ABSTRACT:
FIELD
The present invention relates to disposable pull-on garments. 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 disposal handling after its soil.
BACKGROUND
Infants and other incontinent individuals wear disposable absorbent articles such as diapers to receive and contain urine and other body exudes. 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. These training pants have side panels which edges are seamed together to form two leg openings and a waist opening. These pants need to fit snugly about the waist and legs of the wearer without drooping, sagging or sliding down from its position on the torso to contain body exudes.
After a training pant or pull-on diaper is soiled by urine or body exudes, it is removed from the wearer's body by tearing open the seams of the side panels. The removed training pant or pull-on diaper then is folded so that the soiled portion is wrapped inside for disposal. To prevent the soiled training pant or pull-on diaper from being unfolded and/or to keep the soiled portion inside, it is desired that such training pant or pull-on diaper has a disposal means which secures or keeps the folded diaper in the folded state. Examples of such training pants are disclosed in U.S. Pat. No. 5,575,784 to Ames-Ooten et al. on Nov. 19, 1996, and European Patent Publication Nos. EP623330 and EP0732094.
However, the existence of such disposal means sometimes tends to cause a leakage of contained urine or body exudes from the sides of the folded diaper especially when the side edges of the diaper are not appropriately folded inwardly. Further, such disposal means also tends to be an obstacle to the wearer's movement and/or decrease the diaper's good appearance.
SUMMARY
The present invention is directed to a disposable pull-on garment. The disposable pull-on garment of the present invention comprises a chassis having a front region, a back region and a crotch region between the front region and the back region. The chassis comprises a liquid pervious topsheet, a liquid impervious backsheet associated with the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The disposable pull-on garment of the present invention further comprises front side panels extending laterally outwardly from each side of the chassis in the front region; back side panels extending laterally outwardly from each side of the chassis in the back region; seam panels each extending laterally outwardly from each of the front and back side panels; seams each joining the corresponding seam panels in an overlap manner to make an overlapped seam structure, thereby forming two leg openings and a waist opening; and a disposal means joined to the at least one of the front and back side panels for allowing the pull-on garment to be secured in a configuration that provides a convenient disposal.
These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.
