Description

[Technical field]

[0001] The present invention relates to an absorbent article with a perfume pouch. [Background technology]

[0002] Generally, absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between the top sheet and the back sheet, so that body fluids such as urine are absorbed into the absorbent body through the top sheet. There are various types of absorbent articles according to their applications, such as tape-type disposable diapers, pants-type disposable diapers, urine pads, and light incontinence pads.

[0003] In order to reduce the bad odors that may occur during the post-treatment of used absorbent articles, for example, there is a method of spraying a deodorant spray onto the absorbent articles. However, in a nursing care site with a large amount of work, using the spray itself is troublesome, and there are cases where the spray itself needs to be disinfected after using the spray with hands that have touched used absorbent articles.

[0004] Meanwhile, methods of imparting fragrance to the absorbent article itself are known. For example, Patent Document 1 discloses a water-soluble film containing fragrance. Patent Document 2 discloses a method of placing a fragrance in microcapsules that disintegrate when moistened, and then placing the microcapsules in an absorbent. Patent Document 3 discloses a method of mixing a fragrance into the adhesive layer of a post-treatment tape. Patent Document 4 discloses a method in which an easily openable fragrance bag attached to an individual package is opened by the wearer at the start of use at the same time as the wearer opens the individual package. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 63-100021 [Patent Document 2] Japanese Patent Application Publication No. 59-106501 [Patent Document 3] JP 2016-067912 A [Patent Document 4] JP 2014-223129 A Summary of the Invention [Problem to be solved by the invention]

[0006] Absorbent articles carrying fragrances are required to have a structure in which the fragrance does not volatilize or the effects of the fragrance do not disappear from the time the fragrance is loaded into the absorbent article during manufacture until the article is actually used. However, the techniques of Patent Documents 1 and 2 have the problem that, although they are effective for urine, which has a lot of water, they are not effective for feces, which has little water. Also, in the technique of Patent Document 3, since fragrances generally tend to permeate the adhesive and reduce the adhesive strength, there is a possibility that the function of the post-treatment tape will decrease if the product is stored for a long period of time. Other methods such as using pressure-sensitive capsules are also possible, but since absorbent articles are soft in order to increase their cushioning properties, the capsules are difficult to break, and there is a problem that a considerable number of capsules are required to support the amount of fragrance in the absorbent article to sufficiently alleviate the bad odor. Furthermore, although Patent Document 4 is groundbreaking in that removing the absorbent article triggers the fragrance to volatilize, the fragrance only becomes fragrant when the absorbent article is replaced, and the fragrance volatilizes because the fragrance trapped in the bag is released into the air through only one opening, making it difficult for the fragrance to become fragrant. The present invention has been made in consideration of the above circumstances, and aims to provide an absorbent article that has a deodorizing function during use and can reduce bad odors when disposing of a used absorbent article and in a trash can after disposal. [Means for solving the problem]

[0007] As a result of extensive research, the inventors have discovered that by attaching a fragrance sheet contained within a film bag and opening the fragrance bag in an openable manner to an absorbent article, and further providing an adhesive layer on the lid of the fragrance bag to be used as a post-disposal tape so that the absorbent article can be rolled up and disposed of after use, it is possible to achieve a deodorizing function during use and to reduce bad odors when disposing of the used absorbent article and in the trash can after disposal, thereby arriving at the present invention.

[0008] In other words, the present invention is an absorbent article having an absorbent article main body and a fragrance bag provided on the back sheet of the absorbent article main body and containing a fragrance sheet impregnated with a fragrance, wherein the bag body of the fragrance bag is made by heat-sealing the four sides of two overlapping, approximately rectangular films, a lid material is releasably adhered to the bag body via an adhesive layer on the non-skin-contacting surface of the film on the non-skin-contacting surface side of the film, a handle portion is provided at one end of the lid material in the width direction of the absorbent article, and the film on the non-skin-contacting surface side of the film is provided with a plurality of closed-loop opening guide lines whose center points are evenly spaced in the width direction of the absorbent article.

[0009] Each part of the figure formed by each closed loop of the opening guide line may be similar to each other.

[0010] The figures formed by the respective closed loops of the opening guide line may be similar to each other, and the areas of the figures may decrease in order from one side to the other toward the side where the gripping portion is located.

[0011] The figures formed by the respective closed loops of the opening guide line may be similar to each other, and the areas of the figures may increase in order from one side to the other toward the side where the gripping portion is located.

