BEST MODE FOR CARRYING OUT THE INVENTION
The details of the present invention will be described below with reference to the accompanying drawings, taking a disposable pants-type diaper as an example of a disposable pants-type wearing article.
[0010]
1 and 2 are a partially cutaway perspective view of a disposable pants-type diaper 1 in a worn state and a side view of the diaper 1 in a flat state. The diaper 1 has a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and an absorbent core 4 interposed between the two sheets 2, 3. It extends from the periphery and overlaps with each other via a hot melt adhesive (not shown). The diaper 1 also has a front waistline region 6, a rear waistline region 7, and a crotch region 8 located between the two waistline regions 6,7, and side edges of the front and rear waistline regions 6,7. 6a and 7a are overlapped in a palm shape with the topsheet 2 inside, and are joined at a portion 10 formed intermittently in the vertical direction in FIG. The diaper 1 further has a waist opening 12 and a pair of leg openings 13, and at the periphery of each of the openings 12, 13, the waist elastic member 16 and the leg elastic member 17 are front and back. It is interposed between the sheets 2 and 3 and is joined to at least one of the sheets 2 and 3 in an extended state. The diaper 1 has a wrapping sheet 20 extending between the side edge portions 6a outside the back sheet 3 in the front waistline region 6. The wrapping sheet 20 is substantially rectangular and has both side edges 20a, an upper edge 20b, and a lower edge 20c, and both sides 20a are integrated with both sides 6a of the front waist region 6; The upper edge 20b is integrated with the front waist region 6 at the edge 12a of the waist opening 12, so that the space between the lower edge 20c and the outer surface of the back sheet 3 opens downward from the diaper 1. Pocket (first pocket) 21 is formed.
[0011]
The wrapping sheet 20 has an inner surface 23 facing the back sheet 3 and an outer surface 24 on the opposite side of the inner surface 23. At the lower edge portion 20c, the outer surface 24 is folded back so as to be inside the pocket 21. A sleeve 26 is formed. Inside the sleeve 26, an elastic member 27 extends in an extended state between the side edge portions 20a of the wrapping sheet 20. The center of the wrapping sheet 20 in the width direction is on the center line C in the width direction of the diaper 1, and an adhesive tape piece 31 is attached to the inner surface 23 at the center. The tape piece 31 is folded in an N-shape or an inverted N-shape so that it can extend like a virtual line from the upper side to the lower side of the diaper 1 in the longitudinal direction thereof, and is provided with a wrapping sheet. A fixed end 32 that is non-peelably joined to the inner surface 23 of the base 20, a free end 33 that is opposite to the fixed end 32 and can be pinched, and the fixed end 32 and the free end 33; And an intermediate portion 34 interposed therebetween. Those skilled in the art may say that the tape piece 31 in which the respective portions 32, 33, and 34 are folded so as to overlap each other as shown in the figure is in a Z-folded or inverted Z-folded state.
[0012]
FIG. 3 is a view taken along line III-III in FIG. 1. In the figure, the tape piece 31 folded so as to exhibit an inverted N-shape is bonded so that the fixed end portion 32 does not peel off to the inner surface 23 of the wrapping sheet 20 via the first adhesive 41, An intermediate portion 34 is peelably joined to the fixed end portion 32 via a second adhesive 42 applied thereto. A third adhesive 43 is applied to a part of the surface where the free end 33 faces the intermediate part 34, and the free end 33 and the intermediate part 34 are peelably joined via the third adhesive 43. . The distal end portion of the free end portion 33 is a holding area 36, where the third adhesive 43 is not applied. Such a piece of tape 31 can be extended out of the pocket 21 as shown by the phantom line in FIGS.
[0013]
FIG. 4 is a perspective view when the soiled diaper 1 after use is rolled and wrapped by the wrapping sheet 20 and the adhesive tape piece 31. The soiled diaper 1 is rolled in FIG. 2 as follows. The diaper 1 is first overlapped with the front and rear waist regions 6 and 7 flattened so as to extend in the vertical direction in the figure, and the crotch region 8 is bent in the direction of arrow A so as to overlap the rear waist region 7. . Next, a pocket (second pocket) 52 is formed between the wrapping sheet 20 and the outer surface of the rear waistline region 7 so that the wrapping sheet 20 is turned over, and the crotch region 8 is accommodated in the pocket 52. Is folded back in the direction of arrow B. The inner surface 23 and the adhesive tape piece 31 are exposed in the folded wrapping sheet 20. When the tape piece 31 is pulled in the direction of the arrow C with the holding area 36, the parts that have been peelably joined are peeled off and released from the state of being folded in the N shape (or the inverted N shape). Then, the wrapping sheet 20 extends straight beyond the lower edge portion 20c. Since the third adhesive 43 is applied to the surface where the free end 33 of the extended tape piece 31 faces the diaper 1, the free end 33 of the tape piece 31 is attached via the third adhesive 43. At an appropriate site. The diaper 1 thus rounded by bending the crotch region 8 is closed so that the crotch region 8 is accommodated in the second pocket 52 and the mouth is not opened by the tape piece 31. As a result, the state shown in FIG. 4 is obtained. In the diaper 1 of FIG. 4, since the lower edge portion 20 c of the wrapping sheet 20 contracts elastically in the width direction of the diaper 1, the diaper 1 compactly wrapped by the wrapping sheet 20 is in a sealed state, and the diaper 1 The odor does not leak out.
