  • Publication number: 20070078424
    Abstract: An absorbent article is curved in a saucer like shape in the transverse direction. The absorbent article offers not only a better fitting and feeling product to the wearer, but also has better flow characteristics. The article is formed by having an absorbent core that is made from multiple strips of absorbent material arranged in a stepwise manner so as to form a gradient. These strips may be of uniform or varying width and maybe made from a combination of one or more suitable material types.

  • Publication number: 20070000936
    Abstract: A container for one-handed pop-up dispensing plural wiping sheets. The container comprises a housing having a hollow interior in which an array of wiping sheets is disposed. The housing includes an aesthetically pleasing opening whose perimeter defines a non-regular shaped icon representing a realistic, fanciful or otherwise ornamental object. The opening has a first portion and a second portion. The first portion is of sufficient size and shape to enable an adult to extend his/her fingers therethrough to grasp one sheet of the array to pull the sheet into it and then slide the sheet into the second portion. The second portion frictionally engage the sheet slid into it to cause that sheet to be separated from the remaining sheets in the array to remove that sheet from the container.

  • Patent number: 6575949
    Abstract: A diaper is provided which includes a chassis having front, rear, and crotch portions. The chassis includes a topsheet, backsheet, core and pair of ears. Each ear includes a topsheet, backsheet and proximal, distal, first connecting, and second connecting edges. The first connecting and second connecting edges connect the distal to proximal edges. The proximal edge is integral to the chassis. Each ear has an elastic layer sandwiched between its topsheet and backsheet. Each elastic layer has first and second edges which are secured to the ear topsheet and backsheet. The elastic layer has a central portion not secured to either the ear topsheet or backsheet. Each ear topsheet and backsheet has perforations. The tearable portion is adjacent to the central portion. Each ear may be pulled away from the chassis causing the ear topsheet and backsheet to tear at the perforations thereby exposing the elastic layer.

  • Patent number: 6575950
    Abstract: A disposable absorbent article is provided which includes a chassis having a front portion, a rear portion, a crotch portion, a topsheet, a backsheet, an absorbent core, and a pair of ear portions integral to the backsheet. Each ear portion has proximal, distal, first connecting and second connecting edges. The first and second connecting edges connect the distal to the proximal edges. The proximal edge is integral to the topsheet. Each ear portion has an elastic layer having first and second edges where the first edge and second edge are secured to the backsheet. The elastic layer has a central portion not secured to the backsheet. The ear portion has a tearable portion extending from the first to the second connecting edges and extends along the central portion of the elastic layer. A fastener joined to each of the elastic layers secures the disposable absorbent article.

  • Patent number: 5879782
    Abstract: This invention relates to a process for forming a single-layer, durably wettable polymeric web having a plurality of apertures. This process comprises melting a mixture of at least one thermoplastic polymer and at least one migratable surfactant and extruding the mixture to form a single-layer, substantially continuous polymeric film. The film is then apertured using high pressure fluid flows. Aperture formation is conducted when the single-layer polymeric film has a contact angle of at least about 30.degree., to minimize wash-off of the surfactant impregnated in the polymer web. The invention also relates to durably-wettable apertured webs.
