Description

  The present invention relates to a tape-type disposable diaper. More specifically, in the state where the diaper is addressed to the wearer, the position of the three-dimensional gather can be adjusted so that the three-dimensional gather functions effectively, and urine leakage from the diaper can be effectively prevented. The present invention relates to a tape-type disposable diaper.

  In recent years, as a diaper for infants or elderly people / handicapped persons, for example, a tape-type disposable diaper 100 shown in FIG. 9 is composed of respective parts of a front body 2, a crotch part 4 and a back body 6, and an absorbent body. 22, disposed so as to cover the surface of the absorber 22, at least a part of the top sheet 18 made of a liquid permeable material, and disposed so as to cover the back surface of the absorber 22, a liquid impermeable material A disposable diaper having a fastening tape 11 and a fixing tape 11 for fixing the back body 20 and the back body 6 disposed on the back body 6 side is widely used. Such a tape-type disposable diaper 100 can be worn by fastening each fastening tape 11 to the fastening region 13 disposed in the front body 2 of the diaper via the side of the wearer. it can.

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

  The above-described three-dimensional gather 26 is a member for preventing leakage of the urine excreted by the wearer, and is a leak-proof wall configured to be able to stand up three-dimensionally. In FIG. 9, it forms by folding back the side seat | sheet 19 arrange | positioned on the surface of the side flap of a diaper. By arranging such a three-dimensional gather 26, it is said that leakage from a leg opening or the like of the diaper (so-called “lateral leakage”) can be prevented.

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

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

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

  The present invention provides a three-dimensional gather so that the three-dimensional gather arranged around the absorber functions effectively in a state where the diaper is addressed to the wearer, that is, an appropriate arrangement position of the three-dimensional gather. It is possible to provide a tape-type disposable diaper capable of adjusting the position of the diaper and effectively preventing leakage of urine from the diaper.

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

  In the tape-type disposable diaper of the present invention, as described so far, at least the fixed ends of the pair of fastening tapes are fixed to the at least one pair of three-dimensional gathers, and the fastening tape is fastened. By performing the operation of fastening to the area, the position of the three-dimensional gather can be adjusted so that the three-dimensional gather functions effectively in the state where the diaper is addressed to the wearer, and the urine leakage from the diaper is effectively prevented. Can be prevented.

  The structure of a three-dimensional gather can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, as in the disposable diaper 1A shown in FIGS. 1A and 1B, an elastic material (a three-dimensional gather elastic material 36 (36a, 36b) is sandwiched and fixed between layers of the water-repellent sheet 32 (32a, 32b), and the three-dimensional gather It is possible to suitably use a material in which a gather is formed by the contraction force of the stretchable material 36. The three-dimensional gathered stretchable material 36 can be sandwiched and fixed, for example, at a folded portion of the water-repellent sheet 32.

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

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

  For example, when the three-dimensional gather is a Z-fold gather, as shown in FIG. 7, the fixed ends 11x and 11y of the fastening tapes 11a and 11b are placed near the Z-folded portions of the three-dimensional gathers 26a and 26b (that is, By fixing to the left and right side edges of the absorbent body 22 (in the vicinity of the bent portion), the three-dimensional gathers 26a and 26b can be favorably spread to the left and right.

  Here, FIG. 7 is sectional drawing which shows other embodiment (1G of tape type disposable diapers) of the tape type disposable diaper of this invention. Note that the cross section shown in FIG. 7 is a cross section at the same position as the cross section shown in FIG. 1B. In addition, in FIG. 7, about the thing comprised similarly to each element of the disposable diaper 1A shown to FIG. 1A, the same code | symbol is attached | subjected and description is abbreviate | omitted.

[2-3] Fastening area:
A fastening area | region is an area | region for fastening the fastening member arrange | positioned at the fastening tape, and is arrange | positioned at the front body of a diaper. For example, in the tape-type disposable diaper 1A shown in FIG. 1A, a hook material 46a is provided near the tip of the fastening tape 11, and the front body 2 of the diaper is made of a loop material 46b as the fastening region 13. A front patch 13a is attached. By fixing the fastening tape 11 (more specifically, the hook material 46a of the fastening tape 11) to the fastening region 13 (front patch 13a), the opening around the waist of the diaper and the leg A surrounding opening is formed and a diaper can be worn.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

[3-5] Application target:
The application target of the tape-type disposable diaper of the present invention is not limited to the one-piece type tape-type disposable diaper described so far. For example, the tape-type disposable diaper may be applied to a two-piece type tape-type disposable diaper. it can.

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

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

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

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

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

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

  Next, the fastening tape 11 used for the tape type disposable diaper of this invention is produced. In the tape-type disposable diaper of the present invention, at least the fixed ends of the pair of fastening tapes 11a, 11b are fixed to the three-dimensional gathers 26a, 26b, and therefore at least than the fastening tape used in the conventional tape-type disposable diaper. The length of the base material which comprises a pair of fastening tape is formed long. That is, in the state where the fixed end of the fastening tape is fixed to the three-dimensional gather, the length of the fastening tape extending from the side edge of the back body is about the same as the length of the fastening tape of the conventional tape-type disposable diaper. A fastening tape is prepared so as to have a length.

