Description

TECHNICAL FIELD The present invention relates to an absorbent article provided with a perfume bag.

Absorbent articles generally consist of a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent body disposed between the topsheet and the backsheet, thereby absorbing urine and the like. Body fluids are absorbed into the absorbent through the topsheet. These absorbent articles come in various types, such as tape-type disposable diapers, underpants-type disposable diapers, incontinence pads, and light incontinence pads, depending on their uses.

In order to alleviate bad odor during post-treatment of used absorbent articles, for example, there is a method of spraying the absorbent article with a deodorant spray. However, it is troublesome to use the spray itself in nursing care sites where there is a lot of work, and it may be necessary to disinfect the spray itself after using the spray with the hand that touched the used absorbent article. .

On the other hand, a method is known in which the absorbent article itself is scented with perfume. For example, Patent Document 1 discloses a water-soluble film containing perfume. Moreover, Patent Document 2 discloses a method of putting microcapsules containing a perfume that disintegrates upon wetting into an absorber. Furthermore, Patent Literature 3 discloses a method of mixing a fragrance into the adhesive layer of the post-treatment tape. Further, Patent Document 4 discloses a method in which an easy-to-open perfume bag attached to an individual package is opened at the same time when the wearer opens the individual package at the start of use.

Absorbent articles carrying fragrances are required to have a structure in which the fragrances do not volatilize or the effects of the fragrances do not disappear from the time the absorbent articles are made to carry the fragrances during the manufacturing process until they are actually used.
However, although the techniques of Patent Documents 1 and 2 are effective for watery urine, there is a problem that they are not effective for watery stool. In addition, in the technique of Patent Document 3, the fragrance generally permeates the adhesive and tends to reduce the adhesive strength, so when the product is stored for a long time, there is a possibility that the function as a post-treatment tape will be reduced. be.
Other methods such as using pressure-sensitive capsules are also conceivable, but since the product itself is soft in order to increase the cushioning properties of the absorbent article, the capsules are less likely to break, and the odor is sufficiently alleviated. There is a problem that a considerable amount of capsules is required to carry an amount of perfume on the absorbent article. In addition, Patent Document 4 is epoch-making in that taking out the absorbent article triggers volatilization of the fragrance, but the fragrance is released only when the absorbent article is replaced, and the volatilization of the fragrance is confined in the bag. The fragrance is released into the atmosphere through only one opening, and the fragrance is difficult to emit.
The present invention has been made in view of the above circumstances, and provides an absorbent article that has a deodorant function during use and can alleviate bad odors in a trash can during disposal of used absorbent articles and after disposal. It is intended to provide

As a result of intensive research, the present inventors have found that a perfume bag, in which a perfume sheet is enclosed in a film bag and has a plurality of openings, is attached to an absorbent article so as to be unsealable, and a lid material of the perfume bag By providing an adhesive layer on the surface and using it as a post-treatment tape so that the absorbent article after use can be rolled up and discarded, it has a deodorizing function during use and a function during processing and after disposal of the used absorbent article. The present inventors have found that it is possible to alleviate the bad odor in the trash can, and have completed the present invention.

That is, the present invention provides an absorbent article comprising an absorbent article main body and a perfume bag provided on the back sheet of the absorbent article main body and enclosing a perfume sheet impregnated with a perfume, wherein the perfume bag is The main body of the bag is made by heat-sealing the four sides of two overlapping substantially rectangular films. The absorbent article is detachably adhered to the bag body via an adhesive layer, and a knob portion is provided at one end in the width direction of the absorbent article of the lid material. is provided with a plurality of closed-loop-shaped opening guide lines whose center points are arranged at regular intervals in the width direction of the absorbent article.

A part of each figure formed by each closed loop of the opening guide line may be similar to each other.

The figures formed by the respective closed loops of the opening guide lines may be similar in shape, and the area of each of the figures may decrease in order toward the knob portion side.

The figures formed by the respective closed loops of the opening guide lines may be similar in shape, and the area of each of the figures may increase in order toward the knob portion side.

A surface of the lid material opposite to the surface on which the adhesive layer is provided may be provided with a display portion indicating the position of each opening-planned portion.

There may be.

