Abstract:

The present invention is directed at a lid for a cup. The lid comprising a disc having a periphery, a first face and a second face. The disc is corrugated to form a series of concentric, receiving channels having an opening and walls. The receiving channels are spaced apart so that both the first face and the second face can receive a cup wall of varying cup diameter. Additionally, the receiving channels have perforations to facilitate the removal of unused portions of the lid which extend radially outward from the cup wall. The lid has a tab which extends radially inward from the periphery of the disc and is formed by tab perforations on the disc. The tab hinges to the disc at a medial portion of the disc, and the tab can be opened by pivoting around the hinge and laying against the disc. Furthermore, the tab provides a starting point to tear along the perforations.

Abstract:

The present invention is a book having (a) a front cover, a back cover and a spline, forming an outer portion of a book; (b) a plurality of pages affixed within the outer portion of the book and containing a plurality of words constituting a text; (c) at least one page being a three-dimensional hollow frame structure with its front being at least partially made of see-through material. The frame structure is divided into an upper section and a lower section, separated by a wall having at least one connecting orifice, and containing a trap mechanism at each of said at the connecting orifice, and including a lever functionally connected to the trap mechanism. There is also a plurality of bead-like structures contained within the upper section of said frame structure, having a sufficient shape and size to flow via gravity through the connecting orifice of the upper section to the lower section when a user actuates the lever with the book in a substantially upright position.
