Clicko-Bricks are liquid containers designed for reuse as interlocking smart building blocks. They come in three forms (square; hexagon; triangle) and various sizes. All sizes and forms have built-in integrating & interlocking capabilities in all directions (top & bottom included) with other units in a single structure. Their regular volume ranges between 250 ccl to 4.5 Liters, and as such, they can serve as containers to almost all household needs. The Clicko-Brick containers are produced in the common blow-molding technology, so that manufacturers wishing to produce them would not face exceptional challenges.The containers' connection mechanism may be added along the production line, or, according to a customer's requirements, after the bottles have been used as containers. The mechanism consists of 1-2 straps around the bottle providing a simple, firm, connection mechanism that cannot break apart accidently - The all-sides interlocking mechanism (up and down included) allows for the construction of very large, varied, and flexible structures, with no additional connecting units. For example, when spaces are required in a Clicko-Brick structure (such as for passing infrastructure pipes in a wall), the various sizes allow for that kind of flexible assembly.The ability to create an unlimited number of complex structures makes Clicko-Brick an outstanding multi-purpose product. Various manufacturers (in the fields of construction, agriculture, floating structures, etc.) can design elements & modules that make use of Clicko-Brick as their basic building block.Another advantage of Clicko-Brick is that since it can be filled with various materials (like air, liquids or grained solids) and re-sealed, it's flexible in addressing differing needs, such as weight, buoyancy, fire resistance, thermal & acoustic insulation, and so on.
