Abstract
Description
[0001] This application is a divisional application. The original application was filed on October 9, 2015, with application number 201580054688.4 (PCT / US2015 / 054813) and the invention title was "Adult disposable absorbent articles and series of lengths relative to waist profile and hip profiles relative to side profiles". Technical Field
[0002] This disclosure relates to disposable absorbent articles and a series of disposable absorbent articles designed to fit different adult body sizes, shapes and types, and therefore their sizes are set to fit a wide range of adult consumers. Background Technology
[0003] The "waist circumference" measurement serves as the primary anchor point for absorbent fabrics, as it represents the minimum circumference around the body, especially for women with a more hourglass or pear-shaped figure. This is where the fit is defined (meaning the product's circumference), and therefore the force at the waist must be increased to prevent slippage or sagging due to the increased body dimensions at the hips. "Crotch measurement" and "waist circumference" are shown in... Figure 1 In the middle. For example Figure 2 As shown, the relationship between "crotch width" and "waist circumference" ("crotch width to waist circumference ratio") is an important product design parameter to ensure that the garment length is not excessive. Excessive garment length can result in extra material in the crotch area, leading to sagging, leakage, bulking between the legs and under the garment, and causing material to show above the top of the garment, all of which can negatively impact performance and privacy.
[0004] "Body length" and "waist width" are shown in Figure 3 In the middle. For example Figure 4 and 5 As shown, the "body length to waistline" ratio is related to the "body crotch to waist circumference ratio," because the values of both decrease as BMI and waist circumference increase. This is shown in... Figure 2 , 4 and 5.
[0005] As waist circumference increases with BMI, both the "body crotch-to-waist ratio" and the "body length to waist profile" decrease. A key benefit of bringing the "product length to waist profile" closer to the "body length to waist profile" and designing it to change accordingly with BMI and waist circumference is that the product itself fits the body more closely. This results in significantly less deformation of the product during application compared to products generally designed to fit a wider range (as exhibited by products currently on the market). This also results in a more effective lining effect and less external material that might be visible in the crotch and top of the garment. In fact, many products currently on the market are designed to fit an increment of roughly 100 pounds and therefore do not provide sufficient fit, lining, comfort, and privacy across the entire range. In addition, product designs that mimic the general shape of the body convey a better, more fitting feel to consumers, because the "product length relative to the waistline" is more similar to the consumer's "body length relative to the waistline".
[0006] Another consideration is that some consumers prefer product designs that offer a lower fit so that the front waistline is below the navel. Products designed to fit below the navel and around the waist to the back also fall within the "low-motion" area of the anatomy, as described in US 5,358,500 granted to LaVon et al., thus providing increased product stability, comfort, and support. Products designed to deliver a lower fit relative to the navel will necessarily require a smaller "product length relative to the waistline."
[0007] Another important profile is the "hip-to-side profile of the product." "Hip circumference" and "side length" are shown in... Figure 23 In the middle. For example Figure 24As shown, the relationship between "hip circumference" and "side length" ("hip circumference to side length ratio") is an important product design parameter to ensure that the "relaxed side length" of the garment is neither excessive nor insufficient. Excessive "relaxed side length" can cause material to show above the top of the garment and can lead to improper placement of the waistline; while insufficient "relaxed side length" can result in too little coverage, inappropriate anchoring and product gaps, and improper placement of the waistline, all of which can negatively impact performance and privacy. Appropriate side length ensures that the garment is properly positioned at the wearer's hips and / or waist. Due to its relationship with the hip prominence, the "hip circumference" measurement generally establishes the primary anchor point for absorbent garments, as it represents the maximum circumference around the body in the lower body region. This is especially true for women with a more cylindrical or apple-shaped body. In an alternative implementation, the "waist circumference" measurement can serve as the primary anchor point for the absorbent product, as it represents the minimum circumference around the body, especially for women with a more hourglass or pear-shaped figure. This is the fit at the minimum circumference (which signifies the product's circumference), and therefore the force at the waist must be increased to prevent slippage or sagging due to the increased body dimensions at the hips.
[0008] "Hip width" and "side length" are shown in Figure 25 In the middle. For example Figure 26 and 27 As shown, the "body hip-to-side profile" is related to the "hip circumference to side-to-side length ratio" because the values of both increase with increasing BMI and "waist circumference". This is shown in... Figure 24 , 26 and 27.
[0009] As hip circumference increases with BMI and waist circumference, both the hip circumference-to-side length ratio and the body hip-to-side profile increase. Therefore, for products designed to deliver a fit with a front waist edge close to the navel, as shown in Figure 29a, a key beneficial effect would be a "product hip-to-side profile" that is closer to the "body hip-to-side profile" and designed to change accordingly with BMI and waist circumference. However, for products designed to deliver a lower fit relative to the navel, as shown in Figure 29b, matching the "product hip-to-side profile" to the "body hip-to-side profile" may not necessarily provide a better fit, since the product's edge is located between the waist and hip. The designs permitted by this disclosure are more design-calibrated to provide higher levels of fit, padding effect, comfort, and privacy across a range designed for wearers within the aforementioned BMI range and consumers who desire different types of fit, such as those who prefer a lower fit relative to the navel.
[0010] The adult incontinence (“AI”) absorbent articles disclosed herein can be used to absorb and contain fluids and other excretions excreted from the body to prevent soiling of the body and clothing. For adults with urinary incontinence, urine excretion consists of two general types: stress urinary incontinence (“SUI”) and squeeze urinary incontinence (“UUI”). SUI is caused by high pressure on the bladder, induced by coughing, sneezing, laughing, bending over, etc., and can result in a high flow rate, but the urine volume is smaller than that associated with UUI. UUI can result in full bladder release, but the flow rate is lower than that associated with SUI.
