    [0001] The present invention relates to disposable garments, more specifically, disposable garments such as disposable diapers, disposable toilet training pants, panties for urinary incontinence, or the like.
    [0002] Disposable diapers that include an absorbent structure extended from a crotch region to the front and back waist regions and elastic bands attached to the front and back waist regions are known. For example, JP 2001-61890 A (LPT 1) discloses a disposable diaper in which elastic waist members are attached to the waist opening, and elastic waist members exert elasticity in regions where the absorbent structure is not positioned, while in a region in which the absorbent structure is positioned, the elasticity is not substantially exerted. [Patent Literature] [LPT1] JP 2001-61890 A
    [0003] LPT1 does not show what form the absorbent structure can take due to the contraction of the elastic members fixed in the waist regions.
    [0004] Some configurations of the present invention provide a disposable garment having a longitudinal direction and a lateral direction, including: one side facing the skin and one side not facing the skin opposite the other, front and back waist regions; a crotch region positioned between the frontal and posterior waist regions; a first waist panel defining the front and back waist regions and being elastically contractile in the lateral direction; a second panel that defines the other of the frontal and posterior waist regions and being elastically contractile in the lateral direction; a crotch panel extended between the first and second waist panels in the longitudinal direction to define a crotch region; and an absorbent body fluid structure positioned on the crotch panel.
    [0005] The body fluid-absorbent structure includes a liquid-absorbent core and a liquid-permeable cover sheet covering the core. The crotch panel is provided with first and second extreme panel edges extended in the lateral direction and joined to the side facing the skin of the first and second waist panels respectively. The core is provided with first and second extreme edges of the core extended in the lateral direction and at least the second extreme edge of the core overlaps with the second waist panel. The second waist panel is provided with an inelastic region defined in a region overlapping with the core. A first elastic region is formed outside the inelastic region in the lateral direction. A second elastic region is formed outside the inelastic region in the longitudinal direction. A distance between the second elastic region and the second extreme edge of the core is 5 to 20 mm.
    [0006] For a better understanding of the present invention, a detailed description of it will be made in relation to the attached drawings, presented in an exemplary and non-limiting character, in which: - Figure 1 is a perspective view of a diaper as an example disposable clothing items viewed from the side of the front waist region; Figure 2 is a perspective view from the side of the diaper; - Figure 3 is a plan view developed from the side facing the diaper skin; - Figure 4 is a plan view developed from a side not facing the skin of the diaper; - Figure 5 is a cross-sectional view along the line V-V of Figure 3; - Figure 6 is a diagram corresponding to Figure 4 in a worn state; - Figure 7 is a cross-sectional view of line VII-VII in Figure 3; Figure 8 is a partial diagram corresponding to Figure 7 in a worn state.
    [0007] Referring to Figure 1 to Figure 5 and Figure 7, diaper 1 includes a side facing the skin and a side not facing the opposite skin, a front waist region 2, a rear waist region 3, and a crotch region 4 extended between the frontal and posterior waist regions 2, 3. The diaper includes, in a developed flat view, an imaginary longitudinal central line PP dividing a dimension in a lateral X direction and an imaginary lateral central line QQ dividing a dimension in a longitudinal Y direction, and being symmetrical over the imaginary longitudinal central line PP. In Figures 3, 4, the respective elastics are shown in a stretched state against their contractile force.
    [0008] Diaper 1 also includes a front waist panel 20 defining the front waist region 2, a rear waist panel 30 defining the rear waist region 3, and a crotch panel 40 defining the crotch region 4 and extended to the regions front and rear waist 2, 3. Front waist panel 20 includes a front waist sheet 22 folded along a fold line 21 extended in the lateral direction C and front waist elastics 23 fixed between the folded front waist sheets 22. The front waist elastics 23 extend in the lateral direction C and are fixed in a contractile manner in a stretched mode and elasticize the front waist panel 20 in the lateral direction X. The folded front waist sheets 22 are fixed together by bonding means known as heat-melted adhesive through the front waist elastics 23.
    [0009] The rear waist panel 30 includes a rear waist sheet 32 folded along a fold line 31 extended in the lateral X direction and rear waist elastics 33 fixed between the folded rear waist sheets.
    [00010] The posterior waist elastics 33 extend in the lateral X direction and are contractually fixed in a stretched state in order to elasticize the posterior waist panel 30 in the lateral X direction. The posterior folded waist sheets 32 are fixed between itself by means of bonding known as heat-melted adhesive through the posterior waist elastics 33.
    [00011] These front and rear waist panels 20, 30 are annularly joined by a series of seams 5 formed along the side edges 20c, 30c, and thus forming a waist opening.
