Description

The present invention relates to a method for manufacturing an absorbent article individually packaged with a packaging sheet.

  Conventionally, as an absorbent article N such as a sanitary napkin, a panty liner, a cage sheet, an incontinence pad, for example, as shown in FIG. 17, a liquid-impermeable back sheet 50 made of a polyethylene sheet or a polyethylene laminated nonwoven fabric, for example. And an absorbent body 52 made of cotton-like pulp or the like is known between a non-woven fabric or a liquid-permeable surface sheet 51 made of a porous plastic sheet.

  As this type of absorbent article N, in order to prevent misalignment in the mounted state, for example, one or a plurality of adhesive layers 53, 53 are formed on the non-skin contact surface side (outer surface), and the napkin body The wing-shaped flaps W, W extending outward are integrally formed on both sides in the longitudinal direction of the wing, and the wing-shaped flaps W, W are adhered to a surface (outer surface) on the liquid-impervious back sheet 50 side. There is one in which the agent layers 54 are provided.

  When fixing the absorbent article N to the undergarment 30, as shown in FIG. 18, the absorbent article N is locally applied, and the wing-shaped flaps W, W protruding sideways are taken out from the undergarment, The wing-shaped flaps W, W are folded at the folding lines RL, RL, and are adhered to the outer surface of the crotch portion of the underwear 30 while winding the crotch portion of the underwear.

  On the other hand, when the absorbent article N is individually packaged, the pressure-sensitive adhesive layers 53... 54 are covered with a release sheet made of paper or a film, and as shown in FIG. The packaging sheet 61 is arranged on the side, the napkin N, the release sheet and the packaging sheet 61 are tri-folded or quadrupled in the longitudinal direction, the side edge portion is heat-sealed, and the unsealed portion is fastened by the tag tape 60 (See, for example, Patent Document 1 below).

  In order to actually perform the above individual packaging on the line, as shown in FIG. 20, the wing-shaped flap W of the absorbent article that has been finished in the product state through the assembly process is conveyed by a sailor (folded plate) or the like during the transport process. After folding to the non-use surface side (back sheet side) or the use surface side (surface sheet side), the plane is inverted 90 ° and the individual sheet 61 is introduced to the liquid-impermeable back sheet side, and then the sailor The front end portion and the rear end portion located on the left and right sides together with the individual sheet 61 are folded in order, and the opening edge of the individual sheet 61 is sealed and cut by the tag tape 60 supplied from the tag tape drum. (See, for example, Patent Document 2).

Japanese Patent Laid-Open No. 9-94267 JP 2004-121299 A

  As the tag tape 60 for sealing the opening edge of the packaging sheet, paper or plastic tape or the like is conventionally used as shown in FIG. 21, and a peelable adhesive layer is formed on one side. The tip portion was doubled as a non-adhesive portion and used as a knob portion 60a for peeling.

  However, the tag tape supplied from the tag tape drum is likely to be misaligned in the direction perpendicular to the line due to meandering, vibration, etc., and the folding position fluctuates when the tape is folded to provide a non-adhesive part serving as a knob. For this reason, a sufficient adhesive length cannot be secured, and there are problems such as a decrease in adhesive strength in the product state and difficulty in stopping when the used absorbent article is packaged with a packaging sheet and discarded.

  Further, in the individual packaging line as described above, the end of the tag tape 60 needs to be folded back by a sailor while being fed along the line, and the napkin is fed vertically and then folded and fixed to the tag tape 60. Therefore, it was necessary to reverse 90 ° to create a lateral flow. However, the 90 ° inversion has a problem in that each napkin is liable to cause a pitch shift, which causes the yield to deteriorate.

Therefore, the main problem of the present invention is to wrap an absorbent article in which an absorbent body is interposed between a liquid-permeable top sheet and a back sheet with a packaging sheet, and to absorb the individual packaging with the opening side edge fastened with a tag tape. In the method for manufacturing a property article, the tag tape can be easily opened, and a sufficient adhesive length can be secured to the tag tape even if there is a positional shift or a change in the folding position. . Another object of the present invention is to assemble the absorbent article as it is in the longitudinal flow in the production line so that the folding process can be performed while maintaining the longitudinal flow.

In order to solve the above-mentioned problem, as the present invention according to claim 1, an absorbent article in which an absorbent body is interposed between a liquid-permeable top sheet and a back sheet is wrapped with a packaging sheet, and an opening side edge is tagged. In the manufacturing method of the individual absorbent article fixed by the tape,
In the tag tape, a non-adhesive knob is formed on a side edge portion orthogonal to the direction of the opening side edge on the adhesive surface side with respect to the packaging sheet, and the absorbent article is assembled in the production line while being longitudinally flowed. The folding process is performed together with the packaging sheet in the longitudinal flow, and the opening side edge of the packaging sheet is orthogonal to the production line direction and is fastened by the tag tape supplied from the production line direction. The manufacturing method of the individual absorbent article characterized by these is provided.

