Description

  The present invention, like a disposable diaper, comprises an absorbent body, a topsheet at least partly made of a liquid-permeable material, and arranged to cover the surface of the absorbent body, and a liquid-impermeable material. The present invention relates to a urine pad which is an absorbent article including a back sheet disposed so as to cover the back surface of the body.

  In recent years, a disposable diaper and a urine pad (also referred to as “inner pad”, “auxiliary pad”, etc.) have been used in combination in order to reduce labor when changing the diaper. For example, instead of placing the adult disposable diaper directly on the wearer's skin, a urine pad is laminated on the surface of the top sheet of the disposable diaper, and the disposable diaper with the urine pad laminated is worn by the wearer. Apply to the skin. By doing so, even when the wearer excretes, it is sufficient to replace only the urine pad, and the disposable diaper can be used as it is. Since such a method is easier to replace than a method of replacing the entire disposable diaper every time it is excreted, the caregiver's labor is reduced. Moreover, since a urine pad is cheaper than a disposable diaper, it is advantageous in terms of cost as compared with a method of exchanging the entire disposable diaper every time it is excreted.

  In general, a rectangular urine pad having a rectangular shape is used as the urine pad. For example, a rectangular flat urine collecting pad is disclosed in which a through hole is formed by making a cut in the center upper portion of the pad (see Patent Document 1).

Japanese Patent Laid-Open No. 11-216155

  The urine collection pad described in Patent Document 1 has a structure in which a through-hole is formed by cutting in the upper center of the plane of the pad, and has been devised to prevent leakage. However, a rectangular flat urine pad such as the urine collecting pad described in Patent Document 1 cannot be used for a person who is paralyzed or has a joint contracture (a state where the joint is hard and difficult to bend and stretch), or cannot lie on his back. There is a problem that it is difficult to put on a person who can only take a lateral posture. That is, a person with paralysis or joint contracture often has a narrow range of motion of the hip joint and cannot open the crotch widely. In addition, even a person who can only take a lateral posture is difficult to open the crotch from the posture. In these cases, a rectangular flat urine pad such as the urine pad described in Patent Document 1 is difficult to insert through a narrow crotch, and the urine pad is disposed so as to be in close contact with the wearer's skin. It was difficult. That is, it cannot be said that it can be exchanged quickly and easily, and still leaves room for improvement.

  The present invention has been made in view of such problems of the prior art, such as those who are paralyzed or joint contracture, or those who cannot sleep on their back and can only take a lateral position. It is an object of the present invention to provide a urine pad that can be easily worn and replaced quickly and easily even by a person who cannot open the crotch.

  As a result of intensive studies in order to solve the problems of the prior art as described above, the present inventor can easily insert a gap between narrow groins if the pads are joined in a folded state in advance. And I thought that simple exchange could be achieved. And it was conceived that the said subject was solved by joining at least one edge part of a front-end part and a rear-end part in the state folded in the width direction, and completed this invention. Specifically, the following urine pads are provided by the present invention.

[1] An absorber, a top sheet that is at least partially made of a liquid-permeable material and arranged to cover the surface of the absorber, and a liquid-impermeable material that covers the back surface of the absorber and the backsheet arranged to, a urinary pad having a folded at least once in the width direction, the back faces by to be folded is abutting and abutted back faces The urine pad is temporarily fixed so as to be peelable at at least one of the front end portion and the rear end portion and the central portion in the front-rear direction .

[ 2 ] The urine pad according to [1 ], wherein a width of the end part temporarily fixed so as to be peelable is narrower than a product width.

[ 3 ] The urine pad according to [1] or [2] , wherein the absorbent body has a recessed portion or a punched portion formed along a position that becomes a fold when folded.

[ 4 ] The urine pad according to any one of [1] to [ 3 ], wherein the absorber is composed of a plurality of absorbers divided along a position that becomes a fold when folded.

