The concept of aerosol originated in 1862 when Lynde proposed the preparation of pressurized packaging with a saturated solution of gas. It was not until 1926 that the Norwegian chemical engineer Erik Rotheim prepared the prototype of the aerosol in the modern sense from liquefied gas.

Some people may find out why the aerosol can is different from the jar we usually see, and why the bottom of the aerosol can is bent ？

(1) Strengthened the structure of the can. If the aerosol can is flat-bottomed, the pressure of the high-pressure gas may squeeze the metal bottom into an outwardly raised shape. Curved tank bottoms have better structural integrity, like arches or domes in buildings.

(2) Disperse the pressure. With the bottom bending shape, most of the force applied to the upper part of the bending metal is dispersed to the sturdy bottom edge of the can.

(3) Make the product material easier to consume cleanly. Draining a flat bottom is like sucking out the last little pool of water in a glass with a straw. You have to tilt the can so that the product material can be gathered under the plastic catheter. With the curved bottom design, the last bit of product ingredients is concentrated in a small area on the bottom edge of the can. This makes it easier to empty all liquids.
