Disclosure of Invention

In the wearing article of document 1, the end portion of the elastic member is bonded to one of the two nonwoven fabrics. The front and rear waist portions are joined to each other at both ends thereof by so-called side seal portions to form a pants configuration.

Therefore, the joining form of the two nonwoven fabrics and the joining form of the side seal portion are different from each other, and thus the appearance is deteriorated.

Accordingly, an object of the present invention is to provide a pants-type wearing article having a good appearance and a method for manufacturing the same.

A pants-type wearing article of the present invention comprises front and rear waist portions 3 covering the waist of a wearer, and an absorbent body 2 laid over the front and rear waist portions 3,

the front and rear waistline portions 3 are each formed by sandwiching a plurality of elastic members 32 extending in the waistline direction X between two sheets 31,

the two sheets 31 are welded and bonded to each other at a plurality of first bonding portions 4 intermittently arranged in the girth direction X and intermittently arranged in a direction Y orthogonal to the girth direction X,

the front and rear waist regions 3 are fusion-bonded to each other at a plurality of second bonding portions 5 intermittently arranged along the orthogonal direction Y at end portions E3 in the waist circumferential direction X of the front and rear waist regions 3,

the first joint 4 and the second joint 5 are formed of the same pattern as each other.

On the other hand, the method for manufacturing the article of the present invention includes:

a conveying step of conveying the plurality of continuous sheets W4 in a conveying direction L;

a clamping step of clamping the plurality of continuous elastic members F conveyed in the conveying direction L between the plurality of continuous sheets W4;

a generating step of fusion-bonding the plurality of continuous sheets W4 to each other at the plurality of first bonding portions 4 in a predetermined pattern intermittently in the conveying direction L and intermittently in a direction Y orthogonal to the conveying direction L to generate a pair of waist-girth continuations 40 serving as front and rear waist-girth portions 3;

a step of setting up the absorbent main body 2 between the pair of waist line continuations 40;

a folding step of folding the absorbent main body 2 in two so that the pair of waist line continuations 40 overlap each other;

a fusion bonding step of fusion bonding the pair of waist circumferential continuum 40 to each other in the same pattern as the predetermined pattern at the end E3 of the portion of the front and rear waist portions 3 and at the second bonded portion 5 between the mutually adjacent first bonded portions 4 of the plurality of first bonded portions 4; and

a cutting step of sequentially cutting the pair of waist circumferential continuous bodies 40 at the end portions E3 to obtain respective pants-type worn articles.

According to the present invention, the first joint portions 4 for the two sheets and the second joint portions 5 corresponding to the so-called side seals are formed in the same pattern. The pattern formed by the plurality of joining

portions

4, 5 is continuous and has a uniform feeling. Thus, the appearance of the article is improved.

In the present invention, the pattern identity means that at least one of the three elements of the pitch in the orthogonal direction Y between the joining portions, the shape and the size of the joining

portions

4 and 5 is the same or similar. In the present specification, the pitch between the joining portions in the orthogonal direction Y refers to a distance in the orthogonal direction Y between the centers of the joining portions adjacent to each other.

Detailed Description

In a preferred article, a pitch P2 in the orthogonal direction Y of the second joint 5 intermittently arranged in the orthogonal direction Y is equal to a pitch P2 in the orthogonal direction Y of the first joint 4 intermittently arranged in the orthogonal direction Y.

On the other hand, in a preferred method, the step of fusion-bonding is performed so that a pitch P2 in the orthogonal direction Y of the second bonded parts 5 intermittently arranged in the orthogonal direction Y is equal to a pitch P2 in the orthogonal direction Y of the first bonded parts 4 intermittently arranged in the orthogonal direction Y.

In these cases, at least the pitch P2 in the pattern is equal, and thus, the appearance of the article is enhanced.

In another preferred article, the shape and size of each second joint 5 of the plurality of second joints 5 are substantially the same as the shape and size of each first joint 4 of the plurality of first joints 4.

On the other hand, in another preferred method, the fusion-bonding step is performed so that the shape and size of each of the second bonding portions 5 of the plurality of second bonding portions 5 are substantially the same as the shape and size of each of the first bonding portions 4 of the plurality of first bonding portions 4.

