Fig. 5 represents the enlarged drawing of the lateral side flap part in Fig. 1.Second junction surface 32 is configured to not overlapping with fixed component.Second junction surface 32 is arranged in lateral side flap 10 than the width regions WR extended in the width direction from fixed base end 21 by leaning on the position inside length direction outside length direction and than width regions WR.That is, the second junction surface is not overlapping with width regions.Further, the second junction surface 32 is arranged in the length areas LR that lateral side flap extends along its length from fixed base end 21.That is, the second junction surface is configured to, not overlapping with fixed base end 21 in the longitudinal direction, overlapping with fixed base end 21 in the direction of the width.
In addition, width regions WR is the region comprising fixed base end 21 and extend in the width direction from this fixed base end.In addition, length areas LR is the region comprising fixed base end 21 and extend along its length from this fixed base end.In Figure 5, mark different oblique lines to represent to width regions WR and length areas LR.
First junction surface 31 is configured in side base end part 11.First junction surface 31 is arranged on roughly whole side base end part 11.
The absorbent commodity of such formation is such as worn on wearer as follows.First junction surface is peeled off by wearer, and launches side folding portion.With the state expanding lateral side flap the front waist area S1 of absorbent commodity 1 is being attached to the veutro of wearer and under the state that the rear waist area S2 of absorbent commodity 1 is attached to the dorsal part of wearer, S1 layback in waist area is near forward by lateral side flap 10.Then, the fixing extension of fixed component is launched, exposes fixing holding section 23.The adhesive face of fixed component 20 is joined to the target portion 6A of front waist area S1, thus absorbent commodity 1 can be remained on the health of wearer.
In addition, when dressing, as mentioned above, fixed component is not launched together with lateral side flap, but by lateral side flap forward waist area S1 layback closely after launch fixed component, thus fixing holding section can be suppressed to stick to problem that position outside anticipation or fixing holding section touch the skin of wearer.
(2) manufacture method of absorbent commodity
Below, use Fig. 6, an example of the manufacture method of the absorbent commodity of present embodiment is described.In addition, in figure 6, for convenience of explanation, illustrate only the side in the side sheet that arranges respectively of left and right and lateral side flap.In addition, for method unaccounted in present embodiment, existing method can be used.In addition, the manufacture method below illustrated is an example, also can be manufactured by other manufacture method.The manufacture method of absorbent commodity at least comprises: the bonding process S11 of lateral side flap 10 and fixed component 20; The bonding process S12 of side sheet 4 and surface patch 5; The bonding process S13 of lateral side flap 10 and side sheet 4; Lateral side flap folding process S14; And absorber bonding process S15.
Fixed component 20 is joined to lateral side flap along its length on continuous print lateral side flap continuum 10C by lateral side flap 10 and the bonding process S11 of fixed component.Specifically, in the outboard end of the width of lateral side flap continuum 10C, engage fixed component 20.Then, lateral side flap continuum 10C is cut into the product length of lateral side flap, thus each lateral side flap 10 being bonded to fixed component 20 can be manufactured.
In addition, in the present embodiment, lateral side flap continuum 10C engages fixed component 20, but the outboard end that such as also can cut into the width of the lateral side flap 10 of product length at each engages fixed component 20.
In addition, lateral side flap 10 can use various method with the joint of fixed component, such as, can be engaged by bonding agent.In addition, the fixed component of present embodiment is on the face of the contact skin side being engaged with lateral side flap 10 and the face of non-skin contact side, as long as but at least one party joined in the face of the contact skin side of lateral side flap 10 and the face of non-skin contact side.
Then, side sheet 4 engages with surface patch by side sheet 4 and the bonding process S12 of surface patch.More particularly, by side sheet 4 along its length continuous print side sheet continuum 4C and surface patch along its length continuous print surface patch continuum 5C engage.Side sheet continuum 4C and surface patch continuum 5C is transferred on throughput direction MD alongst.Side sheet continuum 4C for basic point folds, between folded side sheet continuum 4C, is configured with leakproof elastic component 7 with broken line alongst.Like this face of the non-skin contact side along throughput direction continuous print side sheet continuum 4C is engaged with the face of the contact skin side of surface patch continuum 5C.
