Claims

1. A pouch for storing granules where the perimeter of a front and back pair of synthetic resin films are sealed, wherein: a pouring spout with an easily opened port is formed to protrude out from the top perimeter region of the pouch, and an opening support member is placed at the pour spout, and the front and back pair of synthetic resin films are prevented from mutually contacting by the opening support member in the region where the opening support member is established and surrounding regions thereof, so that the opening of the pour spout is always maintained in an open condition.

2. The pouch for storing granules according to claim 1, wherein the opening support member has a shape selected from a group consisting of (I) hollow cylindrical shapes including hollow round cylinders (a), double chambered cylinders (b) with a partition at the center of the cylinder (a), hollow elliptical cylinders (c), two or more chambered elliptical cylinders (d) with partition in the center of the elliptical cylinder (c), hollow square cylinders (e), hollow rectangular cylinders (f), two or more chambered rectangular cylinders (g) which have partitions at the center of the rectangular cylinder (f) or the like; (II) polygonal pillars with cross-sectional shapes like various letters such as H shaped, I shaped, U shaped or V shaped or the like; or (III) combinations of (I) and (II); and the always open pour spout intake port, formed by the opening support member and the front and back pair of synthetic resin films which are on both sides of the opening support member, is divided into a plurality of flow paths.

3. The pouch for storing granules according to claim 1, wherein the opening support member is located in a position which does not contact with the cut away region of the easily opened port, and the always open pour spout intake port is divided into a plurality of flow paths, but the cut away region (in other words the pour spout discharge port) of the easily opened port is one of those flow paths.

4. The pouch for storing granules according to claim 1, wherein the opening support member is attached to the synthetic resin films which form the pouch by spot seals in at least one or more spots.

5. The pouch for storing granules according to claim 1, wherein the front and back pair of synthetic resin films have a sagging region (swelled region) in the region where the opening support member is located and surrounding regions thereof, formed by plastic working using heating and vacuum.

6. The pouch for storing granules according to claim 1, wherein a fastener is provided for resealing the easily opened port.

7. The pouch for storing granules according to any one of the above claims, wherein the pair of synthetic films are sealed by a method selected from the group consisting of heat sealing, ultrasonic sealing, adhesive sealing, and a combination thereof.
