BACKGROUND OF THE INVENTION
While disposable absorbent garments offer a comfortable way to manage bedwetting, many enuretic families are not satisfied with these products because they are seen as a diaper type by the user who wants to wear conventional underwear. As such, many improvements are made to disposable absorbent garments to make them more similar to underwear. For example, gender specific graphics are added and softer nonwoven materials are used. However, many potential users are still looking for a product that looks and feels more similar to conventional underwear, but is nonetheless able to help control bedwetting. Therefore, there is a need for a brief that is similar to underwear but helps contain urine output.

In general, any of the containment fins described herein may further include one or more elastics of the containment fin.
The containment fin elastics can be joined to the containment fins in any suitable configuration by use of any suitable bonding means. For example, in some embodiments, the containment fin elastics can be joined to the containment fins by using mechanical fit, adhesive bonding, thermal bonding, ultrasonic bonding, pressure bonding, sewing, or the like, or combinations of these.
In some embodiments, the containment flap elastics can be at least partially enclosed within a channel formed by folding a portion of the containment flap. For example, Figure 14 representatively illustrates a cross-sectional view of sling 52 of Figure 13 taken along line AA.

The elastic of the containment flap 70 is enclosed within channel 71 and may partially join the flap of containment 54. In other embodiments, the elastic of the containment flap may be disposed within the channel but not be attached to the containment flap.
In some embodiments, the elastic of the containment flap can be folded over the distal edge of the containment flap. For example, Figure 20 representatively illustrates a cross-sectional view of sling 102 of Figure 19 taken along line BB. In this embodiment, proximal portion 112 of containment flaps 104 and 105 are attached to base sheet 106 to form containment seals 116. The elastics of the containment fin 120 are bent over the distal edge 121 of the first lateral containment fin 104 and the second lateral containment fin 105. The elastics of the containment fin 120 can be joined with the lateral containment fins 104 and 105 by any suitable method, such as sewing.

In various embodiments, the separate containment fins can be bonded to the base sheet in any suitable manner. For example, the containment fins may be sewn to the base sheet, heat bonded, adhesive bonded, ultrasonically bonded, seam taped, or the like, or combinations thereof. In embodiments where the bag is fluid impervious, the separate containment fins are attached to the base sheet to provide a fluid impervious seal. The fluid-tight seal is believed to prevent leakage from the bag until the absorbent fitting is capable of consuming fluid.
In some embodiments, the fluid impervious seal is created, at least in part, by using ultrasonic bonding. Ultrasonic bonding fuses the base sheet material to the containment fin material. Ultrasonic bonding can use any suitable bonding pattern to regulate the bond strength of the seal. For example, the ultrasonic bonding pattern may be one or more rows of striped bonds. For example, in some embodiments, the bonding pattern may include three rows of offset striped joins as illustrated in Figure 13. In other modalities, the ultrasonic bonding pattern may

In other modalities, the ultrasonic bonding pattern You can include one or more rows of point joins. For example, in some embodiments, the join pattern may include two rows of offset point joins as illustrated in Figure 24. Ultrasonic bonding can be accomplished using a standard ultrasonic horn and anvil. In some embodiments, ultrasonic bonding can be created using a sonic sewing machine. A suitable machine is available from Sonobond and has the model number LM920.
The use of ultrasonic bonding is believed to be beneficial in some ways more than sewing because no holes are created in the containment flap and therefore the integrity of the bag is preserved. Similarly, the use of ultrasonic bonding is believed to be beneficial in some embodiments more than the seam tape because the base sheet and / or the containment fins may melt at the typical application temperature of the seam tape. In some embodiments, the base sheet is made of a polyurethane and polyester laminate and the containment fins are made of a polyurethane and polyester laminate. In these modalities, the base sheet and the containment flap can

For example, referring now to Figure 29, the second end containment flap 336 is illustrated with a stop of the absorbent fitting 351. In this embodiment, the stop of the absorbent fitting 351 is illustrated as an ultrasonic joint that limits the insertion depth of the absorbent fitting in the second end containment fin 336. In another example, the second end containment fin 150 of the Figure 18 is illustrated with an accessory stop 147 which is an ultrasonic junction between the second end containment fin 150 and the base sheet 106.
In embodiments having one or more absorbent accessory stops, the length of the bag floor and the area of the bag are defined in part by the containment flap seal and in part by the stop of the absorbent accessory. For example, referring back to Figure 28, the location on the base sheet 338 where the stop of the absorbent fitting 351 will be formed is shown with a broken line for illustration purposes. In modalities with the stop of the absorbent accessory 351, the floor of the bag 358 defines a length of the floor of the bag 360 and an area of the floor of the bag 365. In these modalities, the length of the floor of the

In embodiments that include one or more absorbent accessory stops, the floor of the bag can also define a reservoir portion that extends between the absorbent accessory stop and the containment flap seal below a containment flap. For example, referring back to Figures 28 and 29, the floor of bag 358 defines a reservoir portion 359 that extends from the top of absorbent fitting 3 51 to the end portion 363 of containment flap seal 344. In another example, referring now to Figure 18, bag 118 includes a reservoir portion 145 extending from the stop of absorbent fitting 147 to end flap seal 117. As previously discussed, the insert stops can be of any suitable length or width and can be positioned at any suitable depth within the first end containment cavity and / or the second end containment cavity.

In various embodiments, the reservoir portion can be about 50 to 70mm or about 60mm long.
The floor of bag 358 further defines a first end section 366, a second end section 367, and a center section 368 in longitudinal direction 48. Center section 368 extends between the first end section 366 and the second end section 367. The first end section 366 defines a width of the first end section 369 and a length of the first end section 370.

In some embodiments, the absorbent fitting may substantially lack fluid impervious materials. In some embodiments, the absorbent fitting does not include a fluid impervious barrier layer. In comparison, many absorbent articles include a fluid impervious backsheet or baffle that is provided to prevent fluid from coming into contact with the wearer's clothes or a delay layer that is provided to slow or deflect the fluid. In the present invention, the absorbent fitting is positioned within the fluid impervious bag and thus does not require a fluid impervious layer as part of the absorbent fitting. Additionally, this design is believed to be beneficial in some embodiments compared to conventional accessories because fluid can be absorbed within the absorbent accessory throughout the pad, including the front surface towards the body, the front surface towards the garment, and the sides. Additionally, omission of a fluid impervious layer eliminates the risk of fluid being trapped between the fluid impervious bag and the absorbent fitting
