BACKGROUND
This disclosure relates generally to a beverage can lid having an opening, and more particularly to a resealable beverage can lid for covering the opening.
Beverage cans for containing liquids such as carbonated beverages have become a universal and ubiquitous product. The beverage can is typically constructed of an aluminum alloy composition that may include aluminum, magnesium, manganese, silicon, and copper. The beverage can consists of a can body into which a liquid is filled and a can lid or end that is sealed to the can body. The can body may include a base or bottom that is dome shaped to resist internal pressure, a generally cylindrical section, a narrowed neck portion, and an open top edge. The can lid may include the lid portion that is about the same circumference as the narrowed neck portion of the can body, a scored line or weakened portion cut into the lid portion to form a panel or a tear panel having a hinge, a tab portion that is used to rupture the lid portion along the scored line to create an opening, and a rivet that is used to secure the tab to the lid portion. The rivet is an integral piece of the lid portion and is formed by stretching the center of the lid portion upwardly and then drawn to form the rivet. The lid is sealed to the can body by trimming the open top edge of the can body, bending the trimmed edge, and seaming the bent trimmed edge to the lid. In this manner, any liquid contained within the can body is sealed. To open the beverage can the tab is lifted to press against the tear panel to partially push the tear panel into the can body to create the opening in the lid. The panel does not fully detach from the lid due to the hinge portion formed in the lid by ends of the score line. Once opened, liquid from inside the can body may flow through the opening.
One problem associated with the use of the beverage can is that once opened it cannot be closed again. Since the liquid within the beverage can may be carbonated, after a period of time the carbonation escapes and the liquid becomes flat or stale. Once flat, the beverage can and its contents may be discarded which may be wasteful. Also, after opening the beverage can the contents may have to be consumed quickly because the contents cannot be preserved. Further, it is also possible that the contents of the beverage can may spill due to not being able to close the opening. In particular, when an individual is walking with an opened beverage can the individual may trip or fall and the contents of the can may be spilled because the can is open. This may also be problematic if the beverage can is stationary and near electrical equipment such as a computer or a laptop and the can is accidentally knocked over. It is also possible that insects, contaminants, or other unwanted matter may infiltrate the beverage can through the opening. If this occurs, then the beverage can and its contents should be thrown away.
The present disclosure is designed to obviate and overcome many of the disadvantages and shortcomings experienced with prior beverage can constructions. Particularly, it would be advantageous to be able to have a resealable beverage can lid for preserving the contents of the beverage can. Moreover, the present disclosure is related to a resealable beverage can lid that can be easily resealed for later use, to prevent spillage, or to prevent contaminants from entering the can once opened.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings, wherein like numbers refer to like items, number 10 identifies a preferred embodiment of a resealable beverage can lid constructed according to the present disclosure. Referring now to FIG. 1, the resealable beverage can lid 10 is shown to comprise a lid 12 having a top side 14 having a score line 16 for forming a completely separable tear panel 18. The lid 12 has a first rivet 20 formed therein with the first rivet 20 extending outwardly from the top side 14 of the lid 12. A second rivet 22 is formed within the tear panel 18 and extends outwardly from the top side 14 of the lid 12. A tab element or portion 24 is connected to the first rivet 20 and the second rivet 22. The tab portion 24 is used to open the lid 12 by rupturing the score line 16 to completely free the tear panel 18 from the lid 12. The tab portion 24 comprises a main body portion 26 having a rear lifting portion or end 28 and a forward rupturing portion or end 30. A generally U-shaped opening 32 is used to form a generally semicircular portion or tongue 34 that has a first aperture or first rivet opening 36 formed therein for receiving the first rivet 20. In this manner, the tab portion 24 is staked or held to the lid 12. The first aperture 36 also allows the tab portion 24 to rotate or move about the first rivet 20. The tab portion 24 also has a front portion 38 having a second aperture or second rivet opening 40 formed therein for receiving the second rivet 22. In this manner, the tab portion 24 is staked or held to the tear panel 18. An opening 42 may also be formed in the rear lifting portion 28 of the tab portion 24. Although hidden from view in this drawing figure, the score line 16 completely surrounds the panel 18 which allows the panel 18 to be completely freed from the lid 12 when the score line 16 is ruptured. The score line 16 is ruptured by use of the tab portion 24. Once the tear panel 18 is fully separated or detached from the lid 12, the tab portion 24 may be moved to move the tear panel 18. As can be appreciated, the lid 12 is shown in a closed or unopened condition in that score line 16 has not been ruptured to completely detach the panel 18 from the lid 12.
FIG. 2 is a bottom view of the lid of the resealable beverage can lid 10. The lid 12 has a bottom side 44 having a first rivet indentation 46 and a second rivet indentation 48 in the bottom side 44. The indentations 46 and 48 are left over from the manufacturing process that forms the rivets 20 and 22 (FIG. 1). The score line 16 is shown in phantom in this particular view. The score line 16 completely surrounds the tear panel 18 with the tear panel 18 taking on the shape or outline of the score line 16. The bottom side 44 may also have formed therein a reinforcing rib 50 to help in strengthening the lid 12. Again, the lid 12 is shown in a closed or unopened position in that score line 16 has not been fractured or ruptured to separate the panel 18 from the lid 12.
