As shown in (a) in Fig. 3, front subsides 20 are divided into: middle section 20a; Region, left side side 20b, it is positioned at the left side side of this middle section 20a; Region, right side side 20c, it is positioned at the right side side of middle section 20a.In Fig. 3, in the example shown in (a), by the length trisection from left-hand end to right-hand end of front subsides 20, thereby these front subsides 20 are divided into middle section 20a, region, left side side 20b, region, right side side 20c.These regions that are divided are pasted each portion structure of 20 before for convenience of description and are divided in the conceptive region to these front subsides 20 and obtain, and are not limited to trisection.For example, the middle section 20a of front subsides 20, region, left side side 20b and region, right side side 20c can be divided according to the arbitrary ratio of 2:4:4,4:3:3 or 6:2:2.But, preferably equal in length on left and right directions of left side side region 20b and region, right side side 20c.
As shown in (a) in Fig. 3, it is long side direction that front subsides 20 are configured to left and right directions, the shape take above-below direction as short side direction.Front subsides 20 have the right side rim 206 of the lower rim 203 of the upper rim 201 of bending or bending, bending relative to upper rim 201 or bending, the left side rim 205 that connects the left part of upper rim 201 and the left part of lower rim 203, the connection right part of upper rim 201 and the right part of lower rim 203 substantially.
In addition, in Fig. 3, shown in (a) in example, front subsides 20 have upper end 202 on two positions of region, left side side 20b and region, right side side 20c.That is, from the upper end 202 that is positioned at region, left side side 20b along the left and right directions of subsides 20 while drawing straight line, just can on this straight line, find the upper end 202 that is positioned at region, right side side 20c.The upper end 202 of front subsides 20 at least belongs to either party of region, left side side 20b or region, right side side 20c, and each upper end 202 can exist difference of height on region, the left side side 20b of front subsides 20 and region, right side side 20c.
Upper rim 201 1 sides in front subsides 20 are formed with center cutout portion 21.By forming this center cutout portion 21, make upper rim 201 bend or bend.In Fig. 3, in (a), indicate the example of upper rim 201 bendings.It is recessed that 20 interior side direction pastes forward in center cutout portion 21, and this recessed top 211 is positioned at middle section 20a.In addition, the recessed top meaning refers to the position of the recessed amplitude maximum of formed otch.In Fig. 3, in (a), represent recessed top 211 with putting, but aftermentioned recessed top 211 can be linearly.In the time that recessed top 211 forms as point, preferably this recessed top 211 is positioned at the upper rim 201 center of front subsides 20.Recessed top 211 at least belongs to the region forming as middle section 20a, and this recessed top 211 can be by the distance of upper rim 201 center direction skew to the left and right regulation.
As shown in (a) in Fig. 3, preferably upper rim 201 is the curve that connects the recessed top 211 of center cutout portion and each upper end 202 of front subsides 20.In Fig. 3, in the embodiment shown in (b), each upper end 202 of front subsides 20 lays respectively at region, left side side 20b and region, right side side 20c is upper, and the recessed top 211 of each upper end 202 and center cutout portion is linked together by curve.As shown in (a) in Fig. 3, the curve that connects each upper end 202 and recessed top 211 can be mild alphabetical sigmoid curve, can be also mild circular-arc curve.
In Fig. 3, in the embodiment shown in (a), front subsides 20 upper ends 202 are inconsistent with the intersection point of upper rim 201 and each lateral margin (205,206).In other words the angle θ that, the tangent line of this upper rim 201 at the intersection point place of upper rim 201 and each lateral margin (205,206) and each lateral margin (205,206) form 1for obtuse angle (θ 1> 90 spends) for example, preferably θ 1angle be 95 degree～135 degree, 100 degree～130 degree or 105 degree～110 degree.In addition, (for example, as shown in (a) in Fig. 4) as hereinafter described, can make the upper end 202 of front subsides 20 consistent with the intersection point of upper rim 201 and each lateral margin (205,206).As shown in the embodiment that (a) in Fig. 3 represents, in the upper end 202 of front subsides 20 and the inconsistent situation of intersection point of upper rim 201 and each lateral margin (205,206), can utilize the curve of mild alphabetical S shape to connect the upper end 202 of front subsides 20 and the recessed top 211 of center cutout portion 201.Thereby before can forming, paste 20 whole upper rim 201 on this mild curve.Therefore, even in the case of the abdominal part of user and the upper rim 201 of front subsides 20 contact, also can prevent from user to cause unnecessary constriction.The upper end 202 of front subsides 20 can be for example 0.5mm～10mm, 1mm～8mm, 2mm～6mm or 3mm～4mm with the deviation (distance that symbol k is represented) of the intersection point of upper rim 201 and each lateral margin (205,206).
