AND A SECONDARY HOLDING SYSTEM
FIELD OF THE INVENTION
The present disclosure generally relates to absorbent articles intended for personal use, and more particularly to disposable absorbent articles having a primary clamping system and a secondary clamping system for selectively clamping and re-clamping the article around the carrier.
BACKGROUND OF THE INVENTION
Many absorbent items intended for personal use, such as diapers, training pants, feminine hygiene products, adult incontinence products, bandages, medical garments, and the like are designed to be absorbent enough to absorb moisture from body exudates. liquids including urine, menstruation, blood, etc., away from the carrier to reduce skin irritation caused by prolonged exposure to moisture. Diapers, as an example, are typically placed and secured on a carrier through the use of a set of primary fastening tabs, such as adhesive tabs or mechanical fastening system tabs (eg, hook or loop), and left in its place to absorb aggressions as well as to contain fecal waste.

For items where the link is reusable ^ .....
such as diapers and some training pants, openings can sometimes occur suddenly (detachment of bras) as a result of the effort exerted on the coupling by movement of the wearer. For example, and particularly for absorbent articles employing only a restraint system, when a child or other carrier of the absorbent article moves (eg, crawls, walks, runs, bends, etc.) the shear stress exerted on the The restraint system due to the movement of the child can cause the restraint tabs or the like to loosen or even loosen completely, resulting in an absorbent article that tends to leak, loosen, or fall off a carrier.
Accordingly, some known absorbent articles comprise more than one fastening system and / or fasteners to reduce the likelihood that the article will leak, come loose, or fall off the wearer, etc. For example, Figure 1 illustrates a known diaper, generally indicated at 10, comprising two fastening systems: a primary fastening system and a secondary fastening system. Figure 1 depicts the diaper 10 in a flat and unfolded condition to show an outer covering 32 of the diaper that faces in the opposite direction to a wearer when the diaper is used. Diaper 10 has a direction
IMPI instituto aiaucANo M LA INDUSTRIAL REOMEDAD longitudinal 12 and a lateral direction 14. _
In the longitudinal direction 12, the diaper 10 defines a front portion 16, a rear portion 18, and a portion of the crotch 2 0 that extends between and connects the front portion and the rear portion. Diaper 10 further includes a body-facing liner 30 (facing away from the view depicted in Figure 1), and an absorbent core 34 located between the body-facing liner and outer liner 32. The diaper 10 has opposite longitudinal side edges 28 extending between a trailing edge of the waist 38 and a leading edge of the waist 40. The diaper 10 further includes a pair of longitudinally extending leg cuffs 36. The cuffs Leg 36 can be adapted to fit around a wearer's legs during use and serves as a mechanical barrier to the lateral flow of body exudates.
The rear portion 18 of the diaper 10 includes a pair of rear ears, generally indicated by the number 22. Each ear 22 includes a first primary fastening component 24 as part of the primary fastening system used to secure the diaper 10 around the waist of a carrier. The primary clamping system also comprises a second primary clamping component 76 to selectively receive and clamp the first clamping components.

Primary restraints 24. For example, the diaper 10 can be selectively moved from an unconstrained configuration (as seen in Figure 1) to a restrained or worn configuration by joining the posterior waist region 18 (and more specifically the rear ears 22) to the front waist region 16 to define a three-dimensional diaper wear configuration having a waist opening 50 and a pair of leg openings 52 (Figures 2 and 3). More particularly, the diaper 10 can be selectively moved from the configuration not subject to the use configuration by attaching the first primary fastening components 24 to the second primary fastening components 76 as is well known in the art.
The diaper 10 further includes a secondary fastening system comprising the first secondary fastening components 26 and the second secondary fastening components 78. For example, the illustrated diaper 10 comprises a pair of first secondary fastening components 26 as part of the portion diaper front 16, with a second secondary fastening component 78 provided on each rear ear 22. In such configurations, when the diaper 10 is moved to the use configuration, the first secondary fastening components 26 engage the rear portion 18 of the diaper (and more particularly, the second fastening components