[ 5 ] The urine pad according to any one of [1] to [ 4 ], wherein a reinforcing material having higher rigidity than that of the absorbent body is disposed at the end portion temporarily fixed to be peelable .

[ 6 ] The urine pad according to any one of [1] to [ 5 ], wherein a handle is attached to the end portion temporarily fixed to be peelable .

  The urine pad of the present invention can be easily and quickly worn even for people who cannot open the crotch because of paralysis, joint contracture, etc., or because they can only take a lateral position. Exchange work can be performed easily.

  Hereinafter, the best mode for carrying out the urine pad of the present invention will be specifically described. However, the present invention broadly encompasses urine pads having the invention-specific matters, and is not limited to the following embodiments.

[1]: urine pad:
The urine pad is folded at least once in the width direction as in the urine pad 1A shown in FIG. 1A to FIG. 1D, and the front and back surfaces (in the illustrated example, the surfaces of the backsheet 20) are applied by folding. The contacted and abutted front surfaces or back surfaces are joined at at least one of the front end portion 2 and the rear end portion 6 (the front end portion 2 in this example) (joint portion 50). ).

  Like the urine pad 1A, by joining the pad in a folded state in advance, the urine pad 1A can be inserted into the wearer's crotch with the folded state. Therefore, the urine pad 1A can be easily inserted into the crotch of a person who cannot open the crotch widely because of paralysis, joint contracture, or the like, or because only the lateral position can be taken.・ Simple exchange is possible. In addition, after inserting the urine pad into the crotch, as shown in FIG. 1D, the part on the end (rear end 6) side that is not joined can be expanded into a flat shape. Therefore, the surface of the urine pad 1A (the surface on the top sheet 18 side) can be more closely attached to the wearer's skin than in the folded state, and leakage can be suppressed.

  On the other hand, in the case of a flat urine pad, since both side edges of the pad hit the wearer's inner thigh, it is difficult to insert the pad between the crotch unless the crotch is widened. In addition, the urine pad is usually marketed in a state of being folded (C-folded) so that both side edges in the width direction are folded inward and folded in three in the front-rear direction. Therefore, the urine pad has a fold in the folded state as described above, and it is flexible and has low rigidity even if it is folded into a shape (folded in the width direction) different from the fold when used. Therefore, it is difficult to fold properly. Moreover, even if it can be folded, it is difficult to maintain that state. Therefore, it is difficult to insert the pad into the wearer's crotch with the pad folded.

[1-1] Folding form:
The urine pad has a structure folded at least once in the width direction like the urine pad 1A shown in FIG. 1B. In general, urine pad, as the urine pad 1A shown in FIG. 1B, the absorbent body 22, to be constructed as a laminate of topsheet 18 and backsheet 20, the urine pad, the laminate is folded together It will be.

  The “width direction” means a direction orthogonal to the front-rear direction of the urine pad, that is, the left-right direction. The urine pad is often configured to have a shape that is long in the front-rear direction and short in the left-right direction, such as a substantially rectangular shape. Therefore, the short direction is usually the “width direction”. “Fold in the width direction” means that the urine pad is folded using a center line in the width direction or a straight line parallel thereto as a fold. The urine pad 1A illustrated in FIGS. 1A to 1C is an example in which the urine pad 1A is folded using the center line Lc in the width direction as a fold.

  The “width direction center line” is a straight line passing through the center of the urine pad 1A in the front-rear direction of the urine pad 1A as shown in FIG. 1C. In other words, it can also be referred to as a straight line connecting the midpoint of the front end E1 and the midpoint of the rear end E2 of the urine pad 1A.

  “At least once” means that the urine pad has a structure in which the urine pad is folded not only once but also a plurality of times is included in the scope of the present invention. However, if the number of times of folding increases, the thickness increases in the width direction, so that it becomes difficult to insert the gap into the gap between the crotch where the wearer has narrowed. Therefore, the number of times of folding is preferably 1 to 3, and preferably 1 time.

