Description

  The present invention relates to an absorbent article that can reduce labor, mental and economic burdens associated with urination treatment, and more particularly, an absorbent article provided with an absorbent pad such as a urine collection pad (incontinence pad) and a sanitary pad. It is about.

For example, as shown in FIG. 15, a dirty diaper with the body facing sideways is taken up by the care recipient, for example, as shown in FIG. Pulling from the bottom, then pulling in a new diaper and then putting it on, it is particularly hard work, and repeating it many times every day is a mentally hard work.
Moreover, since the whole diaper is exchanged even when a part of the diaper is soiled due to urination, there is a problem that not only the economic burden is large but also the amount of waste increases.

So, if you use an auxiliary absorbent or absorbent pad in the diaper and urinate, absorb it with the auxiliary absorbent so that only the auxiliary absorbent can be replaced. A diaper that has been developed only when it is dirty has also been developed.
However, simply placing the auxiliary absorbent on the inner surface side of the diaper requires that the diaper be removed once and the dirty auxiliary absorbent is taken out for replacement, which is more economical than replacing the entire diaper. Although it is advantageous, the labor or mental burden required for the exchange is not particularly reduced, and the problem cannot be solved completely.

  Therefore, in order to solve this problem, a configuration in which an opening is provided in the center of the front of the disposable pants so that only the auxiliary absorbent body can be replaced without removing the diaper, and the opening is covered with an openable / closable sheet-like lid member In addition, replacement of the auxiliary absorber has been developed by opening the lid member and taking out the dirty auxiliary absorber from the opening of the diaper body so that an unused one can be placed in the diaper (patent) Reference 1).

  In addition, an aperture (opening) is formed in the front or rear panel of the diaper, and a pocket is fixed to the rear sheet (back sheet) containing a plurality of panel members (auxiliary absorbers) in the aperture, and absorbed by the central part of the diaper. Each panel member pulls one panel member saturated with body fluid from the pocket one by one from the pocket and exposes unused panel members instead. What is made to do is also known (refer patent document 2).

  Furthermore, in order to make it easier to replace the auxiliary absorber, there has been proposed an external absorber that is not provided in the diaper (Patent Document 3). This is composed of a front body A, a backward B, and a crotch C positioned between the two, and in the disposable pants having a structure in which the front A and the back B are joined to each other on both sides, A crotch opening is provided, and an absorbent pad that is detachably attached to the pant body is provided so as to close the crotch opening from the outside. In this configuration, the first engaging portions on the left and right side portions provided on the inner surface of the crotch opening of the pant body are engaged and fixed to the outer surface side of the absorbent pad.

  Similarly, the auxiliary absorbent body is externally configured by a pants-type auxiliary tool having an absorbent pad detachably attached to the main body of the pants and an exterior absorbent portion serving as an auxiliary absorbent body. The device is provided with an absorbent body partially formed with a liquid passing part, and the exterior absorbent part is attached to the outer surface side of the auxiliary tool to stably transfer the liquid to the exterior absorbent part. When urination occurs, it is removed from the pants-type assisting device and replaced. (See Patent Document 4)

However, in the disposable pants described in Patent Document 1, since the crotch is narrow in the first place, it is not easy to replace the auxiliary absorbent body by putting it in and out of the diaper. It is also difficult.
Moreover, in the diaper (absorbent article) described in Patent Document 2, the panel member that has absorbed urine can be replaced with an unused panel member by simply pulling it out from the pocket one by one. There is no need to set the auxiliary absorbent body in the diaper each time. However, it is a structure for fixing the pocket containing the panel member (auxiliary absorber) to the rear seat of the abdominal part or the dorsal part, and there is no panel member (auxiliary absorber) in the crotch part, There is a risk of urine leaking from the crotch area.

  Furthermore, the diaper described in Patent Document 3 has the auxiliary absorbent body attached from the outside, but the crotch is narrow, and a part of the auxiliary absorbent body is put into the opening at the time of attachment, so that the attachment is difficult. Moreover, even if it attaches, not only the periphery of an opening part gets wet but it becomes unsanitary, but there also exists a problem that urine may ooze out from the clearance gap between opening parts. Further, when the urine collecting pad is attached from the outside, there is a problem that the crotch portion is easily twisted because of slipping due to friction with clothes.

