Under the state that the surface patch 10 of absorbent commodity 1 remains on the inner side of package panel 70, along the predetermined folding line place folding absorbent article 1 of width W and length direction L and package panel 70.When absorbent commodity 1 is in folded state, a length direction end of package panel 70 is preferably attached to package panel 70.This length direction end of package panel 70 joins a part for package panel 70 to preferably by adhesive tape 75.
Then, the method for folding of the package body 100 of absorbent commodity is described.Fig. 4 to Fig. 6 is the axonometric chart of the folding step of the package body 100 schematically showing absorbent commodity.The folding step of the package body 100 of absorbent commodity comprises absorbent commodity and loads step, the first folding step, the second folding step, engagement step and the 3rd folding step.
Load in step at absorbent commodity, absorbent commodity 1 is disposed in package panel 70.The back sheet 20 of package panel 70 and absorbent commodity 1 is facing with each other.Noting, can be following structure: absorbent commodity 1 is disposed in and has in the package panel 70 of the size of individually packaged single absorbent commodity 1.Alternatively, such as, multiple absorbent commodity can be arranged in package panel along direction of transfer continuously by keeping predetermined interval between contiguous absorbent commodity.In the present embodiment, conveniently, utilize the package body having packed the absorbent commodity of single absorbent commodity so that method for folding to be described.
In the first folding step, as shown in Figure 4, by package panel 70 and absorbent commodity 1 edge area of a lateral edges from the width comprising absorbing articles 1 towards folded inside.With the first length direction folding line (see figure 1) FL1 of alongst L extension for basic point comes folding bag load 70 and absorbent commodity 1.In the second folding step, as shown in Figure 5, by package panel 70 and absorbent commodity 1 the opposite side edges region at the opposite side edge from the width W comprising absorbent commodity 1 towards folded inside.With the second length direction folding line (see figure 1) FL2 of alongst L extension for basic point comes folding bag load 70 and absorbent commodity 1.
Then, in engagement step, adhered in package panel 70 by the edge area of sticker 50 by the absorbent commodity 1 folded for basic point with the second length direction folding line FL2 and package panel 70.By this step, absorbent commodity 1 is individually packaged by package panel 70.Note, in the present embodiment, adhere to the edge area of the package panel 70 folded for basic point with the first length direction folding line FL1 and the second length direction folding line FL2 by means of sticker 50, but the edge area of package panel 70 can not be adhered to.In addition, the width end unit of package panel 70 can be adhered to by thermal welding, pressure bonding or ultrasonic fusing.
In the 3rd folding step, as shown in Figure 6, see Fig. 1 with the first width folding line FW1 extended along width and the second width folding line FW2() for basic point, by package panel 70 and absorbent commodity 1 from the two ends the length direction L of absorbent commodity 1 towards folded inside.Due to the execution of abovementioned steps, the folded and size of the package body 100 of absorbing articles reduces.
By folding by this way, absorbent commodity 1 can be packed compactly by package panel 70.Particularly, because drop to about 1/9, so absorbent commodity can be made compact with when absorbent commodity compares size with the situation that the plane domain of package panel launches.By reducing the size of absorbent commodity 1, when absorbent commodity 1 is incorporated in the such as bag such as little pocket or cabas, does not need large accommodation space in bag and can easily carry with.In addition, by wrapping up absorbent commodity 1 compactly, such as, when absorbent commodity is carried to toilet use, just with non-folded state, absorbent commodity 1 can be placed in hands, thus can carry carefully and do not noticed by others.
