In Mediterranean countries, during olive harvest season, it is very common for a family to purchase one or two 9 liter tanks of olive oil for the year. Unfortunately, even olive oil will oxidize and begin losing its healthy polyphenols after about a month of exposure to the air. The other issue is trying to lift this large tank and pour it into a smaller bottle for daily use is cumbersome, messy and even dangerous.
Hermet solves both of these problems with its olive oil Razortank. Since it is flexible, the tank gets smaller as the oil is evacuated. Keeping the oil free of oxygen exposure until the tank is empty, dramatically preserving the precious nutrients of the oil.
Secondly, the Hermet tank does not need to be lifted to dispense. The cap is located on the upper part of the tank. The bottle is placed at the tap with one hand and the other hand turns a simple mechanism which squeezes the flexible tank. A one-way valve ensures no oxygen will enter the tank.
