Abstract

Le problème décrit par la présente invention est de fournir un dispositif de nettoyage pour un récipient, apte à nettoyer l'intérieur du récipient par pulvérisation de celui-ci, avant d'être éliminé, avec un liquide de nettoyage sans que de l'eau ne fuie autour du récipient, tout en économisant de l'espace, réduisant le besoin de maintenance, et réduisant le coût en réduisant relativement l'échelle du dispositif. À cet effet, l'invention porte sur un dispositif de nettoyage pour un récipient, lequel dispositif comprend : une table de montage pourvue d'une surface de montage avec laquelle un bord d'ouverture d'une paroi périphérique du récipient entre en contact ; un boîtier dans lequel la table de montage est montée de manière à être mobile dans la direction de montage ; un élément élastique qui est monté sur le boîtier et qui est destiné à pousser la table de montage le long de la direction de montage ; un mécanisme de nettoyage qui est monté sur le boîtier et pulvérise le liquide de nettoyage sur les surfaces internes de la section inférieure et de la section de paroi périphérique du récipient ; et un moyen de commande pour pulvériser le liquide de nettoyage sur les surfaces internes de la section inférieure et de la section de paroi périphérique par l'intermédiaire du mécanisme de nettoyage lorsque la table de montage est abaissée d'une distance prédéterminée.
