Description

  The present invention relates to 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, or an incontinence pad, as shown in FIG. 31, for example, a liquid-impermeable back sheet 50 made of a polyethylene sheet or a polyethylene laminated nonwoven fabric or the like. And a liquid-permeable surface sheet 51 made of nonwoven fabric or a permeable plastic sheet, and the like. What formed the shape flaps W and W integrally is known.

  As this type of absorbent article N, in order to prevent misalignment in the mounted state, for example, one or more main body misalignments are formed on the non-skin contact surface side of the main body portion (the outer surface of the liquid-impermeable back sheet 50). There is one in which the stop adhesive layers 53, 53 are formed, and the wing-slap adhesive layers 54, 54 are formed on the surface (outer surface) of the wing-shaped flaps W, W on the liquid-impermeable back sheet 50 side.

  When the absorbent article N is fixed to the underwear, as shown in FIG. 32, the absorbent article N is locally applied and the wing-shaped flaps W, W protruding laterally are taken out from the underwear, and both wings are The 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 while the crotch portion of the underwear is wound.

  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. A method in which 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 Is common.

  In using such individual absorbent articles, the tag tape 60 is removed, the folding in the longitudinal direction is released, the absorbent article N is taken out in an unfolded state, the release sheet is peeled off, and the underwear is attached. When disposing of the used absorbent article, the used absorbent article is rolled up in the longitudinal direction, and then wrapped with the packaging sheet 61 from which the new absorbent article N is taken out, and its end is fastened with a tag tape. In many cases, it is disposed of in a state of being wrapped in tissue or with multiple layers of tissue.

  As such individual absorbent articles, various products have been developed that have improved operability at the time of removal, disposal of used absorbent articles, and the like. For example, in Patent Document 1 below, the packaging bag does not need to be discarded, and the sanitary napkin can be easily taken out. It is provided along one side edge in the longitudinal direction of the napkin, and is fixed to the inner surface of the packaging bag only in the vicinity of one end edge in the longitudinal direction of the release paper, so that it is not peeled off from the adhesive layer when the sanitary napkin is taken out. A sanitary napkin packaging structure is disclosed.

  Further, in the following Patent Document 2, in order to be able to easily wrap a used napkin without fear of bleeding such as menstrual blood, a bag-like portion is provided on at least a part of the packaging film and absorbed. An individual package of an absorbent article is disclosed in which an absorbent article is placed on a packaging film via a release layer, folded in this laminated state, and fastened with a mounting tape.

  However, when disposing of used absorbent articles, especially in the case of users of light incontinence pads, do not throw them into sanitary boxes equipped with used absorbent articles so that others do not know that they have mild incontinence symptoms. Many people take it home. For this reason, not only the good disposability of used absorbent articles but also good portability has been demanded.

  Here, the light incontinence pad has a characteristic that the expansion rate of the pad after use is larger than that before use because it absorbs more body fluid than the sanitary napkin. doing. For this reason, even after the used light incontinence pad is rolled up and wrapped with a packaging sheet, even if the end is fastened with a tag tape, the tape is easily removed during transportation, and the rounded pad is difficult to hold and spread. There was a problem that. In addition, when a used absorbent article is wrapped with a tissue or the like, there is a problem that the tissue or the like is wasted and waste is increased.

  On the other hand, in the case of the packaging structure described in Patent Document 1, the unsealing part is provided along one side edge in the longitudinal direction of the sanitary napkin, and the release paper is provided via a fixing part provided in the direction perpendicular to the one side edge. Because it is fixed to the inner surface of the packaging bag, when taking out the sanitary napkin from the take-out port, it will be pulled out sideways with respect to the longitudinal direction of the release paper, and the release paper will peel off from the adhesive layer of the sanitary napkin In addition to being difficult to remove, a shearing force that tears the release paper or packaging bag is easily applied at the time of peeling, so that the release paper or packaging bag is easily torn and there is an inconvenience in terms of takeout.

