Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
208 words
A lightweight, longitudinally elongated, hollow proofer tray comprising in combination; a longitudinally elongated hollow housing having top bottom and end walls formed of a continuous layer of material impervious to the environmental conditions encountered in a proofing chamber, said hollow housing exhibiting a continuous outer surface characterized by smooth, crevice free transitions intermediate non-parallel portions thereof and culminating in a pair of vertically extending horizontally spaced apart inner and outer end walls at opposite ends of said housing, an upper surface extending intermediate said inner end walls and including a plurality of longitudinally spaced apart dough receiving pockets and a lower surface extending intermediate said outer end walls and the sides of said upper surface and extending downwardly therefrom to enclose the undersides of said end walls, upper surface and pockets in cooperative mutually supportive relationship, and including an integrally molded receptacle having a peripheral cylindrical wall connected to and disposed to extend intermediate opposed interiorly disposed sides of each of said pair of inner and outer end walls at a location above said upper surface, for rotably mounting said tray, thereby providing a lightweight hollow structure that is self supporting and is further characterized by providing a crevice-free, continuous outer wall and a sealed, contaminant free interior.
Claim 2
Dependent Claim
208 words
A lightweight, longitudinally elongated, hollow proofer tray comprising in combination; a longitudinally elongated hollow housing having top bottom and end walls formed of a continuous layer of material impervious to the environmental conditions encountered in a proofing chamber, said hollow housing exhibiting a continuous outer surface characterized by smooth, crevice free transitions intermediate non-parallel portions thereof and culminating in a pair of vertically extending horizontally spaced apart inner and outer end walls at opposite ends of said housing, an upper surface extending intermediate said inner end walls and including a plurality of longitudinally spaced apart dough receiving pockets and a lower surface extending intermediate said outer end walls and the sides of said upper surface and extending downwardly therefrom to enclose the undersides of said end walls, upper surface and pockets in cooperative mutually supportive relationship, and including an integrally molded receptacle having a peripheral cylindrical wall connected to and disposed to extend intermediate opposed interiorly disposed sides of each of said pair of inner and outer end walls at a location above said upper surface, for rotably mounting said tray, thereby providing a lightweight hollow structure that is self supporting and is further characterized by providing a crevice-free, continuous outer wall and a sealed, contaminant free interior.
Claim 3
Dependent Claim
31 words
A proofer tray as set forth in claim 1 and including a plurality of upwardly and laterally extending rib portions intermediate the sides of the pockets disposed in the upper surface.
Claim 4
Dependent Claim
19 words
The subject matter of claim 1 in which the receptacles extend outwardly of each of the outer end walls.
Claim 5
Dependent Claim
17 words
The subject matter of claim 1 in which the receptacles are hollow for removably receiving an axle.
Claim 6
Dependent Claim
18 words
The proofer of claim 1 in which the lower surface of the housing includes a tensioned support means.
Claim 7
Dependent Claim
16 words
The proofer of claim 1 in which the high density plastic material includes a release agent.
Claim 8
Dependent Claim
16 words
The proofer of claim 1 in which the high density plastic material is resistant to wetting.
Claim 9
Dependent Claim
21 words
The proofer container of claim 1 in which the housing is hollow and is fabricated by the rotomolding process of manufacture.
