Description

  The present invention relates to a fastening tape for fixing a front body and a back body of a diaper according to a wearer's body shape, a manufacturing method thereof, and a tape-type diaper provided with such a fastening tape. .

  In general, a tape-type diaper is, for example, like a tape-type diaper 100 shown in FIG. 1, arranged so as to cover the absorber 22 and the upper surface of the absorber 22, and at least a top made of a liquid-permeable material. The sheet 18 is disposed so as to cover the lower surface of the absorber 22 and includes a back sheet 20 made of a liquid-impermeable material, and includes a front body 2, a crotch 4, and a back body 6. The disposable diaper is further provided with a fastening tape 10 that is arranged so as to extend from the left and right side edges 6a, 6b of the back body 6, and for fixing the front body 2 and the back body 6 (for example, (See Patent Documents 1 and 2).

  According to such a tape-type diaper 100, the excrement of the wearer passes through the liquid-permeable portion of the top sheet 18 (the center sheet 18a in the figure) and is absorbed by the absorber 22, and usually the liquid Leakage to the outside is prevented by the back sheet 20 made of an impermeable material, and excrement can be held inside the diaper. Further, by fixing the front body 2 and the back body 6 of the diaper to each other with the fastening tape 10, there is also an advantage that the wearer can easily put on the diaper.

  By the way, conventionally, as a fastening system for a tape-type diaper, an adhesive fastener that is fixed by the adhesive force of an adhesive has been widely used. However, in recent years, a mechanical structure of a convex member (hook member) and a concave member (loop member) is used. Transition to mechanical fasteners (also referred to as planar fasteners) that are fixed by bonding is progressing. In addition, as a base material of the fastening tape, a plastic film has been conventionally used. However, in order to soften the contact with the wearer's skin, a cloth material such as a non-woven fabric has been increasingly used. .

  However, when a mechanical fastener is used as the fastening system and a cloth material is used as the base material of the fastening tape, the hook material 44a of the mechanical fastener is engaged with the base material 48 of the fastening tape 10 as shown in FIG. There was a case where it matched. In such a case, the wearer or caregiver is forced to perform a cumbersome operation of once peeling off the hook material 44a from the base material 48. Temporarily, the hook material 44a is attached to the base material 48 of the fastening tape 10. When used in the engaged state, the area used for the engagement of the hook member 44a is reduced, so that the engagement force of the mechanical fastener is reduced.

  In order to solve the above problems, for example, a non-engaging portion 52 that does not engage with the hook material 44a at the end of the hook material 44a of the fastening tape 10 as in the tape-type diaper 110 shown in FIG. A disposable diaper in which is formed has been proposed (see, for example, Patent Document 3).

JP 2004-141532 A JP 2004-24307 A JP 2005-319139 A

  If the disengagement part 52 which does not engage with the hook material 44a is formed in the edge part of the hook material 44a of the fastening tape 10 like the tape type diaper 110 shown in FIG. The effect of preventing the engagement between the hook material 44a of the mechanical fastener and the base material 48 of the fastening tape 10 is recognized as compared with that not having. However, the effect is not sufficiently satisfactory and still leaves room for improvement.

  As described above, at present, there is no disclosure of a measure that can effectively prevent the engagement between the hook material of the mechanical fastener and the base material of the fastening tape, and such a measure is eagerly desired. .

  In the fastening tape of the present invention, a disengagement portion that does not engage with the hook material of the mechanical fastener is formed in a region including the tip of the fastening portion of the fastening tape, or a predetermined area is provided in the fastening portion of the fastening tape. Since the striped non-engaging portion is formed, the engagement between the hook material of the mechanical fastener and the base material of the fastening tape can be effectively prevented.

  Hereinafter, the fastening tape of the present invention, the manufacturing method thereof, and the best mode for carrying out the tape-type diaper will be specifically described taking a one-piece type tape-type diaper as an example. However, the present invention broadly encompasses a fastening tape having the invention-specific matters, a manufacturing method thereof, and a tape-type diaper, and is not limited to the following embodiments.

  In the present specification, “tape-type diaper” means, as in the tape-type diaper 1 shown in FIG. 5, the absorbent body 22, the top sheet 18 at least partly made of a liquid-permeable material, and liquid-impermeable. A back sheet 20 made of material, and composed of a front body 2, a crotch 4 and a back body 6, and arranged so as to extend from the left and right side edges 6 a and 6 b of the back body 6. A disposable diaper further comprising a fastening tape 10 for fixing the back body 6 to the front body 2 is meant.

  The “one-piece type” is different from the two-piece type described later in that it includes a top sheet, a back sheet, and an absorbent body. However, the absorbent body that absorbs and retains the gap between the top sheet and the back sheet. It means a type of diaper that is integrated (built-in) and configured integrally with a top sheet and / or a back sheet that has a mounting function.