The diaper (absorbent article) described in Patent Document 4 is easy to replace because the outer absorbent part is attached from the outside of the auxiliary tool, but urine is absorbed by the outer absorbent part through the absorbent body of the auxiliary tool. Even if the exterior absorbent member is replaced, the absorbent body remains in a state where urine remains attached, and there is a problem that it becomes unsanitary.
Further, when urination occurs, both the absorbent body of the auxiliary tool and the exterior absorbent section become wet, and both of them must be exchanged, which is uneconomical.

The crotch part C is located between the part B and the crotch part C which is located at the wearer's crotch part. The both side parts of the abdominal part A and the back part B are joined to each other by joining means. A waist opening and a pair of leg openings are formed. As for the crotch part C, the both side edge part comprises the opening edge part 24 of the said leg opening part, and the opening part 22 is formed in the longitudinal direction substantially center.

  As shown in FIG. 2B, the ventral portion A, the dorsal portion B, and the crotch portion C are each provided with a liquid-permeable top sheet 25, a liquid-impermeable back sheet 26, and a liquid retaining property interposed between both sheets. The absorber 28 is provided. Here, the top sheet 25 and the back sheet 26 are joined to each other at the periphery of the absorber 28, and the absorber 28 is sandwiched and fixed between the top sheet and the back sheet.

  The urine absorbing pad 30 has a substantially rectangular shape in plan view, and is composed of an absorbent body sandwiched between the top sheet, the back sheet, and both sheets, as described in the following.

FIG. 3 is a plan view showing an embodiment of the urine collecting pad 30.
In the drawing, the urine collecting pad 30 is formed in a urine collecting pad main body 32 whose upper and lower ends are rounded in a substantially rectangular shape, and on the left and right sides of the central portion of the urine collecting pad main body 32 in the longitudinal direction. The mounting wing 34 is integrally formed with a length of more than half of the length.
The urine removing pad main body 32 is provided with attachment portions 39 at least at both end edges in the longitudinal direction so that the urine collecting pad 30 can be attached to the outer surface of the back sheet 26 when the urine collecting pad 30 is attached to the disposable diaper main body 20. At both left and right end portions, attachment portions 38 for attachment to the inner surface side of the diaper main body 20 are formed.

4A to 4D are diagrams schematically showing a typical cross-sectional configuration of the urine collecting pad main body 32 along the line XX in FIG. 3.
As is apparent from these drawings, the urine absorption pad body 32 includes a liquid-permeable top sheet 35, a liquid-impermeable back sheet 36, and an absorber 37 disposed between the top sheet 35 and the back sheet 36. Specifically, as shown in FIG. 5, the absorber 37 formed by wrapping the absorbent 37 a with a mount 37 b made of thin paper, for example, is sealed with a top sheet 35 and a back sheet 36 so as not to lose its shape. The top sheet 35, the back sheet 36, and the absorber 37 are liquid permeable top sheets, liquid impervious materials used in absorbent articles such as conventional disposable diapers and sanitary napkins. The back sheet and the absorbent body can be used as they are.

  The mounting wing 34 can be formed by extending the top sheet 35 and the back sheet 36, but is not limited thereto, and is formed by extending only the top sheet 35 or the back sheet 36, or A separately formed wing 34 may be integrated with the pad main body 32 by bonding with an adhesive or the like.

Here, in the urine collecting pad 30 of the first embodiment shown in FIG. 4A, the wing 34 is attached to the left and right ends of the surface sheet 35 arranged on the same surface side as the liquid absorbing surface of the urine collecting pad 30. As the portion 38, for example, an adhesive layer 38a such as a pressure-sensitive adhesive is formed.
In the urine absorbing pad 30 of the second embodiment shown in FIG. 4B, instead of the adhesive layer 38a of the urine absorbing pad 30 shown in FIG. 4A, a joining means 38b made of, for example, a mechanical fastener (surface fastener) made of a hook or a loop is provided. It is provided, and it engages with a hook-and-loop fastener described later on the disposable diaper main body provided corresponding thereto.

