DEFINITION

Classification: 493/906

Having multilayer wall:

(under subclass 901) Operation involving the construction of a receptacle constructed so that a cross section through the wall would yield multiple, distinct (i.e., not completely bonded together) sheets of material.

(1) Note. Folding of flaps over the wall would yield multiple layers of material, but such construction is not intended to be placed in this subclass.