  In addition, in this specification, “front body” means a part that covers the abdomen (front of the body) of the wearer when a diaper is worn on the wearer, and “inseam” means that the wearer wears a diaper. When the wearer wears a diaper, the part covering the inseam of the wearer means the part covering the back side (back of the body) of the wearer.

[1] Fastening tape:
The fastening tape of the present invention is a cloth base material 48 and a hook material of a mechanical fastener attached to the surface of the base material 48, like the fastening tape 10 provided in the tape-type diaper 1 shown in FIG. 44a, and the portion (pick portion 50) on the tape front end side with respect to the hook material 44a has a non-engagement portion 52 that is not engaged with the hook material 44a formed on the surface of the base material 48. The portion 52 is formed in a region including at least the tip of the knob portion 50 on the surface of the base material 48.

  As in the fastening tape 10 shown in FIG. 5, the non-engaging portion 52 is formed in a region including at least the tip of the knob portion 50 on the surface of the base material 48, so that the hook material 44 a of the mechanical fastener is fastened. The engagement of the tape 10 with the base material 48 can be effectively prevented. That is, since the non-engaging portion 52 is formed at the tip of the knob portion 50 of the base material 48 that is most easily engaged with the hook material 44a, the end of the hook material 44a is as in the tape-type diaper 110 shown in FIG. Compared with the case where the disengagement part 52 is formed in the part, the engagement between the hook material 44a of the mechanical fastener and the base material 48 of the fastening tape 10 can be effectively prevented.

  More specifically, for example, as shown in FIG. 6, when the non-engaging portion 52a is formed at the tip of the knob 50 (see (a) in the figure), the knob 50 is bent toward the hook member 44a. In such a case, the base material 48 and the hook member 44a do not engage at least in the region including the tip of the knob 50 (see (b) and (c) in the figure). Therefore, the engagement between the hook material 44a of the mechanical fastener and the base material 48 of the fastening tape 10 can be effectively prevented. Further, even if the base material 48 and the hook material 44a are engaged in the vicinity of the end portion of the hook material 44a, the tip of the knob 50 is not engaged with the hook material 44a and is lifted from the hook material 44a. The knob 50 can be easily peeled from the hook material 44a using the floating portion as a trigger.

  On the other hand, as shown in FIG. 4, if the non-engaging portion 52a is formed at the end of the hook member 44a, the base of the tip end region of the knob 50 is bent when the knob 50 is bent toward the hook member 44a. The material 48 and the hook material 44a are engaged (see (b) in the figure). Furthermore, since a floating portion that triggers peeling is not formed at the tip of the knob 50, it is difficult to peel the knob 50 from the hook material 44a.

  Moreover, when the non-engagement part 52 is formed in the knob | pick part 50 of the base material 48, the rigidity of the part will increase, it will become easy to pick the knob | pick part 50 of a fastener, and it will become difficult to bend. Therefore, the operation of attaching the hook material 44a of the mechanical fastener to the loop material 44b becomes extremely easy.

  A fastening tape is a tape-like member provided with a fastener for attaching a diaper to a wearer. For example, the fastening tape can be arranged so as to extend from the left and right side edges of the back body of the diaper so that the back body of the diaper can be fixed to the front body. Such a diaper can be made into a pants-type whole diaper by fixing the back of the diaper to the front with a fastening tape, allowing the wearer to wear the diaper. Become.

  As the fastening tape of the present invention, a tape made of a cloth base material and a hook material of a mechanical fastener attached to the surface of the base material is used. The present invention aims to effectively prevent the engagement between the hook material of the mechanical fastener and the base material of the fastening tape.

  In the fastening tape of the present invention, cloth is used as a material constituting the base material. In view of the effect of the present invention, that is, the effect of effectively preventing the engagement between the hook material of the mechanical fastener and the base material of the fastening tape, particularly when the base material is a material that can be engaged with the hook material. It is because the effect is demonstrated.

Specific examples of “cloth” include woven cloth, non-woven cloth, felt, and the like. Among these, a spunbonded nonwoven fabric is preferable because it is composed of long fibers and has high strength and can be manufactured at low cost. The spunbonded nonwoven fabric, it is preferable to use a material that basis weight of 40 to 120 g / ^{m 2,} it is more preferable to use those 50 to 100 g / ^{m 2.} By using a material having such a weight per unit area, the strength of the fastening tape can be improved, and an appropriate stiffness can be imparted. On the other hand, if a material having a basis weight of less than 40 g / m ² is used, the strength of the fastening tape becomes insufficient, and there is a possibility that the fastening tape may be broken when it is pulled strongly. Moreover, since the fastening tape will become too hard when the fabric weight exceeds 120 g / m ² , depending on the posture of the wearer, it may hit the wearer's skin and cause pain. Usually, in the case of a diaper for adults, a spunbond nonwoven fabric having a basis weight of about 70 g / m ² is used. In the case of a diaper for infants, a spunbond nonwoven fabric having a basis weight of about 80 to 100 g / m ² is used.

