plane of the base structure for facilitation of transport and
storage but are pivoted to a relatively upright position to the
base structure for utilization as a dish drainer. End portions of
adjacent sidewalls are interengageable to secure the sidewalls in
the upright position but may be disengaged for subsequent storage
in a flat configuration. Suitable fastener devices are provided for
securing the adjacent sidewalls in interengaged relationship.
Recesses are formed in the base structure for maintenance of
flatware in upstanding relation to a cooperative sidewall with slot
and rib conformations formed in the base structure and another
cooperative sidewall for vertical positioning of plates or
dishes.

Description
BACKGROUND OF THE INVENTION
Dish drainers heretofore devised generally comprise a rigid
plastic-coated wire-frame or plastic structure that is fabricated
as an open-top container. The sidewalls of such structures are
integrally formed with the adjacent sidewalls as well as the base
structure thereby resulting in a drainer having a substantial
depth. Also, dish drainers of this prior art construction are
formed with various conformations adapted to vertically support
plates or other substantially flat dishes in an upright
position.
A structure thus unitarily fabricated presents the associated
problem of bulk in storage and transportation. Transportation costs
materially affect sales price and are a substantial economic
factor. Similarly, storage of bulky articles further increases
costs and the ultimate sales price. Also as a direct consequence of
their bulk, the prior art structures require a substantial amount
of store display space.
SUMMARY OF THE INVENTION
In accordance with this invention, a dish drainer is provided which
is fabricated in a relatively thin, planar configuration. This is
accomplished by molding the structure from a suitable thermoplastic
synthetic resin, polymerized propylene for example, with the
sidewalls being interconnected with the base by an integrally
molded hinge. Thus the sidewalls which are initially formed in the
same plane as the base may be subsequently folded upwardly to form
the upstanding sides of the dish drainer. The ends of the sidewalls
are provided with tabs which cooperatively interconnect with a
similar tab on an adjacent sidewall and are releasably therewith by
a fastener device.
A plurality of parallel slots are formed in the base to receive a
segmental edge portion of plates which are thereby maintained in a
vertical plane for draining. One of the sidewalls is also formed
with a plurality of slots longitudinally aligned with those in the
base and is preferably provided with a corresponding number of
upstanding ribs disposed parallel to and intermediate the slots.
With this sidewall positioned upright, the slots and ribs also
cooperatively engage any plates vertically positioned in the slots
of the base thereby aiding in their support. Several closedbottom
recesses may be formed in the base along one side thereof to
receive and retain the ends of vertically disposed flatware which
also rest against the adjacent inclined sidewall.
Fabrication of this dish drainer with integrally hinged sidewalls
results in a structure that requires a minimum of space for storage
or transport. The flat planar configuration is also particularly
beneficial in merchandising as displays may be neatly arranged and
easily maintained with full stock for enhancement of sales
appeal.
These and other objects and advantages of this invention will be
readily apparent from the following detailed description of an
embodiment thereof and the accompanying illustrative drawings
thereof.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENT
A dish drainer 10 embodying this invention is shown in FIG. 1 as it
appears when assembled for utilization in its intended functional
role. The drainer 10 comprises a base 11 and four sidewalls 12
which are hinged to the base. It will be noted that the sidewalls
12 in this assembled configuration are disposed in a substantially
vertical position but are inclined slightly outward. Fastening
means 13 formed with the sidewalls cooperatively interengage to
maintain the sidewalls in rigidly interconnected upright
relationship.
The base 11 of the illustrative embodiment is square in plan view
having a respective sidewall 12 interconnected to the base at each
of four peripheral side edges 14 of predetermined depth. Forming
the interior area of the base are a plurality of vertical ribs 15
disposed in spaced parallel relationship to each other and
extending across the base to opposed peripheral side edges 14. A
cross rib 16 also vertically oriented extends laterally of the ribs
15 at their approximate midpoint and, in this integrally molded
construction interconnects with each longitudinal rib. These ribs
define open top and bottom slots into which plates (not shown) may
be vertically positioned for drainage. The length of the sockets is
controlled by the cross rib 16 to a dimension which preferably does
not permit the plates to fully project through the slots and extend
below the bottom surface of the base in accordance with the depth
of the base. Formed with each of two opposed peripheral side edges
are two spaced apart, and downwardly extending projections forming
feet 17 to maintain the base relatively elevated and permit
drainage from under the side edges 14.
