A method of sealing a plug with a food sauce dispensing cartridge enables leak proof operation of the dispensing cartridge at the site of the plug. The plug, having a circumferential edge, is positioned within the dispensing cartridge and oriented such that the edge is adjacent to the cartridge sidewall. A layer of hot melt adhesive is then applied to the circumferential edge and flows into a gap created between the plug and the cartridge sidewall at a sidesearn formed by an overlap region of the cartridge sidewall. The hot melt adhesive subsequently bonds the plug to the cartridge sidewall and prevents food sauce from moving past the circumferential edge of the plug and out of a containment region.

L'invention concerne une méthode destinée à réaliser l'étanchéité d'un bouchon et d'une cartouche de distribution de sauce alimentaire. Cette méthode permet le fonctionnement sans fuite de la cartouche de distribution, à l'emplacement du bouchon. Le bouchon, doté d'un bord circonférentiel, est positionné à l'intérieur de la cartouche de distribution et orienté de sorte que le bord soit adjacent à la paroi latérale de la cartouche. Une couche d'adhésif thermofusible est ensuite appliquée sur la bord circonférentiel et s'écoule dans l'espace créé entre le bouchon et la paroi latérale de la cartouche, au niveau d'un joint latéral formé par une zone de chevauchement de la paroi latérale de la cartouche. L'adhésif thermofusible colle subséquemment le bouchon à la paroi latérale de la cartouche, et empêche que de la sauce alimentaire ne dépasse le bord circonférentiel du bouchon et ne sorte hors de sa zone de confinement.