  In the present invention according to the first aspect, the tag tape is formed with a non-adhesive knob on the side edge portion orthogonal to the direction of the opening edge on the adhesive surface side with respect to the packaging sheet. Accordingly, the individual absorbent article can be held with one hand, and the tag tape can be peeled off with the fingers of one hand from the side to be opened. In the case of this peeling mode, it becomes easier to insert a finger from the side of the tag tape, especially in the case of an individual absorbent article that is not center-sealed on the opening side edge or a narrow individual absorbent article. It becomes easy to do.

  In addition, because the non-adhesive part is formed on the side edge of the tag tape, even if the folding position fluctuates slightly or the mounting position fluctuates, the positional deviation occurs in the direction of the opening side edge. Since a sufficient adhesive length is secured, it is easy to stop the tag tape when the used absorbent article is wrapped in a packaging sheet and discarded as well as the product state. Further, in the case of a mode in which a non-adhesive portion is formed on the side edge portion of the tag tape, the forming direction of the non-adhesive portion is the production line direction. Folding processing is performed as it is, and it is sufficient to fasten with the tag tape. Therefore, problems such as a decrease in yield due to 90 ° inversion can be solved.

According to a second aspect of the present invention, there is provided a method for producing an individually absorbent article according to the first aspect, wherein the non-adhesive knob is formed on both sides or one side of a tag tape. The non-adhesive knob for the tag tape can be formed on both sides or one side of the tag tape.

As an aspect of the present invention according to Claim 3, an enlarged portion of a non-adhesive range extending in the width direction of the tape from the non-adhesive portion is formed in an intermediate portion of the tag tape. A method of manufacturing a individually absorbent article is provided.

  According to the third aspect of the present invention, an enlarged portion of a non-adhesive range extending in the width direction from the non-adhesive portion is formed in an intermediate portion of the tag tape. Therefore, the tag tape can be easily peeled by inserting a finger up to the non-adhesive enlarged portion.

  As described above, according to the present invention, the tag tape can be easily opened, and a sufficient adhesion length can be secured to the tag tape even if the position shift or the turn-back position varies. In addition, since the absorbent article can be assembled in the production line in the longitudinal flow and folded in the longitudinal flow, problems such as a decrease in yield can be solved.

[Structural example of absorbent article]
FIG. 1 is a partially broken development view of a sanitary napkin 1 according to the present invention, FIG. 2 is a rear view thereof, and is a view taken along the line III-III of FIG.

The sanitary napkin 1 includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, etc., a liquid-permeable front sheet 3 that allows permeation of menstrual blood, cages, etc. 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. Around the absorber 4, at the upper and lower edge portions, the outer edge portions of the liquid-impervious 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. In addition, the liquid-impervious backsheet 2 and the side nonwoven fabric 6 that extend laterally from the absorbent body 4 at both side edges thereof are joined by an adhesive such as hot melt or an adhesive means such as heat seal. Has been. In the present specification, the flap portions at both side edges are referred to as “side outer peripheral flaps F _S ”.

Hereinafter, the structure of the sanitary napkin 1 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 nonwoven fabric sheet (in this case, the waterproof film and the nonwoven fabric constitute a liquid-impervious back sheet) can be used after substantially impervious to liquid imperviousness by interposing a waterproof film. 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 drapeability, and the thermal bond method is excellent in terms of being bulky and soft. 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, for example, as granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolved 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. Wing-like flaps W, W are formed by a part of the liquid-impervious back sheet 2 that extends sideways and also extends sideways.

  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 It is desirable to use a nonwoven fabric. Further, if importance is attached to the absorption of menstrual blood and the like in the wing-shaped flaps W, W, a method of polymerizing a compound having a hydrophilic group, for example, an oxidation product of polyethylene glycol, in the process of producing a synthetic fiber, , By treating with a metal salt such as stannic chloride, partially dissolving the surface to make it porous, and depositing metal hydroxides to swell or make the synthetic fiber porous, applying capillary action to make it hydrophilic It is desirable to use a hydrophilic treated non-woven fabric provided with.