[0011] Adult incontinence products come in a variety of designs, each typically available in multiple sizes, including 2, 3, and 4 size ranges. The size of prior art products generally influences, for example, the size of the waist opening, the size of the opening around the thighs, and the length or "pitch" of the garment. Many of these prior art products are designed to fit a range up to 100 pounds. Prior art products are typically sized and sold based on waist circumference scales. These various sizes can have waist circumference ranges of up to 12 inches for a given size and, in some cases, up to 16 inches. Given the wide range associated with these various sizes, if a consumer selects a size of prior art adult incontinence product based on the wearer's waist circumference scale, for example, the thigh opening or pitch of the garment may be too large to fit properly, potentially leading to slippage, sliding, sagging, drooping, or loss of the liner effect designed to suppress leakage. Alternatively, depending on where the wearer is within the said large size range, the thigh opening or pitch of the garment may be too small to fit properly, which could cause discomfort to the wearer, leave skin marks on the wearer's skin, or result in the garment being improperly applied or positioned on the wearer.
[0012] Advantageously, adult absorbent products should be designed and sized to maintain contact and conform as closely as possible to the wearer's body. This conformal design increases the effectiveness of the adult absorbent product by reducing the possibility that urine, etc., will spread or travel along the wearer's body and leak from the adult absorbent product instead of being absorbed into it. However, current adult absorbent products on the market do not adequately address the issue of body shape or product shape, and therefore do not adequately fit a wide range of users or provide the desired level of close fit. Typically, adult incontinence packaging markings indicate that the packaged product is designed to fit the recommended waist circumference range of the wearer. Therefore, waist circumference is often the only standard used to identify the size of adult incontinence products. Waist circumference alone is insufficient to describe an individual's body shape and therefore cannot help define hip or thigh circumference, nor can it define the pitch required to provide an appropriate fit, comfort, coverage, and padding effect for the product. Similarly, even though other characteristics and body size attributes of possible wearers (e.g., age, height, weight, thigh circumference, protrusion) can vary widely within the recommended waist circumference range, and even if the wearer's waist circumference falls within this range, it may still result in an ill-fitting garment. There is a need for adult absorbent garments that conform well to the body shapes and sizes of a wide range of wearers. While a wide range of body shapes and sizes exists among women, available products do not reflect this wide range; instead, absorbent garments available today within a given product line tend to be proportional to each other and do not even conform to the natural trend of body shapes and sizes varying across the consumer range, from smaller to larger women and women with different shapes.
[0013] However, Body Mass Index (BMI) has been rising for both men and women globally. In the United States alone, more than one-third of adult women are now considered obese (BMI > 30). This has changed significantly in the past 30 years; in 1980, only about 16% of adult women in the United States were obese. Larger women exhibit different body dimensions than smaller women; that is, all body dimensions do not simply increase proportionally with a woman's size. Furthermore, women can have very different body shapes within the aforementioned BMI range. Current manufacturers of adult absorbent products lack awareness and understanding of this issue, and therefore, consumer needs are not being adequately met. Therefore, there is a need to develop adult absorbent products for a wide variety of body shapes and sizes to provide an improved level of fit and contact between the body and the absorbent product, thereby reducing leakage and improving the overall fit, comfort, coverage, and privacy of the product. Clearly, there is a need for adult absorbent products designed for a variety of wearers based on the wearer's BMI and body shape. The beneficial effects of such customized adult absorbent products need to be communicated to the wearer in an easily understandable way (e.g., some women may not understand what BMI is or know their BMI value), and in a way that is not unpleasant (e.g., based on their BMI, without being disrespectful to women or making them feel embarrassed).

[0048] Figure 29b shows a product designed to fit below the consumer's navel. Detailed Implementation
[0049] The term “overcoat” or “trousers” refers to an garment having a defined waist opening and a pair of leg openings, and being worn on the wearer’s body by inserting the legs into the leg openings and pulling the garment up to the waist.
[0050] "Disposable" refers to clothing that is not intended to be washed or otherwise restored or reused as clothing (i.e., it is intended to be discarded after one use and to be recycled, composted, or otherwise disposed of in an environmentally compatible manner). Overgarments can be "absorbent" so that they can absorb and contain various excretions from the body.
[0051] "Closed" refers to a joint between the lumbar regions to form a continuous lumbar and leg opening. The lumbar region can be permanently joined, semi-permanently joined, or repeatedly tightened. See also Figure 15-17 .
[0052] A “collection” refers to a display of packages comprising single-use articles of different sizes, which have similar article constructions (e.g., the same elastomeric material in flaps, graphic elements [compositionally and / or structurally]), the packages have the same brand and / or sub-brand, and the packages are arranged adjacent to each other in a given area of a retail store. Collections are sold as a series of products, which typically have similar packaging elements (e.g., type of packaging material, film, paper, main color, design theme, etc.) that convey to consumers the message that the different individual packages are part of a larger collection. Collections typically have the same brand, such as “Depend,” and the same sub-brand, such as “forWomen Underwear.” Different collections may have the brand “Depend” and the sub-brand “Silhouette For Women.” The differences between the “for Women Underwear” collection and the “Silhouette For Women” collection include the different elastomeric materials in the flaps, where “for Women Underwear” includes strands as the elastomeric material, and “Silhouette For Women” includes a membrane elastomeric material. In addition, the packaging is noticeably different in that "for Women Underwear" is mainly packaged in a green plastic bag, while "Silhouette For Women" is mainly packaged in a brownish-red box.
[0053] Another example of a "series" as two separate "series" under the same brand "Certainty" is that one series has a sub-brand "Women's Underwear." Different series may have the same brand "Certainty" and the sub-brand "Smooth Shape Briefs for Women." The differences between the "Women's Underwear" and "Smooth Shape Briefs for Women" series include the different elastomer materials used in the side panels; "Women's Underwear" uses strands as the elastomer material, while "Smooth Shape Briefs for Women" uses a membrane elastomer material. Additionally, a noticeable difference in packaging is that "Women's Underwear" is primarily packaged in blue film bags, while "Smooth Shape Briefs for Women" is primarily packaged in brownish-red boxes.
[0054] The series also often shares the same trademarks, including trademarks for the brand, sub-brands, and / or the characteristics and / or benefits of the entire series.
[0055] "Online series" refers to a series distributed through commonly used online sources.
[0056] "Waist width" is defined as the width of the body measured horizontally at the center of the navel (the area around the navel) in the front of the body. See also Figure 3 .
[0057] "Body length" refers to the vertical distance from the navel to the point of maximum depth of the crotch, determined by the maximum depth of the crotch within the longitudinal bisecting plane. See also Figure 3 .
