Abstract: A dual ovenable paperboard based structure which contains a food contact resin layer. The resin layer in direct contact with the ovenable food product exhibits superior food release properties, grease and oil resistance, and resistance to warpage even after extended periods of time following oven heating. The unique laminate is formed via coextrusion coating techniques on conventional coextrusion equipment at conventional temperatures. The resulting product has a high degree of adhesion between the paperboard and the polymethylpentene food contact layer, and is capable of being utilized for forming pressed or locked corner food trays which can be subjected to oven cooking temperatures.

Abstract: A wood chip sampling apparatus which includes a chip collecting tray. The tray moves to a first location where it collects a sample of downwardly flowing wood chips and then to a second location where it discharges the chips into a chip sample bin for later analysis. The tray is pivoted about a horizontal axis and is weighted on one side of the pivot axis so that it automatically assumes a horizontal, chip receiving orientation after chip discharge. An abutment prevents the tray from pivotting and dumping collected chips in the first tray location, the tray automatically pivotting to dump the chips when in the second location. The collecting tray thus reciprocates along a horizontal path and pivots over a range of 90 degrees.

Abstract: A paperboard carton in the form of a rectangular parallelpiped and formed by gluing and folding a scored, one-piece paperboard blank. The top panel or wall of the carton carries a series of perforated/cut lines which define a finger insertable carrying handle upon pushing inwardly by the user. A pair of thumb holes is provided on the top carton panel with each hole equidistantly spaced from the handle recess in the top panel. The carton may be carried by inserting a thumb in one of the thumb holes and the remaining fingers in the handle, thereby defining two lifting and carrying areas for the convenience of the user. The carton is particularly useful as a container for cans. In a modification, strain-relieving cuts are provided in the side walls, these cuts intersecting curved portions of finger perforated lines in the top panel.

Abstract: A rotatable wood chip thickness classifying device. The apparatus includes two coaxial, spaced sets of apertured discs, each set defining a drum. The interdisc spacing of each drum is uniform, each drum having a different interdisc spacing from the other drum. For each set of discs, the inside diameter of adjacent discs alternates. Wood chips are fed into the interior of the first drum, this drum having a typical disc interspacing of 2 mm. The common axis of drum rotation is slightly tilted to the horizontal and chips of less than 2 mm fall through the interdisc openings of the first drum. The remainder of the chips pass to the interior of the second drum, typically of 8 mm interdisc spacing. Chips less than 8 mm fall through the interdisc openings of the second drum. The alternation of inside disc diameters, for each drum, yields a chip tumbling effect to thereby inhibit an elongated chip, of a diameter of less than 2 mm for example, from straddling the 2 mm openings and not falling therethrough.

Abstract: A paper product having high stiffness, wet strength, and opacity, and good folding endurance is produced by subjecting a paper web containing a starch additive to high temperature heat treatment.

Abstract: A frence fry scoop/container formed from a unitary blank of paperboard. One sidewall of the container has a projecting tongue which functions both as a scoop and as a resilient or snap top closure. The second sidewall is provided with two parallel rows of tear perforations, to enable its major portion to be torn away. When the filled scoop/container is laid flat on the first sidewall, the second sidewall is ripped away, thereby exposing the entire stack of contents (french fries) and thus enabling the purchaser to add any desired additional condiments to the french fries.

Abstract: A one piece substantially rectangular corrugated paperboard blank is folded into a comparatively shallow tray type container for packaging a plurality of relatively tall bottles of potable liquid in a compact relatively immovable non-wobbling cluster so that the packages may be stacked one upon the other. A top panel has portions scored and cut from each other to form reinforcing inner end parts and a vertical center panel which forms a bridge across the tray to keep the sides from spreading and it also forms a dunnage bulkhead between the halves of the bottles to cushion them from each other in a tight condition within reinforcing corners which embrace the bottles securely.

Abstract: A pour spout seal construction for a gable top, thermoplastic coated type paperboard carton for packaging liquids. To permit easy unfolding of the folded pour spout within the top of the sealed carton by the consumer, the prior art has used adhesives to reduce the strength of the seal between the spout interior surfaces which are in surface contact with portions of the roof panels. In this invention, the opening action is different. Upon initial opening of the carton and subsequent unfolding of the pour spout, adhesive coating layers on the pour spout (located in positions homologous to the prior art adhesive coating layers) separate from the thermoplastic coating on the pour spout, instead of adhesive layers separating from themselves. Alternatively, the adhesive coating layers on the gable roof panels separate from the thermoplastic coating on the gable roof panels. In either case, the action is such that the adhesive coating layers stick to themselves upon pour spout unfolding.

Abstract: A disc screen wood chip sorter of the type having a series of corotating shafts, each of which is provided with an axially spaced series of concentric discs. The peripheries of the discs carried by one shaft interdigitate with those of the next adjacent shafts. The discs on any one shaft are maintained in parallelism by spacer elements in the general form of short cylindrical washers. The specific improvement of this invention relates to a novel configuration of these spacing elements. Each spacer end is provided with a flange to thereby define a central, annular groove or recess between the flanges, each annular receiving recess receiving a portion of the periphery of an adjacent disc, i.e., a disc mounted on a neighboring shaft. By virtue of this novel form of disc spacer, the disc screen sorter severely inhibits the passage of wood chips of a thickness greater than intended, i.e., chips of a thickness greater than the spacing between interdigitated discs.

Abstract: A paperboard container assembly for the microwave cooking and browning of food. The assembly is defined by an outer carton which surrounds a separate elongated tray. The tray is formed of a unitary blank of paperboard, a microwave interactive material and a polymer coating. The interactive material browns and crisps the food surface where contacted. The ends of the tray carry elongated, hollow feet to both support the tray bottom in vertially spaced relation to the carton bottom and to prevent shifting of the tray relative to the carton. Openings along the tray sidewalls and hollow feet prevent both scorching or burning of the paperboard and delamination of the polymer coating due to localized heat build-up.
