This design is thermos flasks with symbols for heat transfer mechanisms. The vacuum or Dewar or Thermos flask works by blocking conduction, convection and radiation of heat between the inside and the outside. To achieve this, in addition to the vacuum gap between the inner and outer flask shells, it uses insulation on the plug and supporting struts and reflective surfaces on internal layers. So, whatever is stored within the flask can remain hotter *or* colder than the environment without for much longer than if it were unprotected from energy exchanges. … See my profile index or tags for similar designs: • 3700452 = alternative weather version (http://www.spoonflower.com/fabric/3700452) • science (http://www.spoonflower.com/profiles/sef?shop_selection=tag&tag=science)
