ballom conector

I started with the idea that this mechanism must be mechanical and simple. I wanted to eliminate the use of screws, electronic devices and data transmission (I think it fails to be a Faraday cage) as well as exposure to salt, water etc... This mechanism consists of two parts. The green part is of stainless steel metal, and withstands weather well. It is fitted to the bottom of the container. The other piece is the coupling, which consists of a piece homologous ( grey ) to each other and a cavity that carried a rubber (purple) is a metal ring at the upper end (blue). **** I don't know what you're trying to say here, I'm not sure how to rephrase. Can you show me a picture? The rubber will work like a ballom. **** balloon? When a weight is applied a new shape is taken. The ring at the botom of the rubber is divided into four pieces to facilitate the opening and closing of the hole. It is just an idea that does not need a large infrastructure to do it, do not need to change much the container.*** In this way the container does not need to change much in order for... Another thing to keep in mind is the traction and resistance of the rubber.