provided on the rear ears 2-24 ^ - "aae-3? a --- that" "= both the primary fastening system and the secondary fastening system secure the diaper around the waist of a wearer.
However, providing the first secondary fastening components 26 in the diaper 10 can be inconvenient when the diaper is finally used. For example, a stiffness or similar properties of the first secondary fastening components 26 can lead to discomfort or decreased mobility for a diaper wearer 10. For example, when the diaper 10 is used, a child may crawl, walk, run, bend, etc., such that the front portion 16 of the diaper moves, folds, or otherwise deforms. Therefore, if the secondary fastening system (and more particularly the first secondary fastening components 26 arranged on the front portion 16 of the diaper 10) is very rigid, the user can decrease mobility since the front portion of the diaper may not Immediately deform as if the secondary fastening system were omitted from the diaper. Furthermore, a relatively stiff secondary restraint system can be uncomfortable for a wearer with the first relatively non-flexible secondary restraint components 26 that provide irritation when the wearer moves.
<img file="MX356248B_D0014.tif" />
On the other hand, the positioning of secondary fastening components 26 may further lead to discomfort for a diaper wearer 10. As seen in Figure 3, for example, the first secondary fastening components 26 may contact the skin of the carrier during the use of the diaper 10 if they are not properly positioned in the front portion 16 of the diaper. Contact with the skin by the first secondary fastening components 26, which are often hook fasteners, can cause red marks and other skin irritations. More specifically, when using the diaper 10, as seen in Figures 2 and 3, the side sides of the front portion 16 of the diaper are often shirred or otherwise compressed adjacent to the leg openings 52. When this occurs and as illustrated in Figure 3, the first secondary fastening components 26 may come into direct contact with the skin of the wearer, which in the illustrated diaper 10 the wearer is an infant or an older infant. As the wearer moves his legs, the first secondary fastening components 26 will rub against the leg causing skin irritation or red marks.
There is a need, therefore, for an improved fastening system provided in an absorbent article that provides greater protection against leaks and a bond.

When the diaper 110 is moved to the use configuration with the primary fastening components 124, 176 coupling together, the secondary fastening components 126, 178 can also be coupled together to provide increased stability and leak protection (Figures 6- and 7). For example, because the article 170 restraint system comprises four attachment points, the diaper 110 will be less prone to openings suddenly when in use. Furthermore, because the secondary fastening components 126, 178 mate with each other closer to one side of a carrier than a coupling point of the primary fastening components 124, 176, the secondary fastening system secures the diaper 110 more close to the sides and

Furthermore, as a result of the strip 180 having arched upper and lower edges 182, 184, the first secondary fastening components 126 are located in a separate relationship from the respective leg opening 174 when the diaper 110 is worn by the wearer. As a result, the first secondary fastening components 126 do not rub against or otherwise contact the wearer's skin during use. Consequently, the first secondary fastening components 126 of the present disclosure are less likely to cause irritation of the wearer's skin or red marks.
Proper placement of the first secondary fastening components 126 relative to other diaper components 110 to achieve one or more of the benefits described can be more easily understood with reference again to Figure 8. For example, L1 indicates a distance from the outer edge 128 of the diaper 110 from the center line 198 that is coaxially aligned with the longitudinal axis of the diaper 110; L2 indicates a distance from an inner edge of one of the first secondary fastening components 126 from the center line; and L3 indicates a distance from an outer edge of the first secondary fastening component 126 to the outer edge of the diaper. Therefore, the width (measured in the lateral direction 114 of the diaper 110) of the first component

In some embodiments, a ratio of L2: L1, L2: L3, and / or L1: L3 can be appropriately configured such that diaper 110 exhibits one or more benefits described in the present disclosure. For example, in some embodiments, the diaper can be constructed such that the ratio of L2: L1 (i.e., the ratio of a distance from centerline 198 to an inner edge of the first secondary fastener component 126 compared to a distance from the center line to the outer edge 128 of the front portion 116 of the diaper 110) is at least 0.50 and is less than 1.00.

Gurley stiffness test
A Gurley stiffness test is commonly used to determine the stiffness of a test specimen (such as, for example, the first component of its secondary stem 126) with respect to a bending moment produced by a force directed perpendicular to the plane substantially defined by the length and width of the specimen being tested. A description of a Gurley stiffness test is set out in TAPPI Standard Test T543 om-94 (resistance to paper bending (Gurley type tester). A suitable test apparatus for conducting the Gurley stiffness test is a digital stiffness tester. Gurley, model 31644 manufactured by

