Abstract: The present invention is directed to a composition of matter to be applied to a carved pumpkin, more commonly called a jack o'lantern, in order to retard environmental degradation thereof, and to repel insects. The composition consists of an aqueous solution containing an antiseptic, a fungicide, an insecticide and a desiccant. The carved pumpkin is totally immersed in the aqueous solution to create a hyperosmotic condition to allow the preservative solution to permeate the fibers of the carved pumpkin, and at the same time replacing moisture from within the carved pumpkin with a mineral, to retain the original shape and structural stability of the carved pumpkin. The composition may also contain a buffer to maintain a pH level above 8.0. The present invention also provides a method of protecting a carved pumpkin using a composition according to the present invention.

Abstract: A canned beverage opener that is both functional and enjoyable to use. A rotating carousel containing several unopened beverage cans and ice is mounted to a base, with an inclined top. A drinking vessel is placed inside the base. When a consumer pulls on a handle, the canned beverage is opened by depressing the can's pop top, and the contents of the can are emptied into the vessel, thus simulating the tapping of a keg. Vent holes may be created in the cans by depressing a sharp tipped plunger mounted to the cover of the carousel. To open additional cans, the entire carousel may be rotated about a central shaft. Once all of the cans are empty, the consumer may remove the cover and replace the empty cans with unopened cans, and refill the ice if necessary.