  The folding method for folding the urine pad is a mountain fold, in which the front side (top sheet 18 side) of the urine pad is convex and the back side (back sheet 20 side) is concave, like the urine pad 1A shown in FIG. 1B. Alternatively, the urine pad 100A shown in FIG. 2A may be a valley fold in which the front side (top sheet 18 side) of the urine pad is concave and the back side (back sheet 20 side) is convex. .

  When it is mountain-folded, the shape approximates the shape of the wearer's crotch. Therefore, the urine pad can be easily brought into close contact with the wearer's skin, and the substantial absorption area can be increased. Therefore, urine leaks along the wearer's skin, so-called transmission leakage can be prevented, and since urine can be received and absorbed at a position close to the urination part, leakage other than transmission leakage hardly occurs. There is an effect. If it is valley-folded, it can be said that the entire urine pad is easy to make concave and easy to receive urine. Therefore, compared to the case of mountain folding, there is an effect that urine leaks from the side edge along the surface of the urine pad. In addition, the male genitalia easily fits in the space formed by the valley fold, and there is an effect that the skin contact and the feeling of wearing are good, so that it can be suitably used particularly as a urine pad for men. When a plurality of urine pads are folded, mountain folds and valley folds may be mixed, as in the urine pad 100C shown in FIG. 2C.

  Specific forms of the folding structure include: a) a urine pad 1A shown in FIG. 1B, such as a reverse U-shaped section folded once in a mountain fold; b) a urine pad 100A shown in FIG. 2A, U-shaped section folded once in a valley fold, c) N-shaped section folded once in a mountain fold and a valley fold, such as the urine pad 100B shown in FIG. 2B, d) Urine shown in FIG. 2C A cross section M-shaped folded in total in the order of mountain fold, valley fold, and mountain fold, such as pad 100C, e) Valley fold, mountain fold, valley fold, in the order of urine pad 100D shown in FIG. 2D The shape of the cross-section W shape etc. which were folded 3 times in total can be mentioned.

  The fold when folding is preferably formed at a position where the width of the urine pad is divided substantially evenly. For example, the urine pad 1A shown in FIG. 1B and the urine pad 100A shown in FIG. 2A are folded in half so that the left and right regions are substantially even with the width direction center line Lc as a fold. Such a bi-fold shape is a symmetrical shape, which is preferable because it has the advantage of no left-right directionality. Moreover, the urine pad 100B shown in FIG. 2B is also a form folded in three so that the width of the urine pad is divided into approximately three equal parts by two folds. This form is an asymmetrical form, but when applied to the wearer in the lateral position, on the lower side of the wearer's body, on the upper side of the wearer's body, It is preferable to arrange and use a mountain fold portion that is unlikely to cause transmission leakage because it can effectively prevent leakage.

  Also preferred is a form in which the side edge is further folded narrowly after being folded in half so that the left and right regions are substantially equal with the center line in the width direction as the crease. For example, the urine pad 100C shown in FIG. 2C is a modification of the form of the urine pad 100A shown in FIG. 2A, and is folded in half (valley fold) so that the left and right regions are substantially equal with the center line Lc in the width direction as a fold. This is an example in which the side edge portion is further folded narrowly after being folded into two. A urine pad 100D shown in FIG. 2D is a modification of the urine pad 1A shown in FIG. 1B. The urine pad 100D is folded in half (mountain fold) so that the left and right regions are substantially equal with the center line Lc in the width direction as a fold. This is an example in which the side edge portion is further folded narrowly. These forms are preferable because they have both the advantage of valley fold and the advantage of mountain fold compared to the form shown in FIG. 1B or 2A.

  Among the forms described above, the form shown in FIG. 1A and FIG. 2A is preferable because the production is easy including the packaging process, and it is easy to insert into the narrow gap between the wearer's crotch. The form shown in FIG. 2A is particularly preferable in that it is formed in a concave shape that is easy to receive and is less likely to leak.

