Abstract

A protective cap for canned soft drinks and the like is disclosed. The cap comprises an outer periphery configured to receive and snap over the upper surface of a conventional soft drink beverage can. A lip guard extends axially downward from the cap to provide a sanitary drinking surface. A grate is positioned to cover the opening in the top of the can through which the beverage may be consumed. The grate is formed as an integral portion of the molded cap. A hinged cover can rotate between opened and closed positions to permit consumption of the soft drink when in the opened position and to seal the container to prevent contamination from airborne debris and small insects when in the closed position. A detent formed upon the lower surface of the cover is received between adjacent bars of the grate to latch the cover in the closed position.

Claims

1. A protective cap for preventing insects, airborne debris, and the like from entering beverage containers, the cap comprising:

(a) a generally planar surface;

(b) a peripheral portion formed substantially perpendicular to said planar surface at the periphery of said planar surface, said peripheral portion having a detent formed thereon for releasably attaching the protective cap to a beverage container;

(c) an opening formed in said planar surface;

(d) a grate formed within said opening; and

(e) a cover hingeably attached to said planar surface such that said cover can be rotated between an opened position and a closed position; and

(f) a detent pin formed upon the lower surface of said cover; and

(g) wherein said detent pin engages said grate when said cover is in the closed position, said detent pin and said grate cooperating to latch said cover in the closed position.

2. The protective cap as recited in claim 1 wherein said grate is sized and configured such that fluid flows substantially unrestricted therethrough and such that bees cannot pass therethrough.

3. The protective cap as recited in claim 2 further comprising a lip guard formed about a portion of the periphery of said planar surfaces.

4. The protective cap as recited in claim 3 wherein said grate is comprised of alternating bars and apertures, said bars being approximately 0.0625 inch wide and said apertures being approximately 0.06215 inch wide.

5. The protective cap as recited in claim 4 further comprising:

(a) a first lip formed upon said planar surface;

(b) a corresponding second lip formed up said cover; and

(c) wherein said first and second lips cooperate to seal said opening when said cover is disposed in the closed position.

6. The protective cap as recited in claim 5 further comprising a plurality of connecting links for attaching a plurality of protective caps together, each connecting link attaching the protective caps together such that the protective caps may be separated by manual force.

7. A protective cap and packaging device for beverage containers, said device comprising:

(a) a plurality of generally planar surfaces;

(b) a peripheral portion formed substantially perpendicular to each of said planar surfaces at the periphery of each of said planar surfaces, each of said peripheral portions having a detent formed thereon for releasably attaching the protective cap to a beverage container;

(c) an opening formed in said planar surface;

(d) a grate formed within said opening;

(e) a cover hingeably attached to said planar surface such that said cover can be rotated between an opened position and a closed position; and

(f) a plurality of connecting links formed intermediate said planar surfaces for attaching said planar surfaces together such that said planar surfaces may be separated by manual force.

8. The protective cap and packaging device, as recited in claim 7, further comprising:

(a) a detent pin formed upon the lower surface of said covers; and

(b) wherein said detent pins engage said grates when said covers are in the closed position, said detent pins and said grates cooperating to latch said covers in the closed position.

9. A protective cap and packaging device for beverage containers, said device comprising:

(a) a plurality of generally planar surfaces;

(b) a peripheral portion formed substantially perpendicular to each of said planar surfaces at the periphery of each of said planar surfaces, each of said peripheral portions having a detent formed thereon for releasably attaching the protective cap to a beverage container, said peripheral portions cooperating with said generally planar surfaces to form recesses sized and configured to receive the bottoms of beverage containers such that stacking is facilitated;

(c) an opening formed in said planar surfaces;

(d) a grate formed within said openings; and

(e) a plurality of connecting links formed intermediate said planar surfaces for attaching said planar surfaces together such that said planar surfaces may be separated by manual force.
