Patent number: 8575296Abstract: A polyester article is made to appear lustrously metallic or pearlescent by the addition of polymethylpentene and non-metallic, non-pearlescent colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combination thereof. A stretch blow molded plastic article, such as a bottle, using the polymethylpentene in the polyester can simulate the appearance of a metallic surface or a pearlescent luster even though non-metallic and non-pearlescent colorants are used.Type: GrantFiled: September 29, 2009Date of Patent: November 5, 2013Assignee: PolyOne CorporationInventors: Gary Vernon, David Rosendale

Patent number: 7475804Abstract: A food container has a box base with four side panels and four bottom flaps extending from the respective side panels to close the floor of the box base leaving the top open. The bottom flaps are so designed and glued together that the box sides can be folded flat for stacking and then unfolded into a box structure having its bottom wall closed automatically. The box base provides food-receiving area while carrying and serving the eatery. Raised from the top of the box base are circumferential edges defining a tray top. The tray top carries out the decorative role when it is popped open as is possible thanks to the inventive folding scheme implemented in the tray top. The tray top also has carrying handles for the user. The front face of the tray top in the serving mode can be decorated with various cutouts shaped as interesting objects.Type: GrantFiled: May 28, 2005Date of Patent: January 13, 2009Assignee: Americhip Inc.Inventors: Timothy Clegg, David Rosendale

Patent number: 5843262Abstract: A novelty piece is fabricated from a single sheet of paper printed on both sides with indicia in registration. Scoring, perforating and cut lines are provided at predetermined positions and an adhesive is applied at preselected locations and the sheet is then folded and adhered in the folded position. a second fold into an adhered position followed by a trimming yields a completed piece ready for use. The completed piece can be selectively opened into one of two positions to display different indicia. The selective display of different indicia with either opened position can be utilized to create illusions or a multiple selection or fortune telling game.Type: GrantFiled: April 17, 1997Date of Patent: December 1, 1998Assignee: Intervisual Communications Inc.Inventors: David Rosendale, Rebecca Forsythe
