| 20090238500 | ZIPPER AND ZIPPER-EQUIPPED BAG - A tearing guide strip | 09-24-2009 |
| 20090300891 | TAPE WITH INTERLOCKING DEVICE - A zipper-member-having tape | 12-10-2009 |
| 20100074562 | EASILY TEARABLE FASTENER TAPE, METHOD OF PRODUCING THE FASTENER TAPE, PACKAGING BAG WITH EASILY TEARABLE FASTENER TAPE, AND DEVICE AND METHOD FOR PRODUCING THE PACKAGING BAG - A belt-shaped base of a male member of a zipper tape attached to an inner surface of a bag body includes: a main body on which an engagement portion is provided; a first projecting portion provided on an opening-side of the main body; a thin portion connected to an opening-side of the first projecting portion; and a second projecting portion connected to an opening-side of the thin portion. A belt-shaped base of a female member includes: a main body; a first projecting portion; a thin portion; and a second projecting portion. When the zipper tape is fused onto the bag body, a space is provided between the thin portions and a film of the bag body. | 03-25-2010 |
| 20100215291 | Easily Openable Fastener Tape, Packaging Bag With Easily Openable Fastener Tape, And Method Of Manufacturing Easily Openable Fastener Tape - A belt-shaped base of a male member of a zipper tape attached on an inner surface of a bag body includes a main body provided with an engagement portion, a thin portion connected to an opening-side of the main body, a thick portion connected to an opening-side of the thin portion and a projecting portion provided on the thick portion. A female member is also provided with the same arrangement. When the zipper tape is fused with the bag body, a gap is provided between the thin portion and a film of the bag body and between the thin portion and a film of the bag body, so that the thin portions are easily bent. | 08-26-2010 |
| 20100236026 | CHUCK TAPE WITH CUT TAPE, ITS MANUFACTURING METHOD, AND PACKAGING BAG WITH CHUCK TAPE - A belt-shaped base of a female member of a zipper tape attached to an inner surface of a bag body has a wide portion that extends wider toward an opening of the bag body than a belt-shaped base of the male member. An open tape is disposed on the wide portion and a seal layer is laminated on a surface of the open tape. A first projecting portion is also provided on the wide portion. A second projecting portion is provided on an opening-side end of the belt-shaped base. The projecting portions have a substantially trapezoidal cross section. When the zipper tape is bonded to the bag body and is sealed by the seal layer, a gap is provided between the open tape and the first and the second projecting portions. | 09-23-2010 |

| 20080281067 | Modified Polytetrafluoroethylene Powder and Method for Producing Tetrafluoroethylene Polymer - The present invention provides a polytetrafluoroethylene powder having moldability/processability as well as electrical characteristics in microwave bands. The present invention is a modified polytetrafluoroethylene powder which has (1) a dielectric loss tangent at 12 GHz of not higher than 2.0×10 | 11-13-2008 |
| 20090264568 | METHOD FOR PRODUCING FLUORINE-CONTAINING POLYMER, AQUEOUS DISPERSION OF FLUORINE-CONTAINING POLYMER, 2-ACYLOXYCARBOXYLIC ACID DERIVATIVE, AND SURFACE ACTIVE AGENT - The present invention provides a method of producing a fluoropolymer, wherein polymerization using a carboxylate ester bond-containing carboxylic acid derivative as a surfactant in an aqueous medium to give the fluoropolymer is conducted, the above carboxylate ester bond-containing carboxylic acid derivative has a carboxylate ester bond and —COOM (M representing H, NH | 10-22-2009 |
| 20090306296 | CROSSLINKABLE POLYTETRAFLUOROETHYLENE COMPOSITION OF MATTER, POWDERED POLYTETRAFLUOROETHYLENE CROSSLINKED BODY, POLYTETRAFLUOROETHYLENE MOLDED BODY, RESIN BLEND COMPOSITION OF MATTER AND RESIN BLEND MOLDED BODY - The object of the present invention is to offer a PTFE resin that can be prepared by common molding methods such as compression molding and the like without the necessity for expensive equipment or hot coining methods or the like that are deleterious to productivity, and where harmful substances are not generated during manufacture, and convention strength, crystallinity and surface characteristics are preserved, and where there is neither anisotropy nor heterogeneity, and where the PTFE resin is more difficult to deform than is conventional PTFE resin. A crosslinkable polytetrafluoroethylene composition of matter contains polytetrafluoroethylene and a crosslinking agent. The polytetrafluoroethylene possesses at least one reactive functional group selected from the group consisting of cyano (—CN), carboxyl (—COOH), alkoxycarbonyl (—COOR (where R is a monovalent organic group)) and acid halide (—COX (where X is a halogen atom)) on at least one of the main chain and side chain terminal ends. The crosslinking agent reacts with one or a plurality of reactive functional groups and can form a cyclic structure. | 12-10-2009 |
| 20100130690 | METHOD FOR MOLDING POLYTETRAFLUOROETHYLENE, POLYTETRAFLUOROETHYLENE MOLDED BODY, CROSSLINKABLE POLYTETRAFLUOROETHYLENE, POWDERED POLYTETRAFLUOROETHYLENE CROSSLINKED BODY, RESIN BLEND COMPOSITION OF MATTER AND RESIN BLEND MOLDED BODY - A PTFE resin does not require the hot coining method and is more difficult to deform than conventional PTFE resins. A polytetrafluoroethylene molded body is obtained from a crosslinking polytetrafluoroethylene that possesses at least one type of reactive functional group selected from the group that comprises cyano group (—CN), a first functional group and a second functional group. The first functional group is represented by: | 05-27-2010 |
