What is disclosed is a resealable flip-top beverage can having a rotatable sealing top mounted above the can top of the beverage can, and the sealing top is rotated into a first position to open a hole in the top of the beverage can and through which the contents of the can are dispensed, and is rotated into a second position where the sealing top reseals the hole. Sealing means are provided on the top of the can top and on the underside of the sealing top that cooperate to prevent beverage from getting between the can top and the sealing top when the can is opened, preventing matter from entering the can when it is resealed, and holding carbonation in said can when it is resealed. |

DETAILED DESCRIPTION In FIG.
1 is shown a view of a can top 10 of a conventional flip-top beverage can 11.
Ridge 20 and the "CLOSED" (not shown but under ring 14) and "OPEN HERE" indicia are added to implement the present invention.
As is known, can top 10 is manufactured separately from the container portion 12 of the can and is attached to container portion 12 after a beverage is placed therein.
There is a scoring 13 (shown as a dotted line) partially through can top 10.
Scoring 13 is pushed down using ring 14 in a manner well known in the art to open a hole 15 (not shown) by breaking scoring 13 so that the contents of can 11 may be dispensed.
In the prior art ring 14 is fastened to the middle of conventional can top 10 with a rivet type protrusion 16 that is formed as part of can top 10.
When ring 14 is lifted in a manner known in the art, a tip portion thereof is forced down against the portion of can top 10 within scoring 13 to rupture can top 10 within the area enclosed by scoring 13 to create hole 15 and thereby open beverage can 11.
The beverage in container portion 12 may then be consumed.
To implement the present resealable top invention some changes are made to the conventional can top 10.
First, during manufacture of can top 10 there is a upward extending, curved, raised ridge 20 formed around scored area 13 (hole 15) in FIG.
1.
The function of ridge 20 in implementing the invention is described further in this detailed description.
Second, rivet type protrusion 16 is made a little longer to captivate not only ring 14, but also another member (a sealing top 17) that is used in implementing the invention.
Sealing top 17 is described further in this detailed description.
In addition, the indicia "CLOSED" (not shown) stamped under key 14 and "OPEN HERE" within scoring 13 are stamped into the upper surface of can top 10 to aid in determining if the can is unopened, or opened and resealed as is described further in this detailed description.
Other indicia may also be stamped into can top 10
