Icon_funbox Did You Know...

...that while attempting to develop a super strong glue, 3M employee Spencer Silver accidentally developed a glue that was so weak it would barely hold two pieces of paper together? However, his colleague Art Fry needed the glue. Fry sang with his church choir and marked the pages of his hymnal with small scraps of paper that often fell out. He used Silver's glue to hold the papers in place. Today we call this invention Post-it Notes.

Subclasses list

Definition

This is the residual class of closures, which are movable or removable, and of ancillary devices not elsewhere classifiable.

Notes

(1) Note. The terms "closure", "movable closure", and "removable closure", are defined in the glossary. (2) Note. The schedule of this class was built on patents issued since 1930. Older patents were placed in the schedule mainly on the basis of disclosure and not necessarily on the basis of claimed subject matter.

Lines with other classes and within this class

Class 49 is superior to Class 160 and will take a flexible closure panel under the following conditions:

(1) An impact absorbing flexible barricade as set forth in Class 49, subclass 9.

(2) A flexible movable closure combined with an animal blocker, repeller or chaser. See Class 49, subclasses 58+.

(3) Plural flexible movable closures on opposite sides of an independently movable or removable center post. See Class 49, subclass 365.

(4) When the closure does not depend upon its flexibility for movement, e.g., a flexible panel within a rigid frame which is mounted for movement, and is not provided for in the Class 160 schedule.

See 445, for the line between the counterbalances in this subclass and the counterbalances in the class for Miscellaneous Hardware

(A) Certain classes take closure combinations where only so much of the closure is claimed as pertains to the subject matter of the class noted. See Class 16, subclass 193, and Class 49, subclass 445, for the lines between the counterbalances in the two subclasses. Also see References to Other Classes, below, for specific Class citations.

(B) Certain classes take a closure claimed as the load by name only or in general terms. See References to Other Classes, below, for specific Class citations.

CLOSURES IN OTHER CLASSES

(A) Art devices having a closure as a part of the combination are classified for the most part with the particular art. The following notes mention some such art combinations, but no attempt has been made to mention all. An attempt has, however, been made to list all classes and subclasses for closures, per se.

(B) Dispensing

Closures constructed for dispensing, specially related to receptacles or containers to assist to promote dispensing, or combined with other dispensing structure have (for the most part) not been listed. In some instances, dispensing structures and/or closures having structure closely related to nondispensing closure structures, have been listed. For such devices, see the appropriate dispensing classification, Class 222, Dispensing, being the generic class, and see the notes in that class for the distribution of dispensing art.

(C) Valves

Valve type closures are not here listed; see References to Other Classes, below, for specific citations to the main classes for valves.

(D) Other categories of closures in References To Other Classes include:

Firearms, Ordnance and Ammunition;

Furnace and Heating Classes;

Receptacle, Building Structure and Vehicle Body Classes; and

Miscellaneous classes, not above mentioned, that have closures combined with other things, closures, per se, devices used with closures and devices not used as closures but having analogous structure, considered worth noting.