<Absorbent article>
One embodiment of the absorbent article 10 of the present invention will be described.
As shown in FIGS. 1 and 2, an absorbent article 10 according to one embodiment of the present invention includes an absorbent article body 11 and a perfume sheet 22 provided on a back sheet 12 of the absorbent article body 11 and impregnated with a perfume. and a perfume bag 20 containing Specifically, the perfume bag 20 is provided on the non-skin contact side of the back sheet 12 .

In this embodiment, as shown in FIG. 1, the perfume bag 20 is positioned on the abdomen side of the absorbent article body 11 when worn (the right end of the paper indicates the abdomen end of the absorbent article body 11). ). When the perfume bag 20 is attached on the back side, a slight step may cause discomfort, and especially for elderly people, a slight step may cause bedsores. However, since the perfume bag 20 is attached to the abdominal side of the absorbent article 10 as in the present embodiment, such discomfort does not occur. Furthermore, since the perfume bag 20 is attached to the abdomen, both the caregiver and the wearer can easily operate the perfume bag 20 when, for example, they want to adjust the strength of the scent during wearing.
The configuration of the perfume bag 20 will be described below.

<perfume bag>
2 is a plan view showing the perfume bag 20, and FIG. 3 is a cross-sectional view taken along line XX' in FIG. As shown in FIGS. 2 and 3, the bag main body 21 of the perfume bag 20 containing the perfume sheet 22 impregnated with perfume is formed by heat-sealing two overlapping substantially rectangular films (bag main body films 21a and 21b) on four sides. Then, a heat-sealed portion 23 is formed to form a bag.
The bag body 21 is composed of two substantially rectangular bag body films 21a and 21b as described above. As for the size of the bag body 21, the dimension in the longitudinal direction (X-axis direction) of the absorbent article 10 is preferably 40 mm or more and 70 mm or less, and the dimension in the width direction (Y-axis direction) is preferably 100 mm or more and 150 mm or less. Preferably. The width of the heat-sealed portion 23 depends on the material of the two bag body films 21a and 21b, but is 3 mm or more and 15 mm or less from the viewpoint of preventing the fragrance bag 20 from being opened by an unintended force. is preferred.

(the film)
The bag body films 21a and 21b are composed of a barrier layer having a high fragrance retaining property in order to retain the fragrance until the fragrance bag 20 is opened, and the bag body film 21a and the bag body to form the bag body 21. It is preferable that at least two layers of materials including a sealant layer for welding the film 21b are laminated. Either dry lamination or extrusion lamination may be used for laminating each layer, and the optimum means can be selected according to the materials to be combined.

As the barrier layer, films such as polyethylene terephthalate (PET), polycarbonate (PC), polyacrylonitrile (PAN), and ethylene vinyl alcohol copolymer (EVOH), which are generally known as resins with high aroma retention properties, can be used. By coating or vapor-depositing the film surface, it is possible to use a film whose aroma retention is further improved. Such films include polyvinylidene chloride-coated oriented polypropylene (KOP), polyvinylidene chloride-coated oriented nylon (KONy), polyvinylidene chloride-coated polyethylene terephthalate (KPET), polyvinyl alcohol-coated oriented polypropylene (AOP), aluminum, alumina or Silica-deposited polyethylene terephthalate (PET), oriented nylon (ONy), oriented polypropylene (OPP), and the like can be used.

In addition, since many of those with high oxygen barrier properties also have high aroma retention properties, a film with high oxygen barrier properties can be mentioned as a guideline for selecting a barrier layer. However, the permeability of the film to gases such as fragrances and oxygen is determined by the solubility of the gas in the film resin and the diffusivity in the resin (amount of crystals). does not necessarily correlate with Therefore, it is preferable to select a film to be used as a barrier layer while actually confirming the permeability of each fragrance, not based only on oxygen barrier properties.

As the sealant layer, a resin that is usually used as a sealant layer is used. ) is desirable, but when emphasizing ease of sealing, linear low-density polyethylene (LLDPE), ethylene acrylic acid copolymer (EAA), ethylene vinyl acetate copolymer (EVA), ionomer (IO), etc. are preferable. .

In addition, by laminating aluminum foil in addition to the film, the aroma retaining property can be further enhanced.
Preferred film configurations that can be used in the present invention include EVOH/ONy/LLDPE, aluminum-deposited PET/ONyLDPE/LLDPE, silica-deposited PET/LDPE/LLDPE, alumina-deposited ONy/LLDPE, KONy/LLDPE, PET/aluminum foil/ CPP etc. are mentioned. The film thickness of each layer is preferably 10 μm or more and 15 μm or less for the barrier layer and 40 μm or more and 60 μm or less for the sealant layer.

