Abstract
Abstract A tray assembly for the delivery and service of foods, such assembly including base and cover sections having a plurality of opposing recesses for enclosing a number of dishes, cups, and other utensils needed for a complete meal service. Proper vertical alignment of the two sections as they are fitted together is facilitated by corresponding lateral indentations in the side walls of both parts which serve in manual guiding of the cover into position upon the base, and by arcuate shoulders spaced circumferentially about a generally central recess in one of the sections, such shoulders being received in a complementary channel in the other section. Lugs disposed within the channel are received in notches between the arcuate shoulders only when the cover and base sections are in precise rotational alignment. Should slight misalignment occur as the parts are being fitted together, the configuration and dimensions of the vessel-receiving recesses tend to re-orient the vessels without danger of spilling their contents.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
A food server combination comprising separable tray and cover sections; said tray and cover sections each having planar body portions and having front, rear, and side walls; said planar body portion of said tray section having a plurality of upwardly-opening recesses for receiving dishes, cups, and the like; one of said recesses being generally centrally disposed intermediate the side walls of said tray section; said planar body portion of said cover section having a plurality of downwardly-opening recesses complementing the recesses of said tray section and including a generally central recess overlying the central recess of said tray section; one of said sections providing a channel extending perimetrically about the central recess thereof and the other of said sections providing a plurality of arcuate circumferentially-spaced shoulders received within said channel; said one section also including a plurality of lug portions in said channel received in the spaces between said circumferentially-spaced shoulders and engagable with the ends of said shoulders for locking said cover and tray sections against relative rotation in planes parallel with said planar body portions.
Claim 2
Dependent Claim
177 words
A food server combination comprising separable tray and cover sections; said tray and cover sections each having planar body portions and having front, rear, and side walls; said planar body portion of said tray section having a plurality of upwardly-opening recesses for receiving dishes, cups, and the like; one of said recesses being generally centrally disposed intermediate the side walls of said tray section; said planar body portion of said cover section having a plurality of downwardly-opening recesses complementing the recesses of said tray section and including a generally central recess overlying the central recess of said tray section; one of said sections providing a channel extending perimetrically about the central recess thereof and the other of said sections providing a plurality of arcuate circumferentially-spaced shoulders received within said channel; said one section also including a plurality of lug portions in said channel received in the spaces between said circumferentially-spaced shoulders and engagable with the ends of said shoulders for locking said cover and tray sections against relative rotation in planes parallel with said planar body portions.

Claim 4
Dependent Claim
46 words
