Abstract: A method of making a cup that decreases the amount of flash on a bottom surface of the cup is provided. More specifically, a cup is provided that includes a thickened lip around an open surface. The lip also includes a recess for the receipt of excess material generated by the molding process. This excess material, or flashing, is detrimental to the use of cups in cup stacking competitions.

Abstract: The present invention discloses an improved holding device which allows for retaining, storing and transporting cups used in sport stacking. The invention allows a user to quickly and conveniently store and transport a stack of sport stacking cups using only one hand, by employing a unitary stem incorporating retractable tangs that retain the stack of cups. The tangs may be withdrawn via a spring-loaded plunger, activated by the user's thumb. The invention also includes the use of a shield mechanism, as well as various cup transporting mechanisms.

Abstract: The present invention describes an apparatus and method for timing manual dexterity and hand-eye coordination competitions. Specifically, the present invention relates to an apparatus and method for timing cup stacking competitions. The apparatus of the present invention includes a mat which may incorporate a timer and the cups which are to be stacked on the mat. One embodiment of the present invention includes a multi-pieced timing mechanism which may be selectively interconnected to a mat. Further, a plurality of these timing mechanisms may be used remotely from the mat or with the mat such that a plurality of players may be used in individual mats.

Abstract: A series of interconnected packing chip precursors that can be formed and transported economically to a packager as a flat sheet and then expanded at the site where they will be used into individual packing chips by folding and separation from the other chips. Preferably, the precursors are formed on a chipboard sheet by forming fold lines and lines of separation and by adding securing means, such as bonding media or connecting features to secure the sides of the expanded packing chip in its final shape. The fold lines and lines of separation can be configured to form jagged or serrated edges on the expand-on-site packing chip, and the chip may also include apertures; the jagged and serrated edges and the apertures cooperating with each other and other aspects of adjacent chips to interlock the chips when they are placed around an item in a package for shipment.