[0012] The surface of the lid material opposite to the surface on which the adhesive layer is provided may be provided with an indicator section which indicates the location of each intended opening section. Effect of the Invention

[0013] According to the present invention, it is possible to provide an absorbent article that has a deodorizing function during use and can reduce bad odors during disposal of the used absorbent article and in a trash bin after disposal. [Brief description of the drawings]

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are presented for illustrative purposes and are not intended to limit the present invention.

[0016] In the description of this specification, the time when the absorbent article 10 is worn refers to at least one of the time when the absorbent article 10 is worn and the time after the absorbent article 10 is worn. The longitudinal direction of the absorbent article 10 is the direction extending from the front to the back of the wearer when the absorbent article 10 is worn, and is the direction indicated by the symbol Y in the figure. The width direction of the absorbent article 10 is the direction horizontal to or perpendicular to the longitudinal direction, and is the direction indicated by the symbol X in the figure. Furthermore, the skin contact surface is the surface of each member such as the absorbent body that faces the skin side of the wearer when worn, and the non-skin contact surface is the surface of each member such as the absorbent body that faces the opposite side to the skin side of the wearer when worn. Body fluids refer to liquids discharged from the body to the outside, such as urine, blood, and water in loose stool. Furthermore, examples of the absorbent article 10 include light incontinence pads, pants-type paper diapers, and tape-fastened paper diapers, regardless of whether they are for babies or adults, but are not limited to these and may be other absorbent articles.

[0017] <Absorbent articles> An embodiment of the absorbent article 10 of the present invention will be described. 1 and 2, an absorbent article 10 according to one embodiment of the present invention includes an absorbent article main body 11 and a fragrance bag 20 that is provided on a back sheet 12 of the absorbent article main body 11 and contains a fragrance sheet 22 impregnated with a fragrance. Specifically, the fragrance bag 20 is provided on the non-skin contact surface side of the back sheet 12.

[0018] In this embodiment, as shown in FIG. 1, the fragrance bag 20 is attached to the absorbent article main body 11 at a position that will be on the ventral side when worn (the end on the right side of the page indicates the ventral end of the absorbent article main body 11). If the fragrance bag 20 is attached to the dorsal side, discomfort may occur due to a slight difference in height, and for elderly people in particular, a slight difference in height can cause bedsores. However, as in this embodiment, by attaching the fragrance bag 20 to the ventral side of the absorbent article 10, such discomfort does not occur. Furthermore, by attaching the fragrance bag 20 to the ventral side, it is easy for both the caregiver and the wearer to operate the fragrance bag 20, for example, when it is desired to adjust the strength of the fragrance while wearing the article. The configuration of the spice bag 20 will now be described.

[0019] <Fragrance bag> Fig. 2 is a plan view showing the spice bag 20, and Fig. 3 is a cross-sectional view taken along line X-X' in Fig. 2. As shown in Fig. 2 and Fig. 3, the bag body 21 of the spice bag 20 containing the spice sheet 22 impregnated with spice is produced by heat-sealing the four sides of two overlapping, approximately rectangular films (bag body films 21a and 21b) to form a heat-sealed portion 23. As described above, the bag body 21 is composed of two roughly rectangular bag body films 21a and 21b. The size of the bag body 21 is preferably 40 mm or more and 70 mm or less in the longitudinal direction (X-axis direction) of the absorbent article 10, and is preferably 100 mm or more and 150 mm or less in the width direction (Y-axis direction). The width of the heat-sealed portion 23 depends on the material of the two bag body films 21a and 21b, but is preferably 3 mm or more and 15 mm or less from the viewpoint of preventing the fragrance bag 20 from being opened by unintended force.

[0020] (film) The bag main body films 21a and 21b are preferably made of at least two layers of material laminated together, including a barrier layer with high aroma retention properties in order to retain the aroma until the fragrance bag 20 is opened, and a sealant layer for welding the bag main body films 21a and 21b together to form the bag main body 21. The layers may be laminated by either dry lamination or extrusion lamination, and the most suitable method can be selected depending on the materials to be combined.

[0021] For the barrier layer, films such as polyethylene terephthalate (PET), polycarbonate (PC), polyacrylonitrile (PAN), and ethylene vinyl alcohol copolymer (EVOH), which are generally known to have high aroma retention, can be used, as well as films whose surface has been coated or vapor-deposited to further enhance aroma retention. Examples of 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), polyethylene terephthalate (PET) vapor-deposited with aluminum, alumina, or silica, oriented nylon (ONy), and oriented polypropylene (OPP).

