Benefits of technology

The invention is a zipper suitcase that is automatically produced, by improving the product structure. The front and rear strips are made of hard material, replacing the conventional soft strips, and a protrusion and recessed portion reinforces the strength of the suitcase. This makes the suitcase more secure when loaded with luggage, minimizing instability. The thickness and shape of the rubber strips can be adjusted to accommodate different sizes of suitcases.

Problems solved by technology

However, the zipper needs to be manually sewn during the current manufacturing, which requires more manpower and cannot realize automatic production.
