  • Patent number: 8377023
    Abstract: Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the absorbent articles have a percentage of stretch in the lateral direction at the widest portion in the front region of the article and/or in the back region in the range of from about 25% to about 150%. Additionally, at least about 70% of the above stretch resides in a first edge zone and in a second edge zone of the chassis. The first edge zone and the second edge zone are separated by a middle zone. The middle zone, which has the same length as each edge zone, is stretchable, but to a lesser extent than the edge zones. Through this construction, the absorbent article exhibits improved fit and appearance. Of particular advantage, the carefully controlled stretch properties prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.

  • Patent number: 8282619
    Abstract: A garment-like absorbent article includes an absorbent chassis that defines a waist opening and first and second leg openings. A longitudinal length of the chassis is optimized in a linear relationship with the waist circumference of the chassis, the circumference measured at 500 grams tension. With respect to the linear relationship, the thickness of the garment is substantially constant along the same line defined by the length and the circumference, and decreases as the y-intercept increases.

  • Patent number: 8066685
    Abstract: Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the articles exhibit stretch not only in the lateral direction but also in the longitudinal direction. Specifically, the articles have a biaxial stretch ratio, which refers to a ratio of stretch along the hip circumference of the article to the amount of stretch in the longitudinal direction, that is from about 1.0 to about 2.5, and particularly from about 1.1 to about 1.5. Absorbent articles made in accordance with the present invention are capable of accommodating a relatively large size range of wearers. The articles also exhibit improved fit and prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.

  • Patent number: 7704589
    Abstract: An absorbent article having a built-in size indicator is disclosed. The size indicator, for instance, comprises a stretchable panel that changes color when stretched. The panel may change color to indicate that the article is the correct size for the wearer or may change color to indicate that the article is too small. Still another embodiment, the stretchable panel may change from a first color indicating that the article is too large, to a second color that indicates the article is the correct size, and to a third color that indicates the article is too small. The stretchable panel may be made from any suitable color changing materials. For example, in one embodiment, the panel may include a gathered layer that is printed with a particular color only at the peaks of the gathered layer. As the gathered material is stretched, the material changes color due to the newly exposed regions. In other embodiments, the stretchable panel comprises a film that changes color when stretched.

  • Publication number: 20040254549
    Abstract: A personal wear article capable of alerting a wearer to the wearer's release of liquid body exudates. The article includes an absorbent structure and a wetness indicator adapted to receive said liquid body exudates. The wetness indicator stiffens as it absorbs the liquid body exudates and applies a tactile sensation against the wearer's skin. The wetness indicator is positioned relative to a portion of the absorbent structure having an absorbent capacity gradient such that the absorbent capacity of the absorbent structure increases as the absorbent structure extends generally from the position of the wetness indicator in a direction generally away from the position of the wetness indicator. In another embodiment, the article includes a temperature change agent responsive to the liquid body exudates to change the temperature of the liquid body exudates to thereby facilitate a temperature change sensation against the wearer's skin.
