Patent number: 10137040Abstract: An absorbent article, such as a diaper, comprising a topsheet, a backsheet and an absorbent core. The absorbent layer comprises a longitudinally-extending central portion, and a first and second side portions disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides between the central portion and the side portions. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further comprises at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core. The liquid management layer comprises a central portion, first and second side portions, and first and second folding guides which are at least partially superposed with the folding guides of the absorbent core.Type: GrantFiled: February 16, 2016Date of Patent: November 27, 2018Assignee: The Procter & Gamble CompanyInventors: Bruno Johannes Ehrnsperger, Hans Adolf Jackels, Claus Peter Stoelzel, Christine Elisabeth Zipf

Patent number: 10070997Abstract: A disposable absorbent pant having a belt structure and a longitudinally channeled absorbent core structure is disclosed. The channels include at least one shorter, at least partially transversely-oriented secondary channel in the front and/or rear, to provide a hinge structure in the core, enabling the core to flex laterally and reduce the likelihood of undesirable bulging in the front and/or rear of the pant while it is worn, after the core has absorbed liquid and stiffened longitudinally as a result of the channeled structure.Type: GrantFiled: January 16, 2015Date of Patent: September 11, 2018Assignee: The Procter & Gamble CompanyInventors: Masaharu Nishikawa, Gary Dean LaVon

Patent number: 9956586Abstract: Methods for producing composite structures with a plurality of absorbent foam particulates between substrates, wherein the method includes providing a carrier substrate. The carrier substrate may comprise a pre-determined pattern. The pre-determined pattern may comprise z-directional deflections. The methods may also comprise placing a plurality of absorbent foam particulates onto the carrier substrate, forming a loaded carrier substrate. The methods may further comprise providing a particulate settling means enabled to affect the loaded carrier substrate, affecting the loaded carrier substrate, forming a settled carrier substrate. The methods may further comprise associating a cover with the settled carrier substrate, forming a composite structure.Type: GrantFiled: November 10, 2015Date of Patent: May 1, 2018Assignee: The Procter & Gamble CompanyInventors: Aleksey Mikhailovich Pinyayev, Steven Ray Merrigan

Patent number: 9907708Abstract: The subject of the invention is a wound care article for extraction and control of wound fluids, comprising at least one first fluid-absorbing structure (1; 10; 36), which is surrounded by a liquid-permeable, first enclosure (2), and a liquid-permeable, second enclosure (3) comprising two enclosing surfaces (13.1, 13.2). The wound care article is thus characterized in that the first enclosure (2) is covered or supported on at least one of its flat sides (4.1, 4.2) by at least one fluid-absorbing material layer (6.1, 6.2; 6.3), which is arranged (FIG. 1a) between the first enclosure (2) and one of the enclosing surfaces (13.1, 13.2) of the second enclosure (3).Type: GrantFiled: March 18, 2014Date of Patent: March 6, 2018Assignee: BSN MEDICAL HOLDING GMBHInventor: Birgit Riesinger

Patent number: 9901495Abstract: The present invention addresses the problem of providing an absorbent article that is provided with a liquid-permeable layer, said liquid-permeable layer having convex portions that are hollow inside, has an improved ability to transfer menstrual blood from the liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer (in particular, the internal cavities in the convex portions). To solve this problem, provided is a sanitary napkin provided with a liquid-permeable top sheet, a liquid-impermeable back sheet and an absorbent body that is interposed between the top sheet and the back sheet, wherein convex portions, said convex portions being hollow inside and formed in an excretion orifice contact region of the top sheet, are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000.Type: GrantFiled: August 28, 2013Date of Patent: February 27, 2018Assignee: UNICHARM CORPORATIONInventor: Masashi Uda

Patent number: 9844456Abstract: Methods are disclosed for converting on a mass scale elongated material webs into finished parts or devices. Slits form strands in a web, the strands comprising interconnected objects which correspond to parts of finished devices. Strands are combined with additional webs to form a material laminate from which finished devices are die cut. The methods are suitable for a range of converting applications including medical devices, particularly the external nasal dilator. Complex dilator devices produced from the methods are formed as a single body truss having horizontal regions adapted to engage outer wall tissues of first and second nasal passages of a nose. When in use the dilator stabilizes or expands nasal outer wall tissues and prevents the outer wall tissues from drawing inward during breathing. Methods of manufacture comprise separate steps for fabricating and assembling the elements and layers of finished dilator devices and for packaging finished devices individually or in groups.Type: GrantFiled: December 23, 2013Date of Patent: December 19, 2017Assignee: CORBETT LAIR INC.Inventor: Joseph Vincent Ierulli
