DEFINITION

Classification: 222/565

(under the class definition) Dispensers in which the only dispensing feature claimed, pertains to the sifter or sprinkler or other plural opening patter form outlet.

(1) Note. An outlet of plural opening pattern form may be of any foraminous nature and need not be for sifting or sprinkling purpose.

(2) Note. Since the type of outlet provided for in this subclass has been treated as a single outlet, patents having this type of outlet appear in numerous preceding subclasses which provide for special characteristics or combinations of which this type opening may be a part. For the line between this type of opening and the plural openings of subclasses 478+, see the notes to subclass 478. Some of the preceding subclasses will be separately noted below.