  Moreover, as a material which comprises cloth, a synthetic resin, for example, a polyethylene type, a polypropylene type, a polyamide type, a polyester type, a polyvinyl chloride type, a polystyrene type synthetic resin, etc. can be used conveniently.

  Moreover, in the fastening tape of this invention, the mechanical fastener (it is also called a planar fastener) which fixes by the mechanical coupling | bonding of a convex member (hook material) and a recessed part material (loop material) can be used suitably. . The mechanical fastener is, for example, a convex member (hook material) having a large number of protrusions (hook shape, mushroom shape, hook shape, etc.) formed on the surface, and a concave material (loop material) having loop-shaped fibers arranged on the surface. Often used in combination. In this fastener, the hook material is superimposed on the surface of the loop material, and a large number of protrusions of the hook material are engaged with the surface of the loop material, so that both members can be peeled and firmly fixed. It can be done.

  For example, the tape-type diaper 1 shown in FIG. 3 is an example in which the fastening tape 10 is attached so as to extend from the left and right side edges 6a, 6b of the back body 6 (more specifically, the side flap 8) of the diaper. It is. In this example, a double tape 28 having two strips 30 (30a, 30b) is used as the fastening tape 10, and a hook material 44a of a mechanical fastener is attached to the double tape 28 as a fastener 44. Has been. On the other hand, the front body 2 is provided with a front patch 12 made of a mechanical fastener loop material 44b as a fastener, so that the hook material 44a can be fixed. With such a configuration, the back body 6 of the diaper can be fixed to the front body 2, and the diaper can be worn by the wearer.

[1-1] First embodiment:
In the first embodiment of the fastening tape of the present invention, a disengagement portion is formed in a region including at least the tip of the knob on the surface of the base material. Here, the “surface of the base material” means the surface of the base material to which the hook material is attached. And, “the region including the tip of the knob” means that a disengagement portion is always formed at the most distal portion of the knob of the base material constituting the fastening tape. Even if the disengagement part is formed in the part, it is meant that the case where the disengagement part is not formed in the most distal portion of the knob is not included in the scope of the present invention.

  Since it is “at least the tip of the knob”, a non-engaging portion may be formed in a portion other than the tip of the knob. For example, in the tape-type diaper 1 shown in FIG. 5, the hook member 44a of the base material 48 and the back body 6 (more specifically, the disengagement part 52a is formed at the tip of the knob 50. Is an example in which a non-engaging portion 52b is further formed in a region between the side edges 6a and 6b of the side flap 8). On the contrary, the disengagement part 52 may be formed only in the knob | pick part 50 of the base material 48 like the tape type diaper 120 shown in FIG. 8, and the tape type diaper 130 shown in FIG.

  As a formation pattern of a non-engagement part, a pattern as shown in FIG. 7 can be mentioned, for example. The patterns (a) to (c) in FIG. 7 are obtained by forming the non-engaging portion 52a on the knob 50 on the surface of the base material 48 and then the hook material 44a of the base material 48 and the back body 6 (more specifically, Is an example in which a non-engaging portion 52b is further formed in a region between the side edges 6a and 6b of the side flap 8).

  The patterns (a) and (c) are examples in which the non-engaging portions 52a and 52b are formed so as to be in contact with the end portion of the hook material 44a. The pattern (b) is in contact with the end portion of the hook material 44a. This is an example in which the non-engaging portions 52a and 52b are formed so as not to occur. Among these patterns, the pattern (b) is preferable in that the rigidity of the region where the hook member 44a is disposed and the region in the vicinity thereof does not become excessively high. If the rigidity of the region where the hook member 44a is disposed or the region in the vicinity thereof is excessively increased, the hook member becomes difficult to follow the loop member, and a gap is likely to be generated between the hook member and the loop member. Therefore, the engaging force of the fastener may be reduced, and the fastener may be easily peeled off. Note that the tape-type diaper 1 shown in FIG. 5 is an example in which the non-engaging portions 52a and 52b are formed in the pattern (b).

