DEFINITION

Classification: 431/298

(under the class definition) Apparatus including a fibrous and flexible, cord, tape or tube; one end of which forms a flame holder; and that by capillary action draws up and feeds to the flame holder a steady supply of liquid fuel.

(1) Note. A claim to a wick by name only, in terms of material, but no structure peculiar to a wick is considered to be a claim to a sorbent for Class 502. Woven material is not considered peculiar to a wick but a specific weave is structure peculiar to a wick.
