DEFINITION

Classification: 426/77

(under the class definition) Subject matter involving foraminous infusion receptacles or packages containing an infusible charge therein such as tea leaves, ground coffee, etc.., and which is usually of the single use type.

(1) Note. A number of patents have been placed in this and the indented subclasses which do not positively recite the combination of an infusible charge and infusor. These

patents, however, are of the type which would require the destruction of the infusor, as in an infusor package in order to incorporate an infusible charge therein, and for classification purposes these patents have been interpreted as calling for the defined combination.

(2) Note. The line between this subclass and the indents thereunder and Class 99, Foods and Beverages: Apparatus, subclass 295, is that this class (Foods) will take the subcombination of a disposable infusor with a charge therein while Class 99, subclass 295, will take the subject matter defined above in combination with an infusor apparatus.