  Further, in the individual package described in Patent Document 2, a part of the packaging film is doubled to form a bag-shaped portion, and the packaging film on which the bag-shaped portion is formed is like a single film. Since the packaging film and the sanitary napkin are both folded in the same manner as in the prior art, additional materials for forming the bag-like portion are required, which increases the cost.

  Therefore, the main problem of the present invention is to provide an individual absorbent article that is excellent in operability when taking out the absorbent article and the disposal property of the used absorbent article, reduces the material cost, and requires less waste. There is.

In order to solve the above-mentioned problem, as the present invention according to claim 1, a main body slip-preventing pressure-sensitive adhesive layer is formed on a surface of the main body portion where an absorbent body is interposed between a liquid-permeable front sheet and a back sheet. Formed of an absorbent article, a release material for the main body that covers the adhesive layer for preventing misalignment of the main body, and a packaging sheet for individually packaging the absorbent article, the absorbent article, the release material for the main body, and the packaging sheet Are each disposed along the longitudinal direction, and are individually packaged absorbent articles that are folded in the longitudinal direction into a individually packaged state,
In the individually packaged state, a fixing portion is formed in which one end in the longitudinal direction of the release material for the main body is fixed to the inner surface near the one end in the longitudinal direction of the packaging sheet, and the other end in the longitudinal direction of the fixing portion The longitudinal direction other end side portion of the packaging sheet is folded together with the absorbent article and the release material for the main body, and the packaging sheets are fixed to each other at the side edge seal portions in the folded portion in the longitudinal direction. A bag-like portion having an opening toward one end side is formed, and the longitudinal direction one end side portion of the packaging sheet is folded so as to seal the opening, and is fastened to the outer surface of the packaging sheet ,
The region where the release material for the main body and the packaging sheet overlap, and the portion near the other end in the longitudinal direction of the packaging sheet is dragged to the absorbent article when the absorbent article is taken out at the time of opening with respect to the release material for the main body. The temporary fixing part temporarily fixed with the adhesive force to the extent that the fastening state is released by the tensile force generated when the release material for the main body is pulled out from the bag-like part of the packaging sheet is formed. A featured absorbent article is provided.

  In the first aspect of the present invention, the absorbent article, the release material for the main body, and the packaging sheet are arranged along the longitudinal direction, and are folded in the longitudinal direction to be individually packaged. When a tensile force in the longitudinal direction acts on the absorbent article when the article is taken out, a longitudinal force is also applied to the release material for the main body and the packaging sheet, respectively, and the release material and the packaging sheet are torn or torn. Can be prevented, and the operability when taking out can be improved. In addition, one end in the longitudinal direction of the release material for the main body is fixed to the inner surface of the packaging sheet, and the other end side in the longitudinal direction of the packaging sheet that is the other end in the longitudinal direction of the fixing portion is the absorbent article and Folded together with the release material for the main body, and in the folded portion, the packaging sheets are fixed to each other at the side edge seal portions on both sides, thereby forming a bag-like portion having an opening toward one end in the longitudinal direction. Therefore, at the time of opening, if the absorbent article is pulled out from the bag-like portion of the packaging sheet and taken out, the release material for the main body remains on the packaging sheet side and is peeled off from the main body slip-off adhesive layer of the absorbent article. Therefore, it can be immediately attached to the underwear in the taken out state, and the operability when taking out the absorbent article is excellent, and the workability of attaching the absorbent article is improved.

  Furthermore, at the time of disposal of the used absorbent article, after the used absorbent article is rounded in the longitudinal direction, it is inserted into the bag-like part while further wrapping the outer surface with a release material for the main body, Or, after inserting the rolled used absorbent article as it is into the bag-like part, the used absorbent article is difficult to spread in the bag-like part by inserting the bag so as to cover the release material for the main body. Therefore, the used absorbent article can be held in the bag-like portion. For this reason, it becomes excellent in the discardability and carrying property of a used absorbent article. In addition, since the used absorbent article can be completely wrapped by storing it in the bag-like portion of the packaging sheet, it is not necessary to wrap it with a tissue or the like, and waste can be reduced.

