DEFINITION

Classification: 4/526

Collapsible:

(under subclass 524) Subject matter in which the enclosure is capable of being folded compactly, with at least some of its constituent parts still connected together.

(1) Note. Merely because the enclosure could be dismantled into its constituent parts does not make the device the subject matter of this subclass.