Also formed in the base 10 are three closed bottom recesses 18.
These recesses 18 are arranged in longitudinal alignment along one
peripheral side edge 14 of the base and parallel to the
longitudinal ribs 15. Two longitudinally spaced divider ribs 19 are
preferably equidistantly spaced to define uniform length recesses
and the bottom wall 20 of each is provided with two drain holes 21.
Flatware such as knives, forks and spoons (not shown) may be
vertically positioned in the recesses 18 and rested against the
inclined surface of the adjacent sidewall 12 for draining. Water
collected in the recesses drains through the drain holes 21.
Each of the sidewalls 12 is of the same general configuration
consisting of a rectangularly shaped, relatively thin sheet of
material with the length of each being the same as that of the
peripheral side edge 14 of the base to which it is connected.
Formed with each sidewall at each end thereof adjacent the free
longitudinal edge are longitudinally extending tabs 22 forming
cooperative portions of the fastening means 13. The tabs are each
provided with a circular aperture 23 through which a fastener
device 24 is inserted to interconnect two adjacent sidewalls in
assembled relationship. It will be noted in the several figures of
the drawings that the tabs of adjacent sidewalls overlap in
assembled relationship with the respective apertures 23 aligned to
cooperatively receive one of the fastener devices 24 for
interlocking of the sidewalls. Also, the sidewalls are preferably
at an angle of the order of 80.degree.-85.degree. to the horizontal
when assembled.
All of the sidewalls 12 are interconnected with the base 11 by
hinge means 25 comprising integrally formed portions of the same
plastic material as the base and sidewalls. The plastic material
selected is polymerized propylene, a synthetic thermoplastic resin,
that exhibits the desired characteristics of extreme flexibility
when formed in relatively thin sections. Such material as is well
known exhibits a substantial degree of rigidity when formed in
thicker sections as in the case of the base and sidewalls. To
further enhance flexibility and hinged movement of the sidewalls,
the hinge means relative to each side is formed as four relatively
short sections that are designated by the numeral 25 and define
three intervening open spaces.
Each of the sidewalls 12 is also provided with an enlarged bead 26
formed along the free longitudinal edge. This bead 26 does not
extend onto the tabs 22 and is operative to increase the rigidity
of the sidewalls without resort to increase of wall thickness.
Limiting the bead 26 to the main rectangular section of the
sidewall enables the tabs 22 to be readily bent at the corners into
overlapping relationship with the tab of an adjacent sidewall
during an assembly operation.
One of the sidewalls 12 at the longitudinal ends of the ribs 15 is
provided with a plurality of ribs 27 disposed in spaced parallel
relationship. These ribs 27 are formed on the upper or inner
surface of the sidewall and are arranged in longitudinal alignment
with respective ones of the longitudinal base ribs 15. An elongated
opening 28 is formed in the sidewall between adjacent pairs of the
ribs 27 with the elongated openings being slightly less than that
of the ribs. These openings and ribs cooperate with the base ribs
and slots to maintain the larger size plates upright in the
drainer. Preferably, this sidewall is not provided with an
elongated opening between the last pair of ribs 27 as seen at the
right of FIG. 1 for enhancement of the sidewalls' rigidity.
A fastener device 24 particularly suitable for securing the
overlapped tabs 22 is shown in detail in FIG. 4. This fastener
device is also formed from a propylene polymer and comprises a flat
circular head 29 and integrally formed shank 30. The shank 30 is a
flat, diamond shape provided with a central aperture 31. While the
widest dimension of the shank 30 is greater than the circular
aperture 23 in the tabs 22, the inherent flexibility of the
material coupled with the aperatured configuration enables the
shank to collapse to an extent permitting insertion through the tab
aperture. If desired, the fastener devices may be removed to permit
return of the sidewalls 12 to the plane of the base 11.
It will be readily apparent from the foregoing detailed description
of the illustrative embodiment, a novel dish drainer is provided
which may be advantageously fabricated in a flat, planar
configuration. This configuration effects economy in transportation
and storage as well as in fabrication. The drainer is readily
assembled in the desired configuration with upright sidewalls by
means of the friction-locking fastener devices.
