Abstract
The present invention relates to a safeguard zipper bag, and more particularly, to a safeguard zipper bag that has a dual opening part in order to disperse force applied to the zipper bag, such that the safeguard zipper bag is difficult to open by outer opening parts and easy to open by inner opening parts, and the safety of the safeguard zipper bag is improved. A safeguard zipper bag according to the present invention may include: an envelope in the form of a bag; and a male zipper part and a female zipper part attached to inner surfaces of the envelope, in which one portion or the other portion of at least one of the male zipper part and the female zipper part, which is spaced apart, at a predetermined interval, from a portion where the male zipper part and the female zipper part are coupled by male/female engagement, is attached to the inner surface of the envelope. In this manner, it is possible to provide a low-cost, high-efficiency, and safe zipper bag which is not easy to primarily open due to dispersion of force without forming an additional accessory and increasing costs.
