Benefits of technology

[0008]The subject application provides for a container for storing materials for human consumption, comprising: 1) a bottom piece comprising i) a cylindrical side wall portion, ii) a bottom portion, iii) an opening opposite the bottom portion, iv) a threaded section of the cylindrical side wall portion towards the opening, b) a first expansion piece threadedly connectable to the bottom piece, having an outer diameter substantially similar to the outer diameter of the cylindrical side wall portion of the bottom piece, comprising i) a cylindrical outer surface, ii) a first opening oriented towards the opening of the bottom piece, iii) a second opening opposite the first opening, iv) a first threaded section towards the first opening complementary to the threaded secti

Problems solved by technology

However, these plastic bottles are typically discarded within a week because they get dirty and bacteria-infested over time.

There are commercially available bottles which are more robust than the disposable store-bought version, however, they are not easy to clean.

In addition, these bottles are generally plastic, and may contain Bisphenol A (BPA), a very toxic substance.

However, commercially available stainless steel containers, such as those available from Klean Kantine (www.kleankantine.com), only come in one size.

Another drawback of these containers is that they are difficult to clean, since the opening of the container is much smaller than the largest diameter of the container.

As a result, a typical consumer would rinse the bottle with soapy water to clean and leave unwanted residue inside the container.