[0014]
In the diaper 1 according to the present invention, since the adhesive tape piece 31 that fits inside the first pocket 21 is hidden inside the wrapping sheet 20, the tape piece 31 can be used by infants when the diaper 1 is worn. It is possible to avoid troubles such as being mischievously extended before use, or extending, causing dust to adhere to the surface of the third adhesive 43 and causing the third adhesive 43 to lose adhesive power in a substantial sense. be able to. Also in the production process of the diaper 1, the tape piece 31 does not hinder the diaper 1 from traveling at high speed as compared with the case where the tape piece 31 is attached to the diaper 1 so that it is exposed. In addition, the diaper 1 that is rolled up and stored in the second pocket 52 does not come out of the second pocket 52 due to the action of the tape piece 31, so that there is no possibility that a dirty portion will be exposed when discarded.
[0015]
In the diaper 1 of the illustrated example, a liquid-permeable nonwoven fabric or a perforated plastic film can be used for the topsheet 2. As the back sheet 3, a liquid-impermeable plastic film or nonwoven fabric, or a laminate sheet of a plastic film and a nonwoven fabric can be used. The core 4 may be made of ground pulp or a mixture of ground pulp and superabsorbent polymer particles.
[0016]
As the wrapping sheet 20, a portion in which the top sheet 2 or the back sheet 3 extends outside the diaper 1 from the edge of the waist opening 12 can be used, and in addition to the top sheet 2 or the back sheet 3, A moisture-permeable or moisture-impermeable plastic film or nonwoven fabric, a laminate sheet of a plastic film and a nonwoven fabric, or the like can be used. The wrapping sheet 20 is also capable of elastically expanding and contracting in the waist direction and / or the vertical direction of the diaper 1, and is compact so that the used diaper 1 is not small and easily spread. Preferably, it can be rolled up. Accordingly, the wrapping sheet 20 has a plurality of strips parallel to the elastic member 27 between the lower edge 20c and the upper edge 20b in addition to providing the elastic member 27 in an extended state at the lower edge 20c as shown in the illustrated example. An elastic member can be provided. The elastic member 27 extending in the waist direction allows the tape piece 31 to move in the length direction when at least one of the elastic members 27 crosses the fixed end 32 of the tape piece 31 or is located near the fixed end 32. When the diaper 1 is rolled while being strongly pulled, the wrapping sheet 20 tends to shrink in the waist direction and the vertical direction, so that the rolled diaper 1 is likely to be compact. Further, as the wrapping sheet 20, a sheet made of an elastomer can be used so that the entire sheet 20 can be extended and contracted in the waist direction and / or the vertical direction. The wrapping sheet 20 can be provided in the rear waist region 7 in addition to the front wrap region 6 as shown in the illustrated example. The dimension of the wrapping sheet 20 in the waist direction of the diaper 1 can be made smaller than this width in addition to the width of the front waist region 6 as shown in the illustrated example. The side edge portion 20a of the wrapping sheet 20 can be joined to an appropriate portion of the back sheet 3 in the front waistline region 6.
[0017]
The adhesive tape piece 31 attached to the wrapping sheet 20 can be made of a sheet material such as a plastic film or a nonwoven fabric. The tape piece 31 is folded so that the length direction thereof coincides with the up-down direction of the diaper 1 so that the holding area 36 is located near the lower edge 20 c of the wrapping sheet 20. When the diaper 36 is pulled downward to the diaper 1, at least a portion of the free end portion 33 where the third adhesive 43 is applied extends outside the lower edge portion 20c. In such a tape piece 31, the whole or a part (for example, the fixed end portion 32 or the intermediate portion 34) may be elastically expandable and contractable in the length direction of the tape piece 31.
[0018]
FIG. 5 is a drawing similar to FIG. 1 showing an example of the embodiment of the present invention. The diaper 1 has the same wrapping sheet 20 as in FIG. 1, but the adhesive tape piece 31 attached to the wrapping sheet 20 is in an inverted state so as to open downwardly of the diaper 1. It is folded so as to have a V-shape. The tape piece 31 has a fixed end portion 32 and a free end portion 33, and the fixed end portion 32 does not peel off at the lower end portion 32 a to the inner surface 23 of the wrapping sheet 20 via the first adhesive 41. On the other hand, the upper end portion 32b is not coated with the first adhesive 41 and is not joined to the inner surface 23. The free end portion 33 has a third adhesive 43 applied to a part of a surface facing the fixed end portion 32, and is joined to the fixed end portion 32 via the third adhesive 43 in a releasable manner. The distal end portion of the free end 33 is not coated with the third adhesive 43, and forms a holding area 36. In the diaper 1, the adhesive tape piece 31 is hidden inside the first pocket 21 formed by the wrapping sheet 20 and the front waist region 6, and as shown in FIG. A second pocket (not shown) formed by the tape piece 31 can be closed. 5 is bent at the boundary between the lower end portion 32a and the upper end portion 32b of the fixed end portion 32, and the upper end portion 32b and the free end portion 33 are straightened. It is possible to assume the shape and extend out of the first pocket 21 or the second pocket (not shown).