[0022] Furthermore, since many films with high oxygen barrier properties also have high aroma retention, a film with high oxygen barrier properties can be used as a guide for selecting a barrier layer. However, the permeability of a film for gases such as fragrances and oxygen is determined by the solubility of the gas in the film resin and the diffusibility (amount of crystalline parts) within the resin, so aroma retention does not necessarily correlate with oxygen barrier properties. Therefore, it is preferable to select a film to be used for the barrier layer by actually checking the permeability for each fragrance, rather than using oxygen barrier properties as the only criterion.

[0023] The sealant layer is made of resins that are usually used for sealant layers. When aroma retention is a consideration, polyethylene terephthalate (PET), high density polyethylene (HDPE) or polypropylene (CPP) is preferable, while when ease of sealing is important, linear low density polyethylene (LLDPE), ethylene acrylic acid copolymer (EAA), ethylene vinyl acetate copolymer (EVA) or ionomer (IO) is preferable.

[0024] Furthermore, laminating aluminum foil in addition to the film can further enhance the aroma retention. 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. The 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.

[0025] (Opening area, opening guide 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 contact side is provided with a plurality of closed-loop opening guide lines 25 whose center points are aligned at equal intervals in the width direction of the absorbent article 10. In this case, the opening guide lines 25 are preferably formed by perforating the bag body film 21a along the outer periphery of the intended opening portion 24 or by making a cut (half cut) about halfway in the film thickness direction, but any other means may be used as long as the film of the intended opening portion 24 can be removed together with the adhesive layer 28 when the lid material 26 is peeled off in the method of use described below. Further, the number of the intended opening portions 24 is not particularly limited as long as two or more are provided, but it is preferable that four intended opening portions 24a to 24d are provided as shown in Figs.

[0026] Furthermore, an adhesive layer 28 is provided on the skin contact surface side of the lid material 26 covering the intended opening portion 24, and the lid material 26 is releasably adhered to the bag body 21 (bag body film 21a) via the adhesive layer 28. In a method of use described below, 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 still adhering to the adhesive layer 28 (becoming the opening film 35 shown in FIG. 5), and the removed portion becomes the opening 34 (openings 34a to 34d) as it is.

[0027] At this time, since the center points (C1 to C4 shown in FIG. 2) of the intended opening portion 24 (closed loop formed by the opening guide line 25) are equally spaced as described above, the opening film 35 attached to the adhesive layer 28 of the removed lid material 26 can close the openings 34 that are not to be opened (in FIGS. 4 and 5, the openings 34a and 34b are opened, and the openings 34c and 34d are closed by the lid material 26). That is, by shifting the position of the lid material 26 toward the knob portion 27 of the lid material 26, it is possible to control the number of openings. In the method of using the absorbent article 10 of this embodiment, which will be described later, the number of open openings 34 can be adjusted by removing the lid material 26 once and then reattaching it as shown in Fig. 4. Therefore, for example, if excretion occurs while wearing the absorbent article 10 and it is desired to reduce odor to some extent, the absorbent article 10 is worn with the fragrance bag 20 in the state shown in Fig. 4. By using the absorbent article 10 in this manner, the deodorizing function can be maintained during use. Another advantage of dividing the opening 34 into multiple parts is that even if the area of ​​each opening 34 is made larger to increase the evaporation of the fragrance, the fragrance sheet 22 impregnated with the fragrance will not fall out of the bag body 21.

[0028] In addition, it is preferable that the figures (the intended opening portion 24) formed by the respective closed loops of the opening guide line 25 are partially or entirely similar to each other, and that the areas of the figures are successively smaller toward the side where the tab 27 is located. If the blocked opening 34 is blocked only with the adhesive layer 28, the fragrance may move to the adhesive layer 28, which may reduce the adhesive ability. Therefore, it is preferable that the blocked opening 34 when the lid material 26 is shifted is covered with the opening film 35 removed from the opened opening 34 (the intended opening portion 24), but when each of the openings 34 has the same area, it is difficult to reattach the lid material 26 so that they fit perfectly. Therefore, if the openings 34 are similar to each other and the areas are successively smaller toward the direction in which the lid material 26 is shifted (the side where the tab 27 is located), it becomes easier to align the lid material 26. Also, although not shown, assuming that the user will shift the lid material 26 in the direction opposite to the side where the knob portion 27 is located, each of the openings 34 may be similar in shape and have areas that increase sequentially toward the side where the knob portion 27 is located, which also makes it easier to align the lid material 26.