For the purposes of this description, the Gurley stiffness values mentioned are those that would be generated by a standard size sample (i.e., 1 inch wide by 3.5 inches (88.9mm) long) by using the Gurley digital stiffness. Accordingly, the tester readings are appropriately converted to the stiffness of a standard-size sample (i.e. 1 inch (25.4mm) wide by 3.5 inches (88.9mm) long), and are reported in terms of milligrams ( mg) of force.
Generally, the Gurley Digital Stiffness Tester consists of a pendulum with grooves to fit various weights. The specimen being tested presses the pendulum to the right and left resulting in two readings. The readings are positively correlated with the stiffness of a specimen. The two readings are then averaged and multiplied by a factor. This factor is determined by the size of the specimen, the distance from the · central pivot, and the weight used on the pendulum. The Gurley stiffness test methodology is set out below.
For the purposes of this description, test specimens are prepared, for example, taken from a larger sample or product, by cutting the
Τ
I
MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY specimen to have its length in the direction of the machine or longitudinal of the product. As an example, for the present disclosure where the first secondary fastening components (eg hook fasteners) are tested, the specimens are cut from the diaper to include the fastener along with the material to which it is attached, for example the liner outside of the diaper. Each specimen should be cut 12 mm wide by 2.5 mm long + 1 mm (or 0.5 inch by 1 inch ± 0.04 inch).
To conduct the Gurley Stiffness Test using the Gurley Digital Stiffness Tester, the base of the instrument is first leveled by adjusting the leveling screw until the bubble levels are centered and the pendulum pointer indicates zero. After turning on the power, the specimen is used to determine the proper weight and position of the weight on the pendulum to obtain a reading between 2 and 6 on the scale / display. The switches are adjusted to correspond to the weight being used, the position of the weight on the pendulum, the width of the specimen being tested, and the length of the specimen.
For each specimen, the specimen strip is centered over the pendulum so that 6.4 mm ± 1 mm (or 0.25 inch ± 0.04 inch) overlap the top of the pendulum and 6.4 mm + 1 mm (or 0.25 inch ± 0.04 inch) is held in the tester clamps. The system reboots from

^ Se ^ 'Tíác'é operate the motor direction switch to engage the clamp arm to press the specimen against the pendulum. Both a left reading and a right reading are taken, and an average reading is determined. The SELECT button on the tester is then pressed to obtain the stiffness calculation (in milligrams) and the stiffness is recorded. The steps mentioned above are repeated for each test specimen in the sample group.
Example
The first secondary fastening components of two different absorbent products were subjected to the Gurley stiffness test to assess the relative Gurley stiffness of each. The first product was the KC-Mexico diaper, which has fastening components that are hook fasteners and that are made of polypropylene. Each specimen had the following test conditions: weight 25g, and weight position 4 (101.6mm); and measurements: width 0.5 (12.7mm), and length 1 (25.4mm). The second product was made in accordance with the present description with the fastening components which are hook fasteners and which are made of polyethylene. Each specimen had the following test conditions: weight 25g, and weight position 2 (50.8mm); and measurements: width 0.5 (12.7mm), and length l (25.4mm). Ten specimens of each product were tested.

Edge stiffness test
An edge stiffness test determines the edge stiffness of a test specimen 500 (such as, for example, the first secondary clamp component 126), and more particularly measures the amount of force, in grams (grams-force, or gf), required to bend or fold by applying a longitudinal force against an edge of the specimen. This is indicative, for example, of the way in which a force should be applied by a wearer to the first secondary fastening components 126 of the diaper 110 when the wearer bends at the waist.
Returning now to Figure 16, a rectangular (elongated) specimen 500 is held vertically (i.e., longitudinally) by a grip, or clamps (i.e., upper clamp 516 and lower clamp 518), with the edge or end short the specimen perpendicular to and in contact with a flat surface or platen 520. The contact edge is then gradually pushed against the flat surface by moving the clamp or clamps 516, 518 toward the flat surface 520 for a recorded distance until
Hee XvA Jl 1 FNS-nTUT · MEXICANO 'áSóámsfiS r ?. the «íópt'dad r ^^ sJEj<sup>v</sup> IU7UJTÍUAL the specimen bends or folds. As can be seen from Figure 17, which is a graph of compression force versus compression distance (i.e., the distance at which the grip or clamps 516, 518 moves to the flat surface during testing) and Described in more detail later in the present disclosure, the compressive force initially increases proportionally with the compressed distance, i.e., the distance at which the grip or clamps move toward the flat surface 520. After a maximum compressive force is reached, the force decreases asymptotically towards a constant as the compressed distance increases. Edge stiffness is the maximum compressive force achieved during the test, with a lower compression force which means that specimen 500 has a lower edge stiffness, or more easily folds after the application of a force to the edge of the specimen.
A suitable test apparatus for conducting edge stiffness testing is an MTS Sintech 500S tensile frame manufactured by MTS System Corporation, a company that has offices in Eden Prairie, Minnesota. Additional instruments used to perform the edge stiffness test include a 100 Newton D86201 load cell, a top member that has a 516 top clamp that is 1 (25.4mm) long and 3 (76.2mm) long.