With reference now to FIG. 3, a partial cross-sectional view of the resealable beverage can lid 10 being connected to a beverage can 70 is shown. The lid 12 has a flange 72 that is shaped to receive a neck portion 74 of a cylindrical can body 76. The can body 76 has an interior 78 in which a liquid 80, such as a carbonated beverage, is filled. As can be appreciated, the lid 12 is used to seal or cap the neck portion 74 of the can body 76. The lid 12 has the top side 14 having the score line 16 surrounding the panel 18. The lid 12 has the first rivet 20 that extends outwardly from the top side 14. The panel 18 also has formed therein the second rivet 22 that extends outwardly from the top side 14 of the lid 12. The lid 12 also has the bottom side 44 which has the first rivet indentation 46 and the second rivet indentation 48 formed therein. The tab portion 24 is staked to the lid 12 by the first rivet 20 and to the tear panel 18 by the second rivet 22. The rear lifting portion 28 and the forward rupturing portion 30 of the tab portion 24 are also illustrated. The panel 18 is shown in an initial closed position in which the score line 16 has not been ruptured. The liquid 80 within the beverage can 70 cannot escape because there is no opening in the lid 12.
FIG. 4 illustrates a top view of the resealable beverage can lid 10 connected to the beverage can 70 with the tear panel 18 being separated from the lid 12 along the score line 16 and in the process of being moved into an opened position. The tab portion 24 has been slightly rotated or moved so that the tear panel 18 is no longer covering an opening 82 formed by rupturing the score line 16. The liquid 80 within the beverage can 70 is now visible and able to be removed or emptied from the can 70. The tab portion 24 may be moved to seal, block, or close the opening 82. Once the panel 18 is moved into the closed position the liquid 80 within the beverage can 70 is prevented from escaping or being spilled. To reopen the opening 82, the tab portion 24 is grasped by the rear lifting portion 28 to move the panel 18 back into the interior 78 of the beverage can 70. Once the panel 18 is re-positioned into the opened position, any contents within the beverage can 70 may be removed, used, or emptied. The second rivet 22 is used to prevent the tear panel 18 from falling into the beverage can 70. The first rivet 20 is used to keep the tab portion 24 staked to the lid 12 so that the tab portion 24 may be moved to open or close the opening 82.
Referring to FIG. 5, an enlarged cross-sectional view of the resealable beverage can lid 10 with the tab portion 24 removed is depicted. The resealable beverage can lid 10 has the lid 12 having the top side 14 and the bottom side 44. The top side 14 has the score line 16 formed therein for outlining and forming the panel 18. The lid 12 has the first rivet 20 formed therein with the first rivet 20 extending outwardly from the top side 14 of the lid 12. The first rivet 20 has the first rivet indentation 46 formed in the bottom side 44 of the lid 12 during the manufacturing process that forms the first rivet 20. The second rivet 22 is also formed in the lid 12 and extends outwardly from the top side 14 of the lid 12. The second rivet 22 has the second rivet indentation 48 formed in the bottom side 44 of the lid 12. The second rivet indentation 48 is leftover after forming the second rivet 22.
FIG. 6 shows a top view of the tab portion 24 before the tab portion 24 is connected to the first rivet 20 and the second rivet 22. The tab portion 24 comprises the main body portion 26 having the rear lifting portion or end 28 and the forward rupturing portion or end 30. The generally U-shaped opening 32 is used to form a generally semicircular portion or tongue 34 that has the first aperture 36 formed therein for receiving the first rivet 20 (not shown). The first aperture 36 also allows the tab portion 24 to rotate or move about the first rivet 20. The tab portion 24 also has the front portion 38 having the second aperture 40 formed therein for receiving the second rivet 22 (not shown). The tab portion 24 may also have a reinforced edge 84 that adds strength to the tab portion 24 so that the tab portion 24 is strong enough to separate the panel 18 from the lid 12. The opening 42 is also shown being formed in the rear lifting portion 28 of the tab portion 24.
The operation of the resealable beverage can lid 10 may be as follows. The can body 70 is filled with the liquid 80 and the lid 12 is sealed to the can body 70 and the product is then made available for purchase to an individual or consumer. Once purchased and the individual wants to use the product the individual will lift the rear lifting portion 28 of the tab portion 42 which causes the forward rupturing portion 30 to press against the panel 18 to rupture the panel 18 along the score line 16. This causes the panel 18 to completely separate from the lid 12 and to move into the interior 78 of the can body 76 to create the opening 82. However, the panel 18 is prevented from falling into the interior 78 of the can body 76 due to the panel 18 being connected to the tab portion 24 by the second rivet 22. Once the opening 82 has been created by rupturing the score line 16 the rear lifting portion 28 of the tab portion 24 is pressed downwardly which causes the tab portion 24 to return to an initial position. The opening 82 allows the individual to drink the liquid 80 from the can body 76. When the individual wants to close or reseal the opening 82 the individual may grasp the tab portion 24, such as by the rear lifting portion 28, and move or rotate the tab portion 24 to thereby move the panel 18 to cover or close the opening 82. The beverage can 70 may be held, stored, or refrigerated without concern that the liquid 80 will spill out of the beverage can 70 or that the liquid 80 will become stale or that the liquid 80 will be contaminated. When the individual desires to again drink from the beverage can 70 the individual moves the tab portion 24 to again move the panel 18 away from the opening 82 to uncover the opening 82. As is known, once the liquid 80 from the beverage can 70 has been consumed, the beverage can may be recycled.
FIG. 7 depicts another embodiment of a resealable beverage can lid 100 constructed according to the present disclosure. The resealable beverage can lid 100 is shown to comprise a lid 102 connected to a beverage can body 104 by use of a flange 106.