Urine pad of the present invention, the back faces by to be folded as described above are abutting. The “ back surface” means the back surface of the urine pad, and means the surface on the side in contact with the clothing (including disposable diapers) of the members constituting the urine pad as well as the surface of the back sheet. For example, when a part or all of the surface of the back sheet is covered with the cover sheet, the surface of the cover sheets or the form in which the surface of the cover sheet and the surface of the back sheet are in contact with each other is also referred to as “back surface”. They are in contact with each other, and are included in the scope of the present invention.

[1-2] Joining form:
Urine pad of the present invention is abutted back faces as described above has been temporarily fixed (joined) peelably at least one end of the front and rear ends. Even if only the center part of the urine pad is joined, a certain degree of effect can be obtained, but the urine pad should be attached to the wearer first if the front end part or the rear end part of the urine pad inserted between the crotch of the wearer is joined first. It is because it is easy to insert between groins.

  “At least one end portion of the front end portion and the rear end portion” means one end portion or both end portions of the front end portion and the rear end portion of the urine pad. That is, only the front end part or only the rear end part may be joined, or both the front end part and the rear end part may be joined. And as long as the front-end part or the rear-end part is joined, the other part (for example, center part) may be joined. However, the form which joined only one edge part can spread the part by the side of the edge part (rear end part 6) which is not joined, as shown to FIG. 1D. Therefore, the surface of the urine pad 1A (the surface on the top sheet 18 side) can be more closely attached to the wearer's skin, and leakage can be suppressed. Further, by expanding the flat shape, it is possible to secure a wide absorption area on the back side (butt side) where urine can easily go around in the supine position and the lateral position, so that leakage can be suppressed. In addition, in the case of a male, the absorption area around a male genital area can be secured widely with the flattened portion as the ventral side, and leakage can be effectively suppressed.

  In this specification, the longest portion in the front-rear direction of the urine pad is defined as the reference (full length), the portion from the front end of the urine pad to 20% length is the “front end”, and the length from the rear end of the urine pad is 20% long. The portion up to this point is the “rear end portion”, and the portion 60% long on the center side of the urine pad excluding the front end portion and the rear end portion is the “center portion”.

  There is no particular limitation on the bonding method. Examples thereof include adhesion using an adhesive such as a hot melt adhesive, mechanical engagement using a mechanical fastener, adhesion using an adhesive, and heat fusion using heat sealing. In addition, the bonding includes a detachable temporary fixing.

Urine pad of the present invention is abutted back surfaces each other, that have been temporarily fixed peelably at least one end of the front and rear ends. By temporarily joining the joint, the urine pad can be folded and joined into the wearer's crotch, and then the temporary fastening can be peeled off to spread the urine pad into a flat shape. Such a form allows the urine pad to be easily inserted into the crotch. Further, there is an advantage that leakage can be effectively prevented by increasing the contact area between the urine pad and the wearer's skin during use.

  For example, the form which joins the front-end part of a urine pad by a normal method, and joins the rear-end part with the temporary fixable which can be peeled is also preferable. In such a form, since both ends are joined when the urine pad is inserted into the wearer's crotch, the urine pad can be easily inserted into a narrow gap between the crotch. Moreover, since the temporary fixing part can be peeled off during use, the surface of the urine pad is spread with respect to the wearer's skin by spreading the rear end part into a flat shape in the same manner as the urine pad 1A shown in FIG. 1D. It is also possible to suppress the leakage.

  “Temporarily fixed so that it can be peeled off” means that a material such as a top sheet that is temporarily fixed when it is peeled torn to the extent that it can be easily peeled by human power, It means that it is fixed to the extent that it does not break.

  Specifically, it is preferable that the peeling force of 180 ° peel measured in accordance with JIS K6854 is fixed in the range of 0.3 to 5.0 N. When the peeling force is less than 0.3 N, the adhesive force is too weak, and even when a urine pad is worn, the peeling may occur unintentionally even when the peeling is not required. Moreover, when peeling force exceeds 5.0 N, adhesive force is too strong and a temporary fix part may be hard to peel. In order to acquire the said effect more reliably, it is more preferable that peeling force is the range of 0.5-3.0N.

