In lieu of hook strips, the back waist region may include one or more tape tabs each having one surface attached to the back waist region and an opposed hook surface for releasable engagement with a correspondingly aligned loop surface. A weakened line, e.g., a perforated line may be provided in the front waist region which can be readily torn away in order to inspect the diaper.

Abstract: A breathable disposable absorbent article such as, for example, a diaper, is provided which comprises a top sheet, a backsheet and an absorbent layer therebetween. The top sheet and the backsheet are sealed together to form a unitary structure and include a medial cutout portion on each side which define openings for the leg of the wearer. One or more so-called landing zones are provided on the backsheet, adapted to releasably adhere to fastening tabs located at each side of the article. A liquid impervious sheet or film is laminated to the top surface of the backsheet in order to prevent leakage of fluids and exudates.

Abstract: A method is provided for continuous mass production of winged absorbent articles, including T-shaped absorbent articles, by attachment of wing portions to the chassis of the absorbent article which comprises a topsheet, a backsheet and a core sandwiched between the topsheet and the backsheet. The method comprises feeding at least one web of wing-making material, which may be at least partly elasticated, simultaneously attaching landing zones in spaced apart relationship on a surface of the web, attaching tape tabs on the edge of the web, folding the web longitudinally in a generally Z-fold configuration, feeding the chassis of the absorbent article in the general direction of the web, severing individual folded wing portions from said web and attaching the winged portions to the chassis at predetermined spaced intervals.

Abstract: A disposable absorbent article such as, e.g., a T-shaped diaper comprising two portions, a lateral portion (backwaist) having two lateral segments or wings for wrapping around the waist of a wearer of the diaper, and a second vertical portion or insert which is adapted to be passed under the crotch of the wearer and folded thereover. A uniquely designed tape tab located at the outer lateral end of one wing assures more perfect and comfortable fit. Tape tabs are also provided at the distal ends of vertical portion for engagement onto landing zones disposed on the surface of each wing. These tape tabs may have the same general construction as the tape tab on the diaper wing. The dimensions of the diaper and several of its components and the relative locations of these components are important factors which contribute to improved fitness and functions of the diaper.

Abstract: An improved coversheet material for use in multi-layer boards. The improvement comprises a layer of continuous filament and a layer of fibrous web. The fibrous web is a blend of thermoplastic fibers. The thermoplastic fibers are high melt point fibers and low melt point fibers. The layer of continuous filament and the layer of fibrous web are bonded together by passing the layers between a pair of heated rolls which are under pressure. As the heat from the rolls melts the low melt point fibers, the pressure exerted on the rolls puts the melted fibers into contact with the high melt point fibers and the layer of continuous filament. As the melted fibers cool they secure themselves, the high point fibers and the continuous filament layer together to form an integral structure. The continuous filament provide strength to the coversheet material while the high melt point fibers in the fibrous web provide compatability with core materials used in a multi-layered board.