wide, and a steel platen ί ηηχί ....., jg! ........ Pinferior 520 which has a diameter measuring 3.5 (88.9mm) (all manufactured by MTS System Corporation). A thickness measurement device such as the Sony Digital Indicator U30A equipped with a 0.05 psi stage is also used, manufactured by Sony Corporation of America, a company that has offices in New York, New York.
To carry out the edge stiffness test for the purposes of the present description, the specimens
500 they are cut to a width of 15 mm in the lateral direction 114 of the product, such as the diaper 110 in the illustrated embodiment, and a length of 40 mm in the longitudinal direction 112 of the product. The thickness of each specimen 500 is measured using the thickness measuring device with a 0.05 psi (344.79pa) stage with an approximation of 0.001 mm. The distance between the lower plate 520 and the lower part of the upper clamp 516 is set to 10 mm and the specimen 500 is placed in the upper clamp with the specimen longitudinally oriented. The bottom edge of specimen 500 is in slight contact with the flat surface of bottom plate 520.
The upper clamp 516 is activated to move down towards the lower plate 520 at a speed of 6.35 mm / min. (0.25 inch / min.) To compress lengthwise

IMPI the specimen 500 until the force drops from, eg jKfoj-mo. V is leveled. Test data of compression force versus compression distance (for example, top clamp downward displacement distance 516) is recorded on a PC using the trade name program Tesdosrks V4.12C provided by MTS System Corporation. The compression force is reported with an approximation of 0.1 grams-force (gf). The maximum compression load (in gf) for each specimen 500 tested is determined by using this program. The maximum compression stress in gf / mm<sup>2</sup> is calculated by dividing the maximum compression load in gf by the cross-sectional area in mm<sup>2</sup>.
Example
The first secondary fastening components of two different absorbent products were subjected to the edge stiffness test to assess the relative edge stiffness of each. The first product was the KC-Mexico diaper which has hook fasteners made of polypropylene. The second product was a diaper 110 made in accordance with the present disclosure with the first secondary fastening components 126 which are hook fasteners and which are made of polyethylene.

Figure 17 is a 'compression vs. compression distance' force graph for KC-Mexico diaper specimen # 5 (trend line A) and product specimen # 5 of the present description (line trend B) of the stiffness test of the anterior border. Each curve shows the amount of force required to fold or bend the specimen by applying force to the edge of the specimen. For example, trend line B indicates that the compression force required to fold or bend the specimen of a product made in accordance with the present description was increased until the specimen was doubled to a maximum compression force of 40.6 grams-force. (after only a slight amount of compression distance). After the maximum compression load, the compression force required to further bend the specimen 500 is asymptotically decreased to approximately 20 gram-force.
Trend line A indicates that the compression force required to fold or fold the KC-Mexico diaper specimen 500 was increased until the specimen was doubled to a maximum compression force of 110.7 grams force. After the maximum compression load, the compression force required to further bend the specimen 500 is asymptotically decreased to approximately 80 grams of force. Consequently, more force is required to compress the edge of a specimen 500 of the KC-Mexico iMPiféra diaper.

Therefore, it can be concluded that the edge stiffness of the first secondary fastening component 126 of the product of the present description was less stiff than that of the KC-Mexico diaper.
Accordingly, in one embodiment the first secondary fastener component 126, and more particularly the secondary hook fastener on the front portion 116 of the diaper 110 as in the illustrated embodiment, has an edge stiffness in accordance with the edge stiffness test. less than 100 grams-force, more adequately less than 90 grams-force, even more adequately less than 80 grams-force, even more adequately less than 70 grams force, and even more adequately less than 60 grams-force. In other modalities it is less than 50 grams-force.

In other modalities, the edge stiffness and / or the average edge stiffness of the first secondary fastening component 126 may be even less than the ranges stated above and remain within the scope of the description.
Referring to Tables 3 and 4, the KC-Mexico 500 diaper specimens had an average maximum load of 126.7 grams-force while the specimens in the present description had an average maximum load of 48.9 grams-force. Another embodiment of the present disclosure has an average maximum load of less than 90 grams-force based on the sample size of at least 5 samples. Another embodiment of the present disclosure with a sample size of at least 5 samples has an average maximum load of less than 8 0 grams-force. Still another embodiment of the present disclosure with a sample size of at least 5 samples has an average maximum load of less than 70 gram-force. Still another embodiment of the present disclosure with a sample size of at least 5 samples has an average maximum load of less than 60 grams-force.
With continued reference to Tables 3 and 5, the KC-Mexico 500 diaper specimens shown in Table 3 vary from a maximum maximum load of 100.1 grams-force to a maximum maximum load of 158.2 grams strength. The specimens of the present description 500 that are

Therefore, in view of both the stiffness test of
Gurley as the edge stiffness test, as used particularly in the examples above, it is evident that the first secondary fastening components 126 are less stiff than the first secondary fastening components of the KC-Mexico diaper. As used in the diaper 110 described herein, such reduced stiffness increases wearer comfort and reduces red marks that can irritate the skin.