In addition, as shown in (a) in Fig. 3, the alphabetical sigmoid curve that connects the upper end 202 of upper rim 201 and the recessed top 211 of center cutout portion 21 is configured to and pastes 20 upper end 202 in the past and bloat the recessed shape in backward inner side towards outside to the recessed top 211 of center cutout portion 21., the upper rim 201 of front subsides 20 is made up of the curve of 2 alphabetical S shapes of Symmetrical Continuous.Thereby on the upper rim 201 of front subsides 20, form the recessed center cutout portion 21 of direction to the inside.
More particularly, the upper rim 201 of front subsides 20 is formed by 2 of Symmetrical Continuous mild alphabetical sigmoid curves.The mild curve meaning refers to respect to the angle of the tangent line of this curve and slowly changes, and for example preferably the angle variable quantity of tangent line is 1 degree～20 degree or 1 degree～10 degree.
The upper rim 201 of front subsides 20 is no more than the straight line that direction is extended to the left and right from upper end 202 degree to connect the alphabetical sigmoid curve of upper end 202 and recessed top 211 bloats laterally.In addition, the upper rim 201 of front subsides 20 is no more than from the degree of recessed top 211 straight line that direction is extended to the left and right recessed to the inside to connect the alphabetical sigmoid curve of upper end 202 and recessed top 211.In addition, connect the alphabetical sigmoid curve of upper end 202 and recessed top 211 in the case of comparing with the straight line that is connected upper end 202 and recessed top 211, show " bloating " and " recessed ".
As mentioned above, because the upper rim 201 of front subsides 20 is formed by 2 of Symmetrical Continuous mild alphabetical sigmoid curves, so, even for example in the prone situation of user, also can make the abdominal part of user and center cutout portion 21 fit.Therefore, by making alphabetical sigmoid curve connect upper end 202 and the recessed top 211 of left and right, even in the time that the abdominal part of user and the upper rim 201 of front subsides 20 contact, also can prevent from user to cause unnecessary constriction.
In addition, the bottom 204 in the lower rim 203 of front subsides 20 is positioned at middle section 20a, and in region, left side side, 20b is formed with lower left notch 22, and in region, right side side, 20c is formed with lower right notch 23.Lower left notch 22 forms by the lower left corner of cutting front subsides 20, and the recessed top 221 of lower left notch 22 is positioned at region, left side side 20b.Equally, lower right notch 23 forms by the lower right corner of cutting front subsides 20, and the recessed top 231 of lower right notch 23 is positioned at region, right side side 20c.Like this, by forming lower left notch 22 and lower right notch 23, the lower rim 203 of front subsides 20 is bent or bending.In Fig. 3, in (a), indicate the example of lower rim 203 bendings of front subsides 20.
In Fig. 3 in the embodiment of (a), when direction is drawn straight line to the left and right, just can roughly on this straight line, find the recessed top 231 of lower right notch 23 in the recessed top 221 from lower left notch 22.The recessed top 221 of lower left notch 22 and the recessed top 231 of lower right notch 23 can have difference of height on above-below direction.
As shown in (a) in Fig. 3, the bottom 204 of front subsides 20 is positioned at middle section 20a.Preferably bottom 204 is positioned at the central authorities of the lower rim 203 of front subsides 20, and still, this bottom 204 can, belonging in the scope of middle section 20a, be located on the position that is offset predetermined distance on left and right directions.

(2-3. absorber)
Absorber 31 is for absorbing the urine that keeps user.Absorber 31 is made up of absorbent material, to absorb the urine or the body fluid that keep user.As absorbent material, for example, can adopt Time of Fluff Slurry, high water absorbency polymer (Super Absorbent Polymer, " SAP "), high water absorption sheet material etc.Time of Fluff Slurry is for example to make it be the material that flocculence forms by wood pulp or non-wood pulp being carried out to fibrillation processing.High water absorbency polymer can be with adopting sodium polyacrylate.As hydrophilic sheet material, for example, can use the non-woven fabrics after napkin, absorbent paper, hydrophilic treated.
Absorber 31 is sandwiched between positive layer 32 and back layer 33, by the circumference of this positive layer 32 and this back layer 33 is sealed, absorber 31 is encapsulated between the two.The shape of absorber 31 is not limited to shape shown in figure, for example, can be rectangle, calabash shape, T-shaped.In the belt paper urine pants 100 shown in Fig. 1 and Fig. 2, adopt hourglass-shaped absorbent body as absorber 31.
