Description

CLOSURE SYSTEM FOR DISPOSABLE PULL-ON PANTS HAVING A STRETCHABLE WAISTBAND} Disposable pull-on pants with elastic waistband

Disposable undergarments have been designed to address the needs of infants and children for pull-on pants for training. Also, making these disposable undergarments larger can be for adult incontinence. Conventional adult incontinence products are generally designed to be held in place by a strap or fastener that is worn in the crotch and extends from the back of the product around the wearer to the front panel and attached at a point near the end of the absorbent pad. Or pads. The prior art products are diapers which rely solely on the attachment straps for wear and maintenance.

Whether the wearer is an infant or an adult, their waistline is different; As a result, many different dimensions of garment are required for use by all individuals. It is desirable to provide a limited quantity of dimensions in the production line in consideration of the product and inventory while being acceptable for a wide range of waist dimensions of the consumer.

If the wearer's waist is slightly smaller than the pant's optimal waistline, particularly when urine or other body waste is loaded into the garment, the pants may be prone to flow out of the wearer or to create gaps in the waist to leak. The pants garment has sufficient stretch in its elasticized portion to allow the wearer to easily wear the pants. However, if the wearer's buttock has an insufficient size relative to the waist, as in the case of infants and small children, such wearer's easy wearing also holds the garment in the normal wearing position without gaps that may cause leakage. This may mean that the force generated between the buttocks of the wearer and the absorbent pants garment may be insufficient.

With respect to similar types of adult garments for incontinence, in some cases the boundaries between the waist and hips of the elderly are not sufficient to provide good support for the pants garment when used solely by the elastic forces in the side panels and the elasticity of the waistbands of disposable absorbent pants. Insufficient

Incontinences sometimes want to avoid using diapers because of their face and use a more convenient pants-type garment. In addition to absorbency and one-off in adult incontinence products, the conditions for such pants-type structures include comfort, reliability, and elegance; In addition, infants or children undergoing bowel movements require practical pants-like structures to actively reinforce their practice.

The present invention has a disposable pull-on pant with an elastic waistband, in particular an elastic waistband and pants that have a closure system such as a fastener to fit the wearer and prevent gaps or leakage from the waist. It relates to a disposable pants.

It is an object of the present invention to secure disposable absorbent pull-on pants to the wearer while taking advantage of the pull-on garment.

It is an object of the present invention to increase and supplement the elastic force necessary to secure a pull-on stretchable disposable pants product to a wearer.

A further object of the present invention is also to efficiently measure the waist dimensions of the pull-on elasticized disposable absorbent pants whenever the waist size of the pants is somewhat too large for the hips and waist of the wearer or a gap occurs in the waist of the pants. To adjust or reduce.

Absorbent disposable pants-like products, such as in US Pat. No. 5,246,433 to Hasse et al., Commonly assigned with this application, are known and are used as training pants for infants and children. As part of physical function control exercises for infants, it is desirable to provide the same general type of garments that infants will wear after fully practicing. Part of this exercise involves learning how to remove and when to remove a garment to use the toilet. This requires the infant or child to provide a garment that can be easily put on and taken off the buttocks and can be easily removed. In addition, if the garment is not contaminated, it can be reused by pulling the garment over the buttocks for continuous wear.

A training pant-type garment is designed to have a stretched or elasticized waistband and side panels so that each time the garment is pulled over the hip of the wearer, the garment can extend to a larger dimension. The force required to properly stretch the garment should not be too large, which is too large for the individual to properly remove the garment in a timely manner and thus cannot actively enhance success and reposition the garment in the proper position. . Lower elastic forces may be desirable to maximize ease of wearing, removal or general fit. Thus, the stretching force must be adjusted and in some cases may be insufficient to keep the garment in the normal wearing position.

Therefore, it is desirable to supplement the elastic waistband and side panel holding forces by adding a fastener to allow proper force to be exerted between the wearer and the garment to maintain the garment in its normal wearing position. Fasteners are generally formed as straps or strips of material that can be mounted or attached onto either the back or front panels of a pants-like garment. The fasteners can be strongly secured to the garment and can be held in a retracted or accumulated position, such as a folded position, for immediate use. Alternatively, the fasteners are fixed in front of the garment and only need to be loosened before the wearer wears the garment. After the garment is positioned to the wearer, the fastener can be pulled across the side panel and engaged with the front panel at the designated engagement zone or landing zone. Alternatively, the fasteners may extend to overlap one another when one fastener acts as the landing band of the other fastener. The fasteners can be pulled tight enough to adequately reduce the waist dimension of the pants to prevent accidental dripping of the pants over the hips of the wearer and to reduce the possibility of gaps in the waist that may cause leakage. The side panels of the cement may be corrugated if necessary.

