The canned type can was patented in 1810 by an English inventor named Peter Durand. This invention was not related to food manufacturing and the inventor sold his patent to other people, who started making canned goods commercially in 1813 and packed food destined for the British Navy.
In its early days, cans were sealed using lead solder, this material is extremely toxic. The first can opener was invented in 1855.

The body is the rectangular, cylindrical or irregular part that makes up the walls of the container.
It is the lateral union of the container body. It is usually achieved through electric welding although it can also be obtained with the intervention of a seaming process in which a thermoplastic sealing cement is provided.
This is the radius of the arch of the eyelash that connects it to the rest of the body.
Flange that introduces the body at all ends of the can. It is made up of a flat area, practically perpendicular to the wall of the container body, next to an arch that connects this flat area with the aforementioned body.
Bottom of the Container
Final portion of the curl. In it is exposed steel, which gives it sensitivity to the oxidation of the can.
External part of the bottom that is deformed while the closing operation is carried out and transfers its integration into the closure.
It is the lateral partition that establishes limits in the bottom cavity, allowing the closing mandrel to be stored.
Rubber or sealing compound
This is a substance formulated with synthetic rubber based materials. It favors the hermetic seal of the closure. This is applied to the portion of the inner part of the bottom wing, as explained by the wiki in its publication on aluminum: https://es.wikipedia.org/wiki/Aluminio
Bucket Wall Radius
It is an arch that joins the lower portion of the wall that has the basin next to the panel in the central area of the bottom.
It is the distance that exists between the top of the wing when the bottom is loose and the closure when this is done, reaching the central panel located at the bottom. It must be measured at the point where the radius belonging to the bottom basin ends.
Curvature that is directed towards the inside of the end located in the bottom area. While closing, the loop is used to start creating the bottom hook.
This arch connects to the upper portion that has the wall belonging to the basin next to the wing.
Characteristics of Aluminum Cans
Metal containers, specifically aluminum (and its electronic configuration) , have adequate characteristics for packaging food, which are:
- Hermetic : They offer protection from oxygen, air and bacteria that can be contaminating sources to the contents inside the can.
- Lightness : Its thickness has an approximate measurement of 0.10 millimeters.
- They are resistant to breakage.
- Protect the content : They have protection and sealing against light.
- Inviolability : It is not possible to open the can without observing that it has been previously manipulated.
- It has a rapid cooling.
- Decorable : It is possible to personalize the can through the printing of lithographs.
- Recyclability : The can can be recycled in the aluminum and steel sectors. Although the collection rate of the can is currently lower than that of other materials, such as cardboard and paper.
