Abstract
An absorbent article is described which may be formed at least in part of thermoplastic and other fibers. The article is densified along a first region and has a tear line defined in the first region. A second region of lower density than the first region is provided at the termination point of the tear line to assist in stopping tearing along the tear line. In addition, densified reinforcing regions can be provided outside areas where the tear line curves or switches directions. Perforations or cuts in the tear line may extend continuously around the corner of the tear line to assist tearing around the corner.
Claims20
An absorbent article comprising:
- a body comprised of fiber material;
- the body having a densified first region of fiber material of a first density and a second region of fiber material contained in the first region and being of a second density lower than the first density;
- a weakened area positioned within the densified first region to define at least one line in such first densified region, the line terminating in the second region, whereby the line comprises a tear line along which the article may be torn.
An absorbent article comprising:
- a body comprised of fiber material;
- the body including a densified strip of fiber material and the densified strip having a curved portion;
- a weakened area within the densified strip extending around the curved portion and defining a line, whereby the line comprises a tear line along which the article may be torn;
- and
- the body also including a densified reinforcing region of fiber material which is spaced from the densified strip and positioned to extend around the curved portion of the densified strip to reinforce the article.
An absorbent article comprising:
- a body comprising thermoplastic fibers and natural fibers;
- the body having a densified first region of fibers of a first density;
- perforations in the densified first region defining a line which extends in a first direction to a first location and abruptly changes direction at the first location to extend in a second direction, the perforations comprising a continuous cut at the first locations which extends in both the first and second direction, whereby the line comprises a tear line along which the body may be torn.
