Description

  The present invention relates to an auxiliary sheet for a nursing diaper that is used by being attached to the inside of a nursing diaper that covers at least the buttocks of a user.

  Conventionally, disposable care diapers used for the care of users (caregivers) are widely known. However, such care diapers have a large amount of user's excrement attached to the user's own body. Therefore, the caregiver needs to wipe off excrement adhered to the body when changing the diaper. In this way, caregivers are forced to perform work that they want to avoid as much as possible, and the caregiver's labor and time associated with this work are further wasted, as well as the physical and mental health of the user accompanying excrement deposits. Discomfort cannot be ignored. In addition, when wiping the excrement adhered to the user's body, paper and towels are required, so there is a problem that causes wasteful consumption of water or the like for rinsing the paper or towel used at this time, In particular, since such operations are repeated every day, frequent consumption of paper, water, and the like has a problem in that it is disadvantageous from the viewpoint of saving resources and economically.

  On the other hand, various auxiliary sheets for diapers for solving this problem (auxiliary tool, inner sheet part) have also been proposed, and in Patent Document 1, the diaper main body that covers at least the buttocks of the user is overlapped. A diaper aid to be used, which is a belt-like part that is fixed to the inside of the diaper body or to the user's waist, and extends from the belt-like part, covers the buttocks when worn on the user, It is possible to fix to the belt-like part located in the user's abdomen by extending from this cover part and passing through the user's crotch. A diaper assisting tool in which at least one band part is integrally formed of a sheet member is disclosed, and Patent Document 2 covers the buttocks when worn on the user, and the user's anal part In the position corresponding to It is a cover part provided with an aperture part through which the excrement formed can pass, and this cover part is made of a paper material that does not lose its shape or does not easily lose its shape, and has a shape of at least a part of the bottom part. An auxiliary tool for diapers formed as a molded body formed by a mold along the line is disclosed, and Patent Document 3 further includes a left seat portion and a right seat portion, and a gap between the left seat portion and the right seat portion. A slit in the front-rear direction with zero is provided, and each inner end side part located on both sides of the slit part is formed as an elastic stretch part that can be stretched in the front-rear direction by including a rubber material. The other parts are formed as gather parts, and at least the front edge part and the rear edge part of the left sheet part and right sheet part can be retrofitted or fixed to the inner surface of the diaper body part, respectively. Inner sheet portion is disclosed in which the whole was made by forming a paper stock.

  However, the above-described conventional auxiliary sheet (diaper auxiliary tool, inner sheet part) still has the following problems to be solved.

  First, even diapers fitted with conventional aids are used for sleeping users, so avoid attachment to the body depending on the wearing state of diapers and the quality and quantity of excreta. This is not easy, and in actuality, there is a considerable amount of adhesion. Therefore, how to reduce the amount of adhesion to the body is an important technical issue, but conventional diapers and their aids are not necessarily related to the approach (improvement) from the viewpoint of how to reduce the amount of adhesion. It was not enough and there was room for further improvement.

  Secondly, since these types of diapers and aids are used every day, it is also important to reduce manufacturing costs from the viewpoint of reducing the economic burden on the user, and the structure and manufacturing process are as simple as possible. It is desirable to make it. On the other hand, since a user uses for a long time in a sleeping state, the user's comfort when wearing a diaper or an auxiliary tool is an important issue that cannot be ignored. However, in the case of this type of auxiliary tool (auxiliary seat), wearing comfort is sacrificed in order to reduce the cost, while on the other hand, in order to increase wearing comfort, the cost is increased and the wearing comfort and cost are reduced. It was not easy to make both of them compatible.

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, the structure and manufacturing method of the nursing diaper auxiliary sheet 1 according to the present embodiment will be described with reference to FIGS.

  FIG. 1 shows the entire configuration of the assisting diaper auxiliary sheet 1 and also shows a surface that contacts the skin of the user H, that is, a non-contact surface 2n that is the back surface of the skin contact surface 2s. Accordingly, the non-contact surface 2n shown in FIG. 1 is a surface to be attached to the inner surface 20i of the care diaper 20 described later. The auxiliary sheet 1 has, as a basic configuration, a sheet body portion 2 that is rectangular in its entirety, and a front adhesive portion 5f that is provided in the vicinity of the front end side 2nf of the non-contact surface 2n of the sheet body portion 2. A rear adhesive portion 5r provided in the vicinity of the rear end 2nr of the contact surface 2n.

