A=0 o'clock, be formed with the occasion of less perforate 32 in the diaper side portion, be fixed with the layer (with reference to the left part of Fig. 4) that constitutes around front and back waist zone 6,7 in the outer rim of perforate 32.In above-mentioned side portion, the 9B of position at least among adhesion part 9A, the 9B forms recess 33 at the front side and/or the rear side of side portion, and this recess 33 forms above-mentioned Roman character.Except above-mentioned Roman character, above-mentioned recess 33 also can form literal such as the hiragana, katakana, numeral, Chinese character of Japanese.Owing to can recognize these literal from the outside of diaper, so this literal can be used for following occasion, promptly it can represent the trade name of diaper, writes BOY or GIRL etc. to represent that this diaper is that boy uses or girl uses.
In order to form above-mentioned adhesion part 9A, 9B, the surface layer 2,3 that contains thermoplasticity synthetic resin composition can be overlapped, these layers 2,3 are carried out the local heat pressurization.In the heating pressurized portion, resin partly dissolves after fixing, and each layer 2,3 is shaped as one, thereby form thin membranaceous position 9A or 9B, at the non-pressurised position of non-heating, layer 2,3 keeps its original shape, thereby form thick non-adhesion part 31, consequently form recess 33.As shown in Figure 1, at a plurality of adhesion part 9A along in the vertically up and down zone of side portion, extend and closely amplexiform mutually and under the state of keeping parallelism towards the waistline direction, can prevent following situation, be that above-mentioned side portion produces as cardinal extremity with waistline opening 11 or leg openings 12 when wearing diaper and peels off, and along separate front and back.If the firmly adhesion in the manner described above of above-mentioned zone up and down is then close the territory, regional adhesioin zone about the adhesion zone of zone line up and down can not resemble.Can be more freely the spacing between the shape of the literal that adopted in zone line, size, the literal etc. be selected.If in the manner described above, the peel strength of zone line is reduced relatively, during the diaper 1 then peel off, taken off dirty, need not very big power, thereby concerning mother, be well suited in the front and back, edge.
Preferably should increase the thickness t of adhesion part 9B
BAnd the difference between the thickness T of non-adhesion part 31 so that can know the literal that identification is write by non-adhesion part 31 relatively on every side, and is easy to read this literal.But, because the thickness t of the adhesion part 9B of film like
BCan not increase, like this in order to increase above-mentioned thickness difference, in above-mentioned surface layer and the back layer 2,3 either party can adopt the non-woven fabrics with larger volume, thereby can increase the appearance thickness T of non-adhesion part 31.By the way, the thickness T of non-adhesion part 31 or the thickness of non-woven fabrics are the standards according to JIS L 1096, at 7gf/cm
2Pressurized conditions under measure the thickness t of above-mentioned adhesion part 9B
BMeasure by micrometer.The literal that reads easily also can obtain by light transmittance in adhesion part 9B and the non-adhesion part 31 or luminous reflectance are had than big difference.Such as, if on adhesion part 9B, form smooth surface and the higher relatively thin film of its light transmittance, non-adhesion part 31 only is that surface layer and back layer 2,3 overlap, its light transmittance is less than the analog value of position 9B, then position 9B becomes than position 31 transparencys or the higher position of translucence, and distinguish mutually, thereby be easy to read literal with non-adhesion part 31.Position 9B also can be the thin film with high light reflectance.
The present invention can implement in the following manner, this mode is: according to the mode of the diaper 1 of illustrated example, stratiform elastic component (la m) 3A is arranged at any one zone in the front and back waist zone 6,7 with extended state, on being in non-back layer 3 when wearing state, form many folds 22, in addition the present invention also can implement in the following manner, this mode is: replace above-mentioned stratiform elastic component 3A with banded elastic component, elastic component 3A is not set, and front and back waist zone 6,7 does not have fold 22 substantially.Even be formed with under the situation of many folds 22 on the layer 3 overleaf, shrink in the side portion free shrink or because of adhesion part 9A, 9B produce it owing to still can prevent la m 3A, can not produce fold 22 so substantially.No matter whether diaper is in the state of dress, is easy to recognize the literal that is written on the above-mentioned side portion.
The literal that is written on the adhesion part 9B can be replaced by printing word.Obviously to adopt the product harmless in the China ink of the printing usefulness of this moment, even should do one's utmost like this to prevent that above-mentioned graphite product from contacting with baby's mouth to baby safe.With regard to this respect, compare with the mode of printing, preferably draw by adhesion part 9B.
According to disposable diaper of the present invention, owing to form literal being difficult to produce on the side portion of fold, so no matter whether diaper is in the state of dress, all can recognize above-mentioned literal.
