The inflatable sealing device includes an upper inflatable sealing element and at least one side inflatable sealing element which directly or indirectly allow, in the inflated state, a seal between the upper wall of the cell and at least one part of the top face of a set of products positioned in the cell and a seal between at least one side wall of the cell and at least one part of one of the side faces of this set of products. The upper inflatable sealing element and the side inflatable sealing element delimit a single inflatable chamber, and the inflation means allow the upper inflatable sealing element and the side inflatable sealing element to be inflated by blowing air into this single inflatable chamber.
