a back part 3b covering the back side of the wearer, and a crotch part 3c between the front part 3f and the back part 3b. The first and second belts 1 and 2 are provided so as to protrude from the back portion 3b to both sides in the waistline direction. Both belts 1 and 2 are for tightening the wearer's waist, as will be described later.

As shown in FIGS. 4A and 4C, the diaper main body 3 is formed by laminating a plurality of sheet-like members, an absorber, and an elastic member.
As shown in FIGS. 4A and 4C, the diaper main body 3 includes a top sheet 31 having liquid permeability, an absorbent body C, a back sheet 32 having liquid impermeability, and an outer sheet. 33 is laminated. The leak-proof wall (cuff) 34 may be provided on the top sheet 31.
In addition, the absorber C may have a fluff pulp and / or a super absorbent polymer obtained by pulverizing pulp. The absorber C may be airlaid pulp or the like.

  The leak barrier 34 prevents feces and / or urine from exiting the absorber C or diaper. The leak-proof wall 34 may be three-dimensional. The diaper body 3 may be provided with a plurality of elastic members 35 for preventing stool and / or urine from leaking from the diaper.

  Elastic members 36 and 37 that form waist gathers for suppressing the deviation between the wearer and the diaper may be disposed on the front portion 3f and the back portion 3b. The elastic members 35 to 37 may be thread rubber or flat rubber.

  One end portions (fixed end portions) 11 and 21 of the first and second belts 1 and 2 are fixed to both ends of the back portion 3b of the diaper body 3 in the waistline direction. One end portions 11 and 21 of the belts 1 and 2 are fixed by being sandwiched between a web constituting the leak-proof wall 34 and the back sheet 32, for example.

The first belt 1 has a first tapered portion (first belt-like shape) that is wide at the one end portion 11 and becomes narrower as it goes from the one end portion 11 to the other end portion (free end portion) 12. Part) 13). On the other hand, the width of the second belt 2 is wide at the one end 21, and a second taper-shaped portion (the first taper) whose width decreases from the one end 21 toward the other end (free end) 22. An example of a two-band part) 23.
The tapered portions 13 and 23 do not necessarily need to be formed into a smooth taper shape, and may have a strip shape that gradually decreases as the tip is approached.

  A first joining member 41 is fixed to the inner surface side of the other end portion 12 of the first belt. The first joining member 41 is joined to the outer surface side of the second belt 2 so as to be able to contact and separate (removably). In the diaper wearing state of FIG. 3D, the first joining member 41 is joined to the central portion 23 or the other end portion 22 of the second belt 2. Thereby, the 1st and 2nd belts 1 and 2 and the back part 3b are connected in an annular shape, and the diaper fits the wearer's torso. The wearer can adjust the fit by adjusting the position of the second belt to which the first joining member 41 is joined in accordance with his / her waistline.

  A second joining member 42 is fixed to the inner surface side of the front portion 3f of the diaper main body 3 in FIG. As shown in FIG. 3D, the second joining member 42 is joined to the outer surface side of the first and second belts 1 and 2 in a diaper wearing state. This makes it possible to place the diaper between the groins.

  In the present specification, the “inner surface side” refers to the side in contact with the skin, while the “outer surface side” refers to the side opposite to the inner surface side and exposed to the outside.

For example, a hook-and-loop fastener or an adhesive tape may be employed as each of the joining members 41 and 42. In the case of the present embodiment, the material constituting the leak-proof wall 34 and the first and second belts 1 and 2 is a nonwoven fabric, while the joining members 41 and 42 are male fasteners, and the male surfaces The fastener is engaged and joined to the surface of the nonwoven fabric.
In addition, the female surface fastener which engages with a male surface fastener may be provided in the belts 1 and 2.

Next, an example of a diaper manufacturing method will be described.
First, a method for manufacturing the pair of belts 1 and 2 will be described with reference to FIG.
As shown in FIG. 1A, the plurality of first joining members 41 are moved at a predetermined pitch λ (FIG. 1B) while the belt-like continuous web W is conveyed in the direction of the arrow (conveyance direction) Y. Fix to the web W. The first joining member 41 is fixed to a surface corresponding to the back side of the paper surface of FIG. 1A (a surface that becomes the inner surface side of the manufactured diaper belt).

  Next, as shown in FIG. 1B, the web W is cut along a waveform cutting line L continuous in the longitudinal direction of the web W while the belt-like web W is conveyed. Thus, comb-shaped first and second divided webs W1 and W2 are generated. The first divided web W1 has a plurality of tapered first tapered portions 13 and the first tapered portions 13 are continuous with each other at the first side portion S1 of the web W. The second divided web W2 has a plurality of tapered second tapered portions 23, and the second tapered portions 23 are continuous with each other on the second side portion S2 of the web W. The first and second tapered portions 13 and 23 have tapered shapes that become thinner from the first and second side portions S1 and S2 toward the free end portions 12 and 22, respectively. The first and second side portions S1 and S2 become the fixed end portions 11 and 21 of the first and second belts after the cutting step of the side portions S1 and S2 described later, respectively.