  The pattern (c) is an example in which the disengagement portion 52b is formed up to the end located on the side edge 6a, 6b of the diaper back body 6 (more specifically, the side flap 8) of the base material 48. It is. The pattern (c) can also be manufactured by forming the non-engaging portion 52 on the entire surface of the base material 48 in advance, and then attaching the hook material 44 a from above the non-engaging portion 52. Therefore, the non-engaging portion 52 can be formed without considering the position of the hook member 44a. Moreover, if it is such a pattern, a non-engagement part can also be formed in the process of manufacturing a diaper, and the raw material which formed the non-engagement part previously can also be thrown into the manufacturing process of a diaper. Thus, the pattern (c) is preferable because it is easy to manufacture the fastening tape having the disengaged portion formed thereon.

  In the fastening tape of this invention, it is preferable that the non-engagement part is formed so that it may occupy the area of 40 area% or more with respect to the total area of a knob | pick part. By making the formation area of the non-engaging portion in such a range, the effect of effectively preventing the engagement between the hook material of the mechanical fastener and the base material of the fastening tape becomes more effective.

[1-2] Second embodiment:
In the second embodiment of the fastening tape of the present invention, the non-engaging portion is formed in a striped shape, and the striped non-engaging portion is defined by the outermost edges of the striped non-engaging portion. Is formed so as to occupy an area of 80% by area or more with respect to the total area of the region to be disengaged (non-engagement region), and the area of the non-engagement region is 40% by area or more with respect to the total area of the knob It occupies an area.

  When the non-engaging portion is formed in a striped pattern in this way, even if there is an engaging portion (a portion where the surface of the base material is exposed) between the non-engaging portion and the non-engaging portion, the surrounding non-engagement. Since the engaging force with the hook material is sufficiently reduced by the joint portion, the same effect as in the first embodiment can be obtained. Moreover, since the non-engagement part is divided and formed, the rigidity of the fastening tape can be reduced, and even when it hits the wearer, the feeling of wearing is hardly hindered. Furthermore, since the formation area of a non-engagement part is small, there exists an advantage that it can manufacture at low cost.

  For example, the pattern (d) in FIG. 7 is an example in which the non-engaging portions 52a and 52b are each divided into two strips to form striped (two) non-engaging portions. In the illustrated example, two disengagement portions are formed, but three or more disengagement portions may be formed. Moreover, in the example of illustration, although the width | variety of each non-engagement part is substantially equivalent, the width | variety of a non-engagement part may be the same, and may differ. However, from the viewpoint of effectively preventing the engagement between the hook member and the base material of the fastening tape, it is preferable that the engagement portion is narrower than the adjacent non-engagement portion.

  In the pattern (d), as in the pattern (b) in FIG. 7, non-engaging portions 52a and 52b are formed so as not to contact the end portion of the hook member 44a. Therefore, the pattern (d) also exhibits the same preferable effect as the pattern (b) in FIG. 7 that the rigidity of the area where the hook member 44a is arranged and the area in the vicinity thereof does not become excessively high.

  The “non-engagement region” referred to in this specification is a region defined by the outermost edges of the striped non-engagement portion. That is, it means a region including a non-engagement portion and an engagement portion existing therebetween. In the second embodiment, the striped disengagement portion is formed to occupy an area of 80 area% or more with respect to the total area of the disengagement region, and with respect to the total area of the knob portion, It is formed so that the area of the non-engaging region occupies an area of 40 area% or more.

  By setting the formation area of the disengagement region to 40 area% or more with respect to the total area of the knobs, the hook material of the mechanical fastener and the base material of the fastening tape can be engaged as in the first embodiment. The effect of preventing effectively is obtained. However, at this time, it is necessary that the total area of the non-engagement portions be formed so as to occupy an area of 80 area% or more with respect to the total area of the non-engagement region. Otherwise, even if the area of the non-engaging region is 40% by area or more with respect to the total area of the knobs, a sufficient effect cannot be obtained due to the influence of the engaging portions existing between the non-engaging portions. Because.

  Moreover, in 2nd Embodiment, it is preferable that the non-engagement area | region is formed in the area | region including the front-end | tip of a knob part at least among the surfaces of a base material. By adopting such a configuration, similarly to the first embodiment, even if the base material and the hook material a are engaged in the vicinity of the end portion of the hook material, the tip of the knob portion is hooked to the hook material. , And is lifted from the hook material, so that the knob can be easily peeled off from the hook material using the floating portion as a trigger.

  The disengagement part of the fastening tape can be formed by melting a part of the base material with heat or ultrasonic waves, or coating the surface of the base material with a resin film. However, the fastening tape of the present invention is preferably formed by resin coating the surface of the substrate. This method does not reduce the flexibility of the fastening tape and does not impair the texture of the fastening tape as compared to a method of melting a part of the base material or a method of coating the surface of the base material with a resin film. And can be suitably used in the present invention.

