Abstract
A resealable sachet that is designed to contain substances of liquid or creamy consistency and which after opening and partial use of the contents, may be easily resealed and which thereby prevents the leakage of the remaining contents and which can be easily and economically manufactured. The sachet consists of two essentially parallel arranged layers made of flexible film-like material with given outer contours which are connected tightly at least at their edges and which form an enclosed volume to be filled with the substance. A part of the enclosed volume is formed as a narrow outlet channel within an opening strap leading to the edge of the sachet and is sealed by a tear-off section. At least one sealed side of the sachet adjacent to the outlet channel strap has a holding slit whose length is adjusted to the width of the outlet channel strap. The position of the holding slit is arranges so that the folded opening strap can be pulled through the holding slit with at least one part of its length to reseal the sachet.