  The method of temporary fixing is not particularly limited as long as it is temporarily fixed with the peeling force as described above. For example, a method such as adhesion by hot melt adhesive, hot embossing, ultrasonic welding, etc., extremely weak welding or pressure bonding Can be mentioned.

Urine pad of the present invention is abutted back surfaces each other, that have been temporarily fixed separably in the central portion of the front-rear direction. By central portion in the urine pad is temporarily fixed, it is possible to adjust the spread condition of the urine pad according to the position and area of peeling the temporary fixing. In this form, a) a strong part (non-temporary fastening part) is formed at the end part, and a temporary fastening part is formed at the central part, and b) temporary fastening parts are provided at both the end part and the central part. The formed form is included.

  For example, the urine pad 1B shown in FIGS. 3A to 3C has a form in which the temporary fixing portions 52 are disposed at both the end portions (the front end portion 2 and the rear end portion 6) and the central portion 4. Since the urine pad 1B is provided with the temporary fixing portions 52 over almost the entire contact surface between the back sheets 20, the urine pad 1B is folded when the urine pad 1B is inserted into the wearer's crotch. It is reliably maintained. In addition, when the urine pad 1B is used, all or part of the temporary fixing portion 52 can be peeled into a desired shape. Therefore, the urine pad 1B can be expanded in a shape that matches the wearer's body shape, and leakage is unlikely to occur.

  As in the urine pad 1C shown in FIGS. 4A to 4C, a form in which a plurality of temporary fixing portions 52 are intermittently formed on the contact surface is also preferable. In such a form, the spread of the urine pad 1C is adjusted stepwise by the number of peeling of the temporary fixing part 52, as compared with the form in which the temporary fixing part is formed over the entire contact surface. There is an advantage that can be.

  The example shown to FIG. 4A is an example in which the rectangular temporary fix | stop part 52 was formed intermittently. The temporary fixing portions 52 formed at three positions from the front end portion 2 to the central portion 4 have different lengths, and the temporary fixing portions 52 closer to the center line Lc in the width direction of the urine pad 1C are formed longer. In such a configuration, since the temporary fixing portion 52 on the urine pad side edge side is short, the rear end portion 6 side of the urine pad 1C can be widened without peeling off the temporary fixing portion 52. Then, by peeling off the temporary fixing portion 52 at one place or a plurality of places according to the wearer's body shape, the spread of the urine pad 1C can be finely adjusted in three stages.

  When the plurality of temporary fixing portions are intermittently formed, the shape of the temporary fixing portions is not limited to rectangular shapes having different lengths as shown in FIGS. 4A to 4C. For example, if small circular temporary fixing portions are arranged in a matrix (matrix shape), the temporary fixing portions can be peeled in steps in two directions, and the urine pad can be spread more easily and accurately. Can be fine-tuned.

  When a plurality of temporary fixing portions are intermittently formed, it is not necessary to make the peeling forces of all the temporary fixing portions equal, and different values may be used depending on the purpose. In the urine pad of the present invention, it is preferable that the peeling strength of the temporary fixing portion far from the fold is lower than the peeling strength of the temporary fixing portion near the fold when folded. For example, if this configuration is applied to the urine pad 1C shown in FIGS. 4A to 4C, the peel strength of the shortest temporary fixing portion 52 is the lowest and the peel strength of the longest temporary fixing portion 52 is the highest. What is necessary is just to comprise.

  Such a configuration makes it easy to peel off the temporary fastening part far from the fold by making the peeling strength easy, while making the peeling strength of the temporary fastening part 52 near the crease high to make it difficult to peel off. That is, it can be configured to be easy to peel off a portion that has a high possibility of peeling, and to make it difficult to peel off the other portions so as not to unintentionally peel off.

