▎ 摘　　要

NOVELTY - The bag (1) has a compartment (2) defining an interior volume, and a heating unit (4) intended to heat the interior volume of the compartment. The heating unit is made of graphene and intended to be connected to an electrical power supply (6) integrated into the bag or external to the bag. The heating unit is configured to transform electrical energy into heat. A control unit (10) delivers electrical energy from the power supply to the heating unit made of graphene. A temperature sensor is mounted in the internal volume. A double bottom is formed by an outer wall and an inner wall on which a graphene film (8) is placed, where the double bottom delimits a blade of air. USE - Bag for storing and transporting sports accessories i.e. petanque balls, before or during sports practice. ADVANTAGE - The bag can allow the user to heat contents of the bag to a desired temperature and at chosen time to improve use of the objects when the objects are taken out from the bag. The bag can modify certain properties such as temperature, of sports accessories before or during sports practice. The graphene film obtains high thermal results with intrinsic properties of electrical conductivity. The graphene film provides a thin heating medium, that has space-saving, water-repellent and mechanically resistant. DESCRIPTION OF DRAWING(S) - The drawing shows a top view of a bag in an open state and without a receiving unit. 1Storage bag 2Compartment 4Heating unit 6Electrical power supply 8Graphene film 10Control unit
