As the combined continuous topsheet web, liquid acquisition layer, and absorbent core advance through the embossing nip, the rotating patterned embossing roll contacts the continuous topsheet web. And the rotating anvil roll contacts the absorbent core. By advancing the topsheet together with the acquisition layer and absorbent core through the embossing nip, a relatively deep pattern can be embossed into the topsheet than otherwise might be possible when embossing relatively thin topsheet web materials.

The side elastic members lie left and right of a front portion of the central absorbent core. The side absorbent cores lie left and right of rear and middle portions of the central absorbent core. In the diaper, by contraction of the side elastic members, the side absorbent cores come into close contact with the insides of thighs of a wearer, and urine is prevented from leaking from leg circumferences. Since the side absorbent cores are positioned left and right of the rear and middle portions of the central absorbent core, portions of the wearer's leg circumferences in the vicinity of the front are not covered with the side absorbent cores, and interference with leg movement of the wearer is prevented.

  • Patent number: 8388587
    Abstract: A disposable urine collection pouch made from diaper-like material formed in the shape of an elongated tube having an open top end and a closed bottom end. The open top end includes a funnel that leads from the opening down into the elongated tube. The elongated tube includes a superabsorbent layer to lock in and retain moisture introduced into the pouch. The funnel is made from a resilient material that flexes between a default closed position and an open position upon the exertion of sufficient and appropriate pressure by a user. After use, the pouch may be folded and disposed of in a plastic bag or otherwise deposited in a trash receptacle.

  • Publication number: 20120277712
    Abstract: An article to be worn on the lower torso of a wearer, such as pants or diapers. The article exhibits snug fit on a wearer through a particular cooperative arrangement of the side panels and the centre strip. It may further exhibit a particular bulging such as in the hip region of the wearer, and/or may include hoops such as for encircling the legs of a wearer. The article relates further to a simple manufacturing process for such articles. In a particular variant of the process, “multilane” manufacturing may be employed also to larger size article. In another particular variant, side margins of parts of the article can be connected without connecting these to further underlying parts.

  • Patent number: 8292865
    Abstract: The present invention relates to absorbent articles and non-absorbent articles which comprise at least one improved double-sided soft and elastic material composite. The composites according to the invention may also be breathable. The composites are produced by incrementally stretching a laminate of an elastic layer between two non-elastic cloth-like layers. The non-elastic cloth-like layers tear during stretching such that the elasticity of the laminate after stretching is substantially the same as the elasticity of the film elastic layer.

  • Patent number: 8273942
    Abstract: A disposable absorbent article, such as a disposable diaper. The disposable absorbent article has a topsheet with apertures large enough for low-viscosity fecal material to pass through to a fecal material storage element. The fecal material storage element immobilizes the fecal material in position for dewatering, so that the solid components of the fecal material are separated from the liquid components of the fecal material and the liquid components can be absorbed by an absorbent core. This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed. The fecal material storage element may extend beyond one or more edges of the absorbent core.
