The invention relates to a self-supporting in a filled state, open-top, zusammenfalt- or-rollbaren and transportable container made of plastic for holding liquids and / or solids, especially storage, landfill or swimming pool, with a bottom and a welded side wall.

Both in Obertags set up containers, especially steel or concrete, as well as underground basin is common to mount or insert plastic for sealing, which have a significant drawback of limited local capacity and bring when used in connection with steel or aluminum tanks also corrosion problems ,

There was a need for a transportable, stowable in an empty state in a small space plastic container for such basins, which can be easily placed on a substantially flat surface and is self-supporting in the filled state, ie the pressure components acting on the side wall absorbs without damage and can be repositioned in another location. This problem is inventively solved in that the material for the bottom and side wall is formed from reinforced with at least one plastic fabric layer plastic.

Other characteristics which may be realized alone or in combination are the following:

Preferably, a plastic Läge on the plastic fabric layer, especially on both sides, laminated or painted. The side wall preferably has at least one fabric layer more than the bottom. Furthermore, at least one fabric layer is made of polyester fabric or contains this. The polyester fabric is preferably formed from monofilament or multifilament yarns. The material for the plastic layers is selected from PVC, polyolefin, in particular PE or PP, or

Polyurethane. At the upper edge of the side wall, a support profile, in particular made of plastic, placed and the support profile is formed as a continuous casting with a longitudinal slot. The support profile stabilizes the upper edge of the side wall by absorbing radial forces and covers it upwards, so that it is protected against damage.

It is essential to use a reinforcing fabric, which has on the one hand the necessary tensile strength, but on the other hand has the necessary elasticity to allow a stowage of the empty container in a small space for transport without damage.

Currently, polyester fabric is preferred for the reinforcing fabric because it optimally meets these requirements and is cheaply available. In this case, the tissue may be substantially planar, but also have a surface texture.

Practical experiments have shown that for a filling height of 120 cm a thickness of the bottom of about 1 mm (0.6 mm) with a reinforcing fabric layer and for the side wall a thickness between 3 and 6 mm (depending on the length of the side wall) with two Armierungsgewebelagen completely sufficient, relatively independent of what makes the plastic so reinforced as long as there is good adhesion between the reinforcement and the plastic, what can be used in a conventional manner adhesion promoter.
