  1 is a partially broken development view of a sanitary napkin 1 according to the present invention, FIG. 2 is a view taken along the line II-II, and FIG. 3 is a view taken along the line III-III in FIG.

  The sanitary napkin 1 is interposed between a back sheet 2 made of a polyethylene sheet, a polypropylene sheet, etc., a liquid-permeable surface sheet 3 that allows permeation of menstrual blood or cage, etc., and both the sheets 2 and 3. An absorbent body 4 made of cotton-like pulp or synthetic pulp, a crepe paper 5 surrounding the absorbent body 4 for maintaining the shape of the absorbent body 4 and improving diffusibility, and both sides of the surface along the longitudinal direction. The side nonwoven fabrics 6 and 6 are formed. Around the absorber 4, at the upper and lower edge portions thereof, the outer edge portions of the back sheet 2 and the liquid-permeable surface sheet 3 are joined by an adhesive such as hot melt or an adhesive means such as heat seal. The back sheet 2 and the side nonwoven fabric 6 that extend laterally from the absorbent body 4 at both side edges are joined by an adhesive such as hot melt or an adhesive means such as heat seal.

  In particular, in the sanitary napkin 1 according to the present invention, a pair of left and right wing-shaped flaps W, W disposed on both side portions of the main body portion where the absorbent body 4 is interposed between the top sheet 3 and the back sheet 2. However, at least three or more sets are arranged along the longitudinal direction of the main body portion, and in the illustrated example, four sets are arranged from the frontmost wing-shaped flaps W1 and W1 to the rearmost wing-shaped flaps W4 and W4 in order. In the illustrated example, among these wing-shaped flaps W, W..., The front three wing-shaped flaps W1 to W3 are wing-shaped flaps for fixing the crotch portion of the underwear to be wound, and are located at the rearmost portion. The pair of left and right wing-shaped flaps W4, W4 to be made are hip-hole wing-shaped flaps HF, HF with the flap absorbent bodies 4A, 4A surrounded by the crepe paper 5A. The flap absorber 4A can be arbitrarily interposed in the other wing-shaped flaps W1 to W3.

  The wing-shaped flaps W, W adjacent to each other in the longitudinal direction of the main body portion are divided in advance by a cut line 20 as shown in FIG. 1, or can be divided by a perforation 21 as shown in FIG. As shown in FIG. 12, the portion previously divided by the cut line 20 and the portion that can be divided by the perforation 21 are combined.

Hereinafter, the structure of the sanitary napkin 1 will be described in detail.
The back sheet 2 is made of a sheet material having at least a water shielding property such as an olefin resin sheet such as polyethylene or polypropylene. In addition to this, a laminated nonwoven fabric in which a nonwoven fabric is laminated on a polyethylene sheet or the like, and further a waterproof film is interposed. Then, after substantially ensuring liquid impermeability, a nonwoven fabric sheet (in this case, a waterproof sheet and a nonwoven fabric constitute the back sheet) can be used. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. This water- and moisture-permeable sheet material is a microporous sheet obtained by forming a sheet by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching in a uniaxial or biaxial direction. It is.

  Next, as the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and the spunbond method is excellent in drapeability, and the thermal bond method and air-through method are excellent in terms of being bulky and soft.

  The absorbent body 4 interposed between the back sheet 2 and the liquid-permeable top sheet 3 and the flap absorbent body 4A interposed between the back sheet 2 of the wing-shaped flap W and the side nonwoven fabric 6 are, for example, fluffs. It is comprised by the shape pulp and a water absorbing polymer. The water-absorbing polymer is mixed in the pulp constituting the absorber, for example, as granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length than hardwood pulp functions and It is preferably used in terms of price. When the crepe paper 5 surrounding the absorbent body 4 is provided as in this example, the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result. The crepe paper 5 which is excellent in diffusing body fluids quickly prevents reversal of menstrual blood and the like.

  On the other hand, side nonwoven fabrics 6 and 6 are provided on both sides of the sanitary napkin 1 along the longitudinal direction and almost the entire length of the napkin 1, respectively. Wings-like flaps W, W... Extending outward are formed by a part of the back sheet 2 that extends laterally and also laterally.

  The side nonwoven fabric 6 can use a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric for each wing-shaped flap W from the viewpoint of the function of each wing-shaped flap W. For example, the wing-shaped flaps W for entraining and fixing the crotch portion of the underwear, and in the example shown in FIG. 1, the three sets of wing-shaped flaps W1 to W3 on the front side prevent permeation of menstrual blood, cages, etc. If importance is placed on functions such as enhancing the feeling of touch, it is desirable to use a water repellent nonwoven fabric coated with a silicon-based, paraffin-based, alkylchromic chloride-based water repellent or the like. Moreover, the wing-shaped flap W used as the wing-shaped flap HF for hip holes, and the pair of left and right wing-shaped flaps W4 and W4 positioned at the rearmost portion in the example shown in FIG. In the synthetic fiber manufacturing process, a compound having a hydrophilic group, for example, a method of polymerizing in the presence of an oxidation product of polyethylene glycol, or treatment with a metal salt such as stannic chloride to partially dissolve the surface. It is desirable to use a hydrophilic treated non-woven fabric which is made porous by making the synthetic fiber swelled or porous by a method such as making it porous and depositing metal hydroxide, and applying hydrophilicity by applying capillary action. The side nonwoven fabric 6 can also be made of the same nonwoven fabric material for all the wing-shaped flaps W without being different for each function of each wing-shaped flap W.