[0058] "Waist circumference" refers to the horizontal circumference of the waist measured horizontally at the level of the center of the navel (umbilicus) while the body is upright. See also Figure 1 .
[0059] "Crotch length" refers to the surface distance of the subject's back measured through the groin and across the middle of the buttocks, from the center of the navel (the area around the navel) to a point at the level of the navel. See also Figure 1 .
[0060] "Crotch-to-waist ratio" refers to the ratio of "crotch width" (mm) to "waist circumference" (mm). See also Figure 1 .
[0061] "Body length to waistline" refers to "body length" (mm) divided by "waist width" (mm). See also Figure 3 .
[0062] "Product length to waistline" refers to the "relaxed product length" of 300 (mm) divided by the "relaxed product waistline width" of 302 (mm). See also Figure 6 .
[0063] "Series Average Product Length to Waist Profile" refers to the average "product length to waist profile" for each size offered in the product series. For example, Depend Underwear for Women (Max Absorbency) is sold and distributed in three sizes: "Small / Medium"; "Large"; and "Extra Large". The "Series Average Product Length to Waist Profile" is the average of the following: "Product Length to Waist Profile" for the Small / Medium size; "Product Length to Waist Profile" for the Large size; and "Product Length to Waist Profile" for the Extra Large size. Table 1 shows examples of "Product Length to Waist Profile" for some currently sold product series.
[0064] "Hip circumference" refers to the body circumference measured horizontally while standing at the level of the widest posterior hip bulge. See also Figure 23 .
[0065] "Hip width" refers to the horizontal distance at the hips in front of an upright body, where, when viewed from the side, the hips are defined at the same level as the point of maximum hip prominence. See also Figure 25 .
[0066] "Lateral length" refers to the vertical distance from the navel to the level of the hip (where, when viewed from the side, the hip is defined at the point of maximum hip prominence). See also Figure 25 .
[0067] The "hip circumference to lateral length ratio" refers to the hip circumference (mm) divided by the lateral length (mm). See also Figure 23 .
[0068] "Hip-to-side profile" refers to the "hip width" (mm) divided by the "side length" (mm). See also Figure 25 .
[0069] "Product hip-to-side profile" refers to the "relaxed product hip width" (301 mm) divided by the "relaxed product side length" (303 mm). See also Figure 6 .
[0070] "Series Average Product Hip-to-Side Profile" refers to the average "product hip-to-side profile" for each size offered in a product series. For example, Depend Underwear for Women (Max Absorbency) is sold and distributed in a series of three sizes: "Small / Medium"; "Large"; and "Extra Large". The "Series Average Product Hip-to-Side Profile" is the average of the following: the "product hip-to-side profile" for the Small / Medium size; the "product hip-to-side profile" for the Large size; and the "product hip-to-side profile" for the Extra Large size. Table 3 shows examples of the "product hip-to-side profile" for some currently sold product series.
[0071] "Relaxed product length" refers to the longitudinal distance between the furthest point in the crotch area and the furthest point along the front waistline. This longitudinal distance is measured parallel to the product's longitudinal axis. (Reference) Figure 6 .
[0072] "Loose product hip width" refers to the lateral distance from the furthest point on the left side of the product at the top edge of the left leg opening to the furthest point on the right side of the product at the top edge of the right leg opening. (Reference) Figure 6 Lateral distance is measured perpendicular to the longitudinal axis of the product.
[0073] "Loose product waist width" refers to the lateral distance from the furthest point on the right side of the front waistline to the furthest point on the left side of the front waistline. This lateral distance is measured perpendicular to the product's longitudinal axis. (Reference) Figure 6 .
[0074] "Relaxed product side length" refers to the straight-line distance from the intersection of the waistline and side edge of the product to the intersection of the top of the leg opening and the same side edge of the product. The relaxed product side length measurement is the average of measurements taken from the left and right sides of the product. (Reference) Figure 6 .
[0075] "Target waist range" refers to the waist range specified on each product package. For example, Depend for Women medium absorbency small / medium packages indicate a waist range of 28-40 inches (71-102 cm).
[0076] "Average Target Waist" refers to the average of the "Target Waist Range". For example, Depend for Women Medium Absorbency Small / Medium has a "Target Waist Range" of 71–102 cm (as defined on its packaging). The "Average Target Waist" for this product is 86.5 cm.
[0077] Consumers suffering from urinary incontinence often experience significant distress due to the condition. Many aspects of this condition contribute to this distress, such as the fear of incontinence in public. Even when wearing absorbent fabrics, there is a persistent fear of leakage and the possibility that the fabric might be noticed under clothing. Therefore, one of the objectives of this disclosure is to provide a product experience that helps normalize this condition by offering a more bra-like, thin, and body-fitting structure across the entire BMI range.
[0078] Body Mass Index (BMI) is a classification system for body shape based on height and mass. BMI can be calculated as follows: BMI includes different categories of weight, including: underweight (BMI < 20), normal weight (BMI 20–25), overweight (BMI 25–30), obese (BMI 30–40), and morbidly obese (BMI > 40).
[0079] Figure 7 This illustrates how a woman's body shape typically changes as her BMI increases. Figure 8 The diagram illustrates several specific shapes that can exist within each BMI category: rectangular (also known as cylindrical), hourglass, pear, and apple. The higher her BMI, the more to the right (towards apple) a woman typically is on that body shape scale. The incidence of these shapes varies across BMI ranges; for example, women with higher BMIs are more likely to be apple-shaped or pear-shaped. Adult absorbent products can be marketed to women with specific body shapes such as apple-shaped, rather than focusing on precise BMI values (which could be unpleasant for consumers), in order to match the wearer with products that best fit her unique body shape or size.
[0080] One area where a woman's body shape changes as her BMI increases is in the "body length to waistline" ratio. On average, the "body length to waistline" ratio becomes smaller for larger women. Figure 4 and 5 This shows how "body length versus waistline" changes when both BMI and "waist circumference" become larger.
[0081] It may be desirable to link the "product length to waistline" with the "body length to waistline" of the target consumer to achieve products with better fit, better shape, and better padding. This increases wearing comfort for each consumer while reducing leakage. Furthermore, product lines where each subsequent larger size's "product length to waistline" follows the same general trend as each subsequent larger size's "body length to waistline" can also deliver products with better fit and better shape to each consumer, regardless of their corresponding BMI.
