Description

[Technical Field]

[0001] The present invention relates to an absorbent article having markings on both sides. [Background technology]

[0002] Generally, an absorbent article is 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.

[0003] The longitudinal dimensions of absorbent articles classified as panty liners or mild incontinence care products vary depending on the severity of the target user's symptoms, with those for users with mild symptoms having shorter longitudinal dimensions.On the other hand, absorbent articles classified as disposable diapers for nursing care have longer longitudinal dimensions, but their estimated absorption capacity is very high, equivalent to the amount of urine voided several times.

[0004] Some care recipients have very little incontinence (not enough to warrant the use of disposable diapers), but due to limitations in their limbs or other reasons, require assistance with toileting and the use of incontinence support products. For these people, it is desirable to use light incontinence support products rather than disposable diapers for their incontinence care, from the perspectives of independence, economy, and ease of assistance. However, the lower the recommended absorption capacity of a light incontinence support product, the shorter its longitudinal dimensions are, and when the caregiver (caregiver) places it on the care recipient's underwear, the front and back positions are often incorrect, creating the problem of the absorbent article easily missing the target area for urination.

[0005] As a prior art absorbent article for solving such problems, for example, Patent Document 1 discloses a sanitary napkin in which a mark is provided on the surface of a cover sheet that covers the surface of the top sheet, located approximately in the center of the absorbent body, to facilitate positioning of the absorbent body relative to clothing, and the mark is colored while the surrounding area around the mark is not colored. Furthermore, Patent Document 2 discloses an absorbent article in which a mark for fixing the absorbent article in an appropriate position is highly visible, making it easy to position the absorbent article. In this absorbent article, a backsheet is provided with a plurality of patterns, and the end flap portion has a window area in which some of the patterns are visible from the skin-facing side, and the patterns visible through the window area include marking patterns that are symmetrical with respect to the vertical center line within the range visible through the window area.

[0007] However, in both Patent Documents 1 and 2, the positioning markers are designed from the perspective of the wearer (person receiving care) rather than the caregiver (person providing care), and since they are not designed from the perspective of the caregiver, they are not intended for both the caregiver and the person receiving care who produces relatively little urine but still requires a certain amount of assistance, and the problem remains that the device cannot be worn properly by such people receiving care (i.e., the caregiver cannot help them wear it properly).

[0008] The present invention has been made in consideration of the above circumstances, and its purpose is to provide an absorbent article that allows a caregiver to accurately know the position of the absorbent body within the absorbent article, and also to know the marker when placing the absorbent article on the clothing of the person being cared for, and the position where the person being cared for will urinate. [Means for solving the problem]

[0009] The inventors conducted extensive research and discovered that by providing markings on both the skin-contacting side and the non-skin-contacting side of an absorbent article having a predetermined longitudinal dimension, and also providing adjustment markings in front of and behind the markings, and further applying a material that develops color when it comes into contact with moisture in a substantially linear pattern across the center of the width of the absorbent article, it is possible to create an absorbent article that allows the caregiver to accurately determine the position of the absorbent body within the absorbent article, and to know the markings when placing the absorbent article on the clothing of the person being cared for, and the position where the person being cared for will urinate, thereby solving the above-mentioned problems and leading to the completion of the present invention. Specifically, the present invention provides the following:

[Effects of the Invention]

[0011] According to the present invention, an absorbent article can be provided that allows a caregiver to accurately know the position of the absorbent body within the absorbent article, and also to know the marker when placing the absorbent article on the clothing of the care recipient and the position where the care recipient will urinate. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is a plan view of an absorbent article of the present invention as viewed from the top sheet side. [Figure 2] 1 is a plan view of an absorbent article of the present invention as viewed from the back sheet side. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, the form for carrying out the present invention (hereinafter referred to as the embodiment) will be described in detail with reference to the drawings. However, these are presented for the purpose of illustration only and are not intended to limit the present invention.

[0014] In the description of this specification, the longitudinal direction of the absorbent article 1 refers to the direction extending from the front to the back of the wearer when the absorbent article 1 is worn, and is the direction indicated by the symbol Y in the drawings. The width direction of the absorbent article 1 refers to the direction horizontal to or perpendicular to the longitudinal direction, and is the direction indicated by the symbol X in the drawings. Furthermore, the skin-contacting surface refers to the surface of each of the front and back surfaces of each component of the absorbent article 1 that faces the skin of the wearer when worn, and the non-skin-contacting surface refers to the surface of each of the front and back surfaces of each component of the absorbent article 1 that faces the side opposite to the skin of the wearer (underwear side) when worn. Furthermore, examples of the absorbent article 1 include light incontinence products in particular.

