Abstract: A container system which comprises at least one flexible resilient clamp device detachably fixable to a container. The clamp device comprises at least two substantially opposite clamp halves which are at least interconnected at a top part of the clamp device, are adapted to be moved towards each other, and which exert an outward pressure when compressed. The clamp device further comprises in at least one fixation structure adapted to hold the clamp device in a fixed position. The container comprises a bottom plate, at least two substantially parallel side walls, and at least one complementary fixation structure on each opposing side wall for engaging the clamp device fixation structure.

Abstract: Cover for sealing a container which is bounded at the top side by an outward bent top edge, said cover being provided along the periphery with a downward opening groove which encloses the top edge and is bounded by an outside wall, an inside wall, and a top wall connecting said walls, in which the width of the groove at the position of the top wall is less than the deflection of the top edge of the container, and the surface of the groove walls which adjoins the groove is made of a layer of elastic material.

Abstract: The invention relates to a holder provided with a lockable lid and a carrying handle connected with the holder, the ends of which carrying handle are attached to the holder wall, the ends of the carrying handle sticking eccentrically in openings of rotating disks attached to the holder wall, the hand grip part of the carrying handle being positioned in a groove in the lid in a first position of the disks, while in a second position of the disks the carrying handle is clear of the lid.

Abstract: A process and device for collecting and maintaining fresh amounts of rainwater. The device is comprised of a storage vessel having an inlet passage terminating near the bottom of the vessel, which is further provided with an overflow and a drain. The device possesses a through-pipe which becomes positioned in line with sections of a downspout between which the device can be installed. Water is introduced into the vessel via an upper downspout section and a branch pipe and excess water above the vessel's capacity is discharged via an overflow passage directly into the through-pipe and a lower downspout section. The vessel and its parts are preferably made in one piece by blow-molding a plastic material. The device is substantially intended for collecting small amounts of water.
