Each of sheet of material has at least 20 microns in thickness and with the inclusion of the thickness adhesive is much cheaper than using a single 60 micron sheet.

Description

S P E C I F I C A T I O N
MULTI-LAYERED CROWN COVER FOR BEVERAGE CANS
FIELD OF THE UTILITY MODEL This utility model relates generally to flip-top beverage cans but more particularly to protective crown covers for beverage can.
BACKGROUND OF THE UTILITY MODEL
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 beverage 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. This health and hygiene problem encountered by consumers when drinking direct from flip-top cans was solve, by the developed and published in the WIPO PCT publication as WO03,011704. In said invention, a flip-top beverage can sanitary cover is described (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 materials and combination thereof; (c) 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; (d) to provide a cover material and combination of materials that is easily flexible, malleable, tearable, adhesible and stackable ; (e) to provide a cover material that is printable; and (f) to provide a cover with a flared skirt to protect the shoulder of the can. This sanitary cover which is made of aluminum was found to be easily destroyed due to it s thin construction, thus, defeating now the purpose of protecting the top portion of the beverage can.
Accordingly, the primary object of this utility model is to provide a multi- layered crown cover that seals the head and neck of the beverage can.
Another object of this utility model is to provide a multi-layered crown cover for beverage cans making use of different materials and combination thereof;
Still an object of this utility model is to provide a multi-layered crown cover for beverage cans that uses at least two layers of aluminum sheets having an approsimate total thickness of 60 microns more or less.
Yet, object of this utility model is to provide a multi-layered crown cover for beverage cans having an additional layer of PET material on top of the aluminum crowh cover which is flexible an non-toxic.
Another object of this utility model is to provide a a multi-layered crown cover for beverage cans that uses two layers of aluminum and a covering layer of PET, all of which are adhered by adhesive means such as glue. Still an object of this utility mocel is to provide a multi-layered crown cover for beverage cans that uses a layer of aluminum and a laminated paper on top thereof. Another object of this utility model is to provide a multi-layered crown cover for beverage cans that is simple yet easy to manufacture at a very low cost. The acquisition of two or more layers to obtain a specific thickness is much cheaper than having a single material of the same thickness. Other objects and advantages of the present invention will be made apparent and be understood upon a reading of the detailed description when taken in conjunction with the accompanying drawings.
DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
Figure 1 is a perspective view of a beverage can with the multi-layered crown cover according to the present utility model;
Figure 2 is a sectional view taken along line 3-3 of Figure 1 showing a combination of aluminum layer and PET layer as the materials used for the crown cover; . ·
Figure 3 is an enlarged fragmentary sectional view of Figure 2; Figure 4 is an enlarged fragmentary sectional view of similar to Figure
3 wherein the crown layers comprises of two layers of aluminum;
Figure 5 is an enlarged fragmentary sectional view of similar to Figure 3 wherein the crown layers comprises of two layers of aluminum and a layer of PET;
Figue 6 is ah enlarged fragmentary sectional view of similar to Figure 3 wherein the crown layers comprises of layers of aluminum, paper and PET; Figure 7 is an enlarged fragmentary sectional view of similar to Figure 3 wherein the crown layers comprises a layer of aluminum and a layer of laminated paper.
DETAILED DESCRIPTION Referring now to several views of the drawing wherein like reference numerals designate same parts throughout, there is shown a utility model for a multi-layered crown cover for berverage cans generally designated as reference numeral 10 and protects the top portion of a beverage can 12 from contaminants. The beverage can 12 is defined by a can body 13, a shoulder portion
14 disposed at the upper portion of said can body 13, and top end 15 being defined by an peripheral lip 16 crimped at upper portion of the shoulder 14, and a depressed planar panel 17 provided within said peripheral lip 16 on to where the scored pull tab 18 (in dotted lines) is disposed. Said crown cover 10 which is adapted to cover said top end 15 of said can body 13 is defined by a crown body 19 having a planar surface 20 disposed above said depressed planar panel 17 protecting the peripheral lip 16 and the entire depressed planar panel 17 of said top end 15, the periphery of said planar surface 20 projects downwardly with its outer lower portion 22 crimped at the base of said peripheral lip 16 of said can body 13 and a corrugated flaring skirt 23 extending diagonally and downwardly from said planar surface 20 to said shoulder portion 14 of said can body 19 to protect said shoulder from contaminants. Said crown cover 10 further comprises at least two layers of sheet material, a layer of aluminum 24 and a layer of PET 25 of approximately 20 microns each. Said sheets are adhered together and are likewise firmly adhered on the top end 15 of said can body 13 by thin layer of adhesives. It should be known that using two aluminum sheets of 20 microns each, more or less in thickness is much cheaper than using one 60 micron aluminum sheet or of equivalent thickness. The layer of adhesive constitutes the hardening of the two aluminum sheets. The thickness of the layer of adhesive covers and represents the remaining 20 microns of thickness. Different combinations of materials can also be used such as two layers of aluminum sheets 26 and 27 as shown in Figure 4, or another layer of PET 28 is added on top of the two layers of aluminum sheets 26 and 27 as shown in Figure 5. Figure 6 shows another combination, that is, layers of aluminum sheet 29, paper sheet 30 and sheet of PET 31 , and Figure 7 shows a combination of layers of aluminum sheet 32 and a sheet of paper 33 that are properly laminated to prevent said paper from being destroyed by moisture coming from water, oil, and the like.
