Abstract: A substantially spherical hollow body, having a diameter of from 37 mm to 45 mm, in particular a diameter of 39.7 mm to 40.75 mm, and a weight of from 2.5 g to 3.5 g, in particular a weight of 2.6 g to 2.85 g, comprising a shell and an inner hollow space, wherein the shell has a wall thickness of 0.2 mm to 1.3 mm, in particular 0.3 mm to 0.8 mm, characterized in that the shell is free of celluloid and comprises at least one styrene-containing copolymer.

Abstract: A container for accommodating a liquid, in particular a deodorant roller, has a container jacket, a discharge opening arranged in the container jacket, a supporting and holding unit which is arranged on the container jacket and which encloses a flow channel connected to the discharge opening, and a ball arranged such that the ball can rotate in the supporting and holding unit and is able to seal off said flow channel with respect to the surroundings of the container is provided herein. Formed between the supporting and holding unit and the ball are at least three contact areas, which run around the ball and are formed substantially parallel to one another. Preferably, at least two contact areas are formed as a supporting and holding areas, and at least one contact area as a sealing area.

Abstract: The invention relates to a container (1) for accommodating a liquid, in particular a deodorant roller, has a container jacket (2), a discharge opening (3) arranged in the container jacket (2), a supporting and holding unit (4) which is arranged on the container jacket (2) and which encloses a flow channel (5) connected to the discharge opening (3), and a ball (6) arranged such that the ball can rotate in the supporting and holding unit (4) and is able to seal off said flow channel (5) with respect to the surroundings of the container (1). Formed between the supporting and holding unit (4) and the ball (6) are at least three contact areas (7), which run around the ball (6) and are formed substantially parallel to one another. Preferably, at least two contact areas (7) are formed as a supporting and holding areas (8), and at least one contact area (7) as a sealing area (9).