  The fixed ends 11x and 11y of the fastening tapes 11a and 11b thus manufactured are connected (fixed) to part of the three-dimensional gathers 26a and 26b arranged on the corresponding side edges. Although there is no restriction | limiting in particular about the fixing method of the fixing tape 11 and the three-dimensional gather 26, For example, the adhesion | attachment using a hot-melt-adhesive agent and another adhesive agent with high fluidity may be sufficient, and heat sealing etc. Can be fixed by heat or ultrasonic welding.

  In addition, in addition to the fastening tapes 11a and 11b connected to the three-dimensional gathers 26a and 26b, when the fastening tape 11 that is not connected to the three-dimensional gathers 26a and 26b is further provided, the fastening used in the conventional tape-type disposable diaper. A fastening tape is produced by the same method as that for the tape, and the fastening tape is fixed to a portion corresponding to the side edge of the back body.

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

  The method for manufacturing a tape-type disposable diaper according to the present invention is not limited to the above-described method. For example, a ring-shaped inserted member 72 as shown in FIG. The fixed ends 11x and 11y may be fixed to the three-dimensional gathers 26a and 26b in a state where the fastening tapes 11a and 11b are inserted into the insertion member 72, or as shown in FIG. Even if the through-hole 78 is formed, the fastening tapes 11a and 11b are passed through the through-hole 78 from the outer surface of the diaper, and the fixed ends 11x and 11y of the fastening tapes 11a and 11b are fixed to the three-dimensional gathers 26a and 26b. Good. Further, a fastening tape connecting member 76 as shown in FIGS. 3A and 3B may be further arranged.

  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.

  EXAMPLES Hereinafter, although this invention is demonstrated concretely based on an Example, this invention is not limited to these Examples. However, the tape type disposable diaper of this invention includes all the tape type disposable diapers provided with the invention specific matter, and is not limited to the following examples.

[Example 1]
As a tape-type disposable diaper of Example 1, a tape-type disposable diaper 1A having a configuration as shown in FIGS. 1A and 1B was produced. This tape-type disposable diaper is a tape-type disposable diaper for adults. The length in the front-rear direction is 840 mm, and the width of the back body 6 (the length between the side edges 6a and 6b) is 630 mm.

  Two fastening tapes are arranged on each of the left and right side edges of the back body, and the fixed ends of the pair of fastening tapes on the crotch part side are fixed to a three-dimensional gather. The height of the three-dimensional gather was 50 mm, and the connection position of the fixed end of the fastening tape was 35 mm from the standing line of the three-dimensional gather. That is, the connection position of the fixed end is a position that is 70% of the height of the three-dimensional gather.

  As for the other pair of fastening tapes, hot melt adhesion from both the front and back surfaces of the fastening tape by sandwiching it between the side sheet and the back sheet at the side edge of the back body, similar to conventional disposable disposable diapers. Fixed directly by the agent. Each fastening tape is extended by 40 mm from the side edge of the back body of the diaper before use of the diaper. The width of the fastening tape was 35 mm.

  Further, in the tape-type disposable diaper of Example 1, a member to be inserted is disposed on the inner side surface of the diaper on the outer side edge of the absorber, and the crotch side is inserted into the gap formed by the member to be inserted. A pair of fastening tapes were inserted and extended outward in the width direction of the diaper. The inserted member was disposed at a position 30 mm from the side edge of each back body. The width of the member to be inserted (length in the insertion direction of the fastening tape) was 30 mm, and the length in the longitudinal direction of the diaper was 55 mm.

[Wearing test]
After the tape type disposable diaper of Example 1 was addressed to the wearer's back body side, the front body of the diaper was moved to the stomach side via the wearer's crotch. In this state, that is, the state before the fastening tape is fastened, the three-dimensional gather is crushed by the wearer's buttocks so as to cover the surface of the absorbent body, and the front of the absorbent body has been narrowed. .

  From such a state, pull the fastening tape extended from the side edge of the back of the diaper, and attach the hook material of the mechanical fastener attached to the tip of the fastening tape to the loop of the mechanical fastener attached to the front body. By performing the operation of fastening to the fastening area made of the material, the three-dimensional gather connected to the fastening tape (the fixed end of the fastening tape is fixed) is pulled in conjunction, and the three-dimensional gather is moved to the left and right of the absorber. I was able to spread it. Thus, the tape-type disposable diaper of the present invention can easily adjust the position of the three-dimensional gather after the diaper is addressed to the wearer, and effectively prevents urine leakage due to the collapse of the three-dimensional gather. It was something that could be done.

  Moreover, since the fixed end of the fastening tape is fixed to the three-dimensional gather, the tape-type disposable diaper of the present invention can take a large amount of adjustment for the proper fastening position, and improve the fit of the diaper. I was able to.
