Abstract: The toboggan proposed has a device which adjusts the runner to allow the toboggan to negotiate curves, the adjustment being made by means of a steering member in such a way that the radius of curvature of the runners is the same as the radius of the curve to be negotiated. The toboggan may be stopped by an automatic braking member when the steering member is not pulled rearwardly or restrained by the operator of the toboggan.

Abstract: In an hermetically sealed fresh-keeping container for organic substances, in particular foodstuffs, with a dimensionally stable bottom part that incorporates a support surface for the goods that are to be kept fresh, a similarly dimensioned and stable upper part that is mounted on the lower part, above the support surface, so as to be removable. The hood forms a useable space, and a vacuum pump system removes the air within the useable space. The useable space is also delimited by an airproof foil, the edge of which is releasably connected with a wall of the container. A suction opening of the vacuum system is incorporated in this wall.