  On the other hand, the method of melting a part of a substrate with heat or ultrasonic waves is difficult to melt evenly in the diaper production line due to a change in the production rate. The joints tend to be non-uniform. Therefore, not only is it difficult to control during production, but the texture of the fastening tape may be impaired. In addition, the method of covering the surface of the base material with a resin film is that the region where the non-engagement portion is formed is clearly thicker than the other portions due to the resin film, and the tactile feel of the knob is deteriorated and worn. May cause discomfort to the people. Furthermore, in order to prevent the adhesive from protruding from the base material when the resin film is bonded to the base material, the adhesive cannot be applied to the end of the film. There is a possibility of causing a problem of drowning during use.

  When the surface of the substrate is covered with a resin film, the resin film may be bonded to the surface of the substrate using a hot melt adhesive or the like. The type of resin is not particularly limited, but it is preferable to use polypropylene, polyester or the like, and it is more preferable to use PET (polyethylene terephthalate).

  When the surface of the base material is resin-coated, a synthetic resin such as polyethylene, polypropylene, polyamide, polyester, polyvinyl chloride, or polystyrene based thermoplastic resin is heated and melted. You just apply to. In this case, it is preferable to use the same type of material as the base material because the affinity with the base material is improved and the base material and the resin coating layer can be firmly fixed. The above effect can be obtained by forming the resin coating layer using a resin material containing at least 25% by mass of the same resin as that constituting the substrate.

[2] Manufacturing method of fastening tape:
The fastening tape as described above can be manufactured, for example, by the following method. For example, as shown in FIG. 10 or 11, first, a long hook material 56 made of a hook material 44 a is attached to the surface of a base material sheet 54 made of a base material 48, and both side edges of the long hook material 56 are attached. A pair of strip-like non-engaging portions 52a and 52b is formed along the, and the fastening tape intermediate body 58 is formed.

  Next, in the region defined by the outermost edges 60 of the pair of non-engaging portions 52a and 52b of the fastening tape intermediate body 58, the region where the one non-engaging portion 52a is formed, the long hook material 56 In the order of the region where the non-engagement portion 52b is formed, the region where the long hook material 56 is attached, and the region where one non-engagement portion 52a is formed. The body 58 is continuously cut and divided into two. This cutting is not particularly limited as long as it is cut into a continuous shape, but it is usually preferable to cut into a periodic corrugated shape as shown in FIGS.

  Thereafter, the fastening tape intermediate body 58 cut into two pieces is cut into a desired shape of the fastening tape 10, so that a disengagement portion is formed in a region including at least the tip of the knob portion 50 on the surface of the base material 48. The fastening tape 10 in which 52 (52a, 52b) is formed can be obtained. When the fastening tape intermediate 58 is cut into a periodic corrugated shape as shown in FIGS. 10 and 11 and divided into two, the side edge of the base sheet 54 from the apex portion of the corrugated shape By cutting the fastening tape intermediate body 58 in a direction orthogonal to the fastening tape intermediate body 58, the fastening tape 10 having a shape as shown in FIG. 10 or FIG. 11 can be manufactured.

  According to the method as described above, a large number of fastening tapes can be produced simply and efficiently. The reason for cutting in the region defined by the outermost edges 60 of the pair of non-engaging portions 52a and 52b is to form the non-engaging portion in the region including the tip of the knob 50 of the fastening tape 10. It is to do.

  In the illustrated example, since the relatively narrow non-engagement portion 52 (52a, 52b) is formed, the cutting line passes through the vicinity of the outermost edge 60 of the non-engagement portion 52, but the relatively wide width. When the non-engaging part is formed or when the non-engaging part is formed on the entire surface of the base sheet, the cutting line does not necessarily have to pass near the outermost edge of the non-engaging part.

[3] Tape-type diaper The tape-type diaper of the present invention includes the above-described fastening tape of the present invention as the fastening tape. More specifically, the absorbent body is disposed so as to cover the upper surface of the absorbent body, and is disposed so as to cover at least a part of the liquid permeable material and the lower surface of the absorbent body. A back sheet made of a permeable material, and is composed of each part of the front body, the crotch part and the back body, and is arranged so as to extend from the left and right side edges of the back body, the front body and the back body The fastening tape is a tape-type diaper that is the fastening tape of the present invention.

[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.

  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. It is possible to use wood pulp or non-wood pulp defibrated as fluff pulp, sodium polyacrylate as SAP, tissue, absorbent paper, hydrophilized nonwoven fabric as hydrophilic sheet preferable.

  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 used together 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.

  It is preferable that the absorber is interposed at least in part between the top sheet and the back sheet. 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. Therefore, the flap part in which the absorber is not interposed is formed between the top sheet and the back sheet at the peripheral part of the absorber. The absorber is interposed in at least a part between the top sheet and the back sheet. More specifically, the absorbent body may be interposed at least in the crotch region, and the absorbent body may extend to the front body and the back.

