Estimating the term…
Absorbent products are disclosed comprised of multiple components. At least two of the components are adhered together using an adhesive. In accordance with the present invention, the adhesive is applied in between the components according to a non-uniform pattern that varies as a function of distance. For example, the adhesive pattern may change according to at least one of pattern breadth or adhesive dose in weight per unit area. In one particular embodiment, the pattern contains a swirl-like pattern containing a plurality of loops. Over a particular distance, a change may occur in the size of the loops, in the density of the loops, and/or in alternating between loops and a linear bead. In this manner, placement of the adhesive is carefully controlled in order to counteract mechanical stresses that are placed on the absorbent product during use.

An absorbent garment comprising:
An absorbent product comprising multiple components, one of the components comprising an outer cover, while another component comprising an absorbent structure, the outer cover including an exterior surface and an interior surface, the absorbent structure being located adjacent the interior surface of the outer cover;
An absorbent article comprising two absorbent layers joined together by an adhesive applied in a pattern by a nozzle, the pattern having a first portion and a second portion, the pattern extending generally in a first direction in the plane of the article, the article also having a second direction in the plane of the article normal to the first direction, wherein at least one parameter selected from the dosage of the adhesive per unit length in the first direction and the breadth of the adhesive in the second orthogonal direction varies along the first direction, such that the at least one parameter measured in the first portion of the pattern differs from the corresponding at least one parameter measured in the second portion by at least 20%.