  In addition, when forming the bag-like portion by folding the other end portion in the longitudinal direction of the packaging sheet, the packaging sheet is folded together with the absorbent article and the release material for the main body. The material required for the packaging sheet can be reduced as compared with the case where the absorbent article is placed and folded after being folded in advance to form a double sheet, and the material can be saved.

Further, the main body release material has one end in the longitudinal direction of the main body release material fixed to the inner surface of the packaging sheet by the fixing portion, but the other end in the longitudinal direction is merely placed on the packaging sheet. or flapping, because or shift during transport, the a region where the body release material and the package sheet are overlapped, with respect to the other longitudinal end side portion of the body release material of the package sheet, upon opening When the absorbent article is taken out, it is temporarily fixed with an adhesive force that is pulled by the absorbent article and is released by the tensile force generated when the release material for the main body is pulled out from the bag-like portion of the packaging sheet. A temporary fixing portion is formed .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Basic configuration of light incontinence pad 1]
As shown in FIGS. 1 and 2, the light incontinence pad 1 according to the present invention is provided between a liquid-impermeable back sheet 2 and a liquid-permeable surface sheet 3 (hereinafter also simply referred to as a surface sheet). As shown in the figure, the absorbent body 4 or the absorbent body 4 surrounded by the crepe paper 5 is interposed, and the side nonwoven fabrics 7 and 7 are provided on both sides of the surface side.

  The liquid-impervious back sheet 2 is made of a sheet material having at least water-impervious properties such as polyethylene and polypropylene, but in addition to this, a non-woven sheet after securing a substantially liquid-impervious property through a waterproof film. (In this case, a liquid-impervious back sheet is composed of the waterproof film and the nonwoven fabric). In recent years, those having moisture permeability tend to be suitably 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. A sheet is preferably used.

  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.

  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.

  The absorbent body 4 may be mixed with synthetic fibers. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.

  Examples of the superabsorbent resin include cross-linked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer cross-linked, isobutylene / maleic anhydride copolymer cross-linked, Examples include cross-linked polysulfonates, and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Among these, those based on acrylic acid or acrylate that are excellent in water absorption and water absorption speed are preferred. In the production process of the highly water-absorbent resin having the water absorption performance, the water absorption force and the water absorption speed can be adjusted by adjusting the crosslinking density and the crosslinking density gradient. The content of the highly water-absorbent resin is desirably 10 to 60% of the weight of the absorber. When the content of the superabsorbent resin is less than 10%, sufficient absorbability cannot be provided, and when it exceeds 60%, the entanglement between the pulp fibers disappears, the sheet strength decreases, and tears, cracks, etc. Is likely to occur.

  Side nonwoven fabrics 7 and 7 are provided on the both sides of the light incontinence pad 1 along the longitudinal direction and over the entire length of the light incontinence pad 1, and outside the side nonwoven fabrics 7 and 7. While the part is extended to the side, the liquid-impervious back sheet 2 is extended to the side, and the side nonwoven fabric 7 part and the liquid-impervious back sheet 2 part that are extended to the side. Side flaps are formed by bonding with a hot melt adhesive or the like.

  As the side nonwoven fabric 7, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used from the viewpoint of an important function. For example, if importance is placed on functions such as preventing the infiltration of urine and cages, or enhancing the feeling of touch, a water-repellent non-woven fabric coated with a silicon-based, paraffin-based, or alkylchromic chloride-based water repellent. If the emphasis is on the absorbability of body fluids, 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, or stannic chloride Hydrophilic treated non-woven fabric that has been treated with a metal salt, made partially porous by dissolving the surface, making the synthetic fiber swelled or made porous by applying metal hydroxide, etc., and applying hydrophilicity by applying capillary action It is desirable to use The side nonwoven fabric 7 can be made of natural fiber, synthetic fiber, regenerated fiber, or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 7 is made air-permeable with a reduced basis weight. Nonwoven fabric should be used.

  As shown in FIG. 2, the inner side of the side nonwoven fabric 7 folds the side nonwoven fabric 7 almost double, and inside the double sheet, in the middle in the height direction, as appropriate at both ends or in the longitudinal direction. One or a plurality of, in the illustrated example, two thread-like elastic elastic members 8 and 8 are disposed, and the double sheet portion is raised on the surface side by the contraction force. Is formed.