In addition, lateral side flap 10 does not limit with the order of the bonding process S11 of fixed component 20 and the bonding process S12 of side sheet 4 and surface patch 5.Such as, the bonding process S11 of lateral side flap 10 and fixed component can be also configured to carry out after the bonding process S12 of side sheet 4 and surface patch.
Then, in lateral side flap 10 with the bonding process S13 of side sheet, the lateral side flap 10 being bonded to fixed component 20 is engaged with side sheet 4.More particularly, relative to the face of the contact skin side of side sheet continuum, temporary fixed lateral side flap 10 discontinuously in the conveying direction.Temporary fixed is can peel off fixing.Specifically, be fixed into and before use lateral side flap 10 joined on side sheet 4 and can peel off in lateral side flap 10 from the side sheet 4 in use.Temporary fixed part between the skin contact of side sheet continuum 4C and lateral side flap 10 becomes the second junction surface.
Then, in lateral side flap folding process S14, by the end fold of lateral side flap 10 along the width of side sheet.Specifically, the non-skin contact surface side of the outboard end of the crisscross CD intersected with throughput direction of lateral side flap 10 to side sheet continuum 4C is turned down.Now, on the non-skin contact surface of side sheet continuum 4C, the part of the turnover of fixing lateral side flap 10.The non-skin contact surface of side sheet continuum 4C and the folding portion of lateral side flap 10 divide between standing part become the first junction surface 31.
Then, in absorber bonding process S15, by side sheet 4 and absorber integration.More particularly, the skin contact of absorber 3 is engaged with the side sheet 4 being bonded to surface patch continuum 5C and lateral side flap 10.By this operation, absorber 3, surface patch continuum 5C, lateral side flap 10, fixed component 20 and side sheet 4 are integrated.In addition, also before absorber bonding process, absorber and back sheet 6 can be engaged in advance, in absorber bonding process, absorber and back sheet engaged with the side sheet 4 being bonded to surface patch continuum and lateral side flap 10.Or, also can engage back sheet 6 after absorber bonding process.By joining back sheet to absorber, side sheet 4 etc., between side sheet 4 and back sheet, configure lateral side flap 10.
In addition, the operation configuring other member of formation such as leg elastic member, the operation etc. forming leg-openings portion can use known manufacture method to manufacture.
(3) effect
Because the side folding portion 13 of absorbent commodity joins in absorbent main body 2 via the second junction surface 32, therefore, it is possible to carry out the location of lateral side flap 10 and absorbent main body 2 during fabrication.In addition, because the lateral side flap 10 of absorbent commodity is folded under state before use, therefore, it is possible to receive absorbent commodity compactly, carry and become easy.
In addition, in use, the lateral side flap 10 of absorbent commodity is unfolded.Now, the second junction surface 32 of temporary fixed lateral side flap 10 be positioned at than width regions WR by outside length direction and than width regions WR by the position inside length direction, be not configured in width regions WR.Therefore, when launching lateral side flap 10, finger can be inserted in width regions WR, more preferably, finger can be inserted into the below of fixed component 20 to launch lateral side flap 10.
Further, in general, wearer hold fixed component 20 or its near launch lateral side flap 10.Now, when fixed component 20 is overlapping with the second junction surface 32, due to engaged position itself will be pulled, be therefore difficult to make it peel off.On the other hand, under fixed component 20 and the second nonoverlapping situation in junction surface 32, fixed component 20 can be held, with the second junction surface 32 for basic point launches lateral side flap 10.The distance of the fulcrum (the second junction surface) when the point (fixed component) due to force launches with lateral side flap is near, therefore easily makes it peel off.
In addition, in the mode that the second junction surface 32 is formed by adhesives, if be provided with the second junction surface 32 on fixed component 20, then sometimes also can remain bonding agent on the fixing element relieving under temporary fixed state (expanding the state of fixed component).
Fixed component 20 is for the component that wearer holds when absorbent commodity is dressed.If remain bonding agent on fixed component 20, then when operating, adhesives is attached on the finger of wearer etc. sometimes, produces discomfort.In addition, if remain bonding agent on fixed component 20, then likely when operating, fixed component 20 is attached to position outside anticipation, cannot be worn on correct position.
In addition, if be configured with bonding agent on the fixing element, then the direction can opened at fixed component when opening temporary fixed exerts a force.On the other hand, the absorbent commodity of present embodiment does not arrange the second junction surface on the fixing element, therefore, it is possible to suppress to exert a force on the direction that fixed component is opened when opening temporary fixed, and the opening and closing outside the anticipation that can suppress fixed component.
