Claim:
A buffer air column with a three-dimensional structure, comprising: a first buffer portion, bent to form an accommodation space, used for accommodating an article, and comprising: a plurality of first air columns, each comprising a first surface and a second surface opposite each other, wherein the first surface faces the accommodation space; a plurality of first heat sealing sections, for heat-sealing the first air columns; a plurality of second heat sealing sections, for heat-sealing the first air columns, and disposed at an interval from the first heat sealing sections; and a second buffer portion, comprising: a plurality of second air columns, each stacked on the second surface of the first air column; a plurality of first connection sides, located at the second air columns, wherein one end of the first connection side is connected to the first heat sealing section, and a first angle is formed between the first connection side and the first air column; a plurality of second connection sides, located at the second air columns, and disposed at an interval from the first connection sides, wherein one end of the second connection side is connected to the second heat sealing section, and a second angle is formed between the second connection side and the first air column; and a corner area, with one end connected to the first connection side and the other end connected to the second connection side, and used for abutting against an inner surface of a case body, wherein a buffer slot is formed between the second air column and the first air column, and when the article abuts against the first air columns, the first air columns buffer and protect the article, and the buffer slot is compressed due to the pressure and assists in buffering and protecting the article.
