[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging structure for absorbent articles that receives and absorbs body fluids such as sanitary napkins, panty liners, cage sheets, and incontinence pads.
[0002]
[Prior art]
For example, sanitary napkins are known that have overhanging portions projecting laterally on both sides, for example, so-called wing flaps.
In this type, the wing flaps on both sides are wrapped around the crotch part of the underwear (for example, panties), and the wing flaps are fastened to the outer surface of the underwear using a pre-adhesive layer, so that the napkin is displaced. It is intended to stop. In addition, it is also known to prevent misalignment by using a pressure-sensitive adhesive layer provided in advance on the back surface of the napkin body (the surface opposite to the use surface) to the underwear.
[0003]
[Problems to be solved by the invention]
However, it was found that the effect of preventing the wing flap from being displaced is not so effective for preventing the displacement due to the “swing” of the underwear accompanying active exercise.
In addition, when menstrual blood flows laterally from the side edge of the napkin, the wing flap is in a state where the crotch portion of the underwear is caught, so even if the wing flap has a function of preventing the crotch portion of the underwear from being soiled, side leakage It has been found that the prevention effect is not sufficient.
Therefore, the main subject of this invention is providing the packaging structure which can package suitably the absorptive article which overhang parts, such as a wing flap, exhibit a side-leakage prevention function.
Still another object is to provide an absorbent article or a packaging structure thereof in which the first adhesive portion and the second adhesive portion can be commonly covered with a covering material, particularly an outer sheet.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. In the present invention, the structure of the absorbent article itself is not limited as long as it has an overhanging portion that protrudes laterally from the main body portion (portion that mainly absorbs body fluid and is applied locally), Hereinafter, the packaging structure of the present invention will be described with reference to specific structural examples of absorbent articles.
[0017]
[First embodiment]
1 is a partially broken development view of a sanitary napkin 1A according to a first embodiment of the present invention, FIG. 2 is a rear view thereof, FIG. 3 is a view taken along the line III-III in FIG. It is an IV-IV line arrow directional view.
The sanitary napkin 1A includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet or the like, a liquid-permeable surface sheet 3 that allows permeation of menstrual blood or a cage and the like, and a space between these sheets 2 and 3. An absorbent body 4 made of cotton-like pulp or synthetic pulp intervening in the sheet, crepe paper 5 surrounding the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4, and longitudinally on both sides of the surface. It is comprised from the side nonwoven fabrics 6 and 6 formed along the direction, and the outer periphery of the said liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 in the upper-lower-end edge in the circumference | surroundings of the said absorber 4 The liquid-impervious back sheet 2 and the support which are joined to each other by an adhesive such as hot melt or an adhesive means such as heat seal and which extend laterally from the absorber 4 at both side edges. And de nonwoven 6 are joined by adhesive means such as adhesive or heat sealing, such as a hot melt.
[0018]
Hereinafter, the structure and materials of the sanitary napkin 1A will be described in detail. As the liquid-impermeable back sheet 2, a sheet material having at least water shielding properties such as an olefin resin sheet such as polyethylene or polypropylene is used. In addition, a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or a non-woven fabric sheet (in this case, a waterproof film and a non-woven fabric) A liquid-permeable back sheet is comprised.) Etc. can be used. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. It is a sheet.
[0019]
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 drapeability, and the thermal bond method is excellent in terms of being bulky and soft. In the illustrated example, the liquid-permeable surface sheet 3 has a two-layer structure including a porous plastic sheet 3A on the front surface side and a hydrophilic nonwoven fabric 3B on the back surface side.
[0020]
When the two-layered sheet is used as the liquid-permeable surface sheet 3, menstrual blood and urine (hereinafter collectively referred to as body fluid) are quickly absorbed, and the skin and The contact surface has excellent dry touch properties. In this case, as in this example, a crepe paper 5 surrounding the absorbent body 4 is provided, so that the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result. For example, the crepe paper 5 having excellent absorbability quickly diffuses body fluid and prevents reversal of these menstrual blood.
