Beverage Can's Top Having A New Stay-On-Tab For Opening Both A Drinking Hole And An Air Hole Thereon
In an exemplary embodiment of the present invention, there is disclosed a beverage can's top having a new tab design which would be the tool that could allow for the opening of both the drinking hole and air hole in the can's top. The tab may have different shapes and sizes. The length of the tab may be varied to facilitate the efficiency of the opening. The locations of the air hole and drinking hole are within the range of the can tab.
1. Field of the Invention
This invention relates generally to a beverage can's top and means for opening and, more particularly to a beverage can's top and a new stay-on-tab for severing both a large and small frangible portions thereon and creating a drinking hole and an air hole on the can's top respectively.
2. Description of Related Art
Typically, a beverage can is made of aluminum for holding beverage such as a carbonated soft drink, and alcoholic beverage, etc. An easy open beverage can normally employs one of several types of opening mechanisms that are affixed to the beverage can's top to open a drinking hole on the top.
Most of current easy opening beverage cans have a stay-on-tab opening mechanism. The mechanism uses a separate tab attached to the upper surface as a lever to push in a scored part of the top, creating an opening for the beverage to flow out of the can.
One recent modification to can design was Miller Coors' introduction of the Miller Lite's second hole on the top for air passage. The idea of a can that uses a second hole for air passage is not new for beverage cans. The air hole can be traced back to the beverage cans without tabs; they were opened by a can piercer, which punched two holes in the top—a large one for drinking, and a small one for air passage.
However, the Miller Lite's design requires a user to use their keys or some other self-provided object to puncture that second hole and a user has to press that object hard enough to open the air hole.
It is desirable to have a new tab design that allows for the opening of both frangible portions in the can's top without the need for additional tools or the need to use brute force.
SUMMARY OF THE INVENTIONIn an exemplary embodiment of the present invention, there is disclosed a new tab design which would be the tool that could allow for the opening of both drinking hole and air hole in the can top. The tab may have different shapes and sizes. The length of the tab may be varied to facilitate the efficiency of the opening. The locations of the air hole and drinking hole are within the range of the can tab.
The tab allows for some leverage to be used to open the air hole after the main drinking hole has been opened, thereby requiring less brute force to open the air hole.
In one embodiment, the new designed tab has a several millimeter “protrusion” on the back side of the tab typically where a person's index finger would be located to open the can. There are two purposes for this protrusion: one would be to make it easier to lift the tab to open the large frangible portions (drinking hole), and the second would be to facilitate the opening of the second small frangible portion (air hole) in the can to allow for air flow into the can, resulting in faster and smoother pouring.
In another embodiment, the new designed tab may be rotated around a rivet after the drinking hole is opened to open the air hole.

Additional features of the invention will be described hereinafter and will form the subject matter of the claims that follow.

Referring to
The rivet 16 functions as a fulcrum for the tab 20 to pivot about and the tab 20 functions as a lever to facilitate opening of both the frangible portions 12, 14. When the tab's narrow end 22 is lifted up, the tab's wide end 21 is tilted towards the large frangible portion 12 and severs the large frangible portion 12 of the top, which folds beneath the top plate 10 of the can and out of the way of the resulting drinking hole for liquid to flow out. Similarly, the tab would allow for some leverage to be used to open the small frangible portion as an air hole after the large frangible portion is opened as a drinking hole, thereby requiring less brute force to open the small frangible portion. When the tab's wide end 21 is lifted up; the tab's narrow end 22 is tilted towards the small frangible portion 14 and severs the small frangible portion 14 of the top, creating an air hole.
In the first embodiment (
In the second embodiment (
The tip of the tab's narrow end 22 must be smaller than the size of the small frangible portion 14; otherwise, it won't be able to sever the small portion 14. The tip may be of different shapes as shown in
In another embodiment (
The small frangible portion 14 for the air passage may be located in different positions. It may be 180 degrees apart from the drinking hole as shown in
The tab's small tip 23 for opening must be smaller than the size of the small frangible portion 14; otherwise, it won't be able to sever the small portion 14. The tip 23 may be of different shapes as shown in
In overall, the tab 20 may have different shapes and sizes and, more particularly the length of the tab 20 may vary to enhance the functionality of the tab 20.
The construction of a typical stay-on-tab and the process of placing it on the top plate 10 of the beverage can are well known to those with ordinary skill in the arts.
While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiments, it will be understood that the foregoing is considered as illustrative only of the principles of the invention and not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obvious modifications or variations are possible in light of the above teachings.
