Flip-Top Beverage Can Sanitary Cover APPLICANT
4 Dante R Olivar CROSS REFERENCE TO RELATED APPLICATIONS
I claim the benefit of Philippines patent application number 000-1022.
Filed : 24 April 2000 9 1. Field of the Invention This invention relates generally to flip-top beverage cans.
11 2. Prior Art 12 Flip-top beverage cans are typically stored or displayed for sale without any 13 packaging. Overtime contaminants accumulate on their topslends and especially 14 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 16 directly drinks from the can. Even when the beverages are poured into a glass, 17 the contaminants on the rim would still be washed into the glass.

2 Accordingly, the objects and advantages of the present sanitary and protective 3 cover are:

4 ( 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 6 rials and combination thereof;
7 (c) to be easy and inexpensive to make and apply;
8 (d) to provide a sanitary cover that eliminates the direct contact of the lips and 9 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, 11 malleable, teareable, adhesible and stackable;
12 (f) to provide a cover material that is printable;
13 (g) to provide a cover with a flared skirt to protect the shoulder of the can.
14 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
16 This present invention provides a solution to the health and hygiene problem 17 encountered by consumers when drinking direct from flip-top cans, by suggesting 18 an article and a method of covering the surface, neck and down to the portion of 19 the can that comes in direct contact with the lips of the consumers.

13 A first embodiment of the present sanitary cover is shown in a perspective view 14 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 13, 16 a concave rim 14 around the perimeter of a disc 13 and a flared skirt 15 extend 17 ing from concave rim 14. Rim 14 is convex when viewed from the inside of 18 cover 10.
19 Cover 10 may be made out of a plastic material, such as polyethylene, polypropy lane, nylon, paper, aluminum, and other present and future materials and combi 21 nations, etc. Cover 10 is applied on top of the can by virtue of combination tech 1 nologies in molding, extrusion, capping, wrapping, punching, sealing and adhe 2 sion. In Fig. 2 & 2A, cover 10 is applied to the can 12.
3 In Fig. 3 concave rim 14 of cover 10 is snugly engaged around a convex lip 16 of 4 can 12 to retain cover 10 in position. Flared skirt 15 is shaped to conform closely 5 to a tapered shoulder 17 of can 12 and is long enough to extend at least down to 6 a transition 18 between tapered shoulder 17 and a vertical wall 19 of can 12.

7 Advertising may be printed on cover 10.

8 Accordingly, top 11 and shoulder 17 of can 12 are protected by cover 10 from 9 contaminants. Cover 10 can be easily peeled off from can 12.
Fig. 4 & 4A:
11 As shown in Fig. 4, the cover 10 may also be made by molding a flat sheet 12 and heat shrink applied onto top 11 of can 12. Alternately, sheet 20 may be glued.
13 Fig. 5 & 5A:
14 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 16 press 22 is shaped to conform to top 11 of can 12. Flat sheet 21 may be made of 17 any deformable material, such as paper, aluminum, plastic, etc. Flat sheet 18 may be retained on can 12 by friction, adhesion, meachanically tightening, etc.
19 Fig. 6 & 6A
As shown in Fig. 6, cover 10 is detached from can 12 by inserting anger under 1 spaces provided in between the flared skirt 15 of cover 10. In Fig. 6A, cover 10 is 2 shown as completely detached and separated from top 11 of can 12 3 Figs. 7 to 7F:
4 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.