The fasteners can be one of several different forms. The fasteners may preferably be adhesive fasteners or mechanical fasteners. In addition, the fasteners may be inelastic strips or straps or may be stretch elastic strips.

In the case of an adhesive fastener, the adhesive is a known adhesive for reusing the garment and re-gluing the fastener to the landing zone by providing high adhesion for strong adhesion or proper adhesion so that the adhesive can easily fall off of the material of the landing zone. Can be selected from.

The fasteners may alternatively be mechanical fasteners such as hook / loop fasteners, snaps or hook / hole fasteners similar to VELCRO brand fasteners.

Either a mechanical fastener or an adhesive fastener can be retained in the Z-wrinkles and then extend across the elongation panel at the side of the garment to pleat to engage the fastener with the front panel. In adhesive fasteners, the adhesive surface can be engaged in a face to face relationship with the release surface on the Z-pleat fastener and thereby be protected. Thus, the adhesive may be removed from the release surface but proper adhesion to the outer layer of the garment is still maintained each time it engages the landing zone.

In order to keep the mechanical fasteners in the Z-wrinkled unused position, a small point or area of adhesive is applied between adjacent portions of the mechanical fastener strips. Such application of adhesives extends without folding the fasteners, The fasteners will remain in their folded and unused positions until they engage the front panel.

The foregoing summary focuses primarily on infant training pants and is particularly suitable for this use, but the same principles and embodiments can be applied to larger dimension garments for adult incontinence. Regardless of the desired wearer, the pants may comprise elastic or stretchable members disposed to partially enclose the wearer's waist. Each time the fastener is stretched and pulled towards the front panel of the garment, the elastic member that partially encloses the waist will eventually extend and provide resistance to pulling the fastener toward the landing zone. Since the elastic or stretchable portion of the garment is stretched by pulling the fastener toward the landing zone, the force to resist this pulling will increase and thus provide the force needed to secure the garment to the wearer more strongly. The degree of elongation can be varied to adjust the force generated by the use of fasteners. Particularly in adult incontinence garments, the substantial holding force exerted by the fasteners around the wearer's waist gives the wearer the tactile stability that the garment is in place and the additional stability that the garment will remain stronger in the proper wearing position. Will give. This trust is very important to maintain the dignity of the incontinents.

The invention will be better understood from the accompanying drawings and the following detailed description.

First, in FIG. 1, the disposable absorbent pull-on pants type garment 20 is shown having a front panel 56, a crotch panel 57, and a back panel 58. This type of garment 20 is described more fully in the following document. See US Patent No. 5,246,433 to Hasse et al., September 21, 1993, The Procter and Gamble Company, Cincinnati, Ohio. Transferred to)]. US Pat. No. 5,246,433, which is incorporated herein by reference, discloses such a garment and a method of making the garment.

Such garments may be manufactured in a number of different dimensions and may be sold for adult incontinence as well as for infant body function practice.

The elasticized flap 30 preferably extends from the front panel 56 and the back panel 58, respectively. Any conventional and suitable technique, such as pasting, ultrasonic bonding, thermal bonding or adhesive attachment, may be used to form the seam 10 to complete the pants-shaped garment 20 as shown. An elastic waistband member 76 is incorporated into the waistband region 34 near the waist opening 19. Preferably, the elastic member 76 is interposed between the inner layer 46 and the outer layer 48 of the garment 20. The inner layer 46 and the outer layer 48 each form a frame 14 of the pants 20. Similarly, elastic panel 90 may be disposed between inner layer 46 and outer layer 48 in the region of elasticized flap 30 to provide elastic stretch. Alternatively, the elastic panel may be exposed and not included between the layers 46 and 48.

The fasteners 16 are preferably disposed on the back panel 58 of the pants 20 and overlie at least a portion of the surface of the pants 20 in the waistband region 34. Waistband region 34 is an outer layer 48 region overlying elastic member 76 and proximal to edge 18 of pants 20 at waist opening 19.

