Publication number: 20110079932Abstract: There are provided a foaming filler member which allows, even when the inner space of a hollow member has a protruding space, easy filling of the protruding space without using an extra member, a heat-foamable sheet used for the foaming filler member, a method for manufacturing the heat-foamable sheet, and a method for filling the inner space of the hollow member. A heat-foamable sheet which extends in one direction when heated at 100 to 130° C. for 20 minutes and has an extension ratio of 5 to 50% in the extension direction is manufactured by stretch-forming a heat-foamable material. Even when the inner space has the protruding space, the protruding space can be easily filled at low cost without using an extra member by using the heat-foamable sheet as the foaming filler member, disposing the foaming filler member in the main space of the inner space, and foaming it such that the extending direction of the heat-foamable sheet is oriented toward the protruding space.Type: ApplicationFiled: December 10, 2010Publication date: April 7, 2011Applicant: Nitto Denko CorporationInventors: Takehiro Ui, Yoshiaki Mitsuoka, Mitsuo Matsumoto

Patent number: 7819377Abstract: A foam filling member that can hold a foam sheet in a looped shape stably, without increasing the number of components, to provide improved vibration suppression and sound insulation. The strip-like foam sheet is formed in a looped shape by bending round it, so that both end portions of the foam sheet are overlapped with each other in a thickness direction thereof to form an overlapped portion therein. Then, insertion shafts of a clip are inserted through the overlapped portion, so that the overlapped portion is held in sandwich relation between a base portion and a head portion to form a foam filling member. Then, a supporting portion of the fixing portion of the clip is inserted in a fixing hole of an inner panel and fixed to the inner panel.Type: GrantFiled: November 30, 2005Date of Patent: October 26, 2010Assignee: Nitto Denko CorporationInventors: Kazuhiko Kinpara, Shinji Muto, Shinpei Nishikawa, Takehiro Ui
