DEFINITION

Classification: 156/113

(under subclass 112) Processes in which the resilient material has apertures or enclosed cavities therein to increase the cushioning effect of the toroid.

(1) Note. The articles manufactured by these processes have no means for retaining fluids under compression. A disclosure that the article is a pneumatic pressure container is sufficient to keep it from this subclass.
