Abstract
Abstract A dish drainer is provided having a base structure and sidewalls integrally hinged therewith. The sidewalls are fabricated in the 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
203 words
A dish drainer formed from a thermosetting synthetic resin comprising; a base adapted for positioning on a supporting surface and having at least two adjacent peripheral side edges, said base formed with a plurality of open-topped elongated slots for receiving edge portions of dishes, at least two sidewalls with each sidewall disposed at a respective side edge of said base, each sidewall interconnected at one edge thereof with the respective peripheral side edge of said base, one of said sidewalls formed with said base along a peripheral side edge disposed transversely to the longitudinal aXis of said elongated slots, said last mentioned sidewall having a plurality of upstanding ribs formed in spaced parallel relationship on the inwardly facing surface thereof with the space between adjacent pairs of said ribs disposed in longitudinal alignment with a respective one of said slots, hinge means integrally formed with said base and each of said sidewalls permitting relative swinging movement about a hinge axis parallel to the adjacent interconnected edges between a position in the plane of said base and a position upright thereto, and fastening means cooperatively interengaging each of said adjacent sidewalls when said sidewalls are disposed in upright relationship to secure said sidewalls together.
Claim 2
Dependent Claim
203 words
A dish drainer formed from a thermosetting synthetic resin comprising; a base adapted for positioning on a supporting surface and having at least two adjacent peripheral side edges, said base formed with a plurality of open-topped elongated slots for receiving edge portions of dishes, at least two sidewalls with each sidewall disposed at a respective side edge of said base, each sidewall interconnected at one edge thereof with the respective peripheral side edge of said base, one of said sidewalls formed with said base along a peripheral side edge disposed transversely to the longitudinal aXis of said elongated slots, said last mentioned sidewall having a plurality of upstanding ribs formed in spaced parallel relationship on the inwardly facing surface thereof with the space between adjacent pairs of said ribs disposed in longitudinal alignment with a respective one of said slots, hinge means integrally formed with said base and each of said sidewalls permitting relative swinging movement about a hinge axis parallel to the adjacent interconnected edges between a position in the plane of said base and a position upright thereto, and fastening means cooperatively interengaging each of said adjacent sidewalls when said sidewalls are disposed in upright relationship to secure said sidewalls together.
Claim 3
Dependent Claim
48 words
A dish drainer according to claim 1 wherein said fastening means includes a laterally projecting tab extending from each end of each side wall in the plane of said sidewall and a fastener device interengageable with two of said tabs when said sidewalls are disposed in upright relationship.
Claim 4
Dependent Claim
50 words
A dish drainer according to claim 2 wherein each of said tabs has a through aperture formed therein which is aligned with the aperture in the overlapping tab of an adjacent sidewall when said sidewalls are disposed in upright relationship, and said fastener device is insertable through the aligned apertures.
Claim 5
Dependent Claim
17 words
A dish drainer according to claim 2 wherein said fastener device is removably interengageable with said tabs.
Claim 6
Dependent Claim
36 words

Claim 7
Dependent Claim
33 words
A dish drainer according to claim 5 wherein said hinge means comprises a plurality of relatively short elements formed at the juncture of each sidewall and respective peripheral side edge of said base.
Claim 8
Dependent Claim
21 words
A dish drainer according to claim 1 wherein each sidewall has a reinforcing bead formed therewith along the unhinged longitudinal edge.
Claim 9
Dependent Claim
25 words
A dish drainer according to claim 1 wherein elongated slots are formed in said last mentioned sidewall intermediately of at least some of said ribs.
Claim 10
Dependent Claim
30 words
A dish drainer according to claim 1 wherein said base is provided with at least one closed bottom, open topped recess disposed adjacent one peripheral side edge of said base.
Claim 11
Dependent Claim
17 words
