Abstract

Here we describe a cloth diaper design inspired by the 1973 patented design of Pampers® by Proctor & Gamble [1] utilizing double gussets, a design feature that has become common practice in the design of absorbent garments [2-6]. Although cloth diapers have comparable functionality to disposable diapers, there are two frequent problems in current cloth diaper design that remain to be solved before the majority of caregivers embrace cloth diapering. The first problem is waste leakage from the leg openings of the diaper. The second is the requirement to remove soiled internal absorptive material by hand prior to laundering in the so-called, “pocket” cloth diaper (a cloth diaper composed of a waterproof exterior panel joined to a continuous permeable inner panel around the majority or entirety of the diaper margin, with access to the internal space left for the insertion and removal of waste-absorbent material). The goal of this paper is to make freely available our solution to these problems in our ChampTM pocket diaper (GoGreen Enterprises LLC, Boulder, CO). The ChampTM pocket diaper has improved design elements that provide convenience for the caregiver together with improved hygiene. The first improved feature in the ChampTM is the use of Dual GussetsTM technology as previously described and patented in disposable and cloth diapers 20-30 years ago [1-6], wherein dual elastic leg gussets provide improved fit around the baby’s thigh for superior waste containment. In this design, a first set of elastic gussets is disposed between a second set of elastic gussets within the fluid- permeable inner panel of the diaper. The second improved design element is the use of a novel sleeve-like design feature that incorporates dual openings in the interior diaper “pocket.” This is a unique feature of the ChampTM pocket diaper. The dual pocket openings allow internal absorptive material to agitate, or tumble out of the internal pocket space automatically during the beginning of the wash cycle. Thus, the need to hand-remove soiled absorptive material from the diaper pocket prior to laundering is eliminated.

ABSTRACT

Here we describe a cloth diaper design inspired by the 1973 patented design of Pampers® by Proctor & Gamble [1] utilizing double gussets, a design feature that has become common practice in the design of absorbent garments [2-6]. Although cloth diapers have comparable functionality to disposable diapers, there are two frequent problems in current cloth diaper design that remain to be solved before the majority of caregivers embrace cloth diapering. The first problem is waste leakage from the leg openings of the diaper. The second is the requirement to remove soiled internal absorptive material by hand prior to laundering in the so-called, "pocket" cloth diaper (a cloth diaper composed of a waterproof exterior panel joined to a continuous permeable inner panel around the majority or entirety of the diaper margin, with access to the internal space left for the insertion and removal of waste-absorbent material). The goal of this paper is to make freely available our solution to these problems in our Champ™ pocket diaper (GoGreen Enterprises LLC, Boulder, CO). The Champ™ pocket diaper has improved design elements that provide convenience for the caregiver together with improved hygiene.

     The first improved feature in the Champ™ is the use of Dual Gussets™ technology as previously described and patented in disposable and cloth diapers 20-30 years ago [1-6], wherein dual elastic leg gussets provide improved fit around the baby's thigh for superior waste containment. In this design, a first set of elastic gussets is disposed between a second set of elastic gussets within the fLuid- permeable inner panel of the diaper. The second improved design element is the use of a novel sleeve-like design feature that incorporates dual openings in the interior diaper "pocket." This is a unique feature of the Champ™ pocket diaper. The dual pocket openings allow internal absorptive material to agitate, or tumble out of the internal pocket space automatically during the beginning of the wash cycle. Thus, the need to hand-remove soiled absorptive material from the diaper pocket prior to laundering is eliminated.

BACKGROUND

Cloth diapers are becoming increasingly popular due to their reduced environmental impact and lifetime cost-savings. While many advances have been made in disposable diaper technology to improve waste containment over the past three decades, cloth diapers are only recently beginning to undergo similar advances in design. In fact, many of the advances in cloth diaper design and functionality in the past 25 years derived from large corporate investment in research and development within the disposabl...
