(11) FIG. 1A depicts a tray cover 100, according to an embodiment of the invention. Tray cover 100 may include a substantially flat covering portion 130 that is disposed between two flange portions 120. Covering portion 130 may be substantially rectangular in cross-section. As depicted in FIG. 1C, flange portions 120 may be substantially perpendicular to covering portion 130. Flange portions 120 may extend upwardly from covering portion 130. Covering portion 130 may be configured to cover a holding tray 400 (see FIG. 4). For example, the length and width of covering portion 130 corresponds to the size of holding tray 400. In alternative embodiments, tray cover 100 may have perforations formed therein as a vent 140 (shown schematically in FIG. 1A), which may allow some air communication between the inside of holding tray 400 and ambient atmosphere, such that some moisture may be allowed to escape holding tray 400, in order to regulate humidity of holding tray 400.

(12) A channel 110 may be formed in each of the flange portions 120. As depicted in FIG. 1B, channel 110 may have a first portion 112 that extends from the edge of the flange portions 120. First portion 112 may extend substantially vertically, for example, substantially perpendicular to the edge of flange portions 120. A second portion 114 may extend from first portion 112 and may join a supporting portion 116, such that second portion 114 is disposed between first portion 112 and supporting portion 116. Second portion 114 may extend substantially horizontally. Supporting portion 116 may be substantially parallel to first portion 112. Supporting portion 116 may be substantially perpendicular to second portion 114. Second portion 114 may meet first portion 112 with a curved portion formed therebetween. Supporting portion 116 may meet second portion 114 with a corner formed therebetween. Alternatively, the curved portion may be a corner and/or the corner may be a curved portion. Thus, channel 110 may be substantially J-shaped or substantially U-shaped. Supporting portion 116 may be disposed at substantially the center of tray cover 100 in the width direction.

(13) FIG. 2 depicts a front view of tray cover 100, according to an embodiment of the invention. Tray cover 100 may be a unitary piece with flange portions 120 bent upward from covering portion 130. Alternatively, flange portions 120 may be formed separately from covering portion 130.

(14) FIG. 3 depicts a front view of tray cover 100 being installed in a holding apparatus 300, according to an embodiment of the invention. A projecting portion 310 may be disposed on a surface of holding apparatus 300, above a cabinet portion 320. Projecting portion 310 may be a pin, a knob, a peg, a cylinder, or the like, that is fixed to a surface of holding apparatus 300 or formed integrally with the surface. The width of channel 110 may correspond to the width of projecting portion 310. Tray cover 100 may be installed in cabinet portion 320 by inserting tray cover 100 such that projecting portion 310 is coupled to channel 110 by entering first portion 112 of channel 110. Tray cover 100 may continue to be moved, such that projecting portion 310 moves along channel 110, from first portion 112 to second portion 114, and then to supporting portion 116.

(15) For example, tray cover 100 may be moved substantially vertically upward such that projecting portion 310 enters channel 110 via first portion 112. Tray cover 100 may then be moved substantially horizontally such that projecting portion 310 moves along second portion 114 of channel 110. Tray cover 100 may be set and held in place, as projecting portion 310 moves into supporting portion 116 of channel 110 via substantially vertical movement of tray cover 100. When tray cover 100 is installed, as depicted in FIG. 4, projecting portion 310 may contact a supporting edge of supporting portion 116 such that supporting portion 116 supports tray cover 100 in place via projecting portion 310. The supporting edge may be shaped to correspond to the shape of projection portion 310. Projecting portion 310 may be disposed on each of front and back walls of holding apparatus 300, to correspond to channels 110 formed in each of flange portions 120.

(16) As depicted in FIG. 4, holding tray 400 may be inserted in cabinet portion 320 below tray cover 100. Holding tray 400 may be slidably installed in cabinet portion 320. Holding tray 400 may have a lip or rim forming an edge 410 along the upper perimeter of holding tray 400. As holding tray 400 is installed, edge 410 may make sliding contact with tray cover 100. Alternatively, edge 410 may be slightly separated from tray cover 100 such that a small gap is formed therebetween. In alternative embodiments, tray cover 100 may have grooves that engage with edge 410 of holding tray 400. In other alternative embodiments, tray cover 100 may have substantially vertical flanges that extend downward from the side edge of tray cover 100 to engage with or be disposed adjacent to edge 410 of holding tray 400.

(17) FIG. 5 depicts a perspective view of tray cover 100 installed in cabinet portion 320, according to an embodiment of the invention. When installed, tray cover 100 may be suspended in cabinet portion 320 via projecting portions 310 contacting supporting portions 116 of channels 110 formed in flange portions 120. Tray cover 100 may rest in place with projecting portions 310 in contact with supporting portions 116 via gravity, such that tray cover 100 is thereby hanging on holding apparatus 300 via projecting portions 310 disposed on front and rear faces of holding apparatus 300. Thus, tray cover 100 may be disposed in an upper portion of cabinet portion 320 with a space below tray cover 100 for holding tray 400 to be inserted. In addition, flange portions 120 may be adjacent to the surfaces of holding apparatus 300 on which projecting portions 310 are disposed.

(18) As depicted in FIG. 6, when holding tray 400 is installed in cabinet portion 320, tray cover 100 is configured to cover holding tray 400. For example, tray cover 100 may extend beyond the perimeter of holding tray 400. Edge 410 of holding tray 400 may be in contact with covering portion 130 of tray cover 100 around the entire perimeter of holding tray 400. Thus, tray cover 100 may contain moisture inside of holding tray 400 by creating a barrier between the inside of holding tray 400 and ambient atmosphere. Cabinet portion 320 may be heated and food product may be held in holding tray 400 and inserted in cabinet portion 320 for a holding period of time. Tray cover 100 may contain moisture in holding tray 400 while it is in cabinet portion 320 for the holding period, reducing the drying out of food product.

(19) Further, tray cover 100 is configured such that holding tray 400 may be inserted and removed from cabinet portion 320 from either side, i.e., a pass-through system. Holding tray 400 may be slid in and out of cabinet portion 320 to expose access to food product held in holding tray 400 without the use of tools or additional user action. In other words, because tray cover 100 is suspended in place via projecting portions 310 and supporting portions 116 of channels 110, a user may gain access to food product held in holding tray 400 simply by sliding out holding tray 400 from cabinet portion 320, without having to remove a cover or lid. In addition, because tray cover 100 is easily attached and removed without the need for tools, tray cover 100 may be easily washed by hand or by a dishwasher.

(20) In alternative embodiments, tray cover 100 may include a plurality of channels 110 to correspond to a plurality of projecting portions 310 from which tray cover 100 may be suspended. Further, in alternative embodiments, tray cover 100 may be formed in a variety of different shapes and sizes to correspond to different shapes and sizes of holding trays. Moreover, in alternative embodiments described above, tray cover 100 may have perforations formed therein as a vent 140 (shown schematically in FIG. 1A), which may allow some air communication between the inside of holding tray 400 and ambient atmosphere, such that some moisture may be allowed to escape holding tray 400, in order to regulate humidity of holding tray 400.

(21) While the invention has been described in connection with preferred embodiments, it will be understood by those of ordinary skill in the art that other variations and modifications of the preferred embodiments described above may be made without departing from the scope of the invention. Other embodiments will be apparent to those of ordinary skill in the art from a consideration of the specification or practice of the invention disclosed herein. The specification and the described examples are considered as exemplary only, with the true scope and spirit of the invention indicated by the following claims.