As shown in FIG. 4 at the rear, a fastener 16 comprising a strap 15 may be disposed on the front panel 56 of the pants 20 if desired, but in general a fastener 16 is It is desirable to be secured to the back panel 58 so that the fastener 16 extends forward and can be easily attached to the front panel 56 by the wearer or by a person assisting the wearer.

In Fig. 2, the structure of the mold 14 becomes more apparent. The mold 14 includes a liquid impermeable outer layer 48, an absorbent pad 24, an elastic panel 90 and an elastic member 76. The elastic panel 90 and the elastic member 76 may be closed between the impermeable outer layer 48 and the transparent inner layer 46 together with the absorbent pad 24, which is described in more detail in US Pat. No. 5,246,433. have. The mold 14 generally carries a fastener 16 arranged to rest on one of the elastic members 76. The elastic panel 90 may be exposed and connected at the edge to the flap 30 or to the edge of the panel 90. The practical purpose of an elastic panel, such as panel 90, is to provide elasticity to the waist of the pants 20.

The mold 14 can then be folded and the elasticized ears 30 can be joined together using adhesive, glue, thermal or ultrasonic bonds to form the side panel 31. Other conventional connection techniques are also advantageous.

Referring now to FIG. 3, this figure shows a pants 20 of the nature described in FIGS. 1 and 2 showing the attachment of one of the fasteners 16. The fastener 16 preferably consists of three fractions 21, 22 and 23. The fraction 21 is preferably secured to the back panel 58 of the pants 20. Fraction 21 may be secured to the back panel 58 of the pants 20 by high strength adhesives, thermal bonding, ultrasonic bonding or other desirable techniques that can be securely attached. In addition, the fastener 16 may be releasably attached to the pants 20 so that the user can remove it completely when desired. Adhesive attachment techniques are useful for manufacturability, practicality and durability in use (the fastener may be considered unattached to the pants 20 until the user attaches the fasteners 16 to the pants 20).

Fraction 22 may be folded back over fraction 21 and held in place by a small area of adhesive 25. The adhesive 25 may be a low-tack adhesive enough to keep the fraction 22 in the folded back position over the fraction 21.

Fraction 23 of fastener 16 is a small area of surface 27 used to secure and retain adhesive 25 or fraction 23 on fraction 22 on surface 27 of fraction 23. It can be kept adhesive by a small amount of the adhesive 25 defined in FIG.

In FIG. 3, the fraction 23, in particular the surface 27, is coated with an adhesive, so that the fasteners 16 are stretched by pulling the fraction 23 and its adhesive coating 35 out of the fraction 22 to form a seam 10. The surface 27 of the fraction 23 carrying the adhesive layer 35 can extend beyond the position to engage the front panel 56. The fasteners 16 can be pulled to extend the elastic member 76 shown in FIGS. 1 and 2 to create a force that can effectively reduce the perimeter of the waistband 34 of the pants 20. When the fastener 16 is pulled and engaged with the front panel 56, the side panel 31 and the elastic ear 30 are wrinkled or folded, so that the circumference of the waistband 34 is effectively reduced.

4 is shown to be positioned to engage the fraction 21, the extended intermediate fraction 22, and the front panel 56 of the pants 20 that are strongly attached to the back panel 58 of the pants 20. A fastener 16 including fraction 23 is shown.

5 shows the fully extended and engaged portion so that the fraction 22 extends across the resilient ear 30 and the side panel 31 and the fraction 23 adheres to the outer layer 48 in the overall area of the elastic member 76. Further shown is fastener 16 in a state of engagement with a castle. Accordingly, the engagement region pulls the fastener 16 to make it fit and engages the outer layer 48 of the pants 20 in the landing zone 33 in the region of the elastic member 76, thereby releasing the fastener 16 thereby. Forms a landing zone 33 for fraction 23 of (16); The restoring action of the member 76 reduces the circumference of the waist opening 19 of the pants 20 so as to be in close contact with the waist of the wearer.

In FIG. 6, disposable pants 20 are shown in a partially cut form that includes another embodiment of fasteners 16. Fractions 21 and 22 are as mentioned above in connection with FIGS. 3, 4 and 5, while fraction 23 has a plurality of hook members 28 on its surface 27. The hook member 28 can be manufactured by placing it on the fraction 23 according to the teachings of the following document. See US Pat. No. 5,116,563 to Dennis A. Thomas et al., May 26, 1992 ("PROCESS FOR"). PRODUCING A MECHANICAL FASTENER "); U.S. Patent No. 5,180,534 to Thomas et al. On January 19, 1993 ("PROCESS OF MANUFACTURING A REFASTENABLE MECHANICAL FASTENING SYSTEM"); And US Patent 5,230,851 issued to Thomas on July 27, 1993 ("PROCESS OF MANUFACTURING A REFASTENABLE FASTENING SYSTEM"). Each of these patents is incorporated herein by reference.

