Universal Tray / Product

When we order the mealin the restaurant,we need to put the meals on the trayand then walk to our seats.
Generally in this situation,it is would be a risk to overthrow the meals if they are too heavy,
the moving distance too far, or even go to upstairs and downstairs.

This concept is solving the dishes’ problem that is unstable and easy to overthrow.
There is a hole in the middle of the tray, all we need is put the bottle trough the hole,
the bottle can get stuck to the hole naturally in order to make it stable, it would be adequate to different bottles.