[0029] (Fragrance sheet) The perfume sheet 22 is preferably a sheet-like substrate impregnated with a perfume. The sheet-like substrate is preferably filter paper, which is easily impregnated with the fragrance, but spunbond nonwoven fabric, in which pulp is hydroentangled with nonwoven fabric, is also preferred because of its absorbency and flexibility.

[0030] (fragrance) Either natural or synthetic fragrances may be used as the fragrance to be impregnated into the fragrance sheet 22. Among them, it is preferable to use a fragrance that has a masking effect against the odor of excrement, particularly a harmonizing effect. Specific examples of fragrances include naturally extracted fragrances such as magus incense, benzoin, sea lion incense, spirit cat incense, clove oil, galbanum, jasmine absolute, melilot, mimosa, musk tonkin, rosemary oil, sandalwood oil, vetiver oil, and violet leaf absolute; various synthetic fragrances such as higher alcohols, aldehydes, benzaldehyde, benzoic acid, cinnamic acid, cinnamic aldehyde, cinnamic alcohol, esters, ketones, salicylic acid and related compounds, and vanillin; and mixtures of two or more of these fragrances, which are commercially available and can be used widely.

[0031] The fragrance sheet 22 is preferably impregnated with 10 mg or more and 50 mg or less of fragrance.

[0032] (lid material) 3, of the films constituting the bag body 21, the bag body film 21a on the non-skin contact side has a lid material 26 releasably adhered to the bag body 21 via an adhesive layer 28. In addition, a tab 27 is provided at one end of the lid material 26 in the width direction of the absorbent article 10. The lid material 26 is a film having an adhesive layer 28 on one side, the adhesive layer 28 being made of acrylic, ethylene-vinyl acetate copolymer, craft polymer of vinyl chloride monomer, or the like, and the adhesive layer 28 is not provided on the tab 27, or the adhesiveness is reduced by applying powder to the tab 27. The film may be made of oriented polypropylene (OPP), or the like.

[0033] 4, the length of bag body 21 is preferably at least twice as long as the widthwise length of lid material 26 so that lid material 26, once peeled off, can be reattached to bag body 21. The distance (L1) between the end of lid material 26 opposite the end where tab 27 is provided and intended opening portion 24a that is the first in the widthwise direction from the end of lid material 26 opposite tab 27 is preferably 5 mm or more so that lid material 26 is used as a post-cleaning tape after use.

[0034] Furthermore, it is desirable that the distance (L2) between the first to-be-opened portion 24a and the next to-be-opened portion 24b in the width direction from the end of the lid material 26 opposite the knob portion 27 is at least twice as long as L1. By having a distance of at least twice as long, even when the lid material 26 is shifted so that, for example, only one of the opened openings 34, 34a, is opened, the end of the lid material 26 does not overlap the opening 34a and partially block it.

[0035] In addition, it is preferable to provide an indicator showing the location of each intended opening portion 24 on the surface of the lid material 26 opposite to the surface on which the adhesive layer 28 is provided (not shown). This makes it possible to visually recognize the position of the opening film 35 from the surface opposite to the surface on which the adhesive layer 28 is provided, even when the user shifts the lid material 26 and attaches it to another location, without the need to check the position of the opening film 35 from the surface side on which the adhesive layer 28 is provided, and makes it easy to align the lid material 26. The indicator is not particularly limited as long as it is formed by a known method such as printing. For example, an indicator having the same shape as the opening film 35 may be formed by printing.

[0036] <Absorbent article body> As shown in FIG. 1, an absorbent article main body 11 has, from the non-skin contact side, a back sheet 12, an absorbent body (not shown), and a top sheet (not shown).

[0037] (Back seat) The back sheet 12 may be made of any known material, and is preferably made of a liquid-impermeable substrate that prevents body fluids held by the absorbent from wetting clothing, and is preferably made of a material such as a resin film or a composite sheet made by laminating a resin film and a nonwoven fabric. The nonwoven fabric used in the composite sheet is not particularly limited in its manufacturing method, and examples thereof include spunbond nonwoven fabric, meltblown nonwoven fabric, laminated composite nonwoven fabric such as spunbond / meltblown or spunbond / meltblown / spunbond, and composite materials thereof. Examples of the resin film include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0038] (Absorbent) The absorbent may be any known absorbent, for example, one containing fluff pulp and a highly absorbent polymer.

[0039] Examples of fluff pulp include wood pulp (for example, bleached coniferous kraft pulp (N-BKP) such as southern pine or Douglas fir), synthetic fiber, resin fiber, non-wood pulp, etc. that have been defibrated into a cotton-like state.

