Fluent material handling, with receiver or receiver coacting means

SECTION I - CLASS DEFINITION

GENERAL STATEMENT OF CLASS SUBJECT MATTER

This class provides for the transfer of fluent material, gaseous, liquid or flowable granular solids, through a flow confining system, the source and terminal or receiver parts of which are normally separable, i.e., one or both parts are portable or are otherwise capable of or intended to have a utility in their separated condition. Such utility ordinarily lies in portability of a separated part, either for use of the contents material in another place, or for use of one of the system parts with another complementary part. Each part therefore must comprise an entity capable of use independent of the other, and together the parts provide a flow path from a source or dispenser to a terminal part or receiver, thereby comprising a filling system.

This class takes a mere dispenser-receiver combination where separability is claimed or is inherent, and also takes means to deliver material to a receiver when there is claimed some system characteristic which peculiarly relates the receiver to the dispenser to define a coaction of one with the other to complete the dispenser-receiver relationship; as for example, guiding or confining means for the receiver, related conveying means for either the receiver or dispenser or both, or a receiver support which is not merely a support for the dispenser but is some member or modification beyond the structural requirements therefor.
