TITLE OF THE INVENTION

Flip-Top Beverage Can Sanitary Cover

APPLICANT

Dante R Olivar

CROSS REFERENCE TO RELATED APPLICATIONS

I claim the benefit of Philippines patent application number 000-1022.

Filed : 24 April 2000

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to flip-top beverage cans.

2. Prior Art

Flip-top beverage cans are typically stored or displayed for sale without any

packaging. Overtime contaminants accumulate on their tops/ends and especially

around the end's crevice. These contaminants mix with the overflow of the bever

age from the can and is washed into the digestive system of a consumer who

directly drinks from the can. Even when the beverages are poured into a glass,

the contaminants on the rim would still be washed into the glass. OBJECTS AND ADVANTAGES OF THE INVENTION

Accordingly, the objects and advantages of the present sanitary and protective

cover are: ( a) to provide a sanitary cover that seals the head and neck of the can; (b) to provide a protective cover for aluminum cans making use of different mate

rials and combination thereof;

(c) to be easy and inexpensive to make and apply; (d) to provide a sanitary cover that eliminates the direct contact of the lips and

mouth of consumers to the unhealthy particles that reside on top of the can; (e) to provide a cover material and combination of materials that is easily flexible,

malleable, teareable, adhesible and stackable; (f) to provide a cover material that is printable; (g) to provide a cover with a flared skirt to protect the shoulder of the can.

Further objects and advantages of the present invention will become apparent

from a consideration of the drawings and ensuing description.

BRIEF SUMMARY OF THE INVENTION This present invention provides a solution to the health and hygiene problem encountered by consumers when drinking direct from flip-top cans, by suggesting

an article and a method of covering the surface, neck and down to the portion of the can that comes in direct contact with the lips of the consumers. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

DETAILED DESCRIPTION OF THE INVENTION

Figs. 1-3 & 1A-3A: A first embodiment of the present sanitary cover is shown in a perspective view

in Fig. 1 & 1A. It is comprised of a flexible cover 10 for the top 11 of a conventional beverage can 12. Cover 10 is comprised of a round disc 3, a concave rim 14 around the perimeter of a disc 13 and a flared skirt 15 extend

ing from concave rim 14. Rim 14 is convex when viewed from the inside of cover 10.

Cover 10 may be made out of a plastic material, such as polyethylene, polypropy

lene, nylon, paper, aluminum, and other present and future materials and combi nations, etc. Cover 10 is applied on top of the can by virtue of combination tech nologies in molding, extrusion, capping, wrapping, punching, sealing and adhe

sion. In Fig. 2 & 2A, cover 10 is applied to the can 12.

In Fig. 3 concave rim 14 of cover 10 is snugly engaged around a convex lip 16 of

can 12 to retain cover 10 in position. Flared skirt 15 is shaped to conform closely

to a tapered shoulder 17 of can 12 and is long enough to extend at least down to

a transition 18 between tapered shoulder 17 and a vertical wall 19 of can 12.

Advertising may be printed on cover 10.

Accordingly, top 11 and shoulder 17 of can 12 are protected by cover 10 from

contaminants. Cover 10 can be easily peeled off from can 12.

Fig. 4 & 4A:

As shown in Fig. 4, the cover 10 may also be made by molding a flat sheet 20

and heat shrink applied onto top 11 of can 12. Alternately, sheet 20 may be glued.

Fig. 5 & 5A:

As shown in Fig. 5, another method for making the crown is comprised of

pressing a flat sheet 21 onto top 11 of can 12 with a press 22. A cavity 23 in

press 22 is shaped to conform to top 11 of can 12. Flat sheet 21 may be made of

any deformable material, such as paper, aluminum, plastic, etc. Flat sheet 21

may be retained on can 12 by friction, adhesion, meachanically tightening, etc.

Fig. 6 & 6A :

As shown in Fig. 6, cover 10 is detached from can 12 by inserting finger under spaces provided in between the flared skirt 15 of cover 10. In Fig. 6A, cover 10 is

shown as completely detached and separated from top 11 of can 12

Figs. 7 to 7F:

Cover 10 is shown on top 11 of can 12 in two variations. Fig. 7 is made of

modified aluminum, while Fig. 7A is made of modified plastic. Fig. 7B shows a

variation of a flared skirt 15 of cover 10 on can 12. Fig. 7C shows another varia

tion of a flared skirt 15 on top 11 of can 12. Figs. 7E and 7F shows another

variation of a flared skirt 15 on top 11 of can 12.

Fig. 8:

A plurality of covers 24 are connected together with integral links 25 there be

tween , and are prefferably made by molding. The plurality of linked 25 covers 24

on top of multi-pack cans may be applied by heat-shrink wrapping, pressing.gluing

and mechanically tight-fitting.

Accordingly, the present sanitary cover 10 protects the top 11 of a flip-top

beverage can 12 from contaminants. The flared skirt 15 protects the shoulder 17

of the can 12 from contaminants. The cover 10 is easy to apply and detach from the can 12 and inexpensive to make. Cover 10 with flared skirt 15 also provides

space for print promotionals 26.

Although the above description is specific, it should not be considered as a limitation on the scope of the invention, but only as an example of the preffered

embodiment. Many variations are possible with the teachings of the invention.

For example, different attachment methods, fasteners, materials, dimensions, contortions, etc. can be used and applied unless specifically indicated otherwise. The relative positions of the elements can vary, and the shapes of the elements

can vary. Therefore, the scope of the invention should be determined by the appended claims and their legal equivalents, not by the examples given.
