appropriate container class).
SCOPE OF THE CLASS
Class 402 is intended as the locus for devices and subcombination
thereof the proximate function of which is the retention of sheets* by
sheet retainer* means which passes through the thickness
dimension* of the sheets to releasably retain the sheets.
The subject matter for the most part represents what is generally
known as the loose-leaf binder "art".
STRUCTURE OF THE CLASS
The first-line subclasses of the class are based on the mode
of operation of the sheet retainer*, where possible, with
the remainder of the subclasses based on the structure (generally
static) of the device.
Provided in this class are cross-reference art collections
based on disclosed use or particular characteristics as indicated
in the titles and definitions thereof. These collections of disclosures
are not exhaustive but are intended as aids to a search based on ultimate
function or use, as a supplement to a search of other subclasses
in this class, or as an indication of further related fields of search
inside or outside this class.

This subclass is indented under subclass 73. A depository which includes a first sheet-like member (i.e., "face" member),
which is to be disposed along a nonthickness surface* of
the sheet, in combination with a second sheet-like member (i.e., "back" member)
which is to be disposed adjacent a thickness dimension (see Fig.
1 of Glossary) of the sheet.
(1)
Note. The face member and back member may constitute a continuous
piece of single or plural layer material.
(2)
Note. A back member, per se, will be placed in subclass 73
whereas a member or members which are disposed along a thickness
surface (see Fig. 1 of Glossary) and at least a portion of a nonthickness surface
(see Fig. 1 of Glossary) will be placed in this or an indented subclass.
This subclass is indented under subclass 74. Depository wherein the second member includes two portions
thereof interconnected by a pliant or rotatable means which permit rotation
of one portion relative to the other.
and especially subclasses 42+ for a sheet
retainer requiring arcuate travel thereof in a plane perpendicular
to its axis of rotation for sheet removal in combination with a
depository which may have a back member including hinged portions.
This subclass is indented under subclass 74. Depository wherein the face and back members are interconnected
adjacent marginal portions by a pliant or rotatable means.
This subclass is indented under subclass 73. A depository having a member which serves to partially cover
or underlie only a nonthickness surface of a sheet or group of sheets
to be associated therewith.

fibrous product, or (2) a plural-layer product including a layer
of fibers applied to a second layer by a process provided for in
that class (162); and particularly
subclasses 141 through 181.1,which include any nonstructural fiber (or fiber-containing)
product (e.g., a particular blend of fibers) regardless of whether

aperture or notch in the tab, continuous strip, or other attachment
means to releasably secure the sheet by disengagement from the notch
or aperture.
(1)

may be disclosed as securing a notched sheet but the structure of
which does not meet the definition of this subclass will be placed
in an appropriate subclass above.
for a similar device including a like sheet retainer