On the other hand, on the upper surface of the liquid-permeable surface sheet 3, side embosses 7 and 7 are formed on both sides of the blood drainage corresponding site, respectively along the substantially longitudinal direction, and arcuate embossing 8 and 8 is formed.
The absorbent body 4 interposed between the liquid-impervious back sheet 2 and the liquid-permeable top sheet 3 is made of, for example, fluffy pulp and a water-absorbing polymer. The water-absorbing polymer is mixed in the pulp constituting the absorber as, for example, 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.
[0021]
Now, in the unfolded state of the sanitary napkin 1A, side nonwoven fabrics 6 and 6 are provided on both sides of the front surface along the longitudinal direction and over almost the entire length of the absorbent article. A part of the side nonwoven fabrics 6 and 6 extends sideways, a part of the liquid-impermeable back sheet 2 extends sideways, and the side nonwoven fabric parts extending sideways are not A wing-like overhanging portion W, W is formed by joining the liquid-permeable backsheet portion with a hot melt adhesive or the like, and a first adhesive is attached to the surface of the wing-like overhanging portion W, W on the liquid-permeable surface sheet 3 side. Portions 10 and 10 are formed.
[0022]
As the side nonwoven fabric 6, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used from the viewpoint of important functions. For example, if importance is placed on functions such as preventing permeation of menstrual blood or vaginal discharge, or enhancing the touch feeling, water repellent treatment coated with silicon, paraffin or alkylchromic chloride water repellent If a non-woven fabric is used and if the importance of menstrual blood absorption in the wing-like overhanging portions W and W is emphasized, polymerization is carried out in the presence of a compound having a hydrophilic group, such as an oxidation product of polyethylene glycol, in the synthetic fiber production process. The synthetic fiber is made to swell or become porous by applying a method such as tantalum chloride or by treating it with a metal salt such as stannic chloride, partially dissolving the surface to make it porous, and depositing metal hydroxide. A hydrophilic treated non-woven fabric that has been rendered hydrophilic is used. For the purpose of the present invention, it is desirable to use a hydrophilic treated nonwoven fabric as the side nonwoven fabric 6.
[0023]
The side nonwoven fabric 6 can be made of natural fibers, synthetic fibers, regenerated fibers, or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 6 is made air permeable with a reduced basis weight. Nonwoven fabric should be used.
As shown in FIG. 3, the inner side of the side nonwoven fabric 6 is disposed with a predetermined width S1 on the inner side of the side edge of the absorbent body 4 so as to overlap with the inner side of the side edge by a few mm. S2 does not adhere to the liquid-permeable surface sheet 3, but exhibits a certain degree of standing toward the inside obliquely upward. As a result, even if the viscosity of the liquid-permeable topsheet 3 may flow on the surface of the liquid-permeable topsheet 3, the inner side edge portion (the S2 portion) that stands up to some extent becomes a barrier weir that prevents menstrual blood and the like. In addition to preventing side leakage, the menstrual blood or the cage absorbed by the absorbent body 4 by the side nonwoven fabric 6 is not transmitted to the outside from the side of the absorbent body 4 and bleeding is prevented. It is like that.
[0024]
<Example of packaging structure>
Now, a specific example of the packaging structure according to the present invention will be described. On the non-use surface side (back surface) of the liquid-impermeable back sheet 2, as shown in FIG. A plurality of second adhesive portions 11A and 11B are formed by the coating pattern of FIG. 5, and in the unused product state, for example, as shown in FIGS. 5 to 7, the wing-like overhanging portions W and W are folded to the back side. In the state, as a component of the covering material 50 that covers the first adhesive portion 10 and the second adhesive portions 11A and 11B in common, for example, a release sheet such as a release paper or a plastic sheet whose surface facing the back surface is siliconized It is covered with a material 51.
