The invention relates to an insulated container (1) for constant-temperature storage, in particular for constant-temperature transport of
food products, comprising a container (10) with a food product receiving chamber (14) and a lid (16) for closing the insulated container (1). The container (10) comprises a central
magnet (2) located near the bottom (15) thereof, the magnetic properties thereof, in particular the holding force or the magnetic
suction force thereof, and the dimensions thereof being selected, designed and arranged according to the specific requirements of the insulated container (1) such that the insulated container (1) can be fixed by the
magnet (2) in a stable, non-slip and stationary manner in a predetermined position (P, P1, P2), a suitable
metal element or
metal layer (M) is arranged at the position, and the
metal element or metal layer interacts with the
magnet (2). The invention also relates to a
system (1, 2, 3) comprising the above-mentioned stabilized insulated container (1) and at least one cup mat (3) comprising a metal element or metal layer (M) which interacts with the magnet (2) of the insulated container (1).