  As shown in FIG. 1, the non-skin contact surface of the main body portion where the absorbent body 4 is interposed between the liquid-permeable top sheet 3 and the back sheet 2 is appropriately coated for fixing to the underwear. Depending on the pattern, one or a plurality of strips, and in the illustrated example, one strip of the main body displacement preventing adhesive layer 9 is formed in the central longitudinal direction of the sanitary napkin 1. Moreover, the wings prevention adhesive layer 10,10 ... is formed in the surface at the side of the back surface sheet 2 of the said wing-shaped flaps W, W ....

  As the pressure-sensitive adhesive that forms the anti-displacement pressure-sensitive adhesive layers 9 and 10, for example, a styrenic polymer, a tackifier, or a plasticizer whose main component is preferably used. Examples of the styrenic polymer include styrene-ethylene-butylene-styrene block copolymers, styrene-butylene-styrene block copolymers, and styrene-isobutylene-styrene copolymers. It may be used or two or more polymer blends. Among these, a styrene-ethylene-butylene-styrene block copolymer is preferable in terms of good thermal stability. As the tackifier and plasticizer, those that are solid at room temperature can be preferably used. Examples of the tackifier include C5 petroleum resins, C9 petroleum resins, dicyclopentadiene petroleum resins, and rosin petroleum resins. Polyterpene resin, terpene phenol resin, etc., and examples of the plasticizer include monomer plasticizers such as trifresil phosphate, dibutyl phthalate, dioctyl phthalate, and polymer plasticizers such as vinyl polymers and polyesters. It is done.

  As shown in FIGS. 4 and 5, all of the wing-shaped flaps W, W... Are folded from the fold line RL at the base end to the back sheet 2 side in the product state before use. Specifically, in the state of the product before use, each wing-shaped flap W, W... Is folded to the back sheet 2 side at the base end portion, and the front end side portion in the folded state is further folded back to the opposite side. And each of these folding parts is fixed to the main body part by temporarily fixing. The part temporarily folded from the base end part is easily fixed to the back sheet 2 by an adhesive such as hot melt or an adhesive means such as ultrasonic waves, and the part folded back at the tip side part is It is easily fixed to the wing-shaped flap W folded from the base end portion by an adhesive such as hot melt or an adhesive means such as ultrasonic waves. And the said wings prevention adhesive layer 10,10 ... is formed in the part of the back surface sheet 2 used as the outermost surface of this folding part. As a result, the wing-shaped flaps W, W before use are fixed to the main body portion of the sanitary napkin 1, and substantially the main body by the wings-stopping adhesive layers 10, 10 ... formed on the outer surface of the folded portion. An anti-displacement adhesive layer is formed on the part. For this reason, it is sufficient to form one piece of the adhesive stopper 9 of the main body portion in the central longitudinal direction of the sanitary napkin 1 as shown in the drawing, and the application efficiency of the adhesive stopper is improved. In order to secure the application width of such a shift preventing adhesive layer 9 of the main body portion, the extension length of the wing-shaped flap W to the outside from the folding line RL is 1/2 of the extension length. It is preferable to set it to 1/3 or less of the main body part width.

  When the sanitary napkin 1 configured as described above is fixed to the undergarment 30, as shown in FIG. 6, the sanitary napkin 1 is locally applied and any pair of left and right wing-shaped flaps W, W, In the illustrated example, the temporarily fixed state of the wing-shaped flaps W1 and W1 located at the foremost part is released and spread out from the underwear 30, and folded at fold lines RL and RL (see FIG. 1) at the wing-shaped flap W1 base end. The crotch part of the underwear 30 is attached and fixed to the outer surface of the crotch part of the underwear. Further, in the example shown in FIG. 7, the fixed position of the sanitary napkin 1 depends on the degree of menstrual blood flow of the wearer, usage conditions such as daytime and bedtime, or the shape and body shape of the underwear. When it is desired to change to, the pair of left and right wing-shaped flaps W2, W2 located in the second row is expanded and attached to the underwear 30 and fixed. As described above, the sanitary napkin 1 according to the present invention is a single sanitary napkin that can arbitrarily set the fixing position to the undergarment 30 according to various use conditions. For this reason, it is preferable that the main body portion of the sanitary napkin 1 according to the present invention is formed to have substantially the same width over the entire length.

  At this time, the wing-shaped flaps W, W,... That are not expanded and used are folded into the main body part as described above, and the wings-stopping adhesive layers 10, 10,. Therefore, it can be used as a misalignment-adhering adhesive layer that fixes the main body portion to the undergarment 30 together with the main-body misalignment-adhering adhesive layer 9.

  Further, as shown in FIG. 8, since the wing-shaped absorbers 4A and 4A are interposed in the wing-shaped flaps W4 and W4, respectively, the wing-shaped flaps W4 and W4 are widened to expand the hip-hold flaps HF, An HF can be formed, and the presence or absence of a hip-hold flap HF can be arbitrarily set. The sheet on the surface side of the wing-shaped flap W (side nonwoven fabric 6) that is the wing-shaped flap HF for hip holes can be embossed or waved in order to soften the contact with the skin. .

  The sanitary napkin 1 can be changed into various forms as described below. In the sanitary napkin 1 shown in FIG. 9, the wing-shaped flaps W and W can be divided by the perforation 21.
