DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a front perspective view of a prior art soda can 10. The can 10 includes top portion 12, body portion 14, and bottom portion 16. The top portion 12 includes sections 12a, 12b, and 12c. A tab or pull tab 18 is shown attached to the top portion 12. The tab has been used to open the can 10 so that there is an opening 20 in the can 10.

FIG. 2 shows a front perspective view of the can 10 of FIG. 1 along with a cap 100 in accordance with an embodiment of the present invention. The cap 100 is shown in dashed lines. The cap 100 includes a flange or outer rim 102 and a central depression or portion 106. There is a gap 104 in the outer rim 102 so that a portion 18a of the tab 18 can fit over the central depression portion 106. The central depression or portion 106 fits over and into the opening 20.

FIGS. 3A, 3B, 3C, 3D, 3E, and 3F show top, front perspective, front, side, rear, and bottom views, respectively of the cap 100. FIG. 3B shows an inner wall 105 having an inner surface 105a and an outer surface 105b. FIG. 3F shows the bottom surface 108 of the depression 106. The cap 100 may resemble a hat in shape with the exception of gap 104.

In operation the indented portion 106 of the cap 100 can be inserted into the opening 20 of the can 10. The outer flange 102 of the cap 100 covers at least a portion of the to portion 12 of the can 10. The cap 100 provides a seal to keep any contents of the can 10 fresh after the tab 18 has been pulled to form the opening 20 in the can 10.

FIG. 4 shows a front perspective view of a can 200 along with a cap 300 in accordance with another embodiment of the present invention. Cap 300 is shown in dashed lines in FIG. 4. The can 200 may be the same as the can 10 with the exception that the can 200 may not have a tab, like tab 18. Can 200 includes top portion 212, body portion 214, and bottom 216. Can 200 may substantially be a hollow cylinder.

FIGS. 5A, 5B, 5C, 5D, 5E, and 5F show top, front perspective, front, side, rear, and bottom views, respectively of the cap 300. The cap 300 has a flange or outer portion 302 and a depression 304. The cap 300 includes an inner wall 305 having an inner surface 305a and an outer surface 305b. The cap 300 has a bottom surface 308, shown in FIG. 5F. The cap 300 does not have a gap, like gap 104, in the flange or outer portion 302.

In operation the indented portion 304 of the cap 300 can be inserted into an opening 220 of the can 200. The outer flange 302 of the cap 300 covers at least a portion of the portion 212 of the can 200. The cap 300 provides a seal to keep any contents of the can 200 fresh by sealing the opening 220 in the can 200.

Although the invention has been described by reference to particular illustrative embodiments thereof, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. It is therefore intended to include within this patent all such changes and modifications as may reasonably and properly be included within the scope of the present invention's contribution to the art.

Claims

1. A can sealing apparatus comprising: a cap base having an upper surface and an outer perimeter, said outer perimeter of said cap base dimensioned to facilitate insertion of said cap base into a flip-top can lid opening anda cap top defined by a peripheral flange extending outwardly relative to said outer perimeter of said cap base, proximate a first end of said cap base, said peripheral flange defining a generally flat C-shaped member having a first end and a second end, and by a flip-top can tab framing member positioned proximate said first end of said cap base and proximate said outer perimeter of said cap base, said flip-top can tab framing member defined in a non-flange region between said first end and said second end of said C-shaped member, thereby facilitating placement of flip-top can tab framing member of said can sealing apparatus in a position proximate to the exterior edges of an opened flip-top can tab that is extended vertically relative to a flip-top can lid surface when said cap base is inserted into said flip-top can top lid opening.