(Scheduled opening, opening guidance line and opening)
Of the bag body films 21a and 21b in the bag body 21, the bag body film 21a on the non-skin-contacting side has a plurality of closed-loop-shaped loops whose center points are evenly spaced in the width direction of the absorbent article 10. An opening guide wire 25 is provided. At this time, the opening guiding wire 25 is preferably formed by perforating the bag main body film 21a along the outer periphery of the intended opening portion 24 or cutting (half-cutting) about half in the thickness direction of the film, which will be described later. Any other method may be used as long as the film in the portion to be opened 24 can be pulled out together with the adhesive layer 28 when the lid member 26 is peeled off.
Further, the number of opening scheduled portions 24 is not particularly limited as long as two or more are provided, but it is preferable that four opening scheduled portions 24a to 24d shown in FIGS. 2 and 3 are provided.

Furthermore, an adhesive layer 28 is provided on the side of the skin contacting surface of the lid material 26 that covers the planned opening portion 24, and the lid material 26 can be separated from the bag body 21 (bag body film 21a) via the adhesive layer 28. Glued. In the method of use described later, when the lid material 26 is peeled off from the bag body 21, the film of the intended opening portion 24 is removed together with the lid material 26 while being adhered to the adhesive layer 28 (the opening portion film 35 shown in FIG. 5). ), the removed portions become the openings 34 (openings 34a to 34d) as they are.

At this time, since the center points (C1 to C4 shown in FIG. 2) of the opening planned portion 24 (the closed loop formed by the opening guide wire 25) are equidistant as described above, the adhesive layer 28 of the removed lid member 26 The opening film 35 attached to the opening can close the opening 34 that is not desired to be opened (in FIGS. 4 and 5, the openings 34a and 34b are open, and the openings 34c and 34d are covered by the lid material). 26). That is, the opening number can be controlled by shifting the position of the lid member 26 toward the knob portion 27 side of the lid member 26 .
In the absorbent article 10 of the present embodiment, the number of open openings 34 can be adjusted by once peeling off the lid member 26 as shown in FIG. Therefore, for example, when excretion occurs while wearing the absorbent article 10, the absorbent article 10 is worn with the perfume bag 20 in the state shown in FIG. By using the absorbent article 10 in this way, the deodorant function during use can be maintained.
Another effect of dividing the opening 34 into a plurality of parts is that even if the area of each opening 34 is widened in order to increase the volatilization of the perfume, the perfume sheet 22 impregnated with the perfume does not move from the bag body 21. It is also mentioned that it does not fall off.

In addition, it is preferable that part or all of the figures (opening planned parts 24) formed by the respective closed loops of the opening guide wire 25 are similar to each other. It is preferred that they are progressively smaller towards one side. If the closed opening 34 is closed only with the adhesive layer 28, the perfume may move to the adhesive layer 28 and reduce the adhesive ability. Therefore, the opening 34 closed when the lid member 26 is shifted is desirably covered with the opening film 35 pulled out from the opened opening 34 (opening planned portion 24). are of the same area, it is difficult to reapply the lid 26 to fit snugly. Therefore, if the opening 34 has a similar shape and the area decreases in the direction in which the lid member 26 is shifted (the side where the knob portion 27 is located), the alignment of the lid member 26 is facilitated.
Also, although not shown, assuming that the user shifts the lid member 26 in the direction opposite to the side where the knob 27 is located, the openings 34 are similar in shape to each other, and , the area may increase in order toward the side where the knob 27 is located, which also facilitates positioning of the lid member 26. - 特許庁

(perfume sheet)
The perfume sheet 22 is preferably a sheet-like base material impregnated with a perfume.
The sheet-like substrate is preferably filter paper, which is easily impregnated with perfume, but spunbond nonwoven fabric obtained by hydroentangling pulp with nonwoven fabric is also preferred because of its absorbency and flexibility.

