Pumping brush / Kitchen appliances

Pumping brush

When some throw away the plastic bottles they bought while they were out, some reuse them for environment. We also carry mugs or tumblers to reduce plastic waste. However, there's a problem when it comes to washing because we cannot clean them with hand in it due to small mouth. To solve this problem, I have designed a brush with inflatable air pocket inside the sponge which we can pump using handle. Size of the brush before inflating is small enough to fit narrow mouth of the bottle but once it inflates, sponge will get big, making it easy to clean the bottle thoroughly. The air can be released by pressing the pump slowly after the use.
