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.

The scope of this class does not include method and apparatus for handling fluent material except in a manner characteristic of fluid flow. For the most part the material supply processes and apparatus involve discharge assistants and fluid flow guiding means of the class of Dispensing (see References to Other Classes, below).

This class takes systems as above defined including receivers which close (i.e., self-closing) upon separation or uncoupling from the supply.

This class also includes processes of varying gaseous conditions in a vessel or container, i.e., evacuating or maintaining a vacuum in a container, by sorption or gettering means incased in such container where the claims are silent respecting any sealing off, or do not include steps of closing and additionally where the sorption or gettering is not of the kind provided for elsewhere.

This class also includes certain combinations and subcombinations which appear to fall short of the receiver coacting means requirement set out above, as in the last four "first line" subclass groups of this class. Though they require no more than what might be considered to be Class 222 subject matter, the concept of a normally detached, readily connectable, dispenser-receiver relation (see I (2) above) is satisfied.

Lines with other classes and within this class

COMBINATIONS OF FILLING APPARATUS WITH TREATING OR MANUFACTURING APPARATUS

As between this class (141) and Class 53, Package Making, Class 53 takes methods of and apparatus for packaging where some manufacturing operation as to either the package or its contents material is included anywhere along the line.

Class 53 includes among other packaging inventions the following:

Chemical packaging:

The selection of materials for cover and/or lining compatible with chemical or reactive contents material for package making is considered a type of manufacture, and is included in Class 53.

Article packaging:

Methods of packaging articles and apparatus for packaging articles not however those which rely upon fluid-flow handling methods or apparatus.

Contents treating and packaging:

Methods of and apparatus for packaging with or without closing if the contents material is treated or prepared by processes or apparatus involving an irreversible operation more commonly known as manufacture.

Filling with fluent material:

Filling with fluent materials where an arrangement not obtainable by fluent material flow results. Mere compacting is not included, but the packaging of a compacted charge which is subsequently handled as an article is, and also compacting to produce a package of a definite predetermined shape.

Receiver or cover making and filling:

Methods of and apparatus for forming a cover or receiver and filling with fluent material or articles with or without closing including opening the receiver, e.g., a collapsed bag, or any covered receiver. Opening self-closing type receivers and filling with fluents is excepted. See I above.

Receiver filling and closing:

Methods of and apparatus for filling receivers with articles and/or fluent materials and closing such receivers.

Receiver filling:

Filling apparatus including additional means claimed in combination therewith having utility only in a closing or closure applying or associating function is included in Class 53, for example, relative to "jetting", such structure for supporting closure means and moving same through a jetting stream or the like with an associated filled receiver even though the step of or means for depositing the closure on the receiver is omitted, or receiver spacing or holding means after filling for cover application or a closing operation without applying the closure or closing.

TREATMENT CLASSES

As to the treatment classes, the line is whether or not there is present some handling operation other than supplying material to or removing it from the treatment area or chamber. Those patents which claim more than the handling incidental to treatment are placed in the appropriate material handling class, including this one, as they are also in many instances where the treatment device is claimed by name only, with incidental handling means and no other.