The hook member 28 passes through at least a portion of the front panel 56 that forms the landing zone 33 of the pants 20, in particular through a hole 29 formed through the outer layer 48 to penetrate the hole. Can be. When the fastener 16 is released after the hook 28 is locked into the hole 29, as shown in FIGS. 1 and 2, the elastic force of the elastic member 76 is contracted so that the hook 28 is closed by the hole 29. To draw from. As already described with reference to FIGS. 1 and 2, the hook 28 that engages the outer layer 48 will generally retain the hook 28 and fraction 23 in a position that rests on the elastic member 76. Those skilled in the art will appreciate that the portion where the fastener 16, hook 28 and hole 29 meet may be reversed.

Another embodiment of a fastener is shown and described in FIG. 7, which is now intended to be mentioned.

Fastener 16 in FIG. 7 is substantially the same as fastener 16 in FIG. 6. Fraction 23 of fastener 16 includes a plurality of hook members 28 over one surface 27 thereof.

The front panel 56 of the pants 20, in particular the outer layer 48, supports the backing sheet 36 and the plurality of loops 37 (although the outer layer 48 of the pants 20 has a number of loops 37. It can be formed from a material containing). As used herein, the term "multiple loops" refers to any looped fastener component capable of engaging complementary hook parts. Some non-limiting examples of loops suitable for use in the present invention include loops formed by coupling loops to a backing; Loops formed by corrugating or making fibers; And the loops disclosed in the following references incorporated by reference to US Patent Application No. 07 / 703,441, filed by David Goulait on May 20, 1991, and Noel et al. On July 16, 1991. U.S. Patent No. 5,032,122 ("LOOP FASTENING MATERIAL FOR FASTENING DEVICE AND METHOD OF MAKING SAME") [Many loops 37 are replaced with hook members 28, so that fasteners 16 replace hook members 28. It is also to be understood that multiple loops 37 can be engaged with complementary hooks located where they are located.

The backing sheet 36 is preferably glued or glued to the outer layer 48 at a desired position, which position is substantially the same as the position described for the hole 29, and the backing sheet 36 is attached to the backing sheet 36. Support a number of loops 37. Once the fasteners 16 are extended and pulled forward to fit the waist of the pants 20 and squeezed into engagement with the plurality of loops 37, the plurality of loops 37 are engaged by the hooks 28. If the pants 20 are worn by the wearer and the fasteners 16 are extended so that the hooks 28 engage the multiple loops 37 and attempt to remove the pants 20, the hooks 28 may be lifted by pulling the fractions 23. ) Can be released from a number of loops 37, so that the force exerted on the pants 20 by the fasteners 16 can be alleviated and the pants 20 can be peeled off on the wearer's buttocks. If the pants 20 are uncontaminated, they are again worn by the wearer so that the fasteners 16 are extended again and the hooks 28 engage the multiple loops 37 to the wearer to hold the pants 20 in place. Increase the force exerted. The fasteners may be elastic straps or inelastic straps.

Another embodiment of a fastener 16 that may be included in the pants 20 is shown partially cut in FIG. 8.

Fragments of the back panel 58 and front panel 56 of the pants 20 as shown in FIG. 1 are shown with the fraction 21 strongly attached to the back panel 58. Fraction 22 and Fraction 23 of the fastener are partially extended. Above the fraction 23 a portion of a snap fastener consisting of a post 73 and a gland fastener 70 is formed. In the illustrated embodiment of FIG. 8, the grommet 70 may be attached to the fraction 23 by adhesive, glue or thermal bonding. The gutter 70 is preferably a plastic ring having a central opening 72. The grommet 70 may engage the second element of the fastener 16, which is in the form of a post 73 supported on the reinforcing disk 74. The post 73 has a bulb-shaped head 75 of constant diameter. The head 75 of the post 73 can fit into the central opening 72 of the sash 70 and the slack 70 and the head 75 until the head 75 passes through the central opening 72. ) Can be pushed toward each other.

