Growing Barrel

Description State of the art:

There are barrels, canisters and drums of every shape and size for liquids of every kind. All of them are characterized by the fact that the empty containers take up a lot of space and therefore require expensive storage space.

Task:

To develop a barrel, canister or barrel that can be folded up and takes up very little space when empty. Stability when full must be guaranteed. The barrel, canister or barrel should also be of the appropriate size to be used as a rain barrel and should also unfold when being filled and fold up automatically when being emptied, for example in the case of rain barrels. This process should always be repeatable. It should be made of a light, strong and stable material.

Solution:

The developed container for liquids has a solid base with a ring-shaped side part 1, approximately 40 cm high. Next to this side part there are two further ring-shaped side parts 2,3 directly next to each other (forming a ring/hoop around the next larger one). These rings/hoops are connected either by the internal accordion-like seal 4, or by guide rails which hold the elements together so that they can be moved up or down. On the last ring there is a floating element 5 attached on all sides. This floating element 5 causes the barrel or drum to float up after the lower segment has been filled. This floating up, caused by the rising liquid level, creates buoyancy which pulls up the next element of the ring-shaped side parts, thereby increasing the volume accordingly. And so on, until it is completely filled to a total height (example) of approx. 120cm 6. The slightly conical shaped tires always result in a stable barrel or drum body.

The sealing of the barrel or drum is ensured by the internal accordion-like lining, which is attached to the lower ring or as an insert and is attached to the upper floating ring or the last, upper ring. Alternatively, a rubber seal on each ring-shaped segment also ensures the necessary tightness.

The barrel, canister or barrel described can be manufactured in any cylindrical shape A, B, C according to the above principle. For example, it is possible to manufacture semi-circular cylinders B according to the above principle, which would be suitable as wall-mounted rain barrels. Triangular, right-angled shapes A can also be manufactured for "corner barrels". A combination of different basic patterns can be put together. It is possible to put four barrels together like pieces of cake and transport them as a unit. At the destination, the clamps holding them together are released and the user has, for example, four different contents available.

For smaller containers, e.g. 5 liter canisters, a solid base with an accordion-like wall and a solid upper part with a closure 7 is sufficient. In order to ensure sufficient stackable stability, a cardboard box will enclose the sides. This canister is, as described above, also suitable for multiple fillings, but can also be disposed of in a space-saving manner after being compressed 8 .

Advantages:

Space-saving, easy to transport, inexpensive to manufacture, e.g. from recycled plastics. The size of the barrel adapts to the volume, no half-empty barrels are transported. Round, semi-round, corner barrels are possible, which can also be used on house walls, for example as rain barrels, to save space. Smaller containers can be disposed of or transported in a space-saving manner if they are pressed together and closed with the lid. The vacuum created prevents the canister from expanding.