[0015] <Absorbent articles> Fig. 1 is a plan view of an absorbent article 1 according to an embodiment of the present invention, as viewed from the top sheet 10 side, and Fig. 2 is a plan view of the absorbent article 1 according to an embodiment of the present invention, as viewed from the back sheet 20 side. The absorbent article 1 of the present invention comprises a liquid-permeable top sheet 10, a liquid-impermeable back sheet 20, and an absorbent body 30 between the top sheet 10 and the back sheet 20. The longitudinal dimension of the absorbent article 1 is 200 mm or more and 300 mm or less. The width dimension is preferably 50 mm or more and 170 mm or less. When each dimension falls within the above numerical range, an absorbent article 1 suitable for use as a light incontinence product can be obtained. Furthermore, when the longitudinal dimension of the absorbent article 1 falls within the above numerical range, it is difficult for the absorbent article 1 to be misaligned when worn by the care recipient.

[0016] The absorption capacity of the absorbent article 1 is preferably 20 g or more and 400 g or less. By keeping the absorption capacity within the above range, it is possible to obtain an absorbent article 1 that can be used for care recipients with only minor incontinence. The absorption capacity is measured by immersing the absorbent article (without individual packaging and release paper) in 0.9% saline for 10 minutes, placing the top sheet face down on a wire mesh, and draining for 30 seconds. The change in weight (g) before and after absorption is the absorption capacity. The absorption capacity can be indicated on the product packaging of the absorbent article 1 as the "recommended absorption capacity."

[0017] <Top sheet> The top sheet 10 may be formed from a liquid-permeable substrate that allows urine to move into the absorbent body 30. For example, known hydrophilic nonwoven fabrics such as air-through nonwoven fabrics, thermal-bonded nonwoven fabrics, and spun-bonded nonwoven fabrics may be used. Furthermore, the surface of the top sheet 10 may be embossed or perforated to improve liquid permeability. Any known method can be used for embossing or perforating the top sheet 10 without limitation. Furthermore, to reduce irritation to the skin, the top sheet 10 may contain lotions, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, and the like. From the viewpoints of strength, processability, and liquid return, the basis weight of the top sheet 10 is 13 g / m 2 More than 200g / m 2 Preferably, it is 15 g / m or less. 2 More than 30g / m 2 The following is more preferable: There are no particular restrictions on the shape of the top sheet 10, as long as it has a shape that covers the absorbent body 30 and is necessary to guide bodily fluids to the absorbent body 30 without leakage.

[0018] <Back seat> The backsheet 20 may be formed using a liquid-impermeable substrate that prevents the body fluids held by the absorbent body 30 from wetting clothing, and a plastic film such as a liquid-impermeable polyethylene film that is breathable or non-breathable may be used.

[0019] From the viewpoint of strength and processability, the basis weight of the back sheet 20 is 13 g / m 2 More than 40g / m 2 Preferably, it is 15 g / m or less. 2 More than 30g / m 2 The following is more preferable: To provide breathability to the back sheet 20, for example, a filler may be blended into the resin film of the base material, or the back sheet 20 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without limitation.

[0020] <Absorbent> In the absorbent article 1 of the present invention, the maximum length L of the absorber 30 in the longitudinal direction is preferably 150 mm to 290 mm, and more preferably 200 mm to 290 mm. The maximum width WO of the absorber 30 in the width direction is preferably 60 mm to 120 mm, and more preferably 70 mm to 100 mm.

[0021] (nonwoven fabric) The absorbent body 30 is preferably a nonwoven fabric sheet alone, or a sheet in which superabsorbent polymer (hereinafter also referred to as SAP) particles are fixed between the fibers of the nonwoven fabric sheet. By making the absorbent body 30 in a sheet form, the absorbent body 30 becomes thin, which makes it possible to make the absorbent article 1 easier for caregivers to handle. Note that a commercially available sheet may be used as the sheet in which superabsorbent polymer particles are fixed to nonwoven fabric (SAP sheet). The nonwoven fabric that can be used for the absorbent body 30 may be a hydrophilic nonwoven fabric such as an airlaid nonwoven fabric, or a composite nonwoven fabric in which pulp is woven into a spunbond nonwoven fabric by hydroentangling. An example of such a composite nonwoven fabric is Hydroknit (registered trademark) nonwoven fabric. Hydroknit nonwoven fabric is a trade name of Kimberly-Clark Corporation, USA, and as disclosed in U.S. Patent No. 5,284,703, is a sheet made by firmly entangling pulp into polypropylene nonwoven fabric using high water pressure (water jet) without using a binder (adhesive), and is a material with excellent strength and absorbency.