The easily yielding nature of the plastic is advantageously used to form the rim 70, post 73, head 75 and support disk 74. In order to release the fastener 16 from the front panel 56, the fraction 23 of the fastener 16 is generally pulled outwards to remove the head 75 from the central opening 72 of the sash 70 by disposable The glove 70 may be separated from the front panel 56 of the pants 20.

To accommodate the various waist dimensions of the wearer, the fraction 23 is provided with a number of paddles 70 while the front panel 56 is provided with a number of posts 73 and heads 75 of the fasteners 16. Can be. In addition to allowing any grommet 70 to engage any head 75 and post 73, the distance between the grommet 70 and the distance between the posts 73 may vary such that a wide waistline may be present. 16) to be accommodated. In addition, the clasp 70 and the post 73 can be formed on separate fastener straps 13 and can therefore be engaged. The fastener straps 13 can effectively reduce the size of the waistband 34 of the pants 20 without forming a grommet or post 73 on the front panel 56 of the pants 20.

By adjusting the number of gaskets 70 and the number of posts 73, a considerable number of types of waist dimensions can be accommodated by the fasteners 16 by the number of engagements in the engaged position. For example, for each fastener 16 having three claws 70 and three posts 73, nine possible positional combinations may be made. If there are two such fasteners 16 (there are different fasteners on each side of the pants 20 as shown in FIG. 1), it is possible to produce 81 different waist dimensions over a relatively wide range. . Thus, a garment that may be slightly larger for a particular wearer is an adhesive fastener as shown and described in FIG. 1, a hook 28 / hole 29 fastener 16 as shown and described in FIG. 6, or a figure. Using the hook 29 / multiple loop 37 fasteners 16 of 7, it can be adjusted to accommodate wearers with different waist dimensions corresponding to as many positions as possible.

Although the present invention has been described primarily with respect to the attachment fraction 21 of the fastener 16 attached to the back panel 58 of the pants 20, the fastener 16 may also be attached to the front panel 56 in a similar manner. It must be understood. Attachment of the front panel 56 may include holes 29, multiple loops 37, landing bands 33 of the posts 73 or head 75, or adhesive fasteners to the outer layer 48 of the rear panel 58. It requires an adhesively engageable open area 33 to be engaged. In addition, a hole 29 shown in FIG. 6 extending through the outer layer 48 can be formed in the fraction 23 of the fastener 16 and the hook 28 is on the outer layer 48 or another fastener 16. It is to be understood that the phase can be located with the same performance. Similarly, the backing sheet 36 with the hook 28 and the plurality of loops 37 may be interchanged with each other in the position shown in FIG. 7 as the case may be, or the post 73 and the sash (FIG. 70). The grommet 70 and post 73 and head 75 may similarly be interchanged from the position shown in FIG. 8 without loss of performance.

In any embodiment of the fasteners 13, 16 shown in any of the figures, the purpose is to pull the fasteners 13, 16 to fit and to efficiently measure the waist opening 19 dimensions of the elasticized disposable pants 20. Elastic pants 20 so that the wearer can pull the pants 20 over the hips to wear them in the normal wearing position and keep the pants 20 in the normal wearing position until the pants 20 are removed from the wearer. To replenish its elasticity. Although some embodiments of the fasteners 16 have been applied to the elasticized disposable absorbent pants 20, the fasteners 16 type, for the front panel 56 and the back panel 58 of the pants 20. Minor changes to the location of the fastener 16 and the technique of attaching the fastener 16 to the pants 20 can be made further, and also to the portions and portions of the pants where the fasteners are disposed without departing from the scope of the present invention. It should be understood that this part may change or be reversed.

Another preferred embodiment of the present invention is shown in FIGS. 10 and 11. As can be seen in FIGS. 10 and 11, the pants 20 generally have a longitudinal centerline 100 that bisects the pants 20 into right and left halves when worn. The pants also have a lateral centerline 102 that bisects the pants 20 generally into a front half and a back half when the pants 20 are worn.

The pants 20 are frame 14 having a front panel 56, a back panel 58, a crotch panel 57 between the front panel 56 and the back panel 58 and a pair of longitudinal edges 150. It includes. The front panel 56 and the back panel 58 each preferably include a waist edge 104 that forms at least a portion of the waist frame 110 of the pants when the pants 20 are fitted to the wearer.

