Abstract: The present invention is generally directed to a container having first and second hollow chambers attached to a top. The first chamber has a helical surface that can be placed adjacent to a corresponding helical surface of the second chamber. The top can include a pair of apertures for receiving a straw such that one aperture resides above each chamber. A straw can be placed into one of the apertures when one desires to drink from the container. The drinking container can further include an attachment device for better attaching the helical chambers.

Abstract: A biological specimen cassette adapted to be installed with similarly constructed cassettes as a package in a cassette dispenser from which cassettes are thereafter dispensed individually comprises a channel formed in at least one of its walls to receive a connecting element, such as band, string or wire, which, when engaged to all cassettes, form a collective stacked arrangement of cassettes which is insertable into the cassette dispenser. Once received in the dispenser, the connecting element is then retrieved so that individual cassettes may be individually dispensed.

Abstract: By providing a prize awarding system which is secretly incorporated into a multi-packed product or assembly, a unique prize delivery system is realized. In the preferred embodiment of the present invention, the prize award system incorporates a separate, independent housing constructed for being inserted into the void zone or open area which exists between the adjacent product holding containers forming a multi-pack assembly. Although the present invention is employable with any multi-pack product or assembly, products retained in cans, bottles, or similar vessels typically benefit most extensively from the present invention. In the present invention, the prize awarding system incorporates the actual prize or incorporates means for informing lucky consumers that a prize has been won, either in an audible or visual message delivery system, on certificates, vouchers, or similar printed materials, or in an electronic chip assembly.
