Memo is a set of toiletries packaging designed for toothpaste, shower gel and shampoo. The principle of this packaging is based on the memory effect of polymere material and the force of a tensile metal element. To open the packaging, a metal strip sealed into the plastic near the opening has to be removed. The resulting opening is held closed only by the memory effect of the material or the force of the metal element. When the tube is squeezed, the memory effect of the material and the force of the tensile metal element are exceeded and the toothpaste can pass through the opening. To close the tube there is no cap needed, just avoid squeezing the packaging. The force of the metal element can be adjusted through the force of its pre-tension.
