In 1959, ERNIE.C.FRAZE (Emar Clinian Fraze) of DRT Company in Deaton, Ohio, USA, invented the aluminum can, which is to use the material of the aluminum can lid itself to form a rivet, a pull ring is covered and riveted, and a corresponding notch is added to form a complete aluminum can lid. This genius invention has made a historic breakthrough for metal containers after 50 years of long development. At the same time, it has also laid a solid foundation for the development of canning and beverage industries. Aluminum cans originated in the United States and are popular in the United States. So how are aluminum cans made? Let's learn about it together~
Aluminum cans are a common packaging container, generally used to load various beverages and foods. Its basic structure includes the following parts:
Can body: The main part of the aluminum can, generally made of metal (such as iron) or aluminum alloy, with a certain rigidity and durability. The can body is usually cylindrical, closed at the top and open at the bottom.
Top lid: located on the upper part of the can body, used to close the can body. The top cover is generally made of a metal cover sheet, which can be made of aluminum alloy or other materials, and has certain sealing and corrosion resistance.
Pull ring: a part located on the top lid, used to open the aluminum can. The pull ring is usually made of metal or plastic, and the aluminum can lid can be opened by rotating or tearing.
Pull ring support: an arc-shaped raised part located on the top of the can body, used to support the pull ring. The pull ring support is usually made of metal or plastic to ensure that the pull ring can be firmly fixed on the top lid.
Inner coating: the coating inside the aluminum can, used to prevent food from contacting metal, preventing food from spoiling or being contaminated by metal. The inner coating is usually made of food-grade plastic or resin.
Bottom lid (generally refers to tin cans): the closed part located at the bottom of the can body, used to seal the can body. The bottom cover is generally made of metal and is usually connected to the can body by welding or sealing.
In addition to the above basic structural parts, aluminum cans may also include some other accessories, such as folding straws, damping pads, etc., to provide a more convenient use experience. Overall, the basic structural design of aluminum cans is relatively mature and standardized, which can effectively protect the safety of food and the convenience of using aluminum cans.