In these cases, the shapes and sizes of the respective

joint portions

4 and 5 are also the same in the pattern except for the pitch P2, and the appearance of the article is significantly improved.

In a preferred article, a length L1 in the girth direction X of each of the first joining sections 4 and the second joining sections 5 is shorter than a length L2 in the orthogonal direction Y.

In a preferred method, the secondary fusion bonding is performed in the predetermined pattern in which the length L1 in the girth direction X of each of the first bonded portion 4 and the second bonded portion 5 is shorter than the length L2 in the orthogonal direction Y.

In these cases, since the length L1 in the girth direction X of each of the

joint portions

4 and 5 is short, the distance between the

joint portions

4 and 5 can be increased, and wrinkles with good appearance can be easily formed. Further, since the length L2 in the orthogonal direction Y is long, a strong bonding force is easily secured.

In a preferred article, the front and rear waist portions 3 include:

a bonding region α C located between the plurality of first joint parts 4 and the plurality of second joint parts 5 adjacent to the plurality of second joint parts 5 among the plurality of first joint parts 4, and in which the elastic member 32 is bonded to at least one of the two sheets 31 at the bonding region α C with an adhesive CE, and

a non-adhesive region α N comprising the plurality of second joints 5 and contiguous with the adhesive region α C.

In a preferred method, in the front and rear waist portions 3,

the step of performing the sandwiching in a state where the elastic member 32 is bonded to at least one of the two sheets 31 with an adhesive CE in a bonded region α C between the plurality of first joint portions 4 and the second joint portion 5 adjacent to the plurality of second joint portions 5 among the plurality of first joint portions 4,

the step of fusion-bonding is performed so that the plurality of second joints 5 are arranged in the non-adhesive region α N adjacent to the adhesive region α C.

In these cases, the adhesive CE was not applied to the non-adhesive region α N, and the non-adhesive region α N including the second joint 5 was soft, so that the skin contact performance was significantly improved when the user was asleep in the lateral direction.

In a preferred article, a row formed by a plurality of the first joint portions 4 adjacent to the plurality of second joint portions 5 among the plurality of first joint portions 4 is arranged apart from a row formed by the plurality of second joint portions 5 in the girth direction X. That is, the first joint portion 4 does not overlap with each of the second joint portions 5, the first joint portion 4 does not contact with the second joint portions 5, and the row of the first joint portion 4 and the row of the second joint portions 5 are disposed adjacent to each other.

In a preferred method, the generating step and the fusion-bonding step are performed such that a row formed by a plurality of first bonded portions 4 adjacent to a plurality of second bonded portions 5 among the plurality of first bonded portions 4 and a row formed by the plurality of second bonded portions 5 are arranged apart in the girth direction X. That is, the step of creating and the step of fusion-bonding are performed so that the second bonding portions 5 do not overlap the first bonding portions 4, the second bonding portions 5 do not contact the first bonding portions 4, and the rows of the second bonding portions 5 and the rows of the first bonding portions 4 are arranged adjacent to each other.

In these cases, the second joining portion 5 does not overlap or contact the first joining portion 4, so that the appearance of both the joining

portions

4 and 5 is improved, and a hard lump is less likely to be generated on the side.

Features described and/or illustrated in connection with one or more of the embodiments or the following examples can be used in the same or similar manner in one or more other embodiments or other examples, and/or in combination with or instead of features of other embodiments or examples.

Examples

The invention may be more clearly understood from the following description of preferred embodiments with reference to the accompanying drawings. However, the examples and the drawings are only for illustration and description and should not be used to limit the scope of the present invention. The scope of the invention is to be determined solely by the claims. In the drawings, like reference numerals designate identical or corresponding parts throughout the several views.

Hereinafter, the structure of the wearing article 1 according to embodiment 1 of the present invention will be described with reference to the drawings.

Fig. 1 to 6 show example 1.

As shown in fig. 1 and 2, the wearing article 1 of embodiment 1 has a bilaterally symmetrical shape and structure, and includes an absorbent main body 2 and a pair of waist portions 3. The absorbent main body 2 has: a waist portion extending in the girth direction X so as to cover the front waist of the wearer, a waist portion extending in the girth direction X so as to cover the rear waist of the wearer, and a crotch portion 22 covering the crotch between the waist portions.

