Abstract
A zippered bag comprises a main bag body having first and second opposing face members, a top, a bottom, and first and second opposing sides; and a zipper disposed on the main bag body. The zipper extends from the top to one of the first and second opposing sides so as to be oblique relative to the top. The zipper may comprise a male track and a female track engageable therewith. The male track and the female track may be formed by an injection molding. Each of the male track and the female track may comprise a main portion and end portions provided on opposite ends of the main portion, each of the end portions having a smaller height than that of the main portion.The main bag body may have a sealed zone, which is placed on the outer side of the zipper and has an opening guide portion, which is provided in parallel with the zipper so that the sealed zone is to be easily torn open along the opening guide portion.