In the urine collecting pad 30 of the third embodiment shown in FIG. 4C, adhesive layers 38a as attachment means are also formed on the surface sheets 35 on both sides of the main body 32 of the urine collecting pad 30 shown in FIG. 4A. Other configurations are the same as those shown in FIG. 4A.
FIG. 4D shows the surface sheet 35 on both sides of the main body 32 of the urine absorbing pad 30 shown in FIG. 4A provided with hook-and-loop fasteners 39b, and the other configurations are the same as those shown in FIG. 4A.
In addition, the combination of an adhesion layer and a hook_and_loop | surface fastener is arbitrary, and is not restricted to the said embodiment.

FIG. 6 is a view schematically showing a disposable diaper in a state in which the urine absorbing pad 30 having such a structure is mounted. FIG. 6A is a front view thereof, FIG. 6B is a bottom view, and FIG. It is a figure for doing. Although not shown in FIG. 6C, in practice, a hot melt adhesive is applied between the sheet 25 and the sheet 26 over substantially the entire surface, and the elastic member 12 is also fixed together.
The urine absorbing pad 30 is shown in FIG. 4D as an example as shown in the figure, and is applied from the outside of the disposable diaper body 20 so as to cover the opening 22 formed in the crotch part C of the disposable diaper body 20. The hook-and-loop fastener 39b of the attachment means 39 provided on the top sheet 35 of the pad main body 32 is engaged with the hook-and-loop fastener 29 provided on the outer surface of the back sheet 26 of the disposable diaper main body 20 correspondingly.
Further, the wing 34 is folded inward from the leg opening portion CL of the disposable diaper main body 20 as shown by an arrow T (FIG. 6B) and placed in the disposable diaper main body 20, and the adhesive layer 38 a provided on the edge of the wing 34 is disposable. It is applied to the surface of the surface sheet 25 inside the diaper body 20 and lightly pressed to join the surface, and the attachment of the urine collecting pad 30 to the diaper body 20 is completed.

  In this way, by attaching the urine collecting pad 30 to the disposable diaper main body 20, the urine collecting pad is firmly fixed to the disposable diaper main body 20, and does not slip or twist, and the edge of the opening 22 Leakage from the part can be completely prevented. Further, when replacing the urine removing pad 30, the wing 34 can be easily removed by simply peeling it off from the top sheet 25 and the back sheet 26 inside the disposable diaper main body 20.

7 is a view similar to FIG. 6 showing a disposable diaper body 20 according to another embodiment of the urine absorbing pad, FIG. 7A is a front view thereof, FIG. 7B is a bottom view thereof, and FIG. 7C is a sectional view thereof. It is a figure for doing.
In the disposable diaper main body 20, a center sheet 20c having a width wider than the lateral width of the urine collecting pad 30 is provided over the entire length in the longitudinal direction over the entire longitudinal direction.
The center sheet 20c has an opening 20d that is substantially equal to or larger than the opening 22 of the disposable diaper body 20, and is disposed at a predetermined distance from the end in the width direction. A bonding portion 21 bonded to the outer surface by any means such as an adhesive is provided, and a mounting surface of the absorbent pad wing 34 having a width of the predetermined distance is provided.
The adhesive used for the joining portion 21 is preferably formed so as to be thick and easy to insert and fix the flap 34 and to cover the entire width of the fastener 29. Further, the center sheet 20c does not necessarily have to be attached over the entire length of the diaper body 20 in the longitudinal direction, and may be any length as long as the urine removing pad 30 can be attached.

