A vented pouch arrangement is described which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections; along ends thereof, to form a base by which the arrangement can be stood up during use. Preferably, the arrangement is provided with a rib and trough closure arrangement extending thereacross. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. A method for formation of such a pouch arrangement, and methods of use, are also described.

1. A pouch arrangement comprising:(a) first and second, opposed, panel sections; (i) said first and second panel sections being sealingly secured to one another to form a pouch construction having an exterior surface and defining an interior; (ii) said first and second panel sections being secured together to form an end seal and to close a first end of said pouch construction; (A) said end seal being selectively removable from a remaining portion of said pouch construction, when access to said pouch construction interior is desired; (b) a base gusset member; (i) said base gusset member being between said first and second panel sections, to close a second end of said pouch construction; (ii) said base gusset member being constructed and arranged to support said pouch construction in a standing orientation, on said base gusset member; (c) a rib and trough closure arrangement being oriented between said end seal and said base gusset member; (i) said rib and trough closure arrangement being constructed and arranged for selective closure of said pouch construction at said first end, when said end seal has been removed; (d) said pouch construction interior being at least partially filled with coffee beans; (i) said coffee beans filling said pouch construction interior between said base gusset member and a level below said rib and trough closure arrangement when said pouch construction is in a standing orientation; and (e) a gas vent arrangement oriented on said first panel section; said gas vent arrangement being constructed and arranged for selective flow of gas outwardly therethrough from said pouch construction interior, in response to a selected greater than ambient gas pressure within said pouch construction interior when closed; (i) said gas vent arrangement comprising at least one pore in said first panel section and covered by a control member; (A) said gas vent arrangement being oriented on said first panel section between said rib and trough closure arrangement and said base gusset member to permit said control member to selectively control passage of gas from said coffee beans through said at least one pore.
