20090114659 | Pressed Paperboard Servingware With Arched Bottom Panel and Sharp Brim Transition - A disposable servingware container | 05-07-2009 |
20090215599 | DISPOSABLE SERVINGWARE CONTAINERS WITH FLANGE TABS - Disposable containers include peripheral tabs which are useful for positioning and processing the containers and operate as separators. In a preferred embodiment, the tabs correspond to tabs on a paperboard blank where the tabs are useful for controlling the orientation of the blanks so that printed and shape features may be kept in registration during manufacturing of a disposable servingware container. | 08-27-2009 |
20090232926 | SEGMENTED PRESSWARE DIE SET WITH ANTI-TWIST GUIDE KEYS - A heated, segmented pressware die set for making pressware containers from a paperboard blank includes a plurality of guide keys mounted between at least one of an inner member of a punch or die and an outer ring which reciprocates independently. Each guide key extends in an outward direction from the central axis of the die set. The guide keys are positioned, configured and dimensioned to engage the outer ring in order to limit rotation of the outer ring with respect to the inner member of the punch or die. In a preferred construction, the guide keys have radially extending planar surfaces which cooperate with guide channels having like surfaces such that clearances necessary to accommodate thermal expansion are reduced, greatly increasing durability of the tool. | 09-17-2009 |
20100147938 | METHOD FOR IN-DIE LAMINATION OF PLURAL LAYERS OF MATERIAL AND PAPER-CONTAINING PRODUCT MADE THEREBY - A method for making a multilayered paper-containing product, for example a paper plate or tray, includes assembling two or more sheets of paper-containing material cut into blanks. The blanks are pressed together and shaped in a die, usually with a bonding agent being used to secure the blanks. Pleats are formed in the curved portion of the shaped product. However, the pleats on each blank are formed independently so that the folded region formed in the pleats are arranged in a staggered array and are not interleaved with the pleats of the other blank. | 06-17-2010 |
20100264202 | RIGID-BUCKLING-RESISTANT-FLUTED PAPERBOARD CONTAINER WITH ARCUATE OUTER REGION - The present invention relates to rigid-buckling-resistant-fluted containers with an arcuate outer rim. The container such as a pressformed paperboard plate of overall diameter “D” including a generally planar bottom region, an upwardly extending fluted region surrounding the generally planar bottom region, and an outwardly and downwardly extending peripheral region having an arcuate radial profile. The containers being produced of a lightweight board but exhibiting high strength and rigidity relative to the low weight board. | 10-21-2010 |
20110076127 | PRESSWARE STACKING SYSTEM AND METHOD FOR USING SAME - A pressware stacking assembly and method for using the same are provided. The stacking assembly may include a stacking surface for supporting a plurality of pressware products and at least one shaped wheel at least partially disposed through the stacking surface. The shaped wheel may include a body having at least three sides disposed about a perimeter thereof and at least one transition section disposed between adjoining sides, wherein each transition section is adapted to lift at least a portion of the pressware products off the stacking surface. | 03-31-2011 |
20110150620 | PRESSWARE STOP RAMP AND METHOD FOR USING THE SAME - Pressware stacking systems and methods for using same. The system can include a conveyor for moving pressware in a first direction; a stop ramp at least partially disposed on the conveyor; and a lifter in communication with the stop ramp. The lifter is adapted to move at least a portion of the stop ramp to an inclined position above the conveyor. | 06-23-2011 |
20120180546 | Blank Containment Device and Methods - Embodiments of the invention provide improvements to dies used in the formation of pressware from blanks In some embodiments, the die includes at least one stop that helps contain the blank as it is fed to the die and that allows for improved adjustability of the stop with respect to the die. In some embodiments, the die includes a defined recess that contains and centers the blank on the die as the blank is fed to the die. | 07-19-2012 |
20130309346 | PRESSWARE FORMING APPARATUS, COMPONENTS THEREFORE AND METHODS OF MAKING PRESSWARE THEREFROM - The present invention provides an improved pressware forming apparatus. At least one of die pairs used in the apparatus can be narrowed in a cross-direction as compared to the cross-directional width of pressware forming tools used in prior an apparatus. The present invention allows addition of at least one additional die pair in the pressware forming tool when used in a standard sized pressware forming apparatus. The present invention also provides components for use in such apparatus and methods of making pressware from the apparatus herein. | 11-21-2013 |
20140076905 | Pressed Paperboard Servingware with Improved Rigidity and Rim Stiffness - Products and methods of increasing the Rigidity and Rim Stiffness of disposable containers are provided. The containers have an outer flange portion extending outwardly with a brim portion sloping downwardly defining a declivity angle α with respect to a horizontal generally parallel to the bottom portion and generally include an outward turn at the periphery of the container. A preferred method of improving rigidity includes press-forming: (i) a brim transition portion adjoining the downwardly sloping brim portion of the container and (ii) an outwardly extending annular evert portion adjoining the brim transition portion extending outwardly at an eversion angle β of at least about 25 degrees with respect to the downwardly sloping brim portion of the flange. | 03-20-2014 |