[0082] While today's adult incontinence product lines are not calibrated to consumers' BMI, they are calibrated to their "waistline". Table 1 details some of the product lines currently on sale ("Comparative Series" or "Existing Product Lines"). Figure 9 This illustrates a comparison of the "product length to waist profile" for these product lines with the "body length to waist profile" of consumers. It is evident that for these comparative product lines with three or more sizes, their "product length to waist profile" not only fails to match those of their target consumers, but also, from size to size, the existing product lines show a trend towards a larger "product length to waist profile," rather than a smaller one as the consumers' "body length to waist profile" might suggest. The result of this mismatch is that these products offer a poorer level of fit, comfort, coverage, and padding performance across most of the BMI range compared to products designed to conform to anthropometric measurements within the same BMI range.
[0083] Table 2 below shows several series of 2, 3, and 4 packages of the present invention with a low-fit design (Figure 29b), whose "product length to waist profile" matches the trends of the consumers they are calibrated to fit, thereby providing better fit and comfort, and thus reducing the possibility of leakage. These series of the present invention are provided only as non-limiting examples. Other series of the present invention are also possible within the scope of this disclosure. These series of the present invention are also shown in Figure 10 and 11 middle.
[0084] Table 3 and Figure 28 The invention series with low cuts shows that the "product hip-side profile" does not follow the trend of the "body hip-side profile" and is consistent with the existing product series.
[0085] Absorbent products The absorbent articles disclosed herein are generally designed and constructed to manage bodily outflows such as urine, menstrual fluid, feces, or other vaginal secretions.
[0086] In one embodiment, an absorbent article may include a base structure comprising a top sheet, a bottom sheet, and an absorbent core at least partially disposed between the top sheet and the bottom sheet. The absorbent base structure may include a waistband, leg cuffs, and / or elastic strands. In various embodiments, reference is made to… Figure 12 The exemplary absorbent article 10 is shown in a flat, unshrinked state prior to its engagement fastening parts 53a and b.
[0087] In one implementation, reference Figure 12 One end of the absorbent article 10 may be configured as a front waist region 36, and the longitudinally opposite end may be configured as a rear waist region 38. The middle portion of the absorbent article 10 extending longitudinally between the front waist region 36 and the rear waist region 38 may be configured as a crotch region 37. In one embodiment, although not shown, the length of each of the front waist region 36, the rear waist region 38, and the crotch region 37 may be, for example, about one-third of the length of the absorbent article 10. In other embodiments, the length of each of the front waist region 36, the rear waist region 38, and the crotch region 37 may have other dimensions. In various embodiments, the absorbent article 10 may have a laterally extending front waist end edge 136 in the front waist region 36 and a longitudinally opposite and laterally extending rear waist end edge 138 in the rear waist region 38.
[0088] In one implementation, reference Figure 12 The base structure 100 of the absorbent article 10 may include a first longitudinally extending side 137a and a laterally opposing second longitudinally extending side 137b. Both sides 137 may extend longitudinally between a front waist end 136 and a rear waist end 138. The base structure 100 may form a portion of a laterally extending front waist end 136 in the front waist region 36 and a portion of a longitudinally opposing and laterally extending rear waist end 138 in the rear waist region 38. Furthermore, the base structure 100 may also include an inner surface 102, an outer surface 104, a longitudinal axis 42, and a transverse axis 44. The longitudinal axis 42 may extend through the midpoint of the front waist end 136 and through the midpoint of the rear waist end 138, while the transverse axis 44 may extend through the midpoint of the first side 137a and through the midpoint of the second side 137b.
[0089] In various embodiments, a portion or all of the absorbent article 10 may be manufactured to be laterally stretchable. The stretchability of the absorbent article 10 may be desired to allow it to conform to the wearer's body during movement. This stretchability may also be desired, for example, to allow caregivers to extend the front waist area 36, back waist area 38, crotch area 37, and / or the base structure 100, thereby providing additional body coverage for wearers of different body types, i.e., customizing the absorbent article 10 for an individual wearer. Such extension may give the absorbent article 10 a generally hourglass shape, provided that the crotch area 37 is extended to a relatively smaller extent than the waist areas 36 and / or 38. This extension may also give the absorbent article 10 a fitted appearance during use.
[0090] Any part or all of the absorbent article may include the phage composition as described in U.S. Serial No. 61 / 931,229, entitled DISPOSABLE ABSORBENT ARTICLES COMPRISING BACTERIOPHAGES AND RELATED METHODS, filed January 24, 2014.
[0091] Top film In one implementation, reference Figure 12 and 19 The absorbent article 10 may include a top sheet 81. The top sheet 81 may be flexible, soft to the touch, and non-irritating to the wearer's skin, and may be elastically stretchable in one or more directions. Furthermore, the top sheet 81 may be liquid-permeable, allowing liquids (e.g., menstrual fluid, urine, and / or loose stools) to permeate its thickness. Various top sheets may also include, for example, hydrophilic materials configured to draw bodily fluids into the absorbent core of the base structure 100 (when these fluids are expelled from the body). Suitable top sheets 81 may be made from a wide variety of materials, such as woven and nonwoven materials, open-cell or hydroformed thermoplastic films, open-cell nonwoven materials, porous foams, honeycomb foams, honeycomb thermoplastic films, and / or thermoplastic woven fabrics. Suitable open-cell membranes may include those described in U.S. Patents 3,929,135, 4,324,246, 4,342,314, 4,463,045, 5,006,394, 5,628,097, 5,916,661, 6,545,197, and 6,107,539.
[0092] Perforated membranes or nonwoven topsheets typically allow bodily exudates to pass through without absorbing them, and reduce the tendency to allow fluids to flow back and seep back into the wearer's skin. Suitable woven and nonwoven materials may include natural fibers, such as wood or cotton fibers; synthetic fibers, such as polyester, polypropylene, or polyethylene fibers; or combinations thereof. If the topsheet 81 comprises fibers, the fibers may be, for example, spunbond, carded, wet-laid, meltblown, hydroentangled, or otherwise processed, as is generally known in the art.
