ABSTRACT:
A proofer container for use in the baking industry fabricated of high-density material exhibiting substantial imperviousness to environmental contaminants. A unitary structure is provided with a suitably shaped dough-receiving receptacle and is configured to receive and contain a quantity of dough to be proofed, or raised in an intermediate step in the production of baked products. The unitary structure may be provided by use of a typical rotomolding process that is further enhanced by the insertion of a pin extending through an end wall of the mold and extending into the mold cavity to an adjacent section to a location so that the interior of the pin is spaced from the adjacent section by a distance substantially equal to the thickness of the walls of the tray to be fabricated. This step in the molding process provides a receptacle for a mounting pin or axle that is structurally sound and insures that the proofer tray has a continuous surface that is impervious to the entry of foreign contaminants to the interior of the hollow tray. The article produced according to this process provides features set forth above.