The crotch portion 22 extends in a longitudinal direction Y orthogonal to the girth direction X. The absorbent main body 2 constitutes a part or the whole of the crotch portion 22.

As shown in fig. 1, in the finished product, the crotch portion 22 is folded in half on a line parallel to the girth direction X. Thereby, the end portions E3 in the girth direction X of the pair of girth members 3 in fig. 2 overlap each other as shown in fig. 1. The wearing article may be of the pants type, and the ends in the girth direction X of the front waistline portion 3 and the back waistline portion 3 may be welded to each other.

An absorbent core, not shown, is provided in the absorbent main body 2 of fig. 2. The absorbent core absorbs bodily fluids. The absorbent core is sandwiched between the topsheet and the backsheet. The sheets and the absorbent core are laminated to each other.

The top sheet is composed of a liquid-permeable thin nonwoven fabric and covers the skin surface of the absorbent core. A rib port not shown may be provided in the top sheet.

The back sheet covers the non-skin surface of the absorbent core and is made of a liquid-impermeable resin sheet. The waist portions 3 are bonded to the respective ends of the absorbent body 2 in the longitudinal direction Y.

Each waist portion 3 protrudes from the absorbent body 2 in the waist circumferential direction X. That is, the waist portion 3 protrudes in the waist-surrounding direction X from the crotch portion 22 and extends in the waist-surrounding direction X from both edge portions (end portions in the waist-surrounding direction) E2 of the absorbent main body 2.

The elastic members 32 for attaching the wearing article 1 to the wearer are provided in the waist portions 3, and for example, a plurality of elastic threads, elastic bands, or materials containing thermoplastic resins may be used as the elastic members 32, and the elastic members 32 may be deactivated (in a state of not having a contractive force) at the waist portion of the absorbent main body 2, that is, at the attachment regions α 3.

The absorbent main body 2 may be formed with leg hole portions fastened along the legs of the wearer. Another elastic member, for example, an elastic thread or the like, may be provided along the periphery of the leg of the wearer at the leg hole portions and the portions of the waist portion 3 connected to the leg hole portions.

The absorbent body 2 is attached to the skin surface of the waist portion 3.

In the present specification, the "skin surface" refers to a surface facing the skin of the wearer when the article 1 is worn, and the "non-skin surface" refers to a surface opposite to the skin surface.

Next, the present wearing article 1 will be described in more detail.

In fig. 2, the front and rear waist portions 3 are each formed by sandwiching a plurality of elastic members 32 extending in the waist circumferential direction X between two nonwoven fabric sheets 31. The two sheets 31 are fusion-bonded to each other at a plurality of first bonding portions 4 marked with gray. In the case of the present embodiment, the plurality of first joined portions 4 do not overlap the elastic member 32, and the two sheets 31 joined to each other at the first joined portions 4 are wrinkled (shirred) by the contraction force of the elastic member 32.

The first bonding portions 4 are arranged in a matrix (in rows and columns) in the girth direction X and in the longitudinal direction Y orthogonal to the girth direction X. That is, in the case of the present embodiment, the plurality of first joining portions 4 are arranged intermittently in the girth direction X and intermittently between two elastic members 32 adjacent to each other among the plurality of elastic members 32 in the longitudinal direction Y.

The plurality of first joint portions 4 may overlap the elastic member 32.

As shown in fig. 1, the front and rear waist portions 3 are fusion-bonded to each other at a plurality of second bonding portions 5 marked with black. The second joining portions 5 are intermittently arranged at the end portions E3 in the girth direction X of the front and rear waist portions 3 in the longitudinal direction Y.

The rows of the first joint portions 4 and the second joint portions 5 extending in the girth direction X are arranged parallel to and apart from each other in the girth direction X.

The first joint portion 4 does not overlap with each of the second joint portions 5, and the first joint portion 4 does not contact with the second joint portions 5, and the row of the first joint portion 4 and the row of the second joint portions 5 are arranged adjacent to and parallel to each other. The respective columns of the first engaging portions 4 extending in the longitudinal direction Y are also arranged parallel to and apart from each other in the longitudinal direction Y. Therefore, the

joints

4 and 5 may be arranged in a lattice and matrix.