[0025]
The covering material 50 includes an outer sheet material 52 outside the release sheet material 51. The outer sheet material 52 is made of a material such as a plastic sheet or preferably a non-woven fabric having a good touch texture, and at least a part of the release sheet material 51, in the embodiment, in the middle part and the three regions before and after the longitudinal direction. , And substantially non-peelable by the joint portion 53 made of hot melt adhesive or the like. The joining force by the joining part 53 is larger than the joining force of the 1st adhesion part 10 and 2nd adhesion part 11A, 11B, and the peeling sheet material 51. FIG.
[0026]
Therefore, when packaging, the sanitary napkin 1A is covered with the release sheet material 51 (see FIG. 6) in a state where the wing-like overhanging portions W and W are folded to the back surface side, and the The outside is covered with a large outer sheet material 52 based on the outer shape of the sanitary napkin 1A (see FIG. 5). As shown in FIG. 7, the sanitary napkin 1 </ b> A is folded in the front-rear direction together with the outer sheet material 52, folded in, for example, a trifold, and opposed to one end of the outer sheet material 52, for example, the front end. The other part of 52 is temporarily fixed. Temporary fixing is performed by, for example, fixing the adhesive layer 54a formed on the inner surface of the protruding portion of the fastening tape 54 with the base fixed to one end portion of the outer sheet material 52 to the outer surface of the outer sheet material 52 on the rear side. It can be performed by adhering. Temporary fixing can also be performed by thermally welding the outer surface of the outer sheet material 52 on the rear side and the inner surface of one end portion of the outer sheet material 52.
[0027]
Further, the side portions of the folded outer sheet material 52 can be sealed to each other by a sealing means, for example, a heat seal portion.
In such a packaging structure, a user who has purchased the product picks up the protruding portion of the fastening tape 54 of the individual packaging bag and peels it off. At this time, the heat seal part is peeled off. At the same time, the release sheet material 51 joined through the joint portion 53 is also peeled off, and the first adhesive portion 10 and the second adhesive portions 11A and 11B are exposed.
[0028]
As shown in FIG. 8, the user applies the sanitary napkin 1 </ b> A locally, adheres it to the underwear S via the first adhesive portion 10, and the wing-like overhanging portions W and W projecting sideways. This is taken out from the underwear, and the wing-like overhanging portions W and W are adhered to the skin at the base of the crotch and thigh. As a result, the sanitary napkin 1A can be surely prevented from being displaced by the first adhesive portion 10 formed on the non-use surface side and the wing-like overhanging portions W and W directly bonded to the skin. Even if the amount of menstrual blood discharged to the sanitary napkin 1A is large and side leakage occurs and the wing-like overhanging portions W, W may occur, the menstrual blood etc. There is no need to worry about soiling the underwear and clothing because it does not come into contact with the underwear and clothing.
[0029]
Here, another example of the packaging form will be described. In the above example, the covering material 50 is separated from the release sheet material 51 and the outer sheet material 52. However, as shown in FIGS. Layer) sheet material 50A. That is, as the single sheet material 50A, a silicon-treated release paper, a polylaminated nonwoven fabric, a plastic sheet, or the like is used, and the release surface can be covered with the first adhesive portion 10 and the second adhesive portions 11A and 11B. it can.
On the other hand, the first adhesive portion 10 and the second adhesive portions 11A and 11B are covered with a common sheet. For example, as shown in FIG. 15, the first release sheet material 51A and the second release sheet are separately provided. It can be covered with the material 51B.
On the other hand, although not shown, the first release sheet material 51A and the second release sheet material 51B are joined, and preferably, the outer release sheet material and the outer sheet material 52 are joined, and the other It is possible to adopt an embodiment in which the release sheet material is not joined. Even in this case, when the outer sheet material 52 is peeled off, one release sheet material and the other release sheet material can be peeled together.
Further, the folding is not necessary, and the folding can be performed in two or more in addition to the three.
[0030]
As the pressure-sensitive adhesive that forms the pressure-sensitive adhesive layers 11A and 11B, for example, a styrenic polymer, a tackifier, or a plasticizer is preferably used as a main component. 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 the pressure-sensitive adhesive that forms the pressure-sensitive adhesive portion 10, an appropriate material that has no or little irritation to the skin can be selected.
[0031]