In addition, under the state that the package body 100 when folding absorbent commodity is opened, the first length direction folding line FL1 and the second length direction folding line FL2 is preferably positioned in inside the width of lateral plate 41 outside the width being present in absorber 30 and lateral plate 42.As shown in Figure 3, the first length direction folding line FL1 and the second length direction folding line FL2 is formed in the region of surface patch 10 and back sheet 20 overlap.First length direction folding line FL1 and the second length direction folding line FL2 is not overlapping with absorber 30 or lateral plate 41 and lateral plate 42 in the thickness directiont.Therefore, the fold caused due to the first length direction folding line FL1 and the second length direction folding line FL2 is only formed in surface patch 10 and back sheet 20.Usually, surface patch 10 and back sheet 20 have the rigidity lower than the rigidity of absorber 30.Be difficult to leave fold in surface patch 10 and back sheet 20.Note, the rigidity in description refers to the degree of the object resistance to deformation when attempting to make deformation of body by applying external force.Such as, rigidity is larger, and the degree of resistance to deformation is larger, and the fold stayed time folding is darker.
Therefore, be difficult to leave fold in the longitudinal direction, and when absorbent commodity 1 is worn in underwear, absorbent commodity 1 the heaving from underwear because folding line causes can be controlled.Finally, the fold that can prevent the folding line owing to extending along its length from causing and be difficult to launch the problem of absorbent commodity towards width.Wearer easily can arrange absorbent commodity along the inner surface of underwear, and can easily use wing unit by side, the noncontact face folding wings unit towards underwear, thus can improve dressing.
In addition, lateral plate 41 and lateral plate 42 are preferably arranged on outside the width of the first length direction folding line FL1 and the second length direction folding line FL2, and rigidity outside the width of the first length direction folding line FL1 and the second length direction folding line FL2 is high.Thus, due to the poor rigidity of the part outside the width of the part with the first length direction folding line FL1 and the second length direction folding line FL2 that are formed with the first length direction folding line FL1 and the second length direction folding line FL2, width both sides when opening the package body of absorbent commodity easily at absorbent commodity 1 are applied for the power opened, thus easily can launch absorbent commodity.
Sticker 50 is preferably disposed in inner side and/or outside relative to the first length direction folding line FL1 and the second length direction folding line FL2, instead of is disposed in region overlapping with the first length direction folding line FL1 or the second length direction folding line FL2 in the thickness directiont.Such as, by outside the width that the sticker 50 being used for bonding package panel 70 and absorbent commodity 1 is arranged on the first length direction folding line FL1 and the second length direction folding line FL2, when applying power when attempting launching absorbent commodity using the first length direction folding line FL1 and the second length direction folding line FL2 as basic point to package panel 70, power is applied to absorbent commodity along the direction of the width two side portions launching absorbent commodity 1, more easily launches absorbent commodity 1.
Wing unit 43 and wing unit 44 can have the thickness thinner than absorber 30 and relative being easier to forms fold.In addition, sticker can be arranged on the back side of wing unit 43 and wing unit 44, and when present dynasty is to the noncontact face folding wings unit 43 of underwear and wing unit 44, the sticker of both sides may cling, thus wing unit 43 and wing unit 44 fold may occur.But, because easily launch absorbent commodity, so can suitably towards spine folded wing unit 43 and wing unit 44, thus can prevent wing unit 43 and the wing unit 44 from producing the problem of fold.
(the second embodiment)
Then, the packaging 101 according to the absorbent commodity of the second embodiment is explained with reference to Fig. 7 and Fig. 8.Note, in the following explanation of present embodiment, the structure different from the first embodiment will be described and omit the explanation of the structure identical with the first embodiment.Fig. 7 is the plane graph observed from the skin contact side of the packaging 101 of the absorbent commodity according to the second embodiment, and Fig. 8 is the schematic sectional view along the Section B-B shown in Fig. 7.