  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 liquid-impervious back sheet 2 (the liquid-impervious back sheet 2 Are formed on the outer surface of the main body by a suitable application pattern for fixing to the underwear, and in the illustrated example, three main body misalignment adhesive layers 9, 9... Are formed. Layers 9, 9... Are releasably covered with a release material 10 for main body.

  As the pressure-sensitive adhesive forming the main body displacement-preventing pressure-sensitive adhesive layer 9, for example, a styrene polymer, a tackifier, or a plasticizer that is a 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 material 10 for the main body, for example, a release treatment liquid such as a silicone resin, a fluorine resin, or a tetrafluoroethylene resin is applied to the contact surface with the main body displacement prevention adhesive layer 9. Paper or plastic sheet that has been spray-coated and mold-released 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.

  The light incontinence pad 1 is individually packaged, and the main body displacement preventing adhesive layers 9, 9... Are covered with the main body release material 10, and a packaging sheet 11 is further disposed on the outer surface thereof. The main body release material 10 and the packaging sheet 11 are arranged along the longitudinal direction, and are folded and packaged in the longitudinal direction by a predetermined folding procedure.

  As shown in FIG. 1, the packaging sheet 11 for individually mounting the light incontinence pad 1 corresponds to a pair of left and right long side edges corresponding to the longitudinal direction of the pad 1, and a short direction (width direction) of the pad 1. The rectangular sheet is defined by a pair of short side edges. As a material, a nonwoven fabric, paper, a plastic film, or the like can be used, but preferably a nonwoven fabric having high flexibility and good touch. In terms of dimensions, as shown in FIG. 1, the short dimension is a dimension that extends to both sides wider than the main body portion of the light incontinence pad 1. Further, as a longitudinal dimension, at least one end side (the side on which the tag tape 12 is provided, the side corresponding to the front side of the light incontinence pad 1) is formed to extend forward from the front end of the light incontinence pad 1, and the other end The side (the side corresponding to the rear side of the light incontinence pad 1) may be formed to extend rearward from the rear end of the light incontinence pad 1 according to individual packaging (FIG. 1 and the like), or after the light incontinence pad 1 It is formed shorter than the end (FIG. 16 etc.). Details will be described in the section for individual packaging in the latter part.

  As shown in FIG. 1, the packaging sheet 11 and the main body release material 10 are fixed so as not to be peeled off by a fixing portion 13 provided at a predetermined position. Here, “unpeelable” means that the fixed state of the packaging sheet 11 and the main body release material 10 is not released by the tensile force when the light incontinence pad 1 is taken out when the individual light incontinence pad is opened.

  The main body release material 10 and the packaging sheet 11 have one end in the longitudinal direction of the main body release material 10 (the end on the side corresponding to the front side of the light incontinence pad 1) and one end in the longitudinal direction of the packaging sheet 11 (tag). It is fixed to the inner surface near the tape 12 side, the end corresponding to the front side of the light incontinence pad 1) by a fixing portion 13 fixed in a non-peelable manner by heat seal or adhesive. By providing such a fixing portion 13, simply removing the light incontinence pad 1 at the time of opening, the release material 10 for the main body is peeled from the light incontinence pad 1. Since the release material remains on the side of the packaging sheet 11, the trouble of discarding the release material can be omitted.

  The fixing portion 13 is preferably located on the front side of the pad with respect to the main body displacement prevention adhesive layer 9, and as shown in FIG. 3, the separation distance D1 from the front end of the main body displacement prevention adhesive layer 9 is 5 mm to It is preferable to provide at a position of 10 mm. Thereby, when taking out the light incontinence pad 1 at the time of opening, peeling from the light incontinence pad 1 of the main body release material 10 starts from the front end side of the main body displacement prevention adhesive layer 9 and gradually proceeds from the front side toward the rear side. Since peeling moves, the pulling force when the light incontinence pad 1 is taken out can be small, and the taking out operability is excellent.
