(Journal of Engineering)
– From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Roe, Donald Carroll (West Chester, OH); Feist, Barry Robert (Cincinnati, OH); Comstock, Krista Beth (Mason, OH); Goodlander, Lisa Jane (White Oak, OH), filed on March 25, 2011, was published online on April 15, 2014.
The patent's assignee for patent number 8697937 is The Procter & Gamble Company (Cincinnati, OH).
News editors obtained the following quote from the background information supplied by the inventors: "Infants and other incontinent individuals wear absorbent articles such as diapers to receive and contain urine and other body exudates. Absorbent articles function both to contain the discharged materials and to isolate these materials from the body of the wearer and from the wearer's garments and bed clothing.
"Diaper manufacturers have attempted to improve the appearance and function of diapers by providing a more garment like look and improving fit by introducing stretch. However, often times the features influencing fit adversely affect the appearance. For instance, disposable diapers with side stretch features have used stretch and force profiles to provide good initial fit as well as good sustained fit. Disposable diapers offering such side stretch features are often multipiece designs composed of diaper chassis with stretchable side panels bonded to and extending from at least one of the longitudinal side edges. Such multipiece designs often appear less garments-like and require decorative features to compensate. In addition, the bond extending parallel to the longitudinal side edges of the diaper causes forces to be very similar or equal along the stretch panel from top to bottom when the diaper is applied on a wearer. The equal forces result in either red marking of the skin at the top of the leg, poor sustained fit about the waist, or both. In addition, the edges of the side panels tend to fold or roll inward toward the center of the side panel exhibiting a poor fit that appears less garment-like.
"Therefore, it is an object of the present invention to provide a disposable absorbent article capable of providing improved initial fit, sustained fit, and reduced red marking of the wearer's skin while appearing more garment-like."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "The present invention provides a disposable absorbent article to be worn about the lower torso of a wearer. The disposable absorbent article includes at least one pair of side panels connecting a first waist region to a second waist region forming a waist opening and a pair of leg openings. Each side panel includes a waist region, a hip region and a leg region wherein the waist region, the hip region and the leg region differ structurally, functionally and visually to provide an improved initial fit and a sustained fit while exhibiting a garment-like appearance.
"In one embodiment, a pair of side panels is disposed in the second waist region. Each side panel includes a waist region, a hip region and a leg region, where the waist, hip and leg regions differ structurally, functionally and visually. Each side panel also includes a fastener for releasably attaching the side panel to the first waist region.
"In another embodiment, a first pair of side panels is attached to the second waist region and second pair of side panels is attached to the first waist region. The first pair of side panels is attached to the second pair of side panels forming a pant having a waist opening and a pair of leg openings. Each pair of side panels includes a waist region, a hip region and a leg region wherein the waist region, hip region and the leg region differ structurally, functionally, and visually."