Second junction surface 32 is arranged in the length areas LR that lateral side flap extends along its length from fixed base end 21.Owing to being configured with the second junction surface 32 like this, therefore, the part being only bonded to fixed base end 21 is floated relative to absorbent main body, and wearer easily holds the position of inserting finger.Therefore, operability during use improves.In addition, if the fixed component supplying wearer to hold when lateral side flap is launched and the second junction surface 32 are from too far, be then difficult to exert a force to lateral side flap for basic point with the second junction surface 32.But, owing to being configured with the second junction surface 32 in the length areas adjacent with fixed base end 21, therefore, easily exerting a force to lateral side flap for basic point with the second junction surface 32, easily can launch lateral side flap.
The region disconnecting that second junction surface 32 is overlapping with fixing extension 22 and lateral side flap 10.Such as, when the region of fixing extension 22 and lateral side flap 10 overlap is temporary fixed by the second junction surface 32, not easily holds this fixing extension 22 and itself make the second junction surface 32 peel off.But, due to the region disconnecting that the second junction surface 32 is overlapping with fixing extension 22 and lateral side flap 10, therefore, it is possible to for the point that the holds distance with fulcrum when launching lateral side flap when guaranteeing to launch, easily launch.
Fixed component 20 is provided with multiple in each lateral side flap.Multiple fixed component 20 is separated in the longitudinal direction.The second junction surface 32 is configured with between multiple fixed component.Second junction surface 32 is configured in be leaned on the position outside length direction, position each other, fixed base end 21 than fixed base end 21, leans on the position inside length direction than fixed base end 21.Owing to being configured with the second junction surface 32 like this, therefore, the region being only configured with fixed base end 21 in the sidepiece of side folding portion 13 is floated relative to absorbent main body 2.Therefore, wearer easily holds the position of inserting finger.
Second junction surface 32 configures overlappingly with leakage-proof turnup.Therefore, side folding portion 13 temporarily anchors on the side sheet 4 of formation leakage-proof turnup via the second junction surface 32.When launching lateral side flap 10, the direction leaving absorbent main body 2 pulls side folding portion 13.Now, the side sheet 4 and the lateral side flap 10 that form leakage-proof turnup are not peeled off immediately, but peel off after leakage-proof turnup moves together with lateral side flap on the direction leaving absorbent main body.By making side sheet 4 move to wearer's layback together with lateral side flap 10 like this, leakage-proof turnup can be made to erect.
Second junction surface 32 has the length engaging zones 32A extended along its length and the width engaging zones 32B extended in the width direction, length engaging zones 32A and width engaging zones 32B alternately configure continuously.Shape during the overlooking of the second junction surface 32 is waveform.If such as adhesive-applying on whole of the first junction surface, then compared with the situation being coated into waveform, the coating weight of bonding agent is many, easily hardening.In addition, in order to reduce the coating weight of bonding agent, if such as adhesive applicating is become wire, then the area at the first junction surface diminishes, cannot stably temporary fixed lateral side flap and absorbent main body.By having the length engaging zones 32A extended along its length and the width engaging zones 32B extended in the width direction, thus the second junction surface has certain scope on width and length direction.The area at the second junction surface can be guaranteed, can stably temporary fixed lateral side flap and absorbent main body.
The second junction surface as temporary fixed portion be partial to front side or rear side compared with the length direction center of main body sheet configures.Be partial in the structure of front side compared with the length direction center of main body sheet at such as the second junction surface, the length at the second junction surface of side rearward, shorter than the length at the second junction surface of side forward compared with the length direction center of main body sheet compared with the length direction center of main body sheet.Therefore, the temporary fixed length of side is short rearward compared with the length direction center of main body sheet, can from the position of side easily temporary fixing lifting rearward compared with the length direction center of main body sheet.
Second junction surface 32 is configured to S1 side, front waist area length, S2 side, rear waist area is short, therefore easily launches lateral side flap.Specifically, when launching lateral side flap, be inserted into by finger between fixed component 20 and side sheet 4, the width tip inside of extension 12 gradually makes the second junction surface peel off towards the broken line FL side of lateral side flap from the side.Now, the S2 side, rear waist area of lateral side flap becomes peels off beginning position, therefore becomes and more easily launches.