    [00012] As front and rear waist sheets 22, 32, for example, a continuous filament nonwoven material or a continuous filament nonwoven material (SMS), continuous filament blowing having a unit area by weight approximately 10 to 40 g / m2, preferably approximately 11 to 20 g / m2 can be used. As front and back waist elastics, a plurality of strands, cords, or elastic filaments may be used. For example, elastics of approximately 400 to 1200 dtex are arranged at a frequency of approximately 4 to 12 mm in the longitudinal Y direction in order to be fixed in a stretched radius of approximately 1.7 to 3.5.
    [00013] A crotch panel 40 includes: a side lining of the body 42 fixed on an absorbent side of the core 41; a leak barrier sheet 43 attached to the lower side of the core 41; an absorbent structure including core 41 and a cover sheet 49 to cover core 41; and a backsheet 44 to cover the side lining of the body 42 the leak barrier sheet 43 and to define the outer shape of a crotch panel 40. The side lining of the body 42, the leakage sheet 43 and the backsheet 44 have substantially the same dimension in the longitudinal direction Y, defining the extreme front and rear edges 40a, 40b of the crotch panel extended in the lateral direction X. the core 41 and the cover sheet 49 have smaller dimensions in the longitudinal direction Y than that of the leakage barrier sheet 43, the side lining of the body 42, the leakage barrier sheet 43 and the rear sheet 44. The front and rear end edges 41a, 41b of the core extended in the X side direction and the front and rear end edges 49a, 49b of the backing sheet. cover 49 extended in the lateral direction X being positioned more internally than the front and rear edges 40a, 40b of the crotch panel 40 in the longitudinal direction Y.
    [00014] The backsheet 44 is attached to the leakage barrier sheet 43 on the lower side of the core 41, extending outwardly from the lateral edges 41c of the core, and being folded towards the imaginary longitudinal centerline PP along the first fold line. 45 extended in the longitudinal direction Y to form a pair of first sheaths (joints) 46 spaced apart from each other in the lateral X direction. In addition, the backsheet 44 is folded externally in the lateral X direction along the second fold line 47 extended in the longitudinal direction Y at a point to overlap with the core 41, and thus forming a pair of second sheaths 48 spaced apart in the lateral direction X. In the first sheath 46, elastic joints 51 extended in the longitudinal direction are fixed contractile manner in a stretched state. The backsheets 44 are fixed together by means of joining known as heat-melt adhesive (not shown) in the first sheath 46. The first sheath is primarily capable of being in close contact with the thighs of the user (a), while the second sheath 48 is, inside the first sheath 46, primarily capable of being in close contact with the user's inguinal region or surroundings, and thus preventing excretions from leaking into the sides respectively.
    [00015] Elastic joints 51 are fixed so that the front end parts 51a overlap with the front waist region 2 and intersect with the front waist elastics 23, while the rear end part 51b overlaps with the waist region posterior 3 and intersect with the posterior waist elastics 33. The fact that the front and posterior extremities 51a, 51b intersect with the front and posterior waist elastics 23, 33 means that they are directly overlapped through the front waist sheets and rear 22, 32 and the rear sheet 44 to be intersected. With regard to elastic joints 51, the front and rear extreme edges 41a, 41b of the core 41 in the longitudinal direction Y, that is, that they are positioned on the side of the posterior lateral imaginary central line Q-Q. At least at the rear end 51b of the elastic joints 51, a dimension to the rear end edge 41b of the core 41 in the longitudinal direction Y is approximately 5 to 20 mm, preferably 7 to 15 mm.
    [00016] The second sheath 48 has a close edge part 48a attached to the side lining of the body 42 at the front and rear end parts of it and a distal edge part 48b attached to the side lining of the body 42 so that it is spaced out the same. In the part of the distal edge 48b, distal elastics 52 extend in the longitudinal direction YT and are contractually fixed in a stretched state.
    [00017] As core 41, pulp pulp of pulp, particles of super-absorbent polymer, or a mixture of them can be used. As cover sheet 49, liquid dispersion and liquid permeable sheet such as tissue paper or the like may be used. For example, hydro-interlaced non-woven material having a unit weight area of approximately 10 to 30 g / m2 can be used. The core 41 and the cover sheet 49 may be joined together by the use of bonding means known as heat-melt adhesive (not shown).
    [00018] As a side lining material of the body 42, for example, a continuous filament nonwoven material or a point bonded nonwoven material having a unit area by weight of approximately 15 to 35 g / m2, preferably 18 at 23 g / m2 can be used. As a leakage barrier sheet 43, a plastic or laminated film of the liquid impermeable and breathable film and a non-woven material may be used.
    [00019] As a backsheet 44, for example, a continuous filament non-woven material (SMS) having a unit area by weight of approximately 30 g / m2 can be used. As elastic joints 51, a wire, or cord or elastic tapes having approximately 400 to 1200 dtex can be fixed in a stretch radius of approximately 2.0 to 3.0. As distal elastics 52, a thread, cords or elastic bands having approximately 400 to 1200 dtex can be fixed in a stretched radius of approximately 2.0 to 3.0.
