Aluminium cans

 

Approximately 1 billion are produced in the USA each year. The first can was designed in 1958 by Kaiser Aluminium. This metal proved ideal as it was a lightweight, flexible material that allowed manufacturing of the bottom & sides of the can from a single sheet, leaving the top to be added after the can was filled.

 

The first cans were opened with a separate opener but this was inconvenient so Ermal Fraze designed a small lever attached to the can which was removed as the can was opened.

 

The design was workable but after a while it created an ethical dilemma:

In that time most of people were buy the cans without realizing the hazard could be caused. After sometime people start analyze some hazard for human and environment. Human get injured and environment spoiled.

 

So in 1976 Daniel F. Cudzik invented a simple, stay-attached opener of the sort familiar today.

 

 

As improvements were made in the design & production of aluminium cans, various ethical problems arose concerning:

 

   

     a.      Human safety:

          During store and transportation of bottles maybe catch some dirt so, that could affect human.

 

      b.     Environmental pollution: 

      

        The usage of soft drink will increase so, the waste will increase. Some people do not care which hazard the environment. Recycle is one of the solutions but still need more weariness how is prevent the environment pollution.

         c.      Convenience:   

     

      Much faster and efficient way to dispense and store. Easy to carry and use, especially beneficial for people with back problems or disabilities.

 

 

          d.     Money:

Some companies can redeem many of the cans and bottles they buy. They pay the deposit when they buy the product, so redeeming these empties is a great way to recycle, while putting a little change back in to them.