[1-3] Overall form of urine pad:
There is no particular limitation on the form of the entire urine pad except for the form of folding and joining. However, the shape before folding is preferably a vertically long shape such as a substantially rectangular shape or a substantially elliptical shape. With such a shape, there is an advantage that the entire excretory organ can be reliably covered and can be easily inserted into the wearer's crotch.

The urine pad is a urine pad 1D shown in FIGS. 5A and 5B, a urine pad 1E shown in FIGS. 6A and 6B, and an end portion temporarily fixed so as to be peelable (see FIG. 7A to FIG. 7C). In the illustrated example, it is preferable that the width W1 of the front end portion 2) is narrower than the product width W2. In addition to joining the urine pad in a folded state, it is easier to insert the urine pad between the wearer's crotch by configuring the width of the joined end portion to be narrow.

  As used herein, “width” means the width in a state before the urine pad is folded, as shown in FIG. 5B and the like. Usually, the product width W2 of the urine pad is about 180 to 450 mm, and the maximum width of the central portion 4 whose width is not adjusted corresponds to this. The width of the joined end portions is preferably 250 mm or less, and more preferably 200 mm or less, because it is easy to insert into the narrow crotch gap. On the other hand, the urine pad inserted into the crotch gap needs to be pulled to some extent from the inserted side and the opposite side for positioning, but at that time, it functions as a tab when pulling out the urine pad from the crotch gap In order to ensure a sufficient size, the thickness is preferably 50 mm or more, and more preferably 100 mm or more.

  Moreover, it is preferable that the urine pad of this invention has the recessed part or the punching part along the position used as a crease | fold when an absorber is folded. By forming a fragile portion such as a concave portion or a punched portion, the portion can be easily bent, so that the folded and joined state can be easily maintained.

  The urine pad 1E shown in FIGS. 7A to 7C is a urine pad folded along the center line Lc in the width direction, and a recess 54 (groove) is formed in the absorbent body 22 by embossing along the center line Lc in the width direction. This is an example of formation. Moreover, the urine pad 1F shown in FIGS. 8A to 8C is also a urine pad folded along the width direction center line Lc, and a part of the absorber 22 is punched out linearly along the width direction center line Lc. This is an example in which a punching portion 56 is formed.

  There are no particular restrictions on the positions at which the recesses or punched portions are formed as long as they are along the crease. However, like the urine pad 1F shown in FIG. 7A to FIG. 7C and the urine pad 1G shown in FIG. 8A to FIG. 8C, the concave portion 54 and the punched portion 56 are located in the vicinity of the joined end portion (the front end portion 2 in the illustrated example). Preferably it is formed. Since the urine pad of the present invention is intended to be inserted into the wearer's crotch from the joined end side, it is desirable that the part is folded and maintained in a joined state. is there.

  As for the urine pad of this invention, the absorber 22 is comprised from several absorber 22a, 22b divided | segmented along the fold of the urine pad 1I like the urine pad 1I shown to FIG. 9A-FIG. 9C. Is preferred. By dividing the absorber, the absorber does not exist in the part corresponding to the crease, and the folded and bonded state is maintained as compared with the case where the concave portion is formed or the punched portion is formed in part. It becomes easy to do. This form can be said to be an extreme example of a form in which a punched part is formed in a part corresponding to the fold of the absorber.

  The urine pad 1I shown in FIG. 9A to FIG. 9C has the width direction center line Lc as a fold, and the absorbent body is divided into two at this portion. It may be divided into two or more.

The urine pad of the present invention has rigidity compared to the absorbent body 22 at an end portion (front end portion 2 in the illustrated example) temporarily fixed so as to be peelable , like a urine pad 1J shown in FIGS. 10A to 10C. It is preferable that a high reinforcing material 58 is provided. The urine pad of the present invention is used by inserting it into the wearer's crotch from the end side temporarily fixed so as to be peelable . However, when the urine pad is designed to be thin, a soft absorbent body with no stiffness is used, so even if it is inserted in the crotch in a folded state, the urine pad may be folded in the middle, etc. It may be difficult to insert into. In such a case, if a reinforcing material having higher rigidity than the absorbent body (that is, having stiffness and having a certain degree of hardness) is disposed, the urine pad can be easily inserted into the crotch.