[0093] The top sheet may include a skin lotion. Suitable lotions include, but are not limited to, those described in U.S. Patents 5,607,760; 5,609,587; 5,635,191; 5,643,588; and 5,968,025, and those described in U.S. Patent Application 61 / 391,353.
[0094] In one implementation, the top panel may include graphics (e.g., Figure 15 (116 in the text), which creates a sense of depth, as described in U.S. Patent 7,163,528.
[0095] negative In one implementation, reference is made to, for example Figure 18 and 19 The absorbent article 10 may include a backing sheet 83. The backing sheet 83 may be impermeable or at least partially impermeable to fluids or bodily excretions (e.g., menstrual flow, urine, and / or loose stools) and may be made of a thin plastic film, although other flexible, liquid-impermeable materials may also be used. The backing sheet 83 prevents the absorption of bodily excretions or fluids contained in the absorbent core of the absorbent article 10 from wetting articles in contact with the absorbent article 10, such as sheets, pajamas, clothing, and / or underwear. The backing sheet 83 may include woven or nonwoven materials, polymer films such as thermoplastic films of polyethylene or polypropylene, and / or multilayer materials or composites, including films and nonwoven materials (e.g., having an inner film layer and an outer nonwoven layer). A suitable backing sheet may include a polyethylene film having a thickness of about 0.012 mm (0.5 mils) to about 0.051 mm (2.0 mils). Examples of polyethylene films are manufactured by Clopay Corporation (Cincinnati, Ohio) under the names BR-120 and BR-121, and by Tredegar Film Products, Terre Haute, Ind. under the name XP-39385.
[0096] A suitable material for film may be a liquid-impermeable thermoplastic film having a thickness of about 0.012 mm (0.50 mils) to about 0.051 mm (2.0 mils), such as polyethylene or polypropylene. Typically, the film may have a thickness of about 5 g / m³. 2 Approximately 35g / m 2 The substrate is typically positioned adjacent to and bonded to the outer surface of the absorbent core. For example, the substrate can be attached to the absorbent core by a uniform, continuous layer of adhesive, a patterned layer of adhesive, or a series of separate adhesive lines, spirals, or dots. Illustrative, but not limiting, adhesives include those manufactured by HB Fuller Company (St. Paul, Minn., USA) and sold under HL-1358J. An example of a suitable attachment device comprising an open-patterned network of adhesive filaments is disclosed in 4,573,986. Another suitable attachment device comprising a plurality of adhesive filaments coiled in a spiral pattern is illustrated by the apparatus and methods shown in the following patents: 3,911,173; 4,785,996 and 4,842,666. Alternatively, the attachment element may comprise a thermally bonded element, a pressure bonded element, an ultrasonically bonded element, a dynamic mechanical bonded element, or any other suitable attachment element or combination of these attachment elements.
[0097] In one embodiment, the film 83 may be embossed and / or textured to provide a more fabric-like appearance. Furthermore, the film 83 may allow vapor to escape from the absorbent core of the absorbent article 10 (i.e., the film 83 is breathable) while still preventing or at least inhibiting the passage of fluids or bodily exudates through the film 83. In one embodiment, the dimensions of the film 83 may depend on the dimensions of the absorbent article 10 and, for example, the design or configuration of the absorbent article 10 to be formed.
[0098] Absorption core In various implementation schemes, refer to Figure 18 and 19The absorbent article 10 may include an absorbent core (also referred to as an "absorbent member," "absorbent assembly," "absorbent structure," or "absorbent composite") 200 disposed between a top sheet 81 and a bottom sheet 83. The absorbent core 200 may include a laterally extending front edge 236 in a front waist region 36, a longitudinally opposing and laterally extending rear edge 238 in a rear waist region 38, a first longitudinally extending side 237a, and a laterally opposing second longitudinally extending side 237b. Both side edges 237 may extend longitudinally between the front edge 236 and the rear edge 238. In one embodiment, more than one absorbent core 200 or more absorbent core layers may be provided in the absorbent article 10. The absorbent core 200 may be any suitable size or shape compatible with the absorbent article 10. Exemplary absorbent structures that have gained widespread acceptance and commercial success and can be used as absorbent core 200 of this disclosure are described in U.S. Patents 4,610,678, 4,673,402, 4,888,231 and 4,834,735.
[0099] In one embodiment, a suitable absorbent core may comprise a cellulose breathable felt material. For example, such an absorbent core may comprise less than about 40%, 30%, 20%, 10%, 5%, or even 1% of the cellulose breathable felt material by weight. In addition, such an absorbent core may consist primarily of an absorbent gelling material in an amount by weight of at least about 60%, 70%, 80%, 85%, 90%, 95%, or even about 100%. Furthermore, a portion of the absorbent core may also comprise microfiber adhesive (if applicable). Such absorbent cores, microfiber adhesives, and absorbent gelling materials are described in U.S. Patents 5,599,335; 5,562,646; 5,669,894; 6,790,798; and 7,521,587, as well as U.S. Patent Publication 2004 / 0158212.
[0100] In one embodiment, the core (including multiple layers constituting the core system) can be printed and embossed, as described in U.S. Patent 8,536,401.
[0101] In one embodiment, the core may be separable from the base structure, as disclosed in U.S. Patents 6,989,006; 7,381,202; 7,175,613; 7,824,386; 7,766,887 and 6,989,005. In such embodiments, the measurements described in this disclosure may be performed on the base structure alone or in conjunction with the separable core / absorber assembly.
[0102] In one embodiment, the absorbent article of this disclosure, particularly the portion wherein the absorbent member is disposed, may have a body fluid absorption rate greater than 3 g / sec according to U.S. Patent 6,649,810. According to U.S. Patent 6,649,810, the phrase "the portion of the absorbent article wherein the absorbent member is disposed" is intended to refer to the portion occupied by the absorbent member when the absorbent article is flat, undisturbed, and viewed in its plan view.
[0103] In one embodiment, the absorbent structure may have an uptake factor greater than 3 according to U.S. Patent 7,073,373, wherein the uptake factor is defined as absorbent core permeability divided by normalized retention capacity (which is defined by a “retention capacity test” – also according to U.S. Patent 7,073,373).