The urine removing pad 30 is abutted from the outside of the disposable diaper main body 20 so as to cover the openings 22 and 20d formed in the crotch part C of the disposable diaper main body 20 in the same manner as in the first embodiment. The hook-and-loop fastener 39b provided on the surface sheet 35 of the main body 32 of the pad 30 is engaged with the hook-and-loop fastener 29 provided on the outer surface of the center sheet 20c, and the end of the wing 34 is the end of the center sheet 20c of the disposable diaper main body 20. Folded inward as indicated by arrow T (FIG. 7B), inserted between the center sheet 20c and the outer surface of the back sheet 36 of the disposable diaper main body 20, and a pressure sensitive adhesive 38a provided along the edge of the wing 34 Is bonded to the back surface of the center sheet 20c.
Note that the center fastener 20c and the hook-and-loop fastener 29 provided on the outer surface are preferably provided at a position overlapping the joint portion 21 in that it can be easily attached and detached. In addition, the wing attachment portion 38 may be at any position where the folded wing portion can be fixed, and thus may be a portion other than the end portion.
In this embodiment, since the wearer does not directly contact the wing 34 of the urine collecting pad 30, a natural wearing feeling of the diaper can be obtained without being conscious of the urine collecting pad 30.

FIG. 8 shows a second embodiment of the urine collection pad.
The urine collecting pad 30 'includes a wing (flap) 32' having elasticity over the entire side surface, and the wing 34 'includes, for example, an elastic member 34'a in an expanded state as the wing 34'. Gather 34'b is formed by arranging along, and the elasticity is provided. Other configurations are substantially the same as those of the first embodiment. By making the wings stretchable, it fits well in the disposable diaper main body 20 or the center sheet 20c, and since it is more integrated, it does not come off or shift in a sense of illusion, and a natural wearing feeling is obtained. In addition, by adjusting the width of the wing 34 'of the urine collecting pad 30' according to the second embodiment, it is naturally possible to attach it to the disposable diaper main body 20 of the first embodiment.

FIG. 9 shows a third embodiment of the urine absorbing pad.
In the urine collecting pad 30 ″, the wing 34 ″ is divided into a plurality of small wings 34 ″ C, and an attachment portion made of an adhesive layer or a hook-and-loop fastener is formed at the side end of each wing 34 ″ C. Other configurations are the same as those of the first embodiment. Since this urine removing pad 30 ″ has finely divided wings 34 ″ C, it takes time to fasten the wings 34 ″ C one by one. However, the wings 34 ″ C can be finely attached, and disposable diapers Since it is easy to follow the external shape of the attachment portion, there is an advantage that attachment is easy and, for example, even if a part of the wings 34 ″ C is removed, stable fixation can be achieved.
In addition, as the shape of the wing, a shape other than the above-described ones such as a substantially circular shape or an elliptical shape can be arbitrarily selected in a state where the pad is opened with the wing opened.

Next, the replacement sign function provided in the disposable diaper described above will be described.
This disposable diaper displays that the excrement such as urine is absorbed by the urine collecting pad and it is time to replace it.
The replacement time display means is known or known per se, and for example, the configuration disclosed by the present applicant in Japanese Patent Application Laid-Open No. 11-4852 can be used. That is, using an acidic composition and a color change indicator that changes color due to a change in pH, a sheet material containing a water-soluble compound that exhibits alkalinity when melted in water is used for the back sheet 36 of the urine removing pad 30. The water-soluble compound in the sheet material and water come into contact with each other to become alkaline, and the water comes into contact with the hydrophilic composition to change the color of the hydrophilic composition. The replacement time can be displayed. At this time, the hydrophilic material may be directly applied to the sheet material, or a hydrophilic sheet may be interposed between the sheet material and the hydrophilic material.

Thus, by giving a replacement sign function to the urine collection pad, when the urine collection pad absorbs urine or body fluid more than a predetermined amount, the change in the color of the replacement sign can be visually observed. Can know when to replace.
Although only the elastic member 12 for leg gathers is shown in FIGS. 6C and 7C as the outer package, a three-dimensional gather may be separately formed in order to prevent leakage from the legs. In this case, it is preferable that the wing of the absorbent pad has a length that does not cover the three-dimensional gather. Further, even when a center sheet is used, a three-dimensional gather can be formed in the same manner. In this case, the wing of the absorbent pad has an advantage of not hindering the effect of the three-dimensional gather.
The center sheet may not be formed from a single sheet, and is formed by combining two sheets to form an opening, the two sheets are separated, and the opening is cut into an opening. It may be. In addition, even if the hook-and-loop pad is not attached to the absorbent pad, the hook-and-loop material attached to the diaper body only needs to be a hook material. It can be used, and has the advantage of being gentle on the skin.

