CA 2626343

A cleaning tool which, even if the distance from the center of a cavity to be cleaned to the inner wall surface defining the cavity varies, can clean the inner wall surface, can be pressed to the inner wall surface with a force having a varying magnitude, can clean the inner wall surface with force with the magnitude most appropriate for the degree of dirtiness of the wall surface, and can clean the inner wall surface only by being moved in the advance-recede direction relative to the cavity. The cleaning tool (1) has a core member (10) and a cleaning section (20) attached along the outer periphery of the core member (10). The cleaning section (20) has cleaning members (30) and a holding member (40). The cleaning members (30) are made from an elastic body, have a larger diameter than the diameter of an opening of the cavity (101), and have continuous annular outer surfaces. The holding member (40) has a smaller diameter than the opening of the cavity (101) and holds the cleaning members (30). The cleaning members (30) and the holding member (40) are installed on the core member (10) so as to be interchangeable and rearrangeable relative to each other.

La présente invention concerne un outil de nettoyage qui peut, même si la distance séparant le centre d'une cavité à nettoyer de la surface de la paroi interne définissant la cavité varie : nettoyer la surface de la paroi interne ; être comprimé contre la surface de la paroi interne à l'aide d'une force de grandeur variée ; nettoyer la surface de la paroi interne avec une force dont la grandeur correspond au degré de saleté de la surface de la paroi ; et nettoyer la surface de la paroi interne seulement s'il est déplacé suivant la direction avancement-retrait par rapport à la cavité. L'outil de nettoyage (1) comprend un élément noyau (10) et une section de nettoyage (20) fixée le long de la périphérie externe de l'élément noyau (10). La section de nettoyage (20) possède des éléments de nettoyage (30) et un élément de retenue (40). Les éléments de nettoyage (30) sont obtenus à partir d'un corps élastique, possèdent un diamètre supérieur à celui d'une ouverture de la cavité (101) ainsi que des surfaces externes annulaires continues. L'élément de retenue (40) possède un diamètre inférieur à celui de l'ouverture de la cavité (101) et retient les éléments de nettoyage (30). Les éléments de nettoyage (30) et l'élément de retenue (40) sont installés sur l'élément noyau (10) de manière pouvoir s'interchanger entre eux et se réarranger les uns par rapport aux autres.