[0104] In one embodiment, the absorbent complex has a concentration greater than 75 g / 100 cm³ according to U.S. Patent 6,649,810. 2 Its body fluid absorbability.
[0105] In one embodiment, the target location of the absorbent article may have a wicking value greater than 36% according to U.S. Patent 6,383,960.
[0106] In one embodiment, the absorbent article may have a flexural stiffness between 0.05 and 1.0 gf, according to U.S. Patent 5,810,796.
[0107] In one embodiment, the absorbent article may have a crotch fluid absorption rate greater than 3 g / sec according to U.S. Patent 6,649,810. In one embodiment, the freeze-dried composite of the absorbent complex may have an uptake rate of at least about 1.9 cubic centimeters (cc) of liquid / second at 80% composite saturation according to U.S. Patent 6,689,934.
[0108] Leg braces In one implementation scheme, see Figure 13 and 14The base structure 100 of the absorbent article 10 may include longitudinally extending and laterally opposed leg cuffs 147a and 147b, which are disposed on the inner surface of the base structure 100 facing inward and contacting the wearer. Leg cuffs 147a and 147b may include one or more resilient tightening members disposed at or near the proximal edge of one or both of the leg cuffs 147. Furthermore, the resilient tightening members of the leg cuffs may also include one or more elastomeric elements 146 disposed at or near the distal edge of one or both of the leg cuffs 147. The resilient leg cuffs 147 may include several embodiments intended to reduce bodily exudates or fluid leakage in the leg area. The resilient leg cuffs 147 are sometimes referred to as leg bands, blocking cuffs, elastic cuffs, or bushing cuffs. Suitable resilient leg clamps 147 may include those described in U.S. Patents 3,860,003, 4,909,803, 4,695,278, 4,795,454, 4,704,115, and 4,909,803, and U.S. Patent Publication 2009 / 0312730. Leg clamps 147 may be formed by folding portions of the base structure 100 laterally inward, i.e., toward the longitudinal axis 42, thereby simultaneously forming the respective leg clamps 147 and the sides 137a and b of the base structure 100. In other embodiments, leg clamps 147 may be formed by attaching one or more additional layers to or adjacent to each respective side 137a and 137b of the base structure 100. In one embodiment, the base structure 100 may also include other elastic members disposed adjacent to the side 137, which, when allowed to relax and thus pull the inner surface 102 of the front waist region 36 toward the inner surface 102 of the rear waist region 38, allow the article 10 to be shaped into a “U” shape.
[0109] In one embodiment, each leg cuff 147 may include proximal edges 157a and 157b. These edges 157a and 157b are positioned adjacent to the longitudinal axis 42 relative to the distal edges 139a and 139b. The leg cuffs 147 may overlap the absorbent core 200, i.e., the proximal edges 157a and 157b are laterally inward of the corresponding sides 237a and 237b of the absorbent core 200. This overlapping configuration is desirable in order to give the absorbent article 10 a more finished appearance than that given by a non-overlapping configuration. In other embodiments, the leg cuffs 147 may not overlap the absorbent core 200.
[0110] In one embodiment, each leg cuff 147 may be attached to the inner surface 102 of the base structure 100 in a leg cuff attachment area (not shown) adjacent to the front waist end edge 136 and in a longitudinally opposing leg cuff attachment area (not shown) adjacent to the rear waist end edge 138. In one embodiment, between the leg cuff attachment areas, the proximal edge 157 of the leg cuff 147 remains free, i.e., not attached to the inner surface 102 of the base structure 100 or the absorber core 200. Furthermore, between the longitudinally opposing leg cuff attachment areas, each leg cuff 147 may include one or more (specifically, one, two, three, or four elastic strands / leg cuffs 147) longitudinally extendable cuff elastic tightening members 159, which may be provided or arranged adjacent to the proximal edge 157 of the leg cuff 147 by any suitable method. Each of such cuff elastic tightening members 159 may be connected along the entire length of the leg cuff or only a portion of the leg cuff length. For example, such a hoop elastic tightening member 159 may be attached only at or near the longitudinally opposite ends of the leg hoop, and may be attached at the midpoint of the leg hoop length. Such a hoop elastic tightening member 159 may be disposed in the crotch area 37 and may extend into one or both of the front waist area 36 and the rear waist area 38. For example, the elastic tightening member 159 may be attached at or near the proximal edge 157 of each leg hoop 147 and extend into both the front waist area 36 and the rear waist area 38.
[0111] In various embodiments, each of the resilient tightening members 159 may be enclosed within, for example, folded edges. In various embodiments, the hoop resilient tightening member 159 may be sandwiched between the two layers forming the leg hoop 147 by the two layers of the base structure 100, or may be attached to the surface of the base structure 100 or the leg hoop 147 and remain exposed.
[0112] In one embodiment, when stretched, a hoop elastic tightening member 159 disposed adjacent to the proximal edge 157 of each leg cuff allows the proximal edge 157 of the leg cuff to extend to a flat, unshrunken length of the base structure 100, such as the length of the base structure 100. When relaxed, the hoop elastic tightening member 159 contracts to pull the front waist area 36 and the back waist area 38 toward each other, thereby bending the article 10 into a “U” shape, wherein the interior of the “U” shape can be formed by the portion of the article 10 intended to be positioned toward the wearer’s body (i.e., the inner surface 102). Since each of the proximal edges 157 remains free between the longitudinally oriented leg cuff connecting areas, the contractile force of the elastic tightening member 159 can lift the proximal edge 157 of the leg cuff 147 away from the inner surface 102 of the base structure 100. When the article 10 is in a relaxed state, this lifting of the proximal edge 157 raises the leg cuff 147 into a position serving as a lateral barrier to prevent or at least inhibit leakage of bodily fluids.
[0113] belt In one implementation, reference Figure 14 Article 10 may include elastic waistbands 112a and 112b. The elastic waistbands provide improved fit and restraint and can be configured to laterally elastically expand and contract to dynamically conform to the wearer's waist. The elastic waistbands may extend longitudinally outward from the waist edge of the absorbent article 10 toward the waist edge of the absorbent core 200. In one embodiment, the absorbent article 10 may have two elastic waistbands, one positioned in the rear waist region 38 and the other positioned in the front waist region 36, but other trouser embodiments may also be constructed using a single elastic waistband. The elastic waistbands can be constructed in a variety of different configurations, including those described in U.S. Patents 4,515,595 and 5,151,092.