[0022] (Superabsorbent polymer) The superabsorbent polymer contained in the absorber 30 is not particularly limited as long as it can absorb body fluids and prevent backflow, and can be formed from materials such as sodium polyacrylate, polyaspartate, (starch-acrylic acid) graft copolymer, (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer, and saponified products thereof. Among these, sodium polyacrylate is preferred from the viewpoint of absorption capacity per weight. Furthermore, when the absorbent body 30 contains a superabsorbent polymer, the ratio of the weight of the superabsorbent polymer to the weight of the entire absorbent body 30, i.e., weight of superabsorbent polymer / weight of the entire absorbent body 30 x 100 (%), is preferably 10% or more and 80% or less, and more preferably 20% or more and 70% or less.

[0023] <Landmark> 1 and 2, the absorbent article 1 of the present invention is provided with longitudinal marks 40 on both the skin contacting surface side and the non-skin contacting surface side, at positions that divide the absorbent article 1 into three equal parts in the longitudinal direction, and that run in a substantially straight line across the absorbent article 1 in the width direction. By providing the longitudinal marks 40, when a caregiver puts the absorbent article 1 into the underwear of a care recipient, the longitudinal marks 40 function as marks for aligning the putting position and the position of the absorber 30 with the crotch position of the underwear, making it easier to put on the absorbent article 1.

[0024] The product form of the absorbent article 1 of the present invention is not particularly limited, but it is preferable that it be individually folded, and that longitudinal marks 40 be provided at the positions of the folds in the individually folded package (i.e., longitudinal marks 40 are provided at each of the folds of the absorbent article 1 that is individually folded in thirds). Having the positions of the folds and longitudinal marks 40 aligned makes it easier to align the position of the absorbent article 1 with the crotch position of the underwear.

[0025] 1 and 2, it is preferable that approximately oval adjustment marks 50 are provided at both widthwise ends of the longitudinal mark 40, respectively in front of and behind the longitudinal mark 40. By providing the adjustment marks 50, when the caregiver puts the absorbent article 1 on the care recipient for the second or subsequent time, the caregiver can align the used absorbent article 1 with the new absorbent article 1 and adjust the position of the new absorbent article 1 to match the individual urination position of the care recipient, making it easier to adjust the putting position of the absorbent article 1. In this case, the width dimension of the adjustment mark 50 is preferably 0.2 mm or more and 7 mm or less. Furthermore, the distance between each adjustment mark 50 and the longitudinal mark 40 closest to it in the longitudinal direction, parallel to the longitudinal direction of the absorbent article 1, is preferably 5 mm or more and 10 mm or less. The shape of the adjustment mark 50 is not particularly limited as long as it does not impair visibility, and it may be a substantially rectangular or substantially triangular shape. The adjustment mark 50 may be provided only on the skin-contacting surface of the absorbent article 1, but it is preferable that it is also provided on the non-skin-contacting surface as shown in FIG. 2.

[0026] It is preferable that cutout structures (not shown) be provided in the absorbent article 1 at both widthwise ends of the longitudinal marks 40 and / or at the positions where the adjustment marks 50 are provided. By providing the cutout structures, the alignment points (longitudinal marks 40 and / or adjustment marks 50) are emphasized, making it easier to adjust the wearing position of the absorbent article 1.

[0027] Furthermore, width direction marks 60 indicating the width direction center of the absorbent article 1 are provided at both longitudinal ends of the absorbent article 1. Providing the width direction marks 60 makes the width direction center of the absorbent article 1 stand out, making it easier to find any distortion on the left or right sides of the absorbent article 1 when wearing it undergarments, and thereby making it easier to correct the shape and wearing position of the absorbent article 1. It is preferable that the width direction marks 60 are provided only on the skin contact side of the absorbent article 1, but they may also be provided on the non-skin contact side (not shown).

