Abstract: A plastic food service article bearing a decorative mark or image and method therefor is disclosed. The method includes providing an article made from a colored plastic such as polystyrene, polypropylene, polyethylene, PET, PLA, ABS, etc., that discolors when irradiated with a laser beam; applying a laser beam to cause localized surface discoloration; and controlling the deflection and amplitude of the beam to form a surface decoration and/or image. In embodiments, the laser is a YAG or Fiber laser, the markings emulate silver or gold or pewter without applying metals, inks, or coatings to the plastic articles. The markings are clearly visible against both light and dark backgrounds, and can be placed in food-contact areas of the articles. The technique can be used for marking customized and personalized designs, images, and photographs on food service articles. Embodiments can be used to decorate plates and/or cutlery.

Abstract: A one-piece disposable cup lid enables drinking while inhibiting splashing and spilling by blocking straight-line paths through the lid and dispensing beverage through a well. A drinking spout can include a well having a sidewall, a bottom and a penetration into the cup, or a sloping lid section can intersect a raised rim to create a well therebetween, with a penetration in the sloping section or the rim configured to block straight-line paths, for example by upwardly hinging of a flap or depressing half of a split, convex bubble. Embodiments include baffles that force a beverage to flow through a convoluted path and/or through chambers before being consumed. Baffles can be formed in place, or by hinged movement of flaps after forming. Textures and/or protruding structures can intercept, direct, and/or influence surface tension as beverage flows across surfaces. Vent hole sizes and locations can further limit flow and spilling.

Abstract: A plastic knife adapted for resting on a table surface with the blade disposed in a vertical orientation. The knife includes a blade connected to a handle, a top wall, a middle wall and a bottom wall. The middle wall is connected to the blade and is orthogonal to the top and bottom walls. The blade includes a narrow blade tip and a cutting edge. The top wall features a tapering profile with a wide handle end, a narrow blade end, and a transition area of intermediate widths. The transition area is disposed between the wide handle end and the narrow blade end. The bottom wall includes a flat section for resting on a flat table surface. The knife features superior functionality and strength and may include a thin metallic coating deposited on at least a portion of one of its surfaces.

Abstract: A hot beverage lid having thermal protective flex-guards or flaps extending from opposite sides of a cover portion of the lid for protecting a consumer's fingers from heat emanating from the side of a cup. A first flap extends a first distance from under a drinking opening having sufficient area for a thumb. A second flap extends a second distance which is greater than the first flap from the opposite side of the lid and has sufficient area for at least two fingers. Each flap is contoured to conform to the curvature or the sidewall of the cup and each flap comprises swirled rib embossing for improved retention against fingers holding the cup. The top of the cover portion is concave with a hole in the center to allow liquid spillage to reenter the cup. Also, a channel surrounding the base of a circular plateau on top of the cover of the lid is provided for collecting fluid spillage.