(perfume)
As the perfume with which the perfume sheet 22 is impregnated, either a natural perfume or a synthetic perfume may be used. Among them, it is preferable to use one having a masking effect, particularly a harmonizing effect, on the odor of excrement.
Specific examples of fragrances include natural fragrances such as aryang incense, benzoin incense, castor incense, spirit incense, clove oil, galbanum, jasmine absolute, melilot, mimosa, musk tonquin, rosemary oil, sandalwood oil, vetiver oil, violet leaf absolute. Fragrance extracts, higher alcohols, aldehydes, benzaldehyde, benzoic acid, cinnamic acid, cinnamic aldehydes, cinnamic alcohols, esters, ketones, salicylic acid and related compounds, various synthetic fragrances such as vanillin, or mixtures of two or more of these Commercially available products can be widely used as fragrances.

It is preferable that the perfume sheet 22 is impregnated with 10 mg or more and 50 mg or less of the perfume.

(lid material)
As shown in FIG. 3, of the films constituting the bag body 21, the non-skin-contacting surface of the bag-body film 21a on the non-skin-contacting side is provided with a cover material 26 via an adhesive layer 28, which is attached to the bag body. 21 is detachably adhered. A knob portion 27 is provided at one end portion of the lid member 26 in the width direction of the absorbent article 10 .
The lid member 26 is a film provided on one side with an adhesive layer 28 containing acrylic, ethylene-vinyl acetate copolymer, vinyl chloride monomer kraft polymer, or the like. There is no stickiness, or the stickiness is reduced by applying powder. Note that oriented polypropylene (OPP) or the like can be used as the film.

In addition, the length of the bag body 21 should be at least twice as long as the length of the lid member 26 in the width direction so that the once peeled lid member 26 can be reattached to the bag body 21 as shown in FIG. is preferred. Also, the end portion of the lid member 26 opposite to the end portion where the knob portion 27 is provided, and the intended opening portion 24a located first in the width direction from the end portion of the lid member 26 opposite to the knob portion 27. The distance (L1) of is preferably 5 mm or more because the lid member 26 is used as a post-processing tape after use.

In addition, the distance (L2) between the first scheduled opening portion 24a in the width direction from the end of the lid member 26 opposite to the knob portion 27 and the next scheduled opening portion 24b is twice L1. It is desirable to be above. Since the distance is two times or more, even when the lid member 26 is shifted so as to open only one of the opened openings 34, for example, the opening portion 34a, the end portion of the lid member 26 is caught on the opening portion 34a. and does not block any part of it.

In addition, it is preferable to provide a display portion indicating the position of each opening portion 24 on the surface of the cover member 26 opposite to the surface on which the adhesive layer 28 is provided (not shown). As a result, even when the user shifts the lid member 26 and attaches it to another place, there is no need to check the position of the opening film 35 from the side of the adhesive layer 28 each time, and the adhesive layer 28 is provided. It can be visually recognized from the surface opposite to the surface, and the positioning of the lid member 26 is facilitated. The display section is not particularly limited as long as it is a known method such as printing. For example, a display portion having the same shape as the aperture film 35 may be formed by printing.

<Absorbent article body>

Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, composite films of polyethylene and polypropylene, and the like.

(Absorber)
A well-known thing can be used as an absorber. Examples include those containing fluff pulp and superabsorbent polymers.

Examples of fluff pulp include wood pulp (for example, bleached softwood kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fiber, resin fiber, non-wood pulp, etc., which are defibrated into cotton. can.

The superabsorbent polymer is not particularly limited as long as it can absorb body fluids and prevent backflow. Sodium polyacrylate, polyaspartate, (starch-acrylic acid) graft copolymer, Those formed from materials such as (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers and saponified products thereof can be used. Among these, the sodium polyacrylate type is preferable from the viewpoint of the absorption amount per weight.

The form of the fluff pulp and the superabsorbent polymer in the absorbent body may be one formed by mixing superabsorbent polymer particles in the fluff pulp, and a superabsorbent polymer in which the superabsorbent polymer particles are fixed between the fluff pulp. It can be a sheet. For the purpose of preventing leakage of the superabsorbent polymer particles and stabilizing the shape of the absorbent body, the absorbent body may be wrapped in a carrier sheet. The base material of the carrier sheet may be any material as long as it is hydrophilic, and examples thereof include hydrophilic nonwoven fabrics such as tissues, absorbent paper, and air-laid nonwoven fabrics.
