It means the longitudinal direction of the replacement sheet 1. The “width direction” means a direction orthogonal to the vertical direction (the horizontal direction when the diaper changing sheet 1 is unfolded).

(Structure of diaper changing sheet 1)
The diaper changing sheet 1 according to the present invention includes a sheet material 2 having a predetermined planar shape, and a plurality of joining means 3 provided on the surface side of the sheet material 2 and detachable from the outer surface of the tape-type paper diaper 10; 3, and the base end side of the sheet material 2 is fixed to the sheet material 2 in a non-peelable manner at the center in the width direction of the upper edge in the vertical direction of the sheet material 2, and the joint is detachable from the back surface of the sheet material 2. A tag tape 4 provided with a surface and a back surface side of the sheet material 2 are provided at a central portion and / or at an arrangement position corresponding portion of the paper diaper 10 to prevent a deviation between the installation surface and the sheet material 2. It is mainly composed of misalignment prevention means 5 and 6 for illustration.

  As shown in FIG. 1, the sheet material 2 has a flat shape that is long in the vertical direction, and has a size that can sufficiently cover at least the child's abdomen to the upper part of the leg with the child laid down. As shown in FIGS. 1 and 2, the sheet material 2 is on both sides of the sheet material 2 in the width direction and on the upper side of the sheet material 2 from an arbitrary point on the sheet side edge on the upper edge of the sheet. It is preferable to form inclined sides 7 and 7 in an oblique direction that becomes an outer shape line toward an arbitrary point. By forming the inclined sides 7 and 7, when the both sides of the diaper changing sheet 1 are developed, the upper side of the sheet material 2 is not bent and can be smoothly developed. The inclined sides 7 and 7 are linear in the illustrated example, but may be formed in a curved shape. Further, the sheet material 2 may be rectangular without forming the inclined side 7.

As a material which comprises the said sheet | seat material 2, it can be set as the simple substance or composite material of the material used for a normal diaper change sheet and packaging materials, such as polyethylene, a polypropylene, polyester, nylon, a nonwoven fabric, and cotton. When the sheet material 2 is a composite material, different materials can be used for the front side and the back side. For example, the front side can be a non-woven fabric with good touch and the back side can be nylon with leak-proof property. When polyethylene, polypropylene, polyester, or nylon is used as the material, the basis weight is 27 g / m ² or more, preferably 45 to 80 g / m ² , and the thickness is 23 μm or more, preferably 45 to 80 μm. If it is too thin, it tends to sway when placed under the child, and if it is too thick, it will be difficult to fold. On the other hand, when using a nonwoven fabric or cotton, for the same reason, the basis weight is preferably 17 to 60 g / m ² , preferably 20 to 30 g / m ² .

The sheet material 2 is provided with folding lines L1 to L4 along the vertical direction and the width direction, and is appropriately folded at the folding line position when the diaper changing sheet 1 is individually packaged. Specifically, as shown in FIG. 1, the folding line L1, L2 along the upper and lower directions on both sides against the heart during the width direction of the sheet material 2 is provided, vertical lower edge of the sheet material 2 Fold lines L3 and L4 are provided along the width direction at substantially equal intervals with a length obtained by folding the paper diaper into two in the front-rear direction.

  The positions of the folding lines L1 to L4 will be described in detail based on FIG. The positions of the folding lines L1 to L4 are set based on the dimensions of the folded paper diaper 10. The length A from the both edges in the width direction of the sheet material 2 to the fold lines L1, L2 is 1.3 times or less the diaper width direction length (absorber width) of the absorbent body constituting the paper diaper 10, and the fold line L1. , The length between L2 is less than or equal to B. If it is longer than this, when the sheet material 2 is folded in a tri-fold state so that both sides in the width direction of the sheet material 2 are overlapped with the central part during individual packaging, there is a possibility that both sides of the sheet material will be twisted. A preferred length A is 35 to 60% of the absorber width. The length B between the folding lines L1 and L2 is about 1.1 to 1.3 times the absorber width. This is a length with some margin when the sheet material 2 is folded in three in the width direction in addition to the absorber width. The length C from the upper end in the up-down direction of the sheet material 2 to the fold line L4 is about 0.1 to 0.5 times, preferably about 0.2 to 0.4 times the product front-rear direction length of the paper diaper. Since this C part (upper part of the sheet material 2) is a part that is joined to the back surface of the sheet material 2 as an unsealed end during individual packaging, the above dimensions are set to ensure the function as the unsealed end. Is. The distances D and E between the folding lines L3 and L4 formed at substantially equal intervals from the lower end in the vertical direction of the sheet material 2 are about 0.5 to 0.7 times the length of the absorbent body in the front-rear direction, In other words, the paper diaper folded in half in the front-rear direction of the diaper is dimensioned so that it can be fully packaged.

