Definitions
- the invention is concerned with disposable diapers and incontinent articles having refastenable mechanical closures and is specifically concerned with improvements in fit and closure stability.
- PSA fastening tabs Conventional commercial disposable diapers and adult incontinent products typically use pressure- sensitive adhesive (PSA) fastening tabs to close the diaper.
- PSA fastening tabs extend beyond the side edge of the diaper at a first ear or corner portion and attach to an opposing ear or corner portion as the opposing ears are overlapped in placing the diaper around the user.
- the PSA fastening tab is permanently attached at a "manufacturers end" to one ear directly adjacent the side edge of that ear and refastenably attached at an inward location on the opposing ear or corner portion by a free end of the PSA fastening tab.
- An improvement on the above basic adhesive closure system is the inclusion of a secondary pair of closure elements, which also engage when the two opposing ears are overlapped.
- This so-called “inner fastening means” is generally formed by placing a fastening element on an inner face the first ear, which engages with a corresponding or matched fastening surface or element on the outer face of the opposing ear. In this manner, the ears are directly secured to each other at their overlapping faces as well as by the conventional PSA fastening tab.
- the use of secondary closure elements is proposed in U.S. Patent No. 4 / 699,622, which describes an elasticated diaper using an outer fastening tab and an inner fastening means.
- the conventional outer fastening tab extends from the __ longitudinal side edge at a first corner of the diaper.
- the inner fastening means is described as potentially including "VELCRO" strips, adhesive patches, buttons or snaps, but is preferably a mechanical fastening element placed on the outer face of the second opposing corner that engages with the topsheet nonwoven forming the inner face of the first corner. Specific improvements to the arrangement in U.S. Patent No. 4,699,622 are described in U.S. Patent No.
- 3,610,244 also proposes secondary closure elements.
- the patent describes using a conventional PSA fastening tab on a first corner of the diaper.
- the inner face of this first corner contacts a PSA patch located on the outside face of the second opposing corner when the two opposing corners are attached in an overlapping relation with the conventional PSA fastening tab.
- the four points of adhesive attachment are described as providing more secure fit for active babies.
- the invention is directed to a mechanical, or hook and loop, closure system for a disposable garment, specifically, disposable incontinent products such as a diaper.
- the male mechanical fastening tab has a first end extending beyond the outer side edge of a first ear or corner, and a second end extending inward of the outer side edge of the first corner. Both ends of the mechanical fastening tab are engagable with a mating, woven, stichbonded, knitted or the like, or nonwoven web on the second opposing ear corner, the mechanical fastening tabs two ends serve as an outer mechanical fastening tab element and an inner panel face-to-panel face fastening element.
- the two mechanical fastening elements provided by the invention closure system provide improved fit and closure stability using a simple and easy to apply single mechanical fastening tab.