  The sheet body 2 includes a plurality of sewing portions J1, J2, J3, in which the rubber thread 3 is sewn along the front-rear direction Fs with respect to a plurality of positions in the left-right direction Fw of the sheet material Sc using the nonwoven fabric C. ... By providing J9 and J10, the whole is manufactured in a gather shape so that the sheet material Sc can expand and contract in the front-rear direction Fs. The type of the nonwoven fabric C used for the sheet material Sc is not particularly limited to a specific material, but a nonwoven fabric excellent in low cost and good in touch is desirable. As an example, a thermal bond nonwoven fabric (trade name) manufactured by Rengo Non-Woven Products Co., Ltd. can be used. This non-woven fabric is obtained by processing a short plastic fiber as a raw cotton into a non-woven fabric by no-binder and heat-sealing, and is excellent in hygiene and flexibility.

  Further, as shown in FIG. 2, the sheet main body 2 in the present embodiment uses two sheet materials Sc and Sc in an overlapping manner. In this case, the number of sheet materials Sc to be used is arbitrary. As illustrated, the use of two sheet materials Sc is the most desirable embodiment from the viewpoint of achieving both wearing comfort and cost reduction, but in addition, a single sheet may be used. If necessary, three or more sheets may be used. As described above, since the number of sheet materials Sc to be used can be arbitrarily selected, the degree of wearing comfort and the degree of cost reduction can be easily adjusted, and thus there is an advantage that diversification of product grades can be easily realized. .

  On the other hand, a rubber thread 3 disposed on the non-contact surface 2n of the sheet main body 2 and a natural fiber thread 11 such as a cotton thread for sewing the rubber thread 3 to the sheet main body 2 are used for the sewing portion J1. Therefore, when sewing is performed, one of the rubber thread 3 or the natural fiber thread 11 is set as an upper thread and the other is set as a lower thread in a sewing machine such as a sewing machine. Then, sewing is performed along the front-rear direction Fs with respect to a preset position in the left-right direction Fw of the two overlapped sheet materials Sc, Sc. At this time, the two sheet materials Sc and Sc are loosened in the front-rear direction. Thereby, as shown in FIG.1 and FIG.2, the rubber thread 3 is distribute | arranged to the non-contact surface 2n in the sheet | seat main-body part 2 (sheet material Sc ...), and the natural fiber yarn 11 is exposed to the skin contact surface 2s. . In the case of the example, as shown in FIG. 3, ten sewn portions J1... J10 are provided at preset positions, so that the other sewn portions J2. Can be provided. In this way, the rubber yarns 3 arranged on the non-contact surface 2n of the sheet main body 2 and the natural fiber yarn 11 for sewing the rubber yarns 3 on the sheet main body 2 to the sewing portions J1, J2, J3. ... is advantageous in that it is possible to avoid the problem that the rubber thread 3 directly hits the skin of the user H while ensuring the necessary stretchability.

  The positions of the respective sewing portions J1... J10 on the sheet material Sc... Are set in advance, and the respective sewing portions J1. In the case of illustration, as shown in FIGS. 1 and 3, the slits 4 along the front-rear direction Fs are formed at the center position in the left-right direction Fw of the seat body 2 after providing the respective sewing portions J1. For this reason, a sewing portion JM formed by a pair of left and right inner sewing portions J1 and J2 is provided at a central position in the left-right direction Fw of the seat body portion 2. Thereby, one inner sewing part J1 is arranged at a position near the left side of the slit 4, and the other inner sewing part J2 is arranged at a position near the right side of the slit 4.

