After creating a functioning model from plastic and doing a series of tests, I came up with the "Frame-crate 2". This model has improved fixing mechanism that can last for the required period. Also, after the lid is removed the tray has convenient handles. You can see all of it in the video. The tests have also shown that this construction is quite stable and can easily endure not careful use, including dropping.
The main point of this idea is in reduction of the amount of material needed to produce the crate, thus maintaining its stability and rigidity. Keeping the weight of the crate as low as possible we not only provide more comfort for customers but also reduce the amount of fuel needed for transporting, reducing not only the level of emitted CO2 but also the costs.
One of the problems of the normal crate is that you will most definitely need both hands to carry it. On the contrary my design gives you the opportunity to also carry it with only one hand. The handels themselves are much more comfortable to use thanks to their round ergonomic form.
To consider the needs of different households you should provide crates of different sizes. Leaving customers to decide on the number of bottles they want to buy, still having a crate of a matching size.
For a more stable staking there are slots on the edges of the tray and the lid. In this construction all force vectors are divided on the bottles themselves, and the vertical stiffeners can endure a column of a number of crates.
When the crate comes back, it is treated with heat, thus elimitating inner micro cracks and hiding minor scratches on the surface, and friction parts are covered whith a thin layer of polymer. So when you return the crate back to customers it is almost new.