(2-4. positive layer)
Positive layer 32 is the sheet material with permeability for liquids to configure from skin contact surface side covering absorber 31 modes.Positive layer 32 makes the liquid infiltration such as urine to being configured in the absorber 31 of its lower face side.
As the permeability for liquids material that forms positive layer 32, can adopt and spin cloth, non-woven fabrics, porous filler.Especially preferably adopt the non-woven fabrics being made up of polypropylene, polyethylene, polyester fiber, the such thermoplastic resin of nylon is carried out to the material after hydrophilicity-imparting treatment.
Positive layer 32 can be made up of single sheet material, also can be made up of multiple sheet materials.For example, can adopt by be configured in absorber surface element sheet material and be configured in the structure that the sheet material in flank part combines.
(2-5. back layer)
Back layer 33 has an impermeable sheet material of liquid for what configure in the mode that covers absorber 31 from non-skin contact side.Back layer 33 prevents the leak of liquid that kept by absorber 31 outside to diaper.
For example, as forming the liquid impermeability material of back layer 33, can adopt the liquid impermeability thin film that formed by resins such as polyethylene etc.Especially preferred microporous polyethylene film.This microporous polyethylene film is formed with the micropore of many 0.1 μ m left and right, has liquid impermeability but has poisture-penetrability, thereby can prevent that inside is sultry, therefore, preferably uses in this microporous polyethylene film as back layer 33.
In addition, in order to strengthen back layer 33, improve its feel, can on the outer surface of this back layer 33, paste bottom 36.As the material that forms bottom 36, for example, can use the non-woven fabrics or the wet nonwoven fabrics that are formed by polyethylene, polypropylene, the such thermoplastic resin of polyester fiber.
(2-6. stereo enclosure)
Stereo enclosure 35 plays a role as leakproof wall, for preventing that urine that user is drained etc. from leaking into the outside of diaper.Stereo enclosure 35 can be formed by the side facing 34 different with back layer 33 from positive layer 32.For example, by a distolateral surface that is fixed on positive layer 32 of side facing 34, and distolateral with the flexible material 41 of elongation state configuration stereo enclosure at another of this side facing 34.Thereby stereo enclosure 35 is erected under the telescopic action of the flexible material 41 of stereo enclosure, effectively prevent that the side leakage situation that the liquid such as urine spill from the leg opening part of diaper from occurring.
In order to prevent that the liquid such as urine from spilling from lower crosspiece part 3, stereo enclosure 35 is at least formed on lower crosspiece part 3, and still, this stereo enclosure 35 also can be formed in rear body side 1 and predecessor's side 2.In addition, stereo enclosure 35 at least forms a pair of in the side, left and right of lower crosspiece part, for example, and also can be at the square one-tenth of the left and right sides of lower crosspiece part more than 2 pairs.
(the various pads of 2-7.)
Preferably, in belt disposable paper urine pants involved in the present invention, except forming above-mentioned stereo enclosure 35, also form shank pad 37, waist pad 38.
The situation generation that shank pad 37 spills from the leg opening part of disposable paper urine pants for preventing the liquid such as urine.Along leg opening part, with the flexible material 42 of elongation state configuration shank, utilize the contractility of the flexible material 42 of this shank, form shank pad 37.Thereby around shank, be not easy to form gap, can effectively prevent that urine from spilling from leg opening part.In addition, if form shank pad 37, in the time changing diaper, the flexible material 42 of shank shrinks in the both sides of absorber 31, thereby makes whole lower crosspiece part 3 be deformed into bowl-shape.Therefore can make urine and body fluid stay and be formed as in bowl-shape lower crosspiece part 3, and easily in the situation that urine is not leaked, change diaper.
For example, the embodiment shown in Fig. 2 is following example: around the shank of disposable paper urine pants, configure the flexible material 42 of shank of 3 linearities along the long side direction (above-below direction) of diaper.The flexible material 42 of this shank is for example made up of rubber band or loose taut band.But the flexible material 42 of shank not necessarily will configure linearly, for example, can flexible shank material 42 be configured to curved shape along the curve of the leg opening part of diaper.
In addition, waist pad 38 spills from the waist opening portion of disposable paper urine pants for preventing urine, improves the stickiness of disposable paper urine pants, prevents that diaper from gliding.With the flexible material 43 of elongation state configuration waist, utilize the contractility of the flexible material 43 of this waist along waist opening portion, form waist pad 38.Thereby the waist opening portion of disposable paper urine pants and abdominal part and the back of user are close to mutually, are prevented urine leakage, improve laminating sense.