Next, a method for manufacturing the disposable diaper main body 20 described above will be described.
The disposable diaper main body 20 can be basically manufactured by a conventional method described in, for example, Japanese Patent Laid-Open No. 6-121811. In addition, the component part common to the disposable diaper main body 20 of the urine picking pad 30 can be manufactured by the same method as the disposable diaper main body.
That is, FIG. 10 shows a cutting process for continuously cutting, for example, a polyethylene web 45 to form strips to be a top sheet and a back sheet. In this step, the continuous polyethylene web 45 is cut into strips 45a and 45b serving as surface sheets with a cutter roll 46 provided with a cutting edge 48 that protrudes facing the anvil roll 50. At that time, the shape of the cutting edge 48 is, as shown in FIG. 9, for example, such that one side of the wings 34 formed on both side surfaces of the urine collection pad 30 is formed in the strips 45a and 45b. It is formed by a cutting pattern on the roll 46 so as to be a trapezoidal shape or a periodic shape such as a sine wave (not shown).

  FIG. 11 shows a process of reassembling the strips 45a and 45b cut in the cutting process to form a composite web. Here, one strip 45a of the cut strip is moved above the conveyor surface with respect to the other strip 45b by the arrangement of the rolls 52, 54, 56 and 58. At the same time, as shown in FIG. 12, when the strip 45a is moved laterally, across the strip 45b in plan view, and when the strip 45a is lowered to the conveyor surface and brought into contact with the other strip 45b, both strips The straight ends opposite to the cut ends of 45a and 45b are adjacent to each other, and the lateral movement of the strip 45b is controlled so that the strips partially overlap each other. Further, the positional deviation of the half-cycles 34 and 34 formed on the strips 45a and 45b is controlled by the difference in the moving distance between the strip 45a and the strip 45b.

  In FIG. 11 again, the adhesive spray nozzle 60 applies the adhesive to the end portion where the strip 45a and the strip 45b overlap. Under the roll 58, there is a backing roll 61, which forms a nip and presses the adhesive at the overlapping portions of the strips 45a and 45b to bring them into intimate contact for strong bonding. Alternatively, instead of the adhesive, the strips 45a and 45b can be thermally bonded with a heating roll.

FIG. 13 shows the assembly process. The cutting roll 72 is used to form the opening 22 in the composite web.
Here, the web-shaped top sheet (composite web) F2 made of the liquid permeable material of the same shape is overlapped with the web-shaped back sheet (composite web) F1 made of the liquid-impermeable material. . Thereafter, the top sheet and the back sheet are joined by pressing between the heated rotary seal rolls 70. Thereafter, the opening 22 is formed while the cutting roll 72 is rotated.

The sealing step shown in FIG. 14 is located downstream of the assembly step and seals the composite webs F1 and F2 around the opening 22 to form a continuous laminated sealing web F3.
Bonding between the composite webs F1 and F2 can be performed by an adhesive between the assembly process and the sealing process (not shown) or by thermal bonding.

  In this way, the sealing web F3 is then formed in a substantially central portion where the opening 22 is formed, and the sealing web F3 is adjacent to the opening 22 adjacent by a suitable means such as a cutting roll along the longitudinal direction. The disposable diaper main body 20 can be obtained by cutting between.

  In the above steps, the absorber 24 may be sandwiched and joined between the back sheet and the top sheet at the peripheral edge of the opening 22 or substantially the entire surface. In this case, by providing the disposable diaper body itself with absorbency, the absorbent article that is insufficient for the urine absorbing pad can be secured as the absorbent article.

  Although the manufacturing method of the disposable diaper main body demonstrated above is a case of what is called a trimless, as a method other than that, it is a matter of course that the manufacturing method which combined two sheets of right and left in the center part, and then removed the leg part may be sufficient.