  The web W is cut so that the first joining members 41 are arranged in the first tapered portions 13. The wavelength of the cutting line L that cuts the web W is equal to the pitch λ at which the first joining members 41 are disposed.

  Subsequently, as shown in FIG. 1C, the phase of the first divided web W1 and / or the second divided web W2 is set so that the first tapered portion 13 and the second tapered portion 23 overlap each other. Shift along the conveyance direction Y of the web W. For example, the first tapered portion 13 and the second tapered portion 23 overlap each other by transporting one of the first or second divided webs W1 and W2 with a delay of (λ / 2 + nλ). At this time, the first divided web W1 and the second divided web W2 are overlapped so that the first joining member 41 is disposed at a position between the first divided web W1 and the second divided web W2.

  Thereafter, the first and second tapered portions 13 and 23 overlapping each other are temporarily joined to each other. In the first temporary joining, the first joining member 41 is engaged in the vicinity of the fixed end portion 21 of the second belt 2 and the space between the first tapered portion 13 and the second tapered portion 23 is set. This is done by loosely joining with hot melt resin. By the first temporary joining, the first and second tapered portions 13 and 23 that are overlapped with each other can be conveyed without being separated from each other.

After the first temporary bonding, the side portions S1 and S2 of the first and second divided webs W1 and W2 are cut so as to include the first and second tapered portions 13 and 23 temporarily bonded to each other. Thus, a set of the first and second belts 1 and 2 is formed.
In this cutting, it is possible not only to separate the first and second belts 1 and 2 for each group, but also to remove (trim) a part of the side portions S1 and S2. Such cases are also included in the scope of the present invention. This trimming may be performed before or after the cutting process of the side portions S1 and S2.

  After the separation, the interval between adjacent pairs of belts 1 and 2 is increased to a predetermined interval P as shown in FIG. As a result, the pitch P of each pair of belts is equal to the pitch P or the total length of the diaper to be generated later.

Next, as shown in FIG. 2A, the first and second belts 1 and 2 of each set are arranged at a predetermined pitch P in the conveyance direction Y of the continuous body 30. The continuous body 30 is, for example, a composite body in which a leak-proof wall 34 is fixed to the top sheet 31 of FIG. 4B, and is cut later to form the diaper main body 3. The first and second belts 1 and 2 of each set are disposed so as to overlap with the back portion 3b (FIG. 3B) of the continuous body 30, and are temporarily joined to the portion by hot melt resin or the like. (Second provisional bonding). By this second temporary joining, the first and second belts 1 and 2 of each set can be conveyed in a state where they are not separated from the continuous body 30.
In the arrangement step, the belts 1 and 2 are arranged in a state where the fixed end portions 11 and 21 of the first and second belts 1 and 2 protrude from the side edge 30e of the continuous body 30.

After the second temporary joining, the fixed end portions 11 and 21 protruding from the side edge 30e of the continuous body 30 are folded back as shown in FIG. Accordingly, the continuous body 30 is sandwiched between the fixed end portions 11 and 21 and the tapered portions 13 and 23. Thereafter, at least a part of the folded portion of each of the fixed end portions 11 and 21 is fixed in the vicinity of the side edge 30e of the continuous body 30.
That is, the fixed end portions 11 and 21 of the belts 1 and 2 are fixed at both end portions in the waistline direction at the portion constituting the back portion 3b (FIG. 3B).

  After the belts 1 and 2 are fixed, as shown in FIG. 2 (c), the absorbent body C, the outer sheet 33 and the like are laminated on the continuous body 30, and the diaper main body 3 (FIG. 3 (b)). A corresponding laminate is produced. Thereafter, the continuous body 30 is cut at the predetermined pitch P and cut into individual diapers. As indicated by phantom lines at the time of cutting, the fixed end portions 11 and 21 of the belts 1 and 2 may be cut so as not to cut the tapered portions 13 and 23. In this case, the cut ends 11e and 21e (FIG. 3 (b)) of the fixed end portions 11 and 21 remain on the front portion 3f. Note that only the continuous body 30 may be cut at a position where the fixed end portions 11 and 21 of the belts 1 and 2 are not cut.

  In the step of cutting the continuum 30, a part of the continuum 30 constituting the crotch portion 3c may be removed (trimmed). This trimming may be performed before or after the step of cutting the continuous body 30.

  Thus, the diapers shown in FIGS. 3B and 3C are generated. As shown in these drawings, in the manufactured diaper, the first and second belts 1 and 2 are folded to the inner surface side IN of the back portion 3b. The first and second belts 1 and 2 may be folded to the outer surface side OUT in FIG.