  Further, an outer sewing part JP having a relatively large elasticity relative to the sewing parts J7 at other positions is provided in the vicinity of the left end side 2p of the sheet main body part 2 (sheet material Sc ...), and In the vicinity of the right end side 2q of the seat main body 2, an outer sewn portion JQ having a larger elastic force than the sewn portions J9 at other positions is provided. In this case, the outer sewing portion JP is constituted by a plurality (two for example) of sewing portions J3 and J4, and the elastic force is set to be large by narrowing the interval Lp between the sewing portions J3 and J4. At the same time, the other outer sewn portion JQ is similarly configured by a plurality (two examples) of sewn portions J5 and J6, and the interval (Lp) between the sewn portions J5 and J6 is reduced. Set the force large. With this setting, even if the sewing parts J1... Are provided in a common format, the pressure contact force (adhesion) to the skin of the user H can be selected by selecting the position and interval of each sewing part (J3...). Force) can be set, so that there is an advantage that leakage of excrement E from the outer sewing portion JP. Accordingly, in the illustrated example, the sewn portions J7 and J8 are provided between the outer sewn portion JP and the inner sewn portion J1, but the interval between the outer sewn portion JP and the sewn portion J7, the sewn portions J7 and J8, The interval and the interval between the sewn portions J8 and J1 are both wider than the interval Lp between the sewn portions J3 and J4 constituting the outer sewn portion JP. Similarly, sewing portions J9 and J10 are provided between the outer sewing portion JQ and the inner sewing portion J2, but the interval between the outer sewing portion JQ and the sewing portion J10, the interval between the sewing portions J10 and J9, The interval between the sewn portions J9 and J2 is larger than the interval (Lp) between the sewn portions J5 and J6 constituting the outer sewn portion JQ.

  If the sewing parts J1... J10 are provided, the sheet materials Sc and Sc are pressed between the pair of flat plates, for example, in a direction perpendicular to the plane. As a result, the loose portions of the sheet materials Sc, Sc are crushed, and as shown in FIG. 2, a large number of portions are partially crushed, and the whole is formed in a gather shape. That is, the sheet material Sc (sheet body portion 2) can be elastically expanded and contracted in the front-rear direction Fs by the rubber yarns 3 and the sheet material Sc can follow expansion and contraction. At this time, it is desirable that the length at the time of extension is set so that the length before extension (before pulling) can be extended about 1.5 times.

  When the above steps are completed, as shown in FIGS. 1 and 3, the slit 4 along the front-rear direction Fs is formed at the center position in the left-right direction Fw of the sheet main body 2. In forming the slit 4, it is sufficient to simply cut and form it using a predetermined cutter or the like. The slit 4 selects the length Ls through which the excrement E can pass, and the front-rear direction center position of the slit 4 selects the position Xs in the front direction Ff relative to the front-rear direction center position of the seat body 2. . If selected in this way, the slit 4 having the first function that allows the passage of the excrement E and the second function that prevents the backtracking can be realized, and in particular, the pair of left and right inner sewing portions J1, J2 and By combining these, there is an advantage that optimization when realizing both the first function and the second function can be easily performed. Specifically, since the slit 4 is formed in the sewing portion JM, the inner sewing portion J1 is located near the left side of the slit 4, and the inner sewing portion J2 is located near the right side of the slit 4, In a state where the seat body 2 is extended in the front-rear direction Fs, the slit 4 is closed without a gap due to the extension of the inner sewing portions J1 and J2 provided on both sides of the slit 4. Thus, the sheet main body 2 can be obtained.

  An example of suitable dimensions in the sheet body 2 is shown in FIG. About 20 [cm] can be selected as the width dimension Lw in the left-right direction Fw. Further, the length dimension Lm in the front-rear direction Fs is changed depending on the size without changing the width dimension Lw. That is, in the case of the M size, the size is selected to be approximately 35 [cm], and the S size and the L size are changed based on the M size. Further, the length Ls of the slit 4 is selected to be about 7 to 8 [cm], and the distance Lf between the front end 2nf and the slit 4 in the sheet body 2 is selected to be about 2 to 3 [cm].