  Examples of the material of the reinforcing material include a plate-like body made of urethane foam, felt, a resin such as polyethylene resin, an airlaid nonwoven fabric, or the like. However, it is preferable that the material does not give a foreign object feeling when worn. For example, it is also a preferable form that an absorbent body having higher rigidity than the original absorbent body is disposed as a reinforcing material. This is because it is difficult to give a sense of foreign matter and also serves to assist the absorption performance of the original absorbent body.

  In addition, about the rigidity value of a reinforcing material, it is preferable that it is 100-700g by a measured value with a handle-ometer, and it is still more preferable that it is 150-600g. If the rigidity value is less than 100 g, the rigidity is insufficient, so that it may be difficult to insert when passing through a narrow gap in the crotch portion. On the other hand, since it will become hard if it is over 700 g, depending on a wearer's posture, it may hit a skin and may feel a pain and there exists a possibility that a feeling of wear may worsen. Here, the “rigidity value” in this specification is a value measured by a handle-ometer. The measurement is performed according to JIS L1096, and is a value obtained by measuring a force required when a sample having a length of 150 mm and a width of 50 mm is pressed with a blade.

In the urine pad of the present invention, a handle 60 is attached to an end portion (front end portion 2 in the illustrated example) that is temporarily fixed so as to be peelable , like a urine pad 1K shown in FIGS. 11A and 11B. preferable. By attaching a handle, after inserting a part of the urine pad into the crotch from the wearer's back side, it is possible to pull the handle from the wearer's abdomen side. It is possible to insert a pad. Further, even after using the urine pad, the urine pad can be easily pulled out from the narrow crotch by pulling the handle.

  As a material for the handle, a non-woven sheet or the like that is soft against the skin and excellent in touch can be suitably used. The shape of the handle is not particularly limited, but it is preferable that a hole 62 into which a finger can be inserted when the handle 60 is pulled is formed as in the handle 60 shown in FIGS. 11A and 11B.

[2] Other components of the urine pad:
The urine pad, like the urine pad 1A shown in FIGS. 1A to 1C, is composed of the absorbent body 22 and at least a part of a liquid-permeable material, and the top sheet 18 arranged so as to cover the surface of the absorbent body 22. And a back sheet 20 made of a liquid-impermeable material and disposed so as to cover the back surface of the absorber 22.

[2-1] Absorber:
The “absorber” is a member for absorbing and holding the wearer's urine and the like, and is made of an absorbent material. Usually, the absorber is sandwiched between a top sheet and a back sheet, and used in a state of being integrated with both sheets.

  Examples of the “absorbent material” include fluff pulp, super absorbent polymer (hereinafter referred to as “SAP”), a hydrophilic sheet, and the like. “Fluff pulp” is made by pulverizing wood pulp or non-wood pulp into cotton, “SAP” is sodium polyacrylate, “Hydrophilic sheet” is tissue, absorbent paper, hydrophilized It is preferable to use a non-woven fabric that has been treated.

  As the absorber, it is preferable to use one or two or more absorbent materials formed into a single-layer or multi-layer mat. Especially, what combined 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be mixed in the fluff pulp mat or used in a layered manner between the fluff pulp mats.

[2-2] Top sheet:
Since the top sheet needs to allow the wearer's urine or the like to pass therethrough, at least a part (all or a part) of the top sheet is made of a liquid-permeable material.

  Examples of the “liquid permeable material” include woven fabric, non-woven fabric, and porous film. Among these, it is preferable to use a nonwoven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, aliphatic polyamide, etc., which has been subjected to a hydrophilic treatment.

  As the “nonwoven fabric”, a nonwoven fabric produced by a production method such as air through (card hot air) or card embossing can be suitably used. The “hydrophilic treatment” can be performed by applying, spraying, impregnating, etc. a surfactant.

