A vacuum flask (also known as a Dewar flask, Dewar bottle or Thermos) is an insulating storage vessel which keeps its contents hotter or cooler than its surroundings.
The vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which prevents heat transfer by conduction or convection.

Can there be further enhancements in Vacuum Flask Design ?.

Other than "Concentric Cylindrical" Geometrical Shape of the Vacuum Flask, which other Geometrical Shapes can be taken as an alternatives viz Cube within Cube, Cone within Cone, Sphere within Sphere ?
i.e. Concentric Cube, Concentric Cone, Concentric Sphere.

I Feel the Concentric Cube, Concentric Cone, Concentric Sphere might work as alternatives for constructing/manufacturing Vacuum Flasks.

Thanks & Regards,
