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:
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.
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.
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.
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.