  On the other hand, the vertical length F of the sheet material 2 is about 1.1 to 1.5 times, preferably about 1.2 to 1.3 times the longitudinal length of the paper diaper. On the other hand, it is preferable that an arbitrary point on the sheet side edge, which is the intersection of the inclined side 7 and the sheet side edge, exists between the fold lines L3 and L4, and the length M from this point to the sheet lower end is the sheet M It is 80% or less, preferably 60 to 70% of the vertical length F of the material 2. In addition, it is preferable that arbitrary points on the sheet upper edge, which is an intersection of the inclined side 7 and the sheet upper edge, are provided outside the folding lines L1 and L2, respectively, and the length from this point to the folding lines L1 and L2 The length N is 5 to 20%, preferably 10 to 15%, of the length B between the folding lines L1 and L2. Here, the arbitrary point on the upper end is that the both sides in the width direction of the sheet material 2 are folded in a three-fold state so as to overlap the center part, and the both sides in the width direction are displaced and the adhesive layer of the tag tape 4 It is preferable to provide it within a range that does not overlap with the tag tape 4 so as not to be joined to the tape tape 4.

  The fold lines L1 to L4 are preferably provided with folds so as to be easily folded in the folding direction. This facilitates folding when the diaper changing sheet is individually mounted.

  The joining means 3 provided on the surface side of the sheet material 2 is preferably a mechanical joining type fastening tape. The mechanical joining type fastening tape has a large number of engaging pieces on its outer surface. Examples of the shape of the engagement piece include a letter shape, a J shape, a mushroom shape, and a T shape, but any shape may be used. Preferred is a T-shape.

  In the illustrated example, the joining means 3 is provided at three places in the width direction both sides and the width direction center on the lower side in the vertical direction of the sheet material 2. The joining means 3 on both sides in the width direction are provided in regions outside the fold lines L1 and L2 and below the fold line L3, respectively. Further, the joining means 3 at the center in the width direction is provided in a region at the center in the width direction of the sheet material 2 and below the fold line L3. The joining means 3 may be provided only on both sides in the width direction, or may be provided at four or more locations along the width direction on the diaper back side.

  The size of the joining means 3 is such that the sheet width direction length is 10 to 30 mm and the sheet vertical direction length is 20 to 50 mm for both side joining means 3 and 3, and the center part joining means 3 is The sheet width direction length is preferably 20 to 70 mm, and the sheet vertical direction length is preferably 25 to 50 mm.

  A tag tape 4 is provided on the outer surface side of the sheet material 2 and substantially at the center of the upper edge in the vertical direction. As shown in FIG. 3, the tag tape 4 is a member made of paper, plastic film, or the like. As shown in FIG. 3, the base end portion 4a is bonded to the sheet material 2 so as not to be peeled off, and a peelable adhesive layer 4b is formed on the protruding portion. A non-adhesive knob portion 4c is formed at the tip portion. The width b of the tag tape 4 is 8 to 25 mm, preferably 13 to 20 mm. If it is smaller than 8 mm, it is too narrow and difficult to pick, and if it is larger than 25 mm, the bonding force of the adhesive layer 4 b is excessively applied and the material cost increases. The total length c of the tag tape 4 is 20 to 60 mm, preferably 25 to 45 mm. If the length is shorter than 20 mm, the adhesive strength for individual packaging is insufficient, and if the length is longer than 60 mm, the peeling force is excessively applied and the material cost increases. The knob 4c is formed as a portion where no adhesive is applied, or a portion where an adhesive layer is formed and then folded to join the adhesive layers together. The vertical length d of the knob 4c is 5 to 15 mm, preferably 5 to 10 mm. If it is shorter than 5 mm, it is difficult to pick, and if it is longer than 15 mm, the knob 4 c tends to float and the tag tape 4 may be peeled off naturally.

The slip prevention means 5 provided on the back surface side of the sheet material 2 is provided in a substantially central portion with respect to the back surface side of the sheet material 2, and is intended to stop the displacement with the installation surface when the diaper changing sheet 1 is unfolded. It is intended to make it easier to open. In the illustrated example, the displacement preventing means 5 is provided at one central portion of the sheet material 2 in a horizontally long rectangular shape. However, the misalignment stopping means 5 is provided at a central portion of the sheet material 2 at a plurality of arbitrary shapes such as a circular shape. May be. The total area of the displacement preventing means 5 is 450 to 3500 mm ² . When it is provided in a substantially central portion in a rectangular shape as in the illustrated example, the width dimension is 30 to 70 mm, preferably 40 to 60 mm, and the vertical dimension is 15 to 50 mm, preferably 20 to 30 mm. As shown in FIG. 2, the misalignment stopping means 5 is at the center in the width direction between the fold lines L1 and L2 (B), and at a position closer to the lower side in the vertical direction between the fold lines L3 and L4 (D). It is preferable to provide it.

