  • Patent number: 6429351
    Abstract: An absorbent article comprising a liquid-permeable casing sheet (1), a liquid-impermeable casing sheet (2) and an absorbent body (3) enclosed between the two casing sheets. The absorbent body (3) includes a liquid acquisition space (24) which consists of at least one cavity or one region of lower density than the density of an acquisition layer (19) located in said absorbent body (3) adjacent the space (24) and essentially in the same plane thereas. The acquisition layer (19) includes a material which when wetted increases in size in the thickness direction of the article (the z-direction). The article is mainly characterized in that the material in the acquisition layer (19) exhibits relatively low expansion in the plane of the article (the xy-direction) when wetted, such that the volume of the liquid-acquisition space (24) will increase by at least 100%, preferably by at least 200%, more preferably by at least 400% and most preferably by 900% when wetted.

  • Patent number: 6372953
    Abstract: Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section.

  • Patent number: 6368312
    Abstract: A disposable pull-on diaper includes a liquid absorbent core, and the core is joined to a topsheet in front and rear waist regions as well as in a crotch region but not joined to a backsheet in the front and rear waist regions. The topsheet and the backsheet are not joined to each other in their portions extending between longitudinally opposite ends of the liquid-absorbent core and a peripheral edge of a waist-opening. The diaper thus constructed prevents the core from being flexed or crooked.

  • Patent number: 6369290
    Abstract: A disposable absorbent article is provided with a odor control powder which is unscented in a dry state and releases a burst of fragrance when wetted, such as by human waste. The powder contains a relatively small amount of fragrance oil, such as 0.5% to 4% by weight, to prevent skin irritation to the wearer. The small amount of fragrance oil is microencapsulated in a starch which constitutes from about 50% to 90%, and preferably about 70%, of the total weight of the particles. Sodium bicarbonate is also included in the particulate odor control material in an amount ranging from 5.0% to 45%, and preferably about 25% by weight, of the total weight of the particles. The sodium bicarbonate promotes skin wellness by controlling the pH levels of the fragrance oil, starch and human waste. A small amount of flow agent is also contained in the particulate odor control material.

  • Patent number: 6350254
    Abstract: A medical device for fluid collection and method to fill multiple specimen tubes is disclosed. The device is designed to collect and transfer a specimen into a non-evacuated tube through an integrated open port. The device has no cannulas, either blunt or sharp, and therefore provides safety from skin puncture. The device has a non-evacuated test tube attached to the integrated open port. The tube is attached to the open port by a luer fitting in the tube's cap which is pressed into a receptacle detail on the device. A finger pad is held during collection of the specimen. The finger pad allows collection without the risk of contaminating the inside of the container. The container also contains a horizontal support platform which allows the device to be placed on a flat surface with or without the test tube attached without tipping over.