Absorbent commodity 1A according to the second embodiment is different from the absorbent commodity 1 according to the first embodiment.Absorber 30 extends to outside the width of the first length direction folding line FL1 and the second length direction folding line FL2.Although it should be noted that and illustrate that absorber 30 comprises lower floor's absorber 31 and upper strata absorber 32, alternatively, absorber 30 only can comprise monolayer, namely can omit upper strata absorber 32.First length direction folding line FL1 and the second length direction folding line FL2 is overlapping with lower floor absorber 31 in the thickness directiont.In lower floor's absorber 31, be provided with the low rigid region LA that rigidity is lower than the rigidity of central part, the length direction L of described central part in absorber 30 and the central authorities of width W.In the figure 7, low rigid region LA is illustrated by shade.Note, central part is positioned at the length direction central authorities of absorber 30 and the part of width central authorities, and in the present embodiment, central part is the part being furnished with upper strata absorber 32.In addition, central part is configured to comprise the region contacted with excretory portion.Central part can be configured to have the high basic weight of part outside than central part.Such as, the basic weight of central part can be 400g/m
2to 800g/m
2.
Low rigid region LA is preferably configured to have the thickness less than the part being furnished with upper strata absorber 32 of absorber 30, preferably have than absorber 30 be furnished with the low basic weight of upper strata absorber 32 part.The rigidity of low rigid region LA is less than the rigidity of the part being furnished with upper strata absorber 32.Low rigid region LA is arranged at least overlapping with the first length direction folding line FL1 and the second length direction folding line FL2 in a thickness direction.More preferably, low rigid region LA is arranged on width W, stride across the first length direction folding line FL1 and the second length direction folding line FL2.Low rigid region LA width is in the direction of the width such as 2mm to 10mm, and more preferably, width is less than 5mm.Note, if low rigid region length is in the direction of the width more than 10mm, then may there is less desirable displacement in absorbent commodity in low rigid region LA.
With regard to the formation method of low rigid region, such as, when the pulp by stacked pulverizing manufactures absorber, protuberance can be set in the part corresponding with low rigid region of the plate building up pulp, profit in this way, only can reduce the thickness of absorber at protuberance.Note, web plate can be used as above-mentioned plate.By adjusting the thickness of protuberance, basic weight and the thickness of low rigid region can be adjusted.In addition, such as, by stacking multiple and the quantity only reducing stacked sheet at low rigid region constructs absorber, low rigid region can be formed.
According to the package body of the absorbent commodity so constructed, because the first length direction folding line FL1 and the second length direction folding line FL2 is formed in low rigid region, so be difficult to stay the fold of the absorber caused due to the first length direction folding line FL1 and the second length direction folding line FL2.
(the 3rd embodiment)
Then, the packaging 102 of the absorbent commodity according to the 3rd embodiment is explained with reference to Fig. 9.Fig. 9 is the plane graph observed from the skin contact side of the packaging 102 of the absorbent commodity according to the 3rd embodiment.The same with the absorbent commodity 1A according to the second embodiment, the absorbent commodity 1B of the 3rd embodiment is provided with the absorber 30 outside the width extending to the first length direction folding line FL1 and the second length direction folding line FL2, but the structure of low rigid region is different from the structure of the low rigid region of the absorbent commodity 1A according to the second embodiment.Although it should be noted that and illustrate that absorber 30 comprises lower floor's absorber 31 and upper strata absorber 32, alternatively, absorber 30 only can comprise monolayer, namely can omit upper strata absorber 32.
In absorber 30, be provided with the low rigid region that rigidity is lower than the rigidity of upper strata absorber 32.Low rigid region is the region being provided with slit 33 in absorber 30.Slit 33 is arranged discontinuously along the first length direction folding line FL1 and the second length direction folding line FL2.If slit 33 length in the longitudinal direction increases, be then difficult to the fold leaving absorber 30.But if slit 33 length is in the longitudinal direction oversize, then absorber 30 rigidity in the longitudinal direction may reduce.Thus, such as, expect that the length in the longitudinal direction between slit is more than 5mm.
The formation method of low rigid region such as comprises: form slit by being clamped in by absorber to comprise between the roller (upper axle) with sword and the pair of rolls of the roller (lower shaft) with groove.In addition, such as, when utilizing the stacked pulp of web plate to manufacture absorber, slit can be formed as follows: protuberance etc. is arranged on the part corresponding with slit and makes pulp that protuberance can not be accumulated in.
