A method for manufacturing a sanitary cover for a beverage can and relates to a technique for forming a cutting line along a circumferential surface of a sanitary cover while the sanitary cover is covering a beverage can, thereby maximizing the production efficiency of the sanitary cover having improved functionality. Also, the technique which, in three-dimensionally forming a cutting line as such, can carry out the process of forming the cutting line easily and rapidly via a simple structure, thereby increasing the production efficiency even further.

A cover for a beverage can includes a circular disc, an opening within the circular disc, and a raised lip fixedly attached to a circumference of the circular disc. The cover for a beverage can is useful for providing a means for covering a beverage can when in an opened condition, so as to prevent insects and debris from entering the beverage, to prevent release of carbonated gas from the beverage and to prevent premature warming of the beverage.

A cover for sealing a container having an interior chamber that holds a quantity of material therein. A first channel provided on a base of the cover receives a rim on the container's side wall. A first sealing member is provided on the base. A second sealing member provided on the lid is complementary to the first sealing member and is engageable therewith when the lid is moved to a closed position. A flexible bridge extends between the base and the lid. One of the first or second sealing members is a protrusion and the other is a second channel. The protrusion may be received within the second channel when the lid is closed. Pressure may be progressively applied to the lid to zipper the cover into a sealed position. When the lid is in the sealed position material cannot be accidentally or purposefully removed from the interior chamber.

The Disposable Soda Can Cover is manufactured of any suitable material including waxed or coated, food grade, sanitary paper, and is semicircular or a half moon in shape, comprising a semicircular top circumscribed by a ridge which is constructed to receive the top edge or rim of a beverage can and cover the opening of the can.

A container top comprising a container top member comprising tracks over an upper surface thereof and a sealer sealing an opening thereof; and a slidable member having a sealing mechanism, the slidable member being slidable through the tracks and positioned such that sliding of the slidable member over the tracks to one direction unseals the sealer, forming an opening over the container top member, in the initial opening thereof and wherein sliding the slidable member back to its original position over the opening formed thereby covers and seals the opening. The opening formed by the unsealing of the sealer can be re-sealed at will by the sealing mechanism of the slidable member. The sealing mechanism may be for example a sealing material coating strip located over a periphery of the slidable member or the physical configuration of the slidable member periphery edges.

A can cover having an inner cover comprising a circular groove in which an upper sealing portion of said can is inserted. An inner O-ring is tightly attached to said upper sealing portion of said can. Said inner O-ring is inserted into said circular groove of said inner cover. Also included is an outer coupling ring having a plurality of coupling protrusions inserted into a plurality of coupling grooves formed in an outer circumferential portion of said inner cover. A clearance is formed between said coupling grooves such that when said outer coupling ring is separated from said inner cover, said clearance spreads and separates said inner cover from said upper sealing portion of said can.

Provided herein is a re-usable device that would allow for the export of, or consumption of liquid without having to remove the device from the can such as the aluminum beverage can and that would also seal the liquid inside a beverage can. A water-resistant or water-proof, insect-proof, dirt-proof synthetic cap is provided that is to be attached to the lip area of the open mouth of can or other open mouth container, such as metal, plastic or an aluminum beverage can.
