Today in 1963, US Patent 3074678 A was issued, an invention of John Michael Mele, for his “Beer Can Holder.” There’s no Abstract, although in the description it includes this summary:

My invention relates to holders for cans containing beverages and more particularly to beer can holders.

As the pouring out of the cold beer into a glas will raise the temperature of the beer and also will reduce its gas content, it is considered preferable by many persons to drink the beer directly from the can through an opening cut in the cover of the can.

One of the important objects of my invention is to provide a convenient handle for the holding of the beer can and thereby eliminate the inconvenience of a direct contact between the fingers and the cold and moist beer can.

Another important object of my invention is to provide a beer can holder which collects the beer which may be accidentally spilled when cutting the opening in the cover of the can, thereby preventing the soiling of the table cover.

A further object of my invention is to provide a beer can holder which is very simple in construction, economical in manufacture, and which offers a very secure clamping of the beer can in the holder, eliminating the possibility of the rotation of the beer can in the holder and the resultant displacement of the discharge opening of the cover in relation with the handle.
