Abstract: The present utility model relates to a sleeve connector (100) for joining tubular metal posts (300), comprising locking regions (120) provided with a ring of locking protuberances (121) of height (ht), which corresponds to from 0.15 to 4% of the external diameter (D) of the locking region (120) in order to promote the locking together of the ends of the tubular metal posts (300) by means of the mechanical deformation of the locking protuberances (121).

Abstract: The present invention relates to a disinfection composition, particularly for lasting disinfection of synthetic fibers, synthetic surfaces, metallic surfaces and composite surfaces, and similar surfaces, said disinfection composition comprising at least one disinfectant, at least one fat- and residue-removing component, at least one additional protection component and additional components which are compatible with the above components and have low or no toxicity. The invention further relates to a disinfection method, to a specific tooth brush disinfection protocol and finally, to a corresponding disinfection product.

Abstract: A toothbrush sanitation device includes a base with a container for immersing toothbrush bristles in a sanitizing, disinfecting or cleaning fluid and a lid. The base includes a perimeter flange with an annular protrusion and an annular cavity that are circular and concentric to the base and has a height that is 20% to 40% of the total height of the device. The container has a cylindrical inner wall with a rounded bottom and a conical outer wall which tapers toward an open end of the container, and has one or more level tags indications. The lid has a column and a fitting zone disposed in an open end adjacent to the column. An inner wall of the fitting zone is cylindrical, and the external taper of the container and the internal cylindricity of the fitting zone define a locking line.