  As shown in FIG. 2, the non-skin contact surface of the main body part in which the absorbent body 4 is interposed between the liquid-permeable top sheet 3 and the liquid-impervious back sheet 2 is for fixing to the underwear. A plurality of main body displacement prevention adhesive layers 9, 9... In the illustrated example are formed by an appropriate application pattern, and the main body displacement prevention adhesive layers 9, 9. Covered by. The wing-shaped flaps W, W are formed on the liquid-impervious back sheet 2 side with wings-stopping adhesive layers 10, 10, and the wings-stopping adhesive layers 10, 10 are wide. It is covered with one wing release material 12 that crosses in the direction. The main body release material 11 and the wing release material 12 are firmly fixed and integrated by a hot melt adhesive or the like in a region surrounded by a chain line 13. In this example, one release material is used as the release material 12 that covers the wings-stopping pressure-sensitive adhesive layers 10, 10.

  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 the release materials 11 and 12, for example, a release treatment liquid such as a silicone resin, a fluorine resin, or a tetrafluoroethylene resin is applied to the contact surfaces with respect to the slip prevention adhesive layers 9 and 10. Alternatively, paper or plastic sheet that has been spray-coated and release-treated can be used. It should be noted that the film itself or the nonwoven fabric itself may be used as long as it does not cause a substantial decrease in the adhesive force without special release treatment.

[Instructions for individual napkin 1]
To individually packaged sanitary napkin 1 described above, as shown in FIG. 4, one of the wing-shaped flaps W outside the vicinity of the absorbent body 4 side edges as a line, including the side periphery flaps F _S, after folding the liquid-permeable surface sheet 3 side together with release material 12 wings, the other wing-shaped flaps W outside the vicinity of the absorbent body 4 side edges as a line, including the side periphery flaps F _S, stripping wings Fold together with the material 12 to the liquid-permeable surface sheet 3 side. Alternatively, as shown in FIG. 5, one of the wing-shaped flaps W as a line outside the vicinity of the absorber 4 side edges, including the side periphery flaps F _S, liquid-impermeable back sheet together with the wing release material 12 after folding two side, the other wing-shaped flaps W outside the vicinity of the absorbent body 4 side edges as a line, including the side periphery flaps F _S, liquid-impermeable back sheet 2 side together with the wing release material 12 Fold it down.

  In this case, it is desirable to hold the folded state of the wing-shaped flap W by the shape-retaining means. Specifically, as the first means, a paper material having a certain degree of stiffness can be used as the wing release material 12, and the folded state can be maintained by the folds. The second means can be temporarily attached and held by any one of hot melt, heat seal, and ultrasonic seal. Similarly, it is desirable that the overlapping portion of the wing-shaped flaps W, W is temporarily held by any one of the hot melt, heat seal, and ultrasonic seal.

  When the wing-shaped flaps W, W are folded on the front side or the back side, the sanitary napkin 1 is individually mounted with the individual sheet 14. The explanation and the illustrated example are cases where the wing-shaped flaps W, W are folded on the front side, but the same can be done when the wing-like flaps W are folded on the back side.

  As shown in FIG. 6, the width dimension is narrower than the developed width of the napkin 1 (the distance between the tips of the wing-shaped flaps W, W) and is wider than the folded state of the wing-shaped flaps W, W. The napkin 1 is arranged on the individual sheet 14 so that at least the opening side edge 14a of the individual sheet 14 is positioned outside one of the front and rear end portions of the napkin 1 by the individual sheet 14 having the length, The individual sheet 14 and the main body release material 11 and / or the wing release material 12 are firmly fixed by a hot melt adhesive or the like.

  After that, if the napkin rear end side is folded at the fold line (1) position, the napkin front end side is folded at the fold line (2) position, and as shown in FIG. The side edge portions 14b and 14b thus formed are sealed by an appropriate sealing means such as embossing pressure bonding, heat fusion, and adhesive. Moreover, the opening side edge 14a of the individual packaging sheet 14 is preferably sealed with a tag tape 15 after being joined with an adhesive.

In the above example, wing-shaped flaps W include side outer peripheral flap F _S, has been to fold the W, wing-shaped flaps W, W moiety only as folded on the topsheet 3 side or the back sheet 2 side May be.

  As shown in FIG. 8, the tag tape 15 is a member made of paper, plastic film, or the like. As shown in FIG. The knobs 15a and 15a are formed, and the middle part is an adhesive surface 15b. The pressure-sensitive adhesive forming the pressure-sensitive adhesive surface 15b is the same as the pressure-sensitive adhesive forming the anti-displacement pressure-sensitive adhesive layers 9, 10, or the one with appropriate changes. The non-adhesive knob portion 15a is formed by applying the adhesive to the entire surface of one side of the tape base material, or in the step of feeding the adhesive tape to which the adhesive has been applied in advance. It can be formed by folding back and can be formed by adhering other materials to the side edge portion. Moreover, it can form also by apply | coating an adhesive so that an adhesive may not be apply | coated to the non-adhesion part 15a.