[0040] The superabsorbent polymer is not particularly limited as long as it can absorb body fluids and prevent backflow, and can be made of materials such as sodium polyacrylate, polyaspartate, (starch-acrylic acid) graft copolymer, (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer, and saponification products thereof. Among these, sodium polyacrylate is preferred from the viewpoint of absorption per weight.

[0041] The form of the fluff pulp and superabsorbent polymer in the absorbent may be formed by mixing superabsorbent polymer particles in fluff pulp, or may be a superabsorbent polymer sheet in which superabsorbent polymer particles are fixed between fluff pulp. In addition, the absorbent may be wrapped in a carrier sheet for the purpose of preventing leakage of the superabsorbent polymer particles and stabilizing the shape of the absorbent. The substrate of the carrier sheet may be any hydrophilic material, such as tissue, absorbent paper, and hydrophilic nonwoven fabrics such as airlaid nonwoven fabrics. When a plurality of carrier sheets are provided, the substrates of the plurality of carrier sheets may be the same or different.

[0042] (Top sheet) As the top sheet, a known one can be used. The top sheet is preferably formed of a nonwoven fabric having such liquid permeability that the body fluid moves to the absorbent. The body fluid flowing onto the top sheet diffuses into the absorbent and is quickly absorbed by the absorbent. The top sheet is preferably formed of a material such as a nonwoven fabric such as an air-through nonwoven fabric, a thermal bond nonwoven fabric, a spunbond nonwoven fabric, a two-layer laminated composite nonwoven fabric of thermal bond / spunbond, a foamed film such as urethane foam, or a composite sheet laminated with these. In addition, the top sheet may be embossed or perforated on the surface in order to improve the liquid permeability. As a method for carrying out these embossing and perforation processes, known methods can be carried out without any restrictions. In addition, in order to reduce irritation to the skin, the top sheet may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc.

[0043] <How to use> The absorbent article 10 of the present invention is used as follows. When the absorbent article 10 is first used, the lid material 26 is peeled off, and a part of the bag body film 21a is peeled off from the intended opening portion 24 together with the adhesive layer 28 (as the opening film 35 shown in FIG. 5) along the opening guide line 25, forming an opening 34. Then, as shown in FIGS. 4 and 5, the lid material 26 is shifted from its original position and attached, so that both the opened openings 34 (openings 34a and 34b in FIGS. 4 and 5) and the closed openings 34 (openings 34c and 34d in FIGS. 4 and 5) are formed among the multiple openings 34, and the number of them can be adjusted. In this way, by controlling the number of the opened openings 34, the strength of the fragrance felt by the wearer or caregiver can be adjusted to a desired level.

[0044] In addition, after using the absorbent article 10, when replacing the used absorbent article 10 with a new absorbent article, the lid material 26 can be completely peeled off, allowing the fragrance to volatilize widely, thereby reducing the odor during care work involving handling the absorbent article 10 after use. 6, the peeled off lid material 26 and adhesive layer 28 can be reused as post-treatment tape after the absorbent article 10 is rolled up when it is disposed of. Also, by completely peeling off the lid material 26 in this way and disposing of the absorbent article 10 with all of the openings 34 open, the fragrance continues to volatilize even inside the trash can, and bad odors inside the trash can can also be suppressed.

[0045] The absorbent article 10 of the present invention may also take another embodiment, as shown in FIG. In the fragrance bag 20 shown in Fig. 7, the inside of the bag body 21 is divided by a heat-sealed section 23, and the fragrance sheet 22 is divided into each compartment and installed as fragrance sheets 22a to 22d. By dividing the fragrance sheet 22 in this way, it is possible to control the volatile fragrance more finely. In addition, fragrance is usually a blend of multiple components, each of which has a role as a top note, a middle note, and a base note. The top note is a fragrance that evaporates easily and gives a refreshing and fresh impression. For example, if only the first opening 34a is opened and the fragrance weakens during continued use, the second opening 34b is opened, and the top note will evaporate again, making it possible to maintain the freshness. In a single fragrance sheet 22 as shown in FIG. 3, the strength of the fragrance can be controlled by the number of openings 34, but since they are connected inside the bag body 21, the top note components contained in the fragrance sheet 22 are weakened overall, and even if the number of openings 34 is increased during use, the strength of the fragrance is restored, but the fresh feeling is not restored.

[0046] Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments and examples. It is clear to those skilled in the art that various modifications and improvements can be made to the above embodiments. In addition, it is clear from the description of the claims that forms with such modifications or improvements can also be included in the technical scope of the present invention.
