A modular lunch box 100 is disclosed, comprising a base 102 to receive containers 104 to store food articles and having one or both of heating and cooling devices; and a top lid 106 removably received on base to cover and individually seal the containers. A control module 110 is detachably received through a first aperture 112 in top lid 106 such that control module 110 rests against a step portion of containers 104 for operative coupling with heating and cooling devices to control their temperature. Without control module 110, lunch box 100 is usable as a conventional lunch box. Control module 110 includes a wireless communication module to receive user inputs to configure the lunch box for heating and/or cooling of food article at desired times, to desired temperatures. A battery pack positioned over top lid 106, gets coupled to control module 110 to meet power requirement.