  The knob 15a may be formed on both side edge portions as shown in FIG. 8, or may be formed only on one side edge as shown in FIG. Furthermore, an enlarged portion of a non-adhesive range extending in the width direction from the non-adhesive portion can be formed in the intermediate portion of the tag tape 15. Specifically, as shown in FIG. 10 (A), the non-adhesive portion 15c is formed so as to cross the tape 15 at the intermediate portion of the tag tape 15, and FIG. FIG. 10C shows an example in which a bulging-shaped non-adhesive portion 15 c is formed extending from one non-adhesive knob portion 15 a in the intermediate portion, and FIG. 10C shows both non-adhesive knob portions 15 a in the intermediate portion of the tag tape 15. In this example, the non-adhesive portions 15c and 15c having a bulging shape are formed respectively extending from the bulge.

  To open the individual napkin, as shown in FIG. 11, hold the individual napkin with one hand, peel off the tag tape 15 from the side with one finger, and open the tag tape 15. . In particular, in the case of an individual napkin in which the center seal is not applied to the opening side edge portion 14a or a narrow individual napkin, it is easy to insert a finger from the side of the tag tape 15 so that the opening is easy.

  Further, since the non-adhesive knob portion 15a is formed on the side edge portion of the tag tape 15, even if the folding position is slightly changed or the mounting position is changed, the positional deviation is in the direction of the opening side edge 14a. Therefore, it is easy to stop the tag tape 15 not only in the product state but also when the used napkin 1 is wrapped in the packaging sheet 14 and discarded.

  By the way, various methods can be adopted as individual packaging forms of the napkin 1. For example, a six-fold configuration shown in FIGS.

Specifically, as shown in FIG. 12, the napkin 1 is disposed on the packaging sheet 16 . In the example of illustration, it arrange | positions in the state which made the outer edge of the one side wing-like flap W of the napkin 1 substantially correspond to the one side long side edge 17a.

It is a substantially rectangular sheet. In terms of material, paper or plastic film can be used, but it is preferably a thin and highly flexible plastic film. As shown in FIG. 12, the length is slightly longer than the total length of the napkin 1, and the extra length is secured on the front side and the rear side. The short dimension is the wing of the napkin 1. With respect to the width dimension in which the flat flaps W, W are developed, the extra length margin M of at least 5 mm width, preferably 10 mm width or more is secured as an adhesion region of the line-shaped adhesive 20 described later. Is desirable.

The contact surface on the napkin 1 side of the packaging sheet 16 is subjected to mold release treatment on the entire surface in the illustrated example, at least in an area corresponding to the range where the adhesive layer is formed. The release treatment can be formed by applying or spraying a release treatment liquid such as silicone resin, fluorine resin, or ethylene tetrafluoride resin. Further, a line-shaped adhesive 20 provided along the longitudinal direction is provided on the outer surface side of the packaging sheet 16 and in the vicinity of the other side longitudinal side edge. Further, on the short side edge 18a side, notches 19a and 19b are formed by cutting out the corners where the long side edges 17a and 17b intersect the short side edge 18a, respectively.

Here, the position of the fold line A is set to a position near the outside of the side edge of the absorbent body 4 in the illustrated example, but in some cases, it does not include the side flap of the napkin main body and is the base end of the wing-shaped flap W. Is also possible. Or you may make it fold including a part of absorber side edge.

  Next, as shown in FIG. 13, the other longitudinal side edge 17 b side portion of the packaging sheet 16 is folded along the folding line B to the surface sheet 3 side along with the wing-shaped flap W. The other side long side edge 17b side part is adhered in a peelable manner by a line adhesive 20 provided on the outer surface of the one side long side edge 17a side part folded first. As shown in FIG. 14, in a state in which both side portions of the longitudinal side edges 17 a and 17 b of the packaging sheet 16 are sequentially folded toward the liquid-permeable surface sheet 3, formed by the notches 19 a and 19 b formed in the packaging sheet 16. A part of the napkin 1 including the end portion (hatched area) of the absorbent body 4 is exposed to the outside from the opened opening. It is desirable that the exposure distance S from the end of the absorber is about 5 to 20 mm, preferably about 10 to 20 mm. The line adhesive 20 is fixed to the long side edge 17a on one side in the product state, but is provided on the surface on the mold release side of the long side edge 17b on the other side in the production line. It is desirable that the side edge 17b is superimposed on the one side long side edge 17a so as to be transferred to the one side long side edge 17a. The line adhesive 20 may be continuous or intermittent.

  When the folding of the napkin 1 and the packaging sheet 16 in the width direction is completed, as shown in FIG. 14, it is a direction along the short side edges 18 a and 18 b of the packaging sheet 16 and closer to the rear side of the napkin 1.