  It is preferable that the absorber is entirely wrapped with 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.

  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 tape-type diaper 1 shown in FIG. 5 is an example in which an hourglass-type absorber is used as the absorber 22.

  In addition, a sheet (second sheet) for diffusing a liquid such as urine or body fluid may be incidentally disposed on the upper surface side of the absorber (for example, between the absorber and the top sheet). . When this second seat is attached, even if the space on the lower surface of the top sheet is not sufficiently formed due to the posture of the wearer, etc., the absorption rate of urine and body fluids 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, pulp, and composite fibers thereof. As the pulp, crimped fibers such as curly cellulose fibers can be suitably used.

[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 needs to absorb the wearer's urine. Usually, at least near the upper surface of the absorbent body, it is made of a liquid-permeable material capable of transmitting 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. For example, the form which comprises the top sheet arrange | positioned at the upper surface part of an absorber and the top sheet arrange | positioned at the part of a side flap with a different sheet | seat is also utilized frequently. In the tape-type diaper 1 shown in FIG. 5, a top sheet 18 (center sheet 18a) made of a liquid-permeable material is disposed at the center of the diaper, and the side flap 8 portion of the diaper is resistant to liquid permeation. It is the example which has arrange | positioned the top sheet 18 (side sheet 18b) which consists of ventilation water-repellent material which shows.

[3-3] Backsheet:
A back seat | sheet is a sheet | seat arrange | positioned so that the lower surface (surface located in a wearer's clothing side 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. Although there is no restriction | limiting in particular about the arrangement | positioning method, For example, the structure which arrange | positions the back seat | sheet 20 so that it may correspond with the external shape of a diaper like the tape-type diaper 1 shown in FIG. However, it is not always necessary to adopt such a configuration. From the viewpoint of preventing leakage of urine absorbed by the absorber, a back sheet made of a liquid-impermeable material is disposed at least in a portion where the absorber is present. May be.

  Examples of the liquid-impermeable material constituting the backsheet include a liquid-impermeable film made of a resin such as polyethylene. 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.

  Note that a sheet material (cover sheet) may be bonded to the outer surface 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] Solid gathering:
In order to prevent the side leakage of the urine excreted by the wearer, a three-dimensional gather may be provided. 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.

  The structure of a three-dimensional gather can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, a stretchable material (a three-dimensional gathered stretchable material) disposed on a part of the water-repellent sheet material and a sheet (gather) formed on the sheet material by the three-dimensional gathered stretchable material can be suitably used.

  The three-dimensional gather may be formed of a sheet material that is completely different from the top sheet and the back sheet, but may be formed by folding back a top sheet such as a center sheet or a side sheet. For example, the tape-type diaper 1 shown in FIG. 5 is an example in which the three-dimensional gather 26 (26a, 26b) is formed by folding back the side sheet 18b. However, the three-dimensional gather may be formed by folding back a member other than the top sheet such as a second sheet.

  In order to prevent leakage from the crotch part, this three-dimensional gather may be formed at least in the crotch part, but may be formed in the front body or the back body. For example, the tape-type diaper 1 shown in FIG. 3 has a pair of three-dimensional gathers 26 (26a, 26b) formed continuously from the crotch part 4 to both the front body 2 and the back body 6 along the longitudinal direction of the diaper. An example is shown. Further, at least one pair of solid gathers must be formed, but two or more pairs may be formed.

  The three-dimensional gather may be an inward gather that tilts toward the inside of the diaper, or may be an outward gather that tilts toward the outside of the diaper. Moreover, it can also be set as the three-dimensional gathers (C fold gather, Z fold gather, etc.) which formed the bending part and the folding | turning part in a part of height direction. For example, the tape-type diaper 1 shown in FIG. 5 is an example in which the three-dimensional gathers 26 (26a, 26b) are inwardly gathered.

[3-5] Various elastic materials:
In a tape-type diaper, 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. Further, when the leg stretchable material is disposed, the leg stretchable material contracts on both sides of the absorbent body when changing the diaper, so that the vicinity of the crotch portion is deformed into a bowl shape and a recess is formed. For this reason, urine and body fluid accumulate in the concave portion, and the diaper can be easily replaced without spilling urine and body fluid.

  For example, the tape-type diaper 1 shown in FIG. 5 is an example in which leg gathers are formed by arranging two leg-around elastic members 40 linearly along the longitudinal direction of the diaper. The leg-around elastic member 40 is made of rubber thread. However, the leg-surrounding elastic members are not necessarily arranged linearly, and may be arranged in a curved line along the curve of the leg-periphery opening, for example.