    [00020] With respect to the above crotch panel 40, the edge of the front end 40a is positioned on the side facing the skin of the front waist panel 20 and the back sheet 44 being joined to the front waist sheet by joining means known as adhesive heat-fused (not shown). At the same time, the edge of the front end 41a of the core 41 is also positioned in the front waist region 2 so that part of the core 41 is superimposed with the front waist panel 20. A dimension in the longitudinal Y direction of the core 51 overlapping with the front waist panel 20 being approximately 50 to 90 mm. In the region in which the core 41 is superimposed as described above, an inelastic region 61 in which the front waist elastics 23 are not positioned is formed. In addition, the inelastic region 61 may be formed by the arrangement of no front waist elastic 23. Furthermore, it may be formed after the continuous front waist elastics 23 are fixed between the side edges 20c of the front waist panel 20, the elastics being cut in the region overlapping with the core 41 so that the elastics are cut back and not exerting any elasticity.
    [00021] The outside of the inelastic region 61 in the lateral X direction, a first elastic region 62 is formed in a way that the elasticity of the front waist elastics 23 is exerted on it. The first elastic region 62 is partially overlapped with the core 41. This means that part of the front waist elastics 23 is fixed so as to overlap with the lateral edges 41c of the core 41, in which a dimension of the region overlapped in the direction lateral X will be approximately 15 to 35 mm. Accordingly, the contractile force of the front waist elastics 23 is exerted on the lateral edges 41c of the core 41.
    [00022] The outside of the inelastic region 61 in the longitudinal direction Y, a second inelastic region 63 being formed in such a way that the elasticity of the front waist elastics 23 is exerted on it. The second elastic region 63 is formed by the front waist elastics 23 being continuous between the side edges 20c of the front waist panel 20.
    [00023] Substantially in the entire region excluding the lateral edges 41c of the core above 41, the contractile force of the front waist elastics 23 is not exerted on the core 41, since the core does not shrink in the lateral X direction. Since folds are not formed in core 41, the area for contact with the user's skin (a) is not reduced.
    [00024] The edge of the rear end 40b of the crotch panel 40 is positioned on the side facing the skin of the rear waist panel 30 and the rear sheet 44 being joined to the rear waist sheet 32 by joining means known as heat-melt adhesive. (not shown). At the same time, the edge of the rear end 41b of the core 41 is positioned in the back waist region 3 so that part of the core 41 is overlapped with the back waist panel 30. A dimension of the core 41 in the longitudinal direction T overlapping with the rear waist panel 30 will be approximately 20 to 50 mm, which is less than that of the front waist panel 20. In the region in which the core 51 is superimposed as described above, an inelastic region 64 in which the rear waist elastics 33 are not positioned is formed.
    [00025] The outside of the inelastic region 64 in the lateral X direction, a first elastic region 65 is formed in such a way that the elasticity of the posterior waist elastics 33 is exerted on it. The first elastic region 65 is configured to partially overlap with the core 41. This means that part of the back waist elastics 33 is fixed so as to overlap with the lateral edges 41c of the core 41. More specifically, a dimension of the the region in which they are superimposed in the lateral X direction will be approximately 5 to 20 mm. Accordingly, the contractile force of the posterior waist elastics 33 is exerted on the lateral edges 41c of the core 41. However, the region in which the waist elastics 33 are overlapped with the lateral edges 41c of the core 41 in the posterior waist region 3 is to be lower than that of the frontal waist region 2.
    [00026] As illustrated in Figure 6, substantially in the entire core region 41 positioned in the posterior waist region 3 excluding the lateral edges 41c, since the contractile force of the posterior waist elastics 33 does not work in the core 41, the core 41 it does not shrink in the X lateral direction, so the area that can be turned towards the skin never decreases. Accordingly, it will be possible to prevent the absorption capacity of the decrease caused by a decrease in the area facing the skin. While the first elastic region 65 is in close contact with the user's skin by the contractile force, the inelastic region 64 is not in close contact with the skin, in which it curves with the lateral edges 41c as a point base to be spaced out of the user's skin. In particular, since at the side edges 41c of the core 41, the rear waist elastics 33 are superimposed on joins, their stiffness becomes greater in the vicinity of the side edges 41c than in other regions so that it becomes more easy to bend in the center of the core 41 having low stiffness in a direction spaced out of the skin. In the front waist region 2, since the region in which the front waist elastics 23 overlap with the side edges 41c is relatively large, the core 41 is pressed towards the user's skin by the contractile force of the elastics, and therefore , not spaced from the user's skin.
