Publication number: 20120296304Abstract: An absorbent article that contains a topsheet having embossed regions is provided. The embossed regions propagate in a longitudinal direction of the article in the form of a wave having one or more alternating crests (peaks) and troughs (valleys). Such a wave pattern helps slow down the flow of bodily fluid by directing it along a tortuous path defined by the densified edges rather than in a straight line. Among other things, this reduction in flow rate can help provide sufficient time for the absorbent core to absorb the fluid, which is particularly helpful when it is already partially filled with fluid. Nevertheless, bodily fluids can still sometimes pool near the crests and/or troughs and result in leakage. To help counteract this tendency, the present inventors have discovered that a plurality of apertures can be employed in the topsheet that are arranged in a column that generally extends in a longitudinal direction of the article.Type: ApplicationFiled: May 19, 2011Publication date: November 22, 2012Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Priscilla Goh Eng Choo, YeinSze Ong, Meijia Ng, SangWook Lee, DooHong Kim, Franz Aschenbrenner

The fluid-shrinkable member extends in a longitudinal direction of the article so that at least a portion of the member is located adjacent to an end of the topsheet. At least a portion of the end of the topsheet remains generally unbonded to the baffle. Thus, when the fluid-shrinkable member contracts upon contacting a fluid insult, the end of the topsheet can rise outwardly from the plane of the absorbent article. The raised area creates a barrier to the leakage of fluids from the center of the article towards its end.Type: ApplicationFiled: May 19, 2011Publication date: November 22, 2012Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Meijia Ng, Sangwook Lee, YeinSze Ong, Doohong Kim, Priscilla Goh Eng Choo, Franz Aschenbrenner

Patent number: 8227658Abstract: A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g.Type: GrantFiled: December 14, 2007Date of Patent: July 24, 2012Assignee: Kimberly-Clark Worldwide, IncInventors: Bo Shi, James H.