  The top sheet is preferably “at least partly”, more specifically, when the top sheet is viewed in plan, at least the vicinity of the surface of the absorber is made of a liquid-permeable material.

[2-3] Backsheet:
The back sheet is a sheet disposed so as to cover the back surface of the absorbent body (the surface located on the side far from the wearer's skin when the urine pad is attached). The back sheet is made of a liquid-impermeable material because it is necessary to prevent the wearer's urine from leaking outside the urine pad.

  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. 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.

[2-4] Solid gathering:
The urine pad of the present invention preferably includes at least a pair of three-dimensional gathers 26 that are made of a water-repellent sheet 32 and are disposed on both sides of the absorbent body 22 as in the urine pad 1G shown in FIGS. 8A to 8C. .

  The structure used for the conventional disposable diaper and a urine pad can be employ | adopted for the structure of a three-dimensional gather. For example, as in the urine pad 1G shown in FIG. 8B, an elastic material (three-dimensional gather elastic material 36) is sandwiched and fixed between the layers of the water-repellent sheet 32, and the gathers (襞) are caused by the contraction force of the three-dimensional gather elastic material 36. What was formed can be used suitably. The water-repellent sheet may be a nonwoven fabric produced by a production method such as card embossing or spunbonding, but a nonwoven fabric sheet such as SMS or SMMS having a high waterproof property is more preferable.

  The three-dimensional gather may be separately provided with a water-repellent sheet 32 for the three-dimensional gather 26 as in the urine pad 1G shown in FIG. 8B, or a sheet material (for example, the back sheet 20) constituting the urine pad. You may form by a part.

[2-5] Elastic material:
In the urine pad of the present invention, the elastic material 40 may be disposed on both side edges or the like as in the urine pad 1A shown in FIGS. 1A to 1C. By disposing this stretchable material, it is possible to form a gather that is rich in stretchability at both side edges of the urine pad. Therefore, it becomes difficult to form a gap at both side edges of the urine pad, and so-called side leakage can be effectively prevented.

  When the three-dimensional gather 26 is attached like the urine pad 1G shown in FIGS. 8A to 8C, it is preferable that the stretchable material is disposed on the outer side of the standing line of the three-dimensional gather 26. 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.

  Regarding the stretchable material, the constituent material, the elongation rate of the material, the stretched state at the time of fixing, and the like may be determined in consideration of the degree of gather contraction and the like.

  As an elastic material, the elastic material used with the conventional disposable diaper and the urine pad can be used suitably. 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 components of the urine pad 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.

  The urine pad of the present invention will be described more specifically with reference to the drawings. However, the urine pad of the present invention includes all urine pads having the invention-specific matters, and is not limited to the following examples.

[ Reference Example 1]
As a urine pad of Reference Example 1, a urine pad 1A shown in FIGS. 1A to 1C was produced. This urine pad 1A is a urine pad for adults, and has a length of 490 mm and a width of 210 mm. The absorber used was a flat type (thickness that was not formed into a bent shape) having a thickness of 4 mm and a rigidity value of 200 g.

  As shown in FIGS. 1A to 1C, the urine pad 1 </ b> A has a center line Lc in the width direction as a crease, and the front side (top sheet 18 side) of the urine pad 1 </ b> A is convex and the back side (back sheet 20 side) is concave. It was constructed in an inverted U-shaped cross section that was folded once into a mountain fold.

  The surfaces of the back sheets 20 were brought into contact with each other by the above-described folding, and the surfaces of the back sheets 20 were joined at the front end portion 2 of the urine pad 1A. 1C, the hot melt adhesive is applied to the portion corresponding to the lower joint 50 in FIG. 1C, the urine pad 1A is folded along the center line Lc in the width direction, and pressed in that state. Formed. Thereby, the surfaces of the back sheets 20 were joined at the front end 2 of the urine pad 1A.