  The fixed end portion 11 of the first belt 1 in FIG. 3B is folded back at one end in the waistline direction of the back portion 3b and fixed to the back portion 3b. The fixed end portion 21 of the second belt 2 is folded at the other end in the waistline direction of the back portion 3b and fixed to the back portion 3b. When the diaper is shipped, the crotch portion 3c is folded in two, and the front portion 3f is temporarily joined onto the first belt 1 and / or the second belt 2 by the second joining member 42. May be.

  When the back sheet 32 is laminated on the continuous body 30, the fixed end portions 11 and 21 of the belts 1 and 2 are sandwiched between the leak-proof wall 34 and the back sheet 32 of FIG. In a state, it may be adhered to both the leak-proof wall 34 and the back sheet 32. In this case, the belts 1 and 2 are firmly fixed to the diaper main body 3.

Next, the wearing method of this diaper is demonstrated.
The wearer opens the folded first belt 1 and second belt 2 in FIGS. 3B and 3C to release the first and second temporary joints. As shown in FIG. 3D, the wearer joins the leading ends of the belts 1 and 2 to each other on the stomach side of the wearer with the first joining member 41 in a standing posture. After the joining, the wearer joins the front part 3f to the first belt and / or the second belts 1 and 2 joined to each other via the second joining members 42 and 42, and wears a diaper. To wear.

Second embodiment:
FIG. 5A to FIG. 8C show a second embodiment.
In the second embodiment, as clearly shown in FIG. 8 (a), the first and second belts 1 and 2 are substantially entirely attached to the wide fixed end portions 11 and 21 of the first and second belts 1 and 2, respectively. It is fixed to the diaper body 3.
The diaper with the belt fixed in this way is not attractive because the wide fixed end portions 11 and 12 do not protrude from the diaper main body 3, and the joining portion between the belts 1 and 2 and the diaper main body becomes large. The belts 1 and 2 are firmly fixed to the diaper main body 3.

Next, an example of a method for manufacturing the diaper will be described.
In this example, after the web W shown in FIG. 5 (b) is cut, the first divided web W1 and the second divided web W2 are widened before the belts 1 and 2 are temporarily joined. That is, as shown in FIG. 5C, the first divided web W1 and the second divided web W2 are relatively displaced in the width direction of the web, with the first side S1 and the second side S2 being in the width direction of the web. To be widened. In this widening, only one divided web W1 (W2) may be moved in the width direction of the web, or both of the two divided webs W1 and W2 may be moved in the width direction of the web.

Due to the widening, as shown in FIG. 6A, when the first and second belts 1 and 2 of each set are arranged, the fixed end portions 11 and 21 of the first and second belts 1 and 2 are arranged. The first and second side portions S1 and S2 are arranged substantially in a state protruding from the side edge 30e of the continuous body 30.
After this arrangement, as shown in FIG. 6B, the fixed end portions 11 and 21 protruding from the side edge 30e of the continuous body 30 are folded back, and the fixed portions 11 and 21 are folded back. Is fixed in the vicinity of the side edge 30e of the continuum 30.

Incidentally, in each of the above embodiments, the first and second belts 1 and 2 in FIG. 4B are joined to the leak-proof wall 34 of the top sheet 31, but as shown in FIG. The second belts 1 and 2 may be joined to the top sheet 31 itself or to both the top sheet 31 and the leak-proof wall 34.
Moreover, as the continuous body 30 in FIG. 2A, the back sheet 32 and / or the outer sheet 33 in FIG. 4B is adopted, and the first inner side or outer surface side of the back sheet 32 or the outer sheet 33 is used. The second belts 1 and 2 may be fixed.

In each of the above embodiments, the first and second belts 1 and 2 in FIG. 3C are folded back to the inner surface side of the diaper, but the first and second belts 1 and 2 are folded back to the outer surface side. Good. In this case, the first and second belts 1 and 2 are placed on the inner surface side of the diaper.
Further, the folding of the belts 1 and 2 may be performed with the first and second side portions S1 and S2 of FIG. 1A folded before the web W is cut. After cutting, the first and second side portions S1 and S2 of the first and second divided webs W1 and W2 in FIG. 1B may be folded back and executed.

  Further, in each of the above embodiments, the fixed end portions 11 and 12 of the first and second belts 1 and 2 are folded back. It is also possible to fix the first and second belts 1 and 2 to the continuum 30 without folding them back so that they fall within the width of this, and this case is also included in the scope of the present invention. Furthermore, the first and second belts 1 and 2 are not folded back, but both sides of the continuous body 30 are folded and the fixed ends 11 and 12 of the belts 1 and 2 are fixed to the folded portions. Good.

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, the first joining member 41 may be provided on the outer surface side of the second belt 2.
Temporary joining may be realized by welding by sonic other than hot melt resin and hook-and-loop fasteners.
Moreover, when a diaper is used as an incontinence pad, the absorber C may be made small.
Further, the diaper may have a structure that allows other usage in addition to the usage (wearing state) shown in FIG.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.

  The present invention can be applied to the manufacture of diapers.
