Abstract: A folding box made of cardboard includes a blank which forms four lateral surfaces, a cover, and a base of a cuboid and which includes four main folding lines which divide the blank into four main surfaces and a securing surface. Each of the main surfaces has a main surface segment, which forms a respective lateral surface of the cuboid after the securing surface is secured to the opposite main surface, and multiple auxiliary folding lines, which run transversely to the main folding lines and each of which connects one of the main surface segments to an auxiliary surface segment. The auxiliary surface segments form the cover and the base of the cuboid.

Abstract: A bristle configuration providing enhanced cleaning of teeth. The bristle pattern includes large tufts having a greater cross-sectional area than standard toothbrush bristle tufts. The large tufts are contoured so that the top ends of the bristles comprising the large tufts are not all at the same height. More than one raised section is provided, the raised sections being spatially isolated from one another to function independently of one another. Preferably, at least one of the raised sections has a sufficient brushing surface area with bristles extending a sufficient height above surrounding bristles such that that raised section can reach into and clean interdental tooth surfaces, preferably while the remaining bristles in the large tuft clean other tooth surfaces. Another aspect of the invention relates to a zig-zag or sawtooth bristle profile, wherein each tuft making up the profile has its own unique substantially conical or frustoconical profile.
