Patent number: 8304499Abstract: Disclosed are polymer compositions having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce oxygen-scavenging compositions.Type: GrantFiled: April 29, 2011Date of Patent: November 6, 2012Assignee: Eastman Chemical CompanyInventors: Marcus David Shelby, Wesley Raymond Hale, Thomas Joseph Pecorini, Martin Emerson Rogers, Spencer Allen Gilliam, Michael Duane Cliffton, Mark Edward Stewart

Publication number: 20120204410Abstract: A method of assembling a tampon applicator includes providing a barrel with internal ridges that define a guide channel having an effective diameter. The method includes providing a plunger that has a finger flare with a circular shape and a flare diameter that is at least 15% larger than the effective diameter of the guide channel. The method includes assembling the plunger and the barrel by pushing the finger flare into the guide channel and deforming the finger flare into a non-circular shape while moving the finger flare through the guide channel. The method includes moving the finger flare out of the plunger end of the barrel and reestablishing the circular shape of the finger flare.Type: ApplicationFiled: February 10, 2011Publication date: August 16, 2012Inventors: Gary Michael Mastalish, Marcus David Weiher, Gary Alan Turchan, Thomas William Van Den Bogart

Patent number: 8162872Abstract: The present invention provides an improved tampon applicator having a grip area which provides the user better gripping ability. The grip area may be an area between two ridges on the outer tube of the applicator. In the alternative or in addition to the ridges, the grip area may be a raised pattern which is raised by a distance of between about 0.10 mm and about 0.75 mm. The present invention also provides an improved petal design for a tampon applicator. In this embodiment of the present invention, the petals are separated from each other on all sides by a non-linear gap and the gap is not parallel with the longitudinal axis of the tampon applicator.Type: GrantFiled: December 29, 2005Date of Patent: April 24, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Adrienne Rae Loyd, Steven Anthony Moore, Marcus David Weiher, Thomas William VanDenBogart

Publication number: 20100295200Abstract: Disclosed are void-containing polyester shrink films which show excellent density retention upon exposures to high temperatures. The films have high shrinkage and retain their low density after processing under conditions of temperature and moisture used in typical recycling processes. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for void-containing polyester shrink films having high shrinkage and low density after exposure to elevated temperatures.Type: ApplicationFiled: August 6, 2010Publication date: November 25, 2010Applicant: EASTMAN CHEMICAL COMPANYInventors: Marcus David Shelby, Candace Michele Tanner, Mark Elliott Tincher, Rondell Paul Little, JR.