  Further, the displacement preventing means 6 is provided at the position corresponding to the position where the paper diaper 10 is disposed with respect to the back side of the sheet material 2, that is, on the lower side in the vertical direction where the paper diaper 10 is joined, and at the center in the width direction. This is intended to prevent misalignment between the sheet material 2 and the installation surface so that the sheet material 2 does not shift even if the child moves sometimes. The dimension and shape of the deviation preventing means 6 are the same as those of the deviation preventing means 5. If the displacement preventing means 6 is provided, the displacement preventing means 5 can be omitted. Further, when the diaper changing sheet 1 is folded in a three-fold state in the up-and-down direction (see FIGS. 6 and 7), the misalignment stopping means 6 is the surface side of the upper part of the sheet (when the shape of the sheet material 2 is rectangular) It can also be used as a joining means for maintaining the folded state of the diaper change sheet 1 by joining to the back side.

  The displacement preventing means 5 and 6 can be the above-mentioned mechanically-bonded fastening tape or a pressure-sensitive adhesive layer that can be releasably bonded. When the displacement preventing means 5 and 6 are formed of an adhesive layer, it is preferable that at least the displacement preventing means 5 is releasably covered with release paper. Alternatively, if the sheet material 2 itself is subjected to a peeling process with respect to the misalignment prevention means 6, when the diaper changing sheet 1 is folded in a tri-fold state in the vertical direction as described above, the surface of the upper portion of the sheet It can also be used as a joining means for maintaining the folded state of the diaper change sheet 1 joined to the side. However, in this case, if the shape of the sheet material 2 is a rectangle, the back surface of the sheet material 2 (the surface on the same side as the misalignment prevention means 6) is in contact with the misalignment prevention means 6, so that a partial peeling process is performed. If it is not applied, the pressure-sensitive adhesive layer of the slip prevention means 6 is easily peeled off from the sheet material 2. Here, when the sheet material 2 has the shape having the inclined sides 7 and 7, as shown in FIG. 7, a peeling process is performed on the front side surface of the sheet material 2 (the surface facing the displacement preventing means 6). For this reason, the entire front side surface of the sheet material 2 can be subjected to a peeling treatment, and the manufacture is easy. As the pressure-sensitive adhesive that forms the pressure-sensitive adhesive layer, for example, a material in which any one of a styrene polymer, a tackifier, and a plasticizer is a main component is suitably used. Examples of the styrenic polymer include styrene-ethylene-butylene-styrene block copolymers, styrene-butylene-styrene block copolymers, and styrene-isobutylene-styrene copolymers. It may be used or two or more polymer blends. Among these, a styrene-ethylene-butylene-styrene block copolymer is preferable in terms of good thermal stability. As the tackifier and plasticizer, those that are solid at room temperature can be preferably used. Examples of the tackifier include C5 petroleum resins, C9 petroleum resins, dicyclopentadiene petroleum resins, and rosin petroleum resins. Polyterpene resin, terpene phenol resin, etc., and examples of the plasticizer include monomer plasticizers such as trifresil phosphate, dibutyl phthalate, dioctyl phthalate, and polymer plasticizers such as vinyl polymers and polyesters. It is done.

  As the release treatment surface of the release paper or sheet material 2 covering the pressure-sensitive adhesive layer, a release treatment such as a silicone resin, a fluorine resin, or a tetrafluoroethylene resin is performed on the contact surface with the pressure-sensitive adhesive layer. Paper, non-woven fabric, or plastic sheet that has been liquid-coated or spray-coated and mold-released can be used. It should be noted that the film itself or the nonwoven fabric itself may be used as long as it does not cause a substantial decrease in the adhesive force without special release treatment.

  For example, as shown in FIG. 1, the paper diaper 10 has an absorbent body 13 made of cotton pulp or the like interposed between a liquid-permeable top sheet 11 and a liquid-impervious back sheet 12, and on both sides on the back side. It is a tape-type disposable paper diaper to which fastening tapes 14, 14 protruding sideways are attached. Moreover, although not shown in figure, the paper diaper 10 may be provided with the waistline expansion-contraction member which expands-contracts in the width direction at the back side edge part. The paper diaper 10 is detachably joined to the joining means 3 at least on both sides on the back side in a state where the diaper main body is folded in the front-rear direction. For this reason, the state in which the diaper changing sheet 1 is individually packaged is compact and convenient to carry. Furthermore, since only the back side portion of the diaper is joined and the stomach side portion of the diaper is not joined to the sheet material 2, the diaper attaching operation is facilitated.

