DETAILED DESCRIPTION OF THE INVENTION

Certain examples of the devices and methods disclosed herein will be recognized by the person of ordinary skill in the art, given the benefit of this disclosure to provide sanitary, cost-effective containers. In particular, beverage containers are provided that have a sanitary cover, are easier to open than conventional cans, and can be resealed an unlimited number of times. The beverage container of certain examples disclosed herein will prevent the dispensing portion of the beverage container from exposure to the environment and ensure a safe and contaminant-free product. The current manufacturing process for beverage cans may be adapted to include the present invention, with reduced, minimal or no additional cost.

Conventional beverage containers, such as aluminum cans, are manufactured by well-known processes. In one process, aluminum cans are made from an aluminum coiled sheet which is fed through a cupping press that cuts discs and forms them into cup-like containers. These cups drop from the press onto a conveyor, and are fed into an ironing press where successive rings redraw and iron the cup, reducing the sidewall thickness, and achieving a full length can. The tops of the can bodies are then trimmed to eliminate rough edges and ensure height uniformity. The can bodies are then cleaned and dried. Subsequently, the can bodies are labeled and coated with a clear protective layer of varnish. The cans are then baked, treated with a coating, and re-baked. The top portion of each can body is narrowed to form a neck with an outward flange at the top edge. The bottom portions are domed to obtain the strength required to withstand internal pressure if a carbonated liquid will be added to the can. After testing for pin-holes and defects, the can bodies are placed on pallets and shipped to a beverage supplier.

The lids of conventional aluminum cans, typically referred to as “can ends,” are made by stamping shells from an aluminum coiled sheet. The shells are coated with a sealant, and subsequently a rivet is placed in each can end. On those cans using a stay-on-tab type closure, the process further includes inserting a separate piece of metal as the tab under the rivet to secure it in place. The edges of the can ends generally have a curved flange. The can ends are also scored to define the opening of the can end in the finished product. The can ends are then shipped to the beverage supplier, along with the can bodies.

At the beverage supplier, a filling machine is used to pour the beverage into the can body. The process is completed after filling when the can end is added, and secured to the can body by forming a double seam with the can body. A double seam is formed by interlocking edges of the two components, the outward top edge of the can body and the curved flange at the edge of the can end, curling the can end flange around the can body edge so that the can end flange is partially rolled up and under the can body edge to form a partial seam, and crimping and flattening the partial seam against the can body to form a hermetic seal.

Most beverage cans have a stay-on-tab type closure such as those disclosed in U.S. Pat. Nos. 3,967,752 and 3,967,753 to Cudzik, and described above. However, there are many aspects of the conventional stay-on-tab closure that make it undesirable. The stay-on-tab closure does not provide for a sanitary drinking environment because the outer surface of the can and the top of the can, which comprises the stay-on-tab closure, comes into contact with the environment during storage, shipping, distribution, display, handling, and ultimately, use by the consumer. When the beverage is poured directly from the can through the opening formed from the stay-on-tab closure, the beverage comes in contact with the top and surface of the can, making for a potentially unsanitary drinking environment. Additionally, if a consumer drinks the beverage from the can directly, both the beverage and the mouth of the consumer come into contact with the surface and top of the can, also making for an unsanitary drinking environment. Additionally, the stay-on-tab type closure does not allow for reclosing the beverage container.

The present invention provides a beverage container that may be manufactured by commercially available processes and machinery with minimal retrofitting, low material and manufacturing costs, ease of stacking during shipping and storage, increased sanitary conditions of the dispensing portion, reliability and ease of opening and closing by consumers, pourability, drinkability, recyclability, and decreased likelihood of spilling the contents of the container. These advantages of the present invention overcome the noted deficiencies of the conventional stay-on-tab type closure beverage containers.
