ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an absorbent article having a refastenable mechanism. More specifically, this invention relates to a disposable absorbent article having a refastenable mechanism that improves body fit and reduces the likelihood of fluid leakage.
BACKGROUND OF THE INVENTION
Today, various disposable absorbent articles exist which are designed to absorb and retain body fluid and/or excrement. Examples of such articles include incontinence products such as pants, briefs and undergarments, baby diapers, feminine care menstrual pants, training pants, etc. While most of these articles perform satisfactorily for their intended purpose, some are difficult to remove from the body of the wearer. Many do not have a refastenable mechanism that allows the article to be easily adjusted during use or be easily removed from the wearer's body before the product is permanently discarded while maintaining an underwear like fit. Some of today's commercially available products do not conform well to the human body and this poor fit increases the likelihood of fluid leakage while the product is being worn. Therefore, there remains a need for a disposable absorbent article having a refastenable mechanism that will provide improved fit to the human body and reduce the likelihood of fluid leakage.
Now, a disposable absorbent article has been invented which has a refastenable mechanism that improves body fit and reduces the likelihood of fluid leakage.
SUMMARY OF THE INVENTION
Briefly, this invention relates to an absorbent article having a refastenable mechanism. The absorbent article has a front portion, a back portion and a crotch portion. The crotch portion connects the front portion to the back portion. The back portion has a first end and a second end. The back portion is divided into a first section and a second section. The first section is extendable in a transverse direction and has a length L

measured perpendicularly from the first end of the back portion to a line drawn parallel thereto. The second section has a length L
3
measured perpendicularly from the second end of the back portion to the line drawn parallel to the first end. The second section has a first side edge, a second side edge, a first area A

and a second area A

. The first area A
1
represents an area bounded by the first and second side edges, the second end, and the line drawn parallel to the first end. The second area A
2
represents an area bounded by first and second lines, the second end, and the line drawn parallel to the first end. The first and second lines are drawn perpendicular to the second end at points where the first and second side edges intersect the second end. The first and second lines intersect the line drawn parallel to the first end. The second section has a ratio A

/A
2
which ranges from between about 1.3 to about 3.5. First and second fasteners are secured to the back portion. An absorbent is secured to at least one of the front, back or crotch portions. Each of the first and second fasteners are releasably attached to the front portion to form a pant-like article having a waist opening and a pair of leg openings.
The general object of this invention is to provide an absorbent article having a refastenable mechanism. A more specific object of this invention is to provide a disposable absorbent article having a refastenable mechanism that improves body fit and reduces the likelihood of fluid leakage.
Another object of this invention is to provide an absorbent article having a refastenable mechanism that is easy to manufacture, is relatively inexpensive and is easy to use.
Still another object of this invention is to provide an absorbent article that can easily be adjusted to conform to a wearer's body.