The material constituting the back sheet 12 of the paper diaper 10 is preferably a non-liquid-permeable non-woven fabric made of polyethylene, polypropylene, or polyester fiber, and is a single material or a composite material. Such a non-woven fabric can be manufactured by an air-through method, a spunbond method, a spunlace method, a point bond method, an SMS method, or the like. Is preferred. In the spunlace method, there is a possibility that fibers are entangled with the bonded portion and difficult to remove. The basis weight of the back sheet 12 is 13 to 35 g / m ^2, and more preferably 17 to 25 g / m ² .

(Individual packaging procedure)
Next, the individual packaging procedure of the diaper changing sheet 1 will be described in detail with reference to FIGS. First, as shown in FIG. 4, the back side both sides and the back center of the paper diaper 10 in which the diaper main body is folded in the front-rear direction are detachably joined to the joining means 3, 3. Keep it.

  In this state, as shown in FIG. 5, the both sides in the width direction of the sheet material 2 are folded in three so as to overlap the central part together with the back side both sides of the paper diaper 10 at the positions of the folding lines L1 and L2, respectively. Fold in state.

  Next, as shown in FIG. 6, the lower portion of the sheet material 2 is folded together with the paper diaper 10 so as to overlap the central portion on the upper side at the fold line L3 position.

  Thereafter, as shown in FIG. 7, the tag tape is folded at the folding line L4 in the up and down direction so that the upper part of the sheet material 2 overlaps the upper surface thereof, and is provided at the opening edge. 4 is releasably joined to the outer surface of the sheet material 2 to hold the folded state.

(Opening procedure)
Next, a procedure for opening the diaper changing sheet 1 in the individually packaged state shown in FIG. 7 will be described in detail with reference to FIGS. 8 and 9. In order to open the diaper changing sheet 1, as shown in FIG. 8, the tab 4c of the tag tape 4 is picked and the folded state of the sheet material 2 is successively developed. Since the diaper changing sheet 1 according to the present invention is individually packaged by folding the sheet material 2 as described above, the diaper changing sheet 1 can be easily developed with one hand, and the paper diaper 10 is folded together with the sheet material 2. 9, when the sheet material 2 is unfolded, the paper diaper 10 is placed on the lower side in the center in the width direction, and the both sides of the back side of the paper diaper 10 are developed along with the unfolding of both sides of the sheet material 2. Are also automatically expanded. In addition, although it seems that the front body (upper part) of the diaper main body part folded in half is also automatically expanded, when it is not expanded by the folding fold, it is manually expanded.

(Modification of diaper changing sheet 1)
By the way, the said diaper change sheet | seat 1 can be comprised by deform | transforming with a various form. For example, as shown in FIG. 10, display lines 20 can be provided on the sheet material 2 in accordance with the arrangement position of the paper diaper 10. FIG. 10A shows the display line 20 aligned with the upper end of the paper diaper 10, and FIG. 10B shows the display line 20 along the outline of the paper diaper 10. By providing the display line 20, when a new paper diaper 10 is mounted on the diaper changing sheet 1, the set position of the paper diaper 10 can be easily understood.

  Further, as shown in FIG. 11, the sheet material 2 may be provided with mountain fold weirs 21, 21 projecting to the surface side along the vertical direction at substantially the side position of the diaper main body. Good. The weir 21 is formed by projecting the sheet material 2 into a triangular mountain shape on the surface side with a mountain fold at the middle along the vertical direction and a valley fold at both sides. The height Q of the inclined side from which the weir 21 protrudes is preferably 7 mm or more, particularly preferably 10 mm or more. If it is less than 7 mm, a normal amount of soft stool (about 60 cc) may leak out. In addition, you may make it provide the separate member which protrudes in the surface side as the said dam 21. FIG.

  The diaper changing sheet 1 may be a disposable type that is discarded after being used several times, or a repeating type that can be used repeatedly. In the case of the disposable type, the material constituting the sheet material 2 can be a single material or a composite material of materials used for ordinary packaging materials such as polyethylene, polypropylene, polyester, nylon, and nonwoven fabric. Among polyethylene, polypropylene, and polyester, a polyethylene film used for packaging sanitary goods is particularly preferable. Further, a softer material such as low density polyethylene (LDPE) or medium density polyethylene (MDPE) is preferable. In the case of such a disposable type, it is preferable to add a deodorizing function to the sheet material 2 because the odor can be reduced when the used diaper is wrapped and changed from whereabouts.

  On the other hand, in the case of the repetitive type, in addition to the materials listed as the disposable type, materials used for ordinary diaper changing sheets such as cotton and synthetic fiber can be used.

(Other)