  The leg stretchable material is preferably formed with a leg stretchable material 40 in a portion outside the upright line 46 of the three-dimensional gather 26, for example, like a tape-type diaper 1 shown in FIG. 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.

  Note that the tape-type diaper 1 shown in FIG. 5 shows an example in which the shape, arrangement position, number of arrangements, and the like of the leg elastic members 40 are bilaterally symmetric. It is. And in the tape-type diaper 1 shown in FIG. 5, although the example in which the leg periphery elastic material 40 was arrange | positioned two on one side was shown, only one may be arrange | positioned and three or more may be arrange | positioned. Good. Further, when using a plurality of leg-surrounding stretchable materials, the thickness, stretch rate, etc. may be set as appropriate according to the purpose, and it is not necessary to use the same for all.

  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 addition, the tape-type diaper 1 shown in FIG. 5 is the example which has arrange | positioned the strip | belt-shaped waist circumference elastic material 42 along the edge of the back body 6 of a diaper. The belt-like waist elastic member 42 is made of an elastic foam such as 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., as well as thread rubber and flat rubber made of elastic materials such as natural rubber and synthetic rubber (urethane rubber, etc.). .

  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 natural rubber or synthetic rubber, it is preferably fixed in a stretched state of 100 to 400%, and more preferably fixed in a stretched state of 200 to 300%. By fixing in the extended state in such a range, a sufficient stretching force can be applied.

  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.

[4] Tape type diaper manufacturing method:
Hereinafter, the manufacturing method of the tape type diaper of this invention is demonstrated in the example in the case of manufacturing the tape type diaper 1 shown in FIG. First, the absorber 22 and the leg elastic member 40 wrapped in a hydrophilic sheet are placed on the upper surface of a long sheet material (back sheet material) that is a material of the back sheet 20, and the top sheet is further disposed on the upper surface. By placing a long sheet material (top sheet material) as 18 material, a laminate (diaper continuum) as an intermediate body of the diaper is obtained. At this time, as the top sheet material, two types of a top sheet material corresponding to the center sheet 18a and a top sheet material corresponding to the side sheet 18b are used. A three-dimensional gather 26 is formed by providing a folded portion on the sheet material corresponding to the side sheet 18b.

  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, a fastening tape in which a non-engaging portion 52 (52a, 52b) that does not engage with the hook material 44a is attached to a region including at least the tip of the knob 50 on the surface of the base material 48, and the diaper is continuous. A tape-type diaper 1 is produced by cutting the body into individual diapers.

  In addition to the method described above, a fastening tape is previously attached to the top sheet material, and the absorbent body and leg elastic members wrapped in the hydrophilic sheet are placed on the upper surface of the back sheet material, Furthermore, you may obtain a diaper continuous body by mounting the top sheet material to which the fastening tape was attached to the upper surface. 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 diaper becomes possible, which contributes to improvement of productivity.

[5] Applicable objects of the tape-type diaper of the present invention:
The application object of the tape-type diaper of the present invention is not limited to the one-piece type tape-type diaper, and can be applied to, for example, a two-piece type tape-type diaper. That is, even in a two-piece type tape-type diaper, the effect of the tape-type diaper of the present invention can be enjoyed by providing the fastening tape of the present invention.

  “Two-piece type” means an absorbent main body that functions to absorb and retain the excrement of the wearer (absorption / holding function) and an exterior member that functions to encapsulate the wearer's body (mounting function) And a diaper of the type in which an absorbent main body is disposed inside the exterior member.

  An absorptive main body is a member provided with an absorber, a top sheet, and a back sheet as constituent elements, and is manufactured by sandwiching the absorber between the top sheet and the back sheet and sealing the peripheral edge of the absorber. be able to. An absorptive main body is comprised by the size which covers at least the crotch part of a 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.

  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. In the two-piece type tape-type diaper, the absorbent main body fulfills the absorption / holding function to absorb and hold the excrement of the wearer, so a liquid-impermeable material is used as a material constituting the exterior member. There is no need to use. 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.

  Moreover, the application object of the tape type diaper of this invention is equipped with the double tape 28 provided with the two strip | belt-shaped bodies 30 (30a, 30b) as the fastening tape 10, like the tape type diaper 1 shown in FIG. It is not limited to the above, but also includes one having a single strip. Further, a double tape 32 provided with a single band 30 (30c) having two convex portions 34 (34a, 34b) as the fastening tape 10, such as the tape-type diaper 120 shown in FIG. It may be provided. Furthermore, like the tape-type diaper 130 shown in FIG. 9, the fastening tape 10 may be constituted by a part of the side flap 8. These fastening tapes may have a perforation in a part thereof so that they can be separated.

