(under the class definition) Apparatus combined with means for subjecting the contents material, either before, after or during packaging, to an agency which alters a physical or chemical characteristic of the contents material or which prevents a constituent of the ambient atmosphere, or another
ambient condition from altering a physical or chemical characteristic of the contents material.
(1) Note. Other main classes appropriate to the type of treatment must be searched in addition to those listed hereunder as search classes.
(2) Note. Mere change of position of separate contents parts relative to one another, as by accumulating separate contents units into a group, or flowing fluent material into a receptacle, such as a contents charge holding chamber, is not regarded as treating the contents to change a physical property. Group forming of contents units combined with subsequent or further packaging is included in this class (53) in subclasses 147+. Apparatus having a contents charge holding chamber is not set out separately in this class (53), but may appear in any subclass.
(3) Note. This subclass includes apparatus having means to emboss a design or lettering upon the contents. See subclasses 113+ indented hereunder for apparatus having means to reshape the contents particularly subclass 122 for molding or plastic deformation.