For example, the embodiment shown in Fig. 2 is following example: around the waist of disposable paper urine pants, along the flexible material 43 of 4 waists of short side direction (left and right directions) configuration of diaper.The flexible material 43 of this waist is identical with the flexible material 42 of shank, for example, be made up of rubber band or loose taut band.
The flexible material 43 of the flexible material 42 of above-mentioned shank and above-mentioned waist for example can adopt the rubber, elasticated net, stretched film, the elastic foam (polyurethane foam etc.) that are made up of natural rubber or the such elastomeric material of synthetic rubber (polyurethane rubber etc.).These elastomeric materials are fixed on other component parts of diaper by other modes beyond bonding agent.As fixing means, for example both can use heat molten type bonding agent, bonding agent that other mobility are higher to carry out bonding, can be again such the passing through heating or ultrasound wave etc. and carry out melting connection of heat-sealing.
(the 3. manufacture method of disposable paper urine pants)
The following describes the whole flow process of the manufacture method of belt disposable paper urine pants involved in the present invention.
First, on the upper surface of the longer back layer material of the material as back layer 33, place absorber 31.Then, on the upper surface of absorber 31, place the longer positive layer material as the material of positive layer 32.Thereby generate the continuous connected intermediate of disposable paper urine pants.Now, the longer side facing material as the material of side facing 34 can be sticked on positive layer material, then, on side facing material, configure the flexible material 41 of stereo enclosure, form stereo enclosure 35.
For the intermediate of the disposable paper urine pants that obtain like this, the part of the leg opening part that is equivalent to diaper is cut into circular-arc (cutting of R type), form leg opening part.Afterwards, the connecting band forming on other production lines 10 and front subsides 20 are sticked on respectively after in body side 1 and predecessor's side 2.Finally, one by one the intermediate of disposable paper urine pants is cut, thereby produce belt paper urine pants 100.
The manufacture method of front subsides 20 is described with reference to Fig. 9 below.
Especially example when below the upper rim 201 of subsides 20 and lower rim 203 are bending with same shape before explanation.
Fig. 9 is the figure that roughly represents the manufacturing process of front subsides 20.As shown in Figure 9, be positioned at the upstream of production line as the reel front subsides roller 52 that forms of the long front subsides material 51 of the material of front subsides 20.From this, subsides roller 52 pastes material 51 before extracting out, along direction shown in arrow A, this front subsides material 51 is sent to the downstream of production line.Cutting with rotor 53(on production line) be positioned at the downstream of front subsides roller 52.Cutting has rotating shaft with rotor 53, and rotates to direction described in arrow B.Cutting is carried out cutting to the front subsides material 51 being transmitted along production line with rotor 53 in the direction vertical with direction of transfer, thereby pastes 20 before forming one by one.
Here, cutting uses the cutting portion 54 of rotor 53 with the shape bending of the upper rim 201 corresponding to front subsides 20 and lower rim 203.Therefore, use 1 rotor 53 for cutting, just can carry out cutting to the upper rim of front subsides 20 201 and lower rim 203.Like this, as long as guarantee that upper rim 201 is consistent with the shape of lower rim 203, use cutting just can effectively produce front subsides 20 with rotor 23, thereby can reduce cost of manufacture, 20 speed is pasted in raising before making.
In addition, though the diagram of omission, cutting can and have at it and paste material 51 before clipping between anvil roller of flat surfaces and rotate with rotor 53, and this front subsides material 51 is carried out to cutting.
In addition, in the embodiment shown in Fig. 9, indicate the front subsides 20 that upper rim 201 and lower rim 203 form by curve.
In addition, for example, as shown in (d) in Fig. 4, upper rim 201 and the lower rim 203 of current subsides 20 are formed as straight line, and while there is the part that is level on left and right directions in a part for upper rim 201 and lower rim 203, the linear pressure in the part of this level and part in addition when cutting changes, so, in the time that front subsides 20 are carried out to cutting, may cause situation about can't cut to occur.
In this, shown in embodiment as shown in Figure 8, the upper rim 201 of current subsides 20 with in lower rim 203, do not exist in the embodiment of part of level on left and right directions (left and right directions is consistent with horizontal direction), in the time that front subsides 20 are carried out to cutting, the situation that is not easy can't cut.Especially, in the embodiment described in Fig. 8, the intersection point part of living in of the intersection point part of living in of upper rim 201 and each lateral margin (205,206) and lower rim 203 and each lateral margin (205,206) on left and right directions not in level.
Therefore, formed upper rim 201 and the lower rim 203 of front subsides 20 by curve, can solve the front problem occurring of pasting of cutting one by one at 20 o'clock.
