1. An apparatus for carrying and storing matter in a desired ambient temperature, the apparatus comprising:
a circular primary tray structure, the circular primary tray structure comprising a circular inner support platform portion and a circular outer shroud-receiving portion, the circular inner support platform portion having a support surface and a peripherally-located matter-receiving depression, the support surface being at a first elevation, the matter-receiving depression being at a second elevation lower than the first elevation, the circular outer shroud-receiving portion having a peripherally-located, dual-groove, shroud-junction construction, the peripherally-located, dual-groove, shroud-junction construction being in radially outer adjacency to the matter-receiving depression and having a circular, radially inner groove and a circular, radially outer groove, the radially inner groove having an inner groove trough and the radially outer groove having an outer groove trough, the inner groove trough being at a third elevation and the outer groove trough being at a fourth elevation, the third elevation being lower than the second elevation and the fourth elevation being lower than the third elevation, the (1) matter-receiving depression, (2) inner groove trough and (3) outer groove trough thus forming a stepped, peripherally-located, series of platform-based depressions relative to the first elevation of the support surface; a circular shroud structure, the circular shroud structure comprising an inner cover portion, and an outer wall portion contiguous with the inner cover portion, the inner cover portion defining a primary matter-receiving space for covering matter supported by the support platform portion, the outer wall portion and the inner cover portion defining a medium-receiving space, the medium-receiving space for receiving and positioning a heat transfer medium adjacent the primary matter-receiving space, the primary matter-receiving space being separated from the medium-receiving space via the inner cover portion, the outer wall portion having a peripherally-located, dual-ridge, platform junction construction, the peripherally-located, dual-ridge, platform-junction construction having a circular, radially inner ridge and a circular, radially outer ridge at a bottom portion thereof, the radially inner ridge being elevated relative to the radially outer ridge, the radially inner and outer groove troughs for respectively receiving the radially inner and outer ridges; a lid structure, the lid structure being seatable upon the shroud structure for covering the medium-receiving space; and fastening means for removably fastening the primary tray structure to the shroud structure, a heat transfer medium being receivable in the medium-receiving space for effecting heat transfer intermediate the medium-receiving and primary matter-receiving spaces for maintaining matter received within the primary matter-receiving space in a desired ambient temperature. |