  On the other hand, the sheet main body 2 is provided with a front bonding portion 5f and a rear bonding portion 5r. Specifically, it is a non-contact surface 2n that is the back surface of the skin contact surface 2s that contacts the user's skin in the seat body 2 (the surface on which the rubber thread 3 does not exist), and the front end of the non-contact surface 2n A front adhesive portion 5f having a predetermined width Lc along the front end side 2nf is provided in the vicinity of the side 2nf, and a predetermined width Lc along the rear end side 2nr is provided in the vicinity of the rear end side 2nr on the non-contact surface 2n. A rear bonding portion 5r is provided. For the front adhesive part 5f and the rear adhesive part 5r, for example, a double-sided adhesive tape having a predetermined width Lc of about 10 to 20 [mm] can be used. Therefore, until use, a release paper is stuck on each of the front adhesive portion 5f and the rear adhesive portion 5r.

  Next, the usage method and function (action) of the assisting diaper auxiliary sheet 1 according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 4, the auxiliary sheet 1 according to the present embodiment is used in combination with a commercially available general care diaper 20 (for adults). Therefore, the nursing diaper 20 shown as an example includes a wide front body part 20f that covers the front side (abdominal side) of the body of the user (caregiver), and a crotch part 20d that has a narrow width that covers the crotch of the body. The entire back body part 20r that covers the back side (back side) of the body is configured as a whole, and an absorber that does not appear in the figure is provided inside the crotch part 20d. Further, the left and right sides of the crotch portion 20d have gather portions 22p and 22q including elastic stretch portions, and the front end edge of the front body portion 20f has an elastic stretch portion 22f and the rear end edge of the back body portion 20r. Has an elastic stretch part 22r. Furthermore, fastening tapes 21 using adhesive tapes or the like disposed at a total of four locations for fixing the both ends of the back body part 20r to the both ends of the front body part 20f are provided on the left and right ends of the back body part 20r. Have. In this case, the fastening tapes 21 are covered with release paper.

  And when using the auxiliary | assistant sheet | seat 1, first, as shown in FIG. 4, the one nursing diaper 20 and the one auxiliary | assistant sheet | seat 1 are prepared. And the inner surface 20i of the care diaper 20 is spread upward, and the auxiliary sheet 1 is fixed to a predetermined position Xj (FIG. 4) on the inner surface 20i. In this case, since the auxiliary sheet 1 has the release paper attached to the front adhesive portion 5f and the rear adhesive portion 5r, the front adhesive portion 5f and the rear adhesive portion 5r are removed from the nursing adhesive diaper 20 after each release paper is removed. Affixed to the inner surface 20i of the substrate. The pasting position (predetermined position Xj) is a center position in the left-right direction Fw on the inner surface 20i, and is preferably a position slightly rearward of the center position in the front-rear direction Fs. In addition, since the predetermined position Xj to be attached varies depending on the body shape, height, etc. of the user H, when the care diaper 20 is attached to the user H in advance, the position of the slit 4 is the anal part of the user H. It is desirable to determine the sticking position so that it is located directly under the head.

  In particular, the front adhesive portion 5f and the rear adhesive portion 5r have a sheet fixing function for fixing the auxiliary sheet 1 and, after being fixed, also have a function of preventing excrement leakage to the front and rear, respectively. Care is taken that the entire surfaces of the portion 5f and the rear bonding portion 5r are in close contact (adhesion) with the inner surface 20i of the care diaper 20. As a result, the space A (see FIG. 7) between the auxiliary sheet 1 and the inner surface 20i of the nursing diaper 20 is blocked by the front adhesive portion 5f and the rear adhesive portion 5r in the front-rear direction, and the outer sewing portions JP and JQ in the left-right direction. It is interrupted by.

  By the above, since attachment of auxiliary sheet 1 to care diaper 20 is completed, it can be used similarly to a normal care diaper thereafter. That is, the nursing diaper 20 (hereinafter referred to as a nursing diaper unit 30) with the auxiliary sheet 1 attached is laid under the buttocks Hh of a user (caregiver) H who is sleeping on a futon or bed, The front body part 20f is brought to the front abdomen through the inseam of the user H. And what is necessary is just to detach | leave from each fastening tape 21 ... provided in the back body part 20r located in the back side, and to affix and couple | bond with the front body part 20f mounted on the abdomen. In FIG.6 and FIG.7, the state which mounted | wore the user diaper unit 30 to the user H is shown with a schematic diagram. In the mounted state, the sewing portions J1 to J10 of the auxiliary sheet 1 are in an extended state, and the inner surface of the relatively thin auxiliary sheet 1 is pressed against the skin surface of the user H. The cross section in this state is shown in FIG.

