Abstract: The bottom portion of a cupshaped vessel adapted to fit snugly over the rim of a conventional beverage can is provided with a selectively slotted opening preferably bounded by a sealing rib, the opening being contoured to approximate the usual pull-tab opening in the beverage can to provide a drinking attachment therefor. A second sealing rib may be provided to reseal the opening of the beverage can for storage and transport upon the rotation of the drinking attachment from a first or drinking position to a second or sealing position. The vessel may be provided with a lid portion to serve as a product container the contents of which may be emptied and the vessel thereafter used as a drinking attachment.

Abstract: A bicycle construction for tandem operation includes an auxiliary drive means which may be attached to a conventional single operator bicycle between the main drive means and the rear wheel to permit operation by two occupants. The auxiliary drive means comprises a pair of first auxiliary sprockets each connected to an associated one of a pair of independently supported rotary pedals each of which is coupled to an associated fork of a forked rear wheel support. A pair of second auxiliary sprockets is mounted on the main drive means, each of the second auxiliary sprockets being coupled to a respective one of the main rotary pedals. A pair of support columns coupled to the bicycle frame may be provided to serve as an auxiliary seat support, at one end, and as an auxiliary rotary pedal support at its other end. The auxiliary crank arms associated with the auxiliary rotary pedals may be coupled to eccentrically mounted bearing for adjusting the spacing between the auxiliary drive means and the main drive means.
