Title: Plastic foamed composite
Inventor: SHIINA TADAAKI
IPC: B32B5/18
Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a foamed material has excellent heat insulating properties but absorbs water upon the contact with water to be lowered in its heat insulating properties and, if pressure is applied to the foamed material, the foamed material is deformed to become thin and increased in its density to be lowered in heat insulating properties. SOLUTION: A plastic box absorbing no moisture is demarcated by reinforcing members combined so as to become parallel and right-angled to side surfaces and respective chambers surrounded by the reinforcing members are closely filled with the foamed material and a lid is welded to the box to form the composite. This composite does not generate the lowering of heat insulating properties due to water absorption and, since the foamed material is prevented from becoming thin by compression and not increased in density, it is extremely good as a heat insulating material and can be used over a long period of time. Further, this composite is preferable as a cushioning material, a shock absorber, a floating material or the like.