In fig. 2, the elastic member 32 is bonded to at least one of the two sheets 31 at the first bonded region α C and the second bonded region α C2 of each waist portion 3 with an adhesive CE, and the two sheets 31 are bonded to each other at the two bonded regions α C and α C2 with the adhesive CE.

The first adhesive region α C in fig. 1 extends along the longitudinal direction Y of each waist portion 3 between the plurality of first joined portions 4 and the plurality of second joined portions 5 adjacent to the plurality of second joined portions 5, that is, at the end E3, of the plurality of first joined portions 4, it is noted that in the developed state of the intermediate product shown in fig. 2, the portions 5 of the waist portions 3 shown by the white squares are not welded and joined.

The second adhesive region α C2 in fig. 2 extends in the longitudinal direction Y at a portion of the waistline portion 3 adjacent to or abutting the absorbent main body 2.

On the other hand, the pair of sheets 31 are not bonded to each other by the adhesive CE in the non-bonded region α N, the non-bonded region α N is a region including the plurality of second joint portions 5 and is adjacent to the bonded region α C, and an end E3 of the non-bonded region α N in the girth direction X of each girth portion 3 extends in the longitudinal direction Y.

The first joint 4 shown by gray and the second joint 5 shown by black of fig. 1 are formed in the same pattern as each other.

That is, the pitch P2 in the longitudinal direction Y of the second joint 5 intermittently arranged in the longitudinal direction Y of fig. 3B is equal (to the same degree) to the pitch P2 in the longitudinal direction Y of the first joint 4 intermittently arranged in the longitudinal direction Y. The shape and size of each second joint portion 5 of the plurality of second joint portions 5 are substantially the same as the shape and size of each first joint portion 4 of the plurality of first joint portions 4.

For example, the length L1 in the girth direction X of each of the first joining units 4 and the second joining units 5 is shorter than the length L2 in the longitudinal direction Y.

In fig. 1, the first joint portions 4 are disposed in a central region α 1 directly above a region α 3 of the waist portion 3 to which the absorbent body 2 is attached, and in end regions α 2 on both sides of a region α 3 of the waist portion 3 and the central region α 1, it should be noted that the attachment region α 3 may be disposed in plural or may not be disposed in the first joint portions 4.

A pitch P in the girth direction X of the first joint portions 4 adjacent to each other in the central region α 1 of fig. 3A is smaller than a pitch P1 in the girth direction X of the first joint portions 4 adjacent to each other in the end regions α 2 of fig. 3B and 3C.

The pitch P3 in the girth direction X of the first joint portion 4 and the second joint portion 5 adjacent to the plurality of second joint portions 5 in fig. 3B may be larger than the pitch P1 in the girth direction X of the first joint portions 4 in the end region α 2, or may be equal to (to the same degree as) the pitch P1.

Next, a method for manufacturing the clothing article 1 will be described.

As shown in fig. 4A and 4B, the continuous elastic members F extending in the conveying direction L are conveyed along the conveying direction L in a state stretched in the conveying direction L.

The nip roller 60 sandwiches the continuous elastic member F between two continuous sheets (for example, continuous nonwoven fabrics) W4 having a pair of side edges 4E extending in the conveyance direction L, and bonds the two continuous sheets W4 so as to overlap each other with the adhesive CE applied to the continuous sheet W4, thereby producing a continuous body 40.

The plurality of continuous sheets W4 are fusion-bonded to each other at the plurality of first bonding portions 4 intermittently along the conveyance direction L of fig. 5 and in a predetermined pattern between the plurality of continuous elastic members F by the seal roller 61. The fusion bonding may be heat sealing (thermal fusion bonding) or fusion bonding by ultrasonic energy.

The continuous body 40 is deactivated by cutting the continuous elastic member F with a roller 62 (fig. 4A) or the like at a portion that becomes the adhering region α 3, i.e., a region α 3 shown by a two-dot chain line in fig. 5, and the absorbent body 2 is attached to the deactivated adhering region α 3 in a subsequent step.