The front panel 56 preferably includes a pair of opposing first side panel flaps 112. The first side panel flap 112 is preferably elasticized or elastically extended and extends laterally outwardly from the opposite side of the front panel 56 of the frame [the term “elastically extended” is a force When applied, it refers to a substance that extends in at least one direction and returns to its original dimensions after the force is removed. The term "laterally outward" means herein the direction generally away from the longitudinal centerline 100 of the pants 20. The back panel 58 preferably includes a pair of opposed second side panel flaps 114. The second side panel flap 114 may preferably extend resiliently and extend laterally outward from the opposing face of the back panel 58 of the frame 14.

The first side panel flap 112 and the second side panel flap 114 each include a proximal edge 116 and a distal edge 118 disposed laterally outward. Further, the first side panel flap 112 and the second side panel flap 114 include a first end edge 120 and a second end edge 122, respectively. The second distal edge 122 is preferably disposed longitudinally inward of the first distal edge 120 (the term "inward longitudinally" as used herein refers to the lateral centerline 102 of the pants 20). ] Is the direction of the direction.

In a preferred embodiment, the distal edge 118 of one of the first side panel flaps 112 is connected with the distal edge 118 of one of the second side panel flaps 114 and the first side panel flap 112. The distal edge 118 of the other of which is connected with the distal edge 118 of the other of the second side panel flaps 114 to form the pants 20. Distal edge 118 may be connected by any means known in the art. A detailed discussion of how to connect the first panel flap and the second panel flap can be found in U. S. Patent No. 5,246, 433 to Hasse et al., Commonly assigned with the present application. However, this description should not be construed as limiting the scope of the invention to embodiments in which only the distal end is connected.In fact, for ease of manufacture and other purposes, the first panel flap and the second It is also contemplated that a portion of the member to be connected in parallel to the distal edge may be connected with or instead of the distal edge, as long as the panel flaps are joined together to form the pants).

One unique feature of the other embodiments shown in FIGS. 10 and 11 is that the first end edge of the second side panel flap 114, to which one or more first side panel flaps 112 are connected, is connected. It has a first distal edge 120 disposed in the longitudinal direction of 120. In this configuration, as shown in FIG. 11, when the pants 20 are fitted snugly to the wearer, the first end edge 120 of the first side panel flap 112 is the waistline 110 of the pants 20. It is disposed inward in the longitudinal direction from the remaining structure forming the. The first distal edge 120 of the first side panel flap 112 may be located anywhere in the longitudinal direction of the first distal edge 120 of the second side panel flap 114 (as can be seen in FIG. 11). One particularly preferred embodiment of the pants 20 has a first distal edge 120 of the first side panel flap 112 located between the upper and lower edges of the belt flap 125, which will be described in detail below.

As can be seen in FIG. 12, another preferred embodiment of the present invention has a pair of side panel flaps 112 and 114 that are connected [one first side panel flap 112 is one second side panel flap 114. ), Wherein the first distal edge 120 of each of the individual side panels that make up the connected pair is disposed longitudinally inward of the waist edge 104. In a particularly preferred configuration of this embodiment, the side panel flap 112 and the first distal edge 120 of the side panel flap 114 are located between the upper and lower edges of the belt flap 125.

The pants 20 preferably further comprise one or more belt flaps 125 extending laterally outward from one or more longitudinal edges 150 of the one or more first or second side panel flaps or frameworks 14. do. In one preferred embodiment shown in FIGS. 10 and 11, the belt flap 125 extends laterally outward from each second side panel flap 114 parallel to the first distal edge 120. In another preferred embodiment as shown in FIG. 12, the belt flap 125 extends laterally outward from the longitudinal edge 150 of the frame 14 in the back panel 58 of the pants 20. In certain embodiments, belt flap 125 has an upper edge 127 and a lower edge 129. The lower edge 129 is preferably disposed longitudinally inward of the upper distal edge 127. In addition, the upper distal edge 127 preferably forms at least a portion of the waistline 110 of the pants 20 when the pants 20 are worn to fit the wearer.

Belt flap 125 may comprise any suitable material or materials known in the art. Belt flap 125 may also be formed from a portion of another element of the pant (eg, topsheet, backsheet or side panel flap) or may be individually connected to pant 20 by any known method for connecting such materials. It can be an element. In a preferred embodiment, the belt flap 125 can be elasticized or elastically extended to provide tension when used to efficiently reduce the dimensions of the waistline 110.
