Foldable bag with defined shape and mat - consists of rectangular mat divided into twelve fields by folding edges that zips into a bag

摘要

A rectangular, plane mat is divided into twelve rectangular fields (A-M) by seams, weld seams or other folding edges. The fields are arranged in three columns and four rows. At least two square fields (G,H) on the outside have diagonal folding edges. The bands of a zip with a common start (15) and end (16) are sewn along (14) edges (1) to (14) of six fields (A-F) with each band on seven edges. By fastening the zip the mat converts to a bag with four fields (A-D) forming the side panels, one (E) the bottom and one (F) the top. Six fields (G-M) are only used to extend the mat's size and may be omitted.