  Hereinafter, the fastening tape of the present invention will be described more specifically with reference to examples. However, these examples show some embodiments of the present invention, and the present invention should not be construed as being limited to these examples.

(Comparative Example 1)
A polypropylene spunpond nonwoven fabric with a basis weight of 70 g / m ² , a width of 50 mm and a length of 100 mm is used as a base material, and a hook material of a mechanical fastener with a width of 50 mm and a length of 24 mm (trade name: “Scotch Mark” hook) -Tape CS-600 (1600DH), manufactured by Sumitomo 3M Limited) was attached to form a fastening tape. At this time, as shown in FIG. 12 (a), the hook member 44a was arranged so that both end portions thereof were located at portions of 20 mm and 44 mm in length from the tip of the base material 48. That is, in this fastening tape 10, the knob portion 50 extends from the tip to a portion having a length of 20 mm. The fastening tape 10 in which the disengaged portion was not formed at all was used as the fastening tape of Comparative Example 1.

Example 1
An adhesive tape was attached to the entire surface of the knob portion 50 to cover the fastening tape 10 of Comparative Example 1, and a non-engagement portion 52a was formed on the entire surface (100 area%) of the knob portion 50. This fastening tape 10A was used as the fastening tape of Example 1.

(Examples 2 to 4, Comparative Example 2)
Except that a part of the surface of the knob is covered with an adhesive tape, a non-engaging part is formed in the knob in the same manner as in Example 1, and the fastening of Examples 2 to 4 and Comparative Example 2 I got a tape. Specifically, as shown in FIGS. 12B to 12E, the fastening tape 10B of Example 2 ((b) in the figure) has a length of up to 10 mm starting from the tip of the knob 50. The part, the fastening tape 10C of Example 3 ((c) in the figure) is a part up to a length of 8 mm starting from the tip of the knob 50, and the fastening tape 10D of Example 4 ((d) in the figure) is a knob. The portion up to a length of 6 mm starting from the tip of the portion 50, the fastening tape 10E of Comparative Example 2 ((e) in the figure) is 20 mm long from the tip of the knob 50 (10mm in length) A non-engaging portion 52a was formed in a portion up to the rear end) of the knob portion 50.

(Example 5)
Except that a part of the surface of the knob is covered with an adhesive tape in a striped manner, a non-engaging portion is formed in the knob in the same manner as in Example 1 to obtain the fastening tape of Example 5. It was. Specifically, as shown in FIG. 12 (f), a portion up to a length of 2 mm starting from the tip of the knob 50 and a length of 4 mm from the tip of the knob 50 up to a length of 6 mm. The non-engaging portions 52a are formed in the portions. That is, two disengaged portions were formed. This fastening tape 10F was used as the fastening tape of Example 5.

[Evaluation methods]
About the fastening tape of Examples 1-5 and Comparative Examples 1-2, the engaging force (ease of peeling) was evaluated by the following method.

  The tabs of the fastening tapes of the examples and comparative examples are bent so that the rear end (that is, the boundary line with the hook material) is a crease, and brought into contact with the hook material. Next, using a 500 g roller, the hook material and the fastening portion of the fastening tape are pressure-bonded under the condition of 5 mm / second and one reciprocation. Thereafter, the rear end portion of the fastening tape was held by hand, the contact portion between the hook material and the knob portion was played with a finger, and the number of times until the knob portion was peeled off from the hook material was counted. When the number of times is 0 to 1, “very good / ◎”, 2 to 5 times, “good / ◯”, 6 to 10 times, “usable / Δ”, more than 10 times, Evaluated as “bad / ×”. The results are shown in Table 1.

[Evaluation results]
The fastening tapes of Examples 1 to 5 showed a good result that the knob was peeled off from the hook material only by flipping the contact portion between the hook material and the knob with the finger 0 to 9 times. That is, in a tape type diaper using such a fastening tape, it was considered that the engagement between the hook material of the mechanical fastener and the base material of the fastening tape can be effectively prevented. Among them, the fastening tapes of Examples 1 to 3 showed a very good result that the knob part was peeled off from the hook material only by flipping the contact part between the hook material and the knob part with 0 to 1 finger. .

  On the other hand, since the fastening tape of Comparative Example 1 does not form any non-engagement portion, the fastening tape of Comparative Example 2 does not form the non-engagement portion at the tip of the knob, so both The drop was not sufficient, and even when the contact portion between the hook material and the knob portion was played ten times with a finger, the knob portion was not peeled off from the hook material. That is, in a tape-type diaper using such a fastening tape, it was considered that the hook material of the mechanical fastener and the base material of the fastening tape were likely to be engaged, and the separation was difficult.

  The tape-type diaper of the present invention can be suitably used as a diaper for infants or for adults such as elderly people and persons with disabilities who need care.