[0114] In one embodiment, the elastic waistband may comprise a material that has been “pre-strained” or “mechanically pre-strained” (i.e., subjected to a degree of localized mechanical stretching to permanently elongate the material). These materials may be pre-strained using a suitable deep embossing technique. In other embodiments, these materials may be pre-strained by guiding the material through an incremental mechanical stretching system as described in U.S. Patent 5,330,458. The materials can then be allowed to return to their substantially unstretched state, thereby forming a zero-strain tensile material capable of stretching at least to the initial stretch point. Examples of zero-strain materials are disclosed in U.S. Patents 2,075,189, 3,025,199, 4,107,364, 4,209,563, 4,834,741, and 5,151,092.
[0115] wing The winglet 189 (ad) may be discrete from or integral with the base structure 100. Discrete winglets are shaped as independent elements that attach to the base structure 100. In some embodiments, this includes multiple winglets, such as two or four (often referred to as lugs or side wings), which attach to the sides 137a and b of the base structure in the front waist region 36 and / or rear waist region 38 (see [link to relevant documentation]). Figure 12-17 In other embodiments, this may include a front stripe and / or a rear stripe (“strip”) that span the front and rear waist regions of the base structure 100, at least across the end edges 136 and 138 of the base structure (see [link]). Figure 12 and 19 In some implementations, the belt 112 may overlap with flaps to create a continuous belt-like structure (see [link]). Figure 14 In an alternative embodiment, the belt may extend beyond the end edge of the base structure, and the belt may form a waistband portion of the article.
[0116] A stripe may include an inner nonwoven layer and an outer nonwoven layer, as well as an elastic component between them. Adhesives or thermoplastic adhesives may be used to bond the inner and outer nonwoven layers. Various suitable stripe configurations can be found in U.S. Patent 2013 / -0211363.
[0117] An integral winglet is part of a base structure, or one or more layers, that project laterally outward from its longitudinal edge. This integral winglet can be shaped to include the winglet projection by cutting the base structure.
[0118] Although many of the embodiments with strap-like flaps described in the patent application are trouser-shaped articles, adhesive articles may also have strap-like flaps disposed in one or two waist areas.
[0119] The structure of the flaps plays a crucial role in the function of the absorbent article and is fundamentally different from the elastic components used in underwear. As mentioned above, incontinence events, such as SUI and UUI, can result in high flow rates and / or complete bladder release. The amount of urine expelled during an incontinence event can vary greatly depending on the type of urinary incontinence and other factors such as the time since the last urination, fluid intake, whether it is day or night. Loading volumes can range from as low as a few drops of urine to as high as 600 ml. Single loading volumes as high as 300, 400, and even 500 ml are not uncommon. These levels of loading volumes result in a significant downward force associated with the loading, which can be one pound or more. This downward force must be compensated by the underlying structure of the absorbent article to minimize sagging, gaps, and leakage. To maintain the fit of the article even after loading, the article includes an elastomeric element 146 (including membranes and / or strands) disposed adjacent to and along the side seams 280a and b of the article (see, for example...). Figure 15 The elastomeric element 146 is adjacent to and terminates along the length of seams 280a and b, and extends laterally from one side to the other. These elastomeric elements should exert a normal force on the body sufficient to anchor the article. The position of the elastomeric elements and the force exerted by the elastomeric elements can be varied to ensure proper anchoring at the hip and along the body, specifically across the front waist area and in the back waist area. One form of anchoring that facilitates maintaining the fit of a loaded article is disclosed in U.S. Patent 5,358,500 Absorbent Articles Providing Sustained Dynamic Fit, granted to LaVon et al. on October 25, 1994. It should also be noted that conventional underwear with elastic components along the waist and leg edges typically will not provide sufficient support to maintain the fit of an underwear if a weight of 300-600 grams is applied to the crotch area.
[0120] Fastening system The absorbent article may also include a fastening system. When fastened, the fastening system interconnects the front waist area 36 and the back waist area 38, thereby allowing it to wrap around the wearer's waist during wear of the absorbent article 10. This can be achieved by interconnecting flaps 189a and b in the back waist area with flaps 189c and d in the front waist area, or by interconnecting flaps in the back waist area with the base structure 100 in the front waist area. The fastening system may include fastening components 53a and b, such as those with protrusions, hook-and-loop fastening components, interlocking fasteners such as inserts and slits, buckles, buttons, snaps, and / or androgynous fastening components, but any other known fastening components are generally acceptable. The fasteners are releasable to engage with a landing area 118, which may be a woven or nonwoven material. Some exemplary surface fastening systems are disclosed in U.S. Patents 3,848,594, 4,662,875, 4,846,815, 4,894,060, 4,946,527, 5,151,092, and 5,221,274. Exemplary interlocking fastening systems are disclosed in U.S. Patent 6,432,098. Fastening systems may also provide components for maintaining articles in a processing configuration, as disclosed in U.S. Patent 4,963,140. Fastening systems may also include primary and secondary fastening systems, as disclosed in U.S. Patent 4,699,622. As disclosed in U.S. Patents 5,242,436, 5,499,978, 5,507,736, and 5,591,152, fastening systems may be configured to reduce movement of overlapping portions or improve fit.
[0121] Same or substantially the same basic structure As disclosed in U.S. Publication 2013-0211355, it may be desirable to provide a series of packages for fitting wearers of different sizes, but the series of packages includes the same or substantially the same basic structure. For example, the series may include a first package and a second package, the first package including an absorbent article of a first size, and the second package including an absorbent article of a second size, wherein the first package and the second package include the same or substantially the same basic structure as described in U.S. Publication 2013-0211355. More specifically, the first package may include a first base structure, and the second package may include a second base structure, wherein the first base structure and the second base structure each include one or more of the following of the same dimensions: core width at the lateral centerline, core width at one of the front core end or the rear core end, distance from the distal edge of the left outer hoop to the distal edge of the right outer hoop, distance from the distal edge of the left inner hoop to the distal edge of the left outer hoop, distance from the proximal edge of the left inner hoop to the proximal edge of the right inner hoop, distance from the proximal edge of the left inner hoop to the distal edge of the left outer hoop, free height of the inner hoop, fold width of the inner hoop pleats, length of the inner hoop elastic member, length of the outer hoop elastic member, core length, and base plate width.