As shown in fig. 5, the continuous body 40 having the pair of side edge portions 4E is slit by a slitter (slitter)63 (fig. 4A) along the conveying direction L while being conveyed along the conveying direction L. Thus, the continuum 40 forms a pair of waistline continuum 40 forming front and rear waistline portions. After the slitting, the two waist circumferential continuations 40 are relatively moved in the longitudinal direction Y so as to be separated from each other in the longitudinal direction Y orthogonal to the conveyance direction L.

Then, while the pair of waist continuations 40 are conveyed substantially parallel to each other in the conveyance direction L, the absorbent bodies 2 are arranged (stretched) so that the absorbent bodies 2 straddle the pair of waist continuations 40 and overlap with the respective waist continuations 40 at a portion (attachment region α 3), thereby producing a continuous laminate W1.

Thereafter, as shown in fig. 6, the continuous laminate W1 is folded in two at the absorbent main body 2 so that the pair of waist circumferential continuations 40 overlap each other.

As shown in fig. 6, the pair of waist circumferential continuations 40 are fusion-bonded to each other in the same pattern as the predetermined pattern at the end E3 of the portion that becomes the front and rear waist portions 3 and at the second bonded portion 5 between the mutually adjacent first bonded portions 4 of the plurality of first bonded portions 4. The fusion bonding may be achieved by ultrasonic energy of the ultrasonic horn 64 in fig. 4A, or may be thermal fusion bonding.

As shown in fig. 3B, the fusion-bonding step is performed so that the pitch P2 in the longitudinal direction Y of the second bonded portion 5 is equal to the pitch P2 in the longitudinal direction Y of the first bonded portion 4.

The welding and joining step is performed so that the shape and size of each of the second joint portions 5 of the plurality of second joint portions 5 are substantially the same as the shape and size of each of the first joint portions 4 of the plurality of first joint portions 4.

As shown in fig. 3B, the secondary fusion-bonding is performed in the predetermined pattern in which the length L1 in the girth direction X of each of the first bonding unit 4 and the second bonding unit 5 is shorter than the length L2 in the orthogonal longitudinal direction Y.

The step of performing the fusion bonding is performed such that the elastic member 32 is sandwiched between the plurality of first joint portions 4 and the plurality of second joint portions 5 adjacent to the plurality of second joint portions 5 in the bonded region α C between the plurality of first joint portions 4 and the plurality of second joint portions 5, and the elastic member 32 is bonded to at least one of the two sheets 31 with the adhesive CE interposed therebetween, and the step of performing the fusion bonding is performed such that the plurality of second joint portions 5 are disposed in the non-bonded region α N adjacent to the bonded region α C.

The step of creating the continuous body 40 and the step of fusion-bonding are performed such that the second bonding portions 5 do not overlap the first bonding portions 4, the second bonding portions 5 do not contact the first bonding portions 4, and the rows of the second bonding portions 5 and the rows of the first bonding portions 4 are arranged adjacent to each other.

Then, the continuous layered body W1 of fig. 6 is cut into individual wearing articles 1 in size (unit) along a virtual cutting line CL2 indicated by a one-dot chain line. That is, the continuous layered body W1 is sequentially cut in the longitudinal direction Y between the absorbent main bodies 2 to sequentially produce the respective wearing articles 1. In this way, the pair of waist circumferential continuous bodies 40 are sequentially cut at the position that becomes the end E3 in the waist circumferential direction X of the wearing article 1 and between the two rows of second joining

portions

5, 5. In this way, each pants-type worn article 1 shown in fig. 1 was obtained.

FIG. 7 shows embodiment 2

In this figure, the pitch P in the girth direction X of the first joint portions 4 adjacent to each other in the central region α 1 is set to be the same as the pitch P1 in the girth direction X of the first joint portions 4 adjacent to each other in the end regions α 2.

As described above, the preferred embodiments have been described with reference to the drawings, but various changes and modifications within a scope apparent to those skilled in the art will be apparent from the description.

For example, the pitches P, P1 and P3 may be set to be approximately equal to each other. The wearing article may not have a rib top or the like. Further, the tension of the elastic member may be nullified at a portion other than the portion overlapping (lap) with the absorbent body in the waist member.

Accordingly, such changes and modifications are to be construed as being within the scope of the present invention as defined by the appended claims.

Industrial applicability

The present invention can be applied to pants-type wearing articles.
