.~> Insulating material between spaced wall panels
DEFINITION
Classification: 215/12.1
MULTILAYER BARRIER STRUCTURE:
(under the class definition) A receptacle wherein at least one of the walls includes substantially coextensive plural piles, laminas, layers, strata or panels.
(1) Note. Included here are spaced or contiguous piles, self-sustaining or nonself-sustaining layers, planar or nonplanar strata, free or secured laminas as well as solid, foraminous, particulate, gas, or liquid layers.
(2) Note. Included here as multilayer barrier structure is a receptacle with an internal or external "lining".
(3) Note. Generally, specific multilayer structure as defined above combined with a specific receptacle characteristic is considered classifiable in this and indented subclasses. However, mere "nominal" inclusion of a receptacle in such combination is not considered "specific"and, as such, is considered merely multilayer barrier structure, per se, for Class 428. See (1) Note of Class 206.
(4) Note. The stated utility of a receptacle multilayer barrier, e.g., reinforcement, insulation, partition "shock protection", etc., will not exclude a patent for such structure (otherwise meeting the above definition) from this or indented subclasses.
(5) Note. Multilayer structure limited to a seam or joint is not provided for here.