[0122] Additionally, each of the first and second base structures may include one or more of the following with the same chemical composition: top sheet, bottom sheet film, bottom sheet nonwoven fabric, core superabsorbent polymer, core pulp, core nonwoven fabric, core tissue, leg band film, leg band nonwoven fabric, superabsorbent polymer adhesive, core nonwoven fabric adhesive, leg band elastic adhesive, and bottom sheet nonwoven fabric / film adhesive.
[0123] Furthermore, each of the first and second base structures comprises one or more of the following with the same basis weight: top sheet, bottom sheet film, bottom sheet nonwoven fabric, core superabsorbent polymer, core pulp, leg cuff nonwoven fabric, leg cuff film, superabsorbent polymer adhesive, leg cuff adhesive, and bottom sheet nonwoven fabric / film adhesive. Furthermore, each of the first and second base structures may contain a core superabsorbent polymer with the same composition. The first and second base structures may have the same component cross-sectional sequence and arrangement in at least one of the front waist area, rear waist area, and crotch area. The inner leg cuffs of the first and second base structures may be made of the same material.
[0124] Furthermore, the core adhesive of the first and second base structures can be one or more of the same adhesives. The first and second base structures can contain core superabsorbent polymers of the same chemical class and subclass.
[0125] Furthermore, each of the first and second base structures may respectively include a first wetting indicator and a second wetting indicator, wherein the first wetting indicator and the second wetting indicator are identical in composition.
[0126] Furthermore, the inner leg hoops of the first and second base structures may have the same component cross-sectional sequence and arrangement in at least one of the front waist area, rear waist area, and crotch area. The distance from the distal edge of the left outer hoop to the distal edge of the right outer hoop may be the same. The distance from the proximal edge of the left inner hoop to the distal edge of the left outer hoop may be the same. The distance from the proximal edge of the left inner hoop to the proximal edge of the right inner hoop may be the same. The inner and outer hoops have the same length.
[0127] In some implementations, the different sizes provided in the series may have the same or substantially the same basic structure, as flaps or straps can be used to allow the absorbent articles to fit wearers of different sizes. For example, the first and second absorbent articles may have the same basic structure (composition, dimensions, cross-section), but the first article may have different lengths due to the arrangement of the straps, such that the first article can be scaled to fit smaller wearers compared to the second article. As a second example, the first and second absorbent articles may have the same basic structure (composition, dimensions, cross-section), but the first article may have different lengths and / or widths due to the size of the straps, such that the first article can be scaled to fit smaller wearers compared to the second article.
[0128] In some embodiments, the first absorbent article and the second absorbent article may have the same basic structure in composition, but not in scale, and not in cross-section. In other embodiments, the first absorbent article and the second absorbent article may have two but not three of the following: (1) identical basic structure in composition; (2) identical basic structure in scale; and (3) identical basic structure in cross-section.
[0129] Test methods Product Measurement Preparation All measurements were performed at 22°C + / - 2° and 50% RH + / - 20%.
[0130] Purpose This method is used to prepare trouser products for subsequent dimensional measurements. It provides a consistent method for opening products removed from their bags. The method is applicable to all types of trouser products. A tensile testing machine with a constant elongation rate and a computer interface is used.
[0131] Select a load cell with a capacity that ensures an accuracy of within 0.1N for a 5N load.
[0132] Sample holder device Each of the "C" (304) and "O" (305) attachments has a rod radius of 9.50 mm, the rod radius extending beyond the length of the longest side joint. (Reference) Figure 20 The strips are mounted horizontally in the tension tester, with their longitudinal axes in the same vertical plane, and the upper strip is mounted directly above the lower strip.
[0133] Equipment assembly Calibrate the tension tester equipment according to the instrument manufacturer's recommendations.
[0134] The initial gauge length is determined as follows: 10 sample products are taken out of the bag, the trouser products 307 are unfolded, and they are arranged as follows. Figure 21 The pants are laid flat as shown, and the distance between the sides is measured at waist 306 as shown. The average of the waist measurements will be used as the initial gauge length for the specific sample group. The initial gauge length is the distance from the top edge of the upper strip to the bottom edge of the lower strip.
[0135] like Figure 22 The entire product 307 is applied to the strip as shown, while minimizing manipulation of the sample.
[0136] Pull the sample to a force of 5N and hold for 10 seconds. Return it to the initial gauge length.
[0137] Chuck speed = 254.0 mm / min, data acquisition rate = 50 Hz.
[0138] Cycle number = 1 Remove the sample from the strip, minimizing manipulation in the process. Place the sample flat with the front side facing up, as shown. Figure 6 As shown.
[0139] Repeat the procedure for all 10 samples.
[0140] Physical measurement Each of the following measurements will be performed on 10 independent similar samples, and the average of the 10 independent similar samples will be considered as the measurement of the specific sample group.
[0141] Relaxed product length 300 "Relaxed Product Length" is the longitudinal distance between the furthest point in the crotch area and the furthest point along the front waistline. This longitudinal distance is measured parallel to the product's longitudinal axis. (Reference) Figure 6 .
[0142] Relaxing product hip width 301 "Loose product hip width" is the lateral distance from the furthest point on the left side of the product at the top edge of the left leg opening to the furthest point on the right side of the product at the top edge of the right leg opening. (Reference) Figure 6 Lateral distance is measured perpendicular to the longitudinal axis of the product.
[0143] Loosening product waist width 302 "Loose product waist width" is the lateral distance from the farthest point on the right side of the front waistline to the farthest point on the left side of the front waistline. This lateral distance is measured perpendicular to the product's longitudinal axis. (Reference) Figure 6 .
[0144] The side length of the relaxed product is 303. "Relaxed Product Side Length" is the straight-line distance from the intersection of the waistline and side edge of the product to the intersection of the top of the leg opening and the same side edge of the product. The relaxed product side length measurement is the average of measurements taken from the left and right sides of the product. (Reference) Figure 6 .
[0145] Record each of the above measurements, accurate to + / - 1.0 mm.
