The invention relates to a compact hot-melt box sealer which incorporates a hot-melt adhesive applicator for optimizing the closure of cardboard boxes. It is distinguished by an innovative device that prevents objects inside the boxes from falling during movement and the application of the adhesive. This device makes it possible to partially reopen the main flaps at the bottom of a filled box, to apply a hot-melt adhesive in a precise manner for ensuring efficient and secure closure, and then to firmly seal the cardboard box. This improves the stability of the contents during the closure process and reduces the risk of the objects moving, thereby ensuring the integrity of the final package.