    [00027] Referring to Figure 4, Figure 7 and Figure 8, the outside of the inelastic region 64 in the longitudinal direction Y, a second elastic region 66 is formed in order to exert the elasticity of the posterior waist elastics 33. The second region elastic 66 is defined by continuous posterior waist elastics 33 between the lateral edges 30c of the posterior waist panel 30. A dimension between one of a plurality of posterior waist elastics 33 positioned, but close to the lateral of the crotch region of the core 41 in the direction longitudinal Y will be approximately 5 to 20 mm, preferably approximately 7 to 15 mm.
    [00028] Since the distance between the extreme rear edge 41b of the core 41 and the posterior waist elastics 33 positioned outside the same in the longitudinal direction Y being defined as above, as illustrated in Figure 8, when the posterior waist panel 30 contracts in the lateral X direction, the second elastic region 66 comes into close contact with the user (a), while the core 41 floats above the rear waist panel 30. At the extreme rear edge 41b of the core 41, a difference in stiffness it is made in the space of the rear waist panel 30, therefore a step part is formed in the rear waist panel 30 to which the rear extreme edge 41b is joined. In particular, since the elastic joints 51 extended in the longitudinal direction Y are superimposed at least with part of the elastics of the posterior waist 33, the crotch panel 40 is contracted in the longitudinal direction Y, so that a step can be more easily generated in the panel posterior waist 30.
    [00029] Core 41 curves in one direction to be spaced out of the user's skin (a) in the X lateral direction, and a step is formed by the posterior waist panel 30 at the posterior extreme edge 41b. Thus the core 41 and the rear waist panel 30 form a pocket 70 to retain excreta such as feces or the like. The excretions are temporarily retained in pocket 70, after which the fluid can be absorbed by the core 41. Thus, in particular, it will be possible to prevent loose stools with a high water content from leaking from the waist opening. By forming pocket 70, core 41 is spaced out of the user's skin so that it is possible to prevent core 41 from being in close contact with the user's skin through the side lining of body 42 causing moisture or diaper rashes.
    [00030] The second elastic regions 63, 66 of the front and rear waist panels 20, 30 are spaced apart from each other on the outside of the cover sheet 49 in the longitudinal direction. More specifically, the front and rear waist elastics 23, 33 attached to the second elastic regions 63, 66 do not overlap with the front and rear extreme edges 49a, 49b of the cover sheet 49. The front and rear extreme edges 49a, 49b are positioned on the innermost side than the front and rear waist elastics 23, 33 in the longitudinal Y direction. When a non-woven or similar material in which fibers are mechanically interwoven is used as the cover sheet 49, it may be a sheet having relatively high bending stiffness and the sheet may be difficult to contract even due to the contractile strength of the elastics. However, since the front and rear waist elastics 23, 33 do not overlap with the cover sheet 49, it will be possible to ensure that the front and rear waist panels 20, 30 contract and to keep them in close contact with the user's body. In addition, on the rear waist panel 30, the second elastic region 66 is ensured to be contracted, so pocket 70 can be easily formed.
    [00031] The front and rear waist panels 20, 30 include a double folded sheet that is formed by the rear fold of a piece of the sheet. At the extreme front and rear edges 40a, 40b of the crotch panel 40, only the side lining of the body 42, the leakage barrier sheet 43, and the rear sheet 44 are overlapped. Therefore, in the region in which these front and rear waist panels 20, 30 and the extreme front and rear edges 40a, 40b of the crotch panel 40 are superimposed, a relative small number of sheets, five in total, being overlapped.
    [00032] Since the number of overlapping sheets is small, the stiffness in this part is also relatively small, the front and rear waist panels 20, 30 are secured to contract by the contractile force of the front and rear waist elastics 23, 33.
    [00033] In this configuration, the front and rear waist elastics 23, 33 are not positioned in the inelastic regions 61, 64. However, if their elasticity is lower than that of the first elastic regions 62, 65 in order not to contract the core 41, the elastics can be fixed.
    [00034] It will be possible to generate stiffness between the central part of them, and the lateral parts, since the core 51 bends easily in the lateral X direction. X can be differentiated from that on the sides so that a difference in stiffness will be obtained. Core 41 may include a region (s) in which no or little core material is present. In addition, core 41 may be subjected to press work on the central or lateral part in order to obtain a difference in stiffness. In addition, a slit extended in the longitudinal direction Y or lateral direction X may be formed in the core 41 so as to be partially inferior in its stiffness.
    [00035] The crotch panel 40 is fixed with distal elastics 52, which motivate the second sheath 48 to contract in the longitudinal direction Y. Along with this, the integrality of the crotch panel 40 is contracted in the longitudinal direction Y. The vicinity of the extreme edge posterior 41b of core 41 is also contracted in the longitudinal direction Y, thus forming pocket 70 more easily. In this configuration, pocket 70 is formed in the posterior waist region 3, however, it can be formed in the frontal waist region 2 or in the frontal or posterior waist regions 2, 3.
