A substrate tray for accommodating at least one ceramic substrate therein including: an accommodation part including a first opening part of which the upper side is open so that the ceramic substrate can be accommodated and withdrawn; and a support part formed on the circumference of the accommodation part so as to support the side wall circumference of the ceramic substrate, wherein the support part includes: an inner wall in contact with at least one surface of the ceramic substrate; an outer wall spaced a predetermined distance from the inner wall; an upper surface for connecting the inner wall to the outer wall; and a second opening part formed to be open in the direction opposite to the first opening part at a location facing the upper surface between the inner wall and the outer wall.

A meat tray sized and shaped to support raw meat is provided. The meat tray is composed of a paperboard material. The meat tray may include a generally planar base extending to a sidewall that extends transversely from the planar base to an angled outer transition which forms an outer periphery of a tray cavity. A rim of the meat tray is located at a terminus of the angled outer transition and extends away from the cavity. The rim may include an outer arcuate rim portion that extends and curves away from the outer transition and a planar flange extending from the outer arcuate rim portion and terminates at an edge. The edge faces downwardly with respect to the outer arcuate rim portion.

A repositioning and retaining device for a mail delivery tray is provided. The device includes a central body to receive at least one mailpiece thereagainst. The central body defines a substantially planar surface. The device also includes at least one intermediate portion operatively connected and arranged substantially perpendicular to the central body. The at least one intermediate portion provides a lateral boundary for the at least one mailpiece. The device further includes at least one peripheral guide extending outward from and in a direction transverse to the central body and operatively connected to the at least one intermediate portion. The at least one peripheral guide engages with a sidewall of the tray to orient and removably secure the device to the tray. A system for repositioning and retaining mail and a method of using the repositioning and retaining device for a mail delivery tray are also provided.
