DEFINITION

Classification: 493/933

Having multilayered wall:

(under subclass 916) Operation involving construction of a receptacle constructed so that a cross section through 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.
