A container comprises a container body for containing contents to be heated or cooled, a thermic module at one end of the body, and a closure at the other end of the body. Within the thermic module, an internal exothermic (or, alternatively, endothermic)
chemical reaction is initiated to heat its contents when a user actuates the thermic module. The thermic module includes a
heat exchanger portion extending proximally into the container and a thermic module cap distal to the
heat exchanger portion. The
heat exchanger portion has a pleated wall to improve the
heat transfer to the contents of the container. The container includes a rotatable cover adhered to the container end over the closure with heat-sensitive
adhesive that prevents a user from accessing the contents until a certain temperature is reached. The container further includes a full panel pull-off which covers and protects the
actuator from being actuated until the pull-of lid is removed from the full panel pull-off. The thermic module may also include a filter disposed in interfering relation with the thermic module vents, including a portion between the inner and outer
actuator buttons, to block egress of any particles of the
solid reactant or the
reaction product.