  On the other hand, it is assumed that the user H wearing the care diaper unit 30 defecates. In this case, the excrement E from the user H passes through the slit 4 of the auxiliary sheet 1 due to its weight, and enters the space A between the auxiliary sheet 1 and the inner surface 20i of the care diaper 20 as shown in FIG. Be contained. At this time, even if the excrement E moves because the excrement E is soft or the user H moves, the movement in the front-rear direction is blocked by the front adhesive portion 5f and the rear adhesive portion 5r. . Further, the movement in the left-right direction is prevented by the outer sewing portions JP, JQ having a relatively large elasticity in the auxiliary seat 1. Furthermore, since the slit 4 is in a closed state due to the extension of the inner sewing portions J1 and J2 disposed in the vicinity of the left and right sides of the slit 4 in the auxiliary sheet 1, the return of the excrement E is prevented. Thus, the excrement E accommodated in the space A is held in the auxiliary sheet 1 in a stable state.

  Therefore, according to the auxiliary sheet 1 for a nursing diaper according to this embodiment, as a configuration of the main part, in the vicinity of the front end side 2nf in the non-contact surface 2n that is the back surface of the skin contact surface 2s of the sheet main body 2. The front adhesion portion 5f having a predetermined width Lc provided along the front end side 2nf and the back adhesion of the predetermined width Lc provided along the rear end side 2nr in the vicinity of the rear end side 2nr on the non-contact surface 2n. A plurality of sewn portions J1, J2, J3... At least a pair of left and right inner sewn portions J1, J2 respectively disposed in the vicinity of the left and right sides of the slit 4 and the left and right ends of the seat body 2 Since it includes a pair of left and right outer sewing parts JP, JQ which are provided in the vicinity of the sides 2p, 2q, respectively, and have a large elasticity relative to the sewing parts J7 at other positions. When using a general nursing diaper 20 , While using the care diaper 20, can be eliminated or greatly reduced the problem of excrement E is attached to the user's H own body.

  Further, the auxiliary sheet 1 has a plurality of sewing portions J1, J2, and a plurality of sewing portions J1, J2, which are formed by sewing the rubber thread 3 along the front-rear direction Fs with respect to a plurality of positions in the left-right direction Fw of the sheet material Sc using the nonwoven fabric C. By providing J3..., The sheet material Sc is formed in a gather shape and the whole in a rectangular shape so that the sheet material Sc can expand and contract in the front-rear direction Fs, and the slit 4 is formed in the front-rear direction Fs at the center position Xc in the left-right direction Fw. Since the seat body 2 is configured as a main part, the structure can be simplified and the manufacturing process can be simplified. Both wearing comfort and cost reduction can be achieved.

  Although the preferred embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the detailed configuration, shape, material, quantity, technique, and the like do not depart from the gist of the present invention. It can be changed, added, or deleted arbitrarily.

  For example, one or a plurality of sheet materials Sc can be used, but a mode in which a sheet member formed of another material (general paper) is combined with one (or a plurality of) sheet materials Sc ... is excluded. is not. Further, the natural fiber threads 11 are desirable as the threads for sewing the rubber threads 3 to the sheet main body 2, but the use of chemical fiber threads is not excluded. On the other hand, the outer sewn portion JP... Shows a case where the elastic force is set larger by narrowing the interval Lp... Between the plurality of sewn portions J3, J4. The elastic force may be set larger by using a relatively thick rubber thread 3. Furthermore, although the case where the elastic force of the outer sewing parts JP and JQ was set large was shown, the elastic force of the inner sewing parts J1 and J2 may be set as large as necessary. On the other hand, the slit 4 selects the length Ls through which the excrement E can pass, and the front-rear direction center position of the slit 4 selects the position Xs in the front direction Ff relative to the front-rear direction center position of the seat body 2. Although cases have been shown, other forms are not excluded.