[0028] The longitudinal markers 40, adjustment markers 50, and width markers 60 described above may be provided on any of the constituent components of the absorbent article 1, but are preferably provided by printing on the backsheet 20, which is easy to print on. There are no limitations on the printing method. Furthermore, when printing only on the backsheet 20, the markers may be obscured when viewed from the skin-contacting side due to overlapping constituent components. Therefore, they can also be printed on the constituent components of the topsheet 10 or absorbent body 30. In such cases, it is preferable to provide the markers by printing with a hot-melt ink. Inkjet printing is preferred as the printing method. There are no particular limitations on the method for ejecting the hot-melt ink, and a thermal method, a piezo method, or the like can be used. Furthermore, the hot-melt ink preferably has a melt viscosity of 0.1 Pa.s or less at 120°C, and more preferably a melt viscosity of 0.06 Pa.s or less.

[0029] Hot-melt inks are not particularly limited as long as they satisfy the melt viscosity requirements described above. Examples of thermoplastic resins that can be used include polyolefins such as polyethylene, mixtures thereof, polyamides, polyesters, polyesteramides, polyvinyl alcohols, cellulose esters, polyvinylpyridines, polyethers, polyethylene, ethylene-vinyl acetate copolymers, copolyesters, olefin-based block copolymer rubbers, polystyrene-acrylic copolymers, terpene resins, rosin fluids, phenolic resins, and coumarone-indene resins. Examples of such hot-melt inks include those sold under the trade name MDL5800 (manufactured by EDM Corporation). The weight percentage of the binder in the hot-melt ink is preferably 20% to 50%, and more preferably 30% to 40%.

[0030] These hot-melt inks may also contain additives such as waxes and oils to improve flow characteristics. For example, polyalkylene waxes (polyethylene wax, polypropylene wax, etc.), Fischer-Tropsch wax, linear primary alcohols, microcrystalline waxes, fatty acids, carnauba wax, candelilla wax, stearic acid amide, paraffin wax, montan wax, ethoxylated long-chain alcohols, etc. may be used. These waxes may be used alone or in combination. The mass ratio of additives in the hot-melt ink is preferably 40% to 70%, more preferably 50% to 60%.

[0031] Furthermore, these hot melt inks may contain inorganic pigments, organic pigments, or dyes, and there are no particular limitations on the types of pigments or dyes that are commonly used in hot melt inks. For example, inorganic pigments such as titanium dioxide (white), carbon black (black), iron oxide (red, yellow, brown), chromium oxide (green), and ferric ammonium ferrocyanide (blue) can be used. For example, organic pigments such as diarylide yellow (pigment yellow), phthalocyanine blue (pigment blue), and red lake (pigment red) can be used. The mass ratio of the pigment or dye in the hot melt ink is preferably 0.1% to 20%, and more preferably 0.5% to 10%.

[0032] These hot melt inks may contain, in addition to the binder, additives, and pigment or dye, a plasticizer, an extender, a thickener, a defoamer, a wetting agent or surfactant, an antioxidant, and the like.

[0033] When inkjet printing these hot melt inks, it is preferable to have a step of setting the temperature of the hot melt ink to 60°C or higher and 150°C or lower, and more preferably 70°C or higher and 120°C or lower.

[0034] <Indicator> In the absorbent article 1 of the present invention, a material that develops color when it comes into contact with water is applied in a substantially linear manner so as to connect the widthwise markers 60. The area where the material is applied is an indicator 70 that develops color when it comes into contact with urine and indicates the urination position, as shown in FIG. 1. The provision of the indicator 70 allows a caregiver to confirm the urination position in a used absorbent article 1, and when putting on a new absorbent article 1 for the second or subsequent time, the caregiver can easily adjust the expected urination position in the new absorbent article 1 (adjust the wearing position of the absorbent article 1). It is preferable that the indicator 70 be provided only on the skin-contacting surface side of the absorbent article 1.

[0035] The material applied to the indicator 70 is preferably a hot-melt ink. The hot-melt ink is preferably the same as the hot-melt ink used to form the longitudinal markings 40, the adjustment markings 50, and the width direction markings 60 described above, and the printing method, etc., used to form the longitudinal markings 40, the adjustment markings 50, and the width direction markings 60 described above is also preferably used. Furthermore, the hot melt ink applied to the indicator 70 contains an indicator (a chemical that develops color when it comes into contact with moisture) instead of a pigment or dye, and the indicator may be one that is commonly used as an indicator, such as ethyl red or bromophenol blue. It is preferable that the hot melt ink is applied continuously to the skin contacting surface of the absorbent article 1 (i.e., the indicator 70 is formed continuously and without interruption on the skin contacting surface of the absorbent article 1).

[0036] Although the present invention has been described above using 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 will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Explanation of symbols]
