DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to disposable pull-on garments which are donned by inserting the wearer's legs into the leg openings and sliding the garment up into position about the lower torso. Examples of such disposable pull-on garments include disposable underwear, pull-on diapers, training pants, and disposable panties for menstrual use. The present invention more particularly relates to unitary disposable absorbent pull-on garments such as pull-on diapers, training pants, incontinent pull-on briefs, and the like, which provide improved wearer comfort, increased leakage protection, and sustained dynamic fit.
BACKGROUND OF THE INVENTION
Infants and other incontinent individuals wear disposable absorbent articles such as diapers to receive and contain urine and other body exudates. Absorbent garments having fixed sides (e.g., training pants or pull-on diapers) have become popular for use on children able to walk and often who are toilet training. In order to contain body exudates as well as to fit a wide variety of body shapes and sizes, these pants must fit snugly about the waist and legs of the wearer without drooping, sagging or sliding down from its position on the torso as well as fitting larger wearers without causing irritation to the skin due to the product being too tight. Thus, the pant must have elastic extensibility in the waist and legs with the elastic features providing a high degree of stretch.
Many training pants and pull-on diapers use conventional elastic elements secured in an elastically contractible condition in the waist and leg openings. Typically, in order to insure full elastic fit about the leg and the waist such as is provided with durable undergarments, the leg openings and waist opening are encircled with elasticized bands of rubber or other materials positioned along the curve of the opening. These pants are typically characterized as "balloon style" pants because of the contraction caused by the elasticized bands in specific zones of the product while the remaining material tends to blouse. Examples of such training pants are disclosed in U.S. Pat. No. 5,171,239 to Igaue, et al. on Dec. 15, 1992 and U.S. Pat. No. 4,610,681 to Strohbeen, et al. on Sep. 9, 1986. Although these pants will allow fit of various waist and leg sizes due to the fact that the contractive elastic openings will expand to accommodate various size wearers, these products still fit a limited range of fit sizes because the elastic elements are in contraction and do not have a high degree of stretch. The narrow elastic bands used in the waist opening and the leg openings also tend to concentrate the "fitment" forces in a narrow zone of the wearer's body leading to increased incidence of skin marking of the wearer. Further, the sides and remainder of the products are typically not elastically extensible thereby reducing the fit.
In order to solve this deficiency in balloon-style pants, some manufacturers have positioned elastic strands across the entire front and back regions of the product. For example, WO 93/17648 published on Sep. 16, 1993, discloses a pant-type diaper in which the front and/or the rear parts are elastically contractible and the ends of the absorbent core are disposed in these regions. These additional elastic strands act to contract the entire front and back waist parts of the pant including the end areas of the absorbent core. This allows greater expansion of the product in the waist region but causes the absorbent core to be gathered and bunch at the waist opening. This gathering and bunching results in a higher risk of leakage at the waist since channels are created along the absorbent core that allows body exudates to wick or flow out of the waist. This gathering of the absorbent core also affects the appearance of the product in that the product does not appear as aesthetically pleasing as the balloon style pants.
Another type training pant is shown in U.S. Pat. No. 4,940,464 issued to Van Gompel, et al. on Jul. 10, 1990, wherein a pant-like garment is
