Can I apply for a patent for black cans and bottles of liquor?

Of course. Some liquor bottle caps or their own wine utensils are innovative in structure or technology, and they can apply for patent protection for utility models. The black jar bottle of liquor is innovative to some extent and can be patented. Patent right, referred to as "patent" for short, is an intellectual property right, which is the exclusive right enjoyed by the inventor or his assignee for a specific invention within a certain period of time in a designated area.
